Do not create core file if it is intentional abort

2022-01-19T14:17:14+00:00

Two tests abort intentionally and they create core files if
possible. In these case, we don't need to see core files
so disable by `"Process.setrlimit(Process::RLIMIT_CORE, 0)` for
those cases.

Use omit instead of skip: test/ruby/**/*.rb

Deprecate taint/trust and related methods, and make the methods no-ops

2019-11-17T23:00:25+00:00

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.

Wait for the helper thread to terminate

Removed unused variables

thread_pthread.c: main thread always gets hit by signals

2018-08-25T21:59:30+00:00

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

test/ruby/test_signal.rb (test_sigchld_ignore): increase timeout

2018-07-13T03:15:04+00:00

I suspect CI test machine was overloaded at the time,
or swapping at the time due to parallel build with mjit.
