git push --mirror with gerrit

[ffa]

git push --mirror does not work for me. I get two errors. One error is for branches "can not create new references". The other is for tags which initially pushes successfully, but then failed with "failed to lock". If I grant all privileges to refs/*, it pushes, but when I clone, nothing shows. The GUI shows nothing under the branches section of the project. And, It doesn't seem to push the branches under refs/heads/. Is everyone using repo to do stuff like this? Because, all of my searches seem to return discussions about using repo to mirror or initialize the mirror.

Seeing the terminal output would help.

I've seen this message too, and I think it's caused by a) the tag
already exists or b) there are no branches pointing to the tag (making
the tag invisible to clients).

Instead of using --mirror, push a single branch and see what happens.

git push ssh://user@host:29418/path/to/git mybranch:refs/heads/mybranch

(Or origin/mybranch:refs/heads/mybranch or whatever it is that you're pushing.)

Is the push reported as successful? Does it show up on the Branches
page? Is there a change in the refs in the underlying git on the
server (assuming you have server access)?

If you're dealing with multiple gits managed by Repo, it's natural to
use Repo (specifically the "forall" subcommand) to automate operations
for all gits. Apart from that, Repo has nothing to do with the pushes.
It's just a wrapper tool to ease the pain of dealing with hundreds of
gits.

Here is output from trying to mirror the gerrit repo.

Instead of using --mirror, push a single branch and see what happens.

git push ssh://user@host:29418/path/to/git mybranch:refs/heads/mybranch

(Or origin/mybranch:refs/heads/mybranch or whatever it is that you're pushing.)

Is the push reported as successful? Does it show up on the Branches
page? Is there a change in the refs in the underlying git on the
server (assuming you have server access)?

This following tests are with permissions for refs/heads/*.

The below command fails.

Also, I have only fetched the branches I am mirroring or pushing.

for example:
git fetch upstream
git push --mirror origin
