For async to work properly, you must run the GLib MainLoop. MainLoop is where your async closure for test_function.begin() is called. It's where all callbacks are scheduled, actually.
The only reason this works is that in the case of DO_YIELD you stash the test_function.callback and then call it back. That's why you're seeing "End callback called 1". A better way to do this is to (a) get rid of ext_callback and (b) call "new GLib.MainLoop().run()" right before the "return 0" in main(). Without actually modifying the code (i.e. I'm doing this off the top of my head), that should work. -- Jim On Mon, Oct 22, 2012 at 2:47 PM, rastersoft <ras...@rastersoft.com> wrote: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all: I was working with async methods, and found something odd: if I call an async method, but, for whatever reason, I never call YIELD inside, the end callback function is never called. I attach an example: by compiling it with valac -D DO_YIELD -o test_async test_async.vala --pkg=gio-2.0 will do a YIELD inside the async function. But when compiled with valac -o test_async test_async.vala --pkg=gio-2.0 will not. In the former case you can see how "End callback called 1" is printed, because the callback for the end is called; but in the later, it's not printed. Is that a bug? If not, why does it work that way?
