disabling debugger in production
by Vibhu Mohindra 26 Apr '17

26 Apr '17

I'm bundling up a program for distribution to customers. I don't want it to ever enter the debugger. I want it to raise Java exceptions instead. What I've written to achieve this follows. I've observed it working. However, there are still times when my program enters the debugger. I can't tell why, and want to prevent it entirely. Does anybody know? Does anyone on this list distribute ABCL applications to end users, and how do you disable the debugger? /* disable the debugger. raise a RuntimeException instead */ static void installDebuggerHook() { Symbol.DEBUGGER_HOOK .setSymbolValue(new Function() { public LispObject execute(LispObject c, LispObject h) { throw translateCondition(c);}}); } static RuntimeException translateCondition(LispObject c) { return new RuntimeException( c instanceof Condition ? String.format("%s: %s", c.princToString(), ((Condition) c).getConditionReport()) : c.princToString()); } My program is really a Lisp library that people will use via a thin Java layer. I have a hunch that the above takes care of errors that occur in: interpreter.eval("...") but not errors that occur in: someSymbol.execute(...) Thanks in advance, Vibhu

sys:run-program errs (both Windows & Linux)
by Mirko Vukovic 14 Jan '17

14 Jan '17

While narrowing down the problems I was having with maven and cffi, I came across the maven-embedded.lisp file ( https://common-lisp.net/svn/armedbear/branches/1.4.0/contrib/abcl-asdf/mave… ) where I saw the sys:run-program. I now have ABCL installed on both Linux and Windows, and have problems on both when issuing #+windows(sys:run-program "where.exe" nil) #+linux(sys:run-program "which" nil) On Windows, the first call fails, while the second succeeds. On Linux, the call fails, and repeated calls also fail. Is this just me or can anyone else reproduce this? Thanks.

IEEE NaN and Infinities
by Antoniotti Marco 08 Jan '17

08 Jan '17

Hi I am fiddling around with IEEE NaN and Infinities. In LW and CCL you have the following conventions for such things: 1d+-0 is NaN (quiet; double float) 1d++0 is positive infinity (double float) Negative infinities are obtained by prepending ‘-‘ to the positive infinities. Other float lengths can be obtained by using the appropriate ’s’, ‘e’, ‘f’, ‘l’. I tried an (APROPOS “NAN”) and an (APROPOS “INFINITY”) in ABCL, but got nothing. Being myself a lazy bastard, I thought of asking directly here instead of looking at the code :) Any possibility of seeing these in ABCL? Apart from that, there is the issue of “rounding modes”. Would it be possible to add them or access them in ABCL?

Failure to load cffi (again): unable to find maven (again)
by Mirko Vukovic 05 Jan '17

05 Jan '17

Earlier today I was able to load cffi by renaming mvn.cmd to mvn.bat. Later on, I am unable to, and I would appreciate a fresh pair of eyes. (ABCL/Java info: C:\Users\977315>java -jar "c:\mv-program-files\abcl-bin-1.4.0\abcl.jar" Armed Bear Common Lisp 1.4.0 Java 1.8.0_112 Oracle Corporation Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.243 seconds. Startup completed in 3.812 seconds. Loading C:\Users\977315\.abclrc completed in 13.729 seconds.) The error seems to happen in abcl-cffi.lisp. mvn.bat is visible: (uiop/run-program:run-program '("where" "mvn.bat") :output :string) gives "C:\\Program Files\\apache-maven-3.3.9\\bin\\mvn.bat " NIL 0 I don't know how to narrow down the search for the culprit. It makes me think that maybe the error message is not correct - that there is a different underlying cause. Is there some direct way I can test maven+aether? I now next to nothing about Java, and looking at abcl-cffi, I did not find anything obvious. Thanks for your help and patience, Backtrace follows.

uiop/run-program:run-program regression after asdf-3.1.7
by Mirko Vukovic 05 Jan '17

05 Jan '17

I try running (uiop/run-program:run-program '("where" "mvn.bat") :output :string) On asdf 3.1.7, it returns the correct output. With asdf 3.1.7.27 and 3.1.7.43. I get an error "Class not found: java.lang.UNIXProcess". If I go to the top level, and try again, I get the correct result. This is with: C:\Users\977315>java -jar "c:\mv-program-files\abcl-bin-1.4.0\abcl.jar" Armed Bear Common Lisp 1.4.0 Java 1.8.0_112 Oracle Corporation Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.238 seconds.

