cache webcal calendars on server by georgehrke · Pull Request #10059 · nextcloud/server

ToDos:

adapt refresh cycle to refresh rate of subscription
- this could actually be tricky. the interval set in the constructor is called before run, but we only know the corresponding subscription when we know the arguments for run
- we can obviously keep track of the last actual update ourself and just run the job once an hour, but I'd prefer if IJobList could just handle that.
update subscription in database when remote returns 301
unit tests

@georgehrke I'd say for now just write a small abstraction class yourself to solve the extra check issue.
Then if it turns out to work corectly etc we can always merge it back to the server part

Most likely nothing for 14 -> moving to 15.

+			if ($calendarObjectsTable->hasIndex('calobjects_index')) {
+				$calendarObjectsTable->dropIndex('calobjects_index');
+			}
+			$calendarObjectsTable->addUniqueIndex(['calendarid', 'calendartype', 'uri'], 'calobjects_index');


@nickvergessen Will building new indices be an issue? Should it be outsourced to a migration step?

I think for this it is fine. Should be relatively fast.

However, a step first to see if there are duplicated might be needed.
As else it will just explode

It removes the old index consisting of calendarid, uri and creates a new index calendarid, calendartype, uri. And calendartype is the all new column that was introduced by the same migration and set to 0 for all existing entries. So there should be no duplicates.

Ah right. :) Carry on then

@rullzer I was generally not sure what's the cleanest / best approach here.
We have calendars and subscriptions in different tables: calendars respectively calendarsubscriptions. This was no issue so far since we didn't store objects related to subscriptions.

So basically there are two options

Have duplicate tables of calendarchanges, calendarobjects and calendarobjects_props for subscriptions

Introduce calendartype that indicates whether calendarid refers to the calendars or the subscriptions table.

I'm fine with both ways - even if the second one would be cleaner you need to update all the existing queries, right?

Yes, i guess the big question here is whether introducing the new column calendartype is reducing performance of day-to-day queries.

When it is used in queries just add an index to it and it should be fine.

@tcitworld Can you please test? Are there any other remarks? :)

The acceptance test results are unrelated.

The phan thing seems to be a faulty php-doc in Sabre/Dav.

georgehrke · 2018-11-07T10:21:12Z

Should I just use @phan-suppress-next-line?

georgehrke · 2018-11-07T10:27:17Z

Just wanted to send a pull-request, but it's already fixed upstream: https://github.com/georgehrke/vobject/blob/master/lib/Splitter/ICalendar.php#L86

blizzz · 2018-11-07T10:29:29Z

@georgehrke is the upstream released and reasonable to get this in? Otherwise, let's suppress it with a note/issue to remove the suppression once we pull again.

georgehrke · 2018-11-07T10:31:15Z

The fix was not released yet, adding @phan-suppress-next-line ...

georgehrke · 2018-11-07T10:52:20Z

@MorrisJobke How to update phan?
We are running phan 0.11.1, but I need 0.12.9 to be able to use @phan-suppress-next-line

blizzz · 2018-11-07T11:03:40Z

@georgehrke try to push https://github.com/nextcloud/server/blob/master/.drone.yml#L104

When int $subscriptionId works for bigint colums i would use it here.

I accidentally stumpled accross this when debugging an abnormality with my script calcardbackup and noticed that this is not in the changelog for Nextcloud 15

This commit adds events with the same calendarid belonging to different calendars ("regular" calendars and "subscribed" calendars). To determine to which calender the events belong there is a new database field calendartype added.

All this are quite big changes which are definitely worth to be mentioned in the changelog. Could this new featur please be added to the changelog?
