(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: + * SBCL now builds and runs on MacOS X (version 10.2), or perhaps + more accurately, on the Darwin kernel running on PowerPC hardware. + (thanks to Brian Mastenbrook, Pierre Mai and Patrik Nordebo) + * Compiler code deletion notes now signal a condition of type + SB-EXT:CODE-DELETION-NOTE (a subtype of SB-EXT:COMPILER-NOTE) with + an associated MUFFLE-WARNING restart. + * The compiler now performs limited argument count validation of + constant format strings in FORMAT, and where appropriate in ERROR, + CERROR and WARN. (thanks to Gerd Moellmann) + * New ASDF-INSTALL contrib can be used for automatic download and + installation of third-party Lisp code from CCLAN or other sites + via CLiki. + * Threaded builds (:SB-THREAD) now support SB-THREAD:INTERRUPT-THREAD, + which forces another thread to execute a function supplied by the + caller. + * bug 75 fix: WITH-OUTPUT-TO-STRING (and MAKE-STRING-OUTPUT-STREAM) + now accept and act upon their :ELEMENT-TYPE keyword argument. + (reported by Martin Atzmueller, 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) + * bug fix in sb-posix: mmap() now works on systems with a 64-bit + off_t, including Darwin and FreeBSD. (thanks to Andreas Fuchs) + * x86 bug fix in control stack exhaustion checking: now shows backtrace + * bug fix in WITH-TIMEOUT: now the body can have more than one form. + (thanks to Stig Sandoe) + * bug fix in READ-SEQUENCE: READ-SEQUENCE following PEEK-CHAR or + UNREAD-CHAR now correctly includes the unread character in the + target sequence. (thanks to Gerd Moellmann) + * bug fix in threaded builds: the system can now be suspended and + resumed by shell job control with minimal disruption. + * bug fixes in times and timezones >2038AD + * better handling of "where is GNU make?" problem in build scripts + (thanks to Nikodemus Siivola) + * new optimization: inside a named function any reference to a + function with the same name is considered to be a self-reference; + this behaviour is controlled with SB-C::RECOGNIZE-SELF-CALLS + optimization quality. + * new optimization on x86: logical functions and + now have + optimized (UNSIGNED-BYTE 32) versions, which are automatically + used when the result is truncated to 32 bits. + * VALUES declaration is partially enabled. + * fixes in SB-GROVEL (thanks to Andreas Fuchs) + * fixed some bugs revealed by Paul Dietz' test suite: + ** The system now obeys the constraint imposed by + UPGRADED-ARRAY-ELEMENT-TYPE that the upgraded array element + types form a lattice under type intersection. + ** FFLOOR, FTRUNCATE, FCEILING and FROUND work with integers. + ** ASSOC now ignores NIL elements in an alist. + ** CEILING now gives the right answer with MOST-NEGATIVE-FIXNUM + and (1+ MOST-POSITIVE-FIXNUM) answers. + ** The addition of a method with invalid qualifiers to a generic + function does not cause an error to be signalled immediately; + a warning is signalled, and the error is generated only on + calling the generic function. + * changed .fasl file version number, in part to add type codes for + new array subtypes UNSIGNED-BYTE 7, 15, 29, and 31 mandated by + obscure ANSI requirements + +changes in sbcl-0.8.4 relative to sbcl-0.8.3: + * fixed compiler performance when processing loops with a step >1; + * bug fix: DOCUMENTATION now retrieves generic function + documentation. Also, DOCUMENTATION and (SETF DOCUMENTATION) + support has been systematized, and now supports the methods + specified by ANSI, along with a default method and a method for + slot documentation. (reported by Nathan Froyd) + * bug fix: effective methods associated with a generic function are + no longer cached over a change of that generic function's method + combination. (reported by Andreas Fuchs) + * bug fix: RUN-PROGRAM now does not fail if some element in $PATH + names a non-existent directory. (thanks to Andreas Fuchs) + * optimization: restored some effective method precomputation in + CLOS (turned off by an ANSI fix in sbcl-0.8.3); the amount of + precomputation is now tunable. + * optimization: compiler-internal data structure use has been + reviewed, and changes have been made that should improve the + performance of the compiler by about 20%. + * microoptimization: the compiler is better able to make use of the + x86 LEA instruction for multiplication by constants. + * bug fix: in some situations compiler did not report usage of + generic arithmetic in (SPEED 3) policy. + 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
