Stirs internal state when `seed` is set in `Random`
2021-08-21Stirs internal state when `seed` is set in `Random`dearblue
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 seed= 1 0.643 0.585 0.198 0.607 0.370 0.605 0.633 0.593 0.395 0.439 seed= 2 0.643 0.585 0.197 0.981 0.652 0.730 0.875 0.713 0.529 0.269 seed= 3 0.643 0.585 0.198 0.857 0.934 0.730 0.960 0.216 0.286 0.523 seed= 4 0.643 0.585 0.197 0.231 0.217 0.605 0.959 0.958 0.478 0.482 seed= 5 0.643 0.585 0.197 0.106 0.249 0.605 0.044 0.330 0.925 0.047 seed= 6 0.643 0.585 0.197 0.481 0.781 0.731 0.285 0.960 0.804 0.725 seed= 7 0.643 0.585 0.197 0.356 0.813 0.731 0.370 0.711 0.937 0.448 seed= 8 0.643 0.585 0.198 0.732 0.329 0.108 0.243 0.974 0.766 0.936 seed= 9 0.643 0.585 0.198 0.607 0.611 0.108 0.827 0.102 0.962 0.597 seed=10 0.643 0.585 0.198 0.981 0.393 0.233 0.569 0.723 0.472 0.805 seed=11 0.643 0.585 0.198 0.857 0.676 0.233 0.154 0.222 0.603 0.371 seed=12 0.643 0.585 0.198 0.231 0.458 0.108 0.654 0.979 0.928 0.577 seed=13 0.643 0.585 0.198 0.106 0.490 0.108 0.239 0.355 0.749 0.831 seed=14 0.643 0.585 0.198 0.481 0.523 0.233 0.981 0.486 0.505 0.131 seed=15 0.643 0.585 0.198 0.356 0.555 0.234 0.565 0.233 0.011 0.666 seed=16 0.643 0.585 0.197 0.730 0.573 0.611 0.904 0.512 0.971 0.153 seed=17 0.643 0.585 0.197 0.605 0.855 0.611 0.240 0.636 0.041 0.509 seed=18 0.643 0.585 0.196 0.979 0.137 0.736 0.229 0.765 0.674 0.832 seed=19 0.643 0.585 0.197 0.855 0.420 0.736 0.566 0.268 0.183 0.219 ```

2021-08-21boxing_word.h: embed `mrb_float` in `mrb_value` if possible.Yukihiro "Matz" Matsumoto
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()`
2021-08-13Check the class with `I` specifier of `mrb_get_args()`dearblue
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. resolve #5527

Expose all header files of the gems for small compilation
2021-08-09Expose all header files of the gems for small compilationdearblue
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.
