Related to #22362. I overlooked that there's always `committer.Close()`, like: ```go ctx, committer, err := db.TxContext(db.DefaultContext) if err != nil { return nil } defer committer.Close() // ... if err != nil { return nil } // ... return committer.Commit() ``` So the `Close` of `halfCommitter` should ignore `commit and close`, it's not a rollback. See: [Why `halfCommitter` and `WithTx` should rollback IMMEDIATELY or commit LATER](https://github.com/go-gitea/gitea/pull/22366#issuecomment-1374778612).
