This adds a dummy v8-poc project that in Cargo links against our
prebuilt binaries and the ones provided by rusty_v8 for non musl
platforms. This demonstrates that we can successfully link and use v8 on
all platforms that we want to target.
In bazel things are slightly more complicated. Since the libraries as
published have libc++ linked in already we end up with a lot of double
linked symbols if we try to use them in bazel land. Instead we fall back
to building rusty_v8 and v8 from source (cached of course) on the
platforms we ship to.
There is likely some compatibility drift in the windows bazel builder
that we'll need to reconcile before we can re-enable them. I'm happy to
be on the hook to unwind that.
`CODEX_TEST_REMOTE_ENV` will make `test_codex` start the executor
"remotely" (inside a docker container) turning any integration test into
remote test.
## Why
The argument-comment lint now has a packaged DotSlash artifact from
[#15198](https://github.com/openai/codex/pull/15198), so the normal repo
lint path should use that released payload instead of rebuilding the
lint from source every time.
That keeps `just clippy` and CI aligned with the shipped artifact while
preserving a separate source-build path for people actively hacking on
the lint crate.
The current alpha package also exposed two integration wrinkles that the
repo-side prebuilt wrapper needs to smooth over:
- the bundled Dylint library filename includes the host triple, for
example `@nightly-2025-09-18-aarch64-apple-darwin`, and Dylint derives
`RUSTUP_TOOLCHAIN` from that filename
- on Windows, Dylint's driver path also expects `RUSTUP_HOME` to be
present in the environment
Without those adjustments, the prebuilt CI jobs fail during `cargo
metadata` or driver setup. This change makes the checked-in prebuilt
wrapper normalize the packaged library name to the plain
`nightly-2025-09-18` channel before invoking `cargo-dylint`, and it
teaches both the wrapper and the packaged runner source to infer
`RUSTUP_HOME` from `rustup show home` when the environment does not
already provide it.
After the prebuilt Windows lint job started running successfully, it
also surfaced a handful of existing anonymous literal callsites in
`windows-sandbox-rs`. This PR now annotates those callsites so the new
cross-platform lint job is green on the current tree.
## What Changed
- checked in the current
`tools/argument-comment-lint/argument-comment-lint` DotSlash manifest
- kept `tools/argument-comment-lint/run.sh` as the source-build wrapper
for lint development
- added `tools/argument-comment-lint/run-prebuilt-linter.sh` as the
normal enforcement path, using the checked-in DotSlash package and
bundled `cargo-dylint`
- updated `just clippy` and `just argument-comment-lint` to use the
prebuilt wrapper
- split `.github/workflows/rust-ci.yml` so source-package checks live in
a dedicated `argument_comment_lint_package` job, while the released lint
runs in an `argument_comment_lint_prebuilt` matrix on Linux, macOS, and
Windows
- kept the pinned `nightly-2025-09-18` toolchain install in the prebuilt
CI matrix, since the prebuilt package still relies on rustup-provided
toolchain components
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` to
normalize host-qualified nightly library filenames, keep the `rustup`
shim directory ahead of direct toolchain `cargo` binaries, and export
`RUSTUP_HOME` when needed for Windows Dylint driver setup
- updated `tools/argument-comment-lint/src/bin/argument-comment-lint.rs`
so future published DotSlash artifacts apply the same nightly-filename
normalization and `RUSTUP_HOME` inference internally
- fixed the remaining Windows lint violations in
`codex-rs/windows-sandbox-rs` by adding the required `/*param*/`
comments at the reported callsites
- documented the checked-in DotSlash file, wrapper split, archive
layout, nightly prerequisite, and Windows `RUSTUP_HOME` requirement in
`tools/argument-comment-lint/README.md`
Stacked PR 2/3, based on the stub PR.
Adds the exec RPC implementation and process/event flow in exec-server
only.

### Motivation
- Pinning the action to an immutable commit SHA reduces the risk of
arbitrary code execution in runners with repository access and secrets.
### Description
- Replaced `uses: mlugg/setup-zig@v2` with `uses:
mlugg/setup-zig@d1434d0886 # v2` in three
workflow files.
- Updated the following files: ` .github/workflows/rust-ci.yml`, `
.github/workflows/rust-release.yml`, and `
.github/workflows/shell-tool-mcp.yml` to reference the immutable SHA
while preserving the original `v2` intent in a trailing comment.
### Testing
- No automated tests were run because this is a workflow-only change and
does not affect repository source code, so CI validation will occur on
the next workflow execution.

