Summary

When there are multiple files locked by the users in an LFS-enabled repository and someone tries to push a tag into it, it times out. There are no other errors in the logs. But you will still be able to create the tag from the Bitbucket UI.

Environment

Bitbucket server <6.10.11, 7.6.6, 7.12.1

Diagnosis

When the push command is being executed, it doesn't return any other error. It just times out like below after hours.

git push origin tagname
"/usr/bin/git -c core. hooksPath-hooks receive-pack <bitbucket_home>/shared/data/repositories/1" timed out on server.

If we run the same command with debug mode, like below, it runs in an infinite loop for more than 24 hours and fetches the locks.

GIT_TRACE=1 GIT_TRANSFER_TRACE=1 GIT_CURL_VERBOSE=1 git push --tags

git lfs locks command lists more than 100+ locks on files of the repository. 

Cause

The git lfs locks --verify command that runs as part of the git push, runs infinitely when there are more than 100 LFS files with locks in the repository. There is already a bug raised for this.

• BSERV-12803 - Getting issue details... STATUS

So because of this, the push command never completes.

Solution

As a workaround, you can push the tags with the --no-verify parameter. This skips the lock verification.

git push --tags --no-verify

The permanent fix for this problem would be to upgrade to a fixed version listed in the bug report, which are 7.6.6, 6.10.11 and 7.12.1.
