Issue #21163 has been reported by herwin (Herwin W). ---------------------------------------- Feature #21163: Inconsistencies in Kernel.Float compared to other number parsing methods https://bugs.ruby-lang.org/issues/21163 * Author: herwin (Herwin W) * Status: Open ---------------------------------------- Not sure if I consider the following points to be bugs, but they sure did surprise me: Item 1: Hexadecimal is the only prefix accepted If you use the "0x" prefix, your value is parsed as hexadecimal float: ```ruby Float("0x10") # => 16.0 Float("0x0.8") # => 0.5 # Since Ruby 3.4 ``` This is the only accepted prefix, "010" is not parsed as octal, but as decimal 10. "0b10" and "0o10" are parse errors. If "0x" works, I would expect these to work too. Item 2: Inconsistency with String#to_f String#to_f does not parse hexadecimal strings, "0x10".to_f simply returns 0.0. Generally, the methods in Kernel are stricter than the methods on String, so valid input for the Kernel methods yields the same result in the String methods, I think this is the only exception Item 3: Inconsistency with Kernel#Integer ```ruby Integer("0x1_0a") # => 0x10a Float("0x1_0") # => 16.0 # This underscore is accepted Float("0x1_0a") # => ArgumentError ``` Kernel.Float does accept underscores in hexadecimal strings, but only if all values are digits. As soon as there is a `[a-fA-F]` in the input, it is an ArgumentError -- https://bugs.ruby-lang.org/

Issue #19908 has been reported by nobu (Nobuyoshi Nakada). ---------------------------------------- Feature #19908: Update to Unicode 15.1 https://bugs.ruby-lang.org/issues/19908 * Author: nobu (Nobuyoshi Nakada) * Status: Assigned * Priority: Normal * Assignee: duerst (Martin Dürst) * Target version: 3.3 ---------------------------------------- The Unicode 15.1 is released. The current enc-unicode.rb seems to fail because of `Indic_Conjunct_break` properties with values. I'm not sure how these properties should be handled well. `/\p{InCB_Liner}/` or `/\p{InCB=Liner}/` as the comments in that file? https://github.com/nobu/ruby/tree/unicode-15.1 is the former. -- https://bugs.ruby-lang.org/

[ruby-core:120961] [Ruby master Bug#21131] IO.copy_stream: yielded string changes value when duped

Issue #21131 has been reported by chucke (Tiago Cardoso). ---------------------------------------- Bug #21131: IO.copy_stream: yielded string changes value when duped https://bugs.ruby-lang.org/issues/21131 * Author: chucke (Tiago Cardoso) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [x86_64-darwin23] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- I found an odd situation, when using IO.copy_stream with a File writer quack class, where the data passed to #write somehow ends overwritten, despite the instance being duped. class ProcIO def initialize(block) @block = block end # Implementation the IO write protocol, which yield the given chunk to +@block+. def write(data) @block.call(data.dup) data.bytesize end end rng = Random.new(42) body = Tempfile.new("ruby-bug", binmode: true) body.write(rng.bytes(16_385)) body.rewind payload = [] block = ->(data){ payload << data.dup } IO.copy_stream(body, ProcIO.new(block)) body.rewind if payload.join != body.read puts "it's a bug" end if you use the debugger, you'll see that the first yielded chunk has the correct bytes when yielded the first time, but when the second 1 byte chunk is yielded (IO.copy_stream reads in chunks of 16384 bytes), the first chunk string value suddenly changes. This should not happen, as the first yielded chunk was a string duped from the string yielded by IO.copy_stream (which is expected to be a buffer). -- https://bugs.ruby-lang.org/

[ruby-core:121083] [Ruby master Bug#21144] Win32: Use Windows time zone ID as the time zone name if TZ is not set
by nobu (Nobuyoshi Nakada) 16 Mar '25

16 Mar '25

Issue #21144 has been reported by nobu (Nobuyoshi Nakada). ---------------------------------------- Bug #21144: Win32: Use Windows time zone ID as the time zone name if TZ is not set https://bugs.ruby-lang.org/issues/21144 * Author: nobu (Nobuyoshi Nakada) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- ### Problem On Windows, the `Time#zone` uses `_tzname` provided by the runtime library. This is obtained by using `GetTimeZoneInformation`, if the `TZ` environment variable is not set or empty. The problem is that the `StandardName` and `DaylightName` in that information are for UI, and localized. This means that these names may vary across different international editions and language packs, even for the same time zone. ### Solution Use the Windows time zone ID by using `GetDynamicTimeZoneInformation`, which is available since Windows Vista and Windows Server 2008. Since the `TimeZoneKeyName` is the registry key of time zones, the above problem does not occur. This is also mitigate [Bug #20929]. Even it is possible to define non-ascii key name time zone, there is no such name in the standard installations. ### Compatibilities etc - This also changes the result of `Time#inspect`, may not be good for ones who prefer the display names for UI. - There is no way to restore `zone` from `Marshal` data, this does *not* improve. - The PR changes the signature of `ruby_reset_timezone()` and marks internal use only, but this function is declared in `internal/time.h` and probably no problem. -- https://bugs.ruby-lang.org/

