[Modeling-users] Modeling/core v0.9pre11 released

[Sebastien B. <sbi...@us...>]

        Hi all,

  0.9pre11 has just been released!

Main changes are:

  - the constraint on to-many relationship for which an inverse to-one
    relationship had to be defined has been dropped, it is now possible
    to define a to-many relationship with no inverse. Special note: you
    should be very careful about this if you use
    CustomObject.snapshot_raw() or if you defined FK as class
    properties. Documenation for particular issues in this configuration
    is forthcoming; if you need it, please ask for it here.

  - A caching mechanism is now available for models at runtime,
    improving the general performance of the core --refer to appendix
    A.1 in the User's Guide for details:
      http://modeling.sf.net/UserGuide/env-vars-core.html

  - This release also includes some bug fixes, including: the ability to
    fetch raw '?' and '*' in "like" qualifiers (ticket #776592),
    RelationshipManipulation methods misbehaving when manipulating
    sub-entities (inheritance issue, ticket #776996)

  - Manipulation of custom data types, that was discussed here for
    assigning FixedPoint instances to an attribute, is now documented.
    See section 9:
      http://modeling.sf.net/UserGuide/attribute-custom-type.html

PS: Documentation for PyModels is not finished yet.

0.9-pre-11 (2003/07/28)
-----------------------

  * Removed the constraint on to-many relationships for which an inverse
    to-one relationship had to be defined.
    Details: recordChangesInEditingContext() refactored,
             recordUpdateForObject() implemented,
             model StoreEmployees changed.

  * Added Relationship.anyInverseRelationship() --plus entity Holidays in
    test model StoreEmployees, with a toMany rel. Employee-->Holidays having
    no inverse. This is the first step towards the removal of the constraint
    on to-many relationships that should have an inverse toOne rel. for the
    moment being.

  * Fixed bug #776996: RelationshipManipulation methods misbehaving w/
    inheritance. Implied fixing: Relationship.inverseRelationship(). Also
    added: entity.parentEntities()

  * Fixed bug #776592: was impossible to add raw '*' and '?' characters in a
    LIKE statement

  * Simple methods for models, entities, attributes, relationships and
    ClassDescriptions can now be automatically cached. This speeds up
    operations where model introspection is needed (when saving changes, wh=
en
    using RelationshipManipulation interface, etc.). See Appendix A.1,
    "Environment variables / Core" in the User's Guide for details.

  * Module RelationshipManipulation has been optimized and is now about 1.2x
    faster (2x faster with caching of models and class descriptions, see
    above)

  * Model, Entity, Attribute, Relationship, Join: replaced 'Unimplemented'
    exception with NotImplementedError

  * Added documentation: handling custom types for attributes (2003/07/21)
