There are cases where the originating mapper name is not present in the exception message, such as relationship initialization against an unmapped class. Ensure the originating mapper is named in the string output. Pull-request: https://github.com/zzzeek/sqlalchemy/pull/298 Change-Id: I9f23bfa90b26dde9229ab7ec812eec9ceae48153
Fixed bug where setting up a single-table inh subclass of a joined-table subclass which included an extra column would corrupt the foreign keys collection of the mapped table, thereby interfering with the initialization of relationships.

This is an old parameter no longer relevant to how SQLAlchemy works, once the Query object was introduced. By deprecating it we establish that we aren't supporting non-working use cases and that we encourage applications to move off of the use of this parameter. Fixes: #3394 Change-Id: I25b9a38142a1537bbcb27d3e8b66a8b265140072
Fixed bug where in Py2K a unicode literal would not be accepted as the string name of a class or other argument within declarative using :func:`.backref` on :func:`.relationship`. amends commit e6f67f48054d906856f879bc1803ea639aa4b670
"auto increment" column has been changed, such that autoincrement is no longer implicitly enabled for a :class:`.Table` that has a composite primary key. In order to accommodate being able to enable autoincrement for a composite PK member column while at the same time maintaining SQLAlchemy's long standing behavior of enabling implicit autoincrement for a single integer primary key, a third state has been added to the :paramref:`.Column.autoincrement` parameter ``"auto"``, which is now the default. fixes #3216 - The MySQL dialect no longer generates an extra "KEY" directive when generating CREATE TABLE DDL for a table using InnoDB with a composite primary key with AUTO_INCREMENT on a column that isn't the first column; to overcome InnoDB's limitation here, the PRIMARY KEY constraint is now generated with the AUTO_INCREMENT column placed first in the list of columns.
a column setup on the ABC base which had a different attribute name vs. column name would not be correctly mapped on the final base class. The failure on 0.9 would be silent whereas on 1.0 it raised an ArgumentError, so may not have been noticed prior to 1.0. fixes #3480
event where its invocation was moved to be after the class manager's instrumentation of the class, which is the opposite of what the documentation for the event explicitly states. The rationale for the switch was due to Declarative taking the step of setting up the full "instrumentation manager" for a class before it was mapped for the purpose of the new ``@declared_attr`` features described in :ref:`feature_3150`, but the change was also made against the classical use of :func:`.mapper` for consistency. However, SQLSoup relies upon the instrumentation event happening before any instrumentation under classical mapping. The behavior is reverted in the case of classical and declarative mapping, the latter implemented by using a simple memoization without using class manager. fixes #3388
and ``__declare_last__`` accessors where these would no longer be called on the superclass of the declarative base. fixes #3383
