Req #52623 [NEW]: PDO::MYSQL_ATTR_MAX_BUFFER_SIZE not supported in mysqlnd

From: Operating system: any PHP version: 5.3SVN-2010-08-17 (SVN) Package: MySQL related Bug Type: Feature/Change Request Bug description:PDO::MYSQL_ATTR_MAX_BUFFER_SIZE not supported in mysqlnd Description: ------------ Seems as if mysqlnd driver doesn't support PDO::MYSQL_ATTR_MAX_BUFFER_SIZE constant. In pdo_mysql.c (from svn http://svn.php.net/repository/php/php- src/branches/PHP_5_3/ext/pdo_mysql/pdo_mysql.c), I can see: #ifndef PDO_USE_MYSQLND REGISTER_PDO_CLASS_CONST_LONG("MYSQL_ATTR_MAX_BUFFER_SIZE", (long)PDO_MYSQL_ATTR_MAX_BUFFER_SIZE); ... #endif So, this constant (and some others) are only defined when mysqlnd isn't the active driver. Test script: --------------- echo PDO::MYSQL_ATTR_MAX_BUFFER_SIZE; Expected result: ---------------- Output 1005 Actual result: -------------- Fatal error: Undefined class constant 'MYSQL_ATTR_MAX_BUFFER_SIZE' in php shell code on line 1 -- Edit bug report at http://bugs.php.net/bug.php?id=52623&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52623&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52623&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52623&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52623&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52623&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52623&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52623&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52623&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52623&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52623&r=support Expected behavior: http://bugs.php.net/fix.php?id=52623&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52623&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52623&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52623&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52623&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52623&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52623&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52623&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52623&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52623&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52623&r=mysqlcfg
