2012-12-22* gc.c (obj_id_to_ref): add a macro to treat Bignum object id.shirosaki

2012-12-20* gc.c (nonspecial_obj_id): VALUE is not compatible with Fixnum onusa
LLP64 platform, such as 64bit Windows. reporeted by Heesob Park at [ruby-core:50255] [Bug #7454], and the fix is suggested by akr. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38493 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38409 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-12-06* revised r37993 to avoid SEGV/ILL in tests. In r37993, a methodshugo
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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38236 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
