Introduced in GitLab 8.4.
GitLab automatically runs
git gc and
git repack on repositories after Git pushes. If needed you can change how often this happens, or to turn it off, go to Admin area > Settings (
The housekeeping function will run a
gc depending on the "Automatic Git repository housekeeping" settings configured in Admin area > Settings
For example in the following scenario a
git repack -d will be executed:
pushes_since_gc value is 50 a
repack -A -d --pack-kept-objects will run, similarly when the
pushes_since_gc value is 200 a
git gc will be run.
git gc (man page) runs a number of housekeeping tasks, such as compressing filerevisions (to reduce disk space and increase performance) and removing unreachable objects which may have been created from prior invocations of
git repack (man page) re-organize existing packs into a single, more efficient pack.
You can find this option under your [Project] > Edit Project.
