changes in sbcl-1.2.9 relative to sbcl-1.2.8:
* minor incompatible change and bug fix: unboxed numeric constants
on x86oids are arranged in memory differently, and the disassembler
does not show them separately in DISASSEMBLE, but does
if DISASSEMBLE-CODE-COMPONENT is used. (lp#1421987)
* optimization: The compiler's treatment of type specifiers makes
it slightly faster and more memory-efficient. Portable code
should be indifferent to this change, however, users of
SB-INTROSPECT:FUNCTION-TYPE might notice that (MEMBER T NIL)
and (MEMBER NIL T) are both internally collapsed to the former,
so that the latter can never be obtained as part of an FTYPE.
* optimization: a TYPEP call in which the second argument is not a
QUOTE form but nevertheless recognized as a compile-time constant
might open-code the test. One scenario for this involves backquote,
such as (TYPEP x `(my-type ,some-arg)). Code which relied upon
deferring until runtime should declare (NOTINLINE TYPEP).
[Due to the sematic constraints of DEFTYPE etc in in CLHS 3.2.2.3,
code requiring delayed evaluation could be unportable though.]
* enhancement: unused variables at the top-level are now reported.
(lp#492200)
* bug fix: DEFCLASS handles cyclic {super,meta}class relations better
(lp#1418883)
* bug fix: compiler no longer signals an error when compiling certain
function calls. (lp#1416704, lp#404441, lp#1417822, lp#1234919)
* bug fix: compiler doesn't stumble on a LOGIOR transform. (lp#1389433)
* bug fix: more robust debugger and backtraces. (lp#1413850, lp#1099500,
lp#1412881, lp#945261, lp#1419205, lp#1409402)
* bug fix: files larger than 4GB can now be compiled.
* bug fix: x86 truncated results from 64-bit foreign functions to 32 bits.
* bug fix: file-position didn't work on large files on win32. (lp#1271545)
* bug fix: callbacks from foreign threads can work without enabling
sb-safepoint.
* bug fix: sb-introspect:function-lambda-list works properly on interpeted
macros. (lp#1387404)
* bug fix: ADJUST-ARRAY properly handles non-adjustable arrays. (lp#886418)
* bug fix: compiler no longer fails to dump a multidimensional array
constant involving a circular reference to itself
* bug fix: conditional and nested DX allocation no longer confuse the
compiler in STACK analysis. (lp#1044465)
* bug fix: sb-rotate-byte constant folding bug fixed. (lp#1423682)
changes in sbcl-1.2.8 relative to sbcl-1.2.7:
* enhancement: better error and warning messages. (lp#1314767, lp#736383)
* enhancement: backtrace for invalid argument count produces the exact
supplied arguments including the extra ones, on x86, x86-64 and ARM.
* enhancement: a STYLE-WARNING is signaled for DEFSTRUCT accessors which
are used before the structure is defined; similarly for the predicate.
* optimization: FORMAT NIL with only ~a and string arguments is transformed
into CONCATENATE.
* optimization: POSITION and FIND when inlined into code that is compiled
with qualities of safety < 2 and speed > space will no longer signal
an error on circular lists, but will potentially loop forever if given
no :END constraint. As was always the case, calls that are not inlined
are safe regardless of lexical policy.
* bug fix: CLOS methods compiled with (OPTIMIZE (DEBUG 0))
no longer cause debugger failure when printing a backtrace
* bug fix: more resilience to deleted code. (lp#1308328, lp#1390544)
* bug fix: the CLHS example of MAKE-LOAD-FORM involving TREE-WITH-PARENT
did not work, and now it does.
changes in sbcl-1.2.7 relative to sbcl-1.2.6:
* optimization: returning constant values refers to preboxed constants
more reliably. (lp#1398785)
* enhancement: a STYLE-WARNING is produced if a compiler-macro is defined
for a function after at least one ordinary (not inlined) call to that
function was compiled, indicating a likely compilation order problem.
Likewise a warning ensues if a call is compiled to a function
that is subsequently proclaimed INLINE.
* enhancement: always lose() when something goes wrong while saving a core
(instead of just printing an error on stderr in some situations).
* enhancement: frames in the debugger are now restartable by default.
* bug fix: restore error handling on Windows x86.
* bug fix: MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
at compile-time when possible. (lp#330299)
* bug fix: parsing of malformed type specifiers no longer results
in a memory-fault-error.
* bug fix: LOOP properly destructures nested lists in WITH.
* bug fix: MACROEXPANDing the redefinition of an alien structure type no
longer signals the wrong error.
* bug fix: PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).
changes in sbcl-1.2.6 relative to sbcl-1.2.5:
* enhancement: SERVE-EVENTS uses the poll() system call in lieu of
select() if the OS has the former. Previously poll() was used
only if waiting on exactly one file descriptor.
* enhancement: efficiency of access to untagged structure slots is improved
on x86-64, and the order of slots in memory is exactly as specified by
defstruct, simplifying use of structures as arguments to foreign calls.
* bug fix: SB-DEBUG:ARG now works in all TRACE options which evaluate forms.
(lp#1357826)
* bug fix: GC memory corruption during internal memory handling.
* bug fix: duplicate effective-slot-definition objects as compared
by EQ on name could be present in CLASS-SLOTS of a class whose
metaclass was structure-class or condition-class. (lp#1049423)
* bug fix: HANDLER-BIND with empty bindings works again; regression in
1.2.5. (lp#1388707)
* bug fix: ATOMIC-INCF works on structure slots in interpreted code.
