(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: + * minor incompatible change: PCL now records the pathname of a file + in which methods and the like are defined, rather than its + truename. + * 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; + * 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; + * 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) + planned incompatible changes in 0.7.x: * When the profiling interface settles down, maybe in 0.7.x, maybe later, it might impact TRACE.
