[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

#48: SLIME CVS HEAD as of 2008-12-30 broken -------------------------------------+-------------------------------------- Reporter: mevenson | Owner: mevenson Type: defect | Status: new Priority: major | Milestone: 0.13 Component: other | Version: 1.0 Keywords: slime emacs application | -------------------------------------+-------------------------------------- Symptom is the failed listening to SlimeInputStream that doesn't detect a pipe close, therefore never closes, so further enviornment bindings are incorrect. *inferior-lisp* buffers needs to evaluate a form before SLIME works properly. 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

[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

[armedbear-ticket] [armedbear] #54: pprint.lisp incompatible with gray-streams.lisp

#54: pprint.lisp incompatible with gray-streams.lisp ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | ------------------------+--------------------------------------------------- pprint.lisp special-cases the XP-STRUCTURE argument type for the stream argument specified to all the stream functions. Although SBCL uses largely the same approach, it uses a (slightly) different approach, which is important in the details. (Isn't that where the devil usually is?) The difference between ABCL and SBCL is that SBCL - although it uses largely the same structure to store its pprinter values - this structure extends the structure which is used to represent streams. In ABCL, this structure is a structure by itself. To compensate for the fact that the structure isn't recognised as a stream itself, all stream functions special case the XP-STRUCTURE argument handling. Proposed solution: make streams based on dispatch tables stored in structures, just as SBCL does. This way, most of our streams "stuff" can be implemented in Lisp, instead of Java. As a bonus, this issue can be resolved along the same lines as SBCL does. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/54> armedbear <http://common-lisp.net/project/armedbear> armedbear
