Integration package for `plone.folder` into Plone


This package provides base classes for folderish Archetypes / ATContentTypes content types based on B-trees, a.k.a. “large folders” in Plone. Storing content in such folders provides significant performance benefits over regular folders.

The package only contains the integration layer for the base class provided by plone.folder, however. Please see there for more detailed information.


If you are using in your product you may notice that PloneTestCase will fail to setup a Plone site for your functional tests. This can be resolved by adding this line to your functional test source:

from import bbb

1.2.0 (2015-10-27)


  • Rerelease 1.1.1 as 1.2.0, because this is for Plone 5.0 and higher. [maurits]

1.1.1 (2015-10-27)


  • Use registry lookup for types_use_view_action_in_listings. [esteele]


  • Fixed test in combination with Products.BTreeFolder2 2.13.4 and higher. [maurits]

1.1.0 (2015-03-11)

  • Reduced dependencies and declared them explicit. Do not depend on Products.CMFPlone any more. Pep8fied et al. ATCT is now an extra require. Skip Zope2 old style interfaces. Stop Plone 3 support in 1.1 series (remove bbb+patches). Get rid of old outdated interface fallbacks. [jensens]
  • Remove profile, since Plone 4+ was no longer used anyway. [gforcada]

1.0.6 (2014-01-27)

  • Fix test for Plone 4, so we really only apply the reindexOnReorder patch when we are on Plone 3. [maurits]

1.0.5 (2013-01-13)

  • Only set up the folder content type if Archetypes is present. [davisagli]

1.0.4 - 2011-01-03

  • Depend on Products.CMFPlone instead of Plone. [elro]

1.0.3 - 2010-11-06

1.0.2 - 2010-08-08

  • Adjust tests to work with Zope 2.13 and avoid deprecation warnings. [hannosch]
  • Show the next viewable item in next/previous viewlet/link, as the behaviour was in Plone 3. This fixes [mr_savage]

1.0.1 - 2010-07-18

  • Update license to GPL version 2 only. [hannosch]

1.0 - 2010-07-07

  • Moved migration logic into the BTreeMigrationView to allow subclasses to override part of the logic. [hannosch]
  • Remove the overly noisy migration report per folder. [hannosch]

1.0b7 - 2010-06-03

  • Updated tests to not rely on the existence of the Large Plone Folder type, which was removed for Plone 4. [davisagli]

1.0b6 - 2010-05-02

  • Nogopip vs. Acquisition take two - not all folders have a getOrdering method, so we need to avoid acquiring it. [hannosch]

1.0b5 - 2010-04-06

  • Match getObjectPositionInParent behavior and handle unordered folders inside ordered folders shown in the navigation tree at the same time. [hannosch]

1.0b4 - 2010-03-06

  • Don’t try to store an acquisition-wrapped catalog on the positional index. [hannosch]

1.0b3 - 2010-02-18

  • Only apply monkey patch for reindexOnReorder on Plone 3.x & shortcut indexing completely if the fake index has been installed. [witsch]
  • Replace monkey patch for Catalog._getSortIndex with a fake index that can sort search results according to their position in the container. [witsch]
  • Add optimization for sorting results by folder position for the usual “all results in one folder” case. [witsch]
  • Add adapter for previous/next support that doesn’t need the catalog. [witsch]
  • Remove getObjPositionInParent catalog index and use a sort index based on the folder’s order information instead. [witsch]

1.0b2 - 2010-01-28

  • Add IATBTreeFolder to implements list of ATFolder replacement. [thet]

1.0b1 - 2009-11-15

  • Copy the index_html method from ATContentTypes to better support WebDAV. [davisagli]
  • Add in-place migration code. [witsch]
  • Work around imports no longer present in Plone 4.0. [witsch]
  • Briefly document the usage. [wichert]

1.0a1 - 2009-05-07
