vdirsyncer is currently tested against the latest versions of Radicale and
ownCloud.

Radicale
========

Radicale doesn't `support time ranges in the calendar-query of CalDAV/CardDAV
<https://github.com/Kozea/Radicale/issues/146>`_, so setting ``start_date`` and
``end_date`` in vdirsyncer's configuration will have no or unpredicted
consequences.

ownCloud
========

ownCloud uses SabreDAV, which had problems detecting collisions and
race-conditions. The problems were reported and are fixed in SabreDAV's repo.
See `Bug #16 <https://github.com/untitaker/vdirsyncer/issues/16>`_ for more
information.

However, given that this is a problem with every setup involving ownCloud, and
that ownCloud is widely used, it apparently isn't big enough of a problem yet.

Server Support
==============

vdirsyncer is currently regularly and automatically tested against the latest
versions of Radicale and ownCloud. In principle, vdirsyncer is supposed to run
correctly with any remotely popular CalDAV or CardDAV server. 

vdirsyncer's synchronization works best if the items have ``UID`` properties.
Items which don't have this property still should be synchronized fine as of
version 1.6, but for performance reasons, such items should rather be the
exception than the rule. For a possible way to automatically fix such items,
take a look at `vfix <https://github.com/geier/vfix>`_.

Radicale
========

vdirsyncer is tested against the git version and the latest PyPI release of
Radicale.

Radicale doesn't `support time ranges in the calendar-query of CalDAV
<https://github.com/Kozea/Radicale/issues/146>`_, so setting ``start_date`` and
``end_date`` for :py:class:`vdirsyncer.storage.CaldavStorage` will have no or
unpredicted consequences.

ownCloud
========

vdirsyncer is tested against the latest version of ownCloud.

ownCloud uses SabreDAV, which had problems detecting collisions and
race-conditions. The problems were reported and are fixed in SabreDAV's repo.
See `Bug #16 <https://github.com/untitaker/vdirsyncer/issues/16>`_ for more
information.

However, given that this is a problem with every setup involving ownCloud, and
that ownCloud is widely used, it apparently isn't big enough of a problem yet.
