NEWS for rsync 3.1.2 (21 Dec 2015)
Protocol: 31 (unchanged)
Changes since 3.1.1:
SECURITY FIXES:
- Make sure that all transferred files use only path names from inside the
transfer. This makes it impossible for a malicious sender to try to make
the receiver use an unsafe destination path for a transferred file, such
as a just-sent symlink.
BUG FIXES:
- Change the checksum seed order in the per-block checksums. This prevents
someone from trying to create checksum blocks that match in sum but not
content.
- Fixed a with the per-dir filter files (using -FF) that could trigger an
assert failure.
- Only skip set_modtime() on a transferred file if the time is exactly
right.
- Don't create an empty backup dir for a transferred file that doesn't
exist yet.
- Fixed a bug where --link-dest and --xattrs could cause rsync to exit if
a filename had a matching dir of the same name in the alt-dest area.
- Allow more than 32 group IDs per user in the daemon's gid=LIST config.
- Fix the logging of %b & %c via --log-file (daemon logging was already
correct, as was --out-format='%b/%c').
- Fix erroneous acceptance of --info=5 & --debug=5 (an empty flag name is
not valid).
ENHANCEMENTS:
- Added "(DRY RUN)" info to the --debug=exit output line.
- Use usleep() for our msleep() function if it is available.
- Added a few extra long-option names to rrsync script, which will make
BackupPC happier.
- Made configure choose to use linux xattrs on netbsd (rather than not
supporting xattrs).
- Added -wo (write-only) option to rrsync support script.
- Misc. manpage tweaks.
DEVELOPER RELATED:
- Fixed a bug with the Makefile's use of INSTALL_STRIP.
- Improve a test in the suite that could get an erroneous timestamp error.
- Tweaks for newer versions of git in the packaging tools.
- Improved the m4 generation rules and some autoconf idioms.
NEWS for rsync 3.1.1 (22 Jun 2014)
Protocol: 31 (unchanged)
Changes since 3.1.0:
BUG FIXES:
- If the receiver gets bogus filenames from the sender (an unexpected
leading slash or a ".." infix dir), exit with an error. This prevents a
malicious sender from trying to inject filenames that would affect an
area outside the destination directories.
- Fixed a failure to remove the partial-transfer temp file when interrupted
(and rsync is not saving the partial files).
- Changed the chown/group/xattr-set order to avoid losing some security-
related xattr info (that would get cleared by a chown).
- Fixed a bug in the xattr-finding code that could make a non-root-run
receiver not able to find some xattr numbers.
- Fixed a bug in the early daemon protocol where a timeout failed to be
honored (e.g. if the remote side fails to send us the initial protocol
greeting).
- Fixed unintended inclusion of commas in file numbers in the daemon log.
- We once again send the 'f' sub-flag (of -e) to the server side so it
knows that we can handle incremental-recursion directory errors properly
in older protocols.
- Fixed an issue with too-aggressive keep-alive messages causing a problem
for older rsync versions early in the transfer.
- Fixed an incorrect message about backup-directory-creation when using
--dry-run and the backup dir is not an absolute path.
- Fixed a bug where a failed deletion and/or a failed sender-side removal
would not affect the exit code.
- Fixed a bug that caused a failure when combining --delete-missing-args
with --xattrs and/or --acls.
- Fixed a strange dir_depth assertion error that was caused by empty-dir
removals and/or duplicate files in the transfer.
- Fixed a problem with --info=progress2's output stats where rsync would
only update the stats at the end of each file's transfer. It now uses
the data that is flowing for the current file, making the stats more
accurate and less jumpy.
- Fixed an itemize bug that affected the combo of --link-dest, -X, and -n.
- Fixed a problem with delete messages not appearing in the log file when
the user didn't use --verbose.
- Improve chunked xattr reading for OS X.
- Removed an attempted hard-link xattr optimization that was causing a
transfer failure. This removal is flagged in the compatibility code, so
if a better fix can be discovered, we have a way to flip it on again.
- Fixed a bug when the receiver is not configured to be able to hard link
symlimks/devices/special-file items but the sender sent some of these
items flagged as hard-linked.
