+changes relative to sbcl-1.0.42
+ * bug fix: bogus type errors from (AREF A (+ POSITIVE-OFFSET N)) under
+ certain circumstances when N was negative but (+ POSITIVE-OFFSET N)
+ was non-negative. (lp#622958)

+
+changes in sbcl-1.0.42 relative to sbcl-1.0.41
+ * build changes
+ ** Cross-compilation host is now specified to make.sh using
+ command-line argument --xc-host=<command> instead of a positional
+ argument. (thanks to Daniel Herring)
+ ** Install location can be specified to make.sh using command-line
+ argument --prefix=<path>. (lp#550889s, thanks to Daniel Herring)
+ * optimization: The default implementation of
+ COMPUTE-DISCRIMINATING-FUNCTION does much less wasted work.
+ * enhancement: Explicit memory barrier operations are now available for use
+ by multithreaded code. See documentation for details.
+ * enhancement: Experimental support for threading on Linux/PPC.
+ * bug fix: RENAME-PACKAGE returns the package. (Thanks to Eric Marsden)

+ (lp#612998, reported by Phil Hargett; patch from Jim Wise)
+
+changes in sbcl-1.0.41 relative to sbcl-1.0.40:
+ * optimization: validity of observed keyword initargs to MAKE-INSTANCE is
+ cached, leading to many fewer expensive calls to
+ COMPUTE-APPLICABLE-METHODS.
+ * optimization: in the (unoptimized) general method for MAKE-INSTANCE on a
+ CLASS argument, search for and call an appropriate optimized ctor function
+ if it exists.
+ * bug fix: WRITE always returns the correct value.
+
+changes in sbcl-1.0.40 relative to sbcl-1.0.39:
+ * bug fix: readdir now works on :inode64 darwin builds (lp#592897)
+ * bug fix: Name conflicts between symbols passed as arguments to a single
+ call to IMPORT no longer add multiple symbols with the same name to the
+ package (detectable via DO-SYMBOLS).

+ (lp#533470).
+ * bug fix: TRACE :ENCAPSULATE NIL now works on ppc/linux.
+
+changes in sbcl-1.0.39 relative to sbcl-1.0.38:
+ * bug fix: Backtrace from undefined function on x86 and x86-64 now show
+ the calling frame.
+ * bug fix: linkage-table entries on PPC now no longer overflow their
+ space allocation (potentially causing crashes if they are written out
+ of order).
+ * bug fix: Scrub control stack after scavenging in gencgc on non-x86oid
+ platforms, preventing the GC from seeing stale pointers on the control
+ stack in subsequent GCs (which would, and does, break invariants).

+ * bug fix: Literal characters with code points greater than about 32767
+ now work on PPC UNICODE builds.
+ * bug fix: Any noise left by SSE operations (sqrt and conversions) in the
+ high order bits are explicitly cleared out. In some contrived situations,

+
+changes in sbcl-1.0.38 relative to sbcl-1.0.37:
+ * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
+ like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
+ * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
+ contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
+ * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
+ SB-THREAD:GRAB-MUTEX.
+ * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
+ contain additional data structures and tools for concurrent programming;
+ at the moment it contains a lock-free queue, and a lock-free mailbox
+ implementation.
+ * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
+ GET-MUTEX but takes &key rather than &optional parameters. Also added
+ :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
+ BSD.
+ * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
+ SB-THREAD:WAIT-ON-SEMAPHORE.