## Why
Once the repo-local lint exists, `codex-rs` needs to follow the
checked-in convention and CI needs to keep it from drifting. This commit
applies the fallback `/*param*/` style consistently across existing
positional literal call sites without changing those APIs.
The longer-term preference is still to avoid APIs that require comments
by choosing clearer parameter types and call shapes. This PR is
intentionally the mechanical follow-through for the places where the
existing signatures stay in place.
After rebasing onto newer `main`, the rollout also had to cover newly
introduced `tui_app_server` call sites. That made it clear the first cut
of the CI job was too expensive for the common path: it was spending
almost as much time installing `cargo-dylint` and re-testing the lint
crate as a representative test job spends running product tests. The CI
update keeps the full workspace enforcement but trims that extra
overhead from ordinary `codex-rs` PRs.
## What changed
- keep a dedicated `argument_comment_lint` job in `rust-ci`
- mechanically annotate remaining opaque positional literals across
`codex-rs` with exact `/*param*/` comments, including the rebased
`tui_app_server` call sites that now fall under the lint
- keep the checked-in style aligned with the lint policy by using
`/*param*/` and leaving string and char literals uncommented
- cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
registry/git metadata in the lint job
- split changed-path detection so the lint crate's own `cargo test` step
runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
- continue to run the repo wrapper over the `codex-rs` workspace, so
product-code enforcement is unchanged
Most of the code changes in this commit are intentionally mechanical
comment rewrites or insertions driven by the lint itself.
## Verification
- `./tools/argument-comment-lint/run.sh --workspace`
- `cargo test -p codex-tui-app-server -p codex-tui`
- parsed `.github/workflows/rust-ci.yml` locally with PyYAML

## Summary
Stabilize `js_repl` runtime test setup in CI and move tool-facing
`js_repl` behavior coverage into integration tests.
This is a test/CI change only. No production `js_repl` behavior change
is intended.
## Why
- Bazel test sandboxes (especially on macOS) could resolve a different
`node` than the one installed by `actions/setup-node`, which caused
`js_repl` runtime/version failures.
- `js_repl` runtime tests depend on platform-specific
sandbox/test-harness behavior, so they need explicit gating in a
base-stability commit.
- Several tests in the `js_repl` unit test module were actually
black-box/tool-level behavior tests and fit better in the integration
suite.
## Changes
- Add `actions/setup-node` to the Bazel and Rust `Tests` workflows,
using the exact version pinned in the repo’s Node version file.
- In Bazel (non-Windows), pass `CODEX_JS_REPL_NODE_PATH=$(which node)`
into test env so `js_repl` uses the `actions/setup-node` runtime inside
Bazel tests.
- Add a new integration test suite for `js_repl` tool behavior and
register it in the core integration test suite module.
- Move black-box `js_repl` behavior tests into the integration suite
(persistence/TLA, builtin tool invocation, recursive self-call
rejection, `process` isolation, blocked builtin imports).
- Keep white-box manager/kernel tests in the `js_repl` unit test module.
- Gate `js_repl` runtime tests to run only on macOS and only when a
usable Node runtime is available (skip on other platforms / missing Node
in this commit).
## Impact
- Reduces `js_repl` CI failures caused by Node resolution drift in
Bazel.
- Improves test organization by separating tool-facing behavior tests
from white-box manager/kernel tests.
- Keeps the base commit stable while expanding `js_repl` runtime
coverage.

## Summary
- Updates the Linux bubblewrap sandbox args to mount a minimal `/dev`
using `--dev /dev` instead of only binding `/dev/null`. tools needing
entropy (git, crypto libs, etc.) can fail.
- Changed mount order so `--dev /dev` is added before writable-root
`--bind` mounts, preserving writable `/dev/*` submounts like `/dev/shm`
## Why
Fixes sandboxed command failures when reading `/dev/urandom` (and
similar standard device-node access).
Fixes https://github.com/openai/codex/issues/12056
## Summary
CI is broken on main because our CI toolchain is trying to run 1.93.1
while our rust toolchain is locked at 1.93.0. I'm sure it's likely safe
to upgrade, but let's keep things stable for now.
## Testing
- [x] CI should hopefully pass
Problem:
The `aarch64-unknown-linux-musl` release build was failing at link time
with
`/usr/bin/ld: cannot find -lcap` while building binaries that
transitively pull
in `codex-linux-sandbox`.
Why this is the right fix:
`codex-linux-sandbox` compiles vendored bubblewrap and links `libcap`.
