Was ABCL 1.9.1's source tarball re-uploaded?
by Ruoyu Zhong 22 Mar '23

22 Mar '23

Dear ABCL maintainers, I am a maintainer for the Homebrew package manager. Recently we noticed that the checksum of ABCL 1.9.1’s source tarball, downloaded from https://abcl.org/releases/1.9.1/abcl-src-1.9.1.tar.gz, has changed from 9dc2fb0886e97be1906e6d0a96671ef9d0f52b9f91817e4c64741cd18bf8e0d1 (as of 2023-02-20 10:19 UTC) to a5bc677c9441f4a833c20a541bddd16fff9264846691de9a1daf6699f8ff11e2. May I confirm if the source tarball was updated? Thanks! Regards, Ruoyu

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 16th European Lisp Symposium In-Cooperation-With: ACM SIGLAN Call for Participation April 24-25, 2023 Startup Village, Amsterdam, Nederlands https://www.european-lisp-symposium.org/2023 Sponsored by EPITA, DIRO, MLPrograms, Franz Inc., and SISCOG ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Recent News ~~~~~~~~~~~ Registrations are now open (early bird deadline: April 9) Keynote speakers announced (see below) Important Dates ~~~~~~~~~~~~~~~ - Author notification: March 26, 2023 - Final papers due: April 9, 2023 - Early registration deadline: April 9, 2023 - Symposium: April 24-25, 2023 Scope ~~~~~ The European Lisp Symposium is a premier forum for the discussion and dissemination of all aspects of design, implementation, and application of any of the Lisp dialects, including Common Lisp, Scheme, Emacs Lisp, Clojure, Racket, ACL2, AutoLisp, ISLISP, Dylan, SKILL, Hy, Shen, Carp, Janet, uLisp, Picolisp, Gamelisp, TXR, and so on. We encourage everyone interested in Lisp to participate. The 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 Keynotes ~~~~~~~~ ##### Artificial Intelligence: a Problem of Plumbing? -- Gerald J. Sussman, MIT CSAIL, USA We have made amazing progress in the construction and deployment of systems that do work originally thought to require human-like intelligence. On the symbolic side we have world-champion Chess-playing and Go-playing systems. We have deductive systems and algebraic manipulation systems that exceed the capabilities of human mathematicians. We are now observing the rise of connectionist mechanisms that appear to see and hear pretty well, and chatbots that appear to have some impressive linguistic ability. But there is a serious problem. The mechanisms that can distinguish pictures of cats from pictures of dogs have no idea what a cat or a dog is. The chatbots have no idea what they are talking about. The algebraic systems do not understand anything about the real physical world. And no deontic logic system has any idea about feelings and morality. So what is the problem? We generally do not know how to combine systems so that a system that knows how to solve problems of class A and another system that knows how to solve problems of class B can be combined to solve not just problems of class A or class B but can solve problems that require both skills that are needed for problems of class A and skills that are needed for problems of class B. Perhaps this is partly a problem of plumbing. We do not have linguistic structures that facilitate discovering and building combinations. This is a fundamental challenge for the programming-language community. We need appropriate ideas for abstract plumbing fittings that enable this kind of cooperation among disparate mechanisms. For example, why is the amazingly powerful tree exploration mechanism that is used for games not also available, in the same system, to a deductive engine that is being applied to a social interaction problem? I will attempt to elucidate this problem and perhaps point at avenues of attack that we may work on together. ##### Gradual, Multi-Lingual, and Teacher-Centric Programming Education -- Felienne Hermans, Vrije Universiteit Amsterdam, Nederlands (tba) Programme Chair ~~~~~~~~~~~~~~~ Stefan Monnier, DIRO, Université de Montréal, Canada Programme Committee ~~~~~~~~~~~~~~~~~~~ Mark Evenson, not.org, Austria Marco Heisig, Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany Ioanna Dimitriou, Igalia S.L., Germany Robert Smith, HRL Laboratories Mattias Engdegård Marc Feeley, Université de Montréal, Canada Marc Battyani, FractalConcept Alan Ruttenberg, National Center for Ontological Research, USA Nick Levine, Ravenbrook Ltd, UK Ludovic Courtès, Inria, France Matthew Flatt, University of Utah, USA Irène Durand, Université Bordeaux 1, France Jay McCarthy, Brigham Young University, USA Ambrose Bonnaire-Sergeant, Cisco Christopher League, Long Island University, NY, USA Pascal Costanza, Intel, Belgium Christian Queinnec Local Chair ~~~~~~~~~~~ Breanndán Ó Nualláin, Machine Learning Programs, Nederlands -- Resistance is futile.

