Earl Warren cfea452aa9 [v11.0/forgejo] fix: do not ignore automerge while a PR is checking for conflicts (#8456)
**Backport: https://codeberg.org/forgejo/forgejo/pulls/8189**

This is a clean cherry-pick codewise. There was a minor conflict to resolve in the tests:

```
Conflicts:
	tests/integration/patch_status_test.go
  the test file did not exist at all in v11 and was added as is with
  one exception: `ObjectFormat: optional.Some("sha256"),` was
  commented out.
```

---

Automerge can be ignored when the following race happens:

* Conflict check is happening on a repository and
  `pr.Status = issues_model.PullRequestStatusChecking` for all open pull
  requests (this happens every time a pull request is merged).
* While the conflict check is ongoing, an event (Forgejo Actions being
  successful for instance) happens and and `StartPRCheckAndAutoMerge*` is called.
* Because `pr.CanAutoMerge()` is false, the pull request is not
  selected and not added to the automerge queue.
* When the conflict check completes and `pr.CanAutoMerge()` becomes
  true, there no longer is a task in the auto merge queue and the
  auto merge does not happen.

This is fixed by adding a task to the auto merge queue when the conflict check for a pull request completes. This is done when the mutx protecting the conflict check task is released to prevent a deadlock when a synchronous queues are used in the following situation:

* the conflict check task finds the pull request is mergeable
* it schedules the auto merge tasks that finds it must be merged
* merging concludes with scheduling a conflict check task

Avoid an extra loop where a conflict check task queues an auto merge task that will schedule a conflict check task if the pull request can be merged. The auto merge row is removed from the database before merging. It would otherwise be removed after the merge commit is received via the git hook which happens asynchronously and can lead to a race.

StartPRCheckAndAutoMerge is modified to re-use HeadCommitID when available, such as when called after a pull request conflict check.

---

A note on tests: they cover the new behavior, i.e. automerge being triggered by a successful conflict check. This is also on the critical paths for every test that involve creating, merging or updating a pull request.

- `tests/integration/git_test.go`
- `tests/integration/actions_commit_status_test.go`
- `tests/integration/api_helper_for_declarative_test.go`
- `tests/integration/patch_status_test.go`
- `tests/integration/pull_merge_test.go`

The [missing fixture file](https://codeberg.org/forgejo/forgejo/pulls/8189/files#diff-b86fdd79108b3ba3cb2e56ffcfd1be2a7b32f46c) for the auto merge table can be verified to be necessary simply by removing it an observing that the integration tests fail.

The [scheduling of the auto merge task](https://codeberg.org/forgejo/forgejo/pulls/8189/files#diff-9489262e93967f6bb2db41837f37c06f4e70d978) in `testPR` can be verified to be required by moving it in the `testPRProtected` function and observing that the tests hang forever because of the deadlock.

## Checklist

Welcome to Forgejo

Hi there! Tired of big platforms playing monopoly? Providing Git hosting for your project, friends, company or community? Forgejo (/for'd͡ʒe.jo/ inspired by forĝejo the Esperanto word for forge) has you covered with its intuitive interface, light and easy hosting and a lot of builtin functionality.

Forgejo was created in 2022 because we think that the project should be owned by an independent community. If you second that, then Forgejo is for you! Our promise: Independent Free/Libre Software forever!

What does Forgejo offer?

If you like any of the following, Forgejo is literally meant for you:

  • Lightweight: Forgejo can easily be hosted on nearly every machine. Running on a Raspberry? Small cloud instance? No problem!
  • Project management: Besides Git hosting, Forgejo offers issues, pull requests, wikis, kanban boards and much more to coordinate with your team.
  • Publishing: Have something to share? Use releases to host your software for download, or use the package registry to publish it for docker, npm and many other package managers.
  • Customizable: Want to change your look? Change some settings? There are many config switches to make Forgejo work exactly like you want.
  • Powerful: Organizations & team permissions, CI integration, Code Search, LDAP, OAuth and much more. If you have advanced needs, Forgejo has you covered.
  • Privacy: From update checker to default settings: Forgejo is built to be privacy first for you and your crew.
  • Federation: (WIP) We are actively working to connect software forges with each other through ActivityPub, and create a collaborative network of personal instances.
