## Why PR #18431 exposed a Bazel clippy failure in the app-server unit-test target across Linux, macOS, and Windows. The failing lint was `clippy::await_holding_invalid_type`: two tracing tests serialized access to global tracing state by holding a `tokio::sync::MutexGuard` across awaited test work. That serialization is still needed because the tests share process-global tracing setup and exporter state, but it should not require holding an async mutex guard through the whole test body. ## What changed - Replaced the bespoke async `tracing_test_guard` helper with `serial_test` on the two tracing tests that need global tracing serialization. - Removed the `#[expect(clippy::await_holding_invalid_type)]` annotations and the lock guard callsites that Bazel clippy rejected. ## Validation - `cargo test -p codex-app-server jsonrpc_span` - `just fix -p codex-app-server` - `git diff --check` I also attempted the exact failing Bazel clippy target locally with BuildBuddy disabled: `bazel --noexperimental_remote_repo_contents_cache build --config=clippy --bes_backend= --remote_cache= --experimental_remote_downloader= -- //codex-rs/app-server:app-server-unit-tests-bin`. That run did not reach clippy because Bazel timed out downloading `libcap-2.27.tar.gz` from `kernel.org`.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
