It's a problem that also the "shared" cache is cleared - not only the trasactional.</SPAN><BR /><BR /><SPAN>I'd rather expect the service manipulates the cache smartly and inserts/changes the permisions entry in the cache - sounds like a common cache scheme. Is there some hidden point I am missing?</SPAN><BR /><SPAN>For me it's a little problem, cos I am having a performance issues resulting from permissions evaluations. I want to minimize the permissions loading from DB, and so caching would be enough. I even do some sort of cache pre-load. That would work but then a user invokes some common action that internally sets permission and all the cache is out.&nbsp; Would an update of the cache instead of clearing it be a problem to implement? </SPAN><BR /><SPAN>Thank you for any comments.</SPAN></BODY></HTML> Tue, 11 Mar 2008 19:07:41 GMT vycitalr 2008-03-11T19:07:41Z permissionsServiceImpl.setPermission always clears cache https://connect.hyland.com/t5/alfresco-archive/permissionsserviceimpl-setpermission-always-clears-cache/m-p/158606#M112698 Hello,I found that the permissionsServiceImpl.setPermission always clears the whole cache (permissionAccessChace).

Also in the downloaded 3.0.0.-dev nightly build the cache configs sitll contains the same setting about permissionAccessCache.</SPAN><BR /><SPAN>I did not go in any further detail examination, but I rather suppose this is still just planned but not done yet?</SPAN><BR /><BR /><SPAN>Regards Robert</SPAN></BODY></HTML> Wed, 02 Jul 2008 09:31:02 GMT https://connect.hyland.com/t5/alfresco-archive/permissionsserviceimpl-setpermission-always-clears-cache/m-p/158608#M112700 vycitalr 2008-07-02T09:31:02Z Re: permissionsServiceImpl.setPermission always clears cache https://connect.hyland.com/t5/alfresco-archive/permissionsserviceimpl-setpermission-always-clears-cache/m-p/158609#M112701 <HTML><HEAD></HEAD><BODY><SPAN>Hi</SPAN><BR /><BR /><SPAN>The cache is used when OLD style ACLs are found but not for new.</SPAN><BR /><SPAN>You need to look at all the code changes and not just see if the cache is still there <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></SPAN><BR /><BR /><SPAN>Andy</SPAN></BODY></HTML> Thu, 04 Sep 2008 10:37:20 GMT https://connect.hyland.com/t5/alfresco-archive/permissionsserviceimpl-setpermission-always-clears-cache/m-p/158609#M112701 andy 2008-09-04T10:37:20Z