- We now generate a better error if the buffer overflows in do_mknod().
- Fixed a problem reading more than 16 ACLs on some OSes.
- Fixed the reading of the secrets file to avoid an infinite wait when
the username is missing.
- Fixed a parsing problem in the --usermap/--groupmap options when using
MIN-MAX numbers.
- Switched Cygwin back to using socketpair "pipes" to try to speed it up.
- Added knowledge of a few new options to rrsync.
ENHANCEMENTS:
- Tweaked the temp-file naming when --temp-dir=DIR is used: the temp-file
names will not get a '.' prepended.
- Added support for a new-compression idiom that does not compress all the
matching data in a transfer. This can help rsync to use less cpu when a
transfer has a lot of matching data, and also makes rsync compatible with
a non-bundled zlib. See the --new-compress and --old-compress options in
the manpage.
- Added the support/rsync-no-vanished wrapper script.
- Made configure more prominently mention when we failed to find yodl (in
case the user wants to be able to generate manpages from *.yo files).
- Have manpage mention how a daemon's max-verbosity setting affects info
and debug options. Also added more clarification on backslash removals
for excludes that contain wildcards.
- Have configure check if for the attr lib (for getxattr) for those systems
that need to link against it explicitly.
- Change the early dir-creation logic to only use that idiom in an
inc-recursive copy that is preserving directory times. e.g. using
--omit-dir-times will avoid these early directories being created.
- Fix a bug in cmp_time() that would return a wrong result if the 2 times
differed by an amount greater than what a time_t can hold.
DEVELOPER RELATED:
- We now include an example systemd file (in packaging/systemd).
- Tweaked configure to make sure that any intended use of the included popt
and/or zlib code is put early in the CFLAGS.
NEWS for rsync 3.1.0 (28 Sep 2013)
Protocol: 31 (changed)
Changes since 3.0.9:
OUTPUT CHANGES:
- Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
--human-readable option for a way to turn it off. See also the daemon's
"log format" parameter and related command-line options (including
--out-format) for a modifier that can be used to request digit-grouping
or human-readable output in log escapes. (Note that log output is
unchanged by default.)
- The --list-only option is now affected by the --human-readable setting.
It will display digit groupings by default, and unit suffixes if higher
levels of readability are requested. Also, the column width for the size
output has increased from 11 to 14 characters when human readability is
enabled. Use --no-h to get the old-style output and column size.
- The output of the --progress option has changed: the string "xfer" was
shortened to "xfr", and the string "to-check" was shortened to "to-chk",
both designed to make room for the (by default) wider display of file
size numbers without making the total line-length longer. Also, when
incremental recursion is enabled, the string "ir-chk" will be used
instead of "to-chk" up until the incremental-recursion scan is done,
letting you know that the value to check and the total value will still
be increasing as new files are found.
- Enhanced the --stats output: 1) to mention how many files were created
(protocol >= 28), 2) to mention how many files were deleted (a new line
for protocol 31, but only output when --delete is in effect), and 3) to
follow the file-count, created-count, and deleted-count with a subcount
list that shows the counts by type. The wording of the transferred count
has also changed so that it is clearer that it is only a count of regular
files.
BUG FIXES:
- Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
full output buffer.
- Fixed some rare bugs in --iconv processing that might cause a multibyte
character to get translated incorrectly.
- Fixed a bogus "vanished file" error if some files were specified with
"./" prefixes and others were not.
- Fixed a bug in --sparse where an extra gap could get inserted after a
partial write.
- Changed the way --progress overwrites its prior output in order to make
it nearly impossible for the progress to get overwritten by an error.
- Improved the propagation of abnormal-exit error messages. This should
help the client side to receive errors from the server when it is exiting
abnormally, and should also avoid dying with an "connection unexpectedly
closed" exit when the closed connection is really expected.
- The sender now checks each file it plans to remove to ensure that it
hasn't changed from the first stat's info. This helps to avoid losing
file data when the user is not using the option in a safe manner.
- Fixed a data-duplication bug in the compress option that made compression
less efficient. This improves protocol 31 onward, while behaving in a
compatible (buggy) manner with older rsync protocols.