In the
musl jobs, we were installing distro `libcap-dev`, which provides
host/glibc
artifacts. That is not a valid source of target-compatible static libcap
for
musl cross-linking, so the fix is to produce a target-compatible libcap
inside
the musl tool bootstrap and point pkg-config at it.
This also closes the CI coverage gap that allowed this to slip through:
the
`rust-ci.yml` matrix did not exercise `aarch64-unknown-linux-musl` in
`release`
mode. Adding that target/profile combination to CI is the right
regression
barrier for this class of failure.
What changed:
- Updated `.github/scripts/install-musl-build-tools.sh` to install
tooling
needed to fetch/build libcap sources (`curl`, `xz-utils`, certs).
- Added deterministic libcap bootstrap in the musl tool root:
- download `libcap-2.75` from kernel.org
- verify SHA256
- build with the target musl compiler (`*-linux-musl-gcc`)
- stage `libcap.a` and headers under the target tool root
- generate a target-scoped `libcap.pc`
- Exported target `PKG_CONFIG_PATH` so builds resolve the staged musl
libcap
instead of host pkg-config/lib paths.
- Updated `.github/workflows/rust-ci.yml` to add a `release` matrix
entry for
`aarch64-unknown-linux-musl` on the ARM runner.
- Updated `.github/workflows/rust-ci.yml` to set
`CARGO_PROFILE_RELEASE_LTO=thin` for `release` matrix entries (and keep
`fat`
for non-release entries), matching the release-build tradeoff already
used in
`rust-release.yml` while reducing CI runtime.
Verification:
- Reproduced the original failure in CI-like containers:
- `aarch64-unknown-linux-musl` failed with `cannot find -lcap`.
- Verified the underlying mismatch by forcing host libcap into the link:
- link then failed with glibc-specific unresolved symbols
(`__isoc23_*`, `__*_chk`), confirming host libcap was unsuitable.
- Verified the fix in CI-like containers after this change:
- `cargo build -p codex-linux-sandbox --target
aarch64-unknown-linux-musl --release` -> pass
- `cargo build -p codex-linux-sandbox --target x86_64-unknown-linux-musl
--release` -> pass
- Triggered `rust-ci` on this branch and confirmed the new job appears:
- `Lint/Build — ubuntu-24.04-arm - aarch64-unknown-linux-musl (release)`
## Why
We want actionable build-hotspot data from CI so we can tune Rust
workflow performance (for example, target coverage, cache behavior, and
job shape) based on actual compile-time bottlenecks.
`cargo` timing reports are lightweight and provide a direct way to
inspect where compilation time is spent.
## What Changed
- Updated `.github/workflows/rust-release.yml` to run `cargo build` with
`--timings` and upload `target/**/cargo-timings/cargo-timing.html`.
- Updated `.github/workflows/rust-release-windows.yml` to run `cargo
build` with `--timings` and upload
`target/**/cargo-timings/cargo-timing.html`.
- Updated `.github/workflows/rust-ci.yml` to:
- run `cargo clippy` with `--timings`
- run `cargo nextest run` with `--timings` (stable-compatible)
- upload `target/**/cargo-timings/cargo-timing.html` artifacts for both
the clippy and nextest jobs
Artifacts are matrix-scoped via artifact names so timings can be
compared per target/profile.
## Verification
- Confirmed the net diff is limited to:
- `.github/workflows/rust-ci.yml`
- `.github/workflows/rust-release.yml`
- `.github/workflows/rust-release-windows.yml`
- Verified timing uploads are added immediately after the corresponding
timed commands in each workflow.
- Confirmed stable Cargo accepts plain `--timings` for the compile phase
(`cargo test --no-run --timings`) and generates
`target/cargo-timings/cargo-timing.html`.
- Ran VS Code diagnostics on modified workflow files; no new diagnostics
were introduced by these changes.
## Summary
This PR removes the temporary `CODEX_BWRAP_ENABLE_FFI` flag and makes
Linux builds always compile vendored bubblewrap support for
`codex-linux-sandbox`.
## Changes
- Removed `CODEX_BWRAP_ENABLE_FFI` gating from
`codex-rs/linux-sandbox/build.rs`.
- Linux builds now fail fast if vendored bubblewrap compilation fails
(instead of warning and continuing).
- Updated fallback/help text in
`codex-rs/linux-sandbox/src/vendored_bwrap.rs` to remove references to
`CODEX_BWRAP_ENABLE_FFI`.
