[ruby-core:123445] [Ruby Bug#21631] Backport openssl gem bugfix releases

Issue #21631 has been reported by Bo98 (Bo Anderson). ---------------------------------------- Bug #21631: Backport openssl gem bugfix releases https://bugs.ruby-lang.org/issues/21631 * Author: Bo98 (Bo Anderson) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- The openssl gem has made new patch releases for all supported release lines in order to fix a compatibility issue with OpenSSL 3.6.0 (along with other bug fixes such as one for a segfault). Without the compatibility fix, the openssl gem is largely broken for certificate verification with OpenSSL 3.6.0, which then affects other parts of Ruby like net-http. Ruby 3.4 PR (3.3.0 -> 3.3.1): https://github.com/ruby/ruby/pull/14792 Ruby 3.3 PR (3.2.0 -> 3.2.2): https://github.com/ruby/ruby/pull/14793 I'm not entirely sure what to do for Ruby 3.2. We can update the gem from 3.1.0 to 3.1.2 but that's perhaps out-of-scope for Ruby 3.2 being in security maintenance mode. Would cherry-picking the single compatibility fix commit be acceptable? The issue has been widely noticed already: https://github.com/ruby/openssl/issues/949 -- https://bugs.ruby-lang.org/

[ruby-core:123464] [Ruby Bug#21635] Reading code from STDIN unexpectedly sets $_ in 3.4.6+

Issue #21635 has been reported by sisyphus (Sisyphus P). ---------------------------------------- Bug #21635: Reading code from STDIN unexpectedly sets $_ in 3.4.6+ https://bugs.ruby-lang.org/issues/21635 * Author: sisyphus (Sisyphus P) * Status: Open * ruby -v: ruby 3.4.6 (2025-09-16 revision dbd83256b1) +PRISM [arm64-darwin23] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- It seems from Ruby 3.4.6+ if you pass in code that doesn't end with a newline to the ruby interpreter it sets `$_`: ``` # ruby -v ruby 3.4.6 (2025-09-16 revision dbd83256b1) +PRISM [arm64-darwin23] # printf 'p $_' | ruby "p $_" ``` This only happens if the code passed in doesn't end with a newline and doesn't happen in ruby 3.4.5 or earlier: ``` # ruby -v ruby 3.4.5 (2025-07-16 revision 20cda200d3) +PRISM [arm64-darwin23] # printf 'p $_' | ruby nil ``` I would expect that `$_` is nil at the start of program execution. NB. this does result in the world's shortest Ruby quine (`printf 'print' | ruby`) -- https://bugs.ruby-lang.org/

[ruby-core:123456] [Ruby Feature#15590] Add dups to Array to find duplicates
by dpepper (Daniel Pepper) 09 Oct '25

09 Oct '25

Issue #15590 has been updated by dpepper (Daniel Pepper). I stumbled upon this thread during my own quest to find duplicates in an array. Here's a PR to create `Array#duplicates?`. If that gains any traction, maybe we could follow with `Array#duplicates` to return the actual list of duplicate elements, which seems of interest to this group. https://github.com/ruby/ruby/pull/14805 ---------------------------------------- Feature #15590: Add dups to Array to find duplicates https://bugs.ruby-lang.org/issues/15590#change-114825 * Author: xdmx (Eric Bloom) * Status: Open ---------------------------------------- Many times I find myself debugging data and the need of finding duplicated values inside of an Array. Based on the amount of data it could be a simple `array.detect { |value| array.count(value) > 1 }` or a more performant way like ```ruby def dups_for(array) duplicated_values = [] tmp = {} array.each do |value| duplicated_values << value if tmp[value] tmp[value] = true end duplicated_values end ``` It would be awesome if there was a way directly from the core language to call `dups` (or another name, as it could be too similar to the current `dup`) on an array in order to get all the duplicated values. I'd love to create a PR for this, but my C level is non-existent 😞 -- https://bugs.ruby-lang.org/

[ruby-core:123455] [Ruby Feature#7845] Strip doesn't handle unicode space characters in ruby 1.9.2 & 1.9.3 (does in 1.9.1)
by TALlama (Seth Roby) 09 Oct '25

09 Oct '25

Issue #7845 has been updated by TALlama (Seth Roby). matz (Yukihiro Matsumoto) wrote in #note-17: > That indicates the need for something like (({str.strip(:ascii)})), or opposite (({str.strip(:utf8)})) This issue has been dormant for many years, and Ruby has made a lot of changes to be use UTF-8 defaults while the world has steadily moved in that direction. Should we bring this back into consideration as a fix worth making? It certainly blindsided me, and I've been using Ruby since before this ticket was new. ---------------------------------------- Feature #7845: Strip doesn't handle unicode space characters in ruby 1.9.2 & 1.9.3 (does in 1.9.1) https://bugs.ruby-lang.org/issues/7845#change-114824 * Author: timothyg56 (Timothy Garnett) * Status: Open ---------------------------------------- Strip and associated methods in ruby 1.9.2 and 1.9.3 do not remove leading/trailing unicode space characters (such as non-breaking space \u00A0 and ideographic space \u3000) unlike ruby 1.9.1. I'd expect the 1.9.1 behavior. Looking at the underlying native lstrip! and rstrip! methods it looks like this is because 1.9.1 uses rb_enc_isspace() whereas 1.9.2+ uses rb_isspace(). 1.9.1p378 :001 > "\u3000\u00a0".strip => "" 1.9.2p320 :001 > "\u3000\u00a0".strip => "　 " 1.9.3p286 :001 > "\u3000\u00a0".strip => "　 " -- https://bugs.ruby-lang.org/
