Arch Linux CI still seems to timeout on this test... Note, I can't reproduce the failures in these tests on a FreeBSD 11.1 VM while infinite-looping, even without the "th.join(0.001)". It doesn't seem related to the use of rb_wait_for_single_fd (r64529). cf. https://rubyci.org/logs/rubyci.s3.amazonaws.com/arch/ruby-trunk/log/20180826T090003Z.fail.html.gz git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64543 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-25thread_pthread.c: main thread always gets hit by signalsnormal
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

2018-08-16process.c: defaults to close_others falsenormal
Arbitrarily closing file descriptors on exec breaks use cases where a Ruby process sets up a descriptor for non-Ruby children to use. For example, the "rake foo" target may spawn any number of subprocesses (Ruby or not) which depends on parsing the "FOO" environment variable for out_fd:99 and writing to foo.out FOO=out_fd:99 rake foo 99>>foo.out Unfortunately, this introduced one incompatibility in test/lib/test/unit.rb and it now requires explicitly setting IO#close_on_exec=true [ruby-core:88007] [Misc #14907] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64399 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64340 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-13Support optional inherit argument for Module#method_defined?usa
Module has many introspection methods for methods and constants that either return an array or return true or false for whether the method or constant is defined. Most of these methods support an optional argument that controls whether to consider inheritance. Currently, the following Module methods support such a argument: * const_defined? * constants * instance_methods * private_instance_methods * protected_instance_methods * public_instance_methods and the following methods do not: * method_defined? * private_method_defined? * protected_method_defined? * public_method_defined? This patch supports such an argument for the *method_defined? methods. While you can currently work around the lack of support via: mod.instance_methods(false).include?(:method_name) This patch allows the simpler and more efficient: mod.method_defined?(:method_name, false) One case where you want to exclude inheritance when checking for a method definition is when you want to replace a method that may already exist. To avoid a verbose warning, you want to remove the method only if it is already defined: remove_method(:foo) if method_defined?(:foo, false) define_method(:foo){} You can't call remove_method without checking for the method definition, as that can raise a NameError, and you don't want to include inheritance because remove_method will still raise a NameError if the method is defined by an ancestor and not by the module itself.

2018-08-06enumerator.c: Introduce Enumerator::ArithmeticSequencemrkn
This commit introduces new core class Enumerator::ArithmeticSequence. Enumerator::ArithmeticSequence is a subclass of Enumerator, and represents a number generator of an arithmetic sequence. After this commit, Numeric#step and Range#step without blocks returned an ArithmeticSequence object instead of an Enumerator. This class introduces the following incompatibilities: - You can create a zero-step ArithmeticSequence, and its size is not ArgumentError, but Infinity. - You can create a negative-step ArithmeticSequence from a range.

2018-07-29thread_pthread: remove timer-thread by restructuring GVLnormal
To reduce resource use and reduce CI failure; remove timer-thread. Single-threaded Ruby processes (including forked children) will never see extra thread overhead. This prevents glibc and jemalloc from going into multi-threaded mode and initializing locks or causing fragmentation via arena explosion. The GVL is implements its own wait-queue as a ccan/list to permit controlling wakeup order. Timeslice under contention is handled by a designated timer thread (similar to choosing a "patrol_thread" for current deadlock checking). There is only one self-pipe, now, as wakeups for timeslice are done independently using condition variables. This reduces FD pressure slightly. Signal handling is handled directly by a Ruby Thread (instead of timer-thread) by exposing signal self-pipe to callers of rb_thread_fd_select, native_sleep, rb_wait_for_single_fd, etc... Acquiring, using, and releasing the self-pipe is exposed via 4 new internal functions: 1) rb_sigwait_fd_get - exclusively acquire timer_thread_pipe.normal[0] 2) rb_sigwait_fd_sleep - sleep and wait for signal (and no other FDs) 3) rb_sigwait_fd_put - release acquired result from rb_sigwait_fd_get 4) rb_sigwait_fd_migrate - migrate signal handling to another thread after calling rb_sigwait_fd_put. rb_sigwait_fd_migrate is necessary for waitpid callers because only one thread can wait on self-pipe at a time, otherwise a deadlock will occur if threads fight over the self-pipe. TRAP_INTERRUPT_MASK is now set for the main thread directly in signal handler via rb_thread_wakeup_timer_thread. Originally, I wanted to use POSIX timers (timer_create/timer_settime) for this. Unfortunately, this proved unfeasible as Mutex#sleep resumes on spurious wakeups and test/thread/test_cv.rb::test_condvar_timed_wait failed. Using pthread_sigmask to mask out SIGVTALRM fixed that test, but test/fiddle/test_function.rb::test_nogvl_poll proved there'd be some unavoidable (and frequent) incompatibilities from that approach. Finally, this allows us to drop thread_destruct_lock and interrupt current ec directly. We don't need to rely on vm->thread_destruct_lock or a coherent vm->running_thread on any platform. Separate timer-thread for time slice and signal handling is relegated to thread_win32.c, now.
