[Gaim-devel] Use of handles and reference counting for the request API

[Evan S. <ev...@dr...>]

So I'm facing a bit of confusion regarding the request API.  Assume  
I'm using some sort of reference counting system, and the objects I  
want to return as handles are destroyed when their reference count is  
0 (of course).  There are two non-crashing possibilities as I see it:

1. Request window is shown; I increase the reference count to return  
the handle
2. User interacts with the window, and it closes.
3. There is no three.  The reference count is now permanently +1

or
1. Request window is shown; I increase the reference count to return  
the handle
2. libgaim requests a close of the window via  
gaim_request_close_with_handle()
3. I close the window and decrease the reference count.

If I don't increase the reference count before returning, the  
following crashy situation occurs:
1. Request window is shown.
2. libgaim requests a close of the window via  
gaim_request_close_with_handle()
3. I attempt to close the window. If my handle-object was  
dereferenced elsewhere, it was already destroyed, and I crash when  
accessing invalid memory.

Any thoughts or suggestions?

Thanks,
Evan