- When creating a temp-file, rsync is now a bit smarter about it dot-char
choices, which can fix a problem on OS X with names that start with "..".
- Rsync now sets a cleanup flag for --inplace and --append transfers that
will flush the write buffer if the transfer aborts. This ensures that
more received data gets written out to the disk on an aborted transfer
(which is quite helpful on a slow, flaky connection).
- The reads that map_ptr() now does are aligned on 1K boundaries. This
helps some filesystems and/or files that don't like unaligned reads.
- Fix an issue in the msleep() function if time jumps backwards.
- Fix daemon-server module-name splitting bug where an arg would get split
even if --protect-args was used.
ENHANCEMENTS:
- Added the --remote-option=OPT (-M OPT) command-line option that is useful
for things like sending a remote --log-file=FILE or --fake-super option.
- Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
control over what is output. Added an extra type of --progress output
using --info=progress2.
- The --msgs2stderr option can help with debugging rsync by allowing the
debug messages to get output to stderr rather than travel via the socket
protocol.
- Added the --delete-missing-args and --ignore-missing-args options to
either delete or ignore user-specified files on the receiver that are
missing on the sender (normally the absence of user-specified files
generates an error).
- Added a "T" (terabyte) category to the --human-readable size suffixes.
- Added the --usermap/--groupmap/--chown options for manipulating file
ownership during the copy.
- Added the "%C" escape to the log-output handling, which will output the
MD5 checksum of any transferred file, or all files if --checksum was
specified (when protocol 30 or above is in effect).
- Added the "reverse lookup" parameter to the rsync daemon config file to
allow reverse-DNS lookups to be disabled.
- Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
be disabled via "forward lookup" parameter (defaults to enabled).
- Added a way for more than one group to be specified in the daemon's
config file, including a way to specify that you want all of the
specified user's groups without having to name them. Also changed the
daemon to complain about an inability to set explicitly-specified uid/gid
values, even when not run by a super-user.
- The daemon now tries to send the user the error messages from the
pre-xfer exec script when it fails.
- Improved the use of alt-dest options into an existing hierarchy of files:
If a match is found in an alt-dir, it takes precedence over an existing
file. (We'll need to wait for a future version before attribute-changes
on otherwise unchanged files are safe when using an existing hierarchy.)
- Added per-user authorization options and group-authorization support to
the daemon's "auth users" parameter.
- Added a way to reference environment variables in a daemon's config file
(using %VAR% references).
- When replacing a non-dir with a symlink/hard-link/device/special-file,
the update should now be done in an atomic manner.
- Avoid re-sending xattr info for hard-linked files w/the same xattrs
(protocol 31).
- The backup code was improved to use better logic maintaining the backup
directory hierarchy. Also, when a file is being backed up, rsync tries
to hard-link it into place so that the upcoming replacement of the
destination file will be atomic (for the normal, non-inplace logic).
- Added the ability to synchronize nano-second modified times.
- Added a few more default suffixes for the "dont compress" settings.
- Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
the default for the --protect-args command-line option to be overridden.
- Added the --preallocate command-line option.
- Allow --password-file=- to read the password from stdin (filename "-").
- Rsync now comes packaged with an rsync-ssl helper script that can be
used to contact a remote rsync daemon using a piped-stunnel command.
It also includes an stunnel config file to run the server side to
support ssl daemon connections. See the packaging/lsb/rsync.spec
file for one way to package the resulting files. (Suggestions for
how to make this even easier to install & use are welcomed.)
- Improved the speed of some --inplace updates when there are lots of
identical checksum blocks that end up being unusable.
- Added the --outbuf=N|L|B option for choosing the output buffering.
- Repeating the --fuzzy option now causes the code to look for fuzzy
matches inside alt-dest directories too.
- The --chmod option now supports numeric modes, e.g. --chmod=644,D755
- Added some Solaris xattr code.
- Made an rsync daemon (the listening process) exit with a 0 status when
it was signaled to die. This helps launchd.
