sbcl-1.3.2 released

Dear all,

I've just released sbcl-1.3.2; source and some binaries are available at
SourceForge, and more binaries will probably trickle in in the next few
days.  Noteworthy changes since the last release are appended to this
message.

It's perhaps worth highlighting that this release, and sbcl-1.3.1,
suffer from a pair of latent bugs being less latent than previously.
The symptoms of those bugs, which typically arise during compilation,
are of either an infinite loop
<https://bugs.launchpad.net/sbcl/+bug/1540123> or a heap explosion
<https://bugs.launchpad.net/sbcl/+bug/1540125>; these are unfortunately
exposed by a more uniform treatment of type checks.  In particular,
FriCAS is known to tickle these bugs, but there may be other systems
affected.

Best wishes,

Christophe

changes in sbcl-1.3.2 relative to sbcl-1.3.1:
  * enhancement: {READ,WRITE}-SEQUENCE are much faster for some combinations
    of short sequences and stream types
  * enhancement: MAKE-LIST's result can be stack-allocated on x86-64
  * bug fix: WRITE-SEQUENCE no longer fails to write lists containing integers
    to bivalent streams
  * bug fix: LOGTEST (and hence ODDP) no longer conses when given fixnum
    arguments and small bit positions.  (lp#1277690)
  * bug fix: READ-FROM-STRING compiler-macro does not permute its arguments

(belated) sbcl-1.3.1 released, no December release planned

Hi,

I appear to have forgotten to mail this list when I released
sbcl-1.3.1 -- sorry about that!  You will find the release notes
appended to this message.

I do not plan to make a release of SBCL this month unless I hear a
clamour of voices raised; instead, sbcl-1.3.2 will be released toward
the end of January.  If this causes inconvenience to anyone, please let
me know and I may revise plans accordingly.

Compliments of the season,

Christophe

changes in sbcl-1.3.1 relative to sbcl-1.3.0:
  * enhancement: SB-THREAD support for ARM64.
  * enhancement: compiling an out-of-line DEFSTRUCT constructor call
    will warn if a defaulted value is incompatible with its slot type.
  * enhancement: a local INLINE declaration on a structure constructor
    will work as intended, subject to any other factors that inhibit
    inlining, even if the DEFSTRUCT was not itself within a global
    INLINE proclamation for the named constructor
  * enhancement: SB-EXT:DYNAMIC-SPACE-SIZE is now defined for cheneygc.
  * enhancement: x86[-64] platforms support SB-EXT:CAS on structure slots
    of type SB-EXT:WORD
  * enhancement: the interleaved structure slot optimization from
    release 1.2.6 has been ported to 32-bit x86, Sparc, PowerPC, ARM64.
  * enhancement: SB-THREAD:JOIN-THREAD signals a proper error when an attempt
    is made to join the current thread

sbcl-1.3.0 released

Dear all,

New evaluator (even if it's disabled by default), new platform (even if
it's a bit difficult to get hardware for... it seemed like a good
opportunity to have a new minor version number.  I've just released
sbcl-1.3.0, and uploaded a source tarball to Sourceforge.  I'm including
a summary of changes at the end of this message; please consume
responsibly.

Best,

Christophe

changes in sbcl-1.3.0 relative to sbcl-1.2.16:
  * minor incompatible change: the environment passed to a macro/setf/deftype
    expander is not always an object of type SB-KERNEL:LEXENV.
    It can be nil, as is permissible by the standard.
  * enhancement: ported to ARM64 Linux.
  * enhancement: a new interpreter is included which has many benefits
    over sb-eval. It is disabled by default. See src/interpreter/README
    for instructions to enable it, and further details.
  * bug fix: calling COMPILE when SB-EXT:*EVALUATOR-MODE* was :INTERPRET
    would fail to perform "normal semantic processing such as macro expansion"
    as stipulated by X3J13 issue LOAD-TIME-EVAL.
  * bug fix: SB-UNICODE:CONFUSABLE-P no longer treats "<" and the empty
    string as confusable.  (lp#1504739)
  * bug fix: (ASSERT (COMPUTE-IT ...)) would expand incorrectly
    if COMPUTE-IT was a local macro that shadowed a global function.
  * bug fix: SB-POSIX:CFSETISPEED and SB-POSIX:CFSETOSPEED now work properly
    on platforms that use only the minimum specified set of fields in struct

