2013-10-04gc.c: rename heap.free_num to heap.swept_numtmm1
* gc.c: rename heap.free_num as heap.swept_num to clarify meaning and avoid confusion with objspace_free_num(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43140 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-10-04gc.c: add objspace_free_num and make GC.stat[:heap_free_num] use ittmm1
* gc.c (objspace_free_num): new method for available/free slots on heap. [ruby-core:57633] [Bug #8983] * gc.c (gc_stat): change heap_free_num definition to use new method. * test/ruby/test_gc.rb: test for above. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43139 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

CALC_EXACT_MALLOC_SIZE is true. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43130 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-10-02* gc.c: relax GC condition due to malloc_limit.ko1

RUBY_GC_MALLOC_LIMIT_MAX and RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR. See r43067 for details. * gc.c (rb_gc_set_params): refactoring. And change verbose notation.

2013-09-27* gc.c: add some fine-grained profiling codes to tuning marking phase.ko1
If you enable RGENGC_PRINT_TICK to 1, then profiling results by RDTSC (on x86/amd64 environment) are printed at last. Thanks Yoshii-san. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43068 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-09-27* gc.c: simplify threshold of GC caused by malloc_increase.ko1
Now, malloc_limit is increased/decreased by mysterious logic. This fix simplify malloc_limit increase/decrease logic such as: if (malloc_increase > malloc_limit) /* so many malloc */ malloc_limit += malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1); else malloc_limit -= malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1)/4; Default value of GC_MALLOC_LIMIT_FACTOR is 1.8. malloc_limit is bounded by GC_MALLOC_LIMIT_MAX (256MB by default). This logic runs at before_sweeep(). So there are no effect from caused by lazy sweep. And we can remove malloc_increase2. * gc.c (HEAP_MIN_SLOTS, FREE_MIN, HEAP_GROWTH_FACTOR): rename to GC_HEAP_MIN_SLOTS, GC_FREE_MIN, GC_HEAP_GROWTH_FACTOR respectively. Check them by `#ifndef' so you can specify these values outside gc.c. * gc.c (ruby_gc_params_t): add initial_malloc_limit_factor and initial_malloc_limit_max. * gc.c (vm_malloc_prepare, vm_xrealloc): use vm_malloc_increase to add and check malloc_increase. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43067 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-09-25* include/ruby/ruby.h: rename RARRAY_RAWPTR() to RARRAY_CONST_PTR().ko1
RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and usecase of this macro is not acquire raw pointer, but acquire read-only pointer. So we rename to better name. RSTRUCT_RAWPTR() is also renamed to RSTRUCT_CONST_PTR() (I expect that nobody use it). * array.c, compile.c, cont.c, enumerator.c, gc.c, proc.c, random.c, string.c, struct.c, thread.c, vm_eval.c, vm_insnhelper.c: catch up this change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43043 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
