New Attachment: Ical.patch Download		 Reply to this comment
I believe I have have found the problem:

in file kronolith/lib/Driver/Ical.php, line 431/2 (as of kronolith 4.2.22)
_processComponents is called with one argument missing:

     431                 $this->_processComponents($results, $ical, 
null, null, false,
     432                                           false, false, $eventId);

resulting in an event with an empty $id, which in turn becomes 'ical' 
. $i in line 342.

Adding one "false, " (is that the right thing to add?) ad the 
beginning of line 433 seems to fix the problem for me (see patch 
attached).

If I read the logs correctly, when modifying/deleting an existing 
event, it is read once again before the actual modification, and this 
reading fails.

This log entry:

2015-06-21T09:49:13+02:00 DEBUG: HORDE5 [kronolith] SQL  (0,0003s)
         SELECT x(event_coordinates) as lat, y(event_coordinates) as lon,
           event_zoom as zoom FROM kronolith_events_mysqlgeo WHERE event_id =
           'ical0' [pid 26317 on line 321 of
"/usr/share/php/Horde/Db/Adapter/Mysqli.php"]

(copied from below)

must be a result of line 335 of 
/usr/share/php/www/horde/kronolith/lib/Driver/Ical.php, where the 
event_id of the item to be read is composed - this works when opening 
an existing event, but when modifying/deleting it, this line:

335                 $event->id = $id ? $id : 'ical' . $i;

ends in the event_id being "ical0" or "ical1" (some missing input value?).

This is irrelevant because it's a strict warning.

one more line might be relevant:

2015-06-21T09:49:13+02:00 DEBUG: HORDE5 [kronolith] PHP ERROR: Only 
variables should be passed by reference [pid 26317 on line 426 of

I think I'd better attach the full log, in case there is more to find 
that I didn't spot.

I cannot see much in the horde debug logs either (does it log the 
calls to davical at all?)

This is where the davical event is created:

Priority ⇒ 2. Medium
Type ⇒ Bug
Summary ⇒ cannot modify/delete external caldav events
Queue ⇒ Kronolith

Patch ⇒ No
State ⇒ Unconfirmed		 Reply to this comment
I have an external caldav calendar in Kronolith (Davical 1.1.3.1). I 
can view and add events, but I cannot modify or delete events. Access 
from Lightning works fine, using Lightning I can also modify/delete 
events created by Kronolith.

When I try to modify/delete an event with Kronolith I get a "Resource 
not found" error and the following Apache log:

127.0.0.1 - martin [20/Jun/2015:10:51:21 +0200] "GET 
/davical/caldav.php/martin/calendar/ical0 HTTP/1.1" 404 465 "-" 
"Horde_Http 2.1.5"

sometimes I see ical1 instead of ical0.

Creating this very event looked like this:

127.0.0.1 - martin [20/Jun/2015:10:51:11 +0200] "PUT 
/davical/caldav.php/martin/
calendar/5585297f-1ed8-483c-9d06-5c4e00000000.ics HTTP/1.1" 201 485 
"-" "Horde_H
ttp 2.1.5"

This is not a recent regression, it has been like this for quite some 
time (I have logs back to October 2014, but it might be older).

My guess is that Kronolith somehow doesn't get the event ID right (but 
my understanding of Horde code ends here...).

I have tried deleting/re-adding the external calendar in Kronolith and 
creating a new principal in Davical but the problem remained the same. 
Davical logs show nothing interesting, other than the fact that Horde 
requested "ical0" which does not exist.

I have seen that Apache mod_rewrite can create problems, so I have 
tried disabling mod_rewrite, but it didn't change anything. Anyway, I 
have no rewrite rules enabled.

Thanks in advance for any hint! If I can help with any log- or 
conf-files, please let me know.