+ now bivalent.
+ * enhancement: errors from NO-APPLICABLE-METHOD and
+ NO-PRIMARY-METHOD now have a RETRY restart available to retry the
+ generic function call.
+ * enhancement: SB-BSD-SOCKET improvements
+ ** sockets and socket streams now have a more informative printed
+ representation based on the corresponding SOCKET-NAME and
+ SOCKET-PEERNAME.
+ ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
+ (lp#540413)
+ ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
+ CL:CLOSE when appropriate, and no longer disassociates the stream
+ from the socket if close failed. (lp#543951)
+ * improvements to the instrumenting profiler
+ ** new feature: report per-function GC overhead. (thanks to John Fremlin)
+ ** optimization: counters no longer use locks for the overflow mode.
+ ** bug fix: whenever a profiling counter wrapped into overflow mode, it
+ incurred an off-by-one miscount.
+ * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
+ * enhancement: improved DEFMETHOD pretty-printing.
+ * enhancement: perform range reduction when arguments are too large for
+ x87's transcendentals (instead of returning 0). (lp#327192)
+ * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
+ some of CL-PPCRE's macros. (lp#570079)
+ * enhancement: our machine code is slightly less hostile to valgrind on
+ x86-64.
+ * enhancement: up-to-date versions of NetBSD-current are supported. (Thanks
+ to Robert Swindells and Aleksej Saushev)
+ * bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
+ * bug fix: a rare case of startup-time page table corruption.
+ * bug fix: a semaphore with multiple waiters and some of them unwinding due
+ to timeouts could be left in an inconsistent state.
+ * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
+ * bug fix: misoptimization of multiplication by one in
+ (SB-C::FLOAT-ACCURACY 0) policies.
+ * bug fix: miscounts in SB-PROFILE.
+ * bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
+ CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
+ condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
+ up itself" (March 2010) for further details.
+ * bug fix: allow forward FIND and POSITION on lists to elide checking :END
+ against length of the list if the element is found before the specified
+ END is reached. (thanks to Alec Berryman, lp#554385)
+ * bug fix: errors signalled during package graph modification no longer
+ block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
+ * bug fix: SB-POSIX build was broken when SBCL was compiled without the
+ :SB-DOC feature. (lp#552564)
+ * bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
+ * bug fix: more robust runtime executable path detection. (lp#375549)

+ * bug fix: Transforms for TRUNCATE don't die when the result is completely
+ ignored anymore.
+ * bug fix: Maybe restore buildability on Alpha.
+ * bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
+ (lp#569404)
+ * bug fix: RANDOM-STATE can be printed readably again.
+ * bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
+ * bug fix: Using EQL with non-constant values of constant type (e.g. EQL
+ types) could result in type mismatches during compilation.
+
+changes in sbcl-1.0.37 relative to sbcl-1.0.36:
+ * enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
+ stack frame thrown from.
+ * enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to
+ compiler optimization qualities inside dynamic extent of its body.
+ * enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load
+ translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
+ Weber)
+ * optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
+ constraint propgation, allowing better compilation eg. when used to
+ access structures with WITH-SLOTS. (lp#520366)
+ * optimization: the compiler is now more aware of the type of the underlying
+ storage vector for multidimensional simple arrays resulting in better code
+ for accessing such arrays.

+ * bug fix: Breakpoints now work when using ud2 instead of int3 as trap
+ instruction (tested on x86oid linux with ud2-breakpoints).
+ * bug fix: slam.sh now works on win32.
+ * bug fix: better differences of numeric types. (lp#309124)
+ * bug fix: arrays declared intersection and union types can have their

+ * bug fix: SB-SPROF allocation profiling for all threads failed to profile
+ threads started during profiling. (lp#472499)
+ * bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
+ (lp#535658)
+ * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
+ SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)
+ * bug fix: Comma inside a backquoted array or structure resulted in nonsense
+ values instead of signaling an error. (lp#309093)

+ * bug fix: more accurate WHO-MACROEXPANDS information; point into rather
+ than just at toplevel form.
+
+changes in sbcl-1.0.36 relative to sbcl-1.0.35:
+ * new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
+ SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND counterparts
+ but work on type specifiers.
+ * new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a symbol is known
+ to name a type specifier.
+ * new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a given type
+ specifier is valid where "valid" basically means "would be accepted as
+ second argument of TYPEP".
+ * new feature: SB-INTROSPECT:FUNCTION-TYPE takes a function-designator and

+ PRNG where possible. (Thanks to Fare Rideau; launchpad bug lp#310116)
+ * bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set the

+ * 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

+ 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.

