Doesn't sync with davical

  • developer

    @khades Yes, please see the posting in the mailing list I have linked above. If you have any suggestions why this problem occurs, please post here (or there if it’s DAViCal-related – I think it is).

  • can you please tell how you did send multiget request with curl? cant make it work with xml you provided in davical-general.

  • developer

    @khades curl --data @request.xml --user name:passwd -H "Content-Type: application/xml" -X REPORT https://server/path/to/collection/
    (put the multiget request from the list into request.xml)

  • fast kinda fix
    if ( empty($properties) ) $properties[‘DAV::allprop’] = 1;
    changed in
    $properties[‘DAV::allprop’] = 1;

    in caldav-REPORT-multiget.php of davical
    now it returns etags, but not data. It wasnt returning even etag.

    (i added some more output logging)

    now there’s other problem, what is actual bugtracker of davical? i know there’s davical development on git, and you posted to sourceforge

    so there’s problems in properties query.

    Does davdroid query for specific properties?

  • [DAV::href] => 1
    is in that properties, so it doesnt add allprop

  • riiiight. it is davdroid problems probably, it should request for DAV::getetag and urn:ietf:params:xml:ns:caldav:calendar-data

    i added kinda cludge

    i added in caldav-REPORT-multiget.php

    if (( count($properties) == 1) && ( $properties[‘DAV::href’] == 1)) {
    $properties[‘DAV::getetag’] = 1;

    if ( empty($properties) ) $properties[‘DAV::allprop’] = 1;

    and it worked.

  • that props i got from thunderbird\sunbird query

  • developer

    So where’s the problem? DAVdroid requests DAV:getetag and CALDAV:calendar-data / CARDDAV:addressbook-data. Can you give me a hint?

  • it doesnt request any of CALDAV:calendar-data / CARDDAV:addressbook-data, i checked that adding logs in caldav-REPORT-multiget.php

    $fd = fopen("/tmp/php-davical", “a”);
    // write string
    fwrite($fd, print_r($properties, true)."\n");
    // close file


    if ( empty($properties) ) $properties[‘DAV::allprop’] = 1;

    and it did shown me that nothing was requesting except href

  • developer

    DAVdroid does request getetag and calendar-data/addressbook-data, but maybe DAViCal doesn’t understand the request and thinks that nothing of it was requested? Or please give me hint what could be wrong in the request.

  • how to log what xml and type of request is made in davdroid? in what class does it generate?

  • developer

    The adb logcat with tag “davdroid” shows generated requests (they’re logged). The multiget request is created here (but of course other classes are involved/referenced).

    In line 290/292 you can see how the addressData/calendarData prop is set for the request.

  • developer

    @khades Can you please try to put the <href>s after the <prop> in the request (with curl again) and check if it works for you?

  • didnt understood what you want

  • developer

    Can you try doing the request with curl again, but not


    but with


    and see if DAViCal then parses the request correctly?

  • yes, it works that way

  • Great, Thanks a lot, I will confirm it’s working in next release
