* thread_pthread: remove timer-thread by restructuring GVLnormal2018-07-299-543/+526
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mjit.c: introduce JIT compaction [experimental]k0kubun2018-07-282-15/+121

In the future, it may trigger compaction more frequently and/or limit the maximum times of compaction to prevent unlimited memory usage. So the current behavior is experimental, but at least the performance improvement in this commit won't be removed. === Benchmark === In this benchmark, I'll compare following four conditions: * trunk: r64082 * trunk JIT: r64082 w/ --jit * single-so JIT: This commit w/ --jit * objfcn JIT: This branch https://github.com/k0kubun/ruby/tree/objfcn w/ --jit, which is shinh's objfcn https://github.com/shinh/ruby/tree/objfcn rebased from this commit ``` $ uname -a Linux bionic 4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux ``` * Micro benchmark Using this script https://gist.github.com/k0kubun/10e6d3387c9ab1b134622b2c9d76ef51, calls some amount of different methods that just return `nil`.

* fix range check for Hangul jamo trailers in Unicode normalizationduerst2018-07-282-1/+8
| | | | | | | | | | | | | | | | | | | * lib/unicode_normalize/normalize.rb: Fix the range check for trailing Hangul jamo characters in Unicode normalization. Different from leading or vowel jamos, where LBASE and VBASE are actual characters, a value equal to TBASE expresses the absence of a trailing jamo. This fix is technically correct, but there was no bug because the regular expressions in lib/unicode_normalize/tables.rb eliminate jamos equal to TBASE from normalization processing. * test/test_unicode_normalize.rb: Add preventive test test_no_trailing_jamo based on https://github.com/python/cpython/commit/d134809cd3764c6a634eab7bb8995e3e2eff14d5 just for the case we ever get a regression. This closes issue #14934, thanks to MaLin (Lin Ma) for reporting. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64087 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* thread.c (blocking_region_end): clear ubf before unregister_ubf_listnormal2018-07-281-2/+5
| | | | | | | | | | | | | | | | If we keep ubf set after unregistering, there is a window for other threads (including timer thread) to put this thread back on the ubf_list right away. Entering ubf_list unexpectedly after GVL acquisition may cause spurious wakeup and trigger unexpected behavior. Finally, clear ubf before acquiring GVL, to since ubf is useless during GVL acquisition anyways and we don't want to waste cycles in other threads calling ubf for useless work.
