## Why The app-server daemon work needs two app-server behaviors to be safe when lifecycle management is driven by a helper process: - a readiness probe must not become the process-wide client identity just because it connects first - a graceful reload signal needs to keep draining active turns even if it is delivered more than once ## What changed - Treat `codex_app_server_daemon` initialization as a probe-only client for process-global originator and user-agent suffix state. - Distinguish forceable shutdown signals from graceful-only ones, and treat Unix `SIGHUP` as graceful-only while leaving `SIGTERM` and Ctrl-C forceable. - Add regression coverage for daemon probe initialization and repeated `SIGHUP` delivery while a turn is still running. ## Testing - `cargo test -p codex-app-server` - The new daemon-probe and repeated-`SIGHUP` coverage passed. - The run still failed in the existing `suite::conversation_summary::get_conversation_summary_by_relative_rollout_path_resolves_from_codex_home` and `suite::conversation_summary::get_conversation_summary_by_thread_id_reads_rollout` tests because their initialize handshake timed out. - `cargo test -p codex-app-server --test all suite::conversation_summary::` - Reproduced the same two existing initialize-timeout failures in isolation.
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.
