2015-07-07* vm_backtrace.c: remove debug flag introduced accidentaly.ko1
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51179 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-07-06* vm_core.h: remove rb_iseq_t::klass to reduce dynamic data.ko1
* internal.h, iseq.c (rb_iseq_klass): remove it because rb_iseq_t::klass is removed. * vm_insnhelper.c (vm_super_outside): do not see cfp->iseq, but check callable method entry on a frame. This fix simplify the logic to search super class. * test/ruby/test_method.rb: support super() from Proc. Now, [Bug #4881] and [Bug #3136] was solved. * proc.c (rb_mod_define_method): catch up this change. * vm.c (vm_define_method): ditto. * vm_backtrace.c (rb_profile_frames): now, each `frame' objects are rb_callable_method_entry_t data or iseq VALUEs. This fix introduce minor compatibility issue that rb_profile_frame_label() always returns rb_profile_frame_base_label(). * test/-ext-/debug/test_profile_frames.rb: catch up this change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51166 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-07-03* method.h: introduce rb_callable_method_entry_t to removeko1
rb_control_frame_t::klass. [Bug #11278], [Bug #11279] rb_method_entry_t data belong to modules/classes. rb_method_entry_t::owner points defined module or class. module M def foo; end end In this case, owner is M. rb_callable_method_entry_t data belong to only classes. For modules, MRI creates corresponding T_ICLASS internally. rb_callable_method_entry_t can also belong to T_ICLASS. rb_callable_method_entry_t::defined_class points T_CLASS or T_ICLASS. rb_method_entry_t data for classes (not for modules) are also rb_callable_method_entry_t data because it is completely same data. In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class. For example, there are classes C and D, and incldues M, class C; include M; end class D; include M; end then, two T_ICLASS objects for C's super class and D's super class will be created. When C.new.foo is called, then M#foo is searcheed and rb_callable_method_t data is used by VM to invoke M#foo. rb_method_entry_t data is only one for M#foo. However, rb_callable_method_entry_t data are two (and can be more). It is proportional to the number of including (and prepending) classes (the number of T_ICLASS which point to the module). Now, created rb_callable_method_entry_t are collected when the original module M was modified. We can think it is a cache. We need to select what kind of method entry data is needed. To operate definition, then you need to use rb_method_entry_t. You can access them by the following functions. * rb_method_entry(VALUE klass, ID id); * rb_method_entry_with_refinements(VALUE klass, ID id); * rb_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me); To invoke methods, then you need to use rb_callable_method_entry_t which you can get by the following APIs corresponding to the above listed functions. * rb_callable_method_entry(VALUE klass, ID id); * rb_callable_method_entry_with_refinements(VALUE klass, ID id); * rb_callable_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me); VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry() returns rb_callable_method_entry_t. You can check a super class of current method by rb_callable_method_entry_t::defined_class. * method.h: renamed from rb_method_entry_t::klass to rb_method_entry_t::owner. * internal.h: add rb_classext_struct::callable_m_tbl to cache rb_callable_method_entry_t data. We need to consider abotu this field again because it is only active for T_ICLASS. * class.c (method_entry_i): ditto. * class.c (rb_define_attr): rb_method_entry() does not takes defiend_class_ptr. * gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS. * cont.c (fiber_init): rb_control_frame_t::klass is removed. * proc.c: fix `struct METHOD' data structure because rb_callable_method_t has all information. * vm_core.h: remove several fields. * rb_control_frame_t::klass. * rb_block_t::klass. And catch up changes. * eval.c: catch up changes. * gc.c: ditto. * insns.def: ditto. * vm.c: ditto. * vm_args.c: ditto. * vm_backtrace.c: ditto. * vm_dump.c: ditto. * vm_eval.c: ditto. * vm_insnhelper.c: ditto. * vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51126 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-06-02* method.h: make rb_method_entry_t a VALUE.ko1
Motivation and new data structure are described in [Bug #11203]. This patch also solve the following issues. * [Bug #11200] Memory leak of method entries * [Bug #11046] __callee__ returns incorrect method name in orphan proc * test/ruby/test_method.rb: add a test for [Bug #11046]. * vm_core.h: remvoe rb_control_frame_t::me. me is located at value stack. * vm_core.h, gc.c, vm_method.c: remove unlinked_method... codes because method entries are simple VALUEs. * method.h: Now, all method entries has own independent method definititons. Strictly speaking, this change is not essential, but for future changes. * rb_method_entry_t::flag is move to rb_method_definition_t::flag. * rb_method_definition_t::alias_count is now rb_method_definition_t::alias_count_ptr, a pointer to the counter. * vm_core.h, vm_insnhelper.c (rb_vm_frame_method_entry) added to search the current method entry from value stack. * vm_insnhelper.c (VM_CHECK_MODE): introduced to enable/disable assertions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50728 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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].

2012-11-19* thread.c: add `Thread#backtrace_locations' method.ko1
This method is similart to `caller_locations' method for specific method. And fix to accept `level' and `n' parameters for `Thread#backtrace' and `Thread#backtrace_locations'. `caller' (and `caller_locations') do not return `caller' method frame. However, `Thread#backtrace' (and `Thread#backtrace_locations') return `Thread#backtrace' method frame itself if `Thread.current.backtrace' was called. * vm_backtrace.c: ditto. * internal.h: ditto. * test/ruby/test_backtrace.rb: add tests. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37716 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-09-08internal.h: allocator function in rb_classext_tnobu
* internal.h (struct rb_classext_struct): move allocator function into rb_classext_t from ordinary method table. [ruby-dev:46121] [Feature #6993] * object.c (rb_obj_alloc): call allocator function directly. * vm_method.c (rb_define_alloc_func, rb_undef_alloc_func) (rb_get_alloc_func): use allocator function in rb_classext_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36925 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-06-15* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).ko1
Before this commit: `finish frame' was place holder which indicates that VM loop needs to return function. If a C method calls a Ruby methods (a method written by Ruby), then VM loop will be (re-)invoked. When the Ruby method returns, then also VM loop should be escaped. `finish frame' has only one instruction `finish', which returns VM loop function. VM loop function executes `finish' instruction, then VM loop function returns itself. With such mechanism, `leave' instruction (which returns one frame from current scope) doesn't need to check that this `leave' should also return from VM loop function. Strictly, one branch can be removed from `leave' instructon. Consideration: However, pushing the `finish frame' needs costs because it needs several memory accesses. The number of pushing `finish frame' is greater than I had assumed. Of course, pushing `finish frame' consumes additional control frame. Moreover, recent processors has good branch prediction, with which we can ignore such trivial checking. After this commit: Finally, I decide to remove `finish frame' and `finish' instruction. Some parts of VM depend on `finish frame', so the new frame flag VM_FRAME_FLAG_FINISH is introduced. If this frame should escape from VM function loop, then the result of VM_FRAME_TYPE_FINISH_P(cfp) is true. `leave' instruction checks this flag every time. I measured performance on it. However on my environments, it improves some benchmarks and slows some benchmarks down. Maybe it is because of C compiler optimization parameters. I'll re-visit here if this cause problems. * insns.def (leave, finish): remove finish instruction. * vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c: apply above changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36099 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
