Ping.

Could someone with administrative rights on fdo please make an empty
git://anongit.freedesktop.org/mesa/demos repos, so that we can push this
branch into it?

Jose
Sorry for the delay.  I wanted to get a few things done right when
making the new repo:

1) Don't include all of the Mesa history to keep repo size down.
2) Keep history of the changes to the demos so annotate works.
3) Move the demos to src/ so people just coming to the project see a
  normal-looking tree.

This sure sounded easy with git-filter-branch.  We'd done something like
this with git-split for xcb, and git-filter-branch looked basically like
git-split but with more options.  The ugly part is that the tree-filter
takes a very long time, but git mv (unlike git rm) requires a
checked-out tree so you can't index-filter it.  Here's how the history
I've pushed came about.  I started with:

commit 1391db428fe7b8f3d1c078da98dc1a231b54347f
Author: Wiktor Janas <wixorp...@gmail.com>
Date:   Tue May 4 19:50:26 2010 +0200

   u_blitter: fix creating fragment shaders

   See FDO bug #27887.

   Signed-off-by: Marek Olšák <mar...@gmail.com>

And then:

# Remove everything in src/
git filter-branch --index-filter "git rm -rf --cached src" HEAD
# Remove all the do-nothing commits that now exist
git filter-branch --prune-empty HEAD
# Remove the nouveau import commit that was now empty, and confused the next 
filter
git filter-branch --parent-filter "sed 's|-p 
d57c2aff039d2a1422d0bc4d8e2b850c33d7e95c||'" HEAD
# Now actually move progs/ to src/
git filter-branch -f --index-filter \
   'git ls-files -s | sed "s-\tprogs/-\tsrc/-" |
        GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
        git update-index --index-info &&
        mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE' HEAD

Yuck.

Anyway, that resulting tree plus the changes I had in the other tree
rebased on it is now pushed to:

git+ssh://git.freedesktop.org/git/mesa/demos

I think commit messages are hooked up, too.
Very nice... though, shoudn't we also drop the docs, doxygen, include
and configs subdirectories?

Yeah, probably.  I'm calling it a night at this point though.  Also
fixed up the generated Makefile in revision control, pulled in the
changes from Mesa master that weren't in (except for the last cygwin
fix, and getprocaddress still needs work).

Looks pretty good, Eric.

Don't worry about the getprocaddress test for now, just omit it from the build.

There's a bunch of other clean-ups to be done (ex: convert more programs to use glew) that I'll try to do in my spare time.

Are we OK to start committing there?
