#44553 [NEW]: curl_multi work in single thread with socks5

From: administrator at gesoft dot org Operating system: FreeBSD 6.1 PHP version: 5.2.5 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. -- Edit bug report at http://bugs.php.net/?id=44553&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44553&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44553&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44553&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44553&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44553&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44553&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44553&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44553&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44553&r=support Expected behavior: http://bugs.php.net/fix.php?id=44553&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44553&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44553&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44553&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44553&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44553&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44553&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44553&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44553&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44553&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44553&r=mysqlcfg
