1020294 - Dynamic Jacuzzi Allocator shouldn't allow a job to have zero builders

Status: RESOLVED WONTFIX

(Release Engineering :: General, defect)

Description

[Pete Moore [:pmoore][:pete]]

Today we had to disable the dynamic jacuzzi allocator, because there were builders with zero slaves defined: https://bugzilla.mozilla.org/show_bug.cgi?id=1020210

It should not be possible for the jacuzzi allocator to allow a builder to reduce to zero slaves - possible one slave is also not ideal, but I think one should be the absolute minimum.

Previously we had the same issue, so it seems to be a repeating pattern. In any case, a simple check that at least one slave exists in each builder list - otherwise abort - should be sufficient.

I'm guessing this was fixed, as I never heard it come up again. Ben, do you know?

Just doing some bug hygiene :)

I have no idea...

WONTFIX because we're killing off jacuzzis in bug 1231367.
