2021-05-24strtod.c: new public domain implementation of `strtod`; ref #5448Yukihiro "Matz" Matsumoto
Instead of using copyrighted `strtod`, now use the public domain implementation of `strtod` by Yasuhiro Matsumoto (@mattn). The function has been renamed to `mrb_float_read()`; ref #5460 as well.

2021-05-22Fix typo in `src/fmt_fp.c` [ci skip]KOBAYASHI Shuji
2021-05-22fp_fmt.c: remove `mrb_float_to_cstr()`.Yukihiro "Matz" Matsumoto
The function was intended to be a utility function for `mruby-sprintf`. The functionality was integrated into `sprintf.c`.
2021-05-22fmt_fp.c: replace with public domain float format routine; ref #5448Yukihiro "Matz" Matsumoto
The original code can be found in `https://github.com/dhylands/format-float`. Changes: - support `double` - support `#` (alt_form) modifier - small refactoring
2021-05-21fmt_fp.c: remove `fmt` argument from `mrb_float_to_str()`.Yukihiro "Matz" Matsumoto
With major refactoring to prepare removing `snprintf(3) calls.
2021-05-21numeric.h: remove 2 functions from `MRB_API`Yukihiro "Matz" Matsumoto
- `mrb_float_to_str()` - `mrb_float_to_cstr()` Both functions will be replaced to support new coming `format-float.c`.
2021-05-20Support load 64-bit integer from mrb format with MRB_32BIT and MRB_INT64KOBAYASHI Shuji
2021-05-17Global renaming regarding `integer` and `float`.Yukihiro "Matz" Matsumoto
Consistent number conversion function names: * `mrb_value` to immediate (C) value * `mrb_int()` -> `mrb_as_int()` * `mrb_to_flo()` -> `mrb_as_float()` * `mrb_value` to `mrb_value` (converted) * `mrb_to_int()' * `mrb_Integer()` - removed * `mrb_Float()` -> `mrb_to_float` Consistent function name (avoid `_flo` suffix): * `mrb_div_flo()` -> `mrb_div_float`
2021-05-17Rename `mrb_fixnum_to_str` to `mrb_integer_to_str`.Yukihiro "Matz" Matsumoto

Mostly for performance reason.
2021-05-14range.c: refactor conditional compilation code.Yukihiro "Matz" Matsumoto

2021-05-11Remove the obsolete term `Fixnum`.Yukihiro "Matz" Matsumoto
Except for compatibility code.
2021-05-06symbol.c: add `Symbol#name` methodYukihiro "Matz" Matsumoto
`Symbol#name` is similar to `#to_s` but returns a frozen string.
2021-05-06symbol.c: rename `sym_name` to `sym_cstr`.Yukihiro "Matz" Matsumoto
2021-05-03Fix whitespace in `src/symbol.c`John Bampton
2021-05-03symbol.c: remove `id2name` reference from documents.Yukihiro "Matz" Matsumoto
2021-05-03symbol.c: remove `Symbol#id2sym`.Yukihiro "Matz" Matsumoto
In the ancient Ruby, symbols are represented by integers. In that era, to get string representation from integers, we used `Integer#id2sym` method. Later, `Symbol` was introduced, and `id2sym` was used for compatibility. Today, no one uses `id2sym` any longer. It is described in ISO 30170:2012 standard but I consider it as a mistake.
2021-05-02array.c: `mrb_ary_shift_m` should be `static`.Yukihiro "Matz" Matsumoto
2021-05-02symbol.c: remove `mrb_sym_static_p()` function that no one use.Yukihiro "Matz" Matsumoto

2021-04-20Remove `MRB_API` from `mrb_get_backtrace` definitionKOBAYASHI Shuji
2021-04-19Merge pull request #5415 from dearblue/unwind-mrb_protectYukihiro "Matz" Matsumoto
Introducing the `mrb_protect_raw()` API function
2021-04-19Introducing the `mrb_protect_raw()` API functiondearblue
The purpose is two-fold: 1. to be able to specify a pointer directly when user data is used When using `mrb_protect()`, it is necessary to allocate objects by `mrb_obj_cptr()` function when using user data. Adding `mrb_protect_raw()` will make it simpler to reimplement `mrbgems/mruby-error`. 2. to correctly unwind callinfo when an exception is raised from a C function defined as a method (the main topic) If a method call is made directly under `mrb_protect()` and a C function is called, control is returned from `mrb_protect()` if an exception occurs there. In this case, callinfo is not restored, so it is out of sync. Moreover, returning to mruby VM (`mrb_vm_exec()` function) in this state will indicate `ci->pc` of C function which is equal to `NULL`, and subsequent `JUMP` will cause `SIGSEGV`. Following is an example that actually causes `SIGSEGV`: - `crash.c` ```c #include <mruby.h> #include <mruby/compile.h> #include <mruby/error.h> static mrb_value level1_body(mrb_state *mrb, mrb_value self) { return mrb_funcall(mrb, self, "level2", 0); } static mrb_value level1(mrb_state *mrb, mrb_value self) { return mrb_protect(mrb, level1_body, self, NULL); } static mrb_value level2(mrb_state *mrb, mrb_value self) { mrb_raise(mrb, E_RUNTIME_ERROR, "error!"); return mrb_nil_value(); } int main(int argc, char *argv[]) { mrb_state *mrb = mrb_open(); mrb_define_method(mrb, mrb->object_class, "level1", level1, MRB_ARGS_NONE()); mrb_define_method(mrb, mrb->object_class, "level2", level2, MRB_ARGS_NONE()); mrb_p(mrb, mrb_load_string(mrb, "p level1")); mrb_close(mrb); return 0; } ``` - compile & run ```console % `bin/mruby-config --cc --cflags --ldflags` crash.c `bin/mruby-config --libs` % ./a.out zsh: segmentation fault (core dumped) ./a.out ``` After applying this patch, it will print exception object and exit normally. The `mrb_protect()`, `mrb_ensure()` and `mrb_rescue_exceptions()` in `mrbgems/mruby-error` have been rewritten using `mrb_protect_raw()`.
