'Clear View cache from here' action ignores CacheThreshold setting, performance issues/db deadlocks

    XMLWordPrintable

    Details

      Description

      Expiring view cache using the 'Delete view cache from here' menu option ignores the [ContentSettings],CacheThreshold setting.
      This can cause performance issues, and possibly even db deadlocks on sites with very large content trees and/or load.

      Steps to reproduce:
      • In site.ini, ContentSettings group, specify a low value for CacheThreshold (such as 25)
      • Enable kernel-content-edit condition in debug.ini
      • In the administration interface, click to view the root node; click class icon for the popup menu, and choose the 'Delete view cache from here' option.
      Result:

      The content objects will be cleared one by one, as can be verified in the debug log. sample:

      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      2
      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      2
      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      3
      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      2
      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      2
      [ Sep 04 2013 20:01:50 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      5
      ... (repeated for the number of objects)
      
      Expected Result:

      The CacheThreshold should be met, and a 'global' expiry issued. sample debug:

      [ Sep 04 2013 20:02:37 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      2
      [ Sep 04 2013 20:02:38 ] [192.168.56.1] count in nodeList <kernel-content-edit>:
      44
      [ Sep 04 2013 20:02:38 ] [192.168.56.1] eZContentCacheManager::clearObjectViewCacheArray:
      Expiring all view cache since list of nodes(44) exceeds site.ini\[ContentSettings]\CacheThreshold
