[Buildbot-devel] Multiple change sources and scheduler issues

[Duncan Ferguson]

Hiya,

I have set up my buildbot v0.77 with a number of change sources and  
Schedulers.  The problem I have is that when a change is detected all  
schedulers are triggered, not just the one configured for the  
particular svn repository.

Triggering all the schedulers hits hard - I am currently monitoring 15  
SVN repositories which build on 10 different os and arch  
combinations.  If I set up Nightlies instead I am building packages  
every night that might not have been changed in a few weeks, so its  
unnecessary work.  Setting up the builds as manually triggered doesn't  
make the best use of buildbot and wont necessarily pick up on bad  
commits until the packages are needed (and then its a scrabble to get  
the issue sorted).

Below is a cut down example of how I have set this up (I don't know  
python at all so the below might not be as efficient as it could be)  
but I hope with will give enough insight - what am I missing or what  
have I done wrong?  How are schedulers meant to be associated with a  
particular change source only?

Thanks

   Duncs
