* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):

2010-05-05T17:51:21+00:00

  added.  Unlinked method entries are collected to
  vm->unlinked_method_entry_list.  On the GC timing, mark all method
  entries which are on all living threads.  Only non-marked method
  entries are collected.  This hack prevents releasing living method
  entry.
  [Performance Consideration] Since this Method Entry GC (MEGC)
  doesn't occuer frequently, MEGC will not be a performance bottleneck.
  However, to traverse living method entries, every control frame push
  needs to clear cfp->me field.  This will be a performance issue
  (because pushing control frame is occurred frequently).
  Bug #2777 [ruby-dev:40457]
* cont.c (fiber_init): init cfp->me.
* gc.c (garbage_collect): kick rb_sweep_method_entry().
* method.h (rb_method_entry_t): add a mark field.
* vm.c (invoke_block_from_c): set passed me.
* vm.c (rb_thread_mark): mark cfp->me.
* vm_core.h (rb_thread_t): add a field passed_me.
* vm_core.h (rb_vm_t): add a field unlinked_method_entry_list.
* vm_insnhelper.c (vm_push_frame): clear cfp->me at all times.
* vm_insnhelper.c (vm_call_bmethod): pass me.
* bootstraptest/test_method.rb: add a test.

* vm_method.c (rb_add_method_def): workarond fix for redefinition

2010-04-18T17:59:56+00:00

  of methods. This is because cfp->me uses the rb_method_entry
  which is freed by redefinition of remove_method. Note that
  reusing may cause another problem when the usage is changed.
