It seems that the multiprocessing module in 2.6 is broken for *BSD;
I've seen issue 3770 regarding this. I'm curious if there are more
details on this issue since the posts in 3770 were a bit unclear. For
example, one post claimed that the problem was that sem_open isn't
implemented in *BSD, but it is available on FreeBSD 7 (I checked). I'd
be willing to help get this working if someone could point me in the
right direction.
Hi Al,
I don't know anything about the multiprocessing module, but I have
some recent experience with the semaphores on FreeBSD 6 & 7 as a
result of implementing my posix_ipc module.
Since you mentioned sem_open, I assume you're talking about POSIX
semaphores, rather than System V semaphores, yes? On FreeBSD 6 & 7
sem_open exists and works, but support for said semaphores are listed
as "very experimental". I experienced a problem that looked like a bug
to me, and a rather big one at that. There's more detail here (scroll
down to the part about FreeBSD 6/7) including a link to the bug report
I filed against the FreeBSD kernel:
