We just need to call\n that in the end of the receive code.\n\n line 236 calls WalkRemoteObjectDatabase.writeInfoPacks() to\n update the GIT_DIR/objects/info/packs file. This needs to\n be abstracted out so we can more easily reuse it.\n\n> > Arguably it should. but it doesn't. Then there is a question as to what\n> > format those hooks should be.

I'd like to get a reasonable binding to\nBSF for JGit, but its more of a wish than a real need for me, so\nI just don't bother. I think many people who want to script Git\nfrom Python would be reasonably happy with executing that script\nthrough Jython if there was a decent binding.\n \n-- \nShawn.\n"}]}
