#205: JSS logic for resolving methods a little wonky (could use better diagnostics on why resolution has failed) -----------------------------------+---------------------------------------- Reporter: mevenson | Owner: mevenson Type: defect | Status: new Priority: major | Milestone: 1.1.0 Component: libraries | Version: 1.0.1 Keywords: jss method-resolution | -----------------------------------+---------------------------------------- [http://thread.gmane.org/gmane.lisp.armedbear.devel/2252 Jonathan P. Bona is working with Alan Ruttenberg] to port LSW from JSS 1 to JSS 3: {{{ I'm working with Alan Ruttenberg to port LSW from the old version of JSS to the JSS that is now part of abcl-contrib. We've run into the following bug when using with-constant-signature: ; these first two work fine: (#"substring" "some string" 2 4) ; "me" (#"substring" "some string" 2) ; "me string" ; and so does this (with-constant-signature ((substring "substring")) (substring "some string" 2 4)) ; "me" ; but this breaks: (with-constant-signature ((substring "substring")) (substring "some string" 2)) ; Wrong number of arguments for public java.lang.String java.lang.String.substring(int,int): expected 2, got 1 ; [Condition of type PROGRAM-ERROR] A problem seems to be in jss::invoke-find-method, which is finding the two argument version of java.lang.String.substring no matter how many arguments its given: (jss::invoke-find-method "substring" "this is a string" '(1)) ; should return the java.lang.String.substring method with one int arg ; #<method public java.lang.String java.lang.String.substring(int,int)> (jss::invoke-find-method "substring" "this is a string" '(1 2) ) ; #<method public java.lang.String java.lang.String.substring(int,int)> (jss::invoke-find-method "substring" "this is a string" '(1 2 3 4 5 6 7 8) ) ; should be an error ; #<method public java.lang.String java.lang.String.substring(int,int) }}} -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/205> armedbear <http://common-lisp.net/project/armedbear> armedbear
