Upgrade not efficient

[kaihendry]

Noticed that git fetches as part of our upgrade script are downloading the ENTIRE repo of ~2G from github instead of a delta.

This can be confirmed locally by:

git clone --no-local --depth 1 --bare /home/hendry/debian/sid-root/root/webconverger/chroot

My chroot has been git reset --hard a26424a19748cc6331cc8a174fb571d72a782b3c. Size it about ~350M.

cd chroot.git
git remote set-url origin https://github.com/Webconverger/webc.git
get fetch -v

github seems to throttle downloads at about 100KB/sec. So downloading 2G takes many hours.

To see the content of the fetch use git log ..FETCH_HEAD.

We are shooting forward with the --depth 1 approach initially proposed by @matthijskooijman

http://thread.gmane.org/gmane.comp.version-control.git/230134/focus=233490

To do this:

1. git/git@238504b needs to deployed by github

2. We need to adjust our upgrade scripts http://pastebin.com/0tGdgM0z http://pastebin.com/RQMvjHLk

Tbh I don't think (1) is vital, since it would be the same behaviour as the status quo, so we should work on updating and testing the upgrade scripts.

I've applied (2), now we are waiting for github to get back to us.

Oh this bug has been fixed!
