ci: free disk space before embeddings-all builds (#775)#776
Merged
Conversation
The ubuntu-latest x86_64 jobs that build --features embeddings-all (candle / tokenizers / hf-hub / image / reqwest) intermittently died with "No space left on device": the restored Rust cache plus the build artifacts exceed the runner's root disk by a thin margin. aarch64 (skip_embedding_features) and Windows are unaffected. Add a reusable composite action .github/actions/free-disk-space that removes unused preinstalled toolchains (.NET, Android SDK, GHC/Haskell, CodeQL bundle) and dangling Docker images (~25-30 GB) and prints free space before/after. Reference it (Linux-gated, right after checkout) in the heavy embeddings-all jobs (clippy + test-*) of regression.yml, periodic.yml, and release.yml. Removed paths are unused by the Rust / Python / Node toolchains these jobs rely on. Closes #775

Summary
The
ubuntu-latestx86_64 CI jobs that build--features embeddings-all(candle / tokenizers / hf-hub / image / reqwest) intermittently die withNo space left on device. The restored Rust build cache (~790 MB compressed, much larger expanded) plus theembeddings-allbuild artifacts exceed the runner's root disk by a thin margin, so the failure is intermittent. Theubuntu-24.04-armjob is unaffected (skip_embedding_features: true) and Windows is unaffected (different disk layout). Observed on PRs #772 and #774; cause is only visible viagh api repos/.../check-runs/<job_id>/annotations.Change
.github/actions/free-disk-spacethat removes unused preinstalled toolchains (.NET, Android SDK, GHC/Haskell, CodeQL bundle) and dangling Docker images (~25-30 GB reclaimed), printingdf -h /before and after so future disk regressions are diagnosable from the log. This follows the existing local-composite-action pattern (./.github/actions/install-protoc).if: runner.os == 'Linux', right after checkout — in the heavyembeddings-alljobs ofregression.yml,periodic.yml, andrelease.yml:clippy,test-laurus,test-server,test-mcp,test-cli,test-python,test-nodejs,test-ruby,test-php(9 jobs × 3 workflows = 27 references).The removed paths are unused by the Rust / Python / Node toolchains these jobs rely on. Because
pull_requestruns use the PR's own workflow definitions, this change self-validates — theFree disk spacestep runs on this PR's CI.Verification
