some of which are apparent above.
changes in sbcl-0.7.1 relative to sbcl-0.7.0:
-* SB-ALIEN:LOAD-FOREIGN and SB-ALIEN:LOAD-1-FOREIGN are set
- up properly again. (There was a packaging bug in 0.7.0 which
- left their definitions in SB-SYS::LOAD-FOREIGN and
- SB-SYS::LOAD-1-FOREIGN.)
-* DEFGENERIC is now choosier about the methods it redefines, so that
- reLOADing a previously-LOADed file containing DEFGENERICs does
- the right thing now. Thus, the Lispy edit/reLOAD-a-little/test
- cycle now works as it should. (thanks to Alexey Dejneka)
-* Bug 106 (types (COMPLEX FOO) where FOO is an obscure type) was
- fixed by Christophe Rhodes. (He actually submitted this patch
- months ago, and I delayed until after 0.7.0.)
-* Bug 111 (internal compiler confusion about runtime checks on
- FUNCTION types) was fixed by Alexey Dejneka.
-
-planned incompatible changes in 0.7.x:
-* 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.)
-* Inlining can now be controlled the ANSI way, without
- MAYBE-INLINE, since the idiom
+* mostly bug fixes:
+ ** SB-ALIEN:LOAD-FOREIGN and SB-ALIEN:LOAD-1-FOREIGN are set
+ up properly again. (There was a packaging bug in 0.7.0 which
+ left their definitions in SB-SYS::LOAD-FOREIGN and
+ SB-SYS::LOAD-1-FOREIGN. LOAD-FOREIGN and LOAD-1-FOREIGN are
+ vital for most things which interface to C-level interfaces,
+ like extensions working with sockets or databases or
+ Perl-compatible regexes or whatever, and the need to fix
+ this bug is the main reason that 0.7.1 was released so
+ soon after 0.7.0.)
+ ** DEFGENERIC is now choosier about the methods it redefines, so that
+ reLOADing a previously-LOADed file containing DEFGENERICs does
+ the right thing now. Thus, the Lispy edit/reLOAD-a-little/test
+ cycle now works as it should. (thanks to Alexey Dejneka)
+ ** Bug 106 (types (COMPLEX FOO) where FOO is an obscure type) was
+ fixed by Christophe Rhodes. (He actually submitted this patch
+ months ago, and I delayed until after 0.7.0.)
+ ** Bug 111 (internal compiler confusion about runtime checks on
+ FUNCTION types) was fixed by Alexey Dejneka.
+* Some internal cleanups (getting rid of variables which aren't
+ needed now that the byte interpreter is gone) caused the fasl
+ file format number to change again.
+
+changes in sbcl-0.7.2 relative to sbcl-0.7.1:
+ * incompatible change: The compiler is now less aggressive about
+ tail call optimization, doing it only when (> SPACE DEBUG) or
+ (> SPEED DEBUG). (This is an incompatible change because there are
+ programs which relied on the old CMU-CL-style behavior to optimize
+ away their unbounded recursion which will now die of stack overflow.)
+ * minor incompatible change: The default BYTES-CONSED-BETWEEN-GCS
+ for non-GENCGC systems has been increased to 20M (since that
+ seems much closer to the likely performance optimum for modern
+ systems than the old 4M value was)
+ * minor incompatible change: new larger values for *DEBUG-PRINT-LENGTH*
+ and *DEBUG-PRINT-LEVEL*
+ * SBCL runs on SPARC systems now. (thanks to Christophe Rhodes' port
+ of CMU CL's support for SPARC, and various endianness and other
+ SBCL portability fixes due to Christophe Rhodes and Dan Barlow)
+ * new syntactic sugar for the Unix command line: --load foo.bar is now
+ an alternate notation for --eval '(load "foo.bar")'.
+ * bug fixes:
+ ** The system now detects stack overflow and handles it gracefully,
+ at least for (OR (> SAFETY (MAX SPEED SPACE)) (= SAFETY 3))
+ optimization settings. (This is a good thing in general, and
+ its introduction in this version should be particularly timely
+ for anyone whose code fails because of suppression of tail
+ recursion!)
+ ** The system now hunts for the C variable "environ" in a more
+ devious way, to avoid segfaults when the C library version differs
+ between compile time and run time. (thanks to Christophe Rhodes)
+ ** INTEGER-valued CATCH tags now work. (thanks to Alexey Dejneka,
+ and also to Christophe Rhodes for porting the fix to non-X86 CPUs)
+ ** The compiler no longer issues bogus style warnings for undefined
+ classes in the same source file as the DEFCLASSes which defined
+ them. (thanks to Stig E Sandoe for reporting and Martin Atzmueller
+ for fixing this)
+ ** fixes in CONDITION class precedence list for undefined function
+ errors (thanks to Alexei Dejneka)
+ ** *DEFAULT-PATHNAME-DEFAULTS* is used more consistently and
+ correctly. (thanks to Dan Barlow)
+ ** portability fixes aiming at bootstrapping under CLISP (thanks
+ to Dave McDonald and Christophe Rhodes)
+ ** FORMAT fixes (thanks to Robert Strandh and Dan Barlow)
+ ** fixes in type translation and and type inference (thanks to
+ Christophe Rhodes)
+ ** fixes to optimizer internal errors (thanks to Alexei Dejneka)
+ ** various fixes in the new ports (thanks to Dan Barlow)
+ * several changes related to debugging:
+ ** suppression of tail recursion, as noted above
+ ** stack overflow detection, as noted above
+ ** The default implementation of TRACE has changed. :ENCAPSULATE T
+ is now the default. (For some time encapsulation has been more
+ reliable than the breakpoint-based :ENCAPSULATE NIL
+ implementation, at least on X86 systems; and I just noticed that
+ encapsulation also seems closer to the spirit of the ANSI
+ specification.)
+
+changes in sbcl-0.7.3 relative to sbcl-0.7.2:
+ * ANSI's DEFINE-SYMBOL-MACRO is now supported. (thanks to Nathan
+ Froyd porting CMU CL code originally by Douglas Thomas Crosher)
+ * SBCL now runs on the PPC archtiecture under Linux. It actually did
+ this as of 0.7.1.45, but was left out of the previous news section
+ (thanks to Dan Barlow)
+ * SBCL now runs on the Solaris operating system on SPARC architectures
+ (thanks to Christophe Rhodes's port of the CMUCL runtime)
+ * cleanups to the runtime on SPARC, both Linux and Solaris, and for
+ gcc>=3 (thanks to Nathan Froyd and Ingvar Mattsson)
+ * SPARC backend cleanups, allowing builds of cores optimized for V8
+ and V9 SPARCS, and also emission of code targeted to a particular
+ backend chosen at runtime (thanks to Christophe Rhodes and Raymond
+ Toy)
+ * SBCL is closer to bootstrapping under CLISP, thanks to various
+ fixes by Christophe Rhodes.
