  Log Message:
  -----------
  - When adding an item to ``MongoContainer`` and the key is ``None``, then the
  OID is chosen as the key. Ids are perfect key, because they are guaranteed
  to be unique within the collection.

  Log Message:
  -----------
  - Since people did not like the setitem with ``None`` key implementation, I
  also added the ``MongoContainer.add(value, key=None)`` method, which makes
  specifying the key optional. The default implementation is to use the OID,
  if the key is None.

* Added processSpec to the CollectionWrapper. Removed manual calls to
  processSpec() and make sure the wrapper is used everywhere.

  Get ready for release. I have tested this code with our application and 
a lot of the odd quirks are gone now. I successfully removed all intermediate
transaction.commit() calls in our application and mongopersist now behaves a
lot like a native ZODB app.

  Log Message:
  -----------
  - Bug: When a transaction was aborted, the states of all *loaded* objects were
  reset. Now, only *modified* object states are reset. This should drastically
  lower problems (by the ratio of read over modified objects) due to lack of
  full MVCC.

  Log Message:
  -----------
  - Feature: Conflicts are now detected while aborting a transaction. The
  implemented policy will not reset the document state, if a conflict is
  detected.

- Feature: Provide a flag to turn on MongoDB access logging. The flag is false
  by default, since access logging is very expensive.

- Bug: We have seen several occasions in production where we suddenly lost
  some state in some documents, which prohibited the objects from being
  loadable again. The cause was that the ``_original_states`` attribute did not
  store the raw MongoDB document, but a modified one. Since those states are
  used during abort to reset the state, however, the modified document got
  stored making the affected objects inaccessible.

  - Feature: ``ConflictError`` has now a much more meaningful API. Instead of
  just referencing the object and different serials, it now actual has the
  original, current and new state documents.

    M src/mongopersist/tests/test_serialize.py

  Log Message:
  -----------
  - Feature: A new ``IConflictHandler`` interface now controls all aspects of
  conflict resolution. The following implementations are provided:

  * ``NoCheckConflictHandler``: This handler does nothing and when used, the
    system behaves as before when the ``detect_conflicts`` flag was set to
    ``False``.

  * ``SimpleSerialConflictHandler``: This handler uses serial numbers on each
    document to keep track of versions and then to detect conflicts. When a
    conflict is detected, a ``ConflictError`` is raised. This handler is
    identical to ``detect_conflicts`` being set to ``True``.

  * ``ResolvingSerialConflictHandler``: Another serial handler, but it has the
    ability to resolve a conflict. For this to happen, a persistent object
    must implement ``_p_resolveConflict(orig_state, cur_state, new_state)``,
    which returns the new, merged state.

  As a result, the ``detect_conflicts`` flag of the data manager was removed
  and replaced with the ``conflict_handler`` attribute. One can pass in the
  ``conflict_handler_factory`` to the data manager constructor. The factory
  needs to expect on argument, the data manager.

  Log Message:
  -----------
  - Feature: Whenever ``setattr()`` is called on a persistent object, it is
  marked as changed even if the new value equals the old one. To minimize
  writes to MongoDB, the latest database state is compared to the new state
  and the new state is only written when changes are detected. A flag called
  ``serialize.IGNORE_IDENTICAL_DOCUMENTS`` (default: ``True``) is used to
  control the feature. (Experimental)

  - Performance: Drastically improved performance for collections that store
  only one type of objects and where the documents do not store the type
  (i.e. it is stored in the name map collection).

    M src/mongopersist/zope/container.py

  Log Message:
  -----------
  - Performance: The Zope Container fast load via find() did not work correctly,
  since setstate() did not change the state from ghost to active and thus the
  state was loaded again from MongoDB and set on the object. Now we use the
  new ``_latest_states`` cache to lookup a document when ``setstate()`` is
  called through the proper channels.

Between this and the previous checkin, fast loading is now 30 times 
faster than before.

  accomplished by removing unnecessary database accesses, better caching and
  more efficient algorithms. This results in speedups between 4-25 times.

  Log Message:
  -----------
  - Implemented several more mapping methods for the Mongo Container, so that
  all methods getting the full list of items are fast now.

- Bug: When looking for an item by key/name (``find_*()`` methods) , you would
  never get the right object back, but the first one found in the
  database. This was due to clobbering the search filter with more general
  parameters.

  Log Message:
  -----------
  - Feature: The new ``IdNamesMongoContainer`` class uses the natural Mongo
  ObjectId as the name/key for the items in the container. No more messing
  around with coming up or generating a name. Of course, if you specified
  ``None`` as a key in the past, it already used the object id, but it was
  sotred again in the mapping key field. Now the object id is used directly
  everywhere.

the time but cached. DBRef's are generally considered immutable.

  * Overwrite some methods that UserDict just implements inefficiently. 
  This gave me an 8-10% improvement in my performance tests.

* Added a hook for doing a proper object cache later.

  Log Message:
  -----------
  - Performance: Switched to ``repoze.lru`` (from ``lru``), which is much
  faster.

- Performance: To avoid excessive hash computations, we now use the hash of
  the ``DBRef`` references as cache keys.

- Bug: ``ObjectId`` ids are not guarantted to be unique accross
  collections. Thus they are a bad key for global caches. So we use full
  ``DBRef`` references instead.

  Log Message:
  -----------
  The BSON c-code references the bson.dbref.DBRef class directly and that 
reference cannot be replaced. So we are doing our best to overwrite as 
much as possible. The two features are:

* Single, lazy computation of hash.

* Disabling of the arbitrary attribute feature.

The latter just makes several methods much faster, which really matters 
when loading many objects (2-4%).

  Log Message:
  -----------
  - Performance: Improved the profiler a bit by allowing to disable modification
  of records as well.

- Performance: Added caching of ``_m_jar`` lookups in Mongo Containers, since
  the computation turned out to be significantly expensive.

- Performance: Use lazy hash computation for DBRef. Also, disable support for
  arbitrary keyword arguments. This makes roughly a 2-4% difference in object
  loading time.

Get ready for release.

  Log Message:
  -----------
  Bug: Due to ``UserDict`` implementing ``dict`` comparison semantics, any
empty ``MongoContainer`` would equate to another empty one. This behavior
would cause object changes to not be properly recognzed by the mongo data
manager. The implemented solution is to implement default object comparison
behavior for mongo containers.

Get ready for release.

  - Feature: Added ``find_objects()`` and ``find_one_object()``to the collection
  wrapper, so that whenever you get a collection from the data manager, you
  can load objects directly through the find API.

- Feature: Added the ability for MongoContained objects to fully reference and
  load their parents. This allows one to query mongo directly and create the
  object from the doc without going through the right container, which you
  might not know easily
