Yukihiro "Matz" Matsumoto bf523b71d1 strtod.c: new public domain implementation of strtod; ref #5448 
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.

Yukihiro "Matz" Matsumoto 5eebbd7df2 Global renaming regarding integer and float. 
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`

Yukihiro "Matz" Matsumoto 0c8cd60097 symbol.c: remove id2name reference from documents. 2021-05-03 15:33:39 +09:00
Yukihiro "Matz" Matsumoto ce054bd078 symbol.c: remove Symbol#id2sym. 
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.

Yukihiro "Matz" Matsumoto ff366b65eb Merge pull request #5415 from dearblue/unwind-mrb_protect 
Introducing the `mrb_protect_raw()` API function
 2021-04-19 22:34:20 +09:00
dearblue 891e852286 Introducing the mrb_protect_raw() API function 
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()`.
