[ruby-core:118823] [Ruby master Bug#20670] fork deadlocks in child process due to timer thread
by jhawthorn (John Hawthorn) 22 Mar '25

Issue #20670 has been reported by jhawthorn (John Hawthorn). ---------------------------------------- Bug #20670: fork deadlocks in child process due to timer thread https://bugs.ruby-lang.org/issues/20670 * Author: jhawthorn (John Hawthorn) * Status: Open * ruby -v: ruby 3.3.4 (2024-07-09 revision be1089c8ec) [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- We've been seeing an occasional failure in the Rails CI related to a test which forks and I managed to reduce it to the following reproduction. ``` ruby Thread.new do loop { sleep 0.0001 } end 1000.times do pid = fork{} Process.waitpid(pid) rescue Exception Process.kill(:KILL, pid) raise end ``` This hangs on Ruby 3.3 and HEAD (_fairly_ reliably), but completes always on Ruby 3.2 In a debugger it seems like the timer thread acquires `vm->ractor.sched.lock` in the parent process just as the process is forking. The child process then ends up stuck inside of `thread_sched_atfork` when trying to acquire the same lock. I've opened https://github.com/ruby/ruby/pull/11356 with a fix -- https://bugs.ruby-lang.org/

[ruby-core:121205] [Ruby master Feature#21163] Inconsistencies in Kernel.Float compared to other number parsing methods
by herwin (Herwin W) 19 Mar '25

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
by chucke (Tiago Cardoso) 16 Mar '25

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/

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/
