PHP Bug Type: Sockets related
Bug description: fsockopen(unix_socket) and file descriptors leaking
Description:
------------
When using fsockopen with non "available" unix socket, fsockopen returns
FALSE (no file descriptor), but an unix socket remains opened in webserver
process running php.
run
watch -n 1 'lsof -U | grep ^apache | wc -l'
while opening the following page (replacing "apache" by the real name of
your webserver).
Suggestion : in file main/network.c, in function
_php_stream_sock_open_unix, when php_connect_nonb fails,
closesocket(socketd) should be invoked before returning NULL.
Reproduce code:
---------------
<?php
$PHPfd = fsockopen("/dev/null", 0, $PHPerrno, $PHPerrstr);
if($PHPfd)
{
fclose($PHPfd);
}
?>
<html><head><title>fsockopen</title></head>
<body>
<pre>
PID : <?php print getmypid() . " ". $PHPerrstr . "."; ?>
</pre>
</body></html>
Expected result:
----------------
When fsockopen returns FALSE, no file descriptor created by this function
should remain opened