+ * The fasl file format has changed again, to allow the compiler's
+ INFO database to support symbol macros.
+ * The user manual (in doc/) is formatted into HTML more nicely.
+ (thanks to coreythomas)
+ * The system is smarter about SUBTYPEP relationships, especially
+ those involving NOT types (including types such as ATOM which are
+ represented internally using NOT types). Thus SUBTYPEP is less
+ likely to return (VALUES NIL NIL) in general, and in particular
+ bugs 58 and (the remaining bits of) bug 50 are fixed. (thanks to
+ Christophe Rhodes)
+ * The fasl file format has changed again, because the internal
+ representation of types now includes a new slot to support the new
+ SUBTYPEP-of-NOT-types logic.
+ * (not a change in the main branch of SBCL, but a related prototype
+ which can hopefully be merged into the main branch of SBCL in the
+ future:) Brian Spilsbury has produced a Unicode-enabled variant of
+ sbcl-0.7.0, available as a patch against sbcl-0.7.0 at
+ <http://designix.com.au/brian/SBCL/sbcl-0.7.0-unicode.p0.gz>.
+ * Bug 151 fixed: GET-DISPATCH-MACRO-CHAR now returns NIL for undefined
+ dispatch macro character combinations. (thanks to Alexey Dejneka)
+ * Bugfix in PARSE-NAMESTRING: we now correctly parse unix namestrings
+ that superficially look like logical namestrings correctly.
+ * USER-HOMEDIR-PATHNAME now returns a (physical) pathname that SBCL
+ can deal with.
+ * Bugfix in DEFSTRUCT: BOA constructor lambda lists now accept (name
+ default supplied-p) for &optional and &key arguments. (thanks to
+ Martin Atzmueller)
+
+changes in sbcl-0.7.4 relative to sbcl-0.7.3:
+ * bug 147 fixed: The compiler preserves its block link/count
+ invariants more correctly now so that it doesn't crash. (thanks
+ to Alexey Dejneka)
+ * Dynamic loading of object files in OpenBSD is now supported. (thanks
+ to Pierre Mai)
+ * COMPILE now works correctly on macros. (thanks to Matthias Hoelzl)
+ * GET-MACRO-CHARACTER and SET-MACRO-CHARACTER now represent
+ no-value-for-this-character as NIL (as specified by ANSI).
+ * HOST-NAMESTRING on physical pathnames now returns a string that is
+ valid as a host argument to MERGE-PATHNAMES and to MAKE-PATHNAME.
+ (thanks to Christophe Rhodes)
+ * The Alpha port handles icache flushing more correctly. (thanks to
+ Dan Barlow)
+ * More progress has been made toward bootstrapping under CLISP. (thanks
+ to Christophe Rhodes)
+ * The fasl file format has changed again, because dynamic loading
+ on OpenBSD (which has non-ELF object files) motivated some cleanups
+ in the way that foreign symbols are transformed and passed around.
+ * minor incompatible change: The ASCII RUBOUT character, (CHAR-CODE 127),
+ is no longer treated as whitespace by the reader, but instead as
+ an ordinary character. Thus e.g. (READ-FROM-STRING "A\7fB") returns
+ |A\7fB|, instead of A as it used to.
+
+changes in sbcl-0.7.5 relative to sbcl-0.7.4:
+ * SBCL now builds with OpenMCL (version 0.12) as the
+ cross-compilation host; also, more progress has been made toward
+ bootstrapping under CLISP.
+ * SBCL now runs on the Tru64 (aka OSF/1) operating system on the
+ Alpha architecture.
+ * bug 158 fixed: The compiler can now deal with integer loop
+ increments different from 1; fixing this turned out also to fix
+ bug 164.
+ * bug 169 fixed: no more bogus warnings about using lexical bindings
+ despite the presence of perfectly good SPECIAL declarations (thanks
+ to David Lichteblau)
+ * bug 175 fixed: CHANGE-CLASS is now more ANSI-conforming,
+ accepting initargs. (thanks to Espen Johnsen and Pierre Mai)
+ * bug 179 fixed: DIRECTORY can now deal with filenames with pattern
+ characters in them.
+ * bug 180 fixed: Method combination specifications no longer ignore
+ the :MOST-SPECIFIC-LAST option. (thanks to Pierre Mai)
+ * bug fix: Structure type predicate functions now check their argument
+ count as they should.
+ * bug fix: Classes with :METACLASS STRUCTURE-CLASS now print
+ correctly. (thanks to Pierre Mai)
+ * minor incompatible change: The --noprogrammer option is deprecated
+ in favor of the new --disable-debugger option, which is very similar.
+ (The major difference is that it takes effect at a slightly different
+ time at startup, causing handling of errors in --sysinit and
+ --userinit files will be affected differently.) The
+ SB-EXT:DISABLE-DEBUGGER and SB-EXT:ENABLE-DEBUGGER functions have
+ been added to allow this functionality to be controlled from ordinary
+ Lisp code. (ENABLE-DEBUGGER should help people like the Debian
+ maintainers, who might want to run non-interactive scripts to
+ build SBCL cores which will later be used interactively.)
+ * minor incompatible change: The LOAD function no longer, when given
+ a wild pathname to load, loads all files matching that pathname.
+ Instead, an error of type FILE-ERROR is signalled.
+
+changes in sbcl-0.7.6 relative to sbcl-0.7.5:
+ * bug fix: Floating point exceptions are treated much more
+ consistently on the x86/Linux and PPC/Linux platforms.
+ * Array initialization with :INITIAL-ELEMENT is now much faster for
+ cases when the compiler cannot open code the array creation, but
+ does know what the UPGRADED-ARRAY-ELEMENT-TYPE will be. General
+ array accesses have also seen a speed increase.
+ * bug fix: LOAD :IF-DOES-NOT-EXIST NIL now works when file type is
+ specified. (This was at the root of some bad interactions between
+ SBCL and ILISP: thanks to Gregory Wright for diagnosing this and
+ reporting the bug.)
