* Clarify Array#- and Array#difference documentationnobu2019-01-151-6/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we are not explicit enough regarding the potentially confusing behavior of `Array#-` and `Array#difference` when it comes to duplicate items within receiver arrays. Although the original documentation for these methods does use an array with multiple instance of the same integers, the explanation for the behavior is actually imprecise. > removing any items that also appear in +other_ary+ Not only does `Array#-` remove any items that also appear in `other_ary` but it also remove any instance of any item in `other_ary`. One may expect `Array#-` to behave like mathematical subtraction or difference when it doesn't. One could be forgiven to expect the following behavior: ```ruby [1,1,2,2,3,3,4,4] - [1,2,3,4] => [1,2,3,4] ``` In reality this is the result: ```ruby [1,1,2,2,3,3,4,4] - [1,2,3,4] => [] ``` I hope that I've prevented this potential confusion with the clarifications in this change. I can offer this as evidence of likeliness for confusion: https://twitter.com/olivierlacan/status/1084930269533085696 I'll freely admit I was surprised by this behavior myself since I needed to obtain an Array with only one instance of each item in the argument array removed.

| | | | | | | | | | | Before this patch, if `reject!` is called on a shared array it can mutate the shared array rather than a copy. This patch marks the array as "going to be modified" so that the shared source array isn't mutated.

| | | | | | | | | | | | | | | Before this patch Array#all? was not implemented in Array class and alternatively Enumerable#all? was used, while #any? has its own method entry in Array class. Similarly, Array#none? and #one? also lacks its own implementation. This patch provides Array-specific implementations for above three methods to enable faster method lookup.

* Use a shared array for the `duparray` instructiontenderlove2018-11-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this example code: ```ruby def foo [1, 2, 3, 4] end ``` The array literal uses a `duparray` instruction. Before this patch, `rb_ary_resurrect` would malloc and memcpy a new array buffer. This patch changes `rb_ary_resurrect` to use `ary_make_partial` so that the new array object shares the underlying buffer with the array stored in the instruction sequences. Before this patch, the new array object is not shared: ``` $ ruby -r objspace -e'p ObjectSpace.dump([1, 2, 3, 4])' "{\"address\":\"0x7fa2718372d0\", \"type\":\"ARRAY\", \"class\":\"0x7fa26f8b0010\", \"length\":4, \"memsize\":72, \"flags\":{\"wb_protected\":true}}\n" ``` After this patch: ``` $ ./ruby -r objspace -e'p ObjectSpace.dump([1, 2, 3, 4])' "{\"address\":\"0x7f9a76883638\", \"type\":\"ARRAY\", \"class\":\"0x7f9a758af900\", \"length\":4, \"shared\":true, \"references\":[\"0x7f9a768837c8\"], \"memsize\":40, \"flags\":{\"wb_protected\":true}}\n" ``` [Feature #15289] [ruby-core:90097] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66095 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
