[Rubygems-developers] Local installation w/deps (or, So I'm writing a Tinderbox...)

Well, Evan Phoenix wrote the Tinderbox web site and I've built (most
of) the gem runner. Maybe next week we'll have it all put together.
The basic idea is to install a gem into a sandbox (with
dependencies), run the gem's tests, then post the results of the
tests on a website to the shame of all who failed to make their tests
pass. (Maybe I'll even add a couple of leaderboards, including "most
assertions" and "most dooomed".) Anyhow...
My main issue is installing gems. I flushed out a few bugs I found
in Rubygems related to installing gems in a sandbox and have fixed
Now I have the problem of the discontinuity between local and remote
installation. Remote installation automatically installs all
dependencies. Local installation only installs the named gem.
I don't want to fetch every gem every time over the internet. That's
just not nice.
I don't want to re-write the three or four methods in RemoteInstaller
that handle dependencies into Tinderbox::GemRunner.
So, what's the plan to unify the two? I have the motivation,
interest, and time. I imagine the stupid-simple version would take
about a day.
Oh, instead, can I do something fancy with the gems in the cache
dir? If a file lives there does rubygems skip a trip out to the
internet? (I haven't looked, its late and the idea just popped into
And one more thing.
Tinderbox::GemRunner copies the source_cache from the host gem
repository into the sandbox to cut down on source_cache fetches, but
I still see a lot of them. Sometimes even back-to-back. Is there
something in Rubygems I should be poking at to make this go away?
Should Rubygems ever do a bulk update once it has a source_cache?