sbcl-1.2.16 released

Dear all,

I have uploaded source and x86-64/linux binaries of sbcl-1.2.16 to
Sourceforge.  The tastefully curated list of user-visible changes is
appended to this mail; there was also a last-minute report of a problem
affecting sb-int:info and information about deprecated functions, but
this should have no impact on any user code that does not explicitly use
sb-int:info.

Best wishes,

Christophe

changes in sbcl-1.2.16 relative to sbcl-1.2.15:
  * enhancement: by default, timers with a repeat interval do not "catch up"
    by repeatedly calling their function after a clock discontinuity such as a
    suspend and resume cycle
  * bug fix: correctly restore multiple values on the stack in the presence of
    alien calls. (lp#1489590)
  * bug fix: MAKE-STRING-OUTPUT-STREAM enforces that :ELEMENT-TYPE
    is a subtype of CHARACTER.
  * bug fix: an EQL method specializer no longer causes garbage retention
    if there are no extant methods using the specializer. (lp#492851)

sbcl-1.2.15 released

Dear all,

I have released sbcl-1.2.15, and uploaded an x86-64/Linux binary to
Sourceforge; other binaries may trickle in in the next couple of days.
A summary of the changes is appended below.

Best wishes,

Christophe

changes in sbcl-1.2.15 relative to sbcl-1.2.14:
  * new feature: DEPRECATION declaration for functions, variables and types
    causes {EARLY,LATE,FINAL}-DEPRECATION-WARNING to be signaled when subject
    of the declaration is used. Integrated with DESCRIBE, DOCUMENTATION and
    SB-CLTL2:{VARIABLE,FUNCTION}-INFORMATION. Documented in the "Deprecation"
    section of the manual.
  * enhancement: ASDF updated to 3.1.5. (lp#1476867)
  * enhancement: definitions within PROGN get proper source locations when
    compiled (needs latest Slime to take advantage of this). (lp#1473147)
  * enhancement: source locations for DEFCLASS slots now point directly to the
    slot definitions, not the whole DEFCLASS form.
  * bug fix: better source location in the presence of quoted forms.
    (lp#1370561)
  * bug fix: better source locations inside backqoute. (lp#1361502)
  * bug fix: HANDLER-BIND requires that the handler-function be
    a function designator at the time of binding establishment. (lp#1480679)
  * bug fix: inlined functions surrounded by nested macrolets are properly
    inlined. (lp#309123)

sbcl-1.2.14 released

Dear all,

I have released sbcl-1.2.14.  Because of Sourceforge's continuing
partial outage, I have not been able to upload source and binaries for
download, but the version in git is tagged and the project web pages at
<http://sbcl.org/> are otherwise updated.  A summary of the changes in
this release is included below.

Best wishes,

Christophe

changes in sbcl-1.2.14 relative to sbcl-1.2.13:
  * minor incompatible change: The name of a compiled anonymous lambda
    as returned by the third value of FUNCTION-LAMBDA-EXPRESSION can have
    a lambda-list-like list following the introductory LAMBDA that is not
    in general a syntactically valid lambda list. Specifically, it won't
    retain default values, supplied-p variables, or &KEY or &AUX bindings.
  * enhancement: DESTRUCTURING-BIND has been totally reimplemented from
    scratch to address a handful of performance and correctness issues.
    Some minor behavioral differences exist regarding order of evaluation
    of default forms for unsupplied &OPTIONAL and &KEY arguments
    when nested destructuring patterns are involved.
    (lp#707556, lp#707573, lp#707578, lp#708051)
  * enhancement: DEFCONSTANT and DEFSTRUCT respect package locks. (lp#1186238,
    lp#1036716)
  * enhancement: sb-unicode:normalize-string has a new optional argument,
    FILTER, a callback which controls which decomposed characters are
    collected. Useful for stripping away diacritics more efficiently.
  * bug fix: (TYPE-OF ARRAY) for a non-simple array is subject to change

sbcl-1.2.13 released

Dear all,

I have released sbcl-1.2.13; source and an x86-64/linux binary are
available on SourceForge, and the news pertaining to this release are
appended below.

