## Why Issue #23214 reports `/ps` showing no background terminals while the status line still says it is waiting for a background terminal. The race is in core: `write_stdin` can poll a process that exits before the response returns. The process manager correctly returns `process_id: None`, but the handler still emitted a `TerminalInteraction` event using the requested session id, causing clients to believe a dead process was still being polled. Fixes #23214. ## What changed - Suppress `TerminalInteraction` events for empty `write_stdin` polls once `response.process_id` is `None`. - Continue emitting interactions for non-empty stdin, even if that input causes the process to exit before the response returns. - Extend the unified exec integration test to assert completed empty polls do not emit terminal interactions. ## Verification - `cargo test -p codex-core --test all unified_exec_emits_one_begin_and_one_end_event` - `cargo test -p codex-core --test all unified_exec_emits_terminal_interaction_for_write_stdin` `cargo test -p codex-core` currently aborts in unrelated `agent::control::tests::resume_agent_from_rollout_uses_edge_data_when_descendant_metadata_source_is_stale` with a reproducible stack overflow.
npm i -g @openai/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.
