| | | | | | | | | | | | | | | | | | | | | | | | | | | * array.c (rb_ary_delete_same_obj): new function for WeakRef. This deletes same objects as item argument in the array. * internal.h (rb_ary_delete_same_obj): add a declaration. * gc.c (wmap_final_func): remove WeakRef object reference from the array. rb_ary_delete() is not usable because it uses rb_equal() to compare object references. * gc.c (wmap_finalize): remove recycled object references from weak map hash properly. How to get object reference from object id was wrong. st_delete() doesn't work properly if key and value arguments are same. The key of obj2wmap is referenced object and the value of obj2wmap is WeakRef array. * gc.c (wmap_aset): obj2wmap should contain WeakRef array in the definition. * test/test_weakref.rb (TestWeakRef#test_not_reference_different_object, TestWeakRef#test_weakref_finalize): add tests for above.
