Please let's focus frist on the 3.0 final release before we start working on Git :)
Sure but I'd rather we quickly verify that the current SVNApp works with the GitHub
SVN integration for now.
Thanks

Hi everyone,
I'd like test the waters and see what you'd feel about moving XWiki's source
to GitHub.
Pros:
* Use Git instead of Subversion. Which means a better SCM especially wrt branching /
diagnosins bugs (bissect) just to name 2
Offline commits, and offline (and faster and more powerful) access to
the full commit history are very important in my opinion.
* More contributors since it's easy to
fork/branch and we can see contributor's patches (pull requests) and apply them way
more easily than with subversion
+ more visibility/recognition for the contributors, since they are
preserved as the authors.
* More collaboration in general between
committers and contributors
* A better SCM web site (check github.com - offers graphs/stats, views of forked/branched
repos, etc)
I wouldn't call it a better SCM site, since other tools offer nice views
of the repository. But it is a better source *collaboration* site since
it shows forks/branches/pulls very nicely.
* Good buzz for us (tech marketing)
* GitHub provides SVN integration (see
https://github.com/blog/644-subversion-write-support) which means we can continue using
SVN tools such as svnsearch, ohloh, our IDE integrations, etc
svnsearch won't be that needed since git/github offer many of those
tools natively, but the graphs from svnsearch are easier to obtain and
show live.
IDE integrations should work just as well (if not better) with Git.
* Less admin work and less maintenance since this
is handled by GitHub itself
* Good uptime on GitHub (probably at least as good as ours if not better)
* Improved developer spirit since most devs wants to start using Git
+1, I've been doing this for a couple of years already and I'm happy
with the experience.
* POM changes for the new repository configuration.
Cons:
* Have to learn a new SCM/new tools
* No integration of users with xwiki.org
Do you mean that access rights should be defined in xwiki.org as it is
now, with the CommittersGroup? I guess that's not possible. * Import/reorg work to be done obviously
I already started doing that, I should find some time to finish importing applications and plugins. Before doing the
final switch I
should re-synchronize with the svn repository.
Should the contrib repository be imported as well?
I'd say yes. We need to check how well the SVN integration works in GitHub
One problem is that the default size limit is for 300M
of data, and
we're already approaching that limit (thanks to the early non-maven days
when we bundled all the jars in our repo). I think that if we request
it, we'll be granted more space for free, as an open source project.
Well we better ask ASAP before we start any move since this is critical for a move.
* Reliance on
an external provider (but seen the other OSS projects there I'm not worried and
there's no lock in since your have the repos spread on all users' machines)
Yep, a lot of big names are moving there.
IMO the pros heavily outweight the cons.
WDYT?
+1.
And replying to your other mail, +1 for doing it after the 3.0 release,
but as soon as possible after that, so that we can get familiar with it
and iron out any quirks before the 3.1M1 release.
We should write a GitApp, similar to the SvnApp, which works directly
with a git repository.
