sbcl-1.3.1
38b330fb · ·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 * bug fix: NTH-VALUE does not cause stack overflow.

sbcl-1.3.0
dab9ef7a · ·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 termios (verified on Linux, still known not to work on FreeBSD and NetBSD, very probably others). (partial fix for lp#1500951) -

02b0f4b2 · ·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.

sbcl-1.2.15
4bc676e3 · ·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.

sbcl-1.2.14
abbbd362 · ·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-1.2.13
e9a09536 · ·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. -

6f689c23 · ·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)
