- Update to 0.7.6
 * orm
  - [bug] Fixed event registration bug
    which would primarily show up as
    events not being registered with 
    sessionmaker() instances created
    after the event was associated
    with the Session class.  [ticket:2424]

  - [bug] Fixed bug whereby a primaryjoin
    condition with a "literal" in it would
    raise an error on compile with certain
    kinds of deeply nested expressions
    which also needed to render the same
    bound parameter name more than once.
    [ticket:2425]

  - [feature] Added "no_autoflush" context
    manager to Session, used with with:
    will temporarily disable autoflush.

  - [feature] Added cte() method to Query,
    invokes common table expression support
    from the Core (see below). [ticket:1859]

  - [bug] Removed the check for number of
    rows affected when doing a multi-delete
    against mapped objects.   If an ON DELETE
    CASCADE exists between two rows, we can't
    get an accurate rowcount from the DBAPI;
    this particular count is not supported
    on most DBAPIs in any case, MySQLdb
    is the notable case where it is.
    [ticket:2403]

  - [bug] Fixed bug whereby objects using
    attribute_mapped_collection or 
    column_mapped_collection could not be
    pickled.  [ticket:2409]

  - [bug] Fixed bug whereby MappedCollection
    would not get the appropriate collection
    instrumentation if it were only used
    in a custom subclass that used
    @collection.internally_instrumented.  
    [ticket:2406]

  - [bug] Fixed bug whereby SQL adaption mechanics
    would fail in a very nested scenario involving
    joined-inheritance, joinedload(), limit(), and a
    derived function in the columns clause.  
    [ticket:2419]

  - [bug] Fixed the repr() for CascadeOptions to
    include refresh-expire.  Also reworked
    CascadeOptions to be a <frozenset>.
    [ticket:2417]

  - [feature] Added the ability to query for
    Table-bound column names when using 
    query(sometable).filter_by(colname=value).  
    [ticket:2400]

  - [bug] Improved the "declarative reflection" 
    example to support single-table inheritance,
    multiple calls to prepare(), tables that
    are present in alternate schemas,
    establishing only a subset of classes
    as reflected.

  - [bug] Scaled back the test applied within
    flush() to check for UPDATE against partially 
    NULL PK within one table to only actually 
    happen if there's really an UPDATE to occur.
    [ticket:2390]

  - [bug] Fixed bug whereby if a method name
    conflicted with a column name, a
    TypeError would be raised when the mapper
    tried to inspect the __get__() method
    on the method object.  [ticket:2352]

 * sql
  - [bug] Fixed memory leak in core which would
    occur when C extensions were used with
    particular types of result fetches,
    in particular when orm query.count()
    were called.  [ticket:2427]

  - [bug] Fixed issue whereby attribute-based
    column access on a row would raise 
    AttributeError with non-C version,
    NoSuchColumnError with C version.  Now
    raises AttributeError in both cases.
    [ticket:2398]

  - [feature] Added support for SQL standard
    common table expressions (CTE), allowing
    SELECT objects as the CTE source (DML
    not yet supported).  This is invoked via
    the cte() method on any select() construct.
    [ticket:1859]

  - [bug] Added support for using the .key
    of a Column as a string identifier in a 
    result set row.   The .key is currently
    listed as an "alternate" name for a column,
    and is superseded by the name of a column 
    which has that key value as its regular name.
    For the next major release
    of SQLAlchemy we may reverse this precedence
    so that .key takes precedence, but this
    is not decided on yet.  [ticket:2392]

  - [bug] A warning is emitted when a not-present
    column is stated in the values() clause
    of an insert() or update() construct.
    Will move to an exception in 0.8.
    [ticket:2413]

  - [bug] A significant change to how labeling
    is applied to columns in SELECT statements
    allows "truncated" labels, that is label names
    that are generated in Python which exceed
    the maximum identifier length (note this is 
    configurable via label_length on create_engine()),
    to be properly referenced when rendered inside
    of a subquery, as well as to be present
    in a result set row using their original
    in-Python names.   [ticket:2396]

  - [bug] Fixed bug in new "autoload_replace" flag
    which would fail to preserve the primary
    key constraint of the reflected table.
    [ticket:2402]

  - [bug] Index will raise when arguments passed
    cannot be interpreted as columns or expressions.
    Will warn when Index is created
    with no columns at all.  [ticket:2380]

 * engine
  - [feature] Added "no_parameters=True" execution
    option for connections.   If no parameters
    are present, will pass the statement
    as cursor.execute(statement), thereby invoking
    the DBAPIs behavior when no parameter collection
    is present; for psycopg2 and mysql-python, this
    means not interpreting % signs in the string.
    This only occurs with this option, and not
    just if the param list is blank, as otherwise
    this would produce inconsistent behavior
    of SQL expressions that normally escape percent
    signs (and while compiling, can't know ahead of 
    time if parameters will be present in 
    some cases).  [ticket:2407]

  - [bug] Added execution_options() call to
    MockConnection (i.e., that used with 
    strategy="mock") which acts as a pass through
    for arguments.

  - [feature] Added pool_reset_on_return argument
    to create_engine, allows control over 
    "connection return" behavior.  Also added
    new arguments 'rollback', 'commit', None
    to pool.reset_on_return to allow more control
    over connection return activity. [ticket:2378]

  - [feature] Added some decent context managers
    to Engine, Connection:

        with engine.begin() as conn:
            <work with conn in a transaction>

    and:

        with engine.connect() as conn:
            <work with conn>

    Both close out the connection when done,
    commit or rollback transaction with errors
    on engine.begin().

 * sqlite
  - [bug] Fixed bug in C extensions whereby
    string format would not be applied to a
    Numeric value returned as integer; this
    affected primarily SQLite which does
    not maintain numeric scale settings.
    [ticket:2432]

 * mssql
  - [feature] Added support for MSSQL INSERT, 
    UPDATE, and DELETE table hints, using
    new with_hint() method on UpdateBase.
    [ticket:2430]

 * mysql
  - [feature] Added support for MySQL index and
    primary key constraint types
    (i.e. USING) via new mysql_using parameter
    to Index and PrimaryKeyConstraint, 
    courtesy Diana Clarke.  [ticket:2386]

  - [feature] Added support for the "isolation_level"
    parameter to all MySQL dialects.  Thanks
    to mu_mind for the patch here. [ticket:2394]

 * oracle
  - [feature] Added a new create_engine() flag
    coerce_to_decimal=False, disables the precision
    numeric handling which can add lots of overhead
    by converting all numeric values to 
    Decimal.  [ticket:2399]

  - [bug] Added missing compilation support for 
    LONG [ticket:2401]

  - [bug] Added 'LEVEL' to the list of reserved
    words for Oracle.  [ticket:2435]

 * examples
  - [bug] Altered _params_from_query() function
    in Beaker example to pull bindparams from the
    fully compiled statement, as a quick means
    to get everything including subqueries in the
    columns clause, etc.

-------------------------------------------------------------------
Thu Feb  9 09:39:26 UTC 2012 - rhafer@suse.de

- Update to 0.7.5:
  * Fixed issue where modified session state established after a
    failed flush would be committed as part of the subsequent
    transaction that begins automatically after manual call to
    rollback().
  * Improved the API for add_column() such that if the same column
    is added to its own table, an error is not raised and the
    constraints don't get doubled up.
  * Fixed issue where the "required" exception would not be raised
    for bindparam() with required=True, if the statement were given
    no parameters at all.
  * for more details see the CHANGES file.
