Oops, the expected result should be:
server got line: test #1
server got line: test2
server got line: test3
server got line: test4
server done
client done

Description:
------------
stream_get_line() will block even though data has been received and there are lines ready to be
parsed in php's internal buffer.
It makes it impossible for example to implement a blocking HTTP server as the server will only parse
the first line in the HTTP request and then both the server and client will hang as both are waiting
for more data.
Test script:
---------------
$c = pcntl_fork();
if ($c > 0) {
$socket = stream_socket_server("tcp://127.0.0.1:10000");
$socket2 = stream_socket_accept($socket);
while (!feof($socket2))
print "server got line: " . stream_get_line($socket2, 1024, "\r\n") .
"\n";
print "server done\n";
} else {
sleep(1);
$socket = stream_socket_client("tcp://127.0.0.1:10000");
fwrite($socket, "test #1\r\ntest2\r\ntest3\r\ntest4\r\n");
fread($socket, 1000);
print "client done\n";
}
die(0);
Expected result:
----------------
client done
server got line: test #1
server got line: test2
server got line: test3
server got line: test4
server done
Actual result:
--------------
server got line: test #1
