2021-03-17hash.c: `Hash#shift` to return `nil` when a hash is empty.Yukihiro "Matz" Matsumoto
It used to be return the default value if available, but it should ignore the default value for behavior consistency. CRuby will adopt this behavior too in the future. [ruby-bugs:16908]

2020-11-10Reduce memory usage of Hash objectKOBAYASHI Shuji
## Implementation Summary * Change entry list from segmented list to flat array. * Change value of hash bucket from pointer to entry to index of entry list, and represent it by variable length bits according to capacity of hash buckets. * Store management information about entry list and hash table to `struct RHash` as much as possible. ## Benchmark Summary Only the results of typical situations on 64-bit Word-boxing are present here. For more detailed information, including consideration, see below (although most of the body is written in Japanese). * https://shuujii.github.io/mruby-hash-benchmark ### Memory Usage Lower value is better. | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 344B | 256B | 0.74419x | | 40 | 1,464B | 840B | 0.57377x | | 200 | 8,056B | 3,784B | 0.46971x | | 500 | 17,169B | 9,944B | 0.57949x | ### Performance Higher value is better. #### `mrb_hash_set` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 1.41847M i/s | 1.36004M i/s | 0.95881x | | 40 | 0.39224M i/s | 0.31888M i/s | 0.81296x | | 200 | 0.03780M i/s | 0.04290M i/s | 1.13494x | | 500 | 0.01225M i/s | 0.01314M i/s | 1.07275x | #### `mrb_hash_get` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 26.05920M i/s | 30.19543M i/s | 1.15872x | | 40 | 44.26420M i/s | 32.75781M i/s | 0.74005x | | 200 | 44.55171M i/s | 31.56926M i/s | 0.70860x | | 500 | 39.19250M i/s | 29.73806M i/s | 0.75877x | #### `mrb_hash_each` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 25.11964M i/s | 30.34167M i/s | 1.20789x | | 40 | 11.74253M i/s | 13.25539M i/s | 1.12884x | | 200 | 2.01133M i/s | 2.97214M i/s | 1.47770x | | 500 | 0.87411M i/s | 1.21178M i/s | 1.38631x | #### `Hash#[]=` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.50095M i/s | 0.56490M i/s | 1.12764x | | 40 | 0.19132M i/s | 0.18392M i/s | 0.96129x | | 200 | 0.03624M i/s | 0.03256M i/s | 0.89860x | | 500 | 0.01527M i/s | 0.01236M i/s | 0.80935x | #### `Hash#[]` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 11.53211M i/s | 12.78806M i/s | 1.10891x | | 40 | 15.26920M i/s | 13.37529M i/s | 0.87596x | | 200 | 15.28550M i/s | 13.36410M i/s | 0.87430x | | 500 | 14.57695M i/s | 12.75388M i/s | 0.87494x | #### `Hash#each` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.30462M i/s | 0.27080M i/s | 0.88898x | | 40 | 0.12912M i/s | 0.11704M i/s | 0.90642x | | 200 | 0.02638M i/s | 0.02402M i/s | 0.91071x | | 500 | 0.01066M i/s | 0.00959M i/s | 0.89953x | #### `Hash#delete` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 7.84167M i/s | 6.96419M i/s | 0.88810x | | 40 | 6.91292M i/s | 7.41427M i/s | 1.07252x | | 200 | 3.75952M i/s | 7.32080M i/s | 1.94727x | | 500 | 2.10754M i/s | 7.05963M i/s | 3.34970x | #### `Hash#shift` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 14.66444M i/s | 13.18876M i/s | 0.89937x | | 40 | 11.95124M i/s | 11.10420M i/s | 0.92913x | | 200 | 5.53681M i/s | 7.88155M i/s | 1.42348x | | 500 | 2.96728M i/s | 5.40405M i/s | 1.82121x | #### `Hash#dup` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.15063M i/s | 5.37889M i/s | 35.71024x | | 40 | 0.06515M i/s | 3.38196M i/s | 51.91279x | | 200 | 0.01359M i/s | 1.46538M i/s | 107.84056x | | 500 | 0.00559M i/s | 0.75411M i/s | 134.88057x | ### Binary Size Lower value is better. | File | Baseline | New | Factor | |:-----------|--------------:|--------------:|----------:| | mruby | 730,408B | 734,176B | 1.00519x | | libmruby.a | 1,068,134B | 1,072,846B | 1.00441x | ##

2020-11-02Replace `R-assignment` by `single-line pattern matching`.Yukihiro "Matz" Matsumoto
Since `R-assignment` in CRuby is abandoned. Single-line pattern matching in `mruby` only matches single local variable at the moment. Currently it works as a right assignment to a local variable. It will be enhanced in the future.

2020-10-12Always add trailing `.0` in `Float#inspect`; ref #4225KOBAYASHI Shuji
Trailing `.0` is removed from `Float#to_s` and `Float#inspect` at 9d08025b. However, I think the more human-readable format is better for `Float#inspect`. For example, in the `Float#to_s` format, the failure message is not well understood when testing values including types by `eql?` (e.g. `Numeric#step` test). ```ruby assert "example" do exp = 1.0 act = 1 assert_operator(exp, :eql?, act) #=> Expected 1 to be eql? 1. end ```
