web2.dav should be moved out to a separate project

[dreid]

This will allow web2 trunk to make changes which break compatibility with web2.dav. The idea is that it will let us speed up web2 development without having to refactor/rewrite all of the internally dependent dav code.

Presumably web2.dav should move to  http://calendarserver.org.

Once web2 is folded back into twisted.web (i.e. done) we can reevaluate adding dav back in.

This sounds like a great idea. I feel like Twisted's development style has gummed up the works for the DAV project as well, and I've felt a little bad about not being able to speed up reviews and help with integrating patches and such. I'm looking forward to streamlining processes for both projects, and the eventual re-integration of everything :).

Having a separate project on  http://calendarserver.org will also provide some higher profile for Twisted, since the actual calendar server page doesn't currently mention Twisted, but presumably a "DAV support for Twisted" page would.

One thing that might be good to consider while doing this is having some web plugin mechanism so that web2.dav (or whatever its new name will be) can be easily deployed as a plugin via the twistd command line. Maybe that's just a twistd plugin for dav, maybe it's something more.

Here's what I propose:

1. Merge the long-outstanding ACL branch (which is used by Calendar Server at calendarserver.org, web2.dav's most active user is using) down to trunk.
2. Delete web2.dav from trunk.
3. Create a branch for DAV, and add web2.dav there.

This enables web2 to continue development on trunk without being constrained by web2.dav. It becomes the web2.dav developers' responsibility to reconcile any problems by merging forward periodically. It also enables web2.dav to evolve a bit faster without affecting anything on trunk.

Some time after web2 is considered stable, web2.dav should be able to merge forward, become stable itself, then go back to review for a pull-down to trunk.

I would think it likely that a web2 release would happen without DAV before we do such a pull-down.

That advantage to this over pulling it out to another project is that we don't have to change the namespace out of twisted only to switch it back later, which is significant work on both web2.dav and its clients.

I talked to glyph about this yesterday, and he thought this would be a workable plan.

FWIW, attache patch is all removals except the last file (twisted/web2/tap.py).
