|
|
* The quota is requested if these 3 conditions are met:
|
|
* - This object is active via setActive() (typically if the settings page is visible.)
|
|
* - The account is connected.
|
|
* - Every 30 seconds (defaultIntervalT) or 5 seconds in case of failure (failIntervalT)
|
|
*
|
|
* We only request the quota when the UI is visible otherwise this might slow down the server with
|
|
* too many requests. But we still need to do it every 30 seconds otherwise user complains that the
|
|
* quota is not updated fast enough when changed on the server.
|
|
*
|
|
* If the quota job is not finished within 30 seconds, it is cancelled and another one is started
