* gc.c (obj_id_to_ref): add a macro to treat Bignum object id.

2012-12-22T04:25:18+00:00

  This follows the change r38493.

* gc.c (id2ref): fix for working fine with Bignum object id on x64
  Windows.
* gc.c (wmap_finalize): ditto.

* gc.c (nonspecial_obj_id): VALUE is not compatible with Fixnum on

2012-12-20T07:43:54+00:00

  LLP64 platform, such as 64bit Windows.
  reporeted by Heesob Park at [ruby-core:50255] [Bug #7454], and the
  fix is suggested by akr.

* signal.c (rb_sigaltstack_size): new. calculate stack size for

2012-12-15T14:20:12+00:00

  sigsegv handler. enlarge value when x86 or x86_64 on Linux.
  Linux has very small MINSIGSTKSZ size (2048 bytes) and
  our sigsegv routine need 5KiB at least. [Bug #7141]
* internal.h: add declaration of rb_sigaltstack_size().
* vm_core.h: remove ALT_STACK_SIZE definition.

* signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with
  rb_sigaltstack_size();
* gc.c (Init_heap): ditto.
* vm.c (th_init): ditto.

* revised r37993 to avoid SEGV/ILL in tests. In r37993, a method

2012-12-06T13:08:41+00:00

  entry with VM_METHOD_TYPE_REFINED holds only the original method
  definition, so ci->me is set to a method entry allocated in the
  stack, and it causes SEGV/ILL.  In this commit, a method entry
  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
  avoid GC for iclasses created by copy_refinement_iclass().

* vm_method.c (rb_method_entry_make): add a method entry with
  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
  the target module is a refinement.  When a method entry with
  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
  the same name is searched in refinements.  If such a method is
  found, the method is invoked.  Otherwise, the original method in
  the refined class (rb_method_definition_t::body.orig_me) is
  invoked.  This change is made to simplify the normal method lookup
  and to improve the performance of normal method calls.

* vm_method.c (EXPR1, search_method, rb_method_entry),
  vm_eval.c (rb_call0, rb_search_method_entry): do not use
  refinements for method lookup.

* vm_insnhelper.c (vm_call_method): search methods in refinements if
  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
  super (i.e., ci->call == vm_call_super_method), skip the same
  method entry as the current method to avoid infinite call of the
  same method.

* class.c (include_modules_at): add a refined method entry for each
  method defined in a module included in a refinement.

* class.c (rb_prepend_module): set an empty table to
  RCLASS_M_TBL(klass) to add refined method entries, because
  refinements should have priority over prepended modules.

* proc.c (mnew): use rb_method_entry_with_refinements() to get
  a refined method.

* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
  copy_refinement_iclass().

* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.

* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
  the test because it should pass successfully.

* test/ruby/test_refinement.rb (test_redefine_refined_method): new
  test for the case a refined method is redefined.

* gc.c (getrusage_time): uses clock_gettime() with

2012-12-05T14:53:16+00:00

  CLOCK_PROCESS_CPUTIME_ID when available, which provides a 1ns
  precision on linux. [ruby-core:50495] [Bug #7500]

2012-12-01T09:30:24+00:00

  suppress unused-value warnings, even with valgrind enabled.
