Issue #19766 has been reported by mame (Yusuke Endoh). ---------------------------------------- Misc #19766: DevMeeting-2023-08-24 https://bugs.ruby-lang.org/issues/19766 * Author: mame (Yusuke Endoh) * Status: Open * Priority: Normal ---------------------------------------- # The next dev meeting **Date: 2023/08/24 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 2023/08/21. 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:114218] [Ruby master Bug#19770] TLS / Certificate Hostname Verification against IP fails with "address family must be specified"
by Schachi65 (Joachim Schachermayer) 17 Aug '23

Issue #19770 has been reported by Schachi65 (Joachim Schachermayer). ---------------------------------------- Bug #19770: TLS / Certificate Hostname Verification against IP fails with "address family must be specified" https://bugs.ruby-lang.org/issues/19770 * Author: Schachi65 (Joachim Schachermayer) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.4 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I dont't use Ruby directly but indirectly via Fluentd-1.16.1 (https://www.fluentd.org/) Fluentd uses Ruby 3.1.4. The problem is, that a TLS connection from a Fluentd Client to a Fluentd Server fails, if the connection is established using the IP address of the server and tls_verify_hostname is switched to on. In the servers certificate, in the SubjectAlternativeNames extention, there is the servers IP address set with the correct value. I get the error message " **address family must be specified** ". **Probable cause** : ext/openssl/lib/openssl/ **ssl.rb** line 288: Here the Methode IPAddr.new(hostname) is called with just one argument: return true if san.value == IPAddr.new( **hostname** ).hton lib/ **ipaddr.rb** line 594: Here the exception is raised with the observed error message: when Socket::AF_UNSPEC **raise** AddressFamilyError, " **address family must be specified** " The exception is raised, because the variable "family" has the value " **Socket::AF_UNSPEC** " because thats the default value of "family" if there is no additional parameter in the call to "initialize()". The documumentation of "initialize()" says in line 575/576/577: "Although the address family is determined automatically from a specified string, you can specify one explicitly by the optional second argument." But that automatic address determination is done too late. If no second parameter is given, it is not done at all because that exception is raised (assumption: the addr i always a string). **Probable solution** : If the address family is set to Socket::AF_UNSPEC with the call of "initialize()", dont't raise an exception now but do the in the comment announced automatic adress family detection here. -- https://bugs.ruby-lang.org/

[ruby-core:114323] [Ruby master Bug#19791] Debugger does not handle delete key correctly

Issue #19791 has been reported by stuartb (Stuart Bury). ---------------------------------------- Bug #19791: Debugger does not handle delete key correctly https://bugs.ruby-lang.org/issues/19791 * Author: stuartb (Stuart Bury) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux-musl] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- When entering the debugger using `binding.debugger` or the `rdbg` command, pressing the delete key on the keyboard to delete characters at the REPL merely prints "^[[3~" to the console, and does not actually delete anything. This is **very** inconvenient. Can this be fixed somehow? I really like the new debugger, but my swearing like a sailor every time I hit "delete" is starting to really annoy my wife... It is worth noting that if I run the `pry` command and then, within pry, call `binding.debugger`, the delete key operates correctly. I believe the issue is related in some way to readline support, or the lack thereof – but my Ruby installation was compiled with readline support. I've tried everything I can think of, and spent some time on Google trying to solve it, but the problem remains. It happens in Alpine 3.18 and also in Debian 12. -- https://bugs.ruby-lang.org/

Issue #19833 has been reported by ksss (Yuki Kurihara). ---------------------------------------- Bug #19833: Superclass of BasicObject is broken. https://bugs.ruby-lang.org/issues/19833 * Author: ksss (Yuki Kurihara) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-08-08T00:21:45Z master 69292676a2) [arm64-darwin22] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I encountered a phenomenon where a non-class object appeared in the superclass of BasicObject. The minimum reproduction code is below. ```rb module Mod end BasicObject.include Mod # or BasicObject.prepend Mod p BasicObject.superclass #=> 2431129 or false ``` I think it is a practical problem because I found it by running code that monitors `singleton_method_added` as follows. https://github.com/ksss/orthoses/blob/341019c78ba625bc5d36c0f359c7d88621990… -- https://bugs.ruby-lang.org/

