Comment 7 for bug 1455993

Okay, got the scripts working again.

In addition to adding those new arguments I ran into a couple of hiccups:

1. I refactored the mahara-scripts repository so that the gerrit hook scripts are now in a subdirectory called "gerrit". I updated Gerrit's symlinks to point to the new location, but Gerrit still refused to actually call the new scripts until I restarted it.

2. The Gerrit 2.11 manual is missing one argument that gets passed to change-merged: "--newrev <new rev>". So I had to add that as well. I've filed a bug with Gerrit asking them to update their documentation: https://code.google.com/p/gerrit/issues/detail?id=3374&thanks=3374&ts=1431921610

Marking this one "Finished" now. :)
