Picking up this slightly old thread.
Joe, does that mean (I hope) that we won't witness _two_ separate
transitions (e.g. hg to self-hosted git, then self-hosted git to hosted
git) ? Or is that still on the card somehow?
Every time we change repository (as has happened twice already with the
consolidation effort first, and the creation of the jdk/jdk repo later),
there is a lot of cost for all the infrastructure that surrounds the
JDK. Being the maintainer of several automated build and test and merge
systems for the various Amber, Valhalla and Panama projects make me feel
this pain acutely :-) (and I know I'm not alone in this)
So, while I'm not opposed to a move from hg to git (I find the two to be
mark over git's extensibility - as I had fun a couple of times writing
python plugins for mercurial), I'll just plead for attempting to
minimize disruption (and hence number of moves) as much as possible.
