Yay! :-) Welcome!

Yeah, we do the same thing upstream now (In 3.1).

Wow, dual master for MySQL, eh? I assume by "our own" means
that your wrote it yourself? What are you using to dual-master them?

That makes you, as far as I'm aware, the second largest
Bugzilla installation in the world, and because nobody knows anything
about the largest, you may be the largest.

We'd definitely love that. Have you seen any of our upstream
work on that?

Ha! I *knew* that would happen on large installations!! I feel
vindicated. :-) It's just that it's nearly impossible to discover that
in a test environment.
Anyhow, upstream is going wholly into transactions, which
should resolve it.

I seem to recall making a similar fix upstream, also. :-)

You'll see even more improvement with mod_perl, too. :-) That
six seconds is probably a lot of page-load and compile time.

Yeah, that's a well-known thing. Our idea was to AJAX it. What
did you guys do?

We might be willing to consider that upstream, but we'd have to
see that it was a technical advantage over other solutions, and that the
licensing allowed it to be shipped with Bugzilla.
Of course, within Yahoo it's the obvious choice, but for
upstream we have to have technical proof that it's the best choice. :-)

This is probably shameless self-promotion, but you might be
interested in VCI. :-)

That's neat. We just added a feature to show a picture for
groups, but pictures for individuals might be handy as well. Launchpad
does something like that.

Wow, and we're looking forward to your contributions! :-)
