Merge lp:~jelmer/launchpad/bzr-code-imports-ui into lp:launchpad/db-devel

[Jelmer Vernooij]

Remove the ability to register mirrored branches; instead, make it possible to register bzr code imports in the UI.

Make it possible to create new Bazaar code imports in the code import UI, disable the ability to create mirror branches.

This removes the user-visible distinction in the web UI between code imports (syncing from remote non-bzr branches) and mirrors (syncing from remote bzr branches), which should make the UI a bit easier to comprehend.

This doesn't migrate any of the existing mirror branches to be code imports, but that would be the next logical step.

It also doesn't remove the ability to create old-style mirrors via the API.

Otherwise, well it looks fine. It's great to see so much code being deleted. I don't have the time to do a line by line review, and I don't have the Launchpad dev environment set up on my new laptop so I can't play around with it. I worry that there are probably more places that implicitly assume import branches are foreign in some way, but maybe not (also approximately noone uses mirror branches any more aiui).

It would be SO GREAT if we could get rid of the puller after this. I think this requires having some kind of token mechanism that grants the holder of the token the ability to read and write to a particular branch (and read any stacked on branches I guess) via the usual codehosting access. But that can wait :)

Hi Jelmer,

Thanks for trying to clean up this UI. It has always been a bit of a mess. I think your simplifications are good.

Twice in browser/codeimport.py we have a list of valid RCS types. It would be nice to define those one place rather than using the same set of literals twice such as:

Another direction the UI could go of course would be to not overly
distinguish between the various import types and just let the foreign
branch plugins figure it all out. This feels like it would make for a
simpler user experience, but it would also certainly be a big change. I
wonder if it might seem a bit too magical?

That's an interesting idea. "bzr branch" has that magic to figure out
what format the source branch is in too, and it seems to work fine
there. One way to do this would be to add a "AUTO" value to
RevisionControlSystems that simply tries the probers registered for each
of the CodeImportWorkers. That would (I think) be a minimal amount of
work, though it would of course only work for those importers that
actually have probers (BZR, BZR_SVN, GIT, HG).

CVS would still need to be special, but I guess there's no way around
that anyway, as it requires a root and a module to be specified.

Cheers,

Jelmer

see config-manager for a url format for cvs that includes the root and module.

Yeah, that would be pretty neat, although presenting bzr/svn/git/hg/auto
to the user wouldn't really be progress :)

Apparently config-manager defines a URL format for CVS we could borrow.
But that would be more useful for cleaning up the internals, I don't
think we could get away with expecting the user to know about it.

Thanks for the review! I'll make sure to include screenshots next time.

Even if we do that, do we want users to have to know about that
particular format?
