## What is flaky `codex-rs/app-server/tests/suite/fuzzy_file_search.rs` intermittently loses the expected `fuzzyFileSearch/sessionUpdated` and `fuzzyFileSearch/sessionCompleted` notifications when multiple fuzzy-search sessions are active and CI delivers notifications out of order. ## Why it was flaky The wait helpers were keyed only by JSON-RPC method name. - `wait_for_session_updated` consumed the next `fuzzyFileSearch/sessionUpdated` notification even when it belonged to a different search session. - `wait_for_session_completed` did the same for `fuzzyFileSearch/sessionCompleted`. - Once an unmatched notification was read, it was dropped permanently instead of buffered. - That meant a valid completion for the target search could arrive slightly early, be consumed by the wrong waiter, and disappear before the test started waiting for it. The result depended on notification ordering and runner scheduling instead of on the actual product behavior. ## How this PR fixes it - Add a buffered notification reader in `codex-rs/app-server/tests/common/mcp_process.rs`. - Match fuzzy-search notifications on the identifying payload fields instead of matching only on method name. - Preserve unmatched notifications in the in-process queue so later waiters can still consume them. - Include pending notification methods in timeout failures to make future diagnosis concrete. ## Why this fix fixes the flakiness The test now behaves like a real consumer of an out-of-order event stream: notifications for other sessions stay buffered until the correct waiter asks for them. Reordering no longer loses the target event, so the test result is determined by whether the server emitted the right notifications, not by which one happened to be read first.

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.
