## Why Whenever we return a thread's history (turns and items) over app-server, always return the limited form as specified by the rollout policy `EventPersistenceMode::Limited`, even if the thread was previously started with `EventPersistenceMode::Extended`. We're finding it is quite unscalable to be returning the extended history, so let's apply the same filtering logic of the rollout policy when we load and return the thread's history. ## What Changed - Reuse the rollout persistence policy when reconstructing app-server `ThreadItem` history so only `EventPersistenceMode::Limited` rollout items are replayed into API turns. - Route `thread/read`, `thread/resume`, `thread/fork`, `thread/turns/list`, and rollback responses through the same filtered app-server history projection. - Keep live active turns intact when composing a response for a currently running thread. - Update command execution coverage so persisted extended command events are excluded from returned history for `thread/read`, `thread/fork`, and `thread/turns/list`. ## Test Plan - `cargo test -p codex-app-server limited` - `cargo test -p codex-app-server thread_shell_command` - `cargo test -p codex-app-server thread_read` - `cargo test -p codex-app-server thread_rollback` - `cargo test -p codex-app-server thread_fork` - `cargo test -p codex-app-server-protocol`
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.
