Fixes #12770. > > Consider this scenario with a new, empty calendar: > > 1. User inserts the first event. The event is tagged with "foobar". > This tag is inserted into the tagging backend. > 2. User creates another event with a foreign Kolab client. > This event is tagged "Foobar" (noticed the capital 'F') > 3. kronolith syncs in the foreign event. The Kolab sync tells > the tag backend to store the tag(s) for the new event object, > it does a case insensitive search for an existing tag label. > -> it picks the existing row id of "foobar". > > The next time Event::synchronizeTags() runs, it notices > the tags given by the Kolab driver for the second event > differ from the tag backend ("Foobar" != "foobar") > -> A sync is triggered. > > I have a productive calendar with about 2.000 events. > The sync "loop" produces 3.6000+ INSERT / UPDATE statements > on every click. > > Fix it by making the tag label comparison case insensitive. > > Signed-off-by: Michael J Rubinsky <mrubinsk@horde.org> > > kronolith/lib/Event.php \| 6 ++++-- > 1 files changed, 4 insertions(+), 2 deletions(-) > > http://git.horde.org/horde-git/-/commit/24181adf76bef93aaefba40ebf66d25ec1c7a05d
