[TYPO3-core] RFC #12130: Improve performance of flashmessages

[Rupert Germann]

Hi,

this is a SVN patch request.

Type: performance improvement

Bugtracker references:
http://bugs.typo3.org/view.php?id=12130

Branches: Trunk

Problem:
The current handling of flashmessages in the list module is very 
unefficient and slows down the BE if there are a a lot of messages. 
Every single flashmessage is stored in the DB causing a lot of database 
load.

Solution:
store the messages in a static object instead of using the DB.

Info:
The patch introduces a new class t3lib_Messages which is used to collect 
the flashmessages objects.
