Storage Client Library v0.5.0

Changes in v0.5:

• Default REST API version is 2014-02-14
• Added parameter sequence_number to the following functions:
  • cloud_page_blob::create_async

  • cloud_page_blob::create
  • 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

Storage Client Library v0.4.0

Changes in v0.4:

• Now supports building on Linux
• Added http_buffer_size request option to control the internal buffer size used in the HTTP layer when downloading data. The default size is 64KB.
• Blob downloads that are interrupted resume automatically from where the download left off when being retried.
• 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

Storage Client Library v0.3.0

Changes in v0.3:

• Changed namespace to azure::storage.
• Added support for secondary location access in Azure Storage Emulator.
• Added support for downloading service stats for blob, table, and queue services to check geo-replication status.
• 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, retry_info, retry_policy, cloud_queue_message, cloud_queue_client,
  basic_common_retry_policy, cloud_client
• Major performance improvement when executing many requests in parallel.
• Minor bug fixes and performance improvements.
