Hi, The current Stackless socket module [1] could do with being replaced. If what I describe below appeals to anyone as something to work on, then please let me know.
The problems: - It does not scale. Being based on select, it is limited to handling 512 sockets at a time. - It is based on the 'asyncore' framework and because of this, is unnecessarily complicated. I've been playing with a more scalable solution for Windows [2]. It provides sufficient support for TCP, but none for UDP. I have no personal need for the IOCP-based Stackless socket module at this time, so it is unlikely I will complete it until I do. What I would like to propose, is that someone take the existing module [1] and using the pyiocp solution [2] as a guide, refactor it to use the 'select' module instead of asyncore. As I also mention above, the select functionality is limited to handling 512 sockets at any given time. If it is necessary, a solution to this might be to bundle sockets into sets of 512 and pass the sets through select one by one. Of course, on platforms other than Windows there may be other asynchronous IO solutions available within the 'select' module which do not have the limitation of select. A key aspect of the library should be that there are no dependencies over and above the standard library. And on Windows the pyiocp functionality can be brought in. There's a range of interesting things to learn about in this project: - Cross-platform asynchronous IO resources. - A wide range of socket functionality. Anyway, let me know if you are interested. Cheers, Richard.
