+changes in sbcl-1.0.18 relative to 1.0.17:
+ * minor incompatible change: SB-SPROF:WITH-PROFILING now by default
+ profiles only the current thread.
+ * minor incompatible change: changes to SYMBOL-VALUE of constants
+ defined with DEFCONSTANT now signal an error.
+ * enhancement: SB-SPROF now has support for wallclock profiling,
+ and is also able to profile specific threads. REPORT output
+ has also additional sorting options.
+ * optimization: structure allocation has been improved
+ ** constructors created by non-toplevel DEFSTRUCTs are ~40% faster.
+ ** out of line constructors are ~10% faster.
+ ** inline constructors are ~15% faster.
+ ** inline constructors are capable of dynamic extent allocation
+ (generally on x86 and x86-64, in some cases on other platforms
+ as well.)
+ * optimization: simple uses of HANDLER-CASE and HANDLER-BIND no
+ longer cons.
+ * optimization: file compiler is now able to coalesce non-circular
+ lists, non-base strings, and bit-vectors. Additionally, constants
+ are never referenced through SYMBOL-VALUE at runtime.
+ * bug fix: EAI_NODATA is deprecated since RFC 3493. Stop using it
+ in sb-bsd-sockets.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** NIL is a valid function name (regression at 1.0.13.38)
+ ** FILL on lists was missing its return value (regression at 1.0.12.27)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ fill pointers properly (regression at 1.0.12.23)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ displacement indices properly (regression at 1.0.12.23)
+
+changes in sbcl-1.0.17 relative to 1.0.16:
+ * temporary regression: user code can no longer allocate closure
+ variable storage on stack, due to bug 419 without explicitly
+ requesting it. Please consult sbcl-devel for advice if you need to
+ use this feature in the meanwhile.
+ * new feature: runtime argument --control-stack-size can be used to
+ adjust thread default control stack size.
+ * enhancement: improved TIME output
+ ** all times are reported using the measured accuracy (milliseconds
+ for real and GC times, microseconds for everything else.)
+ ** processor cycle counts on x86 and x86-64.
+ ** interpreted forms are counted for both evaluator modes.
+ ** number of lambdas converted by the compiler is reported.
+ ** CPU percentage report (computed from real and total run time.)
+ ** more comprehensive run time reporting, using a condenced format
+ ** interperted form, lambda, and page fault counts are omitted
+ when zero.
+ * optimization: ADJOIN and PUSHNEW are upto ~70% faster in normal
+ SPEED policies.
+ * optimization: APPEND is upto ~10% faster in normal SPEED policies.
+ * optimization: two argument forms of LAST are upto ~10% faster
+ in normal SPEED policies.
+ * optimization: NCONC no longer needs to heap cons its &REST list
+ in normal SPEED policies.
+ * bug fix: SB-FLUID build feature no longer breaks the build. (thanks
+ to Sidney Markowitz)
+ * bug fix: UNION and NUNION work with :TEST-NOT once more,
+ regression since 1.0.9.1. (thanks to Eric Marsden)
+ * bug fix: result of MAKE-ARRAY can be stack allocated - regression
+ since 1.0.15.36. (thanks to Paul Khuong)
+ * bug fix: LAST when always returned the whole list when given a bignum
+ as the second argument.
+ * bug fix: dynamic extent allocation of nested lists and vectors
+ could leak to otherwise accessible parts.
+ * bug fix: invalid optimization of heap-allocated alien variable
+ reference.
+ * bug fix: fasl header checking is less vulnerable to different
+ platform word lengths.
+ * bug fix: more correct assembler syntax for GNU binutils
+ 2.18.50.0.4 support. (thanks to Marijn Schouten)
+ * bug fix: fix ECASE warnings from CMUCL-as-xc-host. (reported by
+ Andreas Franke)
+ * bug fix: the fopcompiler can handle LOCALLY forms (with no
+ declarations) successfully. (reported by Attila Lendvai)
+
+changes in sbcl-1.0.16 relative to 1.0.15:
+ * minor incompatible change: revert the changes to sb-posix's error
+ signaling added in 1.0.14.
+ * minor incompatible change: change PROBE-FILE back to returning
+ NIL whenever we can't get a truename, as was the case before 1.0.14.