+ 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).

+ 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 :<encoding> is a keyword corresponding to an
+ external format the system supports, it is now possible to specify
+ (:<encoding> :replacement <character>) as an external format which will
+ automatically substitute <character> 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:

+ in DEFMETHOD forms (reported by Pluijzer)
+ * bug fix: DELETE-FILE once again works on logical pathnames (regression
+ since 1.0.30.49)

+ removes previous default initargs (reported by Lars Rune Nøstdal and
+ Samium Gromoff)

+ 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
+ open coded is now considered a bug.

+ * optimization: multiplication of single- and double-floats floats by
+ constant two has been optimized.
+ * optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when

+ * optimization: unused vector creation can now be optimized away.
+ * improvement: ASDF systems can now depends on SB-INTROSPECT.
+ * improvement: a STYLE-WARNING is signalled when a generic function

+ * bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
+ leading to possible attempts to delete the same file twice. See docstring
+ on DELETE-FILE for details. (reported by John Fremlin)
+ * bug fix: DELETE-FILE once again deletes the file named by the pathname
+ designator argument, rather than its truename. (reported by Luis
+ Oliveira)
+ * bug fix: the low-level debugger had 32-bit assumptions and was missing
+ information about some array types. (thanks to Luis Oliveira)
+ * bug fix: moderately complex combinations of inline expansions could
+ be miscompiled if the result was declared to be dynamic extent.
+ * bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the
+ form (+ <variable> <integer>) were miscompiled under certain
+ circumstances.
+ * bug fix: in some cases no compiler note about failure to stack allocate
+ was emitted, even if the objects were in fact heap allocated.
+ * bug fix: minor violation of "otherwise inaccessible" rule for stack
+ allocation could cause objects users might reasonably expect to
+ be heap allocated to be stack allocated.
+ * bug fix: DESCRIBE signalled an error for generic functions under
+ certain circumstances. (thanks to Leslie Polzer)
+ * bug fix: Fixed spelling of an error message.
+
+changes in sbcl-1.0.30 relative to sbcl-1.0.29:
+ * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
+ SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
+ of SB-THREAD:THREAD-ERROR-THREAD.
+ * new contrib module: SB-QUEUE provides thread-safe lockless FIFO queues.
+ * new feature: docstrings for local and anonymous functions are no longer
+ discarded. (thanks to Leslie Polzer)
+ * new feature: SB-THREAD:SYMBOL-VALUE-IN-THREAD provides access to symbol
+ values in other threads.
+ * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
+ about object allocation.
+ * optimization: division of a real float by a complex float is implemented
+ with a specialised code sequence.
+ * optimization: MAKE-INSTANCE with non-constant class-argument but constant
+ keywords is an order of magnitude faster.
+ * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+ in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
+ methods, and similarly for non-standard metaclass classes as long as there
+ are no methods additional on MAKE-INSTANCE.
+ * optimization: more efficient type-checks for FIXNUMs when the value
+ is known to be a signed word on x86 and x86-64.
+ * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
+ and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
+ Paul Khuong)
+ * optimization: compiler is smarter about delegating argument type checks to
+ callees.
+ * optimization: several character functions are now compiled somewhat more
+ efficiently. (reported by Lynn Quam)
+ * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
