Jon Ross-Perkins 24c173b10f Try using same_pkg_direct_rdeps for clang-tidy action (#5144)
This is trying to reduce how much we run tidy over due to poor
performance of tidy.

It's opening the door for issues where a header file is modified in a
way that introduces tidy issues in a different target. However, that's
not the typical tidy issue we see.

There may also be a risk where a source file indirectly becomes a source
file for a target in a way that `same_pkg_direct_rdeps` doesn't return,
but I'm not sure that's applicable for how we use targets.

An example of this locating a diagnostic error can be found in the "Add
tidy issue" commit's run (which I cancelled before it finished running,
but note the error):

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:

  • pre_commit.yaml (Bazel, pre-commit)
  • 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]
