From 084b602d9a52b62a04d17f65ba1a9b8a767d1e3e Mon Sep 17 00:00:00 2001 From: tmm1 Date: Tue, 3 Dec 2013 08:11:07 +0000 Subject: * include/ruby/ruby.h (struct RClass): Add wrapper struct around RClass->m_tbl with serial. This prevents double marking method tables, since many classes/modules can share the same method table. This improves minor mark time in a large application by 30%. * internal.h (struct method_table_wrapper): Define new wrapper struct with additional serial. * internal.h (RCLASS_M_TBL_INIT): New macro for initializing method table wrapper and st_table. * method.h (void rb_sweep_method_entry): Rename rb_free_m_table to rb_free_m_tbl for consistentcy * .gdbinit (define rb_method_entry): Update rb_method_entry gdb helper for new method table structure. * class.c: Use RCLASS_M_TBL_WRAPPER and RCLASS_M_TBL_INIT macros. * class.c (rb_include_class_new): Share WRAPPER between module and iclass, so serial can prevent double marking. * eval.c (rb_prepend_module): ditto. * eval.c (rb_using_refinement): ditto. * gc.c: Mark and free new wrapper struct. * gc.c (obj_memsize_of): Count size of additional wrapper struct. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43973 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- eval.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'eval.c') diff --git a/eval.c b/eval.c index f3275ada0b..873d549739 100644 --- a/eval.c +++ b/eval.c @@ -1119,7 +1119,8 @@ rb_using_refinement(NODE *cref, VALUE klass, VALUE module) c = iclass = rb_include_class_new(module, superclass); RCLASS_REFINED_CLASS(c) = klass; - RCLASS_M_TBL(OBJ_WB_UNPROTECT(c)) = RCLASS_M_TBL(OBJ_WB_UNPROTECT(module)); + RCLASS_M_TBL_WRAPPER(OBJ_WB_UNPROTECT(c)) = + RCLASS_M_TBL_WRAPPER(OBJ_WB_UNPROTECT(module)); module = RCLASS_SUPER(module); while (module && module != klass) { -- cgit v1.2.3
