sbcl-1.1.7 released

Christophe Rhodes — 2013-04-29T16:22:42

Dear all,

I have just released sbcl-1.1.7; release notes are appended to this
message.  Share and enjoy.

Best wishes,

Christophe

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 'functio

Re: sbcl-1.1.6 released

Christophe Rhodes — 2013-04-03T06:45:52


One thing which is definitely a regression, though not sufficiently
clearly revealed by testing during the freeze period, is that sbcl-1.1.6
cannot compile SVREF and (SETF SVREF) of symbol macros.  This
unfortunate bug can make it less than suitable some uses, and affects a
number of libraries in quicklisp among other things.

Best wishes,

Christophe

sbcl-1.1.6 released

Christophe Rhodes — 2013-03-29T20:21:29

Dear all,

I've just released sbcl-1.1.6.  There have been reports about some
concurrency tests failing on windows, and some garbage collection
troubles on PowerPC/Linux with the generational garbage collector: users
of those particular systems may wish to exercise extra care in
upgrading, though it's not clear that either of these issues is a
regression.

Changes from sbcl-1.1.5 are appended to this message.

Best wishes,

Christophe

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.
    (

sbcl-1.1.5 released

Christophe Rhodes — 2013-02-26T13:18:02

Dear all,

I've just released sbcl-1.1.5 in git and to sourceforge; as usual,
binaries for various platforms will trickle in over the next few days.
The release notes are appended to this message.

Best wishes,

Christophe

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 d

sbcl-1.1.4 released

Christophe Rhodes — 2013-01-30T21:04:49

Just in time for the end of the month, I have released sbcl-1.1.4.  Of
note, the sb-sprof contrib will now not fail its self-tests on Darwin
any more, unlike sbcl-1.1.3; this does not mean that the underlying
signal-related issue has been fixed, merely that the test has been
disabled on that platform to allow the somewhat fragile utility to
nevertheless be available for users.

I have appended the release notes below.

Best wishes,

Christophe

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

sbcl-1.1.3 released

Christophe Rhodes — 2012-12-31T22:20:42

Dear all,

I have just performed the release dance for SBCL 1.1.3.  Do please note
that there has been a report of a regression in the display of
backtraces when an interrupt happens during condition-wait on OS X -- if
this affects you and you can help reproduce or isolate the problem, that
would be most helpful.  Otherwise, the release notes are appended to
this message; we would be interested in feedback, particularly from
Windows users (as the mainline approaches some of the functionality of
Anton Kovalenko's fork).

Happy New Year,

Christophe

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.)
  * enhancement: STDCALL alien callbacks. (Thanks to Anton Kovalenko.)
  * enhancement: Safepoint builds on POSIX platforms can now optionally be
    built without pseudo-atomic sequences and their run-time overhead.

sbcl-1.1.2 released

Christophe Rhodes — 2012-12-01T14:25:15

Dear all,

I have just done the release dance for sbcl-1.1.2; an x86-64/Linux
binary (and the source code) are now available at sourceforge.  The
release notes are appended to this message; please consume responsibly,
taking particular note of the new arrangements on Windows.

Best wishes,

Christophe

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. (T

sbcl-1.1.1 released

Christophe Rhodes — 2012-11-02T14:45:56

Dear all,

I've just released sbcl-1.1.1.  A couple of things to note: firstly
there have been some reports of heap corruption under some circumstances
on the windows build, which is now newly threaded by default; users of
SBCL on windows might wish to be as circumspect as they usually are when
dealing with new releases.  Windows users might wish to note the plan to
drop support for unthreaded builds from the next release, and use this
release cycle to make sure that any potential problems are discovered in
advance of the next release.

Secondly, I meant to build the x86-64/Linux binary in a chroot but
forgot, meaning that the binary links to a relatively new libc version
rather than an older one; if this is a problem for anyone, a rebuild
starting from the x86-64/Linux binary for sbcl-1.1.0 should be
straightforward.

Best wishes,

Christophe

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.)
  * opti

sbcl-1.1.0 released

Christophe Rhodes — 2012-10-02T11:15:21

Hi,

I've just released sbcl-1.1.0; the release notes are below.  Don't get
too excited about the new version number; its main conceptual
significance is it's a new version number to indicate the new version
numbering system, which starts with "1.1" -- in other words, this is a
"monthly" release just like any other.

On the other hand, this is a .0 release in the sense that it's my first
for a while, and it's possible that something unnoticed has gone wrong.
Please let me know if there's something wrong with the release that
needs correcting.

Best wishes,

Christophe

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 fe

SBCL 1.0.58 released

Juho Snellman — 2012-08-06T22:16:27

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 c

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)  *

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:

     Many thanks to generous donors!)
    ** Threading is now more reliable on non-Linux platforms. We still don't

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

SBCL 1.0.51 has been released, with the following changes:

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.

sbcl 1.0.50

Juho Snellman — 2011-07-11T23:27:45

SBCL 1.0.50 has been released (git tag sbcl-1.0.50), source and Linux binary
tarballs available.

changes in sbcl-1.0.50 relative to sbcl-1.0.49:
  * enhancement: errors from FD handlers now provide a restart to remove
    the offending handler.
  * enhancement: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works on structure
    copiers as well.
  * enhancement: location of user or system initialization file can now
easily
    be customized for saved cores. See: SB-EXT:*USERINIT-PATHNAME-FUNCTION*
    and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*.
  * enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for
    the thunk, as a keyword argument, :arguments.
  * enhancement: constraint propagation is simplified (and sped up) when
    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
