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: (funcall (function X junk)) didn't causes an error when X had a
compiler macro. (thanks to Douglas Katzman).
* bug fix: signal a warning when defining a setf-function when a
setf-expander is already present. (thanks to Douglas Katzman).
* 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: clean.sh now also cleans doc/internals.
* 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-1.1.8 relative to sbcl-1.1.7:
* notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of
ROOM, plus a few SB-INTROSPECT functions) has been completely
rewritten; it may now exhibit different bugs than before.
* new feature: minimal runtime/compiler intrastructure support for SSE
SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64 via the build-time
feature :sb-simd-pack. This should enable intrinsics extensions as
libraries, without patching SBCL itself. Thanks to Alexander Gavrilov
for maintaining a branch for so long.
* enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
* enhancement: boxed vectors (vectors of T or of FIXNUM) can now be
stack-allocated on PPC.
* enhancement: "fixed objects" can now be stack-allocated on PPC.
* enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
* enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now
also returns VOPs which do not translate any functions, and finds
defoptimizer types ir2convert and stack-allocate-result.
* enhancement: better type derivation for APPEND, NCONC, LIST.
(lp#538957)
* enhancement: MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the
heap in a manner similar to the GC rather than its previous ad-hoc
scheme, and is therefore no less and possibly more accurate.
* fixes and enhancements related to Unicode:
** the character database information has been updated to Unicode 6.2;
** support for canonical and compatibility decomposition of characters has
been added, along with support for primary composition;
** support for Unicode normalization forms of strings (NFC, NFKC, NFD and
NFKD) has been included;
** querying the character database for code points not defined by Unicode
gives less wrong answers (lp#1178038, reported by Ken Harris)
* enhancement: print intermediate evaluation results for some ASSERTed
expressions. (lp#789497) (patch by Alexandra Barchunova)
* enhancement: x86-64 disassemblies are annotated with unboxed constant
values when there are references to (RIP-relative) unboxed constants.
* bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
of quadratically with the size of the input in the worst case.
(lp#1096444)
* bug fix: handle errors when initializing *default-pathname-defaults*,
sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like character
decoding errors, or directories being deleted.
* bug fix: Loading a core with a discontiguous dynamic space now correctly
computes the amount of dynamic space used.
* bug fix: disassembler missing ",8" on SHLD
* bug fix: backtracing through INTERNAL-ERROR signal handlers on systems
that provide an "invalid" stack frame link for the signal handler
itself now use the saved-fp-and-pc mechanism to pick up from the stack
frame in the interrupt (signal) context. This is known to affect
threaded FreeBSD/x86-64.
* bug fix: some LOOP statements couldn't be compiled.
(lp#1178989)
* bug fix: sb-sequence:dosequence works on literal vectors.
* bug fix: errors in generic arithmetic show the assembly routine's
caller on x86 and x86-64. (lp#800343)
* bug fix: Compile-time type errors should never result in COMPILE-FILE
failure. (lp#943953)
* bug fix: Known bad local calls do not cause strange failures when
emitting or dumping code. (lp#504121)
* bug fix: Multiply-inlined structure constructor don't cause IR2-time
codegen errors: type checks are inserted as necessary. (lp#1177703)
* bug fix: Unsigned modular arithmetic is correctly converted into signed
modular arithemtic (mostly to exploit fixnum-width VOPs). (lp#1026634)
* bug fix: a combination of inlined local function with &optional and
recursion no longer causes undescriptive compiler errors. (lp#1180992)
* bug fix: sub-word BOOLEAN alien types now disregard higher order bits
when testing for non-zero-ness.
* bug fix: (CONCATENATE 'null ...) no longer fails for generic sequences.
(lp#1162301)
* bug fix: Type mismatch for the value of conditional expressions are
correctly reported when detected at compile-time, instead of complaining
about a constant NIL (similar for non-EQ-comparable catch tags).
* bug fix: Referring to INLINE global functions as values should not result
in a compilation failure. (lp#1035721)
* optimization: faster ISQRT on fixnums and small bignums
* optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
* optimization: On x86-64, the number of multi-byte NOP instructions used
for code alignment is now always minimal.
* optimization: On 64-bit targets, the compiler generates much faster
code for type checks for types known at compile time that are smaller
than (SIGNED-BYTE 64) or (UNSIGNED-BYTE 64) and larger than FIXNUM, and
their COMPLEX variants.
* optimization: On x86 targets, more uses of ALIEN-FUNCALL during cross
compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance.
* optimization: ROOM no longer conses so egregiously on non-x86oid
systems.
* optimization: associative bitwise operations reassociate patterns like
(f (f x k1) k2) to expose (f x (f k1 k2)). Same for + and * of
rational values.
* optimization: quasiquote expressions now perform more constant folding,
instead of consing equal lists at runtime. (lp#1026439)
* optimization: local call analysis of inlined higher-order function
should converge more quickly, resulting in better code for complex
functions.
* optimization: On x86-64, medium (word-sized but wider than 32 bits)
integer constants are handled more cleverly, especially when they
can be represented as sign-extended (signed-byte 32). (Based on a
patch by Douglas Katzman)
* optimization: IF/IF conversion should reliably result in sane code
when (some of) the results of the inner IF are always false or
always true.
* optimization: On x86oids, variable right shifts of machine words are
