Public bug reported:
Mahara: 16.04.2
DB: Postgres
OS: Linux
Browser: various
File quota calculations are not syncing correctly for file upload when
using multiple devices at the same time.
This lets users surpass their quota by using different computers at the
same time.
I've also been able to replicate it by uploading multiple files at once.
The usr.quotaused field doesn't get correctly accumulated after each
file as it gets overwritten by the other file getting loaded. Perhaps a
transaction is required?
The cron job at the end of the day calculates the quota correctly but by
then, the user has uploaded many times more than their quota
For example, we were getting numbers such as 244% of their 500MB quota.