- Improved the RSYNC_* environment variables for the pre-xfer exec script:
when a daemon is sent multiple request args, they are now joined into a
single return value (separated by spaces) so that the RSYNC_REQUEST
environment variable is accurate for any "pre-xfer exec". The values in
RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
request dirs/files), so that all the requested values are also listed
(separately) in RSYNC_ARG# variables.
EXTRAS:
- Added an "instant-rsyncd" script to the support directory, which makes
it easy to configure a simple rsync daemon in the current directory.
- Added the "mapfrom" and "mapto" scripts to the support directory, which
makes it easier to do user/group mapping in a local transfer based on
passwd/group files from another machine.
- There's a new, improved version of the lsh script in the support dir:
it's written in perl and supports -u without resorting to using sudo
(when run as root). The old shell version is now named lsh.sh.
- There is a helper script named rsync-slash-strip in the support directory
for anyone that wants to change the way rsync handles args with trailing
slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
arg/).
INTERNAL:
- The I/O code was rewritten to be simpler and do bigger buffered reads
over the socket. The I/O between the receiver and the generator was
changed to be standard multiplexed-I/O (like that over the socket).
- The sender tries to use any dead time while the generator is looking for
files to transfer in order to do sender-side directory scanning in a more
parallel manner.
- A daemon can now inform a client about a daemon-configured timeout value
so that the client can assist in the keep-alive activity (protocol 31).
- The filter code received some refactoring to make it more extendible, to
read better, and do better sanity checking.
- Really big numbers are now output using our own big-num routine rather
than casting them to a double and using a %.0f conversion.
- The pool_alloc library has received some minor improvements in alignment
handling.
- Added init_stat_x() function to avoid duplication of acl/xattr init code.
- The included zlib was upgraded from 1.2.3 to 1.2.8.
- Rsync can now be compiled to use an unmodified zlib library instead of
the tweaked one that is included with rsync. This will eventually
become the default, at which point we'll start the countdown to removing
the included zlib. Until then, feel free to configure using:
./configure --with-included-zlib=no
DEVELOPER RELATED:
- Added more conditional debug output.
- Fixed some build issues for android and minix.
NEWS for rsync 3.0.9 (23 Sep 2011)
Protocol: 30 (unchanged)
Changes since 3.0.8:
BUG FIXES:
- Fix a crash bug in checksum scanning when --inplace is used.
- Fix a hang if a hard-linked file cannot be opened by the sender (e.g.
if it has no read permission).
- Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
- Fix a memory leak in the xattr code.
- Fixed a bug with --delete-excluded when a filter merge file has a rule
that specifies a receiver-only side restriction.
- Fix a bug with the modifying of unwritable directories.
- Fix --fake-super's interaction with --link-dest same-file comparisons.
- Fix the updating of the curr_dir buffer to avoid a duplicate slash.
- Fix the directory permissions on an implied dot-dir when using --relative
(e.g. /outside/path/././send/path).
- Fixed some too-long sleeping instances when using --bwlimit.
- Fixed when symlink ownership difference-checking gets compiled into
unchanged_attrs().
- Improved the socket-error reporting when multiple protocols fail.
- Fixed a case where a socket error could reference just-freed memory.
- Failing to use a password file that was specified on the command-line is
now a fatal error.
- Fix the non-root updating of directories that don't have the read and/or
execute permission.
- Make daemon-excluded file errors more error-like.
- Fix a compilation issue on older C compilers (due to a misplaced var
declaration).
- Make configure avoid finding socketpair on cygwin.
- Avoid trying to reference SO_BROADCAST if the OS doesn't support it.
- Fix some issues with the post-processing of the man pages.
- Fixed the user home-dir handling in the support/lsh script.
- Some minor manpage improvements.
NEWS for rsync 3.0.8 (26 Mar 2011)
Protocol: 30 (unchanged)
Changes since 3.0.7:
BUG FIXES:
- Fixed two buffer-overflow issues: one where a directory path that is
exactly MAXPATHLEN was not handled correctly, and one handling a
--backup-dir that is extra extra large.
- Fixed a data-corruption issue when preserving hard-links without
preserving file ownership, and doing deletions either before or during
the transfer (CVE-2011-1097). This fixes some assert errors in the
hard-linking code, and some potential failed checksums (via -c) that
should have matched.
