[Misc #18891]
Notes:
Merged: https://github.com/ruby/ruby/pull/6094
|

The altstack memory of a thread may be free'ed even after the VM is
destructed. After that, GC is no longer available, so calling xfree
may lead to a segfault.
This changeset uses the bare free function to free the altstack memory
instead of xfree. [Bug #18126]

iff means if and only if, but readers without that knowledge might
assume this to be a spelling mistake. To me, this seems like
exclusionary language that is unnecessary. Simply using "if and only if"
instead should suffice.

trap can accept blopck/Proc and it can violate Rator isolation,
so the Proc should be isolatable when trap is used on non-main ractor.

This commit introduces Ractor mechanism to run Ruby program in
parallel. See doc/ractor.md for more details about Ractor.
See ticket [Feature #17100] to see the implementation details
and discussions.
[Feature #17100]
This commit does not complete the implementation. You can find
many bugs on using Ractor. Also the specification will be changed
so that this feature is experimental. You will see a warning when
you make the first Ractor with `Ractor.new`.
I hope this feature can help programmers from thread-safety issues.

Not every compilers understand that rb_raise does not return. When a
function does not end with a return statement, such compilers can issue
warnings. We would better tell them about reachabilities.

I'm not necessarily against every goto in general, but jumping into a
branch is definitely a bad idea. Better refactor.

Split ruby.h

A new (not-initialized-yet) pthread attempts to allocate sigaltstack by
using xmalloc. It may cause GC, but because the thread is not
initialized yet, ruby_native_thread_p() returns false, which leads to
"[FATAL] failed to allocate memory" and exit.
In fact, we can observe the error message in the log of OpenBSD CI:
https://rubyci.org/logs/rubyci.s3.amazonaws.com/openbsd-current/ruby-master/log/20200306T083005Z.log.html.gz
This changeset allocates sigaltstack before pthread is created.

Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

rb_eval_cmd takes a safe level, and now that $SAFE is deprecated,
it should be deprecated as well.
Replace with rb_eval_cmd_kw, which takes a keyword flag. Switch
the two callers to this function.

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.

This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.

On Android, a signal handler that is not SIG_DFL is set by default for
SIGSEGV. Ruby's install_sighandler inserts Ruby's handler only when the
signal has no handler, so it does not insert Ruby's SEGV report handler,
which caused some test failures.
This changeset forces to install Ruby's handler for some fatal signals
(sigbus, sigsegv, and sigill). They keep the original handlers, and
call them when the interpreter receives the signals.
|
|
Just refactoring.
The name "rb_bug_context" is completely unclear for me.
(Can you see that "context" means "machine register context"?)
The context is available only when a fatal signal (sigbus, sigsegv, or
sigill) is received; in fact, the function is used only for fatal
signals. So, I think the name should be changed.
|
|
The three functions for fatal signals, sigbus, sigsegv, and sigill, are
a family. The definition of ruby_abort had interrupted them for no
reason. This change just moves the definition after the family.

MINSIGSTKSZ is unsigned int in OpenBSD, which makes a warning of
comparison:
```

We can check the function pointer passed to rb_define_module_function
like how we do so in rb_define_method. The difference is that this
changeset reveales lots of atiry mismatches.

to suppress a warning.

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.
