That would still leave people to use the other stuff in the Transfer namespace
that's in transfer-progress.h. So they'd be using Transfer2 sometimes and
Transfer at other times.

I'd prefer to totally deprecate the Transfer namespace. That would mean we must
create a transfer-progress-2.[h|cc] file.

> mostly the same code being duplicated

You might want to reimplement Transfer stuff in terms of Transfer2 to, to
reduce copy/pasting.

And we can lose the existing Transfer example code. It should just use the
non-deprecated Transfer2 API.

"Transfer2" isn't an ideal name, but I can't think of a better name. 

> I haven't added the implementation of Transfer::remove(StringArrayHandle&...).
> ABI break or not?

Sorry, I don't know what you mean. If you can produce a complete patch, I will,
of course, check it for ABI breaks.

So, possibly we are deleting the C++ instance but not unrefing the C instance.

------- Comment #9 from austinf gmail com  2006-11-27 23:09 UTC -------
This has been my workaround that seems to fix it...

in the expose function,

cairo_t* crc = do_cairo_create();
Cairo::Context* cr = new Cairo::Context(crc, true);
draw(cr);
delete cr;

Created an attachment (id=77301)
 --> (http://bugzilla.gnome.org/attachment.cgi?id=77301&action=view)
cairo_refs.patch

I found that and 2 other places where we do excess references, in different
ways. This patch should fix that, though I'd like you to test it a bit before I
commit it. I feel like I've done this before, though maybe it was something
else.

------- Comment #11 from jonner  2006-11-28 18:35 UTC -------
I haven't looked at this at all yet.  Are you saying that there are no problems
in  Cairo::RefPtr itself, just in gtkmm functions that use cairo them?
