thread_sync.c: avoid reaching across stacks of dead threads rb_ensure is insufficient cleanup for fork and we must reinitialize all waitqueues in the child process.

2017-12-20compile.c: add a RUBY_EVENT_COVERAGE_LINE event for line coveragemame
2.5's line coverage measurement was about two times slower than 2.4 because of two reasons; (1) vm_trace uses rb_iseq_event_flags (which takes O(n) currently where n is the length of iseq) to get an event type, and (2) RUBY_EVENT_LINE uses setjmp to call an event hook. This change adds a special event for line coverage, RUBY_EVENT_COVERAGE_LINE, and adds `tracecoverage` instructions where the event occurs in iseq. `tracecoverage` instruction calls an event hook without vm_trace. And, RUBY_EVENT_COVERAGE_LINE is an internal event which does not use setjmp. This change also cancells lineno change due to the deletion of trace instructions [Feature #14104]. So fixes [Bug #14191]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61350 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-05Revamp method coverage to support define_methodmame
Traditionally, method coverage measurement was implemented by inserting `trace2` instruction to the head of method iseq. So, it just measured methods defined by `def` keyword. This commit drastically changes the measuring mechanism of method coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t* to runs (i.e., it counts the runs per method entry), and at `Coverage.result`, it creates the result hash by enumerating all `rb_method_entry_t*` objects (by `ObjectSpace.each_object`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-11-07Symptomatic treatment for `rb_thread_terminate_all` freezemame
Under uncertain condition, `rb_thread_terminate_all` gets stuck. `make test-all TESTOPTS="test/ruby/test_gc.rb -n test_interrupt_in_finalizer` fails very rarely (only once every thousand runs). This IS a bug, but seems difficult to fix it soon. This commit makes `rb_thread_terminate_all` wake up every one second, instead of waiting forever, which mitigates the unuseful freeze. This is not an essential solution for the bug, though. I'll create a ticket with how to reproduce the original issue. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60694 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

This is needed for passing to the hook function the measuring target type (line/branch/method) and the site of coverage event fired. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59871 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-09-10move th->machine to ec->machine.ko1
* vm_core.h: move rb_thread_t::machine to rb_execution_context_t::machine. * vm_core.h, gc.c (rb_gc_mark_machine_stack): accept ec instead of th. it enables to call this func from rb_execution_context_mark() in vm.c. * cont.c (fiber_setcontext): catch up this fix. fiber_restore_thread() restores machine stack information too. * gc.c: catch up structure layout changes. * thread.c: ditto. * thread_pthread.c: ditto. * thread_win32.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59825 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-09-03Refactor the internal data format for coverage measurementmame
To prepare new measuring targets: branch and method coverages. So far, iseq->coverage was an array of counts executed for line coverage. Now, it is a three-element array for each measuring target, whose first element is an array for line coverage. The second element is planned for branch coverage, and the third will be for method coverage. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59738 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-08-26thread_win32.c: set thread namenobu
* thread_win32.c (native_set_another_thread_name): set thread name by SetThreadDescription. * win32/win32.c (rb_w32_set_thread_description): dynamically try SetThreadDescription. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59660 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-08-10rename rb_execution_context_t::stack(_size) to vm_stack(_size).ko1
* vm_core.h: Ruby processes run with two stacks, a machine stack and a VM stack. To make it clear, this fix renames rb_execution_context_t::stack(_size) to vm_stack(_size). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59563 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
