Calendar gets synchronized, but Contacts don't (OC 7)

    Hello!

    After updating to the latest version of DAVdroid, I’ve been having problems with my address book. While calendar synchronization works flawless, contacts just aren’t synchronized. Reinstalling DAVdroid did not resolve the issue. The server is running the latest version of ownCloud 7.

    I’d appreciate any suggestions. 🙂

    Let me post the log I got:

    I’ve got the same error.

    Same DAVDroid Version, from Playstore.

    Not shure about the OC version, but definitely 7 or even older.

    Your OwnCloud is defect. Please update to a recent version.

    Oups sorry I didn’t see it was about OwnCloud…
    I don’t use it but I have the same problem since the last update, so I will open my own topid…

    It can’t be that defect, as it worked very well for more a year. Or could you give us a hint about what’s wrong with our OC version?

    I, too, would rather downgrade to an earlier DAVdroid version (which worked great) than upgrade ownCloud which I haven’t done yet for a couple of reasons…

    Would you happen to have any other suggestions?

    As you can see from the debug logs, your server responds with 500 Internal Server Error to a REPORT addressbook-query request.

    You’re of course free to use any DAVdroid version you want 🙂

    Would you happen to have any other suggestions?

    DAVdroid has an ugly fallback-hack that falls back to PROPFIND when a server responds with some defined HTTP error codes (like 400 Bad Request and 403 Forbidden) to REPORT addressbook-query. This ugly fallback-hack will now be activated for the following status codes (on REPORT addressbook-query😞

    • 400 Bad Request – this is what a server sends when it thinks the REPORT is invalid
    • 403 Forbidden – some servers refuse the empty <filter/> and say that it’s not a supported filter type, so the correct response code for that is 403
    • 500 Internal Server Error – some servers (like yours) just don’t know what to do and return an “all-catch” error
    • 501 Not Implemented – that would be the right error code for a server that knows it MUST support REPORT addressbook-query, but it’s not implemented nevertheless.

    So, with this ugly fallback-hack in the next DAVdroid release, you will (hopefully) be able to sync again with your OwnCloud 7 installations – but that doesn’t change anything about the fact that they’re defect.

    Should have been worked around by DAVdroid 0.9.0.4, can you please confirm?

    @studerap It seems that your server tells DAVdroid there are 0 contacts. Please take verbose logs and post them as a snippet or something similar.
