I spent more time than I wanted installing Gerrit on our Snow Leopard Server at work so that we could streamline code reviews.  I’ve found dealing with diffs in email to be rather inconvenient, so I’m hoping that Gerrit will be a big help.

As I went through the process of installing Gerrit, I hit a speed bump at the end of the init process where it couldn’t create a required function (nextval_account_id()).

Here’s a log of what happened:

$ java -jar gerrit.war init -d /Library/Gerrit/

The solution is to make one change to the MySQL configuration before initializing Gerrit:

SET GLOBAL log_bin_trust_function_creators=1;

Thanks to Anthony on the Google Group for Gerrit for the answer.
