A new flag + `CLIENTWRITE_EOS` was added for the last client write. This allows + writers to verify that they are in a valid end state. The chunked + decoder will check if it indeed has seen the last chunk. + + The general response handling in `transfer.c:466` happens in function + `readwrite_data()`. This mainly operates now like: + + ``` + static CURLcode readwrite_data(data, ...) + { + do { + Curl_xfer_recv_resp(data, buf) + ... + Curl_xfer_write_resp(data, buf) + ... + } while(interested); + ... + } + ``` + + All the response data handling is implemented in + `Curl_xfer_write_resp()`. It calls the protocol handler's `write_resp()` + implementation if available, or does the default behaviour. + + All raw response data needs to pass through this function. Which also + means that anyone in possession of such data may call + `Curl_xfer_write_resp()`. + + Closes #12480 + +Daniel Stenberg (13 Jan 2024) + +- RELEASE-NOTES: synced + +- TODO: TFTP doesn't convert LF to CRLF for mode=netascii + + Closes #12655 + Closes #12690 + +- gen: do italics/bold for a range of letters, not just single word + + Previously it would match only on a sequence of non-space, which made it + miss to highlight for example "public suffix list". + + Updated the recent cookie.d edit from 5da57193b732 to use bold instead + of italics. + + Closes #12689 + +- docs: describe and highlight super cookies + + Reported-by: Yadhu Krishna M + + Closes #12687 + +- configure: when enabling QUIC, check that TLS supports QUIC + + Most importantly perhaps is when using OpenSSL that the used + build/flavor has the QUIC API: the vanilla OpenSSL does not, only + BoringSSL, libressl, AWS-LC and quictls do. + + Ref: https://github.com/curl/curl/commit/5d044ad9480a9f556f4b6a252d7533b1ba7f + e57e#r136780413 + + Closes #12683 + +Stefan Eissing (11 Jan 2024) + +- vquic: extract TLS setup into own source + + - separate ngtcp2 specific parts out + - provide callback during init to allow ngtcp2 to apply its defaults + + Closes #12678 + +Sergey Markelov (11 Jan 2024) + +- multi: remove total timer reset in file_do() while fetching file:// + + The total timer is properly reset in MSTATE_INIT.

These, depending on transfer state (CONNECT/DO/DONE/ etc.), + return sockets to monitor and flag if this shall be done for POLLIN + and/or POLLOUT. + + Due to this design, sockets and flags could only be added, not + removed. This led to problems in filters like HTTP/2 where flow control + prohibits the sending of data until the peer increases the flow + window. The general transfer loop wants to write, adds POLLOUT, the + socket is writeable but no data can be written. + + This leads to cpu busy loops. To prevent that, HTTP/2 did set the + `SEND_HOLD` flag of such a blocked transfer, so the transfer loop cedes + further attempts. This works if only one such filter is involved. If a + HTTP/2 transfer goes through a HTTP/2 proxy, two filters are + setting/clearing this flag and may step on each other's toes. + + Connection filters `get_select_socks()` is replaced by + `adjust_pollset()`. They get passed a `struct easy_pollset` that keeps + up to `MAX_SOCKSPEREASYHANDLE` sockets and their `POLLIN|POLLOUT` + flags. This struct is initialized in `multi_getsock()` by calling the + various `getsocks()` implementations based on transfer state, as before. + + After protocol handlers/transfer loop have set the sockets and flags + they want, the `easy_pollset` is *always* passed to the filters. Filters + "higher" in the chain are called first, starting at the first + not-yet-connection one. Each filter may add sockets and/or change + flags. When all flags are removed, the socket itself is removed from the + pollset. + + Example: + + * transfer wants to send, adds POLLOUT + * http/2 filter has a flow control block, removes POLLOUT and adds + POLLIN (it is waiting on a WINDOW_UPDATE from the server) + * TLS filter is connected and changes nothing + * h2-proxy filter also has a flow control block on its tunnel stream, + removes POLLOUT and adds POLLIN also. + * socket filter is connected and changes nothing + * The resulting pollset is then mixed together with all other transfers + and their pollsets, just as before. + + Use of `SEND_HOLD` is no longer necessary in the filters. + + All filters are adapted for the changed method. The handling in + `multi.c` has been adjusted, but its state handling the the protocol + handlers' `getsocks` method are untouched. + + The most affected filters are http/2, ngtcp2, quiche and h2-proxy.

You therefore need to tell us: + + - your operating system's name and version number + + - what version of curl you are using (`curl -V` is fine) + + - versions of the used libraries that libcurl is built to use + + - what URL you were working with (if possible), at least which protocol + + and anything and everything else you think matters. Tell us what you expected + to happen, tell use what did happen, tell us how you could make it work + another way. Dig around, try out, test. Then include all the tiny bits and + pieces in your report. You will benefit from this yourself, as it will enable + us to help you quicker and more accurately. + + Since curl deals with networks, it often helps us if you include a protocol + debug dump with your bug report. The output you get by using the `-v` or + `--trace` options. + + If curl crashed, causing a core dump (in Unix), there is hardly any use to + send that huge file to anyone of us. Unless we have the same system setup as + you, we cannot do much with it. Instead, we ask you to get a stack trace and + send that (much smaller) output to us instead. + + The address and how to subscribe to the mailing lists are detailed in the + `MANUAL.md` file. + +## libcurl problems + + When you have written your own application with libcurl to perform transfers, + it is even more important to be specific and detailed when reporting bugs. + + Tell us the libcurl version and your operating system. Tell us the name and + version of all relevant sub-components like for example the SSL library + you are using and what name resolving your libcurl uses. If you use SFTP or + SCP, the libssh2 version is relevant etc. + + Showing us a real source code example repeating your problem is the best way + to get our attention and it will greatly increase our chances to understand + your problem and to work on a fix (if we agree it truly is a problem). + + Lots of problems that appear to be libcurl problems are actually just abuses + of the libcurl API or other malfunctions in your applications. It is advised + that you run your problematic program using a memory debug tool like valgrind + or similar before you post memory-related or "crashing" problems to us. + +## Who will fix the problems + + If the problems or bugs you describe are considered to be bugs, we want to + have the problems fixed. + + There are no developers in the curl project that are paid to work on bugs. + All developers that take on reported bugs do this on a voluntary basis. We do + it out of an ambition to keep curl and libcurl excellent products and out of + pride. + + Please do not assume that you can just lump over something to us and it will + then magically be fixed after some given time. Most often we need feedback + and help to understand what you have experienced and how to repeat a + problem. Then we may only be able to assist YOU to debug the problem and to + track down the proper fix. + + We get reports from many people every month and each report can take a + considerable amount of time to really go to the bottom with. + +## How to get a stack trace + + First, you must make sure that you compile all sources with `-g` and that you + do not 'strip' the final executable. Try to avoid optimizing the code as well, + remove `-O`, `-O2` etc from the compiler options. + + Run the program until it cores. + + Run your debugger on the core file, like ` curl + core`. `` should be replaced with the name of your debugger, in + most cases that will be `gdb`, but `dbx` and others also occur. + + When the debugger has finished loading the core file and presents you a + prompt, enter `where` (without quotes) and press return. + + The list that is presented is the stack trace. If everything worked, it is + supposed to contain the chain of functions that were called when curl + crashed. Include the stack trace with your detailed bug report, it will help a + lot. + +## Bugs in libcurl bindings + + There will of course pop up bugs in libcurl bindings. You should then + primarily approach the team that works on that particular binding and see + what you can do to help them fix the problem. + + If you suspect that the problem exists in the underlying libcurl, then please + convert your program over to plain C and follow the steps outlined above. + +## Bugs in old versions + + The curl project typically releases new versions every other month, and we + fix several hundred bugs per year. For a huge table of releases, number of + bug fixes and more, see: https://curl.se/docs/releases.html + + The developers in the curl project do not have bandwidth or energy enough to + maintain several branches or to spend much time on hunting down problems in + old versions when chances are we already fixed them or at least that they have + changed nature and appearance in later versions. + + When you experience a problem and want to report it, you really SHOULD + include the version number of the curl you are using when you experience the + issue. If that version number shows us that you are using an out-of-date curl, + you should also try out a modern curl version to see if the problem persists + or how/if it has changed in appearance. + + Even if you cannot immediately upgrade your application/system to run the + latest curl version, you can most often at least run a test version or + experimental build or similar, to get this confirmed or not. + + At times people insist that they cannot upgrade to a modern curl version, but + instead, they "just want the bug fixed". That is fine, just do not count on us + spending many cycles on trying to identify which single commit, if that is + even possible, that at some point in the past fixed the problem you are now + experiencing. + + Security wise, it is almost always a bad idea to lag behind the current curl + versions by a lot. We keep discovering and reporting security problems + over time see you can see in [this + table](https://curl.se/docs/vulnerabilities.html) + +# Bug fixing procedure + +## What happens on first filing + + When a new issue is posted in the issue tracker or on the mailing list, the + team of developers first needs to see the report. Maybe they took the day off, + maybe they are off in the woods hunting. Have patience. Allow at least a few + days before expecting someone to have responded. + + In the issue tracker, you can expect that some labels will be set on the issue + to help categorize it. + +## First response + + If your issue/bug report was not perfect at once (and few are), chances are + that someone will ask follow-up questions. Which version did you use? Which + options did you use? How often does the problem occur? How can we reproduce + this problem? Which protocols does it involve? Or perhaps much more specific + and deep diving questions. It all depends on your specific issue. + + You should then respond to these follow-up questions and provide more info + about the problem, so that we can help you figure it out. Or maybe you can + help us figure it out. An active back-and-forth communication is important + and the key for finding a cure and landing a fix. + +## Not reproducible + + We may require further work from you who actually see or experience the + problem if we cannot reproduce it and cannot understand it even after having + gotten all the info we need and having studied the source code over again. + +## Unresponsive + + If the problem have not been understood or reproduced, and there is nobody + responding to follow-up questions or questions asking for clarifications or + for discussing possible ways to move forward with the task, we take that as a + strong suggestion that the bug is unimportant. + + Unimportant issues will be closed as inactive sooner or later as they cannot + be fixed. The inactivity period (waiting for responses) should not be shorter + than two weeks but may extend months. + +## Lack of time/interest + + Bugs that are filed and are understood can unfortunately end up in the + "nobody cares enough about it to work on it" category. Such bugs are + perfectly valid problems that *should* get fixed but apparently are not.

You are always encouraged and free to grab one of those items and + take up a discussion with the curl development team on how that could be + implemented or provided in the project so that you can work on ticking it odd + that document. + + If an issue is rather a bug and not a missing feature or functionality, it is + listed in `KNOWN_BUGS` instead. + +## Closing off stalled bugs + + The [issue and pull request trackers](https://github.com/curl/curl) only + hold "active" entries open (using a non-precise definition of what active + actually is, but they are at least not completely dead). Those that are + abandoned or in other ways dormant will be closed and sometimes added to + `TODO` and `KNOWN_BUGS` instead. + + This way, we only have "active" issues open on GitHub.

The functions sprintf, vsprintf, + strcat, strncat, gets are **never** allowed in curl source code. + +- `BRACEELSE`: '} else' on the same line.

To enable these warnings, place a `.checksrc` file in +the directory where they should be activated with commands to enable the +warnings you are interested in. The format of the file is to enable one +warning per line like so: `enable ` + +Currently these are the extended warnings which can be enabled: + +- `COPYRIGHTYEAR`: the current changeset has not updated the copyright year in + the source file + +- `STRERROR`: use of banned function strerror() + +- `STDERR`: use of banned variable `stderr` + +## Ignore certain warnings + +Due to the nature of the source code and the flaws of the `checksrc` tool, +there is sometimes a need to ignore specific warnings. `checksrc` allows a few +different ways to do this. + +### Inline ignore + +You can control what to ignore within a specific source file by providing +instructions to `checksrc` in the source code itself. See examples below. The +instruction can ask to ignore a specific warning a specific number of times or +you ignore all of them until you mark the end of the ignored section. + +Inline ignores are only done for that single specific source code file. + +Example + + /* !checksrc! disable LONGLINE all */ + +This will ignore the warning for overly long lines until it is re-enabled with: + + /* !checksrc! enable LONGLINE */ + +If the enabling is not performed before the end of the file, it will be enabled +automatically for the next file. + +You can also opt to ignore just N violations so that if you have a single long +line you just cannot shorten and is agreed to be fine anyway: + + /* !checksrc! disable LONGLINE 1 */ + +... and the warning for long lines will be enabled again automatically after +it has ignored that single warning. The number `1` can of course be changed to +any other integer number. It can be used to make sure only the exact intended +instances are ignored and nothing extra. + +### Directory wide ignore patterns + +This is a method we have transitioned away from. Use inline ignores as far as +possible. + +Make a `checksrc.skip` file in the directory of the source code with the +false positive, and include the full offending line into this file. diff --git a/src/ext/curl/docs/CIPHERS.md b/src/ext/curl/docs/CIPHERS.md new file mode 100644 index 00000000..f616f497 --- /dev/null +++ b/src/ext/curl/docs/CIPHERS.md @@ -0,0 +1,427 @@ +# Ciphers + +With curl's options +[`CURLOPT_SSL_CIPHER_LIST`](https://curl.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html) +and +[`--ciphers`](https://curl.se/docs/manpage.html#--ciphers) +users can control which ciphers to consider when negotiating TLS connections. + +TLS 1.3 ciphers are supported since curl 7.61 for OpenSSL 1.1.1+, and since +curl 7.85 for Schannel with options +[`CURLOPT_TLS13_CIPHERS`](https://curl.se/libcurl/c/CURLOPT_TLS13_CIPHERS.html) +and +[`--tls13-ciphers`](https://curl.se/docs/manpage.html#--tls13-ciphers) +.

Applications register callbacks via `CURLOPT_WRITEFUNCTION` and `CURLOPT_HEADERFUNCTION` to be invoked by `libcurl` when the response is received. + +## Invoking + +All code in `libcurl` that handles response data is ultimately expected to forward this data via `Curl_client_write()` to the application. The exact prototype of this function is: + +``` +CURLcode Curl_client_write(struct Curl_easy *data, int type, char *buf, size_t blen); +``` +The `type` argument specifies what the bytes in `buf` actually are. The following bits are defined: + +``` +#define CLIENTWRITE_BODY (1<<0) /* non-meta information, BODY */ +#define CLIENTWRITE_INFO (1<<1) /* meta information, not a HEADER */ +#define CLIENTWRITE_HEADER (1<<2) /* meta information, HEADER */ +#define CLIENTWRITE_STATUS (1<<3) /* a special status HEADER */ +#define CLIENTWRITE_CONNECT (1<<4) /* a CONNECT related HEADER */ +#define CLIENTWRITE_1XX (1<<5) /* a 1xx response related HEADER */ +#define CLIENTWRITE_TRAILER (1<<6) /* a trailer HEADER */ +``` + +The main types here are `CLIENTWRITE_BODY` and `CLIENTWRITE_HEADER`. They are +mutually exclusive. The other bits are enhancements to `CLIENTWRITE_HEADER` to +specify what the header is about. They are only used in HTTP and related +protocols (RTSP and WebSocket). + +The implementation of `Curl_client_write()` uses a chain of *client writer* instances to process the call and make sure that the bytes reach the proper application callbacks. This is similar to the design of connection filters: client writers can be chained to process the bytes written through them. The definition is: + +``` +struct Curl_cwtype { + const char *name; + CURLcode (*do_init)(struct Curl_easy *data, + struct Curl_cwriter *writer); + CURLcode (*do_write)(struct Curl_easy *data, + struct Curl_cwriter *writer, int type, + const char *buf, size_t nbytes); + void (*do_close)(struct Curl_easy *data, + struct Curl_cwriter *writer); +}; + +struct Curl_cwriter { + const struct Curl_cwtype *cwt; /* type implementation */ + struct Curl_cwriter *next; /* Downstream writer. */ + Curl_cwriter_phase phase; /* phase at which it operates */ +}; +``` + +`Curl_cwriter` is a writer instance with a `next` pointer to form the chain. It has a type `cwt` which provides the implementation. The main callback is `do_write()` that processes the data and calls then the `next` writer. The others are for setup and tear down. + +## Phases and Ordering + +Since client writers may transform the bytes written through them, the order in which the are called is relevant for the outcome. When a writer is created, one property it gets is the `phase` in which it operates. Writer phases are defined like: + +``` +typedef enum { + CURL_CW_RAW, /* raw data written, before any decoding */ + CURL_CW_TRANSFER_DECODE, /* remove transfer-encodings */ + CURL_CW_PROTOCOL, /* after transfer, but before content decoding */ + CURL_CW_CONTENT_DECODE, /* remove content-encodings */ + CURL_CW_CLIENT /* data written to client */ +} Curl_cwriter_phase; +``` + +If a writer for phase `PROTOCOL` is added to the chain, it is always added *after* any `RAW` or `TRANSFER_DECODE` and *before* any `CONTENT_DECODE` and `CLIENT` phase writer. If there is already a writer for the same phase present, the new writer is inserted just before that one. + +All transfers have a chain of 3 writers by default. A specific protocol handler may alter that by adding additional writers. The 3 standard writers are (name, phase): + +1. `"raw", CURL_CW_RAW `: if the transfer is verbose, it forwards the body data to the debug function. +1. `"download", CURL_CW_PROTOCOL`: checks that protocol limits are kept and updates progress counters. When a download has a known length, it checks that it is not exceeded and errors otherwise. +1. `"client", CURL_CW_CLIENT`: the main work horse. It invokes the application callbacks or writes to the configured file handles. It chops large writes into smaller parts, as documented for `CURLOPT_WRITEFUNCTION`. If also handles *pausing* of transfers when the application callback returns `CURL_WRITEFUNC_PAUSE`. + +With these writers always in place, libcurl's protocol handlers automatically have these implemented. + +## Enhanced Use + +HTTP is the protocol in curl that makes use of the client writer chain by adding writers to it. When the `libcurl` application set `CURLOPT_ACCEPT_ENCODING` (as `curl` does with `--compressed`), the server is offered an `Accept-Encoding` header with the algorithms supported. The server then may choose to send the response body compressed. For example using `gzip` or `brotli` or even both. + +In the server's response, there then will be a `Content-Encoding` header listing the encoding applied. If supported by `libcurl` it will then decompress the content before writing it out to the client. How does it do that? + +The HTTP protocol will add client writers in phase `CURL_CW_CONTENT_DECODE` on seeing such a header. For each encoding listed, it will add the corresponding writer. The response from the server is then passed through `Curl_client_write()` to the writers that decode it. If several encodings had been applied the writer chain decodes them in the proper order. + +When the server provides a `Content-Length` header, that value applies to the *compressed* content. So length checks on the response bytes must happen *before* it gets decoded. That is why this check happens in phase `CURL_CW_PROTOCOL` which always is ordered before writers in phase `CURL_CW_CONTENT_DECODE`. + +What else? + +Well, HTTP servers may also apply a `Transfer-Encoding` to the body of a response. The most well-known one is `chunked`, but algorithms like `gzip` and friends could also be applied. The difference to content encodings is that decoding needs to happen *before* protocol checks, for example on length, are done. + +That is why transfer decoding writers are added for phase `CURL_CW_TRANSFER_DECODE`. Which makes their operation happen *before* phase `CURL_CW_PROTOCOL` where length may be checked. + +## Summary + +By adding the common behavior of all protocols into `Curl_client_write()` we make sure that they do apply everywhere. Protocol handler have less to worry about. Changes to default behavior can be done without affecting handler implementations. + +Having a writer chain as implementation allows protocol handlers with extra needs, like HTTP, to add to this for special behavior. The common way of writing the actual response data stays the same. + diff --git a/src/ext/curl/docs/CMakeLists.txt b/src/ext/curl/docs/CMakeLists.txt new file mode 100644 index 00000000..9c0b3769 --- /dev/null +++ b/src/ext/curl/docs/CMakeLists.txt @@ -0,0 +1,30 @@ +#*************************************************************************** +# _ _ ____ _ +# Project ___| | | | _ \| | +# / __| | | | |_) | | +# | (__| |_| | _ <| |___ +# \___|\___/|_| \_\_____| +# +# Copyright (C) Daniel Stenberg, , et al. +# +# This software is licensed as described in the file COPYING, which +# you should have received as part of this distribution.

They were added in curl v7.87.0. This document describes the +concepts, its high level implementation and the motivations. + +## Filters + +A "connection filter" is a piece of code that is responsible for handling a +range of operations of curl's connections: reading, writing, waiting on +external events, connecting and closing down - to name the most important +ones. + +The most important feat of connection filters is that they can be stacked on +top of each other (or "chained" if you prefer that metaphor). In the common +scenario that you want to retrieve a `https:` URL with curl, you need 2 basic +things to send the request and get the response: a TCP connection, represented +by a `socket` and a SSL instance en- and decrypt over that socket. You write +your request to the SSL instance, which encrypts and writes that data to the +socket, which then sends the bytes over the network. + +With connection filters, curl's internal setup will look something like this +(cf for connection filter): + +``` +Curl_easy *data connectdata *conn cf-ssl cf-socket ++----------------+ +-----------------+ +-------+ +--------+ +|https://curl.se/|----> | properties |----> | keys |---> | socket |--> OS --> network ++----------------+ +-----------------+ +-------+ +--------+ + + Curl_write(data, buffer) + --> Curl_cfilter_write(data, data->conn, buffer) + ---> conn->filter->write(conn->filter, data, buffer) +``` + +While connection filters all do different things, they look the same from the "outside". The code in `data` and `conn` does not really know **which** filters are installed. `conn` just writes into the first filter, whatever that is. + +Same is true for filters. Each filter has a pointer to the `next` filter. When SSL has encrypted the data, it does not write to a socket, it writes to the next filter. If that is indeed a socket, or a file, or an HTTP/2 connection is of no concern to the SSL filter. + +This allows stacking, as in: + +``` +Direct: + http://localhost/ conn -> cf-socket + https://curl.se/ conn -> cf-ssl -> cf-socket +Via http proxy tunnel: + http://localhost/ conn -> cf-http-proxy -> cf-socket + https://curl.se/ conn -> cf-ssl -> cf-http-proxy -> cf-socket +Via https proxy tunnel: + http://localhost/ conn -> cf-http-proxy -> cf-ssl -> cf-socket + https://curl.se/ conn -> cf-ssl -> cf-http-proxy -> cf-ssl -> cf-socket +Via http proxy tunnel via SOCKS proxy: + http://localhost/ conn -> cf-http-proxy -> cf-socks -> cf-socket +``` + +### Connecting/Closing + +Before `Curl_easy` can send the request, the connection needs to be established. This means that all connection filters have done, whatever they need to do: waiting for the socket to be connected, doing the TLS handshake, performing the HTTP tunnel request, etc. This has to be done in reverse order: the last filter has to do its connect first, then the one above can start, etc. + +Each filter does in principle the following: + +``` +static CURLcode +myfilter_cf_connect(struct Curl_cfilter *cf, + struct Curl_easy *data, + bool *done) +{ + CURLcode result; + + if(cf->connected) { /* we and all below are done */ + *done = TRUE; + return CURLE_OK; + } + /* Let the filters below connect */ + result = cf->next->cft->connect(cf->next, data, blocking, done); + if(result || !*done) + return result; /* below errored/not finished yet */ + + /* MYFILTER CONNECT THINGS */ /* below connected, do out thing */ + *done = cf->connected = TRUE; /* done, remember, return */ + return CURLE_OK; +} +``` + +Closing a connection then works similar. The `conn` tells the first filter to close. Contrary to connecting, +the filter does its own things first, before telling the next filter to close. + +### Efficiency + +There are two things curl is concerned about: efficient memory use and fast transfers. + +The memory footprint of a filter is relatively small: + +``` +struct Curl_cfilter { + const struct Curl_cftype *cft; /* the type providing implementation */ + struct Curl_cfilter *next; /* next filter in chain */ + void *ctx; /* filter type specific settings */ + struct connectdata *conn; /* the connection this filter belongs to */ + int sockindex; /* TODO: like to get rid off this */ + BIT(connected); /* != 0 iff this filter is connected */ +}; +``` +The filter type `cft` is a singleton, one static struct for each type of filter. The `ctx` is where a filter will hold its specific data. That varies by filter type. An http-proxy filter will keep the ongoing state of the CONNECT here, but free it after its has been established. The SSL filter will keep the `SSL*` (if OpenSSL is used) here until the connection is closed. So, this varies. + +`conn` is a reference to the connection this filter belongs to, so nothing extra besides the pointer itself. + +Several things, that before were kept in `struct connectdata`, will now go into the `filter->ctx` *when needed*. So, the memory footprint for connections that do *not* use an http proxy, or socks, or https will be lower. + +As to transfer efficiency, writing and reading through a filter comes at near zero cost *if the filter does not transform the data*. An http proxy or socks filter, once it is connected, will just pass the calls through. Those filters implementations will look like this: + +``` +ssize_t Curl_cf_def_send(struct Curl_cfilter *cf, struct Curl_easy *data, + const void *buf, size_t len, CURLcode *err) +{ + return cf->next->cft->do_send(cf->next, data, buf, len, err); +} +``` +The `recv` implementation is equivalent. + +## Filter Types + +The currently existing filter types (curl 8.5.0) are: + +* `TCP`, `UDP`, `UNIX`: filters that operate on a socket, providing raw I/O. +* `SOCKET-ACCEPT`: special TCP socket that has a socket that has been `accept()`ed in a `listen()` +* `SSL`: filter that applies TLS en-/decryption and handshake. Manages the underlying TLS backend implementation. +* `HTTP-PROXY`, `H1-PROXY`, `H2-PROXY`: the first manages the connection to an + HTTP proxy server and uses the other depending on which ALPN protocol has + been negotiated. +* `SOCKS-PROXY`: filter for the various SOCKS proxy protocol variations +* `HAPROXY`: filter for the protocol of the same name, providing client IP information to a server. +* `HTTP/2`: filter for handling multiplexed transfers over an HTTP/2 connection +* `HTTP/3`: filter for handling multiplexed transfers over an HTTP/3+QUIC connection +* `HAPPY-EYEBALLS`: meta filter that implements IPv4/IPv6 "happy eyeballing". It creates up to 2 sub-filters that race each other for a connection. +* `SETUP`: meta filter that manages the creation of sub-filter chains for a specific transport (e.g. TCP or QUIC). +* `HTTPS-CONNECT`: meta filter that races a TCP+TLS and a QUIC connection against each other to determine if HTTP/1.1, HTTP/2 or HTTP/3 shall be used for a transfer. + +Meta filters are combining other filters for a specific purpose, mostly during connection establishment. Other filters like `TCP`, `UDP` and `UNIX` are only to be found at the end of filter chains. SSL filters provide encryption, of course. Protocol filters change the bytes sent and received. + +## Filter Flags + +Filter types carry flags that inform what they do. These are (for now): + +* `CF_TYPE_IP_CONNECT`: this filter type talks directly to a server. This does not have to be the server the transfer wants to talk to. For example when a proxy server is used. +* `CF_TYPE_SSL`: this filter type provides encryption. +* `CF_TYPE_MULTIPLEX`: this filter type can manage multiple transfers in parallel. + +Filter types can combine these flags. For example, the HTTP/3 filter types have `CF_TYPE_IP_CONNECT`, `CF_TYPE_SSL` and `CF_TYPE_MULTIPLEX` set. + +Flags are useful to extrapolate properties of a connection. To check if a connection is encrypted, libcurl inspect the filter chain in place, top down, for `CF_TYPE_SSL`. If it finds `CF_TYPE_IP_CONNECT` before any `CF_TYPE_SSL`, the connection is not encrypted. + +For example, `conn1` is for a `http:` request using a tunnel through a HTTP/2 `https:` proxy. `conn2` is a `https:` HTTP/2 connection to the same proxy. `conn3` uses HTTP/3 without proxy. The filter chains would look like this (simplified): + +``` +conn1 --> `HTTP-PROXY` --> `H2-PROXY` --> `SSL` --> `TCP` +flags: `IP_CONNECT` `SSL` `IP_CONNECT` + +conn2 --> `HTTP/2` --> `SSL` --> `HTTP-PROXY` --> `H2-PROXY` --> `SSL` --> `TCP` +flags: `SSL` `IP_CONNECT` `SSL` `IP_CONNECT` + +conn3 --> `HTTP/3` +flags: `SSL|IP_CONNECT` +``` + +Inspecting the filter chains, `conn1` is seen as unencrypted, since it contains an `IP_CONNECT` filter before any `SSL`. `conn2` is clearly encrypted as an `SSL` flagged filter is seen first. `conn3` is also encrypted as the `SSL` flag is checked before the presence of `IP_CONNECT`. + +Similar checks can determine if a connection is multiplexed or not. + +## Filter Tracing + +Filters may make use of special trace macros like `CURL_TRC_CF(data, cf, msg, ...)`. With `data` being the transfer and `cf` being the filter instance. These traces are normally not active and their execution is guarded so that they are cheap to ignore. + +Users of `curl` may activate them by adding the name of the filter type to the +`--trace-config` argument. For example, in order to get more detailed tracing +of an HTTP/2 request, invoke curl with: + +``` +> curl -v --trace-config ids,time,http/2 https://curl.se +``` +Which will give you trace output with time information, transfer+connection ids and details from the `HTTP/2` filter. Filter type names in the trace config are case insensitive. You may use `all` to enable tracing for all filter types. When using `libcurl` you may call `curl_global_trace(config_string)` at the start of your application to enable filter details. + +## Meta Filters + +Meta filters is a catch-all name for filter types that do not change the transfer data in any way but provide other important services to curl. In general, it is possible to do all sorts of silly things with them. One of the commonly used, important things is "eyeballing". + +The `HAPPY-EYEBALLS` filter is involved in the connect phase. Its job is to +try the various IPv4 and IPv6 addresses that are known for a server. If only +one address family is known (or configured), it tries the addresses one after +the other with timeouts calculated from the amount of addresses and the +overall connect timeout. + +When more than one address family is to be tried, it splits the address list into IPv4 and IPv6 and makes parallel attempts. The connection filter chain will look like this: + +``` +* create connection for http://curl.se +conn[curl.se] --> SETUP[TCP] --> HAPPY-EYEBALLS --> NULL +* start connect +conn[curl.se] --> SETUP[TCP] --> HAPPY-EYEBALLS --> NULL + - ballerv4 --> TCP[151.101.1.91]:443 + - ballerv6 --> TCP[2a04:4e42:c00::347]:443 +* v6 answers, connected +conn[curl.se] --> SETUP[TCP] --> HAPPY-EYEBALLS --> TCP[2a04:4e42:c00::347]:443 +* transfer +``` + +The modular design of connection filters and that we can plug them into each other is used to control the parallel attempts. When a `TCP` filter does not connect (in time), it is torn down and another one is created for the next address. This keeps the `TCP` filter simple. + +The `HAPPY-EYEBALLS` on the other hand stays focused on its side of the problem. We can use it also to make other type of connection by just giving it another filter type to try and have happy eyeballing for QUIC: + +``` +* create connection for --http3-only https://curl.se +conn[curl.se] --> SETUP[QUIC] --> HAPPY-EYEBALLS --> NULL +* start connect +conn[curl.se] --> SETUP[QUIC] --> HAPPY-EYEBALLS --> NULL + - ballerv4 --> HTTP/3[151.101.1.91]:443 + - ballerv6 --> HTTP/3[2a04:4e42:c00::347]:443 +* v6 answers, connected +conn[curl.se] --> SETUP[QUIC] --> HAPPY-EYEBALLS --> HTTP/3[2a04:4e42:c00::347]:443 +* transfer +``` + +When we plug these two variants together, we get the `HTTPS-CONNECT` filter +type that is used for `--http3` when **both** HTTP/3 and HTTP/2 or HTTP/1.1 +shall be attempted: + +``` +* create connection for --http3 https://curl.se +conn[curl.se] --> HTTPS-CONNECT --> NULL +* start connect +conn[curl.se] --> HTTPS-CONNECT --> NULL + - SETUP[QUIC] --> HAPPY-EYEBALLS --> NULL + - ballerv4 --> HTTP/3[151.101.1.91]:443 + - ballerv6 --> HTTP/3[2a04:4e42:c00::347]:443 + - SETUP[TCP] --> HAPPY-EYEBALLS --> NULL + - ballerv4 --> TCP[151.101.1.91]:443 + - ballerv6 --> TCP[2a04:4e42:c00::347]:443 +* v4 QUIC answers, connected +conn[curl.se] --> HTTPS-CONNECT --> SETUP[QUIC] --> HAPPY-EYEBALLS --> HTTP/3[151.101.1.91]:443 +* transfer +``` + diff --git a/src/ext/curl/docs/CONTRIBUTE.md b/src/ext/curl/docs/CONTRIBUTE.md new file mode 100644 index 00000000..29d98cf1 --- /dev/null +++ b/src/ext/curl/docs/CONTRIBUTE.md @@ -0,0 +1,316 @@ +# Contributing to the curl project + +This document is intended to offer guidelines on how to best contribute to the +curl project. This concerns new features as well as corrections to existing +flaws or bugs. + +## Join the Community + +Skip over to [https://curl.se/mail/](https://curl.se/mail/) and join +the appropriate mailing list(s). Read up on details before you post +questions. Read this file before you start sending patches. We prefer +questions sent to and discussions being held on the mailing list(s), not sent +to individuals. + +Before posting to one of the curl mailing lists, please read up on the +[mailing list etiquette](https://curl.se/mail/etiquette.html). + +We also hang out on IRC in #curl on libera.chat + +If you are at all interested in the code side of things, consider clicking +'watch' on the [curl repo on GitHub](https://github.com/curl/curl) to be +notified of pull requests and new issues posted there. + +## License and copyright + +When contributing with code, you agree to put your changes and new code under +the same license curl and libcurl is already using unless stated and agreed +otherwise. + +If you add a larger piece of code, you can opt to make that file or set of +files to use a different license as long as they do not enforce any changes to +the rest of the package and they make sense. Such "separate parts" can not be +GPL licensed (as we do not want copyleft to affect users of libcurl) but they +must use "GPL compatible" licenses (as we want to allow users to use libcurl +properly in GPL licensed environments). + +When changing existing source code, you do not alter the copyright of the +original file(s). The copyright will still be owned by the original creator(s) +or those who have been assigned copyright by the original author(s). + +By submitting a patch to the curl project, you are assumed to have the right +to the code and to be allowed by your employer or whatever to hand over that +patch/code to us. We will credit you for your changes as far as possible, to +give credit but also to keep a trace back to who made what changes. Please +always provide us with your full real name when contributing, + +## What To Read + +Source code, the man pages, the [INTERNALS +document](https://curl.se/dev/internals.html), +[TODO](https://curl.se/docs/todo.html), +[KNOWN_BUGS](https://curl.se/docs/knownbugs.html) and the [most recent +changes](https://curl.se/dev/sourceactivity.html) in git. Just lurking on +the [curl-library mailing +list](https://curl.se/mail/list.cgi?list=curl-library) will give you a +lot of insights on what's going on right now. Asking there is a good idea too. + +## Write a good patch + +### Follow code style + +When writing C code, follow the +[CODE_STYLE](https://curl.se/dev/code-style.html) already established in +the project. Consistent style makes code easier to read and mistakes less +likely to happen. Run `make checksrc` before you submit anything, to make sure +you follow the basic style. That script does not verify everything, but if it +complains you know you have work to do. + +### Non-clobbering All Over + +When you write new functionality or fix bugs, it is important that you do not +fiddle all over the source files and functions. Remember that it is likely +that other people have done changes in the same source files as you have and +possibly even in the same functions. If you bring completely new +functionality, try writing it in a new source file. If you fix bugs, try to +fix one bug at a time and send them as separate patches. + +### Write Separate Changes + +It is annoying when you get a huge patch from someone that is said to fix 511 +odd problems, but discussions and opinions do not agree with 510 of them - or +509 of them were already fixed in a different way. Then the person merging +this change needs to extract the single interesting patch from somewhere +within the huge pile of source, and that creates a lot of extra work. + +Preferably, each fix that corrects a problem should be in its own patch/commit +with its own description/commit message stating exactly what they correct so +that all changes can be selectively applied by the maintainer or other +interested parties. + +Also, separate changes enable bisecting much better for tracking problems +and regression in the future. + +### Patch Against Recent Sources + +Please try to get the latest available sources to make your patches against. +It makes the lives of the developers so much easier. The best is if you get +the most up-to-date sources from the git repository, but the latest release +archive is quite OK as well. + +### Documentation + +Writing docs is dead boring and one of the big problems with many open source +projects but someone's gotta do it. It makes things a lot easier if you submit +a small description of your fix or your new features with every contribution +so that it can be swiftly added to the package documentation. + +The documentation is always made in man pages (nroff formatted) or plain +ASCII files. All HTML files on the website and in the release archives are +generated from the nroff/ASCII versions. + +### Test Cases + +Since the introduction of the test suite, we can quickly verify that the main +features are working as they are supposed to. To maintain this situation and +improve it, all new features and functions that are added need to be tested +in the test suite. Every feature that is added should get at least one valid +test case that verifies that it works as documented. If every submitter also +posts a few test cases, it will not end up as a heavy burden on a single person. + +If you do not have test cases or perhaps you have done something that is hard +to write tests for, do explain exactly how you have otherwise tested and +verified your changes. + +## Submit Your Changes + +### How to get your changes into the main sources + +Ideally you file a [pull request on +GitHub](https://github.com/curl/curl/pulls), but you can also send your plain +patch to [the curl-library mailing +list](https://curl.se/mail/list.cgi?list=curl-library). + +If you opt to post a patch on the mailing list, chances are someone will +convert it into a pull request for you, to have the CI jobs verify it proper +before it can be merged. Be prepared that some feedback on the proposed change +might then come on GitHub. + +Your change will be reviewed and discussed and you will be expected to correct +flaws pointed out and update accordingly, or the change risks stalling and +eventually just getting deleted without action. As a submitter of a change, +you are the owner of that change until it has been merged. + +Respond on the list or on GitHub about the change and answer questions and/or +fix nits/flaws. This is important. We will take lack of replies as a sign that +you are not anxious to get your patch accepted and we tend to simply drop such +changes. + +### About pull requests + +With GitHub it is easy to send a [pull +request](https://github.com/curl/curl/pulls) to the curl project to have +changes merged. + +We strongly prefer pull requests to mailed patches, as it makes it a proper +git commit that is easy to merge and they are easy to track and not that easy +to lose in the flood of many emails, like they sometimes do on the mailing +lists. + +Every pull request submitted will automatically be tested in several different +ways. [See the CI document for more +information](https://github.com/curl/curl/blob/master/tests/CI.md). + +Sometimes the tests fail due to a dependency service temporarily being offline +or otherwise unavailable, e.g. package downloads. In this case you can just +try to update your pull requests to rerun the tests later as described below. + +You can update your pull requests by pushing new commits or force-pushing +changes to existing commits. Force-pushing an amended commit without any +actual content changed also allows you to retrigger the tests for that commit. + +When you adjust your pull requests after review, consider squashing the +commits so that we can review the full updated version more easily. + +A pull request sent to the project might get labeled `needs-votes` by a +project maintainer. This label means that in addition to meeting all other +checks and qualifications this pull request must also receive more "votes" of +user support. More signs that people want this to happen. It could be in the +form of messages saying so, or thumbs-up reactions on GitHub. + +### Making quality changes + +Make the patch against as recent source versions as possible. + +If you have followed the tips in this document and your patch still has not +been incorporated or responded to after some weeks, consider resubmitting it +to the list or better yet: change it to a pull request. + +### Commit messages + +A short guide to how to write git commit messages in the curl project. + + ---- start ---- + [area]: [short line describing the main effect] + -- empty line -- + [full description, no wider than 72 columns that describes as much as + possible as to why this change is made, and possibly what things + it fixes and everything else that is related, with unwieldy URLs replaced + with references like [0], [1], etc.] + -- empty line -- + [[0] URL - Reference to a URL in the description, almost like Markdown; + the last numbered reference is followed by an -- empty line -- ] + [Follow-up to {shorthash} - if this fixes or continues a previous commit; + add a Ref: that commit's PR or issue if it's not a small, obvious fix; + followed by an -- empty line -- ] + [Bug: URL to the source of the report or more related discussion; use Fixes + for GitHub issues instead when that is appropriate] + [Approved-by: John Doe - credit someone who approved the PR; if you are + committing this for someone else using --author=... you do not need this + as you are implicitly approving it by committing] + [Authored-by: John Doe - credit the original author of the code; only use + this if you cannot use "git commit --author=..."] + [Signed-off-by: John Doe - we do not use this, but do not bother removing it] + [whatever-else-by: credit all helpers, finders, doers; try to use one of + the following keywords if at all possible, for consistency: + Acked-by:, Assisted-by:, Co-authored-by:, Found-by:, Reported-by:, + Reviewed-by:, Suggested-by:, Tested-by:] + [Ref: #1234 - if this is related to a GitHub issue or PR, possibly one that + has already been closed] + [Ref: URL to more information about the commit; use Bug: instead for + a reference to a bug on another bug tracker] + [Fixes #1234 - if this closes a GitHub issue; GitHub will actually + close the issue once this commit is merged] + [Closes #1234 - if this closes a GitHub PR; GitHub will actually + close the PR once this commit is merged] + ---- stop ---- + +The first line is a succinct description of the change: + + - use the imperative, present tense: "change" not "changed" nor "changes" + - do not capitalize the first letter + - no period (.) at the end + +The `[area]` in the first line can be `http2`, `cookies`, `openssl` or +similar. There is no fixed list to select from but using the same "area" as +other related changes could make sense. + +Do not forget to use commit --author=... if you commit someone else's work, and +make sure that you have your own user and email setup correctly in git before +you commit. + +Add whichever header lines as appropriate, with one line per person if more +than one person was involved. There is no need to credit yourself unless you +are using --author=... which hides your identity. Do not include people's +email addresses in headers to avoid spam, unless they are already public from +a previous commit; saying `{userid} on github` is OK. + +### Write Access to git Repository + +If you are a frequent contributor, you may be given push access to the git +repository and then you will be able to push your changes straight into the git +repo instead of sending changes as pull requests or by mail as patches. + +Just ask if this is what you would want. You will be required to have posted +several high quality patches first, before you can be granted push access. + +### How To Make a Patch with git + +You need to first checkout the repository: + + git clone https://github.com/curl/curl.git + +You then proceed and edit all the files you like and you commit them to your +local repository: + + git commit [file] + +As usual, group your commits so that you commit all changes at once that +constitute a logical change. + +Once you have done all your commits and you are happy with what you see, you +can make patches out of your changes that are suitable for mailing: + + git format-patch remotes/origin/master + +This creates files in your local directory named `NNNN-[name].patch` for each +commit. + +Now send those patches off to the curl-library list. You can of course opt to +do that with the 'git send-email' command. + +### How To Make a Patch without git + +Keep a copy of the unmodified curl sources. Make your changes in a separate +source tree. When you think you have something that you want to offer the +curl community, use GNU diff to generate patches. + +If you have modified a single file, try something like: + + diff -u unmodified-file.c my-changed-one.c > my-fixes.diff + +If you have modified several files, possibly in different directories, you +can use diff recursively: + + diff -ur curl-original-dir curl-modified-sources-dir > my-fixes.diff + +The GNU diff and GNU patch tools exist for virtually all platforms, including +all kinds of Unixes and Windows. + +### Useful resources + - [Webinar on getting code into cURL](https://www.youtube.com/watch?v=QmZ3W1d6LQI) + +## Update copyright and license information + +There is a CI job called **REUSE compliance / check** that will run on every +pull request and commit to verify that the *REUSE state* of all files are +still fine. + +This means that all files need to have their license and copyright information +clearly stated. Ideally by having the standard curl source code header, with +the SPDX-License-Identifier included. If the header does not work, you can use a +smaller header or add the information for a specific file to the `.reuse/dep5` +file. + +You can manually verify the copyright and compliance status by running the +`./scripts/copyright.pl` script in the root of the git repository. diff --git a/src/ext/curl/docs/CURL-DISABLE.md b/src/ext/curl/docs/CURL-DISABLE.md new file mode 100644 index 00000000..7978ed21 --- /dev/null +++ b/src/ext/curl/docs/CURL-DISABLE.md @@ -0,0 +1,168 @@ +# Code defines to disable features and protocols + +## `CURL_DISABLE_ALTSVC` + +Disable support for Alt-Svc: HTTP headers. + +## `CURL_DISABLE_BINDLOCAL` + +Disable support for binding the local end of connections. + +## `CURL_DISABLE_COOKIES` + +Disable support for HTTP cookies. + +## `CURL_DISABLE_BASIC_AUTH` + +Disable support for the Basic authentication methods. + +## `CURL_DISABLE_BEARER_AUTH` + +Disable support for the Bearer authentication methods. + +## `CURL_DISABLE_DIGEST_AUTH` + +Disable support for the Digest authentication methods. + +## `CURL_DISABLE_KERBEROS_AUTH` + +Disable support for the Kerberos authentication methods. + +## `CURL_DISABLE_NEGOTIATE_AUTH` + +Disable support for the negotiate authentication methods. + +## `CURL_DISABLE_AWS` + +Disable **AWS-SIG4** support. + +## `CURL_DISABLE_DICT` + +Disable the DICT protocol + +## `CURL_DISABLE_DOH` + +Disable DNS-over-HTTPS + +## `CURL_DISABLE_FILE` + +Disable the FILE protocol + +## `CURL_DISABLE_FORM_API` + +Disable the form API + +## `CURL_DISABLE_FTP` + +Disable the FTP (and FTPS) protocol + +## `CURL_DISABLE_GETOPTIONS` + +Disable the `curl_easy_options` API calls that lets users get information +about existing options to `curl_easy_setopt`. + +## `CURL_DISABLE_GOPHER` + +Disable the GOPHER protocol. + +## `CURL_DISABLE_HEADERS_API` + +Disable the HTTP header API. + +## `CURL_DISABLE_HSTS` + +Disable the HTTP Strict Transport Security support. + +## `CURL_DISABLE_HTTP` + +Disable the HTTP(S) protocols.

