[Twisted-Python] Getting multiservice from running reactor
Can someone advise if it possible to obtain a service or multiservice object from the reactor object. I am interested in status of services in multiservice. Many thanks. Regards, David

There isn't necessarily a MultiService associated with the reactor, or there may be several. Most likely, whichever code you have which is interested in the state of a service should already have a reference to it, so it can just check directly. Jean-Paul
Hi Jean Paul. Yes, normally this is the case for sure. In this case, however, this is zope 3's startup and I cannot get a handle on the multiservice after zope bootstraps. I am interested in adding services to running reactor with some control on starting and stopping them. Is it not possible to determine what services the reactor is operating on another way. Many thanks.

You should probably make a feature request of the Zope 3 developers. They should offer a way to get the IApplication (or IService or whatever) that their setup code creates. If they aren't willing to do this (I don't see why they wouldn't be), then maybe you can think of ways to discover it, but any such way is going to be pretty hackish and an official Zope 3 API would be preferable.

Thanks Jean-Paul. I agree. I brought this up on Zope3-dev list about a week ago but it is sort of quiet on the list so no +1 or -1. I recommended a utility that could be accessed following bootstrapping to obtain the multiservice object or any other app There are already methods available in twisted for handling it afterwards. I'll likely try this again. Many thanks. Regards, David Jean-Paul Calderone wrote:
