** :ALLOW-OTHER-KEYS NIL is now accepted in an initarg list.
changes in sbcl-0.8.0 relative to sbcl-0.8alpha.0
- * minor incompatible change: the :NEGATIVE-ZERO-IS-NOT-ZERO feature
+ * SBCL now builds using CLISP (version of late April 2003 from CVS) as
+ cross-compilation host. As a consequence, we can now bootstrap our
+ way up to SBCL starting with a bare gcc toolchain and human-readable
+ source code (first the source to CLISP, then the source to SBCL).
+ * A contributed module containing a partial implementation of the
+ simple-streams interface has been included. (thanks to Rudi
+ Schlatte)
+ * A contributed module implementing the RFC1321 Message Digest
+ Algorithm, known as MD5, has been included.
+ * minor incompatible change: The :NEGATIVE-ZERO-IS-NOT-ZERO feature
no longer has any effect, as the code controlled by this feature
has been deleted. (As far as we know, no-one has ever built using
this feature, and its semantics were confused in any case).
- * SB-MOP:DIRECT-SLOT-DEFINITION-CLASS and
- SB-MOP:EFFECTIVE-SLOT-DEFINITION-CLASS now have the
- specified-by-AMOP lambda list of (CLASS &REST INITARGS).
- * compiler checks for duplicated variables in macro lambda lists.
+ * minor incompatible change: As a consequence of making SLOT-EXISTS-P
+ work on conditions (as required by the ANSI specification),
+ SLOT-VALUE, (SETF SLOT-VALUE) and SLOT-BOUNDP likewise have the
+ expected behaviour on conditions. Users should note, however,
+ that such behaviour is not required by the ANSI specification,
+ and so use of this behaviour may render their code unportable.
* fixed some bugs revealed by Paul Dietz' test suite:
** the GENERIC-FUNCTION type is no longer disjoint from FUNCTION
types.
** &ENVIRONMENT parameter in macro lambda list is bound first.
+ ** SXHASH on condition objects no longer returns NIL.
+ ** :ALLOCATION :CLASS slots are better treated; their values are
+ updated on class redefinition, and initforms inherited from
+ superclasses are applied.
+ ** REMOVE-METHOD returns its generic function argument even when
+ no method was removed.
+ ** SHARED-INITIALIZE now initializes the values of the requested
+ slots, including those with :ALLOCATION :CLASS.
+ ** ALLOCATE-INSTANCE now works on structure classes defined via
+ DEFSTRUCT (and not just by those from DEFCLASS :METACLASS
+ STRUCTURE-CLASS).
+ ** SLOT-EXISTS-P now works on conditions, as well as structures
+ and CLOS instances.
+ ** MAKE-LOAD-FORM now has the required methods on
+ STRUCTURE-OBJECT, CONDITION and STANDARD-OBJECT.
+ ** MAKE-LOAD-FORM-SAVING-SLOTS no longer returns a special
+ keyword, and now implements the SLOT-NAMES argument.
+ ** methods with &OPTIONAL arguments no longer allow too many
+ arguments to be passed in the call without error.
+ ** DEFGENERIC now checks that the :ARGUMENT-PRECEDENCE-ORDER
+ option is consistent with the required arguments of the generic
+ function lambda list.
+ * bug fix: REQUIRE accepts a string designator. (Thanks to
+ Antonio Martinez.)
+ * bug fix: SB-MOP:DIRECT-SLOT-DEFINITION-CLASS and
+ SB-MOP:EFFECTIVE-SLOT-DEFINITION-CLASS now have the
+ specified-by-AMOP lambda list of (CLASS &REST INITARGS).
+ * bug fix: The compiler now checks for duplicated variables in macro
+ lambda lists.
+ * bug fix: SETQ on globals returns the correct value.
+ * fixed bug 47.d: (DEFGENERIC IF (X)) now signals a PROGRAM-ERROR,
+ not a COMPILER-ERROR (followed by some other strange error on
+ choosing the CONTINUE restart).
+ * bug fix: make.sh and friends are now more consistent in the way that
+ they look for GNU "make".
