PyPI packages can have self-referential dependencies for extras
(e.g., pytest[testing] depends on pytest). These were incorrectly
detected as circular dependencies. Now we skip them.
When dependencies are not cached on the server (common since we removed
proactive caching), the dependency graph now:
- Continues resolving what it can find
- Shows missing dependencies in a separate section with amber styling
- Displays the constraint and which package required them
- Updates the header stats to show "X cached • Y not cached"
This provides a better user experience than showing an error when
some dependencies haven't been downloaded yet.
When a dependency has an invalid version constraint like '>=' (without
a version number), the resolver now treats it as a wildcard and returns
the latest available version instead of failing with 'Dependency not found'.
This handles malformed metadata that may have been stored from PyPI packages.
- Deduplicate dependencies by package name before inserting
- Some packages (like anyio) list the same dep (trio) multiple times with
different version constraints for different extras
- The unique constraint on (artifact_id, project, package) rejected these
- Also removed debug logging from dependencies.py
- Parse version constraints like >=1.9, <2.0 using packaging library
- Find the latest version that satisfies the constraint
- Support wildcard (*) to get latest version
- Fall back to exact version and tag matching
