speeding up repo sync over ssh

[Shawn Pearce]

I just posted a patch for repo
(https://review.source.android.com/9507) that can cut the time for a
no-op (no new changes) sync of AOSP (via SSH) on my desktop from 60s
to 17s.

Unfortunately, if your SSH daemon is Gerrit it also triggers a
protocol incompatibility between the OpenSSH command line client and
the Gerrit SSH daemon; the client spews state machine errors. The
sync appears to go through correctly, but the state machine errors
give me some pause because I can't be 100% sure that the two sides
haven't gotten out of sync and somehow crossed data streams. So the
patch is on the back-burner until I can fix the SSH daemon.

But... repo sync is going to get faster. Soon.

Am I getting this right? You maintain two manifests, one with git://
and one with ssh:// acess methods?

I have been toying with that idea in my mind for our project, but I
was trying to figure out a way of not repeating myself... do you have
such a thing?

Yes.

Sometimes people use a url.insteadof in their ~/.gitconfig to rewrite
the AOSP git://android.git.kernel.org/ URLs to a local mirror, rather
than edit the manifest. I prefer just editing the manifest. In the
specific case I was testing against today, its an SSH based mirror of
AOSP, within Google.
