When finding reference from [Old obj] to [New obj] by WB, current implementation marks [Old obj] as remembered old objects and marks chilldren of [Old obj] at the beggining of marking. Added (but disabled) code changes current behaviour. This fix promote [New obj] to old and marks as a remembered old object. We can assume "new objects referred from old objects are maybe long-lived old objects". Disadvantage of added algorithm is we may promote unwilling short-lived objects. For example, consider many new objects push and pop to an old stack object. All of new objects (short-lived objects) promote to old objects unexpectedly. To compare these behaviour, I add this new code (but disabled it). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50006 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* * internal.h: remove struct method_table_wrapper.ko12015-03-051-29/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct method_table_wrapper was introduced to avoid duplicate marking for method tables. For example, `module M1; def foo; end; end` make one method table (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl. Classes C1 and C2 includes M1, then two T_ICLASS objects are created and they points mtbl too. In this case, three objects (one T_MODULE and two T_ICLASS objects) points same mtbl. On marking phase, these three objects mark same mtbl. To avoid such duplication, struct method_table_wrapper was introduced. However, created two T_ICLASS objects have same or shorter lifetime than M1 (T_MODULE) object. So that we only need to mark mtbl from M1, not from T_ICLASS objects. This patch tries marking only from M1. Note that one `Module#prepend` call creates two T_ICLASS objects. One for refering to a prepending Module object, same as `Module#include`. We don't nedd to care this T_ICLASS. One for moving original mtbl from a prepending class. We need to mark such mtbl from this T_ICLASS object. To mark the mtbl, we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended class `klass`. * class.c: ditto. * eval.c (rb_using_refinement): ditto. * gc.c: ditto. * include/ruby/ruby.h: define m_tbl directly. The definition of struct RClass should be moved to (srcdir)/internal.h. * method.h: remove decl of rb_free_m_tbl_wrapper(). * object.c: use RCLASS_M_TBL() directly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49862 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | force firnalizations at the end of interpreter process. [Bug #10768] 1) Prohibit incremental GC while running Ruby-level finalizers to avoid any danger. 2) Prohibit GC while invoking T_DATA/T_FILE data structure because these operations break object relations consistency. This patch can introduce another memory consuming issue because Ruby-level finalizers can run after (2), GC is disabled. However, basically object consistency was broken at (2) as I described above. So that running Ruby-level finalizers contains danger originally. Because of this point, I need to suggest to remove these 3 lines (invoking remaining finalizers). And add a rule to add that finalizers should not add new finalizers, or say there is no guarantee to invoke finalizers that added by another finalizer. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49684 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
