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(" ")] }'
seed= 0  0.643 0.585 0.198 0.732 0.087 0.605 0.548 0.468 0.573 0.966

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.

Yukihiro "Matz" Matsumoto 3909281126 Merge pull request #5524 from dearblue/gem-headers 
Expose all header files of the gems for small compilation
 2021-08-10 06:21:18 +09:00
dearblue 4c25ace8b3 Expose all header files of the gems for small compilation 
After building mruby, if the user compiles and links to `libmruby.a`, expose the included directory of the captured gems.
This is a change to the `<build-dir> /lib/libmruby.flags.mak` file and will result in being added to `bin/mruby-config --cflags`.
This eliminates the need for the user to look up the path and add the compiler flag if the user wants to take advantage of her gems publishing features.

In the main build with `rake CONFIG=...`, there is no problem because it can only be seen from the gems that depends directly and indirectly as before.
However, when compiling independently by the user using `bin/mruby-config`, a header file name collision may occur if a unique header directory is added.
