* 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.
- * HOST-NAMESTRING on physical pathnames now returns a string that is
- valid as a host argument to MERGE-PATHNAMES and to MAKE-PATHNAME.
+ * 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)
+ * fixed some more 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;
+ * incremented fasl file version number, because of the incompatible
+ change to the DEFSTRUCT-DESCRIPTION structure.
