Also, shared `def_iseq_ptr` instead of copying the main definition of it. vm_core.h: moved `def_iseq_ptr` to this place. added `inline` to avoid compiler warnings since it's not used in some files including vm_core.h. vm_insnhelper.c: moved `def_iseq_ptr` to vm_core.h. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-10-20vm_insnhelper.c: never cache getinstancevariable twicek0kubun
We have several options to ensure there's no race condition between main thread and MJIT thead about IC reference: 1) Give up caching ivar for multiple classes (or multiple versions of the same class) in the same getinstancevariable (This commit's approach) 2) Allocate new inline cache every time Other ideas we could think of couldn't eliminate possibilities of race condition. In 2, it's memory allocation would be slow and it may trigger JIT cancellation frequently. So 1 would be fast for both VM and JIT situations. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65213 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-10-20ext/coverage/: add the oneshot modemame
This patch introduces "oneshot_lines" mode for `Coverage.start`, which checks "whether each line was executed at least once or not", instead of "how many times each line was executed". A hook for each line is fired at most once, and after it is fired, the hook flag was removed; it runs with zero overhead. See [Feature #15022] in detail. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Spurious interrupts from SIGCHLD cause Mutex#sleep (via ConditionVariable#wait) to return early and breaks some use cases. Since these are outside the programs's control with MJIT, we will only consider pending interrupts (e.g. those from Thread#run) and signals which cause a Ruby-level Signal.trap handler to fire as "spurious" wakeups.

2018-08-10insns.def (invokesuper): remove a dummy receiever flag hack for ZSUPERmame
This is just a refactoring. The receiver of "invokesuper" was a boolean to represent if it is ZSUPER or not. This was used in vm_search_super_method to prohibit ZSUPER call in define_method. (It is currently prohibited because of the limitation of the implementation.) This change removes the hack by introducing an explicit flag, VM_CALL_SUPER, to signal the information. Now, the implementation of "invokesuper" is consistent with "send" instruction. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64268 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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.

2018-06-27hijack SIGCHLD handler for internal usenormal
Use a global SIGCHLD handler to guard all callers of rb_waitpid. To work safely with multi-threaded programs, we introduce a VM-wide waitpid_lock to be acquired BEFORE fork/vfork spawns the process. This is to be combined with the new ruby_waitpid_locked function used by mjit.c in a non-Ruby thread. Ruby-level SIGCHLD handlers registered with Signal.trap(:CHLD) continues to work as before and there should be no regressions in any existing use cases. Splitting the wait queues for PID > 0 and groups (PID <= 0) ensures we favor PID > 0 callers. The disabling of SIGCHLD in rb_f_system is longer necessary, as we use deferred signal handling and no longer make ANY blocking waitpid syscalls in other threads which could "beat" the waitpid call made by rb_f_system. We prevent SIGCHLD from firing in normal Ruby Threads and only enable it in the timer-thread, to prevent spurious wakeups from in test/-ext-/gvl/test_last_thread.rb with MJIT enabled. I've tried to guard as much of the code for RUBY_SIGCHLD==0 using C "if" statements rather than CPP "#if" so to reduce the likelyhood of portability problems as the compiler will see more code. We also work to suppress false-positives from Process.wait(-1, Process::WNOHANG) to quiets warnings from spec/ruby/core/process/wait2_spec.rb with MJIT enabled. Lastly, we must implement rb_grantpt for ext/pty. We need a MJIT-compatible way of supporting grantpt(3) which may spawn the `pt_chown' binary and call waitpid(2) on it.

2018-06-06rb_vm_insn_addr2insn: use st to perform addr2insn mappingnormal
The current VM_INSTRUCTION_SIZE is 198, so the linear search painful during a major GC phase. I noticed rb_vm_insn_addr2insn2 showing up at the top of some profiles while working on some malloc-related stuff, so I decided to attack it. Most notably, the benchmark/bm_vm3_gc.rb improves by over 40%: https://80x24.org/spew/20180602220554.GA9991@whir/raw [ruby-core:87361] [Feature #14814] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63594 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-05-23remove VM_ENV_DATA_INDEX_ENV_PROC.ko1
* vm_core.h (VM_ENV_DATA_INDEX_ENV_PROC): ep[VM_ENV_DATA_INDEX_ENV_PROC] is allocated to mark a Proc which is created from iseq block. However, `lep[0]` keeps Proc object itself as a block handler (Proc). So we don't need to keep it. * vm_core.h (VM_ENV_PROCVAL): ditto. * vm.c (vm_make_env_each): do not need to keep blockprocval as special value. * vm.c (vm_block_handler_escape): simply return Proc value. * proc.c (proc_new): we don't need to check Env because a Proc type block handler is a Proc object itself.

rb_atomic_t is 32-bit on 64-bit platforms (including the popular x86-64 Linux), so save 4 bytes on this structure. This doesn't result in any final size reduction due to padding, yet, but future changes are possible to shrink rb_execution_context_t git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63435 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-04-20simplify altstack and enable reuse with thread cachenormal
Instead of allocating and registering the altstack in different places, do it together to reduce code and improve readability. When thread cache is enabled, storing altstack in rb_thread_t is wasteful and we may reuse altstack in the same pthread. This also lets us clearly allow use of xmalloc to allow GC to recover from ENOMEM.
