[Buildbot-devel] Multiple factories for one Builder

Hi all,

I'm just starting to write factories for some of our processes. To  
help avoid duplication I was hoping to be able to chain factories  
together. For example, I'd like to have something like..

class MyBuildFactory(BuildFactory):

class MyUploadFactory(BuildFactory):


And in the master.cfg be able to tell a builder to run through all of  
the factories when doing a build, either by giving the Builder a list,  
merging them together myself, etc. It appears this is not a supported  
use case at the moment. I was wondering if I'm missing a feature here,  
or if it is just not possible. In the case the latter, is something  
that would be useful to others? I was thinking of adding some handling  
for it in the BuildFactory class. I _think_ if instances of  
BuildFactory() were handled in addStep, _makeStepFactory, and maybe  
__init__ it might just work.
