#239: defgeneric with unsuitable :generic-function-class gives incomprehensible error -----------------------+---------------------------------------------------- Reporter: rschlatte | Owner: ehuelsmann Type: defect | Status: new Priority: minor | Milestone: Component: (A)MOP | Version: Keywords: | -----------------------+---------------------------------------------------- Compiling and loading the following (incorrect) file gives an error saying that foo-generic-function is not of type standard-generic-function. The real error is that foo-generic-function must be defined with (:metaclass funcallable-standard-class) to be suitable as a generic function class. {{{ (require :clos) (defclass foo-generic-function (standard-generic-function)) (defgeneric goo (a b) (:generic-function-class foo-generic-function) (:method (a b) (princ "default method"))) (print #'goo) }}} The attached patch would emit a full warning in defgeneric, but currently find-class does not implement correct behavior when called with 3 parameters. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/239> armedbear <http://common-lisp.net/project/armedbear> armedbear

#242: Unused &key warnings in defmethod forms should not cause style-warnings -----------------------+---------------------------------------------------- Reporter: rschlatte | Owner: ehuelsmann Type: defect | Status: new Priority: minor | Milestone: Component: compiler | Version: Keywords: | -----------------------+---------------------------------------------------- CLHS 7.6.5 says: "The lambda list congruence rules require that each method accept all of the keyword arguments mentioned after &key in the generic function definition, by accepting them explicitly, by specifying &allow-other-keys, or by specifying &rest but not &key." Currently, when compiling a file containing the form {{{(defmethod foo ((x fixnum) &key y z) x)}}} we get style warnings about unused variables y and z. I think that these style warnings can be safely elided, since a typo in the arglist will lead to another style warning "Undefined variable A assumed special". -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/242> armedbear <http://common-lisp.net/project/armedbear> armedbear

Restarts: 0: TOP-LEVEL Return to top level. [1] CL-USER(6): (lisp-implementation-version) "1.1.0-dev-svn-14041" [1] CL-USER(7): The problem is that the defstruct declaration for c "overwrites" the accessor foo-s1 generated by defstruct b. If foo-s1 is called for a b instance, the type assertions introduced by define-reader (and define-writer, see the ABCL implementation for defstruct) cause the error described above. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/231> armedbear <http://common-lisp.net/project/armedbear> armedbear

