[armedbear-devel] [ANNOUNCE] ABCL 0.23.0
by Erik Huelsmann 25 Nov '10

25 Nov '10

On behalf of the developers of ABCL (Armed Bear Common Lisp) I'm glad to be able to announce the 0.23.0 release. ABCL is a Common Lisp implementation implemented in Java and running on the JVM, featuring both an interpreter and a compiler. The compiler targets the JVM directly meaning that its output is runnable JVM bytecode. The fact that ABCL is written in Java allows for relatively easy embedding in larger applications. For integration with existing applications ABCL implements Java Specification Request (JSR) 223: Java scripting API. This release features - among lots of other things - CLOS thread safety fixes and concurrency improvements, support for Oracle's JRockit JVM, and a new (generic) class file writer. In addition, this is the first release to complete the Maxima test suite without failures, thanks to close cooperation between our projects. You can find the full release notes at: http://common-lisp.net/project/armedbear/release-notes-0.23.shtml and the list of changes at: http://trac.common-lisp.net/armedbear/browser/trunk/abcl/CHANGES If you have questions regarding use or licensing, or you find issues, please report back to the development list: armedbear-devel at common-lisp dot net Source distribution archives can be downloaded in ZIP or gzipped tar form: http://common-lisp.net/project/armedbear/releases/abcl-src-0.23.0.tar.gz http://common-lisp.net/project/armedbear/releases/abcl-src-0.23.0.zip Signatures are available under: http://common-lisp.net/project/armedbear/releases/abcl-src-0.23.0.tar.gz.asc http://common-lisp.net/project/armedbear/releases/abcl-src-0.23.0.zip.asc In addition, binaries are also available: http://common-lisp.net/project/armedbear/releases/abcl-bin-0.23.0.tar.gz http://common-lisp.net/project/armedbear/releases/abcl-bin-0.23.0.zip With associated signatures: http://common-lisp.net/project/armedbear/releases/abcl-bin-0.23.0.tar.gz.asc http://common-lisp.net/project/armedbear/releases/abcl-bin-0.23.0.zip.asc

[armedbear-devel] ANSI regressions in proposed 0.23.x

Unfortunately, I'm seeing the following regressions in the ANSI test suite from 0.22.0 to the 0.23.x branch.

[armedbear-devel] defun return value is not conforming.
by pjb＠informatimago.com 23 Nov '10

23 Nov '10

CLHS says: Macro DEFUN Syntax: defun function-name lambda-list [[declaration* | documentation]] form* => function-name Arguments and Values: function-name---a function name. and the glossary: function name n. 1. (in an environment) A symbol or a list (setf symbol) that is the name of a function in that environment. 2. A symbol or a list (setf symbol). Therefore (defun f () ...) should return the symbol F, not the function F. Unfortunately, after having loaded quicklisp, it looks like abcl switches to another definition, which returns a function instead of a name: (macroexpand '(defun (x) (1+ x))) Before: (SYSTEM:%DEFUN (QUOTE F) (LAMBDA (X) (BLOCK F (1+ X)))) (correct) After: (PROGN (SYSTEM:%DEFUN (QUOTE F) (SYSTEM:NAMED-LAMBDA F (X) (BLOCK F (1+ X))))) WRONG. -- __Pascal Bourguignon__ http://www.informatimago.com/ A bad day in () is better than a good day in {}.

[armedbear-devel] New classwriter no longer preserves Lisp source line numbers
by Mark Evenson 22 Nov '10

22 Nov '10

I just noticed that I no longer see Lisp source line numbers in our backtraces. I'm assuming this is a property of the new classwriter. For debugging, this seems like a serious regression as we already had a paucity of debug information (no way to inspect the frames, no stepped, etc.) Having the line number of the form associated with the stack frame at least gave a bit of a clue as to where to look for the source of a condition. Is my presumption if the lossage stemming from the new classwriter correct? Would it be easy to restore? We seem to be including the ordinal of the top level form in the class name (i.e. "org.armedbear.lisp.ASDF_TMP_installer_51.execute(installer.lisp)" contains the result of compiling the 51st top-level form in 'installer.lisp'), so it should be fairly easy to include a single entry in the LineNumberTable attribute linking the start of the class code with the Lisp source. -- "A screaming comes across the sky.

[armedbear-devel] Conformity and convenience problems with pathnames
by pjb＠informatimago.com 21 Nov '10

21 Nov '10

Hello, It is well known that implementations of CL pathnames have been greatly implementation dependant. However, the standard still specifies clear behavior for logical pathnames, for one thing, and for the other, since there are several implementations working on the same POSIX systems (unix including linux and MacOSX; and MS-Windows), it is desirable that all implementations converge in their handling of pathnames on these plateforms. Personnaly, I resolved to use logical pathnames and logical-pathname translations as much as possible, and to use make-pathname to build portably physical pathnames. However, most implementations have problems dealing with these two aspects. To improve the situation, I wrote a little script to check the behavior of implementations in these two aspects. The script can be found at: ftp://ftp.informatimago.com/users/pjb/lisp/check-pathnames.lisp Since I'm sending a similar message to most implementation lists, it might be better, if there is any need for 'language lawyer' discussions, to direct them to news:comp.lang.lisp.

[armedbear-devel] Patch to get BORDEAUX-THREADS working on post abcl-0.23.0
by Mark Evenson 20 Nov '10

20 Nov '10

As part of my ongoing task of keeping Hunchentoot working with ABCL, I noticed BORDEAUX-THREADS currently (as of 0.8.0) doesn't work with abcl-0.23 or later as we deprecated the thread interface it relies on. I've [created patch][1] that fixes this as well as actually providing an implementation of the CONDITION-WAIT/CONDITION-NOTIFY primitives, which had stopped working due to bit rot in BORDEAUX-THREADS. There is still a little funkiness in the bordeaux-threads-test suite which sometimes seems to generate errors, but I think this is from MOP issues in the fiveam, but I'm not exactly sure.

CL-USER(7): (asdf-install:install 'hunchentoot) Install where? 1) System-wide install: System in /usr/local/asdf-install/site-systems/ Files in /usr/local/asdf-install/site/ 2) Personal installation: System in /home/raison/.asdf-install-dir/systems/ Files in /home/raison/.asdf-install-dir/site/ 0) Abort installation. --> 2 ;;; ASDF-INSTALL: Downloading 139617 bytes from http://weitz.de/files/hunchentoot.tar.gz to /home/raison/asdf-install-0.asdf-install-tmp ... #<THREAD "interpreter" {4DA42824}>: Debugger invoked on condition of type STREAM-ERROR Input value 0xdc4a is malformed while recoding with charset UTF-8 Restarts: 0: TOP-LEVEL Return to top level.
