2013-06-05 * gc.c (gc_mark): get rid of pushing useless objests.tarui
* gc.c (rgengc_rememberset_mark): bypass gc_mark() in order to push sunny old object at minor gc. * gc.c (gc_mark_children): move sunny old check to gc_mark(). * gc.c (rgengc_check_shady): remove DEMOTE that already unnecessary. * gc.c (rb_gc_writebarrier): ditto. change sunny old check point in order to save mark stack and remove unnatural rest_sweep & demote. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41097 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-05-27* include/ruby/ruby.h, gc.c: add new internal eventko1
RUBY_INTERNAL_EVENT_GC_END. This event invokes at the end of after_sweep(). Time chart with lazy sweep is here: (1) Kick RUBY_INTERNAL_EVENT_GC_START (2) [gc_marks()] (3) [lazy_sweep()] (4) [... run Ruby program (mutator) with lazy_sweep() ...] (5) [after_sweep()] (6) Kick RUBY_INTERNAL_EVENT_GC_END (7) [... run Ruby program (mutator), and go to (1) ...] * ext/-test-/tracepoint/tracepoint.c, test/-ext-/tracepoint/test_tracepoint.rb: modify a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40963 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-05-27* include/ruby/ruby.h: rename RUBY_INTERNAL_EVENT_FREE toko1
RUBY_INTERNAL_EVENT_FREEOBJ. * ext/-test-/tracepoint/tracepoint.c, ext/objspace/object_tracing.c, gc.c, vm_trace.c: catch up this change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40959 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-05-27* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.ko1
Read the following test to know HOWTO. This feature is a sample of RUBY_INTERNAL_EVENT. * test/objspace/test_objspace.rb: add a test. * ext/objspace/object_tracing.c: ditto. * gc.c (rb_gc_count): add. THis function returns GC count. * internal.h: add decl. of rb_gc_count(). Same as `GC.count'. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40957 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-05-27* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.ko1
* RUBY_INTERNAL_EVENT_NEWOBJ: object created. * RUBY_INTERNAL_EVENT_FREE: object freeed. * RUBY_INTERNAL_EVENT_GC_START: GC started. And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'. Internal events can not invoke any Ruby program because the tracing timing may be critical (under huge restriction). These events can be hooked only by C-extensions. We recommend to use rb_potponed_job_register() API to call Ruby program safely. This change is mostly written by Aman Gupta (tmm1). https://bugs.ruby-lang.org/issues/8107#note-12 [Feature #8107] * include/ruby/debug.h, vm_trace.c: added two new APIs. * rb_tracearg_event_flag() returns rb_event_flag_t of this event. * rb_tracearg_object() returns created/freeed object. * ext/-test-/tracepoint/extconf.rb, ext/-test-/tracepoint/tracepoint.c, test/-ext-/tracepoint/test_tracepoint.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40946 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-05-26* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.ko1
Postponed jobs are registered with this API. Registered jobs are invoked at `ruby-running-safe-point' as soon as possible. This timing is completely same as finalizer timing. There are two APIs: * rb_postponed_job_register(flags, func, data): register a postponed job with data. flags are reserved. * rb_postponed_job_register_one(flags, func, data): same as `rb_postponed_job_register', but only one `func' job is registered (skip if `func' is already registered). This change is mostly written by Aman Gupta (tmm1). https://bugs.ruby-lang.org/issues/8107#note-15 [Feature #8107] * gc.c: use postponed job API for finalizer. * common.mk: add dependency from vm_trace.c to debug.h. * ext/-test-/postponed_job/extconf.rb, postponed_job.c, test/-ext-/postponed_job/test_postponed_job.rb: add a test. * thread.c: implement postponed API. * vm_core.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40940 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-05-21* gc.c (garbage_collect): all GC is start from garbage_collect()ko1
(or garbage_collect_body()). `garbage_collect()' accept additional two parameters `full_mark' and `immediate_sweep'. If `full_mark' is TRUE, then force it full gc (major gc), otherwise, it depends on status of object space. Now, it will be minor gc. If `immediate_sweep' is TRUE, then disable lazy sweep. To allocate free memory, `full_mark' and `immediate_sweep' should be TRUE. Otherwise, they should be FALSE. * gc.c (gc_prepare_free_objects): use `garbage_collect_body()'. * gc.c (slot_sweep, before_gc_sweep, after_gc_sweep): add logging code. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40884 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-05-13* gc.c: support RGENGC. [ruby-trunk - Feature #8339]ko1
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
