Looks like a super nice way of doing threads in Python, here's the rep: https://github.com/dabeaz/thredo https://github.com/dabeaz/thredo Sad to see that it has not received any love for last 4 months, is there another "preferred" thread lib for Python?

I use threading and manage my own pool in a list (it really isn't difficult). That's the fastest method I have found.

twisted.internet.threads is always, always my go-to personally. Twisted is an amazing project and has especially shined brightly in the past 3 years or so.

  Twisted doesn't support Python 3, which is problematic for some projects. I've also always found the code it produces difficult to test.

    > Twisted doesn't support Python 3 No no, it now supports Python 3 wonderfully. It took a very long time, because a lot of what Twisted does was more dramatically changed from 2-3 than a lot of projects. Consider, for example, the implications of PEP-3333, which required that headers be in the native str type in Python 2, but also the native str type (ie, unicode) in Python 3. This was a tough problem. [0] However, those days are long behind us. Not only does Twisted support Python 3, but it can interchange its own flow control (ie, the reactor) with the asyncio event loop, and also convert (and ensure) that Futures and Deferreds fire in a way that is cross-compatible. You can also use the inlineCallback decorator to see all of the new coroutine syntactic sugar. Here's a project I'm working on right now that is Python 3.6+ with Twisted: https://github.com/nucypher/nucypher/ https://github.com/nucypher/nucypher/ > I've also always found the code it produces difficult to test. Yeah, I hear that a lot, and for my part, I've just never had that trouble, so I'm not sure how to respond. Have you ever read the "TDD with Twisted" document[1]? Also, the new pytest-twisted tooling helps quite a bit if you're using pytest. 0: https://github.com/twisted/twisted/blob/6ac66416c0238f403a8dc1d42924fb3ba2a2a686/src/twisted/web/wsgi.py#L26 https://github.com/twisted/twisted/blob/6ac66416c0238f403a8d... 1: https://twistedmatrix.com/documents/current/core/howto/trial.html https://twistedmatrix.com/documents/current/core/howto/trial...

      BTW, when writing in Twisted use @inlineCallbacks with yields for async code. The code reads as if it was synchronous then. @inlineCallbacks def get_index_status(self, index_id): uri = "{}/index-status?id={}".format(self.SERVER, index_id) #yes, no escaping, as this is silly test only r = yield self.get(uri) returnValue(r.text) Using raw Deferreds is a big more difficult.

    I've pushed Twisted on a 100M US company about 7 years ago and it has continued to work for us big time. The code - tens of thousands of lines in 20+ servers - survived Twisted upgrades for all these years without any changes (OK, there was one related to import, had to add PYTHONPATH=. to env). Kudos to Twisted team!

    I'm not a core developer, so I might be mistaken or missing big things, but from my perspective, the big things are (in addition to the stuff I mentioned above how flow control compatibility): Amber Brown took over as release manager, python 3 compatibility landed, lots of new test utilities, Glyph and some of the original authors took steps back but are still involved, IHandshakeListener (makes TLS easier), support for TLS 1.3 cypher suites (though full support is still pending PyOpenSSL I guess?), WSGIResource supports IPv6... I maintain a Twisted-based web server called hendrix; we have integrated many of the new coolness and are fully Python 3 compatible.

  Of course, but author is very clear on the early/alpha nature of the project plus there's uncertainty as to whether he will continue this as a project or not.. also he's the only contributor. In other words, if I build a codebase to rely on something other than the stdlib it's nice to know that it'll have at least some support down the line.

The stdlib threading and concurrent.futures library goes a long way. It's still up to the developer to understand threading well enough before digging in. I'm not sure any library can eliminate that need. I also use gevent a lot. I'm currently in love with cooperative multitasking.