- Fixed a potential crash when an rsync daemon has a filter/exclude list
and the transfer is using ACLs or xattrs.
- Fixed a hang if a really large file is being processed by an rsync that
can't handle 64-bit numbers. Rsync will now complain about the file
being too big and skip it.
- For devices and special files, we now avoid gathering useless ACL and/or
xattr information for files that aren't being copied. (The un-copied
files are still put into the file list, but there's no need to gather
data that is not going to be used.) This ensures that if the user uses
--no-D, that rsync can't possibly complain about being unable to gather
extended information from special files that are in the file list (but
not in the transfer).
- Properly handle requesting remote filenames that start with a dash. This
avoids a potential error where a filename could be interpreted as a
(usually invalid) option.
- Fixed a bug in the comparing of upper-case letters in file suffixes for
--skip-compress.
- If an rsync daemon has a module configured without a path setting, rsync
will now disallow access to that module.
- If the destination arg is an empty string, it will be treated as a
reference to the current directory (as 2.x used to do).
- If rsync was compiled with a newer time-setting function (such as
lutimes), rsync will fall-back to an older function (such as utimes) on a
system where the newer function is not around. This helps to make the
rsync binary more portable in mixed-OS-release situations.
- Fixed a batch-file writing bug that would not write out the full set of
compatibility flags that the transfer was using. This fixes a potential
protocol problem for a batch file that contains a sender-side I/O error:
it would have been sent in a way that the batch-reader wasn't expecting.
- Some improvements to the hard-linking code to ensure that device-number
hashing is working right, and to supply more information if the hard-link
code fails.
- The --inplace code was improved to not search for an impossible checksum
position. The quadruple-verbose chunk[N] message will now mention when
an inplace chunk was handled by a seek rather than a read+write.
- Improved ACL mask handling, e.g. for Solaris.
- Fixed a bug that prevented --numeric-ids from disabling the translation
of user/group IDs for ACLs.
- Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
option (e.g. --link-dest) could output an error trying to itemize the
changes against the alt-dest directory's xattr/ACL info but was instead
trying to access the not-yet-existing new destination directory.
- Improved xattr system-error messages to mention the full path to the
file.
- The --link-dest checking for identical symlinks now avoids considering
attribute differences that cannot be changed on the receiver.
- Avoid trying to read/write xattrs on certain file types for certain OSes.
Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
NO_SPECIAL_XATTRS defines in config.h.
- Improved the unsafe-symlink errors messages.
- Fixed a bug setting xattrs on new files that aren't user writable.
- Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
- Fixed a bug with --fake-super when copying files and dirs that aren't
user writable.
- Fixed a bug where a sparse file could have its last sparse block turned
into a real block when rsync sets the file size (requires ftruncate).
- If a temp-file name is too long, rsync now avoids truncating the name in
the middle of adjacent high-bit characters. This prevents a potential
filename error if the filesystem doesn't allow a name to contain an
invalid multi-byte sequence.
- If a muli-protocol socket connection fails (i.e., when contacting a
daemon), we now report all the failures, not just the last one. This
avoids losing a relevant error (e.g. an IPv4 connection-refused error)
that happened before the final error (e.g. an IPv6 protocol-not-supported
error).
- Generate a transfer error if we try to call chown with a -1 for a uid or
a gid (which is not settable).
- Fixed the working of --force when used with --one-file-system.
- Fix the popt arg parsing so that an option that doesn't take an arg will
reject an attempt to supply one (can configure --with-included-popt if
your system's popt library doesn't yet have this fix).
- A couple minor option tweaks to the support/rrsync script, and also some
regex changes that make vim highlighting happier.
- Fixed some issues in the support/mnt-excl script.
- Various manpage improvements.
ENHANCEMENTS:
- Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
DEVELOPER RELATED:
- Use lchmod() whenever it is available (not just on symlinks).
- A couple fixes to the socketpair_tcp() routine.
- Updated the helper scripts in the packaging subdirectory.
- Renamed configure.in to configure.ac.
- Fixed configure's checking for iconv routines for newer OS X versions.
- Fixed the testsuite/xattrs.test script on OS X.
