#69: Gray stream compatibility ---------------------------+------------------------------------------------ Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: compatibility | ---------------------------+------------------------------------------------ The last thing holding us back from being fully Gray stream compatible, is that TYPEP should return T for any fundamental-stream derived instance when tested against 'STREAM or (find-class 'STREAM). -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/69> armedbear <http://common-lisp.net/project/armedbear> armedbear

#125: Qi loading issues ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: libraries | Version: 0.24 Keywords: | ------------------------+--------------------------------------------------- Greg Baryza writes: {{{ I recently became interested in the language QI. Since it did not run on ABCL (it does on SBCL, Allegro, LispWorks and others), I decided to see what it would take to move it there. From the QI mailing list, I found several others had tried on earlier versions of ABCL with inconclusive results. I decided to give it a try on 0.23.1. When I tried the standard script with compiles and then loads the compiled files, ABCL hangs it what appears to be an infinite loop try to load one of the compiled files. When I switch to just loading them in as Lisp sources, things seem to work (though some of the QI tests later fail). I tried the compile/load script under 0.24.0 today and the same hang happens. }}} -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/125> armedbear <http://common-lisp.net/project/armedbear> armedbear

#119: Unexpected CLOS shared slot initialization order --------------------------------------+------------------------------------- Reporter: mevenson | Owner: analysis Type: defect | Status: new Priority: major | Milestone: unscheduled Component: CLOS | Version: 1.0 Keywords: clos unexpected-behavior | --------------------------------------+------------------------------------- Didier Verner writes: {{{ it seems that until now, I've been relying on a non-standard behavior, namely the fact that shared slots with an :initform are initialized before the first actual class instance is created: (defclass test () ((slot :allocation :class :initform t))) (defmethod initialize-instance :before ((test test) &key) (format t "Slot boundp: ~A~%" (slot-boundp test 'slot))) CL-USER> (make-instance 'test) Slot boundp: NIL #<TEST {C5D3B8}> CL-USER> (make-instance 'test) Slot boundp: T #<TEST {14563D4}> CL-USER> I just fell on this because every other Common Lisp implementation I've tried gives T and T here. Is it due to the way CLOS is implemented in ABCL, and is there a chance that this can be improved? }}} -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/119> armedbear <http://common-lisp.net/project/armedbear> armedbear

[armedbear-ticket] [armedbear] #18: Incorporate 'invoke.lisp' dynamic classpath ability

#18: Incorporate 'invoke.lisp' dynamic classpath ability -------------------------+-------------------------------------------------- Reporter: mevenson | Owner: somebody Type: enhancement | Status: new Priority: minor | Milestone: Component: component1 | Version: Keywords: | -------------------------+-------------------------------------------------- Alan Ruttenberg's [invoke.lisp][1] has the ability to easily add additional Java JARs at runtime by using the [beanshell classloader][2]. With a few additions to the ASDF system, this allows one to easily specify "wrappings" of Java components which load JARs or find classfiles on the filesystem. The code in the Beanshell classmanager could be added to the ABCL src tree fairly easily to facilitate this behavior.

#109: When TPL::REPL is unavailable, the debugger kills the entire application ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: libraries | Version: Keywords: | ------------------------+--------------------------------------------------- Ole Myren Rohne reports: "" I'm playing with AbclScriptEngine (with Electric VLSI) and found a tiny problem with config.lisp: EXT:MAKE-THREAD should be THREADS:MAKE-THREAD. "" which is already solved, but continues: Unfortunately the problem was unnecessary hard to debug because in the absence of TPL::REPL the debugger ends up quitting the entire application. I'm wondering if in that case it would be more useful to throw a Java error, eg like SYS::%DEBUGGER-HOOK-FUNCTION?
