sbcl 1.0.57

Juho Snellman — 2012-05-20T21:36:38

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.

sbcl 1.0.56

Juho Snellman — 2012-04-13T02:02:02

SBCL 1.0.56 has been released, with the following changes:

changes in sbcl-1.0.56 relative to sbcl-1.0.55:
  * bug fix: fix copy-structure.  When copying from stack to heap, garbage
    could end up in the heap making GC unhappy.
    (Thanks to James Knight, lp#911027)
  * enhancements
    ** SBCL can now be built using Clang.
    ** ASDF has been updated 2.20.
  * bug fix: compiler errors when weakening hairy integer types. (lp#913232)
  * bug fix: don't complain about a too-hairy lexical environment for
inlining
    when the function has never been requested for inlining.  (lp#963530)

sbcl 1.0.55 released

Juho Snellman — 2012-01-09T04:16:02

changes in sbcl-1.0.55 relative to sbcl-1.0.54:  * 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. (lp#891268)  *
enhancement: SB-EXT:PRINT-UNREADABLY restart for PRINT-NOT-READABLE
conditions can be

Juho Snellman — 2011-12-05T00:34:45

SBCL 1.0.54 has been released with the following changes:

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.

sbcl 1.0.53 has been released

Juho Snellman — 2011-11-06T22:33:57

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

sbcl 1.0.52 released

Juho Snellman — 2011-10-09T04:54:24

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

sbcl-1.0.51

Juho Snellman — 2011-08-21T00:28:37

changes in sbcl-1.0.51 relative to sbcl-1.0.50:
  * minor incompatible change: SB-BSD-SOCKET socket streams no longer
    participate in SERVE-EVENT by default: pass :SERVE-EVENTS T to
    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
    chroot. (Use "SBCL_ARCH=x86 sh make.sh" to build.)
  * enhancement: added new toplevel options --quit and --non-interactive
    (lp#822712).
  * enhancement: the Windows port of SBCL now builds and runs on Wine
    (thanks to Anton Kovalenko).
  * enhancement: more, and more correct, SSE instruction definitions on
    x86-64 (thanks to Alexander Gavrilov).
  * enhancement: SB-EXT:SPIN-LOOP-HINT assembles to an instruction designed
    to help the processor execute spin loops, when applicable.  Currently
    implemented for x86 and x86-64.

    COMPILATION-SPEED > SPEED.
  * enhancement: SB-ALIEN exports alien type specifiers SIZE-T and OFF-T.
  * enhancement: debugger understands &MORE arguments better.
  * optimization: extracting bits of a single-float on x86-64 has been
    optimized. (lp#555201)
  * optimization

  * optimization: optimized constructors are used for MAKE-INSTANCE of
classes
    with applicable non-standard (SETF SLOT-VALUE-USING-CLASS),

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.
  * enhancement: Explicit memory barrier operations are now available for use
    by multithreaded code.  See documentation for details.
  * enhancement: Experimental support for threading on Linux/PPC.

Hi,

I've just tagged and uploaded sbcl-1.0.41, whose release notes are
appended below.

Cheers,

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.

sbcl-1.0.39 released

Christophe Rhodes — 2010-05-29T19:45:07

Hi,

I just tagged sbcl-1.0.39, and uploaded source and an x86/linux binary
to Sourceforge.  Release notes appended to this message.  Enjoy.

Best,

Christophe

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 situatio
