(Thanks to mon_key; launchpad + bug lp#518696) + * bug fix: fix compilation on chenygc platforms. Thanks to Larry Valkama and + Bruce O'Neel. + * bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a deadline twice + in a row even though a handler defered the deadline long into the + future. (lp#512914) + * bug fix: a deadline handler was run without interrupts enabled for a + deadline signaled within SB-THREAD:CONDITION-WAIT. That could result + in infinitely spinning, non-killable threads. + * bug fix: backtrace from internal-errors on x86-64 os x was truncated + before reaching the erring stack frame. + +changes in sbcl-1.0.35 relative to sbcl-1.0.34: + * optimization: ROUND with a single single-float or double-float argument + is properly inlined when possible. + * optimization: Slightly better code is generated for integer<->float + conversions and for single-float<->double-float conversions on x86-64. + * optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient + code for 32-bit and 64-bit rotations on x86-64. + * bug fix: The install script changes the ownership of directories as well + as files for contrib modules using asdf. (thanks to Eugene Ossintsev; + launchpad bug lp#508485) + * bug fix: TRUNCATE with a single single-float or double-float argument is + properly inlined when possible. (launchpad bug lp#489388) + * bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE + no longer causes a compiler error on x86 and ppc. + * bug fix: GET-MACRO-CHARACTER bogusly computed its second return value + always relative to *READTABLE* rather than the passed argument. + +changes in sbcl-1.0.34 relative to sbcl-1.0.33: + * minor incompatible change: threading support is now enabled by default + on x86[-64] Linux. + * enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most + builtin types. + * enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN) + are now caught and reported just like errors during macroexpansion. + * enhancement: SB-POSIX now provides access to tcdrain(), tcflow(), + tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James) + * enhancement: ASDF systems can now depends on SB-QUEUE. + * fixes and improvements related to Unicode and external formats: + ** bug fix: error handling and restart usage in the ucs-2 external format + has been improved. + ** there is now an implementation of the ucs-4 external format. + ** the utf-16 and utf-32 external formats are supported. + * bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings + in the environment. setenv() and unsetenv() are also provided. (reported by + Fare Rideau; launchpad bug lp#460455) + * bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style + loading. This ensures sensible errors for .FASL files from other + implementations on case-insensitive filesystems. (reported by Willem + Broekema; launchpad bug lp#489417) + * bug fix: #p"\\\\" can now be read without error on Win32. (reported by + Willem Broekema; launchpad bug lp#489698). + * bug fix: some minor code rearrangements to reenable warning-free building + from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104) + * bug fix: PRINT-OBJECT for clos instances respects the right margin when + pretty printing + * bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by + Attila Lendvai) + +changes in sbcl-1.0.33 relative to sbcl-1.0.32: + * new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent) + * improvement: support O_LARGEFILE access to files larger than 2GB on + x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080) + * new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of + definitions for methods specializing on the passed class itself. + * new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of + definitions for methods specializing on the passed class itself, or on + subclasses of it. + * new build flag: :sb-xref-for-internals; SBCL will collect xref information + about itself during the build (e.g. for M-? in Slime), if this flag is + enabled in customize-target-features.lisp. This will increase the core + size by about 5-6mb, though, so it's mostly interesting to SBCL + developers. + * new feature: various GENCGC tuning parameters have been experimentally + documented and exported from SB-EXT. See documentation for details. + * fixes and improvements related to Unicode and external formats: + ** the Unicode character database has been upgraded to the + Unicode 5.2 standard, giving names and properties to a number of new + characters, and providing a few extra characters with case + transformations. + ** improvement: restarts for providing replacement input/output on coding + errors for fd-stream external formats. + ** improvement: where : is a keyword corresponding to an + external format the system supports, it is now possible to specify + (: :replacement ) as an external format which