AIX has the same test_socket problem with FDPassSeparate as Darwin in Issue12958 so skip some tests. |

Failing tests: * testFDPassSeparateMinSpace (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgIntoSCMRightsStreamTest) It looks like the failure come from code like: self.sendmsgToServer([MSG], [(socket.SOL_SOCKET, socket.SCM_RIGHTS, array.array("i", [fd0])), and self.doRecvmsg(self.serv_sock, len(MSG), socket.CMSG_SPACE(SIZEOF_INT) + socket.CMSG_LEN(SIZEOF_INT)), In clear, there are errors on tests sending file descriptors through UNIX sockets. So this issue is a duplicate of #20718, but we may keep this one for AIX, and #20718 for OpenBSD. It looks possible to send a file descriptor between processes but using a pipe with I_SENDFD and I_RECVFD ioctl. See: http://www-01.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.commtrf2/I_SENDFD.htm http://www-01.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.commtrf2/I_RECVFD.htm http://search.cpan.org/~fractal/AnyEvent-FDpasser-0.3.0/lib/AnyEvent/FDpasser.pm |

The testFDPassSimple pass: it's possible to pass a file descriptor between two processes. Hum. The testMultipleFDPass test also pass: it's possible to pass multiple file descriptors. Both tests use SCM_RIGHTS. The testCMSG_SPACE test also pass. It looks like the difference between testMultipleFDPass and testFDPassSeparate is the number of "cmsgs" ("access ancillary data"): 1 cmsg for testMultipleFDPass, two for testFDPassSeparate. I don't understand if it is a bug in the Python socket.sendmsg() function serializing ancillary data, or "just" if the AIX kernel does not support multiple ancillary data for sendmsg(). @David: any idea? Did you ask IBM? |

I've updated the ref in the patch to this bug per Victor's comments, and applied. I'm not sure of protocol here. Do we close this ticket, or keep it open to analyze the actual cause? |

I'm not interested to investigate the issue on AIX. IMHO the feature is just not supported by the kernel so there is nothing to investigate except if you want to hack AIX kernel. |
