* proc.c (rb_binding_new_with_cfp): permit to create binding object

2013-02-05T06:04:59+00:00

  of IFUNC frame.
  When `rb_binding_new_with_cfp()' is called, VM finds out the first
  normal (has iseq) frame and create a binding object of this frame
  and create Env objects. `ep's of related frames are updated
  (`ep's point Env object managed spaces).
  However, `ep' of skipped IFUNC frame was not updated and
  old invalid `ep' was remained. It causes serious problems.
  To solve this issue, permit IFUNC to create binding.
  (Maybe there is no problem on it)
  [ruby-dev:46908] [ruby-trunk - Bug #7774]
* test/ruby/test_settracefunc.rb: add a test.
* vm.c (rb_vm_get_binding_creatable_next_cfp), vm_core.h: added.
* vm_trace.c: fix to use `rb_vm_get_binding_creatable_next_cfp()'.

* vm_backtrace.c: fix issue of rb_debug_inspector_open().

2013-01-29T08:25:32+00:00

  The order of making binding should be stack (frame) top to bottom.
  [Bug #7635]
  And also fix issue of collecting klass. Collecting klass is same
  as TracePoint#defined_class.
  (previous version, it returns T_ICLASS (internal objects).
* test/-ext-/debug/test_debug.rb: add a test.
* ext/-test-/debug/extconf.rb, init.c, inspector.c: ditto.
* vm_backtrace.c: remove magic number and add enum CALLER_BINDING_*.
* vm_backtrace.c, include/ruby/debug.h: add new C api (experimental)
  rb_debug_inspector_frame_self_get().
* vm.c, vm_core.h, vm_trace.c: move decl. of
  rb_vm_control_frame_id_and_class() and constify first parameter.

* vm_core.h (VM_DEBUG_BP_CHECK): set 0 as default.

2013-01-10T13:03:39+00:00

  This flag specifies checking BP consistency on each frame popping.
  Now, we don't have any trouble on it, so I remove it.
  If you feel any bugs about VM execution, then set it to 1.

vm_core.h: flip_cnt in rb_iseq_t

2013-01-08T05:41:44+00:00

* vm_core.h (rb_iseq_t): move flip_cnt from struct iseq_compile_data,

* vm_core.h (EXEC_EVENT_HOOK_AND_POP_FRAME): add to use
  `rb_threadptr_exec_event_hooks_and_pop_frame()'.