- Removed `CODEX_BWRAP_ENABLE_FFI` env wiring from:
- `.github/workflows/rust-ci.yml`
- `.github/workflows/bazel.yml`
- `.github/workflows/rust-release.yml`

## Summary
This PR introduces a gated Bubblewrap (bwrap) Linux sandbox path. The
curent Linux sandbox path relies on in-process restrictions (including
Landlock). Bubblewrap gives us a more uniform filesystem isolation
model, especially explicit writable roots with the option to make some
directories read-only and granular network controls.
This is behind a feature flag so we can validate behavior safely before
making it the default.
- Added temporary rollout flag:
- `features.use_linux_sandbox_bwrap`
- Preserved existing default path when the flag is off.
- In Bubblewrap mode:
- Added internal retry without /proc when /proc mount is not permitted
by the host/container.
I needed to upgrade bazel one to get gnullvm artifacts and then noticed
monorepo had drifted forward. They should move in lockstep. Also 1.93
already shipped so we can try that instead.
Add a `.sqlite` database to be used to store rollout metatdata (and
later logs)
This PR is phase 1:
* Add the database and the required infrastructure
* Add a backfill of the database
* Persist the newly created rollout both in files and in the DB
* When we need to get metadata or a rollout, consider the `JSONL` as the
source of truth but compare the results with the DB and show any errors
This add a new crate, `codex-network-proxy`, a local network proxy
service used by Codex to enforce fine-grained network policy (domain
allow/deny) and to surface blocked network events for interactive
approvals.
- New crate: `codex-rs/network-proxy/` (`codex-network-proxy` binary +
library)
- Core capabilities:
- HTTP proxy support (including CONNECT tunneling)
- SOCKS5 proxy support (in the later PR)
- policy evaluation (allowed/denied domain lists; denylist wins;
wildcard support)
- small admin API for polling/reload/mode changes
- optional MITM support for HTTPS CONNECT to enforce “limited mode”
method restrictions (later PR)
Will follow up integration with codex in subsequent PRs.
## Testing
- `cd codex-rs && cargo build -p codex-network-proxy`
- `cd codex-rs && cargo run -p codex-network-proxy -- proxy`

Changes in these release are <strong>fully backward
compatible</strong>.</p>
<p><strong>We are deprecating some versions of this action</strong>. We
recommend upgrading to version <code>v4</code> or <code>v3</code> as
soon as possible before <strong>February 1st, 2025.</strong> (Upgrade
instructions below).</p>
<p>If you are using pinned SHAs, please use the SHAs of versions
<code>v4.2.0</code> or <code>v3.4.0</code></p>
<p>If you do not upgrade, all workflow runs using any of the deprecated
<a href="https://github.com/actions/cache">actions/cache</a> will
fail.</p>
<p>Upgrading to the recommended versions will not break your
workflows.</p>

When I originally introduced `accept_elicitation_for_prompt_rule()` in
https://github.com/openai/codex/pull/7617, it worked for me locally
because I had run `codex-rs/exec-server/tests/suite/bash` once myself,
which had the side-effect of installing the corresponding DotSlash
artifact.
In CI, I added explicit logic to do this as part of
`.github/workflows/rust-ci.yml`, which meant the test also passed in CI,
but this logic should have been done as part of the test so that it
would work locally for devs who had not installed the DotSlash artifact
for `codex-rs/exec-server/tests/suite/bash` before. This PR updates the
test to do this (and deletes the setup logic from `rust-ci.yml`),
creating a new `DOTSLASH_CACHE` in a temp directory so that this is
handled independently for each test.
While here, also added a check to ensure that the `codex` binary has
been built prior to running the test, as we have to ensure it is
symlinked as `codex-linux-sandbox` on Linux in order for the integration
test to work on that platform.
This PR introduces integration tests that run
[codex-shell-tool-mcp](https://www.npmjs.com/package/@openai/codex-shell-tool-mcp)
as a user would. Note that this requires running our fork of Bash, so we
introduce a [DotSlash](https://dotslash-cli.com/) file for `bash` so
that we can run the integration tests on multiple platforms without
having to check the binaries into the repository. (As noted in the
DotSlash file, it is slightly more heavyweight than necessary, which may
be worth addressing as disk space in CI is limited:
https://github.com/openai/codex/pull/7678.)
