Don't use repr() for Column/ColumnClause in warning

2017-09-11T03:08:30+00:00

for #4073, use the string version of the column expression
in the warning, otherwise the repr() is showing the hex id
which causes unlimited warnings.

Warn instead of raise for unmapped column that matches on key

2017-09-10T04:01:18+00:00

Modified the change made to the ORM update/delete evaluator in
:ticket:`3366` such that if an unmapped column expression is present
in the update or delete, if the evaluator can match its name to the
mapped columns of the target class, a warning is emitted, rather than
raising UnevaluatableError.  This is essentially the pre-1.2 behavior,
and is to allow migration for applications that are currently relying
upon this pattern.  However, if the given attribute name cannot be
matched to the columns of the mapper, the UnevaluatableError is
still raised, which is what was fixed in :ticket:`3366`.

Remove LRU warnings

2017-09-09T01:42:07+00:00

Removed the warnings that are emitted when the LRU caches employed
by the mapper as well as loader srtategies reach their threshold; the
purpose of this warning was at first a guard against excess cache keys
being generated but became basically a check on the "creating many
engines" antipattern.   While this is still an antipattern, the presense
of test suites which both create an engine per test as well as raise
on all warnings will be an inconvenience; it should not be critical
that such test suites change their architecture just for this warning
(though engine-per-test suite is always better).

Merge "Guard against KeyError in session.merge after check for identity"

Guard against KeyError in session.merge after check for identity

2017-09-04T23:37:34+00:00

Fixed bug in :meth:`.Session.merge` following along similar lines as that
of :ticket:`4030`, where an internal check for a target object in
the identity map could lead to an error if it were to be garbage collected
immediately before the merge routine actually retrieves the object.

Check for non-mapped property in synonym

2017-09-04T22:55:30+00:00

An :class:`.InvalidRequestError` is raised when a :func:`.synonym`
is used against an attribute that is not against a :class:`.MapperProperty`,
such as an association proxy.  Previously, a recursion overflow would
occur trying to locate non-existent attributes.

Always check that discarded state is the expected one

2017-09-04T20:22:29+00:00

Fixed race condition in ORM identity map which would cause objects
to be inappropriately removed during a load operation, causing
duplicate object identities to occur, particularly under joined eager
loading which involves deduplication of objects.  The issue is specific
to garbage collection of weak references and is observed only under the
Pypy interpreter.

Consider merge key with (None, ) as non-persistent

2017-08-31T21:21:35+00:00

Fixed bug in :meth:`.Session.merge` where objects in a collection that had
the primary key attribute set to ``None`` for a key that is  typically
autoincrementing would be considered to be a database-persisted key for
part of the internal deduplication process, causing only one object to
actually be inserted in the database.

Additional fixes to sane rowcount

for post_update as well as deletes.
