PHP LocalFile::getArchiveRel方法代码示例

 /**
  * Run the transaction, except the cleanup batch.
  * The cleanup batch should be run in a separate transaction, because it locks different
  * rows and there's no need to keep the image row locked while it's acquiring those locks
  * The caller may have its own transaction open.
  * So we save the batch and let the caller call cleanup()
  * @return FileRepoStatus
