Atomicity of git-push operation.

Hi,
I have a simple question about "push" operation but I couldn't find an
answer: is git-push (also with --tags flag) atomic ? Especially: if refs changing (during push) is atomic ?
Thanks,
Janek

Yes, its atomic, at the per-ref level.

If you push 3 refs, and one of them updates during the push, the other two will push successfully, but the one that was updated will be rejected.
