Re: Module proposal: gio and gvfs for gnome 2.22?

The file selector and file manager seem like the most pathological
users of an IO API.  Do we want to expose another largish API because
of their requirements?  That was what led to gnome-vfs in the first

ISVs typically don't use gnome-vfs because it doesn't work x-desktop,
and I don't see that changing by pushing it lower in the stack.  Maybe
removing the added dependency burden will make it more accessible, I

Most apps that I use every day (firefox, thunderbird, OOo, emacs) are
unlikely to switch to gio for anything other than opening files via
the open dialog.  So it's not like pushing gnome-vfs lower is going to
suddenly make URLs/paths work the same across the desktop.

Are there any stats on gnome-vfs usage?  Who uses what?  Several of
the things you mention (content types, icons, app info) are wrappers
for xdg specs and tools. I could see that growing to include volume
and file monitoring (one can hope).

Would growing xdg APIs be more sustainable than exposing libgio as
part of glib?  Or do you think the uphill battle with xdg is not worth

(I'll stop being a cranky old fart now...)
