It's + somewhat counter to the intent of the protocol, I (CSR) think, and + additionally it just doesn't work in SBCL as currently + implemented, thanks to optimizations (that are always valid for + the other three SLOT-VALUEish functions, but not for the setter). + * bug fix: unparsing logical pathnames with :NAME :WILD :TYPE NIL + failed with a type error.

Now user calls to + FINALIZE-INHERITANCE finalize just the one class, and calls by the + system return before any subclasses are finalized. + * minor incompatible change: The reader no longer ignores errors + regarding non-existent packages in #+ and #- feature tests. + * new feature: command line options --no-sysinit, --no-userinit to + inhibit loading the corresponding init files + * new feature: add a generic function SOCKET-SEND to SB-BSD-SOCKETS, + for sending data through UDP sockets (thanks to François-René Rideau) + * minor incompatible change: SIGPIPE is ignored and "Broken pipe" + error is signalled instead (thanks to François-René Rideau) + * minor incompatible change: Error signalling behaviour of lexical + operations violating package locks has changed slightly. Refer to + documentation on package locks for details. + * enhancement: EVAL can process IF-expressions without resorting to the + compiler. + * bug fix: Some operations involving SIN, COS, or TAN weren't being + constant-folded properly due to missing out-of-line functions. + (reported by Mika Pihlajamäki) + * bug fix: LISTEN sometimes returned T even in cases where no data was + immediately available from the stream + * fixed bug: types of the last two arguments to SET-SYNTAX-FROM-CHAR + were reversed. (reported by Levente Mészáros) + * fixed bug: Tests for the (VECTOR T) type gave the wrong answer + when given a vector displaced to an adjustable array. (reported + by Utz-Uwe Haus) + * bug fix: derivation of float boundaries from numbers outside the + appropriate float range (reported by John Wiseman) + * bug fix: MAKE-LOAD-FORM-SAVING-SLOTS accepts en empty slot name + list. + * bug fix: precomputing cache entries for generic functions with + some subclasses of specializers as yet invalid does not attempt to + fill a cache line with a negative offset. (reported by Levente + Mészároz) + * improvements to DOCUMENTATION for TYPE and STRUCTURE doc-types: + allow condition class objects as arguments to DOCUMENTATION and + (SETF DOCUMENTATION); only find and set documentation for + structure names for the STRUCTURE doc-type.

(reported by + Pascal Costanza) + * optimization: calling functions via constant symbols -- as in + (FUNCALL 'FOO) -- is now roughly as efficient as calling them + via the function object as in (FUNCALL #'FOO). + * optimization: on x86 and x86-64, the calling convention for the + case of dealing with an unknown number of values has been altered + to be friendlier to the prediction heuristics implemented, + particularly with reference to CALL and RET pairing.

This feature is not currently supported on all SBCL + platforms. (thanks to James Bielman and NIIMI Satoshi) + * new feature: a generational or ephemeral garbage collector is now + the default on the PowerPC platform (both Linux and Darwin). The + old Cheney (stop and copy) collector is a build-time option. + (thanks to Cyrus Harmon, after Raymond Toy) + * minor incompatible change: the method by which SBCL finds its + contributed modules has changed; it no longer relies on symbolic + links from an $SBCL_HOME/systems directory, but searches directly + in the subdirectories of $SBCL_HOME. + * enhancement: the dynamic heap size on the Linux/PPC platform is + markedly larger, even using the older Cheney garbage collector. + * fixed bug #399: full call to DATA-VECTOR-REF in accesses to + certain complicated string types. (reported by Gary King) + * fixed bug: STRING-TO-OCTETS and OCTETS-TO-STRING did not convert + character codes. (thanks to Yaroslav Kavenchuk and Ivan Boldyrev) + * fixed bug: DOCUMENTATION on structures no longer signals an + error if no structure type of the right name exists. (reported by + Glenn Ehrlich) + * fixed bug: compiled calls to MAKE-INSTANCE where there is an + applicable non-standard primary or :AROUND method on + INITIALIZE-INSTANCE or SHARED-INITIALIZE and a non-keyword initarg + no longer cause unbound variable errors. (reported by Kevin Reid) + * fixed bug: metacircle resolution in cases where methods have slots + added before the slots from STANDARD-METHOD. (reported by Jean + Bresson) + * fixed bug: the Power PC assembly code for calling into lisp + sometimes computed its return address wrongly (depending on the + 15th bit of the address, fixed at link time). This used to + manifest itself in a segmentation violation while building PCL. + (reported by Kevin Rosenberg, Eric Marsden, Lars Brinkhoff and + many others over the years) + * fixed bug: ROOM no longer reports silly numbers for stack usage if + the stack pointer (treated as a signed integer) is negative. + (thanks to Peter van Eynde) + +changes in sbcl-0.9.9 relative to sbcl-0.9.8: + * new platform: experimental support for the Windows operating + system has been added.

