ASDF 3.1.7 has been released
by Robert P. Goldman 23 Mar '16

23 Mar '16

ASDF 3.1.7 is a bugfix release, enhancing the 3.1.x ASDF series. To the best of our knowledge, it only fixes bugs, and should thus be a low-risk upgrade for inclusion in implementations. Thanks, as ever, to Faré for many fixes, and to other bug reporters and patch-suppliers. See the Changelog (below) for a summary of changes. Bug fix and portability release: * Fix compilation on Genera. * Fix UIOP:FILE-EXISTS-P for dotfiles on CCL. * Fix infinite loop in source registry configuration that can occur when there are cycles in the filesystem (typically caused by symlinks) on some CL implementations. * Miscellaneous bug fixes. * Documentation improvements. * Restore original Makefile. -- Robert P.

Syntactic sugar to call Java from ABCL?
by EGarrulo 06 Mar '16

06 Mar '16

Hello ABCL developers, has anybody written some macros to make calling Java from ABCL more straightforward? I mean something that, instead of this code from the ABCL documentation: (defun void-function (param) (let* ((class (jclass "Main")) (intclass (jclass "int")) (method (jmethod class "addTwoNumbers" intclass intclass)) (result (jcall method param 2 4))) (format t "in void-function, result of calling addTwoNumbers(2, 4): ~a~%" result))) would let you write something like this, for example: (format t "in void-function, result of calling addTwoNumbers(2, 4): ~a~%" ;; Let's imagine that we have defined a -> macro. (-> |Main.addTwoNumbers| 2 4) Thank you.

Debugging ANSI tests
by Alessio Stalla 07 Feb '16

07 Feb '16

Hi list, in my local copy of ABCL I broke some ANSI tests related to packages and that's not good. I'm lazy so I'm asking here: does someone have a ready recipe to debug the ANSI tests, in particular to place breakpoints inside ABCL's Java code while it is executing the tests? In the minute or so I spent thinking about it before getting lazy, I couldn't figure out how to pass the jdwp incantation to the JVM launched by Ant when testing. Thanks is advance! Alessio

Load abcl
by Hernan Ezequiel Di Giorgi 31 Jan '16

31 Jan '16

The result of cl:compile, how can be loaded via java using .getResourceAsStream()? I'm compiling all the dependencies of a proyect and generating a super abcl.jar with my project inside, in the root directory of the abcl.jar i have a "system.abcl", that can be loaded with cl:load only with it outside the jar. If i try to load if from the jar with the full path "jar:file:/path/abcl.jar!/system.abcl" the repl simply freezes, and do nothing (via java or repl). The org.armedbear.lisp.load.load() throws an exception because don't load the .abcl. The abcl is generated with (asdf:operate 'asdf:monolithic-compile-boundle-op system-name). I just can't use the .abcl when is inside the jar. Any ideas??

Loops and interruptibility
by Scott L. Burson 31 Dec '15

31 Dec '15

Hi all, The other day I had an inadvertent infinite loop in my code, running in ABCL, and found I was unable to interrupt it with double C-c in SLIME. In fact, even when I killed the process, restarted it, and started the code with the infinite loop in a new thread, I couldn't kill the thread! Is this a known problem, or is something wrong with my setup? -- Scott

Problems with static methods (and interface implementation?), java.lang.NoClassDefFoundError.
by fsmunoz＠gmail.com 28 Dec '15

