sbcl Debian release 2:1.1.11-1

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)

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)

Debian release 2:1.1.6-2

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.

Debian release 2:1.1.6-1

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: 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)

    built without pseudo-atomic sequences and their run-time overhead.
  * enhancement: Threads created outside of Lisp can enter Lisp through
    alien callbacks and appear as Lisp threads for the duration of that
    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
    improvements.  (Thanks to Dmitry Kalyanov and Anton Kovalenko.)

    on Windows.  (Thanks to Anton Kovalenko.)
  * enhancement: The Windows backend now supports the x86-64 platform.
    (Thanks to Anton Kovalenko.)
  * bug fix: fasls are now once again directly executable (on platforms
    supporting shebang lines, with a suitably-installed sbcl).

    be lower-case, to minimize differences between POSIX and Windows.

Debian release 2:1.1.2-1

Debian release 2:1.1.1.0-3

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)

    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.
  * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
    (thanks to SANO Masatoshi)
  * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
    :JUNK-ALLOWED was true.
  * bug fix: type derivation inferred overly conservative types for
    unions of array types. (lp#1050768)

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.

    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)

Debian release 2:1.0.58.0-1
