## Why `thread/resume` responses for already-running threads can be reported as `Idle` even while a turn is still in progress. This is caused by a timing window where the runtime watch state has not yet observed the running-thread transition, so API clients can receive stale status information at resume time. Possibly related: https://github.com/openai/codex/pull/11786 ## What - Add a shared status normalization helper, `resolve_thread_status`, in `codex-rs/app-server/src/thread_status.rs` that resolves `Idle`/`NotLoaded` to `Active { active_flags: [] }` when an in-progress turn is known. - Reuse this helper across thread response paths in `codex-rs/app-server/src/codex_message_processor.rs` (including `thread/start`, `thread/unarchive`, `thread/read`, `thread/resume`, `thread/fork`, and review/thread-started notification responses). - In `handle_pending_thread_resume_request`, use both the in-memory `active_turn_snapshot` and the resumed rollout turns to decide whether a turn is in progress before resolving thread status for the response. - Extend `thread_status` tests to validate the new status-resolution behavior directly. ## Verification - `cargo test -p codex-app-server suite::v2::thread_resume::thread_resume_rejoins_running_thread_even_with_override_mismatch`
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.
