Synchronous API #2

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The APIs are designed to work asynchroneously using delegates.

This can be an issue in some cases. (for GUI-less daemons especially)

There needs to be an API for this. (which works better than waitForTicket: 
which is polling events 
every 1/1000s)

Any tool can use NSRunLoop's -currentRunLoop and -runUntilDate to make the async
callbacks work. No user interface is necessary.

All of the GDataObject data classes can be used independently of the 
GDataService
classes as well.

waitForTicket: doesn't poll for events; it polls for completion of the ticket. 
Events happen asynchronously.

So, please don't deprecate waitForTicket: in future releases, as it is useful.

I however think that it would be better if the GData API could provide 
synchronous methods (using NSURLConnection's convenience class method, 
sendSynchronousRequest:returningResponse:error:, to load a 
URL request synchronously, for example)

This would also make GData/ObjC more inline with the API provided by other 
languages (I haven't checked all, 
but Python and Java are in this case it seems).
I think it's much easier (and cleaner) to type something like    
CalendarFeed resultFeed = service.getFeed(feedUrl, CalendarFeed.class);
or
feed = self.cal_client.GetAllCalendarsFeed()
than what is currently required by GData/ObjC what async download isn't 
needed/wanted.

I wrote a synchronous wrapper using NSRunLoop.  Some convenience methods aren't 
necessary, but they would be nice.

Hi Lem, Could you provide your code for the sync wrapper?

The library does include waitForTicket: and waitForCompletionWithTimeout: 
methods for use by unit tests and UI-less tools, so there's no need for a 
wrapper.

Synchronous http fetches are sufficient reason for apps to be rejected from 
Apple's app stores.
