## Why `#[large_stack_test]` made the `apply_patch_cli` tests pass by giving them more stack, but it did not address why those tests needed the extra stack in the first place. The real problem is the async state built by the `apply_patch_cli` harness path. Those tests await three helper boundaries directly: harness construction, turn submission, and apply-patch output collection. If those helpers inline their full child futures, the test future grows to include the whole harness startup and request/response path. This change replaces the workaround from #12768 with the same basic approach used in #13429, but keeps the fix narrower: only the helper boundaries awaited directly by `apply_patch_cli` stay boxed. ## What Changed - removed `#[large_stack_test]` from `core/tests/suite/apply_patch_cli.rs` - restored ordinary `#[tokio::test(flavor = "multi_thread", worker_threads = 2)]` annotations in that suite - deleted the now-unused `codex-test-macros` crate and removed its workspace wiring - boxed only the three helper boundaries that the suite awaits directly: - `apply_patch_harness_with(...)` - `TestCodexHarness::submit(...)` - `TestCodexHarness::apply_patch_output(...)` - added comments at those boxed boundaries explaining why they remain boxed ## Testing - `cargo test -p codex-core --test all suite::apply_patch_cli -- --nocapture` ## References - #12768 - #13429
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.
