[users at bb.net] build properties from previous build

[Thomas Roos]

Thank you for the example Pierre - what I finally did is ugly, but it
works, any tips for making it nice are welcome:

def getLastBuild(builderStatus, currbuildid=-2):
        last_build = builderStatus.getBuild(currbuildid)
        if last_build is None:
            return
        else:
            return last_build

from buildbot.process import properties
@properties.renderer
def getBranchFromLatestBuild(props):
    status = props.getBuild().master.status
    builder = status.getBuilder("xxx_name_factory")
    b = getLastBuild(builder)
    return "echo " + b.getProperty("branch")


xxx_factory.addStep(shell.SetProperty(command=getBranchFromLatestBuild,
property="recent_branchurl"))
