Fix endless loop when mpd is launched from a non-interactive shell.
Thanks to _noth_ for the patch, this fixes Mantis bug #1534 _noth_ wrote: > When MPD is launched from a non-interactive shell, it enters an endless > loop, filling up its error log file with "error accept()'ing" messages. > This is caused by the fact that stdin is already closed when mpd starts > up. listenOnPort() opens up the first of its sockets as fd 0 (the first > empty fd table position). Then, setup_log_output()->redirect_stdin() > overwrites fd0 (fd=open("/dev/null",...); dup2(fd, STDIN_FILENO);) > without checking if it corresponds to the actual standard input (or if > it is open in the first place). This means that listenSockets[0].fd now > is a fd for /dev/null, thus doIOForInterfaces()->getConnections() can't > accept(2) on it and fails with the above error. The attached patch fixes > this for me. git-svn-id: https://svn.musicpd.org/mpd/trunk@6843 09075e82-0dd4-0310-85a5-a0d7c8717e4f
