- Make use of `test.MockVariableValue` to override variables for the
duration of the test.
- Don't needlessly call `onGiteaRun`, its only needed when a HTTP server
needs to be called by the code.
- When `onGiteaRun` is used, make use of the passed parameters, such as
the passed `*testing.T` variable and `*url.URL` (this also avoids
needing to serve the routers in the test code again).
- Use `(*url.URL).JoinPath` to craft new URLs.
- Don't override `setting.AppURL` & `setting.Database.LogSQL` when its
does not affect the test.
- Add empty fixture files for `FederatedUser` & `FederationHost` so they
are truncated and do not persist between tests.
Skip a HookEventPullRequestSync event if it has the same CommitSHA as an existing HookEventPullRequest event in the ActionRun table. A HookEventPullRequestSync event must only create an ActionRun if the CommitSHA is different from what it was when the PR was open.
This guards against a race that can happen when the following is done in parallel:
* A commit C is pushed to a repo on branch B
* A pull request with head on branch B
it is then possible that the pull request is created first, successfully. The commit that was just pushed is not known yet but the PR only references the repository and the B branch so it is fine.
A HookEventPullRequest event is sent to the notification queue but not processed immediately.
The commit C is pushed and processed successfully. Since the PR already exists and has a head that matches the branch, the head of the PR is updated with the commit C and a HookEventPullRequestSync event is sent to the notification queue.
The HookEventPullRequest event is processed and since the head of the PR was updated to be commit C, an ActionRun with CommitSHA C is created.
The HookEventPullRequestSync event is then processed and also has a CommitSHA equal to C.
