The dependency parser was stripping environment markers but not checking
if they indicated optional or platform-specific packages. This caused
packages like jaraco.path to pull in pyobjc (324 sub-packages) even on
non-macOS systems.
Changes:
- Filter dependencies with 'extra ==' markers (optional extras)
- Filter dependencies with 'sys_platform' or 'platform_system' markers
- Add diagnostic logging for depth exceeded errors
- Add unit tests for dependency filtering
Fixes tensorflow dependency resolution exceeding max depth.
- Fix import in test_db_utils.py: use app.models instead of backend.app.models
- Update health endpoint test to expect 'ok' status and infrastructure keys
- Add CHANGELOG entries for PyPI proxy performance improvements
Add optimized database operations for artifact storage:
- Atomic upserts using ON CONFLICT for artifact creation
- Batch inserts for dependencies to eliminate N+1 queries
- Joined queries for cached URL lookups
- All methods include comprehensive unit tests
Add HttpClientManager class for managing httpx.AsyncClient pools with
FastAPI lifespan integration. Features include:
- Default shared connection pool for general requests
- Configurable max connections, keep-alive, and timeouts
- Dedicated thread pool for blocking I/O operations
- Graceful startup/shutdown lifecycle management
- Per-upstream client isolation support (for future use)
Includes comprehensive unit tests covering initialization, startup,
shutdown, client retrieval, blocking operations, idempotency, and
error handling.
- Remove Tag/TagHistory model tests from unit tests
- Update CacheSettings tests to remove allow_public_internet field
- Replace tag= with version= in upload_test_file calls
- Update test assertions to use versions instead of tags
- Remove tests for tag: prefix downloads (now uses version:)
- Update dependency tests for version-only schema
