Yukihiro "Matz" Matsumoto b8b86d1976 Merge pull request #5535 from dearblue/get-args-frozen 
Checks the frozen object with `mrb_get_args()`
 2021-08-24 16:33:15 +09:00
dearblue 66aa184a82 Checks the frozen object with mrb_get_args() 
This now works with the `+` modifier that can be added after each specifier.

- `nil` is bypassed.
- The `s` and `z` specifiers are received in C as a `const char *`, so adding a `+` modifier will raise an exception.
- The `a` specifier is received in C as `const mrb_value *`, so adding a `+` modifier will raise an exception.
- The `|`, `*`, `&`, `?` and `:` specifiers with `+` modifier raises an exception.

If `!`/`+` exceeds one for each specifier, an exception will occur in the subsequent processing.
This is the same behavior as before.

dearblue 6415faabaa Integrate each element expansion process of the argument 
The previously used `given` variable will be merged into the `pickarg` pointer variable, which points to the argument currently being processed for each loop.

Yukihiro "Matz" Matsumoto 0f36710445 Merge pull request #5536 from dearblue/random-seed 
Stirs internal state when `seed` is set in `Random`
 2021-08-22 12:37:34 +09:00
dearblue 5a57602860 Organize the include of header files 
- `#include <math.h>` is done in `mruby.h`.
  Eliminate the need to worry about the `MRB_NO_FLOAT` macro.

- Include mruby header files before standard header files.
  If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`.

This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.

dearblue 2121b6e689 Stirs internal state when seed is set in Random 
This is to avoid the approximation of `Random#rand` when `seed`s are close together.

For example, the first `#rand` values after doing `Random#srand(0)` and `Random#srand(1)` are very similar.

Below is the sequence of mruby before this patch was given a `seed` of `0...20`:

```console
% bin/mruby -e 'r = Random.new; 20.times { |i| r.srand(i); puts "seed=%2d  %s" % [i, 10.times.map { "%0.3f" % r.rand }.join(" ")] }'

Yukihiro "Matz" Matsumoto 36632f55f4 boxing_word.h: embed mrb_float in mrb_value if possible. 
Embedding reduce memory consumption, sacrificing precision. It clips least
significant 2 bits from `mrb_float`, so if you need to keep float precision,
define `MRB_USE_FLOAT_FULL_PRECISION`.

`MRB_WORD_BOXING` and `MRB_INT64`:

`mrb_float` (`double`) is embedded in `mrb_value` clipped last 2 bits.

`MRB_WORD_BOXING` and `MRB_INT64` and `MRB_USE_FLOAT_FULL_PRECISION`:

`mrb_float` is allocated in the heaps wrapped by `struct RFloat`.

`MRB_WORD_BOXING` and `MRB_INT32` and `MRB_USE_FLOAT32`:

`mrb_float` (`float`) is embedded in `mrb_value` clipped last 2 bits.
In addition, to reserve bit space in the `mrb_value`, maximum inline
symbol length become 4 (instead of 5) in the configuration.

`MRB_WORD_BOXING` and `MRB_INT32`:

Assume `MRB_USE_FLOAT_FULL_PRECISION` and allocate Float values in heap.

Check the class with `I` specifier of `mrb_get_args()`
 2021-08-13 18:11:26 +09:00
dearblue 01da5e1392 Check the class with I specifier of mrb_get_args() 
Previously, the `I` specifier only checked if the object was `MRB_TT_ISTRUCT`.
So it was at risk of getting pointers to different C structs if multiple classes were to use the `MRB_TT_ISTRUCT` instance.

Change this behavior and change the C argument corresponding to the `I` specifier to `(void *, struct RClass)`.

This change is not compatible with the previous mruby.
Please note that if the user uses the previous specifications, `SIGSEGV` may occur or the machine stack may be destroyed.
