Changes

1.6 (2022-12-05)

• Pass name and parent as keyword arguments all over the place. Preparation for use of NodeInit behavior instead of DefaultInit. [rnix]

1.5 (2022-03-21)

• Replace deprecated use of Storage by MappingStorage. [rnix]

• Replace deprecated use of Nodify by MappingNode. [rnix]

• Replace deprecated use of Adopt by MappingAdopt. [rnix]

• Replace deprecated use of NodeChildValidate by MappingConstraints. [rnix]

• Replace deprecated use of allow_non_node_childs by child_constraints. [rnix]

1.4 (2021-10-21)

• Implement _list_factory on Podict and OOBTodict and use PersistentList for internal double linked list triples to allow transaction property detect changes. [rnix, jensens]

• Drop ZODB3. [rnix]

1.3 (2020-07-09)

• Access attrs when initializing nodes with ZODBAttributes behavior applied to avoid lazy creation. Needed to prevent _p_changed being set on first access. [rnix, 2020-06-23]

• Access storage when initializing nodes with PodictStorage or OOBTodictStorage behaviors applied to avoid lazy creation. Needed to prevent _p_changed being set on first access. [rnix, 2020-06-23]

• Use plumb instead of overriding __setattr__ to change __parent__ name to _v_parent on ZODBBehavior. [rnix, 2020-06-23]

• Use plumb instead of overriding __getitem__ to set parent on ZODBBehavior. [rnix, 2020-02-28]

1.2 (2017-07-18)

• Add python 3 support. [rnix, 2017-06-24]

• Add keys to OOBTodict and accept any number of *args and **kw to match expected contract by OOBTree and Fix tests with ZODB 5. [rnix, 2017-06-22]

• Add __nonzero__ and __bool__ to OOBTodict in order to make it work properly with ZODB 5. [rnix, 2017-06-22]

• Use @property and @property.setter for OOBTodict.lh and OOBTodict.lt. [rnix, 2017-06-22]

1.1.1

• Change ZODB install requirement to ZODB3. Latter one is a meta package as of version 3.11.0 and installs ZODB [rnix, 2017-06-19]

1.1

• Remove superfluous __repr__ function from OOBTodict. odict package properly outputs class name as of version 1.6.2. [rnix, 2017-06-14]

• Fix volatile_property to work on classes overwriting __getattr__. [rnix, 2017-06-14]

• Use plumbing decorator instead of __metaclass__ and __plumbing__ class attributes. [rnix, 2017-06-14]

1.0.1

• Add maintenance utilities. [rnix, 2014-05-13]
