From: Operating system: Win XP PHP version: 5.3.8 Package: cURL related Bug Type: Bug Bug description:curl_errno returns 0 instead of 6
Description: ------------ This issue concerns only multi curl. Single handle curl works correct and returns error no. 6 when host is not resolved. In the same situation multi curl returns 0 with curl_errno function despite the fact that curl_error returns error message. See codes of 2 examples below Test script: --------------- <? // Create a curl handle to a non-existing location $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://osms.pl'); // Execute curl_exec($ch); // Check if any error occured if(curl_errno($ch)) { echo 'Curl error: ' . curl_error($ch) . ' - ' .curl_errno($ch); } // Close handle curl_close($ch); ?> ------------------------------------------------------------------------------- <?php // create both cURL resources $ch1 = curl_init(); // set URL curl_setopt($ch1, CURLOPT_URL, "http://404.php.net/";); //create the multiple cURL handle $mh = curl_multi_init(); curl_multi_add_handle($mh,$ch1); $active = null; //execute the handles do { $mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); while ($active && $mrc == CURLM_OK) { if (curl_multi_select($mh) != -1) { do { $mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); } } echo 'Curl error: ' . curl_error($ch1) . ' - ' .curl_errno($ch1); //close the handles curl_multi_remove_handle($mh, $ch1); curl_multi_close($mh); ?> Expected result: ---------------- in first example: Curl error: Could not resolve host: osms.pl; Host not found - 6 in second: Curl error: Could not resolve host: (nil); Host not found - 0 -- Edit bug report at https://bugs.php.net/bug.php?id=60660&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60660&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60660&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60660&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60660&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60660&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60660&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60660&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60660&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60660&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60660&r=support Expected behavior: https://bugs.php.net/fix.php?id=60660&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60660&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60660&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60660&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60660&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60660&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60660&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60660&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60660&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60660&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60660&r=mysqlcfg
