* Return same ISeq object for one src.ko12018-12-061-35/+51
| | | | | | | | | | | | | | | | | | | | | * iseq.c: before this patch, RubyVM::InstructionSequence.of(src) (ISeq in short) returns different ISeq (wrapper) objects point to one ISeq internal object. This patch changes this behavior to cache created ISeq (wrapper) objects and return same ISeq object for an internal ISeq object. * iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects. * iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid ISEQ_USE_COMPILE_DATA but compiled_data == NULL case. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and `rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to `rb_iseq_t::aux::exec::local_hooks`. * test/ruby/test_iseq.rb: add ISeq.of() tests. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66246 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Support targetting TracePoint [Feature #15289]ko12018-11-261-63/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

* ext/coverage/: add the oneshot modemame2018-10-201-1/+23
| | | | | | | | | | | | This patch introduces "oneshot_lines" mode for `Coverage.start`, which checks "whether each line was executed at least once or not", instead of "how many times each line was executed". A hook for each line is fired at most once, and after it is fired, the hook flag was removed; it runs with zero overhead. See [Feature #15022] in detail. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* iseq.c: add a map from encoded insn to insn datamame2018-08-231-0/+52
| | | | | | | | | | This enhances rb_vm_insn_addr2insn which retrieves a decoded insn number from encoded insn. The insn data table include not only decoded insn number, but also its len, trace and non-trace version of encoded insn. This table can be used to simplify trace instrumentation. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64518 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* check trace flags at loading [Bug #14702]ko12018-08-231-4/+10
| | | | | | | | | | | | * iseq.c (iseq_init_trace): at ISeq loading time, we need to check `ruby_vm_event_enabled_flags` to turn on trace instructions. Seprate this checking code from `finish_iseq_build()` and make new function. `iseq_ibf_load()` calls this funcation after loading. * test/ruby/test_iseq.rb: add a test for this fix. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64514 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: remove coverage-related code fragmentsmame2018-08-221-0/+8
| | | | | | | | | | | | | The code fragments that initializes coverage data were scattered into both parse.y and compile.c. parse.y allocated a coverage data, and compile.c initialize the data. To remove this cross-cutting concern, this change moves the allocation from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c. For the sake, parse.y just counts the line number of the original source code, and the number is passed via rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64508 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* thread.c (rb_reset_coverages): remove coverage counters from all ISeqsmame2018-08-221-0/+19
| | | | | | | | | | | | | When coverage measurement is enabled, the compiler makes each iseq have a reference to the counter array of coverage. Even after coverage measurement is disabled, the reference is kept. And, if coverage measurement is restarted, a coverage hook will increase the counter. This is completely meaningless; it brings just overhead. To remove this meaninglessness, this change removes all the reference when coverage measuement is stopped. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64504 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* insns.def (invokesuper): remove a dummy receiever flag hack for ZSUPERmame2018-08-101-0/+1
| | | | | | | | | | | | | | | This is just a refactoring. The receiver of "invokesuper" was a boolean to represent if it is ZSUPER or not. This was used in vm_search_super_method to prohibit ZSUPER call in define_method. (It is currently prohibited because of the limitation of the implementation.) This change removes the hack by introducing an explicit flag, VM_CALL_SUPER, to signal the information. Now, the implementation of "invokesuper" is consistent with "send" instruction. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64268 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: disable calling JIT-ed codek0kubun2018-06-231-0/+2
| | | | | | | | | | | when TracePoint is enabled. We're cancelling JIT-ed code execution AFTER each instruction, but there is no guard before the first insn of method. To prevent spoiling performance, I don't want to modify the JIT-ed code to fix this. So this commit replaces `mjit_enabled` check with `mjit_call_p` check. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63734 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
