Package: davical
Version: 0.9.9.5-1
Severity: normal
Dear Maintainer,
I noticed recently that my davical calendars do not show any events in the
future
(other then recurring events), while Evolution does. I can add new events on
iPhone
for any date, but those in the future will disappear from the calendar as viewd
by
iPhone.
After some investigation, a downgrade to 0.9.9.4-1 resolved the problem.
I stumbled upon two curious observations that *might* be related:
1a. tcpflow capture of data shows that indeed no VEVENT for a future date gets
delivered to iPhone
1b. iPhone seems to request data starting 2 month in the past.
<x0:calendar-query xmlns:x1="DAV:" xmlns:x0="urn:ietf:params:xml:ns:caldav">
<x1:prop><x1:getetag/><x1:resourcetype/></x1:prop><x0:filter>
<x0:comp-filter name="VCALENDAR"><x0:comp-filter name="VEVENT">
<x0:time-range start="20110828T220000Z"/>
</x0:comp-filter></x0:comp-filter>
</x0:filter></x0:calendar-query>
Might lack of a rang-end be interpreted as "now" insted of "+infinity"? (in
0.9.9.5-1)
2a. I noticed garbled request after initial contact from iPhone in Apache log:
xxx.lan:443 xxx - xxx [29/Sep/2011:22:03:42 +0200] "PROPFIND
/caldav.php/xxx/home/ HTTP/1.1" 207 2779 "-" "DAVKit/5.0 (770); iCalendar/5.0
(79); iPhone/4.3.5 8L1"
xxx.lan:443 xxx - xxx [29/Sep/2011:22:03:42 +0200] "PROPFIND
/caldav.php/xxx/%0A%2520%2520%2520%2520%2520/caldav.php/xxx/todo/ HTTP/1.1" 404
763 "-" "DAVKit/5.0 (770); iCalendar/5.0 (79); iPhone/4.3.5 8L1"
2b. tcpflow showed that in 0.9.9.4-1, I get 1 "C:calendar-home-set", while I
get 2 in 0.9.9.5-1
<response>
<href>/caldav.php/xxx/</href>
<propstat>
<prop>
<principal-collection-set>
<href>/caldav.php/</href>
</principal-collection-set>
<C:calendar-home-set>
<href>/caldav.php/xxx/</href>
</C:calendar-home-set>
vs
...
<C:calendar-home-set>
<href>/caldav.php/xxx/</href>
<href>/caldav.php/xxx/todo/</href>
</C:calendar-home-set>
2c. This may be related to code that uses this DB query (in 0.9.9.5-1)
SELECT DISTINCT parent_container FROM collection WHERE is_calendar and dav_name
~ '^/xxx';
2d. This 404 failure causes iPhone not show no list at all of existing
calendars on davical.
