* hash: keep fstrings of tainted strings for string keysnormal2017-07-181-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The same hash keys may be loaded from tainted data sources frequently (e.g. parsing headers from socket or loading YAML data from a file). If a non-tainted fstring already exists (because the application expects the hash key), cache and deduplicate the tainted version in the new tainted_frozen_strings table. For non-embedded strings, this also allows sharing with the underlying malloc-ed data. * vm_core.h (rb_vm_struct): add tainted_frozen_strings * vm.c (ruby_vm_destruct): free tainted_frozen_strings (Init_vm_objects): initialize tainted_frozen_strings (rb_vm_tfstring_table): accessor for tainted_frozen_strings * internal.h: declare rb_fstring_existing, rb_vm_tfstring_table * hash.c (fstring_existing_str): remove (moved to string.c) (hash_aset_str): use rb_fstring_existing * string.c (rb_fstring_existing): new, based on fstring_existing_str (tainted_fstr_update): new (rb_fstring_existing0): new, based on fstring_existing_str (rb_tainted_fstring_existing): new, special case for tainted strings (rb_str_free): delete from tainted_frozen_strings table * test/ruby/test_optimization.rb (test_hash_reuse_fstring): new test [ruby-core:82012] [Bug #13737] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59354 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* compile.c: optimize literal String range in case/when dispatchnormal2017-04-011-0/+15
| | | | | | | | | | | | | | | | | | | This is similar in spirit to opt_case_dispatch as the literal Range here is guaranteed to be immutable when used for checkmatch. Normal range literals with non-frozen strings are actually mutable, as Range#begin and Range#end exposes the strings to modification. So those Range objects cannot be frozen without breaking compatibility, but Ranges in case/when dispatch can be frozen at compile time. * compile.c (iseq_peephole_optimize): persistent Range creation when String literals are used as beginning and end of range when used for case/when dispatch.
