Which IPC add-on module for Python

I need to be able to use some kind of inter-process (not threads in the same process) locking, like a semaphore or mutex.

I'm wondering which package to use, and, perhaps more importantly, which to avoid.

Right now this is for 2.4.3 but an update to 2.5 is certainly possible.

Which OS or OSes[0] do you want to support?


[0] I never remember the rules for plurals and apostrophes when the word ends in 's'.

Python cookbook  is always a good place to start.

@Chris - Linux variants - probably Red Hat and Debian

@Martin - this isn't a threading problem - this is for multiple processes, so real IPC is required.

Linux - most likely Red Hat but that probably doesn't matter in this case.


This is interprocess, not interthread, so those recipes don't seem to hit the spot.

The thread section also covers some IPC but there is also a section on ditributed apps.

If you are on unix you have aquite a few options.
Mailslots, named pipes, sockets. Basically anything in the unix API is covered in python.

There are a variety of solutions.
I think you should refine your requirement first.

Are these going to be persistent, one-to-one connections?

Are they more like client-server where one side is persistent but the other changes?

Will both sides come-and-go? (i.e. peer-to-peer)?

Are they on the same machine? (could you use shared memory?)

How much traffic? (a few msgs per/day, a few/second, 1000s/sec)?

Doesn't Python have support for SOAP, RPC and the like?
