Hi,
PHP fails to set the socket_last_error when stream_socket_server() times
out.
It is therefore impossible to tell if a timeout occurred or if the call
failed for some other reason.
Here is a simple piece of that should help understand this issue:
<?php
// Call something that will set socket_last_error()
socket_create(AF_INET, SOCK_STREAM, 666);
$err = socket_last_error();
echo 'before: ', socket_strerror($err), "\t", $err, "\n";
// now call stream_socket_accept and timeout
$sock = stream_socket_server('tcp://0.0.0.0:0 <http://0.0.0.0:0>');
$client = stream_socket_accept($sock, 1);
$err = socket_last_error();
echo 'after: ', socket_strerror($err), "\t", $err, "\n";
PHP currently outputs:
before: Protocol not supported 43
after: Protocol not supported 43
I have a patch to fix this issue: http://pastebin.com/6JLjZkNu
The output then becomes:
before: Protocol not supported 43
after: Operation timed out 60
However the patch adds #include "ext/sockets/php_sockets.h" to
ext/standard/streamsfuncs.c. Is that something we are okay living with?
Thanks,
Alok