Best wishes,

Christophe

changes in sbcl-1.2.13 relative to sbcl-1.2.12:
  * incompatible change: on success, TRY-SEMAPHORE and WAIT-ON-SEMAPHORE
    return the new count
  * enhancement: WAIT-ON-SEMAPHORE accepts a decrement parameter
  * enhancement: JOIN-THREAD allows distinguishing timeout vs. abort in all
    situations
  * enhancement: On Windows DBG_PRINTEXCEPTION_C is handled and its message is
    printed. (lp#1437947)
  * bug-fix: TRUENAME works properly on broken symlinks presented as
    directories. (lp#1458164)
  * bug fix: Inlined DPB and DEPOSIT-FIELD don't interfere with left-to-right
    order of argument evaluation. (lp#1458190)
  * bug fix: (SETF (LDB (BYTE 1 2 JUNK) X) 0) is rightly rejected.
  * bug fix: DEFSETF lambda lists should not permit argument destructuring.
  * bug fix: calls to (SETF SLOT-VALUE) on a missing slot would in certain
    situations incorrectly return the result of a SLOT-MISSING method
    instead of always returning the new value. (lp#1460381)
  * bug fix: a DEFMACRO occurring not at toplevel and capturing parts of
    its lexical environment (thus being a closure) caused expressions
    involving the macro name to cause corruption in the pretty-printer

sbcl-1.2.12 release

Dear all,

I have just released sbcl-1.2.12, and uploaded the source tarball to
Sourceforge; the description of changes since the last release are
appended to this mail.

Best wishes,

Christophe

changes in sbcl-1.2.12 relative to sbcl-1.2.11:
  * minor incompatible change: the SB-C::*POLICY* variable is no longer
    a list. Code which manipulated it as such (including but not limited
    to non-bundled releases of ASDF) will need to be revised.
  * enhancement: The input stream for COMPILE-FILE implements
    STREAM-LINE-COLUMN.
  * enhancement: EVAL errors that occur by way of LOAD report the starting
    line and column number of the erring toplevel form. (lp#565247)
  * optimization: better MAP and MAP-INTO on known vector result types.
  * bug fix: Read/modify/write macros accessing a place which is a
    composition of CAR+CDR operations, such as (SHIFTF (CADR X) (ELT V 0)),
    do not access subforms more than once. (lp#1450968)
  * bug fix: short form of DEFSETF no longer allows trailing junk.
  * bug fix: DEFINE-MODIFY-MACRO respects the provisions of CLHS 5.1.3
    regarding argument evaluation order. (lp#1452539)
  * bug fix: POP works as specified in CLHS if the setter for its
    argument has a side-effect on the existing CAR value. (lp#1454021)
  * bug fix: Reading "#()" with a positive numeric argument signals a
    reader error. As specified, reading "#1()" has undefined consequences,
    so correct portable code should be indifferent to this. (lp#1252100)

sbcl-1.2.11 released

Hi,

I released sbcl-1.2.11 yesterday, but circumstances prevented me from
sending an announcement to this list until now.  Apart from the release
notes listed below, I'd like to mention that some months ago Josh
Elasser provided experimental threading support for OpenBSD on x86-64
(and even more experimental on x86 and ppc).

Additionally, with the release of Debian Jessie, I would like to upgrade
my build environment to the new "oldstable" (wheezy).  This will mean
that the sbcl binaries that I build will be linked against a newer
version of glibc than they have been until now: 2.13 (rather than
2.11).  If this will cause problems for anyone, I can delay: please just
let me know.

