2013-10-29* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only useko1
safe functions during garbage collection such as xfree(). On default, T_DATA objects are freed at same points as fianlizers. This approach protects issues such as reported by [ruby-dev:35578]. However, freeing T_DATA objects immediately helps heap usage. Most of T_DATA (in other words, most of dfree functions) are safe. However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default for safety. * cont.c: ditto. * dir.c: ditto. * encoding.c: ditto. * enumerator.c: ditto. * error.c: ditto. * file.c: ditto. * gc.c: ditto. * io.c: ditto. * iseq.c: ditto. * marshal.c: ditto. * parse.y: ditto. * proc.c: ditto. * process.c: ditto. * random.c: ditto. * thread.c: ditto. * time.c: ditto. * transcode.c: ditto. * variable.c: ditto. * vm.c: ditto. * vm_backtrace.c: ditto. * vm_trace.c: ditto. * ext/bigdecimal/bigdecimal.c: ditto. * ext/objspace/objspace.c: ditto. * ext/stringio/stringio.c: ditto. * ext/strscan/strscan.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43466 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

See this ticet about RGENGC. * gc.c: Add several flags: * RGENGC_DEBUG: if >0, then prints debug information. * RGENGC_CHECK_MODE: if >0, add assertions. * RGENGC_PROFILE: if >0, add profiling features. check GC.stat and GC::Profiler. * include/ruby/ruby.h: disable RGENGC by default (USE_RGENGC == 0). * array.c: add write barriers for T_ARRAY and generate sunny objects. * include/ruby/ruby.h (RARRAY_PTR_USE): added. Use this macro if you want to access raw pointers. If you modify the contents which pointer pointed, then you need to care write barrier. * bignum.c, marshal.c, random.c: generate T_BIGNUM sunny objects. * complex.c, include/ruby/ruby.h: add write barriers for T_COMPLEX and generate sunny objects. * rational.c (nurat_s_new_internal), include/ruby/ruby.h: add write barriers for T_RATIONAL and generate sunny objects. * internal.h: add write barriers for RBasic::klass. * numeric.c (rb_float_new_in_heap): generate sunny T_FLOAT objects. * object.c (rb_class_allocate_instance), range.c: generate sunny T_OBJECT objects. * string.c: add write barriers for T_STRING and generate sunny objects. * variable.c: add write barriers for ivars. * vm_insnhelper.c (vm_setivar): ditto. * include/ruby/ruby.h, debug.c: use two flags FL_WB_PROTECTED and FL_OLDGEN. * node.h (NODE_FL_CREF_PUSHED_BY_EVAL, NODE_FL_CREF_OMOD_SHARED): move flag bits. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40703 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-05-13* include/ruby/ruby.h: constify RBasic::klass and addko1
RBASIC_CLASS(obj) macro which returns a class of `obj'. This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. * object.c: add new function rb_obj_reveal(). This function reveal interal (hidden) object by rb_obj_hide(). Note that do not change class before and after hiding. Only permitted example is: klass = RBASIC_CLASS(obj); rb_obj_hide(obj); .... rb_obj_reveal(obj, klass); TODO: API design. rb_obj_reveal() should be replaced with others. TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable? (We have similar experience at Ruby 1.9, for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". * internal.h: add some macros. * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal object. * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS without write barrier (planned). * RCLASS_SET_SUPER(a, b) set super class of a. * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: Use above macros and functions to access RBasic::klass. * ext/coverage/coverage.c, ext/readline/readline.c, ext/socket/ancdata.c, ext/socket/init.c, * ext/zlib/zlib.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40691 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
