[ruby-core:121775] [Ruby Bug#21295] ruby/ruby-dev-builder - macos-13 debug build failures, stops GHA master build updates

Issue #21295 has been reported by MSP-Greg (Greg L). ---------------------------------------- Bug #21295: ruby/ruby-dev-builder - macos-13 debug build failures, stops GHA master build updates https://bugs.ruby-lang.org/issues/21295 * Author: MSP-Greg (Greg L) * Status: Open * ruby -v: master * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- @Eregon [ruby/ruby-dev-builder](https://github.com/ruby/ruby-dev-builder) has issues turned off, which I can understand. It is the repo that creates the Ubuntu & macOS MRI master/head builds used in GHA (GitHub Actions). Recently, there have been test-all failures in the 'macos-13 debug' job. Also, the tests take longer to run than macos-14. I believe macos-13 is x64, macos-14 is arm64. It would certainly be nice to fix the problem. In at least a few workflow runs, it is the only job failure. A more significant issue is that any failure in the workflow's jobs stops a new release from being created. The 'macos-13 debug' jobs have failed on the last two days runs (it . Recently `Set` was updated, I believe it's been a few days, but I don't recall any API changes. I believe no tests were changed/added, but marshalling set was covered in test suites. Hence, that was overlooked, and a subsequent PR/commit fixed it. But, the first commit was done where a new release was created. Since the the 2nd commit was done, all the 'macos-13 debug' jobs have been failing. Hence, it's not available in GHA. So, there are two issues: 1. 'macos-13 debug' is failing test-all 2. ruby/ruby-dev-builder cannot update any master build if one or more of the master builds fail. -- https://bugs.ruby-lang.org/

[ruby-core:121727] [Ruby Feature#21284] Request: add `Array#pad` method

Issue #21284 has been reported by MatzFan (Brian Cohen). ---------------------------------------- Feature #21284: Request: add `Array#pad` method https://bugs.ruby-lang.org/issues/21284 * Author: MatzFan (Brian Cohen) * Status: Open ---------------------------------------- A method to pad an array of arbitrary length with objects up to a specified array size does not currently exist. `Array#fill` does not do this and I therefore propose the following method: ``` ruby class Array def pad(pad_to_length, object = nil) fill(object, size, pad_to_length - size) end end ``` I have provided an [answer](https://stackoverflow.com/a/79591610/4114896) to a Stack Overflow question asking how this can be done in Ruby. I've also explained in a comment on the answer which suggests using `Array#fill` why this does not meet the exact need. -- https://bugs.ruby-lang.org/

[ruby-core:121772] [Ruby Bug#21294] URI.extract is extracting invalid URIs with a mishmash of IPv6 notation with IPv4 address

Issue #21294 has been reported by Keeyan (Keeyan Nejad). ---------------------------------------- Bug #21294: URI.extract is extracting invalid URIs with a mishmash of IPv6 notation with IPv4 address https://bugs.ruby-lang.org/issues/21294 * Author: Keeyan (Keeyan Nejad) * Status: Open * ruby -v: ruby 3.4.3 (2025-04-14 revision d0b7e5b6a0) +PRISM [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- The following is not a valid URI: `http://[127.0.0.1]`. So `URI.extract` should not extract it. It seems it is extracting it, though. So if you have code which extracts all URIs and then parses them, like the following, an error will be raised: ``` ruby require 'uri' URI.extract("Fake URL: http://[127.0.0.1]" , :http).each do |uri| # => ['http://[127.0.0.1]'] URI.parse(uri) # => raise URI::InvalidURIError end ``` ``` /home/keeyan/.local/share/mise/installs/ruby/3.4.3/lib/ruby/3.4.0/uri/rfc3986_parser.rb:130:in 'URI::RFC3986_Parser#split': bad URI (is not URI?): "http://[127.0.0.1]" (URI::InvalidURIError) from /home/keeyan/.local/share/mise/installs/ruby/3.4.3/lib/ruby/3.4.0/uri/rfc3986_parser.rb:135:in 'URI::RFC3986_Parser#parse' from /home/keeyan/.local/share/mise/installs/ruby/3.4.3/lib/ruby/3.4.0/uri/common.rb:212:in 'URI.parse' from test.rb:4:in 'block in <main>' from test.rb:3:in 'Array#each' from test.rb:3:in '<main>' ``` Instead, I believe `URI.extract`, should return an empty array. -- https://bugs.ruby-lang.org/

