Moving Away From CVS: A Vote

[Charlie Powell]

Although I don't have much experience with either Hg or Bzr, it appears to me that bzr has more support backing its development and use; Hg just has Mozilla corp. In addition, pending what you said about the commands for bzr being almost exact in comparison to cvs, I'd have to vote for bzr. 

That said however, I am neither an active contributor nor a user of either bzr or hg, so this vote can count for half :p

Hmm. It's possible there was a problem with dirstate that I never ran 
into. At this point most repos are in the packs format (same as git 
uses) and it seems to be working totally fine.

I'd say that probably a lot of what's showing up there is just issues 
found in Release Candidates. Not sure, though. I haven't encountered a 
serious issue in bzr in a while.

Hahaha, it was. :-)

Fair enough. I think bound branches is how we'd recommend users check 
out Bugzilla code, though, so that they could do "bzr up" and it would 
"just work" pretty nicely. 

As a result of having bound branches, bzr also has "lightweight 
checkouts", which are just a copy of the working tree without the entire 
history, and a pointer back to the main repo for operations that require 
the history. Of course, I've never used lightweight checkouts, and I 
don't know anybody who does. :-)

Cool. I will look into that if we go with Hg (though the way the voting 
is going bzr seems pretty likely).

Yeah, I wouldn't want to maintain Testopia without bzr, myself, if I 
were a maintainer. Of course, I think the "Testopia For Bugzilla 3.4" 
may not involve a patch to Bugzilla at all. We'll see. :-)

Yeah, agreed, but it's possible we'll see some community member come 
and pick it up.