(lp#1381867)
* bug fix: MAKE-ARRAY properly handles character types like (eql #\a) and
(member #\a #\c). (lp#1392068)
* bug fix: READ sometimes accidentally preserved a whitespace character
after a token when it should not have. (lp#327790)
changes in sbcl-1.2.5 relative to sbcl-1.2.4:
* enhancement: sb-bsd-sockets now has basic support for IPv6
* enhancement: An sb-unicode package has been added, containing
many functions related to handling Unicode text
* enhancement: The reader now normalizes symbols to Normalization
Form KC (NFKC). This behavior can be disabled with
SB-EXT:READTABLE-NORMALIZATION
* enhancement: a style-warning is signaled if OPTIMIZE declarations
multiply specify a quality with differing values. (lp#310267)
* bug fix: conservatively pointed to pages wipe out unused dwords so
that they cannot act as false roots in turn.
* bug fix: the walker's handling of lexical variable and symbol-macro
bindings is improved (lp#375326, lp#1368305)
* bug fix: HANDLER-{BIND,CASE} no longer drop into ldb when a clause
contains an undefined condition type; regression in 1.1.19 (lp#1378939)
* bug fix: in interpreted code, inequality predicates did not type-check
arguments that weren't examined, and a 1-argument use of MIN or MAX
accepted a complex number. (lp#1373702)
* bug fix: APROPOS and APROPOS-LIST handle inherited symbols correctly.
(lp#1364413, thanks to Zach Beane)
changes in sbcl-1.2.4 relative to sbcl-1.2.3:
* enhancement: the sequence functions MAP, CONCATENATE and MERGE now call
the new generic functions SEQUENCE:MAP, SEQUENCE:CONCATENATE and
SEQUENCE:MERGE respectively when the specified result type designates an
extended sequence.
* bug fix: Wrong binding order of supplied-p parameters in macro lambda
lists. (lp#721135)
* bug fix: VALIDATE-SUPERCLASS returns T when the superclass is the
universal superclass (lp#1332983)
* bug fix: reading an uninterned symbol whose print name has the
syntax of an integer signals an error. (lp#310062)
* bug fix: the walker is less likely to be confused when walking LET* forms
with special bindings and use of those bindings and others of the same
name.
* bug fix: a rare bug affecting 32-bit platforms resulting in a
fatal condition with the message "Globaldb rehash failure" has been fixed.
changes in sbcl-1.2.3 relative to sbcl-1.2.2:
* enhancement: DOCUMENTATION works on instances of
FUNCALLABLE-STANDARD-CLASS
* enhancement: ASSERT reports arguments of calls to lexical functions in
additional to global functions.
* enhancement: ASDF updated to 3.1.3
* enhancement: UIOP can be loaded without ASDF.
* bug fix: some methods on CHANGE-CLASS did not finalize the new class
before accessing its class-precedence list.
* bug fix: CHANGE-CLASS no longer fails on unbound slots in the source
object.
* bug fix: CHANGE-CLASS signals an appropriate error when the destination
class is a FORWARD-REFERENCED-CLASS.
* bug fix: CHANGE-CLASS no longer signals bogus TYPE-ERRORs for slots for
which initargs have been supplied.
* bug fix: saving cores on ARM was broken since the introduction of GENCGC.
(lp#1349795)
* bug fix: macroexpanding a backquoted expression involving ",."
outside of the compiler failed. (lp#1354623)
changes in sbcl-1.2.2 relative to sbcl-1.2.1:
* incompatible change: the #\` ("backquote") reader macro was reimplemented
to support robust pretty-printing. Reading a form involving #\` produces
an invocation of the QUASIQUOTE ordinary macro which may contain subforms
that are not lists. Code that unportably attempts operations on
un-evaluated forms resulting therefrom, e.g.
(SUBST a b (read-from-string "`(x (,y))"))
might generate incorrect results and/or errors.
* enhancement: support for GNU/kFreeBSD x86.
* enhancement: ATOMIC-INCF and ATOMIC-DECF can operate on (CAR x), (CDR x)
and DEFGLOBAL variables of type fixnum.
* enhancement: arithmetic constant reduction is now performed on defconstant
constants too. (lp#1337069).
* bug fix: certain ftype proclamations containing &optional t &rest t no
longer cause subsequent definitions to signal bogus style-warnings.
* bug fix: #\Bell and #\Bel now read to different characters. (lp#1319452).
* bug fix: CAS SYMBOL-VALUE on locally special variables didn't work.
(lp#1098355)
changes in sbcl-1.2.1 relative to sbcl-1.2.0:
* enhancement: GENCGC is enabled on ARM.
* enhancement: better error reporting for invalid calls to local functions.
* enhancement: support for GNU/kFreeBSD distributions. (lp#1079954, thanks
to Christoph Egger)
* enhancement: experimental support for threads on NetBSD/x86-64. (thanks
to Robert Swindells)
* enhancement: support for DragonFly BSD. (lp#1292845, thanks to Vasily
Postnicov)
* bug fix: TYPE-OF must not return AND/OR/NOT expressions.
(lp#1317308)
* bug fix: accessing NIL arrays stopped producing errors. (lp#1311421)
* bug fix: DISASSEMBLE no longer prints unwanted stuff. (lp#1251861)
* bug fix: compiling SVREF on unknown types no longer produces scary errors.
(lp#1258716)
* bug fix: assorted LOOP fixes and enhancements. (lp#645534, lp#1322923,
lp#700538, lp#613876, lp#695286, lp#798388)
* bug fix: silence compiler notes from the SEARCH transform. (lp#1071310)
* bug fix: array type intersection handles T and unknown element types
correctly. (lp#1258716)
* bug fix: fix a corner case in array type unparsing that would result in
misleading translations from our internal type representation.
* bug fix: array-rank now sees through union and intersection types.
(lp#1310574)
* bug fix: when DECLARE expressions are in the wrong place, be careful not
to attempt to evaluate the subforms. (lp#573747; thanks to Roman
Marynchak)
* bug fix: misplaced and missing declarations in DEFTRANSFORM. (lp#1066451)
* bug fix: FBOUNDP returned NIL for a class of incorrect function names
instead of signaling an error. (lp#1095483)
* bug fix: fix a compile-time AVER in regalloc: lifetime analysis
used to (rarely) introduce duplicate conflict markers in a single
TN/block pair. (lp#1327008)
changes in sbcl-1.2.0 relative to sbcl-1.1.18:
* bug fix: read-time-eval backquote context mixup. (lp#1321047)
* enhancement: when SAVE-LISP-AND-DIE fails due multiple threads, the
report of the signaled conditions lists currently running threads.