28 Dec '15

Hello, I have been struggling with this for some hours now and would welcome some pointers. I'm writing a small how-to on how to deploy Common Lisp web applications (i.e. "something that replies to an HTTP request") in IBM's Bluemix using ABCL. That part is taken care of and I have it up and running (more on that in a separate post). I was going for a more advanced version and I am having a problem with interface implementation. To showcase java interop I am not using CL web frameworks, but decided to give Spark a try (http://sparkjava.com/documentation.html) just to get a minimal example up and running (I already have Jetty working and serving up an "(Hello World)" page): #+BEGIN_SRC java import static spark.Spark.*; public class HelloWorld { public static void main(String[] args) { get("/hello", (req, res) -> "Hello World"); } } #+END_SRC I'm going to start with the Clojure example since that one I got working; the API reference (http://spark.screenisland.com/spark/Spark.html) helped me and this works #+BEGIN_SRC clojure => (Spark/get "/hello" (reify spark.Route (handle [this req res] ("Hello World")))) [Thread-34] INFO spark.webserver.JettySparkServer - == Spark has ignited ... [Thread-34] INFO spark.webserver.JettySparkServer - >> Listening on 0.0.0.0:4567 nil[Thread-34] INFO org.eclipse.jetty.server.Server - jetty-9.3.2.v20150730 #+END_SRC I have learned (thanks to bpalmer in #emacs, cheers!) that the Single Abstract Method can be constructed using Java 8 lambda expressions, which is why I couldn't find a reference to the "handle" method, which I got from the API. Now, back to ABCL; I'm unable to reproduce the above and I'm unsure if it is because I'm not getting something right (likely) or because some of the plumbing in ABCL isn't quite there yet. I tried this using jss::jinterface-implementation (which I had used previously with my MQTT code and worked perfectly): #+BEGIN_SRC lisp (#"get" 'spark.Spark "/hello" (jss::jinterface-implementation "spark.Route" "handle" (lambda (request response) ("Hello World")))) #+END_SRC The (jinterface-implementation ...) returns #<com.sun.proxy.$Proxy5 com.sun.proxy.$Proxy5@4f0bbf2a {41CC48BB}>, but the (#"get"...) fails: Java exception 'java.lang.NoClassDefFoundError: Could not initialize class spark.Spark$SingletonHolder'. I have also tried with jmake-proxy to see if there was something different going on. #+BEGIN_SRC lisp (java::jstatic "get" "spark.Spark" "/hello" (java::jmake-proxy "spark.Route" #'(lambda (lisp-this method request response) ("Hello World")))) #+END_SRC The result is the same, both in what jmake-proxy returns and the final error. Note that I have added the jar to the classpath, otherwise I would get "ClassNotFound". Even more simply this also doesn't work: #+BEGIN_SRC clojure => (Spark/stop) [nREPL-worker-11] INFO spark.webserver.JettySparkServer - >>> Spark shutting down ... #+END_SRC ... (#"stop" 'spark.Spark) returns the same "NoClassDefFoundError", which makes me thing the issue is not with the jproxy bit but something more fundamental... With this in mind: 1) Is there anything obviously wrong about the way I'm going about it - not limited to implementation errors on my part but including trying to use parts of ABCL's Java interop which aren't done? 2) The java::jmake-proxy call... I wasn't able to find a single example of it used (the only code I find when searching is the implementation itself) so I'm not sure I'm understanding the documentation correctly: are the arguments I'm using above correct? I'm using the method that uses a function and if I understood it correctly the first argument is "lisp-this" (which defaults to nil), the second the method name (which would be "handle" in this example, and the rest are the method arguments (request and response here). I am of course available for any further clarification, and if this is something that isn't obvious I can upload a minimal example using quickproject and quicklisp.

