I had an odd request today from a guy who had deleted his GitLab project and his local repos. I had been making backups using:
and sifting through the backups under /var/opt/gitlab/backups/ I extracted the latest tar and under the ./repositories/username directory found some .bundle files for each of his projects.
After some piddling about with git bundle unbundle
error: '/path/to/file/userproject.bundle' does not look like a v2 bundle file
I read that the bundle files are now just tar archives so I extracted the bundle file. e.g.
tar xf userproject.bundle
then noticed the familiar directory layout:
config description HEAD hooks info objects refs
Although I did not have the working files and some of the git commands I ran gave the error:
fatal: This operation must be run in a work tree
So I created some empty directories e.g.
mkdir /tmp1 /tmp2
I then moved the extracted bundle files so that they were contained under /tmp1/.git
I then used a git clone to recreate the files from the bundle into a new directory:
git clone -l /tmp/ /tmp2/
This gave a working copy of the files he needed.