+ * improvement: less unsafe constant folding in floating point arithmetic,
+ especially for mixed complex/real -float operations.
+ * optimization: constant double and single floats are stored in native
+ unboxed format on x86[-64].
+ * optimization: smarter code for arithmetic operations with constant floats,
+ complex floats, or integers on x86[-64].
+ * optimization: smarter code for conjugate/multiplication of float complexes
+ and abs/negate of floats on x86-64.
+ * optimization: more efficient complex float and real float operations on
+ x86-64.
+ * improvement: complex float division is slightly more stable.
+ * improvement: DESCRIBE output has been reworked to be easier to read and
+ contains more pertinent information.
+ * improvement: failure to provide requested stack allocation compiler notes
+ provided in all cases (requested stack allocation not happening without a
+ note being issued is now considered a bug.)
+ * bug fix: SB-POSIX exports the documented types and functions
+ FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
+ types. (reported by "abhi")
+ * bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
+ upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.
+ (thanks to Paul Khuong)
+ * bug fix: looping around HANDLER-CASE could silently consume stack space
+ on each iteration. (reported by "foobar")
+ * bug fix: better error signalling when calls to functions seeking elements
+ from lists (eg. ADJOIN) are compiled with both :TEST and :TEST-NOT.
+ (reported by Tobias Rittweiler)
+ * bug fix: regressions in DIRECTORY from 1.0.28.61: pattern matching of
+ directory components now works as it used to. (various prolems reported by
+ Michael Becker, Gabriel Dos Reis, Cyrus Harmon, and Harald Hanche-Olsen)
+ * bug fix: :PTY option in RUN-PROGRAM was broken with stream arguments.
+ (reported by Elliot Slaughter, thanks to Stas Boukarev)
+ * bug fix: bogus undefined variable warnings from fopcompiled references to
+ global variables. (thanks to Lars Rune Nøstdal)
+ * bug fix: foreign function names should now appear in backtraces on
+ FC6 as well. (reported by Tomasz Skutnik and Tobias Rautenkranz)
+ * bug fix: SETF compiler macro documentation strings are not discarded
+ anymore.
+ * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
+ (thanks to Alex Plotnick)
+ * bug fix: SLEEP accepts large integer arguments, truncating them to
+ SIGNED-WORD on the assumption that sleeping for 68 years is sufficient
+ for anyone. (reported by Leslie Polzer, thanks to Stas Boukarev)
+ * bug fix: compiler notes for expensive slot type checks could be emitted
+ at runtime MAKE-INSTANCE calls. (reported by Samium Gromoff)
+
+changes in sbcl-1.0.29 relative to 1.0.28:
+ * IMPORTANT: bug database has moved from the BUGS file to Launchpad
+ https://bugs.launchpad.net/sbcl
+ Bugs can be reported directly there, or by sending email to
+ sbcl-bugs@lists.sourceforge.net
+ (no subscription required.)
+ * minor incompatible change: under weak type checking policy integer
+ types are weakened less aggressively.
+ * minor incompatible change: SAVE-LISP-AND-DIE :TOPLEVEL function is now
+ allowed to return, which causes SBCL to quit with exit status 0. Previously
+ if the function returned with a small integer return value, that value
+ was accidentally reused as the exit status.
+ * new feature: SB-EXT:DEFINE-HASH-TABLE-TEST allows defining new arguments
+ to MAKE-HASH-TABLE :TEST, and MAKE-HASH-TABLE has been extended with
+ :HASH-FUNCTION argument. Refer to user manual for details.
+ * new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
+ variables.
+ * new feature: SB-EXT:GET-TIME-OF-DAY provides access to seconds and
+ microseconds since the Unix epoch on all platforms.
+ * new feature: SB-EXT:ALWAYS-BOUND proclamation inhibits MAKUNBOUND, and
+ allows the compiler to safely elide boundedness checks for special