compiled into straight SAR/SHR, instead of going through the generic
VOP. (lp#1066204)
changes in sbcl-1.1.7 relative to sbcl-1.1.6:
* enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
(lp#457053)
* bug fix: :allocation slot option works for condition slots
(lp#1049404)
* bug fix: redefining conditions does not lead to multiple evaluations of
hairy slot initfunctions anymore (lp#1164969)
* bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
(lp#1164970)
* bug fix: function constants now work as initforms and default initarg
values of conditions (lp#539517)
* bug fix: svref/(setf svref) on symbol macros don't crash the compiler
anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel)
* bug fix: no more bogus ## references when pretty printing backquoted
forms with non-trivial structure sharing. (lp#1161218)
* bug fix: Don't signal an error on (setf (documentation nil 'function)
"doc"). Signal a style-warning instead when trying to set documentation
of NIL for all other documentation types. (Reported by Zach
Beane; regression since 2e52fa05.)
* bug fix: modular arithmetic involving large constants and conditionals
should no longer result in spurious dead code elimination. (Reported by
Eric Marsden).
* bug fix: our mach exception handler can seemingly called very early in
the program execution process on OS X 10.8.0. Try and handle that case
robustly, without potentially leaking mach ports too much.
* optimization: LOGBITP and LOGTEST optimizations from x86 ported to x86_64.
changes in sbcl-1.1.6 relative to sbcl-1.1.5:
* enhancement: the continuable error when defknown-ing over extant
fndb entries can be ignored by passing :overwrite-fndb-silently t
as a keyword argument to sb-c:defknown (after attributes). Useful
to allow defknown to be re-loaded. Use with :allow-other-keys t
for backward compatibility.
* optimization: compiler is much faster in compiling SVREF and (SETF SVREF)
forms.
* bug fix: Prevent a make-array transform from modifying source forms
causing problems for inlined code. Thanks to Bart Botta.
(regression since 1.0.42.11-bis)
* bug fix: clear-output calls the correct gray stream routine,
sb-gray:stream-clear-output. (lp#1153257)
* bug fix: an error is signalled for an invalid format modifier: ~<~@>.
(lp#1153148)
* bug fix: Better error messages for package operations (lp#1154776)
* bug fix: delete-package on a nonexistent package should signal a cerror.
(regression since 1.0.37.44).
* bug fix: accessing &MORE (stack allocated &REST) arguments checks bounds.
(lp#1154946, lp#1072112)
* bug fix: compiling make-array no longer signals an error when the
element-type is an uknown type, a warning is issued instead.
Thanks to James Kalenius (lp#1156095)
* bug fix: SEARCH on generic (non-VECTOR non-LIST) sequence types no longer
produces wrong results for some inputs. (Thanks to Jan Moringen.)
(lp#1153312)
changes in sbcl-1.1.5 relative to sbcl-1.1.4:
* minor incompatible change: SB-SPROF:WITH-PROFILING no longer loops
by default.
* new feature: package local nicknames. See manual for details.
* new feature: SB-EXT:MAP-DIRECTORY provides a powerful interface for
directory traversal: it is the backend used by SBCL for CL:DIRECTORY.
* enhancement: easier to use restarts for resolving name-conflicts
resulting from IMPORT, EXPORT, or USE-PACKAGE.
* enhancement: variant DEFPACKAGE forms now signal a full error with
restarts provided for resolving the situation. (lp#891351)
* enhancement: by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant
DEFPACKAGE forms can now signal a full error with restarts provided for
resolving the situation. See manual for details. (lp#891351)
* enhancement: make-random-state now uses CryptGenRandom as a seed on Windows.
(Thanks to Anton Kovalenko.) (lp#1102748)
* enhancement: backtrace improvements
** secondary CLOS dispatch functions have better debug names (lp#503081)
** easier to read method names in backtraces. See
SB-DEBUG:*METHOD-FRAME-STYLE*.
** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are available as
forwards-compatible replacements for SB-DEBUG:BACKTRACE and
SB-DEBUG:BACKTRACE-AS-LIST.
** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as the same
information is available in less intrusive form as frame annotations.
* enhancement: SB-POSIX now provides MAP-ANON.
* enhancement: test-suite results are colorized, failures in red, unexpected
success in green. Works on Windows and on terminals with ANSI escape code
support. Can be disabled with --no-color.
* optimization: SB-CONCURRENCY:QUEUE implementation is more efficient.
(thanks to James M. Lawrence)
* bug fix: no more unused variable style warnings from RESTART-CASE
macroexpansion (lp#1113859)
* bug fix: no more unused variable style warnings when loading
sb-bsd-sockets.asd (lp#1114681)
* bug fix: deleting a package removes it from implementation-package
lists of other packages.
* bug fix: SB-SPROF:WITH-PROFILING is now usable in the Slime REPL on Darwin.
This does not fix the occasional "interrupt already pending" issue, though.
* bug fix: (setf (documentation 'x 'function)) and
(setf (documentation #'x t)) set documentation in different places.
(regression since 1.0.43.63)
* bug fix: build on newer glibc. (lp#1095036)
changes in sbcl-1.1.4 relative to sbcl-1.1.3:
* optimization: LOOP expressions using "of-type character" have slightly
more efficient expansions.
* bug fix: very long (or infinite) constant lists in DOLIST do not result
in very long compile times or heap exhaustion anymore. (lp#1095488)
* bug fix: `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918)
* bug fix: adjust-array ignored :initial-element for simple-vectors.
(lp#1096359)
* bug fix: optimizations to MAKE-INSTANCE with literal list initargs no
longer cause infinite loops (on circular data) or violate eqlity
constraints. (lp#1099708)
* bug fix: FIRST was not being open coded. (regression from 1.1.0)
changes in sbcl-1.1.3 relative to sbcl-1.1.2:
* enhancement: warnings about bad locale settings, LANG, LC_CTYPE, etc.
(lp#727625)
* enhancement: support for C-c to interrupt the foreground thread
on Windows. (Thanks to Anton Kovalenko.)

