We need to file a bug to gerrit team regarding the first error, I'm going to fix the second error.

https://buganizer.corp.google.com/issues/69461507

Assign to nxia@ to fix the git push error, gerrit team has disabled the private key check for us

I think we don't change our current behavior of git push, but we fix the 'git log' failure which was threw after the 'git push' failure.

validation_pool: check git log diff between local HEAD and remote_ref

When the local repository doesn't contain the branch ('master') to push
to, running git log diff on revisions will error.
