Calendars become read-only soon after their creation on BusyCal (BusyCal.app, 2022.1.4)

[pofloc221]

After setting a quick server with xandikos --defaults -d ., I have added the CalDAV server to BusyCal. It loaded the default calendar calendar properly, I managed to create a new calendar, add an event and attach a file to it. A few seconds later however, all calendars become read-only, and I couldn't make any change, from modifying an existing event, to making new ones.

Xandikos doesn't do anything to day in terms of permissions management.

What sort of responses do you see on the xandikos side? Can you attach the output of running xandikos with --dump-dav-xml?

❯ xandikos -d . --dump-dav-xml

[jelmer]

Interesting; I don't see anything here to suggest that xandikos is refusing write access.

Is there anything on the client side that suggests the collection is read-only? Some clients (e.g. evolution) have a client-side setting to allow you to mark a collection as read-only.

[walkertraylor]

I have the same problem. Perhaps BusyCal goes read-only in response to detecting one of the unsupported properties?

[jelmer]

The reports of unsupported properties are for properties that BusyCal asks for but that Xandikos doesn't support. It's pretty common, and Xandikos just reports that those properties are not present.

It may be that BusyCal relies on a particular property to be present (and storeable) to understand whether the calendar is read-only. None of the names of unsupported properties seem related to that though.
