## Why A Mac Bazel CI run saw `remote_notifications_arrive_over_websocket` fail during shutdown with `remote app-server shutdown channel is closed` (https://app.buildbuddy.io/invocation/9dac05d6-ae20-40f9-b627-fca6e91cf127). The remote websocket worker can legitimately finish while `shutdown()` is waiting for the shutdown acknowledgement: after the test server sends a notification and exits, the worker may deliver the required disconnect event, observe that the caller has dropped the event receiver, and exit before it sends the shutdown one-shot. That state is already terminal cleanup, not a failed shutdown, so callers should not see a `BrokenPipe` from the acknowledgement channel. ## What Changed - Treat a closed remote shutdown acknowledgement as an already-exited worker while still propagating websocket close errors when the worker returns them. - Added a deterministic regression test for the interleaving where the shutdown command is received and the worker exits before replying. ## Verification - `cargo test -p codex-app-server-client` - New test: `remote::tests::shutdown_tolerates_worker_exit_after_command_is_queued`
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.
