** GOOPS
|

|

Two major changes have been made:
|
||||
|
||||
1- #:init-value on class-allocated slots: allocating an instance of a
|
||||
class with a #:class or #:each-subclass slot allocation should not
|
||||
re-initialize the class-allocated slot.
|
||||
|
||||
2- accessor methods only apply to subclasses with their slot
|
||||
|
||||
FIXME
|
||||
(a) let users know that it will break Goops user code relying on
|
||||
previsouly inherited getters, setters and accessors ... (b) why this: so
|
||||
that Guile 2.x.x behave like guile-1.8 wrt Goops. But the full picture
|
||||
is rather strange, and will be (re)fixed soon, see this discussion
|
||||
http://thread.gmane.org/gmane.lisp.guile.user/11218/focus=11813 for some
|

details.

** 'string-hash', 'read-string', and 'write' have been optimized

|
||||
** GOOPS bug fix for inherited accessor methods
|
||||
|
||||
In the port of GOOPS to Guile 2.0, we introduced a bug related to
|
||||
accessor methods. The bug resulted in GOOPS assuming that a slot S in
|
||||
an object whose class is C would always be present in instances of all
|
||||
subclasses C, and allocated to the same struct index. This is not the
|
||||
case for multiple inheritance. This behavior has been fixed to be as it
|
||||
was in 1.8.
|
||||
|
||||
One aspect of this change may cause confusion among users. Previously
|
||||
if you defined a class C:
|
||||
|
||||
(use-modules (oop goops))
|
||||
(define-class C ()
|
||||
(a #:getter get-a))
|
||||
|
||||
And now you define a subclass, intending to provide an #:init-value for
|
||||
the slot A:
|
||||
|
||||
(define-class D ()
|
||||
(a #:init-value 42))
|
||||
|
||||
Really what you have done is define in D a new slot with the same name,
|
||||
overriding the existing slot. The problem comes in that before fixing
|
||||
this bug (but not in 1.8), the getter 'get-a' would succeed for
|
||||
instances of D, even though 'get-a' should only work for the slot 'a'
|
||||
that is defined on class C, not any other slot that happens to have the
|
||||
same name and be in a class with C as a superclass.
|
||||
|
||||
It would be possible to "merge" the slot definitions on C and D, but
|
||||
that part of the meta-object protocol (`compute-slots' et al) is not
|
||||
fully implemented.
|
||||
|
||||
Somewhat relatedly, GOOPS also had a fix around #:init-value on
|
||||
class-allocated slots. GOOPS was re-initializing the value of slots
|
||||
with #:class or #:each-subclass allocation every time instances of that
|
||||
class was allocated. This has been fixed.
