[armedbear-ticket] [armedbear] #38: CLOS :metaclass support

#38: CLOS :metaclass support ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: component1 | Version: Keywords: | ------------------------+--------------------------------------------------- Blake McBride reports: Running the code: (defclass meta-class1 (standard-class) (cv1 cv2 cv3) (:metaclass standard-class)) (defclass class1 (standard-object) (iv1 iv2 iv3) (:metaclass meta-class1)) The second object returns: #<STANDARD-CLASS CLASS1 {F673CC}> It should be: #<META-CLASS1 CLASS1 {F673CC}> Not only is it reporting the wrong class of class1 but it doesn't work either. I suppose ABCL doesn't support the :metaclass option. It just ignores it. The problem is that without that option ABCL's CLOS is severely limited. Any plans to fix this? Thanks.

[armedbear-ticket] [armedbear] #45: Support for passing unboxed arguments to local functions

#45: Support for passing unboxed arguments to local functions -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- It would save a great deal of boxing/unboxing, if local functions and self-calling recursive functions could pass and return unboxed values. Although passing unboxed values from the outside world is generally considered 'dependency on implementation details', recursive calls and calls to local functions should be able to depend on this: they get recompiled upon function redefinition anyway. One of the reasons for this ticket: with the improved type-derivations in Jan/Feb 2009, the cl-bench TAK test deteriorated: more boxing was performed. With this change, the (un)boxing can be eliminated, except for the first call (from the outside world). -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/45> armedbear <http://common-lisp.net/project/armedbear> armedbear

#44: Unboxing of local variables with :float and :double representations -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- Currently, variables with :float or :double representations don't get stored unboxed. Since intermediate results of those types do get unboxed, this leads to additional boxing/unboxing. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/44> armedbear <http://common-lisp.net/project/armedbear> armedbear

Something messed up in the Stream ._finishOuput() calls?? -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/48> armedbear <http://common-lisp.net/project/armedbear> armedbear

#72: Faster startup times -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: enhancement | Status: new Priority: major | Milestone: Component: other | Version: Keywords: performance | -------------------------+-------------------------------------------------- Analysis learned that 40% of the execution time spent loading ABCL was spent finding constructors in the Java reflection code. The idea of this issue is to spread the cost of that 40% better over the life time of the application by loading - but not resolving - function classes until they're actually used, by introducing a proxy object of some kind which holds only the byte array of class bytes. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/72> armedbear <http://common-lisp.net/project/armedbear> armedbear

[armedbear-ticket] [armedbear] #64: Caught (general) exceptions not rethrown everywhere

#64: Caught (general) exceptions not rethrown everywhere ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | ------------------------+--------------------------------------------------- The code base uses exceptions derived from ConditionThrowable (Go, Throw, Return) to cause non-local transfers of control. A special exception (ThreadDestroyed) has been derived to cause a jump to the outer-most function in a LispThread. (This doesn't work in the main thread, which isn't enclosed by a function in LispThread like those in other threads.) Some spots in our code seem to discard other exceptions than the ones mentioned above. That's probably wrong in most cases. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/64> armedbear <http://common-lisp.net/project/armedbear> armedbear

Not sure what the best way to support this in ABCL would be. Maybe I should really start mirroring ASDF packages with ABCL-specific patches until we get those patches merged upstream. But then I would like to ABCL's support for ASDF up to current by implementing the long form of CLOS's DEFINE-METHOD-COMBINATION. Chicken, meet egg.