Fuller details 1 abcl-1.9.1 ════════════ If one has been hesitating about using the latest ABCL because one "never uses a dot oh release", we have now sloughed off abcl-1.9.1 for your appraisal from the depths of a Bear's long winter nap. Now one can use the somewhat less buggy version of the Tenth Edition of Armed Bear Common Lisp, available, as usual, at <https://abcl.org/releases/1.9.1/> or via Maven <https://search.maven.org/artifact/org.abcl/abcl/1.9.1/jar>. 1.1 News ──────── N.b. that when running on openjdk17 and later runtimes, there is quite a bit of necessary fiddling with command line arguments to "open" various modules to the Bear's introspective gaze. For example, see <https://abcl.org/svn/tags/1.9.1/ci/create-abcl-properties.bash> for the switches necessary to use CFFI to successfully run the CL+SSL test suite. As a reward for your patience, we mention the following notable improvements: 1.1.1 CFFI compatibility ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ We improved the compiler to use wide indices for stack frame locals for the ALOAD, ASTORE, ILOAD, ISTORE, LLOAD, and LSTORE opcodes, which among other goodness, allows CFFI-TESTS to compile again. In addition, we have updated the jar artifact used by CFFI to jna-5.12.1 which includes support for native linkage on the Apple Silicon and other exotic architectures. 1.1.2 (Alan Ruttenberg) Ability to discriminate generic function execution on sub-types of MOP:SPECIALIZER ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ Following SBCL, CCL, and ECL, the Bear now accepts subtypes of MOP:SPECIALIZER as a generic function discriminator. 1.1.3 Overhauled relationship to later openjdk threading models ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ Going back to the future of the original green thread models, recent openjdk releases have started offering lightweight threading implementations. For the Bear, the ability to spawn virtual threads is indicated by the presence of :VIRTUAL-THREADS in CL:*FEATURES*. Setting the special THREADS:*THREADING-MODEL* to :VIRTUAL results in THREADS:MAKE-THREADS spawning virtual threads. On some openjdks one may have to pass a command-line switch the JVM to enable virtual threading. 1.1.4 (Uthar) Implement array types for JAVA:JNEW-RUNTIME-CLASS ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ Support for creating synthetic Java classes at runtime via JAVA:JNEW-RUNTIME-CLASS has been improved by introducing machinery for dealing with array types. 1.1.5 (Alejandrozf) Compiler uses of signals to fallback to interpreted form ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ We fall back to use an interpreted form for compilation results larger than 65535 bytes, which fixes the loading of the FirCAS computer algebra system. 1.1.6 (Alejandrozf) Further fixes to COMPILE-FILE-PATHNAME ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ We have restored the ability to compile Maxima by hopefully untangling the last kinks in the reworking of our COMPILE-FILE-PATHNAME logic. 1.1.7 (Tarn W. Burton) Avoid NIL in simple LOOP from CL:FORMAT directives ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ Simplify simple CL:LOOP requires only compound forms, in the place where returning NIL is neither permitted nor desired. 1.1.8 Broad testing and tweaks across Java Long Term Support (LTS) binaries ╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌ We have extensively tested against recent openjdk8, openjdk11, openjdk17, and openjdk19 binaries. Unfortunately, for openjdk17+ runtimes one needs to pass additional runtime command line switches to the hosting JVM which "open" Java modules to reflective actions. 2 Fuller details ════════════════ More details can be found in <https://abcl.org/svn/tags/1.9.1/CHANGES>.