ASDF configuration for "JAR-only" system
by John Pallister 16 Dec '15

16 Dec '15

Hello list, I'm trying to configure ASDF to load my application while running within the Google App Engine development server (Jetty 6.1). My Ant build script uses ASDF-JAR:PACKAGE to produce a single JAR file containing my application and all dependencies, and copies this to the war/WEB-INF/lib/ directory so that it's in the classpath. At runtime (in a separate bootstrap.lisp file), following the example of ASDF-JAR:ADD-TO-ASDF[1], I search the application JAR file (obtained by grovelling JAVA:DUMP-CLASSPATH) for the .ASD files and push them all onto ASDF:*CENTRAL-REGISTRY*. So far so good. (Having read the ASDF manual I now know I should either build a .cl-source-registry.cache file into the JAR or compute an ASDF source registry configuration and include that.) When ASDF starts up it tries to read various configuration files from the filesystem, for both the source registry and for its output translations. This isn't allowed by App Engine. On #lisp, Attila Lendvai suggested that giving ASDF a source registry configuration of '(:SOURCE-REGISTRY :IGNORE-INHERITED-CONFIGURATION) should suppress this behaviour, and it does seem to work. Now I'm struggling to get the output translations to work. Based on ADD-TO-ASDF again I'm using an output translations configuration of: `(:output-translations (,(merge-pathnames "/**/*.*" *application-jar-path*)) ; => #P"/**/*.*" :ignore-inherited-configuration :disable-cache) My *APPLICATION-JAR-PATH* is #P"jar:file:/Volumes/SoftRAID/Users/john/src/synchromesh/forumfeedme/war/WEB-INF/lib/forumfeedme-lisp-0.1.0.jar!/", i.e. a pathname with the JAR path as the PATHNAME-DEVICE. With this I get the error "access denied ("java.io.FilePermission" "/___jar___file___root___" "read")". This matches the default translations seen in asdf.lisp:WRAPPING-OUTPUT-TRANSLATIONS: (defun wrapping-output-translations () `(:output-translations ;; Some implementations have precompiled ASDF systems, ;; so we must disable translations for implementation paths. #+(or #|clozure|# ecl mkcl sbcl) ,@(let ((h (resolve-symlinks* (lisp-implementation-directory)))) (when h `(((,h ,*wild-path*) ())))) #+mkcl (,(translate-logical-pathname "CONTRIB:") ()) ;; All-import, here is where we want user stuff to be: :inherit-configuration ;; These are for convenience, and can be overridden by the user: #+abcl (#p"/___jar___file___root___/**/*.*" (:user-cache #p"**/*.*")) #+abcl (#p"jar:file:/**/*.jar!/**/*.*" (:function translate-jar-pathname)) ;; We enable the user cache by default, and here is the place we do: :enable-user-cache)) Although I don't understand exactly how the "JAR file as device" (JFAD) translations are supposed to work, one thing that struck me as odd while investigating things was this: CL-USER> (make-pathname :device (list #P"/foo.jar")) #P"jar:file:/foo.jar!/" CL-USER> (merge-pathnames "**/*.*" *) #P"jar:file:/foo.jar!/**/*.*" CL-USER> (merge-pathnames "/**/*.*" **) #P"/**/*.*" CL-USER> (pathname-directory **) (:RELATIVE :WILD-INFERIORS) CL-USER> (pathname-directory **) (:ABSOLUTE :WILD-INFERIORS) That is, merging a relative path with the (absolute) JFAD path retained the default JAR file "device" (and remains a relative path, which ASDF won't accept), but merging an absolute path reset the device component. I've read through the documentation for MERGE-PATHNAMES in the HyperSpec[2] and AFAICT the device component should be copied across. I'm reasonably confident that if it were, things would work better. But I could be (doubly) wrong. I am trying to figure this out for myself, but I'm stuck for now, so I'm hoping someone (i.e. Mark) can, on reading this, offer some guidance as to where I should go from here. I haven't (yet) tried posting to the ASDF mailing list as this seems like a fairly ABCL-specific issue. I guess the fallback is to unpack the application JAR and just load the FASLs directly, but (based again on ADD-TO-ASDF) I'm pretty sure that this should work, and it does seem to be the Right Thing. Any or all comments and/or advice appreciated, Cheers, John :^P [1] http://abcl.org/trac/browser/trunk/abcl/contrib/asdf-jar/asdf-jar.lisp [2] http://www.lispworks.com/documentation/HyperSpec/Body/f_merge_.htm#merge-pa… -- John Pallister john(a)johnp.net john(a)synchromesh.com