Issue #21292 has been reported by yahonda (Yasuo Honda). ---------------------------------------- Bug #21292: wrong number of arguments (given 2, expected 0) (ArgumentError) since 8ac8225c504dee57454131e7cde2c47126596fdc https://bugs.ruby-lang.org/issues/21292 * Author: yahonda (Yasuo Honda) * Status: Open * ruby -v: ruby 3.5.0dev (2025-04-25T20:46:05Z master 8ac8225c50) +PRISM [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Rails CI against Ruby master branch has been failing https://buildkite.com/rails/rails-nightly/builds/2129#019673e6-eed1-4ce3-94… According to git bisect, this behavior change has been introduced via 8ac8225c504dee57454131e7cde2c47126596fdc and I think I have managed to reproduce it. ### Steps to reproduce 1. Create foo.rb ```ruby class Foo def initialize @foo = nil end class << self private def method_missing(method_name, ...) Bar.new(self, method_name, ...) end # Workaround for Ruby 3.5.0 # def method_missing(method_name, *args, &block) # Bar.new(self, method_name, *args, &block) # end end end class Bar def initialize(class_name, action, *args) @class_name = class_name @action = action @args = args end end p RUBY_VERSION foo = Foo.hello p foo ``` 2. Run this foo.rb ``` $ ruby foo.rb ``` ### Expected behavior It should show the Ruby version and local variable foo as Ruby 3.4.3 does ```ruby $ ruby -v ruby 3.4.3 (2025-04-14 revision d0b7e5b6a0) +PRISM [x86_64-linux] $ ruby foo.rb "3.4.3" #<Bar:0x00007f130ed47bc8 @class_name=Foo, @action=:hello, @args=[]> $ ``` ### Actual behavior It raises the wrong number of arguments (given 2, expected 0) (ArgumentError) ```ruby $ ruby -v ruby 3.5.0dev (2025-04-25T20:46:05Z master 8ac8225c50) +PRISM [x86_64-linux] $ ruby foo.rb "3.5.0" foo.rb:2:in 'initialize': wrong number of arguments (given 2, expected 0) (ArgumentError) from foo.rb:10:in 'Foo.method_missing' from foo.rb:29:in '<main>' $ ``` ### Additional information 1. To workaround this error, update the method_missing signature as follows. ``` def method_missing(method_name, *args, &block) Bar.new(self, method_name, *args, &block) end ```` 2. This does not reproduce against e0545a0250 that is the parent commit of 8ac8225 ```ruby $ ruby -v ruby 3.5.0dev (2025-04-25T18:04:45Z master e0545a0250) +PRISM [x86_64-linux] $ ruby foo.rb "3.5.0" #<Bar:0x00007f3ac640f8a0 @class_name=Foo, @action=:hello, @args=[]> $ ``` -- https://bugs.ruby-lang.org/

I would like to deprecate `date` via bundled gems for reducing our maintenance time especially @nobu. But `Time.prase` and `Time.strptime` are widely used now. How do we deprecate `date` library? 1. Migrate `Date._strptime`, `Date.strptime` and `Date._parse` to `Time`. The current `Date` is migrated as bundled gems. 2. Migrate `Date` to the bundled gems. `Time.parse` and `Time.strptime` warns if `date` is not found. 3. Keep the current situation 4. ... Does anyone have another idea? -- https://bugs.ruby-lang.org/
