* gtk/gtksignal.h:
* gtk/gtksignal.c:
ok, there have been several severe bugs in the signal handler
referencing and ->next connection stuff. these bugs caused
invokations of handlers that are disconnected and - worse -
destroyed already. invokation of *destroyd* handlers mean:
anything can be executed , because the handler structure can just
as well be realocated.
at the cost of an extra ->prev field per handler we should have a
reasonable stable system now, because of the various places that
can cause a handler to be disconnected (*any* handler invokation can
cause *any* or *all* handlers to be disconnected, there is no way
around a doubly linked list, actually handler disconnection has never
worked correctly because of this.
handlers are connected together via a *doubly* linked list now, and it
is *not* valid to remove a handler out of this list untill all its
references have been droped, i.e. handler->ref_count==0.
to prevent emissions of disconnected but still referenced handlers,
disconnected handlers are simply marked as blocked and get an id of 0
which is an invalid signal handler id.
the handler->id has been changed to have 28 significant bits (using
alignment gaps), since 65536 (old range: guint16) signal connections
(as a total) can easily be reached by complex applications.
this whole handler thingy is at least as tedious as writing doubly
linked list implementations ;)
