* Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans2019-11-181-5/+0
| | | | | | This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby.

* thread_pthread.c: main thread always gets hit by signalsnormal2018-08-251-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to ensure Signal.trap handlers can function if the main thread is sleeping after a subthread has grabbed sigwait_fd, but later exited. Consider the following timeline: main_thread sub-thread ----------------------------------------- Signal.trap() { ... } get sigwait_fd ppoll on sigwait_fd native_cond_sleep (via pthread_cond_wait) ppoll times-out put sigwait_fd sub-thread exits only thread alive SIGNAL HITS The problem is pthread_cond_wait cannot return EINTR, so we can never run the Signal.trap handler. So we will avoid using native_cond_sleep in the main thread and always use ppoll to sleep when in the main thread. This can guarantee the main thread remains aware of signals; even if it cannot safely read off sigwait_fd git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64538 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* signal.c: preserve trap(:CHLD, "IGNORE") behavior with SIGCHLDnormal2018-07-081-0/+43
| | | | | | | | | We need to preserve "IGNORE" behavior from Ruby 2.5 and earlier. We can't rely on SA_NOCLDWAIT any more, since we always need system() and MJIT to work; so we fake that behavior using dedicated reaper (currently in timer-thread). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63879 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | * thread.c (rbuy_kill): removed. This function is used with SIGSEGV, SIGBUS, SIGKILL, SIGILL, SIGFPE and SIGSTOP and these signals are affect immediately.
