Hello Rotty
I just noticed that you have added the following code in file
compat.scm in version 1.9.9.
;; Hack to make WCTs nullable (null-ok) by default, as in G-Wrap 1.3.4
(define-method (make-typespec (type <gw-wct>) (options <list>))
(next-method type (if (memq 'non-null options)
(cons 'caller-owned (delq 'non-null options))
(append '(null-ok caller-owned) options))))
It seems the module (g-wrap compat) gets loaded irrespective of
whether you want to have version 1.3.4 compatibility or not. As a
result it becomes impossinble to define non-nullable wct's.
My application for example crashes when a null(#f) is given as an
argument to some wrapped functions. For now I have solved the problem
by hacking the g-wrap installed at my site and commenting out the
above quoted code. Is there a cleaner way for me to handle such a
situation.
To make it clear I will summaries -- My application crashes when a
NULL(#f) argument is given to some functions. I want the applcation to
give an "wrong type arg" error message instead. With the code added in
the latest version compat.scm, it does not seem possible as "null-ok"
is getting added to all wct arguments by default.
Regards
Puneet
