Re: [ANNOUNCE] repo.or.cz now supports "project forks"

Dear diary, on Tue, Oct 24, 2006 at 06:52:01AM CEST, I got a letter
where Petr Baudis <pasky@suse.cz> said that...

  BTW, someone asked me why not stuff it in branches in the same
directory, and it's a valid question. It's been my original plan (and I
might still implement it sometimes since it makes sense in some
situations) but after I formulated it at #git I realized that it's
really a no-go for the general case.

  The plan was to have "personal mob-branches", mob/$login/*. Anyone can
make any branch in the mob/$login namespace in any project. But I didn't
feel like implementing it for now, because:

	* git-clone / cg-clone -a would clone even the potential gazillion
	  of mob/$login branches any weirdo can create

	* You get own heads namespace but own tags namespace would be
	  I think more inconvenient since you tend to refere to tags
	  much more often than to branches (if you even have one than
	  one branch) and having to write mob/mynameisverylong/xyzzy-1.2.3.4
	  is, er...

	* One of the big points of forks is that you can fork even
	  mirrored projects. If you start to create branches in mirrored
	  projects, you can get into very ugly problems when by a chance
	  the mirrored project gets such a branch as well

  One sad consequence is that graphiclog does not include the forked
projects, OTOH perhaps its view would be way too cluttered if it did,
and I want to optimize for a large number of forks. So it would be more
sensible if someone (hint, hint) patched git-browser in a way so that
forked projects include the "forkee"'s refs in the view as well, in
addition to own refs. And perhaps a more general notion for this in the
Git world would be interesting.
