This does two things:
- We use `persist-credentials: false` everywhere now. This is
unfortunately not the default in GitHub Actions, but it prevents
`actions/checkout` from dropping `secrets.GITHUB_TOKEN` onto disk.
- We interpose (some) template expansions through environment variables.
I've limited this to contexts that have non-fixed values; contexts that
are fixed (like `*.result`) are not dangerous to expand directly inline
(but maybe we should clean those up in the future for consistency
anyways).
This is a medium-risk change in terms of CI breakage: I did a scan for
usage of `git push` and other commands that implicitly use the persisted
credential, but couldn't find any. Even still, some implicit usages of
the persisted credentials may be lurking. Please ping ww@ if any issues
arise.
This builds on top of https://github.com/openai/codex/pull/15828 by
ensuring that hash-pinned actions with version comments are fully
qualified, rather than referencing floating/mutable comments like "v7".
This makes actions management tools behave more consistently.
This shouldn't break anything, since it's comment only. But if it does,
ping ww@ 馃檪
## Summary
This is the first PR in the V8 in-process sandboxing rollout.
It adds the build-system and Rust feature plumbing needed to support
sandboxed V8 builds, then enables sandboxing by default for the
source-built Bazel V8 path that we control directly. It deliberately
keeps the published `rusty_v8` artifact workflows on their current
non-sandboxed contract so this PR can land and ship independently before
we change any released artifacts.
## Rollout plan
- [x] **PR 1: land sandbox plumbing and default source-built Bazel V8 to
sandboxed mode**
- [ ] **PR 2: publish sandbox-enabled release artifacts and add
compatibility validation**
- Produce sandboxed artifact pairs for every released Cargo target that
does not already use the source-built Bazel path.
- Add CI coverage that consumes those sandboxed artifacts and verifies:
- `codex-v8-poc` reports sandbox enabled
- `codex-code-mode` builds/tests against the sandboxed path
- [ ] **PR 3: switch release consumers to sandboxed artifacts by
default**
- Update released artifact selectors/checksums.
- Enable the Rust `v8_enable_sandbox` feature in the default release
path.
- Make the sandboxed artifact family the normal path for published
builds.
- [ ] **PR 4: remove rollout-only compatibility paths**
- Remove the temporary non-sandbox release compatibility config once the
new default has shipped and baked.
- Keep the invariant tests permanently.
## Why
All Bazel CI jobs are currently blocked in the `setup-bazelisk` step
while trying to download Bazelisk.
[`bazelbuild/setup-bazelisk`](https://github.com/bazelbuild/setup-bazelisk)
is archived, and its README now recommends migrating to
[`bazel-contrib/setup-bazel`](https://github.com/bazel-contrib/setup-bazel),
so leaving our workflows on the archived action leaves CI exposed to
exactly this sort of outage.
Because `v8-canary` now consumes the shared local `setup-bazel-ci`
action, that workflow also needs to trigger when the action changes.
Without that follow-up, Bazel bootstrap regressions specific to the V8
canary path could be skipped by the workflow path filters.
## What Changed
- Switched `.github/actions/setup-bazel-ci/action.yml` from
`bazelbuild/setup-bazelisk` to `bazel-contrib/setup-bazel`, pinned to
`0.19.0`.
- Left `bazelisk-version` unset so GitHub-hosted runners can use their
preinstalled Bazelisk instead of downloading `1.x` at job start.
- Updated `.github/workflows/rusty-v8-release.yml` and
`.github/workflows/v8-canary.yml` to use the shared `setup-bazel-ci`
action instead of referencing `setup-bazelisk` directly.
- Added `.github/actions/setup-bazel-ci/**` to the `pull_request` and
`push` path filters in `.github/workflows/v8-canary.yml` so changes to
the shared Bazel setup action still run the canary workflow.
- Kept the existing repository-cache and Windows-specific Bazel setup
logic intact.
This keeps Bazel version selection anchored by `.bazelversion` while
removing the failing dependency on the archived setup action.
## Verification
- Searched `.github/` to confirm there are no remaining `setup-bazelisk`
references.