NEWS for rsync 3.0.7 (31 Dec 2009)
Protocol: 30 (unchanged)
Changes since 3.0.6:
BUG FIXES:
- Fixed a bogus free when using --xattrs with --backup.
- Avoid an error when --dry-run was trying to stat a prior hard-link file
that hasn't really been created.
- Fixed a problem with --compress (-z) where the receiving side could
return the error "inflate (token) returned -5".
- Fixed a bug where --delete-during could delete in a directory before it
noticed that the sending side sent an I/O error for that directory (both
sides of the transfer must be at least 3.0.7).
- Improved --skip-compress's error handling of bad character-sets and got
rid of a lingering debug fprintf().
- Fixed the daemon's conveyance of io_error value from the sender.
- An rsync daemon use seteuid() (when available) if it used setuid().
- Get the permissions right on a --fake-super transferred directory that
needs more owner permissions to emulate root behavior.
- An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
its modifier when sending the filter rules to the remote rsync.
- Improved the "--delete does not work without -r or -d" message.
- Improved rsync's handling of --timeout to avoid a weird timeout case
where the sender could timeout even though it has recently written data
to the socket (but hasn't read data recently, due to the writing).
- Some misc manpage improvements.
- Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
- Make sure that a timeout specified in the daemon's config is used as a
maximum timeout value when the user also specifies a timeout.
- Improved the error-exit reporting when rsync gets an error trying to
cleanup after an error: the initial error is reported.
- Improved configure's detection of IPv6 for solaris and cygwin.
- The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
- Made our (only used if missing) getaddrinfo() routine use inet_pton()
(which we also provide) instead of inet_aton().
- The exit-related debug messages now mention the program's role so it is
clear who output what message.
DEVELOPER RELATED:
- Got rid of type-punned compiler warnings output by newer gcc versions.
- The Makefile now ensures that proto.h will be rebuilt if config.h changes.
- The testsuite no longer uses "id -u", so it works better on solaris.
NEWS for rsync 3.0.6 (8 May 2009)
Protocol: 30 (unchanged)
Changes since 3.0.5:
BUG FIXES:
- Fixed a --read-batch hang when rsync is reading a batch file that was
created from an incremental-recursion transfer.
- Fixed the daemon's socket code to handle the simultaneous arrival of
multiple connections.
- Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
have consecutive slashes in the value.
- Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
- The sender now skips a (bogus) symlink that has a 0-length value, which
avoids a transfer error in the receiver.
- Fixed a case where the sender could die with a tag-0 error if there was
an I/O during the sending of the file list.
- Fixed the rrsync script to avoid a server-side problem when -e is at the
start of the short options.
- Fixed a problem where a vanished directory could turn into an exit code
23 instead of the proper exit code 24.
- Fixed the --iconv conversion of symlinks when doing a local copy.
- Fixed a problem where --one-file-system was not stopping deletions on the
receiving side when a mount-point directory did not match a directory in
the transfer.
- Fixed the dropping of an ACL mask when no named ACL values were present.
- Fixed an ACL/xattr corruption issue where the --backup option could cause
rsync to associate the wrong ACL/xattr information with received files.
- Fixed the use of --xattrs with --only-write-batch.
- Fixed the use of --dry-run with --read-batch.
- Fixed configure's erroneous use of target.
- Fixed configure's --disable-debug option.
- Fixed a run-time issue for systems that can't find iconv_open() by adding
the --disable-iconv-open configure option.
- Complain and die if the user tries to combine --remove-source-files (or
the deprecated --remove-sent-files) with --read-batch.
- Fixed an failure transferring special files from Solaris to Linux.
NEWS for rsync 3.0.5 (28 Dec 2008)
Protocol: 30 (unchanged)
Changes since 3.0.4:
BUG FIXES:
- Initialize xattr data in a couple spots in the hlink code, which avoids a
crash when the xattr pointer's memory happens to start out non-zero.
Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
- Don't send a bogus "-" option to an older server if there were no short
options specified.
- Fixed skipping of unneeded updates in a batch file when incremental
recursion is active. Added a test for this. Made batch-mode handle
"redo" files properly (and without hanging).
