2016-07-28* vm.c, internal.h: remove RubyVM::Env class and all of env objectsko1
are imemo objects (imemo_env). * NEWS: describe this change. I believe nobody touch these objects because there are no method defined. * vm_core.h: remove the following definitions. * rb_cEnv decl. * GetEnvPtr() because Env is no longer T_DATA object. * vm_core.h (rb_env_t): fix layout for imemo values. * vm_core.h (vm_assert_env): added. * vm_core.h (vm_env_new): added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55768 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-07-28* vm_core.h: revisit the structure of frame, block and env.ko1
[Bug #12628] This patch introduce many changes. * Introduce concept of "Block Handler (BH)" to represent passed blocks. * move rb_control_frame_t::flag to ep[0] (as a special local variable). This flags represents not only frame type, but also env flags such as escaped. * rename `rb_block_t` to `struct rb_block`. * Make Proc, Binding and RubyVM::Env objects wb-protected. Check [Bug #12628] for more details. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55766 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-07-13* gc.c (gc_mark_roots): should mark the VM object itself to markko1
singleton class of the VM object. Before this patch, we only set mark bit for the VM object and invoke mark function separately. [Bug #12583] * test/ruby/test_gc.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55663 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-05-08* configure.in: check function attirbute const and pure,naruse
and define CONSTFUNC and PUREFUNC if available. Note that I don't add those options as default because it still shows many false-positive (it seems not to consider longjmp). * vm_eval.c (stack_check): get rb_thread_t* as an argument to avoid duplicate call of GET_THREAD(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54952 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-04-21* gc.c (objspace_malloc_prepare): remove size check because it isnaruse
used by objspace_xmalloc and objspace_xcalloc. objspace_xmalloc introduces its own check in this commit. objspace_xcalloc checks with xmalloc2_size (ruby_xmalloc2_size). * gc.c (objspace_xmalloc0): common xmalloc function. * gc.c (objspace_xmalloc): introduce its own size check. * gc.c (objspace_xmalloc2): separated from ruby_xmalloc2 to clarify the layer who has the responsibility to check the size. * gc.c (objspace_xrealloc): remove duplicated size check. * gc.c (ruby_xmalloc2): use objspace_xmalloc2. * include/ruby/ruby.h (ruby_xmalloc2_size): follow the size limit as SSIZE_MAX. Note that ISO C says size_t is unsigned integer. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54661 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-04-04* gc.c: change deafult value ofko1
RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2 RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65 These values are same as Ruby 2.0.0. This change cause GC counts. However, generational GC reduced each (minor) GC time and increase memory locality. So that not so big impact on my benchmarking results. (surprizingly, this fix speed up programs on some cases) You can change these values by environment variables if you feel wrong. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54482 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-04-04* gc.c (get_envparam_double): take an upper_bound.ko1
And also take an accept_zero flag which allow to accept zero even if lower_bound is set. * gc.c (ruby_gc_set_params): fix parameters. RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO set 0.9 as *lower_bound*, so that it should be upper_bound. Set RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO as lower bound. Also set lower/upper bound of RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO to RUBY_GC_HEAP_FREE_SLOTS_MIN/MAX_RATIO. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54481 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54454 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-03-31* gc.c: change additional allocation policy.ko1
Introduce new environement variable GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the ratio of additional memory. Before this change, we add pages with the following formula (when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO): next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR This addition can allocate too much. With this change, we increase pages to satisfy the following formula: next_free_slots = next_total_slots * goal_ratio where next_free_slots = free_slots + adding_slots next_total_slots = total_slots + adding_slots. If you want to prepare many free slots, increase this ratio. If this variable is 0, then simply multiply RUBY_GC_HEAP_GROWTH_FACTOR. * gc.c (get_envparam_double): enable to accept 0. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54453 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-03-31* gc.c: simplify allocate/free detecting logic at the end of marking.ko1
Before this change, heap_pages_min_slots are calculated at the beggining sweeping phase. And this value is used at the end of *next* marking phase. To simplify it, we use this value at the end of this marking phase. It means that we don't need to store this value as global state. Also heap_pages_max_slots is calculated at the begging of sweeping phase and used at the end of sweeping phase. To simplify this logic, we introduced new global value heap_pages_freeable_pages it means extra pages count we can free. gc_sweep_step() checks this value and moves empty pages to tomb_heap not more than this value. Because of this fix, heap_pages_swept_slots is no longer needed. * gc.c (rb_objspace_t::heap_pages): restruct the objspace global status. remove the following fileds * swept_slots (and heap_pages_swept_slots) * min_free_slots (and heap_pages_min_free_slots) * max_free_slots (and heap_pages_max_free_slots) And add the following filed. * freeable_pages (and heap_pages_freeable_pages) * gc.c (heap_pages_free_unused_pages): unlink tomb heap pages because tomb heap should have only freeable pages. * gc.c (heap_extend_pages): add parameters for future extension. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54451 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-03-31* gc.c: add GC parameters to configure the following values:ko1
* RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO: allocate additional pages when free slots is lower than the value (total_slots * (this ratio)). * RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO: allow to free pages when free slots is greater thatn the value (total_slots * (this ratio)). Before this change, these values are hard coded. * gc.c (ruby_gc_params_t): ditto. * gc.c (ruby_gc_set_params): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54450 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
