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). + * 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. + * 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. 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.
