Subject: [ruby-changes:11559] Ruby:r23192 (trunk): * class.c (rb_define_method_id): use rb_define_notimplement_method_id
akr 2009-04-16 23:17:14 +0900 (Thu, 16 Apr 2009) New Revision: 23192 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=23192 Log: * class.c (rb_define_method_id): use rb_define_notimplement_method_id if rb_f_notimplement is given. (rb_define_protected_method): ditto. (rb_define_private_method): ditto. (rb_define_method): use rb_define_method_id. * include/ruby/intern.h (rb_f_notimplement): declared. (rb_define_notimplement_method_id): declared. * proc.c (method_inspect): show not-implemented. * vm_method.c (notimplement_body): new variable. (rb_notimplement_body_p): new function. (rb_method_boundp): return false if not implemented. (rb_f_notimplement): new function. (rb_define_notimplement_method_id): new function. * process.c (rb_f_fork): use rb_f_notimplement if not implemented. * file.c (rb_file_s_lchmod): use rb_f_notimplement if not implemented.
