I think we should keep svn as canonical repo until we decide to drop 
support for 2.4. I think that none of my git-migration related work is 
backported. And even if that could be backported easily (I'd have to 
verify but I'm short in time right now) I wouldn't change the canonical 
repo until we are sure everything works as we want it. All that time, 
svn should be the main repo IMO and gitolite should consider the svn 
repo as upstream.

In git it's rather easy to decide later on to drop this upstream link.

I don't understand what you mean here.

Assuming the setup where svn is canonical, gitolite is configured with 
svn as upstream and github is considered a downstream from gitolite we get:
- a dev commits something to svn
- the svn post-commit hook runs a git command that causes gitolite to 
read in the new svn commits. I imagine some variant of our git-update 
script will be needed here (one that doesn't attempt to fast-forward 
checked-out branches)
- the updates in gitolite will eventually trigger gits post-received 
hook in which we push the changes through to github using git push 
--all. Here is also were the commit mails can be sent.

Once svn will be dropped, devs will push commits directly to gitolite, 
which will trigger the same git post-received hook to push to github and 
to send mails.

Which part is not clear for you ?
