2019-06-22Replacement to function for string reversingdearblue
2019-06-22Fix potential overflow in `utf8len()`dearblue
For example on 32 bit mode, when `p = 0xfffffffd`, `e = 0xfffffffe` and `len = 4`, the sum of `p` and `len` can be to `1`, and comparison with `e` will to be false. As a result, a segmentation fault occurs by referring to address 0.
2019-05-25Fix double rounded by negative indexdearblue
- Before patched: ``` $ mruby -e 'p (-12..-1).map { |i| "Hello"[i] }.join' "HelloHello" ``` - After patched: ``` $ mruby -e 'p (-12..-1).map { |i| "Hello"[i] }.join' "Hello" ```

2019-05-08Use `mrb_string_value_cstr` in `mrb_str_to_dbl`KOBAYASHI Shuji
2019-05-07Refactor `mrb_str_to_cstr` and `mrb_string_value_cstr`KOBAYASHI Shuji
- Extract null byte check to function. - Avoid string allocation if null byte is included. - Use `str_new` instead of `mrb_str_dup` + `mrb_str_modify`

Functions to add prototypes to headers: * mrb_ary_splice() * mrb_notimplement() * mrb_vformat() * mrb_cstr_to_dbl() * mrb_cstr_to_inum() Functions to be made `static` (`MRB_API` was not needed): * mrb_mod_module_function() * mrb_obj_hash() * mrb_str_len_to_inum() Functions to remove `MRB_API` from definitions (referenced from within `libmruby`): * mrb_mod_cv_defined() * mrb_mod_cv_get() * mrb_f_send()

2018-12-17Recover `String#to_str`; ref #4177Yukihiro "Matz" Matsumoto
We have removed implicit conversion to strings using `to_str`. But some people still using `to_str` as a typical string method, i.e. they do string check by code like: `obj.respond_to?(:to_str)`. So we have recovered the method.
2018-11-19Call `mrb_str_to_str` from `mrb_string_value_ptr` for compatibility.Yukihiro "Matz" Matsumoto
2018-11-19Use type checking `mrb_to_str` instead of converting `mrb_str_to_str`.Yukihiro "Matz" Matsumoto
2018-11-19Remove implicit conversion using `to_str` method; fix #3854Yukihiro "Matz" Matsumoto
We have added internal convenience method `__to_str` which does string type check. The issue #3854 was fixed but fundamental flaw of lack of stack depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA` for workaround.
2018-06-28Use `mrb_raise()` instead of `mrb_raisef()`; ref #4062Yukihiro "Matz" Matsumoto
2018-06-27Add negative check in `mrb_str_resize`; fix #4062Yukihiro "Matz" Matsumoto
2018-05-02Need to call `mrb_str_modify()` in `mrb_str_cat_str()`; fix #4018Yukihiro "Matz" Matsumoto
If `str` and `str2` are the same string object `str->ptr` may be rewritten by `mrb_str_modify()`.

`FrozenError` is a subclass of `RuntimeError` which used to be raised. [Ruby2.5]

Otherwise half-baked string object will be allocated.

2017-11-03Should not use `FSHARED` state for string from `irep` pools; fix #3829Yukihiro "Matz" Matsumoto
This strings in `irep` pools may be freed forcefully in `mrb_irep_free`. This commit probably fixes #3817 as well.

2017-10-01Add new type of shared string: `RSTR_FSHARED`.Yukihiro "Matz" Matsumoto
`RSTR_FSHARED` use frozen strings as shared body instead of `struct mrb_shared_string`. This reduces allocation from literal strings.