+ variables.
+ * new feature: SB-EXT:GLOBAL proclamation inhibits SPECIAL proclamations for
+ the symbol, prohibits both lexical and dynamic binding. This is mainly an
+ efficiency measure for threaded platforms, but also valueable in
+ expressing intent.
+ * new feature: UNC pathnames are now understood by the system on Windows.
+ * optimization: the compiler uses a specialized version of FILL when the
+ element type is know in more cases, making eg. (UNSIGNED-BYTE 8) case
+ almost 90% faster.
+ * optimization: accesses to potentially non-simple arrays where element type
+ is known are 50% faster.
+ * optimization: compiler now generates faster array typechecking code.
+ * optimization: ARRAY-DIMENSION is now faster for multidimensional and
+ non-simple arrays.
+ * optimization: multidimensional array accesses in the absence of type
+ information regarding array rank are approximately 10% faster due to
+ open coding of ARRAY-RANK.
+ * optimization: result of (FILL (MAKE-ARRAY ...) ...) and (REPLACE
+ (MAKE-ARRAY ...) ...) can be stack allocated if the result of MAKE-ARRAY
+ form can be.
+ * optimization: result of call to VECTOR can now be stack allocated.
+ * optimization: MAKE-ARRAY with :INITIAL-CONTENTS is now vastly faster
+ as long as the resulting array is one-dimensional and has a known
+ element type. In particular, :INITIAL-CONTENTS (LIST ...) where the
+ length of the list matches the known length of the vector does not
+ allocate the list as an intermediate step. Ditto for VECTOR and simple
+ backquoted forms.
+ * optimization: MAKE-ARRAY can now stack allocate in the presence of
+ :INITIAL-CONTENTS and :INITIAL-ELEMENT as long as the result has a
+ known element type, and is known to be simple and one dimensional.
+ * improvement: SBCL now emits a compiler note where stack allocation was
+ requested but could not be provided (not in all cases, unfortunately)
+ * improvement: better MACHINE-VERSION responses. (thanks to Josh Elsasser)
+ * improvement: pretty-printing loop has been implemented properly. (thanks
+ to Tobias Rittweiler)
+ * documentation: CLOS slot typechecing policy has been documented.
+ * bug fix: FILE-AUTHOR no longer signals an error on Windows.
+ * bug fix: SB-SPROF could be foiled by foreign code not have a frame
+ pointer, leading to memory faults. (thanks to Bart Botta)
+ * bug fix: better floating point exception handling on x86/OpenBSD.
+ (thanks to Josh Elsasser)
+ * bug fix: exit status from QUIT when called under --script was lost
+ (reported by Hubert Kauker)
+ * bug fix: MAKE-ARRAY for non-zero :INITIAL-ELEMENT always used the
+ same implementation of FILL to initialize the array, even if a more
+ efficient one was available (reported by Stas Boukarev, thanks to
+ Paul Khuong)
+ * bug fix: potential miscompilation of array stack allocation on x86 and
+ x86-64. (reported by Time Tossavainen)
+ * bug fix: some forms of AND, OR, and COND resulted in expansions that could
+ result in their subforms being treated as top level forms. (reported by
+ James Knight)
+ * bug fix: On x86/x86-64 alien functions declared to return integers shorter
+ than a machine register could leave garbage in the high bits of the
+ result register (bug 316325).
+ * bug fix: disable address space randomization Linux/x86-64 as well,
+ not just x86-64. (reported by Ken Olum)
+ * bug fix: Attempting to DEREF an (ALIEN (* T)) would produce a WARNING and
+ generate incorrect code.
+ * bug fix: #201; type inference for CONS and ARRAY types could derive
+ wrong results in the presence of eg. RPLACA or ADJUST-ARRAY.
+ * bug fix: special variables with a proclaimed specific subtype of FUNCTION
+ could not be assigned to or bound with PROGV. (reported by Lorenz
+ Mösenlechner)
+ * bug fix: the value of CL:- in the inspector was the previous expression
+ evaluated rather than the expression being evaluated.
