git-svn: Having a "rare" structure

git-svn: Having a "rare" structure

[Marc Fargas]

Hi all,

First of all, please CC responses to me as I'm not subscribed to this list ;)

On the subject, I use git-svn to for most of my stuff and also to
"interact" with some SVN projects out there, there's one that is
driving me mad.

The Django project has a (somehow) rare SVN structure that I almost
managet to make git-svn understand, but a recent "rarity" to the
structure broke it again and I haven't succeeded in making git-svn
understand it, so I'm trying to get some guidance on how to make
git-svn understand the structure.

Right know the Django SVN repo is like that:
browse: http://code.djangoproject.com/browser/django
svn url:  http://code.djangoproject.com/svn/django

trunk/
tags/notable_moments/
tags/releases/
branches/*
branches/features/
branches/releases/

Until now, the last two didn't exist and git-svn was working nicely,
but now "features" and "releases" were created, and git-svn is taking
them as if they were branches, while they arent (branches are in
subdirectories of those two).

My git repo was done like that until now:

    git svn init --prefix svn/
http://code.djangoproject.com/svn/django -T trunk -b branches -t
'tags/*/*'
    git svn fetch

With that, git-svn understood that tags were in the subdirectories of
tags/{notable_moments,releases}/ but I can't do that with the branches
as there are branches also in the top branches/ directory.

I do not really care about those branches on the top directory as
those are old, so I really only need git-svn to understand the
{features,releases}/* thing. So:

How can I do something like "-b branches/{features,releases}/*" making
git-svn ignore the other top-level branches? Or, can I make it
understand both, the top-level ones and the ones inside those two
subdirectories?

Note that I just gueesed the "-b branches/{features,releases}/*"
thing; I didn't try it, tryiing takes lots of time and bandwidth ;\\

Thanks for all,
Marc

You can use "-T trunk -t 'tags/*/*'" and then set up the branches config
by hand:

git config svn-remote.svn.branches
'django/branches/features/*:refs/remotes/svn/features/*'

git config --add svn-remote.svn.branches
'django/branches/releases/*:refs/remotes/svn/releases/*'

In fact, you should be able to use your previous branches config when
fetching up to r9093, then switch to the config I suggested, and the
fetch from r9094.

Cheers,
Michael

I'll try it right now, I have one q... I've been fetching from svn so
I now have "like a mess" in the branches dir (and their history) is
there a way to make git-svn forget about everything after r9093 so I
can do the config change and re-fetch since then? That'd be awesome.

Thanks a lot for the tip! ;)

Sincerelly,
Marc

You can delete the bogus branches (using git branch -rd or git
update-ref -d), but I'm not sure if you can reset git svn's state info:
You may try messing with .git/svn/.metadata.

I tried the approach I suggested in the last post for real, and things
seem to work. Only gotcha is I don't know whether django folks will
stick with putting branches under {releases,features}, that would create
problems.

Cheers,
Michael

I'll try it, if not I'll recreate the repo from scratch ;)) Thanks for the tips!

They say they won't put more folders in branches/ ;))

Thanks again for the tips, that will solve lots of trouble. Thanks!

Cheers.
