Run handle_error for any exceptions raised in execute_context()

2020-03-04T01:00:07+00:00

Observing a SQLite connection/cursor being hung on
test_resultset -> PositionalTextTest -> test_dupe_col_obj.
this uses connectionless execution and the result object
fails to be constructed.  When that happens, there is no path
for the cursor or connection to be closed / released.
Recent changes with the exception assertions in #4849 seem to
be causing a cycle to last a little longer than usual which
is exposing this issue for one particular test on SQLite.

As we want to get rid of weakref cleanup, evaluate
why we dont have handle_dbapi_exception for this whole
block, as after_cursor_execute can raise, result construction
can raise, autocommit can raise, close can raise, there
does not seem to be a reason these things should be outside
of the block that gets cleaned up.

Restore crud flags if visiting_cte is set

2020-03-03T22:23:56+00:00

Fixed bug where a CTE of an INSERT/UPDATE/DELETE that also uses RETURNING
could then not be SELECTed from directly, as the internal state of the
compiler would try to treat the outer SELECT as a DELETE statement itself
and access nonexistent state.

Remove the deprecated loader options

2020-03-03T21:33:49+00:00

Remove the deprecated loader options ``joinedload_all``, ``subqueryload_all``,
``lazyload_all``, ``selectinload_all``. The normal version with method chaining
should be used in their place.

Ensure all nested exception throws have a cause

2020-03-02T22:24:19+00:00

Applied an explicit "cause" to most if not all internally raised exceptions
that are raised from within an internal exception catch, to avoid
misleading stacktraces that suggest an error within the handling of an
exception.  While it would be preferable to suppress the internally caught
exception in the way that the ``__suppress_context__`` attribute would,
there does not as yet seem to be a way to do this without suppressing an
enclosing user constructed context, so for now it exposes the internally
caught exception as the cause so that full information about the context
of the error is maintained.

Merge "While parsing for check constraints, ignore newline characters in the check condition"

While parsing for check constraints, ignore newline characters in the check condition

2020-02-29T22:45:05+00:00

Fixed bug where PostgreSQL reflection of CHECK constraints would fail to
parse the constraint if the SQL text contained newline characters. The
regular expression has been adjusted to accommodate for this case. Pull
request courtesy Eric Borczuk.