+changes in sbcl-0.8.1 relative to sbcl-0.8.0:
+ * minor incompatible change: some nonsensical specialized lambda
+ lists (used in DEFMETHOD) which were previously ignored now signal
+ errors.
+ * minor incompatible change: the system is now aware of the types of
+ variables in the COMMON-LISP package, and will signal errors for
+ most violations of these type constraints (where previously they
+ were silently accepted).
+ * minor incompatible change: COMPILE-FILE now uses the freedom
+ afforded (ANSI 3.2.2.3) to use derived function types for
+ functions defined in the same file. This also permits the system
+ to warn on static type mismatches and function redefinition.
+ * changes in type checking closed the following bugs:
+ ** type checking of unused values (192b, 194d, 203);
+ ** template selection based on unsafe type assertions (192c, 236);
+ ** type checking in branches (194bc).
+ * VALUES declaration is disabled.
+ * a short form of VALUES type specifier has ANSI meaning.
+ * fixed bug in DEFSTRUCT: once again, naming structure slots with
+ keywords or constants is permissible.
+ * STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE now have methods
+ defined on the relevant FUNDAMENTAL-BINARY-{INPUT,OUTPUT}-STREAM
+ classes. (thanks to Antonio Martinez)
+ * improved ANSIness in DESCRIBE: The DESCRIBE function no longer
+ outputs FRESH-LINE or TERPRI, and no longer converts its stream
+ argument to a pretty-print stream. Instead, it leaves any such
+ operations to DESCRIBE-OBJECT methods.
+ * bug fix: APROPOS now respects the EXTERNAL-ONLY flag. (reported
+ by Teemu Kalvas)
+ * bug fix: NIL is now a valid destructuring argument in DEFMACRO
+ lambda lists. (thanks to David Lichteblau)
+ * bug fix: defining a generic function with a :METHOD-CLASS being a
+ subclass of STANDARD-METHOD no longer causes stack exhaustion.
+ (thanks to Gerd Moellmann)
+ * increased compilation speed of long MULTIPLE-VALUES-BIND.
+ * a contributed module implementing COMPILER-LET and MACROEXPAND-ALL
+ has been included.
+ * DEFCONSTANT now throws a condition of type
+ SB-EXT:DEFCONSTANT-UNEQL if it is being asked to redefine a
+ constant to a non-EQL value; CONTINUE and ABORT restarts
+ respectively change and preserve the value.
+ * fixed bug 63: the code walker, part of the implementation of CLOS,
+ is better at handling symbol macros.
+ * bug fix: there is no longer a type named LENGTH. (reported by
+ Raymond Toy)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** NIL is now allowed as a structure slot name.
+ ** arbitrary numbers, not just reals, are allowed in certain
+ circumstances in LOOP for-as-arithmetic clauses.
+ ** multiple class redefinitions before slot access no longer
+ causes a type error.
+ ** (SETF FIND-CLASS) now accepts NIL as an argument to remove the
+ association between the name and a class.
+ ** generic functions with non-standard method-combination and over
+ six methods all of which return constants no longer return NIL
+ after the first few invocations. (thanks to Gerd Moellmann)
+ ** CALL-NEXT-METHOD with no arguments now passes the original
+ values of the arguments, even in the presence of assignment.
+ ** functions [N]SUBST*, LAST, NRECONC, [N]SUBLIS may return any
+ object.
+ ** DISASSEMBLE works with closures and funcallable instances.
+ ** ADD-METHOD now returns the generic function, not the new
+ method.
+ ** FIND-METHOD signals an error if the lengths of the specializers
+ is incompatible with the generic function, even if the ERRORP
+ argument is true.
+ ** TYPE-OF returns recognizeable subtypes of all built-in-types of
+ which its argument is a member.
planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
- down, maybe in 0.7.x, maybe later, it might impact TRACE. They both
- encapsulate functions, and it's not clear yet how e.g. UNPROFILE
- will interact with TRACE
- and UNTRACE. (This shouldn't matter, though, unless you are
- using profiling. If you never profile anything, TRACE should
- continue to behave as before.)
