Change autoincrement compileerror to a warning

2016-10-07T13:54:39+00:00

Users are complaining that IntegrityError is no longer
raised.

Check for __clause_element__() in ORM insert/update

2016-10-05T16:11:53+00:00

ORM attributes can now be assigned any object that is has a
``__clause_element__()`` attribute, which will result in inline
SQL the way any :class:`.ClauseElement` class does.  This covers other
mapped attributes not otherwise transformed by further expression
constructs.

As part of this, it was considered that we could add
__clause_element__() to ClauseElement, however this causes endless loops
in a "while" pattern and this pattern has been identified in third
party libraries.  Add a test to ensure we never make that change.

Check row for None with implicit returning PK to accommodate ON CONFLICT

2016-10-04T21:31:40+00:00

An adjustment to ON CONFLICT such that the "inserted_primary_key"
logic is able to accommodate the case where there's no INSERT or
UPDATE and there's no net change.  The value comes out as None
in this case, rather than failing on an exception.

Merge "Enhance "raise" strategy to include "raise_on_sql" option"

2016-10-04T20:48:08+00:00

Enhance "raise" strategy to include "raise_on_sql" option

2016-10-04T16:09:29+00:00

The "raise_on_sql" option differentiates from "raise" in that
firing a lazy loader is OK as long as it does a simple
get from identity map.   Whereas "raise" is more useful
for the case that objects are to be detached.

As part of this, refactors the strategy initiation logic
a bit so that a LoaderStrategy itself knows what "key" was used
to create it, thus allowing variants of a single strategy
based on what the "lazy" argument is.  To achieve this we
have to also get rid of _get_strategy_by_cls().

Everything here is internal with the one exception of an apparently
undocumented, but not underscored, "strategy_class" key
on relationship().   Though it's not clear what
"strategy_class" accomplishes; at this point the strategy
system is extensible using Property.strategy_for().

Honor additional row coming in with value of None

2016-10-04T16:07:08+00:00

The change in #3431 still checks that the instance() is
non-None, deferring to other loading schemes if it is.
These columns are dedicated towards the entity however, so if the value
is None, we should set it.  If it conflicts, we are detecting that
in any case.

Ensure strong ref to obj before calling persistent_to_deleted, others

2016-10-03T16:25:42+00:00

Add checks in spots where state.obj() might be late-GC'ed before
we get a chance to call the event.   There may be more cases
of these which we should address as they come up.  The Session
should always be maintaining strong refs to objects that have
pending operations left on them, so for these cases we need
to ensure that ref remains long enough for the event to be called.