Development + 8.1 Why does curl use C89? + 8.2 Will curl be rewritten? + +============================================================================== + +1. Philosophy + + 1.1 What is cURL? + + cURL is the name of the project. The name is a play on 'Client for URLs', + originally with URL spelled in uppercase to make it obvious it deals with + URLs. The fact it can also be read as 'see URL' also helped, it works as + an abbreviation for "Client URL Request Library" or why not the recursive + version: "curl URL Request Library". + + The cURL project produces two products: + + libcurl + + A client-side URL transfer library, supporting DICT, FILE, FTP, FTPS, + GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, + RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS + and WSS. + + libcurl supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, + Kerberos, SPNEGO, HTTP form based upload, proxies, cookies, user+password + authentication, file transfer resume, http proxy tunneling and more. + + libcurl is highly portable, it builds and works identically on numerous + platforms, including Solaris, NetBSD, FreeBSD, OpenBSD, Darwin, HP-UX, + IRIX, AIX, Tru64, Linux, UnixWare, HURD, Windows, Amiga, OS/2, macOS, + Ultrix, QNX, OpenVMS, RISC OS, Novell NetWare, DOS, Symbian, OSF, Android, + Minix, IBM TPF and more... + + libcurl is free, thread-safe, IPv6 compatible, feature rich, well + supported and fast. + + curl + + A command line tool for getting or sending data using URL syntax. + + Since curl uses libcurl, curl supports the same wide range of common + Internet protocols that libcurl does. + + We pronounce curl with an initial k sound. It rhymes with words like girl + and earl. This is a short WAV file to help you: + + https://media.merriam-webster.com/soundc11/c/curl0001.wav + + There are numerous sub-projects and related projects that also use the word + curl in the project names in various combinations, but you should take + notice that this FAQ is directed at the command-line tool named curl (and + libcurl the library), and may therefore not be valid for other curl-related + projects. (There is however a small section for the PHP/CURL in this FAQ.) + + 1.2 What is libcurl? + + libcurl is a reliable and portable library for doing Internet data transfers + using one or more of its supported Internet protocols. + + You can use libcurl freely in your application, be it open source, + commercial or closed-source. + + libcurl is most probably the most portable, most powerful and most often + used C-based multi-platform file transfer library on this planet - be it + open source or commercial. + + 1.3 What is curl not? + + curl is not a wget clone. That is a common misconception. Never, during + curl's development, have we intended curl to replace wget or compete on its + market. curl is targeted at single-shot file transfers. + + curl is not a website mirroring program. If you want to use curl to mirror + something: fine, go ahead and write a script that wraps around curl or use + libcurl to make it reality. + + curl is not an FTP site mirroring program. Sure, get and send FTP with curl + but if you want systematic and sequential behavior you should write a + script (or write a new program that interfaces libcurl) and do it. + + curl is not a PHP tool, even though it works perfectly well when used from + or with PHP (when using the PHP/CURL module). + + curl is not a program for a single operating system. curl exists, compiles, + builds and runs under a wide range of operating systems, including all + modern Unixes (and a bunch of older ones too), Windows, Amiga, OS/2, macOS, + QNX etc. + + 1.4 When will you make curl do XXXX ? + + We love suggestions of what to change in order to make curl and libcurl + better. We do however believe in a few rules when it comes to the future of + curl: + + curl -- the command line tool -- is to remain a non-graphical command line + tool. If you want GUIs or fancy scripting capabilities, you should look for + another tool that uses libcurl. + + We do not add things to curl that other small and available tools already do + well at the side. curl's output can be piped into another program or + redirected to another file for the next program to interpret. + + We focus on protocol related issues and improvements. If you want to do more + magic with the supported protocols than curl currently does, chances are + good we will agree. If you want to add more protocols, we may agree. + + If you want someone else to do all the work while you wait for us to + implement it for you, that is not a friendly attitude. We spend a + considerable time already on maintaining and developing curl. In order to + get more out of us, you should consider trading in some of your time and + effort in return. Simply go to the GitHub repository which resides at + https://github.com/curl/curl, fork the project, and create pull requests + with your proposed changes. + + If you write the code, chances are better that it will get into curl faster. + + 1.5 Who makes curl? + + curl and libcurl are not made by any single individual. Daniel Stenberg is + project leader and main developer, but other persons' submissions are + important and crucial. Anyone can contribute and post their changes and + improvements and have them inserted in the main sources (of course on the + condition that developers agree that the fixes are good). + + The full list of all contributors is found in the docs/THANKS file. + + curl is developed by a community, with Daniel at the wheel. + + 1.6 What do you get for making curl? + + Project cURL is entirely free and open. We do this voluntarily, mostly in + our spare time. Companies may pay individual developers to work on curl. + This is not controlled by nor supervised in any way by the curl project. + + We get help from companies. Haxx provides website, bandwidth, mailing lists + etc, GitHub hosts the primary git repository and other services like the bug + tracker at https://github.com/curl/curl. Also again, some companies have + sponsored certain parts of the development in the past and I hope some will + continue to do so in the future. + + If you want to support our project, consider a donation or a banner-program + or even better: by helping us with coding, documenting or testing etc. + + See also: https://curl.se/sponsors.html + + 1.7 What about CURL from curl.com? + + During the summer of 2001, curl.com was busy advertising their client-side + programming language for the web, named CURL. + + We are in no way associated with curl.com or their CURL programming + language. + + Our project name curl has been in effective use since 1998. We were not the + first computer related project to use the name "curl" and do not claim any + rights to the name. + + We recognize that we will be living in parallel with curl.com and wish them + every success. + + 1.8 I have a problem, who do I mail? + + Please do not mail any single individual unless you really need to. Keep + curl-related questions on a suitable mailing list. All available mailing + lists are listed in the MANUAL document and online at + https://curl.se/mail/ + + Keeping curl-related questions and discussions on mailing lists allows + others to join in and help, to share their ideas, to contribute their + suggestions and to spread their wisdom. Keeping discussions on public mailing + lists also allows for others to learn from this (both current and future + users thanks to the web based archives of the mailing lists), thus saving us + from having to repeat ourselves even more. Thanks for respecting this. + + If you have found or simply suspect a security problem in curl or libcurl, + submit all the details at https://hackerone.one/curl. On there we keep the + issue private while we investigate, confirm it, work and validate a fix and + agree on a time schedule for publication etc. That way we produce a fix in a + timely manner before the flaw is announced to the world, reducing the impact + the problem risks having on existing users. + + Security issues can also be taking to the curl security team by emailing + security at curl.se (closed list of receivers, mails are not disclosed). + + 1.9 Where do I buy commercial support for curl? + + curl is fully open source. It means you can hire any skilled engineer to fix + your curl-related problems. + + We list available alternatives on the curl website: + https://curl.se/support.html + + 1.10 How many are using curl? + + It is impossible to tell. + + We do not know how many users that knowingly have installed and use curl. + + We do not know how many users that use curl without knowing that they are in + fact using it. + + We do not know how many users that downloaded or installed curl and then + never use it. + + In 2020, we estimate that curl runs in roughly ten billion installations + world wide. + + 1.11 Why do you not update ca-bundle.crt + + In the cURL project we have decided not to attempt to keep this file updated + (or even present) since deciding what to add to a ca cert bundle is an + undertaking we have not been ready to accept, and the one we can get from + Mozilla is perfectly fine so there is no need to duplicate that work. + + Today, with many services performed over HTTPS, every operating system + should come with a default ca cert bundle that can be deemed somewhat + trustworthy and that collection (if reasonably updated) should be deemed to + be a lot better than a private curl version. + + If you want the most recent collection of ca certs that Mozilla Firefox + uses, we recommend that you extract the collection yourself from Mozilla + Firefox (by running 'make ca-bundle), or by using our online service setup + for this purpose: https://curl.se/docs/caextract.html + + 1.12 I have a problem who, can I chat with? + + There is a bunch of friendly people hanging out in the #curl channel on the + IRC network libera.chat. If you are polite and nice, chances are good that + you can get -- or provide -- help instantly. + + 1.13 curl's ECCN number? + + The US government restricts exports of software that contains or uses + cryptography. When doing so, the Export Control Classification Number (ECCN) + is used to identify the level of export control etc. + + Apache Software Foundation gives a good explanation of ECCNs at + https://www.apache.org/dev/crypto.html + + We believe curl's number might be ECCN 5D002, another possibility is + 5D992. It seems necessary to write them (the authority that administers ECCN + numbers), asking to confirm. + + Comprehensible explanations of the meaning of such numbers and how to obtain + them (resp.) are here + + https://www.bis.doc.gov/licensing/exportingbasics.htm + https://www.bis.doc.gov/licensing/do_i_needaneccn.html + + An incomprehensible description of the two numbers above is here + https://www.bis.doc.gov/index.php/documents/new-encryption/1653-ccl5-pt2-3 + + 1.14 How do I submit my patch? + + We strongly encourage you to submit changes and improvements directly as + "pull requests" on GitHub: https://github.com/curl/curl/pulls + + If you for any reason cannot or will not deal with GitHub, send your patch to + the curl-library mailing list. We are many subscribers there and there are + lots of people who can review patches, comment on them and "receive" them + properly. + + Lots of more details are found in the CONTRIBUTE.md and INTERNALS.md + documents. + + 1.15 How do I port libcurl to my OS? + + Here's a rough step-by-step: + + 1. copy a suitable lib/config-*.h file as a start to lib/config-[youros].h + + 2. edit lib/config-[youros].h to match your OS and setup + + 3. edit lib/curl_setup.h to include config-[youros].h when your OS is + detected by the preprocessor, in the style others already exist + + 4. compile lib/*.c and make them into a library + + +2. Install Related Problems + + 2.1 configure fails when using static libraries + + You may find that configure fails to properly detect the entire dependency + chain of libraries when you provide static versions of the libraries that + configure checks for. + + The reason why static libraries is much harder to deal with is that for them + we do not get any help but the script itself must know or check what more + libraries that are needed (with shared libraries, that dependency "chain" is + handled automatically). This is a error-prone process and one that also + tends to vary over time depending on the release versions of the involved + components and may also differ between operating systems. + + For that reason, configure does few attempts to actually figure this out and + you are instead encouraged to set LIBS and LDFLAGS accordingly when you + invoke configure, and point out the needed libraries and set the necessary + flags yourself. + + 2.2 Does curl work with other SSL libraries? + + curl has been written to use a generic SSL function layer internally, and + that SSL functionality can then be provided by one out of many different SSL + backends. + + curl can be built to use one of the following SSL alternatives: OpenSSL, + libressl, BoringSSL, AWS-LC, GnuTLS, wolfSSL, mbedTLS, Secure Transport + (native iOS/OS X), Schannel (native Windows), BearSSL or Rustls. They all + have their pros and cons, and we try to maintain a comparison of them here: + https://curl.se/docs/ssl-compared.html + + 2.3 How do I upgrade curl.exe in Windows? + + The curl tool that is shipped as an integrated component of Windows 10 and + Windows 11 is managed by Microsoft. If you were to delete the file or + replace it with a newer version downloaded from https://curl.se/windows, + then Windows Update will cease to work on your system. + + There is no way to independently force an upgrade of the curl.exe that is + part of Windows other than through the regular Windows update process. There + is also nothing the curl project itself can do about this, since this is + managed and controlled entirely by Microsoft as owners of the operating + system. + + You can always download and install the latest version of curl for Windows + from https://curl.se/windows into a separate location. + + 2.4 Does curl support SOCKS (RFC 1928) ? + + Yes, SOCKS 4 and 5 are supported. + +3. Usage problems + + 3.1 curl: (1) SSL is disabled, https: not supported + + If you get this output when trying to get anything from an HTTPS server, it + means that the instance of curl/libcurl that you are using was built without + support for this protocol. + + This could have happened if the configure script that was run at build time + could not find all libs and include files curl requires for SSL to work. If + the configure script fails to find them, curl is simply built without SSL + support. + + To get HTTPS support into a curl that was previously built but that reports + that HTTPS is not supported, you should dig through the document and logs + and check out why the configure script does not find the SSL libs and/or + include files. + + Also, check out the other paragraph in this FAQ labeled "configure does not + find OpenSSL even when it is installed". + + 3.2 How do I tell curl to resume a transfer? + + curl supports resumed transfers both ways on both FTP and HTTP. + Try the -C option. + + 3.3 Why does my posting using -F not work? + + You cannot arbitrarily use -F or -d, the choice between -F or -d depends on + the HTTP operation you need curl to do and what the web server that will + receive your post expects. + + If the form you are trying to submit uses the type 'multipart/form-data', + then and only then you must use the -F type. In all the most common cases, + you should use -d which then causes a posting with the type + 'application/x-www-form-urlencoded'. + + This is described in some detail in the MANUAL and TheArtOfHttpScripting + documents, and if you do not understand it the first time, read it again + before you post questions about this to the mailing list. Also, try reading + through the mailing list archives for old postings and questions regarding + this. + + 3.4 How do I tell curl to run custom FTP commands? + + You can tell curl to perform optional commands both before and/or after a + file transfer. Study the -Q/--quote option. + + Since curl is used for file transfers, you do not normally use curl to + perform FTP commands without transferring anything. Therefore you must + always specify a URL to transfer to/from even when doing custom FTP + commands, or use -I which implies the "no body" option sent to libcurl. + + 3.5 How can I disable the Accept: */* header? + + You can change all internally generated headers by adding a replacement with + the -H/--header option. By adding a header with empty contents you safely + disable that one. Use -H "Accept:" to disable that specific header. + + 3.6 Does curl support ASP, XML, XHTML or HTML version Y? + + To curl, all contents are alike. It does not matter how the page was + generated. It may be ASP, PHP, Perl, shell-script, SSI or plain HTML + files. There is no difference to curl and it does not even know what kind of + language that generated the page. + + See also item 3.14 regarding JavaScript. + + 3.7 Can I use curl to delete/rename a file through FTP? + + Yes. You specify custom FTP commands with -Q/--quote. + + One example would be to delete a file after you have downloaded it: + + curl -O ftp://example.com/coolfile -Q '-DELE coolfile' + + or rename a file after upload: + + curl -T infile ftp://example.com/dir/ -Q "-RNFR infile" -Q "-RNTO newname" + + 3.8 How do I tell curl to follow HTTP redirects? + + curl does not follow so-called redirects by default. The Location: header + that informs the client about this is only interpreted if you are using the + -L/--location option. As in: + + curl -L http://example.com + + Not all redirects are HTTP ones, see 4.14 + + 3.9 How do I use curl in my favorite programming language? + + Many programming languages have interfaces/bindings that allow you to use + curl without having to use the command line tool. If you are fluent in such + a language, you may prefer to use one of these interfaces instead. + + Find out more about which languages that support curl directly, and how to + install and use them, in the libcurl section of the curl website: + https://curl.se/libcurl/ + + All the various bindings to libcurl are made by other projects and people, + outside of the cURL project. The cURL project itself only produces libcurl + with its plain C API. If you do not find anywhere else to ask you can ask + about bindings on the curl-library list too, but be prepared that people on + that list may not know anything about bindings. + + In December 2021, there were interfaces available for the following + languages: Ada95, Basic, C, C++, Ch, Cocoa, D, Delphi, Dylan, Eiffel, + Euphoria, Falcon, Ferite, Gambas, glib/GTK+, Go, Guile, Harbour, Haskell, + Java, Julia, Lisp, Lua, Mono, .NET, node.js, Object-Pascal, OCaml, Pascal, + Perl, PHP, PostgreSQL, Python, R, Rexx, Ring, RPG, Ruby, Rust, Scheme, + Scilab, S-Lang, Smalltalk, SP-Forth, SPL, Tcl, Visual Basic, Visual FoxPro, + Q, wxwidgets, XBLite and Xoho. By the time you read this, additional ones + may have appeared. + + 3.10 What about SOAP, WebDAV, XML-RPC or similar protocols over HTTP? + + curl adheres to the HTTP spec, which basically means you can play with *any* + protocol that is built on top of HTTP. Protocols such as SOAP, WEBDAV and + XML-RPC are all such ones. You can use -X to set custom requests and -H to + set custom headers (or replace internally generated ones). + + Using libcurl is of course just as good and you would just use the proper + library options to do the same. + + 3.11 How do I POST with a different Content-Type? + + You can always replace the internally generated headers with -H/--header. + To make a simple HTTP POST with text/xml as content-type, do something like: + + curl -d "datatopost" -H "Content-Type: text/xml" [URL] + + 3.12 Why do FTP-specific features over HTTP proxy fail? + + Because when you use an HTTP proxy, the protocol spoken on the network will + be HTTP, even if you specify an FTP URL. This effectively means that you + normally cannot use FTP-specific features such as FTP upload and FTP quote + etc. + + There is one exception to this rule, and that is if you can "tunnel through" + the given HTTP proxy. Proxy tunneling is enabled with a special option (-p) + and is generally not available as proxy admins usually disable tunneling to + ports other than 443 (which is used for HTTPS access through proxies). + + 3.13 Why do my single/double quotes fail? + + To specify a command line option that includes spaces, you might need to + put the entire option within quotes. Like in: + + curl -d " with spaces " example.com + + or perhaps + + curl -d ' with spaces ' example.com + + Exactly what kind of quotes and how to do this is entirely up to the shell + or command line interpreter that you are using. For most unix shells, you + can more or less pick either single (') or double (") quotes. For + Windows/DOS command prompts you must use double (") quotes, and if the + option string contains inner double quotes you can escape them with a + backslash. + + For Windows powershell the arguments are not always passed on as expected + because curl is not a powershell script. You may or may not be able to use + single quotes. To escape inner double quotes seems to require a + backslash-backtick escape sequence and the outer quotes as double quotes. + + Please study the documentation for your particular environment. Examples in + the curl docs will use a mix of both of these as shown above. You must + adjust them to work in your environment. + + Remember that curl works and runs on more operating systems than most single + individuals have ever tried. + + 3.14 Does curl support JavaScript or PAC (automated proxy config)? + + Many web pages do magic stuff using embedded JavaScript. curl and libcurl + have no built-in support for that, so it will be treated just like any other + contents. + + .pac files are a Netscape invention and are sometimes used by organizations + to allow them to differentiate which proxies to use. The .pac contents is + just a JavaScript program that gets invoked by the browser and that returns + the name of the proxy to connect to. Since curl does not support JavaScript, + it cannot support .pac proxy configuration either. + + Some workarounds usually suggested to overcome this JavaScript dependency: + + Depending on the JavaScript complexity, write up a script that translates it + to another language and execute that. + + Read the JavaScript code and rewrite the same logic in another language. + + Implement a JavaScript interpreter, people have successfully used the + Mozilla JavaScript engine in the past. + + Ask your admins to stop this, for a static proxy setup or similar. + + 3.15 Can I do recursive fetches with curl? + + No. curl itself has no code that performs recursive operations, such as + those performed by wget and similar tools. + + There exists wrapper scripts with that functionality (for example the + curlmirror perl script), and you can write programs based on libcurl to do + it, but the command line tool curl itself cannot. + + 3.16 What certificates do I need when I use SSL? + + There are three different kinds of "certificates" to keep track of when we + talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl. + + CLIENT CERTIFICATE + + The server you communicate with may require that you can provide this in + order to prove that you actually are who you claim to be. If the server + does not require this, you do not need a client certificate. + + A client certificate is always used together with a private key, and the + private key has a pass phrase that protects it. + + SERVER CERTIFICATE + + The server you communicate with has a server certificate. You can and should + verify this certificate to make sure that you are truly talking to the real + server and not a server impersonating it. + + CERTIFICATE AUTHORITY CERTIFICATE ("CA cert") + + You often have several CA certs in a CA cert bundle that can be used to + verify a server certificate that was signed by one of the authorities in the + bundle. curl does not come with a CA cert bundle but most curl installs + provide one. You can also override the default. + + The server certificate verification process is made by using a Certificate + Authority certificate ("CA cert") that was used to sign the server + certificate. Server certificate verification is enabled by default in curl + and libcurl and is often the reason for problems as explained in FAQ entry + 4.12 and the SSLCERTS document + (https://curl.se/docs/sslcerts.html). Server certificates that are + "self-signed" or otherwise signed by a CA that you do not have a CA cert + for, cannot be verified. If the verification during a connect fails, you are + refused access. You then need to explicitly disable the verification to + connect to the server. + + 3.17 How do I list the root directory of an FTP server? + + There are two ways. The way defined in the RFC is to use an encoded slash + in the first path part. List the "/tmp" directory like this: + + curl ftp://ftp.example.com/%2ftmp/ + + or the not-quite-kosher-but-more-readable way, by simply starting the path + section of the URL with a slash: + + curl ftp://ftp.example.com//tmp/ + + 3.18 Can I use curl to send a POST/PUT and not wait for a response? + + No. + + You can easily write your own program using libcurl to do such stunts. + + 3.19 How do I get HTTP from a host using a specific IP address? + + For example, you may be trying out a website installation that is not yet in + the DNS. Or you have a site using multiple IP addresses for a given host + name and you want to address a specific one out of the set. + + Set a custom Host: header that identifies the server name you want to reach + but use the target IP address in the URL: + + curl --header "Host: www.example.com" http://127.0.0.1/ + + You can also opt to add faked host name entries to curl with the --resolve + option. That has the added benefit that things like redirects will also work + properly. The above operation would instead be done as: + + curl --resolve www.example.com:80:127.0.0.1 http://www.example.com/ + + 3.20 How to SFTP from my user's home directory? + + Contrary to how FTP works, SFTP and SCP URLs specify the exact directory to + work with. It means that if you do not specify that you want the user's home + directory, you get the actual root directory. + + To specify a file in your user's home directory, you need to use the correct + URL syntax which for SFTP might look similar to: + + curl -O -u user:password sftp://example.com/~/file.txt + + and for SCP it is just a different protocol prefix: + + curl -O -u user:password scp://example.com/~/file.txt + + 3.21 Protocol xxx not supported or disabled in libcurl + + When passing on a URL to curl to use, it may respond that the particular + protocol is not supported or disabled. The particular way this error message + is phrased is because curl does not make a distinction internally of whether + a particular protocol is not supported (i.e. never got any code added that + knows how to speak that protocol) or if it was explicitly disabled. curl can + be built to only support a given set of protocols, and the rest would then + be disabled or not supported. + + Note that this error will also occur if you pass a wrongly spelled protocol + part as in "htpt://example.com" or as in the less evident case if you prefix + the protocol part with a space as in " http://example.com/". + + 3.22 curl -X gives me HTTP problems + + In normal circumstances, -X should hardly ever be used. + + By default you use curl without explicitly saying which request method to + use when the URL identifies an HTTP transfer. If you just pass in a URL like + "curl http://example.com" it will use GET. If you use -d or -F curl will use + POST, -I will cause a HEAD and -T will make it a PUT. + + If for whatever reason you are not happy with these default choices that curl + does for you, you can override those request methods by specifying -X + [WHATEVER]. This way you can for example send a DELETE by doing "curl -X + DELETE [URL]". + + It is thus pointless to do "curl -XGET [URL]" as GET would be used + anyway. In the same vein it is pointless to do "curl -X POST -d data + [URL]"... But you can make a fun and somewhat rare request that sends a + request-body in a GET request with something like "curl -X GET -d data + [URL]" + + Note that -X does not actually change curl's behavior as it only modifies the + actual string sent in the request, but that may of course trigger a + different set of events. + + Accordingly, by using -XPOST on a command line that for example would follow + a 303 redirect, you will effectively prevent curl from behaving + correctly. Be aware. + + +4. Running Problems + + 4.2 Why do I get problems when I use & or % in the URL? + + In general Unix shells, the & symbol is treated specially and when used, it + runs the specified command in the background. To safely send the & as a part + of a URL, you should quote the entire URL by using single (') or double (") + quotes around it. Similar problems can also occur on some shells with other + characters, including ?*!$~(){}<>\|;`. When in doubt, quote the URL. + + An example that would invoke a remote CGI that uses &-symbols could be: + + curl 'http://www.example.com/cgi-bin/query?text=yes&q=curl' + + In Windows, the standard DOS shell treats the percent sign specially and you + need to use TWO percent signs for each single one you want to use in the + URL. + + If you want a literal percent sign to be part of the data you pass in a POST + using -d/--data you must encode it as '%25' (which then also needs the + percent sign doubled on Windows machines). + + 4.3 How can I use {, }, [ or ] to specify multiple URLs? + + Because those letters have a special meaning to the shell, to be used in + a URL specified to curl you must quote them. + + An example that downloads two URLs (sequentially) would be: + + curl '{curl,www}.haxx.se' + + To be able to use those characters as actual parts of the URL (without using + them for the curl URL "globbing" system), use the -g/--globoff option: + + curl -g 'www.example.com/weirdname[].html' + + 4.4 Why do I get downloaded data even though the web page does not exist? + + curl asks remote servers for the page you specify. If the page does not exist + at the server, the HTTP protocol defines how the server should respond and + that means that headers and a "page" will be returned. That is simply how + HTTP works. + + By using the --fail option you can tell curl explicitly to not get any data + if the HTTP return code does not say success. + + 4.5 Why do I get return code XXX from an HTTP server? + + RFC 2616 clearly explains the return codes. This is a short transcript. Go + read the RFC for exact details: + + 4.5.1 "400 Bad Request" + + The request could not be understood by the server due to malformed + syntax. The client SHOULD NOT repeat the request without modifications. + + 4.5.2 "401 Unauthorized" + + The request requires user authentication. + + 4.5.3 "403 Forbidden" + + The server understood the request, but is refusing to fulfill it. + Authorization will not help and the request SHOULD NOT be repeated. + + 4.5.4 "404 Not Found" + + The server has not found anything matching the Request-URI. No indication + is given as to whether the condition is temporary or permanent. + + 4.5.5 "405 Method Not Allowed" + + The method specified in the Request-Line is not allowed for the resource + identified by the Request-URI. The response MUST include an Allow header + containing a list of valid methods for the requested resource. + + 4.5.6 "301 Moved Permanently" + + If you get this return code and an HTML output similar to this: + +

