[armedbear-devel] ASDF: Cannot handle the special form EXTENSIONS:TRULY-THE
by Blake McBride 24 Mar '13

24 Mar '13

Greetings, Trying to load a package with ASDF I ran into the following error: ASDF could not load because Cannot (currently) handle the special form EXTENSIONS:TRULY-THE. #<THREAD "interpreter" {4BC78066}>: Debugger invoked on condition of type SIMPLE-ERROR Cannot (currently) handle the special form TRULY-THE Restarts: ... I traced the problem to ASDF and not the package I was attempting to load. Does anyone know anything about this? (I am running the latest SVN head of ABCL) Thanks. Blake McBride

[armedbear-devel] destroy-thread and unwind-protect
by James Lawrence 08 Aug '12

08 Aug '12

(defun test-cleanup () (let* ((cleanedp nil) (thread (threads:make-thread (lambda () (unwind-protect (sleep 999) (setf cleanedp t)))))) (sleep 0.5) (threads:destroy-thread thread) (sleep 0.5) cleanedp)) (test-cleanup) ABCL-1.0.0 and ABCL-0.27.0 return NIL. Other implementations I tested all return T -- Allegro, Clozure, LispWorks, SBCL (changing "threads" to "bordeaux-threads"). Of course this isn't a bug since ABCL is free to do what it wishes. Does ABCL wish that?

[armedbear-devel] invoke.lisp can't find jsint.Invoke

Ladies and Gentlemen, I've been trying to run ABCL with JSS. I load ABCL then I try to '(load "invoke.lisp")'. I always get an error Peters-MacBook-Pro:bin pcolsen$ java -cp jscheme.jar -jar abcl-1.0.0.jar Armed Bear Common Lisp 1.0.0 Java 1.6.0_29 Apple Inc.

Please feel free to tell me to RTFM, but please give me a hint about what part of TFM I should R. Thanks! Peter Peter Olsen pcolsen(a)gmail.com Scientists study the world; engineers change it.

[armedbear-devel] stack overflow when compiling alexandria-tests
by Anton Vodonosov 20 Dec '11

20 Dec '11

Hello I am running tests of some libraries with ABCL (I decided to setup an test environment for CL libraries). When compiling alexandria tests by (quicklisp:quickload :alexandria-tests) it encounters StackOverflow. I am using the latest quicklisp. I've tried to increase the java stack size by -XX:ThreadStackSize=12048, but it doesn't help. Best regards, - Anton

[armedbear-devel] Bug in reader case handling
by Blake McBride 12 Dec '11

12 Dec '11

Greetings, Given a file name ff.lisp containing the following: (setf (readtable-case *readtable*) :invert) (defpackage "abc" (:use "COMMON-LISP") (:export "MYFUN")) (in-package "abc") (defun myfun (a b) (+ a b)) ; EOF Then try: (use-package "abc") (myfun 4 5) (abc:myfun 4 5) ; this should not work (ABC:myfun 4 5) ; this should work This works as described in sbcl, cmucl, clisp and ecl but doesn't work in abcl. It seams abcl takes into account the case of the entire "ABCL:myfun" when dealing with case. All the other lisps treat "ABC" and "myfun" separately in terms of string case. Blake McBride

[armedbear-devel] FORMAT dollarsign with negative numbers
by Marshall Abrams 05 Dec '11

05 Dec '11

It looks as if there's a bug in 1.0.0 with FORMAT's dollarsign directive's handling of negative numbers when it has to round up. (Forgive me if this is a known issue--I didn't find it when I searched the bug list and mailing list archives--or if there's something I'm misunderstanding.) The first group of examples use the F directive for comparison to show that the problem seems to be specific to dollarsign. (I added blank lines between example groups for easy reading.) The second group of examples illustrates a problem using dollarsign with negative numbers. The output is about 10x too large, and doesn't seem to be getting rounded properly. I'm guessing that the out of bounds error is the result of the same issue. The third group of examples shows that the problem doesn't seem to occur with positive numbers, although there's still an extra negative sign preprended.

[armedbear-devel] [Patch] implement mop:extract-specializer-names
by Rudolf Schlatte 05 Dec '11

... as specified in AMOP page 189. The internal function extract-specializers did exactly the same, so the attached patch renames and exports it. Cheers, Rudi
