From: Operating system: debian PHP version: 5.3.6 Package: MySQL related Bug Type: Bug Bug description:mysqlnd_ms_get_stats resets counter if refresh of page is frantic Description: ------------ I've tried to access the statistics on a simple page and if I keep ctrl+r pressed so that it gets 30 requests/s i've noticed that the counters are reset to 0 it doesn't happen if i reload the page slowly. Test script: --------------- <?php $dbuser="x"; $dbpasswd="y"; $dbname="z"; $mysqli = new mysqli("myapp", $dbuser, $dbpasswd, $db); $GLOBALS['MYSQLI'] = $mysqli; function my_query($mysqli, $query, $retry_count = 0) { // print("Is \"".$query."\" Select?". mysqlnd_ms_query_is_select($query)."<br>"); if ($retry_count > 3){ return false; } if (!($ret = $mysqli->query($query))) { /* Error: 1053 SQLSTATE: 08S01 (ER_SERVER_SHUTDOWN) */ if (1053 == $mysqli->errno) { /* ouch, slave is not available, try next... */ return my_query($mysqli, $query, ++$retry_count); } } return $ret; } $x = my_query($mysqli, " UPDATE users SET username = 'pippo' WHERE uid = 59 "); //SELECT * FROM pippo print("<pre>"); print_r(mysqlnd_ms_get_stats()); print("</pre>"); ?> Expected result: ---------------- i'd expect counters to grow anyway. Actual result: -------------- counters are reset to zero randomly -- Edit bug report at http://bugs.php.net/bug.php?id=54656&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54656&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54656&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54656&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54656&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54656&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54656&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54656&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54656&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54656&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54656&r=support Expected behavior: http://bugs.php.net/fix.php?id=54656&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54656&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54656&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54656&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54656&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54656&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54656&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54656&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54656&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54656&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54656&r=mysqlcfg
