[Storage Blob] Migrating to TypeSpec by l0lawrence · Pull Request #45133 · Azure/azure-sdk-for-python

l0lawrence · 2026-02-11T16:57:23Z

Mindependency failure for storage datalake is due to storage blob 1.31.1b1 not being released
_models/_patch.py: patching new, getattr, setattr for backcompat with old autorest models so that the _models.py publicly used in storage blob and file-datalake work as is -- going to change file-datalake when it gets ported to not use the generated models but rather the public models from azure-storage-blob

Recommended actions (copilot given)

Delete azure/storage/blob/_validation.py (duplicate of _generated/_validation.py).
Scope the monkey-patching in _generated/models/_patch.py: patch only the storage-blob model classes (e.g. iterate _models subclasses) instead of _Model/_MyMutableMapping at the framework level. If that's infeasible, at minimum document the global side effect prominently
and confirm with the core team.
Reconsider _patched_as_dict: either (a) keep the typespec default keys (camelCase) and add a separate backcompat method, or (b) honor key_transformer rather than silently ignoring it.
parse_page_list: keep raising when the response is genuinely malformed (both None together, or neither is a list) rather than silently returning [].
blob.metadata filter: derive the excluded-field set from the generated model rather than hardcoding "Encrypted".
AzureBlobStorage.init: confirm None-in-policies-list behavior, and add a test asserting the patched default API version matches the underlying generated configuration's default.

…rClient The prior fix for the AccessPolicy leak in get_container_access_policy referenced AccessPolicy at runtime but only imported it under TYPE_CHECKING, causing NameError when the sync code path was hit. Also apply the same items_property/_from_generated wrap to the async get_container_access_policy, which was still returning the generated AccessPolicy directly. Verified against azure-cli storage tests (recorded mode): fixes test_storage_blob_container_operations, test_storage_container_acl_scenarios, and test_storage_container_access_policy_scenario.
