Bug #74290 [NEW]: [mysqlnd] Annoying "mysqli::close(): Couldn't fetch mysqli" warning

From: vedad at kajtaz dot net Operating system: FreeBSD 10.1 PHP version: 7.0.17 Package: MySQLi related Bug Type: Bug Bug description:[mysqlnd] Annoying "mysqli::close(): Couldn't fetch mysqli" warning Description: ------------ The following warning is generated by mysqlnd on mysqli::close() call when the server, upon receiving COM_QUIT, closes the connection instead of sending an OK_Packet: PHP Warning: mysqli::close(): Couldn't fetch mysqli in ... According to the MySQL spec, simply closing the connection is perfectly valid: https://dev.mysql.com/doc/internals/en/com-quit.html "response: either a connection close or a OK_Packet" Therefore, I believe this warning should be removed, as it does not report any unexpected behavior. One may overcome the issue using the @ operator, or disabling the error reporting for this specific call, but both the warning itself and the workarounds are a waste of CPU resources IMHO. -- Edit bug report at https://bugs.php.net/bug.php?id=74290&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74290&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74290&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74290&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74290&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74290&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74290&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74290&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74290&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74290&r=support Expected behavior: https://bugs.php.net/fix.php?id=74290&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74290&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74290&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74290&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74290&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74290&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74290&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74290&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74290&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74290&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74290&r=mysqlcfg