* enhancement: ported to ARM linux.
* enhancement: sb-gmp contrib has been updated. (lp#1305266)
* enhancement: new contrib sb-mpfr by Stephan Frank.
* bug fix: MAKE-SEQUENCE works with sequence types defined via DEFTYPE
(lp#1315846, thanks to Mark Cox)
* bug fix: SET-[DISPATCH-]MACRO-CHARACTER should coerce a symbolic
function-designator to a function only as needed. (lp#1012335)
* bug fix: remove references to asdf-install from the manual. (lp#1207544,
thanks to Thomas Hlavaty)
* bug fix: handle --without-xxx options to make.sh more carefully.
(lp#1246665, thanks to Richard M Kreuter)
* bug fix: prevent maybe-delete-exit from doing semantically broken things
with local exits. (lp#309099, lp#518099, lp#533930)
* bug fix: attempts to subclass BUILT-IN-CLASSes signal errors, as required
by AMOP. (lp#861004)
changes in sbcl-1.1.14 relative to sbcl-1.1.13:
* optimization: complicated TYPEP tests are less opaque to the type
propagation pass. (lp#1229340)
* optimization: [N]BUTLAST perform a single pass over the list. (lp#1245697)
* optimization: EQUALP on structures with raw slots (double-float/complex)
no longer conses and is faster.
* optimization: RESTART-CASE expands to more compact code.
Thanks to Jan Moringen. (lp#1249055)
* enhancement: Top-level defmethod without defgeneric no longer causes
undefined-function warnings in subsequent forms. (lp#503095)
* enhancement: Better error messages for system errors on Windows.
* enhancement: run-sbcl.sh is usefully handled by rlwrap. Thanks to William
Cushing. (lp#1249183)
* enhancement: new function SB-EXT:ASSERT-VERSION->= accepts a version
specification (multiple integer arguments) and signals a continuable error
if the current SBCL version is lower (older) than the specification.
(lp#674372)
* enhancement: better ARRAY-RANK result derivation. (lp#1252108)
* bug fix: EQUALP now compares correctly structures with raw slots larger
than a single word.
* bug fix: contribs couldn't be built on Windows with MinGW.
* bug fix: Better pathname handling on Windows. (lp#922117)
* bug fix: OPEN reports a more meaningful error when an existing file is
opened for output with :if-exists :new-version. Thanks to Philip
Munksgaard. (lp#455381)
* bug fix: DEFSTRUCTs with NIL as a slot name no longer cause strange
CLOS-related errors. (lp#633911)
* bug fix: GC deadlocks caused by concurrent consing on Windows.
changes in sbcl-1.1.13 relative to sbcl-1.1.12:
* optimization: better distribution of SXHASH over small conses of related
values. (lp#309443)

** use the whole of the positive-fixnum range for SXHASH of fixnums
* enhancement: The error message when calling an undefined alien function
includes the name of the function on x86-64.

* enhancement: FIND-RESTART and COMPUTE-RESTARTS handle huge restart
clusters better in some cases
* enhancement: SOME/ANY/other quantification higher-order functions no
longer cons. (lp#1070635)
* bug fix: forward references to classes in fasls can now be loaded.
(lp#746132)
* bug fix: don't warn on a interpreted->compiled function redefinition
from the same location. (patch by Douglas Katzman, lp#1042405)

Windows. (lp#1239242)
* bug fix: function-lambda-expression on generic functions returns the
actual name.
* bug fix: (the [type] [constant]) now warns when [constant] matches
[type] except for the number of values. (Reported by Nathan Trapuzzano

is associated to a different condition (lp#774410)
changes in sbcl-1.1.12 relative to sbcl-1.1.11:
* enhancement: Add sb-bsd-sockets:socket-shutdown, for calling
shutdown(3). (thanks to Jan Moringen, lp#1207483)

/proc/pid/fd on Linux. (reported by Eric Schulte)
* bug fix: SBCL can now be built on Solaris x86-64.
* bug fix: Floating point exceptions do not persist on Solaris anymore.
* bug fix: (setf . a) is pprinted correctly (reported by Douglas Katzman).
* bug fix: handle compiler-error in LOAD when it's not run from inside EVAL.
(lp#1219601)
* bug fix: SB-GMP:MPZ-POW no longer segfaults given a non-bignum base.
(thanks to Stephan Frank)
* bug fix: space allocation of result bignums in SB-GMP is more accurate.
(thanks to Stephan Frank, lp#1206191)
* bug fix: sb-safepoint can now reliably handle signal interruptions of
foreign code. (lp#1133018)
* bug fix: the compiler-macro for MAKE-INSTANCE when emitting "fallback"
constructors no longer fails to merge actual and default initargs
(thanks to Jan Moringen, lp#1179858)
* bug fix: the compiler-macro for MAKE-INSTANCE when emitting "fallback"
constructors handles non-KEYWORD initialization arguments more correctly.
* bug fix: loading the SB-SIMPLE-STREAMS contributed module no longer
clobbers FILE-NAMESTRING. (thanks to Anton Kovalenko, lp#884603)
* bug fix: class definitions with CPLs inconsistent with their metaclasses
are less likely to destroy the object system's integrity. (lp#309076)
* bug fix: restart clause parsing in RESTART-CASE is more in line with the
standard. (lp#1203585, thanks to Jan Moringen)
* bug fix: silence a note from RESTART-CASE under high-SPEED optimization
settings. (lp#1023721)
* bug fix: getting the order of arguments to
SB-MOP:SET-FUNCALLABLE-INSTANCE-FUNCTION wrong produces a sensible error
rather than a failed AVER. (reported by Paul Nathan)
* bug fix: Parsing of &optional/&key/&rest arguments now never overwrites
arguments during copying on x86 and x86-64; it may still happen on other
platforms when there are more fixed arguments than stack slots.