- Fix the %P logfile escape when the daemon logs from inside a chroot.
- Fixed the use of -s (--protect-args) when used with a remote source or
destination that had an empty path (e.g. "host:"). Also fixed a problem
when -s was used when accessing a daemon via a remote-shell.
- Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
file when the root of the transfer isn't the current directory.
- Fixed a bug with "-K --delete" removing symlinks to directories when
incremental recursion is active.
- Fixed a hard to trigger hang when using --remove-source-files.
- Got rid of an annoying delay when accessing a daemon via a remote-shell.
- Properly ignore (superfluous) source args on a --read-batch command.
- Improved the manpage's description of the '*' wildcard to remove the
confusing "non-empty" qualifier.
- Fixed reverse lookups in the compatibility-library version of
getnameinfo().
- Fixed a bug when using --sparse on a sparse file that has over 2GB of
consecutive sparse data.
- Avoid a hang when using at least 3 --verbose options on a transfer with a
client sender (which includes local copying).
- Fixed a problem with --delete-delay reporting an error when it was ready
to remove a directory that was now gone.
- Got rid of a bunch of "warn_unused_result" compiler warnings.
- If an ftruncate() on a received file fails, it now causes a partial-
transfer warning.
- Allow a path with a leading "//" to be preserved (CYGWIN only).
ENHANCEMENTS:
- Made the support/atomic-rsync script able to perform a fully atomic
update of the copied hierarchy when the destination is setup using a
particular symlink idiom.
NEWS for rsync 3.0.4 (6 Sep 2008)
Protocol: 30 (unchanged)
Changes since 3.0.3:
BUG FIXES:
- Fixed a bug in the hard-linking code where it would sometimes try to
allocate 0 bytes of memory (which fails on some OSes, such as AIX).
- Fixed the hard-linking of files from a device that has a device number
of 0 (which seems to be a common device number on NetBSD).
- Fixed the handling of a --partial-dir that cannot be created. This
particularly impacts the --delay-updates option (since the files cannot
be delayed without a partial-dir), and was potentially destructive if
the --remove-source-files was also specified.
- Fixed a couple issues in the --fake-super handling of xattrs when the
destination files have root-level attributes (e.g. selinux values) that
a non-root copy can't affect.
- Improved the keep-alive check in the generator to fire consistently in
incremental-recursion mode when --timeout is enabled.
- The --iconv option now converts the content of a symlink too, instead
of leaving it in the wrong character-set (requires 3.0.4 on both sides
of the transfer).
- When using --iconv, if a filename fails to convert on the receiving side,
this no longer makes deletions in the root-dir of the transfer fail
silently (the user now gets a warning about deletions being disabled
due to IO error as long as --ignore-errors was not specified).
- When using --iconv, if a server-side receiver can't convert a filename,
the error message sent back to the client no longer mangles the name
with the wrong charset conversion.
- Fixed a potential alignment issue in the IRIX ACL code when allocating
the initial "struct acl" object. Also, cast mallocs to avoid warnings.
- Changed some errors that were going to stdout to go to stderr.
- Made human_num() and human_dnum() able to output a negative number
(rather than outputting a cryptic string of punctuation).
ENHANCEMENTS:
- Rsync will avoid sending an -e option to the server if an older protocol
is requested (and thus the option would not be useful). This lets the
user specify the --protocol=29 option to access an overly-restrictive
server that is rejecting the protocol-30 use of -e to the server.
- Improved the message output for an RERR_PARTIAL exit.
DEVELOPER RELATED:
- The Makefile will not halt for just a timestamp change on the Makefile
or the configure files, only for actual changes in content.
- Changed some commands in the testsuite's xattrs.test that called "rsync"
instead of "$RSYNC".
- Enhanced the release scripts to be able to handle a branch release and
to do even more consistency checks on the files.
NEWS for rsync 3.0.3 (29 Jun 2008)
Protocol: 30 (unchanged)
Changes since 3.0.2:
BUG FIXES:
- Fixed a wildcard matching problem in the daemon when a module has
"use chroot" enabled.
- Fixed a crash bug in the hard-link code.