+ * bug fix: Internal error arguments for undefined functions are now
+ computed correctly on the PPC/Linux platform.
+ * bug fix: Bad &REST syntax is now checked correctly. (thanks to
+ Raymond Toy's patch for CMU CL)
+ * Support for the Solaris 9 operating environment has been included
+ (thanks to Daniel Merritt)
+ * A very ugly but hopefully complete draft of the missing FFI chapter
+ of the manual has been created by reformatting the corresponding
+ CMU CL manual chapter into (currently very ugly and incoherent)
+ DocBook and bringing it up to date for SBCL behavior. Thus, the
+ manual is now essentially complete, at least by my extreme
+ once-and-only-once standards, whereby it's acceptable to refer to
+ the doc strings of SB-EXT functions as the primary documentation.
+ * The fasl file version number has changed again, due to cleanup of
+ (user-invisible) bitrotted stuff. (E.g. *!INITIAL-FDEFN-OBJECTS*
+ is no longer a static symbol.)
+
+changes in sbcl-0.7.7 relative to sbcl-0.7.6:
+ * An alpha-quality port to the parisc architecture running Linux,
+ based on the old CMUCL backend, has been made. This, even more so
+ than the other backends, should be considered still a work in
+ progress; known problems include that the Linux kernel in 64-bit
+ mode does not propagate the correct sigcontext structure to
+ userspace, and consequently SBCL on a parisc64 kernel will not
+ work yet.
+ * fixed bug 189: The compiler now respects NOTINLINE declarations for
+ functions declared in FLET and LABELS. (I.e. "LET conversion" is
+ suppressed.) Also now that the compiler is looking at declarations
+ in the environment, it checks optimization declarations as well,
+ and suppresses inlining when (> DEBUG SPEED).
+ * More fixes have been made to treatment of floating point exception
+ treatment and other Unix signals. In particular, floating point
+ exceptions no longer cause Bus errors on the SPARC/Linux platform.
+ * The detection and handling of control stack exhaustion (infinite
+ or very deeply nested recursion) has changed. Stack exhaustion
+ detection is now done by write-protecting pages at the OS level
+ and applies at all optimization settings; when found, a
+ SB-KERNEL:CONTROL-STACK-EXHAUSTED condition (subclass of
+ STORAGE-CONDITION) is signalled, so stack exhaustion can no longer
+ be caught using IGNORE-ERRORS.
+ * Bugs 65, 70, and 109 fixed: The compiler now preserves invariants
+ correctly when transforming recursive LABELS functions to LETs.
+ (thanks to Alexey Dejneka)
+ * Bug 48a./b. fixed: SYMBOL-MACROLET now refuses to bind symbols
+ that are names of constants or global variables.
+ * Bug fix: DEFINE-ALIEN-ROUTINE now declaims the correct FTYPE for
+ alien routines with docstrings.
+ * Bug 184 fixed: Division of ratios by the integer 0 now signals an
+ error of type DIVISION-BY-ZERO. (thanks to Wolfhard Buss and
+ Raymond Toy)
+ * Bug fix: Errors in PARSE-INTEGER are now of type PARSE-ERROR.
+ (thanks to Eric Marsden)
+ * Bug fix: COERCE to (COMPLEX FLOAT) of rationals now returns an
+ object of type (COMPLEX FLOAT). (thanks to Wolfhard Buss)
+ * Bug fix: The SPARC backend can now compile functions involving
+ LOGAND and stack-allocated arguments. (thanks to Raymond Toy)
+ * Bug fix: We no longer segfault on passing a non-FILE-STREAM stream
+ to a functions expecting a PATHNAME-DESIGNATOR.
+ * Bug fix: DEFGENERIC now enforces the ANSI restrictions on its
+ lambda lists. (thanks to Alexey Dejneka)
+ * Bug fix: changed encoding of PCL's internal MAKE-INSTANCE
+ functions so that EXPORTing the name of the class doesn't cause
+ MAKE-INSTANCE functions from earlier DEFCLASSes to get lost (thanks
+ to Antonio Martinez for reporting this)
+ * Bug 192 fixed: The internal primitive DATA-VECTOR-REF can now be
+ constant-folded without failing an assertion. (thanks to Einar
+ Floystad Dorum for reporting this)
+ * Bugs 123 and 165 fixed: array specializations on as-yet-undefined
+ types are now dealt with more correctly by the compiler.
+ * Minor incompatible change: COMPILE-FILE-PATHNAME now merges its
+ OUTPUT-FILE argument with its INPUT-FILE argument, resulting in
+ behaviour analogous to RENAME-FILE. This puts its behaviour more
+ in line with ANSI's wording on COMPILE-FILE-PATHNAME. (thanks to
+ Marco Antinotti)
+ * The fasl file version number has changed again. (because of the
+ bug fix involving the names of PCL MAKE-INSTANCE functions)
+
+changes in sbcl-0.7.8 relative to sbcl-0.7.7:
+ * A beta-quality port to the mips architecture running Linux,
+ based on the old CMUCL backend, has been made. It has been tested
+ on a big-endian kernel, and works sufficiently well to be able to
+ rebuild itself; it has not been tested in little-endian mode.
+ * fixed an inconsistency between gencgc.c and purify.c which made
+ dumping/loading .core files unreliable
+ * fixed bug 120a: The compiler now deals correctly with IFs where
+ the consequent is the same as the alternative, instead of
+ misderiving the return type. (thanks to Alexey Dejneka)
+ * fixed bug 113: Logical pathnames are now dumpable (the logical
+ host is resolved at load-time, throwing an error if it is not
+ found).
+ * fixed bug 174: FORMAT's error message is slightly clearer when a
+ non-printing character is used in a format directive.
+ * fixed several bugs in compiler checking of type declarations, i.e.
+ violations of the Python "declarations are assertions" principle
+ (thanks to Alexey Dejneka)
+ * fixed several bugs in PCL's error checking (thanks to Gerd
+ Moellmann)
+ * fixed bug: printing of FILE-ERROR (thanks to Antonio
+ Martinez-Shotton)
+ * fixed bug in compilation of functions as first class values
+ (thanks to Antonio Martinez-Shotton)
+ * The compiler's handling TYPE-ERRORs which it can prove will
+ inevitably happen at runtime has been cleaned up and corrected
+ in several ways. (thanks to Alexey Dejneka)
+ * improved argument type checking for various basic arithmetic
+ operations (MAX, +, LOGXOR, etc.) which have had so much TLC
+ lavished on them in the past that they can be compiled in many
+ ways in different special cases
+ * fixed bug 181: compiler checks validity of user supplied type
+ specifiers
+ * cleaned up code flushing in optimization: Function calls which
+ should signal errors for safety purposes (e.g. which ANSI says
+ should signal errors when their arguments are of incorrect type)
+ are no longer optimized away.
