ChangeLog (working copy)
Sun Jul 24 22:47:10 2011 Tanaka Akira <akr@fsij.org>
* backport r32579, r32581, r32587, r32588, r32598, r32638, r32655,
r32656, r32657 from trunk.
r32579:
* io.c (rb_update_max_fd): new function.
r32581:
* io.c (UPDATE_MAXFD): removed.
r32587:
* include/ruby/intern.h (rb_update_max_fd): declared.
* file.c: ditto.
* io.c: call rb_update_max_fd for each new fds.
* process.c: ditto.
* random.c: ditto.
* ruby.c: ditto.
* ext/openssl/ossl_bio.c: ditto.
* ext/pty/pty.c: ditto.
* ext/socket/init.c: ditto.
* ext/socket/socket.c: ditto.
* ext/socket/ancdata.c: ditto.
* ext/socket/unixsocket.c: ditto.
r32588:
* io.c (rb_update_max_fd): remove parentheses. they are not in
macro.
r32598:
* ext/socket/ancdata.c (discard_cmsg): workaround for MacOS X Lion.
r32638:
* io.c (rb_update_max_fd): validate fd.
* ext/socket/rubysocket.h (rsock_discard_cmsg_resource): add
msg_peek_p argument for the declaration.
* ext/socket/ancdata.c (discard_cmsg): add msg_peek_p argument.
assume FreeBSD, NetBSD and MacOS X doesn't generate passed fd
when MSG_PEEK.
(rsock_discard_cmsg_resource): add msg_peek_p argument.
(bsock_recvmsg_internal): call rsock_discard_cmsg_resource with
msg_peek_p argument.
* ext/socket/unixsocket.c (unix_recv_io): call
rsock_discard_cmsg_resource with msg_peek_p argument.
r32655:
* ext/socket/extconf.rb: test recvmsg allocates file descriptors for
fd passing even with MSG_PEEK.
* ext/socket/ancdata.c: use the above test result.
r32656:
* ext/socket/extconf.rb: fix the recvmsg test.
r32657:
* ext/socket/extconf.rb: refine the recvmsg test.
Sat Jul 9 19:25:02 2011 Yuki Sonoda (Yugui) <yugui@yugui.jp>
* ext/tk/extconf.rb: I gave up to fix the build issue of ext/tk with Windows
