Timeout problems - syncing contacts

DAVx⁵

Hello
I’m running owncloud 10.0.0.4 on a slow system and requesting a contact sync >450 entries (with pictures).
As far as i’m able to judge the client is requesting the whole addressbook and after timeout exception it want to retry a request of 10 entries. At this time the server is still running at 100% cpu duty collecting the previous request.
That leads to a bunch of apache instances on server-side which freezes the system for a couple of minutes and the client isn’t getting it’s requests within it’s (too short and unconfigurable) timeout.
For reference: setting the timeout to 180sec would very likely fix this problem

So the issue indeed seems to be with Android 7 in some way, depending on how you configured your server, I’ll just copy a github comment i accidentally made to the wrong place.

I can confirm that the f-droid version was affected, the offending nginx config is this:
ssl_ecdh_curve secp384r1;

other relevant ssl config lines:

ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers “EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH”;
ssl_ecdh_curve secp384r1;
ssl_session_cache shared:SSL:50m;
ssl_session_timeout 5m;
ssl_session_tickets off;
ssl_stapling on;
ssl_stapling_verify on;

So with that option commented out it’s working fine, I’m on 1.6.1.1-ose from f-droid and android 7.

Apparently Android 7 supports only up to secp256r1, this was supposedly fixed in 7.1.1.

Aside that, a bit of a rant, why are gitlab issues not enabled and instead this forum is used as a bug report tool? I have to create yet another account and wade through 5 google captchas just to write this.

I experience a similar issue with several public Google calendars. However, it’s not unique to ICSx5, but happens on other clients too, including Mozilla Thunderbird and Mailfence. Basically, what I am observing is the following:

On adding the calendar, the client is generally able to fetch all events. But on subsequent tries to refresh, it fails.

A public Google calendar (https://calendar.google.com/calendar/ical/aikfotboll2019%40gmail.com/public/basic.ics) that I have subscribed to for several months sporadically fails with the infamous error “failed to connect to calendar.google.com …”. However, I have reason to believe that it occasionally succeeds, because there are events in my calendar that I don’t think were there at the time of subscribing.

An hour ago, I tried adding another public Google calendar (https://calendar.google.com/calendar/ical/sv.swedish%23holiday%40group.v.calendar.google.com/public/basic.ics) to Thunderbird. Again, adding it succeeded, and events showed up as expected. However, it soon changed status to “The calendar … is momentarily not available” and has stayed that way since.

Just now, I’ve been trying to subscribe to several public calendars that are not hosted by Google, e.g. webcal://www.allsvenskan.se/prenumerera-pa-matcherna-i-din-kalender/aik.ics and https://www.calendarlabs.com/ical-calendar/ics/76/US_Holidays.ics. However, both of them fail the “Validating calendar resource…” step.

If my guess is correct that the background synchronization occasionally succeeds, I believe it would be an improvement to let the user add the calendar regardless of the outcome of the calendar resource validation. Perhaps a button “Add anyway” in the failure dialog. That way, the app would periodically retry fetching it for me in the background.

EDIT: Here’s some output from adb logcat '*:W' 'icsx5:V' when pulling to refresh in ICSx5 with a single calendar subscription:
