[Kolab-devel] [issue4498] Single events from a shared calendar folder doesn't available in DIMAP Cache (rt#6198)

[Emanuel Schuetze]

New submission from Emanuel Schuetze <emanuel at intevation.de>:

Critical e35 user report (reported by several users):

Precondition:
* user X with calendar folder C
* user A has write access to C
* user B has write access to C
* A, B and X use DIMAP with Kolab Server

Scenario:
1. A creates an event E in C
2. after undefined time (sometimes after next syncm, sometimes after some
days/weeks): 
   => A looks at C: E is NOT visible!
   -> B looks at C: E is visible.
3. checks:
   -> E is available at Server
   -> E is NOT available in A's DIMAP cache
   -> E is available in B's DIMAP cache
4. refresh DIMAP cache of A and sync
   => A looks at C: E is now visible!

C contains about 1100 events.
Scenario not reproducable!

Analysis:
Looks like a special DIMAP cache problem.
Compare attached kmailrc files (extracts) of A before (see
1_kmailrc-without-event.txt) vs. after (see 2_kmailrc-with-event.txt)
step (4). Noticeable:
a) "Compactable=false" vs "Compactable=true"
b) "Top=-1" vs ""
c) "Current=0" vs ""
d) "OrderOfArrival=false" vs ""
etc.

Can you find some strange options in the kmailrc? 
Can you explain why the above-named options changed?
What does the additional line "Kalender-changes=1" in 1_kmailrc-without-event.txt?

Open pivotal questions:
-> Which action triggers this problem?
-> When (after event creation) the problem is triggered?

Tested with e35 v20100618 (and newer).
Very critical for our customer!
