2019-07-10Remove an unused argument of `str_with_class()`KOBAYASHI Shuji
2019-07-05Read/write `MRB_STR_ASCII` flag only when `MRB_UTF8_STRING` is definedKOBAYASHI Shuji
2019-07-04Rename `MRB_STR_NO_UTF` to 'MRB_STR_ASCII`; close #4550Yukihiro "Matz" Matsumoto
In #4550, @shuuji proposed the name name `MRB_STR_NO_MULTI_BYTE` for more precise description. Although I agree that the name name is correct, but the flag means the string does not contain multi byte UTF-8 characters, i.e. all characters fit in the range of ASCII.
2019-07-04Fix heap buffer overflow; ref #4549dearblue
This patch is showed in #4549.
2019-06-29Simplify `mrb_str_aref_m()` and `mrb_str_aref()`dearblue
It is integration with part of argument parsing used in `mrb_str_aset_m()`.
2019-06-29Replace `String#[]=` method by C implementsdearblue
The purpose is to eliminate string objects that are temporarily created during processing.

2019-06-25Fix `String#byteslice` with `MRB_UTF8_STRING` and some edge casesKOBAYASHI Shuji
Example: $ bin/mruby -e ' p "あa".byteslice(1) p "bar".byteslice(3) p "bar".byteslice(4..0) ' Before this patch: "a" "" RangeError (4..0 out of range) After this patch (same as Ruby): "\x81" nil nil

2019-06-22Fix string brakes for one UTF-8 charactordearblue
2019-06-22Change to UTF-8 string reversing with in placedearblue
Reverses UTF-8 strings without allocated heap for working memory. 1. String before reversing: ``` "!yburmの界世" # byte unit [33, 121, 98, 117, 114, 109, 227, 129, 174, 231, 149, 140, 228, 184, 150] ``` 2. Reverse the byte order of each character: ``` [33, 121, 98, 117, 114, 109, 174, 129, 227, 140, 149, 231, 150, 184, 228] ``` 3. Reverse the whole byte order and complete: ``` [228, 184, 150, 231, 149, 140, 227, 129, 174, 109, 114, 117, 98, 121, 33] # string "世界のmruby!" ```

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" ```

2019-05-07Refactor `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`

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.

2018-11-19Remove 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.