Best wishes,

Christophe

changes in sbcl-1.2.11 relative to sbcl-1.2.10:
  * enhancement: SET-PPRINT-DISPATCH will warn when given an expression in
    which any part is unrecognizable as a legal type-specifier.
    The dispatch table will be altered, but the new entry is disabled.
    Subsequent type-defining forms will cause pprint-dispatch tables to
    re-examine whether any disabled entries should be enabled. (lp#1429520)
  * enhancement: Loading code containing calls to a deprecated function will,
    under most circumstances, signal warnings similar to compiling such code.
    The usual caveat holds about not detecting calls through a computed name,
    as in (funcall (intern "DEPRECATED-FUN" "SB-EXT")).
  * enhancement: (SB-EXT:COMPILE-FILE-LINE) is a new macro that expands

sbcl-1.2.10 released

Dear all,

SBCL 1.2.10 has been released; the release notes are appended to this
message.  One thing that is not mentioned in the release notes, but
which has been exercising developers recently, is a warning for the near
future: some interfaces which are currently in "early" deprecation
status (and so are emitting style-warnings at compilation-time) will in
the next release cycle or two start emitting full warnings, either at
compilation time or at load time.  Particular interfaces signalling
warnings causing problems to some users include: SB-EXT:QUIT, and the
SB-THREAD:SPINLOCK API.  If anyone is using those, now is the time to
update to SB-EXT:EXIT and SB-THREAD:MUTEX respectively.  (See also the
"Deprecated Interfaces" chapter in the manual).

Best wishes,

Christophe

changes in sbcl-1.2.10 relative to sbcl-1.2.9:
  * minor incompatible change: all SOCKINT::WIN32-* functions have been
    deprecated with EARLY deprecation state
  * minor incompatible change: performing introspection via the system-internal
    SB-INT:INFO function could expose that :TYPE :TRANSLATOR is not necessarily
    a function, as it always was before. (Affects swank-fancy-inspector)
  * enhancement: The value of SXHASH on bit-vectors of length equal to the
    word size now depends on the vector's contents instead of being constant;
    its value on bit-vectors of length divisible by the word size now depends
    also on the contents of the vector's last word.
  * bug-fix: sb-bsd-sockets on win32 uses proper C function declarations.

sbcl-1.2.9 released

Dear all,

I've just released sbcl-1.2.9, and uploaded sources and an x86-64/linux
binary to Sourceforge.  The release notes are appended to this message.

Best wishes,

Christophe

changes in sbcl-1.2.9 relative to sbcl-1.2.8:
  * minor incompatible change and bug fix: unboxed numeric constants
    on x86oids are arranged in memory differently, and the disassembler
    does not show them separately in DISASSEMBLE, but does
    if DISASSEMBLE-CODE-COMPONENT is used. (lp#1421987)
  * optimization: The compiler's treatment of type specifiers makes
    it slightly faster and more memory-efficient. Portable code
    should be indifferent to this change, however, users of
    SB-INTROSPECT:FUNCTION-TYPE might notice that (MEMBER T NIL)
    and (MEMBER NIL T) are both internally collapsed to the former,
    so that the latter can never be obtained as part of an FTYPE.
  * optimization: a TYPEP call in which the second argument is not a
    QUOTE form but nevertheless recognized as a compile-time constant
    might open-code the test. One scenario for this involves backquote,
    such as (TYPEP x `(my-type ,some-arg)). Code which relied upon
    deferring until runtime should declare (NOTINLINE TYPEP).
    [Due to the sematic constraints of DEFTYPE etc in in CLHS 3.2.2.3,
    code requiring delayed evaluation could be unportable though.]
  * enhancement: unused variables at the top-level are now reported.
    (lp#492200)
  * bug fix: DEFCLASS handles cyclic {super,meta}class relations better
