[Modeling-users] [Core] Release 0.8.5 / Important bug-fixes

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

        Hi all,

  Most of the changes included in this release are bug-fixes.

  The most important one adresses a bug which was defeating the uniquing
  principle of EditingContext when inheritance is involved ; this is
  demonstrated in:
    test_EditingContext_Global.test_05b_toOneFault_uniquing()

  !!! Users using inheritance are strongly advised to upgrade their
      copy, or they will certainly be bitten by this nasty bug. It
      causes very strange behaviour, such as an updated object A being
      modified when accessed from object B but left unmodified when
      accessed from object C.

      (Thank you SoaF for reporting this!)

  Note: this bug is only triggered by a given sequence of events, when
        different relationships point to different entities which are
        parents/children.

  Other changes are detailed in the changelog and are included at the
  end of the message.


About the near future:

  We are on our way to public v0.9, which has already been put in
  production for more than 3 months now and is considered stable. V0.9
  is still planned for the end of the week (it might be late a week,
  though). One or two minor releases will probably be necessary before =
0.9.


        Regards,

-- S=E9bastien.

0.8.5 (2003/02/10)
-----

  * EditingContext:

    - added: exception ObjectNotRegisteredError
             now raised by: deleteObject()

    - added: allInsertedObjects(), allUpdatedObjects, allDeletedObjects=
()
             see docstrings for details

    - implemented: arrayFaultWithSourceGlobalID()

    - UniquingTable: added support for ``root GlobalID'', and fixed
      addObjectForGlobalID(), forgetObject(), forgetObjectForGlobalID(),
      hasObject(). This fixes the following bug: when a relationship to
      an entity having a parent entity was triggered, it was possible to
      get a fault instead of the real object (when that object was
      already set).
      Cf. test_EditingContext_Global_Inheritance.test_05b_toOneFault_un=
iquing
      for more detail


  * Relationship.SimpleRelationship:

    - validateValue(): validation of a value being a fault now
      immediately succeeds and returns. We do not want to trigger faults
      when validating the values, faults are considered okay wrt. the
      validation logic.

    - setMultiplicityUpperBound() now accepts '*' for -1 (unconstrained
        toMany relationships)


  * ObjectStoreCoordinator:

      - fixed arrayFaultWithSourceGlobalID() which was not returning any
        value

      - Followed the change in the ObjectStore API: now implements
          ownsObjects() instead of handlesObject().

      - Misc: fixed a typo in saveChangesInEditingContext()/error
          msg. when changes are rolled back"
          Modeling/ObjectStoreCoordinator.py


  * QualifierParser.qualifierWithQualifierFormat: now allows upper-case
      for the first character in a key (e.g. "AGE =3D=3D NULL")
      (see also test_Qualifier.test_07_qualifierWithQualifierFormat4)

  * GlobalID: fixed KeyGlobalID.keyValues(): was returning the internal
      dictionary, making it possible to inadvertently change its
      read-only state.

  * Entity: Added: (module) primaryKeyForGlobalID()
                   (class)  primaryKeyForGlobalID() and primaryKeyForRo=
w()
           +Some docstrings now uses utils.finalize_docstrings

  * Adaptor: Added CannotSerializeException. adaptorWithName() now
      includes the traceback in the message of exception
      AdaptorImportError when an adaptor cannot be loaded'

  * tests: fixed test_Model.py (could not run individually, missing imp=
ort)
