## Why Interrupted `shell_command` calls can race with the outer tool-dispatch cancellation path. When that happens, the runtime future may be dropped before the spawned process gets a chance to run `SIGTERM` cleanup. For bwrapd-backed Linux sandbox commands, that can leave synthetic protected-path mount bookkeeping such as `.git/.codex` registrations under `/tmp` behind after a TUI interruption. The relevant cancellation points are the outer dispatch race in [`core/src/tools/parallel.rs`](https://github.com/openai/codex/blob/bd184ba84703cc924921ed883f0cf17d3dba60ff/codex-rs/core/src/tools/parallel.rs#L91-L132) and the process shutdown logic in [`core/src/exec.rs`](https://github.com/openai/codex/blob/bd184ba84703cc924921ed883f0cf17d3dba60ff/codex-rs/core/src/exec.rs#L1367-L1393). ## What changed - Keep `shell_command` dispatch alive long enough for the runtime to finish cancellation cleanup instead of immediately returning the synthetic aborted response. - Fold shell-turn cancellation into the existing `ExecExpiration` path in [`core/src/tools/runtimes/shell.rs`](https://github.com/openai/codex/blob/bd184ba84703cc924921ed883f0cf17d3dba60ff/codex-rs/core/src/tools/runtimes/shell.rs#L267-L274), so cancellation and timeout behavior stay centralized. - On cancellation, send `SIGTERM` first, wait briefly for cleanup to run, then hard-kill any remaining descendants in the original process group. - Treat `ESRCH` as an already-gone process-group cleanup case in `codex-utils-pty`, which keeps best-effort teardown from surfacing a stale-process race as an error. ## Verification - `cargo test -p codex-core cancellation` - Added regression coverage for: - `shell_tool_cancellation_waits_for_runtime_cleanup` - `process_exec_tool_call_cancellation_allows_sigterm_cleanup`

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
