normal a226434206 process.c: fix ETXTBUSY from MJIT compiler process
This affects test/ruby/test_process.rb (test_execopt_env_path).

Since MJIT uses vfork+execve in a separate thread, there can be
small window in-between vfork and execve where tmp_script.cmd is
held open by the vforked child.  vfork only pauses the MJIT
thread, not any Ruby Threads, so our call to Process.spawn will
hit ETXTBUSY in that window unless we fork.

main thread                       | MJIT thread
----------------------------------------------------
fd = open(tmp)                    |                |
                                  | vfork for CC   |   CC running
write                             |                | ---------------
fchmod                            |                |  sees "fd" here
close(fd)                         |                |
    Process.spawn called          |                |
vfork  (spawn)|    (new process)  |                |
              | execve => TXTBUSY |                |
              |                   |                | execve (FD_CLOEXEC on fd)
              |                   | vfork returns  |

Holding the waitpid_lock whenever we intend to spawn a process
prevents the MJIT thread from spawning a process while we are
spawning in Ruby-land.

It tries to print C backtrace but fails. And core file on the server
seems to be stopping on the irrelevant place due to its own signal
handler for the dump.

And I failed to reproduce this SEGV on my machine.

I don't know why it's broken, so let me try this change to investigate
the reason of SEGV.

normal 6a65f2b1e4 io + socket: make pipes and sockets nonblocking by default
All normal Ruby IO methods (IO#read, IO#gets, IO#write, ...) are
all capable of appearing to be "blocking" when presented with a
file description with the O_NONBLOCK flag set; so there is
little risk of incompatibility within Ruby-using programs.

The biggest compatibility risk is when spawning external
programs.  As a result, stdin, stdout, and stderr are now always
made blocking before exec-family calls.

This change will make an event-oriented MJIT usable if it is
waiting on pipes on POSIX_like platforms.

It is ALSO necessary to take advantage of (proposed lightweight
concurrency (aka "auto-Fiber") or any similar proposal for
network concurrency: https://bugs.ruby-lang.org/issues/13618

Named-pipe (FIFO) are NOT yet non-blocking by default since
they are rarely-used and may introduce compatibility problems
and extra syscall overhead for a common path.

Please revert this commit if there are problems and if I am afk
since I am afk a lot, lately.

* hash.c, internal.h: support theap for small Hash.
  Introduce RHASH_ARRAY (li_table) besides st_table and small Hash
  (<=8 entries) are managed by an array data structure.
  This array data can be managed by theap.
  If st_table is needed, then converting array data to st_table data.

  For st_table using code, we prepare "stlike" APIs which accepts hash value
  and are very similar to st_ APIs.

normal b53fadfd5f process.c: defaults to close_others false
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

normal 708bfd2115 thread_pthread: remove timer-thread by restructuring GVL
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.

normal c6b85fcd01 timer_thread: do not close pipes around fork
There's actually no need to close the pipes used by the
sleepy timer thread before forking, only to stop the timer
thread itself.

Instead, we only close the parent pipes in the child process,
either via close-on-exec flag or when reinitializing the timer
thread.

This change will be necessary when we allow
rb_wait_for_single_fd and rb_thread_fd_select to wait on the
timer_thread_pipe.normal[0] directly and eliminate timer thread.

I don't anticipate compatibility problems with this change
alone.

normal 054a412d54 hijack SIGCHLD handler for internal use
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.

shyouhei 1096be5ac6 passing rb_thread_sleep to rb_protect is IMHO dangerous
rb_thread_sleep's argument is int, while rb_protect expects the function
to take VALUE. Depending on ABI this could be a problem.

We should wrap rb_thread_sleep here.

normal 7e669f40be ruby/ruby.h: remove unnecessary exports from C-API
Needlessly exporting can reduce performance locally and increase
binary size.

Increasing the footprint of our C-API larger is also detrimental
to our development as it encourages tighter coupling with our
internals; making it harder for us to preserve compatibility.

If some parts of the core codebase needs access to globals,
internal.h should be used instead of anything in include/ruby/*.

watson1978 d0015e4ac6 Improve performance of implicit type conversion
To convert the object implicitly, it has had two parts in convert_type() which are
  1. lookink up the method's id
  2. calling the method

Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.

This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

if getrusage(2) is available, to improve precision of Process.times and

  0.343223   0.310037   0.653260 (  0.674025)

On Linux, since struct rusage from getrusage(2) is used instead of struct tms
from times(2), they are slightly improved like:

* Before

Process.times
=> #<struct Process::Tms utime=0.43, stime=0.11, cutime=0.0, cstime=0.0>

puts Benchmark.measure { "a" * 1_000_000_000 }

shyouhei 3106f9412a use HAVE_BUILTIN___BUILTIN_MUL_OVERFLOW
We already check for __builtin_mul_overflow in configure but never
actually referred it before.  Why not call it if available, because
that should render supposedly-optimial assembly outputs.