To start, this PR adds two tests:
- `list_tools()` makes the `list_tools` request to the MCP server and
verifies we get the expected response
- `accept_elicitation_for_prompt_rule()` defines a `prefix_rule()` with
`decision="prompt"` and verifies the elicitation flow works as expected
Though the `accept_elicitation_for_prompt_rule()` test **only works on
Linux**, as this PR reveals that there are currently issues when running
the Bash fork in a read-only sandbox on Linux. This will have to be
fixed in a follow-up PR.
Incidentally, getting this test run to correctly on macOS also requires
a recent fix we made to `brew` that hasn't hit a mainline release yet,
so getting CI green in this PR required
https://github.com/openai/codex/pull/7680.
When I put up https://github.com/openai/codex/pull/7617 for review,
initially I started seeing failures on the `ubuntu-24.04` runner used
for Rust test runs for the `x86_64-unknown-linux-gnu` architecture. Chat
suggested a number of things that could be removed to save space, which
seems to help.

## Summary
musl 1.2.5 includes [several fixes to DNS over
TCP](https://www.openwall.com/lists/musl/2024/03/01/2), which appears to
be the root cause of #6116.
This approach is a bit janky, but according to codex:
> On the Ubuntu 24.04 runners we use, apt-cache policy musl-tools shows
only the distro build (1.2.4-2ubuntu2)"
We should build with this version and confirm.
## Testing
- [ ] TODO: test and see if this fixes Azure issues
As a follow-up to https://github.com/openai/codex/pull/3439, this adds a
CI job to ensure the codegen script has to be updated in order to change
`codex-rs/mcp-types/src/lib.rs`.
I started looking at https://nexte.st/ because I was interested in a
test harness that lets a test dynamically declare itself "skipped,"
which would be a nice alternative to this pattern:
4c46490e53/codex-rs/core/tests/suite/cli_stream.rs (L22-L27)
ChatGPT pointed me at https://nexte.st/, which also claims to be "up to
3x as fast as cargo test." Locally, in `codex-rs`, I see
- `cargo nextest run` finishes in 19s
- `cargo test` finishes in 37s
Though looking at CI, the wins are quite as big, presumably because my
laptop has more cores than our GitHub runners (which is a separate
issue...). Comparing the [CI jobs from this
PR](https://github.com/openai/codex/actions/runs/17561325162/job/49878216246?pr=3323)
with that of a [recent open
PR](https://github.com/openai/codex/actions/runs/17561066581/job/49877342753?pr=3321):
| | `cargo test` | `cargo nextest` |
| ----------------------------------------------- | ------------ |
--------------- |
| `macos-14 - aarch64-apple-darwin` | 2m16s | 1m51s |
| `macos-14 - aarch64-apple-darwin` | 5m04s | 3m44s |
| `ubuntu-24.04 - x86_64-unknown-linux-musl` | 2m02s | 1m56s |
| `ubuntu-24.04-arm - aarch64-unknown-linux-musl` | 2m01s | 1m35s |
| `windows-latest - x86_64-pc-windows-msvc` | 3m07s | 2m53s |
| `windows-11-arm - aarch64-pc-windows-msvc` | 3m10s | 2m45s |
I thought that, to start, we would only make this change in CI before
declaring it the "official" way for the team to run the test suite.
Though unfortunately, I do not believe that `cargo nextest` _actually_
supports a dynamic skip feature, so I guess I'll have to keep looking?
Some related discussions:
- https://internals.rust-lang.org/t/pre-rfc-skippable-tests/14611
- https://internals.rust-lang.org/t/skippable-tests/21260
This is in support of https://github.com/openai/codex/issues/2979.
Once we have a release out, we can update the npm module and the VS Code
extension to take advantage of this.
Today we had a breakage in the release build that went unnoticed by CI.
Here is what happened:
- https://github.com/openai/codex/pull/2242 originally added some logic
to do release builds to prevent this from happening
- https://github.com/openai/codex/pull/2276 undid that change to try to
speed things up by removing the step to build all the individual crates
in release mode, assuming the `cargo check` call was sufficient
coverage, which it would have been, had it specified `--profile`
This PR adds `--profile` to the `cargo check` step so we should get the
desired coverage from our build matrix.
Indeed, enabling this in our CI uncovered a warning that is only present
in release mode that was going unnoticed.
Codex created this PR from the following prompt:
> upgrade this entire repo to Rust 1.89. Note that this requires
updating codex-rs/rust-toolchain.toml as well as the workflows in
.github/. Make sure that things are "clippy clean" as this change will
likely uncover new Clippy errors. `just fmt` and `cargo clippy --tests`
are sufficient to check for correctness
Note this modifies a lot of lines because it folds nested `if`
statements using `&&`.
