Azure Storage Client Library for C++
History of Changes
Changes in v5.0.0
- Dropped the support for Nuget package with name 'wastorage', now this client library only release with Nuget name 'Microsoft.Azure.Storage.CPP'.
- Added support for specifying installation destination when compiling with cmake to resolve feature request #183.
- Enabled CMake on Windows.
- Added check for metadata name that is empty or contains whitespaces to fail fast, and trimmed beginning/trailing whitespaces for metadata value.
- Resolved an issue where partial xml body will not throw exception when being parsed.
- Resolved an issue where retry for Table's batch operation always returns the first response.
Changes in v4.0.0:
- Fixed an issue where blob names that only contains space cannot be listed properly.
- Added more compiler setting to unblock ApiScanning.
- Added a new `nuspec` set that will release `Microsoft.Azure.Storage.CPP` and modified the `wastorage`'s nuspec to depend on Microsoft.Azure.Storage.CPP. Note that 4.0.0 will be the last version of `wastorage`. We strongly advice our user to use Nuget package `Microsoft.Azure.Storage.CPP` start from 4.0.0
- Resolved an issue where 3rd attempt of retry to download a blob or file will write more data than expected to destination stream.
- Removed dependency on `libxml++` for Linux platforms. But now this SDK depends on `libxml2`, which is available for most Linux distributions.
- `azure::storage::file::upload_properties` and `azure::storage::file::upload_properties_async` will no longer resize a file, even when properties contains length that is being set to 0 or other values.
Changes in v3.2.1:
- Added tag `<requireLicenseAcceptance>true</requireLicenseAcceptance>` in .nuspec files and modified the author to `Microsoft` to comply to the new Microsoft Nuget package rule set. Note that this will require the Nuget package user to accept the license manually when newly installing or upgrading 3.2.1 version (and on) of this client library.
Changes in v3.2:
- Added support for blob archive feature, which includes following changes:
- Added two new APIs for `cloud_blob` to support copying a blob to a new destination setting premium access tier, note that currently, only premium page blobs are supported so these two APIs should only be used for page blobs.
- `utility::string_t start_copy(const web::http::uri& source, const azure::storage::premium_blob_tier tier, const access_condition& source_condition, const access_condition& destination_condition, const blob_request_options& options, operation_context context)`.
- `pplx::task<utility::string_t> start_copy_async(const web::http::uri& source, const premium_blob_tier tier, const access_condition& source_condition, const access_condition& destination_condition, const blob_request_options& options, operation_context context)`.
- Added two new APIs for block blob to support setting the standard blob tier.
- `void set_standard_blob_tier(const standard_blob_tier tier, const access_condition & condition, const blob_request_options & options, operation_context context)`
- `pplx::task<void> set_standard_blob_tier_async(const standard_blob_tier tier, const access_condition & condition, const blob_request_options & options, operation_context context)`
- Added two new APIs for page blob to support setting the premium blob tier.
- `void set_premium_blob_tier(const premium_blob_tier tier, const access_condition & condition, const blob_request_options & options, operation_context context)`
- `pplx::task<void> set_premium_blob_tier_async(const premium_blob_tier tier, const access_condition & condition, const blob_request_options & options, operation_context context)`
- `cloud_blob_properties` now contains 4 more attributes: ` standard_blob_tier`, `premium_blob_tier`, `archive_status`, `access_tier_inferred`. They will be updated using `download_attributes`, and will be set to server returned value when calling `list_blobs`.
- Added two new APIs to support creating page blob with premium access tier.
- `pplx::task<void> create_async(utility::size64_t size, const premium_blob_tier tier, int64_t sequence_number, const access_condition& condition, const blob_request_options& options, operation_context context)`
- `void create(utility::size64_t size, const premium_blob_tier tier, int64_t sequence_number, const access_condition& condition, const blob_request_options& options, operation_context context)`

- cloud_page_blob::open_write
- cloud_page_blob::upload_from_stream
- cloud_page_blob::upload_from_file
- The client checks blob lease times and throws std::invalid_argument for invalid lease times. Previously, this would have been checked on the service and azure::storage::storage_exception would have been thrown.
- Improvements on error handling:
- azure::storage::storage_exception now has inner_exception populated with the actual underlying exception thrown
- azure::storage::storage_exception now has more information about errors on storage service side
- was/error_code_strings.h is added including messages for all possible error codes from storage service
- Improvements on Unit Tests:
- All test cases now print out test name and client reqeust ID
- Added new cases for containers listing and continuation token
- Unit Test configuraiton file is copied to output directory via CMake now, so no need to copy it manually under Linux
- Several fixes for bugs:
- Cannot generate SAS tokens for tables with upper-case letters in table name
- cloud_blob_istreambuf and cloud_blob_ostreambuf is set to a wrong position after seek() method is called.
- Content-MD5 header is incorrectly set when sending Put Page requests with page-write set to clear

- Performance improvement when uploading and downloading blobs.
- Added const version of the operation_context::user_headers() function.
- Fixed incorrect initialization of some members in the cloud_blob_container_properties and retry_info classes.
- Added a default of 24 days for a maximum execution time for an operation
- Changed the exception type if you upload a blob from a seekable stream but the stream is too short for the desired blob length.
- Used to throw azure::storage::storage_exception in some cases, now throws std::invalid_argument always.
- Now checks for this case explicitly before the upload is started.
- Non-seekable streams still throw std::invalid_argument as before.
- Fixed several bugs, including incorrect uses of std::move and compile-time differences between Visual Studio and g++.
- Added client request ID into log lines.
- Upgraded Casablanca dependency to 2.3.0

- Added download_to_file_async function in cloud_blob class.
- Added upload_from_file_async function in cloud_block_blob and cloud_page_blob classes.
- The HTTP status code and extended error information are populated when the table service returns an error.
- The SAS token returned by the get_shared_access_signature functions does not include a question mark (?) prefix.
- The storage_credentials class stores SAS tokens without a question mark (?) prefix.
- Added support for accepting SAS URIs to tables and queues.
- Fixed error where table query filter strings containing special characters were not encoded correctly.
- Fixed intermittent error where authentication fails when trying to update a queue message.
- Fixed a race condition causing invalid handle errors when sending parallel requests right after loading the module.
- The ETag is populated on table entities returned from table retrieve operations.
- Changed retry policies to not retry when HTTP status code 408 is received.
- Added check to prevent uploading metadata values that are empty or consist entirely of whitespace.
- Changed the storage_uri class to permit specifying only a secondary URI.
- No value is set for the server timeout by default, which means the service's default value will be in affect unless the caller specifies a value.
- Added more parameter validation.
- Removed the constness from the return values of binary_value, datetime_value, guid_value, and string_value functions in entity_property class.
- Removed the constness from the return values of filter_string and select_columns functions in table_query class.
- Changed many functions to accept pass-by-value arguments to support move semantics.
- Changed many functions to accept pass-by-reference arguments or return references as a performance improvement.
- Made some constructors explicit to avoid implicit conversions. This affects these classes:
canonicalizer, shared_key_blob_queue_canonicalizer, shared_key_lite_blob_queue_canonicalizer, shared_key_table_canonicalizer,
shared_key_lite_table_canonicalizer, sas_authentication_handler, shared_key_authentication_handler, continuation_token,