function invocation. On safepoint builds only.
* enhancement: Miscellaneous improvements to namestrings and underlying
calls to OS functions for file system access on Windows. (Thanks to
Anton Kovalenko.)
* enhancement: The MSI installer support for Windows now uses Windows
Installer XML at least version 3.5 and includes various usability

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.
* enhancement: New feature sb-dynamic-core allows the runtime to be
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).

changes in sbcl-1.1.1 relative to sbcl-1.1.0:
* enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
(COMPILE and COMPILE-FILE still do.)
* optimization: the SPARC backend now supports the precise generational
(GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
* enhancement: add experimental support for the SB-THREAD feature and the
timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
Threads are enabled by default, and this version of SBCL is considered
to be the last and final release to officially support building with
threads disabled.
* optimization: The compiler no longer rotates loops in some cases where
this transformation actually lead to worse code being generated.
* bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
symbol-macros by lexical bindings.
* bug fix: stack allocation was prevented by high DEBUG declaration in
several cases.

pkgsrc changes:
* "user-destdir" is default these days, remove setting.
Changes in sbcl-1.1.0 relative to sbcl-1.0.58:
* enhancement: New variable, sb-ext:*disassemble-annotate* for controlling
source annotation of DISASSEMBLE output. Defaults to T.
* enhancement: TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
WAIT-P argument added to WITH-RECURSIVE-LOCK.
* enhancement: SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations
on list heads.
* enhancement: Optional features (not enabled by default) allow the
use of signals for inter-thread synchronization to be reduced on certain
supported platforms (currently Linux, Solaris, and FreeBSD on x86 and
x86-64). Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer)
to test these experimental features. Known remaining bugs include minor
thread safety issues, less timely freeing of memory by GC, and certain
(not yet optimally low) runtime overhead. Thanks to Anton Kovalenko.
* optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
comparisons, particularly on almost-sorted inputs.
* bug fix: Reading floats with large exponents no longer takes too much time
before reporting that the exponent is too large.
* bug fix: SB-BSD-SOCKETS:SOCKET-RECEIVE with a UDP socket now works
correctly when the received datagram is larger than the provided buffer.
(lp#1023438, thanks to Robert Uhl)
* bug fix: SB-EXT:GET-CAS-EXPANSION returned a bogus read-form when given
a SYMBOL-VALUE form with a constant symbol argument.
* bug fix: SB-EXT:GET-CAS-EXPANSION signaled an error when a macro expanding
into a DEFCAS defined place was used as the place.
* bug fix: FIND and POSITION signaled a type-error when non-bits where looked
for from bit-vectors.
* bug fix: a race condition around thread creation could (in SBCL 1.0.57)
lead to internal errors or crashes (lp#1058799).
* documentation: a section on random number generation has been added to the
manual. (lp#656839)

