Issue #5133 has been updated by matz (Yukihiro Matsumoto). Status changed from Assigned to Rejected `unzip` is not really intuitive with Ruby's OO design.

[ruby-dev:52083] I RECORDED YOU!
by ruby-dev＠ruby-lang.org 31 Mar '24

31 Mar '24

Hello there! Unfortunately, there are some bad news for you. Some time ago your device was infected with my private trojan, R.A.T (Remote Administration Tool), if you want to find out more about it simply use Google. My trojan allowed me to access your files, accounts and your camera. Check the sender of this email, I have sent it from your email account. To make sure you read this email, you will receive it multiple times. You truly enjoy checking out porn websites and watching dirty videos, while having a lot of kinky fun. I RECORDED YOU (through your camera) SATISFYING YOURSELF! After that I removed my malware to not leave any traces. If you still doubt my serious intentions, it only takes couple mouse clicks to share the video of you with your friends, relatives, all email contacts, on social networks, the darknet and to publish all your files. All you need is $1800 USD in Bitcoin (BTC) transfer to my account. After the transaction is successful, I will proceed to delete everything. Be sure, I keep my promises. You can easily buy Bitcoin (BTC) here: https://cex.io/buy-bitcoins https://nexo.com/buy-crypto/bitcoin-btc https://bitpay.com/buy-bitcoin/?crypto=BTC https://paybis.com/ https://invity.io/buy-crypto Or simply google other exchanger. After that send the Bitcoin (BTC) directly to my wallet, or install the free software: Atomicwallet, or: Exodus wallet, then receive and send to mine. My Bitcoin (BTC) address is: 13HAreeSVjLf3aueZXf9zmrS1FmvkF4opS Yes, that's how the address looks like, copy and paste my address, it's (cAsE-sEnSEtiVE). You are given not more than 3 days after you have opened this email. As I got access to this email account, I will know if this email has already been read. Everything will be carried out based on fairness. An advice from me, regularly change all your passwords to your accounts and update your device with newest security patches.

[ruby-dev:52082] [Ruby master Feature#5133] Array#unzip as an alias of Array#transpose
by duerst 22 Mar '24

22 Mar '24

Issue #5133 has been updated by duerst (Martin Dürst). In issue #20336, @matheusrich wrote: ``` * [Feature #5133] Array#unzip as an alias of Array#transpose * Seems a more friendly name for this method (easier if you don't have a strong math background) * It is nice that we can do an operation an reverse it with two similar-named methods: ```rb [1, 2, 3, 4].zip(["a", "b", "c", "d"], ["I", "II", "III", "IV"]) # => [[[1, "a"], "I"], [[2, "b"], "II"], [[3, "c"], "III"], [[4, "d"], "IV"]] [[[1, "a"], "I"], [[2, "b"], "II"], [[3, "c"], "III"], [[4, "d"], "IV"]].unzip # => [[1, 2, 3, 4], ["a", "b", "c", "d"], ["I", "II", "III", "IV"]] ``` It's already alluded in some of the comments above: `transpose` is it's own inverse, so if we define `unzip` as an alias for `transpose`, `unzip` will be its own inverse. The reason Haskell has `zip`/`unzip` as inverses is that `zip` in Haskell converts from two lists to a list of pairs, and `unzip` converts from a list of pairs to a pair of lists. In Haskell, `zip` and `unzip` are inverses (up to (un)currying). In Haskell, the arguments of `zip` are limited to two lists. In Ruby, it's one array as receiver and one or more arrays as arguments. For `transpose`, it's an array of arrays. Only the later is fully generic and thus can be made exactly invertible. ---------------------------------------- Feature #5133: Array#unzip as an alias of Array#transpose https://bugs.ruby-lang.org/issues/5133#change-107431 * Author: mrkn (Kenta Murata) * Status: Assigned * Assignee: mrkn (Kenta Murata) ---------------------------------------- Array#zip の逆は Array#transpose なんですけど、この対応関係が非常に分かり難いなと思いました。 Haskell には zip の逆をやる関数として unzip が用意されています。 unzip という名前は、「zip の逆をやりたい」と思ったときに (transpose よりは) 思い付きやすい名前だと思います。ということで Array#unzip を Array#transpose のエイリアスとして導入してはどうでしょう？以下パッチです: diff --git a/array.c b/array.c index 8caad66..dc411b7 100644 --- a/array.c +++ b/array.c @@ -4720,6 +4720,7 @@ Init_Array(void) rb_define_method(rb_cArray, "reject!", rb_ary_reject_bang, 0); rb_define_method(rb_cArray, "zip", rb_ary_zip, -1); rb_define_method(rb_cArray, "transpose", rb_ary_transpose, 0); + rb_define_alias(rb_cArray, "unzip", "transpose"); rb_define_method(rb_cArray, "replace", rb_ary_replace, 1); rb_define_method(rb_cArray, "clear", rb_ary_clear, 0); rb_define_method(rb_cArray, "fill", rb_ary_fill, -1); -- https://bugs.ruby-lang.org/

[ruby-dev:52076] [Ruby master Bug#16297] calling undefined allocator by `Class.instance_method(:allocate)`
by jhawthorn (John Hawthorn) 01 Mar '24

01 Mar '24

Issue #16297 has been updated by jhawthorn (John Hawthorn). I'm not sure if there's a deeper problem this causes, but it is still possible after this patch to call the allocator on a Rational through defining an arbitrary `allocate` method. ``` ruby >> def Rational.allocate; end => :allocate >> Class.instance_method(:allocate).bind_call(Rational) => (0/1) ``` ---------------------------------------- Bug #16297: calling undefined allocator by `Class.instance_method(:allocate)` https://bugs.ruby-lang.org/issues/16297#change-107083 * Author: nobu (Nobuyoshi Nakada) * Status: Closed * Backport: 2.5: REQUIRED, 2.6: DONE ---------------------------------------- For instance, `Rational.allocate` is undefined. ```ruby Rational.allocate #=> undefined method `allocate' for Rational:Class (NoMethodError) ``` But it can be called by `Class.instance_method(:allocate)`. ```ruby Class.instance_method(:allocate).bind_call(Rational) #=> (0/1) Class.instance_method(:allocate).bind(Rational).call #=> (0/1) ``` These allocators are defined for Marshal, and undefined as methods. -- https://bugs.ruby-lang.org/
