Memcached Functions for MySQL 0.5 (Default branch)
Memcached Functions for MySQL is a set of MySQL UDFs (user defined functions) to work with memcached using libmemcached. With these functions you get, set, append, prepend, and delete objects in memcached. You can also use memcached as a global sequence generator. With these functions you can use triggers to control your object caches. License: GNU General Public License (GPL) Changes:
This release adds expiration argument functionality to all functions that utilize it in libmemcached (set, add, and replace). Behavior has been updated to correspond with the latest libmemcached. An args processing function has been added to reduce redundancy. Tests have been added for expiration testing.Image

apache::session::lock::mysql

Apache::Session::Lock::MySQL(3pm)			User Contributed Perl Documentation			 Apache::Session::Lock::MySQL(3pm)

NAME

       Apache::Session::Lock::MySQL - Provides mutual exclusion using MySQL

SYNOPSIS

	use Apache::Session::Lock::MySQL;

	my $locker = Apache::Session::Lock::MySQL->new();

	$locker->acquire_read_lock($ref);
	$locker->acquire_write_lock($ref);
	$locker->release_read_lock($ref);
	$locker->release_write_lock($ref);
	$locker->release_all_locks($ref);

DESCRIPTION

       Apache::Session::Lock::MySQL fulfills the locking interface of Apache::Session.	Mutual exclusion is achieved through the use of MySQL's
       GET_LOCK and RELEASE_LOCK functions.  MySQL does not support the notion of read and write locks, so this module only supports exclusive
       locks.  When you request a shared read lock, it is instead promoted to an exclusive write lock.

CONFIGURATION

       The module must know how to connect to your MySQL database to acquire locks.  You must provide a datasource name, a user name, and a
       password.  These options are passed in the usual Apache::Session style, and are very similar to the options for
       Apache::Session::Store::MySQL.  Example:

	tie %hash, 'Apache::Session::MySQL', $id, {
	    LockDataSource => 'dbi:mysql:database',
	    LockUserName   => 'database_user',
	    LockPassword   => 'K00l'
	};

       Instead, you may pass in an already opened DBI handle to your database.

	tie %hash, 'Apache::Session::MySQL', $id, {
	    LockHandle => $dbh
	};
