You want builders.py for all this information. builders.py didn't exist when rebaseline.py was written.

I can look again after some sleep.

This may not be worth being a single-line function.  But OK.

Seems you should add this to the baseclass too.  And it should return None?

Cute.  I'm not sure thsi is going to end up being our best design (I can't think of a parallel object in any nice framework I've written to before), but seems OK.  this is some sort of HTTPRequest object it seems.

Such a shame that we use this as a module instead of as a BuilderList object (which would be much more mockable).

I agree you should stop shaving yaks.  But you should fix the FIXME to say this should move to builders.py.

This function just about exceeds my mental length limit.  At least at 3am.  I would have found a way to split it I think.

Yeah, I'm nto sure the Web.py really adds much here.

Fixed.

Ok.

This object exists so we can mock out the network, just like the filesystem.

Done.

Ok.  I tried to make it smaller.

It's needed so that the unit tests don't actually try to fetch things from the network!

Thank you for splitting up rebaseline-test.  I'm still not convinced Web is going to be a long-term-useful API, but I will wait to judge. :)
