For what it's worth, there's some significant benefit to letting the person
doing all the work make the calls on the tools.  tcc has pretty much been
stopped for the last couple of years, and I'm happy just to see someone
working on it.

Rob, I appreciate the work you've done and encourage you continue in
whatever environment is most productive for you.

Can Savannah users commit to the existing tree using SVN, or would it need
be converted?

Yeah, there are already some people doing kernel development in hg, git and
are roughly equivalent tools easy to convert between in both directions.

One nice thing about mercurial is that there doesn't have to be one
URL to get it from, any more than you need one canonical FTP site to
stuff from.  You can have as many mirrors as you like, and keep them
by whatever means is convenient.  (I use rsync between my laptop and my web


I'd be happy to put a mirror of my hg repository up on another site, if
site had hgweb.cgi installed and anybody was interested.  Heck, anybody can

set up a mirror of my tree, right now, without me having to do anything.
(When you do an "hg clone" you get a complete local copy of the entire
repository history, you can re-export that just by putting it up on the web

somewhere.)  That's one of the great things about distributed source
and open source licenses.  And keeping a mirror in sync is just a cron job
doing an "hg pull -u" (or checking the rss feed, or however fancy you want

For my Firmware Linux project I already have two copies of the hg

http://engineering.timesys.com/hg/fwl both of which I upgrade via rsync
my ~/wwwsend.sh script (because I'm lazy, it was easy to script, and I
already had to set up ssh logins on those servers anyway).

CVS was a tool I stopped using in favor of SVN, because the new one could
things the old one couldn't (such as file renames).  And SVN was a tool I
stopped using in favor of Mercurial again because the new tool could do
things the old one couldn't (such as letting me do a checkin on my laptop
when I'm on the bus, on a 5 hour car trip, or at some place like Starbuck's

or Ikea that doesn't have free wireless internet).

I've been maintaining my own hg fork for several months now, just for my
personal use.  I've been collecting other people's patches, merging
clashing chunks, doing a little bit of my own development, fixing bugs I
reproduce, and so on.  I've now got over 30 checkins (of varying
that aren't in the savanah cvs.

The tinycc tree is just one of four mercurial trees on my website.  I've
got two of my own projects (firmware linux and toybox), plus an old version

of busybox up to when I stopped maintaining it.  I'm using mercurial for
tinycc both because it's easy and because it's what I'm using for

When I first started poking at tcc, the repository hadn't been touched in
months and going off in my own corner didn't seem particularly anti-social.

When Fabrice showed back up, I got out of his way:


And prepared broken out patches of everything I'd done to that point:


I then waited several months, and in the absence of renewed work on
(even to the point of catching up to where my tree had been), I started
poking at my tree again.

As for contributing to the official tcc version, "it's an honor to be
nominated" as they say, but it seems the suggestion is that I stop
maintaining my tree and do something else instead:

1) get an account on a system I otherwise don't use, run by an organization

whose politics I regularly disagree with, who seem to have set up their own

competitor to sourceforge for purely politicial reasons
(http://lwn.net/Articles/176582/), reasons I've publicly disagreed with in
the past (http://lwn.net/Articles/202106/).

2) switch back to an obsolete repository format using tools that clash
with my working style.  (Once you go to distributed version control, going
back to centralized is like using DOS again after a year on Linux.  It's
just...  Ow.)

3) backport six months of work nobody to get right back where my current
is, after having broken out the patches earlier and posted them to the
which got zero interest.

4) Still be the only active committer to said tree on anything like a
basis, doing essentially exactly what I was before, only now in a less
pleasant working environment.

This really isn't sounding like my idea of fun.  And if it's not fun, given

that this is a hobby competing with a half-dozen other major timesinks in
life (including several other software development projects), I'm unlikely
actually do much of it.
