Git push failure

Question

I am trying to cleanup huge git repo history using BFG cleaner tool.

For same i first create a mirror of git repo to be cleaned.

git clone --mirror git://example.com/some-big-repo.git

I run few commands to do the clean and later when I am finished I try to push my changes.

git push

This fails with below stack trace

error: failed to push some refs to 'ssh://git@example.com/some-big-repo.git'

To fix above issue i tried to increase the stash hook buffer capacity as I thought that might be the failure reason.

Go to stash-config.properties
hook.callback.buffer.capacity=15728640

But i still continue to get the push error.

Please advise.

You have to deal with (decline or merge) the open pull requests in your repository.

I have faced with same problem (given in detailed below) during mirroring a git repository on Bitbucket server to an another server.

$ git push -f NEW-REMOTE --mirror

remote: Rejected refs:
remote: refs/pull-requests/2/from

Actually the error message is not clear or informative or directive very much but it shows that something related to refs is wrong or missing in your source repository. In my problem, there was open pull requests in the source repository which I was mirroring to another server. I declined the pull requests (you might merge it regarding the pull request details) and then mirroring operation is accomplished without any error.

In order to see whether there is an open pull requests in your source repository, you can look at this link below:

The reason I was facing above issue is as I mirror clone the repository which also clones the pull requests. remote: Rejected refs:remote: refs/pull-requests/190/fromremote: refs/pull-requests/247/fromremote: refs/pull-requests/247/mergeTo ssh://git@example.com/some-big-repo.gitI had to get rid of the pull request(by either getting them merged or declined) and then do the mirror clone again Everything worked fine this time.