(reported by Jan Moringen)
Note that contrary to last month's message, the increased type
opacity in the compiler has not been fixed in this release cycle.
changes in sbcl-1.1.11 relative to sbcl-1.1.10:
* enhancement: support building the manual under texinfo version 5.
(lp#1189146)
* enhancement: Windows builds no longer display the "Kitten of Death" message.
A warning is instead appended to the regular banner, and may be muted with
--noinform. (lp#728247)
* enhancement: support building under new linker handling of syscalls under
NetBSD. (thanks to Robert Swindells)
* bug fix: undefined function errors are now properly reported on PPC and MIPS.
(regression since 1.1.9)

* bug fix: improved threading on PPC.
* bug fix: ROOM works again on Windows. (lp#1206456)
* bug fix: Streams were flushed even when there was one byte still left in
the buffer. (lp#910213)
* bug fix: OPEN handles correctly when :if-exists and :if-does-not-exist are
either NIL or :ERROR. (reported by Jan Moringen)
As well as the release notes, appended below, it is worth noting
that some internal changes related to the optimization of type
tests for bounded positive integers might cause performance
regressions in code that dispatches based on the type of objects,
as in for example
(typecase x
((unsigned-byte 24) ...[1])
(t ...))
where in the region of code marked ...[1] the compiler could be expected
to infer that x was of type (unsigned-byte 24), but currently fails to
do so. This can be worked around by inserting an explicit declaration,
and the developers hope to address this in the next release cycle.
changes in sbcl-1.1.10 relative to sbcl-1.1.9:
* enhancement: ASDF has been updated to 3.0.2.
* optimization: stack frames are packed more efficiently on x86oids, which
ought to reduce the frequency of Methuselahn conservative references (it
certainly helps with gc.impure.lisp / BUG-936304 on x86).
* optimization: on x86 and x86-64, integer negation forms like (- x) are now
recognized in modular arithmetic contexts, and compile to native negate,
rather than going through bignums only to keep the low bits.
* bug fix: Compiling potential modularic arithmetic forms does not cause type
errors when some integer types lack lower or upper bounds. (lp#1199127)
* bug fix: Non-trivial modular arithmetic forms are always cut to the right
bitwidth before being used in a non-modular context. (lp#1199428)
* bug fix: Multiple catch/unwind blocks in a single function are now
allocated in the right stack order on win32. (lp#1072739)
changes in sbcl-1.1.9 relative to sbcl-1.1.8:
* new feature: the contrib SB-GMP links with libgmp at runtime to speed
up arithmetic on bignums and ratios. (contributed by Stephan Frank)
* enhancement: disassemble now annotates some previously missing static
functions, like LENGTH.

* enhancement: SB-EXT:PRINT-SYMBOL-WITH-PREFIX can be used within ~// to
print a symbol with a package prefix.
* enhancement: The debugger and backtracing are more robust against buggy
PRINT-OBJECT methods.
* optimization: calls to static functions on x86-64 use less instructions.
* optimization: compute encode-universal-time at compile time when possible.
* optimization: when referencing internal functions as #'x, don't go through
an indirect fdefn structure.
* optimization: SLEEP doesn't cons on non-immediate floats and on ratios.
* optimization: (mod fixnum) type-checks are performed using one unsigned
comparison, instead of two.
* optimization: enable more modular arithmetic transforms in the presence of
conditionals.
* optimization: bitwise OR forms can now trigger modular arithmetic as well,
when the result is known to be negative.
* optimization: recognize more cases of useless LOGAND/LOGIOR with constants.
* optimization: comparisons between rationals and constant floats or between
integers and constant ratios are now converted to rationals/integers at
compile time.
* optimization: Smaller and faster DOUBLE-FLOAT-LOW-BITS on x86-64.
* bug fix: problems with NCONC type derivation (reported by Jerry James).
* bug fix: EXPT type derivation no longer constructs bogus floating-point
types. (reported by Vsevolod Dyomkin)
* bug fix: sb-bsd-sockets has correct declaration of the canonname field of
addrinfo. (lp#1187041, patch by Jerry James)
* bug fix: uninitialized type-error conditions can now be printed.
(lp#1184586)
* bug fix: tests for sb-bsd-sockets no longer use a predefined port for
listening, allowing several tests to run in parallel.
* bug fix: during disassembly to *COMPILER-TRACE-OUTPUT* instruction
prefixes as used on x86 and x86-64 no longer sometimes print incorrectly.
(lp#1085729)
* bug fix: Specialised SIMD-PACK types can be negated.
* bug fix: Modular arithmetic is more robust. (incidentally fixes another bug
reported by Eric Marsden)
* bug fix: FP return values from foreign calls are always rounded to single
or double float precision on x87.
* bug fix: Known-safe vector access on x86oids should not fail spuriously
when the index is of the form (+ x constant-positive-integer).
* bug fix: Remove GPL-licensed files from source distribution. (lp#1185668)
* bug fix: backtrace printer no longer tries to create very large lists when
the arg-count register is clobberred by other code. (lp#1192929)
* bug fix: x86 should never signal an FP exception while boxing an FP value,
a situation that lands us into ldb.
changes in sbcl-1.1.2 relative to sbcl-1.1.1:
* notice: System requirements for SBCL on Microsoft Windows: Windows NT 5.1
or newer (Windows XP, Server 2003) is required. Support for Windows 2000
(NT 5.0) is no longer being maintained.
* notice: Starting with this version, SBCL on Windows no longer supports
building with disabled thread support.
* enhancement: frlocks have been added to SB-CONCURRENCY contrib module.

