[Modeling-users] Core / ZModeling v0.9pre8 released

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

        Hi all,

  This release has a number of small enhancements you've probably
already heard about :)

  - loading a xml-model is now 5 to 6 times faster,

  - in "base" mode, the Python code generation now gathers all files
    that are overwritten by a regeneration of the code, leaving the
    business-logic in the main classes untouched; a dry-run mode has
    been added (both mdl_generate_python_code.py and the ZModeler
    support this).

  - The db-connection dictionaries stored in models can now be stored in
    a single file, making it simpler to ensure these sensitive
    informations are well protected.
    (cf. http://modeling.sourceforge.net/UserGuide/env-vars-core.html,
         and look at MDL_DB_CONNECTIONS_CFG)

  Next release (pre9) will add the PyModels. Than 0.9 will be at hand...
  (we still lack a one-page tutorial)

    Cheers,

-- S=E9bastien.

0.9-pre-8 (2003/05/27)
---------

  * Loading a xml-model is now 5 to 6x faster: applied a patch submitted by
    Yannick Gingras <ygi...@yg...>. Thanks!

  * Fixed: creating/dropping a database could fail because of trying to
    rollback a cursor in autocommit mode

  [Merged from brch-0_9pre6-1-ModelMasons_base_generation_scheme]

  Summary: the ''base'' generation scheme has changed. Instead of putting
           Writer.py and WriterBase.py in the same package, it now generates
           a subpackage 'MDL' in which the base classes are dropped.

  * Added tests/test_generate_python_code.sh: tests the generation of python
    code in different situations, and it also checks that the appropriate
    python test (such as test_EditingContext_Global.py) succeeds with the
    generated code.
  Also added: xmlmodels/model_StoreEmployees.xml[2|3]

  * Updated documentation for ModelMason and PyModelMason

  * Added fake_mode to ModelMason, PyModelMason and option -n/--dry-run in
    mdl_generate_python_code

  * scripts/mdl_generate_python_code (option -B),
    PyModelMason.checkModelIsValid()): the 'base' scheme cannot generate a
    python-package from a model where a class and at least one of its (dire=
ct
    or indirect) subclasses leave in the same module. This is now checked a=
nd
    correctly reported when the generation cannot be done.

  * Added the 'MDL' sub-directory containing the files that are overwritten
    when mdl_generate_python_code.py (option: -B) regenerates a package
  [/merge]

  * RFE #726839: Added environment variable MDL_DB_CONNECTIONS_CFG; it poin=
ts
    to a single ini-file which centralizes the sensitive informations
    contained in each model's database connection dictionary (username,
    password). See tests/Postgresql.cfg for an example.
