allow non-verbose darcs checkouts

[zooko]

I think the --verbose output from darcs is a performance problem for us, as we have many buildslaves doing a VCS checkout at the same time and they are overloading the network to the buildmaster by streaming back their --verbose output.

e.g.:

 http://tahoe-lafs.org/buildbot/builders/Randy%20FreeBSD-amd64/builds/169/steps/darcs/logs/stdio

I would like it if I could configure the Darcs command to be quiet instead of verbose. (Of course this ought to generalize to other VCS commands, too.)

We don't have a Darcs maintainer who could take care of this at the moment, but when we do, this would be a good starting point.

To make darcs be quiet, pass --quiet instead of --verbose.

Replying to dustin:

Dustin: I'm willing to write this patch.

Awesome! Ping the folks in #buildbot if you run into trouble.

I tested it with this buildslave which took 180 seconds to do a checkout:

but changing it from --verbose to --quiet made little difference (new total time 144 seconds; the difference could be due to other factors):

Then I upgraded darcs on that buildslave from darcs-2.0.2 to darcs-2.5.0 and the time (after darcs has established its slave-side cache) went down to about 6 seconds:

So: nevermind! Closing as wontfix.