rebuilt or relocated without requiring changes to the core file on
all linkage table platforms. Required on Windows. (Thanks to Anton
Kovalenko.)
* enhancement: Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.)
* enhancement: I/O on Windows unnamed pipes is interruptible
asynchronously using interrupt-thread, timers when running on Windows NT
version 6.1 or newer (Windows 7, Server 2008 R2). (Thanks to Anton
Kovalenko.)
* enhancement: Support for the experimental safepoint-based stop-the-world
protocol on the PowerPC platform.
* bug fix: Non-blocking reads from the Windows console were not necessarily
non-blocking. Thanks to Anton Kovalenko. (lp#308923)
* bug fix: stability of threads on Windows has been improved upon through
an updated stop-the-world protocol (thanks to Anton Kovalenko).
New in version 1.0.55
* enhancements to building SBCL using make.sh:
+ --fancy can be specified to enable all supported feature
enhancements.
+ --with-<feature> and --without-<feature> can be used to
specify which features to build with.
+ --arch option can be used to specify the architecture to
build for. (Mainly useful for building 32-bit SBCL's on
x86-64 hosts, not full-blows cross-compilation.)
* enhancement: extended package prefix syntax
<pkgname>::<form-in-package> which allows specifying name
of the default interning package for the whole form.
* enhancement: when *READ-EVAL* is true, arrays with element
type other than T can be printed readably using #.-based
syntax. (Thanks to Robert Brown)
* enhancement: MAKE-ALIEN signals a storage-condition instead
of returning a null alien when malloc() fails. (#891268)
* enhancement: SB-EXT:PRINT-UNREADABLY restart for
PRINT-NOT-READABLE conditions can be conveniently accessed
through function with the same name, analogously to CONTINUE.
* enhancement: SB-EXT:*SUPPRESS-PRINT-ERRORS* can be used to
suppress errors from the printer by type, causing an error
marker to be printed instead. (Thanks to Attila Lendvai)
* enhancement: BACKTRACE and DESCRIBE now bind *PRINT-CIRCLE*
to T, and generally behave better when errors occur during
printing.
* enhancement: the test runner now takes a --report-skipped-tests
argument to report the individual tests skipped as well as the
number of skipped tests.
* enhancement: undefined functions now appear in backtraces as
("undefined function") instead of ("bogus stack frame") on
x86oids.
* enhancement: detected deadlocks no longer cause stderr to be
spammed, and deadlock errors are reported in an easier-to-decipher
manner.
* enhancement: DESCRIBE on type designators reports the
expansion in more cases.
* enhancement: SBCL now provides either an explicit :BIG-ENDIAN
or :LITTLE-ENDIAN in *FEATURES*, instead of :BIG-ENDIAN being
implied by lack of the :LITTLE-ENDIAN feature. (Thanks to
Luis Oliveira, #901661)
* enhancement: better disassembly of segment-prefixes on x86
and other instruction prefixes (e.g. LOCK) on x86 and x86-64.
* optimization: FIND and POSITION on bit-vectors are orders of
magnitude faster (assuming KEY and TEST are not used, or are
sufficiently trivial.)
* optimization: SUBSEQ on vectors of unknown element type is
substantially faster. (#902537)
* optimization: specialized arrays with non-zero :INITIAL-ELEMENT
can be stack-allocated. (#902351)
* optimization: the compiler is smarter about representation
selection for floating point constants used in full calls.
* optimization: the compiler no longer refuses to coerce large
fixnums to single floats inline, except on x86 where this
limitation is still necessary.
* bug fix: deadlock detection could report the same deadlock
twice, for two different threads. Now a single deadlock is
reported exactly once.
* bug fix: interval-arithmetic division during type derivation
did not account for signed zeros.
* bug fix: compiler error when typechecking a call to a
function with non-constant keyword arguments.
* bug fix: misoptimization of TRUNCATE causing erratic behaviour.
* bug fix: condition slot accessors no longer cause undefined
function style-warnings when used in the :REPORT clause of
the DEFINE-CONDITION form that defines them. (#896379)
* bug fix: DEFGENERIC warns about unsupported declarations, as
specified by ANSI. (#894202)
* bug fix: SUBTYPEP tests involving forward-referenced classes
no longer bogusly report NIL, T.
* bug fix: bogus style-warnings for DEFMETHOD forms that both
declared some required arguments ignored and performed
assignments to others. (#898331)
* bug fix: *EVALUATOR-MODE* :COMPILE treated (LET () ...)
identically to (LOCALLY ...) leading to internally
inconsistent toplevel-formness.
* bug fix: non-toplevel DEFSTRUCT signaled a style warning for
unknown type.
* bug fix: redefining a function whose previous definition
contained an unknown type no longer causes a style-warning. (#806243)
* bug fix: undefined functions now appear in backtraces as
("undefined function") instead of ("bogus stack frame") on non-x86oids.
* bug fix: backtraces are no longer cut off at ("undefined
function") when called under certain circumstances (involving a
caller-allocated stack frame) on PPC.
* bug fix: RUN-PROGRAM leaked a file-descriptor per call on
non-Windows systems. (regression since 1.0.53)
* bug fix: GC deadlocks from dladdr() on certain platforms.
* bug fix: broken standard streams no longer automatically
cause recursive errors on debugger entry.
* bug fix: build ignored --dynamic-space-size=<size> argument
to make.sh (regression since 1.0.53)

function with an external entry point caused compiler-errors.
* bug fix: compiler notes for failed stack allocation for a
function argument no longer claim to be unable to stack
allocate the function.
* bug fix: COERCE now signals a type-error on several
coercions to subtypes of CHARACTER that are forbidden
according to ANSI. (#841312)
* bug fix: missing failure-to-stack-allocate compiler notes
for some forms of MAKE-ARRAY with dynamic-extent. (#902351)
* bug fix: some of the compile-time side-effects of DEFCLASS
were not caught by package locks.
changes in sbcl-1.0.54 relative to sbcl-1.0.53:
* minor incompatible changes:
** RENAME-FILE on a symbolic links used to rename the linked-to file
instead of the link.
