Pull the hook logic into a reusable githook library package so tailscale/corp can share it via a thin wrapper main instead of keeping a forked copy in sync. The install flow also changes: a wrapper scripts now build the binary and reinstall the git hooks. Pulling new shared code no longer requires re-running the installer.

# git_hook
|
|
|
|
Tailscale's git hooks.
|
|
|
|
The shared logic lives in the `githook/` package and is also imported by
|
|
`tailscale/corp`.
|
|
|
|
## Install
|
|
|
|
From the repo root:
|
|
|
|
./tool/go run ./misc/install-git-hooks.go
|
|
|
|
The script auto-updates in the future.
|
|
|
|
|
|
## Adding your own hooks
|
|
|
|
Create an executable `.git/hooks/<hook-name>.local` to chain a custom
|
|
script after a built-in hook. For example, put a custom check in
|
|
`.git/hooks/pre-commit.local` and `chmod +x` it. The local hook runs
|
|
only if the built-in hook succeeds; failure aborts the git operation.
|
|
|
|
|
|
## Changing the shared code
|
|
|
|
When you change anything under `githook/` or `launcher.sh`, bump
|
|
`HOOK_VERSION` in the same commit so every dev auto rebuilds on their next
|
|
git operation.
|
|
|
|
Because `tailscale/corp` imports `githook/`, also plan the downstream
|
|
update: after landing here, bump corp's `tailscale.com` dependency and
|
|
bump corp's own `misc/git_hook/HOOK_VERSION` on a separate commit. Both are
|
|
required.
