PHP Bug Type: cURL related
Bug description: curl_multi work in single thread with socks5
Description:
------------
curl_multi does not processing multiple cURL handles in parallel when
SOCKS type proxies are used. This could be easily determined by checking
the spent time or by using any NET software to check amount of opened
connections for particular process (you will see that curl_multi opens one
or max two connections at a time)
Reproduce code:
---------------
$mh = curl_multi_init();
foreach ($servers as $server) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://google.com');
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_PROXY, trim($server));
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_multi_add_handle($mh, $ch);
}
$microTime = GetMicroTime();
do {
do {
} while (curl_multi_exec($mh, $stillRunning) ===
CURLM_CALL_MULTI_PERFORM);
} while ($stillRunning);
$timeSpend = GetMicroTime() - $microTime;
echo sprintf('%01.4f', $timeSpend);
Expected result:
----------------
The maximum spent time should be ~5 sec.
Actual result:
--------------
While the actual value vary from 20 till 35 sec.
p.s. If you will use simple HTTP type proxies the result will be as
expected ~5 sec.
