Kristján Valur Jónsson <krist...@ccpgames.com> added the comment: I can't see how that patch has anything to do with it. The problem has been present since at least 2.5. Your patch fixed it for timeout>0.0 but left the 0.0 case still broken.
It comes from these lines in init_sockobject: { s->sock_timeout = defaulttimeout; if (defaulttimeout >= 0.0) internal_setblocking(s, 0); } This code assumes that the socket's internal state is always blocking, and so only switches it into the non-blocking state if required. Now, you fixed the 'accept' case with your socket.py patch, but you left out the case where accept_socket.gettimeout() == 0.0. In other words, you fixed only accept_socket.gettimeout() > 0.0 We can fix it to be as advertized, except that the second part is not possible: "if the listening socket is in non-blocking mode, whether the socket returned by accept() is in blocking or non-blocking mode is operating system-dependent. If you want to ensure cross-platform behaviour, it is recommended you manually override this setting." The reason is that it is impossible to _ask_ the socket whether it is blocking or non-blocking and therefore, accepted_socket.gettimeout() will not be truthful. imho, we should just simplify this rule and have the accepted socket inherit the accept socket's properties if defaulttimeout() == None, and not make this special case. I'll prepare a demonstration patch. I've added a suggested patch. p.s. My comments about fixing things in socketmodule.c were only half correct. I didn't realize that accept had been broken into _accept and socket() in py3k. ---------- hgrepos: +14 Added file: http://bugs.python.org/file21490/defined.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7995> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
