[armedbear-devel] Wrong symbol after loading fasl
by James M. Lawrence 12 Jul '12

12 Jul '12

(defpackage :foo (:use :cl)) (in-package :foo) (defvar *data* nil) (defpackage :bar (:use :cl)) (in-package :bar) (eval-when (:compile-toplevel) (import 'foo::*data*)) (setf *data* 99) Compile this, restart ABCL, and load the fasl. foo::*data* is NIL and bar::*data* is 99. It's possible the code is somehow nonconforming, however it sure seems that foo::*data* should be written and later loaded, which is the behavior of other Lisps. The issue is also exhibited with (compile-file "test.lisp") (delete-package :foo) (delete-package :bar) (load "test.abcl")

Hi folks, The function threads:mailbox-send seems not working. In the example below, (threads:mailbox-peek mbox) returns NIL. It should be "item". The attatched patch fixes this problem.

Don't know if this is fixed in a later version, but I was noticing asdf put my binaries in an odd-looking directory. -Alan

[armedbear-devel] Does ABCL reload abcl.jar after it starts up?
by Marshall 21 Jun '12

21 Jun '12

I have a quick (I hope) question. Does ABCL reload abcl.jar after it starts up? Or do something else unusual with the jar once it's running? Context: I'm exploring using ABCL as an add-on to NetLogo, an agent-based modeling environment. (It might be more correct to say that I'm using NetLogo as an add-on to ABCL, since the primary code is in Lisp.) With the add-on method, NetLogo "extensions", one usually doesn't have to tell NetLogo where additional jars such as abcl.jar can be found. As long as they're in the extension's own directory, NetLogo will find the extra jars. This is apparently due to a little bit of voodoo that NetLogo engages in. However, in the case of my ABCL extension, NetLogo will load the extension, but then generate an error when I invoke ABCL via Interpreter.evaluate(). The problem is avoided if specify abcl.jar in the classpath explicitly, either on the command line (undesirable for NetLogo), or by adding abcl.jar to the classpath in Java (which works fine--so that's what I'm doing). Just curious about what ABCL is doing--thanks. (The ABCL NetLogo extension is very simple, now that I've figured out the details, and seems to be working beautifully, by the way. I'm surprised that there haven't been some glitches. It just works.) Marshall Abrams mabrams(a)uab.edu

[armedbear-devel] asdf 2.22 released
by Faré 13 Jun '12

13 Jun '12

I am pleased to announce the release of ASDF 2.22. Since previous release 2.21, the changes are as follow: * require is now mapped to the recently defined require-system, not to load-system anymore. * more sensible inheritance semantics for default-component-class, which can be either a class or a class name. (hat tip to Nikodemus) * accept wildcards in directory-files for physical pathnames. (hat tip to Erik Pearson). These changes are few and subtle, but nonetheless significant to those who'd use these features. As usual, developers, please test and enjoy, vendors, please update your implementation or distribution. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Pyramid schemes are illegal.

[armedbear-devel] jfli-abcl revisited
by Alex Mizrahi 12 Jun '12

12 Jun '12

hi Some people mentioned that keeping jfli interface is desirable. Also I've noticed a problem with Ole's version: java array accessor (jref) doesn't do boxing correctly. It isn't a big deal, but I kinda used that functionality, and I have no idea what motivated those changes so I don't know to to fix them correctly. So I went back to original jfli-abcl version by Andras Simon and did minimal amount of changes to make it work with new version. Also there are several conservative improvements. Here it is: https://gist.github.com/2916760#file_jfli.lisp And here's a diff against jfli-abcl.lisp still available on Andras' site: https://gist.github.com/2916760#file_jfli_abcl.diff (This one: http://www.math.bme.hu/~asimon/lisp/jfli-abcl.tar ) Here's a description of changes: 1. make-immediate-object is deprecated now, so we use java:+null+ and friends 2. boxing extension by A. Vodonosov is described in comment 3. ensure-java-class was renamed to %ensure-java-class to avoid collision with java:ensure-java-class which does completely different thing. (I thought about shadowing it, but I think renaming makes it clearer.) 4. support for both int and long in overloads (or however they are called in Java) 5. new-class functionality was commented out because abcl-side interface have changed. (together with its helper jrc) As I understand, Alessio already reimplemented jnew-runtime-class, so we just need some brave soul to adapt code to new APi and implement missing parts This isn't particularly hard, I think, but I'm not interested in new-class at all, so I wouldn't do this. And for the sake of completeness here's diff between original jfli-abcl and Ole's version: https://gist.github.com/2916945 It seems that the major difference is "Ripped out CLOS mirror support". I have no idea if 'CLOS mirror support' is required according to jfli spec or it is useless. Also there is a lot of refactoring. Which is great, but it can break things... So again, unless somebody has resources to check Ole's changes and verify that they adhere to jfli documentation, I recommend replacing it with my 'conservative' version in ABCL's contrib repo. Also, I've noticed that jfli maintainer said it would be cool to merge different versions, but I don't think it's necessary: the only common part is defpackage, pretty much all the code is specific to ABCL. (This was true for old jfli version, at least.) So it's better to treat jfli as a specification rather than as a library.

[armedbear-devel] Figuring out the provenance of trunk
by Mark Evenson 11 Jun '12

11 Jun '12

Over the course of maintaining the Bear, it has become clear to me that we have pieces of code in trunk whose original licensing terms indicate that their author should be contacted as to their status, especially when they would conflict with the terms we distribute under, namely those of the GNU Public License. Recently I discovered such a licensing lacunae [in working with Jorge Tavares to patch the CL:SORT and CL:STABLE-SORT routines][1], that 'sort.lisp' contains code that has both SBCL and ECL code attributions. Are we in violation of anything here? Dunno. But we certainly have *lots* of SBCL tucked into our tree… We obviously need an estimate of our non-compliance. As a first step, it seems useful to construct/use a tool that allows us to establish provenance of all commits to ABCL trunk. With this history in hand, we can start figuring out the set of all authors to work through potential conflicts. A fair amount of work for a non-specialist, but anyone who does this regularly should have an analysis toolset lying around that they could apply to [ABCL trunk][2]. Is there a language lawyer geek in the house?
