* `$SAFE` as a process global state. [Feature #14250]ko12017-12-281-29/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * vm_core.h (rb_vm_t): move `rb_execution_context_t::safe_level` to `rb_vm_t::safe_level_` because `$SAFE` is a process (VM) global state. * vm_core.h (rb_proc_t): remove `rb_proc_t::safe_level` because `Proc` objects don't need to keep `$SAFE` at the creation. Also make `is_from_method` and `is_lambda` as 1 bit fields. * cont.c (cont_restore_thread): no need to keep `$SAFE` for Continuation. * eval.c (ruby_cleanup): use `rb_set_safe_level_force()` instead of access `vm->safe_level_` directly. * eval_jump.c: End procs `END{}` doesn't keep `$SAFE`. * proc.c (proc_dup): removed and introduce `rb_proc_dup` in vm.c. * safe.c (rb_set_safe_level): don't check `$SAFE` 1 -> 0 changes. * safe.c (safe_setter): use `rb_set_safe_level()`. * thread.c (rb_thread_safe_level): `Thread#safe_level` returns `$SAFE`. It should be obsolete. * transcode.c (load_transcoder_entry): `rb_safe_level()` only returns 0 or 1 so that this check is not needed. * vm.c (vm_proc_create_from_captured): don't need to keep `$SAFE` for Proc. * vm.c (rb_proc_create): renamed to `proc_create`. * vm.c (rb_proc_dup): moved from proc.c. * vm.c (vm_invoke_proc): do not need to set and restore `$SAFE` for `Proc#call`. * vm_eval.c (rb_eval_cmd): rename a local variable to represent clearer meaning. * lib/drb/drb.rb: restore `$SAFE`. * lib/erb.rb: restore `$SAFE`, too. * test/lib/leakchecker.rb: check `$SAFE == 0` at the end of tests. * test/rubygems/test_gem.rb: do not set `$SAFE = 1`. * bootstraptest/test_proc.rb: catch up this change. * spec/ruby/optional/capi/string_spec.rb: ditto. * test/bigdecimal/test_bigdecimal.rb: ditto. * test/fiddle/test_func.rb: ditto. * test/fiddle/test_handle.rb: ditto. * test/net/imap/test_imap_response_parser.rb: ditto. * test/pathname/test_pathname.rb: ditto. * test/readline/test_readline.rb: ditto. * test/ruby/test_file.rb: ditto. * test/ruby/test_optimization.rb: ditto. * test/ruby/test_proc.rb: ditto. * test/ruby/test_require.rb: ditto. * test/ruby/test_thread.rb: ditto. * test/rubygems/test_gem_specification.rb: ditto. * test/test_tempfile.rb: ditto. * test/test_tmpdir.rb: ditto. * test/win32ole/test_win32ole.rb: ditto. * test/win32ole/test_win32ole_event.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61510 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | * safe.c (rb_set_safe_level): call `rb_vm_stack_to_heap()` to set block parameter. * safe.c (rb_set_safe_level): use `GET_EC()`. * safe.c (safe_setter): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60563 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Use rb_execution_context_t instead of rb_thread_tko12017-10-261-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | to represent execution context [Feature #14038] * vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer. There are many code using `th` to represent execution context (such as cfp, VM stack and so on). To access `ec`, they need to use `th->ec->...` (adding one indirection) so that we need to replace them by passing `ec` instead of `th`. * vm_core.h (GET_EC()): introduced to access current ec. Also remove `ruby_current_thread` global variable. * cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of rb_context_t::thread_value. * cont.c (ec_set_vm_stack): added to update vm_stack explicitly. * cont.c (ec_switch): added to switch ec explicitly. * cont.c (rb_fiber_close): added to terminate fibers explicitly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Lazy Proc allocation for block parametersko12017-10-241-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Feature #14045] * insns.def (getblockparam, setblockparam): add special access instructions for block parameters. getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and if it is not set this instruction creates a Proc object from a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. setblockparam is similar to setlocal, but set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. * compile.c: use get/setblockparm instead get/setlocal instructions. Note that they are used for method local block parameters (def m(&b)), not for block local method parameters (iter{|&b|). * proc.c (get_local_variable_ptr): creates Proc object for Binding#local_variable_get/set. * safe.c (safe_setter): we need to create Proc objects for postponed block parameters when $SAFE is changed. * vm_args.c (args_setup_block_parameter): used only for block local blcok parameters. * vm_args.c (vm_caller_setup_arg_block): if called with VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be a block handler. * test/ruby/test_optimization.rb: add tests. * benchmark/bm_vm1_blockparam*: added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60397 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
