Zend Framework: Zend_Acl update - Dynamic loading and Zend_Config integration Component Proposal

Proposed Component Name Zend_Acl update - Dynamic loading and Zend_Config integration
Developer Notes http://framework.zend.com/wiki/display/ZFDEV/Zend_Acl update - Dynamic loading and Zend_Config integration
Proposers Aldemar Bernal
Revision 1.0 - 17 November 2007: Proporsal created. (wiki revision: 6)

Table of Contents

1. Overview

Zend_Acl update isn't meant to be a replacement of the current good implementation of Zend_Acl, it is just an update proporsal based on get better performance in the component in medium/large ACL implementations as well a new feature that allows Zend_Acl being created based on a Zend_Config_Xml object.

2. References

3. Component Requirements, Constraints, and Acceptance Criteria

  • This update will boost performance in medium/large Acl Implementations.
  • This update will allow the component to load only the needed Roles/Resources.
  • This update will allow to load the ACL from a Zend_Config_Xml object.

4. Dependencies on Other Framework Components

  • Zend_Acl
  • Zend_Role
  • Zend_Resource
  • Zend_Acl_Exception
  • Zend_Config_Xml

5. Theory of Operation

Dynamic Loading

This update doesn't make any change in current Zend_Acl implementations, it includes only a new method called registerLoader in the Zend_Acl component and a new abstract class called Zend_Acl_Loader_Abstract. The main object of this new feature is to be able to load dynamically Roles and Resources using an instance of the abstract class. Here an example is given to make clearer the new functionality and its use:

At bootstrap:

My_AclLoader.php:

So, as you could see in the example above, the Loader class will allow to avoid the problem of loading all ACL at once in bootstrap, and will only load the data needed.

6. Milestones / Tasks

Describe some intermediate state of this component in terms of design notes, additional material added to this page, and / code. Note any significant dependencies here, such as, "Milestone #3 can not be completed until feature Foo has been added to ZF component XYZ." Milestones will be required for acceptance of future proposals. They are not hard, and many times you will only need to think of the first three below.

  • Milestone 1: design notes will be published here
  • Milestone 2: Working prototype checked into the incubator supporting use cases #1, #2, ...
  • Milestone 3: Working prototype checked into the incubator supporting use cases #3 and #4.
  • Milestone 4: Unit tests exist, work, and are checked into SVN.
  • Milestone 5: Initial documentation exists.

If a milestone is already done, begin the description with "[DONE]", like this:

  • Milestone #: [DONE] Unit tests ...

7. Class Index

  • Zend_Acl
  • Zend_Acl_Loader_Abstract
