Re: [Python-Dev] sendmsg/recvmsg on Mac OS X

The buildbots are complaining about some of tests for the new socket.sendmsg/recvmsg added by issue #6560 for *nix platforms that provide CMSG_LEN.

Looks like kernel bugs: http://developer.apple.com/library/mac/#qa/qa1541/_index.html """ Yes. Mac OS X 10.5 fixes a number of kernel bugs related to descriptor passing [...] Avoid passing two or more descriptors back-to-back. """ We should probably add @requires_mac_ver(10, 5) for testFDPassSeparate and testFDPassSeparateMinSpace. As for InterruptedSendTimeoutTest and testInterruptedSendmsgTimeout, it also looks like a kernel bug: the syscall should fail with EINTR once the socket buffer is full. I guess one should skip those on OS-X.
