From: [EMAIL PROTECTED] Operating system: Linux PHP version: 5.3CVS-2008-06-14 (CVS) PHP Bug Type: DBM/DBA related Bug description: Revisit locking in DBA for DB4
Description: ------------ The locking for DBA with DB4 needs to be revisited. The way DB_INIT_LOCK and DB_FCNTL_LOCKING are passed to DB4, and the use of DBA_LOCK_EXT in dba.c seem to be based on the assumption that BDB will do locking. This isn't true with the way BDB is used by DBA. See http://bugs.php.net/bug.php?id=45266 for why DB_INIT_LOCK isn't valid. DB_FCNTL_LOCKING is undocumented. It implies that PHP does locking. It just tells BDB when to release file handles. Perhaps the easiest solution is for dba.c to use DBA_LOCK_ALL, but I'm not fully aware of the implications of this flag. -- Edit bug report at http://bugs.php.net/?id=45267&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45267&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45267&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45267&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45267&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45267&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45267&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45267&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45267&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45267&r=support Expected behavior: http://bugs.php.net/fix.php?id=45267&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45267&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45267&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45267&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45267&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45267&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45267&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45267&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45267&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45267&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45267&r=mysqlcfg
