Fixed a problem on certain caldav server (LINE Works).

[mtorange]

This server returns empty data result (URL only) from date search.
So we have to re-query the data for every event after fetching urls. calendar_multiget() has been added for it.
And the exception on _calendar_comp_class_by_data() on empty data result has been fixed

Is it possible to create some test code for this?

Is it possible to create some test code for this?

below is my working code.
but I have no idea how can I create test code (we need specific CalDAV server for testing)

def get_events(url, user, password, calendar_name):
	start_dt = datetime.today() - timedelta(days=7 * 3)
	end_dt = datetime.today() + timedelta(days=7 * 12, hours=23, minutes=59, seconds=59)

	client = DAVClient(url, username=user, password=password)
	principal = client.principal()
	calendars = principal.calendars()

	for c in calendars:
		if calendar_name == c.name:
			events = c.date_search(start_dt, end_dt)
			if len(events) > 0 and events[0].data is None: # <-- server returns events with empty data
				events = c.calendar_multiget([ev.url for ev in events])
			return events
	return None

I'll merge this for now, but raise an issue that ...

• The multiget method should be exercised in test code, for servers that supports multiget
• Should add an extra parameter to date_search method to allow it to try to do a multiget if needed
