From 421314cf4e532cd4b840924b73f73fe33f25647b Mon Sep 17 00:00:00 2001 From: shugo Date: Thu, 29 Nov 2012 12:50:10 +0000 Subject: * vm_method.c (rb_method_entry_make): add a method entry with VM_METHOD_TYPE_REFINED to the class refined by the refinement if the target module is a refinement. When a method entry with VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with the same name is searched in refinements. If such a method is found, the method is invoked. Otherwise, the original method in the refined class (rb_method_definition_t::body.orig_def) is invoked. This change is made to simplify the normal method lookup and to improve the performance of normal method calls. * vm_method.c (EXPR1, search_method, rb_method_entry), vm_eval.c (rb_call0, rb_search_method_entry): do not use refinements for method lookup. * vm_insnhelper.c (vm_call_method): search methods in refinements if ci->me is VM_METHOD_TYPE_REFINED. If the method is called by super (i.e., ci->call == vm_call_super_method), skip the same method entry as the current method to avoid infinite call of the same method. * class.c (include_modules_at): add a refined method entry for each method defined in a module included in a refinement. * class.c (rb_prepend_module): set an empty table to RCLASS_M_TBL(klass) to add refined method entries, because refinements should have priority over prepended modules. * proc.c (mnew): use rb_method_entry_with_refinements() to get a refined method. * test/ruby/test_refinement.rb (test_inline_method_cache): do not skip the test because it should pass successfully. * test/ruby/test_refinement.rb (test_redefine_refined_method): new test for the case a refined method is redefined. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37993 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/ruby/test_refinement.rb | 28 +++++++++++++++++++++++++++- 1 file changed, 27 insertions(+), 1 deletion(-) (limited to 'test/ruby') diff --git a/test/ruby/test_refinement.rb b/test/ruby/test_refinement.rb index 3ca00ed912..3b8a0cd658 100644 --- a/test/ruby/test_refinement.rb +++ b/test/ruby/test_refinement.rb @@ -726,7 +726,6 @@ class TestRefinement < Test::Unit::TestCase end def test_inline_method_cache - skip "can't implement efficiently with the current implementation of refinements" c = InlineMethodCache::C.new f = Proc.new { c.foo } assert_equal("original", f.call) @@ -822,4 +821,31 @@ class TestRefinement < Test::Unit::TestCase end end end + + module RedifineRefinedMethod + class C + def foo + "original" + end + end + + module M + refine C do + def foo + "refined" + end + end + end + + class C + def foo + "redefined" + end + end + end + + def test_redefine_refined_method + c = RedifineRefinedMethod::C.new + assert_equal("refined", RedifineRefinedMethod::M.module_eval { c.foo }) + end end -- cgit v1.2.3
