git daemon directory munging?

Scrapped right off the #git IRC channel...


<jdl> I stumbled across some git-daemon quirk for which I'd like opinions on
      possible solutions.						[18:56]
<jdl> I run a server that houses multiple virtual hosts on one physical
      machine.
<jdl> It has multiple Apache based websites on it, and I want to front
      multiple git repositories with gitweb.  That all works fine.	[18:57]
<jdl> But when I set up my repository stores, ie the /pub/scm/repo.git places,
      it falls apart.
<jdl> I want to maintain separate sets of git repos for each virtual site.
									[18:58]
<jdl> That is, www.foo.com can't see the repos of www.bar.com and vice versa.
<jdl> So I have an Apache directory set up that maps www.foo.com/pub/scm to
      some place like /pub/foo/scm using an alias for /pub/scm.		[18:59]
<jdl> Similarly, for www.bar.com I map /pub/scm to /pub/bar/scm
<jdl> Now, when I clone using http: all is well as it correctly maps the URL
      using the Apache Alias entry.					[19:00]
<jdl> However, when cloning via git: it doesn't do the Alias mapping based on
      the given website prefix part of the URL.
<jdl> I would have to clone using git://www.foo.com/pub/foo/scm even though I
      would clone using http://www.foo.com/pub/scm/			[19:01]
<jdl> So my proposed solution is to setup a genarlization of the git-daemon
      -baser-path=path argument.
<jdl> Instead of a single --base-path, there are potentially multiple
      --base-path entries that match multiple a URL prefixes.		[19:02]
<jdl> Thus, I'd use something like:
      --map-base=www.foo.com/pub/scm:/pub/foo/scm
      --map-base=www.bar.com/pub/scm=/pub/bar/scm			[19:04]
<dormando> mod_rewrite for git :|
<jdl> Quick prefix hack, yeah.						[19:05]
<jdl> Um, stop me before I hack....? :-)				[19:06]
<dormando> you're going to end up needing something that supports basic
	   regexes before long
<dormando> I can't think of many cases where you'd want to directly map like
	   that, and especially in that specific manner.		[19:07]
<jdl> I can't hear you.
<dormando> sorry.
