Issue #21180 has been reported by alanwu (Alan Wu). ---------------------------------------- Bug #21180: SEGV while marking `imemo_env->iseq` https://bugs.ruby-lang.org/issues/21180 * Author: alanwu (Alan Wu) * Status: Open * Backport: 3.1: DONTNEED, 3.2: REQUIRED, 3.3: REQUIRED, 3.4: REQUIRED ---------------------------------------- This issue happens most realistically for people using a fiber scheduler (through e.g. the *async* gem), on Ruby 3.4.x and on Linux, but the following crashes for me for 3.2 and newer on macOS: ``` $ tail -n +1 test.rb ret1.rb ==> test.rb <== require 'continuation' module Warning def self.warn(message) GC.stress = true callcc end end require_relative 'ret1' ==> ret1.rb <== return 1 ``` Keywords for people searching: `rb_imemo_mark_and_move`, `Note that the Fiber scheduler is enabled`. I have a fix for this and will submit a pull request shortly. -- 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

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/

Issue #21185 has been reported by jeromepl (Jerome Parent-Levesque). ---------------------------------------- Bug #21185: Range#overlap? is not commutative with doubly-unbounded range argument. https://bugs.ruby-lang.org/issues/21185 * Author: jeromepl (Jerome Parent-Levesque) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- In https://bugs.ruby-lang.org/issues/20725 the following: ``` ruby (nil..nil).overlap?(..3) ``` was fixed to output `true` instead of `false`. However, when reversing the order of the arguments the output is wrong: ``` ruby (..3).overlap?(nil..nil) # => Outputs `false` but should be `true` ``` I would like to attempt to fix this bug and will take a look at it this weekend. -- https://bugs.ruby-lang.org/

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:121359] [Ruby Feature#17016] Enumerable#accumulate
by midnight (Sarun R) 14 Mar '25

14 Mar '25

Issue #17016 has been updated by midnight (Sarun R). I have an issue that is kinda solvable with `scan` today and discover this old thread. Thank you all for putting thoughts into this. `enum_for` is really interesting, but it only works on `lazy` enumerable. Even though this issue is still pending, `each_with_object` seems available now. ~~~Ruby (1..10).each_with_object({ a: 0 }).map do |size, memo| memo[:a] += size end ~~~ This works on `lazy` too. From the observation, this was not the case back when the discussion started. ~~~Ruby (1..10).lazy.each_with_object({ a: 0 }).map do |size, memo| memo[:a] += size end ~~~ For anyone looking for something available today, `each_with_object` could be the solution. ---------------------------------------- Feature #17016: Enumerable#accumulate https://bugs.ruby-lang.org/issues/17016#change-112330 * Author: parker (Parker Finch) * Status: Open ---------------------------------------- ## Proposal UPDATE: Changed proposed method name from `#scan_left` to `#accumulate`. Add an `#accumulate` method to `Enumerable`. ## Background `#accumulate` is similar to `#inject`, but it accumulates the partial results that are computed. As a comparison: ``` [1, 2, 3].inject(0, &:+) => 6 [1, 2, 3].accumulate(0, &:+) => [0, 1, 3, 6] ``` Notably, the `accumulate` operation can be done lazily since it doesn't require processing the entire collection before computing a value. I recently described `#accumulate`, and its relationship to `#inject`, more thoroughly in [this blog post](https://medium.com/building-panorama-education/scan-left-a-lazy-incre…. ## Reasoning We heavily rely on the accumulate operation. We use an [event-sourcing](https://martinfowler.com/eaaDev/EventSourcing.html) pattern, which means that we are scanning over individual "events" and building up the corresponding state. We rely on the history of states and need to do this lazily (we stream events because they cannot fit in memory). Thus the scan operation is much more applicable than the inject operation. We suspect that there are many applications that could leverage the scan operation. [This question](https://stackoverflow.com/questions/1475808/cumulative-array-sum-… would be more easily answered by `#accumulate`. It is a natural fit for any application that needs to store the incrementally-computed values of an `#inject`, and a requirement for an application that needs to use `#inject` while maintaining laziness. ## Implementation There is a Ruby implementation of this functionality [here](https://github.com/panorama-ed/scan_left/) and an implementation in C [here](https://github.com/ruby/ruby/pull/3078). Update: @nobu has provided an alternative implementation [here](https://github.com/ruby/ruby/pull/1972). ## Counterarguments Introducing a new public method is committing to maintenance going forward and expands the size of the Ruby codebase -- it should not be done lightly. I think that providing the functionality here is worth the tradeoff, but I understand any hesitation to add yet more to Ruby! ---Files-------------------------------- scan_left_example.rb (2.93 KB) -- https://bugs.ruby-lang.org/

[ruby-core:121077] [Ruby master Misc#21143] Speficy order of execution const_added vs inherited
by fxn (Xavier Noria) 14 Mar '25

14 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/

Issue #20996 has been reported by cfis (Charlie Savage). ---------------------------------------- Bug #20996: Embed Failure https://bugs.ruby-lang.org/issues/20996 * Author: cfis (Charlie Savage) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Rice embeds Ruby in order to run its tests. This code has worked across multiple Ruby versions (current tests are 3.1, 3.2, 3.3 and 3.4 but previously tests were run on 3.0 and 2.x). However, it fails on 3.4 in different ways on different operating systems. The code is here - https://github.com/ruby-rice/rice/blob/master/test/embed_ruby.cpp#L10. ``` c int argc = 0; char* argv = nullptr; char** pArgv = &argv; // ruby_sysinit(&argc, &pArgv); ruby_init(); ruby_init_loadpath(); #if RUBY_API_VERSION_MAJOR == 3 && RUBY_API_VERSION_MINOR >= 1 // Force the prelude / builtins const char* opts[] = { "ruby", "-e;" }; ruby_options(2, (char**)opts); #endif ``` The test suite is here: https://github.com/ruby-rice/rice/actions/runs/12534403540/job/35007888873 With Ruby 3.4 on Fedora this fails with the following stack trace: ```c libruby.so.3.4!str_gsub(int
