* Ensure Oracle index w/ col DESC etc. is reflectedMike Bayer2017-08-141-1/+36
| | | | | | | | | | | | | | | | | | | | Fixed bug where an index reflected under Oracle with an expression like "column DESC" would not be returned, if the table also had no primary key, as a result of logic that attempts to filter out the index implicitly added by Oracle onto the primary key columns. Reworked the "filter out the primary key index" logic in oracle get_indexes() to be clearer. This changeset also adds an internal check to ColumnCollection to accomodate for the case of a column being added twice, as well as adding a private _table argument to Index such that reflection can specify the Table explicitly. The _table argument can become part of public API in a later revision or release if needed. Change-Id: I745711e03b3e450b7f31185fc70e10d3823063fa Fixes: #4042

* Check for __module__ not present in util.wrap_callable()Mike Bayer2016-10-141-0/+13
| | | | | | | | | The newly added wrap_callable() function assumes __module__ is present when this is not the case for objects such as functools.partial. Change-Id: Ia226260e9a65419e26d5c1f7187512f7fd4bb7c1 Fixes: #3823
* Repair pickling for Properties objectPieter Mulder2016-06-291-0/+35
| | | | | | | | | | | | | Fixed bug whereby the ``__getstate__`` / ``__setstate__`` methods for sqlalchemy.util.Properties were non-working due to the transition in the 1.0 series to ``__slots__``. The issue potentially impacted some third-party applications. Pull request courtesy Pieter Mulder.

* - Fixed bug in "to_list" conversion where a single bytes objectMike Bayer2016-02-211-1/+15
| | | | | | | would be turned into a list of individual characters. This would impact among other things using the :meth:`.Query.get` method on a primary key that's a bytes object. fixes #3660
* - revert the change first made in a6fe4dc, as we are now generalizingMike Bayer2016-01-281-1/+33
| | | | | | | | | | | | | | | | | | | | | | | the warning here to all safe_reraise() cases in Python 2. - Revisiting :ticket:`2696`, first released in 1.0.10, which attempts to work around Python 2's lack of exception context reporting by emitting a warning for an exception that was interrupted by a second exception when attempting to roll back the already-failed transaction; this issue continues to occur for MySQL backends in conjunction with a savepoint that gets unexpectedly lost, which then causes a "no such savepoint" error when the rollback is attempted, obscuring what the original condition was. The approach has been generalized to the Core "safe reraise" function which takes place across the ORM and Core in any place that a transaction is being rolled back in response to an error which occurred trying to commit, including the context managers provided by :class:`.Session` and :class:`.Connection`, and taking place for operations such as a failure on "RELEASE SAVEPOINT". Previously, the fix was only in place for a specific path within the ORM flush/commit process; it now takes place for all transational context managers as well. fixes #2696
* - Fixed bug where some exception re-raise scenarios would attachMike Bayer2016-01-181-0/+59
| | | | | | | | the exception to itself as the "cause"; while the Python 3 interpreter is OK with this, it could cause endless loops in iPython. fixes #3625 - add tests for reraise, raise_from_cause - raise_from_cause is the same on py2k/3k, use just one function
* Fix _assert_unorderable_types on py36.pr/218Iuri de Silvio2015-11-301-1/+4

* - Fixed an issue where a particular base class within utilsMike Bayer2015-07-201-1/+29
| | | | | | | | | didn't implement ``__slots__``, and therefore meant all subclasses of that class didn't either, negating the rationale for ``__slots__`` to be in use. Didn't cause any issue except on IronPython which apparently does not implement ``__slots__`` behavior compatibly with cPython. Fixes #3494

* - The :meth:`.PropComparator.of_type` modifier has beenMike Bayer2014-11-241-0/+30
| | | | | | | | | | | | | | | improved in conjunction with loader directives such as :func:`.joinedload` and :func:`.contains_eager` such that if two :meth:`.PropComparator.of_type` modifiers of the same base type/path are encountered, they will be joined together into a single "polymorphic" entity, rather than replacing the entity of type A with the one of type B. E.g. a joinedload of ``A.b.of_type(BSub1)->BSub1.c`` combined with joinedload of ``A.b.of_type(BSub2)->BSub2.c`` will create a single joinedload of ``A.b.of_type((BSub1, BSub2)) -> BSub1.c, BSub2.c``, without the need for the ``with_polymorphic`` to be explicit in the query. fixes #3256

* - Some changes to how the :attr:`.FromClause.c` collection behavesMike Bayer2014-02-261-1/+156
| | | | | | | | | | | | | | | | | | | | | | | when presented with duplicate columns. The behavior of emitting a warning and replacing the old column with the same name still remains to some degree; the replacement in particular is to maintain backwards compatibility. However, the replaced column still remains associated with the ``c`` collection now in a collection ``._all_columns``, which is used by constructs such as aliases and unions, to deal with the set of columns in ``c`` more towards what is actually in the list of columns rather than the unique set of key names. This helps with situations where SELECT statements with same-named columns are used in unions and such, so that the union can match the columns up positionally and also there's some chance of :meth:`.FromClause.corresponding_column` still being usable here (it can now return a column that is only in selectable.c._all_columns and not otherwise named). The new collection is underscored as we still need to decide where this list might end up. Theoretically it would become the result of iter(selectable.c), however this would mean that the length of the iteration would no longer match the length of keys(), and that behavior needs to be checked out. fixes #2974 - add a bunch more tests for ColumnCollection
* - Fixed regression where using a ``functools.partial()`` with the eventMike Bayer2014-01-041-1/+30
| | | | | | | | | | | system would cause a recursion overflow due to usage of inspect.getargspec() on it in order to detect a legacy calling signature for certain events, and apparently there's no way to do this with a partial object. Instead we skip the legacy check and assume the modern style; the check itself now only occurs for the SessionEvents.after_bulk_update and SessionEvents.after_bulk_delete events. Those two events will require the new signature style if assigned to a "partial" event listener. [ticket:2905]
