Pointing out ABCL "extensions" to ANSI-TEST
by Mark Evenson 15 Sep '15

15 Sep '15

Congratulations on getting the divergent ANSI-TEST suite codebases back together in one place, as well as establishing this mailing list. As a Common Lisp implementer who only really started studying the language a decade ago, I have profited immeasurably from figuring out why ABCL fails a given ANSI-TEST while other implementations don't. I would like to point out a few "extensions" to the ANSI-TEST suite that ABCL has added over the years so that other implementations might profit from them and/or that some of the ideas might be included in the ANSI-TEST suite itself. Upon reviewing the implementation of these ideas, parts of me cringe at how my younger self implemented things so I wouldn't necessarily recommend adoption of our code wholesale. 1) ASDF By the nature of how ANSI-TEST loads and runs itself, encapsulation as a "true" ASDF system (i.e. one where all the source is declared) seems a little farfetched. And maybe it is useful to be able to run the suite in places where ASDF is not available, such as when bootstrapping a new implementation. Nevertheless, we put some work into encapsulating the ANSI-SUITE into ASDF to the point that it can be loaded and the tests run that might be of interest. [ABCL defines three ASDF systems][1], namely ANSI-RT, ANSI-COMPILED, and ANSI-INTERPRETED. ANSI-RT encapsulates the regression test framework, while ANSI-COMPILED and ANSI-INTERPETED provide definitions to the point that ASDF:TEST-SYSTEM can run the compiled or interpreted tests respectively. This helps with automation of the tests in ABCL's build mechanism. The one caveat is that one cannot run tests in "parallel" on, say, different versions of your implementation that you are regression testing due to the way that ANSI-TEST uses the filesystem of the ANSI-TEST itself to keep fasls and record state for tests in the course of running the suite. [1]: http://abcl.org/trac/browser/trunk/abcl/abcl.asd#L76 2) ABCL.TEST.ANSI In order to support the necessary shenanigans to make the ANSI-COMPILED and ANSI-INTERPRETED definitions work, we [created a small set of utility routines][2]. CLEAN-TESTS performs the removal of intermediate files that the old Makefile used to do. DO-TESTS-MATCHING will run only those tests whose symbols match a regular expression, which is useful for repeatedly running a subset of tests. [2] http://abcl.org/trac/browser/trunk/abcl/test/lisp/ansi/abcl-ansi.lisp 3) ANSI-TEST error "database" We [created a simple s-expr "database"][4] for recording test failures and then [reporting on the results][3]. ABCL is a unique CL implementation because it is hosted on a JVM for which there are multiple implementations and whose behavior often varies by operating system so running the ANSI-TEST suite has proven to be fairly sensitive to hosting JVM implementation version and operating system. Thus, such a database of regressions has proven to be of special importance to ABCL. That being said, my implementation of this idea is pretty amateurish in hindsight, so I think what is important here is the idea rather than the implementation.

Compiler can generate code it cannot load....
by Patrick Stein 02 Sep '15

02 Sep '15

This is a short program for which the compiler creates a file it cannot load. Save this program to a file, then try: (load (compile-file “this-file.lisp”)) ;;; This program causes the ABCL compiler to generate code it cannot load. ;;; ;;; The code compiles and loads correctly if you do any of the following: ;;; * change BUFSIZE to be 'INTEGER instead of '(INTEGER 0 100) ;;; * delete the INLINE declaration for BUFFER-LENGTH ;;; * delete the FTYPE declaration for BUFFER-LENGTH ;;; * delete the TYPE declaration for NEW-CAPACITY (deftype bufsize () '(integer 0 100)) (declaim (inline buffer-length) (ftype (function () bufsize) buffer-length)) (defun buffer-length () (the bufsize 10)) (defun calculate-new-buffer-length (new-capacity) (declare (type bufsize new-capacity)) (min (buffer-length) new-capacity)) As noted in the comment, it is very finicky. There are at least four ways this code could be slightly less-specific and then not trigger the bug. I tried it both with ABCL-1.3.1 and ABCL-1.3.2. The logs of the output are below. I’d love to be able to say that I’m looking at the compiler now to try to figure out where it’s going wrong, but realistically, I’m not going to have time to delve into it myself, I’ve never really looked at the ABCL compiler before, and I suspect the problem is in the compiling but doesn’t show up until the loading… so it won’t be as easy as exploring the stack when the error shows up. Thanks, Patrick Script started on Tue Sep 1 16:33:56 2015 bash-3.2$ cat compile-problem.lisp ;;; This program causes the ABCL compiler to generate code it cannot load. ;;; ;;; The code compiles and loads correctly if you do any of the following: ;;; * change BUFSIZE to be 'INTEGER instead of '(INTEGER 0 100) ;;; * delete the INLINE declaration for BUFFER-LENGTH ;;; * delete the FTYPE declaration for BUFFER-LENGTH ;;; * delete the TYPE declaration for NEW-CAPACITY (deftype bufsize () '(integer 0 100)) (declaim (inline buffer-length) (ftype (function () bufsize) buffer-length)) (defun buffer-length () (the bufsize 10)) (defun calculate-new-buffer-length (new-capacity) (declare (type bufsize new-capacity)) (min (buffer-length) new-capacity)) bash-3.2$ ABCL_HOME=/usr/local/src/abcl-1.3.2 abcl Armed Bear Common Lisp 1.3.2 Java 1.8.0_45 Oracle Corporation Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.524 seconds.

