## Why Local integration-heavy `codex-core` CLI tests can time out or be interrupted after spawning `codex exec`. Stopping only the direct child is not enough: `codex exec` can leave grandchildren behind, including `python3`/`python3.12` processes that get reparented to PID 1 and keep running after the test is gone. This PR fixes that failure mode directly for the affected CLI integration tests, without changing production code or reducing local test concurrency. ## What - Run the `cli_stream` `codex exec` subprocesses through a small private wrapper in `core/tests/suite/cli_stream.rs`. - Spawn those subprocesses in their own process group before execution. - Keep `.output()`-style stdout/stderr capture and the existing 30-second timeout behavior. - Own each spawned process with a drop guard that kills the whole process group on success, timeout, panic, or other early return. The switch from `assert_cmd::Command` to `std::process::Command` is only for these subprocess launches; `assert_cmd` does not expose a pre-spawn hook for setting the process group. ## Verification - `just test -p codex-core --test all responses_mode_stream_cli` This is limited to core integration tests; it does not change production `src` code paths.
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
