This freezes the clone even if the receiver is not frozen. It
is only for consistency with freeze: false not freezing the clone
even if the receiver is frozen.
Because Object#clone is now partially implemented in Ruby and
not fully implemented in C, freeze: nil must be supported to
provide the default behavior of only freezing the clone if the
receiver is frozen.
This requires modifying delegate and set, to set freeze: nil
instead of freeze: true as the keyword parameter for
initialize_clone. Those are the two libraries in stdlib that
override initialize_clone.
Implements [Feature #16175]
To pass `false` as `freeze:` keyword argument, `kw_splat` argument
should be true. Also `rb_keyword_given_p()` should return true
here as `false` has been given as a keyword argument.
This makes it possible to initialize_clone to correctly not freeze
internal state if the freeze: false keyword is passed to clone.
If clone is called with freeze: true or no keyword, do not pass
a second argument to initialize_clone to keep backwards
compatibility.
This makes it so that external libraries that override
initialize_clone but do not support the freeze keyword will fail
with ArgumentError if passing freeze: false to clone. I think that
is better than the current behavior, which succeeds but results in
an unfrozen object with frozen internals.
Fix related issues in set and delegate in stdlib.
Fixes [Bug #14266]
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().
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).
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.
If defined in Ruby, dig would be defined as def dig(arg, *rest) end,
it would not use keywords. If the last dig argument was an empty
hash, it could be treated as keyword arguments by the next dig
method. Allow dig to pass along the empty keyword flag if called
with an empty keyword, to suppress the previous behavior and force
treating the hash as a positional argument and not keywords.
Also handle the case where dig calls method_missing, passing the
empty keyword flag to that as well.
This requires adding rb_check_funcall_with_hook_kw functions, so
that dig can specify how arguments are treated. It also adds
kw_splat arguments to a couple static functions.
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)
We can check the function pointer passed to rb_define_private_method
like how we do so in rb_define_method. Doing so revealed some
problematic usages of rb_obj_dummy. They had to be split according
to their arity.
We can check the function pointer passed to rb_define_global_function
like we do so in rb_define_method. It turns out that almost anybody
is misunderstanding the API.
