Radicale 2.1.10 - VCard4 problem

    When I edit an contact on Android it is saved as a VCard3 even if it was retrieved as VCard4.
    “davdroid: [syncadapter.ContactsSyncManager] Server advertises VCard/4 support: false”

    EDIT: Using other clients (like Thunderbird+Cardbook Addon) I can create VCard4 contacts on the Radicale server.

    Resulting in the following behavior: Using TB Cardbook to generate Contact results in a VCard4, then editing it with Davdroid results in a new VCard3.

    Is this a bug of DAVdroid or Radicale? Can I circumvent it somehow?

    I already posted that in the Radicale Bugtracker some time ago: https://github.com/Kozea/Radicale/issues/832

    Hello,

    Is there any indication that this could be a DAVdroid problem? If you enable verbose logs, you can see the exact request DAVdroid sends for capability detection and how Radicale replies.

    The source code for VCard 4 detection can be found here: https://gitlab.com/bitfireAT/davdroid/blob/2c5cdf813aa5c6e7a6e9cdb01b6213eae2903cb0/app/src/main/java/at/bitfire/davdroid/syncadapter/ContactsSyncManager.kt#L133

    Not sure though how “hasVCard4” works or what it checks…
    I also could not find a reference logcat (to check against Radicales response)

    But here is the relevant verbose logcat output:

    @n00b42 said in Radicale 2.1.10 - VCard4 problem:

    It checks CARDDAV:supported-address-data for text/vcard with version=4.0. See https://tools.ietf.org/html/rfc6352#section-6.2.2, including the example.

    The pretty-printed server reply:

    <?xml version="1.0" encoding="utf-8"?>
<multistatus xmlns="DAV:" xmlns:CR="urn:ietf:params:xml:ns:carddav" xmlns:CS="http://calendarserver.org/ns/">
  <response>
    <href>/mail%40example.net/COLLECTION-ID/</href>
    …
    <propstat>
      <prop>
        <CR:supported-address-data/>
      </prop>
      <status>HTTP/1.1 404 Not Found</status>
    </propstat>
  </response>
</multistatus>

    RFC 6352:

    In the absence of this property, the server MUST only accept data with the media type “text/vcard” and vCard version 3.0, and clients can assume that is all the server will accept.

    Thank you, I added the relevant information to my Radicale bug report.
