## Summary - avoid generating host proxy bridge Unix socket paths that exceed Linux's `sockaddr_un.sun_path` limit - fall back from a long `$CODEX_HOME/tmp` path to the system temp directory, then `/tmp` - add focused unit coverage for short and overlong parent paths ## Root cause With a sufficiently long `CODEX_HOME`, the generated `proxy-route-*.sock` path exceeds Linux's 107-byte pathname limit. The host bridge child exits before writing its readiness byte, so the parent reports the indirect error `failed to prepare host proxy routing bridge: failed to fill whole buffer`. ## Validation - reproduced the original error with a long `CODEX_HOME` using `codex-cli 0.138.0-alpha.4` - `cargo clippy -p codex-linux-sandbox --all-targets` - `just fix -p codex-linux-sandbox` - `just fmt` The Linux-only unit test could not execute locally: the arm64 Docker build was repeatedly OOM-killed by `rustc` while compiling an unrelated `codex-app-server-protocol` dependency, before reaching the test. --------- Co-authored-by: Codex <noreply@openai.com>
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.
