I fixed various bugs in the implementation of the (new) PEP 446: http://hg.python.org/features/pep-446
At revision da685bd67524, the full test suite pass on: (...)
I also checked the usage of atomic flags. There was a minor bug on Linux, it is now fixed (remove an useless call to fcntl to check if SOCK_CLOEXEC works). open(): On Linux, FreeBSD and Solaris 11, O_CLOEXEC flag is used. fcntl(F_GETFD) is only called once for all file descriptors, to check if O_CLOEXEC works. On Windows, O_NOINHERIT is used. socket.socket(): On Linux, SOCK_CLOEXEC flag is used, no extra syscall is required. os.pipe(): On Linux, pipe2() is used with O_CLOEXEC. On other platforms, os.set_inheritable() must be called to make the new file descriptors non-inheritables. On Windows, the atomic flag WSA_FLAG_NO_HANDLE_INHERIT is not used to create a socket. I don't know the Windows well enough to make such change. My OpenIndiana VM looks to be older than Solaris 11: O_CLOEXEC flag is missing. I regenerated the patch in the isssue: http://bugs.python.org/issue18571 Victor
