[Buildbot-devel] master status

[Nick Trout]

I've had a rethink and it looks like I can use buildbot.status.client
and buildbot.clients.base.TextClient to do what I want. Just out of
interest, when do you use the client stuff for? Is the GTK client no
longer used, deprecated in favour of the waterfall?

There seems to be some interesting stuff in clients for development and
debugging. Some documentation here might help other developers get the
hang of setting up and debugging configs faster. E.g. it looks like
buildbot.clients.send is used to ping the master and tell it about a
false change to kick of a build. This would be pretty handy when you a
starting from scratch. I first had to touch files and check them in to
test BB to test sources and kick off builds. Now I've got a fake change
timer (see code below), but it looks like that step creator a better
solution.

I don't think BB is that hard to set up but if this code does what I
think it's supposed to do it would be handy to advertise it more because
it would definitely simplify setting up BB.

P.S. Just a small thing, at the bottom of buildbot. "master" is missing
as an argument in the test:   c = TextClient(master)


<<<<
# put this in master config to help debug setup

from buildbot import util
from buildbot.changes import base, changes
from twisted.internet.task import LoopingCall

class FakeChange(base.ChangeSource, util.ComparableMixin):
    """This source will poll a perforce repository for changes and
submit
    them to the change master."""

    compare_attrs = ["delay",]

    parent = None # filled in when we're added
    last_change = None
    loop = None
    volatile = ['loop']

    def __init__(self, delay):
        self.delay = delay

    def startService(self):
        self.loop = LoopingCall(self.check)
        self.loop.start(self.delay)
        base.ChangeSource.startService(self)

    def stopService(self):
        self.loop.stop()
        return base.ChangeSource.stopService(self)

    def check(self):
        c = changes.Change('Nick', ['z:/temp/something.txt',], "yeah",
revision=1)
        self.parent.addChange(c)
