[armedbear-devel] Setup changes for cl-test-grid.cloud.efficito.com
by Erik Huelsmann 08 Apr '15

08 Apr '15

Hi Anton, Looking at some of the test grid failures for ABCL, I noticed some of the OpenGL packages failing due to being unable to locate LibGL.so. To resolve that, I ran: $ aptitude install libgl1-mesa-swx11 Then I noticed something wanted to require JSS, but didn't know how to, so I've added "(require :abcl-contrib)" to /home/testgrid/.abclrc. With these in place cl-glfw-opengl-core seems to load just fine. Any other libraries or measures I should take in order to be able to load (currently failing) systems? Bye, Erik.

[Armedbear-devel] Advancements in preparing ASDF system in ABCL for WAR
by Mark Evenson 06 Mar '15

06 Mar '15

A notice for those interested in my recent work in deploying ABCL as a WAR binary artifact of [an update to abcl-servlet][1], which is where I am collecting my ideas on implementation in an open source form. After locating the ASDF ABCL-SERVLET/BUILD definition, one may CL-USER> (abcl-servlet/prepare :hunchentoot) to create necessary packaging of Hunchentoot and its transitive ASDF dependences to [<file:hunchentoot/build/web/asdf/>][2] for merging into Java Servlet WAR archives. I’ve got a 100 Mib deployment WAR out of this system that has been running in production for six months now, but comments on how to generalise are welcome.

[Armedbear-devel] Tail recursion
by Ralf Moeller 06 Mar '15

06 Mar '15

Hi all, ABCL does not seem to support tail call optimization right now. Are there any plans to provide this?

[Armedbear-devel] Question about pipes
by Sistemas 27 Sep '14

27 Sep '14

Hi: I'm trying to start some processes and connect them using pipes with ABCL (like Unix shell pipes). I've reviewed the documentation but I haven't found anything. Are I missing something? If not, are there any plans of adding input, output and error parameters for run-program (like SBCL, CCL, etc.)? Greets and thanks in advance. Rafael J.

[Armedbear-devel] Comments on Cyrus's proposal for JSS static calls
by Mark Evenson 27 Sep '14

27 Sep '14

Erik asked me to comment on [Cyrus’s proposed patch][1] to extend JSS’s SHARPSIGN-DOUBLE-QUOTE use in static method calls to accept a string as well as a symbol to designate the object. Unfortunately, changing JSS in the manner means that one can no longer use SHARPSIGN-DOUBE-QUOTE on object descended from java.lang.String, for the reasons described in the [JSS README][2]: […] Static calls are possible as well with the #" macro, but the first argument MUST BE A SYMBOL to distinguish (#"getProperties" "java.lang.System") from (#"getProperties" 'java.lang.System) The first attempts to call a method on the java.lang.String object with the contents "java.lang.System", which results in an error, while the second invokes the static java.lang.System.getProperties() method. […] Other than perhaps for aesthetic reasons, is there some functionality that using strings enables here? To argue about preserving character case in strings as opposed to the case folding implicit in symbols doesn’t seem to be applicable, because JSS currently ignores case when searching for matching JVM symbols. In 2006, when I first understood the ignoring case bit of JSS, I was a bit worried that there would be cases where this resulted in ambiguity and errors, but in the ensuing years I have yet to run into a single problem with this design decision. Therefore, I am not currently persuaded that introducing an asymmetry to SHARPSIGN-DOUBLE-QUOTE (“It works on any java Object except those which descend from java.lang.String; for those instances you have to use the JFI”) to use strings as well as symbols to specify static methods is worth it. But please argue back if you disagree… [1]: https://github.com/slyrus/abcl/commit/9ec0fb26c7b7e9470349b1c4bd9be6fa4b053… [2]: http://abcl.org/trac/browser/trunk/abcl/contrib/jss/README.markdown#L55 -- "A screaming comes across the sky.

Re: [Cffi-devel] Patches to CFFI for ABCL which passes all tests

Always something further to fix… Yes, I’ve run across this too. The first https call hangs, even if one adds :connection-timeout 120. Could we be improperly initializing something somewhere along the run? After recovering from this error, subsequent calls work. This is probably more of a cl+ssl issue than a cffi (or ABCL) issue, but it definitely seems to be ABCL-specific. Thanks for your work to clean up the CFFI patch set! I look forward to the day when I can run stock CFFI, cl+ss, and ABCL and have all my code working :) Cyrus
