sbcl 1.0.18 released

Juho Snellman — 2008-06-29T22:22:33

Source is available in SourceForge CVS and on the SourceForge File Releases page. 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. * enhancement: better pretty-printing of DEFPACKAGE forms. (Thanks to Michael Weber) * 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

sbcl-1.0.17 has been released

Christophe Rhodes — 2008-05-28T13:37:15

Source is available in SourceForge CVS and on the SourceForge File Releases page. Under some conditions (as yet slightly uncertain; see sbcl-devel), the a stress-test of times in SBCL's regression test suite can cause SBCL to deadlock. It is currently believed that this is not in fact a regression, but it is possible that some rearrangement of code has caused this failure mode to become more likely: if your code depends on timers, proceed with care (and please report any failures you observe to sbcl-devel, to help the diagnosis and cure). Best, Christophe from the NEWS file in the distribution: 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. * enhancemen

sbcl-1.0.16 has been released (not sbcl-1.1 afterall)

William Harold Newman — 2008-04-14T00:36:06

This was originally intended as a particularly stable release. Now, instead, it's back to being a (more belated than usual) timeboxed release. There's an annoying ASDF misbehavior for which we don't have a slamdunk fix; see sbcl-devel for discussion. from the NEWS file in the distribution: 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 bu

1. sbcl-1.0.15 has been released,and 2. upcoming sbcl-1.1

William Harold Newman — 2008-02-26T18:42:54

sbcl-1.0.15 is in the SourceForge file release system now; enjoy. In unrelated sbcl-announce - ish news, the next release is expected to be called sbcl-1.1. For details, see sbcl-devel. The high level summary is: * Its freeze period is expected to start at the customary 20th-of-the-month-ish time, but instead of releasing it around the 25th, we'll probably poke at it a little longer than usual. * There is some interest in using it (and then occasional successive future releases) as the base for more-stable less-patched branches, something like the Linux stable branches. 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

SBCL 1.0.14 has been released.

William Harold Newman — 2008-01-28T14:14:08

Source is available in SourceForge CVS and on the SourceForge File Releases page. from the NEWS file in the distribution: 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 ...) frame

SBCL 1.0.13 has been released.

William Harold Newman — 2007-12-27T15:02:07

Sources are in CVS and on the SourceForge File Releases page, ho ho ho. 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 on 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

SBCL 1.0.12 has been released.

William Harold Newman — 2007-11-26T14:29:41

It is in CVS and on the File Releases webpage at SourceForge now; enjoy. 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 magnitue 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

SBCL version 1.0.11 has been released.

William Harold Newman — 2007-10-25T22:39:06

sbcl-1.0.11 sources are in CVS and on the SourceForge File Releases page now; enjoy. from the NEWS file in the distribution: 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 from multiple threads can give inconsistent results or even corrupt the hash-table completely. Multi-threaded applications should do their own 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 CONS did

sbcl-1.0.10 has been released.

William Harold Newman — 2007-09-25T21:53:48

It is available in SourceForge CVS and on the File Releases pages. changes in sbcl-1.0.10 relative to sbcl-1.0.9: * minor incompatible change: the MSI installer on Windows no longer associates .lisp and .fasl files with the installed SBCL. * minor incompatible change: :UNIX is no longer present in *FEATURES* on Windows. (thanks to Luis Oliviera) * new feature: SB-CLTL2 contrib module now implements FUNCTION-INFORMATION. (thanks to Larry D'Anna) * optimization: scavenging weak pointers is now more efficient, requiring O(1) instead of O(N) per weak pointer to identify scanvenged vs. unscavenged pointers. (thanks to Paul Khuong) * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in method bodies using constant slot-names when the first argument is a specializer parameter for the method. * optimization: SLOT-VALUE &co are now ~50% faster for variable slot names, when the class of the instance is a direct instance STANDARD-CLASS or FUNCALLABLE-STANDAR

sbcl-1.0.9 has been released

William Harold Newman — 2007-08-27T01:29:28

and should be available on sf.net CVS repository and File Releases page. from the NEWS file in the distribution: changes in sbcl-1.0.9 relative to sbcl-1.0.8: * minor incompatible change: SB-SYS:OUTPUT-RAW-BYTES is deprecated. * enhancement: SB-EXT:FINALIZE accepts a :DONT-SAVE keyword argument, indicating the finalizer should be cancelled when SAVE-LISP-AND-DIE is called. * enhancement: default PRINT-OBJECT methods for classes, slot-definitions, and generic function now print the object identity for anonymous instances. (thanks to Attila Lendvai) * enhancement: as an extension to MOP, SBCL now supports SETF of STANDARD-INSTANCE-ACCESS and FUNCALLABLE-STANDARD-INSTANCE-ACCESS. (thanks to Attila Lendvai) * enhancement: sb-cover has an alternate annotation mode which puts the form annotations at the car of the form, instead of annotating it completely. The benefit of this mode is that it shows better which forms were instrumented by the compiler. * bug fix: new

