[Twisted-web] Ampoule deferToAMPProcess confusion

[Jacek Furmankiewicz]

Can someone point me to some good docs on Ampoule deferToAMPProcess?
I am trying in vain to get the simplest possible example working, with no
success.

from ampoule import deferToAMPProcess, util
from twisted.internet import reactor, defer

def test():
    return "TEST"

@util.mainpoint
def main(args):

    @defer.inlineCallbacks
    def _run():
        val = yield deferToAMPProcess(test)
        print val
        reactor.stop()

    reactor.callLater(1, _run)
    reactor.run()

Gives:

exceptions.AttributeError: 'str' object has no attribute '_doCommand'

I've tried different combinations, returnd Deferreds from the test()
function, inline callbacks with defer.returnValue().
Can't get it to work.

Looks like I am not the only one:

Thanks in advance
