2014-11-13* gc.c: Tuning RincGC parameters.ko1
Before this patch, gc_marks_step() marks (white -> grey) fixed number objects. However, this strategy does not fit practical cases, for example too slow to make progres. This patch changes this strategy how many objects the gc_marks_step() should handle. We can estimate how many times gc_marks_step() is called during this major marking (== C) with the free slot number in pooled pages. We also can estimate the living object number (== L) using last marked_slots value. We can solve this problem (how many objects should be process in gc_marks_step()) by L/C. * gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_sltos and step_slots. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@48413 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-09-11* include/ruby/ruby.h, gc.c: add new internal eventsko1
RUBY_INTERNAL_EVENT_GC_ENTER and RUBY_INTERNAL_EVENT_GC_EXIT. When invoking GC process, GC_ENTER event is called. When exiting from GC process, GC_EXIT event is called. Incremental GC (incremental marking and lazy sweep) can call these events many times. For example (minor marking): (1) GC_ENTER - (2) GC_START (minor GC) (minor marking) - (3) GC_END_MARK (start lazy sweep) (4) GC_EXIT (ruby process) (5) GC_ENTER (lazy sweep) (6) GC_EXIT (ruby process) (... repeat (5), (6)) (7) GC_ENTER (finish lazy sweep) - (8) GC_END_SWEEP (9) GC_EXIT 2nd example (incremental major marking): (1) GC_ENTER - (2) GC_START (minor GC) (start incremental marking) (3) GC_EXIT (ruby process) (4) GC_ENTER (incremental marking) (5) GC_EXIT (ruby process) (... repeat (4), (5)) (6) GC_ENTER (finish incremental marking) - (7) GC_END_MARK (start lazy sweep) (8) GC_EXIT (ruby process) (9) GC_ENTER (lazy sweep) (10) GC_EXIT (ruby process) (... repeat (9), (10)) (11) GC_ENTER (finish lazy marking) - (12) GC_STOP_SWEEP (13) GC_EXIT Thease internal events enable to measure GC pause time completely. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47528 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
