2020-08-05Merge pull request #5058 from dearblue/benchmarkYukihiro "Matz" Matsumoto
Improve `rake benchmark`
2020-08-04Improve `rake benchmark`dearblue
- Use POSIX format instead of GNU extension for `time` command. For example FreeBSD's `time(1)` does not have GNU extensions available. - Sort `benchmark/bm_*.rb`. This is because the order of the bar graph cannot be uniquely determined depending on the result of `Dir.glob`.

2020-07-31Fix `puts` in `mruby-print` on no argument; 0e9bd24Yukihiro "Matz" Matsumoto
`puts` should print newline when called without arguments.
2020-07-29Use type tag for hash code in `ht_hash_func()`2.1.2-rc2KOBAYASHI Shuji
The function corresponding to `ht_hash_func()` was as follows in the days of khash implementation (before d78acc7a). ```c mrb_hash_ht_hash_func(mrb_state *mrb, mrb_value key) { enum mrb_vtype t = mrb_type(key); ... switch (t) { ... default: hv = mrb_funcall(mrb, key, "hash", 0); h = (khint_t)t ^ (khint_t)mrb_fixnum(hv); break; } ... } ``` When switched to the segmented list implementation (d78acc7a), this function was changed as follows. ```c sg_hash_func(mrb_state *mrb, seglist *t, mrb_value key) { enum mrb_vtype tt = mrb_type(key); ... switch (tt) { ... default: hv = mrb_funcall(mrb, key, "hash", 0); h = (size_t)t ^ (size_t)mrb_fixnum(hv); break; } ... } ``` Since the argument `t` was added, the variable for type tag was changed from `t` to `tt`, but the variable used in the expression of `h` remained `t`. Probably this is an omission of change, so fixed it.

2020-07-24Change the logic to calculate object (`iv_tbl`) size; #5045Yukihiro "Matz" Matsumoto
2020-07-24Merge pull request #5045 from dearblue/memsize_ofYukihiro "Matz" Matsumoto
Improve `mruby-os-memsize`
2020-07-24Improve prototype for `mrb_objspace_page_slot_size()`; ref #5032dearblue
If it qualify a return type that is not a pointer with `const`, the compiler ignores it.
2020-07-24Avoid using FPU with `mruby-os-memsize`; ref #5032dearblue
And, in the calculation of the instance variable size, the fraction was always rounded down because of division of integers, so fix it. At the same time, test items that are no longer passed due to this change are deleted.
2020-07-24Support without `mruby-method` for `mruby-os-memsize`; ref #5032dearblue
2020-07-24Add NUL terminator to string object size calculation; ref #5032dearblue

2020-07-23Fix a bug with `ht_index` called with `size==0`; fix #5046Yukihiro "Matz" Matsumoto
It happens when a hash made empty calls `rehash`.

2020-07-22Use more `mrb_field_write_barrier` for instance variables.Yukihiro "Matz" Matsumoto
2020-07-22Use more local variables.Yukihiro "Matz" Matsumoto
To make debugging easy, and to improve the performance little bit.
2020-07-22Move `gray_list` update from `gc_mark_children`.Yukihiro "Matz" Matsumoto
The responsibility moved to caller to avoid confusion. Currently the function is called from only 2 places, so it is relatively easy to ensure not to update `gray_list` in the caller. But the assumption may change in the future.
2020-07-22Avoid using `mrb_ary_modify` from the internal function.Yukihiro "Matz" Matsumoto
`mrb_ary_modify` calls `mrb_write_barrier`, so can cause the same problem of the past `push`. It is provided for use-level API.
2020-07-22Use `mrb_field_write_barrier` instead of `mrb_write_barrier` for `push`.Yukihiro "Matz" Matsumoto
When the array is very big, the simpler `mrb_write_barrier` causes calling `gc_mark_children` for big arrays repeatedly. That would hinder performance very badly.
2020-07-22Define `Array#to_a` to avoid unnecessary loops.Yukihiro "Matz" Matsumoto
2020-07-22Small comment fix in `mrblib/array.c`.Yukihiro "Matz" Matsumoto
