2019-07-06Fix missing `#ifndef MRB_ENABLE_ALL_SYMBOLS`KOBAYASHI Shuji
2019-07-05Read/write `MRB_STR_ASCII` flag only when `MRB_UTF8_STRING` is definedKOBAYASHI Shuji
2019-07-04It was too early to check `key` for `undef`; ref #4534Yukihiro "Matz" Matsumoto
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.

2019-06-22Fix 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!" ```

2019-06-22Refine `Hash#rehash` example [ci skip]KOBAYASHI Shuji
Previous example doesn't work because string key (frozen) can't be modified.
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.

- They are not include in Ruby. - Appear in duplicate when `$1`-`$9` are defined.

2019-05-29Add `mrb_alloca` again; ref #4470Yukihiro "Matz" Matsumoto
This time, the allocated memory comes from the string object, which is referenced from GC arena. The memory region will be reclaimed when the C function called from VM is terminated, or the GC arena is restored.

2019-05-26Move `mrb_mod_s_nesting()` to `mruby-metaprog` gem from the coreKOBAYASHI Shuji
2019-05-25Remove `mrb_alloca()` functiondearblue
When I found this function, I expected it to behave the same as the `alloca(3)` function, but it is accually the `mrb_alloca()` function does not free the heap until the `mrb_close()` function is called. Also, even if it is deleted, it can be replaced with the combination of the `MRB_TT_DATA` object and the `mrb_gv_set()` function if it is sure necessary.
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" ```

2019-05-21Export `mrb_int_value` that converts `mrb_float` to `Fixnum`.Yukihiro "Matz" Matsumoto
Or `Float` if `mrb_float` value is too big (or too small) to fit in `mrb_int`. The `_int_` in `mrb_int_value` means `Integral` module, which represents integer-like values in mruby.
2019-05-21Silence the return value warnings from gcc; ref 237a57bYukihiro "Matz" Matsumoto
2019-05-21Move `**`,`/`,`quo`,`div` and comparison methods to Integral from NumericKOBAYASHI Shuji
Having these methods in Numeric can get in the way of creating subclasses of Numeric because they only support Fixnum and Float.
