Summary

  • Add timeout-minutes to every job in checks.yml, firebase-hosting-merge.yml, firebase-hosting-pull-request.yml, cats.yml, and search-trigger.yml so a genuinely hung job fails fast instead of blocking the runner/queue indefinitely.
  • Split all actions/cache@v4 usages in checks.yml and both firebase-hosting workflows into the explicit restore + save pattern (save moved to end of job, if: always(), continue-on-error: true, own timeout-minutes: 5) to avoid the known post-run cache-save hang. path/key/restore-keys left unchanged.

Jobs touched and timeout values chosen

  • checks.yml
    • codeFormatting (yarn format:check) — 10m
    • codeStyles (yarn lint) — 10m
    • types (yarn typecheck) — 10m
    • tests (yarn test --coverage + codecov upload) — 15m
    • e2e (yarn build + playwright install + e2e tests) — 20m
  • firebase-hosting-merge.yml: build_and_deploy (build + Firebase live deploy) — 20m
  • firebase-hosting-pull-request.yml: build_and_preview (build + Firebase preview deploy) — 20m
  • cats.yml: aCatForCreatingThePullRequest (single third-party action call) — 5m
  • search-trigger.yml: updateSearchIndex (Algolia docsearch crawl trigger) — 10m

Validation

  • actionlint (installed globally) run against all 5 edited workflow files — no errors.
  • All 5 files also parsed successfully with Python yaml.safe_load.

Test plan

  • Confirm workflows still trigger and pass normally on this branch's own checks/PR run
  • Confirm cache restore/save steps still populate and hit cache on subsequent runs

Summary by CodeRabbit

  • CI/CD Improvements
    • Added execution time limits across automated validation, deployment, pull request, and search-index workflows.
    • Improved dependency caching to restore and save caches independently.
    • Ensured cache-saving steps run even when earlier steps fail, while allowing cache errors without blocking workflows.

Add timeout-minutes to every job in checks.yml, firebase-hosting-merge.yml,
firebase-hosting-pull-request.yml, cats.yml, and search-trigger.yml so a
hung job fails fast instead of blocking the runner queue indefinitely.

Also split actions/cache@v4 usage in checks.yml and both firebase-hosting
workflows into the explicit restore + save pattern, moving the save to the
end of each job with continue-on-error and its own timeout, to avoid the
known post-run cache-save hang.

Review Change Stack

📝 Walkthrough

Walkthrough

The workflows add explicit job timeouts. The checks and Firebase hosting workflows split Yarn cache restoration and saving into separate actions. Cache saves run after failures, tolerate errors, and have five-minute limits.

Changes

CI workflow controls

Layer / File(s) Summary
Checks workflow timeouts and cache saves
.github/workflows/checks.yml
The five checks jobs now have explicit timeouts. Each Yarn cache uses separate restore and save actions. Cache saves always run, allow errors, and have five-minute limits.
Hosting workflow timeouts and cache saves
.github/workflows/firebase-hosting-merge.yml, .github/workflows/firebase-hosting-pull-request.yml
Firebase hosting jobs now have 20-minute limits. Yarn caches restore and save through separate actions after installation.
Ancillary workflow execution limits
.github/workflows/cats.yml, .github/workflows/search-trigger.yml
The pull-request-target job has a five-minute limit. The search-index job has a ten-minute limit.

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

Merge Risk: ⚪ Minimal · up to 837ba

This PR bounds CI execution and separates cache restoration from saving without introducing new permissions or deployment behavior. The existing Codecov security concerns are not introduced or expanded by this change, so no actionable merge-blocking risk remains beyond normal checks.

Codecov Bash uploader deprecated official documentation codecov.io/bash current

💡 Result:

The Codecov Bash uploader has been officially deprecated and superseded by the Codecov CLI (Command Line Interface) [1][2]. Key information regarding this transition: 1. Status: The Bash uploader is no longer maintained or supported for new features, and users are strongly advised to migrate to the Codecov CLI [1][3]. 2. Migration: Codecov provides a dedicated migration guide for users transitioning away from the Bash uploader [4]. This involves replacing legacy Bash uploader calls with the modern Codecov CLI, which now powers the official Codecov integrations for CI/CD environments such as GitHub Actions, CircleCI, and Bitrise [1][2]. 3. Recommended Tools: For CI/CD environments, Codecov recommends using the latest versions of their official integrations (e.g., version 4.0.0+ for the GitHub Action, CircleCI Orb, and Bitrise Step), which utilize the CLI internally [2]. 4. Documentation: You can find the official guidance and migration steps in the Codecov documentation portal [4][1]. As of August 31, 2026, you should avoid using the legacy Bash uploader and instead update your CI pipelines to use the current Codecov CLI-based upload methods [1][2].