+ * added new extension: SB-DEBUG:BACKTRACE-AS-LIST
+ * incremented fasl file version number, because changes in the
+ implementation of sequence functions like COERCE caused
+ internal utility functions like COERCE-TO-SIMPLE-VECTOR (used
+ in old inline expansions) to become undefined. (Actually these
+ changes were later undone, so we might very well be binary
+ compatible with 0.7.7 after all, but leaving the version number
+ incremented seemed like the simplest and most conservative
+ thing to do.)
+
+changes in sbcl-0.7.9 relative to sbcl-0.7.8:
+ * minor incompatible change: The runtime (the Unix executable named
+ "sbcl") is now much pickier about the .core files it will load.
+ Essentially it now requires .core files to descend from the same
+ build (not just the same sources or LISP-IMPLEMENTATION-VERSION)
+ as the runtime does. (The intent is to prevent the crashes which
+ can occur, and which can even be reported as mysterious failures,
+ when people patch the sources or change the build parameters
+ without changing LISP-IMPLEMENTATION-VERSION, then mix and match
+ sbcl and .core files.)
+ * fixed bug: VALUES-LIST is no longer optimized away.
+ * fixed bug 142: The FFI conversion of C string values to Lisp
+ string values no longer conses excessively. (thanks to Nathan
+ Froyd porting Raymond Toy's fix to CMU CL)
+ * began to systematize and improve MOP conformance in PCL (thanks to
+ Nathan Froyd, Gerd Moellman and Pierre Mai):
+ ** SLOT-DEFINITION-ALLOCATION now returns :CLASS, not the class
+ itself;
+ ** GENERIC-FUNCTION-ARGUMENT-PRECEDENCE-ORDER is now implemented;
+ ** FINALIZE-INHERITANCE is now called on class finalization;
+ ** DOCUMENTATION and (SETF DOCUMENTATION) now have the correct
+ argument precedence order.
+ * fixed bug 202: The compiler no longer fails on functions whose
+ derived types contradict their declared type.
+ * DEFMACRO is implemented via EVAL-WHEN instead of IR1 translation,
+ so it can be non-toplevel.
+ * The fasl file version number has changed (because of the new
+ implementation of DEFMACRO).
+ * (mostly) fixed bugs 46b and 46c: sequence functions now check, in
+ safe code, that any length requirement by their type-specifier
+ argument is valid. The exceptions to this are described in bug
+ 213.
+ * fixed bugs 46h and 46i: TWO-WAY- and CONCATENATED-STREAM creation
+ functions now check the types of their inputs as required by ANSI.
+ * fixed bug 48c: SYMBOL-MACROLET signals PROGRAM-ERROR when an
+ introduced symbol is DECLAREd to be SPECIAL.
+ * fixed reading of (COMPLEX DOUBLE-FLOAT) literals from fasl files
+ * fixed bug: :COUNT argument to sequence functions may be negative
+ * fixed bug: body of DO-SYMBOLS may contain declarations
+ * fixed bug: PUSHNEW now evaluates its arguments from left to right
+ (reported by Paul F. Dietz, fixed by Gerd Moellman)
+ * fixed bug: PUSH, PUSHNEW and POP now evaluate a place given by a
+ symbol macro only once
+ * fixed printing of call frame when argument list is unavailable
+ * fixed bug: :ALLOW-OTHER-KEYS is an allowed keyword name
+ * compiler no longer signals WARNING on unknown keyword
+ :ALLOW-OTHER-KEYS
+
+changes in sbcl-0.7.10 relative to sbcl-0.7.9:
+ * Support for building SBCL for MIPS platforms running in
+ little-endian mode has now been checked in, and basic
+ functionality on said platforms verified.
+ * minor incompatible change: PCL now records the pathname of a file
+ in which methods and the like are defined, rather than its
+ truename.
+ * minor incompatible change: TRUENAME now considers the truename of
+ a file naming a directory to be the pathname with :DIRECTORY
+ component indicating that directory.
+ * minor incompatible change: a NAMED clause in the extended form of
+ LOOP no longer causes a BLOCK named NIL to surround the LOOP. The
+ reason for the previous behaviour is unclear.
+ * more systematization and improvement of CLOS and MOP conformance
+ in PCL (thanks to Gerd Moellman and Pierre Mai):
+ ** the standard ANSI CL generic function NO-NEXT-METHOD is now
+ implemented;
+ ** DEFINE-METHOD-COMBINATION no longer signals an error for
+ primary methods with no specializers;
+ ** the MOP generic function GENERIC-FUNCTION-DECLARATIONS is now
+ implemented;
+ ** the Readers for Class Metaobjects methods CLASS-DIRECT-SLOTS
+ and CLASS-DIRECT-DEFAULT-INITARGS have been implemented for
+ FORWARD-REFERENCED-CLASSes; error reporting on
+ CLASS-DEFAULT-INITARGS, CLASS-PRECEDENCE-LIST and CLASS-SLOTS
+ has been improved;
+ ** SXHASH on CLOS instances now uses a slot internal to the
+ instance to return different numbers on distinct instances,
+ while preserving the same return value through invocations of
+ CHANGE-CLASS;
+ ** DEFMETHOD signals errors when methods with longer incongruent
+ lambda lists are added to generic functions;
+ ** COMPUTE-CLASS-PRECEDENCE-LIST now has a method specialized on
+ CLASS, as specified in AMOP;
+ ** COMPUTE-SLOTS :AROUND now assigns locations sequentially based
+ on the order returned by the primary method for classes of
+ class STANDARD-CLASS;
+ ** DEFINE-METHOD-COMBINATION now works with the :ARGUMENTS option.
