buildbot: Triggering Schedulers & WithProperties

Question

I am trying to use the WithProperties in Triggering Schedulers in an add step (see this link).

I need to use the same properties whatever parent job using same has to be used in child job.

The following is a snapshot of my master configuration file:

sandboxfactory.addStep(
     trigger.Trigger(
     schedulerNames=['installer-job'],
     waitForFinish=True,
     WithProperties("HOST_OS=%(buildername)s")))

However, I am getting the following configuration error:

2015-11-02 09:34:48+0000 [-]    exceptions.SyntaxError: non-keyword arg after keyword arg (master.cfg, line 351)

I tried basic configuration changes, still getting the same error.

Answer 1

buildbot config is just python file, so

def f(a, b):
    return a + b

f(a=1, 2)

things like this cause errors, you should write f(a=1, b=2) to fix this, in your case you should write set_properties={'something': WithProperties("HOST_OS=%(buildername)s")}
