JGit/EGit now supports gc? [message #934072]

Today I noticed an operation I hadn't seen before on the right-click menu of entries in the Git Repositories view: Collect Garbage.

I take it this is the JGit equivalent of 'git gc'? That's certainly handy. Does it also prune?

That's right, that's really "git gc". It's the first version of it in JGit. Not all the semantics of git gc are there. But currently it does a pack-refs, repack and prune. Specifically for prune JGit also has learned to understand config param gc.pruneExpire. Since it is the first version of GC in JGit and since it is a potentially dangerous operation we are not advertizing it heavily to EGit users. We want to get more experiences with it before we put it to a more prominent place or support automatic garbage collection.
And yes, there are also missing features: we don't do reflog_expire and rerere_gc currently. We are also not moving objects from packfiles to the object directory when they get unreferenced. But the basic functionality is working.
