Hi, I would like to announce the availablility of the 'Concurrence Framework'. (http://concurrence.googlecode.com)
Basically it is a library build on top of Stackless that enables the easy creation of high performance network servers (http servers, chat servers, comet servers etc etc). It is similar in scope to the Twisted framework, but it uses a Lightweight-processes-with-message-passing approach to concurrency as opposed to Twisteds event-driven model. I have created this framework out of frustration with Twisteds model. After working for some years with Twisted it has become apparent to me that the event-driven model for IO/socket programming although very performant, quite easily leads to difficult to maintain program code... Instead I would prefer to program in a 'blocking' style like you would traditionally do with threads. At the same time I still would like to retain the performance and lack of threading issues of event-driven IO. This is what the Concurrence Framework provides... (trough Stackless and libevent) Most notably it already includes: - a Socket API, - a DBAPI 2.0 compatible implementation of a MySQL Driver - an implementation of a HTTP1.1/WSGI compliant webserver. Some components are implemented in Pyrex for speed (low level interface to libevent, IO buffer interface, low-level MySQL stuff). The code is currently quite usable, but some interfaces might still change as I gather feedback from the community. In the following weeks I will try to finalize the core documentation and I will create a proper website to host it. In the meantime, anyone interested can checkout the code from coogle code: svn checkout http://concurrence.googlecode.com/svn/trunk/ concurrence from there please follow the instructions in INSTALL.TXT (currently Linux/MacOSX only). Documentation can be found in doc/_build/html/index.html, but this is a work in progress... Examples used in the documentation can also be found in the examples directory. The unittests in the test directory could also provide some guidance on how to use the framework. Issues/feedback can be mailed to me or you can add an issue on http://code.google.com/p/concurrence/issues/list.