Changes in sbcl-1.0.58 relative to sbcl-1.0.57:
* enhancement: implicit generic function warnings now specify the package
in which the new generic function is being created.
* enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform non-destructive
updates of CAS-able places (similar to Clojure's swap!).
* enhancement: run-program no longer decodes and re-encodes environment when
:environment argument is not provided. (lp#985904)
* enhancement: errors during compiler-macro expansion no longer cause
runtime errors, only a compile-time warning, otherwise behaving as if
the compiler macro had declined to expand.
* optimization: On x86-64, code alignment of block headers is done with
multi-byte NOPs now instead of repetitions of the single-byte NOP.
* optimization: MAP-INTO is substantially faster when the target sequence is
of unknown type; mapping into lists is no longer O(N^2). (thanks to James
M. Lawrence)
* optimization: the compiler no longer heap-conses to check exits in cases
where the exit function is dynamic extent, or when it can prove the exit
function cannot escape.
* optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
element type, and vectors that aren't SIMPLE-ARRAYs.
* optimization: CL:SORT and CL:STABLE-SORT are more efficient in execution
speed (around 1/3 the time in some cases), and a little better in terms of
comparison calls. (Thanks to Takeru Ohta)
* bug fix: On SPARC, a limitation on the number of code constants emittable
by the compiler has been lifted, allowing certain long functions to
compiled and assembled which had previously been unsupported; fixes
cl-bench on this ISA (lp#1008996).
* bug fix: potential for infinite recursion during compilation of CLOS slot
typechecks when dependency graph had loops. (lp#1001799)
* bug fix: error forms reported with some program-errors were not escaped
properly.
* bug fix: functions from EVAL are now on more equal footing with functions
from COMPILE. (lp#1000783, lp#851170, lp#922408)
* bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method combination
objects as its :METHOD-COMBINATION argument, not just lists designating
method combinations. (lp#936513)
* bug fix: run-program no longer unconditionally uses /tmp/ for temporary
files. (lp#968837).
* bug fix: restore build on solaris/sparc. (lp#1008506)
* bug fix: an issue with LDB in the PowerPC backend has been resolved;
this fixes an issue found with cl-postgres (thanks to Tomas Hlavaty).
* bug fix: compiler-macro lambda-lists specifying non-keyword symbols
as keyword arguments no longer accidentally match unevaluated symbols
against them.
* bug fix: FORMAT used to loop infinitely in some cases when a COLINC
parameter was zero, now it signals an error. (lp#905817, fixed since
1.0.56.19)
* bug fix: run-program with :pty t no longer makes the pty as the process's
controling terminal.

changes in sbcl-1.0.57 relative to sbcl-1.0.56:
* RANDOM enhancements and bug fixes:
** bug fix: the range and distribution of random integers could be
catastrophically wrong when the compiler derived the type of its
argument as a disjoint set of small integers.
** bug fix: the distribution of random integers is now completely
uniform even when the specified limit is not a power of two.
(Previously some values could be about 0.1 % more probable than
others in the worst case.)
** RANDOM on large integer arguments is generally faster and conses
less than before; this is visible for fixnums above a length of
about 24 bits, but extremely so for bignums: the old implementation
used time and space quadratical in the size of the argument there,
the new one is linear.
* enhancement: redesigned protocol for quitting SBCL. SB-EXT:EXIT is the new
main entry point, SB-EXT:QUIT is deprecated.
* enhancement: additions to the SB-THREAD API: RETURN-FROM-THREAD,
ABORT-THREAD, MAIN-THREAD-P, and MAIN-THREAD.
* enhancement: FASL loading no longer grabs the world-lock.
* enhancement: GENCGC reclaims space more aggressively when objects being
allocated are a large fraction of the total available heap space.
(lp#936304)
* enhancement: backtraces show the correct number of arguments for frames
called with too many arguments.
* enhancement: support for abort(3), exit(3), and _exit(2) has been added to
SB-POSIX.
* enhancement: ASDF has been updated 2.21.
* optimization: fewer uses of full calls to signed modular functions.

(Thanks to James Knight, #911027)
* enhancements
+ SBCL can now be built using Clang.
+ ASDF has been updated 2.20.
* bug fix: compiler errors when weakening hairy integer types. (#913232)

