Integration branching

["Kai Hendry" <hendry@aplixcorp.com>]

I've been asked to setup & host a git repo of an "integration branch"
of WebKit for our developers.

So I expected it to work like so:

git clone git://git.webkit.org/WebKit.git
git checkout -b test

<Make a few small changes and commit>

git-config remote.upload.url ssh://git.webvm.net/srv/git/webkit-test
x61:~/aplix/test/WebKit% git push --thin -v upload test
Pushing to ssh://git.webvm.net/srv/git/webkit-test
Counting objects: 371612, done.
Compressing objects: 100% (67851/67851), done.
Writing objects:  11% (43886/371612), 25.32 MiB | 88 KiB/

However when uploading the branch it seems to upload _everything_
which is far too big and impractical. Couldn't it just somehow
reference the remote branch and just publish the patch of the "small
changes"?

When doing a git-http-push instead of ssh, git resulted in a "Out of
memory" error:

   1. git clone git://git.webkit.org/WebKit.git # Check it out
   2. git checkout -b test # create a "test" branch and switch to it
   3. echo blah >> ChangeLog # change something
   4. git commit -a # commit that test change
   5. git-config remote.upload.url http://moto@moto.webvm.net/moto.git
# configure the upload url
   6. git push upload test # fatal: Out of memory, malloc failed

Was this the fault of the server(nox) or client(x61)?

x61:~% git --version
git version 1.5.4.5
nox:~% git --version
git version 1.5.4.4

So is there some better way of publishing a branch? Without uploading
the whole WebKit?



I did try something else, that was to create a webkit repo on the
server nox like so:

nox:/srv/git/webkit% git --bare init --shared
nox:/srv/git/webkit% git --bare fetch git://git.webkit.org/WebKit.git
master:master
git fetch -f git://git.webkit.org/WebKit.git master:master # again
forcing updates

And let developers branch from that. This proved a little cumbersome
as I need to manually force updates to webkit trunk when developers
asked me to do that.
However once a developer cloned ssh://git.webvm.net/srv/git/webkit.
Creating a test branch 'deleteme' and then `git push origin deleteme`
was extremely fast. So I guess this is the right way to achieve my
goals?


Any suggestions and tips would be greatly appreciated!