+ * bug fix: constants can no longer be locally declared special.
+ * bug fix: signals delivered to threads started from foreign land (read:
+ directly by pthread_create, not by MAKE-THREAD) are redirected to a Lisp
+ thread by blocking all signals and resignalling.
+ * bug fix: SHARED-INITIALIZE initialized unbound :ALLOCATION :CLASS slots
+ from :INITFORM, if any.
+
+changes in sbcl-1.0.28 relative to 1.0.27:
+ * a number of bugs in cross-compilation have been fixed, with the ultimate
+ result that building under (at least) clisp should be much more reliable.
+ * minor incompatible changes: echo-streams now propagate unread-char to the
+ underlying input stream, and no longer permit unreading more than one
+ character.
+ * improvement: on x86/x86-64 Lisp call frames now have the same layout as C
+ frames, allowing for instance more reliable backtraces.
+ * improvement: the debugger REPL can now reference lexical variables
+ by name directly for code compiled with (DEBUG 3).
+ * improvement: errors from malformed declarations now have better source
+ paths associated with them. (thanks to Tobias Rittweiler)
+ * optimization: faster local calls on x86/x86-64
+ * bug fix: some error messages for out-of-bound array indexes confused the
+ index and the bound. (thanks to Stas Boukarev)
+ * bug fix: pretty printing malformed DEFPACKAGE forms (thanks to Sidney
+ Markowitz)
+ * bug fix: running regressions tests in shells without OSTYPE set now works.
+ (reported by Harald Hanche-Olsen)
+ * bug fix: more robust static space exhaustion signalling from
+ MAKE-STATIC-VECTOR (thanks to Daniel Lowe)
+ * bug fix: (SETF DOCUMENTATION) for anonymous function now throws the
+ docstring away instead of storing it under names such as (LAMBDA (X)).
+ (reported by Leslie Polzer)
+ * bug fix: timers could go off in the wrong order, be delayed indefinitely
+ (thanks to Ole Arndt for the patch)
+ * bug fix: RESTART-FRAME and RETURN-FROM-FRAME stack corruption
+ * bug fix: the discriminating function for PRINT-OBJECT no longer preserves
+ potentially-invalid effective methods in its cache.
+ * bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works with funcallable
+ instances as well (thanks to Paul Khuong)
+ * bug fix: using RUN-PROGRAM does not interfere with SB-POSIX:WAIT,
+ SB-POSIX:WAITPID and their C equivalents.
+ * bug fix: RUN-PROGRAM does not crash on Darwin when stressed.
+
+changes in sbcl-1.0.27 relative to 1.0.26:
+ * new port: support added for x86-64 OpenBSD. (thanks to Josh Elsasser)
+ * new port: support added for x86-64 Solaris. (thanks to Alex Viskovatoff)
+ * improvement: the system either recovers from stack exhaustion or dies
+ properly as opposed to leaving the user uncertain of whether the handler
+ trampled on some random memory next to the stack or having to rely on
+ --lose-on-corruption (which is still a good idea to use in production
+ because stack exhaustion can happen in signal handlers which will likely
+ lead to hangs.)
+ * bug fix: fix gc related interrupt handling bug on ppc (regression from
+ 1.0.25.37, reported by Harald Hanche-Olsen)
+ * bug fix: work around signal delivery bug in darwin (regression from
+ 1.0.25.44, reported by Sidney Markowitz)
+ * bug fix: fix ERROR leaking memory (reported by David Thompson)
+
+changes in sbcl-1.0.26 relative to 1.0.25:
+ * incompatible change: an interruption (be it a function passed to
+ INTERRUPT-THREAD or a timer function) runs in an environment where
+ interrupts can be enabled. The interruption can use
+ WITH-INTERRUPTS or WITHOUT-INTERRUPTS as it sees fit. Use
+ WITHOUT-INTERRUPTS to avoid nesting of interruptions and
+ potentially running out of stack. Keep in mind that in the absence
+ of WITHOUT-INTERRUPTS some potentially blocking operation such as
+ acquiring a lock can enable interrupts.
+ * incompatible change: GC-OFF and GC-ON are removed, as they were
