Any reason for not using asyncio?

[dims]

@freeekanayaka : we could pose this debate if there's some actual proof of concept for what you are saying. can you please show us something that works? (at least subject to criteria from @mbohlool here (#114 (comment)) even if it is just python 3.x.

[mbohlool]

Please do let us know when you did those experiments. I am interested in seeing some kind of proof of concept. I think we need to continue support python 2. but that does not mean we can't have a separate async support for python 3. I will close this ticket, but please open it again any time you have more information.

This client is evolved from swager-codegen's generated client that uses urllib. It supports asynchronous calls but it creates a new thread. I am not familiar with asyncio much but from a glance, it is async in single thread that is nice. If it is possible to implement all functionalities required in rest.py and api_client.py using an asynchronous library, I have no objection. As long as the interface stays the same. I simply do not have time to research/do it in near future though.

Oh, look like asyncio introduced in python 3.4. We need to support both 2.7 and 3.X.

Yes, asyncio is Python 3 only. For Python 2 and 3 the equivalent technology would be Python Twisted, but it feels a stretch.

Personally I would value the possibility to write asynchronous code more than Python 2 compatibility (for the Python-written controllers/operators use case), but YMMV. So feel free to close the issue.

@dims I'm afraid for now I won't be able to provide that. I might start to experiment with Python-written controllers/operators in the near term, and when the time comes I'll probably write an asynchronous client, since I'm convinced it's the best model for such code (it's really and event-driven watch loop). If Python 2 support is a requirement for this particular client, it's probably best to stick with what you have and close this ticket, which was mainly me asking if you had considered asyncio as alternate option. Thanks!
