2013-07-24* array.c, gc.c: move ary_unprotect_logging() intoko1
rb_gc_unprotect_logging() which is general version * include/ruby/ruby.h: add USE_RGENGC_LOGGING_WB_UNPROTECT to enable. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42151 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-23* gc.c (gc_before_sweep): fix spacing.ko1
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42132 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-23* gc.c (heap_get_freeobj): clear slot->freelist here.ko1
This means that this slot doesn't have any free objects. And store this slot with objspace->heap.using_slot. * gc.c (gc_before_sweep): restore objspace->freelist into objspace->heap.using_slot->freelist. This means that using_slot has free objects which are pointed from objspace->freelist. * gc.c (gc_slot_sweep): do not need to clear slot->freelist. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42131 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-07-19* gc.c, internal.h (rb_gc_writebarrier_remember_promoted): add a newko1
function to remember an specified object. This api is only experimental (strongly depend on WB/rgengc strategy). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42062 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c: rename gc related functions with prefix "gc_".ko1
* before_gc_sweep() -> gc_before_sweep(). * after_gc_sweep() -> gc_after_sweep(). * lazy_sweep() -> gc_lazy_sweep(). * rest_sweep() -> gc_rest_sweep(). * slot_sweep() -> gc_slot_sweep(). * gc.c: rename a heap management function with prefix "heap_". * get_freeobj() -> heap_get_freeobj(). * gc.c: rename markable_object_p() to is_markable_object(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42030 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c: rename heap management functions with prefix "heap_".ko1
* allocate_sorted_array() -> heap_allocate_sorted_array(). * slot_add_freeobj() -> heap_slot_add_freeobj(). * assign_heap_slot() -> heap_assign_slot(). * add_heap_slots() -> heap_add_slots(). * init_heap() -> heap_init(). * set_heap_increment() -> heap_set_increment(). * gc.c (initial_expand_heap): inlined in rb_gc_set_params(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42026 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c: catch up last changes for debugging/checking mode.ko1
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42024 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c (rb_objspace_free): free slot itself.ko1
* gc.c (objspace_each_objects): fix condition. Use slot->body instead of slot. * gc.c (count_objects): use "slot" variable. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c (unlink_heap_slot): fix memory leak.ko1
free slot itself at free_heap_slot(). Reproduce-able code is here: N1 = 100_000; N2 = 1_000_000 N1.times{ary = []; N2.times{ary << ''}} Maybe this problem is remaining in Ruby 2.0.0. * gc.c (unlink_heap_slot): remove not working code. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42022 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c: re-design the heap structure.ko1
(1) The heap is consists of a set of slots. (2) Each "slot" has a "slot_body". slot::start and slot::limit specify RVALUE beginning address and number of RVALUE in a "slot_body". (3) "slot_body" contains a pointer to slot (slot_body::header::slot) and an array of RVALUE. (4) heap::sorted is an array of "slots", sorted by an address of slot::body. See https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/GC_design for more details (figure). * gc.c: Avoid "heaps" terminology. It is ambiguous. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42021 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-17* gc.c: fix heaps_header and heaps_slot to reduce memory consumption.ko1
(1) move heaps_header::start and limit to heaps_slot. (2) remove heaps_header::end which can be calculated by start+limit. * gc.c: catch up above change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42020 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-16* gc.c: slim a path of newobj_of().ko1
* gc.c (objspace): add a new field objspace::freelist, which contains available RVALUEs. * gc.c (newobj_of): simply call new function `get_freeobj()'. get_freeobj() returns objspace::freelist. If objspace::freelist is not available, refill objspace::freelist with a slot pointed by objspace::heap::free_slots. * gc.c (before_gc_sweep): clear objspace::freelist. * gc.c (slot_sweep): clear slot::freelist. * gc.c (heaps_prepare_freeslot): renamed to heaps_prepare_freeslot. * gc.c (unlink_free_heap_slot): remove unused function. * gc.c (rb_free_const_table): remove unused function. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42005 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-16* gc.c (link_free_heap_slot): removed.ko1
