[Buildbot-devel] are Build Properties available in all steps?

[Philippe McLean]

I'm trying to do a clean build every X steps (this is a followup to an
earlier discussion).
I wrote a predicate on the SVN step, but the buildnumber Property does not
seem to be available to the SVN step (should I be asking an object inside
the step?)

(using buildbot 0.8.3 on Windows 2008)

My master.cfg:



def Purge(step):
    # purge the build every 4 builds
    modulus = 2
    buildnumber = int(step.GetProperty("buildnumber"))
    if ((buildnumber % modulus) == 0):
        return True
    else:
        return False

def DoNotPurge(step):
    if Purge(step):
        return False
    else:
        return True

# This build does an incremental of the DAVeOrders branch.
f3 = factory.BuildFactory()
f3.addStep(source.SVN(mode='update', baseURL='svn://XXX/',
defaultBranch='branches/XXX', always_purge=True, doStepIf=Purge))
f3.addStep(source.SVN(mode='update', baseURL='svn://XXX/',
defaultBranch='branches/XXX', always_purge=False, doStepIf=DoNotPurge))

The error:
