* move rb_thread_t::interrupt_flag and maskko12017-11-061-7/+7

RUBY_VM_CHECK_INTS() accepts `ec` instead of `th`. * cont.c (rb_fiber_terminate): to propagate interrupt information, add new parameter `need_interrupt`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60672 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | * vm_insnhelper.c (ec_stack_overflow): renamed from threadptr_stack_overflow and also rb_ec_stack_overflow is from rb_threadptr_stack_overflow because they accept `ec` instead of `th`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60464 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Use rb_execution_context_t instead of rb_thread_tko12017-10-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* use "enum ruby_tag_type" and TAG_NONE.ko12017-06-231-2/+2
| | | | | | | | | | | | | | | Return value of EXEC_TAG() is saved by "int state". Instead of "int", use "enum ruby_tag_type". First EXEC_TAG() value should be 0, so that define TAG_NONE (= 0) and use it. Some code used "status" instead of "state". To make them clear, rename them to state. We can change variable name from "state" to "tag_state", but this ticket doesn't contain it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59155 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* remove ruby_kill() introduced for [Bug #7951].ko12017-06-121-1/+1

So that `kill(2)' is enough for them. * signal.c (rb_f_kill): ditto. * vm_core.h (rb_thread_t::interrupt_cond): removed because only `ruby_kill()' uses this field. * test/ruby/test_signal.rb: Without this patch sending SIGSTOP to own process wait another interrupt even if another process sends SIGCONT. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59066 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
