Change Log azure-storage-file

Version 12.0.0b2:

Breaking changes

  • Renamed copy_file_from_url to start_copy_from_url and changed behaviour to return a dictionary of copy properties rather than a polling object. Status of the copy operation can be retrieved with the get_file_properties operation.
  • Added abort_copy operation to the FileClient class. This replaces the previous abort operation on the copy status polling operation.
  • The behavior of listing operations has been modified:
    • The previous marker parameter has been removed.
    • The iterable response object now supports a by_page function that will return a secondary iterator of batches of results. This function supports a continuation_token parameter to replace the previous marker parameter.
  • The new listing behaviour is also adopted by the receive_messages operation:
    • The receive operation returns a message iterator as before.
    • The returned iterator supports a by_page operation to receive messages in batches.

New features

  • Added async APIs to subnamespace azure.storage.file.aio.
  • Distributed tracing framework OpenCensus is now supported.

Dependency updates

  • Adopted azure-core 1.0.0b2

    • If you later want to revert to azure-storage-file 12.0.0b1, or another Azure SDK library requiring azure-core 1.0.0b1, you must explicitly install azure-core 1.0.0b1 as well. For example:

    pip install azure-core==1.0.0b1 azure-storage-file==12.0.0b1

Fixes and improvements

  • Fix for closing file handles - continuation token was not being passed to subsequent calls.
  • General refactor of duplicate and shared code.

Version 12.0.0b1:

Version 12.0.0b1 is the first preview of our efforts to create a user-friendly and Pythonic client library for Azure Storage Files. For more information about this, and preview releases of other Azure SDK libraries, please visit https://aka.ms/azure-sdk-preview1-python.

Breaking changes: New API design

  • Operations are now scoped to a particular client:

    • FileServiceClient: This client handles account-level operations. This includes managing service properties and listing the shares within an account.
    • ShareClient: The client handles operations for a particular share. This includes creating or deleting that share, as well as listing the directories within that share, and managing properties and metadata.
    • DirectoryClient: The client handles operations for a particular directory. This includes creating or deleting that directory, as well as listing the files and subdirectories, and managing properties and metadata.
    • FileClient: The client handles operations for a particular file. This includes creating or deleting that file, as well as upload and download data and managing properties.

    These clients can be accessed by navigating down the client hierarchy, or instantiated directly using URLs to the resource (account, share, directory or file). For full details on the new API, please see the reference documentation.

  • The copy file operation now returns a polling object that can be used to check the status of the operation, as well as abort the operation.

  • The close_handles operation now return a polling object that can be used to check the status of the operation.

  • Download operations now return a streaming object that can download data in multiple ways:

    • Iteration: The streamer is an iterable object that will download and yield the content in chunks. Only supports single threaded download.
    • content_as_bytes: Return the entire file content as bytes. Blocking operation that supports multi-threaded download.
    • content_as_text: Return the entire file content as decoded text. Blocking operation that supports multi-threaded download.
    • download_to_stream: Download the entire content to an open stream handle (e.g. an open file). Supports multi-threaded download.

  • New underlying REST pipeline implementation, based on the new azure.core library.

  • Client and pipeline configuration is now available via keyword arguments at both the client level, and per-operation. See reference documentation for a full list of optional configuration arguments.

  • New error hierarchy:

    • All service errors will now use the base type: azure.core.exceptions.HttpResponseError
    • The are a couple of specific exception types derived from this base type for common error scenarios:
      • ResourceNotFoundError: The resource (e.g. queue, message) could not be found. Commonly a 404 status code.
      • ResourceExistsError: A resource conflict - commonly caused when attempting to create a resource that already exists.
      • ResourceModifiedError: The resource has been modified (e.g. overwritten) and therefore the current operation is in conflict. Alternatively this may be raised if a condition on the operation is not met.
      • ClientAuthenticationError: Authentication failed.

  • Operation set_file_properties has been renamed to set_http_headers.

  • Operations get_file_to_<output> have been replaced with download_file. See above for download output options.

  • Operations create_file_from_<input> have been replace with upload_file.

  • Operations get_share_acl and set_share_acl have been renamed to get_share_access_policy and set_share_access_policy.

  • Operation set_share_properties has been renamed to set_share_quota.

  • Operation snapshot_share has been renamed to create_snapshot.

  • Operation copy_file has been renamed to copy_file_from_url.

  • No longer have specific operations for get_metadata - use get_properties instead.

  • No longer have specific operations for exists - use get_properties instead.

  • Operation update_range has been renamed to upload_range.

Version 2.0.1:

  • Updated dependency on azure-storage-common.

Version 2.0.0:

  • Support for 2018-11-09 REST version. Please see our REST API documentation and blogs for information about the related added features.
  • Added an option to get share stats in bytes.
  • Added support for listing and closing file handles.

Version 1.4.0:

  • azure-storage-nspkg is not installed anymore on Python 3 (PEP420-based namespace package)

Version 1.3.1:

  • Fixed design flaw where get_file_to_* methods buffer entire file when max_connections is set to 1.

Version 1.3.0:

  • Support for 2018-03-28 REST version. Please see our REST API documentation and blog for information about the related added features.

Version 1.2.0rc1:

  • Support for 2017-11-09 REST version. Please see our REST API documentation and blog for information about the related added features.

Version 1.1.0:

  • Support for 2017-07-29 REST version. Please see our REST API documentation and blogs for information about the related added features.
  • Error message now contains the ErrorCode from the x-ms-error-code header value.

Version 1.0.0:

  • The package has switched from Apache 2.0 to the MIT license.
  • Fixed bug where get_file_to_* cannot get a single byte when start_range and end_range are both equal to 0.
  • Metadata keys are now case-preserving when fetched from the service. Previously they were made lower-case by the library.