Moved Permanently

The document has moved here. + + it might be because you requested a directory URL but without the trailing + slash. Try the same operation again _with_ the trailing URL, or use the + -L/--location option to follow the redirection. + + 4.6 Can you tell me what error code 142 means? + + All curl error codes are described at the end of the man page, in the + section called "EXIT CODES". + + Error codes that are larger than the highest documented error code means + that curl has exited due to a crash. This is a serious error, and we + appreciate a detailed bug report from you that describes how we could go + ahead and repeat this. + + 4.7 How do I keep user names and passwords secret in curl command lines? + + This problem has two sides: + + The first part is to avoid having clear-text passwords in the command line + so that they do not appear in 'ps' outputs and similar. That is easily + avoided by using the "-K" option to tell curl to read parameters from a file + or stdin to which you can pass the secret info. curl itself will also + attempt to "hide" the given password by blanking out the option - this + does not work on all platforms. + + To keep the passwords in your account secret from the rest of the world is + not a task that curl addresses. You could of course encrypt them somehow to + at least hide them from being read by human eyes, but that is not what + anyone would call security. + + Also note that regular HTTP (using Basic authentication) and FTP passwords + are sent as cleartext across the network. All it takes for anyone to fetch + them is to listen on the network. Eavesdropping is easy. Use more secure + authentication methods (like Digest, Negotiate or even NTLM) or consider the + SSL-based alternatives HTTPS and FTPS. + + 4.8 I found a bug + + It is not a bug if the behavior is documented. Read the docs first. + Especially check out the KNOWN_BUGS file, it may be a documented bug. + + If it is a problem with a binary you have downloaded or a package for your + particular platform, try contacting the person who built the package/archive + you have. + + If there is a bug, read the BUGS document first. Then report it as described + in there. + + 4.9 curl cannot authenticate to a server that requires NTLM? + + NTLM support requires OpenSSL, GnuTLS, mbedTLS, Secure Transport, or + Microsoft Windows libraries at build-time to provide this functionality. + + 4.10 My HTTP request using HEAD, PUT or DELETE does not work + + Many web servers allow or demand that the administrator configures the + server properly for these requests to work on the web server. + + Some servers seem to support HEAD only on certain kinds of URLs. + + To fully grasp this, try the documentation for the particular server + software you are trying to interact with. This is not anything curl can do + anything about. + + 4.11 Why do my HTTP range requests return the full document? + + Because the range may not be supported by the server, or the server may + choose to ignore it and return the full document anyway. + + 4.12 Why do I get "certificate verify failed" ? + + When you invoke curl and get an error 60 error back it means that curl + could not verify that the server's certificate was good. curl verifies the + certificate using the CA cert bundle and verifying for which names the + certificate has been granted. + + To completely disable the certificate verification, use -k. This does + however enable man-in-the-middle attacks and makes the transfer INSECURE. + We strongly advise against doing this for more than experiments. + + If you get this failure with a CA cert bundle installed and used, the + server's certificate might not be signed by one of the CA's in your CA + store. It might for example be self-signed. You then correct this problem by + obtaining a valid CA cert for the server. Or again, decrease the security by + disabling this check. + + At times, you find that the verification works in your favorite browser but + fails in curl. When this happens, the reason is usually that the server + sends an incomplete cert chain. The server is mandated to send all + "intermediate certificates" but does not. This typically works with browsers + anyway since they A) cache such certs and B) supports AIA which downloads + such missing certificates on demand. This is a server misconfiguration. A + good way to figure out if this is the case it to use the SSL Labs server + test and check the certificate chain: https://www.ssllabs.com/ssltest/ + + Details are also in the SSLCERTS.md document, found online here: + https://curl.se/docs/sslcerts.html + + 4.13 Why is curl -R on Windows one hour off? + + Since curl 7.53.0 this issue should be fixed as long as curl was built with + any modern compiler that allows for a 64-bit curl_off_t type. For older + compilers or prior curl versions it may set a time that appears one hour off. + This happens due to a flaw in how Windows stores and uses file modification + times and it is not easily worked around. For more details read this: + https://www.codeproject.com/Articles/1144/Beating-the-Daylight-Savings-Time-bug-and-getting + + 4.14 Redirects work in browser but not with curl + + curl supports HTTP redirects well (see item 3.8). Browsers generally support + at least two other ways to perform redirects that curl does not: + + Meta tags. You can write an HTML tag that will cause the browser to redirect + to another given URL after a certain time. + + JavaScript. You can write a JavaScript program embedded in an HTML page that + redirects the browser to another given URL. + + There is no way to make curl follow these redirects. You must either + manually figure out what the page is set to do, or write a script that parses + the results and fetches the new URL. + + 4.15 FTPS does not work + + curl supports FTPS (sometimes known as FTP-SSL) both implicit and explicit + mode. + + When a URL is used that starts with FTPS://, curl assumes implicit SSL on + the control connection and will therefore immediately connect and try to + speak SSL. FTPS:// connections default to port 990. + + To use explicit FTPS, you use an FTP:// URL and the --ftp-ssl option (or one + of its related flavors). This is the most common method, and the one + mandated by RFC 4217. This kind of connection will then of course use the + standard FTP port 21 by default. + + 4.16 My HTTP POST or PUT requests are slow + + libcurl makes all POST and PUT requests (except for requests with a small + request body) use the "Expect: 100-continue" header. This header allows the + server to deny the operation early so that libcurl can bail out before having + to send any data. This is useful in authentication cases and others. + + However, many servers do not implement the Expect: stuff properly and if the + server does not respond (positively) within 1 second libcurl will continue + and send off the data anyway. + + You can disable libcurl's use of the Expect: header the same way you disable + any header, using -H / CURLOPT_HTTPHEADER, or by forcing it to use HTTP 1.0. + + 4.17 Non-functional connect timeouts + + In most Windows setups having a timeout longer than 21 seconds make no + difference, as it will only send 3 TCP SYN packets and no more. The second + packet sent three seconds after the first and the third six seconds after + the second. No more than three packets are sent, no matter how long the + timeout is set. + + See option TcpMaxConnectRetransmissions on this page: + https://support.microsoft.com/en-us/kb/175523/en-us + + Also, even on non-Windows systems there may run a firewall or anti-virus + software or similar that accepts the connection but does not actually do + anything else. This will make (lib)curl to consider the connection connected + and thus the connect timeout will not trigger. + + 4.18 file:// URLs containing drive letters (Windows, NetWare) + + When using curl to try to download a local file, one might use a URL + in this format: + + file://D:/blah.txt + + you will find that even if D:\blah.txt does exist, curl returns a 'file + not found' error. + + According to RFC 1738 (https://www.ietf.org/rfc/rfc1738.txt), + file:// URLs must contain a host component, but it is ignored by + most implementations. In the above example, 'D:' is treated as the + host component, and is taken away. Thus, curl tries to open '/blah.txt'. + If your system is installed to drive C:, that will resolve to 'C:\blah.txt', + and if that does not exist you will get the not found error. + + To fix this problem, use file:// URLs with *three* leading slashes: + + file:///D:/blah.txt + + Alternatively, if it makes more sense, specify 'localhost' as the host + component: + + file://localhost/D:/blah.txt + + In either case, curl should now be looking for the correct file. + + 4.19 Why does not curl return an error when the network cable is unplugged? + + Unplugging a cable is not an error situation. The TCP/IP protocol stack + was designed to be fault tolerant, so even though there may be a physical + break somewhere the connection should not be affected, just possibly + delayed. Eventually, the physical break will be fixed or the data will be + re-routed around the physical problem through another path. + + In such cases, the TCP/IP stack is responsible for detecting when the + network connection is irrevocably lost. Since with some protocols it is + perfectly legal for the client to wait indefinitely for data, the stack may + never report a problem, and even when it does, it can take up to 20 minutes + for it to detect an issue. The curl option --keepalive-time enables + keep-alive support in the TCP/IP stack which makes it periodically probe the + connection to make sure it is still available to send data. That should + reliably detect any TCP/IP network failure. + + TCP keep alive will not detect the network going down before the TCP/IP + connection is established (e.g. during a DNS lookup) or using protocols that + do not use TCP. To handle those situations, curl offers a number of timeouts + on its own. --speed-limit/--speed-time will abort if the data transfer rate + falls too low, and --connect-timeout and --max-time can be used to put an + overall timeout on the connection phase or the entire transfer. + + A libcurl-using application running in a known physical environment (e.g. + an embedded device with only a single network connection) may want to act + immediately if its lone network connection goes down. That can be achieved + by having the application monitor the network connection on its own using an + OS-specific mechanism, then signaling libcurl to abort (see also item 5.13). + + 4.20 curl does not return error for HTTP non-200 responses + + Correct. Unless you use -f (--fail). + + When doing HTTP transfers, curl will perform exactly what you are asking it + to do and if successful it will not return an error. You can use curl to + test your web server's "file not found" page (that gets 404 back), you can + use it to check your authentication protected web pages (that gets a 401 + back) and so on. + + The specific HTTP response code does not constitute a problem or error for + curl. It simply sends and delivers HTTP as you asked and if that worked, + everything is fine and dandy. The response code is generally providing more + higher level error information that curl does not care about. The error was + not in the HTTP transfer. + + If you want your command line to treat error codes in the 400 and up range + as errors and thus return a non-zero value and possibly show an error + message, curl has a dedicated option for that: -f (CURLOPT_FAILONERROR in + libcurl speak). + + You can also use the -w option and the variable %{response_code} to extract + the exact response code that was returned in the response. + +5. libcurl Issues + + 5.1 Is libcurl thread-safe? + + Yes. + + We have written the libcurl code specifically adjusted for multi-threaded + programs. libcurl will use thread-safe functions instead of non-safe ones if + your system has such. Note that you must never share the same handle in + multiple threads. + + There may be some exceptions to thread safety depending on how libcurl was + built. Please review the guidelines for thread safety to learn more: + https://curl.se/libcurl/c/threadsafe.html + + 5.2 How can I receive all data into a large memory chunk? + + [ See also the examples/getinmemory.c source ] + + You are in full control of the callback function that gets called every time + there is data received from the remote server. You can make that callback do + whatever you want. You do not have to write the received data to a file. + + One solution to this problem could be to have a pointer to a struct that you + pass to the callback function. You set the pointer using the + CURLOPT_WRITEDATA option. Then that pointer will be passed to the callback + instead of a FILE * to a file: + + /* imaginary struct */ + struct MemoryStruct { + char *memory; + size_t size; + }; + + /* imaginary callback function */ + size_t + WriteMemoryCallback(void *ptr, size_t size, size_t nmemb, void *data) + { + size_t realsize = size * nmemb; + struct MemoryStruct *mem = (struct MemoryStruct *)data; + + mem->memory = (char *)realloc(mem->memory, mem->size + realsize + 1); + if (mem->memory) { + memcpy(&(mem->memory[mem->size]), ptr, realsize); + mem->size += realsize; + mem->memory[mem->size] = 0; + } + return realsize; + } + + 5.3 How do I fetch multiple files with libcurl? + + libcurl has excellent support for transferring multiple files. You should + just repeatedly set new URLs with curl_easy_setopt() and then transfer it + with curl_easy_perform(). The handle you get from curl_easy_init() is not + only reusable, but you are even encouraged to reuse it if you can, as that + will enable libcurl to use persistent connections. + + 5.4 Does libcurl do Winsock initialization on win32 systems? + + Yes, if told to in the curl_global_init() call. + + 5.5 Does CURLOPT_WRITEDATA and CURLOPT_READDATA work on win32 ? + + Yes, but you cannot open a FILE * and pass the pointer to a DLL and have + that DLL use the FILE * (as the DLL and the client application cannot access + each others' variable memory areas). If you set CURLOPT_WRITEDATA you must + also use CURLOPT_WRITEFUNCTION as well to set a function that writes the + file, even if that simply writes the data to the specified FILE *. + Similarly, if you use CURLOPT_READDATA you must also specify + CURLOPT_READFUNCTION. + + 5.6 What about Keep-Alive or persistent connections? + + curl and libcurl have excellent support for persistent connections when + transferring several files from the same server. curl will attempt to reuse + connections for all URLs specified on the same command line/config file, and + libcurl will reuse connections for all transfers that are made using the + same libcurl handle. + + When you use the easy interface the connection cache is kept within the easy + handle. If you instead use the multi interface, the connection cache will be + kept within the multi handle and will be shared among all the easy handles + that are used within the same multi handle. + + 5.7 Link errors when building libcurl on Windows + + You need to make sure that your project, and all the libraries (both static + and dynamic) that it links against, are compiled/linked against the same run + time library. + + This is determined by the /MD, /ML, /MT (and their corresponding /M?d) + options to the command line compiler. /MD (linking against MSVCRT dll) seems + to be the most commonly used option. + + When building an application that uses the static libcurl library, you must + add -DCURL_STATICLIB to your CFLAGS. Otherwise the linker will look for + dynamic import symbols. If you are using Visual Studio, you need to instead + add CURL_STATICLIB in the "Preprocessor Definitions" section. + + If you get a linker error like "unknown symbol __imp__curl_easy_init ..." you + have linked against the wrong (static) library. If you want to use the + libcurl.dll and import lib, you do not need any extra CFLAGS, but use one of + the import libraries below. These are the libraries produced by the various + lib/Makefile.* files: + + Target: static lib. import lib for libcurl*.dll. + ----------------------------------------------------------- + MinGW: libcurl.a libcurldll.a + MSVC (release): libcurl.lib libcurl_imp.lib + MSVC (debug): libcurld.lib libcurld_imp.lib + Borland: libcurl.lib libcurl_imp.lib + + 5.8 libcurl.so.X: open failed: No such file or directory + + This is an error message you might get when you try to run a program linked + with a shared version of libcurl and your runtime linker (ld.so) could not + find the shared library named libcurl.so.X. (Where X is the number of the + current libcurl ABI, typically 3 or 4). + + You need to make sure that ld.so finds libcurl.so.X. You can do that + multiple ways, and it differs somewhat between different operating systems. + They are usually: + + * Add an option to the linker command line that specify the hard-coded path + the runtime linker should check for the lib (usually -R) + + * Set an environment variable (LD_LIBRARY_PATH for example) where ld.so + should check for libs + + * Adjust the system's config to check for libs in the directory where you have + put the library (like Linux's /etc/ld.so.conf) + + 'man ld.so' and 'man ld' will tell you more details + + 5.9 How does libcurl resolve host names? + + libcurl supports a large number of name resolve functions. One of them is + picked at build-time and will be used unconditionally. Thus, if you want to + change name resolver function you must rebuild libcurl and tell it to use a + different function. + + - The non-IPv6 resolver that can use one of four different host name resolve + calls (depending on what your system supports): + + A - gethostbyname() + B - gethostbyname_r() with 3 arguments + C - gethostbyname_r() with 5 arguments + D - gethostbyname_r() with 6 arguments + + - The IPv6-resolver that uses getaddrinfo() + + - The c-ares based name resolver that uses the c-ares library for resolves. + Using this offers asynchronous name resolves. + + - The threaded resolver (default option on Windows). It uses: + + A - gethostbyname() on plain IPv4 hosts + B - getaddrinfo() on IPv6 enabled hosts + + Also note that libcurl never resolves or reverse-lookups addresses given as + pure numbers, such as 127.0.0.1 or ::1. + + 5.10 How do I prevent libcurl from writing the response to stdout? + + libcurl provides a default built-in write function that writes received data + to stdout. Set the CURLOPT_WRITEFUNCTION to receive the data, or possibly + set CURLOPT_WRITEDATA to a different FILE * handle. + + 5.11 How do I make libcurl not receive the whole HTTP response? + + You make the write callback (or progress callback) return an error and + libcurl will then abort the transfer. + + 5.12 Can I make libcurl fake or hide my real IP address? + + No. libcurl operates on a higher level. Besides, faking IP address would + imply sending IP packets with a made-up source address, and then you normally + get a problem with receiving the packet sent back as they would then not be + routed to you. + + If you use a proxy to access remote sites, the sites will not see your local + IP address but instead the address of the proxy. + + Also note that on many networks NATs or other IP-munging techniques are used + that makes you see and use a different IP address locally than what the + remote server will see you coming from. You may also consider using + https://www.torproject.org/ . + + 5.13 How do I stop an ongoing transfer? + + With the easy interface you make sure to return the correct error code from + one of the callbacks, but none of them are instant. There is no function you + can call from another thread or similar that will stop it immediately. + Instead, you need to make sure that one of the callbacks you use returns an + appropriate value that will stop the transfer. Suitable callbacks that you + can do this with include the progress callback, the read callback and the + write callback. + + If you are using the multi interface, you can also stop a transfer by + removing the particular easy handle from the multi stack at any moment you + think the transfer is done or when you wish to abort the transfer. + + 5.14 Using C++ non-static functions for callbacks? + + libcurl is a C library, it does not know anything about C++ member functions. + + You can overcome this "limitation" with relative ease using a static + member function that is passed a pointer to the class: + + // f is the pointer to your object. + static size_t YourClass::func(void *buffer, size_t sz, size_t n, void *f) + { + // Call non-static member function. + static_cast(f)->nonStaticFunction(); + } + + // This is how you pass pointer to the static function: + curl_easy_setopt(hcurl, CURLOPT_WRITEFUNCTION, YourClass::func); + curl_easy_setopt(hcurl, CURLOPT_WRITEDATA, this); + + 5.15 How do I get an FTP directory listing? + + If you end the FTP URL you request with a slash, libcurl will provide you + with a directory listing of that given directory. You can also set + CURLOPT_CUSTOMREQUEST to alter what exact listing command libcurl would use + to list the files. + + The follow-up question tends to be how is a program supposed to parse the + directory listing. How does it know what's a file and what's a directory and + what's a symlink etc. If the FTP server supports the MLSD command then it + will return data in a machine-readable format that can be parsed for type. + The types are specified by RFC 3659 section 7.5.1. If MLSD is not supported + then you have to work with what you are given. The LIST output format is + entirely at the server's own liking and the NLST output does not reveal any + types and in many cases does not even include all the directory entries. + Also, both LIST and NLST tend to hide unix-style hidden files (those that + start with a dot) by default so you need to do "LIST -a" or similar to see + them. + + Example - List only directories. + ftp.funet.fi supports MLSD and ftp.kernel.org does not: + + curl -s ftp.funet.fi/pub/ -X MLSD | \ + perl -lne 'print if s/(?:^|;)type=dir;[^ ]+ (.+)$/$1/' + + curl -s ftp.kernel.org/pub/linux/kernel/ | \ + perl -lne 'print if s/^d[-rwx]{9}(?: +[^ ]+){7} (.+)$/$1/' + + If you need to parse LIST output in libcurl one such existing + list parser is available at https://cr.yp.to/ftpparse.html Versions of + libcurl since 7.21.0 also provide the ability to specify a wildcard to + download multiple files from one FTP directory. + + 5.16 I want a different time-out + + Sometimes users realize that CURLOPT_TIMEOUT and CURLOPT_CONNECTIMEOUT are + not sufficiently advanced or flexible to cover all the various use cases and + scenarios applications end up with. + + libcurl offers many more ways to time-out operations. A common alternative + is to use the CURLOPT_LOW_SPEED_LIMIT and CURLOPT_LOW_SPEED_TIME options to + specify the lowest possible speed to accept before to consider the transfer + timed out. + + The most flexible way is by writing your own time-out logic and using + CURLOPT_XFERINFOFUNCTION (perhaps in combination with other callbacks) and + use that to figure out exactly when the right condition is met when the + transfer should get stopped. + + 5.17 Can I write a server with libcurl? + + No. libcurl offers no functions or building blocks to build any kind of + Internet protocol server. libcurl is only a client-side library. For server + libraries, you need to continue your search elsewhere but there exist many + good open source ones out there for most protocols you could want a server + for. There are also really good stand-alone servers that have been tested + and proven for many years. There is no need for you to reinvent them. + + 5.18 Does libcurl use threads? + + Put simply: no, libcurl will execute in the same thread you call it in. All + callbacks will be called in the same thread as the one you call libcurl in. + + If you want to avoid your thread to be blocked by the libcurl call, you make + sure you use the non-blocking multi API which will do transfers + asynchronously - still in the same single thread. + + libcurl will potentially internally use threads for name resolving, if it + was built to work like that, but in those cases it will create the child + threads by itself and they will only be used and then killed internally by + libcurl and never exposed to the outside. + +6. License Issues + + curl and libcurl are released under a MIT/X derivative license. The license + is liberal and should not impose a problem for your project. This section is + just a brief summary for the cases we get the most questions. (Parts of this + section was much enhanced by Bjorn Reese.) + + We are not lawyers and this is not legal advice. You should probably consult + one if you want true and accurate legal insights without our prejudice. Note + especially that this section concerns the libcurl license only; compiling in + features of libcurl that depend on other libraries (e.g. OpenSSL) may affect + the licensing obligations of your application. + + 6.1 I have a GPL program, can I use the libcurl library? + + Yes + + Since libcurl may be distributed under the MIT/X derivative license, it can + be used together with GPL in any software. + + 6.2 I have a closed-source program, can I use the libcurl library? + + Yes + + libcurl does not put any restrictions on the program that uses the library. + + 6.3 I have a BSD licensed program, can I use the libcurl library? + + Yes + + libcurl does not put any restrictions on the program that uses the library. + + 6.4 I have a program that uses LGPL libraries, can I use libcurl? + + Yes + + The LGPL license does not clash with other licenses. + + 6.5 Can I modify curl/libcurl for my program and keep the changes secret? + + Yes + + The MIT/X derivative license practically allows you to do almost anything + with the sources, on the condition that the copyright texts in the sources + are left intact. + + 6.6 Can you please change the curl/libcurl license to XXXX? + + No. + + We have carefully picked this license after years of development and + discussions and a large amount of people have contributed with source code + knowing that this is the license we use. This license puts the restrictions + we want on curl/libcurl and it does not spread to other programs or + libraries that use it. It should be possible for everyone to use libcurl or + curl in their projects, no matter what license they already have in use. + + 6.7 What are my obligations when using libcurl in my commercial apps? + + Next to none. All you need to adhere to is the MIT-style license (stated in + the COPYING file) which basically says you have to include the copyright + notice in "all copies" and that you may not use the copyright holder's name + when promoting your software. + + You do not have to release any of your source code. + + You do not have to reveal or make public any changes to the libcurl source + code. + + You do not have to broadcast to the world that you are using libcurl within + your app. + + All we ask is that you disclose "the copyright notice and this permission + notice" somewhere. Most probably like in the documentation or in the section + where other third party dependencies already are mentioned and acknowledged. + + As can be seen here: https://curl.se/docs/companies.html and elsewhere, + more and more companies are discovering the power of libcurl and take + advantage of it even in commercial environments. + + +7. PHP/CURL Issues + + 7.1 What is PHP/CURL? + + The module for PHP that makes it possible for PHP programs to access curl- + functions from within PHP. + + In the cURL project we call this module PHP/CURL to differentiate it from + curl the command line tool and libcurl the library. The PHP team however + does not refer to it like this (for unknown reasons). They call it plain + CURL (often using all caps) or sometimes ext/curl, but both cause much + confusion to users which in turn gives us a higher question load. + + 7.2 Who wrote PHP/CURL? + + PHP/CURL was initially written by Sterling Hughes. + + 7.3 Can I perform multiple requests using the same handle? + + Yes - at least in PHP version 4.3.8 and later (this has been known to not + work in earlier versions, but the exact version when it started to work is + unknown to me). + + After a transfer, you just set new options in the handle and make another + transfer. This will make libcurl reuse the same connection if it can. + + 7.4 Does PHP/CURL have dependencies? + + PHP/CURL is a module that comes with the regular PHP package. It depends on + and uses libcurl, so you need to have libcurl installed properly before + PHP/CURL can be used. + +8. Development + + 8.1 Why does curl use C89? + + As with everything in curl, there is a history and we keep using what we have + used before until someone brings up the subject and argues for and works on + changing it. + + We started out using C89 in the 1990s because that was the only way to write + a truly portable C program and have it run as widely as possible. C89 was for + a long time even necessary to make things work on otherwise considered modern + platforms such as Windows. Today, we do not really know how many users that + still require the use of a C89 compiler. + + We will continue to use C89 for as long as nobody brings up a strong enough + reason for us to change our minds. The core developers of the project do not + feel restricted by this and we are not convinced that going C99 will offer us + enough of a benefit to warrant the risk of cutting off a share of users. + + 8.2 Will curl be rewritten? + + In one go: no. Little by little over time? Maybe. + + Over the years, new languages and clever operating environments come and go. + Every now and then the urge apparently arises to request that we rewrite curl + in another language. + + Some the most important properties in curl are maintaining the API and ABI + for libcurl and keeping the behavior for the command line tool. As long as we + can do that, everything else is up for discussion. To maintain the ABI, we + probably have to maintain a certain amount of code in C, and to remain rock + stable, we will never risk anything by rewriting a lot of things in one go. + That said, we can certainly offer more and more optional backends written in + other languages, as long as those backends can be plugged in at build-time. + Backends can be written in any language, but should probably provide APIs + usable from C to ease integration and transition. diff --git a/src/ext/curl/docs/FEATURES.md b/src/ext/curl/docs/FEATURES.md new file mode 100644 index 00000000..4a589e16 --- /dev/null +++ b/src/ext/curl/docs/FEATURES.md @@ -0,0 +1,219 @@ +# Features -- what curl can do + +## curl tool + + -

He then came up with the idea to make +currency-exchange calculations available to Internet Relay Chat (IRC) +users. All the necessary data were published on the Web; he just needed to +automate their retrieval. + +1996 +---- + +On November 11, 1996 the Brazilian developer Rafael Sagula wrote and released +HttpGet version 0.1. + +Daniel extended this existing command-line open-source tool. After a few minor +adjustments, it did just what he needed. The first release with Daniel's +additions was 0.2, released on December 17, 1996. Daniel quickly became the +new maintainer of the project. + +1997 +---- + +HttpGet 0.3 was released in January 1997 and now it accepted HTTP URLs on the +command line. + +HttpGet 1.0 was released on April 8 1997 with brand new HTTP proxy support. + +We soon found and fixed support for getting currencies over GOPHER. Once FTP +download support was added, the name of the project was changed and urlget 2.0 +was released in August 1997. The http-only days were already passed. + +Version 2.2 was released on August 14 1997 and introduced support to build for +and run on Windows and Solaris. + +November 24 1997: Version 3.1 added FTP upload support. + +Version 3.5 added support for HTTP POST. + +1998 +---- + +February 4: urlget 3.10 + +February 9: urlget 3.11 + +March 14: urlget 3.12 added proxy authentication. + +The project slowly grew bigger. With upload capabilities, the name was once +again misleading and a second name change was made. On March 20, 1998 curl 4 +was released. (The version numbering from the previous names was kept.) + +(Unrelated to this project a company called Curl Corporation registered a US +trademark on the name "CURL" on May 18 1998. That company had then already +registered the curl.com domain back in November of the previous year. All this +was revealed to us much later.) + +SSL support was added, powered by the SSLeay library. + +August: first announcement of curl on freshmeat.net. + +October: with the curl 4.9 release and the introduction of cookie support, +curl was no longer released under the GPL license. Now we are at 4000 lines of +code, we switched over to the MPL license to restrict the effects of +"copyleft". + +November: configure script and reported successful compiles on several +major operating systems. The never-quite-understood -F option was added and +curl could now simulate quite a lot of a browser. TELNET support was added. + +Curl 5 was released in December 1998 and introduced the first ever curl man +page. People started making Linux RPM packages out of it. + +1999 +---- + +January: DICT support added. + +OpenSSL took over and SSLeay was abandoned. + +May: first Debian package. + +August: LDAP:// and FILE:// support added. The curl website gets 1300 visits +weekly. Moved site to curl.haxx.nu. + +September: Released curl 6.0. 15000 lines of code. + +December 28: added the project on Sourceforge and started using its services +for managing the project. + +2000 +---- + +Spring: major internal overhaul to provide a suitable library interface. +The first non-beta release was named 7.1 and arrived in August. This offered +the easy interface and turned out to be the beginning of actually getting +other software and programs to be based on and powered by libcurl. Almost +20000 lines of code. + +June: the curl site moves to "curl.haxx.se" + +August, the curl website gets 4000 visits weekly. + +The PHP guys adopted libcurl already the same month, when the first ever third +party libcurl binding showed up. CURL has been a supported module in PHP since +the release of PHP 4.0.2. This would soon get followers. More than 16 +different bindings exist at the time of this writing. + +September: kerberos4 support was added. + +November: started the work on a test suite for curl. It was later re-written +from scratch again. The libcurl major SONAME number was set to 1. + +2001 +---- + +January: Daniel released curl 7.5.2 under a new license again: MIT (or +MPL). The MIT license is extremely liberal and can be combined with GPL +in other projects. This would finally put an end to the "complaints" from +people involved in GPLed projects that previously were prohibited from using +libcurl while it was released under MPL only. (Due to the fact that MPL is +deemed "GPL incompatible".) + +March 22: curl supports HTTP 1.1 starting with the release of 7.7. This +also introduced libcurl's ability to do persistent connections. 24000 lines of +code. The libcurl major SONAME number was bumped to 2 due to this overhaul. +The first experimental ftps:// support was added. + +August: The curl website gets 8000 visits weekly. Curl Corporation contacted +Daniel to discuss "the name issue". After Daniel's reply, they have never +since got back in touch again. + +September: libcurl 7.9 introduces cookie jar and `curl_formadd()`. During the +forthcoming 7.9.x releases, we introduced the multi interface slowly and +without many whistles. + +September 25: curl (7.7.2) is bundled in Mac OS X (10.1) for the first time. It was +already becoming more and more of a standard utility of Linux distributions +and a regular in the BSD ports collections. + +2002 +---- + +June: the curl website gets 13000 visits weekly. curl and libcurl is +35000 lines of code. Reported successful compiles on more than 40 combinations +of CPUs and operating systems. + +To estimate the number of users of the curl tool or libcurl library is next to +impossible. Around 5000 downloaded packages each week from the main site gives +a hint, but the packages are mirrored extensively, bundled with numerous OS +distributions and otherwise retrieved as part of other software. + +October 1: with the release of curl 7.10 it is released under the MIT license +only. + +Starting with 7.10, curl verifies SSL server certificates by default. + +2003 +---- + +January: Started working on the distributed curl tests.

Similarly, a client never accepts cookies set directly for the + top-level domain like for example `.com`.

With that bit set, libcurl will +attempt to reuse existing HTTP/2 connections and just add a new stream over +that when doing subsequent parallel requests. + +While libcurl sets up a connection to an HTTP server there is a period during +which it does not know if it can pipeline or do multiplexing and if you add +new transfers in that period, libcurl will default to start new connections +for those transfers. With the new option `CURLOPT_PIPEWAIT` (added in 7.43.0), +you can ask that a transfer should rather wait and see in case there is a +connection for the same host in progress that might end up being possible to +multiplex on. It favors keeping the number of connections low to the cost of +slightly longer time to first byte transferred. + +Applications +------------ + +We hide HTTP/2's binary nature and convert received HTTP/2 traffic to headers +in HTTP 1.1 style.

This strategy is +similar to IPv4/6 happy eyeballing where the alternate address family is used +in parallel after a short delay. + +The IPv4/6 eyeballing has a default of 200ms and you may override that via +`--happy-eyeballs-timeout-ms value`. Since HTTP/3 is still relatively new, we +decided to use this timeout also for the HTTP eyeballing - with a slight +twist. + +The `happy-eyeballs-timeout-ms` value is the **hard** timeout, meaning after +that time expired, a TLS connection is opened in addition to negotiate HTTP/2 +or HTTP/1.1. At half of that value - currently - is the **soft** timeout. The +soft timeout fires, when there has been **no data at all** seen from the +server on the HTTP/3 connection. + +So, without you specifying anything, the hard timeout is 200ms and the soft is 100ms: + + * Ideally, the whole QUIC handshake happens and curl has an HTTP/3 connection + in less than 100ms. + * When QUIC is not supported (or UDP does not work for this network path), no + reply is seen and the HTTP/2 TLS+TCP connection starts 100ms later. + * In the worst case, UDP replies start before 100ms, but drag on. This will + start the TLS+TCP connection after 200ms. + * When the QUIC handshake fails, the TLS+TCP connection is attempted right + away. For example, when the QUIC server presents the wrong certificate. + +The whole transfer only fails, when **both** QUIC and TLS+TCP fail to +handshake or time out. + +Note that all this happens in addition to IP version happy eyeballing. If the +name resolution for the server gives more than one IP address, curl will try +all those until one succeeds - just as with all other protocols. If those IP +addresses contain both IPv6 and IPv4, those attempts will happen, delayed, in +parallel (the actual eyeballing). + +## Known Bugs + +Check out the [list of known HTTP3 bugs](https://curl.se/docs/knownbugs.html#HTTP3). + +# HTTP/3 Test server + +This is not advice on how to run anything in production.

See +[CURL-DISABLE](CURL-DISABLE.md) for the full list. + +If you want to set any of these defines you have the following options: + + - Modify `lib/config-win32.h` + - Modify `lib/curl_setup.h` + - Modify `winbuild/Makefile.vc` + - Modify the "Preprocessor Definitions" in the libcurl project + +Note: The pre-processor settings can be found using the Visual Studio IDE +under "Project -> Properties -> Configuration Properties -> C/C++ -> +Preprocessor". + +## Using BSD-style lwIP instead of Winsock TCP/IP stack in Win32 builds + +In order to compile libcurl and curl using BSD-style lwIP TCP/IP stack it is +necessary to make the definition of the preprocessor symbol `USE_LWIPSOCK` +visible to libcurl and curl compilation processes. To set this definition you +have the following alternatives: + + - Modify `lib/config-win32.h` and `src/config-win32.h` + - Modify `winbuild/Makefile.vc` + - Modify the "Preprocessor Definitions" in the libcurl project + +Note: The pre-processor settings can be found using the Visual Studio IDE +under "Project -> Properties -> Configuration Properties -> C/C++ -> +Preprocessor". + +Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, in +order to use it with your program it is mandatory that your program includes +lwIP header file `` (or another lwIP header that includes this) +before including any libcurl header. Your program does not need the +`USE_LWIPSOCK` preprocessor definition which is for libcurl internals only. + +Compilation has been verified with lwIP 1.4.0. + +This BSD-style lwIP TCP/IP stack support must be considered experimental given +that it has been verified that lwIP 1.4.0 still needs some polish, and libcurl +might yet need some additional adjustment. + +## Important static libcurl usage note + +When building an application that uses the static libcurl library on Windows, +you must add `-DCURL_STATICLIB` to your `CFLAGS`. Otherwise the linker will +look for dynamic import symbols. + +## Legacy Windows and SSL + +Schannel (from Windows SSPI), is the native SSL library in Windows. However, +Schannel in Windows <= XP is unable to connect to servers that +no longer support the legacy handshakes and algorithms used by those +versions. If you will be using curl in one of those earlier versions of +Windows you should choose another SSL backend such as OpenSSL. + +# Apple Platforms (macOS, iOS, tvOS, watchOS, and their simulator counterparts) + +On modern Apple operating systems, curl can be built to use Apple's SSL/TLS +implementation, Secure Transport, instead of OpenSSL. To build with Secure +Transport for SSL/TLS, use the configure option `--with-secure-transport`. + +When Secure Transport is in use, the curl options `--cacert` and `--capath` +and their libcurl equivalents, will be ignored, because Secure Transport uses +the certificates stored in the Keychain to evaluate whether or not to trust +the server. This, of course, includes the root certificates that ship with the +OS. The `--cert` and `--engine` options, and their libcurl equivalents, are +currently unimplemented in curl with Secure Transport. + +In general, a curl build for an Apple `ARCH/SDK/DEPLOYMENT_TARGET` combination +can be taken by providing appropriate values for `ARCH`, `SDK`, `DEPLOYMENT_TARGET` +below and running the commands: + +```bash +# Set these three according to your needs +export ARCH=x86_64 +export SDK=macosx +export DEPLOYMENT_TARGET=10.8 + +export CFLAGS="-arch $ARCH -isysroot $(xcrun -sdk $SDK --show-sdk-path) -m$SDK-version-min=$DEPLOYMENT_TARGET" +./configure --host=$ARCH-apple-darwin --prefix $(pwd)/artifacts --with-secure-transport +make -j8 +make install +``` + +Above will build curl for macOS platform with `x86_64` architecture and `10.8` as deployment target. + +Here is an example for iOS device: + +```bash +export ARCH=arm64 +export SDK=iphoneos +export DEPLOYMENT_TARGET=11.0 + +export CFLAGS="-arch $ARCH -isysroot $(xcrun -sdk $SDK --show-sdk-path) -m$SDK-version-min=$DEPLOYMENT_TARGET" +./configure --host=$ARCH-apple-darwin --prefix $(pwd)/artifacts --with-secure-transport +make -j8 +make install +``` + +Another example for watchOS simulator for macs with Apple Silicon: + +```bash +export ARCH=arm64 +export SDK=watchsimulator +export DEPLOYMENT_TARGET=5.0 + +export CFLAGS="-arch $ARCH -isysroot $(xcrun -sdk $SDK --show-sdk-path) -m$SDK-version-min=$DEPLOYMENT_TARGET" +./configure --host=$ARCH-apple-darwin --prefix $(pwd)/artifacts --with-secure-transport +make -j8 +make install +``` + +In all above, the built libraries and executables can be found in the +`artifacts` folder. + +# Android + +When building curl for Android it is recommended to use a Linux/macOS +environment since using curl's `configure` script is the easiest way to build +curl for Android. Before you can build curl for Android, you need to install +the Android NDK first. This can be done using the SDK Manager that is part of +Android Studio. Once you have installed the Android NDK, you need to figure +out where it has been installed and then set up some environment variables +before launching `configure`. On macOS, those variables could look like this +to compile for `aarch64` and API level 29: + +```bash +export ANDROID_NDK_HOME=~/Library/Android/sdk/ndk/25.1.8937393 # Point into your NDK. +export HOST_TAG=darwin-x86_64 # Same tag for Apple Silicon. Other OS values here: https://developer.android.com/ndk/guides/other_build_systems#overview +export TOOLCHAIN=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/$HOST_TAG +export AR=$TOOLCHAIN/bin/llvm-ar +export AS=$TOOLCHAIN/bin/llvm-as +export CC=$TOOLCHAIN/bin/aarch64-linux-android21-clang +export CXX=$TOOLCHAIN/bin/aarch64-linux-android21-clang++ +export LD=$TOOLCHAIN/bin/ld +export RANLIB=$TOOLCHAIN/bin/llvm-ranlib +export STRIP=$TOOLCHAIN/bin/llvm-strip +``` + +When building on Linux or targeting other API levels or architectures, you need +to adjust those variables accordingly. After that you can build curl like this: + + ./configure --host aarch64-linux-android --with-pic --disable-shared + +Note that this will not give you SSL/TLS support. If you need SSL/TLS, you +have to build curl against a SSL/TLS layer, e.g. OpenSSL, because it is +impossible for curl to access Android's native SSL/TLS layer. To build curl +for Android using OpenSSL, follow the OpenSSL build instructions and then +install `libssl.a` and `libcrypto.a` to `$TOOLCHAIN/sysroot/usr/lib` and copy +`include/openssl` to `$TOOLCHAIN/sysroot/usr/include`. Now you can build curl +for Android using OpenSSL like this: + +```bash +LIBS="-lssl -lcrypto -lc++" # For OpenSSL/BoringSSL. In general, you will need to the SSL/TLS layer's transitive dependencies if you are linking statically. +./configure --host aarch64-linux-android --with-pic --disable-shared --with-openssl="$TOOLCHAIN/sysroot/usr" +``` + +# IBM i + +For IBM i (formerly OS/400), you can use curl in two different ways: + +- Natively, running in the **ILE**. The obvious use is being able to call curl + from ILE C or RPG applications. + - You will need to build this from source. See `packages/OS400/README` for + the ILE specific build instructions. +- In the **PASE** environment, which runs AIX programs. curl will be built as + it would be on AIX. + - IBM provides builds of curl in their Yum repository for PASE software. + - To build from source, follow the Unix instructions. + +There are some additional limitations and quirks with curl on this platform; +they affect both environments. + +## Multi-threading notes + +By default, jobs in IBM i will not start with threading enabled. (Exceptions +include interactive PASE sessions started by `QP2TERM` or SSH.) If you use +curl in an environment without threading when options like asynchronous DNS +were enabled, you will get messages like: + +``` +getaddrinfo() thread failed to start +``` + +Do not panic. curl and your program are not broken. You can fix this by: + +- Set the environment variable `QIBM_MULTI_THREADED` to `Y` before starting + your program. This can be done at whatever scope you feel is appropriate. +- Alternatively, start the job with the `ALWMLTTHD` parameter set to `*YES`. + +# Cross compile + +Download and unpack the curl package. + +`cd` to the new directory. (e.g. `cd curl-7.12.3`) + +Set environment variables to point to the cross-compile toolchain and call +configure with any options you need. Be sure and specify the `--host` and +`--build` parameters at configuration time. The following script is an example +of cross-compiling for the IBM 405GP PowerPC processor using the toolchain on +Linux. + +```bash +#! /bin/sh + +export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin +export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include" +export AR=ppc_405-ar +export AS=ppc_405-as +export LD=ppc_405-ld +export RANLIB=ppc_405-ranlib +export CC=ppc_405-gcc +export NM=ppc_405-nm + +./configure --target=powerpc-hardhat-linux + --host=powerpc-hardhat-linux + --build=i586-pc-linux-gnu + --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local + --exec-prefix=/usr/local +``` + +You may also need to provide a parameter like `--with-random=/dev/urandom` to +configure as it cannot detect the presence of a random number generating +device for a target system. The `--prefix` parameter specifies where curl +will be installed. If `configure` completes successfully, do `make` and `make +install` as usual. + +In some cases, you may be able to simplify the above commands to as little as: + + ./configure --host=ARCH-OS + +# REDUCING SIZE + +There are a number of configure options that can be used to reduce the size of +libcurl for embedded applications where binary size is an important factor. +First, be sure to set the `CFLAGS` variable when configuring with any relevant +compiler optimization flags to reduce the size of the binary. For gcc, this +would mean at minimum the -Os option, and potentially the `-march=X`, +`-mdynamic-no-pic` and `-flto` options as well, e.g. + + ./configure CFLAGS='-Os' LDFLAGS='-Wl,-Bsymbolic'... + +Note that newer compilers often produce smaller code than older versions +due to improved optimization. + +Be sure to specify as many `--disable-` and `--without-` flags on the +configure command-line as you can to disable all the libcurl features that you +know your application is not going to need. Besides specifying the +`--disable-PROTOCOL` flags for all the types of URLs your application will not +use, here are some other flags that can reduce the size of the library by +disabling support for some feature: + + - `--disable-alt-svc` (HTTP Alt-Svc) + - `--disable-ares` (the C-ARES DNS library) + - `--disable-cookies` (HTTP cookies) + - `--disable-basic-auth` (cryptographic authentication) + - `--disable-bearer-auth` (cryptographic authentication) + - `--disable-digest-auth` (cryptographic authentication) + - `--disable-kerberos-auth` (cryptographic authentication) + - `--disable-negotiate-auth` (cryptographic authentication) + - `--disable-aws` (cryptographic authentication) + - `--disable-dateparse` (date parsing for time conditionals) + - `--disable-dnsshuffle` (internal server load spreading) + - `--disable-doh` (DNS-over-HTTP) + - `--disable-get-easy-options` (lookup easy options at runtime) + - `--disable-hsts` (HTTP Strict Transport Security) + - `--disable-http-auth` (all HTTP authentication) + - `--disable-ipv6` (IPv6) + - `--disable-libcurl-option` (--libcurl C code generation support) + - `--disable-manual` (built-in documentation) + - `--disable-netrc` (.netrc file) + - `--disable-ntlm-wb` (NTLM WinBind) + - `--disable-progress-meter` (graphical progress meter in library) + - `--disable-proxy` (HTTP and SOCKS proxies) + - `--disable-pthreads` (multi-threading) + - `--disable-socketpair` (socketpair for asynchronous name resolving) + - `--disable-threaded-resolver` (threaded name resolver) + - `--disable-tls-srp` (Secure Remote Password authentication for TLS) + - `--disable-unix-sockets` (UNIX sockets) + - `--disable-verbose` (eliminates debugging strings and error code strings) + - `--disable-versioned-symbols` (versioned symbols) + - `--enable-symbol-hiding` (eliminates unneeded symbols in the shared library) + - `--without-brotli` (Brotli on-the-fly decompression) + - `--without-libpsl` (Public Suffix List in cookies) + - `--without-nghttp2` (HTTP/2 using nghttp2) + - `--without-ngtcp2` (HTTP/2 using ngtcp2) + - `--without-zstd` (Zstd on-the-fly decompression) + - `--without-libidn2` (internationalized domain names) + - `--without-librtmp` (RTMP) + - `--without-ssl` (SSL/TLS) + - `--without-zlib` (on-the-fly decompression) + +The GNU compiler and linker have a number of options that can reduce the +size of the libcurl dynamic libraries on some platforms even further. +Specify them by providing appropriate `CFLAGS` and `LDFLAGS` variables on +the configure command-line, e.g. + + CFLAGS="-Os -ffunction-sections -fdata-sections + -fno-unwind-tables -fno-asynchronous-unwind-tables -flto" + LDFLAGS="-Wl,-s -Wl,-Bsymbolic -Wl,--gc-sections" + +Be sure also to strip debugging symbols from your binaries after compiling +using 'strip' (or the appropriate variant if cross-compiling). If space is +really tight, you may be able to remove some unneeded sections of the shared +library using the -R option to objcopy (e.g. the .comment section). + +Using these techniques it is possible to create a basic HTTP-only libcurl +shared library for i386 Linux platforms that is only 133 KiB in size +(as of libcurl version 7.80.0, using gcc 11.2.0). + +You may find that statically linking libcurl to your application will result +in a lower total size than dynamically linking. + +Note that the curl test harness can detect the use of some, but not all, of +the `--disable` statements suggested above. Use will cause tests relying on +those features to fail. The test harness can be manually forced to skip the +relevant tests by specifying certain key words on the `runtests.pl` command +line. Following is a list of appropriate key words for those configure options +that are not automatically detected: + + - `--disable-cookies` !cookies + - `--disable-dateparse` !RETRY-AFTER !`CURLOPT_TIMECONDITION` !`CURLINFO_FILETIME` !`If-Modified-Since` !`curl_getdate` !`-z` + - `--disable-libcurl-option` !`--libcurl` + - `--disable-verbose` !verbose\ logs + +# Ports + +This is a probably incomplete list of known CPU architectures and operating +systems that curl has been compiled for.

For example: + \\?\c:\longpath. + + See https://github.com/curl/curl/issues/8361 + +5.14 Windows Unicode builds use homedir in current locale + + The Windows Unicode builds of curl use the current locale, but expect Unicode + UTF-8 encoded paths for internal use such as open, access and stat. The user's + home directory is retrieved via curl_getenv in the current locale and not as + UTF-8 encoded Unicode. + + See https://github.com/curl/curl/pull/7252 and + https://github.com/curl/curl/pull/7281 + +6.

See ticket #5601 at https://krbdev.mit.edu/rt/ + +6.3 NTLM in system context uses wrong name + + NTLM authentication using SSPI (on Windows) when (lib)curl is running in + "system context" will make it use wrong(?) user name - at least when compared + to what winhttp does.

FTP + +7.3 FTP with NOBODY and FAILONERROR + + It seems sensible to be able to use CURLOPT_NOBODY and CURLOPT_FAILONERROR + with FTP to detect if a file exists or not, but it is not working: + https://curl.se/mail/lib-2008-07/0295.html + +7.4 FTP with ACCT + + When doing an operation over FTP that requires the ACCT command (but not when + logging in), the operation will fail since libcurl does not detect this and + thus fails to issue the correct command: + https://curl.se/bug/view.cgi?id=635 + +7.11 FTPS upload data loss with TLS 1.3 + + During FTPS upload curl does not attempt to read TLS handshake messages sent + after the initial handshake. OpenSSL servers running TLS 1.3 may send such a + message. When curl closes the upload connection if unread data has been + received (such as a TLS handshake message) then the TCP protocol sends an + RST to the server, which may cause the server to discard or truncate the + upload if it has not read all sent data yet, and then return an error to curl + on the control channel connection. + + Since 7.78.0 this is mostly fixed. curl will do a single read before closing + TLS connections (which causes the TLS library to read handshake messages), + however there is still possibility of an RST if more messages need to be read + or a message arrives after the read but before close (network race condition). + + https://github.com/curl/curl/issues/6149 + +7.12 FTPS directory listing hangs on Windows with Schannel + + https://github.com/curl/curl/issues/9161 + +9. SFTP and SCP + +9.1 SFTP does not do CURLOPT_POSTQUOTE correct + + When libcurl sends CURLOPT_POSTQUOTE commands when connected to a SFTP server + using the multi interface, the commands are not being sent correctly and + instead the connection is "cancelled" (the operation is considered done) + prematurely.

SOCKS + +10.3 FTPS over SOCKS + + libcurl does not support FTPS over a SOCKS proxy. + + +11. Internals + +11.2 error buffer not set if connection to multiple addresses fails + + If you ask libcurl to resolve a hostname like example.com to IPv6 addresses + only.

LDAP + +12.1 OpenLDAP hangs after returning results + + By configuration defaults, OpenLDAP automatically chase referrals on + secondary socket descriptors. The OpenLDAP backend is asynchronous and thus + should monitor all socket descriptors involved. Currently, these secondary + descriptors are not monitored, causing OpenLDAP library to never receive + data from them. + + As a temporary workaround, disable referrals chasing by configuration. + + The fix is not easy: proper automatic referrals chasing requires a + synchronous bind callback and monitoring an arbitrary number of socket + descriptors for a single easy handle (currently limited to 5). + + Generic LDAP is synchronous: OK. + + See https://github.com/curl/curl/issues/622 and + https://curl.se/mail/lib-2016-01/0101.html + +12.2 LDAP on Windows does authentication wrong? + + https://github.com/curl/curl/issues/3116 + +12.3 LDAP on Windows does not work + + A simple curl command line getting "ldap://ldap.forumsys.com" returns an + error that says "no memory" ! + + https://github.com/curl/curl/issues/4261 + +12.4 LDAPS requests to ActiveDirectory server hang + + https://github.com/curl/curl/issues/9580 + +13. TCP/IP + +13.2 Trying local ports fails on Windows + + This makes '--local-port [range]' to not work since curl cannot properly + detect if a port is already in use, so it will try the first port, use that and + then subsequently fail anyway if that was actually in use. + + https://github.com/curl/curl/issues/8112 + +15.

