Comment (by Tom Forbes):
PR for window function failures:
https://github.com/django/django/pull/10228
I've not had much experience with window expressions, but after doing some
exploration it seems MariaDB has a few annoying quirks. Firstly the
results of a query that uses window functions are not implicitly ordered,
so the ordering has to be repeated. All examples in the MariaDB KB show
this: https://mariadb.com/kb/en/library/window-functions-overview/. For
these tests I just added a conditional `.order()` call if it's MariaDB.
Secondly 'RANGE' frames have a limitation that's not present in other
databases (https://jira.mariadb.org/browse/MDEV-11747). For this I just
adapted the test to work around this limitation.
And lastly `LEAD` and `LAG` have no `default` parameter
(https://jira.mariadb.org/browse/MDEV-12981). I just skipped these tests.
The PR needs more work done before it's ready, but if I don't have time I
thought I would share what I've got so far for anyone else to pick up.
Tests pass locally with MariaDB 10.3.
