Test suite failures


As Django 1.0, the test suite is showing the following failure(s) when run under Windows (XP 32 bits) + official Python 2.5.2:

  • Ticket #7570 when using the sqlite3 Django DB backend (official Python 2.5.2 Windows distribution which includes SQLite 3.3.4).

ticket #7570

This test (and other two similar tests) fails:

Bug #7087 -- dates with extra select columns
>>> Item.objects.dates('created', 'day').extra(select={'a': 1})
[datetime.datetime(2007, 12, 19, 0, 0), datetime.datetime(2007, 12, 20, 0, 0)] 

Error is:

FAILED (failures=1)

The SQL being generated by Django is correct:

>>> Item.objects.dates('created', 'day').extra(select={'a': 1}).query.as_sql()
('SELECT DISTINCT (1) AS "a", django_date_trunc("day", "sqlite3_dates_item"."created") FROM "sqlite3_dates_item" ORDER BY 1 ASC', ())

The problem has been tracked down to a bug in SQLite in version older than 3.3.6.
