Past Event Limit Behaviour

[rimeraz]

Hi there,

Because CalDAV-sync and CardDAV-sync seem to be orphaned, I recently moved to DAVx5 and so far I really like it. However I have trouble understanding one feature.

With CardDAV-sync I could sync the whole calendar: It distinguished between shorttime sync and longtime sync. This is very useful if you move to a new device and - like me - you want to have a complete calendar on your phone for reference.

Regarding past event sync, the DAVx5 manual says:

Older events won’t be synchronized and won’t show up in the calendar anymore. An empty value means that all events will be synchronized.

I could manage to sync my two calendars completely by removing the values from Past Event Time Limit in both accounts. So far so good.

Also, the app says (at least in German, corresponding English translation by me) for Past Event Time Limit seting:

Events more than 90 days in the past will be ignored.

However if I add the default 90 days again after syncing the whole calendar, with next sync all my events older than 90 days disappear again. But they have already been synchronized so I would not expect that they will be touched again by sync. App says they would be ignored.

Neither app nor the manual state anything regarding removing events from local calendar beyond that time limit.

Is this expected? Does the app actually keep only events now()-90d until future locally? I couldn't find anything here in the discussions and wonder if the only way to permanently keep a complete calendar is to remove the value for Past Event Time Limit.

Could anybody please shed some light on me?

Hello,

Yes, this is expected. Every sync will fetch a list of all events in the specified time window from the server and then synchronize them with the local storage. Older events are treated like they would have been deleted on the server and are also deleted locally. This helps with scaling - so you don't have events older than you need that clutter your device and take space.

Could when have an sync on 90 days but not removing previous locally stored events? So once a while I can run a full sync and other time just a 90 days sync and I always see all my events.

It could be an option ¨See previously sync older events".

Note: after tries, my sync of all events is not too long, therefore I can keep full sync each time.

On the same setting I have the problem, that it seems to still sync only the last 90 days if I leave it empty. If I enter e.g. 9999 it syncs older events just finde.

This question may be dumb, but: where do I find the "past event time limit" setting in DAVx5? (Android 13 on Google Pixel 5, DAVx5 Version 4.3.5-gplay)

My events for the past year show up in my calendar, older events are not synced (but exist on my nextcloud). I want to change this.

I only have 1 account. Clicking on it there is the gearwheel (preferences) and the three dots (new adress book, new account etc.) next to it. On neither of these I can find this setting.
I can also switch to the CALDAV tab, choose the three dots next to my calendar, choose Preferences and I only see my URL, owner and last synced.

What am I doing wrong?

Yes, it's there (you probably have to scroll down in the settings)

Thanks for your quick reply! So you mean the window seen on the attached screenshot? Nothing to scroll there.

Seems you are affected by a rare migration bug to 4.3.4. Please remove the account and add it again with the latest DAVx5 version (4.3.5). The settings should be complete and it shouldnt happen again.

Thanks a lot, this worked!

[akoyaxd]

Oh, that makes sense! I use nextcloud as a server. There doesn't seem to be a setting for this though...

Thanks for clearing that up.

Nextcloud normally can perfectly deal with either the "Filter" method (when putting a number into the field) or also with the "Collection sync" method when the field is empty (=so that everything is transferred)...

[akoyaxd]

Hmm. I can definitely say, that this is not the case for me on Nextcloud 24.0.2.

[rfc2822]

Maybe there's some other problem? You can however see the request the is sent to Nextcloud (should be REPORT + filter when past time event limit is set, PROPFIND otherwise) + its reply in the verbose logs (DAVx5 / Settings / Logs).
