* Make Array#uniq return subclass instance if called on subclass instanceJeremy Evans2019-09-021-4/+8
| | | | | | | | Previously, Array#uniq would return subclass instance if the length of the array were 2 or greater, and would return Array instance if the length of the array were 0 or 1. Fixes [Bug #7768]
* Avoid confusion in Array#- and Array#difference docs (#2070)Olivier Lacan2019-08-161-6/+6
| | | | | | My previous attempt to correct #2068 apparently failed and the confusing wording ("instances") was merged into trunk instead. This should address any potential confusion.

* array.c: factor out a complex condition of assertYusuke Endoh2019-07-201-2/+8
| | | | | | | | | | | ARY_SHARED_P and ARY_EMBED_P included: assert(!FL_TEST((ary), ELTS_SHARED) || !FL_TEST((ary), RARRAY_EMBED_FLAG)), The two predicate macros are used in many other assert conditions, which caused memory bloat during C compilation. This change factors out the assertion above to a function. Now gcc consumes 160 MB instead of 250 MB to compile array.c.
* array.c: use assert in macro instead of in a functionYusuke Endoh2019-07-191-7/+7
| | | | | The old code lost information of lineno. Now, an assertion error will output a correct lineno (but now gcc 8 requires 250 MB, unfortunately).
* array.c: factor out `assert(RB_TYPE_P(ary, T_ARRAY))` to a functionYusuke Endoh2019-07-191-4/+10
| | | | | | | The assertion blows up gcc 8 by consuming approx. 1.8 GB memory. This change reduces the amount of memory required to about 200 MB. A follow-up of ae750799c1b28b06d02e50cd26450b9903516526.
* Use FL_TEST_RAW() to check flags.Koichi Sasada2019-07-191-10/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FL_TEST() uses FL_ABLE() which test data types. However, in array.c we don't need to check it (all of them should be T_ARRAY), so I changed from FL_TEST() to FL_TEST_RAW() which does not check FL_ABLE(). Instead of FL_ABLE(), add assertion to check given object is a T_ARRAY object. For example, rb_ary_free() becomes slim: with FL_TEST(): 0000000000006a30 <rb_ary_free>: 6a30: 40 f6 c7 07 test $0x7,%dil 6a34: 48 8b 07 mov (%rdi),%rax 6a37: 75 09 jne 6a42 <rb_ary_free+0x12> 6a39: 48 f7 c7 f7 ff ff ff test $0xfffffffffffffff7,%rdi 6a40: 75 1e jne 6a60 <rb_ary_free+0x30> 6a42: a9 00 00 00 02 test $0x2000000,%eax 6a47: 74 07 je 6a50 <rb_ary_free+0x20> 6a49: f3 c3 repz retq 6a4b: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1) 6a50: 48 8b 7f 20 mov 0x20(%rdi),%rdi 6a54: e9 00 00 00 00 jmpq 6a59 <rb_ary_free+0x29> 6a59: 0f 1f 80 00 00 00 00 nopl 0x0(%rax) 6a60: 89 c2 mov %eax,%edx 6a62: 83 e2 1f and $0x1f,%edx 6a65: 83 fa 1b cmp $0x1b,%edx 6a68: 74 d8 je 6a42 <rb_ary_free+0x12> 6a6a: f6 c4 60 test $0x60,%ah 6a6d: 74 d3 je 6a42 <rb_ary_free+0x12> 6a6f: eb d8 jmp 6a49 <rb_ary_free+0x19>``` with FL_TEST_RAW(): 0000000000006a30 <rb_ary_free>: 6a30: 48 f7 07 00 60 00 02 testq $0x2006000,(%rdi) 6a37: 74 07 je 6a40 <rb_ary_free+0x10> 6a39: f3 c3 repz retq 6a3b: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1) 6a40: 48 8b 7f 20 mov 0x20(%rdi),%rdi 6a44: e9 00 00 00 00 jmpq 6a49 <rb_ary_free+0x19>

* fix shared array terminology.Koichi Sasada2019-07-191-53/+62
| | | | | | | | | | | | | | | | | | Shared arrays created by Array#dup and so on points a shared_root object to manage lifetime of Array buffer. However, sometimes shared_root is called only shared so it is confusing. So I fixed these wording "shared" to "shared_root". * RArray::heap::aux::shared -> RArray::heap::aux::shared_root * ARY_SHARED() -> ARY_SHARED_ROOT() * ARY_SHARED_NUM() -> ARY_SHARED_ROOT_REFCNT() Also, add some debug_counters to count shared array objects. * ary_shared_create: shared ary by Array#dup and so on. * ary_shared: finished in shard. * ary_shared_root_occupied: shared_root but has only 1 refcnt. The number (ary_shared - ary_shared_root_occupied) is meaningful.

| | | | | RUBY_ASSERT_ALWAYS(expr) ignores NDEBUG (we cannot remove this assertion).
* Implement Array#minmaxJeremy Evans2019-07-021-0/+21
| | | | | | | | | Array#minmax was previous not implemented, so calling #minmax on array was actually calling Enumerable#minmax. This is a simple implementation of #minmax by just calling rb_ary_min and rb_ary_max, which improves performance significantly. Fixes [Bug #15929]

* 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.

* Mark array as "going to be modified" in `Array#reject!`tenderlove2019-01-081-0/+1
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