Optionally if __builtin_mul_overflow_p is available, which is the case
for recent GCC, use that to detect fixnum overflow.  This is much
faster than the previous.  On my machine generated assembly of
numeric.c:int_pow reduces from 480 to 448 bytes, according to nm(1).
Also on my machine, following script boosts from 7.819 to 6.929 sec.

time ./miniruby -e 'i=0; while i < 30_000_000 do i += 1; 7 ** 23; end'

ko1 9f60791a04 * vm_core.h: revisit the structure of frame, block and env.
[Bug #12628]

  This patch introduce many changes.

  * Introduce concept of "Block Handler (BH)" to represent
    passed blocks.

  * move rb_control_frame_t::flag to ep[0] (as a special local
    variable). This flags represents not only frame type, but also
    env flags such as escaped.

  * rename `rb_block_t` to `struct rb_block`.

  * Make Proc, Binding and RubyVM::Env objects wb-protected.

  Check [Bug #12628] for more details.

normal 80a0c0f808 process.c (disable_child_handler_fork_child): simplify
signal(2) is portable for SIG_DFL and SIG_IGN, so we do not
need the extra code for sigaction(2).

Also, execve will reset all signal handlers to default
anyways, so there is little sense in preserving old
signal handler besides SIG_IGN.

Hopefully this makes the code easier-to-understand and
maintain.

normal f224fecc0f improve handling of timer thread shutdown
Shutting down the timer thread now always closes pipes to free FDs.
In fact, we close the write ends of the pipes is done in the main
RubyVM to signal the timer thread shutdown.

To effectively close pipes, we implement userspace locks via
atomics to force the pipe closing thread to wait on any signal
handlers which may be waking up.

While we're at it, improve robustness during resource exhaustion and
allow it to limp along non-fatally if restarting a timer thread
fails.

ngoto d1bce9ec55 * process.c (redirect_close, parent_redirect_close): should not close
reserved FD. It should be closed in the exec system call due to the
  O_CLOEXEC or FD_CLOEXEC flag. [Bug #11353] [ruby-core:69977]
    
* process.c (close_unless_reserved): new function to close FD unless
  it is reserved for internal communication.
      
* thread_pthread.c (rb_reserved_fd_p): should check owner_process pid
  to avoid false positive in forked child process.

ngoto f59356a85a * process.c (rb_execarg_parent_start1): new macro ALWAYS_NEED_ENVP
to generate envp_str anytime on Solaris 10 (or earlier version
  of Solaris) to avoid calling execv() which is async-signal unsafe
  on Solaris 10. [Bug #11265] [ruby-dev:49089]
      
* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
  because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,
  execv() in exec_with_sh() and proc_exec_cmd() are never called.
  To guarantee this, execv() is replaced by a macro to print
  out error message on Solaris 10.
	      
* process.c (proc_exec_sh): Because proc_exec_sh() may be called
  by rb_proc_exec() with envp_str = Qfalse, execl() is replaced
  by a macro that calls execle() with "extern char **environ"
  traditional global variable on Solaris 10.
  TODO: This may be unsafe and sholud be changed
  in the future.
  Although rb_proc_exec() is not used from inside current version
  of ruby, it may be called by third-party extensions.

yugui 57bc5eaf2f Fixes build failures on Portable Native Client.
Note: Some of the fixes are for newlib in general but not NaCl-specific.

* include/ruby/intern.h (rb_fd_select): declare struct timeval, or the
  struct gets local to the function in C99.

* file.c (#include): add nacl/stat.h for PNaCl.
  (utimes): added a declaration for PNaCl.
  (stat_atimespec): stat::st_atimensec is long long but
  timespec::tv_nsec is long in PNaCl.
  (stat_mtimespec, stat_ctimespec): ditto.
  (rb_group_member): disable getgroups unless HAVE_GETGROUPS.
  (eaccess): unify the fallback to generic defined(USE_GETEUID).

* io.c: include sys/time.h for struct timeval.
  (rb_close_before_exec): nothing we can do if F_GETFD is not
  available.
  (ioctl): pnacl newlib actually doesn't have ioctl.

* process.c (maxgroups): it is used iff
   defined(_SC_NGROUPS_MAX) || defined(NGROUPS_MAX) but not
   defined(HAVE_GETGROUPS) || defined(HAVE_SETGROUPS).
  (obj2gid): fail unless the object is a Fixnum if getgrnam is not
  available.
  (disable_child_handler_fork_child): sigaction is not available in
  PNaCl newlib.

* configure.in (warnflags, strict_warnflags): avoid -ansi for strlcpy.
  (rb_cv_gcc_atomic_builtins): also check
  __atomic_or_etch because it is used in ruby_atomic.h.
  (rb_cv_gcc_sync_builtins): ditto.
  (HAVE_GETGRNAM): added.