will + automatically substitute on encoding or decoding errors for + streams and for STRING-TO-OCTETS and its inverse. (launchpad bug + lp#317072) + ** improvement: the file streams underlying the standard streams (such as + *STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format + which uses the replacement mechanism to handle encoding errors, + preventing various infinite error chains and unrecoverable I/O + confusion. + ** minor incompatible change: the utf-8 external format now correctly + refuses to encode Lisp characters in the surrogate range (char-codes + between #xd800 and #xdfff). + ** fix a typo preventing conversion of strings into octet vectors + in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug + lp#471689) + ** fix a bug in the octet multibyte handling of decoding errors and the + USE-VALUE restart. (launchpad bug lp#314939) + ** fix the bug underlying the expected failure in the FORCE-END-OF-FILE + restart on fd-stream decoding errors. + ** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the + error is near the end of file. + ** fix a double-error case in unibyte octet conversions, when the first + use of USE-VALUE is ignored. + ** fix bugs in handling of undefined code points in unibyte encodings. + ** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent + streams after an UNREAD-CHAR. + * enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the + object is allocated in a boxed region of dynamic space. + * enhancement: SB-POSIX:FORK now signals an error if an attempt to + fork with multiple Lisp threads running is made, instead of going + ahead with unpredictable consequences. (reported by Leslie Polzer) + * bug fix: uses of slot accessors on specialized method parameters within + the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type + error while finalizing the class. This fix may cause classes with slot + accessors to be finalized later than previously. (reported by Lars Rune + Nøstdal; launchpad bug lp#473699) + * bug fix: restore buildability on the MIPS platform. (regression from + 1.0.30.38, reported by Samium Gromoff) + * bug fix: inspecting closures is less likely to fail with a type error. + * bug fix: no timer starvation when setting the system clock back. + (launchpad bug lp#460283) + * bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the + standard pprint dispatch table as specified by CLHS. + * bug fix: give CLISP a hint about a type declaration to enable it to build + the cross-compiler without warnings. (thanks to Josh Elasser; launchpad + bug lp#396597) + * bug fix: correctly dump literal objects in defaulting forms of arglists. + (reported by Attila Lendvai; launchpad bug lp#310132) + * bug fix: distinguish in type specifiers between arrays that might be + complex and arrays that are definitely complex. (launchpad bug lp#309129) + * bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD + type. (reported by Levente Mészáros; launchpad bug lp#485972) + * bug fix: setting the value of a symbol-macro within a method in the + presence of type declarations works properly again. (reported by Iban + Hatchondo; launchpad bug lp#485019) + +changes in sbcl-1.0.32 relative to sbcl-1.0.31: + * optimization: faster FIND and POSITION on strings of unknown element type + in high SPEED policies. (thanks to Karol Swietlicki) + * optimization: faster CONCATENATE 'STRING in low SPEED policies (reported + by David Vázquez) + * improvement: better error signalling for bogus parameter specializer names + in DEFMETHOD forms (reported by Pluijzer) + * bug fix: DELETE-FILE once again works on logical pathnames (regression + since 1.0.30.49) + * bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified + incorrectly. + * bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS + removes previous default initargs (reported by Lars Rune Nøstdal and + Samium Gromoff) + * bug fix: correct WHO-CALLS information for inlined lambdas with complex + lambda-lists. (reported by Peter Seibel) + * bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work + correctly when starting from an executable core without saved runtime + options (reported by Faré Rideau, thanks to Zach Beane) + * bug fix: (SETF SLOT-VALUE) signalled a warning which should have been + an optimization note instead. (reported by Martin Cracauer) + * bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin) + * bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a + new process group if it doesn't need to share stdin with the sbcl + process. (thanks to Leslie Polzer) + * bug fix: SATISFIES could be misoptimized to refer to a local function. + (reported by Stanislaw Halik) + changes in sbcl-1.0.31 relative to sbcl-1.0.30: * improvement: stack allocation is should now be possible in all nested inlining cases: failure to stack allocate when equivalent code is manually
