sbcl_1_0_44

changes in sbcl-1.0.44 relative to sbcl-1.0.43:
  * 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. (thanks to
       Kalyanov Dmitry)
    ** bug fix: run-sbcl.sh now works on Cygwin. (thanks to Kalyanov Dmitry)
  * bug fix: compiler failed to derive the result-type of MAKE-ARRAY as
    (AND VECTOR (NOT SIMPLE-ARRAY)) when appropriate. (lp#309130)
  * bug fix: (THE (VALUES ...)) in LOAD-TIME-VALUE caused a compiler-error.
    (lp#646796)

  * bug fix: overeager character buffering could cause input to block
    spuriously when reading from a pipe (lp#643686)
  * bug fix: more efficient timer expiry should avoid starvation on systems
    where number of SIGALRMs per second is restricted. (lp#375515)
  * bug fix: non-unicode builds no longer fail (broken since 1.0.36.15).
  * bug fix: compile-times no longer scale linearly with the size of
    quoted lists in source-code. (lp#654289)
  * bug fix: better errors for unknown external-formats in OPEN. (lp#561974)
  * bug fix: DEBUG>SPEED no longer degrades ALIEN-FUNCALL performance quite
    so badly. (lp#654485)
  * bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCES-BY-NAME no longer signals
    an error for eg. STRUCTURE. (lp#458015)
  * bug fix: LOOP WITH NIL = ... signalled an unused variable style-warning.
    (lp#613871, thanks to Roman Marynchak)
  * bug fix: more reliable &REST list type derivation. (lp#655203)
  * bug fix: PPRINT-LOGICAL-BLOCK multiply-evaluated :PER-LINE-PREFIX,
    and issued pointles code-deletion notes for it, :PREFIX, and :SUFFIX.
  * bug fix: the compiler didn't utilize the proclaimed ftype for functions
    also declared NOTINLINE. (lp#655581)
  * bug fix: the compiler could attempt to emit constant left shifts of
    greater value than n-word-bits. (lp#309063)
  * bug fix: (SETF SYMBOL-FUNCTION) and (SETF FDEFINITION) clear derived
    type information for the function being set. (lp#659220)
  * bug fix: the system used to signal bogus STYLE-WARNINGs when functions
    containing self-calls were recompiled with a new signature, and failed
    to warn when a self-call using the old signature was left in. (lp#655126)
  * bug fix: incorrect FILE-POSITION on streams opened using :EXTERNAL-FORMAT
    :DEFAULT when the default external had character size other than 8 bits.
    (lp#657183)
  * bug fix: derived types of functions in the same file were implicitly
    trusted, leading to potential heap corruption when those function were
    defined incompatibly. (lp#657499)
  * bug fix: existing ASDF source registries are ignored when building
    contribs (lp#659105)
  * bug fix: short-form DEFSETF checks that the second argument is a symbol
    (lp#655824, thanks to Roman Marynchak)
  * bug fix: (SETF MACRO-FUNCTION) clobbered macro-definitions before
    package-lock violation was detected. (lp#660752)
  * bug fix: the system can store different docstrings for a single function
    under different names. (lp#661631, regression from 1.0.29.24)
  * bug fix: source-locations of DEFGENERIC forms weren't getting recorded
    properly. (lp#384801)
  * bug fix: (COERCE X '(SIMPLE-VECTOR 5)) and similar coercions to vectors
    of specified length could confuse the type derivation in unsafe code.
    (lp#655872)
  * bug fix: SB-POSIX:FORK now signals an error if an attempt to
    fork with multiple Lisp threads running is made on every platform,
    not just Darwin. (lp#451111)
  * bug fix: SB-BSD-SOCKETS and SB-SIMPLE-STREAMS could leave stale finalizers
    around when core was saved, which could cause undefined behaviour when the
    core was reified.
  * bug fix: Allow UNTRACE of functions that are no longer defined
    (lp#667657, thanks to Attila Lendvai)
  * bug fix: MAKE-ARRAY calls with invalid keyword argument lists now signal a
    compile-time warning (lp#664373, thanks to Stas Boukarev)

    ** 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

       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

    (not in launchpad, reported by sykopomp in #lispgames)
  * bug fix: package-locks failed to protect against compile-time effects of
    DEFUN when the symbol previously had a macro definition. (lp#576637)
  * bug fix: spurious ignore warnings even given (DECLARE IGNORE) in methods
    when parameter bindings mutated.  (reported by Faré Rideau; lp #611361)
  * bug fix: workaround for compiler hang in ORDER-UVL-SETS (lp#308914)
  * bug fix: evaluation in debugger REPL works using the global context when

sbcl.1.0.41

sbcl_1_0_41

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

sbcl.1.0.39

sbcl_1_0_39

changes in sbcl-1.0.39 relative to sbcl-1.0.38:
  * 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.

  * 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.

    SB-EXT:ATOMIC-INCF.
  * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
    conditions to defer the deadline for forever.
  * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
    now bivalent.
  * enhancement: errors from NO-APPLICABLE-METHOD and
    NO-PRIMARY-METHOD now have a RETRY restart available to retry the
    generic function call.
  * enhancement: SB-BSD-SOCKET improvements
    ** sockets and socket streams now have a more informative printed
       representation based on the corresponding SOCKET-NAME and
       SOCKET-PEERNAME.
    ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
       (lp#540413)
    ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
       CL:CLOSE when appropriate, and no longer disassociates the stream
       from the socket if close failed. (lp#543951)
  * improvements to the instrumenting profiler
    ** new feature: report per-function GC overhead. (thanks to John Fremlin)
    ** optimization: counters no longer use locks for the overflow mode.
    ** bug fix: whenever a profiling counter wrapped into overflow mode, it
       incurred an off-by-one miscount.
  * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
  * enhancement: improved DEFMETHOD pretty-printing.
  * enhancement: perform range reduction when arguments are too large for
    x87's transcendentals (instead of returning 0). (lp#327192)
  * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
    some of CL-PPCRE's macros. (lp#570079)
  * enhancement: our machine code is slightly less hostile to valgrind on
    x86-64.
  * enhancement: up-to-date versions of NetBSD-current are supported.  (Thanks
    to Robert Swindells and Aleksej Saushev)
  * bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
  * bug fix: a rare case of startup-time page table corruption.
  * bug fix: a semaphore with multiple waiters and some of them unwinding due
    to timeouts could be left in an inconsistent state.
  * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
  * bug fix: misoptimization of multiplication by one in
    (SB-C::FLOAT-ACCURACY 0) policies.
  * bug fix: miscounts in SB-PROFILE.
  * 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: 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.

    storage vector for multidimensional simple arrays resulting in better code
    for accessing such arrays.
