Code Review
This pull request updates the rules_cc dependency from version 0.1.5 to 0.2.17 across multiple configuration files, including MODULE.bazel, internal_dev_deps.bzl, python/private/py_repositories.bzl, and the integration test module. This update is necessary to expose cc/toolchains:feature_injection.bzl for RBE support. I have no further feedback to provide.
RBE on BazelCI has been failing for every recent PR with:
ERROR: error loading package '@@+internal_dev_deps+buildkite_config//cc':
.../cc_toolchain_config.bzl:35:6:
cannot load '@@rules_cc+//cc/toolchains:feature_injection.bzl': no such file
BazelCI's injected `buildkite_config//cc/cc_toolchain_config.bzl`
unconditionally loads `feature_injection.bzl`, which was added in
`rules_cc` 0.2.17 (commit 64024621, 2026-02-11). The previously-pinned
0.1.5 does not have it, so RBE jobs fail at analysis time.
Bump the bzlmod and WORKSPACE/`http_archive` pins everywhere `rules_cc`
is declared: `MODULE.bazel`, `python/private/py_repositories.bzl`,
`internal_dev_deps.bzl`, and `tests/integration/local_toolchains/MODULE.bazel`.
All `@rules_cc//...` load paths used by rules_python are unchanged in
0.2.17.

Why
RBE has been failing on every recent build (e.g.
mainHEAD build 15455) with:BazelCI's injected
buildkite_config//cc/cc_toolchain_config.bzlnow loadsfeature_injection.bzlunconditionally. That file landed inrules_cc0.2.17; the current pin is 0.1.5. RBE uses bzlmod (see.bazelrc), so the bzlmod pin is what matters.What changed
Bzlmod
rules_ccpin only:0.1.5→0.2.17inMODULE.bazelandtests/integration/local_toolchains/MODULE.bazel.WORKSPACE
http_archivepins are intentionally left at0.1.5. Bumping them broke 22 jobs in the first push to this PR (build 15462) becauserules_cc0.2.17 requires WORKSPACE consumers to also callcompatibility_proxy_repo()— a breaking change for downstream users. WORKSPACE jobs don't use RBE in this repo.Test plan
Reproduced both the original RBE break and the workspace regression in a Docker container, then verified the split-pin fix locally:
