[ruby-core:115334] [Ruby master Feature#19998] Emit deprecation warnings when the old (non-Typed) Data_XXX API is used

Issue #19998 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19998: Emit deprecation warnings when the old (non-Typed) Data_XXX API is used https://bugs.ruby-lang.org/issues/19998 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- The replacement API was introduced in Ruby 1.9.2 (2010) [Feature #3064], and the old untyped data API was marked a deprecated in the documentation as of Ruby 2.3.0 (2015): https://github.com/ruby/ruby/commit/98544c372d948717de22afc86d162e411f1fb5f1 However, as of today, no deprecation warning of any sort is emitted when the API is used. Ultimately removing the old untyped API would allow to easily reclaim 8B on every `T_DATA` which could be used by the newly introduced embedded TypedData objects https://github.com/ruby/ruby/pull/7440 Was there any discussions about removing the old API at some point? Could we emit a warning when the API is used? Either verbose or non-verbose, to at least surface the issue to gem owners? This would help drive the effort to fix outdated gems, allowing to eventually remove this old API in the future. Looking at our big applications dependencies, there seem to be a small minority of gems still using the old API: - https://rubygems.org/gems/unf_ext - https://rubygems.org/gems/rotoscope - https://rubygems.org/gems/re2 - https://rubygems.org/gems/mysql2 Migrating them over doesn't seem too hard. -- https://bugs.ruby-lang.org/

[ruby-core:117027] [Ruby master Bug#20319] Singleton class is being frozen lazily in some cases

Issue #20319 has been reported by andrykonchin (Andrew Konchin). ---------------------------------------- Bug #20319: Singleton class is being frozen lazily in some cases https://bugs.ruby-lang.org/issues/20319 * Author: andrykonchin (Andrew Konchin) * Status: Open * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I've noticed suspicious behaviour (it doesn't affect anything in practice for me though) when an object becomes frozen only its own singleton class becomes frozen immediately. A singleton class of the immediate singleton class becomes frozen lazily after `#singleton_class` method call: ```ruby o = Object.new klass = o.singleton_class.singleton_class o.freeze puts klass.frozen? # false <== here we expect true puts o.singleton_class.singleton_class.frozen? # true puts klass.frozen? # true ``` I would expect all created singleton classes in an object singleton classes chain to become frozen immediately. -- https://bugs.ruby-lang.org/

[ruby-core:114038] [Ruby master Bug#19749] Confirm correct behaviour when attaching private method with `#define_method`

Issue #19749 has been reported by itarato (Peter Arato). ---------------------------------------- Bug #19749: Confirm correct behaviour when attaching private method with `#define_method` https://bugs.ruby-lang.org/issues/19749 * Author: itarato (Peter Arato) * Status: Open * Priority: Normal * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This issue is a special case of https://bugs.ruby-lang.org/issues/19745: Should dynamically added private methods via `.singleton_class.send(:define_method,...` be accessible publicly? See the following example? ```ruby private def bar; end foo = Object.new foo.singleton_class.send(:define_method, :bar, method(:bar)) foo.bar # No error. ``` The script above runs fine on latest Ruby 3.3. Is this correct to ignore the fact that the added method (method(:bar)) is private? This came up during a TruffleRuby investigation (https://github.com/oracle/truffleruby/issues/3134) where the result for the same script is: `private method 'bar' called for #<Object:0xc8> (NoMethodError)` -- https://bugs.ruby-lang.org/

[ruby-core:117990] [Ruby master Misc#20504] Interpolated string literal in regexp encoding handling
by kddnewton (Kevin Newton) 06 Jun '24

Issue #20504 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Misc #20504: Interpolated string literal in regexp encoding handling https://bugs.ruby-lang.org/issues/20504 * Author: kddnewton (Kevin Newton) * Status: Open ---------------------------------------- There is some very odd behavior that I'm not sure is intentional or not, so I'm looking for guidance. In here: ```ruby # encoding: us-ascii interp = "\x80" regexp = /#{interp}/ ``` the `regexp` variable is a ascii-8bit regular expression with the byte interpolated into the middle. However, if you inline that interpolation: ```ruby # encoding: us-ascii regexp = /#{"\x80"}/ ``` you get a syntax error, saying it's an invalid multi-byte character. I'm not sure what the rule is here, as it seems inconsistent. Is this the correct behavior? I would prefer if it would create an ascii-8bit regular expression like the first example, which would be consistent. -- https://bugs.ruby-lang.org/

[ruby-core:112538] [Ruby master Feature#19458] Expose HEREDOC identifier
by joelhawksley (Joel Hawksley) 04 Jun '24

Issue #19458 has been reported by joelhawksley (Joel Hawksley). ---------------------------------------- Feature #19458: Expose HEREDOC identifier https://bugs.ruby-lang.org/issues/19458 * Author: joelhawksley (Joel Hawksley) * Status: Open * Priority: Normal ---------------------------------------- I’d like to have access to the HEREDOC identifier. In the ViewComponent framework I help maintain, we added a method to declare a template as such: ```ruby class Component erb_template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` I'd prefer to be able to write: ```ruby class Component template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` And be able to see that the argument passed to `.template` was from a HEREDOC with an `ERB` identifier, which would allow me to use the correct template handler to compile the template. I could see this being implemented: 1) As a new property of String, such as `identifier` or `heredoc_identifier`. 2) By having HEREDOCs return a subclass of String that includes an `identifier` property. I'd be happy to work on implementing this change. -- https://bugs.ruby-lang.org/

Issue #20496 has been reported by gettalong (Thomas Leitner). ---------------------------------------- Bug #20496: Segfault when enabling YJIT https://bugs.ruby-lang.org/issues/20496 * Author: gettalong (Thomas Leitner) * Status: Open * ruby -v: ruby 3.4.0dev (2024-05-19T03:08:35Z master 7afc16aa48) [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I installed Ruby 3.4-dev via rbenv to see how the improvements in YJIT with 3.4-dev (after reading https://speakerdeck.com/k0kubun/rubykaigi-2024) translate to other parts of HexaPDF. However, when running the HexaPDF optimization benchmark with YJIT enabled, it regularly segfaults. This does not happen without YJIT. ## Steps to reproduce * Clone the HexaPDF repository: `git clone git@github.com:gettalong/hexapdf.git` * Download the file `a.pdf` attached to this issue into the `hexapdf` directory. * Change into the `hexapdf` directory and run `ruby --yjit -I lib bin/hexapdf -f optimize --compress-pages a.pdf out.pdf`. * The run may not fail every time but it does fail with a segfault many times. ## Segfault output ``` /tmp/hexapdf/lib/hexapdf/task/optimize.rb:289: [BUG] Segmentation fault at 0x00000000000000b0 ruby 3.4.0dev (2024-05-19T03:08:35Z master 7afc16aa48) +YJIT

Issue #20435 has been reported by mame (Yusuke Endoh). ---------------------------------------- Misc #20435: DevMeeting-2024-06-13 https://bugs.ruby-lang.org/issues/20435 * Author: mame (Yusuke Endoh) * Status: Open ---------------------------------------- # The next dev meeting **Date: 2024/06/13 13:00-17:00** (JST) Log: *TBD* - Dev meeting *IS NOT* a decision-making place. All decisions should be done at the bug tracker. - Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly. - Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue). - We will write a record of the discussion in the file or to each ticket in English. - All activities are best-effort (keep in mind that most of us are volunteer developers). - The date, time and place of the meeting are scheduled according to when/where we can reserve Matz's time. - *DO NOT* discuss then on this ticket, please. # Call for agenda items If you have a ticket that you want matz and committers to discuss, please post it into this ticket in the following format: ``` * [Ticket ref] Ticket title (your name) * Comment (A summary of the ticket, why you put this ticket here, what point should be discussed, etc.) ``` Example: ``` * [Feature #14609] `Kernel#p` without args shows the receiver (ko1) * I feel this feature is very useful and some people say :+1: so let discuss this feature. ``` - It is recommended to add a comment by 2024/06/10. We hold a preparatory meeting to create an agenda a few days before the dev-meeting. - The format is strict. We'll use [this script to automatically create an markdown-style agenda](https://gist.github.com/mame/b0390509ce1491b43610b9ebb665eb86). We may ignore a comment that does not follow the format. - Your comment is mandatory. We cannot read all discussion of the ticket in a limited time. We appreciate it if you could write a short summary and update from a previous discussion. -- https://bugs.ruby-lang.org/

[ruby-core:117288] [Ruby master Misc#20387] Meta-ticket for ASAN support
by kjtsanaktsidis (KJ Tsanaktsidis) 02 Jun '24

Issue #20387 has been reported by kjtsanaktsidis (KJ Tsanaktsidis). ---------------------------------------- Misc #20387: Meta-ticket for ASAN support https://bugs.ruby-lang.org/issues/20387 * Author: kjtsanaktsidis (KJ Tsanaktsidis) * Status: Open * Assignee: kjtsanaktsidis (KJ Tsanaktsidis) ---------------------------------------- I was asked to provide a bit of information about the current status of ASAN in CRuby, so I thought I'd open this meta-ticket to track all of the work I've been performing on fixing up address sanitizer support. So far, I have fixed the following issues related to ASAN support: * https://bugs.ruby-lang.org/issues/20001 + https://github.com/ruby/ruby/pull/9505, which dealt with two main themes: - Pushing the logic for capturing the start of the machine stack much closer to the top of the call stack, so that VALUEs stored close to the top of the machine stack get marked properly - Marking VALUEs stored on ASAN fake stacks during machine stack marking * https://bugs.ruby-lang.org/issues/20220 + https://github.com/ruby/ruby/pull/9734, which made M:N threading notify ASAN about stack switches in the same way that fibers do - Note: ASAN still doesn't work with M:N threading, but that actually has nothing to do with ASAN; it's because the most recent versions of Clang which are needed for ASAN just don't work with M:N threading either. See https://bugs.ruby-lang.org/issues/20243 for more info about that. * https://bugs.ruby-lang.org/issues/20273 + https://github.com/ruby/ruby/pull/10012, which disables `callcc` (and the associated tests) when ASAN is enabled - callcc is very rarely used in real code and the way it works is just fundamentally incompatible with ASAN (it performs longjmp's which I think are technically undefined behaviour) * https://bugs.ruby-lang.org/issues/20221 + https://github.com/ruby/ruby/pull/9865, which ignore some global symbols that ASAN defines from the global symbol leak checker * https://bugs.ruby-lang.org/issues/20274 + https://github.com/ruby/ruby/pull/10087, which ignores some false positive tests about memory leaks when ASAN is enabl * I updated the ASAN docs in https://github.com/ruby/ruby/pull/9922 to more closely reflect current reality The current state of things is that, by following the instructions in https://github.com/ruby/ruby/blob/master/doc/contributing/building_ruby.md, you can successfully build Ruby with ASAN enabled, however, the test suite has several failures. I'm currently working on addressing these: The next step is to merge https://github.com/ruby/ruby/pull/10122 (https://bugs.ruby-lang.org/issues/20310) which I plan to do next week (I'm currently away on a work trip). That makes sure that VALUEs stored in ASAN fake stacks from threads other than the currently running thread get marked during GC. After that, I need to push up patches for the remaining few issues. I mostly have these patches ready to go already; in fact, last week I got the full `make check` suite passing all tests with ASAN enabled! Once that's working, I'd like to investigate how ASAN can fit into CRuby's CI matrix somewhere so that it _stays_ working, although I have not thought too deeply about this yet. I will provide further updates on this ticket so anybody interested can stay in the loop. -- https://bugs.ruby-lang.org/

Issue #20459 has been reported by esad (Esad Hajdarevic). ---------------------------------------- Bug #20459: Ractor.select() deadlock? https://bugs.ruby-lang.org/issues/20459 * Author: esad (Esad Hajdarevic) * Status: Open * ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin20] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- When I run this script ``` echo = Ractor.new { Ractor.receive } Thread.new { puts Ractor.select(echo).inspect } sleep 0.1 echo.send "test" ``` the script never terminates. If I change thread body to ``` Thread.new { puts echo.take.inspect } ``` or introduce a small delay before #select like: ``` Thread.new { sleep 1; puts Ractor.select(echo).inspect } ``` then it works/terminates. -- https://bugs.ruby-lang.org/
