Hi, Erik
When I try to compile recent usocket trunk code, two issues found:
In condition.lisp, the (define-condition insufficient-implementation)
cannot compiled on LispWorks:
**++++ Error in (SUBFUNCTION
(DEFCLASS USOCKET:INSUFFICIENT-IMPLEMENTATION)
(DEFINE-CONDITION USOCKET:INSUFFICIENT-
IMPLEMENTATION)):
FUNCTION is defined as an ordinary function #<Function
SYSTEM::UNDEFINED-FEXPR-FUNCTION 20259C4A>
I checked CLHS ( http://www.lispworks.com/documentation/HyperSpec/Body/s_fn.htm
), it says FUNCTION is a "Special Operator" which serves as a
function:
(defun adder (x) (function (lambda (y) (+ x y))))
(setq add3 (adder 3)) (funcall add3 5) => 8
So you define it into a slot reader will cause symbol conflict with
Common Lisp itself. LispWorks is quite strict, other CLs just pass it.
I suggest you use FUNCTION-OF instead of FUNCTION, like this:
(define-condition insufficient-implementation (error)
((feature :initarg :feature :reader feature)
(function :initarg :function :reader function-of))
(:documentation "The ancestor of all errors usocket may generate
because of insufficient support from the underlying implementation
with respect to the arguments given to `function'.
One call may signal several errors, if the caller allows processing
to continue.
"))
With this change, I can compile and load on LispWorks now. But I don't
know where else you use this reader function. Please review this, and
make some change for LispWorks.
Thanks,