About the lists + + 1.1 Mailing Lists + + The mailing lists we have are all listed and described at + https://curl.se/mail/ + + Each mailing list is targeted to a specific set of users and subjects, + please use the one or the ones that suit you the most. + + Each mailing list has hundreds up to thousands of readers, meaning that each + mail sent will be received and read by a large number of people. People + from various cultures, regions, religions and continents. + + 1.2 Netiquette + + Netiquette is a common term for how to behave on the Internet. Of course, in + each particular group and subculture there will be differences in what is + acceptable and what is considered good manners. + + This document outlines what we in the curl project consider to be good + etiquette, and primarily this focus on how to behave on and how to use our + mailing lists. + + 1.3 Do Not Mail a Single Individual + + Many people send one question to one person. One person gets many mails, and + there is only one person who can give you a reply. The question may be + something that other people would also like to ask. These other people have + no way to read the reply, but to ask the one person the question. The one + person consequently gets overloaded with mail. + + If you really want to contact an individual and perhaps pay for his or her + services, by all means go ahead, but if it's just another curl question, + take it to a suitable list instead. + + 1.4 Subscription Required + + All curl mailing lists require that you are subscribed to allow a mail to go + through to all the subscribers. + + If you post without being subscribed (or from a different mail address than + the one you are subscribed with), your mail will simply be silently + discarded. You have to subscribe first, then post. + + The reason for this unfortunate and strict subscription policy is of course + to stop spam from pestering the lists. + + 1.5 Moderation of new posters + + Several of the curl mailing lists automatically make all posts from new + subscribers be moderated. This means that after you have subscribed and + sent your first mail to a list, that mail will not be let through to the + list until a mailing list administrator has verified that it is OK and + permits it to get posted. + + Once a first post has been made that proves the sender is actually talking + about curl-related subjects, the moderation "flag" will be switched off and + future posts will go through without being moderated. + + The reason for this moderation policy is that we do suffer from spammers who + actually subscribe and send spam to our lists. + + 1.6 Handling trolls and spam + + Despite our good intentions and hard work to keep spam off the lists and to + maintain a friendly and positive atmosphere, there will be times when spam + and or trolls get through. + + Troll - "someone who posts inflammatory, extraneous, or off-topic messages + in an online community" + + Spam - "use of electronic messaging systems to send unsolicited bulk + messages" + + No matter what, we NEVER EVER respond to trolls or spammers on the list. If + you believe the list admin should do something in particular, contact them + off-list. The subject will be taken care of as much as possible to prevent + repeated offenses, but responding on the list to such messages never leads to + anything good and only puts the light even more on the offender: which was + the entire purpose of it getting sent to the list in the first place. + + Do not feed the trolls. + + 1.7 How to unsubscribe + + You can unsubscribe the same way you subscribed in the first place. You go + to the page for the particular mailing list you are subscribed to and you enter + your email address and password and press the unsubscribe button. + + Also, the instructions to unsubscribe are included in the headers of every + mail that is sent out to all curl related mailing lists and there is a footer + in each mail that links to the "admin" page on which you can unsubscribe and + change other options. + + You NEVER EVER email the mailing list requesting someone else to take you off + the list. + + 1.8 I posted, now what? + + If you are not subscribed with the same email address that you used to send + the email, your post will just be silently discarded. + + If you posted for the first time to the mailing list, you first need to wait + for an administrator to allow your email to go through (moderated). This + normally happens quickly but in case we are asleep, you may have to wait a + few hours. + + Once your email goes through it is sent out to several hundred or even + thousands of recipients. Your email may cover an area that not that many + people know about or are interested in. Or possibly the person who knows + about it is on vacation or under a heavy work load right now. You may have + to wait for a response and you should not expect to get a response at all. + Ideally, you get an answer within a couple of days. + + You do yourself and all of us a service when you include as many details as + possible already in your first email. Mention your operating system and + environment. Tell us which curl version you are using and tell us what you + did, what happened and what you expected would happen. Preferably, show us + what you did with details enough to allow others to help point out the + problem or repeat the steps in their locations. + + Failing to include details will only delay responses and make people respond + and ask for more details and you will have to send a follow-up email that + includes them. + + Expect the responses to primarily help YOU debug the issue, or ask YOU + questions that can lead you or others towards a solution or explanation to + whatever you experience. + + If you are a repeat offender to the guidelines outlined in this document, + chances are that people will ignore you at will and your chances to get + responses in the future will greatly diminish. + + 1.9 Your emails are public + + Your email, its contents and all its headers and the details in those + headers will be received by every subscriber of the mailing list that you + send your email to. + + Your email as sent to a curl mailing list will end up in mail archives, on + the curl website and elsewhere, for others to see and read. Today and in + the future. In addition to the archives, the mail is sent out to thousands + of individuals. There is no way to undo a sent email. + + When sending emails to a curl mailing list, do not include sensitive + information such as user names and passwords; use fake ones, temporary ones + or just remove them completely from the mail. Note that this includes base64 + encoded HTTP Basic auth headers. + + This public nature of the curl mailing lists makes automatically inserted mail + footers about mails being "private" or "only meant for the recipient" or + similar even more silly than usual. Because they are absolutely not private + when sent to a public mailing list. + + +2. Sending mail + + 2.1 Reply or New Mail + + Please do not reply to an existing message as a short-cut to post a message + to the lists. + + Many mail programs and web archivers use information within mails to keep + them together as "threads", as collections of posts that discuss a certain + subject. If you do not intend to reply on the same or similar subject, do not + just hit reply on an existing mail and change the subject, create a new mail. + + 2.2 Reply to the List + + When replying to a message from the list, make sure that you do "group + reply" or "reply to all", and not just reply to the author of the single + mail you reply to. + + We are actively discouraging replying back to the single person by setting + the Reply-To: field in outgoing mails back to the mailing list address, + making it harder for people to mail the author directly, if only by mistake. + + 2.3 Use a Sensible Subject + + Please use a subject of the mail that makes sense and that is related to the + contents of your mail. It makes it a lot easier to find your mail afterwards + and it makes it easier to track mail threads and topics. + + 2.4 Do Not Top-Post + + If you reply to a message, do not use top-posting. Top-posting is when you + write the new text at the top of a mail and you insert the previous quoted + mail conversation below. It forces users to read the mail in a backwards + order to properly understand it. + + This is why top posting is so bad (in top posting order): + + A: Because it messes up the order in which people normally read text. + Q: Why is top-posting such a bad thing? + A: Top-posting. + Q: What is the most annoying thing in email? + + Apart from the screwed up read order (especially when mixed together in a + thread when someone responds using the mandated bottom-posting style), it + also makes it impossible to quote only parts of the original mail. + + When you reply to a mail. You let the mail client insert the previous mail + quoted. Then you put the cursor on the first line of the mail and you move + down through the mail, deleting all parts of the quotes that do not add + context for your comments. When you want to add a comment you do so, inline, + right after the quotes that relate to your comment. Then you continue + downwards again. + + When most of the quotes have been removed and you have added your own words, + you are done. + + 2.5 HTML is not for mails + + Please switch off those HTML encoded messages. You can mail all those funny + mails to your friends. We speak plain text mails. + + 2.6 Quoting + + Quote as little as possible. Just enough to provide the context you cannot + leave out. A lengthy description can be found here: + + https://www.netmeister.org/news/learn2quote.html + + 2.7 Digest + + We allow subscribers to subscribe to the "digest" version of the mailing + lists. A digest is a collection of mails lumped together in one single mail. + + Should you decide to reply to a mail sent out as a digest, there are two + things you MUST consider if you really really cannot subscribe normally + instead: + + Cut off all mails and chatter that is not related to the mail you want to + reply to. + + Change the subject name to something sensible and related to the subject, + preferably even the actual subject of the single mail you wanted to reply to + + 2.8 Please Tell Us How You Solved The Problem + + Many people mail questions to the list, people spend some of their time and + make an effort in providing good answers to these questions. + + If you are the one who asks, please consider responding once more in case + one of the hints was what solved your problems. The guys who write answers + feel good to know that they provided a good answer and that you fixed the + problem. Far too often, the person who asked the question is never heard from + again, and we never get to know if they are gone because the problem was + solved or perhaps because the problem was unsolvable. + + Getting the solution posted also helps other users that experience the same + problem(s). They get to see (possibly in the web archives) that the + suggested fixes actually have helped at least one person. diff --git a/src/ext/curl/docs/MQTT.md b/src/ext/curl/docs/MQTT.md new file mode 100644 index 00000000..660ff29a --- /dev/null +++ b/src/ext/curl/docs/MQTT.md @@ -0,0 +1,27 @@ +# MQTT in curl + +## Usage + +A plain "GET" subscribes to the topic and prints all published messages. +Doing a "POST" publishes the post data to the topic and exits. + +Example subscribe: + + curl mqtt://host.home/bedroom/temp + +Example publish: + + curl -d 75 mqtt://host.home/bedroom/dimmer + +## What does curl deliver as a response to a subscribe + +It outputs two bytes topic length (MSB | LSB), the topic followed by the +payload. + +## Caveats + +Remaining limitations: + - Only QoS level 0 is implemented for publish + - No way to set retain flag for publish + - No TLS (mqtts) support + - Naive EAGAIN handling will not handle split messages diff --git a/src/ext/curl/docs/Makefile b/src/ext/curl/docs/Makefile new file mode 100644 index 00000000..9aba7d74 --- /dev/null +++ b/src/ext/curl/docs/Makefile @@ -0,0 +1,951 @@ +# Makefile.in generated by automake 1.16.5 from Makefile.am. +# docs/Makefile.

b/src/ext/curl/docs/NEW-PROTOCOL.md @@ -0,0 +1,110 @@ +# Adding a new protocol? + +Every once in a while, someone comes up with the idea of adding support for yet +another protocol to curl. After all, curl already supports 25 something +protocols and it is the Internet transfer machine for the world. + +In the curl project we love protocols and we love supporting many protocols +and doing it well. + +How do you proceed to add a new protocol and what are the requirements? + +## No fixed set of requirements + +This document is an attempt to describe things to consider. There is no +checklist of the twenty-seven things you need to cross off. We view the entire +effort as a whole and then judge if it seems to be the right thing - for +now. The more things that look right, fit our patterns and are done in ways +that align with our thinking, the better are the chances that we will agree +that supporting this protocol is a grand idea. + +## Mutual benefit is preferred + +curl is not here for your protocol. Your protocol is not here for curl. The +best cooperation and end result occur when all involved parties mutually see +and agree that supporting this protocol in curl would be good for everyone. +Heck, for the world. + +Consider "selling us" the idea that we need an implementation merged in curl, +to be fairly important. *Why* do we want curl to support this new protocol? + +## Protocol requirements + +### Client-side + +The protocol implementation is for a client's side of a "communication +session". + +### Transfer oriented + +The protocol itself should be focused on *transfers*. Be it uploads or +downloads or both. It should at least be possible to view the transfers as +such, like we can view reading emails over POP3 as a download and sending +emails over SMTP as an upload. + +If you cannot even shoehorn the protocol into a transfer focused view, then +you are up for a tough argument. + +### URL + +There should be a documented URL format. If there is an RFC for it there is no +question about it but the syntax does not have to be a published RFC. It could +be enough if it is already in use by other implementations. + +If you make up the syntax just in order to be able to propose it to curl, then +you are in a bad place. URLs are designed and defined for interoperability. +There should at least be a good chance that other clients and servers can be +implemented supporting the same URL syntax and work the same or similar way. + +URLs work on registered 'schemes'. There is a register of [all officially +recognized +schemes](https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml). If +your protocol is not in there, is it really a protocol we want? + +### Wide and public use + +The protocol shall already be used or have an expectation of getting used +widely. Experimental protocols are better off worked on in experiments first, +to prove themselves before they are adopted by curl. + +## Code + +Of course the code needs to be written, provided, licensed agreeably and it +should follow our code guidelines and review comments have to be dealt with. +If the implementation needs third party code, that third party code should not +have noticeably lesser standards than the curl project itself. + +## Tests + +As much of the protocol implementation as possible needs to be verified by +curl test cases. We must have the implementation get tested by CI jobs, +torture tests and more. + +We have experienced many times in the past how new implementations were brought +to curl and immediately once the code had been merged, the originator vanished +from the face of the earth. That is fine, but we need to take the necessary +precautions so when it happens we are still fine. + +Our test infrastructure is powerful enough to test just about every possible +protocol - but it might require a bit of an effort to make it happen. + +## Documentation + +We cannot assume that users are particularly familiar with details and +peculiarities of the protocol. It needs documentation. + +Maybe it even needs some internal documentation so that the developers who +will try to debug something five years from now can figure out functionality a +little easier! + +The protocol specification itself should be freely available without requiring +a non-disclosure agreement or similar. + +## Do not compare + +We are constantly raising the bar and we are constantly improving the +project.

Scroll down for details on how the OS-native engines handle SSL +certificates. If you are not sure, then run "curl -V" and read the results. If +the version string says `Schannel` in it, then it was built with Schannel +support. + +It is about trust +----------------- + +This system is about trust. In your local CA certificate store you have certs +from *trusted* Certificate Authorities that you then can use to verify that +the server certificates you see are valid. They are signed by one of the +certificate authorities you trust. + +Which certificate authorities do you trust? You can decide to trust the same +set of companies your operating system trusts, or the set one of the known +browsers trust. That is basically trust via someone else you trust. You should +just be aware that modern operating systems and browsers are setup to trust +*hundreds* of companies and in recent years several certificate authorities +have been found untrustworthy. + +Certificate Verification +------------------------ + +libcurl performs peer SSL certificate verification by default. This is done +by using a CA certificate store that the SSL library can use to make sure the +peer's server certificate is valid. + +If you communicate with HTTPS, FTPS or other TLS-using servers using +certificates in the CA store, you can be sure that the remote server really is +the one it claims to be. + +If the remote server uses a self-signed certificate, if you do not install a CA +cert store, if the server uses a certificate signed by a CA that is not +included in the store you use or if the remote host is an impostor +impersonating your favorite site, and you want to transfer files from this +server, do one of the following: + + 1. Tell libcurl to *not* verify the peer. With libcurl you disable this with + `curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);` + + With the curl command line tool, you disable this with `-k`/`--insecure`. + + 2. Get a CA certificate that can verify the remote server and use the proper + option to point out this CA cert for verification when connecting. For + libcurl hackers: `curl_easy_setopt(curl, CURLOPT_CAINFO, cacert);` + + With the curl command line tool: `--cacert [file]` + + 3. Add the CA cert for your server to the existing default CA certificate + store. The default CA certificate store can be changed at compile time with + the following configure options: + + `--with-ca-bundle=FILE`: use the specified file as the CA certificate + store. CA certificates need to be concatenated in PEM format into this + file. + + `--with-ca-path=PATH`: use the specified path as CA certificate store. CA + certificates need to be stored as individual PEM files in this directory. + You may need to run c_rehash after adding files there. + + If neither of the two options is specified, configure will try to + auto-detect a setting. It's also possible to explicitly not set any + default store but rely on the built in default the crypto library may + provide instead. You can achieve that by passing both + `--without-ca-bundle` and `--without-ca-path` to the configure script. + + If you use Internet Explorer, this is one way to get extract the CA cert + for a particular server: + + - View the certificate by double-clicking the padlock + - Find out where the CA certificate is kept (Certificate> + Authority Information Access>URL) + - Get a copy of the crt file using curl + - Convert it from crt to PEM using the OpenSSL tool: + `openssl x509 -inform DES -in yourdownloaded.crt -out outcert.pem -text` + - Add the `outcert.pem` to the CA certificate store or use it stand-alone + as described below. + + If you use the `openssl` tool, this is one way to get extract the CA cert + for a particular server: + + - `openssl s_client -showcerts -servername server -connect server:443 > cacert.pem` + - type "quit", followed by the "ENTER" key + - The certificate will have "BEGIN CERTIFICATE" and "END CERTIFICATE" + markers. + - If you want to see the data in the certificate, you can do: `openssl + x509 -inform PEM -in certfile -text -out certdata` where `certfile` is + the cert you extracted from logfile. Look in `certdata`. + - If you want to trust the certificate, you can add it to your CA + certificate store or use it stand-alone as described. Just remember that + the security is no better than the way you obtained the certificate. + + 4. If you are using the curl command line tool and the TLS backend is not + Schannel then you can specify your own CA cert file by setting the + environment variable `CURL_CA_BUNDLE` to the path of your choice. + + If you are using the curl command line tool on Windows, curl will search + for a CA cert file named "curl-ca-bundle.crt" in these directories and in + this order: + 1. application's directory + 2. current working directory + 3.

These are the same +certificates that appear in the Internet Options control panel (under Windows) +or Keychain Access application (under OS X). Any custom security rules for +certificates will be honored. + +Schannel will run CRL checks on certificates unless peer verification is +disabled. Secure Transport on iOS will run OCSP checks on certificates unless +peer verification is disabled. Secure Transport on OS X will run either OCSP +or CRL checks on certificates if those features are enabled, and this behavior +can be adjusted in the preferences of Keychain Access. + +HTTPS proxy +----------- + +Since version 7.52.0, curl can do HTTPS to the proxy separately from the +connection to the server. This TLS connection is handled separately from the +server connection so instead of `--insecure` and `--cacert` to control the +certificate verification, you use `--proxy-insecure` and `--proxy-cacert`. +With these options, you make sure that the TLS connection and the trust of the +proxy can be kept totally separate from the TLS connection to the server. diff --git a/src/ext/curl/docs/THANKS b/src/ext/curl/docs/THANKS new file mode 100644 index 00000000..eee2ec51 --- /dev/null +++ b/src/ext/curl/docs/THANKS @@ -0,0 +1,3083 @@ + This project has been alive for many years.

Note that Windows + does not have res_init() or an alternative. + + https://github.com/curl/curl/issues/2251 + +1.13 c-ares and CURLOPT_OPENSOCKETFUNCTION + + curl will create most sockets via the CURLOPT_OPENSOCKETFUNCTION callback and + close them with the CURLOPT_CLOSESOCKETFUNCTION callback. However, c-ares + does not use those functions and instead opens and closes the sockets + itself. This means that when curl passes the c-ares socket to the + CURLMOPT_SOCKETFUNCTION it is not owned by the application like other sockets. + + See https://github.com/curl/curl/issues/2734 + +1.15 Monitor connections in the connection pool + + libcurl's connection cache or pool holds a number of open connections for the + purpose of possible subsequent connection reuse. It may contain a few up to a + significant amount of connections. Currently, libcurl leaves all connections + as they are and first when a connection is iterated over for matching or + reuse purpose it is verified that it is still alive. + + Those connections may get closed by the server side for idleness or they may + get an HTTP/2 ping from the peer to verify that they are still alive. By + adding monitoring of the connections while in the pool, libcurl can detect + dead connections (and close them) better and earlier, and it can handle + HTTP/2 pings to keep such ones alive even when not actively doing transfers + on them. + +1.16 Try to URL encode given URL + + Given a URL that for example contains spaces, libcurl could have an option + that would try somewhat harder than it does now and convert spaces to %20 and + perhaps URL encoded byte values over 128 etc (basically do what the redirect + following code already does). + + https://github.com/curl/curl/issues/514 + +1.17 Add support for IRIs + + IRIs (RFC 3987) allow localized, non-ascii, names in the URL. To properly + support this, curl/libcurl would need to translate/encode the given input + from the input string encoding into percent encoded output "over the wire". + + To make that work smoothly for curl users even on Windows, curl would + probably need to be able to convert from several input encodings. + +1.18 try next proxy if one does not work + + Allow an application to specify a list of proxies to try, and failing to + connect to the first go on and try the next instead until the list is + exhausted. Browsers support this feature at least when they specify proxies + using PACs. + + https://github.com/curl/curl/issues/896 + +1.19 provide timing info for each redirect + + curl and libcurl provide timing information via a set of different + time-stamps (CURLINFO_*_TIME).

For + example the user's debug function callback is not inherited because it would + be unexpected for internal handles (ie DoH handles) to be passed to that + callback. + + If an option is not inherited then it is not possible to set it separately + for DoH without a DoH-specific option. For example: + CURLOPT_DOH_SSL_VERIFYHOST, CURLOPT_DOH_SSL_VERIFYPEER and + CURLOPT_DOH_SSL_VERIFYSTATUS. + + See https://github.com/curl/curl/issues/6605 + +2. libcurl - multi interface + +2.1 More non-blocking + + Make sure we do not ever loop because of non-blocking sockets returning + EWOULDBLOCK or similar. Blocking cases include: + + - Name resolves on non-windows unless c-ares or the threaded resolver is used. + + - The threaded resolver may block on cleanup: + https://github.com/curl/curl/issues/4852 + + - file:// transfers + + - TELNET transfers + + - GSSAPI authentication for FTP transfers + + - The "DONE" operation (post transfer protocol-specific actions) for the + protocols SFTP, SMTP, FTP. Fixing multi_done() for this is a worthy task. + + - curl_multi_remove_handle for any of the above. See section 2.3. + +2.2 Better support for same name resolves + + If a name resolve has been initiated for name NN and a second easy handle + wants to resolve that name as well, make it wait for the first resolve to end + up in the cache instead of doing a second separate resolve. This is + especially needed when adding many simultaneous handles using the same host + name when the DNS resolver can get flooded. + +2.3 Non-blocking curl_multi_remove_handle() + + The multi interface has a few API calls that assume a blocking behavior, like + add_handle() and remove_handle() which limits what we can do internally. The + multi API need to be moved even more into a single function that "drives" + everything in a non-blocking manner and signals when something is done. A + remove or add would then only ask for the action to get started and then + multi_perform() etc still be called until the add/remove is completed. + +2.4 Split connect and authentication process + + The multi interface treats the authentication process as part of the connect + phase. As such any failures during authentication will not trigger the relevant + QUIT or LOGOFF for protocols such as IMAP, POP3 and SMTP. + +2.5 Edge-triggered sockets should work + + The multi_socket API should work with edge-triggered socket events. One of + the internal actions that need to be improved for this to work perfectly is + the 'maxloops' handling in transfer.c:readwrite_data(). + +2.6 multi upkeep + + In libcurl 7.62.0 we introduced curl_easy_upkeep. It unfortunately only works + on easy handles. We should introduces a version of that for the multi handle, + and also consider doing "upkeep" automatically on connections in the + connection pool when the multi handle is in used. + + See https://github.com/curl/curl/issues/3199 + +2.7 Virtual external sockets + + libcurl performs operations on the given file descriptor that presumes it is + a socket and an application cannot replace them at the moment.

Currently it tries ::1, but it should also try 127.0.0.1. + + See https://github.com/curl/curl/issues/1508 + +5. HTTP + +5.1 Provide the error body from a CONNECT response + + When curl receives a body response from a CONNECT request to a proxy, it will + always just read and ignore it.

Through some other means? + + See https://github.com/curl/curl/issues/9513 + +5.2 Obey Retry-After in redirects + + The Retry-After is said to dicate "the minimum time that the user agent is + asked to wait before issuing the redirected request" and libcurl does not + obey this. + + See https://github.com/curl/curl/issues/11447 + +5.3 Rearrange request header order + + Server implementers often make an effort to detect browser and to reject + clients it can detect to not match. One of the last details we cannot yet + control in libcurl's HTTP requests, which also can be exploited to detect + that libcurl is in fact used even when it tries to impersonate a browser, is + the order of the request headers. I propose that we introduce a new option in + which you give headers a value, and then when the HTTP request is built it + sorts the headers based on that number. We could then have internally created + headers use a default value so only headers that need to be moved have to be + specified. + +5.4 Allow SAN names in HTTP/2 server push + + curl only allows HTTP/2 push promise if the provided :authority header value + exactly matches the host name given in the URL. It could be extended to allow + any name that would match the Subject Alternative Names in the server's TLS + certificate. + + See https://github.com/curl/curl/pull/3581 + +5.5 auth= in URLs + + Add the ability to specify the preferred authentication mechanism to use by + using ;auth= in the login part of the URL. + + For example: + + http://test:pass;auth=NTLM@example.com would be equivalent to specifying + --user test:pass;auth=NTLM or --user test:pass --ntlm from the command line. + + Additionally this should be implemented for proxy base URLs as well. + +5.6 alt-svc should fallback if alt-svc does not work + + The alt-svc: header provides a set of alternative services for curl to use + instead of the original. If the first attempted one fails, it should try the + next etc and if all alternatives fail go back to the original. + + See https://github.com/curl/curl/issues/4908 + +5.7 Require HTTP version X or higher + + curl and libcurl provide options for trying higher HTTP versions (for example + HTTP/2) but then still allows the server to pick version 1.1.

To be able to automatically + extract information from the web, to fake users, to post or upload data to + web servers are all important tasks today. + + Curl is a command line tool for doing all sorts of URL manipulations and + transfers, but this particular document will focus on how to use it when + doing HTTP requests for fun and profit. This documents assumes that you know + how to invoke `curl --help` or `curl --manual` to get basic information about + it. + + Curl is not written to do everything for you. It makes the requests, it gets + the data, it sends data and it retrieves the information. You probably need + to glue everything together using some kind of script language or repeated + manual invokes. + +## The HTTP Protocol + + HTTP is the protocol used to fetch data from web servers. It is a simple + protocol that is built upon TCP/IP. The protocol also allows information to + get sent to the server from the client using a few different methods, as will + be shown here. + + HTTP is plain ASCII text lines being sent by the client to a server to + request a particular action, and then the server replies a few text lines + before the actual requested content is sent to the client. + + The client, curl, sends an HTTP request. The request contains a method (like + GET, POST, HEAD etc), a number of request headers and sometimes a request + body. The HTTP server responds with a status line (indicating if things went + well), response headers and most often also a response body. The "body" part + is the plain data you requested, like the actual HTML or the image etc. + +## See the Protocol + + Using curl's option [`--verbose`](https://curl.se/docs/manpage.html#-v) + (`-v` as a short option) will display what kind of commands curl sends to the + server, as well as a few other informational texts. + + `--verbose` is the single most useful option when it comes to debug or even + understand the curl<->server interaction. + + Sometimes even `--verbose` is not enough. Then + [`--trace`](https://curl.se/docs/manpage.html#-trace) and + [`--trace-ascii`](https://curl.se/docs/manpage.html#--trace-ascii) + offer even more details as they show **everything** curl sends and + receives. Use it like this: + + curl --trace-ascii debugdump.txt http://www.example.com/ + +## See the Timing + + Many times you may wonder what exactly is taking all the time, or you just + want to know the amount of milliseconds between two points in a transfer. For + those, and other similar situations, the + [`--trace-time`](https://curl.se/docs/manpage.html#--trace-time) option + is what you need. It will prepend the time to each trace output line: + + curl --trace-ascii d.txt --trace-time http://example.com/ + +## See which Transfer + + When doing parallel transfers, it is relevant to see which transfer is + doing what. When response headers are received (and logged) you need to + know which transfer these are for. + [`--trace-ids`](https://curl.se/docs/manpage.html#--trace-ids) option + is what you need. It will prepend the transfer and connection identifier + to each trace output line: + + curl --trace-ascii d.txt --trace-ids http://example.com/ + +## See the Response + + By default curl sends the response to stdout. You need to redirect it + somewhere to avoid that, most often that is done with `-o` or `-O`. + +# URL + +## Spec + + The Uniform Resource Locator format is how you specify the address of a + particular resource on the Internet. You know these, you have seen URLs like + https://curl.se or https://example.com a million times. RFC 3986 is the + canonical spec. The formal name is not URL, it is **URI**. + +## Host + + The hostname is usually resolved using DNS or your /etc/hosts file to an IP + address and that is what curl will communicate with. Alternatively you specify + the IP address directly in the URL instead of a name. + + For development and other trying out situations, you can point to a different + IP address for a hostname than what would otherwise be used, by using curl's + [`--resolve`](https://curl.se/docs/manpage.html#--resolve) option: + + curl --resolve www.example.org:80:127.0.0.1 http://www.example.org/ + +## Port number + + Each protocol curl supports operates on a default port number, be it over TCP + or in some cases UDP. Normally you do not have to take that into + consideration, but at times you run test servers on other ports or + similar. Then you can specify the port number in the URL with a colon and a + number immediately following the hostname. Like when doing HTTP to port + 1234: + + curl http://www.example.org:1234/ + + The port number you specify in the URL is the number that the server uses to + offer its services. Sometimes you may use a proxy, and then you may + need to specify that proxy's port number separately from what curl needs to + connect to the server. Like when using an HTTP proxy on port 4321: + + curl --proxy http://proxy.example.org:4321 http://remote.example.org/ + +## User name and password + + Some services are setup to require HTTP authentication and then you need to + provide name and password which is then transferred to the remote site in + various ways depending on the exact authentication protocol used. + + You can opt to either insert the user and password in the URL or you can + provide them separately: + + curl http://user:password@example.org/ + + or + + curl -u user:password http://example.org/ + + You need to pay attention that this kind of HTTP authentication is not what + is usually done and requested by user-oriented websites these days. They tend + to use forms and cookies instead. + +## Path part + + The path part is just sent off to the server to request that it sends back + the associated response. The path is what is to the right side of the slash + that follows the hostname and possibly port number. + +# Fetch a page + +## GET + + The simplest and most common request/operation made using HTTP is to GET a + URL. The URL could itself refer to a webpage, an image or a file. The client + issues a GET request to the server and receives the document it asked for. + If you issue the command line + + curl https://curl.se + + you get a webpage returned in your terminal window. The entire HTML document + that that URL holds. + + All HTTP replies contain a set of response headers that are normally hidden, + use curl's [`--include`](https://curl.se/docs/manpage.html#-i) (`-i`) + option to display them as well as the rest of the document. + +## HEAD + + You can ask the remote server for ONLY the headers by using the + [`--head`](https://curl.se/docs/manpage.html#-I) (`-I`) option which + will make curl issue a HEAD request. In some special cases servers deny the + HEAD method while others still work, which is a particular kind of annoyance. + + The HEAD method is defined and made so that the server returns the headers + exactly the way it would do for a GET, but without a body. It means that you + may see a `Content-Length:` in the response headers, but there must not be an + actual body in the HEAD response. + +## Multiple URLs in a single command line + + A single curl command line may involve one or many URLs. The most common case + is probably to just use one, but you can specify any amount of URLs. Yes + any. No limits. You will then get requests repeated over and over for all the + given URLs. + + Example, send two GET requests: + + curl http://url1.example.com http://url2.example.com + + If you use [`--data`](https://curl.se/docs/manpage.html#-d) to POST to + the URL, using multiple URLs means that you send that same POST to all the + given URLs. + + Example, send two POSTs: + + curl --data name=curl http://url1.example.com http://url2.example.com + + +## Multiple HTTP methods in a single command line + + Sometimes you need to operate on several URLs in a single command line and do + different HTTP methods on each. For this, you will enjoy the + [`--next`](https://curl.se/docs/manpage.html#-:) option. It is basically + a separator that separates a bunch of options from the next. All the URLs + before `--next` will get the same method and will get all the POST data + merged into one. + + When curl reaches the `--next` on the command line, it will sort of reset the + method and the POST data and allow a new set. + + Perhaps this is best shown with a few examples. To send first a HEAD and then + a GET: + + curl -I http://example.com --next http://example.com + + To first send a POST and then a GET: + + curl -d score=10 http://example.com/post.cgi --next http://example.com/results.html + +# HTML forms + +## Forms explained + + Forms are the general way a website can present an HTML page with fields for + the user to enter data in, and then press some kind of 'OK' or 'Submit' + button to get that data sent to the server. The server then typically uses + the posted data to decide how to act. Like using the entered words to search + in a database, or to add the info in a bug tracking system, display the + entered address on a map or using the info as a login-prompt verifying that + the user is allowed to see what it is about to see. + + Of course there has to be some kind of program on the server end to receive + the data you send. You cannot just invent something out of the air. + +## GET + + A GET-form uses the method GET, as specified in HTML like: + +```html +
+ + +
+``` + + In your favorite browser, this form will appear with a text box to fill in + and a press-button labeled "OK". If you fill in '1905' and press the OK + button, your browser will then create a new URL to get for you. The URL will + get `junk.cgi?birthyear=1905&press=OK` appended to the path part of the + previous URL. + + If the original form was seen on the page `www.example.com/when/birth.html`, + the second page you will get will become + `www.example.com/when/junk.cgi?birthyear=1905&press=OK`. + + Most search engines work this way. + + To make curl do the GET form post for you, just enter the expected created + URL: + + curl "http://www.example.com/when/junk.cgi?birthyear=1905&press=OK" + +## POST + + The GET method makes all input field names get displayed in the URL field of + your browser. That is generally a good thing when you want to be able to + bookmark that page with your given data, but it is an obvious disadvantage if + you entered secret information in one of the fields or if there are a large + amount of fields creating a long and unreadable URL. + + The HTTP protocol then offers the POST method. This way the client sends the + data separated from the URL and thus you will not see any of it in the URL + address field. + + The form would look similar to the previous one: + +```html +
+ + +
+``` + + And to use curl to post this form with the same data filled in as before, we + could do it like: + + curl --data "birthyear=1905&press=%20OK%20" http://www.example.com/when/junk.cgi + + This kind of POST will use the Content-Type + `application/x-www-form-urlencoded` and is the most widely used POST kind. + + The data you send to the server MUST already be properly encoded, curl will + not do that for you. For example, if you want the data to contain a space, + you need to replace that space with `%20`, etc. Failing to comply with this will + most likely cause your data to be received wrongly and messed up. + + Recent curl versions can in fact url-encode POST data for you, like this: + + curl --data-urlencode "name=I am Daniel" http://www.example.com + + If you repeat `--data` several times on the command line, curl will + concatenate all the given data pieces - and put a `&` symbol between each + data segment. + +## File Upload POST + + Back in late 1995 they defined an additional way to post data over HTTP. It + is documented in the RFC 1867, why this method sometimes is referred to as + RFC 1867-posting. + + This method is mainly designed to better support file uploads. A form that + allows a user to upload a file could be written like this in HTML: + +
+ + +
+ + This clearly shows that the Content-Type about to be sent is + `multipart/form-data`. + + To post to a form like this with curl, you enter a command line like: + + curl --form upload=@localfilename --form press=OK [URL] + +## Hidden Fields + + A common way for HTML based applications to pass state information between + pages is to add hidden fields to the forms. Hidden fields are already filled + in, they are not displayed to the user and they get passed along just as all + the other fields. + + A similar example form with one visible field, one hidden field and one + submit button could look like: + +```html +