(thanks to NIIMI Satoshi) + +changes in sbcl-0.9.8 relative to sbcl-0.9.7: + * minor incompatible change: (SETF CLASS-NAME) and (SETF + GENERIC-FUNCTION-NAME) are generic functions once more (reverting + the change in the 0.9.7 release). (SETF CLASS-NAME) is specified + by ANSI as a generic function, and for consistency (SETF + GENERIC-FUNCTION-NAME) is treated likewise. + * fixed bug #233.b: make constraint propagation notice when a variable + value is changed after it is referenced but before it is used + * fixed bug #296: no more arbitrary behaviour from filenames with + odd characters as --load arguments. (reported by Adam Warner) + * fixed bug #390: :CHARACTER-SET pathname components now work as + expected. (reported by Tim Daly Jr) + * fixed bug #391: complicated :TYPE intersections in slot + definitions no longer cause an error in PCL internals. + * fixed bug #392: plugged a hole in the obsolete-instance protocol. + * bug fix: FILE-STRING-LENGTH is now external-format sensitive, + returning the number of octets which would be written to the + file-stream. (thanks to Robert J. Macomber) + * bug fix: the SB-SIMPLE-STREAMS contrib passes external-format + arguments to the internal stream functions. (thanks to David + Lichteblau) + * bug fix: stack exhaustion is now handled on the x86/SunOS + platform. (thanks to Daisuke Homma) + * bug fix: more accurate ROOM results on GENCGC platforms + * optimization: improved type inference for arithmetic-for + index variables in LOOP + * optimization: faster floating-point SQRT on x86-64 + * fixed some bugs revealed by Paul Dietz' test suite: + ** DOCUMENTATION returns NIL instead of "" for method combinations + that don't have a docstring + +changes in sbcl-0.9.7 relative to sbcl-0.9.6: + * minor incompatible change: (SETF CLASS-NAME) and (SETF + GENERIC-FUNCTION-NAME) are no longer generic functions, and + therefore are not customizeable by user code (as seems to be at + least permitted and maybe required by AMOP). As a consolation, + however, the SBCL implementation of these functions now calls + REINITIALIZE-INSTANCE as specified by AMOP. + * bug fix: slot-definition documentation is propagated as per ANSI + 7.6.2 to EFFECTIVE-SLOT-DEFINITIONS. + COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION + argument, as do eslotd initialization methods. (from Pascal + Costanza's "Closer" project) + * bug fix: REINITIALIZE-INSTANCE on generic functions calls + COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as + specified by AMOP. + * bug fix: it is now possible to have more than one subclass of + STANDARD-GENERIC-FUNCTION without causing stack overflow. + (reported by Bruno Haible, Pascal Costanza and others) + * bug fix: the dependent update protocol now works for generic + functions. (thanks to Gerd Moellmann; reported by Bruno Haible + and Pascal Costanza) + * bug fix: condition-class instances corresponding to + DEFINE-CONDITION forms are now created eagerly. (reported by + Kalle Olavi Niemitalo on comp.lang.lisp) + * bug fix: floating point printing is more accurate in some + circumstances. (thanks to Simon Alexander) + * bug fix: *COMPILE-FILE-PATHNAME* now contains the user's pathname + merged with *DEFAULT-PATHNAME-DEFAULTS*. + * bug fix: callbacks on OS X now preserve stack-alignment. + (thanks to Cyrus Harmon) + * enhancement: the x86-64 disassembler is much better at + disassembling SSE instructions.

(reported by Matthew D Swank on comp.lang.lisp) + * optimization: non-open coded uses of numeric comparison operators + (e.g. >) no longer cons when called with more than one parameter + on platforms supporting dynamic-extent allocation. + * enhancement: saving cores with foreign code loaded is now supported + on MIPS/Linux in addition to the previously supported platforms. + * bug fix: FIND-RESTART now tests for activity, not applicability when given + a restart object as identifier. (reported by Helmut Eller for CMUCL) + * bug fix: division by zero in sb-sprof when no samples were collected + * bug fix: a race when a slow to arrive sigprof signal killed sbcl + * bug fix: asdf-install uses CRLF as required by the HTTP spec. + (thanks to Alexander Kjeldaas) + * new feature: ignoring the return values of destructive functions + like NREVERSE signals a compile-time style-warning. + (thanks to Kevin Reid) + * new feature: the alignment of alien structure fields can be + explicitly specified.