+ * fixed some bugs shown by Paul Dietz' test suite:
+ ** DOLIST puts its body in TAGBODY;
+ ** SET-EXCLUSIVE-OR sends arguments to :TEST function in the
+ correct order;
+ ** MULTIPLE-VALUE-SETQ evaluates side-effectful places before
+ value producing form;
+ ** if more variables are given to PROGV than values, extra
+ variables are bound and made to have no value;
+ ** NSUBSTITUTE on list arguments gets the right answer with
+ :FROM-END;
+ ** ELT signals an error of type TYPE-ERROR when the index argument
+ is not a valid sequence index;
+ ** LOOP signals (at macroexpansion time) an error of type
+ PROGRAM-ERROR when duplicate variable names are found;
+ ** LOOP supports DOWNTO and ABOVE properly; (thanks to Matthew Danish)
+ ** FUNCALL of special-operators now cause an error of type
+ UNDEFINED-FUNCTION;
+ ** PSETQ now works as required in the presence of side-effecting
+ symbol-macro places;
+ ** NCONC accepts any object as its last argument;
+ ** :COUNT argument to sequence functions may be BIGNUM; (thanks to
+ Gerd Moellman)
+ ** loop-for-as-package does not require a package to be explicitely
+ specified;
+ ** LOOP WITH now treats NIL in the d-var-spec correctly as an
+ ignored binding.
+ * fixed bug 166: compiler preserves "there is a way to go"
+ invariant when deleting code.
+ * fixed bug 172: macro lambda lists with required arguments after
+ &REST arguments now cause an error to be signalled. (thanks to
+ Matthew Danish)
+ * fixed Entomotomy PEEK-CHAR-WRONGLY-ECHOS-TO-ECHO-STREAM
+ bug. (thanks to Matthew Danish)
+ * fixed bug 225: STRING-STREAM is now a class. (reported by Gilbert
+ Baumann)
+ * fixed bug 136: CALL-NEXT-METHOD no longer gets confused when
+ arguments are lexically rebound. (thanks to Gerd Moellmann and
+ Pierre Mai)
+ * fixed bug 194: error messages are now more informative when there
+ is no primary method applicable in a call to a generic
+ function. (thanks to Gerd Moellmann)
+ * fixed bug in command line argument checking (thanks to Julian
+ Fondren)
+ * fixed bug in COUNT-IF, making it handle :FROM-END correctly
+ (thanks to Matthew Danish)
+ * incremented fasl file version number, because of the
+ SXHASH-related changes in the layout of CLOS data structures
+
+changes in sbcl-0.7.11 relative to sbcl-0.7.10:
+ * fixed bug 127: DEFSTRUCT now does not clobber old structure
+ accessors that are related by inheritance, as specified in the
+ :CONC-NAME section of the specification of DEFSTRUCT. (thanks to
+ Valtteri Vuorikoski)
+ * The compiler is now able to inline functions that were defined in
+ a complex lexical environment (e.g. inside a MACROLET).
+ * fixed bug in DESCRIBE, which now works on rank-0 arrays. (thanks
+ to Lutz Euler)
+ * Support for the upcoming FreeBSD-5.0 release has been included.
+ (thanks to Dag-Erling Smorgrav)
+ * fixed bug 219: DEFINE-COMPILER-MACRO no longer has compile-time
+ effect when it is not in a toplevel context.
+ * fixed bug 222: DEFMETHOD and SYMBOL-MACROLET interactions now
+ stand a better chance of being correct. (thanks to Gerd
+ Moellmann)
+ * fixed bug in COERCE, which now signals an error on coercing a
+ rational to a bounded real type which excludes the expected
+ answer.
+ * The compiler is now able to derive types more accurately from the
+ COERCE and COMPILE functions.
+ * fixed bug 223: functional binding is considered to be constant
+ only for symbols in the CL package.
+ * fixed bug 231: SETQ did not check the type of a variable being set
+ (reported by Robert E. Brown)
+ * A new optimization for MAKE-INSTANCE has been included, fixing
+ various bugs (including relating to :ALLOCATION :CLASS slots and
+ :DEFAULT-INITARGS over-eager evalueation). (thanks to Gerd
+ Moellmann)
+ * fixed some LOOP bugs revealed by Paul Dietz' test suite:
+ ** As required by ANSI, LOOP now disallows anonymous collection
+ clauses such as COLLECT I in conjunction with aggregate boolean
+ clauses such as THEREIS (= I 1);
+ ** LOOP now signals an error when any variable is reused in the
+ same loop (including the potentially useful construct analogous
+ to WITH A = 1 WITH A = (1+ A);
+ ** IT is only a special loop symbol within the first clause of a
+ conditional loop clause;
+ ** LOOP with a typed iteration variable over a hashtable now
+ signals a type error iff it should.
+ * fixed some other bugs revealed by Paul Dietz' test suite:
+ ** FILE-STREAM now names the class previously known as FD-STREAM;
+ ** in DEFSTRUCT, a bare :CONC-NAME (or a :CONC-NAME with no
+ argument) no longer signals an error;
+ ** likewise in DEFSTRUCT, :CONC-NAME NIL now respects the package
+ of the slot symbol, rather than using the current package
+ ((:CONC-NAME "") continues to intern the slot's name in the
+ current package);
+ * incremented fasl file version number, because of the incompatible
+ change to the DEFSTRUCT-DESCRIPTION structure, and again because
+ of the new implementation of DEFINE-COMPILER-MACRO.
+
+changes in sbcl-0.7.12 relative to sbcl-0.7.11:
+ * minor incompatible change: code processed by the "interpreter" or
+ EVAL now has a compilation optimization policy of (DEBUG 2)
+ (changed from (DEBUG 1)) to improve debuggability of interactive
+ development, and to allow the use of the debug RETURN command in
+ such code.
+ * an experimental implementation of the RETURN command for the
+ debugger has been included. (thanks to Frederik Kuivinen)
+ * fixed bug 62: constraints were not propagated into a loop.
+ * fixed bug in embedded calls of SORT (reported and investigated by
+ Wolfgang Jenkner).
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** printing and reading of arrays with some dimensions having
+ length 0 (thanks to Gerd Moellmann);
+ ** BOA constructor with &AUX argument without a default value does
+ not cause a type error;
+ ** CONSTANTP now returns true for all self-evaluating objects.
+
+changes in sbcl-0.7.13 relative to sbcl-0.7.12:
+ * incompatible packaging change: in line with Unix convention,
+ SBCL now looks for its core file in /usr/{local/,}lib/sbcl/sbcl.core
+ if it's not in $SBCL_HOME. It also sets SBCL_HOME to match.
+ * REQUIRE and PROVIDE are now optionally capable of doing something
+ useful. See the documentation string for REQUIRE.
