GC heap/page/slot sizing. * test/ruby/test_gc.rb (class TestGc): test for above. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43877 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-27* gc.c (gc_stat): add new information heap_eden_page_length andko1
heap_tomb_page_length. * test/ruby/test_gc.rb: fix to use GC.stat[:heap_eden_page_length] instead of GC.stat[:heap_length]. This test expects `heap_eden_page_length' (used pages size). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43874 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-25* internal.h: do not use ruby_sized_xrealloc() and ruby_sized_xfree()ko1
if HAVE_MALLOC_USABLE_SIZE (or _WIN32) is defined. We don't need these function if malloc_usable_size() is available. * gc.c: catch up this change. * gc.c: define HAVE_MALLOC_USABLE_SIZE on _WIN32. * array.c (ary_resize_capa): do not use ruby_sized_xfree() with local variable to avoid "unused local variable" warning. This change only has few impact. * string.c (rb_str_resize): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43839 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-24* gc.c: change terminology OLDSPACE -> OLDMALLOC.ko1
(oldspace -> oldmalloc for variable names) OLDSPACE is confusing because it is not includes slots. To more clearly, rename such as (oldspace_limit -> oldmalloc_limit). It is clear that it measures (estimates) malloc()'ed size. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43833 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-22* include/ruby/intern.h (rb_gc_set_params): Deprecatenari
rb_gc_set_params because it's only used in ruby internal. * internal.h (ruby_gc_set_params): Declare rb_gc_set_params's alias function. * gc.c: ditto. * ruby.c: use ruby_gc_set_params. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43794 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-22* vm.c (ruby_vm_destruct): do not use ruby_xfree() after freeingko1
objspace. * gc.c (ruby_mimfree): added. It is similar to ruby_mimmalloc(). * internal.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43771 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-22* gc.c: fix build failure on FreeBSD introduced by r43763.naruse
malloc_usable_size() is defined by malloc_np.h on FreeBSD. * configure.in: check malloc.h and malloc_np.h. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43769 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-21* gc.c: enable "RGENGC_ESTIMATE_OLDSPACE" option as default.ko1
Without this option, some application consumes huge memory. (and there are only a few performance down) Introduced new environment variables: * RUBY_GC_HEAP_OLDSPACE (default 16MB) * RUBY_GC_HEAP_OLDSPACE_MAX (default 128 MB) * RUBY_GC_HEAP_OLDSPACE_GROWTH_FACTOR (default 1.2) * gc.c (initial_malloc_limit): rename to initial_malloc_limit_min. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43755 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-21* gc.c (gc_marks_check): do not dump all refs.ko1

2013-11-21* gc.c: change RGENGC_CHECK_MODE (>= 2) logic.ko1
Basically, make an object graph of all of living objects before and after marking and check status. [Before marking: check WB sanity] If there is a non-old object `obj' pointed from old object (`parent') then `parent' or `obj' should be remembered. [After marking: check marking miss] Traversible objects with the object graph should be marked. (However, this alert about objects pointed by machine context can be false positive. We only display alert.) [Implementation memo] objspace_allrefs() creates an object graph. The object graph is represented by st_table, key is object (VALUE) and value is referring objects. Referring objects are stored by "struct reflist". * gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init. This pre-allocation causes failure on is_mark_stask_empty() without any pushing. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43744 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-19* gc.c (heap_is_swept_object): use heap_page::before_sweep flag.ko1

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43719 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-19* gc.c (rb_gc_resurrect): added.ko1
rb_fstring() used rb_gc_mark() to avoid freeing used string. However, rb_gc_mark() set mark bit *and* pushes mark_stack. rb_gc_resurrect() does only set mark bit if it is before sweeping. * string.c (rb_fstring): use rb_gc_resurrect. * internal.h: add decl. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43718 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-09* gc.c (vm_malloc_increase): sweep immediately on GC due to malloc().ko1
To reduce memory usage, sweep as soon as possible. This behavior is same as Ruby 2.0.0 and before. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43623 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-09gc.c: private callnobu
* gc.c (should_be_callable): allow private call since rb_eval_cmd calls even private methods. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43621 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-07gc.c: use switch for alternative BUILTIN_TYPEnobu
* gc.c (rb_objspace_call_finalizer): BUILTIN_TYPE is alternative, T_DATA object (Thread, Mutex, Fiber) cannot be T_FILE. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43576 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-07* gc.c (vm_malloc_increase): check GVL before gc_rest_sweep().ko1
vm_malloc_increase() can be called without GVL. However, gc_rest_sweep() assumes acquiring GVL. To avoid this problem, check GVL before gc_rest_sweep(). [Bug #9090] This workaround introduces possibility to set malloc_limit as wrong value (*1). However, this may be rare case. So I commit it. *1: Without rest_sweep() here, gc_rest_sweep() can decrease malloc_increase due to ruby_sized_xfree(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43574 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
