I wanted to make a byte-sized contribution but there were no Jira tickets so we decided, thanks to a conversation with @jmbowman through the Open Edx Community #incr (Slack) channel, to collaborate in the elimination of warnings listed in the Warnings Report at https://build.testeng.edx.org/job/edx-platform-python-pipeline-master/warning_5freport_5fall_2ehtml/ This PR contributes to the elimination of RemovedInDjango30Warnings, specifically the one mentioned above and reported in the Warnings Report Changed cookie_date to http_date in the following file: openedx/core/djangoapps/user_authn/cookies.py This warning occurs due to deprecation since Django 2.1: https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.cookie_date
Open edX -------- This is the root package for Open edX. The intent is that all importable code from Open edX will eventually live here, including the code in the lms, cms, and common directories. If you're adding a new Django app, place it in core/djangoapps. If you're adding utilities that require Django, place them in core/djangolib. If you're adding code that defines no Django models or views of its own but is widely useful, put it in core/lib. Note: All new code should be created in this package, and the legacy code will be moved here gradually. For now the code is not structured like this, and hence legacy code will continue to live in a number of different packages.
