This provides a native harness with several advantages over
`pre-commit`:
- Faster when initializing the cache
- Smaller cache sizes: under 43mb compared to over 62mb
- Better integration with `uv` for Python usage
Steps for migrating for existing contributors:
1. Install `prek` following instructions in the updated docs.
2. Replace hooks in an existing checkout with a special flag:
```sh
prek install --overwrite
```
The `--overwrite` flag is what removes the old hooks.
If you used the pre-push variant:
```sh
prek install --hook-type pre-push --overwrite
```
3. Optional cleanups:
```sh
rm -rf ~/.cache/pre-commit # reclaim the old hook-environment cache
pipx uninstall pre-commit # if installed via pipx; or `brew uninstall
pre-commit`
```

Workflows
Hardening
Workflows are hardened using Step Security tool. Findings for the "Harden Runner" steps are available online.
Allowed endpoints
Most jobs only have a few endpoints, but due to tools which do downloads, a few have significantly more. These are:
- clangd_tidy.yaml (Bazel)
- prek.yaml (Bazel, prek)
- nightly_release.yaml (Bazel)
- tests.yaml (Bazel)
When updating one of these, consider updating all of them.
We try to keep allowed-endpoints with one per line. Prettier wants to wrap
them, which we fix this with prettier-ignore.
Testing
We keep around an action-test branch in carbon-lang, which can be used to test
triggers with push: configurations. For example:
on:
push:
branches: [action-test]