+ * minor incompatible change: SB-BSD-SOCKETS:NAME-SERVICE-ERROR now
+ inherits from ERROR instead of just CONDITION.
+ * new feature: SB-INTROSPECT can provide source locations for instances
+ as well. (thanks to Tobian Ritterweiler)
+ * optimization: binding special variables now generates smaller code
+ on threaded platforms.
+ * optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ
+ and cases where no :TEST is given but the compiler can infer that
+ the element to search is of type (OR FIXNUM (NOT NUMBER)).
+ * optimization: better LOGNOT on fixnums.
+ * optimization: modular arithmetic for a particular requested width
+ is implemented using a tagged representation unless a better
+ representation is available.
+ * fixed bug 423: TRULY-THE and *CHECK-CONSISTENCY* interaction.
+ * bug fix: SB-BSD-SOCKETS:MAKE-INET-ADDRESS checks the input string
+ for wellformedness and returns a specialized vector. (reported by
+ Francois-Rene Rideau)
+ * bug fix: FIND-CLASS was not thread-safe. (reported by Attila Lendvai)
+ * bug fix: ~R was broken for vigtillions. (thanks to Luis Oliveira)
+ * bug fix: attempt to obtain *SCHEDULER-LOCK* recursively when
+ unscheduling timer at the same time as another timer fires.
+ * bug fix: don't reschedule timers for dead threads.
+ * bug fix: periodic polling was broken. (thanks to Espen S Johnsen)
+ * bug fix: copying output from RUN-PROGRAM to a stream signalled
+ bogus errors if select() was interrupted.
+ * enhancement: add support for fcntl's struct flock to SB-POSIX.
+
+changes in sbcl-1.0.15 relative to sbcl-1.0.14:
+ * enhancement: cleaner backtraces for interactive interrupts, as
+ well as other cases where the interesting frames used to be
+ obscured by interrupt handling frames.
+ * enhancement: untracing a whole package using (UNTRACE "FOO") is
+ now supported, and tracing a whole package using (TRACE "FOO") now
+ traces SETF-functions as well.
+ * enhancement: implement SB-POSIX:MKTEMP and SB-POSIX:MKDTEMP.
+ * SB-DEBUG:PRINT-FRAME-CALL now prints the entry-point kind even
+ when SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS* is NIL.
+ * unreadably printed representation of hash-tables now includes
+ weakness if any.
+ * bug fix: partially fixed #188: type propagation from assignments
+ is now more efficient.
+ * bug fix: fixed #407: (COERCE X 'SINGLE-FLOAT) and (COERCE X
+ 'DOUBLE-FLOAT) are not flushable.
+ * bug fix: on x86 and x86-64 pointer based EQ-hashing now uses the
+ full address of the object, and none of the tag bits.
+ * bug fix: readably printing hash-tables now respects other printer
+ control variables. (reported by Cedric St-Jean)
+ * bug fix: compiler gave a bogus STYLE-WARNING for the :SYNCHRONIZED
+ keyword with MAKE-HASH-TABLE.
+ * bug fix: export SB-POSIX:MKSTEMP.
+ * bug fix: SORT was not interrupt safe.
+ * bug fix: XREF accounts for the last node of each basic-block as
+ well.
+ * bug fix: MAKE-INSTANCE optimizations interacted badly with
+ non-keyword :DEFAULT-INITARGS in the presence of :BEFORE/:AFTER
+ methods on SHARED-INITIALIZE. (thanks to Matt Marjanovic)
+ * bug fix: the CTOR optimization for MAKE-INSTANCE should no longer
+ create obsolete instances in the case of redefinition or
+ obsoletion of a superclass. (thanks to Andy Hefner)
+ * bug fix: Support for the Alpha architecture has been revived; it had
+ suffered somewhat from lack of maintenance since sbcl-1.0.
+ * improvements to the Windows port:
+ ** The system detects the codepage to use at startup, instead of
+ using the value from the saved core. (thanks to Kei Suzuki)
+
+changes in sbcl-1.0.14 relative to sbcl-1.0.13:
+ * new feature: SB-EXT:*EXIT-HOOKS* are called when the process exits
+ (see documentation for details.)
+ * revived support for OpenBSD (contributed by Josh Elsasser)
+ * partially fixed bug #108: ROOM no longer suffers from occasional
+ (AVER (SAP= CURRENT END)) failures.
