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
    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.

  * 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

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.
  * bug fix: Fix function/macro redefinition warnings when building with
    clisp.  (lp#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.

sbcl.1.0.38

sbcl_1_0_38

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.
  * 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: 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.

    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)
  * bug fix: Fix compiler error involving MAKE-ARRAY and IF forms
    in :INITIAL-CONTENTS. (lp#523612)
  * bug fix: FUNCTION-LAMBDA-EXPRESSION lost declarations from interpreted
    functions. (lp#524707)
  * bug fix: bogus style warnings from certain (SETF SLOT-VALUE) and
    WITH-SLOTS usages during compilation.
  * bug fix: SB-C::CLASS-INFO now prints correctly. (lp#514762)
  * 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)
  * bug fix: arrays declared intersection and union types can have their
    upgraded element type derived. (lp#316078)
  * bug fix: SB-SPROF allocation profiling for all threads failed to profile
    threads started during profiling. (lp#472499)
  * bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
    (lp#535658)
  * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
    SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)
  * bug fix: Comma inside a backquoted array or structure resulted in nonsense
    values instead of signaling an error. (lp#309093)

    (lp#528807)
  * bug fix: More consistent warnings and notes for ignored DYNAMIC-EXTENT

    &REST and &KEY in lambda-list caused miscompilation (lp#458354)
  * bug fix: WHO-CALLS information for source-transformed and compiler-macro
    expanded calls (lp#542174)
  * bug fix: more accurate WHO-MACROEXPANDS information; point into rather
    than just at toplevel form.

sbcl.1.0.36

sbcl_1_0_36

changes in sbcl-1.0.36 relative to sbcl-1.0.35:
  * 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 lp#310116)
  * bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set the
    FILE-POSITION of the stream being read from.  (launchpad bug lp#491087)
  * bug fix: Fix grammar and style issues for the docstrings of
    printer-related variables and functions.  (Thanks to mon_key; launchpad
    bug lp#518696)
  * bug fix: Fix compilation on chenygc platforms. Thanks to Larry Valkama and
    Bruce O'Neel.
  * bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a deadline twice
    in a row even though a handler defered the deadline long into the
    future. (lp#512914)
  * bug fix: A deadline handler was run without interrupts enabled for a
    deadline signaled within SB-THREAD:CONDITION-WAIT. That could result
    in infinitely spinning, non-killable threads.
  * bug fix: Backtrace from internal-errors on x86-64 os x was truncated
    before reaching the erring stack frame.
  * bug fix: Fix type derivation for EXPT when raising a fixnum to a
    real power.  (launchpad bug lp#525949)
  * bug fix: Fix SB-EXT:GENERATION-* accessors for generations > 0 on

sbcl.1.0.35

sbcl_1_0_35

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.

sbcl.1.0.34

sbcl_1_0_34

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)