sbcl-1.0.8 has been released

William Harold Newman — 2007-07-25T16:37:34

It should be available on your favorite SourceForge venue now. changes in sbcl-1.0.8 relative to sbcl-1.0.7: * 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 (overriding proclamations and declarations). * enhancement: closed over variables can be stack-allocated on x86 and x86-64. * performance bug fix: GETHASH and (SETF GETHASH) are once again non-consing. * optimization: slot definition lookup is now O(1). This speeds up eg. SLOT-VALUE and (SETF SLOT-VALUE) with variable slot names. * optimization: STRING-TO-OCTETS is now up to 60% faster for UTF-8. * optimization: ASSOC and MEMBER can now be open-coded for all combinations of keyword arguments when second argument is constant and SPEED >= SPACE. In other cases a specialized version is selected. *

two changes in SBCL mailing list policy

William Harold Newman — 2007-07-09T17:15:50

I have just made one change in policy on sbcl-devel and sbcl-help: posts from nonsubscribers are now disabled in hopes of reducing spam. I also noticed an option for another change that I might make: perhaps the size cutoff for postings should be more than 40kB? My impression (as the person who belatedly approves them) is that 57kB posts on sbcl-devel are usually appropriate things like patches. I am inclined to bump the limit for sbcl-devel up to 80kB-100kB or so, and to bump the limit for sbcl-commits up to something like 200kB. However, I'd like to give subscribers a chance to comment on it first: if you like to read sbcl-devel through your slow ham radio link from your sailboat off the coast of Antarctica and don't want it to clog up your connection, now's a good time to let me know.

sbcl-1.0.7 has been released.

William Harold Newman — 2007-06-28T01:45:21

Its source should be available from the usual SourceForge sites already, its binaries presently. from the NEWS file in the distribution: changes in sbcl-1.0.7 relative to sbcl-1.0.6: * MOP improvement: support for user-defined subclasses of SB-MOP:SPECIALIZER has been enhanced. The experimental interface function SB-PCL:MAKE-METHOD-SPECIALIZERS-FORM, called as part of the expansion of DEFMETHOD, is responsible for generating a form which creates a list of specializers when evaluated. Additional functions SB-PCL:[UN]PARSE-SPECIALIZER-USING-CLASS provide debugging and introspective support. * minor incompatible change: the (unsupported) spinlock interface has changed: free spinlock now has the value NIL, and a held spinlock has the owning thread as its value. * enhancement: WITHOUT-INTERRUPTS now binds ALLOW-WITH-INTERRUPTS and WITH-LOCAL-INTERRUPTS as local macros. Refer to documentation string for details. * enhancement: name of a socket-stream is now "a soc

sbcl-1.0.6 has been released.

William Harold Newman — 2007-05-27T02:08:43

It's in SourceForge CVS and on the SourceForge File Releases page. from the NEWS file in the distribution: changes in sbcl-1.0.6 relative to sbcl-1.0.5: * new contrib: sb-cover, an experimental code coverage tool, is included as a contrib module. * optimization: STRING-TO-OCTETS for unibyte encodings and UTF-8 is significantly faster. * optimization: calls of the form (AREF FOO (+ INDEX )) now produce more efficient code on x86-64 if the compiler can determine that (+ INDEX ) does not require a bounds check and FOO has an element type at least 8 bits wide. * enhancement: a new, experimental synchronous timeout facility is provided. Refer to SB-SYS:WITH-DEADLINE for details. * enhancement: when a symbol name conflict error arises, the conflicting symbols are always printed with a package prefix. (thanks to Kevin Reid) * enhancement: stepping is now once again supported on the SPARC and MIPS platforms. (It is also now more likely to work on

sbcl-1.0.5 has been released

William Harold Newman — 2007-04-28T20:58:45

Its source is available in the usual SourceForge-ish places; enjoy. from the NEWS file in the distribution: changes in sbcl-1.0.5 relative to sbcl-1.0.4: * incompatible change: removed writer methods for host-ent-name, host-ent-addresses -- changing the values did not update the DNS information anyway. * minor incompatible change: changed experimental JOIN-THREAD interface * documentation: the manual now lists reader and writer methods in class slot documentation sections. (thanks to Richard M Kreuter) * documentation: unwinding from asyncronous events has been documented as unsafe. * documentation: SB-SYS:WITHOUT-GCING has been documented as unsafe in multithreaded application code. * optimization: GET-INTERNAL-REAL-TIME has been optimized on POSIX platforms. (thanks to James Anderson for the optimization hint) * optimization: REPLACE, SUBSEQ, and COPY-SEQ are now optimized in more cases. * optimization: STRING-{EQUAL,LESSP,GREATER-P} and their NOT- variants