+ * fixed bug #402: proclaimed non-standard declarations in DEFMETHOD
+ bodies no longer cause a WARNING to be signalled. (reported by
+ Vincent Arkesteijn)
+ * bug fix: (TRUNCATE X 0) when X is a bignum now correctly signals
+ DIVISION-BY-ZERO. Similarly for MOD and REM (which suffered due to
+ the bug in TRUNCATE.) (reported by Michael Weber)
+ * bug fix: SB-SPROF:REPORT no longer signals an error if there are
+ no samples. (reported by Andy Hefner)
+ * bug fix: functions compiled using (COMPILE NIL '(LAMBDA ...))
+ no longer appear as (NIL ...) frames in backtraces.
+ * bug fix: RESOLVE-CONFLICT (and the other name conflict machinery)
+ is now actually exported from SB-EXT as documented. (reported by
+ Maciej Katafiasz)
+ * bug fix: sb-aclrepl now correctly understands how to inspect
+ single-floats on 64-bit platforms where single-floats are not boxed.
+ * bug fix: SB-MOP:CLASS-SLOTS now signals an error if the class has not
+ yet been finalized. (reported by Levente Meszaros)
+ * bug fix: CLOSE :ABORT T behaves more correctly on Windows.
+ * DESCRIBE and (DOCUMENTATION ... 'OPTIMIZE) describe meaning of
+ SBCL-specific optimize qualities.
+
+changes in sbcl-1.0.13 relative to sbcl-1.0.12:
+ * minor incompatible change: RUN-PROGRAM now uses execvp(3) to find
+ an executable in the search path, and does so in the child
+ process's PATH. The function FIND-EXECUTABLE-IN-SEARCH-PATH has
+ been removed; it can be found in the CVS history, for somebody who
+ needs that search behavior (see the manual).
+ * minor incompatible change: compiler policy re. weakening type
+ checks has changed: now type checks are weakened only if SAFETY < 2
+ and SAFETY < SPEED.
+ * SB-EXT:NATIVE-NAMESTRING takes a new keyword AS-FILE, forcing
+ unparsing of directory pathnames as files. Analogously,
+ SB-EXT:PARSE-NATIVE-NAMESTRING takes an AS-DIRECTORY, forcing a
+ filename to parse into a directory pathname.
+ * enhancement: implicit generic function creation now signals a
+ specific style-warning IMPLICIT-GENERIC-FUNCTION-WARNING, which
+ users can bind handlers for and muffle around calls to LOAD.
+ * enhancement: RUN-PROGRAM allows unicode arguments and environments
+ to be used (using the default stream external format), and allows
+ non-simple strings to be used. (thanks to Harald Hanche-Olsen)
+ * optimization: COPY-SEQ, FILL, and SUBSEQ are 30-80% faster for
+ strings and vectors whose element-type or simplicity is not fully
+ known at compile-time.
+ * optimization: STRING-TRIM and related functions no longer allocate
+ a new string when no trimming needs to be performed. These functions
+ are also faster than before when the input string has been declared
+ as a simple-string.
+ * optimization: READ-SEQUENCE on simple-strings is up to 80% faster.
+ * optimization: READ-LINE is significantly faster for files containing
+ long lines.
+ * optimization: non-open coded uses of character comparison operators
+ (e.g. char=) no longer cons when called with more than one parameter
+ on platforms supporting dynamic-extent allocation.
+ * bug fix: READ-SEQUENCE on composite stream wrapping a Gray stream
+ with STREAM-ELEMENT-TYPE (UNSIGNED-BYTE 8) signalled an error.
+ * bug fix: COPY-SEQ on lists did not signal a type-error on improper
+ lists in safe code.
+ * bug fix: some sequence functions elided bounds checking when
+ SPEED > SAFETY.
+ * bug fix: too liberal weakening of union-type checks when SPEED >
+ SAFETY.
+ * bug fix: more bogus fixnum declarations in ROOM implementation
+ have been fixed.
+
+changes in sbcl-1.0.12 relative to sbcl-1.0.11:
+ * new feature: MAKE-HASH-TABLE now experimentally accepts a
+ :SYNCHRONIZED argument, which makes the hash-table safe for
+ concurrent accesses (but not iteration.) See also:
+ SB-EXT:WITH-LOCKED-HASH-TABLE, and
+ SB-EXT:HASH-TABLE-SYNCHRONIZED-P.
