Hi, I'm experiencing a strange behavior of automatic git gc which corrupts a local repository. Git version 2.2.2 on Mac OS X 10.10.1.
I'm using git p4 for synchronization with perforce. Sometimes after 'git p4 rebase' git starts a garbage collection. When gc finishes a local repository contains no pack files only loose objects, so I have to re-import repository from perforce. It also doesn't contain a temporary pack git gc was creating. Command line history looks like this: > git p4 rebase Performing incremental import into refs/remotes/p4/master git branch Depot paths: //XXX/YYY/ Import destination: refs/remotes/p4/master Importing revision 352157 (100%) Rebasing the current branch onto remotes/p4/master First, rewinding head to replay your work on top of it... Fast-forwarded master to remotes/p4/master. Auto packing the repository in background for optimum performance. See "git help gc" for manual housekeeping. > ps aux | grep git nd 14335 95.0 1.4 4643292 114788 ?? R 8:52PM 0:05.79 git pack-objects --keep-true-parents --honor-pack-keep --non-empty --all --reflog --indexed-objects --unpack-unreachable=2.weeks.ago --local --delta-base-offset /path/to/repo/.git/objects/pack/.tmp-14333-pack nd 14333 0.0 0.0 2452420 920 ??

One more thing about my setup: since git p4 promotes a use of a linear history I use a separate repository for another branch in perforce. In order to be able to cherry-pick between repositories I added this another repo objects dir as an alternate and also added a ref which is a symbolic link to a branch in another repo (so I don't have to do any fetches). How do I troubleshoot the problem? Is there any way to enable a some kind of logging for automatic git gc? Can use of alternates or symbolic links in refs cause such a behavior? -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