|
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)
* bug fix: attempts to stack allocate a required argument to a
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-1.0.53 relative to sbcl-1.0.52:
* enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
(signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
* enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
* minor(?) incompatible(?) change: The default fixnum width on 64-bit
targets is now 63 bits (up from 61).
* enhancement: DESCRIBE now reports a lambda-list and source location
for complext setf-expanders.
* bug fix: PUSH, PUSHNEW, POP, REMF, INCF, DECF, DEFINE-MODIFY-MACRO,
GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
of multiple-valued places to be set to NIL, instead of signalling an
error (per a careful reading of CLHS 5.1.2.3).
* bug fix: floating-point traps now work on darwin/x86 and /x86-64.
* bug fix: repair crash in x86oid darwin signal handling emulation
when built with certain compilers.
* bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
rotation arguments on x86-64. (lp#882151)
* bug fix: low-level control flow optimisations could result in bogus
code in functions with tail and non-tail calls to local functions on
x86oids. (lp#883500)
* bug fix: on SPARC/:sb-unicode, avoid crashing the assembler by trying
to emit literal characters > (code-char 4095), for comparisons with
constant characters.
* bug fix: ROOM reported only the low 32 bits of dynamic space usage
on 64 bit platforms. (lp#881445)
* bug fix: DELETE-FILE did not MERGE-PATHNAMES, making it possible to
delete the wrong file when using relative pathnames. (lp#882877)
* bug fix: optimized SEARCH of vectors-on-vectors mishandled zero-length
sequences and :KEY NIL.
changes in sbcl-1.0.52 relative to sbcl-1.0.51:
* enhancement: ASDF has been updated to version 2.017.
* enhancement: the --core command line option now accepts binaries with
an embedded core.
* enhancement: when built with :sb-core-compression, core files (regular
or executable) can be compressed with zlib. Use the :COMPRESSION
argument to SAVE-LISP-AND-DIE to specify a compression level.
* enhancement: --[no-]merge-core-pages determines whether the runtime
hints the operating system that identical core pages between SBCL
processes should share the same physical memory. Default is to only
enable this for compressed cores.
* optimization: SLEEP no longer conses.
* optimization: *PRINT-PRETTY* no longer slows down printing of strings
or bit-vectors when using the standard pretty-print dispatch table.
* bug fix: non-function FTYPE declarations no longer cause a compiler-error.
(lp#738464)
* bug fix: compiler-errors causes by MEMBER types in conjunction with with
AREF, CHAR, etc. (lp#826971)
* bug fix: compiler-errors causes by integer arguments with composed of
multiple ranges to ARRAY-IN-BOUNDS-P. (lp#826970)
* bug fix: ,@ and ,. now signal a read-time error for certain non-list
expressions. (lp#770184)
* bug fix: complex single float literals are correctly aligned when used
as arguments of arithmetic operators.
* bug fix: on 32-bit platforms, rounding of double floats larger than a
fixnum is correct. (reported by Peter Keller)
* bug fix: stray FD-HANDLERs are no longer left lying around after unwinds
from RUN-PROGRAM. (lp#840190, reported by Dominic Pearson; fix from Max
Mikhanosha)
* bug fix: redefining classes such that slots with custom allocation are
added or removed works again.

MAKE-SOCKET-STREAM if using SERVE-EVENT.
* enhancement: added support for socket keepalive timeout intervals
and probe counts on Linux.
* enhancement: building 32-bit SBCL on Linux/x86-64 now works without a

(lp#549673)
* bug fix: SSE comparison instructions can be disassembled even when one
operand is in memory. (lp#814702)

floats no longer signals a SIMPLE-TYPE-ERROR, reported by Lutz Euler.
(lp#819269)

backwards incompatible change in 1.0.48.27)
* bug fix: occasional debugger errors in when a type-error occured in a

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

** 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.

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)

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: sense of SLOT-BOUNDP-USING-CLASS was inverted in a MAKE-INSTANCE
optimization. (regression from 1.0.45.18/1.0.46.15)

(lp#721457)
* bug fix: memory fault from printing a malformed simple-condition.
(lp#705690)

* enhancement: :NOT-NULL option has been added to alien C-STRING type to indicate
that NIL/NULL is excluded from the type.

arbitrary objects.
* optimization: SLOT-VALUE &co are faster in the presence of SLOT-VALUE-USING-CLASS
and its compatriots.

* bug fix: SB-DEBUG:BACKTRACE-AS-LIST guards against potentially leaking
stack-allocated values out of their dynamic-extent. (lp#310175)
* bug fix: attempts to use SB-SPROF for wallclock profiling on threaded
x86-64 builds caused a type-error.
* bug fix: calling COMPILE with something else than a lambda-expression as the
second argument reports a more sensible error. (lp#718905)
* bug fix: invalid combinations of :PREDICATE and :TYPE options in DEFSTRUCT
are detected. (lp#520607)
* bug fix: constant keyword argument checking didn't take :ALLOW-OTHER-KEYS
into account.
* bug fix: SLOT-BOUNDP information is correct during MAKE-INSTANCE in the
presence of (SETF SLOT-VALUE-USING-CLASS) and SLOT-BOUNDP-USING-CLASS
methods. (regression from 1.0.45.18)
* bug fix: INITIALIZE-INSTANCE :AROUND methods supplying initargs via
CALL-NEXT-METHOD work correctly. (regression from 1.0.45.19)
* bug fix: several foreign functions accepting string also accepted NIL and
consequently caused a memory fault at 0 now signal a type-error instead.
(lp#721087)
* bug fix: under rare circumstances, constraint propagation could rewrite a
variable reference to refer to a variable not in scope, causing an error
during physical environment analysis when attempting to close over the
variable. (lp#551227)
* bug fix: SIMPLE-CONDITION :FORMAT-CONTROL defaults to NIL.

