+changes in sbcl-0.9.2 relative to sbcl-0.9.1:
+ * numerous signal handling fixes to increase stability
+ * bug fix: interrupt-thread restores the eflags register on x86
+ * minor incompatible change: we now correctly canonize default
+ initargs, making them be a list of (INITARG INITFORM INITFUNCTION)
+ as per the MOP, rather than the historical (INITARG INITFUNCTION
+ INITFORM). (reported by Bruno Haible)
+ * new feature: WITH-COMPILATION-UNIT now accepts a non-standard
+ :SOURCE-PLIST option. See (DOCUMENTATION #'WITH-COMPILATION-UNIT T)
+ for more information.
+ * TRUENAME and PROBE-FILE now correctly resolve symlinks even if the
+ pathname is a directory pathname.
+ * SB-SPROF now works (more) reliably on non-GENCGC platforms.
+ * fixed some lockups due to gc/thread interaction
+ * dynamic space size on PPC has been increased to 768Mb. (thanks to
+ Cyrus Harmon)
+ * SB-MOP:ENSURE-CLASS-USING-CLASS now accepts a class as the
+ :METACLASS argument in addition to a class name. (reported by
+ Bruno Haible for CMUCL, patch for CMUCL by Gerd Moellman)
+ * bug fix: sbcl runtime can now be compiled with gcc4 (thanks to
+ Sascha Wilde)
+ * bug fix: more cleanups to the floating point exception handling on
+ x86-64 (thanks to James Knight)
+ * optimization: improved the MIPS versions of generic (in the
+ generic sense) arithmetic routines. (thanks to Thiemo Seufer)
+ * contrib improvement: it's harder to cause SOCKET-CLOSE to close()
+ the wrong file descriptor; implementation of SOCKET-OPEN-P.
+ (thanks to Tony Martinez)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** invalid dotted lists no longer raise a read error when
+ *READ-SUPPRESS* is T
+ ** signal an error if a symbol that names a declaration is used
+ as the name of a type, or vice versa
+ ** allow using the (declare (typespec var*)) abbreviation for
+ (declare (type typespec var*)) with all type specifiers
+ ** circularity detection works properly with PPRINT-LOGICAL-BLOCK
+ ** always return NIL from PPRINT-POP when OBJECT is NIL
+ ** don't signal errors when pretty-printing malformed LABELS,
+ FLET or MACROLET forms
+
+changes in sbcl-0.9.1 relative to sbcl-0.9.0:
+ * fixed cross-compiler leakages that prevented building a 32-bit
+ target with a 64-bit host compiler.
+ * fixed a bug in CLOSE :ABORT T: no longer attempts to remove files
+ opened with :IF-EXISTS :OVERWRITE.
+ * fixed bug 281: error for an invalid qualifier in a short-form method
+ combination method is not signalled until the faulty method is called.
+ * bug fix: iteration variable type inferrer failed to deal with open
+ intervals. (reported by Alan Shields)
+ * bug fix: dynamically loading (via LOAD-SHARED-OBJECT or similar)
+ "frameworks" on Mac OS X no longer causes an EXC_BAD_ACCESS if two
+ or more runtime options were provided to the sbcl binary.
+ * compiled code is not steppable if COMPILATION-SPEED >= DEBUG.
+ * contrib improvement: implement SB-POSIX:MKSTEMP (Yannick Gingras)
+ * optimization: there's now a fast-path for fixnum arguments in the
+ generic subtraction routines on x86/x86-64. (Thanks to Lutz Euler)
+ * optimization: the code generated on x86-64 is more compact thanks
+ to not outputting unneccessary prefix bytes. (Thanks to Lutz Euler)
+ * bug fix: floating-point exception handling now partly works on
+ x86-64. (Thanks to James Knight)
+ * improvement to the MIPS backend from Thiemo Seufer: C-style
+ 64-bit long long arguments and return values to alien functions
+ are now supported.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** the type-error signalled from WARN has a filled-in DATUM slot.
+ ** the type-error required when a stream is not associated with
+ a file has the stream as its datum.
+ ** type-errors on single-floats on x86-64 no longer have
+ :INVALID-OBJECT as the datum
+ ** the type-errors signalled for invalid function names now have
+ a correct expected type
+ ** (SETF (DOCUMENTATION ... 'STRUCTURE)) no longer signals an error
+ for structures defined with a :TYPE. Documentation strings for
+ typed structures are no longer immediately discarded
+ ** FILE-STRING-LENGTH and STREAM-EXTERNAL-FORMAT now work on
+ broadcast streams and synonym streams. FILE-LENGTH now also works
+ on broadcast streams.
