## Why The in-process `app-server-client` tests were still building their configs from the ambient `codex_home` and letting the embedded app server create its own state DB when `state_db` was absent. That matters because in-process startup falls back to `init_state_db_from_config(...)` in that case, so tests can otherwise share persisted state instead of getting isolated fixtures: [`app-server/src/in_process.rs`](a98623511b/codex-rs/app-server/src/in_process.rs (L368-L373)). ## What changed - Give each in-process test client its own temporary `codex_home`. - Initialize the matching state DB from that per-client config and pass it into the client explicitly. - Keep the temp directory alive for the lifetime of the test client through a small `TestClient` wrapper. - Add `tempfile` as a dev dependency for the new harness. The updated setup lives in [`app-server-client/src/lib.rs`](35c1133d45/codex-rs/app-server-client/src/lib.rs (L982-L1055)). ## Testing - Existing `codex-app-server-client` tests continue to exercise the updated in-process client path through the isolated helper.
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.
