sbcl Debian release 2:1.2.15-2

sbcl Debian release 2:1.2.15-1

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 Debian release 2:1.2.14-1

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
    after a call of ADJUST-ARRAY. (lp#1333731)
  * bug fix: Dynamic-extent allocation with a loop between allocating a value
    and the start of its environment no longer discards the allocated data
    when the loop is taken. (lp#1472785)
  * bug fix: Variable-reference elimination no longer generates incorrect code
    under certain circumstances. (lp#1446891)
  * bug fix: variables with EQL types are no longer treated as constants by
    VOPs, which caused problems with closures being allocated for such
    variables, but they remained unused. (lp#1390149)
  * bug fix: Windows installer generates registry key name
    correctly. (lp#1476447)

sbcl Debian release 2:1.2.13-1

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
    due to faulty introspection of the lambda list of a closure.
  * bug fix: out of line MAP/MAP-INTO check that the results produced by the
    function are of the matching sequence type. (lp#1459581)
  * bug fix: pretty-printing of '(LET `((,X ,Y)) :B) is handled correctly.

sbcl Debian release 2:1.2.12-1

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)
  * bug fix: Malformed reader conditionals such as "(#-no-such-feature)"
    and "(#+sbcl)" no longer parse as NIL. (lp#1454400)

sbcl Debian release 2:1.2.11-2

sbcl Debian release 2:1.2.11-1

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
    to a constant (VALUES integer integer) indicating the source line/column
    from which it was read, intended for logging Lisp runtime errors in
    a style similar to that afforded by the C preprocessor __LINE__ macro.
    Similarly (SB-EXT:COMPILE-FILE-POSITION) returns a position in characters.
  * enhancement: improved source locations for VOPs, alien types and
    declarations.
  * bug fix: functions in :FINAL deprecation have the correct docstring.
    No visible change, as no such functions presently exist. (lp#1439151)
  * bug fix: (SETF (FDEFINITION this) (FDEFINITION OTHER)) signals an error
    if OTHER names either a macro or special-operator. (lp#1439921)

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.
    (lp#1426667)
  * bug fix: A new dead code elimination phase removes dead code loops
    that confuse stack analysis. (lp#1255782, lp#308914)
  * bug fix: A toplevel form which was simple enough to bypass the main
    compiler in COMPILE-FILE, and which contained an empty SETQ or PROGN
    would produce an invalid fasl file. (lp#1427050)
  * bug fix: The compiler no longer signals an internal error when
    encountering invalid FUNCTION forms like (function 1)
  * bug fix: express proper dependencies in the ASDF contrib, to support
    systems where make runs in parallel.  (lp#1434768; thanks to Nikhil
    Benesch)

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
    (lp#1418883)
  * bug fix: compiler no longer signals an error when compiling certain
    function calls. (lp#1416704, lp#404441, lp#1417822, lp#1234919)
  * bug fix: compiler doesn't stumble on a LOGIOR transform. (lp#1389433)
  * bug fix: more robust debugger and backtraces. (lp#1413850, lp#1099500,
    lp#1412881, lp#945261, lp#1419205, lp#1409402)
  * bug fix: files larger than 4GB can now be compiled.
  * bug fix: x86 truncated results from 64-bit foreign functions to 32 bits.
  * bug fix: file-position didn't work on large files on win32. (lp#1271545)
  * bug fix: callbacks from foreign threads can work without enabling
    sb-safepoint.
  * bug fix: sb-introspect:function-lambda-list works properly on interpeted
    macros. (lp#1387404)
  * bug fix: ADJUST-ARRAY properly handles non-adjustable arrays. (lp#886418)
  * bug fix: compiler no longer fails to dump a multidimensional array
    constant involving a circular reference to itself
  * bug fix: conditional and nested DX allocation no longer confuse the
    compiler in STACK analysis. (lp#1044465)
  * bug fix: sb-rotate-byte constant folding bug fixed. (lp#1423682)

sbcl Debian release 2:1.2.4-2

changes in sbcl-1.2.8 relative to sbcl-1.2.7:
  * enhancement: better error and warning messages. (lp#1314767, lp#736383)
  * enhancement: backtrace for invalid argument count produces the exact
    supplied arguments including the extra ones, on x86, x86-64 and ARM.
  * enhancement: a STYLE-WARNING is signaled for DEFSTRUCT accessors which
    are used before the structure is defined; similarly for the predicate.
  * optimization: FORMAT NIL with only ~a and string arguments is transformed
    into CONCATENATE.
  * optimization: POSITION and FIND when inlined into code that is compiled
    with qualities of safety < 2 and speed > space will no longer signal
    an error on circular lists, but will potentially loop forever if given
    no :END constraint. As was always the case, calls that are not inlined
    are safe regardless of lexical policy.
  * bug fix: CLOS methods compiled with (OPTIMIZE (DEBUG 0))
    no longer cause debugger failure when printing a backtrace
  * bug fix: more resilience to deleted code. (lp#1308328, lp#1390544)
  * bug fix: the CLHS example of MAKE-LOAD-FORM involving TREE-WITH-PARENT
    did not work, and now it does.

