2014-09-14compile.c, gc.c: suppress warningsnobu
* compile.c (iseq_compile_each): suppress implicit conversion warning by old apple gcc 4.2. * gc.c (RVALUE_FLAGS_AGE, heap_page_allocate): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47580 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-09-11* vm.c (rb_vm_register_special_exception): make new function toko1
make and register special exceptions. * vm.c (rb_vm_mark): do not need to mark special exceptions because they are registerd by rb_gc_register_mark_object(). * eval.c (Init_eval): use rb_vm_register_special_exception(). * gc.c (Init_GC): ditto. * proc.c (Init_Proc): ditto. * thread.c (Init_Thread): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47534 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-09-11* gc.c (rb_gc_mark_values): added.ko1
This function is similar to rb_gc_mark_locations(), but not conservertive. * internal.h: ditto. * vm.c (env_mark): use rb_gc_mark_values() because env values should be Ruby VALUEs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47533 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

2014-09-08* gc.c: add incremental GC algorithm. [Feature #10137]ko1
Please refer this ticket for details. This change also introduces the following changes. * Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3). Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in RBasic::flags (2 bit). Age == 3 objects become old objects. * WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap. * LONG_LIVED bitmap to represent living objects while minor GCs It specifies (1) Old objects and (2) remembered shady objects. * Introduce rb_objspace_t::marked_objects which counts marked objects in current marking phase. marking count is needed to introduce incremental marking. * rename mark related function and sweep related function to gc_(marks|sweep)_(start|finish|step|rest|continue). * rename rgengc_report() to gc_report(). * Add obj_info() function to get cstr of object details. * Add MEASURE_LINE() macro to measure execution time of specific line. * and many small fixes. * include/ruby/ruby.h: add flag USE_RINCGC. Now USE_RINCGC can be set only with USE_RGENGC. * include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1 to count object age. * include/ruby/ruby.h: rewrite write barriers for incremental marking. * debug.c: catch up flag name changes. * internal.h: add rb_gc_writebarrier_remember() instead of rb_gc_writebarrier_remember_promoted(). * array.c (ary_memcpy0): use rb_gc_writebarrier_remember(). * array.c (rb_ary_modify): ditto. * hash.c (rb_hash_keys): ditto. * hash.c (rb_hash_values): ditto. * object.c (init_copy): use rb_copy_wb_protected_attribute() because FL_WB_PROTECTED is moved from RBasic::flags. * test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47444 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-07-09* symbol.c: remove rb_gc_mark_symbols().ko1
fstrings refered by static symbols and pinned dynamic symbols are registerd by rb_gc_register_mark_object(). frstring refered by dynamic symbols (not pinned symbols) are refered from global_symbols.dsymbol_fstr_hash (Hash object). Note that fstrings refered from dynamic symbols must live loger than symbol objects themselves because rb_gc_free_dsymbol() uses fstring to remove from symbol tables. This is why we can not mark fstrings from dynamic symbols. This technique reduces root objects for GC marking. * gc.c (gc_mark_roots): ditto. * internal.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46772 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