Issue #19793 has been reported by sczimmer (Scott Zimmermann). ---------------------------------------- Bug #19793: Segmentation fault with large arrays https://bugs.ruby-lang.org/issues/19793 * Author: sczimmer (Scott Zimmermann) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [aarch64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I was doing ruby koans to learn ruby and I got a segmentation fault when it gets to the part where it uses `Symbol.all_symbols`. I realized it happens with any large Array, but I cannot reproduce in a small test script, just when it runs the whole ruby koans. So the minimal way to reproduce I have is: download rubykoans: https://github.com/edgecase/ruby_koans/blob/master/download/rubykoans.zip?r… ``` unzip rubykoans.zip cd koans # fix deprecated method call for ruby 3.2 ruby -i -pe 'sub "File.exists", "File.exist"' neo.rb ``` Edit about_asserts.rb, adding these two statements to make a big array to the first koan: ``` def test_assert_truth array = [] 99130.times { array << "a string"} assert false # This should be true end ``` run `ruby path_to_enlightenment.rb` and get a backtrace like the attached backtrace.txt I've tried this on two servers, ubuntu aarch64 and debian x86_64. On both it crashes with ruby 3.2.2 and works fine with ruby 3.1. On both I installed ruby built from source with RVM. On the server with more ram I had to increase the number more (above it's 99130) to get it to crash. ---Files-------------------------------- backtrace.txt (21.7 KB) -- https://bugs.ruby-lang.org/

[ruby-core:114381] [Ruby master Bug#19838] Ripper nested heredocs
by kddnewton (Kevin Newton) 12 Aug '23

12 Aug '23

Issue #19838 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Bug #19838: Ripper nested heredocs https://bugs.ruby-lang.org/issues/19838 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I'm seeing some odd behavior on nested heredocs in the ripper lexer. ``` ruby <<~H1 1 #{<<~H2} 2 H2 3 H1 ``` $ cat test.rb | ruby -rripper -e 'pp Ripper.lex(ARGF.read)' ``` ruby [[[1, 0], :on_heredoc_beg, "<<~H1", BEG], [[1, 5], :on_nl, "\n", BEG], [[2, 0], :on_ignored_sp, " ", BEG], [[2, 2], :on_tstring_content, "1\n", BEG], [[3, 0], :on_ignored_sp, " ", BEG], [[3, 2], :on_embexpr_beg, "\#{", BEG], [[3, 4], :on_heredoc_beg, "<<~H2", BEG], [[3, 9], :on_embexpr_end, "}", END], [[3, 10], :on_tstring_content, "\n", BEG], [[4, 0], :on_ignored_sp, " ", BEG], [[4, 4], :on_tstring_content, "2\n", BEG], [[5, 0], :on_heredoc_end, " H2\n", BEG], [[6, 0], :on_ignored_sp, " ", BEG], [[6, 2], :on_tstring_content, "3\n", BEG], [[7, 0], :on_heredoc_end, "H1\n", BEG]] ``` This seems totally correct. But if you change it to a non-indenting heredoc: ``` ruby <<-H1 1 #{<<~H2} 2 H2 3 H1 ``` $ cat test.rb | ruby -rripper -e 'pp Ripper.lex(ARGF.read)' ``` ruby [[[1, 0], :on_heredoc_beg, "<<-H1", BEG], [[1, 5], :on_nl, "\n", BEG], [[2, 0], :on_tstring_content, " 1\n" + " ", BEG], [[3, 2], :on_embexpr_beg, "\#{", BEG], [[3, 4], :on_heredoc_beg, "<<~H2", BEG], [[3, 9], :on_embexpr_end, "}", END], [[3, 10], :on_tstring_content, "\n" + " 3\n", BEG], [[4, 0], :on_ignored_sp, " ", BEG], [[4, 4], :on_tstring_content, "2\n", BEG], [[5, 0], :on_heredoc_end, " H2\n", BEG], [[7, 0], :on_heredoc_end, "H1\n", BEG]] ``` Now the newline on line 3 gets concatenated with the content from line 6, and that token is dropped from the list entirely. This seems unintentional, but I'm not sure. -- https://bugs.ruby-lang.org/
