Performance of AC Evaluation
----------------------------
Key: JCR-2573
URL: https://issues.apache.org/jira/browse/JCR-2573
Project: Jackrabbit Content Repository
Issue Type: Improvement
Components: jackrabbit-core
Affects Versions: 2.0.0
Reporter: angela
Assignee: angela
1. Performance in access control evaluation
=====================================================================
- main focus on
> read performance
> resource-based access control in .a.j.c/s/authorization/acl/*
- comparison admin vs. anonymous with full permissions
- comparision between shortcut and ACL-evaluation.
- comparison JR 1.4 vs JR 2.0 [actually i will compare Day's CRX as it already
provided
some custom AC stuff with JR 1.4]
2. Potential Problems
=====================================================================
I would expect the most significant problems to be found in
a) ACLProvider#retrieveResultEntries: calculating effective ACEs
for each session separately.
b) AclPermission:
Each instance registering an event listener in order to
keep the result cache up to date
c) AclPermission:
Resolution form Path to Item or to nearest existing Item
