Description

REPO_INDEXER won't index mirrored repository after sync

func (r *indexerNotifier) NotifySyncPushCommits(pusher *models.User, repo *models.Repository, opts *repository.PushUpdateOptions, commits *repository.PushCommits) {
	if setting.Indexer.RepoIndexerEnabled && opts.RefFullName == git.BranchPrefix+repo.DefaultBranch {
		code_indexer.UpdateRepoIndexer(repo)
	}
	if err := stats_indexer.UpdateRepoIndexer(repo); err != nil {
		log.Error("stats_indexer.UpdateRepoIndexer(%d) failed: %v", repo.ID, err)
	}
}

It might be that you don't have a default branch set?

Go to the Repository Settings and change/re-set the default branch.

I tired resetting the default branch but it doesn't work.

Also I didn't see any error in the logs. I am sure that I have RepoIndexerEnabled, as the code search works for plain repos instead of the mirrored ones.

Tired on 1.13.7 with many different mirrored repos, but the problem persists.
Also I tried deleting repos.bleve to rebuild the index. The REPO_INDEXER will properly index the current default branch of the mirrored repo, but it's not going to index new commits after sync

@zeripath Same on v1.14.1

Same with v1.14.2

Just to chime in that I am also noticing this issue on v1.18.5. Default branch is set as well.

I patched the original snippet of code to log out the test variables, in the following, and it seems that opts.RefFullName is not the same between push and sync pull.

func (r *indexerNotifier) NotifyPushCommits(pusher *user_model.User, repo *repo_model.Repository, opts *repository.PushUpdateOptions, commits *repository.PushCommits) {
	log.Info("stats_indexer.NotifyPushCommits(%d) RefFullName: %s, BranchPrefix: %s, DefaultBranch: %s", repo.ID, opts.RefFullName, git.BranchPrefix, repo.DefaultBranch)

	if setting.Indexer.RepoIndexerEnabled && opts.RefFullName == git.BranchPrefix+repo.DefaultBranch {
		code_indexer.UpdateRepoIndexer(repo)
	}
	if err := stats_indexer.UpdateRepoIndexer(repo); err != nil {
		log.Error("stats_indexer.UpdateRepoIndexer(%d) failed: %v", repo.ID, err)
	}
}

func (r *indexerNotifier) NotifySyncPushCommits(pusher *user_model.User, repo *repo_model.Repository, opts *repository.PushUpdateOptions, commits *repository.PushCommits) {
	log.Info("stats_indexer.NotifySyncPushCommits(%d) RefFullName: %s, BranchPrefix: %s, DefaultBranch: %s", repo.ID, opts.RefFullName, git.BranchPrefix, repo.DefaultBranch)

	if setting.Indexer.RepoIndexerEnabled && opts.RefFullName == git.BranchPrefix+repo.DefaultBranch {
		code_indexer.UpdateRepoIndexer(repo)
	}
	if err := stats_indexer.UpdateRepoIndexer(repo); err != nil {
		log.Error("stats_indexer.UpdateRepoIndexer(%d) failed: %v", repo.ID, err)
	}
}

When pushing,

2023/02/22 11:07:06 ...n/indexer/indexer.go:128:NotifyPushCommits() [I] [63f5f75a] stats_indexer.NotifyPushCommits(200) RefFullName: refs/heads/main, BranchPrefix: refs/heads/, DefaultBranch: main

When sync pulling,

2023/02/22 11:06:50 ...n/indexer/indexer.go:139:NotifySyncPushCommits() [I] [63f5f749-17] stats_indexer.NotifySyncPushCommits(199) RefFullName: main, BranchPrefix: refs/heads/, DefaultBranch: main

So clearly the comparison of setting.Indexer.RepoIndexerEnabled && opts.RefFullName == git.BranchPrefix+repo.DefaultBranch might need to be modified.
