Description: ============
        Transactions
        ============
        
        This package contains a generic transaction implementation for Python. It is
        mainly used by the ZODB, though.
        
        Note that the data manager API, ``transaction.interfaces.IDataManager``,
        is syntactically simple, but semantically complex.  The semantics
        were not easy to express in the interface. This could probably use
        more work.  The semantics are presented in detail through examples of
        a sample data manager in ``transaction.tests.test_SampleDataManager``.
        
        
        Changes
        =======
        
        1.1.1 (2010-09-16)
        ------------------
        
        Bug Fixes:
        
        - Code in ``_transaction.py`` held on to local references to traceback
        objects after calling ``sys.exc_info()`` to get one, causing
        potential reference leakages.
        
        - Fixed ``hexlify`` NameError in ``transaction._transaction.oid_repr``
        and add test.
        
        1.1.0 (1010-05-12)
        ------------------
        
        New Features:
        
        - Transaction managers and the transaction module can be used with the
        with statement to define transaction boundaries, as in::
        
        with transaction:
        ... do some things ...
        
        See transaction/tests/convenience.txt for more details.
        
        - There is a new iterator function that automates dealing with
        transient errors (such as ZODB confict errors). For example, in::
        
        for attempt in transaction.attempts(5):
        with attempt:
        ... do some things ..
        
        If the work being done raises transient errors, the transaction will
        be retried up to 5 times.
        
        See transaction/tests/convenience.txt for more details.
        
        Bugs fixed:
        
        - Fixed a bug that caused extra commit calls to be made on data
        managers under certain special circumstances.
        
        https://mail.zope.org/pipermail/zodb-dev/2010-May/013329.html
        
        - When threads were reused, transaction data could leak accross them,
        causing subtle application bugs.

        1.0.1 (2010-05-07)
        ------------------
        
        - LP #142464:  remove double newline between log entries:  it makes doing
        smarter formatting harder.
        
        - Updated tests to remove use of deprecated ``zope.testing.doctest``.
        
        1.0.0 (2009-07-24)
        ------------------
        
        - Fix test that incorrectly relied on the order of a list that was generated
        from a dict.
        
        - Remove crufty DEPENDENCIES.cfg left over from zpkg.
        
        1.0a1 (2007-12-18)
        ------------------
        
        = Initial release, branched from ZODB trunk on 2007-11-08 (aka
        "3.9.0dev").
        
        - Remove (deprecated) support for beforeCommitHook alias to
        addBeforeCommitHook.
        
        - Add weakset tests.
        
        - Remove unit tests that depend on ZODB.tests.utils from
        test_transaction (these are actually integration tests).