+
+changes in sbcl-0.9.0 relative to sbcl-0.8.21:
* incompatible change: the --noprogrammer option, deprecated since
version 0.7.5, has been removed. Please use the equivalent
--disable-debugger option instead.
- * Null lexical environments are now printed as #<NULL-LEXENV>,
+ * incompatible change: finalizers and *AFTER-GC-HOOKS* are now run with
+ interrupts enabled.
+ * incompatible change: support for *BEFORE-GC-HOOKS* (that have been
+ inoperational for a while now) has been completely removed.
+ * null lexical environments are now printed as #<NULL-LEXENV>,
significantly reducing the amount of clutter in typical backtraces.
+ * documentation on weak pointers, finalization, and after GC hooks
+ has been added to the manual.
* optimization: REPLACE on declared (UNSIGNED-BYTE 8) vectors, as well
as other specialized array types, is much faster. SUBSEQ and
COPY-SEQ on such arrays have also been sped up.
+ * optimization: EQL is now more efficient when at least other argument
+ is known to be of type (OR FIXNUM (NOT NUMBER)).
+ * fixed bug: the runtime is now less vulnerable to changes in the
+ size of the SBCL object on OS X, and virtual memory is reserved for
+ all spaces that need to be at a fixed address.
+ * fixed bug: finalizers are now thread-safe. (thanks to Gabor Mellis)
+ * fixed bug: finalizers and after GC hooks that cause consing are now
+ safe.
* fixed bug: compiler error messages and summaries are now printed to
*ERROR-OUTPUT*, not *STANDARD-OUTPUT*.
* fixed inference of the upper bound of an iteration variable.
(reported by Rajat Datta).
+ * fixed bug 211e: calling local functions with duplicated constant
+ keyword argument no longer causes a bogus style warning about an
+ unused variable.
+ * fixed bug 305: INLINE/NOTINLINE declaration no longer causes local
+ ftype declaration to be disregarded. (reported by Dave Roberts)
* fixed bug 373: caused by erronous compilation of references to alien
variables in the runtime on ppc/darwin.
* fixed bug 376: CONJUGATE type deriver.
fixed. (thanks to Bruno Haible)
* improvements to the MIPS runtime code for increased stability.
(thanks to Thiemo Seufer)
+ * increased the maximimum compact environment size to allow
+ purify on images with large amounts of functions. (thanks to Cyrus Harmon)
+ * partial workaround for bug 135: don't name the function we're
+ calling for hairy cases of EVAL, so as not to accumulate one environment
+ entry per call to EVAL. (reported by Kevin Reid)
+ * improvements to the x86-64 disassembler. (thanks to Lutz Euler)
+ * optimization: type testing for non-vector arrays should be faster.
+ * fixed TRACE :ENCAPSULATE NIL, added support for :ENCAPSULATE NIL
+ on x86-64
+ * bug fix: setting 31st element of a bit vector to zero did not work
+ on Alpha-32.
+ * bug fix: redefining a class definition which failed due to a
+ previous accessor / function clash now works (but see BUGS entry
+ #380 for more problems in this area). (thanks to Zach Beane)
+ * the long form of DEFINE-METHOD-COMBINATION disables method group
+ checking when given a single method group with pattern *. (thanks
+ to Wendall Marvel)
+ * on x86 compiler supports stack allocation of results of simple
+ calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT.
+ * support for building and running on Mac OS X 10.4 "Tiger" has been added
+ ** Binaries built on Tiger will not run on 10.2 "Jaguar" currently
* fixed some bugs related to Unicode integration:
** the restarts for recovering from input and output encoding
errors only appear when there is in fact such an error to
handle.
- * increased the maximimum compact environment size to allow
- purify on images with large amounts of functions. (thanks to Cyrus Harmon)
- * improvements to the x86-64 disassembler. (thanks to Lutz Euler)
* fixed some bugs revealed by Paul Dietz' test suite:
** MISC.549 and similar: late transformation of unsafe type
assertions into derived types caused unexpected code
** accessing double-floats stored on the stack now works on x86-64.
** debugger internals could sometimes create invalid lispobjs,
resulting in GC crashes.
+ ** MISC.548: type check weakening can convert required type into
+ optional.
+ ** initialization forms for bindings are not in scope of free special
+ declarations.