sbcl-1.0.4 has been released

William Harold Newman — 2007-03-25T19:05:40

All its source-ey goodness is available from SourceForge CVS service or File Releases web page. Use it wisely. from the NEWS file in the distribution: changes in sbcl-1.0.4 relative to sbcl-1.0.3: * new platform: experimental support for x86-64/darwin (MacOS). * incompatible change: the thread-safe (on most platforms) getaddrinfo and getnameinfo sockets functions are used instead of gethostbyaddr and gethostbyname, on platforms where the newer functions are available. As a result, the ALIASES field of HOST-ENT will always be NIL on these platforms. * change: runtimes with embedded cores (i.e. saved with :EXECUTABLE T) don't print the startup banner, but behave as if --noinform was passed as a command line argument. (thanks to Kevin Reid) * new experimental feature: added JOIN-THREAD (by NIIMI Satoshi) * optimization: code using alien values with undeclared types is much faster. * optimization: the compiler is now able to open code SEARCH in more cases. * optimization: m

sbcl-1.0.3 has been released

William Harold Newman — 2007-02-27T23:21:42

It has been tagged in CVS and a source tarball is available on the File Releases page. Enjoy. from the NEWS file in the distribution: changes in sbcl-1.0.3 relative to sbcl-1.0.2: * new platform: NetBSD/PPC. (thanks to Aymeric Vincent) * optimization: calls of the form (AREF FOO (+ INDEX )) now produce more efficient code on the x86 if the compiler can determine that (+ INDEX ) does not require a bounds check and FOO has an element type at least 8 bits wide. * bug fix: references to undefined variables are handled the same way in toplevel forms as in the normal compiler * bug fix: the build scripts again work with non-bash /bin/sh (thanks to Magnus Henoch) * bug fix: use "gtar" as the asdf-install *TAR-PROGRAM* on NetBSD (thanks to Jon Buller) * improvement: faster compilation times for complex functions * improvement: added readlink support to SB-POSIX (thanks to Richard M Kreuter)

sbcl-1.0.2 has been released

William Harold Newman — 2007-01-25T17:14:58

The source tarball is on the SourceForge file releases page, and it is tagged in CVS. Enjoy. from the NEWS file in the distribution: changes in sbcl-1.0.2 relative to sbcl-1.0.1: * improvement: experimental support for mach exception handling on x86/macos. requires building with :MACH-EXCEPTION-HANDLER feature to use. * improvement: support for GBK external format. (thanks to Chun Tian (binghe)) * improvement: the debugger now displays variables that have been closed over, in code compiled with (DEBUG 2) or higher * improvement: support for executable cores on NetBSD (thanks to Richard Kreuter) * new feature: added a RESTART-FRAME debugger command * new feature: new generic function SB-GRAY:STREAM-FILE-POSITION can be used to provide an implementation for FILE-POSITION on Gray streams (thanks to Eric Marsden) * new feature: add syslog, openlog and closelog support to SB-POSIX (thanks to Richard Kreuter) * optimization: the function call overhead in code com

SBCL 1.0.1 has been released.

William Harold Newman — 2006-12-26T16:40:26

It is tagged in CVS and up on the File Releases page at SourceForge. Enjoy, and merry New Year. from the NEWS file in the distribution: 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) and special variables (who-binds, who-sets, who-references) for code compiled with (< SPACE 3). This information is available through the sb-introspect contrib. * new feature: users may subclass SEQUENCE, and have instances of these classes interoperate with standard Common Lisp functions if a number of methods are defined. (This feature is experimental and the interface subject to change based on feedback from SBCL users and the general community) * improvement: sb-sprof traces call stacks to an arbitrary depth on x86/x86-64, rather than the previous fixed depth of 8 * improvement: anothe

The sbcl-announce list is now 100% human-moderated.(Re: spam)

William Harold Newman — 2006-12-13T18:05:45

first, a proper announcement: I have tweaked the list configuration to enable what Mailman calls "emergency moderation": all postings should be held until I surf to the admin URL, give the admin password, and click radiobuttons to determine their fate. This seems a very practical solution for such a low-traffic list, and assuming that it works as documented, it should reliably stop spam on sbcl-announce, which should return to being a SBCL announcements list, probably mostly monthly release announcements as before. then, some words of explanation and discussion: On Wed, Dec 13, 2006 at 11:28:36AM -0500, Perry E.
