Bug#438979: korganizer's poor syncronization behaviour causes data lost
Package: korganizer
Version: 4:3.5.7-2
Severity: grave
--- Please enter the report below this line. ---
Using a remote calendar on different machines is extremely dangerous. It
looks like korganizer just overwrites the local calendar when
(re)loading the remote calendar and just overwrites the remote calendar
when saving the local one.
This leads to dangerous situations as happened for me a few minutes ago.
Korganizer failed for some reason to load the changes I've made on a
remote calendar yesterday on startup of korganizer. I made some changes,
not knowing that I was working with an outdated copy of my calendar.
When korganizer finally saved the local changes to the remote calender,
all my changes I've made yesterday on the other machine where gone.
Korganizer should really make sure not to overwrite newer remote or
local calendars when syncronizing. I think it could use the
LAST-MODIFIED fields in the .ics file to check if the local/remote
event/todo-item is newer.
I've decided to use "grave" because it leads to data loss. "Important"
could be appropriate too since "it's not useless for everyone", but I
think data loss weights more in this case.
Cheers,
Bastian