I hope all the problems I am having have one single root cause - and that we discover it :-)

Loading CFFI, I get BAD-SYSTEM-NAME errors related to followed by a huge stack dump, and then debugger related to the Maven executable. I tested this with --noinit. Thanks for your help. Here are more details: Starting ABCL on Windows 10 like so: >/c/Windows/SysWOW64/java.exe -jar /c/mv-program-files/abcl-bin-1.4.0/abcl.jar Armed Bear Common Lisp 1.4.0 Java 1.7.0_51 Oracle Corporation Java HotSpot(TM) Client VM Low-level initialization completed in 0.23 seconds. Now I try to load cffi with quicklisp. Following quickload, I get many style-warnings about redefining UIOP: CL-USER(1): (ql:quickload :cffi) To load "cffi": Load 1 ASDF system: cffi ; Loading "cffi" .................................................. .................................................. .................................................. .................................................. .................................... ; Caught STYLE-WARNING: ; redefining UIOP/PACKAGE:FIND-PACKAGE* in #P"C:/mv-program-files/my-lisp-libraries/asdf/uiop/package.lisp" (previously defined in #P"C:/Users/977315/asdf.3.1.7.43.lisp") ; Caught STYLE-WARNING: ; redefining UIOP/PACKAGE:FIND-SYMBOL* in #P"C:/mv-program-files/my-lisp-libraries/asdf/uiop/package.lisp" (previously defined in #P"C:/Users/977315/asdf.3.1.7.43.lisp") .... many such warnings ... After finishing the style-warning messages, come ASDF load messages, the BAD-SYSTEM-NAME messages, followed by a long java stack dump: Using probed value of abcl-contrib: 'C:/mv-program-files/abcl-bin-1.4.0/abcl-contrib.jar'.

At the end I get into the ABCL debugger: Caused by: org.armedbear.lisp.Go ; Caught SIMPLE-WARNING: ; Unable to locate Maven executable to find Maven Aether adaptors. jnaASDF could not load because Java exception 'java.lang.ClassNotFoundException: com.sun.jna .Native'.. #<THREAD "interpreter" {472108}>: Debugger invoked on condition of type JAVA-EXCEPTION Java exception 'java.lang.ClassNotFoundException: com.sun.jna.Native'.

ELS'17 - 10th European Lisp Symposium VUB - Vrije Universiteit Brussel Belgium April 3-4, 2017 In co-location with <Programming> 2017 Sponsored by Brunner Software GmbH http://www.european-lisp-symposium.org/ The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, Hop and so on. We encourage everyone interested in Lisp to participate. The 10th European Lisp Symposium invites high quality papers about novel research results, insights and lessons learned from practical applications and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. Topics include but are not limited to: - Context-, aspect-, domain-oriented and generative programming - Macro-, reflective-, meta- and/or rule-based development approaches - Language design and implementation - Language integration, inter-operation and deployment - Development methodologies, support and environments - Educational approaches and perspectives - Experience reports and case studies We invite submissions in the following forms: Papers: Technical papers of up to 8 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 2 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. The symposium will also provide slots for lightning talks, to be registered on-site every day. All submissions should be formatted following the ACM SIGS guidelines and include ACM classification categories and terms. For more information on the submission guidelines and the ACM keywords, see: http://www.acm.org/sigs/publications/proceedings-templates and http://www.acm.org/about/class/1998.