+``` + + To POST this with curl, you will not have to think about if the fields are + hidden or not. To curl they are all the same: + + curl --data "birthyear=1905&press=OK&person=daniel" [URL] + +## Figure Out What A POST Looks Like + + When you are about to fill in a form and send it to a server by using curl + instead of a browser, you are of course interested in sending a POST exactly + the way your browser does. + + An easy way to get to see this, is to save the HTML page with the form on + your local disk, modify the 'method' to a GET, and press the submit button + (you could also change the action URL if you want to). + + You will then clearly see the data get appended to the URL, separated with a + `?`-letter as GET forms are supposed to. + +# HTTP upload + +## PUT + + Perhaps the best way to upload data to an HTTP server is to use PUT. Then + again, this of course requires that someone put a program or script on the + server end that knows how to receive an HTTP PUT stream. + + Put a file to an HTTP server with curl: + + curl --upload-file uploadfile http://www.example.com/receive.cgi + +# HTTP Authentication + +## Basic Authentication + + HTTP Authentication is the ability to tell the server your username and + password so that it can verify that you are allowed to do the request you are + doing. The Basic authentication used in HTTP (which is the type curl uses by + default) is **plain text** based, which means it sends username and password + only slightly obfuscated, but still fully readable by anyone that sniffs on + the network between you and the remote server. + + To tell curl to use a user and password for authentication: + + curl --user name:password http://www.example.com + +## Other Authentication + + The site might require a different authentication method (check the headers + returned by the server), and then + [`--ntlm`](https://curl.se/docs/manpage.html#--ntlm), + [`--digest`](https://curl.se/docs/manpage.html#--digest), + [`--negotiate`](https://curl.se/docs/manpage.html#--negotiate) or even + [`--anyauth`](https://curl.se/docs/manpage.html#--anyauth) might be + options that suit you. + +## Proxy Authentication + + Sometimes your HTTP access is only available through the use of an HTTP + proxy. This seems to be especially common at various companies. An HTTP proxy + may require its own user and password to allow the client to get through to + the Internet. To specify those with curl, run something like: + + curl --proxy-user proxyuser:proxypassword curl.se + + If your proxy requires the authentication to be done using the NTLM method, + use [`--proxy-ntlm`](https://curl.se/docs/manpage.html#--proxy-ntlm), if + it requires Digest use + [`--proxy-digest`](https://curl.se/docs/manpage.html#--proxy-digest). + + If you use any one of these user+password options but leave out the password + part, curl will prompt for the password interactively. + +## Hiding credentials + + Do note that when a program is run, its parameters might be possible to see + when listing the running processes of the system. Thus, other users may be + able to watch your passwords if you pass them as plain command line + options. There are ways to circumvent this. + + It is worth noting that while this is how HTTP Authentication works, many + websites will not use this concept when they provide logins etc. See the Web + Login chapter further below for more details on that. + +# More HTTP Headers + +## Referer + + An HTTP request may include a 'referer' field (yes it is misspelled), which + can be used to tell from which URL the client got to this particular + resource. Some programs/scripts check the referer field of requests to verify + that this was not arriving from an external site or an unknown page. While + this is a stupid way to check something so easily forged, many scripts still + do it. Using curl, you can put anything you want in the referer-field and + thus more easily be able to fool the server into serving your request. + + Use curl to set the referer field with: + + curl --referer http://www.example.come http://www.example.com + +## User Agent + + Similar to the referer field, all HTTP requests may set the User-Agent + field. It names what user agent (client) that is being used. Many + applications use this information to decide how to display pages. Silly web + programmers try to make different pages for users of different browsers to + make them look the best possible for their particular browsers. They usually + also do different kinds of JavaScript etc. + + At times, you will see that getting a page with curl will not return the same + page that you see when getting the page with your browser. Then you know it + is time to set the User Agent field to fool the server into thinking you are + one of those browsers. + + To make curl look like Internet Explorer 5 on a Windows 2000 box: + + curl --user-agent "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" [URL] + + Or why not look like you are using Netscape 4.73 on an old Linux box: + + curl --user-agent "Mozilla/4.73 [en] (X11; U; Linux 2.2.15 i686)" [URL] + +## Redirects + +## Location header + + When a resource is requested from a server, the reply from the server may + include a hint about where the browser should go next to find this page, or a + new page keeping newly generated output. The header that tells the browser to + redirect is `Location:`. + + Curl does not follow `Location:` headers by default, but will simply display + such pages in the same manner it displays all HTTP replies. It does however + feature an option that will make it attempt to follow the `Location:` + pointers. + + To tell curl to follow a Location: + + curl --location http://www.example.com + + If you use curl to POST to a site that immediately redirects you to another + page, you can safely use + [`--location`](https://curl.se/docs/manpage.html#-L) (`-L`) and + `--data`/`--form` together. Curl will only use POST in the first request, and + then revert to GET in the following operations. + +## Other redirects + + Browsers typically support at least two other ways of redirects that curl + does not: first the html may contain a meta refresh tag that asks the browser + to load a specific URL after a set number of seconds, or it may use + JavaScript to do it. + +# Cookies + +## Cookie Basics + + The way the web browsers do "client side state control" is by using + cookies. Cookies are just names with associated contents. The cookies are + sent to the client by the server. The server tells the client for what path + and hostname it wants the cookie sent back, and it also sends an expiration + date and a few more properties. + + When a client communicates with a server with a name and path as previously + specified in a received cookie, the client sends back the cookies and their + contents to the server, unless of course they are expired. + + Many applications and servers use this method to connect a series of requests + into a single logical session. To be able to use curl in such occasions, we + must be able to record and send back cookies the way the web application + expects them. The same way browsers deal with them. + +## Cookie options + + The simplest way to send a few cookies to the server when getting a page with + curl is to add them on the command line like: + + curl --cookie "name=Daniel" http://www.example.com + + Cookies are sent as common HTTP headers. This is practical as it allows curl + to record cookies simply by recording headers. Record cookies with curl by + using the [`--dump-header`](https://curl.se/docs/manpage.html#-D) (`-D`) + option like: + + curl --dump-header headers_and_cookies http://www.example.com + + (Take note that the + [`--cookie-jar`](https://curl.se/docs/manpage.html#-c) option described + below is a better way to store cookies.) + + Curl has a full blown cookie parsing engine built-in that comes in use if you + want to reconnect to a server and use cookies that were stored from a + previous connection (or hand-crafted manually to fool the server into + believing you had a previous connection). To use previously stored cookies, + you run curl like: + + curl --cookie stored_cookies_in_file http://www.example.com + + Curl's "cookie engine" gets enabled when you use the + [`--cookie`](https://curl.se/docs/manpage.html#-b) option. If you only + want curl to understand received cookies, use `--cookie` with a file that + does not exist. Example, if you want to let curl understand cookies from a + page and follow a location (and thus possibly send back cookies it received), + you can invoke it like: + + curl --cookie nada --location http://www.example.com + + Curl has the ability to read and write cookie files that use the same file + format that Netscape and Mozilla once used. It is a convenient way to share + cookies between scripts or invokes. The `--cookie` (`-b`) switch + automatically detects if a given file is such a cookie file and parses it, + and by using the `--cookie-jar` (`-c`) option you will make curl write a new + cookie file at the end of an operation: + + curl --cookie cookies.txt --cookie-jar newcookies.txt \ + http://www.example.com + +# HTTPS + +## HTTPS is HTTP secure + + There are a few ways to do secure HTTP transfers. By far the most common + protocol for doing this is what is generally known as HTTPS, HTTP over + SSL. SSL encrypts all the data that is sent and received over the network and + thus makes it harder for attackers to spy on sensitive information. + + SSL (or TLS as the current version of the standard is called) offers a set of + advanced features to do secure transfers over HTTP. + + Curl supports encrypted fetches when built to use a TLS library and it can be + built to use one out of a fairly large set of libraries - `curl -V` will show + which one your curl was built to use (if any!). To get a page from an HTTPS + server, simply run curl like: + + curl https://secure.example.com + +## Certificates + + In the HTTPS world, you use certificates to validate that you are the one + you claim to be, as an addition to normal passwords. Curl supports client- + side certificates. All certificates are locked with a pass phrase, which you + need to enter before the certificate can be used by curl. The pass phrase + can be specified on the command line or if not, entered interactively when + curl queries for it. Use a certificate with curl on an HTTPS server like: + + curl --cert mycert.pem https://secure.example.com + + curl also tries to verify that the server is who it claims to be, by + verifying the server's certificate against a locally stored CA cert + bundle. Failing the verification will cause curl to deny the connection. You + must then use [`--insecure`](https://curl.se/docs/manpage.html#-k) + (`-k`) in case you want to tell curl to ignore that the server cannot be + verified. + + More about server certificate verification and ca cert bundles can be read in + the [`SSLCERTS` document](https://curl.se/docs/sslcerts.html). + + At times you may end up with your own CA cert store and then you can tell + curl to use that to verify the server's certificate: + + curl --cacert ca-bundle.pem https://example.com/ + +# Custom Request Elements + +## Modify method and headers + + Doing fancy stuff, you may need to add or change elements of a single curl + request. + + For example, you can change the POST method to `PROPFIND` and send the data + as `Content-Type: text/xml` (instead of the default `Content-Type`) like + this: + + curl --data "" --header "Content-Type: text/xml" \ + --request PROPFIND example.com + + You can delete a default header by providing one without content. Like you + can ruin the request by chopping off the `Host:` header: + + curl --header "Host:" http://www.example.com + + You can add headers the same way. Your server may want a `Destination:` + header, and you can add it: + + curl --header "Destination: http://nowhere" http://example.com + +## More on changed methods + + It should be noted that curl selects which methods to use on its own + depending on what action to ask for. `-d` will do POST, `-I` will do HEAD and + so on. If you use the [`--request`](https://curl.se/docs/manpage.html#-X) / + `-X` option you can change the method keyword curl selects, but you will not + modify curl's behavior. This means that if you for example use -d "data" to + do a POST, you can modify the method to a `PROPFIND` with `-X` and curl will + still think it sends a POST. You can change the normal GET to a POST method + by simply adding `-X POST` in a command line like: + + curl -X POST http://example.org/ + + curl will however still act as if it sent a GET so it will not send any + request body etc. + +# Web Login + +## Some login tricks + + While not strictly just HTTP related, it still causes a lot of people + problems so here's the executive run-down of how the vast majority of all + login forms work and how to login to them using curl. + + It can also be noted that to do this properly in an automated fashion, you + will most certainly need to script things and do multiple curl invokes etc. + + First, servers mostly use cookies to track the logged-in status of the + client, so you will need to capture the cookies you receive in the + responses. Then, many sites also set a special cookie on the login page (to + make sure you got there through their login page) so you should make a habit + of first getting the login-form page to capture the cookies set there. + + Some web-based login systems feature various amounts of JavaScript, and + sometimes they use such code to set or modify cookie contents. Possibly they + do that to prevent programmed logins, like this manual describes how to... + Anyway, if reading the code is not enough to let you repeat the behavior + manually, capturing the HTTP requests done by your browsers and analyzing the + sent cookies is usually a working method to work out how to shortcut the + JavaScript need. + + In the actual `
` tag for the login, lots of sites fill-in + random/session or otherwise secretly generated hidden tags and you may need + to first capture the HTML code for the login form and extract all the hidden + fields to be able to do a proper login POST. Remember that the contents need + to be URL encoded when sent in a normal POST. + +# Debug + +## Some debug tricks + + Many times when you run curl on a site, you will notice that the site does not + seem to respond the same way to your curl requests as it does to your + browser's. + + Then you need to start making your curl requests more similar to your + browser's requests: + + - Use the `--trace-ascii` option to store fully detailed logs of the requests + for easier analyzing and better understanding + + - Make sure you check for and use cookies when needed (both reading with + `--cookie` and writing with `--cookie-jar`) + + - Set user-agent (with [`-A`](https://curl.se/docs/manpage.html#-A)) to + one like a recent popular browser does + + - Set referer (with [`-E`](https://curl.se/docs/manpage.html#-E)) like + it is set by the browser + + - If you use POST, make sure you send all the fields and in the same order as + the browser does it. + +## Check what the browsers do + + A good helper to make sure you do this right, is the web browsers' developers + tools that let you view all headers you send and receive (even when using + HTTPS). + + A more raw approach is to capture the HTTP traffic on the network with tools + such as Wireshark or tcpdump and check what headers that were sent and + received by the browser. (HTTPS forces you to use `SSLKEYLOGFILE` to do + that.) diff --git a/src/ext/curl/docs/URL-SYNTAX.md b/src/ext/curl/docs/URL-SYNTAX.md new file mode 100644 index 00000000..011a32c3 --- /dev/null +++ b/src/ext/curl/docs/URL-SYNTAX.md @@ -0,0 +1,391 @@ +# URL syntax and their use in curl + +## Specifications + +The official "URL syntax" is primarily defined in these two different +specifications: + + - [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986) (although URL is called + "URI" in there) + - [The WHATWG URL Specification](https://url.spec.whatwg.org/) + +RFC 3986 is the earlier one, and curl has always tried to adhere to that one +(since it shipped in January 2005). + +The WHATWG URL spec was written later, is incompatible with the RFC 3986 and +changes over time. + +## Variations + +URL parsers as implemented in browsers, libraries and tools usually opt to +support one of the mentioned specifications. Bugs, differences in +interpretations and the moving nature of the WHATWG spec does however make it +unlikely that multiple parsers treat URLs the same way. + +## Security + +Due to the inherent differences between URL parser implementations, it is +considered a security risk to mix different implementations and assume the +same behavior! + +For example, if you use one parser to check if a URL uses a good hostname or +the correct auth field, and then pass on that same URL to a *second* parser, +there will always be a risk it treats the same URL differently. There is no +right and wrong in URL land, only differences of opinions. + +libcurl offers a separate API to its URL parser for this reason, among others. + +Applications may at times find it convenient to allow users to specify URLs +for various purposes and that string would then end up fed to curl. Getting a +URL from an external untrusted party and using it with curl brings several +security concerns: + +1. If you have an application that runs as or in a server application, getting + an unfiltered URL can trick your application to access a local resource + instead of a remote resource. Protecting yourself against localhost accesses + is hard when accepting user provided URLs. + +2. Such custom URLs can access other ports than you planned as port numbers + are part of the regular URL format. The combination of a local host and a + custom port number can allow external users to play tricks with your local + services. + +3. Such a URL might use other schemes than you thought of or planned for. + +## "RFC 3986 plus" + +curl recognizes a URL syntax that we call "RFC 3986 plus". It is grounded on +the well established RFC 3986 to make sure previously written command lines and +curl using scripts will remain working. + +curl's URL parser allows a few deviations from the spec in order to +inter-operate better with URLs that appear in the wild. + +### spaces + +A URL provided to curl cannot contain spaces. They need to be provided URL +encoded to be accepted in a URL by curl. + +An exception to this rule: `Location:` response headers that indicate to a +client where a resource has been redirected to, sometimes contain spaces. This +is a violation of RFC 3986 but is fine in the WHATWG spec. curl handles these +by re-encoding them to `%20`. + +### non-ASCII + +Byte values in a provided URL that are outside of the printable ASCII range +are percent-encoded by curl. + +### multiple slashes + +An absolute URL always starts with a "scheme" followed by a colon. For all the +schemes curl supports, the colon must be followed by two slashes according to +RFC 3986 but not according to the WHATWG spec - which allows one to infinity +amount. + +curl allows one, two or three slashes after the colon to still be considered a +valid URL. + +### "scheme-less" + +curl supports "URLs" that do not start with a scheme. This is not supported by +any of the specifications. This is a shortcut to entering URLs that was +supported by browsers early on and has been mimicked by curl. + +Based on what the hostname starts with, curl will "guess" what protocol to +use: + + - `ftp.` means FTP + - `dict.` means DICT + - `ldap.` means LDAP + - `imap.` means IMAP + - `smtp.` means SMTP + - `pop3.` means POP3 + - all other means HTTP + +### globbing letters + +The curl command line tool supports "globbing" of URLs. It means that you can +create ranges and lists using `[N-M]` and `{one,two,three}` sequences. The +letters used for this (`[]{}`) are reserved in RFC 3986 and can therefore not +legitimately be part of such a URL. + +They are however not reserved or special in the WHATWG specification, so +globbing can mess up such URLs. Globbing can be turned off for such occasions +(using `--globoff`). + +# URL syntax details + +A URL may consist of the following components - many of them are optional: + + [scheme][divider][userinfo][hostname][port number][path][query][fragment] + +Each component is separated from the following component with a divider +character or string. + +For example, this could look like: + + http://user:password@www.example.com:80/index.html?foo=bar#top + +## Scheme + +The scheme specifies the protocol to use. A curl build can support a few or +many different schemes. You can limit what schemes curl should accept. + +curl supports the following schemes on URLs specified to transfer. They are +matched case insensitively: + +`dict`, `file`, `ftp`, `ftps`, `gopher`, `gophers`, `http`, `https`, `imap`, +`imaps`, `ldap`, `ldaps`, `mqtt`, `pop3`, `pop3s`, `rtmp`, `rtmpe`, `rtmps`, +`rtmpt`, `rtmpte`, `rtmpts`, `rtsp`, `smb`, `smbs`, `smtp`, `smtps`, `telnet`, +`tftp` + +When the URL is specified to identify a proxy, curl recognizes the following +schemes: + +`http`, `https`, `socks4`, `socks4a`, `socks5`, `socks5h`, `socks` + +## Userinfo + +The userinfo field can be used to set user name and password for +authentication purposes in this transfer. The use of this field is discouraged +since it often means passing around the password in plain text and is thus a +security risk. + +URLs for IMAP, POP3 and SMTP also support *login options* as part of the +userinfo field. They are provided as a semicolon after the password and then +the options. + +## Hostname + +The hostname part of the URL contains the address of the server that you want +to connect to. This can be the fully qualified domain name of the server, the +local network name of the machine on your network or the IP address of the +server or machine represented by either an IPv4 or IPv6 address (within +brackets). For example: + + http://www.example.com/ + + http://hostname/ + + http://192.168.0.1/ + + http://[2001:1890:1112:1::20]/ + +### "localhost" + +Starting in curl 7.77.0, curl uses loopback IP addresses for the name +`localhost`: `127.0.0.1` and `::1`. It does not resolve the name using the +resolver functions. + +This is done to make sure the host accessed is truly the localhost - the local +machine. + +### IDNA + +If curl was built with International Domain Name (IDN) support, it can also +handle host names using non-ASCII characters. + +When built with libidn2, curl uses the IDNA 2008 standard. This is equivalent +to the WHATWG URL spec, but differs from certain browsers that use IDNA 2003 +Transitional Processing. The two standards have a huge overlap but differ +slightly, perhaps most famously in how they deal with the German "double s" +(`ß`). + +When winidn is used, curl uses IDNA 2003 Transitional Processing, like the rest +of Windows. + +## Port number + +If there is a colon after the hostname, that should be followed by the port +number to use. 1 - 65535. curl also supports a blank port number field - but +only if the URL starts with a scheme. + +If the port number is not specified in the URL, curl will used a default port +based on the provide scheme: + +DICT 2628, FTP 21, FTPS 990, GOPHER 70, GOPHERS 70, HTTP 80, HTTPS 443, +IMAP 132, IMAPS 993, LDAP 369, LDAPS 636, MQTT 1883, POP3 110, POP3S 995, +RTMP 1935, RTMPS 443, RTMPT 80, RTSP 554, SCP 22, SFTP 22, SMB 445, SMBS 445, +SMTP 25, SMTPS 465, TELNET 23, TFTP 69 + +# Scheme specific behaviors + +## FTP + +The path part of an FTP request specifies the file to retrieve and from which +directory. If the file part is omitted then libcurl downloads the directory +listing for the directory specified. If the directory is omitted then the +directory listing for the root / home directory will be returned. + +FTP servers typically put the user in its "home directory" after login, which +then differs between users. To explicitly specify the root directory of an FTP +server, start the path with double slash `//` or `/%2f` (2F is the hexadecimal +value of the ascii code for the slash). + +## FILE + +When a `FILE://` URL is accessed on Windows systems, it can be crafted in a +way so that Windows attempts to connect to a (remote) machine when curl wants +to read or write such a path. + +curl only allows the hostname part of a FILE URL to be one out of these three +alternatives: `localhost`, `127.0.0.1` or blank ("", zero characters). +Anything else will make curl fail to parse the URL. + +### Windows-specific FILE details + +curl accepts that the FILE URL's path starts with a "drive letter". That is a +single letter `a` to `z` followed by a colon or a pipe character (`|`). + +The Windows operating system itself will convert some file accesses to perform +network accesses over SMB/CIFS, through several different file path patterns. +This way, a `file://` URL passed to curl *might* be converted into a network +access inadvertently and unknowingly to curl. This is a Windows feature curl +cannot control or disable. + +## IMAP + +The path part of an IMAP request not only specifies the mailbox to list or +select, but can also be used to check the `UIDVALIDITY` of the mailbox, to +specify the `UID`, `SECTION` and `PARTIAL` octets of the message to fetch and +to specify what messages to search for. + +A top level folder list: + + imap://user:password@mail.example.com + +A folder list on the user's inbox: + + imap://user:password@mail.example.com/INBOX + +Select the user's inbox and fetch message with `uid = 1`: + + imap://user:password@mail.example.com/INBOX/;UID=1 + +Select the user's inbox and fetch the first message in the mail box: + + imap://user:password@mail.example.com/INBOX/;MAILINDEX=1 + +Select the user's inbox, check the `UIDVALIDITY` of the mailbox is 50 and +fetch message 2 if it is: + + imap://user:password@mail.example.com/INBOX;UIDVALIDITY=50/;UID=2 + +Select the user's inbox and fetch the text portion of message 3: + + imap://user:password@mail.example.com/INBOX/;UID=3/;SECTION=TEXT + +Select the user's inbox and fetch the first 1024 octets of message 4: + + imap://user:password@mail.example.com/INBOX/;UID=4/;PARTIAL=0.1024 + +Select the user's inbox and check for NEW messages: + + imap://user:password@mail.example.com/INBOX?NEW + +Select the user's inbox and search for messages containing "shadows" in the +subject line: + + imap://user:password@mail.example.com/INBOX?SUBJECT%20shadows + +Searching via the query part of the URL `?` is a search request for the +results to be returned as message sequence numbers (`MAILINDEX`). It is +possible to make a search request for results to be returned as unique ID +numbers (`UID`) by using a custom curl request via `-X`. `UID` numbers are +unique per session (and multiple sessions when `UIDVALIDITY` is the same). For +example, if you are searching for `"foo bar"` in header+body (`TEXT`) and you +want the matching `MAILINDEX` numbers returned then you could search via URL: + + imap://user:password@mail.example.com/INBOX?TEXT%20%22foo%20bar%22 + +If you want matching `UID` numbers you have to use a custom request: + + imap://user:password@mail.example.com/INBOX -X "UID SEARCH TEXT \"foo bar\"" + +For more information about IMAP commands please see RFC 9051. For more +information about the individual components of an IMAP URL please see RFC 5092. + +* Note old curl versions would `FETCH` by message sequence number when `UID` +was specified in the URL. That was a bug fixed in 7.62.0, which added +`MAILINDEX` to `FETCH` by mail sequence number. + +## LDAP + +The path part of a LDAP request can be used to specify the: Distinguished +Name, Attributes, Scope, Filter and Extension for a LDAP search. Each field is +separated by a question mark and when that field is not required an empty +string with the question mark separator should be included. + +Search for the `DN` as `My Organization`: + + ldap://ldap.example.com/o=My%20Organization + +the same search but will only return `postalAddress` attributes: + + ldap://ldap.example.com/o=My%20Organization?postalAddress + +Search for an empty `DN` and request information about the +`rootDomainNamingContext` attribute for an Active Directory server: + + ldap://ldap.example.com/?rootDomainNamingContext + +For more information about the individual components of a LDAP URL please +see [RFC 4516](https://datatracker.ietf.org/doc/html/rfc4516). + +## POP3 + +The path part of a POP3 request specifies the message ID to retrieve. If the +ID is not specified then a list of waiting messages is returned instead. + +## SCP + +The path part of an SCP URL specifies the path and file to retrieve or +upload. The file is taken as an absolute path from the root directory on the +server. + +To specify a path relative to the user's home directory on the server, prepend +`~/` to the path portion. + +## SFTP + +The path part of an SFTP URL specifies the file to retrieve or upload. If the +path ends with a slash (`/`) then a directory listing is returned instead of a +file. If the path is omitted entirely then the directory listing for the root +/ home directory will be returned. + +## SMB +The path part of a SMB request specifies the file to retrieve and from what +share and directory or the share to upload to and as such, may not be omitted. +If the user name is embedded in the URL then it must contain the domain name +and as such, the backslash must be URL encoded as %2f. + +When uploading to SMB, the size of the file needs to be known ahead of time, +meaning that you can upload a file passed to curl over a pipe like stdin. + +curl supports SMB version 1 (only) + +## SMTP + +The path part of a SMTP request specifies the hostname to present during +communication with the mail server. If the path is omitted, then libcurl will +attempt to resolve the local computer's hostname. However, this may not +return the fully qualified domain name that is required by some mail servers +and specifying this path allows you to set an alternative name, such as your +machine's fully qualified domain name, which you might have obtained from an +external function such as gethostname or getaddrinfo. + +The default smtp port is 25. Some servers use port 587 as an alternative. + +## RTMP + +There is no official URL spec for RTMP so libcurl uses the URL syntax supported +by the underlying librtmp library. It has a syntax where it wants a +traditional URL, followed by a space and a series of space-separated +`name=value` pairs. + +While space is not typically a "legal" letter, libcurl accepts them.

The numbers to the + right of a bumped number will be reset to zero. + + The main version number will get bumped when *really* big, world colliding + changes are made. The release number is bumped when changes are performed or + things/features are added. The patch number is bumped when the changes are + mere bugfixes. + + It means that after release 1.2.3, we can release 2.0.0 if something really + big has been made, 1.3.0 if not that big changes were made or 1.2.4 if only + bugs were fixed. + + Bumping, as in increasing the number with 1, is unconditionally only + affecting one of the numbers (except the ones to the right of it, that may be + set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99 + becomes 100.

That means, for example, that a +bug tracker entry must NOT be created to track the issue since that will make +the issue public and it should not be discussed on any of the project's public +mailing lists. Messages associated with any commits should not make any +reference to the security nature of the commit if done prior to the public +announcement. + +- The person discovering the issue, the reporter, reports the vulnerability on + [HackerOne](https://hackerone.com/curl). Issues filed there reach a handful + of selected and trusted people. + +- Messages that do not relate to the reporting or managing of an undisclosed + security vulnerability in curl or libcurl are ignored and no further action + is required. + +- A person in the security team responds to the original report to acknowledge + that a human has seen the report. + +- The security team investigates the report and either rejects it or accepts + it. See below for examples of problems that are not considered + vulnerabilities. + +- If the report is rejected, the team writes to the reporter to explain why. + +- If the report is accepted, the team writes to the reporter to let them + know it is accepted and that they are working on a fix. + +- The security team discusses the problem, works out a fix, considers the + impact of the problem and suggests a release schedule. This discussion + should involve the reporter as much as possible. + +- The release of the information should be "as soon as possible" and is most + often synchronized with an upcoming release that contains the fix. If the + reporter, or anyone else involved, thinks the next planned release is too + far away, then a separate earlier release should be considered. + +- Write a security advisory draft about the problem that explains what the + problem is, its impact, which versions it affects, solutions or workarounds, + when the release is out and make sure to credit all contributors properly. + Figure out the CWE (Common Weakness Enumeration) number for the flaw.

It gets sent to the + curl-announce, curl-library and curl-users mailing lists. + +- The security webpage on the website should get the new vulnerability + mentioned. + +## security (at curl dot se) + +This is a private mailing list for discussions on and about curl security +issues. + +Who is on this list? There are a couple of criteria you must meet, and then we +might ask you to join the list or you can ask to join it. It really is not a +formal process. We basically only require that you have a long-term presence +in the curl project and you have shown an understanding for the project and +its way of working. You must have been around for a good while and you should +have no plans of vanishing in the near future. + +We do not make the list of participants public mostly because it tends to vary +somewhat over time and a list somewhere will only risk getting outdated. + +## Publishing Security Advisories + +1. Write up the security advisory, using markdown syntax. Use the same + subtitles as last time to maintain consistency. + +2. Name the advisory file after the allocated CVE id. + +3. Add a line on the top of the array in `curl-www/docs/vuln.pm`. + +4. Put the new advisory markdown file in the `curl-www/docs/` directory. Add it + to the git repository. + +5. Run `make` in your local web checkout and verify that things look fine. + +6. On security advisory release day, push the changes on the curl-www + repository's remote master branch. + +## HackerOne + +Request the issue to be disclosed. If there are sensitive details present in +the report and discussion, those should be redacted from the disclosure. The +default policy is to disclose as much as possible as soon as the vulnerability +has been published. + +## Bug Bounty + +See [BUG-BOUNTY](https://curl.se/docs/bugbounty.html) for details on the +bug bounty program. + +# Severity levels + +The curl project's security team rates security problems using four severity +levels depending how serious we consider the problem to be. We use **Low**, +**Medium**, **High** and **Critical**. We refrain from using numerical scoring +of vulnerabilities. + +When deciding severity level on a particular issue, we take all the factors +into account: attack vector, attack complexity, required privileges, necessary +build configuration, protocols involved, platform specifics and also what +effects a possible exploit or trigger of the issue can lead do, including +confidentiality, integrity or availability problems. + +## Low + +This is a security problem that is truly hard or unlikely to exploit or +trigger. Due to timing, platform requirements or the fact that options or +protocols involved are rare etc. [Past +example](https://curl.se/docs/CVE-2022-43552.html) + +## Medium + +This is a security problem that is less hard than **Low** to exploit or +trigger. Less strict timing, wider platforms availability or involving more +widely used options or protocols. A problem that usually needs something else +to also happen to become serious. [Past +example](https://curl.se/docs/CVE-2022-32206.html) + +## High + +This issue in itself a serious problem with real world impact. Flaws that can +easily compromise the confidentiality, integrity or availability of resources. +Exploiting or triggering this problem is not hard. [Past +example](https://curl.se/docs/CVE-2019-3822.html) + +## Critical + +Easily exploitable by a remote unauthenticated attacker and lead to system +compromise (arbitrary code execution) without requiring user interaction, with +a common configuration on a popular platform. This issue has few restrictions +and requirements and can be exploited easily using most curl configurations. +[Past example](https://curl.se/docs/CVE-2000-0973.html) + +# Not security issues + +This is an incomplete list of issues that are not considered vulnerabilities. + +## Small memory leaks + +We do not consider a small memory leak a security problem; even if the amount +of allocated memory grows by a small amount every now and then. Long-living +applications and services already need to have counter-measures and deal with +growing memory usage, be it leaks or just increased use. A small memory or +resource leak is then expected to *not* cause a security problem. + +Of course there can be a discussion if a leak is small or not. A large leak +can be considered a security problem due to the DOS risk. If leaked memory +contains sensitive data it might also qualify as a security problem. + +## Never-ending transfers + +We do not consider flaws that cause a transfer to never end to be a security +problem. There are already several benign and likely reasons for transfers to +stall and never end, so applications that cannot deal with never-ending +transfers already need to have counter-measures established. + +If the problem avoids the regular counter-measures when it causes a never- +ending transfer, it might be a security problem. + +## Not practically possible + +If the flaw or vulnerability cannot practically get executed on existing +hardware it is not a security problem. + +## API misuse + +If a reported issue only triggers by an application using the API in a way +that is not documented to work or even documented to not work, it is probably +not going to be considered a security problem. We only guarantee secure and +proper functionality when the APIs are used as expected and documented. + +There can be a discussion about what the documentation actually means and how +to interpret the text, which might end up with us still agreeing that it is a +security problem. + +## Local attackers already present + +When an issue can only be attacked or misused by an attacker present on the +local system or network, the bar is raised. If a local user wrongfully has +elevated rights on your system enough to attack curl, they can probably +already do much worse harm and the problem is not really in curl. + +## Experiments + +Vulnerabilities in features which are off by default (in the build) and +documented as experimental, are not eligible for a reward and we do not +consider them security problems. + +## URL inconsistencies + +URL parser inconsistencies between browsers and curl are expected and are not +considered security vulnerabilities. The WHATWG URL Specification and RFC +3986+ (the plus meaning that it is an extended version) [are not completely +interoperable](https://github.com/bagder/docs/blob/master/URL-interop.md). + +Obvious parser bugs can still be vulnerabilities of course. + +## Visible command line arguments + +The curl command blanks the contents of a number of command line arguments to +prevent them from appearing in process listings. It does not blank all +arguments even if some of them that are not blanked might contain sensitive +data. We consider this functionality a best-effort and omissions are not +security vulnerabilities. + + - not all systems allow the arguments to be blanked in the first place + - since curl blanks the argument itself they will be readable for a short + moment no matter what + - virtually every argument can contain sensitive data, depending on use + - blanking all arguments would make it impractical for users to differentiate + curl command lines in process listings + +## Busy-loops + +Busy-loops that consume 100% CPU time but eventually end (perhaps due to a set +timeout value or otherwise) are not considered security problems. Applications +are supposed to already handle situations when the transfer loop legitimately +consumes 100% CPU time, so while a prolonged such busy-loop is a nasty bug, we +do not consider it a security problem. + +## Saving files + +curl cannot protect against attacks where an attacker has write access to the +same directory where curl is directed to save files. + +## Tricking a user to run a command line + +A creative, misleading or funny looking command line is not a security +problem. The curl command line tool takes options and URLs on the command line +and if an attacker can trick the user to run a specifically crafted curl +command line, all bets are off. Such an attacker can just as well have the +user run a much worse command that can do something fatal (like +`sudo rm -rf /`). + +## Terminal output and escape sequences + +Content that is transferred from a server and gets displayed in a terminal by +curl may contain escape sequences or use other tricks to fool the user. This +is curl working as designed and is not a curl security problem. Escape +sequences, moving cursor, changing color etc, is also frequently used for +good. To reduce the risk of getting fooled, save files and browse them after +download using a display method that minimizes risks. diff --git a/src/ext/curl/docs/WEBSOCKET.md b/src/ext/curl/docs/WEBSOCKET.md new file mode 100644 index 00000000..c3967b8e --- /dev/null +++ b/src/ext/curl/docs/WEBSOCKET.md @@ -0,0 +1,135 @@ + + +# WebSocket in curl + +## URL + +WebSocket communication with libcurl is done by setting up a transfer to a URL +using the `ws://` or `wss://` URL schemes.

The +lower case version has precedence. `http_proxy` is an exception as it is only +available in lower case. + +Using an environment variable to set the proxy has the same effect as using +the --proxy option. + +## `http_proxy` [protocol://][:port] +Sets the proxy server to use for HTTP. + +## `HTTPS_PROXY` [protocol://][:port] +Sets the proxy server to use for HTTPS. + +## `[url-protocol]_PROXY` [protocol://][:port] +Sets the proxy server to use for [url-protocol], where the protocol is a +protocol that curl supports and as specified in a URL. FTP, FTPS, POP3, IMAP, +SMTP, LDAP, etc. + +## `ALL_PROXY` [protocol://][:port] +Sets the proxy server to use if no protocol-specific proxy is set. + +## `NO_PROXY` +list of host names that should not go through any proxy. If set to an asterisk +'*' only, it matches all hosts. Each name in this list is matched as either +a domain name which contains the hostname, or the hostname itself. + +This environment variable disables use of the proxy even when specified with +the --proxy option. That is + + NO_PROXY=direct.example.com curl -x http://proxy.example.com + http://direct.example.com + +accesses the target URL directly, and + + NO_PROXY=direct.example.com curl -x http://proxy.example.com + http://somewhere.example.com + +accesses the target URL through the proxy. + +The list of host names can also be include numerical IP addresses, and IPv6 +versions should then be given without enclosing brackets. + +IP addresses can be specified using CIDR notation: an appended slash and +number specifies the number of "network bits" out of the address to use in the +comparison (added in 7.86.0). For example "192.168.0.0/16" would match all +addresses starting with "192.168". + +## `APPDATA` +On Windows, this variable is used when trying to find the home directory. If +the primary home variable are all unset. + +## `COLUMNS` +If set, the specified number of characters is used as the terminal width when +the alternative progress-bar is shown. If not set, curl tries to figure it out +using other ways. + +## `CURL_CA_BUNDLE` +If set, it is used as the --cacert value. This environment variable is ignored +if Schannel is used as the TLS backend. + +## `CURL_HOME` +If set, is the first variable curl checks when trying to find its home +directory. If not set, it continues to check *XDG_CONFIG_HOME* + +## `CURL_SSL_BACKEND` +If curl was built with support for "MultiSSL", meaning that it has built-in +support for more than one TLS backend, this environment variable can be set to +the case insensitive name of the particular backend to use when curl is +invoked. Setting a name that is not a built-in alternative makes curl stay +with the default. + +SSL backend names (case-insensitive): **bearssl**, **gnutls**, **mbedtls**, +**openssl**, **rustls**, **schannel**, **secure-transport**, **wolfssl** + +## `HOME` +If set, this is used to find the home directory when that is needed. Like when +looking for the default .curlrc. *CURL_HOME* and *XDG_CONFIG_HOME* +have preference. + +## `QLOGDIR` +If curl was built with HTTP/3 support, setting this environment variable to a +local directory makes curl produce **qlogs** in that directory, using file +names named after the destination connection id (in hex). Do note that these +files can become rather large.

This environment variable is ignored +if Schannel is used as the TLS backend. + +## `SSL_CERT_FILE` +If set, it is used as the --cacert value. This environment variable is ignored +if Schannel is used as the TLS backend. + +## `SSLKEYLOGFILE` +If you set this environment variable to a file name, curl stores TLS secrets +from its connections in that file when invoked to enable you to analyze the +TLS traffic in real time using network analyzing tools such as Wireshark. This +works with the following TLS backends: OpenSSL, libressl, BoringSSL, GnuTLS +and wolfSSL. + +## `USERPROFILE` +On Windows, this variable is used when trying to find the home directory. If +the other, primary, variable are all unset.

Similarly, +you must escape the double quote character as \" so that it is not recognized +as an escape character. + +If curl is built against OpenSSL library, and the engine pkcs11 is available, +then a PKCS#11 URI (RFC 7512) can be used to specify a certificate located in +a PKCS#11 device.

If a PKCS#11 URI is provided, then the --engine option is set as +"pkcs11" if none was provided and the --cert-type option is set as "ENG" if +none was provided. + +(iOS and macOS only) If curl is built against Secure Transport, then the +certificate string can either be the name of a certificate/private key in the +system or user keychain, or the path to a PKCS#12-encoded certificate and +private key. If you want to use a file from the current directory, please +precede it with "./" prefix, in order to avoid confusion with a nickname. + +(Schannel only) Client certificates must be specified by a path expression to +a certificate store. (Loading *PFX* is not supported; you can import it to a +store first).

Your application can remain using libcurl just as before, only with + fewer bugs and possibly with added new features. + +## Version Numbers + + In libcurl land, you cannot tell by the libcurl version number if that + libcurl is binary compatible or not with another libcurl version.

Then the library + will get a different output name and thus can in fact be installed in + parallel with an older installed lib (on most systems). Thus, old + applications built against the previous ABI version will remain working and + using the older lib, while newer applications build and use the newer one. + + During the first seven years of libcurl releases, there have only been four + ABI breakages. + + We are determined to bump the SONAME as rarely as possible.

If the returned +header struct has **amount** set larger than 1, it means there are more +instances of the same header name available to get. Asking for a too big index +makes **CURLHE_BADINDEX** get returned. + +The *origin* argument is for specifying which headers to receive, as a single +HTTP transfer might provide headers from several different places and they may +then have different importance to the user and headers using the same name +might be used. The *origin* is a bitmask for what header sources you want. See +the descriptions below. + +The *request* argument tells libcurl from which request you want headers +from. A single transfer might consist of a series of HTTP requests and this +argument lets you specify which particular individual request you want the +headers from. 0 being the first request and then the number increases for +further redirects or when multi-state authentication is used. Passing in -1 is +a shortcut to "the last" request in the series, independently of the actual +amount of requests used. + +libcurl stores and provides the actually used "correct" headers. If for +example two headers with the same name arrive and the latter overrides the +former, then only the latter is provided. If the first header survives the +second, then only the first one is provided. An application using this API +does not have to bother about multiple headers used wrongly. + +The memory for the returned struct is associated with the easy handle and +subsequent calls to curl_easy_header(3) clobber the struct used in the +previous calls for the same easy handle. Applications need to copy the data if +it wants to keep it around. The memory used for the struct gets freed with +calling curl_easy_cleanup(3) of the easy handle. + +The first line in an HTTP response is called the status line. It is not +considered a header by this function. Headers are the "name: value" lines +following the status. + +This function can be used before (all) headers have been received and is fine +to call from within libcurl callbacks. It returns the state of the headers at +the time it is called. + +# The header struct + +~~~c +struct curl_header { + char *name; + char *value; + size_t amount; + size_t index; + unsigned int origin; + void *anchor; +}; +~~~ + +The data **name** field points to, is the same as the requested name, but +might have a different case. + +The data **value** field points to, comes exactly as delivered over the +network but with leading and trailing whitespace and newlines stripped +off. The `value` data is null-terminated. For legacy HTTP/1 "folded headers", +this API provides the full single value in an unfolded manner with a single +whitespace between the lines. + +**amount** is how many headers using this name that exist, within the origin +and request scope asked for. + +**index** is the zero based entry number of this particular header, which in +case this header was used more than once in the requested scope can be larger +than 0 but is always less than **amount**. + +The **origin** field in the "curl_header" struct has one of the origin bits +set, indicating where from the header originates.

Unlike +most other libcurl functions, curl_easy_pause(3) can be used from within +callbacks. + +A connection can be paused by using this function or by letting the read or +the write callbacks return the proper magic return code +(*CURL_READFUNC_PAUSE* and *CURL_WRITEFUNC_PAUSE*). A write callback +that returns pause signals to the library that it could not take care of any +data at all, and that data is then delivered again to the callback when the +transfer is unpaused. + +While it may feel tempting, take care and notice that you cannot call this +function from another thread. To unpause, you may for example call it from the +progress callback (CURLOPT_PROGRESSFUNCTION(3)). + +When this function is called to unpause receiving, the write callback might +get called before this function returns to deliver cached content. When +libcurl delivers such cached data to the write callback, it is delivered as +fast as possible, which may overstep the boundary set in +CURLOPT_MAX_RECV_SPEED_LARGE(3) etc. + +The **handle** argument identifies the transfer you want to pause or +unpause. + +A paused transfer is excluded from low speed cancels via the +CURLOPT_LOW_SPEED_LIMIT(3) option and unpausing a transfer resets the +time period required for the low speed limit to be met. + +The **bitmask** argument is a set of bits that sets the new state of the +connection. The following bits can be used: + +## CURLPAUSE_RECV + +Pause receiving data. There is no data received on this connection until this +function is called again without this bit set. Thus, the write callback +(CURLOPT_WRITEFUNCTION(3)) is not called. + +## CURLPAUSE_SEND + +Pause sending data.

Thus, the read callback +(CURLOPT_READFUNCTION(3)) is not called. + +## CURLPAUSE_ALL + +Convenience define that pauses both directions. + +## CURLPAUSE_CONT + +Convenience define that unpauses both directions. + +# LIMITATIONS + +The pausing of transfers does not work with protocols that work without +network connectivity, like FILE://. Trying to pause such a transfer, in any +direction, might cause problems or error. + +# MULTIPLEXED + +When a connection is used multiplexed, like for HTTP/2, and one of the +transfers over the connection is paused and the others continue flowing, +libcurl might end up buffering contents for the paused transfer. It has to do +this because it needs to drain the socket for the other transfers and the +already announced window size for the paused transfer allows the server to +continue sending data up to that window size amount. By default, libcurl +announces a 32 megabyte window size, which thus can make libcurl end up +buffering 32 megabyte of data for a paused stream. + +When such a paused stream is unpaused again, any buffered data is delivered +first. + +# EXAMPLE + +~~~c +int main(void) +{ + CURL *curl = curl_easy_init(); + if(curl) { + /* pause a transfer in both directions */ + curl_easy_pause(curl, CURL_READFUNC_PAUSE | CURL_WRITEFUNC_PAUSE); + + } +} +~~~ + +# MEMORY USE + +When pausing a download transfer by returning the magic return code from a +write callback, the read data is already in libcurl's internal buffers so it +has to keep it in an allocated buffer until the receiving is again unpaused +using this function. + +If the downloaded data is compressed and is asked to get uncompressed +automatically on download, libcurl continues to uncompress the entire +downloaded chunk and it caches the data uncompressed. This has the side- +effect that if you download something that is compressed a lot, it can result +in a large data amount needing to be allocated to save the data during the +pause. Consider not using paused receiving if you allow libcurl to uncompress +data automatically. + +If the download is done with HTTP/2 or HTTP/3, there is up to a stream window +size worth of data that curl cannot stop but instead needs to cache while the +transfer is paused.

By setting the +appropriate options, the application can change libcurl's behavior. All +options are set with an *option* followed by a *parameter*. That parameter can +be a **long**, a **function pointer**, an **object pointer** or a +**curl_off_t**, depending on what the specific option expects. Read this +manual carefully as bad input values may cause libcurl to behave badly! You +can only set one option in each function call. A typical application uses many +curl_easy_setopt(3) calls in the setup phase. + +Options set with this function call are valid for all forthcoming transfers +performed using this *handle*. The options are not in any way reset between +transfers, so if you want subsequent transfers with different options, you +must change them between the transfers. You can optionally reset all options +back to internal default with curl_easy_reset(3). + +Strings passed to libcurl as 'char *' arguments, are copied by the library; +the string storage associated to the pointer argument may be discarded or +reused after curl_easy_setopt(3) returns. The only exception to this rule is +really CURLOPT_POSTFIELDS(3), but the alternative that copies the string +CURLOPT_COPYPOSTFIELDS(3) has some usage characteristics you need to read up +on. This function does not accept input strings longer than +**CURL_MAX_INPUT_LENGTH** (8 MB). + +The order in which the options are set does not matter. + +Before version 7.17.0, strings were not copied. Instead the user was forced +keep them available until libcurl no longer needed them. + +The *handle* is the return code from a curl_easy_init(3) or +curl_easy_duphandle(3) call. + +# BEHAVIOR OPTIONS + +## CURLOPT_VERBOSE + +Display verbose information.

