V1.3.0

Notable changes

• Many dependencies, both frontend and backend, were updated.

New Features

• "Download All" attachments button was added to generate and download a zip file of all student submitted answer attachments. This can be found in an assignment's "Participation" tab under the "Attachments" column.
• The "Assignment End-Date" tool was added for admin users to query for the assignments end-date.
  • The purpose of this page is to search for ongoing or active assignments on a given date, to help plan potential schedules for testing, staging, and production environments.

New Environment Variables: For controlling worker memory leak

• CELERY_WORKER_MAX_TASKS_PER_CHILD - Kills a worker process and forks a new one when it has executed the given number of tasks.

• CELERY_WORKER_MAX_MEMORY_PER_CHILD - Set to memory in kilobytes. Kills a worker process and forks a new one when it hits the given memory usage, the currently executing task will be allowed to complete before being killed.

Breaking Changes

Celery 4 introduced a new all lowercase environment variables system. ComPAIR
is now using this new system. To adapt a Celery environment variable to
ComPAIR, convert the original Celery variable to all uppercase and prefix it
"CELERY_". ComPAIR will strip the prefix and lowercase the variable before
passing it to Celery. A few Celery environment variables were renamed in the
new system, the ones supported in ComPAIR are:

• CELERY_ALWAYS_EAGER is now CELERY_TASK_ALWAYS_EAGER
  • Set to true if running stock standalone, see compair/settings.py.
  • Set to false if running via repo's docker-compose.yml
• BROKER_TRANSPORT_OPTIONS is now CELERY_BROKER_TRANSPORT_OPTIONS
• CELERYBEAT_SCHEDULE is now CELERY_BEAT_SCHEDULE