changes in sbcl-1.2.7 relative to sbcl-1.2.6:
  * optimization: returning constant values refers to preboxed constants
    more reliably. (lp#1398785)
  * enhancement: a STYLE-WARNING is produced if a compiler-macro is defined
    for a function after at least one ordinary (not inlined) call to that
    function was compiled, indicating a likely compilation order problem.
    Likewise a warning ensues if a call is compiled to a function
    that is subsequently proclaimed INLINE.
  * enhancement: always lose() when something goes wrong while saving a core
    (instead of just printing an error on stderr in some situations).
  * enhancement: frames in the debugger are now restartable by default.
  * bug fix: restore error handling on Windows x86.
  * bug fix: MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
    at compile-time when possible. (lp#330299)
  * bug fix: parsing of malformed type specifiers no longer results
    in a memory-fault-error.
  * bug fix: LOOP properly destructures nested lists in WITH.
  * bug fix: MACROEXPANDing the redefinition of an alien structure type no
    longer signals the wrong error.
  * bug fix: PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).

changes in sbcl-1.2.7 relative to sbcl-1.2.6:
  * optimization: returning constant values refers to preboxed constants
    more reliably. (lp#1398785)
  * enhancement: a STYLE-WARNING is produced if a compiler-macro is defined
    for a function after at least one ordinary (not inlined) call to that
    function was compiled, indicating a likely compilation order problem.
    Likewise a warning ensues if a call is compiled to a function
    that is subsequently proclaimed INLINE.
  * enhancement: always lose() when something goes wrong while saving a core
    (instead of just printing an error on stderr in some situations).
  * enhancement: frames in the debugger are now restartable by default.
  * bug fix: restore error handling on Windows x86.
  * bug fix: MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
    at compile-time when possible. (lp#330299)
  * bug fix: parsing of malformed type specifiers no longer results
    in a memory-fault-error.
  * bug fix: LOOP properly destructures nested lists in WITH.
  * bug fix: MACROEXPANDing the redefinition of an alien structure type no
    longer signals the wrong error.
  * bug fix: PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).

changes in sbcl-1.2.6 relative to sbcl-1.2.5:
  * enhancement: SERVE-EVENTS uses the poll() system call in lieu of
    select() if the OS has the former. Previously poll() was used
    only if waiting on exactly one file descriptor.
  * enhancement: efficiency of access to untagged structure slots is improved
    on x86-64, and the order of slots in memory is exactly as specified by
    defstruct, simplifying use of structures as arguments to foreign calls.
  * bug fix: SB-DEBUG:ARG now works in all TRACE options which evaluate forms.
   (lp#1357826)
  * bug fix: GC memory corruption during internal memory handling.
  * bug fix: duplicate effective-slot-definition objects as compared
    by EQ on name could be present in CLASS-SLOTS of a class whose
    metaclass was structure-class or condition-class. (lp#1049423)
  * bug fix: HANDLER-BIND with empty bindings works again; regression in
    1.2.5. (lp#1388707)
  * bug fix: ATOMIC-INCF works on structure slots in interpreted code.
    (lp#1381867)
  * bug fix: MAKE-ARRAY properly handles character types like (eql #\a) and
    (member #\a #\c). (lp#1392068)
  * bug fix: READ sometimes accidentally preserved a whitespace character
    after a token when it should not have. (lp#327790)

changes in sbcl-1.2.5 relative to sbcl-1.2.4:
  * enhancement: sb-bsd-sockets now has basic support for IPv6
  * enhancement: An sb-unicode package has been added, containing
    many functions related to handling Unicode text
  * enhancement: The reader now normalizes symbols to Normalization
    Form KC (NFKC). This behavior can be disabled with
    SB-EXT:READTABLE-NORMALIZATION
  * enhancement: a style-warning is signaled if OPTIMIZE declarations
    multiply specify a quality with differing values. (lp#310267)
  * bug fix: conservatively pointed to pages wipe out unused dwords so
    that they cannot act as false roots in turn.
  * bug fix: the walker's handling of lexical variable and symbol-macro
    bindings is improved (lp#375326, lp#1368305)
  * bug fix: HANDLER-{BIND,CASE} no longer drop into ldb when a clause
    contains an undefined condition type; regression in 1.1.19 (lp#1378939)
  * bug fix: in interpreted code, inequality predicates did not type-check
    arguments that weren't examined, and a 1-argument use of MIN or MAX
    accepted a complex number. (lp#1373702)
  * bug fix: APROPOS and APROPOS-LIST handle inherited symbols correctly.
    (lp#1364413, thanks to Zach Beane)
