Summary

• Fix the Docker image cache. It never saved: on a miss actions/cache sets cache-hit to an empty string, not 'false', so the save step was always skipped and no docker-images-* cache entry exists. Every infra job pulled every image from the registries, which is what the cache was added to avoid (429 throttling).
• Use the latest uv and Supabase CLI. uv was pinned to 0.8.2 and never updated, since Dependabot only bumps action references and not their version: inputs. The installed CLI version is part of the Docker image cache key, so a CLI release that changes image versions does not reuse stale images.
• Stop starting unused services. realtime now disables storage, studio, mailpit, edge runtime and analytics in its config. storage disables auth. -x alone still pulled storage-api and postgres-meta for realtime and gotrue for storage. Verified locally: realtime runs 5 containers and passes 43 tests, storage passes 109 tests.
• Add a lint job running ruff check and ruff format --check. Ruff did not run in CI before.
• Smaller savings. The Supabase CLI is only installed for realtime and storage, the port reservation only runs where the CLI is used, and pyrefly runs in parallel with the infra start (make -j2). Dependencies are synced in their own step first so the parallel uv run calls never write the environment or uv.lock at the same time.
• Test only affected packages on pull requests. A new changes job (.github/scripts/ci_matrix.py) builds the matrix from the pull request diff: a changed package plus its dependents (utils affects everything, every package affects supabase). Documentation and non-CI .github changes test nothing, and any other file outside src/<pkg>/ tests everything. Pushes to main and manual runs always test everything. Coveralls carries forward the coverage of untested packages, and a CI passed job gives a single status to require, since the set of test jobs now varies.

Note: test job names lose the @ ubuntu-latest suffix and Coveralls flag names change, so carried forward coverage starts working after the first main build with this change. No ruleset requires specific check names today.

Test plan

• All 35 test jobs run on this PR, since it changes ci.yml
• The infra jobs save a docker-images-* cache, and a rerun loads it
• realtime and storage pass with the reduced service sets

Summary

Summary by CodeRabbit

• Chores
  • CI now runs lint checks and selects tests based on the changes in a pull request; other runs test all packages.
  • Test jobs use parallel execution, and coverage results are carried forward for packages not tested.
  • Several services are disabled in the local Supabase configurations, including Realtime, Storage, and Auth.

The CI workflow now selects package tests from changed paths, runs lint checks, and updates coverage and release gates. Local Supabase configurations disable selected services in the Realtime and Storage projects.