** DELETE-DIRECTORY on symbolic link to a directory used to delete the
directory, but now signal an error instead. Use TRUENAME to resolve the
pathname if you wish to delete the linked directory, and DELETE-FILE if
you wish to delete the
** The internal SB-THREAD::SPINLOCK API has been deprecated, and using
symbols associated with it will trigger a compile-time warning.
* thread-related enhancements:
(This work has been funded by the SBCL Threading 2011 IndieGoGo campaign.
Many thanks to generous donors!)
** Threading is now more reliable on non-Linux platforms. We still don't
consider threads on non-Linux platforms good enough to enable them by
default, but they're in a clearly better shape now.
** Deadlines supported now on all platforms.
** All blocking functions in the threading API now have a :TIMEOUT
argument.
** Semaphore notification objects have been added to SB-THREAD.
** SB-CONCURRENCY contrib now includes Allegro-style GATE objects.
** SB-EXT:COMPARE-AND-SWAP has been extended to support SLOT-VALUE,
STANDARD-INSTANCE-ACCESS, and FUNCALLABLE-STANDARD-INSTANCE-ACCESS.
** Users can now defined new places usable with SB-EXT:COMPARE-AND-SWAP
using an API anologous to defining new SETFable places.
* GC-related enhancements and bug fixes:
** --dynamic-space-size and --control-stack-size now understand Kb, Mb,
and Gb suffixes. Default is megabytes as before.
** on GENCGC targets, the default dynamic space size is now 512Mb for
32-bit systems, and 1Gb for 64-bit systems. (OpenBSD/x86-64 is the only
exception, defaulting to mere 444Mb to fit under default ulimits.) The
new defaults are in place to prevent hitting swap on low-end systems.
Use build-time option --dynamic-space-size to build an SBCL with
another default, or the runtime option to adjust the size at startup: a
good size is at most equal to the amount of physical memory the system
has.
** on GENCGC targets, nursery and generation sizes now default to 5% of
dynamic-space size.
** on GENCGC targets, SB-KERNEL:MAKE-LISP-OBJ no longer categorically
refuses to create SIMPLE-FUN objects.
** on 64-bit GENCGC targets, setting the nursery size above 4Gb now works.
(lp#870868)
** on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does the same
validation of pointer objects as GENCGC does, instead of a
comparatively weak bounds-check against the heap spaces.
* SB-BSD-SOCKETS bug fixes:
** GET-PROTOCOL-BY-NAME had a significant memory leak.
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS small amounts of memory on
systems with getaddrinfo().
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS weren't thread or interrupt
safe outside systems with getaddrinfo().
* enhancement: ASDF has been updated 2.019.
* enhancement: special-case TCO prevention for functions which never return
extended to untrusted types, keeping one more frame's worth of debug
information around in many cases.
* enhancement: debug-names of anonymous and local function are more
descriptive. Affects backtraces and SB-SPROF results. (lp#805100)
* enhancement: on win32, ABS of complex floats guards better against
overflows. (lp#888410)
* enhancement: RUN-PROGRAM now distinguishes exec() failing from child
process exiting with code 1. (lp#676987)
* enhancement: convenience function SET-SBCL-SOURCE-LOCATION for informing
the system where on the filesystem the SBCL sources themselves are
located. (Thanks to Zach Beane)
* enhancement: the compiler is now able to derive tighter bounds for
floating point numbers in some cases. (Thanks to Lutz Euler, lp#894498)
* bug fix: on 64-bit targets, atomic-incf/aref does index computation
correctly, even on wide-fixnum builds. (lp#887220)
* bug fix: (DIRECTORY "foo/*/*.*") did not follow symlinks in foo/ that
resolved to directories.
* bug fix: type mismatch when assigning to lexical variables no longer
result in fasl-dumping internal type objects. (lp#890750)
* bug fix: type mismatch on (SETF AREF) and function return values no
longer result in fasl-dumping internal type objects.
* bug fix: With several combinations of argument types, for example (EXPT
<integer> <(complex double)>), EXPT now uses double-precision throughout
instead of partially calculating only to single-precision. (lp#741564;
thanks to Lutz Euler)
* bug fix: SYMBOL-VALUE-IN-THREAD is no longer able to construct bogus
objects when interrupted by GC on PPC.
changes in sbcl-1.0.49 relative to sbcl-1.0.48:
* minor incompatible change: WITH-LOCKED-HASH-TABLE no longer disables
interrupts for its body.
* enhancement: source locations are now available for files loaded as
source, compile-time-too evaluation, and initialization files.
* enhancement: WITH-COMPILATION-UNIT :SOURCE-NAMESTRING allows providing
virtual source-file information, eg. overriding input-file of COMPILE-FILE
when a temporary file is used for compilation.
* enhancement: ASDF has been updated to version 2.015.3.
* enhancement: backtraces involving frames from the default evaluator are
more readable.
* enhancement: RUN-PROGRAM works with user-defined binary input and output
streams.
* enhancement: more informative compile-time warnings and runtime errors for
type-errors detected at compile-time.
* enhancement: deadlock detection for mutexes and spinlocks.
* enhancement: dynamic-extent for &rest lists stack allocate only their
spines, not their argumets. While portable code should not rely on this,
particularly in combination with inlining, it should make dynamic-extent
easier to use safely.
* enhancement: SB-POSIX improvements:
** WNOHANG and WUNTRACED are exported.
** SYSCALL-ERROR now also provides the name of the failing system call.
* enhancement: --script improvements:
** errors on standard input, output, and error streams are handled and
cause scripts to exit silently, making them easier to use in shell
pipelines.
** backtraces from scripts now go to standard error instead of the
terminal even if one is available.
** --script can be an argument, causing the script to be loaded from
standard input.
* enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp
strings to foreign memory.
* enhancement: (SETF GC-LOGFILE) allows logging garbage collections to
a file, making it easier to understand heap dynamics.
* optimization: using a &REST argument only in APPLY or VALUES-LIST calls
allows the compiler to automatically elide rest-list allocation so long as
the call sites are in functions that the compiler knows cannot escape.
(lp#504575)
* optimization: CALL-NEXT-METHOD using explicit arguments is faster,
especially in safe code when none of the required arguments have changed
their identities.
* bug fix: blocking reads from FIFOs created by RUN-PROGRAM were
uninterruptible, as well as blocking reads from socket streams created
with for which :SERVE-EVENTS NIL. (regression from 1.0.42.43)
* bug fix: SET-SYNTAX-FROM-CHAR now removes dispatch-macro character syntax
from the to-char if the from-char is not a dispatch-macro character.
* bug fix: references to undefined variables in function calls that are
optimized away now signal a runtime error. (lp#722734)
* bug fix: miscompilation of MULTIPLE-VALUE-CALL when asserting derived
types from a function defined in the same file. (regression from
1.0.43.57)
* bug fix: TRULY-THE forms are now macroexpandable and setf-expandable.
(lp#771673)
* bug fix: spurious errors during QUIT when standard streams were closed.
New in version 1.0.45
* enhancement: ~/ and ~user/ are treated specially in pathnames.
* enhancement: ASDF has been updated to version 2.010.
* optimization: mutated closed-over variables that are only accessed
by DYNAMIC-EXTENT closures (currently only FLET and LABELS functions
declared to be DYNAMIC-EXTENT) are stored directly in their containing
stack frame, rather than allocating a VALUE-CELL (#586103).
* optimization: UNWIND-PROTECT cleanup functions are now declared
DYNAMIC-EXTENT.
Bug fixes.
New in version 1.0.44
* enhancement: RUN-PROGRAM accepts :EXTERNAL-FORMAT argument
to select the external-format for its :INPUT, :OUTPUT, AND
:ERROR :STREAMs.
* enhancement: ALLOCATION-INFORMATION also provides the page
the object resides on.
* enhancement: default dynamic-space size can be configured at
build-time without touching source, using the --dynamic-space-size
argument to make.sh.
* enhancement: DESCRIBE recognizes symbols naming optimization
policy qualities, and mentions ALWAYS-BOUND declarations.
* enhancement: ATOMIC-INCF now supports AREF of
(SIMPLE-ARRAY SB-EXT:WORD (*)) as a place.
* enhancement: ASDF has been updated to 2.009.
* enhancement: the system detects known type-erros in calls better,
signalling a full warning about violated proclaimed FTYPEs and
violations of derived FTYPEs within the same file, including self-calls.
* enhancement: new function: SB-EXT:DELETE-DIRECTORY is now provided.
* optimization: constant-folding exploits numeric and character types,
in addition member types.
* optimization: numeric, character and member types that are inhabited
by exactly one value are tested with EQL.
* optimization: more conditional branches are eliminated during IR1.
Branches are simplified before performing if/if-conversion,
and simple equivalent branches (that only read the same constant
or variable) are merged.
* improvements to the Windows port:
+ change: canonical unparsing form for pathname namestrings now
uses / as directory separator. NATIVE-NAMESTRING still uses \
as the separator.
+ bug fix: stackoverwriting due to incorrect usage of PeekConsoleInput
on Windows. (thanks to Kalyanov Dmitry)
+ bug fix: build now works on cygwin with GCC 4.x installed.
+ bug fix: run-sbcl.sh now works on Cygwin. (thanks to Kalyanov Dmitry)
Bug fixes.
New in version 1.0.43
* incompatible change: FD-STREAMS no longer participate in the
serve-event event-loop by default. (#316072)
+ In addition to streams created by explicit calls to MAKE-FD-STREAM
this affects streams from CL:OPEN.
+ Streams from SOCKET-MAKE-STREAM still participate in
serve-event by default, but this is liable to change:
applications needing serve-event for socket streams
should explicitly request it using :SERVE-EVENTS T in the call.
* enhancement: SB-EXT:WORD type is provided for use with
SB-EXT:ATOMIC-INCF &co.
* enhancement: CLOS effective method functions and defclass slot
typechecking function now have debug names for use in backtraces
and profiles.
* enhancement: ASDF has been updated to version 2.004.
* enhancement: symbols are printed using fully qualified names
in several error and warning messages which are often associated
with package conflicts or mixups (#622789, thanks to Attila Lendvai)
Bug fixes.
New in version 1.0.39
- bug fix: Backtrace from undefined function on x86 and x86-64
now show the calling frame.
- bug fix: linkage-table entries on PPC now no longer overflow
their space allocation (potentially causing crashes if they
are written out of order).
- bug fix: Scrub control stack after scavenging in gencgc on
non-x86oid platforms, preventing the GC from seeing stale
pointers on the control stack in subsequent GCs (which would,
and does, break invariants).
- bug fix: 32-bit unicode external formats now work on big-endian systems.
- bug fix: Literal characters with code points greater than
about 32767 now work on PPC UNICODE builds.
- bug fix: Any noise left by SSE operations (sqrt and
conversions) in the high order bits are explicitly cleared
out. In some contrived situations, this could lead to wrong
results in mixed real/complex float arithmetic.
- bug fix: Fix function/macro redefinition warnings when
building with clisp. (#576787, thanks to Josh Elsasser)
- new platform: experimental support for ppc/openbsd (thanks to
Josh Elsasser).
- bug fix: Floating-point traps now work on ppc/linux.
changes in sbcl-1.0.38 relative to sbcl-1.0.37:
* incompatible change: Thread names are now restricted to SIMPLE-STRINGs
like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
* deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
* deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
SB-THREAD:GRAB-MUTEX.
