Subject: git filter-branch should run git gc --auto
Date: Tuesday, January 22, 2008 - 7:43 pm

I just glanced at git-filter-branch.sh (and I must say I was  
incredibly surprised to find out it was a shell script) and it seems  
it never runs git-gc or git-repack. Doesn't that end up with the same  
problems as git-svn sans git-repack when filtering a large number of  
commits? I was just thinking, if I were to git-filter-branch on my  
massive repo (in fact, the same repo that started this thread, with  
over 33000 commits in the upstream svn repo), even if I just do  
something as simple as change the commit msg wont I end up with  
thousands of unreachable objects? I shudder to think how many  
unreachable objects I would have if I pruned the entire dports  
directory off of the tree.

Am I missing something, or does git-filter-branch really not do any  
garbage collection? I tried reading the source, but complex bash  
scripts are almost as bad as perl in terms of readability.