Each part consists of at least a NAME and a CONTENTS part. If the part +is made for file upload, there are also a stored CONTENT-TYPE and a FILENAME. +Below, we discuss what options you use to set these properties in the parts +you want to add to your post. + +The options listed first are for making normal parts. The options from +*CURLFORM_FILE* through *CURLFORM_BUFFERLENGTH* are for file upload +parts. + +# OPTIONS + +## CURLFORM_COPYNAME + +followed by a string which provides the *name* of this part. libcurl +copies the string so your application does not need to keep it around after +this function call. If the name is not null-terminated, you must set its +length with **CURLFORM_NAMELENGTH**. The *name* is not allowed to +contain zero-valued bytes. The copied data is freed by curl_formfree(3). + +## CURLFORM_PTRNAME + +followed by a string which provides the *name* of this part. libcurl uses the +pointer and refer to the data in your application, so you must make sure it +remains until curl no longer needs it. If the name is not null-terminated, you +must set its length with **CURLFORM_NAMELENGTH**. The *name* is not allowed to +contain zero-valued bytes. + +## CURLFORM_COPYCONTENTS + +followed by a pointer to the contents of this part, the actual data to send +away. libcurl copies the provided data, so your application does not need to +keep it around after this function call. If the data is not null terminated, +or if you would like it to contain zero bytes, you must set the length of the +name with **CURLFORM_CONTENTSLENGTH**. The copied data is freed by +curl_formfree(3). + +## CURLFORM_PTRCONTENTS + +followed by a pointer to the contents of this part, the actual data to send +away. libcurl uses the pointer and refer to the data in your application, so +you must make sure it remains until curl no longer needs it. If the data is +not null-terminated, or if you would like it to contain zero bytes, you must +set its length with **CURLFORM_CONTENTSLENGTH**. + +## CURLFORM_CONTENTLEN + +followed by a curl_off_t value giving the length of the contents. Note that +for *CURLFORM_STREAM* contents, this option is mandatory. + +If you pass a 0 (zero) for this option, libcurl calls strlen() on the contents +to figure out the size. If you really want to send a zero byte content then +you must make sure strlen() on the data pointer returns zero. + +(Option added in 7.46.0) + +## CURLFORM_CONTENTSLENGTH + +(This option is deprecated. Use *CURLFORM_CONTENTLEN* instead!) + +followed by a long giving the length of the contents. Note that for +*CURLFORM_STREAM* contents, this option is mandatory. + +If you pass a 0 (zero) for this option, libcurl calls strlen() on the contents +to figure out the size. If you really want to send a zero byte content then +you must make sure strlen() on the data pointer returns zero. + +## CURLFORM_FILECONTENT + +followed by a filename, causes that file to be read and its contents used +as data in this part. This part does *not* automatically become a file +upload part simply because its data was read from a file. + +The specified file needs to kept around until the associated transfer is done. + +## CURLFORM_FILE + +followed by a filename, makes this part a file upload part. It sets the +*filename* field to the basename of the provided filename, it reads the +contents of the file and passes them as data and sets the content-type if the +given file match one of the internally known file extensions. For +**CURLFORM_FILE** the user may send one or more files in one part by +providing multiple **CURLFORM_FILE** arguments each followed by the filename +(and each *CURLFORM_FILE* is allowed to have a +*CURLFORM_CONTENTTYPE*). + +The given upload file has to exist in its full in the file system already when +the upload starts, as libcurl needs to read the correct file size beforehand. + +The specified file needs to kept around until the associated transfer is done. + +## CURLFORM_CONTENTTYPE + +is used in combination with *CURLFORM_FILE*. Followed by a pointer to a +string which provides the content-type for this part, possibly instead of an +internally chosen one. + +## CURLFORM_FILENAME + +is used in combination with *CURLFORM_FILE*. Followed by a pointer to a +string, it tells libcurl to use the given string as the *filename* in the file +upload part instead of the actual filename. + +## CURLFORM_BUFFER + +is used for custom file upload parts without use of *CURLFORM_FILE*. It +tells libcurl that the file contents are already present in a buffer. The +parameter is a string which provides the *filename* field in the content +header. + +## CURLFORM_BUFFERPTR + +is used in combination with *CURLFORM_BUFFER*. The parameter is a pointer +to the buffer to be uploaded. This buffer must not be freed until after +curl_easy_cleanup(3) is called. You must also use +*CURLFORM_BUFFERLENGTH* to set the number of bytes in the buffer. + +## CURLFORM_BUFFERLENGTH + +is used in combination with *CURLFORM_BUFFER*. The parameter is a +long which gives the length of the buffer. + +## CURLFORM_STREAM + +Tells libcurl to use the CURLOPT_READFUNCTION(3) callback to get +data. The parameter you pass to *CURLFORM_STREAM* is the pointer passed on +to the read callback's fourth argument. If you want the part to look like a +file upload one, set the *CURLFORM_FILENAME* parameter as well. Note that +when using *CURLFORM_STREAM*, *CURLFORM_CONTENTSLENGTH* must also be +set with the total expected length of the part unless the formpost is sent +chunked encoded. (Option added in libcurl 7.18.2) + +## CURLFORM_ARRAY + +Another possibility to send options to curl_formadd() is the +**CURLFORM_ARRAY** option, that passes a struct curl_forms array pointer as +its value. Each curl_forms structure element has a *CURLformoption* and a +char pointer. The final element in the array must be a CURLFORM_END. All +available options can be used in an array, except the CURLFORM_ARRAY option +itself. The last argument in such an array must always be **CURLFORM_END**. + +## CURLFORM_CONTENTHEADER + +specifies extra headers for the form POST section. This takes a curl_slist +prepared in the usual way using **curl_slist_append** and appends the list +of headers to those libcurl automatically generates. The list must exist while +the POST occurs, if you free it before the post completes you may experience +problems. + +When you have passed the *struct curl_httppost* pointer to +curl_easy_setopt(3) (using the CURLOPT_HTTPPOST(3) option), you +must not free the list until after you have called curl_easy_cleanup(3) +for the curl handle. + +See example below. + +# EXAMPLE + +~~~c +#include /* for strlen */ + +static const char record[]="data in a buffer"; + +int main(void) +{ + CURL *curl = curl_easy_init(); + if(curl) { + struct curl_httppost *post = NULL; + struct curl_httppost *last = NULL; + char namebuffer[] = "name buffer"; + long namelength = strlen(namebuffer); + char buffer[] = "test buffer"; + char htmlbuffer[] = "test buffer"; + long htmlbufferlength = strlen(htmlbuffer); + struct curl_forms forms[3]; + char file1[] = "my-face.jpg"; + char file2[] = "your-face.jpg"; + /* add null character into htmlbuffer, to demonstrate that + transfers of buffers containing null characters actually work + */ + htmlbuffer[8] = '\0'; + + /* Add simple name/content section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "name", + CURLFORM_COPYCONTENTS, "content", CURLFORM_END); + + /* Add simple name/content/contenttype section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "htmlcode", + CURLFORM_COPYCONTENTS, "", + CURLFORM_CONTENTTYPE, "text/html", CURLFORM_END); + + /* Add name/ptrcontent section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "name_for_ptrcontent", + CURLFORM_PTRCONTENTS, buffer, CURLFORM_END); + + /* Add ptrname/ptrcontent section */ + curl_formadd(&post, &last, CURLFORM_PTRNAME, namebuffer, + CURLFORM_PTRCONTENTS, buffer, CURLFORM_NAMELENGTH, + namelength, CURLFORM_END); + + /* Add name/ptrcontent/contenttype section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "html_code_with_hole", + CURLFORM_PTRCONTENTS, htmlbuffer, + CURLFORM_CONTENTSLENGTH, htmlbufferlength, + CURLFORM_CONTENTTYPE, "text/html", CURLFORM_END); + + /* Add simple file section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "picture", + CURLFORM_FILE, "my-face.jpg", CURLFORM_END); + + /* Add file/contenttype section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "picture", + CURLFORM_FILE, "my-face.jpg", + CURLFORM_CONTENTTYPE, "image/jpeg", CURLFORM_END); + + /* Add two file section */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "pictures", + CURLFORM_FILE, "my-face.jpg", + CURLFORM_FILE, "your-face.jpg", CURLFORM_END); + + /* Add two file section using CURLFORM_ARRAY */ + forms[0].option = CURLFORM_FILE; + forms[0].value = file1; + forms[1].option = CURLFORM_FILE; + forms[1].value = file2; + forms[2].option = CURLFORM_END; + + /* Add a buffer to upload */ + curl_formadd(&post, &last, + CURLFORM_COPYNAME, "name", + CURLFORM_BUFFER, "data", + CURLFORM_BUFFERPTR, record, + CURLFORM_BUFFERLENGTH, sizeof(record), + CURLFORM_END); + + /* no option needed for the end marker */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "pictures", + CURLFORM_ARRAY, forms, CURLFORM_END); + /* Add the content of a file as a normal post text value */ + curl_formadd(&post, &last, CURLFORM_COPYNAME, "filecontent", + CURLFORM_FILECONTENT, ".bashrc", CURLFORM_END); + /* Set the form info */ + curl_easy_setopt(curl, CURLOPT_HTTPPOST, post); + + curl_easy_perform(curl); + + curl_easy_cleanup(curl); + + curl_formfree(post); + } +} +~~~ + +# AVAILABILITY + +Deprecated in 7.56.0.

Names may be prefixed with '+' or '-' to enable +or disable detailed logging for a component. + +The list of component names is not part of curl's public API. Names may be +added or disappear in future versions of libcurl. Since unknown names are +silently ignored, outdated log configurations does not cause errors when +upgrading libcurl. Given that, some names can be expected to be fairly stable +and are listed below for easy reference. + +Note that log configuration applies only to transfers where debug logging +is enabled.

See curl_easy_pause(3) for further details. + +The seek function gets called by libcurl to rewind input stream data or to +seek to a certain position.

These functions do +not call the *va_end* macro. Because they invoke the *va_arg* macro, +the value of *ap* is undefined after the call. + +The functions **curl_maprintf()** and **curl_mvaprintf()** return the +output string as pointer to a newly allocated memory area. The returned string +must be curl_free(3)ed by the receiver. + +All of these functions write the output under the control of a format string +that specifies how subsequent arguments are converted for output. + +# FORMAT STRING + +The format string is composed of zero or more directives: ordinary characters +(not %), which are copied unchanged to the output stream; and conversion +specifications, each of which results in fetching zero or more subsequent +arguments. Each conversion specification is introduced by the character %, and +ends with a conversion specifier. In between there may be (in this order) zero +or more *flags*, an optional minimum *field width*, an optional +*precision* and an optional *length modifier*. + +# The $ modifier + +The arguments must correspond properly with the conversion specifier. By +default, the arguments are used in the order given, where each '*' (see Field +width and Precision below) and each conversion specifier asks for the next +argument (and it is an error if insufficiently many arguments are given). One +can also specify explicitly which argument is taken, at each place where an +argument is required, by writing "%m$" instead of '%' and "*m$" instead +of '*', where the decimal integer m denotes the position in the argument list +of the desired argument, indexed starting from 1. Thus, +~~~c + curl_mprintf("%*d", width, num); +~~~ +and +~~~c + curl_mprintf("%2$*1$d", width, num); +~~~ +are equivalent. The second style allows repeated references to the same +argument. + +If the style using '$' is used, it must be used throughout for all conversions +taking an argument and all width and precision arguments, but it may be mixed +with "%%" formats, which do not consume an argument. There may be no gaps in +the numbers of arguments specified using '$'; for example, if arguments 1 and +3 are specified, argument 2 must also be specified somewhere in the format +string. + +# Flag characters + +The character % is followed by zero or more of the following flags: + +## # + +The value should be converted to its "alternate form". + +## 0 + +The value should be zero padded. + +## - + +The converted value is to be left adjusted on the field boundary. (The default +is right justification.) The converted value is padded on the right with +blanks, rather than on the left with blanks or zeros. A '-' overrides a &'0' +if both are given. + +## (space) + +(a space: ' ') A blank should be left before a positive number (or empty +string) produced by a signed conversion. + +## + + +A sign (+ or -) should always be placed before a number produced by a signed +conversion. By default, a sign is used only for negative numbers. A '+' +overrides a space if both are used. + +# Field width + +An optional decimal digit string (with nonzero first digit) specifying a +minimum field width. If the converted value has fewer characters than the +field width, it gets padded with spaces on the left (or right, if the +left-adjustment flag has been given). Instead of a decimal digit string one +may write "*" or "*m$" (for some decimal integer m) to specify that the field +width is given in the next argument, or in the *m-th* argument, +respectively, which must be of type int. A negative field width is taken as +a '-' flag followed by a positive field width. In no case does a nonexistent +or small field width cause truncation of a field; if the result of a +conversion is wider than the field width, the field is expanded to contain the +conversion result. + +# Precision + +An optional precision in the form of a period ('.') followed by an optional +decimal digit string. Instead of a decimal digit string one may write "*" or +"*m$" (for some decimal integer m) to specify that the precision is given in +the next argument, or in the *m-th* argument, respectively, which must be of +type int. If the precision is given as just '.', the precision is taken to be +zero. A negative precision is taken as if the precision were omitted. This +gives the minimum number of digits to appear for **d**, **i**, **o**, +**u**, **x**, and **X** conversions, the number of digits to appear +after the radix character for **a**, **A**, **e**, **E**, **f**, and +**F** conversions, the maximum number of significant digits for **g** and +**G** conversions, or the maximum number of characters to be printed from a +string for **s** and **S** conversions. + +# Length modifier + +## h + +A following integer conversion corresponds to a *short* or *unsigned short* +argument. + +## l + +(ell) A following integer conversion corresponds to a *long* or +*unsigned long* argument, or a following n conversion corresponds to a +pointer to a long argument + +## ll + +(ell-ell).

The +conversion specifiers and their meanings are: + +## d, i + +The int argument is converted to signed decimal notation. The precision, if +any, gives the minimum number of digits that must appear; if the converted +value requires fewer digits, it is padded on the left with zeros. The default +precision is 1. When 0 is printed with an explicit precision 0, the output is +empty. + +## o, u, x, X + +The unsigned int argument is converted to unsigned octal (o), unsigned decimal +(u), or unsigned hexadecimal (**x** and **X**) notation.

There are specific man pages for each function mentioned in +here. There is also the libcurl-tutorial(3) man page for a complete +tutorial to programming with libcurl and the libcurl-easy(3) man page +for an overview of the libcurl easy interface. + +All functions in the multi interface are prefixed with curl_multi. + +# OBJECTIVES + +The multi interface offers several abilities that the easy interface does not. +They are mainly: + +1. Enable a "pull" interface. The application that uses libcurl decides where +and when to ask libcurl to get/send data. + +2. Enable multiple simultaneous transfers in the same thread without making it +complicated for the application. + +3. Enable the application to wait for action on its own file descriptors and +curl's file descriptors simultaneously. + +4. Enable event-based handling and scaling transfers up to and beyond +thousands of parallel connections. + +# ONE MULTI HANDLE MANY EASY HANDLES + +To use the multi interface, you must first create a 'multi handle' with +curl_multi_init(3). This handle is then used as input to all further +curl_multi_* functions. + +With a multi handle and the multi interface you can do several simultaneous +transfers in parallel. Each single transfer is built up around an easy +handle. You create all the easy handles you need, and setup the appropriate +options for each easy handle using curl_easy_setopt(3). + +There are two flavors of the multi interface, the select() oriented one and +the event based one we call multi_socket. You benefit from reading through the +description of both versions to fully understand how they work and +differentiate. We start out with the select() oriented version. + +When an easy handle is setup and ready for transfer, then instead of using +curl_easy_perform(3) like when using the easy interface for transfers, +you should add the easy handle to the multi handle with +curl_multi_add_handle(3). You can add more easy handles to a multi +handle at any point, even if other transfers are already running. + +Should you change your mind, the easy handle is again removed from the multi +stack using curl_multi_remove_handle(3). Once removed from the multi +handle, you can again use other easy interface functions like +curl_easy_perform(3) on the handle or whatever you think is +necessary. You can remove handles at any point during transfers. + +Adding the easy handle to the multi handle does not start the transfer. +Remember that one of the main ideas with this interface is to let your +application drive. You drive the transfers by invoking +curl_multi_perform(3). libcurl then transfers data if there is anything +available to transfer. It uses the callbacks and everything else you have +setup in the individual easy handles. It transfers data on all current +transfers in the multi stack that are ready to transfer anything. It may be +all, it may be none. When there is nothing more to do for now, it returns back +to the calling application. + +Your application extracts info from libcurl about when it would like to get +invoked to transfer data or do other work. The most convenient way is to use +curl_multi_poll(3) that helps you wait until the application should call +libcurl again. The older API to accomplish the same thing is +curl_multi_fdset(3) that extracts *fd_sets* from libcurl to use in +select() or poll() calls in order to get to know when the transfers in the +multi stack might need attention. Both these APIs allow for your program to +wait for input on your own private file descriptors at the same time. +curl_multi_timeout(3) also helps you with providing a suitable timeout +period for your select() calls. + +curl_multi_perform(3) stores the number of still running transfers in +one of its input arguments, and by reading that you can figure out when all +the transfers in the multi handles are done. 'done' does not mean +successful. One or more of the transfers may have failed. + +To get information about completed transfers, to figure out success or not and +similar, curl_multi_info_read(3) should be called. It can return a +message about a current or previous transfer. Repeated invokes of the function +get more messages until the message queue is empty. The information you +receive there includes an easy handle pointer which you may use to identify +which easy handle the information regards. + +When a single transfer is completed, the easy handle is still left added to +the multi stack. You need to first remove the easy handle with +curl_multi_remove_handle(3) and then close it with +curl_easy_cleanup(3), or possibly set new options to it and add it again +with curl_multi_add_handle(3) to start another transfer. + +When all transfers in the multi stack are done, close the multi handle with +curl_multi_cleanup(3). Be careful and please note that you **MUST** +invoke separate curl_easy_cleanup(3) calls for every single easy handle +to clean them up properly. + +If you want to reuse an easy handle that was added to the multi handle for +transfer, you must first remove it from the multi stack and then re-add it +again (possibly after having altered some options at your own choice). + +# MULTI_SOCKET + +curl_multi_socket_action(3) function offers a way for applications to +not only avoid being forced to use select(), but it also offers a much more +high-performance API that makes a significant difference for applications +using large numbers of simultaneous connections. + +curl_multi_socket_action(3) is then used instead of +curl_multi_perform(3). + +When using this API, you add easy handles to the multi handle just as with the +normal multi interface. Then you also set two callbacks with the +CURLMOPT_SOCKETFUNCTION(3) and CURLMOPT_TIMERFUNCTION(3) options +to curl_multi_setopt(3). They are two callback functions that libcurl +calls with information about what sockets to wait for, and for what activity, +and what the current timeout time is - if that expires libcurl should be +notified. + +The multi_socket API is designed to inform your application about which +sockets libcurl is currently using and for what activities (read and/or write) +on those sockets your application is expected to wait for. + +Your application must make sure to receive all sockets informed about in the +CURLMOPT_SOCKETFUNCTION(3) callback and make sure it reacts on the given +activity on them. When a socket has the given activity, you call +curl_multi_socket_action(3) specifying which socket and action there +are. + +The CURLMOPT_TIMERFUNCTION(3) callback is called to set a timeout. When +that timeout expires, your application should call the +curl_multi_socket_action(3) function saying it was due to a timeout. + +This API is typically used with an event-driven underlying functionality (like +libevent, libev, kqueue, epoll or similar) with which the application +"subscribes" on socket changes. This allows applications and libcurl to much +better scale upward and beyond thousands of simultaneous transfers without +losing performance. + +When you have added your initial set of handles, you call +curl_multi_socket_action(3) with CURL_SOCKET_TIMEOUT set in the +*sockfd* argument, and you get callbacks invoked that set you up and you +then continue to call curl_multi_socket_action(3) accordingly when you +get activity on the sockets you have been asked to wait on, or if the timeout +timer expires. + +You can poll curl_multi_info_read(3) to see if any transfer has +completed, as it then has a message saying so. + +# BLOCKING + +A few areas in the code are still using blocking code, even when used from the +multi interface.

The library is written with +caution and precautions are taken to mitigate many kinds of risks encountered +while operating with potentially malicious servers on the Internet. It is a +powerful library, however, which allows application writers to make trade-offs +between ease of writing and exposure to potential risky operations. If used +the right way, you can use libcurl to transfer data pretty safely. + +Many applications are used in closed networks where users and servers can +(possibly) be trusted, but many others are used on arbitrary servers and are +fed input from potentially untrusted users. Following is a discussion about +some risks in the ways in which applications commonly use libcurl and +potential mitigations of those risks. It is not comprehensive, but shows +classes of attacks that robust applications should consider. The Common +Weakness Enumeration project at https://cwe.mitre.org/ is a good reference for +many of these and similar types of weaknesses of which application writers +should be aware. + +# Command Lines + +If you use a command line tool (such as curl) that uses libcurl, and you give +options to the tool on the command line those options can get read by other +users of your system when they use *ps* or other tools to list currently +running processes. + +To avoid these problems, never feed sensitive things to programs using command +line options. Write them to a protected file and use the -K option to avoid +this. + +# .netrc + +.netrc is a pretty handy file/feature that allows you to login quickly and +automatically to frequently visited sites. The file contains passwords in +clear text and is a real security risk. In some cases, your .netrc is also +stored in a home directory that is NFS mounted or used on another network +based file system, so the clear text password flies through your network every +time anyone reads that file. + +For applications that enable .netrc use, a user who manage to set the right +URL might then be possible to pass on passwords. + +To avoid these problems, do not use .netrc files and never store passwords in +plain text anywhere. + +# Clear Text Passwords + +Many of the protocols libcurl supports send name and password unencrypted as +clear text (HTTP Basic authentication, FTP, TELNET etc). It is easy for anyone +on your network or a network nearby yours to just fire up a network analyzer +tool and eavesdrop on your passwords. Do not let the fact that HTTP Basic uses +base64 encoded passwords fool you. They may not look readable at a first +glance, but they are easily "deciphered" by anyone within seconds. + +To avoid this problem, use an authentication mechanism or other protocol that +does not let snoopers see your password: Digest, CRAM-MD5, Kerberos, SPNEGO or +NTLM authentication. Or even better: use authenticated protocols that protect +the entire connection and everything sent over it. + +# Unauthenticated Connections + +Protocols that do not have any form of cryptographic authentication cannot +with any certainty know that they communicate with the right remote server. + +If your application is using a fixed scheme or fixed hostname, it is not safe +as long as the connection is unauthenticated. There can be a man-in-the-middle +or in fact the whole server might have been replaced by an evil actor. + +Unauthenticated protocols are unsafe. The data that comes back to curl may +have been injected by an attacker. The data that curl sends might be modified +before it reaches the intended server. If it even reaches the intended server +at all. + +Remedies: + +## Restrict operations to authenticated transfers + +Use authenticated protocols protected with HTTPS or SSH. + +## Make sure the server's certificate etc is verified + +Never ever switch off certificate verification. + +# Redirects + +The CURLOPT_FOLLOWLOCATION(3) option automatically follows HTTP +redirects sent by a remote server. These redirects can refer to any kind of +URL, not just HTTP. libcurl restricts the protocols allowed to be used in +redirects for security reasons: only HTTP, HTTPS, FTP and FTPS are +enabled by default. Applications may opt to restrict that set further. + +A redirect to a file: URL would cause the libcurl to read (or write) arbitrary +files from the local filesystem. If the application returns the data back to +the user (as would happen in some kinds of CGI scripts), an attacker could +leverage this to read otherwise forbidden data (e.g. +**file://localhost/etc/passwd**). + +If authentication credentials are stored in the ~/.netrc file, or Kerberos is +in use, any other URL type (not just file:) that requires authentication is +also at risk. A redirect such as **ftp://some-internal-server/private-file** would +then return data even when the server is password protected. + +In the same way, if an unencrypted SSH private key has been configured for the +user running the libcurl application, SCP: or SFTP: URLs could access password +or private-key protected resources, +e.g. **sftp://user@some-internal-server/etc/passwd** + +The CURLOPT_REDIR_PROTOCOLS(3) and CURLOPT_NETRC(3) options can be +used to mitigate against this kind of attack. + +A redirect can also specify a location available only on the machine running +libcurl, including servers hidden behind a firewall from the attacker. +E.g. **http://127.0.0.1/** or **http://intranet/delete-stuff.cgi?delete=all** or +**tftp://bootp-server/pc-config-data** + +Applications can mitigate against this by disabling +CURLOPT_FOLLOWLOCATION(3) and handling redirects itself, sanitizing URLs +as necessary. Alternately, an app could leave CURLOPT_FOLLOWLOCATION(3) +enabled but set CURLOPT_REDIR_PROTOCOLS(3) and install a +CURLOPT_OPENSOCKETFUNCTION(3) or CURLOPT_PREREQFUNCTION(3) callback +function in which addresses are sanitized before use. + +# CRLF in Headers + +For all options in libcurl which specify headers, including but not limited to +CURLOPT_HTTPHEADER(3), CURLOPT_PROXYHEADER(3), +CURLOPT_COOKIE(3), CURLOPT_USERAGENT(3), CURLOPT_REFERER(3) +and CURLOPT_RANGE(3), libcurl sends the headers as-is and does not apply +any special sanitation or normalization to them. + +If you allow untrusted user input into these options without sanitizing CRLF +sequences in them, someone malicious may be able to modify the request in a +way you did not intend such as injecting new headers. + +# Local Resources + +A user who can control the DNS server of a domain being passed in within a URL +can change the address of the host to a local, private address which a +server-side libcurl-using application could then use. E.g. the innocuous URL +**http://fuzzybunnies.example.com/** could actually resolve to the IP +address of a server behind a firewall, such as 127.0.0.1 or +10.1.2.3. Applications can mitigate against this by setting a +CURLOPT_OPENSOCKETFUNCTION(3) or CURLOPT_PREREQFUNCTION(3) and +checking the address before a connection. + +All the malicious scenarios regarding redirected URLs apply just as well to +non-redirected URLs, if the user is allowed to specify an arbitrary URL that +could point to a private resource. For example, a web app providing a +translation service might happily translate **file://localhost/etc/passwd** +and display the result. Applications can mitigate against this with the +CURLOPT_PROTOCOLS(3) option as well as by similar mitigation techniques +for redirections. + +A malicious FTP server could in response to the PASV command return an IP +address and port number for a server local to the app running libcurl but +behind a firewall. Applications can mitigate against this by using the +CURLOPT_FTP_SKIP_PASV_IP(3) option or CURLOPT_FTPPORT(3). + +Local servers sometimes assume local access comes from friends and trusted +users. An application that expects https://example.com/file_to_read that and +instead gets http://192.168.0.1/my_router_config might print a file that would +otherwise be protected by the firewall. + +Allowing your application to connect to local hosts, be it the same machine +that runs the application or a machine on the same local network, might be +possible to exploit by an attacker who then perhaps can "port-scan" the +particular hosts - depending on how the application and servers acts. + +# IPv4 Addresses + +Some users might be tempted to filter access to local resources or similar +based on numerical IPv4 addresses used in URLs. This is a bad and error-prone +idea because of the many different ways a numerical IPv4 address can be +specified and libcurl accepts: one to four dot-separated fields using one of +or a mix of decimal, octal or hexadecimal encoding. + +# IPv6 Addresses + +libcurl handles IPv6 addresses transparently and just as easily as IPv4 +addresses. That means that a sanitizing function that filters out addresses +like 127.0.0.1 is not sufficient - the equivalent IPv6 addresses **::1**, +**::**, **0:00::0:1**, **::127.0.0.1** and **::ffff:7f00:1** supplied +somehow by an attacker would all bypass a naive filter and could allow access +to undesired local resources. IPv6 also has special address blocks like +link-local and site-local that generally should not be accessed by a +server-side libcurl-using application. A poorly configured firewall installed +in a data center, organization or server may also be configured to limit IPv4 +connections but leave IPv6 connections wide open. In some cases, setting +CURLOPT_IPRESOLVE(3) to CURL_IPRESOLVE_V4 can be used to limit resolved +addresses to IPv4 only and bypass these issues. + +# Uploads + +When uploading, a redirect can cause a local (or remote) file to be +overwritten. Applications must not allow any unsanitized URL to be passed in +for uploads. Also, CURLOPT_FOLLOWLOCATION(3) should not be used on +uploads. Instead, the applications should consider handling redirects itself, +sanitizing each URL first. + +# Authentication + +Use of CURLOPT_UNRESTRICTED_AUTH(3) could cause authentication +information to be sent to an unknown second server. Applications can mitigate +against this by disabling CURLOPT_FOLLOWLOCATION(3) and handling +redirects itself, sanitizing where necessary. + +Use of the CURLAUTH_ANY option to CURLOPT_HTTPAUTH(3) could result in +user name and password being sent in clear text to an HTTP server. Instead, +use CURLAUTH_ANYSAFE which ensures that the password is encrypted over the +network, or else fail the request. + +Use of the CURLUSESSL_TRY option to CURLOPT_USE_SSL(3) could result in +user name and password being sent in clear text to an FTP server. Instead, +use CURLUSESSL_CONTROL to ensure that an encrypted connection is used or else +fail the request. + +# Cookies + +If cookies are enabled and cached, then a user could craft a URL which +performs some malicious action to a site whose authentication is already +stored in a cookie. E.g. +**http://mail.example.com/delete-stuff.cgi?delete=all** Applications can +mitigate against this by disabling cookies or clearing them between requests. + +# Dangerous SCP URLs + +SCP URLs can contain raw commands within the scp: URL, which is a side effect +of how the SCP protocol is designed. E.g. +~~~ + scp://user:pass@host/a;date >/tmp/test; +~~~ +Applications must not allow unsanitized SCP: URLs to be passed in for +downloads. + +# file:// + +By default curl and libcurl support file:// URLs. Such a URL is always an +access, or attempted access, to a local resource. If your application wants to +avoid that, keep control of what URLs to use and/or prevent curl/libcurl from +using the protocol. + +By default, libcurl prohibits redirects to file:// URLs. + +# Warning: file:// on Windows + +The Windows operating system tries automatically, and without any way for +applications to disable it, to establish a connection to another host over the +network and access it (over SMB or other protocols), if only the correct file +path is accessed. + +When first realizing this, the curl team tried to filter out such attempts in +order to protect applications for inadvertent probes of for example internal +networks etc. This resulted in CVE-2019-15601 and the associated security fix. + +However, we have since been made aware of the fact that the previous fix was far +from adequate as there are several other ways to accomplish more or less the +same thing: accessing a remote host over the network instead of the local file +system. + +The conclusion we have come to is that this is a weakness or feature in the +Windows operating system itself, that we as an application cannot safely +protect users against. It would just be a whack-a-mole race we do not want to +participate in. There are too many ways to do it and there is no knob we can +use to turn off the practice. + +If you use curl or libcurl on Windows (any version), disable the use of the +FILE protocol in curl or be prepared that accesses to a range of "magic paths" +potentially make your system access other hosts on your network. curl cannot +protect you against this. + +# What if the user can set the URL + +Applications may find it tempting to let users set the URL that it can work +on. That is probably fine, but opens up for mischief and trickery that you as +an application author may want to address or take precautions against. + +If your curl-using script allow a custom URL do you also, perhaps +unintentionally, allow the user to pass other options to the curl command line +if creative use of special characters are applied? + +If the user can set the URL, the user can also specify the scheme part to +other protocols that you did not intend for users to use and perhaps did not +consider. curl supports over 20 different URL schemes. "http://" might be what +you thought, "ftp://" or "imap://" might be what the user gives your +application. Also, cross-protocol operations might be done by using a +particular scheme in the URL but point to a server doing a different protocol +on a non-standard port. + +Remedies: + +## Use --proto + +curl command lines can use *--proto* to limit what URL schemes it accepts + +## Use CURLOPT_PROTOCOLS + +libcurl programs can use CURLOPT_PROTOCOLS(3) to limit what URL schemes it accepts + +## consider not allowing the user to set the full URL + +Maybe just let the user provide data for parts of it? Or maybe filter input to +only allow specific choices? + +# RFC 3986 vs WHATWG URL + +curl supports URLs mostly according to how they are defined in RFC 3986, and +has done so since the beginning. + +Web browsers mostly adhere to the WHATWG URL Specification. + +This deviance makes some URLs copied between browsers (or returned over HTTP +for redirection) and curl not work the same way. It can also cause problems if +an application parses URLs differently from libcurl and makes different +assumptions about a link. This can mislead users into getting the wrong thing, +connecting to the wrong host or otherwise not working identically. + +Within an application, this can be mitigated by always using the +curl_url(3) API to parse URLs, ensuring that they are parsed the same way +as within libcurl itself. + +# FTP uses two connections + +When performing an FTP transfer, two TCP connections are used: one for setting +up the transfer and one for the actual data. + +FTP is not only unauthenticated, but the setting up of the second transfer is +also a weak spot. The second connection to use for data, is either setup with +the PORT/EPRT command that makes the server connect back to the client on the +given IP+PORT, or with PASV/EPSV that makes the server setup a port to listen +to and tells the client to connect to a given IP+PORT. + +Again, unauthenticated means that the connection might be meddled with by a +man-in-the-middle or that there is a malicious server pretending to be the +right one. + +A malicious FTP server can respond to PASV commands with the IP+PORT of a +totally different machine. Perhaps even a third party host, and when there are +many clients trying to connect to that third party, it could create a +Distributed Denial-Of-Service attack out of it. If the client makes an upload +operation, it can make the client send the data to another site. If the +attacker can affect what data the client uploads, it can be made to work as a +HTTP request and then the client could be made to issue HTTP requests to third +party hosts. + +An attacker that manages to control curl's command line options can tell curl +to send an FTP PORT command to ask the server to connect to a third party host +instead of back to curl. + +The fact that FTP uses two connections makes it vulnerable in a way that is +hard to avoid. + +# Denial of Service + +A malicious server could cause libcurl to effectively hang by sending data +slowly, or even no data at all but just keeping the TCP connection open. This +could effectively result in a denial-of-service attack. The +CURLOPT_TIMEOUT(3) and/or CURLOPT_LOW_SPEED_LIMIT(3) options can +be used to mitigate against this. + +A malicious server could cause libcurl to download an infinite amount of data, +potentially causing all of memory or disk to be filled. Setting the +CURLOPT_MAXFILESIZE_LARGE(3) option is not sufficient to guard against +this. Instead, applications should monitor the amount of data received within +the write or progress callback and abort once the limit is reached. + +A malicious HTTP server could cause an infinite redirection loop, causing a +denial-of-service. This can be mitigated by using the +CURLOPT_MAXREDIRS(3) option. + +# Arbitrary Headers + +User-supplied data must be sanitized when used in options like +CURLOPT_USERAGENT(3), CURLOPT_HTTPHEADER(3), +CURLOPT_POSTFIELDS(3) and others that are used to generate structured +data. Characters like embedded carriage returns or ampersands could allow the +user to create additional headers or fields that could cause malicious +transactions. + +# Server-supplied Names + +A server can supply data which the application may, in some cases, use as a +filename. The curl command-line tool does this with *--remote-header-name*, +using the Content-disposition: header to generate a filename. An application +could also use CURLINFO_EFFECTIVE_URL(3) to generate a filename from a +server-supplied redirect URL. Special care must be taken to sanitize such +names to avoid the possibility of a malicious server supplying one like +**"/etc/passwd"**, **"autoexec.bat"**, **"prn:"** or even **".bashrc"**. + +# Server Certificates + +A secure application should never use the CURLOPT_SSL_VERIFYPEER(3) +option to disable certificate validation. There are numerous attacks that are +enabled by applications that fail to properly validate server TLS/SSL +certificates, thus enabling a malicious server to spoof a legitimate +one. HTTPS without validated certificates is potentially as insecure as a +plain HTTP connection. + +# Showing What You Do + +Relatedly, be aware that in situations when you have problems with libcurl and +ask someone for help, everything you reveal in order to get best possible help +might also impose certain security related risks. Host names, user names, +paths, operating system specifics, etc. (not to mention passwords of course) +may in fact be used by intruders to gain additional information of a potential +target. + +Be sure to limit access to application logs if they could hold private or +security-related data. Besides the obvious candidates like user names and +passwords, things like URLs, cookies or even file names could also hold +sensitive data. + +To avoid this problem, you must of course use your common sense. Often, you +can just edit out the sensitive data or just search/replace your true +information with faked data. + +# setuid applications using libcurl + +libcurl-using applications that set the 'setuid' bit to run with elevated or +modified rights also implicitly give that extra power to libcurl and this +should only be done after careful considerations. + +Giving setuid powers to the application means that libcurl can save files using +those new rights (if for example the `SSLKEYLOGFILE` environment variable is +set). Also: if the application wants these powers to read or manage secrets +that the user is otherwise not able to view (like credentials for a login +etc), it should be noted that libcurl still might understand proxy environment +variables that allow the user to redirect libcurl operations to use a proxy +controlled by the user. + +# File descriptors, fork and NTLM + +An application that uses libcurl and invokes *fork()* gets all file +descriptors duplicated in the child process, including the ones libcurl +created. + +libcurl itself uses *fork()* and *execl()* if told to use the +**CURLAUTH_NTLM_WB** authentication method which then invokes the helper +command in a child process with file descriptors duplicated. Make sure that +only the trusted and reliable helper program is invoked! + +# Secrets in memory + +When applications pass user names, passwords or other sensitive data to +libcurl to be used for upcoming transfers, those secrets are kept around as-is +in memory. In many cases they are stored in the heap for as long as the handle +itself for which the options are set. + +If an attacker can access the heap, like maybe by reading swap space or via a +core dump file, such data might be accessible. + +Further, when eventually closing a handle and the secrets are no longer +needed, libcurl does not explicitly clear memory before freeing it, so +credentials may be left in freed data. + +# Saving files + +libcurl cannot protect against attacks where an attacker has write access to +the same directory where libcurl is directed to save files. + +# Cookies + +If libcurl is built with PSL (**Public Suffix List**) support, it detects and +discards cookies that are specified for such suffix domains that should not be +allowed to have cookies. + +if libcurl is *not* built with PSL support, it has no ability to stop super +cookies. + +# Report Security Problems + +Should you detect or just suspect a security problem in libcurl or curl, +contact the project curl security team immediately.

Some operating systems are known to have faulty thread +implementations. We have previously received problem reports on *BSD (at least +in the past, they may be working fine these days). Some operating systems that +are known to have solid and working thread support are Linux, Solaris and +Windows. + +# curl_global_* functions + +These functions are thread-safe since libcurl 7.84.0 if +curl_version_info(3) has the **CURL_VERSION_THREADSAFE** feature bit +set (most platforms). + +If these functions are not thread-safe and you are using libcurl with multiple +threads it is especially important that before use you call +curl_global_init(3) or curl_global_init_mem(3) to explicitly +initialize the library and its dependents, rather than rely on the "lazy" +fail-safe initialization that takes place the first time +curl_easy_init(3) is called. For an in-depth explanation refer to +libcurl(3) section **GLOBAL CONSTANTS**. + +# Memory functions + +These functions, provided either by your operating system or your own +replacements, must be thread safe.