+ * infrastructure for a managed SBCL contrib system: contributed
+ modules in this release include:
+ ** the ASDF system definition facility;
+ ** an interface to the BSD Sockets API;
+ ** an ACL-like convenience interface to the repl;
+ (thanks to Kevin Rosenberg)
+ ** an implementation of ROTATE-BYTE, with efficient implementation
+ on x86 hardware;
+ * fixed a bug in LOG, so that LOG of a rational argument near 1 now
+ gives a closer approximation to the right answer than previously.
+ (thanks to Raymond Toy)
+ * fixed bug 157: TYPEP, SUBTYPEP, UPGRADED-ARRAY-ELEMENT-TYPE and
+ UPGRADED-COMPLEX-PART-TYPE now take (ignored, in all situations)
+ optional environment arguments, as required by ANSI.
+ * fixed bugs in other functions taking environment objects, allowing
+ calls with an explicit NIL environment argument to be compiled
+ without error.
+ * fixed bug 228: primary return values from
+ FUNCTION-LAMBDA-EXPRESSION are either NIL or suitable for input to
+ COMPILE or FUNCTION.
+ * fixed a bug in DEFSTRUCT: predicates for :NAMED structures with
+ :TYPE will no longer signal errors on innocuous objects.
+ * fixed bug 231b: SETQ is better at respecting type declarations in
+ the lexical environment.
+ * fixed a bug in DEFCLASS: classes named by symbols with no or
+ unprintable packages can now be defined.
+ * fixed a bug in RESTART-BIND: The :TEST-FUNCTION option had been
+ carelessly renamed to :TEST-FUN. (thanks to Robert E. Brown)
+ * fixed compiler failure related to checking types of functions.
+ (reported by Robert E. Brown)
+ * the compiler is now much more consistent in its error-checking
+ treatment of bounding index arguments to sequence functions: in
+ (SAFETY 3) code, errors will be signalled in almost all cases if
+ invalid sequence bounding indices are passed to functions defined
+ by ANSI to operate on sequences.
+ * fixed a bug in the build procedure: documentation of SBCL-specific
+ packages is now preserved and available in the final Lisp image.
+ * lifted FDEFINITION lookup out of loops in the implementation of
+ many list operations. (thanks to Robert E. Brown)
+ * fixed a bug in the reader: the #n# reader macro now works for
+ objects of type STANDARD-OBJECT. (reported by Tony Martinez)
+ * the compiler is now aware that SYMBOL-FUNCTION returns a FUNCTION
+ and that READ-DELIMITED-LIST returns a LIST. (thanks to Robert
+ E. Brown and Tony Martinez respectively)
+ * PCL is now smarter about SLOT-VALUE, (SETF SLOT-VALUE) and
+ SLOT-BOUNDP: in particular, it is now able to optimize them much
+ better, and is now not vulnerable to having packages renamed.
+ Furthermore, a compliance bug has been fixed: SLOT-MISSING is now
+ always called when a slot is not present in an instance. (thanks
+ to Gerd Moellmann)
+ * fixed a bug related to CONCATENATED-STREAMs: PEEK-CHAR will no
+ longer signal an error on unreading a character following EOF on
+ the previous constituent stream. (thanks to Tony Martinez)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
+ not just nonnegative fixnums;
+ ** the logical bit-array operators such as BIT-AND now accept an
+ explicit NIL for their "opt-arg" argument (to indicate a
+ freshly-consed result bit-array);
+ ** ELT now signals an error on an invalid sequence index in safe
+ code;
+ ** the type system is now cleverer about negations of numeric
+ types, and consequently understands the BIGNUM and RATIO types
+ better;
+ ** the type system is now cleverer about the interaction between
+ INTEGER and RATIO types: while bugs still remain, many more
+ cases are accurately computed;
+ ** in TYPECASE, OTHERWISE now only introduces an otherwise-clause
+ if it is in the last clause;
+ ** CONSTANTLY now correctly returns a side-effect-free function in
+ all cases;
+ ** DECLARE is no longer treated as a special-operator; in
+ particular, SPECIAL-OPERATOR-P no longer returns T for DECLARE;
+ * incremented fasl file version number due to the change in the
+ DEFSTRUCT-SLOT-DESCRIPTION structure.
+
+changes in sbcl-0.7.14 relative to sbcl-0.7.13:
+ * a better implementation of SXHASH on (simple) bit vectors,
+ measured both in execution speed and in distribution of results
+ over the positive fixnums, has been installed. Likewise, a better
+ implementation of EQUAL for simple bit vectors is now available.
+ * fixed CEILING optimization for a divisor of form 2^k.
+ * fixed bug 240 (emitting extra style warnings "using the lexical
+ binding of the symbol *XXX*" for &OPTIONAL arguments). (reported
+ by Antonio Martinez)
+ * fixed SXHASH, giving different results for NIL depending on type
+ declarations (SYMBOL or LIST). (thanks to Gerd Moellmann)
+ * fixed bug in DEFPARAMETER and DEFVAR: they could assign a lexical
+ variable. (found by Rolf Wester)
+ * SBCL does not ignore type declarations for special
+ variables. (reported by rif on c.l.l 2003-03-05)
+ * some bug fixes in contrib/sb-aclrepl/
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** a bug in the CONS type specifier, whereby the CAR and CDR
+ types got intertwined, has been fixed;
+ ** the type system is now able to reason about the interaction
+ between INTEGER and RATIO types more completely;
+ ** APPEND, [N]REVERSE and NRECONC check that those their
+ arguments, which must be proper lists, are really so;
+ ** An array specialized to be unable to hold elements has been
+ implemented, as required -- yes, really -- by ANSI;
+ ** GETF and GET-PROPERTIES throw a TYPE-ERROR, not a SIMPLE-ERROR,
+ on malformed property lists;
+
+changes in sbcl-0.8alpha.0 relative to sbcl-0.7.14
+ * experimental native threads support (on x86 Linux >=2.4 only).
+ This is not compiled in by default: you need to add :SB-THREAD to
+ the target features. See the "Beyond ANSI" chapter of the manual
+ for details.
+ * fix for longstanding nonANSIism: The old distinction between
+ CL:CLASS objects and SB-PCL:CLASS objects has been eliminated.
+ The return value from CL:FIND-CLASS is now a CLOS class, and
+ likewise that of CL:CLASS-OF; CL:BUILT-IN-CLASS,
+ CL:STRUCTURE-CLASS and CL:STANDARD-CLASS name CLOS classes.
