36 hoursFix documentation for Enumerator::Lazy#with_indexJeremy Evans
If a block is given, it returns a lazy enumerator that will iterate over the block, it doesn't iterate over the block immediately. Fixes [Bug #17789]

2020-02-09Removed duplicated codeNobuyoshi Nakada
2020-01-02Fully separate positional arguments and keyword argumentsJeremy Evans
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(). Notes: Merged:
2019-12-26decouple internal.h headers卜部昌平
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). Notes: Merged:

2019-12-11Fix Enumerator::Lazy#with_indexJeremy Evans
* Make it correctly handle lambdas * Make it iterate over the block if block is given The original implementation was flawed, based on lazy_set_method instead of lazy_add_method. Note that there is no implicit map when passing a block, the return value of the block passed to with_index is ignored, just as it is for Enumerator#with_index. Also like Enumerator#with_index, when called with a block, the return value is an enumerator without the index. Fixes [Bug #16414] Notes: Merged:
2019-12-03Make Enumerator::Chain#each treat lambdas as lambdaJeremy Evans
Previously, lambdas were converted to procs because of how rb_block_call works. Switch to rb_funcall_with_block, which handles procs as procs and lambdas as lambdas. Fixes [Bug #15613] Notes: Merged:
2019-11-18Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans

2019-09-30Add rb_enumeratorize_with_size_kw and related macrosJeremy Evans
Currently, there is not a way to create a sized enumerator in C with a different set of arguments than provided by Ruby, and correctly handle keyword arguments. This function allows that. The need for this is fairly uncommon, but it occurs at least in Enumerator.produce, which takes arugments from Ruby but calls rb_enumeratorize_with_size with a different set of arguments. Notes: Merged:
2019-09-26Fix more keyword separation issuesJeremy Evans
This fixes instance_exec and similar methods. It also fixes Enumerator::Yielder#yield, rb_yield_block, and a couple of cases with Proc#{<<,>>}. This support requires the addition of rb_yield_values_kw, similar to rb_yield_values2, for passing the keyword flag. Unlike earlier attempts at this, this does not modify the rb_block_call_func type or add a separate function type. The functions of type rb_block_call_func are called by Ruby with a separate VM frame, and we can get the keyword flag information from the VM frame flags, so it doesn't need to be passed as a function argument. These changes require the following VM functions accept a keyword flag: * vm_yield_with_cref * vm_yield * vm_yield_with_block Notes: Merged:
2019-09-26Fix keyword argument separation issues in Enumerator::Generator#eachJeremy Evans
This requires adding rb_proc_call_kw to pass the keyword flag. Notes: Merged:
2019-09-20Handle keyword argument separation for Enumerator#sizeJeremy Evans
When Object#to_enum is passed a block, the block is called to get a size with the arguments given to to_enum. This calls the block with the same keyword flag as to_enum is called with. This requires adding rb_check_funcall_kw and rb_check_funcall_default_kw to handle keyword flags.
2019-09-13Consolidate empty keyword handlingJeremy Evans
Remove rb_add_empty_keyword, and instead of calling that every place you need to add empty keyword hashes, run that code in a single static function in vm_eval.c. Add 4 defines to include/ruby/ruby.h, these are to be used as int kw_splat values when calling the various rb_*_kw functions: RB_NO_KEYWORDS :: Do not pass keywords RB_PASS_KEYWORDS :: Pass final argument (which should be hash) as keywords RB_PASS_EMPTY_KEYWORDS :: Add an empty hash to arguments and pass as keywords RB_PASS_CALLED_KEYWORDS :: Passes same keyword type as current method was called with (for method delegation) rb_empty_keyword_given_p needs to stay. It is required if argument delegation is done but delayed to a later point, which Enumerator does. Use RB_PASS_CALLED_KEYWORDS in rb_call_super to correctly delegate keyword arguments to super method.

2019-09-06Fix keyword argument separation warnings for enumeratorsJeremy Evans
This makes objects created via #to_enum and related methods pass keyword arguments as keywords. To implement this, add a kw_splat member of struct enumerator and struct iter_method_arg, and add rb_block_call_kw, which is the same as rb_block_call_kw with a flag for whether the last argument is keyword options.

2019-09-03Fix Enumerator::Lazy#{to_enum,enum_for} where method is defined in LazyJeremy Evans
Previously, passing to_enum/enum_for a method that was defined in Lazy itself returned wrong results: [1,2,3].to_enum(:map).to_a # => [1, 2, 3] [1,2,3].lazy.to_enum(:map).to_a # => [] I'm not sure why methods that are designed to be lazy do not work with to_enum/enum_for. However, one possible way to work around this bug is to have to_enum/enum_for use the implementation found in Enumerable/Enumerator, which is what this commit does. While this commit works around the problem, it is a band-aid, not a real fix. It doesn't handle aliases of Enumerable::Lazy methods, for instance. A better fix would be appreciated. Notes: Merged:
2019-09-03Make Enumerator::Lazy#with_index be lazyJeremy Evans