- Fixed the sending of xattr directory information when the code finds a
--link-dest or --copy-dest directory with unchanged xattrs -- the
destination directory now gets these unchanged xattrs properly applied.
- Fixed an xattr-sending glitch that could cause an "Internal abbrev"
error.
- Fixed the combination of --xattrs and --backup.
- The generator no longer allows a '.' dir to be excluded by a daemon-
exclude rule.
- Fixed deletion handling when copying a single, empty directory (with no
files) to a differently named, non-existent directory.
- Fixed the conversion of spaces into dashes in the %M log escape.
- Fixed several places in the code that were not returning the right
errno when a function failed.
- Fixed the backing up of a device or special file into a backup dir.
- Moved the setting of the socket options prior to the connect().
- If rsync exits in the middle of a --progress output, it now outputs a
newline to help prevent the progress line from being overwritten.
- Fixed a problem with how a destination path with a trailing slash or
a trailing dot-dir was compared against the daemon excludes.
- Fixed the sending of large (size > 16GB) files when talking to an older
rsync (protocols < 30): we now use a compatible block size limit.
- If a file's length is so huge that we overflow a checksum buffer count
(i.e. several hundred TB), warn the user and avoid sending an invalid
checksum struct over the wire.
- If a source arg is excluded, --relative no longer adds the excluded
arg's implied dirs to the transfer. This fix also made the exclude
check happen in the better place in the sending code.
- Use the overflow_exit() function for overflows, not out_of_memory().
- Improved the code to better handle a system that has only 32-bit file
offsets.
ENHANCEMENTS:
- The rsyncd.conf manpage now consistently refers to the parameters in
the daemon config file as "parameters".
- The description of the --inplace option was improved.
EXTRAS:
- Added a new script in the support directory, deny-rsync, which allows
an admin to (temporarily) replace the rsync command with a script that
sends an error message to the remote client via the rsync protocol.
DEVELOPER RELATED:
- Fixed a testcase failure if the tests are run as root and made some
compatibility improvements.
- Improved the daemon tests, including checking module comments, the
listing of files, and the ensuring that daemon excludes can't affect
a dot-dir arg.
- Improved some build rules for those that build in a separate directory
from the source, including better install rules for the man pages, and
the fixing of a proto.h-tstamp rule that could make the binaries get
rebuild without cause.
- Improved the testsuite to work around a problem with some utilities
(e.g. cp -p & touch -r) rounding sub-second timestamps.
- Ensure that the early patches don't cause any generated-file hunks to
bleed-over into patches that follow.
NEWS for rsync 3.0.2 (8 Apr 2008)
Protocol: 30 (unchanged)
Changes since 3.0.1:
BUG FIXES:
- Fixed a potential buffer overflow in the xattr code.
ENHANCEMENTS:
- None.
DEVELOPER RELATED:
- The RPM spec file was improved to install more useful files.
- A few developer-oriented scripts were moved from the support dir
to the packaging dir.
NEWS for rsync 3.0.1 (3 Apr 2008)
Protocol: 30 (unchanged)
Changes since 3.0.0:
NOTABLE CHANGES IN BEHAVIOR:
- Added the 'c'-flag to the itemizing of non-regular files so that the
itemized output doesn't get hidden if there were no attribute changes,
and also so that the itemizing of a --copy-links run will distinguish
between copying an identical non-regular file and the creation of a
revised version with a new value (e.g. a changed symlink referent, a
new device number, etc.).
BUG FIXES:
- Fixed a crash bug when a single-use rsync daemon (via remote shell) was
run without specifying a --config=FILE option.
- Fixed a crash when backing up a directory that has a default ACL.
- Fixed a bug in the handling of xattr values that could cause rsync to
not think that a file's extended attributes are up-to-date.
- Fixed the working of --fake-super with --link-dest and --xattrs.
- Fixed a hang when combining --dry-run with --remove-source-files.
- Fixed a bug with --iconv's handling of files that cannot be converted:
a failed name can no longer cause a transfer failure.
- Fixed the building of the rounding.h file on systems that need custom
CPPFLAGS to be used. Also improved the error reporting if the building