+ * optimization: CONCATENATE on strings is an order of magnitude faster
+ in code compiled with (> SPEED SPACE).
+ * optimization: SUBSEQ is ~50% faster on lists.
+ * bug fix: bug 417 fixed -- source location reporting is now more robust.
+ * bug fix: SUBSEQ on a list will now correctly signal an error if if
+ END is smaller then START.
+ * bug fix: SB-PROFILE will no longer report extra consing for nested
+ calls to profiled functions.
+ * bug fix: ROOM implementation had bogus fixnum declarations which
+ could cause type-errors when calling ROOM on large images.
+ * bug fix: if file compilation is aborted, the partial fasl is now
+ deleted, and COMPILE-FILE returns NIL as the primary value.
+ * bug fix: number of thread safety issues relating to SBCL's internal
+ hash-table usage have been fixed.
+ * bug fix: SB-SYS:WITH-PINNED-OBJECTS could cause garbage values to
+ be returned from its body when the values were being returned
+ using unknown-values return convection and the W-P-O was wrapped
+ inside an UNWIND-PROTECT.
+ * bug fix: sb-posix should now compile again under Windows, enabling
+ slime to work again.
+
changes in sbcl-1.0.11 relative to sbcl-1.0.10:
* incompatible change: hash-table accessor functions are no longer
automatically protected by locks. Concurrent accesses on the same hash-table
locking at the correct granularity. In the current implementation it is
still safe to have multiple readers access the same table, but it's not
guaranteed that this property will be maintained in future releases.
+ * minor incompatible change: (SETF MUTEX-VALUE) is not longer supported,
+ and will signal an error at runtime.
* enhancement: SB-THREAD package now exports a semaphore interface.
* enhancement: CONS can now stack-allocate on x86 and
x86-64. (Earlier LIST and LIST* supported stack-allocation, but
* enhancement: dynamic-extent support has been extended to support
cases where there are multiple possible sources for the stack
allocated value.
+ * optimization: RELEASE-MUTEX no longer needs to perform a syscall
+ if the mutex is uncontested on Linux.
* bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK*
as specified by the CLHS. (thanks to Tobias Rittweiler)
+ * bug fix: NaN comparison now works on x86-64.
+ * bug fix: CLOSE :ABORT T on a stream with pending output now
+ works.
+ * bug fix: instances of non-standard metaclasses using standard
+ instance structure protocol sometimes missed the slot type checks
+ in safe code.
+ * bug fix: known functions can be inlined in high-debug code.
changes in sbcl-1.0.10 relative to sbcl-1.0.9:
* minor incompatible change: the MSI installer on Windows no longer
could cause buffer-overflows.
* bug fix: source location information is stored correctly
(broken since 1.0.6). This bug would generally show up as the
- Slime debugger higlighting the wrong form when the sldb-show-source
+ Slime debugger highlighting the wrong form when the sldb-show-source
command was used.
* bug fix: Branch forms are again annotated as branches in the sb-cover
annotations.
* enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
atomic compare-and-swap operations on threaded platforms.
* enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
- allows assining a global minimum value to optimization qualities
+ allows assigning a global minimum value to optimization qualities
(overriding proclamations and declarations).
* enhancement: closed over variables can be stack-allocated on x86
and x86-64.
* bug fix: number of characters that can be written onto a single
line in a file is unlimited.
* bug fix: some GC deadlocks caused by asynchronous interrupts have
- been fixed by inhibiting interrupts for when GC is disbled.
+ been fixed by inhibiting interrupts for when GC is disabled.
* bug fix: some interrupt safety issues with GETHASH, (SETF
GETHASH), CLRHASH and REMHASH have been fixed.
* bug fix: binding *BREAK-ON-SIGNALS* to a value that is not a type
changes in sbcl-1.0.1 relative to sbcl-1.0:
* new platform: FreeBSD/x86-64, including support for threading.
* new feature: the compiler stores cross-referencing information
- abount function calls (who-calls), macroexpansion (who-macroexpands)
+ about function calls (who-calls), macroexpansion (who-macroexpands)
and special variables (who-binds, who-sets, who-references) for code
compiled with (< SPACE 3). This information is available through the
sb-introspect contrib.
