Of course.  That’s why I’m hoping to document it & perhaps get other people to contribute their experience.  One thing that tripped me up with addStepsAfterCurrentStep is that instead of taking the steps I give it it wraps them first in a factory & then creates the step which broke me setting the workdir on the step.  Not sure why that’s done but the workaround has been to modify the step manually after addStepsAfterCurrentStep.

Sure.  I understand that.  Just reporting my findings.

I am not using a proxy of any kind.  Connecting directly from my browser to the buildbot port on the same machine.

I know they are.  Haven’t quite gotten to the point where I need to debug this quite yet.  Still trying to get things to build.  I solved the workdir problem (addStepsAfterCurrentStep was behaving strangely).  Now the next thing that looks to be broken is slave scheduling.  The set of connected slaves moved out of the botmaster so I have to re-write that part of the code to work in 0.9 & 0.8.  It looks to be a little complicated at the moment.

When you load a page, the pinned state of the sidebar is reset.  Also, having the sidebar scroll in & out when I mouse over has been annoying.  I’d rather it just be expanded by default & if you unpin, then it just shows the “shortcut” view instead of sliding out on mouse-over.
