* parse.y: change Symbol <-> ID relationship to avoid
exposing IDs from collectable symbols. [Bug #10014] Now, rb_check_id() returns 0 if corresponding symbol is pinned dynamic symbol. There is remaining intern_cstr_without_pindown(), it can return IDs from collectable symbols. We must be careful to use it (only used in parse.y). I think it should be removed if it does not have impact for performance. * parse.y: add: * STATIC_SYM2ID() * STATIC_ID2SYM() rename: * rb_pin_dynamic_symbol() -> dsymbol_pindown() * internal.h: remove: * rb_check_id_without_pindown() * rb_sym2id_without_pindown() add: * rb_check_symbol() * rb_check_symbol_cstr() * load.c: use rb_check_id() or rb_check_id_cstr(). * object.c: ditto. * struct.c: ditto. * thread.c: ditto. * vm_method.c: ditto. * string.c (sym_find): use only rb_check_symbol(). * sprintf.c (rb_str_format): use rb_check_symbol_cstr(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46764 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
