Multiget, multiget everywhere!

I spent last days going through sequence of handler functions and understanding at what points I should query for schedule-tag from the server.

There are 3 handlers in the calDavRequestHandlers.js

etags handler
webdavSync Handler
multigetSync Handler

Each handler parses the retrieved xml REST message with nsiSaxParser. At the end of parsing, [when reached to endDocument() function], it calls doMultiget() with a set of items that are identified need fetching.

If an item detected which was deleted, newly created or updated from etags it will be added to the list, itemsNeedFetching{}.

Items will be fetched in doMultiget().

So I decided adding the query, <C: schedule-tag> within multiget would do the thing. (WebDav sync doesn’t return a schdule-tag anyway)

Then the schedule-tag will be added to the list, mItemInfoCache with respected UID with  property name “scheduleTag” (I removed the hyphen in middle of the Local name). This may cause to add a null value for the mItemInfoCache[].scheduleTag and I will manage it in If-Schedule-tag-Match property implementation.

I think this will pretty much cover the retrieval of schedule-tag property.

I found another regression in the code, which spoof the OPTIONS request when dealing with Google calendar.  I found that currently with CalDav v2, Google supports OPTIONS method. So there won’t be any need to spoof the method.  I’ll put this in my todo list as well.

My next step is implementing if-schedule-tag-match property.
