#1800: Implement faster portlet lookup
-------------------------+--------------------------------------------------
 Reporter:  madarche     |       Owner:  madarche 
     Type:  enhancement  |      Status:  new      
 Priority:  P1           |   Milestone:  CPS 3.4.4
Component:  CPSPortlets  |     Version:  TRUNK    
 Severity:  normal       |    Keywords:           
-------------------------+--------------------------------------------------
 The portlet lookup (as opposed to the portlet rendering) done by
 PortletsTool.getPortlets is slow and called many times when a page is
 rendered. Tests have shown that one can reduce the page rendering time
 from around 1/3 of a second by improving this part.

 The PortletsTool.getPortlets method has been modified in a branch with the
 aim of caching the portlet lookup :
 http://svn.nuxeo.org/trac/pub/log/CPS3/products/CPSPortlets/branches/getPortletsCache/PortletsTool.py

 This is just a first try at it and this needs to be finalized.

 === Things to be done ===

 * Invalidate the cache at every portlet modification (move, delete,
 duplicate, ...). Maybe this could be simpler to plug the invalidation
 mechanism as an event subscriber.

 * One should also think about the memory management (the 'rpath' parameter
 for example). JMO recommends a ZCacheable cache.

 * JMO also recommends to deal with the other parameters (override,
 visibility_check, guard_check) otherwise the portlet editor might not
 workor more simply to not cachewhen visibility_check=False ou
 guard_check=False ou override=False ...