[ruby-core:120802] [Ruby master Bug#21092] error building ruby 3.4.1 on cygwin

Issue #21092 has been reported by jeremyd2019 (Jeremy Drake). ---------------------------------------- Bug #21092: error building ruby 3.4.1 on cygwin https://bugs.ruby-lang.org/issues/21092 * Author: jeremyd2019 (Jeremy Drake) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- While building from the release tarball ruby-3.4.1.tar.xz (also confirmed in snapshot-master.tar.gz from Jan 27, 2025), I get the following error: ../ruby-3.4.1/ext/extmk.rb:279:in 'Array#-': no implicit conversion of nil into Array (TypeError) from ../ruby-3.4.1/ext/extmk.rb:279:in 'Object#extmake' from ../ruby-3.4.1/ext/extmk.rb:659:in 'block in <main>' from ../ruby-3.4.1/ext/extmk.rb:653:in 'Array#each' from ../ruby-3.4.1/ext/extmk.rb:653:in '<main>' I have tracked this down to happening when an ext writes a dummy makefile. In this case, that ext is .bundle/gems/syslog-0.2.0. See https://github.com/ruby/syslog/pull/16 for fixing why it is writing a dummy makefile to begin with, but still, it seems like extmk.rb should handle this case gracefully rather than breaking the build. -- https://bugs.ruby-lang.org/

[ruby-core:121183] [Ruby master Bug#21159] `Module#set_temporary_name` should freeze given name

Issue #21159 has been reported by ko1 (Koichi Sasada). ---------------------------------------- Bug #21159: `Module#set_temporary_name` should freeze given name https://bugs.ruby-lang.org/issues/21159 * Author: ko1 (Koichi Sasada) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- I think it is preferable to freeze the name. So `#set_temporary_name` should copy and freeze the name string. ```ruby c = Class.new.set_temporary_name(str = +'<c>') p c #=> <c> str.upcase! p c #=> actual: <C> #=> expected: <c> p c.name.frozen? #=> actual: false #=> expected: true ``` From the Ractor's aspect, shareable modules should refer only immutable string. -- https://bugs.ruby-lang.org/

[ruby-core:121076] [Ruby master Bug#21142] Lazy enumerator `.each_with_index` ignores `.take(0)` before it
by aaronkison (Aaron Kison) 14 Mar '25

Issue #21142 has been reported by aaronkison (Aaron Kison). ---------------------------------------- Bug #21142: Lazy enumerator `.each_with_index` ignores `.take(0)` before it https://bugs.ruby-lang.org/issues/21142 * Author: aaronkison (Aaron Kison) * Status: Open * ruby -v: 3.2.7 * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Minimum code to produce problem: ``` class Numbers; def each; 100.times { yield _1 }; end; include Enumerable; end Numbers.new.lazy.take(0).each_with_index.map { _1 }.to_a ``` Output (at ruby 3.2.7, and 3.3.0): ``` [0, 1, ..., 99] ``` Expected output (and was as at ruby 3.1.4): ``` [] ``` It works when it opposite ordering: `Numbers.new.lazy.each_with_index.take(0).map { _1 }.to_a`. I suspect it may be related to the change here https://github.com/ruby/ruby/pull/11868/files but I'm not familiar with any of that code. It seems like it replaces an allocated index with a counting index, which my hunch is it works for every value except for 0. -- https://bugs.ruby-lang.org/

[ruby-core:121077] [Ruby master Misc#21143] Speficy order of execution const_added vs inherited
by fxn (Xavier Noria) 13 Mar '25

Issue #21143 has been reported by fxn (Xavier Noria). ---------------------------------------- Misc #21143: Speficy order of execution const_added vs inherited https://bugs.ruby-lang.org/issues/21143 * Author: fxn (Xavier Noria) * Status: Open ---------------------------------------- The hooks `const_added` and `inherited` may need to be executed "together". For example, consider: ```ruby module M def self.const_added(cname) = ... class C def self.inherited(subclass) = ... end class D < C; end ``` When `D` is defined, two hooks are set to run, but in which order? Both orders make sense in a way: 1. When `inherited` is called, you can observe that the subclass has a permanent name, ergo it was assigned to a constant, which must me stored in a module. Therefore, the constant was added to said module module before `inherited` was invoked. 1. When `const_added` is called, you can `const_get` the symbol and observe the object is a class, hence with a superclass, hence inheritance already happened. The patch in https://github.com/ruby/ruby/pull/12759 documents and adds a test for (1). Rationale: 1. I believe it would be nice specify this order. 1. Chose (1) because it is how it works today. While the motivation for the patch was formal (to remove an ambiguity), after reflecting about this I realized users of Zeitwerk may depend on this. Zeitwerk uses `const_added` to set autoloads for child constants in namespaces. Thanks to the current order, code can be used in `inherited` hooks normally (it would not be ready if the order was different). -- https://bugs.ruby-lang.org/
