Steps to a release

Erik Huelsmann — 2008-10-12T10:45:39

We've made great progress over the last 2 months making ABCL more compliant with the ANSI standard (reducing ANSI tests failures). We've also improved the quality of our build infrastructure a lot, especially the case where people don't have a Lisp handy to bootstrap. That calls for a release to make this fact public :-) I think we need a few steps before we can make the actual release: 1) Describe the changes between 0.0.10 and the new release (0.0.11) 2) We need to verify the tarballs created by our new build.xml file actually can be built either using Ant or using the Lisp way. 3) We need to verify that the tarballs as well as the jars created out of them are "the same" (contain the same files) as a build out of the repository 4) It must be clear what the license for ABCL is, both from our website as well as from the tarball (is it currently?) and after a release, we should probably work on: * documentation on how to get started with ABCL on the website * examples on how to use ABCL from your own Java application Takers?

Sixth iteration of build.xml

Mark Evenson — 2008-10-11T18:08:04

Attached, the sixth iteration of build.xml against common-lisp.net SVN trunk, addressing: o many assorted fixes for builds under win32 (tested without cygwin) o j.install works (except that it doesn't seem to find the documentation) What is left to completely duplicate the behavior of the old build.xml: 1. Figure out J's notion of version, using this to build source distributions 2. Better testing of the J install target (documentation doesn't seem to work: what else?) Diffs to the previous iteration on [abcld][1]. [1]: http://code.google.com/p/abcl-dynamic-install/source/diff?spec=svn163&r=163&format=side&path=/trunk/abcl/build.xml

Assesment of problem in PUSHNEW/PUSH/POP tests

Erik Huelsmann — 2008-10-11T15:08:03

Ville and I were looking into the PUSHNEW/PUSH/POP failures in the ANSI tests. What we found is that the macros don't take an environment variable, yet they do invoke macroexpand to determine macro expansion. The fix is to add an environment variable to the functions. However, it looks like building all of ABCL then breaks with a stack overflow. This morning I found why: In Primitives.java there's a stub implementation of the Lisp ERROR symbol function. It delegates the invocations of its function to the Java Lisp.error() function. However, that function does nothing more than invoke the Lisp ERROR symbol function. As you see, this is a circular reference. I decided to remove the delegation and just print out a stack trace and bail out. There's one remaining question: How to bail out nicely (as we're a library...)? Then, when I print the arguments to the ERROR call and the stack, the real problem becomes visible: In proclaim.lisp, there's a PUSHNEW form which upon macro-expansion claims the ENV variable (which I added to the arglist of PUSHNEW) isn't bound.

Re: Java Scripting API integration for ABCL

Alessio Stalla — 2008-10-09T22:07:00

Well, many thanks Erik! Tomorrow is fine, but there's no hurry :) I'm attaching the source + tests as a zip. The only dependencies are Java 1.6 and ABCL (duh), + JUnit 3 for the tests. The src directory contains, in addition to the .java files, two .lisp files and a META-INF directory: these items need to be included in the compiled jar as well; currently I use Eclipse to build the project, and simply include the abcl jar in the classpath. So the first thing I'll have to investigate is how to integrate it with the ABCL build process. Of course, any help is appreciated ;) Thanks again, Alessio On Thu, Oct 9, 2008 at 11:40 PM, Erik Huelsmann gmail.com> wrote: ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/_______________________________________________ armedbear-j-devel mailing list armedbear-j-devel< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/armedbear-j-devel

Agreed. Ville, Mark, if there are no urgent additions, I plan to commit this patch to the trunk tomorrow after work. I think we can agree that it's a large improvement on what we have. If there are even further improvements to be gained, we can improve upon the committed version again. Agreed?

Re: Test failures for PUSH.5, POP.3 and PUSHNEW.21

Ville Voutilainen — 2008-10-09T19:09:54

IMHO this does not matter, PUSHNEW.20 works and it's not that different. Now I think we're getting closer. I took a look at the setf-expander in this case: CL-USER(4): (GET-SETF-EXPANSION '(EXPAND-IN-CURRENT-ENV (%M X))) (#:G48) (X) (#:G47) (FUNCALL (FUNCTION (SETF %M)) #:G47 #:G48) (%M #:G48) (function (setf..))? Huh? Quoth the hyperspec from http://www.lispworks.com/documentation/HyperSpec/Body/s_fn.htm "Specifically, it is an error to use function on a symbol that denotes a macro or special form." AFAIK setf is just that, a macro or a special form. That's why the test says such a function is undefined, because it isn't a function. I think the next step would be to find out why get-setf-expansion returns such an expander. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/
