Samuel Williams f3462d99a3 Rename `rb_current_thread_scheduler` to `rb_thread_scheduler_if_nonblocking`.
Correctly capture thread before releasing GVL and pass as argument to
`rb_thread_scheduler_if_nonblocking`.

卜部昌平 de3e931df7 add UNREACHABLE_RETURN
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.

卜部昌平 8fc8912109 exec_recursive: do not goto into a branch
I'm not necessarily against every goto in general, but jumping into a
branch is definitely a bad idea.  Better refactor.

Yusuke Endoh 50efa18c6c compile.c: Improve branch coverage instrumentation [Bug #16967]
Formerly, branch coverage measurement counters are generated for each
compilation traverse of the AST.  However, ensure clause node is
traversed twice; one is for normal-exit case (the resulted bytecode is
embedded in its outer scope), and the other is for exceptional case (the
resulted bytecode is used in catch table).  Two branch coverage counters
are generated for the two cases, but it is not desired.

This changeset revamps the internal representation of branch coverage
measurement.  Branch coverage counters are generated only at the first
visit of a branch node.  Visiting the same node reuses the
already-generated counter, so double counting is avoided.

Jeremy Evans 4e1f2283b4 Make Thread#thread_variable? similar to #thread_variable_get
Don't use rb_check_id, which only works for pinned symbols.
Switch inadvertent creation test for thread_variable? to
only check for pinned symbols, same as thread_variable_get
and thread_variable_set.

Make key variable name in thread_local_set match
thread_local_get and thread_variable?.

Koichi Sasada fd0222caed should check pending interrupts correctly.
rb_uninterruptible() disables any interrupts using handle_interrupt
feature (This function is used by `p`).
After this function, pending interrupts should be checked correctly,
however there is no chance to setup interrupt flag of working
threads, it means that nobody checks pending interrupts.
For example, it ignores terminate signal delivered at the end
of main thread and program can't stop.

This patch set interrupt flag if there are pending interrupts.

Jeremy Evans beae6cbf0f Fully separate positional arguments and keyword arguments
This removes the warnings added in 2.7, and changes the behavior
so that a final positional hash is not treated as keywords or
vice-versa.

To handle the arg_setup_block splat case correctly with keyword
arguments, we need to check if we are taking a keyword hash.
That case didn't have a test, but it affects real-world code,
so add a test for it.

This removes rb_empty_keyword_given_p() and related code, as
that is not needed in Ruby 3.  The empty keyword case is the
same as the no keyword case in Ruby 3.

This changes rb_scan_args to implement keyword argument
separation for C functions when the : character is used.
For backwards compatibility, it returns a duped hash.
This is a bad idea for performance, but not duping the hash
breaks at least Enumerator::ArithmeticSequence#inspect.

Instead of having RB_PASS_CALLED_KEYWORDS be a number,
simplify the code by just making it be rb_keyword_given_p().

卜部昌平 5e22f873ed decouple internal.h headers
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).

TIMET_MAX_PLUS_ONE was deleted because the macro was used from only
one place (directly write expression there).

Jeremy Evans ffd0820ab3 Deprecate taint/trust and related methods, and make the methods no-ops
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.

Jeremy Evans c5c05460ac Warn on access/modify of $SAFE, and remove effects of modifying $SAFE
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.

John Hawthorn ebbe396d3c Use ident hash for top-level recursion check
We track recursion in order to not infinite loop in ==, inspect, and
similar methods by keeping a thread-local 1 or 2 level hash. This allows
us to track when we have seen the same object (ex. using inspect) or
same pair of objects (ex. using ==) in this stack before and to treat
that differently.

Previously both levels of this Hash used the object's memory_id as a key
(using object_id would be slow and wasteful). Unfortunately, prettyprint
(pp.rb) uses this thread local variable to "pretend" to be inspect and
inherit its same recursion behaviour.

This commit changes the top-level hash to be an identity hash and to use
objects as keys instead of their object_ids.

I'd like to have also converted the 2nd level hash to an ident hash, but
it would have prevented an optimization which avoids allocating a 2nd
level hash for only a single element, which we want to keep because it's
by far the most common case.

So the new format of this hash is:

{ object => true } (not paired)
{ lhs_object => rhs_object_memory_id } (paired, single object)
{ lhs_object => { rhs_object_memory_id => true, ... } } (paired, many objects)

We must also update pp.rb to match this (using identity hashes).

x * y + z byes.

Jeremy Evans b78a345bd6 Only set RB_PASS_CALLED_KEYWORDS in C functions called directly from Ruby
It is not safe to set this in C functions that can be called from
other C functions, as in the non argument-delegation case, you
can end up calling a Ruby method with a flag indicating keywords
are set without passing keywords.

Introduce some new *_kw functions that take a kw_splat flag and
use these functions to set RB_PASS_CALLED_KEYWORDS in places where
we know we are delegating methods (e.g. Class#new, Method#call)

Yusuke Endoh ce04392d8d Propagate kw_splat information
The kw_splat flag is whether the original call passes keyword or not.
Some types of methods (e.g., bmethod and sym_proc) drops the
information.  This change tries to propagate the flag to the final
callee, as far as I can.
