Dear all, I am experiencing an issue with my twistd plugin. It is in a project_plugin.py file in the twisted/plugins directory of my project. Calling "twistd --help" works fine up to twistd version 16.3.2 but in 16.4.0 the plugin is not recognized anymore. This is how it looks like: from zope.interface import implementer from twisted.application.service import IServiceMaker from twisted.application import internet from twisted.plugin import IPlugin from twisted.python import usage from myfile import MyFactory class Options(usage.Options): optParameters = [["port", "p", 8000, "The port number to listen on."], ["my-hostname", "l", "", "the hostname of other server"], ["my-port", "i", 9000,"the port of the other server"]] @implementer(IServiceMaker, IPlugin) class MyServiceMaker(object): tapname = "myserver" description = "" options = Options def makeService(self, options): return internet.TCPServer(int(options["port"]), MyFactory(options["my-hostname"], options["my-port"])) serviceMaker = MyServiceMaker() Any help is appreciated.
