[caldav] Binding always uses old entries from Google calender

Bredmich · January 8, 2019, 8:51am

Ok good to know.
I thought there should be a range of 10 days (for my configuration with 10 days preloadTime).

Could you may answer some questions/correct my assumptions regarding how the binding works.

The binding import all events from a given calender (past and future)
Afterwards it´s checking for events that are between now and the preloadTime
The first events will be stored and marked as eventNr:1
reloadInterval is the time between checks if there´s a new entry that wasn´t imported yet
How does the binding decide when to change the item to a new entry?
Then last thing is what´s currently not working as i think it should. The item is still at an old entry and the binding doesn´t load the next one as eventNr:1

kind regards
Michael

Based on what I’ve seen from using the binding, the first 4 bullets are true.
Generally I think past events are not loaded, but processed and skipped as historic.

The default preloadTime is 24 hours.

As an example, this refresh occurred at 23:17, and loaded events from 23:17 to 24 hours later:

2019-01-06 23:17:23.834 [DEBUG] [caldav.internal.job.EventReloaderJob] - loading events from file : etc\caldav\myCalendar\040000008200E00074C5B7101A82E0080000000050FA8BBB6CF1D101000000000000000010000000E7F6B6DF4F745149822E52A6B3266926.ics

2019-01-06 23:17:23.934 [TRACE] [caldav.internal.job.EventReloaderJob] - loadTo = 2019-01-07T23:17:23.934-05:00

As to bullet 5, items should change when the scheduled event jobs are fired:

2019-01-06 23:17:30.377 [DEBUG] [.io.caldav.internal.CalDavLoaderImpl] - begin timer scheduled for event '50b9kr6mu1cqjtpkm9rofl6srt@google.com(We 3 kings@07.01.2019/10:00-07.01.2019/10:30)' @ Mon Jan 07 10:00:00 EST 2019

So an event should become current when it’s begin timer job runs.

Bredmich · January 8, 2019, 12:58pm

Thanks for you explanation.
Let´s see what happens on 01-10-2019 when the entry should change to the next event.

moodsta · January 9, 2019, 8:16pm

I think I had the same issue as you. When I changed the item file in editor and saved it, the items got updated. I tried out a couple of things and I assume that it is working fine now for me. Only thing I did is to add the calender into the caldavPersonal.cfg file

Looks like this for me:


# Which calendars should be used to detect presence (comma separated)
caldavPersonal:usedCalendars=Muellkalender

Maybe I am wrong but maybe you can give it a try?

Bredmich · January 9, 2019, 8:30pm

I already have this entry in my caldavpersonal.cfg
Thanks for the hint!

Today is an event day, so let´s see if the event changes tomorrow…
I had some sardine errors today for an event at 07-02-2019

The caldav binding changed the event today

I´ve no idea what solved the issue…

moodsta · January 10, 2019, 8:51pm

whoop whoop. Same for me. It’s Biomüll day

Bredmich · January 15, 2019, 5:09pm

Guess what?
After rebooting the Pi the binding stopped working again or mapdb wasn´t able to restoreOnStartup the items.

Why is mapdb not able to restore the state properly?
It´s just a String item.

Bredmich · January 15, 2019, 5:58pm

Ok i´m out of ideas and going to uninstall caldav.
I´m not willing to spend anymore time with this binding.

It´s not loading any event from the calender and not even doing anything like the binding is freezed.
When trying to restart the bundle i just get a tone of errors and the status stays in Waiting