- Parsed the updated workflow and action YAML locally with Ruby's
`YAML.load_file`.
## Summary
- Pin Rust git patch dependencies to immutable revisions and make
cargo-deny reject unknown git and registry sources unless explicitly
allowlisted.
- Add checked-in SHA-256 coverage for the current rusty_v8 release
assets, wire those hashes into Bazel, and verify CI override downloads
before use.
- Add rusty_v8 MODULE.bazel update/check tooling plus a Bazel CI guard
so future V8 bumps cannot drift from the checked-in checksum manifest.
- Pin release/lint cargo installs and all external GitHub Actions refs
to immutable inputs.
## Future V8 bump flow
Run these after updating the resolved `v8` crate version and checksum
manifest:
```bash
python3 .github/scripts/rusty_v8_bazel.py update-module-bazel
python3 .github/scripts/rusty_v8_bazel.py check-module-bazel
```
The update command rewrites the matching `rusty_v8_<crate_version>`
`http_file` SHA-256 values in `MODULE.bazel` from
`third_party/v8/rusty_v8_<crate_version>.sha256`. The check command is
also wired into Bazel CI to block drift.
## Notes
- This intentionally excludes RustSec dependency upgrades and
bubblewrap-related changes per request.
- The branch was rebased onto the latest origin/main before opening the
PR.
## Validation
- cargo fetch --locked
- cargo deny check advisories
- cargo deny check
- cargo deny check sources
- python3 .github/scripts/rusty_v8_bazel.py check-module-bazel
- python3 .github/scripts/rusty_v8_bazel.py update-module-bazel
- python3 -m unittest discover -s .github/scripts -p
'test_rusty_v8_bazel.py'
- python3 -m py_compile .github/scripts/rusty_v8_bazel.py
.github/scripts/rusty_v8_module_bazel.py
.github/scripts/test_rusty_v8_bazel.py
- repo-wide GitHub Actions `uses:` audit: all external action refs are
pinned to 40-character SHAs
- yq eval on touched workflows and local actions
- git diff --check
- just bazel-lock-check
## Hash verification
- Confirmed `MODULE.bazel` hashes match
`third_party/v8/rusty_v8_146_4_0.sha256`.
- Confirmed GitHub release asset digests for denoland/rusty_v8
`v146.4.0` and openai/codex `rusty-v8-v146.4.0` match the checked-in
hashes.
- Streamed and SHA-256 hashed all 10 `MODULE.bazel` rusty_v8 asset URLs
locally; every downloaded byte stream matched both `MODULE.bazel` and
the checked-in manifest.
## Pin verification
- Confirmed signing-action pins match the peeled commits for their tag
comments: `sigstore/cosign-installer@v3.7.0`, `azure/login@v2`, and
`azure/trusted-signing-action@v0`.
- Pinned the remaining tag-based action refs in Bazel CI/setup:
`actions/setup-node@v6`, `facebook/install-dotslash@v2`,
`bazelbuild/setup-bazelisk@v3`, and `actions/cache/restore@v5`.
- Normalized all `bazelbuild/setup-bazelisk@v3` refs to the peeled
commit behind the annotated tag.
- Audited Cargo git dependencies: every manifest git dependency uses
`rev` only, every `Cargo.lock` git source has `?rev=<sha>#<same-sha>`,
and `cargo deny check sources` passes with `required-git-spec = "rev"`.
- Shallow-fetched each distinct git dependency repo at its pinned SHA
and verified Git reports each object as a commit.
Replaced ci.bazelrc and v8-ci.bazelrc by custom configs inside the main
.bazelrc file. As a result, github workflows setup is simplified down to
a single '--config=<foo>' flag usage.
Moved the build metadata flags to config=ci.
Added custom tags metadata to help differentiate invocations based on
workflow (bazel vs v8) and os (linux/macos/windows).
Enabled users to override the default values in .bazelrc by using a
user.bazelrc file locally.
Added user.bazelrc to gitignore.
Alternative approach, we use rusty_v8 for all platforms that its
predefined, but lets build from source a musl v8 version with bazel for
x86 and aarch64 only. We would need to release this on github and then
use the release.
