[ruby-core:121065] [Ruby master Feature#16993] Sets: from hash keys using Hash#key_set
by nobu (Nobuyoshi Nakada) 15 Feb '25

15 Feb '25

Issue #16993 has been updated by nobu (Nobuyoshi Nakada). This kind of extensions should be done in the corresponding library side, set.rb. ---------------------------------------- Feature #16993: Sets: from hash keys using Hash#key_set https://bugs.ruby-lang.org/issues/16993#change-111978 * Author: marcandre (Marc-Andre Lafortune) * Status: Open ---------------------------------------- To create a set from hash keys currently implies a temporary array for all keys, rehashing all those keys and rebuilding a hash. Instead, the hash could be copied and its values set to `true`. ```ruby h = {a: 1} # Now: Set.new(h.keys) # => Set[:a] # After h.key_set # => Set[:a], efficiently. ``` -- https://bugs.ruby-lang.org/

[ruby-core:121050] [Ruby master Feature#16993] Sets: from hash keys using Hash#key_set
by greggzst (Grzegorz Jakubiak) 14 Feb '25

14 Feb '25

Issue #16993 has been updated by greggzst (Grzegorz Jakubiak). I opened a PR to add this functionality https://github.com/ruby/ruby/pull/12750 ---------------------------------------- Feature #16993: Sets: from hash keys using Hash#key_set https://bugs.ruby-lang.org/issues/16993#change-111962 * Author: marcandre (Marc-Andre Lafortune) * Status: Open ---------------------------------------- To create a set from hash keys currently implies a temporary array for all keys, rehashing all those keys and rebuilding a hash. Instead, the hash could be copied and its values set to `true`. ```ruby h = {a: 1} # Now: Set.new(h.keys) # => Set[:a] # After h.key_set # => Set[:a], efficiently. ``` -- https://bugs.ruby-lang.org/

[ruby-core:120335] [Ruby master Feature#20971] Deprecate `rb_path_check`
by Earlopain (Earlopain _) 14 Feb '25

14 Feb '25

Issue #20971 has been reported by Earlopain (Earlopain _). ---------------------------------------- Feature #20971: Deprecate `rb_path_check` https://bugs.ruby-lang.org/issues/20971 * Author: Earlopain (Earlopain _) * Status: Open ---------------------------------------- With #16131, various code around $SAFE, taint, etc. has been deprecated and removed. GH PR https://github.com/ruby/ruby/pull/2476. Now, [`rb_path_check`] still exists as part of the public API, with Ruby itself never using or testing it. I believe it should have been deprecated and was simply missed. Should it be deprecated today or is that not worth the effort? Docs for it are pretty vague: https://github.com/ruby/ruby/blob/33f95d632dce42fac35da29eaed33f0a5a4f0dcb/… > This function is mysterious. What it does is not immediately obvious. Also what it does seems platform dependent. [`rb_path_check`]: https://github.com/ruby/ruby/blob/33f95d632dce42fac35da29eaed33f0a5a4f0dcb/… -- https://bugs.ruby-lang.org/

by herwin (Herwin W) 14 Feb '25

Issue #20982 has been reported by herwin (Herwin W). ---------------------------------------- Feature #20982: Inconsistency between Hash#inspect and ENV.inspect in Ruby 3.4 https://bugs.ruby-lang.org/issues/20982 * Author: herwin (Herwin W) * Status: Open ---------------------------------------- Ruby 3.4 changed the stringified output of Hash to add whitespace to the hashrockets ``` ruby -e 'p({"a"=>"b"})' {"a" => "b"} ``` The output of `ENV.inspect` is very similar to `Hash#inspect`, but does not include the whitespace ``` ruby -e 'p ENV' {"SHELL"=>"/bin/bash", [...] } ``` Adding the extra whitespace around the hashrockets would improve the readability, and make things more consistent. -- https://bugs.ruby-lang.org/