+ * An interface to the MetaObject Protocol, as described in Kiczales,
+ des Rivieres and Bobrow's "The Art of the Metaobject Protocol",
+ MIT Press, 1991, is available from the SB-MOP package.
+ * incompatible change: the SB-PCL package should now be considered
+ a private implementation detail, and no longer a semi-private MOP
+ interface.
+ * minor incompatible change: due to rearrangement for threads, the
+ control stack and binding stack are now allocated at arbitrary
+ addresses instead of being hardcoded per-port. Users affected by
+ this probably have to be doing advanced things with shared
+ libraries, and will know who they are.
+ * minor incompatible change: Previously, all --eval forms used were
+ processed with READ before any of them were processed with EVAL.
+ Now each --eval form is processed with both READ and EVAL before
+ the next --eval form is processed. (Thus package operations like
+ sbcl --eval "(defpackage :foo)" --eval "(print 'foo::bar)" now
+ work as the user might reasonably expect.)
+ * minor incompatible change: *STANDARD-INPUT* is now only an
+ INPUT-STREAM, not a BIDIRECTIONAL-STREAM. (thanks to Antonio
+ Martinez)
+ * minor incompatible change: Y-OR-N-P is now character-oriented,
+ not line oriented. Also, YES-OR-NO-P now works without errors.
+ (thanks to Antonio Martinez)
+ * sb-aclrepl module improvements: an integrated inspector, added
+ repl features, and a bug fix to :trace command.
+ * Known functions, which cannot be open coded by the backend, are
+ considered to be able to check types of their arguments. (fixing
+ a bug report by Nathan J. Froyd)
+ * fixed a bug in computing method discriminating functions: It is
+ now possible to define methods specialized on classes which have
+ forward-referenced superclasses. (thanks to Gerd Moellmann)
+ * fixed evaluation order in optional entries (reported by Gilbert
+ Baumann)
+ * SB-MOP:ENSURE-CLASS-USING-CLASS now takes its arguments in the
+ specified-by-AMOP order of (CLASS NAME &REST ARGS &KEY).
+ * SB-MOP:COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes the
+ required-by-AMOP NAME argument, as well as CLASS and
+ DIRECT-SLOT-DEFINITIONS. (thanks to Kevin Rosenberg)
+ * fixed bug 20: DEFMETHOD can define methods using names that are
+ not the proper names of classes to designate class specializers.
+ * bug fix: INTERACTIVE-STREAM-P now works on streams associated with
+ Unix file descriptors, instead of blowing up. (thanks to Antonio
+ Martinez)
+ * Garbage collection refactoring: user-visible change is that a
+ call to the GC function during WITHOUT-GCING will not do garbage
+ collection until the end of the WITHOUT-GCING. If you were doing
+ this you were probably losing anyway.
+ * fixed bug in MEMBER type: (MEMBER 0.0) is not the same as
+ (SINGLE-FLOAT 0.0 0.0), because of the existence of -0.0 which is
+ TYPEP the latter but not the former.
+ * The compiler issues a full WARNING for calls to undefined functions
+ with names from the CL package.
+ * MAP-INTO for a vector destination is open coded. (reported by
+ Brian Downing on c.l.l)
+ * bug fix: the long form of DEFINE-METHOD-COMBINATION now accepts a
+ documentation string.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** COPY-ALIST now signals an error if its argument is a dotted
+ list.
+ ** Condition slots are now accessed more correctly in the presence
+ of multiple initargs for a given slot.
+ ** The USE-VALUE, CONTINUE and STORE-VALUE functions now correctly
+ exclude restarts of the same name associated with a different
+ condition.
+ ** DEFCLASS of forward-referenced classes with another
+ forward-referenced class in the superclasses list no longer
+ causes an error.
+ ** Condition slots are now initialized once each, not multiple
+ times. (thanks to Gerd Moellmann)
+ ** CONVERT-MORE-CALL failed on a lambda list (&KEY). (thanks to
+ Gerd Moellmann)
+ ** &WHOLE and &REST arguments in macro lambda lists are patterns.
+ ** NSET-EXCLUSIVE-OR does not return extra elements when its
+ arguments contain duplicated elements.
+ ** RESTART-CASE understands local macros.
+ ** RESTART-CASE associates exactly its own restarts with a condition.
+ ** ENDP in safe mode checks its argument to be of type LIST.
+ ** COPY-SYMBOL in a threaded build no longer fails when the symbol
+ in question is unbound.
+ ** Optimized MAKE-INSTANCE functions no longer cause internal
+ assertion failures in the presence of duplicate initargs.
+ ** SLOT-MAKUNBOUND returns the instance acted upon, not NIL.
+ ** Side-effectful :DEFAULT-INITARGS have their side-effects
+ propagated even in the ctor optimized implementation of
+ MAKE-INSTANCE.
+ ** :ALLOW-OTHER-KEYS NIL is now accepted in an initarg list.
+
+changes in sbcl-0.8.0 relative to sbcl-0.8alpha.0
+ * 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).
+ * 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. (Currently it does not work with high DEBUG level.)
+ * minor incompatible change: VALUES declaration is disabled.
+ * When issuing notes, the compiler now signals a condition of type
+ SB-EXT:COMPILER-NOTE, and provides an associated MUFFLE-WARNING
+ restart for use in user handlers. It is expected that the
+ COMPILER-NOTE condition will eventually become a condition
+ supertype to a hierarchy of note types, which will then be
+ handleable in a similar fashion. However, at the moment, no such
+ note subtypes yet exist. (SB-INT:SIMPLE-COMPILER-NOTE exists,
+ but it's an implementation detail, not a classification for the
+ purpose above.)
+ * 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).
+ * A short form of VALUES type specifier has ANSI meaning (it has
+ increased the number of situations when SBCL cannot perform type
+ checking).
+ * 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)
+ * fixed bug 246: increased compilation speed of long
+ MULTIPLE-VALUE-BIND (and likewise of NTH-VALUE with a constant
+ integer argument)
+ * 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 now better at handling symbol macros.
+ * bug fix: There is no longer an internal implementation type named
+ CL:LENGTH. (reported by Raymond Toy)
+ * bug fix: In macro-like defining macros/special operators the
+ implicit block does not enclose the lambda list.
+ * fixed bugs 10 and 43: Bare VALUES, AND, OR and MEMBER symbols (not
+ enclosed in parentheses) are not suitable as type specifiers, and
+ their use properly signals an error now.
