So as a test I created a nextSlave function to allow a job only if the slave is
idle. It sort of works except when getNext is called back to back. In that case
I get two builds scheduled on one machine when there should only be one. It
looks like the builder’s current builds hasn’t had time to be updated. Is there
a lock I could use? Or a pending builds list somewhere?
Thx.
def getNextSlaveIfIdle(builder, slaveBuilders, buildRequest):
master = builder.master
busySlaveNames = set()
for builder in master.botmaster.builders.values():
for b in builder.builder_status.getCurrentBuilds():
busySlaveNames.add(b.getSlavename())
for slaveBuilder in slaveBuilders:
if slaveBuilder.slave.name in busySlaveNames:
continue
print '*** Using %s for next build.' % slaveBuilder.slave.name
return slaveBuilder
print '*** No slaves available.'
return None

Thanks! I’ll give that a shot.

Hi,
The solution should be in custom nextSlave function.
For similar problem, I tried to use custom nextSlave(that should be the natural
solution) without success.
Currently I am using a 'ugly' combination of "nextBuild" /max_builds
Good luck,
Ciprian

Hi Everyone,
Is there a way to limit the number of builds per node for a set of builders?
I’m using a slave lock for that purpose on the builder and it’s not quite what
I’d like to happen. The builds start on a specific slave in the starting state.
But they’re waiting not starting and it makes it difficult in the UI to see
what is currently running. Also I’d rather the scheduling be performed
dynamically at the time slaves become free. Is there another way to do this?
