Using mysql Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (x86_64) using readline 6.1

Running in --pair mode against text.TextTests.test_cookie_date to make the tests run in an acceptable time

The test doesn't fail in isolation:

It does in pair mode:

tests % PYTHONPATH=.. ./runtests.py --settings=test_mysql --pair text.TextTests.test_cookie_date

Ran the tests manually now and get the following:

jenkins@pony:~/jobs/Django/workspace/database/mysql/python/python2.6/tests$ python runtests.py --settings=test_mysql comment_tests --pair text.TextTests.test_cookie_date

only seems to fail in pairing mode

comment:5 by Jannis Leidel, 13 years ago

Seems like a caching issue to me, running the postgres tests gives me the same:

comment:6 by Ramiro Morales, 13 years ago

One extradata point:

I see this only when using the MyISAM MySQL storage backend (and using the --pair text.TextTests.test_cookie_date trick). Inserting prints of connection.queries show that the SQL queries are:

SELECT `comment_tests_article`.`id`, `comment_tests_article`.`author_id`, `comment_tests_article`.`headline` FROM `comment_tests_article` WHERE `comment_tests_article`.`id` = 1 
SELECT `django_content_type`.`id`, `django_content_type`.`name`, `django_content_type`.`app_label`, `django_content_type`.`model` FROM `django_content_type` WHERE (`django_content_type`.`model` = 'article'  AND `django_content_type`.`app_label` = 'comment_tests' )

The second query is the problematic one.

Resolution: → wontfix
Status: new → closed

Marking as won't fix in light of no recent activity and the fact that contrib.comments is deprecated.
