Hi, I opened a thread on this mailing list one month ago to find a new maintainer for the Trollius project. Since I didn't get any concrete reply, I decided to deprecate the Trollius project.
DON’T PANIC! There is the asyncio project which has the same API and is well maintained! Only trollius is deprecated. I wrote a long list of reasons explaining why I chose to deprecate Trollius: http://trollius.readthedocs.org/deprecated.html#deprecated The most recent reason is that supporting the PEP 479 in Trollius is painful, whereas this PEP doesn't impact asyncio: https://www.python.org/dev/peps/pep-0479/ In the meanwhile, I removed the trollius code from the OpenStack Oslo Messaging project which was my first and only concrete change in OpenStack using trollius: https://review.openstack.org/#/c/281173/ I also modified the dependencies of the OpenStack Gnocchi project to not install Trollius on Python 3, since the code already used asyncio from the Python standard library. To stop using Trollius, Gnocchi might "simply" dropped Python 2 support. Well, it's my hypothesis, I don't think that it's going to happen in the short term. For OpenStack, there is a remaining project which strongly depends on Trollius: Zaqar uses Trollius for websockets. I know that there are many libraries for websockets on Python 2, but I didn't check how hard it would be to modify Zaqar to use anything else. Victor
