Hi, I didn't want to hijack the 'Twisted Presentation Materials..' thread, so I started this one ... First off, in the other thread, Glenn, you mentioned Storm. I have heard of Storm, but never got any deeper that noticing that it is still a work in progress (maybe things have settled down ?) If anyone has anything to say on how it might be a good choice with Twisted, please feel free to enlighten us! But, I hoping to solve some immediate problems with Twisted and SQLAlchemy, so ...
* A main "App Server", that controls high level access with "twisted.cred" * Web frontend: "twisted.web2" * Data: some "twisted.enterprise.adbapi", moving to SQLAlchemy.
Interesting; how are you handling asynchrony in SA? This is the issue that we're stilling unclear on, and I really would like to know of the best way of integrating Twisted with SQLAlchemy.
Twisted devs / experts: Please, could you comment on the right way of using Twisted and SQLAlchemy together. Anyone: If anyone know of existing code that integrates Twisted and SQLAlchemy nicely, please share! RIght away I just went about the problem be wrapping each call to SQLAlchemy in a "deferToThread" inside my "DatabaseManager" class. At startup of my app, I make an instance of this class, and pass it to each "avatar" (in "requestAvatar", in my portal) Here is my Database Manager: (you will actually see that I 'turned off' the deferToThread wrapping for now): http://trac.knoboo.com/browser/branches/knoboo-sqlalchemy-take2/knoboo/datab... but I really haven't convinced myself that this is the best way of doing things. Hell, it could be totally wrong, so if anyone has any advice, I would be very appreciative!
I'm aware of sAsync, but haven't looked much into it. (I'm a step or two behind you, actively using adbapi, and thinking about moving to SA when I get some breathing room.) I've looked into SAsync as well, but it is not totally clear to me what the extra benefit of it is (again, anyone who has a good description, please tell) The main developer of sAsync use to post to this mailing list, but I haven't seen him post in a fairly long while.
So, if others are thinking about using SQLAlchemy with Twisted, let's discuss it more. Thanks very much, Alex