Better integration between ABCL & Java
by Blake McBride 30 Aug '15

30 Aug '15

Greetings, I worked hard on a project to link ABCL with a very large Java application. Although the addition of ABCL to that project failed, the work I did could be of use, and with some effort could be made to solve the problem I had. I believe the original problem I had would be a very common problem in similar circumstances. My pre-existing Java application has almost 10,000 classes! I wasn't about to create lisp cover functions for each java method. I also wasn't going to use a convoluted syntax to get to java each time. What I did was create some Java and Lisp code that, through reflection, caused the system to auto-generate a complete set of CLOS classes to mirror my primary java application classes - including the class hierarchy. The methods in these CLOS classes would call the Java methods. With this, when in Lisp, I could just use all of my Java classes and methods as regular CLOS classes and methods. It's use of Java classes and methods internally was transparent to lisp. All of this worked fine. The problem I ran into was the fact that Java can have several methods with the same name but different arguments. So, the Java method being called depended on the types and number of arguments too (not just the class of the instance and the method name). I never solved this, although I think it could be. I just ran out of time and steam, as well as other non-technical reasons. The reason I bring this all up now is because I am unclear about what problems Ralph is trying to solve. I thought what I have done may be of use. Thanks. Blake McBride

All conformance ansi-test's passed
by Ralph Ritoch 27 Aug '15

27 Aug '15

Hello, I have been able to get ABCL to pass all of the ansi conformance tests. While this is not an official ABCL release, all of the modifications I made are released under the MIT license and may be freely integrated into ABCL at the discretion of the maintainers. To embed this conforming version into your java applications add the following dependencies which have been released at maven central. <dependency> <groupId>com.vnetpublishing.lisp</groupId> <artifactId>jrelisp-abcl-impl</artifactId> <version>0.0.2</version> </dependency> <dependency> <groupId>com.vnetpublishing.lisp</groupId> <artifactId>jrelisp-abcl-contrib</artifactId> <version>0.0.2</version> </dependency> The source code for this release can be found at https://github.com/rritoch/jrelisp-abcl/tree/55e808d3c0084d16d1ed04c36a6f5a… . While I have moved some files around it is still an ABCL implementation that is mostly backwards-compatible with the official ABCL releases. Moving forward it is likely that any future development on these branches will further deviate from ABCL. I am not claiming that this solves EVERY compliance issue but I have found solutions for each of the ansi conformance test failures. Any remaining compliance issues can be considered a bug. My primary intention of passing every test is to lock the build process so that builds will fail if any of the ansi tests fail. It is unlikely that future modifications to these forks will have any relevance to ABCL. I will likely continue developing features that are needed for modern application development and therefore are of little interest to some, if not all, of the ABCL maintainers. That being said, v0.0.2 is the best release to source conformance solutions from for ABCL as it passes every conformance test. Any future releases will no longer be based on improving ABCL but be for the purpose of better supporting modern application development. Best Regards, Ralph Ritoch

loading lisp files from inside the java jar
by Hamda Binte Ajmal 18 Aug '15

18 Aug '15

Hi, I am sending this message again, as the last thread went a little too far. I have developed a Java Application that runs lisp code at the back end, and I use ABCL for that. Before using the lisp commands, I load a few .lisp files so that I can call the functions defined in those files. Everything works fine as long as I run the application from Netbeans. When I run the application from the jar file, it throws 'File not found error'. as the lisp files are not a part of file system inside the project jar. I tried to follow the suggestions given by Mark (load “jar:file:/absolute/path/to/file.jar!/path/within/jar/setup.lisp”) It shows the same File not found error. Am i missing something here? As suggested by Ralph to use (load-system-file "path/to/resource.lisp"), I tried to use that, but I was unable to access sys package, please let me know how to do this. I find the help documentation and tutorials very confusing, and difficult to understand. Any hints will be appreciated. Thanking in anticipation. Regards, Hamda NUIG, Ireland.

This "idiot" refactored a very small portion of your code making it MUCH faster, and also passed more than 90% of the tests ABCL is currently failing, leaving only 3 ansi-tests that are still failing. If I'm an idiot it doesn't say much about you since you've been working on this for years and I've only been working on it for weeks.

Hi, I was working on an application, that loads a few lisp files using lisp command (load "fullfilepath.lisp") from java using ABCL. This file in turn loads the other lisp files located in same folder hierarchy, and then i call lisp functions (defined in these files) from java and everything works perfect as long as I run the application from Netbeans. Close to deployment, I tested the application by running it from jar file, I found that there are issues with filepaths, as the files are not a part of file-system, and hence not accessible using a file-path. Does anyone has any idea how to fix this issue ? I tried many things, like URL url = LispConnector.class.getResource("/Aima/aima/quicklisp/setup.lisp");String path = url.getFile();File f = new File(path); path = f.getAbsolutePath(); path = path.replace("\\", "/"); which returns [image: enter image description here] But which is wrong as this is not a valid file path and does not exists so lisp : (load "filepath") fails here. When I use the code String path = url.toURI();File = new File(path); path = path.getAbsolutePath(); Again it works fine while running from netbeans, but shows error "URI is not hierarchical" error while running the jar file. Has anyone encountered this issue, please help. -- Hamda Binte Ajmal NUIG, Ireland

Hello, Since you are loading resources and not from the filesystem you probably want to utilize the load-system-file function which I believe is provided by the :sys package. I'm not sure how portable this is so you may want to add some additional control logic if you want portability. (load-system-file "path/to/resource.lisp") Best Regards, Ralph Ritoch On Fri, Aug 14, 2015 at 8:00 PM, <armedbear-devel-request(a)common-lisp.net> wrote: > Send armedbear-devel mailing list submissions to > armedbear-devel(a)common-lisp.net > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.common-lisp.net/listinfo/armedbear-devel > or, via email, send a message with subject or body 'help' to > armedbear-devel-request(a)common-lisp.net > > You can reach the person managing the list at > armedbear-devel-owner(a)common-lisp.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of armedbear-devel digest..." > > > Today's Topics: > > 1.
