2019-07-13Change type of a variable for signedness mismatch; ref #4573Yukihiro "Matz" Matsumoto
2019-07-13Avoid `mrb_funcall()` if possible using `mrb_Float()`; ref #4555Yukihiro "Matz" Matsumoto
2019-07-12Fix heap buffer overflow; fix #4569dearblue
2019-07-11Improve performance `String#index` with UTF-8dearblue
Based on Boyer-Moore-Horspool algorithm (Quick Search algorithm). As a side effect, the correct position is returned even if an invalid UTF-8 string is given. ```console % ./mruby@master -e 'p ("\xd1" * 100 + "#").index("#")' 50 % ./mruby@improve-index -e 'p ("\xd1" * 100 + "#").index("#")' 100 ``` The other behavior should be the same as the current implementation.

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!" ```

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.

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.
