Just like `OrderByList` the `ExpressionList` expression used to wrap
`Window.partition_by` must implement `get_group_by_cols` to ensure the
necessary grouping when mixing window expressions with aggregate
annotations is performed against the partition members and not the
partition expression itself.
This is necessary because while `partition_by` is implemented as
a source expression of `Window` it's actually a fragment of the WINDOW
expression at the SQL level and thus it should result in a group by its
members and not the sum of them.
Thanks ElRoberto538 for the report.
The gc.set_threshold() call was made conditional to non-PyPy
implementations. The method is not available in PyPy3, and GC is much
less aggressive there, so the adjustment probably is not necessary.
bf.errors returns an ErrorList. Access this directly and avoid creating
a new instance in BaseForm.get_context()
Calling str() on the ErrorList can also be deferred to when the
variable used in the template.
While no code is directly exercising get_refs in a way that triggers
a crash some expressions such as Window stash None in source_expressions
which can obscure the origin of some bugs.
Handling None values like we do in other source_expression traversing
methods such as .contains_aggregates ensures we don't run into surprises
in the future where get_refs() might be used for a different purpose.
Adjustments made to solve_lookup_type to defer the resolving of
references for summarized aggregates failed to account for similar
requirements for lookup values which can also reference annotations
through Aggregate.filter.

Thanks Sergey Nesterenko for the report.
This adds aria-describedby for widgets rendered in a fieldset such as
radios. aria-describedby for these widgets is added to the <fieldset>
element rather than each <input>.
`id_for_label` is blank for widgets with multiple inputs such as radios
and multiple checkboxes. Therefore , `help_text` for fields using these
widgets cannot currently be associated using `aria-describedby`.
`id_for_label` is being used as a guard to avoid incorrectly adding
`aria-describedby` to those widgets.
This change uses `auto_id` as the unique identified for the fields
`help_text`. A guard is added to avoid incorrectly adding
`aria-describedby` to inputs by checking the widget's `use_fieldset`
attribute. Fields rendered in a `<fieldset>` should have
`aria-describedby` added to the `<fieldset>` and not every `<input>`.
On SQLite < 3.39, this forces a GROUP BY clause with a HAVING clause
when no grouping is specified.