The text focuses on the +C interface but should apply fairly well on other language bindings as well as +they usually follow the C API pretty closely. + +This document refers to 'the user' as the person writing the source code that +uses libcurl. That would probably be you or someone in your position. What is +generally referred to as 'the program' is the collected source code that you +write that is using libcurl for transfers. The program is outside libcurl and +libcurl is outside of the program. + +To get more details on all options and functions described herein, please +refer to their respective man pages. + +# Building + +There are many different ways to build C programs. This chapter assumes a Unix +style build process. If you use a different build system, you can still read +this to get general information that may apply to your environment as well. + +## Compiling the Program + +Your compiler needs to know where the libcurl headers are located. Therefore +you must set your compiler's include path to point to the directory where you +installed them. The 'curl-config'[3] tool can be used to get this information: +~~~c + $ curl-config --cflags +~~~ + +## Linking the Program with libcurl + +When having compiled the program, you need to link your object files to create +a single executable. For that to succeed, you need to link with libcurl and +possibly also with other libraries that libcurl itself depends on. Like the +OpenSSL libraries, but even some standard OS libraries may be needed on the +command line. To figure out which flags to use, once again the 'curl-config' +tool comes to the rescue: +~~~c + $ curl-config --libs +~~~ + +## SSL or Not + +libcurl can be built and customized in many ways. One of the things that +varies from different libraries and builds is the support for SSL-based +transfers, like HTTPS and FTPS. If a supported SSL library was detected +properly at build-time, libcurl is built with SSL support. To figure out if an +installed libcurl has been built with SSL support enabled, use *curl-config* +like this: + +~~~c + $ curl-config --feature +~~~ + +If SSL is supported, the keyword *SSL* is written to stdout, possibly together +with a other features that could be either on or off on for different +libcurls. + +See also the "Features libcurl Provides" further down. + +## autoconf macro + +When you write your configure script to detect libcurl and setup variables +accordingly, we offer a macro that probably does everything you need in this +area. See docs/libcurl/libcurl.m4 file - it includes docs on how to use it. + +# Portable Code in a Portable World + +The people behind libcurl have put a considerable effort to make libcurl work +on a large amount of different operating systems and environments. + +You program libcurl the same way on all platforms that libcurl runs on. There +are only a few minor details that differ. If you just make sure to write your +code portable enough, you can create a portable program. libcurl should not +stop you from that. + +# Global Preparation + +The program must initialize some of the libcurl functionality globally. That +means it should be done exactly once, no matter how many times you intend to +use the library. Once for your program's entire life time. This is done using +~~~c + curl_global_init() +~~~ +and it takes one parameter which is a bit pattern that tells libcurl what to +initialize. Using *CURL_GLOBAL_ALL* makes it initialize all known internal +sub modules, and might be a good default option. The current two bits that are +specified are: + +## CURL_GLOBAL_WIN32 + +which only does anything on Windows machines. When used on a Windows machine, +it makes libcurl initialize the win32 socket stuff. Without having that +initialized properly, your program cannot use sockets properly. You should +only do this once for each application, so if your program already does this +or of another library in use does it, you should not tell libcurl to do this +as well. + +## CURL_GLOBAL_SSL + +which only does anything on libcurls compiled and built SSL-enabled. On these +systems, this makes libcurl initialize the SSL library properly for this +application. This only needs to be done once for each application so if your +program or another library already does this, this bit should not be needed. + +libcurl has a default protection mechanism that detects if +curl_global_init(3) has not been called by the time +curl_easy_perform(3) is called and if that is the case, libcurl runs the +function itself with a guessed bit pattern. Please note that depending solely +on this is not considered nice nor good. + +When the program no longer uses libcurl, it should call +curl_global_cleanup(3), which is the opposite of the init call. It +performs the reversed operations to cleanup the resources the +curl_global_init(3) call initialized. + +Repeated calls to curl_global_init(3) and curl_global_cleanup(3) +should be avoided. They should only be called once each. + +# Features libcurl Provides + +It is considered best-practice to determine libcurl features at runtime rather +than at build-time (if possible of course). By calling +curl_version_info(3) and checking out the details of the returned +struct, your program can figure out exactly what the currently running libcurl +supports. + +# Two Interfaces + +libcurl first introduced the so called easy interface. All operations in the +easy interface are prefixed with 'curl_easy'. The easy interface lets you do +single transfers with a synchronous and blocking function call. + +libcurl also offers another interface that allows multiple simultaneous +transfers in a single thread, the so called multi interface. More about that +interface is detailed in a separate chapter further down. You still need to +understand the easy interface first, so please continue reading for better +understanding. + +# Handle the Easy libcurl + +To use the easy interface, you must first create yourself an easy handle. You +need one handle for each easy session you want to perform. Basically, you +should use one handle for every thread you plan to use for transferring. You +must never share the same handle in multiple threads. + +Get an easy handle with +~~~c + handle = curl_easy_init(); +~~~ +It returns an easy handle. Using that you proceed to the next step: setting +up your preferred actions. A handle is just a logic entity for the upcoming +transfer or series of transfers. + +You set properties and options for this handle using +curl_easy_setopt(3). They control how the subsequent transfer or +transfers using this handle are made. Options remain set in the handle until +set again to something different. They are sticky. Multiple requests using the +same handle use the same options. + +If you at any point would like to blank all previously set options for a +single easy handle, you can call curl_easy_reset(3) and you can also +make a clone of an easy handle (with all its set options) using +curl_easy_duphandle(3). + +Many of the options you set in libcurl are "strings", pointers to data +terminated with a zero byte. When you set strings with +curl_easy_setopt(3), libcurl makes its own copy so that they do not need +to be kept around in your application after being set[4]. + +One of the most basic properties to set in the handle is the URL. You set your +preferred URL to transfer with CURLOPT_URL(3) in a manner similar to: + +~~~c + curl_easy_setopt(handle, CURLOPT_URL, "http://domain.com/"); +~~~ + +Let's assume for a while that you want to receive data as the URL identifies a +remote resource you want to get here. Since you write a sort of application +that needs this transfer, I assume that you would like to get the data passed +to you directly instead of simply getting it passed to stdout. So, you write +your own function that matches this prototype: +~~~c + size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp); +~~~ +You tell libcurl to pass all data to this function by issuing a function +similar to this: +~~~c + curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, write_data); +~~~ +You can control what data your callback function gets in the fourth argument +by setting another property: +~~~c + curl_easy_setopt(handle, CURLOPT_WRITEDATA, &internal_struct); +~~~ +Using that property, you can easily pass local data between your application +and the function that gets invoked by libcurl. libcurl itself does not touch +the data you pass with CURLOPT_WRITEDATA(3). + +libcurl offers its own default internal callback that takes care of the data +if you do not set the callback with CURLOPT_WRITEFUNCTION(3). It simply +outputs the received data to stdout. You can have the default callback write +the data to a different file handle by passing a 'FILE *' to a file opened for +writing with the CURLOPT_WRITEDATA(3) option. + +Now, we need to take a step back and take a deep breath. Here is one of those +rare platform-dependent nitpicks. Did you spot it? On some platforms[2], +libcurl is not able to operate on file handles opened by the +program. Therefore, if you use the default callback and pass in an open file +handle with CURLOPT_WRITEDATA(3), libcurl crashes. You should avoid this +to make your program run fine virtually everywhere. + +(CURLOPT_WRITEDATA(3) was formerly known as *CURLOPT_FILE*. Both names still +work and do the same thing). + +If you are using libcurl as a win32 DLL, you MUST use the +CURLOPT_WRITEFUNCTION(3) if you set CURLOPT_WRITEDATA(3) - or experience +crashes. + +There are of course many more options you can set, and we get back to a few of +them later. Let's instead continue to the actual transfer: + +~~~c + success = curl_easy_perform(handle); +~~~ + +curl_easy_perform(3) connects to the remote site, does the necessary commands +and performs the transfer. Whenever it receives data, it calls the callback +function we previously set. The function may get one byte at a time, or it may +get many kilobytes at once. libcurl delivers as much as possible as often as +possible. Your callback function should return the number of bytes it "took +care of". If that is not the same amount of bytes that was passed to it, +libcurl aborts the operation and returns with an error code. + +When the transfer is complete, the function returns a return code that informs +you if it succeeded in its mission or not. If a return code is not enough for +you, you can use the CURLOPT_ERRORBUFFER(3) to point libcurl to a buffer of +yours where it stores a human readable error message as well. + +If you then want to transfer another file, the handle is ready to be used +again. It is even preferred and encouraged that you reuse an existing handle +if you intend to make another transfer. libcurl then attempts to reuse a +previous connection. + +For some protocols, downloading a file can involve a complicated process of +logging in, setting the transfer mode, changing the current directory and +finally transferring the file data. libcurl takes care of all that +complication for you. Given simply the URL to a file, libcurl takes care of +all the details needed to get the file moved from one machine to another. + +# Multi-threading Issues + +libcurl is thread safe but there are a few exceptions. Refer to +libcurl-thread(3) for more information. + +# When It does not Work + +There are times when the transfer fails for some reason. You might have set +the wrong libcurl option or misunderstood what the libcurl option actually +does, or the remote server might return non-standard replies that confuse the +library which then confuses your program. + +There is one golden rule when these things occur: set the +CURLOPT_VERBOSE(3) option to 1. it causes the library to spew out the +entire protocol details it sends, some internal info and some received +protocol data as well (especially when using FTP). If you are using HTTP, +adding the headers in the received output to study is also a clever way to get +a better understanding why the server behaves the way it does. Include headers +in the normal body output with CURLOPT_HEADER(3) set 1. + +Of course, there are bugs left. We need to know about them to be able to fix +them, so we are quite dependent on your bug reports. When you do report +suspected bugs in libcurl, please include as many details as you possibly can: +a protocol dump that CURLOPT_VERBOSE(3) produces, library version, as +much as possible of your code that uses libcurl, operating system name and +version, compiler name and version etc. + +If CURLOPT_VERBOSE(3) is not enough, you increase the level of debug +data your application receive by using the CURLOPT_DEBUGFUNCTION(3). + +Getting some in-depth knowledge about the protocols involved is never wrong, +and if you are trying to do funny things, you might understand libcurl and how +to use it better if you study the appropriate RFC documents at least briefly. + +# Upload Data to a Remote Site + +libcurl tries to keep a protocol independent approach to most transfers, thus +uploading to a remote FTP site is similar to uploading data to an HTTP server +with a PUT request. + +Of course, first you either create an easy handle or you reuse one existing +one. Then you set the URL to operate on just like before. This is the remote +URL, that we now upload. + +Since we write an application, we most likely want libcurl to get the upload +data by asking us for it. To make it do that, we set the read callback and the +custom pointer libcurl passes to our read callback. The read callback should +have a prototype similar to: +~~~c + size_t function(char *bufptr, size_t size, size_t nitems, void *userp); +~~~ +Where *bufptr* is the pointer to a buffer we fill in with data to upload +and *size*nitems* is the size of the buffer and therefore also the maximum +amount of data we can return to libcurl in this call. The *userp* pointer +is the custom pointer we set to point to a struct of ours to pass private data +between the application and the callback. +~~~c + curl_easy_setopt(handle, CURLOPT_READFUNCTION, read_function); + + curl_easy_setopt(handle, CURLOPT_READDATA, &filedata); +~~~ +Tell libcurl that we want to upload: +~~~c + curl_easy_setopt(handle, CURLOPT_UPLOAD, 1L); +~~~ +A few protocols do not behave properly when uploads are done without any prior +knowledge of the expected file size. So, set the upload file size using the +CURLOPT_INFILESIZE_LARGE(3) for all known file sizes like this[1]: + +~~~c + /* in this example, file_size must be an curl_off_t variable */ + curl_easy_setopt(handle, CURLOPT_INFILESIZE_LARGE, file_size); +~~~ + +When you call curl_easy_perform(3) this time, it performs all the +necessary operations and when it has invoked the upload it calls your supplied +callback to get the data to upload. The program should return as much data as +possible in every invoke, as that is likely to make the upload perform as fast +as possible. The callback should return the number of bytes it wrote in the +buffer. Returning 0 signals the end of the upload. + +# Passwords + +Many protocols use or even require that user name and password are provided +to be able to download or upload the data of your choice. libcurl offers +several ways to specify them. + +Most protocols support that you specify the name and password in the URL +itself. libcurl detects this and use them accordingly. This is written like +this: +~~~c + protocol://user:password@example.com/path/ +~~~ +If you need any odd letters in your user name or password, you should enter +them URL encoded, as %XX where XX is a two-digit hexadecimal number. + +libcurl also provides options to set various passwords. The user name and +password as shown embedded in the URL can instead get set with the +CURLOPT_USERPWD(3) option. The argument passed to libcurl should be a +char * to a string in the format "user:password". In a manner like this: + +~~~c + curl_easy_setopt(handle, CURLOPT_USERPWD, "myname:thesecret"); +~~~ + +Another case where name and password might be needed at times, is for those +users who need to authenticate themselves to a proxy they use. libcurl offers +another option for this, the CURLOPT_PROXYUSERPWD(3). It is used quite similar +to the CURLOPT_USERPWD(3) option like this: + +~~~c + curl_easy_setopt(handle, CURLOPT_PROXYUSERPWD, "myname:thesecret"); +~~~ + +There is a long time Unix "standard" way of storing FTP user names and +passwords, namely in the $HOME/.netrc file (on Windows, libcurl also checks +the *%USERPROFILE% environment* variable if *%HOME%* is unset, and tries +"_netrc" as name). The file should be made private so that only the user may +read it (see also the "Security Considerations" chapter), as it might contain +the password in plain text. libcurl has the ability to use this file to figure +out what set of user name and password to use for a particular host. As an +extension to the normal functionality, libcurl also supports this file for +non-FTP protocols such as HTTP. To make curl use this file, use the +CURLOPT_NETRC(3) option: + +~~~c + curl_easy_setopt(handle, CURLOPT_NETRC, 1L); +~~~ + +A basic example of how such a .netrc file may look like: + +~~~c + machine myhost.mydomain.com + login userlogin + password secretword +~~~ + +All these examples have been cases where the password has been optional, or +at least you could leave it out and have libcurl attempt to do its job +without it. There are times when the password is not optional, like when +you are using an SSL private key for secure transfers. + +To pass the known private key password to libcurl: +~~~c + curl_easy_setopt(handle, CURLOPT_KEYPASSWD, "keypassword"); +~~~ + +# HTTP Authentication + +The previous chapter showed how to set user name and password for getting URLs +that require authentication. When using the HTTP protocol, there are many +different ways a client can provide those credentials to the server and you +can control which way libcurl uses them. The default HTTP authentication +method is called 'Basic', which is sending the name and password in clear-text +in the HTTP request, base64-encoded. This is insecure. + +At the time of this writing, libcurl can be built to use: Basic, Digest, NTLM, +Negotiate (SPNEGO). You can tell libcurl which one to use with +CURLOPT_HTTPAUTH(3) as in: + +~~~c + curl_easy_setopt(handle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST); + +~~~ + +When you send authentication to a proxy, you can also set authentication type +the same way but instead with CURLOPT_PROXYAUTH(3): + +~~~c + curl_easy_setopt(handle, CURLOPT_PROXYAUTH, CURLAUTH_NTLM); +~~~ + +Both these options allow you to set multiple types (by ORing them together), +to make libcurl pick the most secure one out of the types the server/proxy +claims to support. This method does however add a round-trip since libcurl +must first ask the server what it supports: + +~~~c + curl_easy_setopt(handle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST|CURLAUTH_BASIC); +~~~ + +For convenience, you can use the *CURLAUTH_ANY* define (instead of a list with +specific types) which allows libcurl to use whatever method it wants. + +When asking for multiple types, libcurl picks the available one it considers +"best" in its own internal order of preference. + +# HTTP POSTing + +We get many questions regarding how to issue HTTP POSTs with libcurl the +proper way. This chapter thus includes examples using both different versions +of HTTP POST that libcurl supports. + +The first version is the simple POST, the most common version, that most HTML +pages using the
tag uses. We provide a pointer to the data and tell +libcurl to post it all to the remote site: + +~~~c + char *data="name=daniel&project=curl"; + curl_easy_setopt(handle, CURLOPT_POSTFIELDS, data); + curl_easy_setopt(handle, CURLOPT_URL, "http://posthere.com/"); + + curl_easy_perform(handle); /* post away! */ +~~~ + +Simple enough, huh? Since you set the POST options with the +CURLOPT_POSTFIELDS(3), this automatically switches the handle to use +POST in the upcoming request. + +What if you want to post binary data that also requires you to set the +Content-Type: header of the post? Well, binary posts prevent libcurl from being +able to do strlen() on the data to figure out the size, so therefore we must +tell libcurl the size of the post data. Setting headers in libcurl requests are +done in a generic way, by building a list of our own headers and then passing +that list to libcurl. + +~~~c + struct curl_slist *headers=NULL; + headers = curl_slist_append(headers, "Content-Type: text/xml"); + + /* post binary data */ + curl_easy_setopt(handle, CURLOPT_POSTFIELDS, binaryptr); + + /* set the size of the postfields data */ + curl_easy_setopt(handle, CURLOPT_POSTFIELDSIZE, 23L); + + /* pass our list of custom made headers */ + curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers); + + curl_easy_perform(handle); /* post away! */ + + curl_slist_free_all(headers); /* free the header list */ +~~~ + +While the simple examples above cover the majority of all cases where HTTP +POST operations are required, they do not do multi-part formposts. Multi-part +formposts were introduced as a better way to post (possibly large) binary data +and were first documented in the RFC 1867 (updated in RFC 2388). They are +called multi-part because they are built by a chain of parts, each part being +a single unit of data. Each part has its own name and contents. You can in +fact create and post a multi-part formpost with the regular libcurl POST +support described above, but that would require that you build a formpost +yourself and provide to libcurl. + +To make that easier, libcurl provides a MIME API consisting in several +functions: using those, you can create and fill a multi-part form. Function +curl_mime_init(3) creates a multi-part body; you can then append new parts +to a multi-part body using curl_mime_addpart(3). + +There are three possible data sources for a part: memory using +curl_mime_data(3), file using curl_mime_filedata(3) and user-defined data +read callback using curl_mime_data_cb(3). curl_mime_name(3) sets a part's +(i.e.: form field) name, while curl_mime_filename(3) fills in the remote +filename. With curl_mime_type(3), you can tell the MIME type of a part, +curl_mime_headers(3) allows defining the part's headers. When a multi-part +body is no longer needed, you can destroy it using curl_mime_free(3). + +The following example sets two simple text parts with plain textual contents, +and then a file with binary contents and uploads the whole thing. + +~~~c + curl_mime *multipart = curl_mime_init(handle); + curl_mimepart *part = curl_mime_addpart(multipart); + curl_mime_name(part, "name"); + curl_mime_data(part, "daniel", CURL_ZERO_TERMINATED); + part = curl_mime_addpart(multipart); + curl_mime_name(part, "project"); + curl_mime_data(part, "curl", CURL_ZERO_TERMINATED); + part = curl_mime_addpart(multipart); + curl_mime_name(part, "logotype-image"); + curl_mime_filedata(part, "curl.png"); + + /* Set the form info */ + curl_easy_setopt(handle, CURLOPT_MIMEPOST, multipart); + + curl_easy_perform(handle); /* post away! */ + + /* free the post data again */ + curl_mime_free(multipart); +~~~ + +To post multiple files for a single form field, you must supply each file in +a separate part, all with the same field name. Although function +curl_mime_subparts(3) implements nested multi-parts, this way of +multiple files posting is deprecated by RFC 7578, chapter 4.3. + +To set the data source from an already opened FILE pointer, use: + +~~~c + curl_mime_data_cb(part, filesize, (curl_read_callback) fread, + (curl_seek_callback) fseek, NULL, filepointer); +~~~ + +A deprecated curl_formadd(3) function is still supported in libcurl. +It should however not be used anymore for new designs and programs using it +ought to be converted to the MIME API. It is however described here as an +aid to conversion. + +Using *curl_formadd*, you add parts to the form. When you are done adding +parts, you post the whole form. + +The MIME API example above is expressed as follows using this function: + +~~~c + struct curl_httppost *post=NULL; + struct curl_httppost *last=NULL; + curl_formadd(&post, &last, + CURLFORM_COPYNAME, "name", + CURLFORM_COPYCONTENTS, "daniel", CURLFORM_END); + curl_formadd(&post, &last, + CURLFORM_COPYNAME, "project", + CURLFORM_COPYCONTENTS, "curl", CURLFORM_END); + curl_formadd(&post, &last, + CURLFORM_COPYNAME, "logotype-image", + CURLFORM_FILECONTENT, "curl.png", CURLFORM_END); + + /* Set the form info */ + curl_easy_setopt(handle, CURLOPT_HTTPPOST, post); + + curl_easy_perform(handle); /* post away! */ + + /* free the post data again */ + curl_formfree(post); +~~~ + +Multipart formposts are chains of parts using MIME-style separators and +headers. It means that each one of these separate parts get a few headers set +that describe the individual content-type, size etc. To enable your +application to handicraft this formpost even more, libcurl allows you to +supply your own set of custom headers to such an individual form part. You can +of course supply headers to as many parts as you like, but this little example +shows how you set headers to one specific part when you add that to the post +handle: + +~~~c + struct curl_slist *headers=NULL; + headers = curl_slist_append(headers, "Content-Type: text/xml"); + + curl_formadd(&post, &last, + CURLFORM_COPYNAME, "logotype-image", + CURLFORM_FILECONTENT, "curl.xml", + CURLFORM_CONTENTHEADER, headers, + CURLFORM_END); + + curl_easy_perform(handle); /* post away! */ + + curl_formfree(post); /* free post */ + curl_slist_free_all(headers); /* free custom header list */ +~~~ + +Since all options on an easy handle are "sticky", they remain the same until +changed even if you do call curl_easy_perform(3), you may need to tell +curl to go back to a plain GET request if you intend to do one as your next +request. You force an easy handle to go back to GET by using the +CURLOPT_HTTPGET(3) option: +~~~c + curl_easy_setopt(handle, CURLOPT_HTTPGET, 1L); +~~~ +Just setting CURLOPT_POSTFIELDS(3) to "" or NULL does *not* stop libcurl +from doing a POST.

This option is set to 1 by default. + +For most applications however, the built-in progress meter is useless and what +instead is interesting is the ability to specify a progress callback. The +function pointer you pass to libcurl is then called on irregular intervals +with information about the current transfer. + +Set the progress callback by using CURLOPT_PROGRESSFUNCTION(3). Pass a pointer +to a function that matches this prototype: + +~~~c + int progress_callback(void *clientp, + double dltotal, + double dlnow, + double ultotal, + double ulnow); +~~~ + +If any of the input arguments is unknown, a 0 is provided. The first argument, +the 'clientp' is the pointer you pass to libcurl with +CURLOPT_PROGRESSDATA(3). libcurl does not touch it. + +# libcurl with C++ + +There is basically only one thing to keep in mind when using C++ instead of C +when interfacing libcurl: + +The callbacks CANNOT be non-static class member functions + +Example C++ code: + +~~~c +class AClass { + static size_t write_data(void *ptr, size_t size, size_t nmemb, + void *ourpointer) + { + /* do what you want with the data */ + } + } +~~~ + +# Proxies + +What "proxy" means according to Merriam-Webster: "a person authorized to act +for another" but also "the agency, function, or office of a deputy who acts as +a substitute for another". + +Proxies are exceedingly common these days. Companies often only offer Internet +access to employees through their proxies. Network clients or user-agents ask +the proxy for documents, the proxy does the actual request and then it returns +them. + +libcurl supports SOCKS and HTTP proxies. When a given URL is wanted, libcurl +asks the proxy for it instead of trying to connect to the actual remote host +identified in the URL. + +If you are using a SOCKS proxy, you may find that libcurl does not quite support +all operations through it. + +For HTTP proxies: the fact that the proxy is an HTTP proxy puts certain +restrictions on what can actually happen. A requested URL that might not be a +HTTP URL is passed to the HTTP proxy to deliver back to libcurl. This happens +transparently, and an application may not need to know. I say "may", because +at times it is important to understand that all operations over an HTTP proxy +use the HTTP protocol. For example, you cannot invoke your own custom FTP +commands or even proper FTP directory listings. + +## Proxy Options + +To tell libcurl to use a proxy at a given port number: +~~~c + curl_easy_setopt(handle, CURLOPT_PROXY, "proxy-host.com:8080"); +~~~ +Some proxies require user authentication before allowing a request, and you +pass that information similar to this: +~~~c + curl_easy_setopt(handle, CURLOPT_PROXYUSERPWD, "user:password"); +~~~ +If you want to, you can specify the hostname only in the +CURLOPT_PROXY(3) option, and set the port number separately with +CURLOPT_PROXYPORT(3). + +Tell libcurl what kind of proxy it is with CURLOPT_PROXYTYPE(3) (if not, +it defaults to assuming an HTTP proxy): +~~~c + curl_easy_setopt(handle, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS4); +~~~ + +## Environment Variables + +libcurl automatically checks and uses a set of environment variables to know +what proxies to use for certain protocols. The names of the variables are +following an old tradition and are built up as "[protocol]_proxy" (note the +lower casing). Which makes the variable 'http_proxy' checked for a name of a +proxy to use when the input URL is HTTP. Following the same rule, the variable +named 'ftp_proxy' is checked for FTP URLs. Again, the proxies are always HTTP +proxies, the different names of the variables simply allows different HTTP +proxies to be used. + +The proxy environment variable contents should be in the format +"[protocol://][user:password@]machine[:port]". Where the protocol:// part +specifies which type of proxy it is, and the optional port number specifies on +which port the proxy operates. If not specified, the internal default port +number is used and that is most likely not the one you would like it to be. + +There are two special environment variables. 'all_proxy' is what sets proxy +for any URL in case the protocol specific variable was not set, and 'no_proxy' +defines a list of hosts that should not use a proxy even though a variable may +say so. If 'no_proxy' is a plain asterisk ("*") it matches all hosts. + +To explicitly disable libcurl's checking for and using the proxy environment +variables, set the proxy name to "" - an empty string - with +CURLOPT_PROXY(3). + +## SSL and Proxies + +SSL is for secure point-to-point connections. This involves strong encryption +and similar things, which effectively makes it impossible for a proxy to +operate as a "man in between" which the proxy's task is, as previously +discussed. Instead, the only way to have SSL work over an HTTP proxy is to ask +the proxy to tunnel everything through without being able to check or fiddle +with the traffic. + +Opening an SSL connection over an HTTP proxy is therefore a matter of asking the +proxy for a straight connection to the target host on a specified port. This +is made with the HTTP request CONNECT. ("please dear proxy, connect me to that +remote host"). + +Because of the nature of this operation, where the proxy has no idea what kind +of data that is passed in and out through this tunnel, this breaks some of the +few advantages that come from using a proxy, such as caching. Many +organizations prevent this kind of tunneling to other destination port numbers +than 443 (which is the default HTTPS port number). + +## Tunneling Through Proxy + +As explained above, tunneling is required for SSL to work and often even +restricted to the operation intended for SSL; HTTPS. + +This is however not the only time proxy-tunneling might offer benefits to +you or your application. + +As tunneling opens a direct connection from your application to the remote +machine, it suddenly also re-introduces the ability to do non-HTTP +operations over an HTTP proxy. You can in fact use things such as FTP +upload or FTP custom commands this way. + +Again, this is often prevented by the administrators of proxies and is +rarely allowed. + +Tell libcurl to use proxy tunneling like this: +~~~c + curl_easy_setopt(handle, CURLOPT_HTTPPROXYTUNNEL, 1L); +~~~ +In fact, there might even be times when you want to do plain HTTP operations +using a tunnel like this, as it then enables you to operate on the remote +server instead of asking the proxy to do so. libcurl does not stand in the way +for such innovative actions either! + +## Proxy Auto-Config + +Netscape first came up with this. It is basically a webpage (usually using a +.pac extension) with a JavaScript that when executed by the browser with the +requested URL as input, returns information to the browser on how to connect +to the URL. The returned information might be "DIRECT" (which means no proxy +should be used), "PROXY host:port" (to tell the browser where the proxy for +this particular URL is) or "SOCKS host:port" (to direct the browser to a SOCKS +proxy). + +libcurl has no means to interpret or evaluate JavaScript and thus it does not +support this. If you get yourself in a position where you face this nasty +invention, the following advice have been mentioned and used in the past: + +- Depending on the JavaScript complexity, write up a script that translates it +to another language and execute that. + +- Read the JavaScript code and rewrite the same logic in another language. + +- Implement a JavaScript interpreter; people have successfully used the +Mozilla JavaScript engine in the past. + +- Ask your admins to stop this, for a static proxy setup or similar. + +# Persistence Is The Way to Happiness + +Re-cycling the same easy handle several times when doing multiple requests is +the way to go. + +After each single curl_easy_perform(3) operation, libcurl keeps the +connection alive and open. A subsequent request using the same easy handle to +the same host might just be able to use the already open connection! This +reduces network impact a lot. + +Even if the connection is dropped, all connections involving SSL to the same +host again, benefit from libcurl's session ID cache that drastically reduces +re-connection time. + +FTP connections that are kept alive save a lot of time, as the command- +response round-trips are skipped, and also you do not risk getting blocked +without permission to login again like on many FTP servers only allowing N +persons to be logged in at the same time. + +libcurl caches DNS name resolving results, to make lookups of a previously +looked up name a lot faster. + +Other interesting details that improve performance for subsequent requests +may also be added in the future. + +Each easy handle attempts to keep the last few connections alive for a while +in case they are to be used again. You can set the size of this "cache" with +the CURLOPT_MAXCONNECTS(3) option. Default is 5. There is rarely any +point in changing this value, and if you think of changing this it is often +just a matter of thinking again. + +To force your upcoming request to not use an already existing connection, you +can do that by setting CURLOPT_FRESH_CONNECT(3) to 1. In a similar +spirit, you can also forbid the upcoming request to be "lying" around and +possibly get reused after the request by setting +CURLOPT_FORBID_REUSE(3) to 1. + +# HTTP Headers Used by libcurl + +When you use libcurl to do HTTP requests, it passes along a series of headers +automatically. It might be good for you to know and understand these. You can +replace or remove them by using the CURLOPT_HTTPHEADER(3) option. + +## Host + +This header is required by HTTP 1.1 and even many 1.0 servers and should be +the name of the server we want to talk to. This includes the port number if +anything but default. + +## Accept + +"*/*" + +## Expect + +When doing POST requests, libcurl sets this header to "100-continue" to ask +the server for an "OK" message before it proceeds with sending the data part +of the post. If the posted data amount is deemed "small", libcurl does not use +this header. + +# Customizing Operations + +There is an ongoing development today where more and more protocols are built +upon HTTP for transport. This has obvious benefits as HTTP is a tested and +reliable protocol that is widely deployed and has excellent proxy-support. + +When you use one of these protocols, and even when doing other kinds of +programming you may need to change the traditional HTTP (or FTP or...) +manners. You may need to change words, headers or various data. + +libcurl is your friend here too. + +## CUSTOMREQUEST + +If just changing the actual HTTP request keyword is what you want, like when +GET, HEAD or POST is not good enough for you, CURLOPT_CUSTOMREQUEST(3) +is there for you. It is simple to use: +~~~c +curl_easy_setopt(handle, CURLOPT_CUSTOMREQUEST, "MYOWNREQUEST"); +~~~ +When using the custom request, you change the request keyword of the actual +request you are performing. Thus, by default you make a GET request but you +can also make a POST operation (as described before) and then replace the POST +keyword if you want to. You are the boss. + +## Modify Headers + +HTTP-like protocols pass a series of headers to the server when doing the +request, and you are free to pass any amount of extra headers that you +think fit. Adding headers is this easy: + +~~~c +struct curl_slist *headers=NULL; /* init to NULL is important */ + +headers = curl_slist_append(headers, "Hey-server-hey: how are you?"); +headers = curl_slist_append(headers, "X-silly-content: yes"); + +/* pass our list of custom made headers */ +curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers); + +curl_easy_perform(handle); /* transfer http */ + +curl_slist_free_all(headers); /* free the header list */ +~~~ + +... and if you think some of the internally generated headers, such as Accept: +or Host: do not contain the data you want them to contain, you can replace +them by simply setting them too: + +~~~c +headers = curl_slist_append(headers, "Accept: Agent-007"); +headers = curl_slist_append(headers, "Host: munged.host.line"); +~~~ + +## Delete Headers + +If you replace an existing header with one with no contents, you prevent the +header from being sent. For instance, if you want to completely prevent the +"Accept:" header from being sent, you can disable it with code similar to +this: + + headers = curl_slist_append(headers, "Accept:"); + +Both replacing and canceling internal headers should be done with careful +consideration and you should be aware that you may violate the HTTP protocol +when doing so. + +## Enforcing chunked transfer-encoding + +By making sure a request uses the custom header "Transfer-Encoding: chunked" +when doing a non-GET HTTP operation, libcurl switches over to "chunked" +upload, even though the size of the data to upload might be known. By default, +libcurl usually switches over to chunked upload automatically if the upload +data size is unknown. + +## HTTP Version + +All HTTP requests includes the version number to tell the server which version +we support. libcurl speaks HTTP 1.1 by default. Some old servers do not like +getting 1.1-requests and when dealing with stubborn old things like that, you +can tell libcurl to use 1.0 instead by doing something like this: + + curl_easy_setopt(handle, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); + +## FTP Custom Commands + +Not all protocols are HTTP-like, and thus the above may not help you when +you want to make, for example, your FTP transfers to behave differently. + +Sending custom commands to an FTP server means that you need to send the +commands exactly as the FTP server expects them (RFC 959 is a good guide +here), and you can only use commands that work on the control-connection +alone. All kinds of commands that require data interchange and thus need a +data-connection must be left to libcurl's own judgment. Also be aware that +libcurl does its best to change directory to the target directory before doing +any transfer, so if you change directory (with CWD or similar) you might +confuse libcurl and then it might not attempt to transfer the file in the +correct remote directory. + +A little example that deletes a given file before an operation: + +~~~c + headers = curl_slist_append(headers, "DELE file-to-remove"); + + /* pass the list of custom commands to the handle */ + curl_easy_setopt(handle, CURLOPT_QUOTE, headers); + + curl_easy_perform(handle); /* transfer ftp data! */ + + curl_slist_free_all(headers); /* free the header list */ +~~~ + +If you would instead want this operation (or chain of operations) to happen +_after_ the data transfer took place the option to curl_easy_setopt(3) +would instead be called CURLOPT_POSTQUOTE(3) and used the exact same +way. + +The custom FTP commands are issued to the server in the same order they are +added to the list, and if a command gets an error code returned back from the +server, no more commands are issued and libcurl bails out with an error code +(CURLE_QUOTE_ERROR). Note that if you use CURLOPT_QUOTE(3) to send +commands before a transfer, no transfer actually takes place when a quote +command has failed. + +If you set the CURLOPT_HEADER(3) to 1, you tell libcurl to get +information about the target file and output "headers" about it. The headers +are in "HTTP-style", looking like they do in HTTP. + +The option to enable headers or to run custom FTP commands may be useful to +combine with CURLOPT_NOBODY(3). If this option is set, no actual file +content transfer is performed. + +## FTP Custom CUSTOMREQUEST + +If you do want to list the contents of an FTP directory using your own defined +FTP command, CURLOPT_CUSTOMREQUEST(3) does just that. "NLST" is the +default one for listing directories but you are free to pass in your idea of a +good alternative. + +# Cookies Without Chocolate Chips + +In the HTTP sense, a cookie is a name with an associated value. A server sends +the name and value to the client, and expects it to get sent back on every +subsequent request to the server that matches the particular conditions +set. The conditions include that the domain name and path match and that the +cookie has not become too old. + +In real-world cases, servers send new cookies to replace existing ones to +update them. Server use cookies to "track" users and to keep "sessions". + +Cookies are sent from server to clients with the header Set-Cookie: and +they are sent from clients to servers with the Cookie: header. + +To just send whatever cookie you want to a server, you can use +CURLOPT_COOKIE(3) to set a cookie string like this: +~~~c + curl_easy_setopt(handle, CURLOPT_COOKIE, "name1=var1; name2=var2;"); +~~~ +In many cases, that is not enough. You might want to dynamically save +whatever cookies the remote server passes to you, and make sure those cookies +are then used accordingly on later requests. + +One way to do this, is to save all headers you receive in a plain file and +when you make a request, you tell libcurl to read the previous headers to +figure out which cookies to use. Set the header file to read cookies from with +CURLOPT_COOKIEFILE(3). + +The CURLOPT_COOKIEFILE(3) option also automatically enables the cookie +parser in libcurl. Until the cookie parser is enabled, libcurl does not parse +or understand incoming cookies and they are just be ignored. However, when the +parser is enabled the cookies are understood and the cookies are kept in +memory and used properly in subsequent requests when the same handle is +used. Many times this is enough, and you may not have to save the cookies to +disk at all. Note that the file you specify to CURLOPT_COOKIEFILE(3) +does not have to exist to enable the parser, so a common way to just enable +the parser and not read any cookies is to use the name of a file you know does +not exist. + +If you would rather use existing cookies that you have previously received +with your Netscape or Mozilla browsers, you can make libcurl use that cookie +file as input. The CURLOPT_COOKIEFILE(3) is used for that too, as +libcurl automatically finds out what kind of file it is and acts accordingly. + +Perhaps the most advanced cookie operation libcurl offers, is saving the +entire internal cookie state back into a Netscape/Mozilla formatted cookie +file. We call that the cookie-jar. When you set a filename with +CURLOPT_COOKIEJAR(3), that filename is created and all received cookies get +stored in it when curl_easy_cleanup(3) is called. This enables cookies to get +passed on properly between multiple handles without any information getting +lost. + +# FTP Peculiarities We Need + +FTP transfers use a second TCP/IP connection for the data transfer. This is +usually a fact you can forget and ignore but at times this detail comes back +to haunt you. libcurl offers several different ways to customize how the +second connection is being made. + +libcurl can either connect to the server a second time or tell the server to +connect back to it. The first option is the default and it is also what works +best for all the people behind firewalls, NATs or IP-masquerading setups. +libcurl then tells the server to open up a new port and wait for a second +connection. This is by default attempted with EPSV first, and if that does not +work it tries PASV instead. (EPSV is an extension to the original FTP spec +and does not exist nor work on all FTP servers.) + +You can prevent libcurl from first trying the EPSV command by setting +CURLOPT_FTP_USE_EPSV(3) to zero. + +In some cases, you want to have the server connect back to you for the second +connection. This might be when the server is perhaps behind a firewall or +something and only allows connections on a single port. libcurl then informs +the remote server which IP address and port number to connect to. This is made +with the CURLOPT_FTPPORT(3) option. If you set it to "-", libcurl uses your +system's "default IP address". If you want to use a particular IP, you can set +the full IP address, a hostname to resolve to an IP address or even a local +network interface name that libcurl gets the IP address from. + +When doing the "PORT" approach, libcurl attempts to use the EPRT and the LPRT +before trying PORT, as they work with more protocols. You can disable this +behavior by setting CURLOPT_FTP_USE_EPRT(3) to zero. + +# MIME API revisited for SMTP and IMAP + +In addition to support HTTP multi-part form fields, the MIME API can be used +to build structured email messages and send them via SMTP or append such +messages to IMAP directories. + +A structured email message may contain several parts: some are displayed +inline by the MUA, some are attachments. Parts can also be structured as +multi-part, for example to include another email message or to offer several +text formats alternatives. This can be nested to any level. + +To build such a message, you prepare the nth-level multi-part and then include +it as a source to the parent multi-part using function +curl_mime_subparts(3). Once it has been +bound to its parent multi-part, a nth-level multi-part belongs to it and +should not be freed explicitly. + +Email messages data is not supposed to be non-ascii and line length is +limited: fortunately, some transfer encodings are defined by the standards to +support the transmission of such incompatible data. Function +curl_mime_encoder(3) tells a part that its source data must be encoded +before being sent. It also generates the corresponding header for that part. +If the part data you want to send is already encoded in such a scheme, do not +use this function (this would over-encode it), but explicitly set the +corresponding part header. + +Upon sending such a message, libcurl prepends it with the header list +set with CURLOPT_HTTPHEADER(3), as zero level mime part headers. + +Here is an example building an email message with an inline plain/html text +alternative and a file attachment encoded in base64: + +~~~c + curl_mime *message = curl_mime_init(handle); + + /* The inline part is an alternative proposing the html and the text + versions of the email. */ + curl_mime *alt = curl_mime_init(handle); + + /* HTML message. */ + curl_mimepart *part = curl_mime_addpart(alt); + curl_mime_data(part, "

This is HTML

", + CURL_ZERO_TERMINATED); + curl_mime_type(part, "text/html"); + + /* Text message. */ + part = curl_mime_addpart(alt); + curl_mime_data(part, "This is plain text message", + CURL_ZERO_TERMINATED); + + /* Create the inline part. */ + part = curl_mime_addpart(message); + curl_mime_subparts(part, alt); + curl_mime_type(part, "multipart/alternative"); + struct curl_slist *headers = curl_slist_append(NULL, + "Content-Disposition: inline"); + curl_mime_headers(part, headers, TRUE); + + /* Add the attachment. */ + part = curl_mime_addpart(message); + curl_mime_filedata(part, "manual.pdf"); + curl_mime_encoder(part, "base64"); + + /* Build the mail headers. */ + headers = curl_slist_append(NULL, "From: me@example.com"); + headers = curl_slist_append(headers, "To: you@example.com"); + + /* Set these into the easy handle. */ + curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers); + curl_easy_setopt(handle, CURLOPT_MIMEPOST, mime); +~~~ + +It should be noted that appending a message to an IMAP directory requires +the message size to be known prior upload. It is therefore not possible to +include parts with unknown data size in this context. + +# Headers Equal Fun + +Some protocols provide "headers", meta-data separated from the normal +data. These headers are by default not included in the normal data stream, but +you can make them appear in the data stream by setting CURLOPT_HEADER(3) +to 1. + +What might be even more useful, is libcurl's ability to separate the headers +from the data and thus make the callbacks differ. You can for example set a +different pointer to pass to the ordinary write callback by setting +CURLOPT_HEADERDATA(3). + +Or, you can set an entirely separate function to receive the headers, by using +CURLOPT_HEADERFUNCTION(3). + +The headers are passed to the callback function one by one, and you can +depend on that fact. It makes it easier for you to add custom header parsers +etc. + +"Headers" for FTP transfers equal all the FTP server responses. They are not +actually true headers, but in this case we pretend they are! ;-) + +# Post Transfer Information + +See curl_easy_getinfo(3). + +# The multi Interface + +The easy interface as described in detail in this document is a synchronous +interface that transfers one file at a time and does not return until it is +done. + +The multi interface, on the other hand, allows your program to transfer +multiple files in both directions at the same time, without forcing you to use +multiple threads. The name might make it seem that the multi interface is for +multi-threaded programs, but the truth is almost the reverse. The multi +interface allows a single-threaded application to perform the same kinds of +multiple, simultaneous transfers that multi-threaded programs can perform. It +allows many of the benefits of multi-threaded transfers without the complexity +of managing and synchronizing many threads. + +To complicate matters somewhat more, there are even two versions of the multi +interface. The event based one, also called multi_socket and the "normal one" +designed for using with select(). See the libcurl-multi.3 man page for details +on the multi_socket event based API, this description here is for the select() +oriented one. + +To use this interface, you are better off if you first understand the basics +of how to use the easy interface. The multi interface is simply a way to make +multiple transfers at the same time by adding up multiple easy handles into +a "multi stack". + +You create the easy handles you want, one for each concurrent transfer, and +you set all the options just like you learned above, and then you create a +multi handle with curl_multi_init(3) and add all those easy handles to +that multi handle with curl_multi_add_handle(3). + +When you have added the handles you have for the moment (you can still add new +ones at any time), you start the transfers by calling +curl_multi_perform(3). + +curl_multi_perform(3) is asynchronous. It only performs what can be done +now and then return control to your program. It is designed to never +block. You need to keep calling the function until all transfers are +completed. + +The best usage of this interface is when you do a select() on all possible +file descriptors or sockets to know when to call libcurl again. This also +makes it easy for you to wait and respond to actions on your own application's +sockets/handles. You figure out what to select() for by using +curl_multi_fdset(3), that fills in a set of *fd_set* variables for +you with the particular file descriptors libcurl uses for the moment. + +When you then call select(), it returns when one of the file handles signal +action and you then call curl_multi_perform(3) to allow libcurl to do +what it wants to do. Take note that libcurl does also feature some time-out +code so we advise you to never use long timeouts on select() before you call +curl_multi_perform(3) again. curl_multi_timeout(3) is provided to +help you get a suitable timeout period. + +Another precaution you should use: always call curl_multi_fdset(3) +immediately before the select() call since the current set of file descriptors +may change in any curl function invoke. + +If you want to stop the transfer of one of the easy handles in the stack, you +can use curl_multi_remove_handle(3) to remove individual easy +handles. Remember that easy handles should be curl_easy_cleanup(3)ed. + +When a transfer within the multi stack has finished, the counter of running +transfers (as filled in by curl_multi_perform(3)) decreases. When the +number reaches zero, all transfers are done. + +curl_multi_info_read(3) can be used to get information about completed +transfers.