Changes in sbcl-1.0.46 relative to sbcl-1.0.45:
* enhancement: largefile support on Solaris.
* enhancement: SB-PROFILE:REPORT now supports :LIMIT and :PRINT-NO-CALL-LIST
arguments (lp#710017)
* enhancement: SB-PCL:+SLOT-UNBOUND+ is exported, making it possible to
distinguish unbound instance slots when using STANDARD-INSTANCE-ACCESS
&co. (lp#718039)
* optimization: ERROR and CERROR are approximately 5 times faster.
* optimization: optimized constructors are used for MAKE-INSTANCE of classes
with applicable non-standard (SETF SLOT-VALUE-USING-CLASS),
SLOT-BOUNDP-USING-CLASS, and INITIALIZE-INSTANCE :AROUND methods, speeding
up instance creation in those cases.
* optimization: arithmetic operations with multiple constant arguments in now
have them reduced at compile-time. (lp#676414)
* optimization: determining current character position on string-streams for
pretty-printing was overly slow.
* bug fix: local tail calls to DYNAMIC-EXTENT functions can no longer cause
lifetime analysis to overwrite closed-over variables (lp#681092).
* bug fix: encoding errors from some multibyte external formats such as EUC-JP
were not handled correctly (lp#713063).
* bug fix: printing waitqueue objects without setting *PRINT-CIRCLE* to T is now
safe (lp#673630).
* bug fix: Solaris/x86-64 wasn't getting built with lutex support by
mistake. (lp#667297).
* bug fix: CONSTANTLY generated functions had bogus lambda-lists. (lp#713626)
* bug fix: RUN-PROGRAM :PTY option was racy on OpenBSD. (lp#669485)
* bug fix: UNINTERN takes a symbol, not a symbol designator -- could previously
unintern the wrong symbol with the same name. (lp#693796)
* bug fix: COPY-PPRINT-DISPATCH always has access to a pristine table,
making it possible to restore the initial table if it has been messed up.
(lp#678409)
|
|
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.

changes in sbcl-1.0.42 relative to sbcl-1.0.41
* build changes
** Cross-compilation host is now specified to make.sh using
command-line argument --xc-host=<command> instead of a positional
argument. (thanks to Daniel Herring)
** Install location can be specified to make.sh using command-line
argument --prefix=<path>. (lp#550889s, thanks to Daniel Herring)
* optimization: The default implementation of
COMPUTE-DISCRIMINATING-FUNCTION does much less wasted work.

by multithreaded code. See documentation for details.
* enhancement: Experimental support for threading on Linux/PPC.
* bug fix: RENAME-PACKAGE returns the package. (Thanks to Eric Marsden)

Changes in sbcl-1.0.41 relative to sbcl-1.0.40:
* optimization: validity of observed keyword initargs to MAKE-INSTANCE is
cached, leading to many fewer expensive calls to
COMPUTE-APPLICABLE-METHODS.
* optimization: in the (unoptimized) general method for MAKE-INSTANCE on a
CLASS argument, search for and call an appropriate optimized ctor function
if it exists.
* bug fix: WRITE always returns the correct value.

Changes in sbcl-1.0.40 relative to sbcl-1.0.39:
* bug fix: readdir now works on :inode64 darwin builds (lp#592897)
* bug fix: Name conflicts between symbols passed as arguments to a single
call to IMPORT no longer add multiple symbols with the same name to the
package (detectable via DO-SYMBOLS).
* bug fix: support building without the dlshim on darwin x86 and x86-64
(lp#533470).
* bug fix: TRACE :ENCAPSULATE NIL now works on ppc/linux.

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.
* new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
conditions to defer the deadline for forever.

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: 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.
* bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
(lp#569404)
* bug fix: RANDOM-STATE can be printed readably again.
* bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
* bug fix: Using EQL with non-constant values of constant type (e.g. EQL
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)
* optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use
pre-allocated temporary vectors. (lp#496249)

* enhancement: Can now build with ud2 instead of int3 as trap instruction on
all x86oid platforms with :UD2-BREAKPOINTS target feature.
* bug fix: Breakpoints now work when using ud2 instead of int3 as trap
instruction (tested on x86oid linux with ud2-breakpoints).
* bug fix: slam.sh now works on win32.
* bug fix: better differences of numeric types. (lp#309124)

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)

