From: levi_tedder at hotmail dot com Operating system: Windows XP, Windows 2003 PHP version: 5.2.12 PHP Bug Type: cURL related Bug description: Multiple curl_exec and curl_close looses host
Description: ------------ If you have a web server host that responds very quickly and you're doing a lot of requests on it, curl will eventually respond "couldn't connect to host". This happens on my Windows XP machine and Windows 2003 server, but I've been unable to reproduce on Windows 2008. If I add a delay with usleep(50000) it seems to be ok. I'm not sure if this is by design, OS-restriction or wrong usage (I've tried forums) or actual bug. Please forgive misplacement. To get the script below to exit with "couldn't connect to host" you need a fast responding web server host. Reproduce code: --------------- <?php $url = "http://www.example.com";; for ($i = 1; $i <= 6000; $i++) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $result=curl_exec ($ch); if (curl_errno($ch)) { exit(curl_error($ch)); } else { curl_close($ch); echo "count: $i\n"; } } ?> Expected result: ---------------- count: 1 . . count: 6000 Actual result: -------------- count: 1 . . count 4322 couldn't connect to host -- Edit bug report at http://bugs.php.net/?id=50553&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50553&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50553&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50553&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50553&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50553&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50553&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50553&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50553&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50553&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50553&r=support Expected behavior: http://bugs.php.net/fix.php?id=50553&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50553&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50553&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50553&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50553&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50553&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50553&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50553&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50553&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50553&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50553&r=mysqlcfg
