Change course schedule update mechanism #32

Closed arielmiki closed 4 years ago

arielmiki commented 5 years ago

This issue is a:

Current behavior:

I see that currently, course schedule is updated using flask cron cli command. I don't know if this is triggered manually or using a scheduler in the server (I don't know if it is correct because I am not familiar with flask cron). At least, that is what I can conclude when seeing this. However, recent course update from SIAK is not reflected by Susun Jadwal.

Requested behavior:

Maybe, we can use in-memory cache and give it TTL, so users always get the most updated schedule. Besides, I think we also need to make update_courses function is able to update the schedule for each major separately. BTW, I don't know if it is possible.

Why this behavior is better:

Courses that stop being updated means that either the cron has stopped or the scraper's SSO has been changed. For compsci it should still be fine tho (it uses mine). @albadrun Any comment?

Currently, the scheduler is set once per hour, so maybe the schedule in SIAK is updated in the last hour. I think the cache solution is basically equivalent to the scheduler with TTL 1 hour. I believe the solution is to run the scheduler more frequently.

Closing this as we update the cron job readme. The frequency is subject to discussion of the active maintainers.
