(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 + ** 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.) - ?? TRACE :ENCAPSULATE T now attaches a more informative debug - name to its wrapper function objects than it used to + +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 + . + * 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 "AB") returns + |AB|, instead of A as it used to. + +changes in sbcl-0.7.5 relative to sbcl-0.7.4: + * SBCL now runs on the Tru64 (aka OSF/1) operating system on the + Alpha architecture. + * SBCL now builds with OpenMCL (version 0.12) as the + cross-compilation host; also, more progress has been made toward + bootstrapping under CLISP. + * bug 140 fixed: redefinition of classes with different supertypes + is now reflected in the type hierarchy. (thanks to Pierre Mai) + * 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: more-closely-ANSI CHANGE-CLASS function, now + accepting initargs. (thanks to Espen Johnsen and Pierre Mai) + * bug 179 fixed: DIRECTORY can now deal with filenames with pattern + characters in them. + * 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 name --disable-debugger option, which takes + effect at a slightly different time at startup (so that e.g. + 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. planned incompatible changes in 0.7.x: * When the profiling interface settles down, maybe in 0.7.x, maybe
