Hello, my name is Greg.
I've just started using python after many years of C programming, and I'm also new to the list. I wanted to clarify this first, so that maybe I will get a little less beating for my stupidity :)
Browsing the net I've found a patch to the python core (http://bugs.python.org/issue1194378), dated 2005.
First of all, I would like to ask you guys, whether you know of any way of doing this FD passing magic, or that you know of any 3rd party module / patch / anything that can do this for me.
Aside from the patch in the tracker, there are several implementations of these APIs as third-party extension modules.
Since I'm fairly familiar with C and (not that much, but I feel the power) python, I would take the challenge of writing it, given that the above code is still somewhat usable. If all else fails I would like to have your help to guide me through this process.
What would be great is if you could take the patch in the tracker and get it into shape so that it is suitable for inclusion. This would involve three things, I think:
1. Write unit tests for the functionality (since the patch itself provides none) 2. Update the patch so that it again applies cleanly against trunk 3. Add documentation for the new APIs
Once this is done, you can get a committer to look at it and either provide more specific feedback or apply it.

Hello again So, after a little cleanup I've managed to integrate the code into socketmodule.c/h. It works fine now, though I needed to add it to Lib/socket.py, otherwise it wouldn't show up in the socket module (I've searched for recvfrom and added it). I've also cleaned up the code a little, fixed some codingstyle issues (which might still exist). Since I am not a python core developer the patch might still be in a pretty outdated state. I'd like someone to look it over and direct me to some documentation (the ones I've found so far were pretty sketchy), for it to be acceptable for inclusion. The sanity of the code is what matters to me the most. I've looked it over though and found it in a sound state, but I guess you guys might have a different opinion about that ;) With writing the test cases, some documentation would be nice. I've attached the patch generated with svn diff for revision 73434, and the test code that I use to pass a file descriptor between processes. It works just fine :). Thanks Kalman Gergely
