Products.CMFUid
===============

.. contents::

CMFUid introduces a simple unique id implementation.

Implementation
--------------

The supplied tools attach the unique ids to the objects. The objects
do not have to be aware of unique ids.

The current implementation depends on the portal catalog to find an 
object of a given unique id. The interfaces do not imply the use
of the catalog (except the IUniqueIdBrainQuery).

Which Tool does What?
---------------------

The 'portal_uidgenerator' tools responsibility is to generate 
unique ids. The 'portal_uidannotation' tool is responsible to 
attach unique ids to a content object, and enforce rules about
what happens on object move/create/delete. The 'portal_uidhandler' 
manages registering and accessing unique ids. 

This design was chosen to allow users replacing only parts of
the functionality without having to understand the whole thing.

Unique Id API
-------------

'portal_uidhandler' implementing 'IUniqueIdHandler' is the main 
API for playing with unique ids.
    
Usage
-----

'portal_uidhandler' fully implements IUniqueIdHandler (IUniqueIdSet
for registering/unregistering unique ids, IUniqueIdQuery for queries
and IUniqueIdBrainQuery for more efficient queries by returning 
catalog brains instead of objects).

The current implementation of get/queryBrain and get/queryObject 
do not return invisible objects (and brains of invisible objects).
By invisible objects, we mean objects that would be filtered out
by portal_catalog.searchResults due to expiry/effective date and/or
user roles.

It is often necessary to avoid this filtering in an application.
To do this, use the unrestrictedGet/QueryBrain and
unrestrictedGet/QueryObject as this will avoid 'None' results.

Have a look at the interfaces.

CMFUid's functionality is used by CMFDefault's favorite content type 
to follow linked objects. The favorite content type works as before if 
CMFUid is not installed. 


Update 2007-03-30
-----------------

The annotation code has been updated to use events for assigning/removing 
uids.  The settings for this live in the portal_uidannotation tool.

The default behaviour is:

- uids are NOT assigned when an object is created
  (it is assumed that other code is responsible for this)

- when an object is moved, a UID is not changed

- when an object is imported, any EXISTING UID is removed
  (this can be controlled via the 'remove_on_add' property)

- when an object is copied, any EXISTING UID is removed
  (this can be controlled via the 'remove_on_clone' property)

A more natural behaviour is for UIDs to be assigned automatically on 
creation.  To enable this feature:

- tick the 'assign UIDs on add' tickbox
  (uids will now be assigned when content is added or imported and any
  EXISTING uid will be replaced)

- tick the 'assign UIDs on copy' tickbox
  (objects will get a NEW uid when they are copied which will replace 
  any EXISTING uid)

In order to preserve the original behaviour of the tool, automatic 
assignment of uids is NOT enabled by default - it must be turned on in 
the uidannotation tool.

The behaviour is hooked in based on object creating/deletion/move events
for any IContentish objects.  The event handlers live in the 
UniqueIdAnnotation tool.

  [gforcada]


2.3.0-beta (2012-03-21)
-----------------------

- Made sure converted tools are used as utilities.

- Require at least Zope 2.13.12.


2.2.1 (2010-07-04)
------------------

- Deal with deprecation warnings for Zope 2.13.

- Fix markup error (Chameleon compatibility)


2.2.0 (2010-01-04)
------------------

- no changes from version 2.2.0-beta


2.2.0-beta (2009-12-06)
-----------------------

- no changes from version 2.2.0-alpha


2.2.0-alpha (2009-11-13)
------------------------

- moved the Zope dependency to version 2.12.0b3dev

- Cleaned up / normalized imports:

  o Don't import from Globals;  instead, use real locations.

  o Make other imports use the actual source module, rather than an
    intermediate (e.g., prefer importing 'ClassSecurityInfo' from
    'AccessControl.SecurityInfo' rather than from 'AccessControl').

- Add missing utility registration for IUniqueIdHandler.  See
  https://bugs.launchpad.net/bugs/299058 .

- UniqueIdHandlerTool: Call the reindexObject attribute of the object
  getting a uid, rather than portal_catalog's reindexObject.  This is
  needed to properly handle objects like the portal itself which shouldn't
  get catalogued ever.

- Removed redundant and unexpected code to auto-create catalog index and
  column for the UID handler tool. The index and column are already
  created by the default CMFUid GenericSetup profile.

2.1.2 (2008-09-13)
------------------

- no changes from 2.1.2-beta


2.1.2-beta (2008-08-26)
-----------------------

- completed devolution from monolithic CMF package into its component
  products that are distributed as eggs from PyPI.

- testing: Base UidEventZCMLLayer on ZopeTestCase.layer.ZopeLite.

- UniqueIdHandlerTool: Use %r instead of %s in error messages, so
  we don't trip over non-ASCII representations (e.g. File and Image).


2.1.1 (2008-01-06)
------------------

- no changes


2.1.1-beta(2007-12/29)
----------------------

- Testing: Derive test layers from ZopeLite layer if available.


2.1.0 (2007-08-08)
------------------

- Fixed all componentregistry.xml files to use plain object paths and strip
  and slashes. GenericSetup does only support registering objects which are
  in the site root.


2.1.0-beta2 (2007-07-12)
------------------------

- moved the Zope dependency to version 2.10.4

- Remove antique usage of marker attributes in favor of interfaces,
  leaving BBB behind for places potentially affecting third-party code.
  (http://www.zope.org/Collectors/CMF/440)

- Add POST-only protections to security critical methods.
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0240)

- UniqueIdAnnotationTool: Annotation handling has been switched
  from triggering it through old-style manage_*-methods to using
  events. UID assigning behavior has been made more flexible. Please
  review CMFUid/README.txt for information about the current
  behavior and the new features.
  (http://www.zope.org/Collectors/CMF/474)

- moved the Zope dependency to verson 2.10.2

- Tool lookup and registration is now done "the Zope 3 way" as utilities, see
  http://svn.zope.org/CMF/branches/2.1/docs/ToolsAreUtilities.stx?view=auto

- UniqueIdHandlerTool: Touching the internal UID value on a
  content item will not cause reindexing all indices anymore, only the
  specific UID index will be touched.
  (http://www.zope.org/Collectors/CMF/469)


2.1.0-alpha2 (2006-11-23)

  Now getBrowserCharset is used to play nice with Five forms. Customized
  setRedirect and getMainGlobals scripts have to be updated.

- Profiles: All profiles are now registered by ZCML.

- ZClasses: Removed unmaintained support for ZClasses.
  Marked the 'initializeBases*' methods as deprecated.

- Content: Added IFactory utilities for all content classes.
  They are now used by default instead of the old constructor methods.

- Content: All content classes are now registered by ZCML.
  ContentInit is still used to register oldstyle constructors.
