* Transition root fiber into state FIBER_TERMINATED.Samuel Williams2019-06-201-0/+11
| | | | | | | During fork, it's possible that threads with root fibers are terminated, but fiber state is not updated. `fiber_verify` will subsequently fail. We forcefully enter the FIBER_TERMINATED state when terminating the root fiber.
* Ensure that vm_stack is cleared in `thread_cleanup_func_before_exec`.Samuel Williams2019-06-201-9/+2
| | | | | | | | If `vm_stack` is left dangling in a forked process, the gc attempts to scan it, but it is invalid and will cause a segfault. Therefore, we clear it before forking. In order to simplify this, `rb_ec_clear_vm_stack` was introduced.

* ia64: Don't clear register_stack_startJames Clarke2019-04-271-1/+0
| | | | | | | | r59829 stopped clearing stack_start and enabled the code for !FIBER_USE_NATIVE, but we need to do the same for register_stack_start on ia64, otherwise we end up with NULL in cont_save_machine_stack. Closes: https://github.com/ruby/ruby/pull/2155

* Support targetting TracePoint [Feature #15289]ko12018-11-261-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

* fiber: fix crash on GC after forkingnormal2018-09-121-16/+13
| | | | | | | | | | | | | | | | | | Remove the remainder of ROOT_FIBER_CONTEXT use and unnecessary differences between the root and non-root fiber. This makes it easier to follow new root fiber at fork time. Multiple sources of truth often leads to bugs, as in this case. We can determinte root fiber by checking a fiber against the root_fiber of its owner thread. The new `fiber_is_root_p' function supports that. Now, we can care only about free-ing/recycling/munmap-ing stacks as appropriate. [Bug #15050] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64706 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* cont.c (fiber_memsize): do not rely on ROOT_FIBER_CONTEXTnormal2018-09-121-5/+8
| | | | | | | | | | | | | | We can check if the fiber we're interested in is the th->root_fiber for the owner thread, so there is no need to use ROOT_FIBER_CONTEXT. Note: there is no guarantee th->ec points to &th->root_fiber->cont.saved_ec, thus vm::thread_memsize may not account for root fiber correctly (pre-existing bug).

* share VM stack between threads and fibers if identical in sizenormal2018-09-121-10/+20
| | | | | | | | | | | | | ec->vm_stack is always allocated with malloc, so stack cache for root fiber (thread stack) and non-root fibers can be shared as long as the size is the same. The purpose of this change is to reduce dependencies on ROOT_FIBER_CONTEXT.