+ * bug fix: An argument count mismatch for a type specifier in code
+ being compiled no longer causes an unhandled error at compile
+ time, but signals a compile-time warning.
+ * fixed simple vector readable printing
+ * bug fix: DESCRIBE takes more care over whether the class
+ precedence list slot of a class is bound before accessing it.
+ (reported by Markus Krummenacker)
+ * bug fix: FORMATTER can successfully compile pretty-printer format
+ strings which use variants of the ~* directive inside.
+ * bug fix: SEARCH now applies its TEST predicate to the elements of
+ the arguments in the correct order. (thanks to Wolfhard Buss)
+ * fixed bug 235b: The compiler uses return types of MAPCAR and friends
+ in type inference. (thanks to Robert E. Brown)
+ * bug fix: Reading in symbols with an explicit package name of ""
+ (e.g. '||::FOO) now works correctly. (reported by Henrik Motakef)
+ * 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
+ five 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.
+ ** DEFCLASS only redefines the class named by its class-name
+ argument if that name is the proper name of the class;
+ otherwise, it creates a new class.
+ ** SLOT-UNBOUND now correctly initalizes the CELL-ERROR-NAME slot
+ of the UNBOUND-SLOT condition to the name of the slot.
+ ** (SETF (AREF bv 0) ...) did not work for bit vectors.
+ ** SLOT-UNBOUND and SLOT-MISSING now have their return values
+ treated by SLOT-BOUNDP, SLOT-VALUE, (SETF SLOT-VALUE) and
+ SLOT-MAKUNBOUND in the specified fashion.
+
+changes in sbcl-0.8.2 relative to sbcl-0.8.1:
+ * fixed bug 148: failure to inline-expand a local function left
+ garbage, confusing the compiler.
+ * fixed bugs 3cd: structure slot readers perform type check if the
+ slot can have an invalid value (i.e. it is either not initialized
+ or can be written with a less specific slot writer).
+ * bug fix: the compiler now traps array references to elements off
+ the end of an array; previously, the bounds checking in some
+ circumstances could go off-by-one.
+ * improved MACHINE-VERSION, especially on Linux (thanks to Lars
+ Brinkhoff)
+ * type declarations for array element types now obey the description
+ on the CLHS page "Declaration TYPE", as per discussions on
+ sbcl-help around 2003-05-08. This means that a declaration
+ (TYPE (ARRAY FOO) BAR) means that, within the scope of the
+ declaration, all references to BAR will be asserted or assumed
+ (with THE, so dependent on compiler policy) to involve objects of
+ type FOO. Note that no such declaration is implied in
+ (MAKE-ARRAY .. :ELEMENT-TYPE 'FOO).
+ * declared types of functions from the "Conditions"
+ chapter. (reported by Paul Dietz)
+ * bug fix: CERROR accepts a function as its first argument.
+ * bug fix: NTH an NTHCDR accept a bignum as index
+ arguments. (reported by Adam Warner)
+ * optimization: character compare routines now optimize comparing
+ against a constant character. (reported by Gilbert Baumann)
+ * bug fix: (SETF AREF) on byte-sized-element arrays with constant index
+ argument now works properly on the MIPS platform.
+ * fixed compiler failure on (TYPEP x '(NOT (MEMBER 0d0))).
+ * repeated evaluation of the same DEFSTRUCT, a slot of which is
+ declared to have a functional type, does not cause an error
+ anymore.
+ * fixed bug: sometimes MAKE-INSTANCE did not work with classes with
+ many :DEFAULT-INITARGS. (reported by Istvan Marko)
+ * fixed bug: if last continuation of a deleted block has a
+ destination, this destination should be deleted too. (reported by
+ ohler on #lisp)
+ * fixed a bug in the bootstrap process: the host compiler's values
+ of ARRAY-DIMENSION-LIMIT and ARRAY-TOTAL-SIZE-LIMIT no longer leak
+ into the newly-built SBCL. (reported by Eric Marsden on #lisp,
+ test case from Patrik Nordebo)
+ * improved the ability of the disassembler on the PPC platform to
+ provide helpful disassembly notes.
+ * SB-MOP:CLASS-PROTOTYPE on built-in-classes returns an instance of
+ the class in more cases than previously.
+ * bug fix: FILE-POSITION now understands :START and :END for
+ STRING-INPUT-STREAMs. (thanks to Nikodemus Siivola)
+ * bug fix: (SIGNED-BYTE 8) streams no longer return (UNSIGNED-BYTE
+ 8) data. (thanks to David Lichteblau)
+ * bug fix: it is possible to add a method to a generic function
+ without lambda list.
+ * bug fix: reader failed to signal END-OF-FILE inside an
+ object representation. (reported by Nikodemus Siivola)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** LAST and [N]BUTLAST should accept a bignum.
+ ** condition slot accessors are methods.
+ ** (VECTOR NIL) is a subtype of STRING.
+
+changes in sbcl-0.8.3 relative to sbcl-0.8.2:
+ * bug fix: WITH-OUTPUT-TO-STRING (and MAKE-STRING-OUTPUT-STREAM) now
+ accept and act upon their :ELEMENT-TYPE keyword argument.
+ (reported by Edi Weitz)
+ * bug fix: FILE-POSITION now accepts position designators up to
+ ARRAY-DIMENSION-LIMIT or the extreme of the off_t range, whichever
+ is the greater. (thanks to Patrik Nordebo)
+ * bug fix: MAKE-ARRAY ignored :INITIAL-CONTENTS NIL. (reported by
+ Kalle Olavi Niemitalo)
+ * bug fix: the CLASS-PROTOTYPE of the GENERIC-FUNCTION class is now
+ printable. (reported by Eric Marsden)
+
+planned incompatible changes in 0.8.x:
+ * (not done yet, but planned:) When the profiling interface settles
+ down, 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.)
+ * (not done yet, but planned:) Inlining can now be controlled the
+ ANSI way, without MAYBE-INLINE, since the idiom
(DECLAIM (INLINE FOO))
(DEFUN FOO (..) ..)
(DECLAIM (NOTINLINE FOO))
(DEFUN BAR (..) (FOO ..))
(DEFUN BLETCH (..) (DECLARE (INLINE FOO)) (FOO ..))
- now does what ANSI says it should. The CMU-CL-style
- SB-EXT:MAYBE-INLINE declaration is now deprecated and ignored.
