Bug description: socket_read() produces warninigs on non blocking sockets
Description:
------------
Use of socket_read() on non blocking sockets produces warinigs like:
socket_read() unable to read from socket [35]: Resource temporarily
unavailable
I`m storing all php errors in log file /var/log/php.log.
This warning causes overflow of /var partition because socket_read()
called to wait icmp message.
Reproduce code:
---------------
$socket = socket_create(AF_INET, SOCK_RAW, 1);
socket_connect($socket, $host, null);
$startTime = microtime_float(true);
socket_send($socket, $data, strLen($data), 0);
socket_set_nonblock($socket);
while((microtime_float() - $startTime) < 0.5) {
$mt = microtime_float();
if (socket_read($socket, 255)) {
break;
}
}
socket_close($socket);
Expected result:
----------------
no warnings in php.log
Actual result:
--------------
I`m receive huge count of warinigs in my php.log file like this:
socket_read() unable to read from socket [35]: Resource temporarily
unavailable
