Summary by Sourcery

Harden storage APIs and file-location resolution against unauthorized access, incorrect backend selection, and overly permissive S3 configuration.

New Features:

  • Add centralized authorization and validation checks to storage modification APIs, including feature-flag enforcement, record ownership, bucket/object validation, and replacement-target validation.
  • Handle expired sessions and non-JSON responses consistently in storage API client requests.
  • Strengthen newly created S3 buckets with restricted public ACL behavior and read-only public object access.

Bug Fixes:

  • Prevent storage location resolution from selecting incorrect credentials for similarly prefixed URIs and fall back safely when no location matches.

Enhancements:

  • Replace full in-memory location scans with boundary-aware, longest-prefix database queries and explicit default-location handling.

Tests:

  • Expand storage and storage API coverage for authorization, validation failures, feature flags, location matching boundaries, fallback behavior, and S3 policies.

Chores:

  • Ensure test databases are recreated cleanly and isolate audit logging from unavailable partitioned tables during tests.

Summary by CodeRabbit

  • New Features

    • Added stronger validation for institutional storage operations, including record ownership, bucket/file existence, and destination checks.
    • Improved handling of expired sessions and invalid server responses in storage-related actions.
    • Added clearer permission-denied messaging.
  • Bug Fixes

    • Improved storage location selection with exact, boundary-aware matching, longest-prefix preference, and reliable fallback behavior.
    • Restricted generated bucket policies to object retrieval while blocking public ACLs.
    • Improved error handling for bucket, file, copy, and replacement operations.
  • Translations

    • Updated English and Japanese translation catalogs with the new permission message.

- Add @login_required to get_bucket_list, copy_bucket, get_file_place
  and replace_file
- Add _validate_storage_api_request(), which checks the feature flag,
  record ownership, base recid and request parameters in that order
- Verify bucket_id, file_name, new_bucket_id and new_version_id belong
  to the record identified by pid
- Return 403 with a single shared message; log the reason separately
- Hoist shared parameters in replace_file so both branches are checked
- Register the new msgid in the translation catalogs

Align the create_storage_bucket tests with the read-only policy applied
in ccc1222: BlockPublicAcls and IgnorePublicAcls are now True, and the
bucket policy action is s3:GetObject.

Strengthen the non-default-region and non-AWS-endpoint cases, which only
asserted that the calls happened, so they now verify the public access
block configuration and the policy action as well.

- Require a separator right after Location.uri, so s3://bucket-a no
  longer matches s3://bucket-a2 and supplies the wrong S3 credentials
- Keep the substr equality comparison (no LIKE) and the longest-match
  ordering unchanged
- Add regression tests for similar bucket names, trailing-slash URIs,
  local path boundaries and exact URI matches

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- Require pid on the record-scoped APIs and return 403 when it is
  missing; only get_bucket_list opts out via feature_flag_only
- Require new_bucket_id and new_version_id together, since
  ObjectVersion.get falls back to the head version without
  version_id

Update the legacy storage API tests

WEKO_RECORDS_UI_USER_STORAGE_MODIFICATION_ENABLED defaults to False. These legacy tests do not override the flag or mock _validate_storage_api_request, so the validator returns 403 before the storage backend runs. Enable the flag and mock the validator, or remove the duplicate tests.

Restore the feature flag after each test.

_setup_storage_api writes to app.config and never restores the previous value. The base_app fixture is shared, so the enabled flag leaks into later tests in the session and creates order-dependent results. Use monkeypatch.setitem or save and restore the value.

1794-1794: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Update legacy backend tests for the centralized validation gate.

These tests now run validation before the mocked backend. Their legacy payloads can return 403 before the expected backend response.

  • modules/weko-records-ui/tests/test_views.py#L1794-L1794: rename file_name to filename and mock validation, or construct a fully valid request.
  • modules/weko-records-ui/tests/test_views.py#L2113-L2114: mock validation for the S3 success-path backend test, or provide a valid detached destination object.
  • modules/weko-records-ui/tests/test_views.py#L2128-L2129: apply the same setup to the S3 backend-error test.

こちらのプルリクエストで行った権限チェック・バリデーションについて、develop_v2.0.4 に issues/#62569 で追加されたデコレータによる権限チェックと重複・競合するものが複数ありました。そのため、CodeRabbit の指摘への対応と合わせて、デコレータでチェックされる項目についてこのプルリクエストから削除する方針でよろしいでしょうか。

- Drop the pid presence and check_created_id checks; the
  record_edit_permission_required decorator (2f6b61b) runs first
- Keep the storage-specific checks the decorator does not cover
- Update the tests to the decorator's responses and drop the ones
  covering the removed checks
- Rewrite the docstring in Google style

- split the destination checks out of _validate_storage_api_request into
  _validate_new_file_target so the S3 branch always validates its target
- extract _check_storage_feature_flag and drop the feature_flag_only flag,
  reducing _validate_storage_api_request from 6 arguments to 3 required ones
