"Sync Now" should synchronize "meta" database when pressed

[mrsarm]

What feature do you want to improve?
When users press "Sync Now" , only the device's main database is synchronized (the database with the reports, tasks, messages..). The "meta" database that contains feedback and telemetry documents is only synchronized by a cron job each 30 min, and if there is no connection by the time, another 30 min of waiting are needed to successfully synchronize.

Describe the improvement you'd like
When user clicks "Sync Now", the meta DB should also be synchronized. One synchronization shouldn't affect the sync of the another.

Describe alternatives you've considered
This was not requested by any particular partner or user, but would be a nice to have now that we are increasing the quality and sync frequency of "meta" data. Also is a one line patch, that going to attach to the issue.

Additional context
The size of the request needed to do the synchronization is still little data, it won't affect data caps if the data is synchronized with a mobile data plan instead of WiFi, because taking into account compression used by the devices and that only new data is syncronized, only a few kilobytes are consumed. Moreover, because we put the user in control of when to synchronize, we avoid waste of data spend by requests made automatically by the app because the user can choose to do the sync when is connected to a WiFi connection.

Ready for AT, PR #7122 , branch sync-now-meta.

Testing

This is how I tested locally the changes:

1. Login with any user either from a desktop browser or the app, and do some clicks to let the app record some telemetry and then logout.
2. Change the time of the device to next day. Go back to the app, and do some more clicks.
3. Check the user meta database of the user, e.g. if the username is mariano, the db is medic-user-mariano-meta. It should have a bunch of telemetry-YEAR-MONTH-DAY-mariano-RANDOMUUID records, but not yet a record from the current date. E.g. the current day is Sep 15 2021 and you moved the clock to Sep 16 2021, but you shouldn't have yet a record with the _id telemetry-2021-9-15-mariano-RANDOMUUID.
4. Login again, and check the DB (without logout). Still you don't have the telemetry record for Sep 15.
5. Click the Hamburger menu > "Sync now".
6. Ceck again the DB, now you should see the record for Sep 15.

Tested logging bugs don't sync with other docs but sync on Sync Now
Tested using the test page and generating feed back docs. Syncs on the Sync now button or app refreshed and sync occurs naturally.

@mrsarm does this require a one day lag period for telemetry?

Logged in as a new offline user.
Have a bunch of telemetry docs on my local storage.
Click sync now.
No telemetry is synced.

does this require a one day lag period for telemetry?

@newtewt yes because what are synchronized are the records from previous days (summarized in one record each day). Step 2 here suggests to change the clock time one day forward.

Also not mention because it's unlikely: sentinel moves each XX time records from each user's meta DB to the medic-users-meta database. If you don't find the record in the user's meta, checkout the other, or just stop sentinel while doing the test.

Cool, just thought it to be odd that sync now still requires a daily cycle process to sync now.

After adjusting my date the telemetry logged.

I think this is working as expected and we can move on.

Yes I myself got the same confusion testing the change 😄
