introduce rb_autoload_str to replace rb_autoload
rb_autoload_str may be safer by preventing premature GC. It can also be more efficient by passing a pre-frozen string that can be deduped using rb_fstring. Common autoload callers (e.g. rubygems, rdoc) already use string literals as the file argument. There seems to be no reason to expose rb_autoload_str to the public C API since autoload is not performance-critical. Applications may declare autoloads in Ruby code or via rb_funcall; so merely deprecate rb_autoload without exposing rb_autoload_str to new users. Running: valgrind -v ruby -rrdoc -rubygems -e exit shows a minor memory reduction (32-bit userspace) before: in use at exit: 1,600,621 bytes in 28,819 blocks total heap usage: 55,786 allocs, 26,967 frees, 6,693,790 bytes allocated after: in use at exit: 1,599,778 bytes in 28,789 blocks total heap usage: 55,739 allocs, 26,950 frees, 6,692,973 bytes allocated * include/ruby/intern.h (rb_autoload): deprecate * internal.h (rb_autoload_str): declare * load.c (rb_mod_autoload): use rb_autoload_str * variable.c (rb_autoload): become compatibility wrapper (rb_autoload_str): hoisted out from old rb_autoload [ruby-core:71369] [Feature #11664] git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
