#67: initarg checking performance -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: CLOS | Version: Keywords: performance | -------------------------+-------------------------------------------------- Our initarg checking strictness has improved (used to be non-existent), but we've seen a rather large performance hit, amongst other things upon object instantiation (make-instance). Functions involved (?): ALLOCATE-INSTANCE INITIALIZE-INSTANCE REINITIALIZE-INSTANCE SHARED-INITIALIZE UPDATE-INSTANCE-FOR-DIFFERENT-CLASS UPDATE-INSTANCE-FOR-REDEFINED-CLASS -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/67> armedbear <http://common-lisp.net/project/armedbear> armedbear

#126: Provide mechanism for user to extend Java classes via Lisp ----------------------+----------------------------------------------------- Reporter: mevenson | Owner: nobody Type: task | Status: new Priority: minor | Milestone: unscheduled Component: java | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- [http://stackoverflow.com/questions/4785969/can-you-write-a-java-class- with-abcl/4803353#4803353 In a question on StackOverflow] a user asks if it is possible to extend a Java class in Lisp. This sort of functionality generally seems to be unavailable in any JVM language, only possible by using bytecode libraries. Since we have a fairly complete bytecode library in our Java class writer, it might provide a distinguishing feature to implement such an extension mechanism. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/126> armedbear <http://common-lisp.net/project/armedbear> armedbear