If +you are using the easy interface, you can still share these between specific +easy handles by using the share interface, see libcurl-share(3). + +Some things are never shared automatically, not within multi handles, like for +example cookies so the only way to share that is with the share interface. + +# Footnotes + +## [1] + +libcurl 7.10.3 and later have the ability to switch over to chunked +Transfer-Encoding in cases where HTTP uploads are done with data of an unknown +size. + +## [2] + +This happens on Windows machines when libcurl is built and used as a +DLL.

It is done by +upgrading a regular HTTP(S) GET request to a WebSocket connection. + +WebSocket is a TCP-like message-based communication protocol done over HTTP, +specified in RFC 6455. + +To initiate a WebSocket session with libcurl, setup an easy handle to use a +URL with a "WS://" or "WSS://" scheme. "WS" is for cleartext communication +over HTTP and "WSS" is for doing WebSocket securely over HTTPS. + +A WebSocket request is done as an HTTP/1 GET request with an "Upgrade +WebSocket" request header field. When the upgrade is accepted by the server, +it responds with a 101 Switching and then the client can speak WebSocket with +the server. The communication can happen in both directions at the same time. + +# MESSAGES + +WebSocket communication is message based. That means that both ends send and +receive entire messages, not streams like TCP. A WebSocket message is sent +over the wire in one or more frames. Each frame in a message can have a size +up to 2^63 bytes. + +libcurl delivers WebSocket data as frame fragments. It might send a whole +frame, but it might also deliver them in pieces depending on size and network +patterns. It makes sure to provide the API user about the exact specifics +about the fragment: type, offset, size and how much data there is pending to +arrive for the same frame. + +A message has an unknown size until the last frame header for the message has +been received since only frames have set sizes. + +# Raw mode + +libcurl can be told to speak WebSocket in "raw mode" by setting the +**CURLWS_RAW_MODE** bit to the CURLOPT_WS_OPTIONS(3) option. + +Raw WebSocket means that libcurl passes on the data from the network without +parsing it leaving that entirely to the application. This mode assumes that +the user of this knows WebSocket and can parse and figure out the data all by +itself. + +This mode is intended for applications that already have a WebSocket +parser/engine that want to switch over to use libcurl for enabling WebSocket, +and keep parts of the existing software architecture. + +# PING + +WebSocket is designed to allow long-lived sessions and in order to keep the +connections alive, both ends can send PING messages for the other end to +respond with a PONG. + +libcurl automatically responds to server PING messages with a PONG. It does +not send any PING messages automatically. + +# MODELS + +Because of the many different ways WebSocket can be used, which is much more +flexible than limited to plain downloads or uploads, libcurl offers two +different API models to use it: + +1. Using a write callback with CURLOPT_WRITEFUNCTION(3) much like other +downloads for when the traffic is download oriented. + +2. Using CURLOPT_CONNECT_ONLY(3) and use the WebSocket recv/send +functions. + +# Callback model + +When a write callback is set and a WebSocket transfer is performed, the +callback is called to deliver all WebSocket data that arrives. + +The callback can then call curl_ws_meta(3) to learn about the details of +the incoming data fragment. + +# CONNECT_ONLY model + +By setting CURLOPT_CONNECT_ONLY(3) to **2L**, the transfer only +establishes and setups the WebSocket communication and then returns control +back to the application. + +Once such a setup has been successfully performed, the application can proceed +and use curl_ws_recv(3) and curl_ws_send(3) freely to exchange +WebSocket messages with the server. + +# AVAILABILITY + +The WebSocket API was introduced as experimental in 7.86.0 and is still +experimental today. + +It is only built-in if explicitly opted in at build time. We discourage use of +the WebSocket API in production because of its experimental state. We might +change API, ABI and behavior before this "goes live". diff --git a/src/ext/curl/docs/libcurl/libcurl.m4 b/src/ext/curl/docs/libcurl/libcurl.m4 new file mode 100644 index 00000000..e4a518b5 --- /dev/null +++ b/src/ext/curl/docs/libcurl/libcurl.m4 @@ -0,0 +1,274 @@ +#*************************************************************************** +# _ _ ____ _ +# Project ___| | | | _ \| | +# / __| | | | |_) | | +# | (__| |_| | _ <| |___ +# \___|\___/|_| \_\_____| +# +# Copyright (C) David Shaw +# +# This software is licensed as described in the file COPYING, which +# you should have received as part of this distribution.

Look elsewhere for documentation on those. + +# TRANSFERS + +To transfer files, you create an "easy handle" using curl_easy_init(3) +for a single individual transfer (in either direction). You then set your +desired set of options in that handle with curl_easy_setopt(3). Options +you set with curl_easy_setopt(3) stick. They are then used for every +repeated use of this handle until you either change the option, or you reset +them all with curl_easy_reset(3). + +To actually transfer data you have the option of using the "easy" interface, +or the "multi" interface. + +The easy interface is a synchronous interface with which you call +curl_easy_perform(3) and let it perform the transfer. When it is +completed, the function returns and you can continue. More details are found in +the libcurl-easy(3) man page. + +The multi interface on the other hand is an asynchronous interface, that you +call and that performs only a little piece of the transfer on each invoke. It +is perfect if you want to do things while the transfer is in progress, or +similar. The multi interface allows you to select() on libcurl action, and +even to easily download multiple files simultaneously using a single +thread. See further details in the libcurl-multi(3) man page. + +# SUPPORT INTERFACES + +There is also a series of other helpful functions and interface families to +use, including these: + +## curl_version_info() + +gets detailed libcurl (and other used libraries) version info. See +curl_version_info(3) + +## curl_getdate() + +converts a date string to time_t. See curl_getdate(3) + +## curl_easy_getinfo() + +get information about a performed transfer.

See curl_slist_append(3) + +## Sharing data between transfers + +You can have multiple easy handles share certain data, even if they are used +in different threads. This magic is setup using the share interface, as +described in the libcurl-share(3) man page. + +## URL Parsing + +URL parsing and manipulations. See libcurl-url(3) + +## WebSocket communication + +See libcurl-ws(3) + +# LINKING WITH LIBCURL + +On unix-like machines, there is a tool named curl-config that gets installed +with the rest of the curl stuff when 'make install' is performed. + +curl-config is added to make it easier for applications to link with libcurl +and developers to learn about libcurl and how to use it. + +Run 'curl-config --libs' to get the (additional) linker options you need to +link with the particular version of libcurl you have installed. See the +*curl-config(1)* man page for further details. + +Unix-like operating system that ship libcurl as part of their distributions +often do not provide the curl-config tool, but simply install the library and +headers in the common path for this purpose. + +Many Linux and similar systems use pkg-config to provide build and link +options about libraries and libcurl supports that as well. + +# LIBCURL SYMBOL NAMES + +All public functions in the libcurl interface are prefixed with 'curl_' (with +a lowercase c). You can find other functions in the library source code, but +other prefixes indicate that the functions are private and may change without +further notice in the next release. + +Only use documented functions and functionality! + +# PORTABILITY + +libcurl works +**exactly** +the same, on any of the platforms it compiles and builds on. + +# THREADS + +libcurl is thread safe but there are a few exceptions. Refer to +libcurl-thread(3) for more information. + +# PERSISTENT CONNECTIONS + +Persistent connections means that libcurl can reuse the same connection for +several transfers, if the conditions are right. + +libcurl always attempts to use persistent connections. Whenever you use +curl_easy_perform(3) or curl_multi_perform(3) etc, libcurl +attempts to use an existing connection to do the transfer, and if none exists +it opens a new one that is subject for reuse on a possible following call to +curl_easy_perform(3) or curl_multi_perform(3). + +To allow libcurl to take full advantage of persistent connections, you should +do as many of your file transfers as possible using the same handle. + +If you use the easy interface, and you call curl_easy_cleanup(3), all +the possibly open connections held by libcurl are closed and forgotten. + +When you have created a multi handle and are using the multi interface, the +connection pool is instead kept in the multi handle so closing and creating +new easy handles to do transfers do not affect them. Instead all added easy +handles can take advantage of the single shared pool. + +# GLOBAL CONSTANTS + +There are a variety of constants that libcurl uses, mainly through its +internal use of other libraries, which are too complicated for the +library loader to set up. Therefore, a program must call a library +function after the program is loaded and running to finish setting up +the library code. For example, when libcurl is built for SSL +capability via the GNU TLS library, there is an elaborate tree inside +that library that describes the SSL protocol. + +curl_global_init(3) is the function that you must call. This may +allocate resources (e.g. the memory for the GNU TLS tree mentioned above), so +the companion function curl_global_cleanup(3) releases them. + +If libcurl was compiled with support for multiple SSL backends, the function +curl_global_sslset(3) can be called before curl_global_init(3) +to select the active SSL backend. + +The global constant functions are thread-safe since libcurl 7.84.0 if +curl_version_info(3) has the CURL_VERSION_THREADSAFE feature bit set +(most platforms). Read libcurl-thread(3) for thread safety guidelines. + +If the global constant functions are *not thread safe*, then you must +not call them when any other thread in the program is running. It +is not good enough that no other thread is using libcurl at the time, +because these functions internally call similar functions of other +libraries, and those functions are similarly thread-unsafe. You cannot +generally know what these libraries are, or whether other threads are +using them. + +If the global constant functions are *not thread safe*, then the basic rule +for constructing a program that uses libcurl is this: Call +curl_global_init(3), with a *CURL_GLOBAL_ALL* argument, immediately +after the program starts, while it is still only one thread and before it uses +libcurl at all. Call curl_global_cleanup(3) immediately before the +program exits, when the program is again only one thread and after its last +use of libcurl. + +It is not actually required that the functions be called at the beginning +and end of the program -- that is just usually the easiest way to do it. + +You can call both of these multiple times, as long as all calls meet +these requirements and the number of calls to each is the same. + +The global constant situation merits special consideration when the code you +are writing to use libcurl is not the main program, but rather a modular piece +of a program, e.g. another library. As a module, your code does not know about +other parts of the program -- it does not know whether they use libcurl or +not. Its code does not necessarily run at the start and end of the whole +program. + +A module like this must have global constant functions of its own, just like +curl_global_init(3) and curl_global_cleanup(3). The module thus +has control at the beginning and end of the program and has a place to call +the libcurl functions. If multiple modules in the program use libcurl, they +all separately call the libcurl functions, and that is OK because only the +first curl_global_init(3) and the last curl_global_cleanup(3) in a +program change anything. (libcurl uses a reference count in static memory). + +In a C++ module, it is common to deal with the global constant situation by +defining a special class that represents the global constant environment of +the module. A program always has exactly one object of the class, in static +storage. That way, the program automatically calls the constructor of the +object as the program starts up and the destructor as it terminates. As the +author of this libcurl-using module, you can make the constructor call +curl_global_init(3) and the destructor call curl_global_cleanup(3) +and satisfy libcurl's requirements without your user having to think about it. +(Caveat: If you are initializing libcurl from a Windows DLL you should not +initialize it from *DllMain* or a static initializer because Windows holds +the loader lock during that time and it could cause a deadlock.) + +curl_global_init(3) has an argument that tells what particular parts of +the global constant environment to set up. In order to successfully use any +value except *CURL_GLOBAL_ALL* (which says to set up the whole thing), you +must have specific knowledge of internal workings of libcurl and all other +parts of the program of which it is part. + +A special part of the global constant environment is the identity of the +memory allocator. curl_global_init(3) selects the system default memory +allocator, but you can use curl_global_init_mem(3) to supply one of your +own. However, there is no way to use curl_global_init_mem(3) in a +modular program -- all modules in the program that might use libcurl would +have to agree on one allocator. + +There is a failsafe in libcurl that makes it usable in simple situations +without you having to worry about the global constant environment at all: +curl_easy_init(3) sets up the environment itself if it has not been done +yet. The resources it acquires to do so get released by the operating system +automatically when the program exits. + +This failsafe feature exists mainly for backward compatibility because there +was a time when the global functions did not exist. Because it is sufficient +only in the simplest of programs, it is not recommended for any program to +rely on it. diff --git a/src/ext/curl/docs/libcurl/mksymbolsmanpage.pl b/src/ext/curl/docs/libcurl/mksymbolsmanpage.pl new file mode 100755 index 00000000..d7b9a77e --- /dev/null +++ b/src/ext/curl/docs/libcurl/mksymbolsmanpage.pl @@ -0,0 +1,311 @@ +#!/usr/bin/env perl +# *************************************************************************** +# * _ _ ____ _ +# * Project ___| | | | _ \| | +# * / __| | | | |_) | | +# * | (__| |_| | _ <| |___ +# * \___|\___/|_| \_\_____| +# * +# * Copyright (C) Daniel Stenberg, , et al. +# * +# * This software is licensed as described in the file COPYING, which +# * you should have received as part of this distribution.

There are several ways +to detect it being a trailer and not an ordinary header: 1) it comes after the +response-body. 2) it comes after the final header line (CR LF) 3) a Trailer: +header among the regular response-headers mention what header(s) to expect in +the trailer. + +For non-HTTP protocols like FTP, POP3, IMAP and SMTP this function gets called +with the server responses to the commands that libcurl sends. + +A more convenient way to get HTTP headers might be to use +curl_easy_header(3). + +# LIMITATIONS + +libcurl does not unfold HTTP "folded headers" (deprecated since RFC 7230).

By default, only CA root certificates trusted to issue SSL server +authentication certificates are extracted. These are then processed with the +OpenSSL command line tool to produce the final ca-bundle file. + +The default *outputfile* name is **ca-bundle.crt**. By setting it to '-' (a +single dash) you will get the output sent to STDOUT instead of a file. + +The PEM format this scripts uses for output makes the result readily available +for use by just about all OpenSSL or GnuTLS powered applications, such as curl +and others. + +# OPTIONS + +The following options are supported: + +## -b + +backup an existing version of *outputfilename* + +## -d [name] + +specify which Mozilla tree to pull *certdata.txt* from (or a custom +URL). Valid names are: aurora, beta, central, Mozilla, nss, release +(default). They are shortcuts for which source tree to get the certificates +data from. + +## -f + +force rebuild even if *certdata.txt* is current (Added in version 1.17) + +## -i + +print version info about used modules + +## -k + +Allow insecure data transfer. By default (since 1.27) this command will fail +if the HTTPS transfer fails. This overrides that decision (and opens for +man-in-the-middle attacks). + +## -l + +print license info about *certdata.txt* + +## -m + +(Added in 1.26) Include meta data comments in the output. The meta data is +specific information about each certificate that is stored in the original +file as comments and using this option will make those comments get passed on +to the output file. The meta data is not parsed in any way by mk-ca-bundle. + +## -n + +no download of *certdata.txt* (to use existing) + +## -p [purposes]:[levels] + +list of Mozilla trust purposes and levels for certificates to include in +output. Takes the form of a comma separated list of purposes, a colon, and a +comma separated list of levels. The default is to include all certificates +trusted to issue SSL Server certificates (*SERVER_AUTH:TRUSTED_DELEGATOR*). + +Valid purposes are: *ALL*, *DIGITAL_SIGNATURE*, *NON_REPUDIATION*, +*KEY_ENCIPHERMENT*, *DATA_ENCIPHERMENT*, *KEY_AGREEMENT*, *KEY_CERT_SIGN*, +*CRL_SIGN*, *SERVER_AUTH* (default), *CLIENT_AUTH*, *CODE_SIGNING*, +*EMAIL_PROTECTION*, *IPSEC_END_SYSTEM*, *IPSEC_TUNNEL*, *IPSEC_USER*, +*TIME_STAMPING*, *STEP_UP_APPROVED* + +Valid trust levels are: *ALL*, *TRUSTED_DELEGATOR* (default), *NOT_TRUSTED*, +*MUST_VERIFY_TRUST*, *TRUSTED* + +## -q + +be really quiet (no progress output at all) + +## -t + +include plain text listing of certificates + +## -s [algorithms] + +comma separated list of signature algorithms with which to hash/fingerprint +each certificate and output when run in plain text mode. + +Valid algorithms are: +ALL, NONE, MD5 (default), SHA1, SHA256, SHA384, SHA512 + +## -u + +unlink (remove) *certdata.txt* after processing + +## -v + +be verbose and print out processed certificate authorities + +# EXIT STATUS + +Returns 0 on success.

But, to align with the philosophy of Happy + Eyeballs, we don't want to wait _too_ long or users will think + requests are slow when IPv6 lookups don't actually work (but IPv4 ones + do). + + So, now that we have a usable answer (some IPv4 addresses, some IPv6 + addresses, or "no such domain"), we start a timeout for the remaining + pending responses. Even though it is typical that this resolved + request came back quickly, that needn't be the case. It might be that + this completing request didn't get a result from the first DNS server + or even the first round of the whole DNS server pool. So it could + already be quite some time after we issued the DNS queries in the + first place. Without modifying c-ares, we can't know exactly where in + its retry cycle we are. We could guess based on how much time has + gone by, but it doesn't really matter. Happy Eyeballs tells us that, + given usable information in hand, we simply don't want to wait "too + much longer" after we get a result. + + We simply wait an additional amount of time equal to the default + c-ares query timeout. That is enough time for a typical parallel + response to arrive without being "too long".

Libcurl implements an internal +conversion mechanism, but it has been designed for computers that have a +single native character set. OS/400 default native character set varies +depending on the country for which it has been localized. And more, a job +may dynamically alter its "native" character set. + Several characters that do not have fixed code in EBCDIC variants are +used in libcurl strings. As a consequence, using the existing conversion +mechanism would have lead in a localized binary library - not portable across +countries. + For this reason, and because libcurl was originally designed for ASCII based +operating systems, the current OS/400 implementation uses ASCII as internal +character set. This has been accomplished using the QADRT library and +include files, a C and system procedures ASCII wrapper library. See IBM QADRT +description for more information. + This then results in libcurl being an ASCII library: any function string +argument is taken/returned in ASCII and a C/C++ calling program built around +QADRT may use libcurl functions as on any other platform. + QADRT does not define ASCII wrappers for all C/system procedures: the +OS/400 configuration header file and an additional module (os400sys.c) define +some more of them, that are used by libcurl and that QADRT left out. + To support all the different variants of EBCDIC, non-standard wrapper +procedures have been added to libcurl on OS/400: they provide an additional +CCSID (numeric Coded Character Set ID specific to OS/400) parameter for each +string argument. Callback procedures arguments giving access to strings are +NOT converted, so text gathered this way is (probably !) ASCII. + + Another OS/400 problem comes from the fact that the last fixed argument of a +vararg procedure may not be of type char, unsigned char, short or unsigned +short. Enums that are internally implemented by the C compiler as one of these +types are also forbidden. Libcurl uses enums as vararg procedure tagfields... +Happily, there is a pragma forcing enums to type "int". The original libcurl +header files are thus altered during build process to use this pragma, in +order to force libcurl enums of being type int (the pragma disposition in use +before inclusion is restored before resuming the including unit compilation). + + Non-standard EBCDIC wrapper prototypes are defined in an additional header +file: ccsidcurl.h. These should be self-explanatory to an OS/400-aware +designer. CCSID 0 can be used to select the current job's CCSID. + Wrapper procedures with variable arguments are described below: + +_ curl_easy_setopt_ccsid() + Variable arguments are a string pointer and a CCSID (unsigned int) for +options: + CURLOPT_ABSTRACT_UNIX_SOCKET + CURLOPT_ACCEPT_ENCODING + CURLOPT_ALTSVC + CURLOPT_AWS_SIGV4 + CURLOPT_CAINFO + CURLOPT_CAPATH + CURLOPT_COOKIE + CURLOPT_COOKIEFILE + CURLOPT_COOKIEJAR + CURLOPT_COOKIELIST + CURLOPT_CRLFILE + CURLOPT_CUSTOMREQUEST + CURLOPT_DEFAULT_PROTOCOL + CURLOPT_DNS_INTERFACE + CURLOPT_DNS_LOCAL_IP4 + CURLOPT_DNS_LOCAL_IP6 + CURLOPT_DNS_SERVERS + CURLOPT_DOH_URL + CURLOPT_EGDSOCKET + CURLOPT_FTPPORT + CURLOPT_FTP_ACCOUNT + CURLOPT_FTP_ALTERNATIVE_TO_USER + CURLOPT_HAPROXY_CLIENT_IP + CURLOPT_HSTS + CURLOPT_INTERFACE + CURLOPT_ISSUERCERT + CURLOPT_KEYPASSWD + CURLOPT_KRBLEVEL + CURLOPT_LOGIN_OPTIONS + CURLOPT_MAIL_AUTH + CURLOPT_MAIL_FROM + CURLOPT_NETRC_FILE + CURLOPT_NOPROXY + CURLOPT_PASSWORD + CURLOPT_PINNEDPUBLICKEY + CURLOPT_PRE_PROXY + CURLOPT_PROTOCOLS_STR + CURLOPT_PROXY + CURLOPT_PROXYPASSWORD + CURLOPT_PROXYUSERNAME + CURLOPT_PROXYUSERPWD + CURLOPT_PROXY_CAINFO + CURLOPT_PROXY_CAPATH + CURLOPT_PROXY_CRLFILE + CURLOPT_PROXY_ISSUERCERT + CURLOPT_PROXY_KEYPASSWD + CURLOPT_PROXY_PINNEDPUBLICKEY + CURLOPT_PROXY_SERVICE_NAME + CURLOPT_PROXY_SSLCERT + CURLOPT_PROXY_SSLCERTTYPE + CURLOPT_PROXY_SSLKEY + CURLOPT_PROXY_SSLKEYTYPE + CURLOPT_PROXY_SSL_CIPHER_LIST + CURLOPT_PROXY_TLS13_CIPHERS + CURLOPT_PROXY_TLSAUTH_PASSWORD + CURLOPT_PROXY_TLSAUTH_TYPE + CURLOPT_PROXY_TLSAUTH_USERNAME + CURLOPT_RANDOM_FILE + CURLOPT_RANGE + CURLOPT_REDIR_PROTOCOLS_STR + CURLOPT_REFERER + CURLOPT_REQUEST_TARGET + CURLOPT_RTSP_SESSION_ID + CURLOPT_RTSP_STREAM_URI + CURLOPT_RTSP_TRANSPORT + CURLOPT_SASL_AUTHZID + CURLOPT_SERVICE_NAME + CURLOPT_SOCKS5_GSSAPI_SERVICE + CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 + CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 + CURLOPT_SSH_KNOWNHOSTS + CURLOPT_SSH_PRIVATE_KEYFILE + CURLOPT_SSH_PUBLIC_KEYFILE + CURLOPT_SSLCERT + CURLOPT_SSLCERTTYPE + CURLOPT_SSLENGINE + CURLOPT_SSLKEY + CURLOPT_SSLKEYTYPE + CURLOPT_SSL_CIPHER_LIST + CURLOPT_SSL_EC_CURVES + CURLOPT_TLS13_CIPHERS + CURLOPT_TLSAUTH_PASSWORD + CURLOPT_TLSAUTH_TYPE + CURLOPT_TLSAUTH_USERNAME + CURLOPT_UNIX_SOCKET_PATH + CURLOPT_URL + CURLOPT_USERAGENT + CURLOPT_USERNAME + CURLOPT_USERPWD + CURLOPT_XOAUTH2_BEARER + All blob options are also supported. + In all other cases, it ignores the ccsid parameter and behaves as +curl_easy_setopt(). + Note that CURLOPT_ERRORBUFFER is not in the list above, since it gives the +address of an (empty) character buffer, not the address of a string. +CURLOPT_POSTFIELDS stores the address of static binary data (of type void *) +and thus is not converted. If CURLOPT_COPYPOSTFIELDS is issued after +CURLOPT_POSTFIELDSIZE != -1, the data size is adjusted according to the +CCSID conversion result length. + +_ curl_formadd_ccsid() + In the variable argument list, string pointers should be followed by a (long) +CCSID for the following options: + CURLFORM_BUFFER + CURLFORM_CONTENTTYPE + CURLFORM_COPYCONTENTS + CURLFORM_COPYNAME + CURLFORM_FILE + CURLFORM_FILECONTENT + CURLFORM_FILENAME + CURLFORM_PTRNAME + If taken from an argument array, an additional array entry must follow each +entry containing one of the above option. This additional entry holds the CCSID +in its value field, and the option field is meaningless. + It is not possible to have a string pointer and its CCSID across a function +parameter/array boundary. + Please note that CURLFORM_PTRCONTENTS and CURLFORM_BUFFERPTR are considered +unconvertible strings and thus are NOT followed by a CCSID. + +_ curl_easy_getinfo_ccsid() + The following options are followed by a 'char * *' and a CCSID. Unlike +curl_easy_getinfo(), the value returned in the pointer should be released with +curl_free() after use: + CURLINFO_CONTENT_TYPE + CURLINFO_EFFECTIVE_URL + CURLINFO_FTP_ENTRY_PATH + CURLINFO_LOCAL_IP + CURLINFO_PRIMARY_IP + CURLINFO_REDIRECT_URL + CURLINFO_REFERER + CURLINFO_RTSP_SESSION_ID + CURLINFO_SCHEME + Likewise, the following options are followed by a struct curl_slist * * and a +CCSID. + CURLINFO_COOKIELIST + CURLINFO_SSL_ENGINES +Lists returned should be released with curl_slist_free_all() after use. + Option CURLINFO_CERTINFO is followed by a struct curl_certinfo * * and a +CCSID. Returned structures should be freed with curl_certinfo_free_all() +after use. + Other options are processed like in curl_easy_getinfo(). + +_ curl_easy_strerror_ccsid(), curl_multi_strerror_ccsid(), +curl_share_strerror_ccsid() and curl_url_strerror_ccsid() work as their +non-ccsid version and return a string encoded in the additional ccsid +parameter. These strings belong to libcurl and may not be freed by the caller. +A subsequent call to the same procedure in the same thread invalidates the +previous result. + +_ curl_pushheader_bynum_cssid() and curl_pushheader_byname_ccsid() + Although the prototypes are self-explanatory, the returned string pointer +should be released with curl_free() after use, as opposite to the non-ccsid +versions of these procedures. + Please note that HTTP2 is not (yet) implemented on OS/400, thus these +functions will always return NULL. + +_ curl_easy_option_by_name_ccsid() returns a pointer to an untranslated option +metadata structure. As each curl_easyoption structure holds the option name in +ASCII, the curl_easy_option_get_name_ccsid() function allows getting it in any +supported ccsid. However the caller should release the returned pointer with +curl_free() after use. + +_ curl_easy_header_ccsid() works as its non-CCSID counterpart but requires an +additional ccsid parameter specifying the name parameter encoding. The output +hout parameter is kept in libcurl's encoding and should not be altered. + +_ curl_from_ccsid() and curl_to_ccsid() are string encoding conversion +functions between ASCII (latin1) and the given CCSID. The first parameter is +the source string, the second is the CCSID and the returned value is a pointer +to the dynamically allocated string.

If + another EBCDIC CCSID is required, it must be set via a locale through a call + to setlocale_a (QADRT's setlocale() ASCII wrapper) with category LC_ALL or + LC_CTYPE, or by setting environment variable QADRT_ENV_LOCALE to the locale + object path before executing the program. +_ Do not use original source include files unless you know what you are doing. + Use the installed members instead (in /QSYS.LIB/CURL.LIB/H.FILE and + /curl/include/curl). + + + +ILE/RPG support: + + Since most of the ILE OS/400 programmers use ILE/RPG exclusively, a +definition /INCLUDE member is provided for this language. To include all +libcurl definitions in an ILE/RPG module, line + + h bnddir('CURL/CURL') + +must figure in the program header, and line + + d/include curl/h,curl.inc + +in the global data section of the module's source code. + + No vararg procedure support exists in ILE/RPG: for this reason, the following +considerations apply: +_ Procedures curl_easy_setopt_long(), curl_easy_setopt_object(), + curl_easy_setopt_function(), curl_easy_setopt_offset() and + curl_easy_setopt_blob() are all alias prototypes to curl_easy_setopt(), but + with different parameter lists. +_ Procedures curl_easy_getinfo_string(), curl_easy_getinfo_long(), + curl_easy_getinfo_double(), curl_easy_getinfo_slist(), + curl_easy_getinfo_ptr(), curl_easy_getinfo_socket() and + curl_easy_getinfo_off_t() are all alias prototypes to curl_easy_getinfo(), + but with different parameter lists. +_ Procedures curl_multi_setopt_long(), curl_multi_setopt_object(), + curl_multi_setopt_function() and curl_multi_setopt_offset() are all alias + prototypes to curl_multi_setopt(), but with different parameter lists. +_ Procedures curl_share_setopt_int(), curl_share_setopt_ptr() and + curl_share_setopt_proc() are all alias prototypes to curl_share_setopt, + but with different parameter lists. +_ Procedure curl_easy_setopt_blob_ccsid() is an alias of + curl_easy_setopt_ccsid() supporting blob encoding conversion. +_ The prototype of procedure curl_formadd() allows specifying a pointer option + and the CURLFORM_END option. This makes possible to use an option array + without any additional definition. If some specific incompatible argument + list is used in the ILE/RPG program, the latter must define a specialised + alias. The same applies to curl_formadd_ccsid() too. +_ Since V7R4M0, procedure overloading is used to emulate limited "vararg-like" + definitions of curl_easy_setopt(), curl_multi_setopt(), curl_share_setopt() + and curl_easy_getinfo(). Blob and CCSID alternatives are NOT included in + overloading. + + Since RPG cannot cast a long to a pointer, procedure curl_form_long_value() +is provided for that purpose: this allows storing a long value in the +curl_forms array. Please note the form API is deprecated and the MIME API +should be used instead. + + +CLI tool: + + The build system provides it as a bound program, an IFS link to it and a +simple CL command. The latter however is not able to provide a different +parameter for each option since there are too many of those; instead, +parameters are entered in a single field subject to quoting and escaping, in +the same form as expected by the standard CLI program. + Care must be taken about the program output encoding: by default, it is sent +to the standard output and is thus subject to transcoding. It is therefore +recommended to use option "--output" to redirect output to a specific IFS file. +Similar problems may occur about the standard input encoding. diff --git a/src/ext/curl/packages/OS400/ccsidcurl.c b/src/ext/curl/packages/OS400/ccsidcurl.c new file mode 100644 index 00000000..596c1f1e --- /dev/null +++ b/src/ext/curl/packages/OS400/ccsidcurl.c @@ -0,0 +1,1527 @@ +/*************************************************************************** + * _ _ ____ _ + * Project ___| | | | _ \| | + * / __| | | | |_) | | + * | (__| |_| | _ <| |___ + * \___|\___/|_| \_\_____| + * + * Copyright (C) Daniel Stenberg, , et al. + * + * This software is licensed as described in the file COPYING, which + * you should have received as part of this distribution.

A concealed logical name of +OLD_GNU: can be set up to reference the real GNV directory tree. + +Then a local copy of the GNU/GNV$GNU logical names can be set up as a search +list such as NEW_GNU:,OLD_GNU: + +The directory NEW_GNU:[usr] should be created. The make install phase should +create all the other directories. + +The make install process may abort if curl is already because it can not +uninstall the older version of curl because it does not have permission. + +The file stage_curl_install.com is used set up a new_gnu: directory tree +for testing. The PCSI kitting procedure uses these files as input. + +These files do not create the directories in the VMS_ROOT and LCL_ROOT +directory trees. You can create them with commands similar to: + + $ create/dir lcl_root:[curl]/prot=w:re + $ copy src_root:[curl...]*.dir - + lcl_root:[curl...]/prot=(o:rwed,w:re) + $ create/dir vms_root:[curl]/prot=w:re + $ copy src_root:[curl...]*.dir - + vms_root:[curl...]/prot=(o:rwed,w:re) + +One of the ways with to protect the source from being modified is to have +the directories under src_root: owned by a user or resource where the build +username only has read access to it. + + +Note to builders: + +GNV currently has a bug where configure scripts take a long time to run. +Some of the configure steps take a while to complete, and on a 600 Mhz +DS10 with IDE disks, taking an hour to run the CURL configure is normal. + +The following messages can be ignored and may get fixed in a future version +of GNV. The GNV$*.OPT files are used to find the libraries as many have +different names on VMS than on Unix. The Bash environment variable +GNV_CC_QUALIFIERS can override all other settings for the C Compiler. + +? cc: No support for switch -warnprotos +? cc: Unrecognized file toomanyargs +? cc: Warning: library "ssl" not found +? cc: Warning: library "crypto" not found +? cc: Warning: library "gssapi" not found +? cc: Warning: library "z" not found +u unimplemented switch - ignored + + +With these search lists set up and the properly, curl can be built by +setting your default to PRJ_ROOT:[curl.packages.vms] and then issuing +either the command: + + $ @pcsi_product_gnv_curl.com + +or + + $ @build_gnv_curl.com. + +The GNV configure procedure takes considerably longer than the DCL build +procedure takes. It is of use for testing the GNV build environment, and +may not have been kept up to date. + +The pcsi_product_gnv_curl.com needs the following logical names which +are described in the section below: + + gnv_pcsi_producer + gnv_pcsi_producer_full_name + stage_root + vms_root1 (Optional if vms_root is on a NFS volume) + src_root1 (Optional if src_root is on a NFS volume) + +The pcsi_product_gnv_curl.com is described in more detail below. It does +the following steps. The build steps are only done if they are needed to +allow using either DCL or GNV based building procedures. + + $ @build_vms list + + $ @gnv_link_curl.com + + $ @build_gnv_curl_release_notes.com + + $ @backup_gnv_curl_src.com + + $ @build_gnv_curl_pcsi_desc.com + + $ @build_gnv_curl_pcsi_text.com + + $ @stage_curl_install remove + $ @stage_curl_install + + Then builds the kit. + +The build_gnv_curl.com command procedure does the following: + + $ @setup_gnv_curl_build.com + + $ bash gnv_curl_configure.sh + + $ @clean_gnv_curl.com + + $ bash make_gnv_curl_install.sh + + $ @gnv_link_curl.com + + $ @stage_curl_install.com + + $ purge new_gnu:[*...]/log + +To clean up after a GNV based build to start over, the following commands are +used: + + $ bash + bash$ cd ../.. + bash$ make clean + bash$ exit + +Then run the @clean_gnv_curl.com.

If the symbols are longer than 32 characters, +then they will need to have the original be exact case CRC shortened and +an alias in upper case with CRC shortened, in addition to having an exact +case truncated alias and an uppercase truncated alias. + +The *.EXE files are not moved to the new_gnu: directory. + +After you are satisfied with the results of your build, you can move the +files from new_gnu: to old_gnu: at your convenience. + +Building a PCSI kit for an architecture takes the following steps after +making sure that you have a working build environment. + +Note that it requires manually creating two logical names as described +below. It is intentional that they be manually set. This is for +branding the PCSI kit based on who is making the kit. + + 1. Make sure that you have a staging directory that can be referenced + by the path STAGE_ROOT:[KIT] + + 2. Edit the file curl_release_note_start.txt or other text files to + reflect any changes. + + 3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making + the distribution. For making updates to an existing open source + kit you may need to keep the producer the same. + + 4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full + name or full name of your company. + + 5. If you are producing an update kit, then update the file + vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro. + This file is currently only used in building the PCSI kit. + + 6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added + to the kit. These files should all be ODS-2 legal filenames and + directories. + + A limitation of the PCSI kitting procedure is that when selecting files, + it tends to ignore the directory structure and assumes that all files + with the same name are the same file, so every file placed in the kit + must have a unique name. Then a procedure needs to be added to the kit + to create an alias link on install and remove the link on remove. + + Since at this time curl does not need this alias procedure, the steps + to automatically build it are not included here. + + While newer versions of PCSI can support ODS-5 filenames, not all versions + of PCSI on systems that have ODS-5 filenames do. So as a post install + step, the PCSI kit built by these steps does a rename to the correct + case as a post install step. + + 7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you + have changed the version of ZLIB that curl is built against. + + 8. Prepare to backup the files for building the kit. + + Note that if src_root: or vms_root: are NFS mounted disks, the + step of backing up the source files will probably hang or fail. + + You need to copy the source files to VMS mounted disks and create + logical names SRC_ROOT1 and VMS_ROOT1 to work around this to + reference local disks. Make sure src_root1:[000000] and + vms_root1:[000000] exist and can be written to. + + The command procedure compare_curl_source can be used to check + those directories and keep them up to date. + + @compare_curl_source.com SRCBCK UPDATE + + This compares the reference project source with the backup + staging directory for it and updates with any changes. + + @compare_curl_source.com VMSBCK UPDATE + + This compares the VMS specific source with the backup + staging directory for it and updates with any changes. + + Leave off "UPDATE" to just check without doing any changes. + + If you are not using NFS mounted disks and do not want to have a + separate directory for staging the sources for backup make sure + that src_root1: and vms_root1: do not exist. + + 9. Build the PCSI kit with @pcsi_product_gnv_curl.com + + The following message is normal: + %PCSI-I-CANNOTVAL, cannot validate + EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1 + -PCSI-I-NOTSIGNED, product kit is not signed and therefore has + no manifest file + + This will result in an uncompressed kit for the target platform. + On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with + the "COMPRESSED" parameter to build both a compressed and uncompressed + kits. + +Good Luck. diff --git a/src/ext/curl/packages/vms/curl_release_note_start.txt b/src/ext/curl/packages/vms/curl_release_note_start.txt new file mode 100644 index 00000000..62b28363 --- /dev/null +++ b/src/ext/curl/packages/vms/curl_release_note_start.txt @@ -0,0 +1,77 @@ +From file: CURL_RELEASE_NOTE_START.TXT + +Note: These kits are produced by a hobbyist and are providing any support +or any commitment to supply bug fixes or future releases.

Use the "REALCLEAN" option for +BUILD_VMS.COM and the "REALCLEAN" option for clean_gnv_curl.com. + +The (brute-force) DCL based builder is [.packages.vms]build_vms.com. +Comments in this procedure describe various optional parameters which +enable or disable optional program features, or which control the build +in other ways. Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...) +should be produced in an architecture-specific subdirectory under this +directory ([.ALPHA], [.IA64], [.VAX]). + +The file curl_gnv_build_steps.txt contains information on building using +the GNV tool kit, building a shared libcurl, and producing a PCSI kit for +distribution.

If you have built a curl with ZLIB and HPSSL support as well as if +LDAP and Kerberos installed, you can use the GNV_LINK_CURL.COM file. + +The GNV_LINK_CURL.COM contains information on how to link and run with a newer +version of HP SSL than what may be install on an Alpha or IA64 based system. + +To build the PCSI kit, follow the instructions in the file +curl_gnv_build_steps.txt. + +Other Notes: + +This release fixes known bugs #22, and #57 in the [curl.docs]known_bugs. +file. + +The libcurl formdata.c module and Curl tools post form now have some +understanding of VMS file types. Files will be posted in STREAM_LF format. + +The Curl tool now has some understanding of VMS file types and will upload the +files in STREAM_LF format. + +When CURL is uploading a VARIABLE format VMS file, it is less efficient as in +order to get the file size, it will first read the entire file once, and then +read the file again for the actual upload. + +The Curl tool will now always download files into STREAM_LF format. Even if a +file by that name with a different format already exists. This is needed to +allow interrupted downloads to be continued. + + +The libcurl file module still does not understand VMS file types and requires +the input files to be in STREAM_LF to work property. + +The test suites are not supported as of 7.11.0. + +The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg. +This is not done automatically, since the .MSG file is a hand edit +of the relevant stuff from the curl.h file.

See\n" +" libcurl(3) for details.\n" +"\n" +"URL\n" +" The URL syntax is protocol-dependent. You find a detailed description\n" +" in RFC 3986.\n" +"\n" +" If you provide a URL without a leading protocol:// scheme, curl guesses\n" +, stdout); + fputs( +" what protocol you want.
