## Summary Extras parsed from requirement strings (e.g., from `requirements.txt`) were not being normalized, causing mismatches when evaluating PEP 508 marker expressions. For example, `sqlalchemy[postgresql-psycopg2binary]` would fail to resolve `psycopg2-binary` as a transitive dependency because the wheel METADATA marker expression `extra == "postgresql_psycopg2binary"` uses the underscore-normalized form (per PEP 685), while the extras set retained the original hyphenated form from the requirement string. ## Before ``` # requirements.txt sqlalchemy[postgresql-psycopg2binary]==2.0.36 # Parsed extras: ["postgresql-psycopg2binary"] # Marker evaluation: "postgresql-psycopg2binary" != "postgresql_psycopg2binary" -> MISS # Result: psycopg2-binary NOT included as a dependency ``` ## After ``` # requirements.txt sqlalchemy[postgresql-psycopg2binary]==2.0.36 # Parsed extras: ["postgresql_psycopg2binary"] (normalized) # Marker evaluation: "postgresql_psycopg2binary" == "postgresql_psycopg2binary" -> MATCH # Result: psycopg2-binary correctly included as a dependency ``` ## Changes - **`python/private/pypi/pep508_requirement.bzl`**: Apply `normalize_name()` to each extra during requirement parsing, consistent with how the package name is already normalized. - **`tests/pypi/pep508/requirement_tests.bzl`**: Updated existing test expectation for case normalization and added test case for hyphenated extras (`sqlalchemy[asyncio,postgresql-psycopg2binary,postgresql-asyncpg]`). - **`tests/pypi/pep508/deps_tests.bzl`**: Added `test_extras_with_hyphens_are_normalized` integration test confirming that dependencies gated behind hyphenated extras are correctly resolved. - **`CHANGELOG.md`**: Added entry under Unreleased > Fixed.
