#35417 [NEW]: PDO_MySQL docs unclear about transaction safety

From: jbarros at mail dot com Operating system: Irrelevant PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: PDO_MySQL docs unclear about transaction safety Description: ------------ http://www.php.net/manual/en/ref.pdo-mysql.php claims that MySQL tables are not transaction-safe by default; however, whether a table is transaction-safe depends on the storage engine used. The distinction is unclear and may mislead readers. Current Wording =============== Beware: MySQL tables do not support transactions by default. When writing transactional database code, MySQL will pretend that a transaction was initiated successfully, even when no transactional support is present. In addition, any DDL queries issued will implicitly commit any pending transactions. Improved Wording ================ Beware: Some MySQL storage engines do not support transactions. When writing transactional database code on tables that don't support them, MySQL will pretend that a transaction was initiated successfully. In addition, any DDL queries issued will implicitly commit any pending transactions. -- Edit bug report at http://bugs.php.net/?id=35417&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35417&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35417&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35417&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35417&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35417&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35417&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35417&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35417&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35417&r=support Expected behavior: http://bugs.php.net/fix.php?id=35417&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35417&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35417&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35417&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35417&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35417&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35417&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35417&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35417&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35417&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35417&r=mysqlcfg