* new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
contain additional data structures and tools for concurrent programming;
at the moment it contains a lock-free queue, and a lock-free mailbox
implementation.
* new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
GET-MUTEX but takes &key rather than &optional parameters. Also added
:TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
BSD.
* new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
SB-THREAD:WAIT-ON-SEMAPHORE.
* new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
SB-EXT:ATOMIC-INCF.

now bivalent.
* enhancement: errors from NO-APPLICABLE-METHOD and
NO-PRIMARY-METHOD now have a RETRY restart available to retry the
generic function call.
* enhancement: SB-BSD-SOCKET improvements
** sockets and socket streams now have a more informative printed
representation based on the corresponding SOCKET-NAME and
SOCKET-PEERNAME.
** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
(lp#540413)
** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
CL:CLOSE when appropriate, and no longer disassociates the stream
from the socket if close failed. (lp#543951)
* improvements to the instrumenting profiler
** new feature: report per-function GC overhead. (thanks to John Fremlin)
** optimization: counters no longer use locks for the overflow mode.
** bug fix: whenever a profiling counter wrapped into overflow mode, it
incurred an off-by-one miscount.
* enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
* enhancement: improved DEFMETHOD pretty-printing.
* enhancement: perform range reduction when arguments are too large for
x87's transcendentals (instead of returning 0). (lp#327192)
* enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
some of CL-PPCRE's macros. (lp#570079)
* enhancement: our machine code is slightly less hostile to valgrind on
x86-64.
* enhancement: up-to-date versions of NetBSD-current are supported. (Thanks
to Robert Swindells and Aleksej Saushev)
* bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
* bug fix: a rare case of startup-time page table corruption.
* bug fix: a semaphore with multiple waiters and some of them unwinding due
to timeouts could be left in an inconsistent state.

* bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
up itself" (March 2010) for further details.
* bug fix: allow forward FIND and POSITION on lists to elide checking :END
against length of the list if the element is found before the specified
END is reached. (thanks to Alec Berryman, lp#554385)
* bug fix: errors signalled during package graph modification no longer
block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
* bug fix: SB-POSIX build was broken when SBCL was compiled without the
:SB-DOC feature. (lp#552564)
* bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
* bug fix: more robust runtime executable path detection. (lp#375549)
* bug fix: GCD always returns positive values. (lp#413680)
* bug fix: Converting division to multiplication by reciprocal handles
denormals.
* bug fix: We were too eager in eliding range reduction tests on x87.
The maximal magnitude is 2^63, not 2^64.
* bug fix: Transforms for TRUNCATE don't die when the result is completely
ignored anymore.
* bug fix: Maybe restore buildability on Alpha.

types) could result in type mismatches during compilation.
changes in sbcl-1.0.37 relative to sbcl-1.0.36:
* enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
stack frame thrown from.
* enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to
compiler optimization qualities inside dynamic extent of its body.
* enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load
translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
Weber)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
constraint propgation, allowing better compilation eg. when used to
access structures with WITH-SLOTS. (lp#520366)
* optimization: the compiler is now more aware of the type of the underlying
storage vector for multidimensional simple arrays resulting in better code
for accessing such arrays.
* optimization: passing NIL as the environment argument to TYPEP no longer
inhibits optimizing it. (lp#309788)
* optimization: more efficient register usage when handling single-float
arguments on x86-64. (thanks to Lutz Euler)

New in version 1.0.36
- new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND
counterparts but work on type specifiers.
- new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a
symbol is known to name a type specifier.
- new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a
given type specifier is valid where "valid" basically means
"would be accepted as second argument of TYPEP".
- new feature: SB-INTROSPECT:FUNCTION-TYPE takes a
function-designator and returns the function's declared, or
derived FTYPE.
- new feature: SB-POSIX now supports accessing the d_ino
member of dirent structures. (Thanks to Philipp Marek and
Pierre THEIRRY)
- new feature: The function SB-EXT:SEED-RANDOM-STATE has been
added to provide for seeding a RANDOM-STATE object with
user-provided data or from the operating system's PRNG.
Also, (MAKE-RANDOM-STATE T) will attempt to initialize the
returned state from the operating system's PRNG where
possible. (Thanks to Fare Rideau; launchpad bug #310116)
- bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set
the FILE-POSITION of the stream being read from. (launchpad
bug #491087)
- bug fix: Fix grammar and style issues for the docstrings of
printer-related variables and functions. (Thanks to mon_key;
launchpad bug #518696)
- bug fix: Fix compilation on chenygc platforms. Thanks to
Larry Valkama and Bruce O'Neel.
- bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a
deadline twice in a row even though a handler defered the
deadline long into the future. (#512914)
- bug fix: A deadline handler was run without interrupts
enabled for a deadline signaled within
SB-THREAD:CONDITION-WAIT.
That could result in infinitely spinning, non-killable threads.
- bug fix: Backtrace from internal-errors on x86-64 os x was
truncated before reaching the erring stack frame.
- bug fix: Fix type derivation for EXPT when raising a fixnum
to a real power. (launchpad bug #525949)

- bug fix: More robust checks for invalid DEFMETHOD argument
specializers. (launchpad bug #525916)
- bug fix: Fix building on Darwin when sysctl is not in the
user's PATH. (Thanks to Robert Goldman)
Changes since previous packaged version are too long to list,
they include 1,5 years of continuous development, adding features,
compiler optimizations, and fixing bugs. See log at
http://www.sbcl.org/all-news.html
build the newer version. This should allow the package to be
included in bulk builds, and eliminate the troubles with other
Common Lisp systems being fragile WRT building this system.
Update to 1.0.16
New version has NetBSD/powerpc support (although I haven't adjusted
the Makefile due to lack of test machines) and now builds the
sb-posix package properly.
I would list the changes to the package here, but SBCL makes a new
release every month, and there are usually a dozen or more minor
changes per release. The previous version of this package is about
18 months old...