+ always unsafe. Use WITHOUT-GCING instead.
+ * new feature: runtime option --disable-ldb
+ * new feature: runtime option --lose-on-corruption to die at the
+ slightest hint of possibly non-recoverable errors: running out of
+ memory, stack, alien stack, binding stack, encountering a memory
+ fault, etc. In the absence of --lose-on-corruption a warning is
+ printed to stderr.
+ * enhancement: detect binding stack exhaustion
+ * enhancement: detect alien stack exhaustion on x86/x86-64
+ * improvement: generally more stable and reliable interrupt handling
+ * improvement: there is a per thread interruption queue,
+ interruptions are executed in order of arrival
+ * improvement: a repeating timer reschedules itself when the it has
+ finished, but expiration times are spaced equally. If an
+ expiration time is in the past it will trigger after a short grace
+ period that may give a chance to other things to run.
+ * optimization: slightly faster gc on multithreaded builds
+ * optimization: faster WITHOUT-GCING
+ * bug fix: when JOIN-THREAD signals an error, do it when not holding
+ important locks so that the debugger/handler doesn't produce
+ recursive errors or deadlock.
+ * bug fix: real-time signals are not used anymore, so no more
+ hanging when the system wide real-time signal queue gets full.
+ * bug fix: INTERRUPT-THREAD on a dying thread could produce memory
+ fault.
+ * bug fix: finalizers, gc hooks never run in a WITHOUT-INTERRUPTS
+ * bug fix: fix random memory faults related to interrupts on alpha
+ * bug fix: fix random memory faults related to interrupts on sparc
+ * bug fix: fix deadlocks related to starting threads
+ * bug fix: fix deadlines on locks on futex platforms
+ * bug fix: restore errno in signal handlers
+ * bug fix: fix deadlocks related to hash tables
+ * bug fix: fix deadlocks in pcl
+
+changes in sbcl-1.0.25 relative to 1.0.24:
+ * incompatible change: SB-INTROSPECT:FUNCTION-ARGLIST is deprecated, to be
+ removed later. Please use SB-INTROSPECT:FUNCTION-LAMBDA-LIST instead.
+ * new feature: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST allows retrieval of
+ DEFTYPE lambda lists. (thanks to Tobias Rittweiler)
+ * enhancement: MUTEX-VALUE is to be superseded by MUTEX-OWNER that has a
+ better name and does not return values so stale on multiprocessor systems.
+ Also, HOLDING-MUTEX-P was added for about the only sane usage of
+ MUTEX-OWNER.
+ * improvement: unithread builds keep track of MUTEX-VALUE.
+ * improvement: reading from a TWO-WAY-STREAM does not touch the output
+ stream anymore making it thread safe to have a concurrent reader and
+ a writer, for instance, in a pipe.
+ * improvement: GET-SETF-EXPANDER avoids adding bindings for constant
+ arguments, making compiler-macros for SETF-functions able to inspect
+ their constant arguments.
+ * improvement: COMPILE-FILE reports times with millisecond accuracy
+ (thanks to Luis Oliveira)
+ * optimization: CHAR-CODE type derivation has been improved, making
+ TYPEP elimination on subtypes of CHARACTER work better. (reported
+ by Tobias Rittweiler, patch by Paul Khuong)
+ * bug fix: setting alien structure fields of type struct by value now
+ computes the right offset for the memory copy.
+ * bug fix: compilation problem involving inlined calls to aliens with
+ result type VOID. (reported by Ken Olum)
+ * bug fix: #235a; sequential inline expasion in different policies no
+ longer reuses the functional from the previous expansion site.
+ * bug fix: DEFTYPE no longer breaks on bodies consisting of a single
+ unquoted symbol. Regression from 1.0.22.8. (reported by Ariel Badichi)
+ * bug fix: named ENUMs in multiply-referenced alien record types no longer
+ cause an implied type redefinition. Regression from 1.0.21.29.
+ * bug fix: sign-extension of small signed return values now works with C