News
changes in sbcl-1.0.35 relative to sbcl-1.0.34:
* optimization: ROUND with a single single-float or double-float argument
is properly inlined when possible.
* optimization: Slightly better code is generated for integer<->float
conversions and for single-float<->double-float conversions on x86-64.
* optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient
code for 32-bit and 64-bit rotations on x86-64.
* bug fix: The install script changes the ownership of directories as well
as files for contrib modules using asdf. (thanks to Eugene Ossintsev;
launchpad bug lp#508485)
* bug fix: TRUNCATE with a single single-float or double-float argument is
properly inlined when possible. (launchpad bug lp#489388)
* bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
no longer causes a compiler error on x86 and ppc.
* bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
always relative to *READTABLE* rather than the passed argument.
changes in sbcl-1.0.34 relative to sbcl-1.0.33:
* minor incompatible change: threading support is now enabled by default
on x86[-64] Linux.
* enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
builtin types.
* enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
are now caught and reported just like errors during macroexpansion.
* enhancement: SB-POSIX now provides access to tcdrain(), tcflow(),
tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James)
* enhancement: ASDF systems can now depends on SB-QUEUE.
* fixes and improvements related to Unicode and external formats:
** bug fix: error handling and restart usage in the ucs-2 external format
has been improved.
** there is now an implementation of the ucs-4 external format.
** the utf-16 and utf-32 external formats are supported.
* bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings
in the environment. setenv() and unsetenv() are also provided. (reported by
Fare Rideau; launchpad bug lp#460455)
* bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style
loading. This ensures sensible errors for .FASL files from other
implementations on case-insensitive filesystems. (reported by Willem
Broekema; launchpad bug lp#489417)
* bug fix: #p"\\\\" can now be read without error on Win32. (reported by
Willem Broekema; launchpad bug lp#489698).
* bug fix: some minor code rearrangements to reenable warning-free building
from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
* bug fix: PRINT-OBJECT for clos instances respects the right margin when
pretty printing
* bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by
Attila Lendvai)
changes in sbcl-1.0.33 relative to sbcl-1.0.32:
* new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
* improvement: support O_LARGEFILE access to files larger than 2GB on
x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080)
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
definitions for methods specializing on the passed class itself.
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
definitions for methods specializing on the passed class itself, or on
subclasses of it.
* new build flag: :sb-xref-for-internals; SBCL will collect xref information
about itself during the build (e.g. for M-? in Slime), if this flag is
enabled in customize-target-features.lisp. This will increase the core
size by about 5-6mb, though, so it's mostly interesting to SBCL
developers.
* new feature: various GENCGC tuning parameters have been experimentally
documented and exported from SB-EXT. See documentation for details.
* fixes and improvements related to Unicode and external formats:
** the Unicode character database has been upgraded to the
Unicode 5.2 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** improvement: restarts for providing replacement input/output on coding
errors for fd-stream external formats.
** improvement: where :<encoding> is a keyword corresponding to an
external format the system supports, it is now possible to specify
(:<encoding> :replacement <character>) as an external format which will
automatically substitute <character> on encoding or decoding errors for
streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
lp#317072)
** improvement: the file streams underlying the standard streams (such as
*STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
which uses the replacement mechanism to handle encoding errors,
preventing various infinite error chains and unrecoverable I/O
confusion.
** minor incompatible change: the utf-8 external format now correctly
refuses to encode Lisp characters in the surrogate range (char-codes
between #xd800 and #xdfff).
** fix a typo preventing conversion of strings into octet vectors
in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
lp#471689)
** fix a bug in the octet multibyte handling of decoding errors and the
USE-VALUE restart. (launchpad bug lp#314939)
** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
restart on fd-stream decoding errors.
** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
error is near the end of file.
** fix a double-error case in unibyte octet conversions, when the first
use of USE-VALUE is ignored.
** fix bugs in handling of undefined code points in unibyte encodings.
** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent
streams after an UNREAD-CHAR.
* enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
object is allocated in a boxed region of dynamic space.
* enhancement: SB-POSIX:FORK now signals an error if an attempt to
fork with multiple Lisp threads running is made, instead of going
ahead with unpredictable consequences. (reported by Leslie Polzer)
* bug fix: uses of slot accessors on specialized method parameters within
the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
error while finalizing the class. This fix may cause classes with slot
accessors to be finalized later than previously. (reported by Lars Rune
Nøstdal; launchpad bug lp#473699)
* bug fix: restore buildability on the MIPS platform. (regression from
1.0.30.38, reported by Samium Gromoff)
* bug fix: inspecting closures is less likely to fail with a type error.
* bug fix: no timer starvation when setting the system clock back.
(launchpad bug lp#460283)
* bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
standard pprint dispatch table as specified by CLHS.
* bug fix: give CLISP a hint about a type declaration to enable it to build
the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
bug lp#396597)
* bug fix: correctly dump literal objects in defaulting forms of arglists.
(reported by Attila Lendvai; launchpad bug lp#310132)
* bug fix: distinguish in type specifiers between arrays that might be
complex and arrays that are definitely complex. (launchpad bug lp#309129)
* bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
type. (reported by Levente Mészáros; launchpad bug lp#485972)
* bug fix: setting the value of a symbol-macro within a method in the
presence of type declarations works properly again. (reported by Iban
Hatchondo; launchpad bug lp#485019)
changes in sbcl-1.0.32 relative to sbcl-1.0.31:
* optimization: faster FIND and POSITION on strings of unknown element type
in high SPEED policies. (thanks to Karol Swietlicki)
* optimization: faster CONCATENATE 'STRING in low SPEED policies (reported
by David Vázquez)
* improvement: better error signalling for bogus parameter specializer names
in DEFMETHOD forms (reported by Pluijzer)
* bug fix: DELETE-FILE once again works on logical pathnames (regression
since 1.0.30.49)
* bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified
incorrectly.
* bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS
removes previous default initargs (reported by Lars Rune Nøstdal and
Samium Gromoff)
* bug fix: correct WHO-CALLS information for inlined lambdas with complex
lambda-lists. (reported by Peter Seibel)
* bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work
correctly when starting from an executable core without saved runtime
options (reported by Faré Rideau, thanks to Zach Beane)
* bug fix: (SETF SLOT-VALUE) signalled a warning which should have been
an optimization note instead. (reported by Martin Cracauer)
* bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin)
* bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a
new process group if it doesn't need to share stdin with the sbcl
process. (thanks to Leslie Polzer)
* bug fix: SATISFIES could be misoptimized to refer to a local function.
(reported by Stanislaw Halik)
changes in sbcl-1.0.31 relative to sbcl-1.0.30:
* improvement: stack allocation is should now be possible in all nested
inlining cases: failure to stack allocate when equivalent code is manually
open coded is now considered a bug.
* improvements related to Unicode:
** the Unicode character database has been upgraded to the
Unicode 5.1 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** the system now recognizes and produces names for Unicode Hangul
syllable characters.
** the EBCDIC-US external-format is now supported for octet operations
(as well as for stream operations).
* new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
be used to output toplevel compile-time effects into a separate .CFASL
file.
* optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
actually needed.
* optimization: TRUNCATE on known single- and double-floats is upto 25%
faster.
* optimization: division of floating point numbers by constants uses
multiplication by reciprocal when an exact reciprocal exists.
* optimization: multiplication of single- and double-floats floats by
constant two has been optimized.
* optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
sufficient type information is available. (thanks to Leslie Polzer)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names on
known structure objects are as efficient as defstruct generated accessors.
* optimization: unused vector creation can now be optimized away.
* improvement: ASDF systems can now depends on SB-INTROSPECT.
* improvement: a STYLE-WARNING is signalled when a generic function
clobbers an earlier FTYPE proclamation.
* improvement: the compiler is able to track the effective type of
generic function across method addition and removal even in the
absence of an explicit DEFGENERIC.
* improvement: DESCRIBE now reports on symbols naming undefined
but assumed or declared function as well.
* improvement: recompilation of systems using SB-GROVEL now works
(thanks to Leslie Polzer)
* improvements to SB-CLTL2 (thanks to Larry D'Anna):
** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have been
documented.
** AUGMENT-ENVIRONMENT and DEFINE-DECLARATION have been implemented.
** DECLARATION-INFORMATION now supports declaration name DECLARATION as
well as user defined declaration names.
** VARIABLE-INFORMATION is now aware of alien variables.
* improvement: improved address space layout on OpenBSD (thanks to Josh
Elsasser)
* improvement: pretty-printing of various Lisp forms has been improved
(thanks to Tobias Rittweiler)
* bug fix: calls to DECODE-FLOAT and INTEGER-DECODE-FLOAT whose value was
unused were deleted in safe code. (reported by John Fremlin)
* bug fix: a failing AVER compiling certain MAKE-ARRAY forms. (reported
by James Wright)
* bug fix: some out-of-line array predicates were missing (reported by
Stelian Ionescu)
* bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
Larry D'Anna)
* bug fix: a failing AVER in %ALLOCATE-CLOSURES conversion has been fixed
(thanks to Larry D'Anna)
* bug fix: SLEEP supports times over 100 million seconds on long on OpenBSD
as well. (reported by Josh Elsasser)
* bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
leading to possible attempts to delete the same file twice. See docstring
on DELETE-FILE for details. (reported by John Fremlin)
* bug fix: DELETE-FILE once again deletes the file named by the pathname
designator argument, rather than its truename. (reported by Luis
Oliveira)
* bug fix: the low-level debugger had 32-bit assumptions and was missing
information about some array types. (thanks to Luis Oliveira)
* bug fix: moderately complex combinations of inline expansions could
be miscompiled if the result was declared to be dynamic extent.
* bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the
form (+ <variable> <integer>) were miscompiled under certain
circumstances.
* bug fix: in some cases no compiler note about failure to stack allocate
was emitted, even if the objects were in fact heap allocated.
* bug fix: minor violation of "otherwise inaccessible" rule for stack
allocation could cause objects users might reasonably expect to
be heap allocated to be stack allocated.
* bug fix: DESCRIBE signalled an error for generic functions under
certain circumstances. (thanks to Leslie Polzer)
* bug fix: Fixed spelling of an error message.

If this uncovers bugs, those should be fixed, don't mask them.

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

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

that this update will close a couple of PRs that have been filed
against the SBCL package.
|
|
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.

Feel free to fix them...

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...

rather than PKG_FAIL_REASON, so that they provide useful error
messages in build logs, and so that they continue to work on platforms
where they aren't broken.

3.0. If one of these is important to you, please fix it in time
for pkgsrc-2006Q1, or it may be removed.