#211: closure-common fails to load correctly after compilation ---------------------------------------------------------------+------------ Reporter: mevenson | Owner: ehuelsmann Type: defect | Status: new Priority: minor | Milestone: 1.1.0 Component: compiler | Version: 1.1.0-dev Keywords: clos compiler needs-test quicklisp closure-common | ---------------------------------------------------------------+------------ When compiling the fasl for closure-common/ystream.abcl an error in StandardClass.getClassLayout(StandardClass:205) in reading back the parameters. Interestingly, if the system is restarted, the fasl *can* be loaded without complaint, so there seems to be some artifact of the compilation process "hanging around" in memory which causes this problem. Unknown whether this affects the actual us of closure-common This error existed in abcl-1.0.1 as well, so it has nothing to do with the recent work on the MOP. {{{ 0: (#<FUNCTION {50F2A460}> #<TYPE-ERROR {79D34CA}> #<FUNCTION {50F2A460}>) 1: (APPLY #<FUNCTION {50F2A460}> (#<TYPE-ERROR {79D34CA}> #<FUNCTION {50F2A460}>)) 2: (SYSTEM::RUN-HOOK SYSTEM::*INVOKE-DEBUGGER-HOOK* #<TYPE-ERROR {79D34CA}> #<FUNCTION {50F2A460}>) 3: (INVOKE-DEBUGGER #<TYPE-ERROR {79D34CA}>) 4: org.armedbear.lisp.Lisp.error(Lisp.java:379) 5: org.armedbear.lisp.Lisp.type_error(Lisp.java:420) 6: org.armedbear.lisp.Cons.length(Cons.java:240) 7: org.armedbear.lisp.Cons.copyToArray(Cons.java:352) 8: org.armedbear.lisp.LispThread.pprint(LispThread.java:896) 9: org.armedbear.lisp.LispThread.pprint(LispThread.java:916) 10: org.armedbear.lisp.LispThread.pprint(LispThread.java:916) 11: org.armedbear.lisp.LispThread.printBacktrace(LispThread.java:825) 12: org.armedbear.lisp.LispThread.printBacktrace(LispThread.java:807) 13: org.armedbear.lisp.StandardClass.getClassLayout(StandardClass.java:206) 14: org.armedbear.lisp.Layout$6.execute(Layout.java:269) 15: org.armedbear.lisp.Symbol.execute(Symbol.java:802) 16: org.armedbear.lisp.LispThread.execute(LispThread.java:649) 17: org.armedbear.lisp.clos_728.execute(clos.lisp:3470) 18: org.armedbear.lisp.CompiledClosure.execute(CompiledClosure.java:185) 19: org.armedbear.lisp.LispThread.execute(LispThread.java:760) 20: org.armedbear.lisp.Lisp.funcall(Lisp.java:186) 21: org.armedbear.lisp.Primitives$pf_apply.execute(Primitives.java:2817) 22: (SYSTEM:%MAKE-INSTANCES-OBSOLETE #<STANDARD-CLASS RUNES::OCTET-INPUT- STREAM {7F83698F}>) 23: (#<FUNCTION {1455BCD7}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> :DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-STREAMS :TRIVIAL-GRAY-STREAM-MIXIN {7203E3B5}> #<STANDARD-CLASS GRAY-S.. 24: (APPLY #<FUNCTION {1455BCD7}> (#<STANDARD-CLASS RUNES::OCTET-INPUT- STREAM {7F83698F}> :DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY- STREAMS:TRIVIAL-GRAY-STREAM-MIXIN {7203E3B5}> #<STANDARD-CLASS.. 25: (#<STANDARD-GENERIC-FUNCTION REINITIALIZE-INSTANCE {665C1EAE}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> :DIRECT- SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-STREAMS:TRIVIAL-GRAY-STREAM- MI.. 26: (APPLY #<STANDARD-GENERIC-FUNCTION REINITIALIZE-INSTANCE {665C1EAE}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> :DIRECT- SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-STREAMS:TRIVIAL-GRAY-STR.. 27: (#<FUNCTION {5FE63CB6}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> RUNES::OCTET-INPUT-STREAM :DIRECT-SUPERCLASSES (#<STANDARD- CLASS TRIVIAL-GRAY-STREAMS:TRIVIAL-GRAY-STREAM-MIXIN {7203E3B5.. 28: (APPLY #<FUNCTION {5FE63CB6}> (#<STANDARD-CLASS RUNES::OCTET-INPUT- STREAM {7F83698F}> RUNES::OCTET-INPUT-STREAM :DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-STREAMS:TRIVIAL-GRAY-STREAM-MIXIN {7.. 29: (#<STANDARD-GENERIC-FUNCTION ENSURE-CLASS-USING-CLASS {1A3526CF}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> RUNES::OCTET-INPUT- STREAM :DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-S.. 30: (APPLY #<STANDARD-GENERIC-FUNCTION ENSURE-CLASS-USING-CLASS {1A3526CF}> #<STANDARD-CLASS RUNES::OCTET-INPUT-STREAM {7F83698F}> RUNES ::OCTET-INPUT-STREAM (:DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL.. 31: (SYSTEM:ENSURE-CLASS RUNES::OCTET-INPUT-STREAM :DIRECT-SUPERCLASSES (#<STANDARD-CLASS TRIVIAL-GRAY-STREAMS:TRIVIAL-GRAY-STREAM-MIXIN {7203E3B5}> #<STANDARD-CLASS GRAY-STREAMS:FUNDAMENTAL-BINARY-INPUT-.. }}} -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/211> armedbear <http://common-lisp.net/project/armedbear> armedbear
