Bug #77946 [NEW]: Bad cURL resources returned by curl_multi_info_read()

From: phansys at gmail dot com Operating system: PHP version: 7.3.4 Package: cURL related Bug Type: Bug Bug description:Bad cURL resources returned by curl_multi_info_read() Description: ------------ cURL resources returned by curl_multi_info_read() aren't usables with curl_errno() or curl_errno(). When an error occurs with these resources, the "handle" returned doesn't behave as a single handle. I've created a draft PR with a test exposing the problem: https://github.com/php/php-src/pull/4075 Test script: --------------- $urls = array( 'http://nonexistent.tld', ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i] = curl_init($url); curl_multi_add_handle($mh, $conn[$i]); } do { $status = curl_multi_exec($mh, $active); $info = curl_multi_info_read($mh); if (false !== $info) { echo $info['result']."\n"; echo curl_errno($info['handle'])."\n"; echo curl_error($info['handle'])."\n"; } } while ($status === CURLM_CALL_MULTI_PERFORM || $active); foreach ($urls as $i => $url) { curl_close($conn[$i]); } curl_multi_close($mh); Expected result: ---------------- 6 6 Could not resolve host: nonexistent.tld Actual result: -------------- 6 0 -- Edit bug report at https://bugs.php.net/bug.php?id=77946&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77946&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77946&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77946&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77946&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77946&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77946&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77946&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77946&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77946&r=support Expected behavior: https://bugs.php.net/fix.php?id=77946&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77946&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77946&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77946&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77946&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77946&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77946&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77946&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77946&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77946&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77946&r=mysqlcfg