+ code compiled with gcc 4.3 or newer. (reported by Liam Healy)
+ * improvements to the Windows port:
+ ** SB-BSD-SOCKETS now works from saved cores as well. (reported by Stephen
+ Westfold, thanks to Rudi Schlatte)
+
+changes in sbcl-1.0.24 relative to 1.0.23:
+ * new feature: ARRAY-STORAGE-VECTOR provides access to the underlying data
+ vector of a multidimensional SIMPLE-ARRAY.
* new feature: the system now signals a continuable error if standard
- readtable modification is attempted.
+ readtable modification is attempted. (thanks to Tobias Rittweiler)
+ * new feature: DIRECTORY has been extended with a non-standard keyword
+ argument :RESOLVE-SYMLINKS. (thanks to TC-Rucho)
+ * enhancement: SB-BSD-SOCKETS:MAKE-SOCKET-STREAM keyword argument handling
+ has been robustified and documented better. (thanks to Robert Goldman)
* optimization: faster generic arithmetic dispatch on x86 and x86-64.
+ * optimization: FORMAT ~D and ~F are now approximately 5% faster.
+ * tradeoff: constant FORMAT control strings are now compiled unless
+ SPACE > SPEED (previously only when SPEED > SPACE.)
* bug fix: Red Hat Enterprise 3 mmap randomization workaround. (thanks
to Thomas Burdick)
* bug fix: DEFCLASS and ENSURE-CLASS-USING-CLASS are now expected to
* bug fix: :ALLOCATION :CLASS slots are type-checked properly
in safe code. (reported by Didier Verna)
* bug fix: #430; nested structure constructors can stack allocate.
+ * bug fix: on some 64-bit platforms dynamic space size was truncated
+ to #xffff0000 bytes. (reported by Benjamin Lambert)
+ * bug fix: setting *READ-SUPPRESS* to T no longer renders the default
+ REPL unusable. (reported by Daniel Herring)
+ * bug fix: return values of READ-SEQUENCE did not take :START into
+ account on file streams, regressions since 1.0.12.22. (reported by
+ Thomas Russ, patch by Paul Khuong)
+ * bug fix: using SET or (SETF SYMBOL-VALUE) to change the value of a
+ method specializer used to confuse permuation vector optimization.
+ * bug fix: system inserted bogus implicit type declarations for local
+ special variables in DEFMETHOD bodies.
+ * bug fix: #354; duplicated frames in backtraces due to
+ non-tail-call-optimized XEPs to functions with return type NIL
+ have been elimited.
+ * bug fix: #357; MAKE-INSTANCE/SHARED-INITIALIZE now
+ initializes structure object slots according to DEFSTRUCT initforms,
+ and DEFSTRUCT forms :INCLUDEind structure classes defined using
+ DEFCLASS :METACLASS STRUCTURE-CLASS now inherit their initforms.
+ (reported by Bruno Haible and Stephen Wilson)
+ * bug fix: #395; fill-pointer output streams used now support
+ element-type BASE-CHAR as well.
+ * bug fix: compiler error when attempting to derive return value of
+ ARRAY-ELEMENT-TYPE when the array type was a union of intersection
+ types.
+ * bug fix: address-spaces overlapped on OpenBSD. (thanks to Josh
+ Elsasser)
+ * bug fix: Mac OS X binaries should now be portable between Leopard
+ and Tiger.
changes in sbcl-1.0.23 relative to 1.0.22:
* enhancement: when disassembling method functions, disassembly
type is not know sufficiently well a compile-time are now compiled
correctly. (reported by John Morrison)
* bug fix: compiler no longer makes erronous assumptions in the
- presense of non-foldable SATISFIES types.
+ presence of non-foldable SATISFIES types.
* bug fix: stack analysis missed cleanups of dynamic-extent
arguments in non-let-converted calls to local functions.
* improvements to the Windows port:
default, and DISABLE-DEBUGGER and ENABLE-DEBUGGER also affect
the low-level debugger.
* enchancement: RUN-PROGRAM is now able to extract the file-descriptor
- from SYNONYM-STREAM and TWO-WAY-STEAMS provided they can be decomposed
+ from SYNONYM-STREAM and TWO-WAY-STREAM provided they can be decomposed
down to an SB-SYS:FD-STREAM, allowing direct communication in
more cases. Temporary files and pipes are still used as a fallback
strategy.
