Description

Steps to reproduce

1. Prepare repo on bitbucket with some commits/code
2. Migrate repo from Bitbucket (with mirroring enabled) via https clone url
3. After migration ends look at the migrated repository page. It will look like there is no code in repo
4. Go into repo dir on file system and check via "git log" command that this repo has some commits (and code too)

In DB i see that row with imported repository (in "repository" table) has value "is_empty = true". I think that this behavior caused by change in isempty method 913d6f3

Migration was fine on version 1.15.8, today we update our instance and this new behavior was appered

Example of old code (before commit 913d6f3)
[root@ci-gitea .git]# git rev-list --all --count --max-count=1
1
[root@ci-gitea .git]# git show-ref --head ^HEAD$
[root@ci-gitea .git]

Current workaround - update migrated repos with "is_empty = true" to "is_empty = false", after that repo content is displayed properly. Any cron jobs wasn't help, Add to reindex queue wasn't help too

This problem is caused by a very old git client. The problem is git show-ref --head ^HEAD$ is not supported by old git client.

Use 2.x won't have any problem.

You are right, I missed it - will try to update. Thank you

[IT-AlexKor]

Works great. Thanky you for support and sorry for late update
