📝 Walkthrough

Walkthrough

The PostgreSQL workflow replaces manual coverage commands with the reusable uv-pytest-coverage action for serial and xdist tests. A news fragment documents the migration.

Changes

Coverage workflow migration

Layer / File(s)	Summary
Reusable coverage action migration .github/workflows/single-postgres.yml, newsfragments/1424.misc.rst	The workflow uses uv-pytest-coverage for serial and xdist tests. Serial coverage defines its data and XML output files. Manual combine-and-export steps are removed. The news fragment records the migration.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 63c53

The CI coverage workflow now relies on mutable nested action references and may run the parallel coverage job without the configuration needed to generate the expected coverage data, risking non-reproducible CI execution and incorrect coverage artifacts. Pin the nested references and pass .coveragerc before merging.

In @.github/workflows/single-postgres.yml:
- Around line 80-87: Update the uv-pytest-coverage action usage in the workflow
so its nested uv-run and coverage-combine-export-uv dependencies are referenced
by immutable commit SHAs rather than mutable v5.6.0 tags; otherwise vendor the
composite action with equivalent SHA-pinned references, while preserving the
existing pytest configuration.
- Around line 85-87: Update the uv-pytest-coverage action invocation to provide
.coveragerc through its coverage-config input, while preserving the existing
pytest-opts and xdist settings so workers generate separate coverage data for
coverage-xdist.xml.
