2019-08-01Make attr* methods define public methods if self in caller is not same as ↵Jeremy Evans
receiver Previously, attr* methods could be private even if not in the private section of a class/module block. This uses the same approach that ruby started using for define_method in 1fc33199736f316dd71d0c551edbf514528ddde6. Fixes [Bug #4537]

2019-04-05add definemethod/definesmethod insn.ko1
* insns.def: add definemethod and definesmethod (singleton method) instructions. Old YARV contains these instructions, but it is moved to methods of FrozenCore class because remove number of instructions can improve performance for some techniques (static stack caching and so on). However, we don't employ these technique and it is hard to optimize/analysis definition sequence. So I decide to introduce them (and remove definition methods). `putiseq` insn is also removed. * vm_method.c (rb_scope_visibility_get): renamed to `vm_scope_visibility_get()` and make it accept `ec`. Same for `vm_scope_module_func_check()`. These fixes are result of refactoring `vm_define_method`. * vm_insnhelper.c (rb_vm_get_cref): renamed to `vm_get_cref` because of consistency with other functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67442 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-11-26Support targetting TracePoint [Feature #15289]ko1
* vm_trace.c (rb_tracepoint_enable_for_target): support targetting TracePoint. [Feature #15289] Tragetting TracePoint is only enabled on specified method, proc and so on, example: `tp.enable(target: code)`. `code` should be consisted of InstructionSeuqnece (iseq) (RubyVM::InstructionSeuqnece.of(code) should not return nil) If code is a tree of iseq, TracePoint is enabled on all of iseqs in a tree. Enabled tragetting TracePoints can not enabled again with and without target. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks` to store local hooks. `rb_iseq_t::aux::trace_events` is renamed to `global_trace_events` to contrast with `local_hooks`. * vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running` to represent how many Threads/Fibers are used this list. If this field is 0, nobody using this hooks and we can delete it. This is why we can remove code from cont.c. * vm_core.h (rb_vm_t): because of above change, we can eliminate `rb_vm_t::trace_running` field. Also renamed from `rb_vm_t::event_hooks` to `global_hooks`. * vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed from `ruby_vm_event_enabled_flags. * vm_core.h, vm.c (ruby_vm_event_local_num): added to count enabled targetting TracePoints. * vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts hook list. * vm_core.h (rb_vm_global_hooks): added for convinience. * method.h (rb_method_bmethod_t): added to maintain Proc and `rb_hook_list_t` for bmethod (defined by define_method). * prelude.rb (TracePoint#enable): extracet a keyword parameter (because it is easy than writing in C). It calls `TracePoint#__enable` internal method written in C. * vm_insnhelper.c (vm_trace): check also iseq->local_hooks. * vm.c (invoke_bmethod): check def->body.bmethod.hooks. * vm.c (hook_before_rewind): check iseq->local_hooks and def->body.bmethod.hooks before rewind by exception. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66003 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-08-13Support optional inherit argument for Module#method_defined?usa
Module has many introspection methods for methods and constants that either return an array or return true or false for whether the method or constant is defined. Most of these methods support an optional argument that controls whether to consider inheritance. Currently, the following Module methods support such a argument: * const_defined? * constants * instance_methods * private_instance_methods * protected_instance_methods * public_instance_methods and the following methods do not: * method_defined? * private_method_defined? * protected_method_defined? * public_method_defined? This patch supports such an argument for the *method_defined? methods. While you can currently work around the lack of support via: mod.instance_methods(false).include?(:method_name) This patch allows the simpler and more efficient: mod.method_defined?(:method_name, false) One case where you want to exclude inheritance when checking for a method definition is when you want to replace a method that may already exist. To avoid a verbose warning, you want to remove the method only if it is already defined: remove_method(:foo) if method_defined?(:foo, false) define_method(:foo){} You can't call remove_method without checking for the method definition, as that can raise a NameError, and you don't want to include inheritance because remove_method will still raise a NameError if the method is defined by an ancestor and not by the module itself.

2018-02-04mjit_compile.c: merge initial JIT compilerk0kubun
which has been developed by Takashi Kokubun <takashikkbn@gmail> as YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>. This JIT compiler is designed to be a safe migration path to introduce JIT compiler to MRI. So this commit does not include any bytecode changes or dynamic instruction modifications, which are done in original MJIT. This commit even strips off some aggressive optimizations from YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still fairly faster than Ruby 2.5 in some benchmarks (attached below). Note that this JIT compiler passes `make test`, `make test-all`, `make test-spec` without JIT, and even with JIT. Not only it's perfectly safe with JIT disabled because it does not replace VM instructions unlike MJIT, but also with JIT enabled it stably runs Ruby applications including Rails applications. I'm expecting this version as just "initial" JIT compiler. I have many optimization ideas which are skipped for initial merging, and you may easily replace this JIT compiler with a faster one by just replacing mjit_compile.c. `mjit_compile` interface is designed for the purpose. common.mk: update dependencies for mjit_compile.c. internal.h: declare `rb_vm_insn_addr2insn` for MJIT. vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to compiler. This avoids to include some functions which take a long time to compile, e.g. vm_exec_core. Some of the purpose is achieved in transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are manually resolved for now. Load mjit_helper.h for MJIT header. mjit_helper.h: New. This is a file used only by JIT-ed code. I'll refactor `mjit_call_cfunc` later. vm_eval.c: add some #ifdef switches to skip compiling some functions like Init_vm_eval. win32/mkexports.rb: export thread/ec functions, which are used by MJIT. include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify that a function is exported only for MJIT. array.c: export a function used by MJIT. bignum.c: ditto. class.c: ditto. compile.c: ditto. error.c: ditto. gc.c: ditto. hash.c: ditto. iseq.c: ditto. numeric.c: ditto. object.c: ditto. proc.c: ditto. re.c: ditto. st.c: ditto. string.c: ditto. thread.c: ditto. variable.c: ditto. vm_backtrace.c: ditto. vm_insnhelper.c: ditto. vm_method.c: ditto. I would like to improve maintainability of function exports, but I believe this way is acceptable as initial merging if we clarify the new exports are for MJIT (so that we can use them as TODO list to fix) and add unit tests to detect unresolved symbols. I'll add unit tests of JIT compilations in succeeding commits.
