Issue #6648 has been updated by Dan0042 (Daniel DeLorme). > IMO it shouldn't exist, redundant with `$0` Keep in mind that `$0` can be set as process name, so `Process.argv0` is not redundant (despite the unfortunate naming). > I like your proposed naming in https://bugs.ruby-lang.org/issues/6648#note-10 but I think we should add `RbConfig.ruby_args` before the rest and file a new ticket for the rest. Agreed. This will also allow me to make a clearer point for the security risk of re-executing `$0` when it is equal to "-e" ---------------------------------------- Feature #6648: Provide a standard API for retrieving all command-line flags passed to Ruby https://bugs.ruby-lang.org/issues/6648#change-108676 * Author: headius (Charles Nutter) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Currently there are no standard mechanisms to get the flags passed to the currently running Ruby implementation.

Inability to get the full set of command-line flags, including flags passed to the VM itself (and probably VM-specific) makes it impossible to launch subprocess Ruby instances with the same settings. A real world example of this is "((%bundle exec%))" when called with a command line that sets various flags, a la ((%jruby -Xsome.vm.setting --1.9 -S bundle exec%)). None of these flags can propagate to the subprocess, so odd behaviors result. The only option is to put the flags into an env var (((|JRUBY_OPTS|)) or ((|RUBYOPT|))) but this breaks the flow of calling a simple command line. JRuby provides mechanisms to get all its command line options, but they require calling Java APIs from Ruby's API set. Rubinius provides its own API for accessing comand-line options, but I do not know if it includes VM-level flags as well as standard Ruby flags. I know there is a (({RubyVM})) namespace in the 2.0 line. If that namespace is intended to be general-purpose for VM-level features, it would be a good host for this API. Something like... ``` class << RubyVM def vm_args; end # returns array of command line args *not* passed to the target script def script; end # returns the script being executed...though this overlaps with $0 def script_args; end # returns args passed to the script...though this overlaps with ARGV, but that is perhaps warranted since ARGV can be modified (i.e. you probably want the original args) end ``` -- https://bugs.ruby-lang.org/

It's mostly like `argv[0]` in C but it returns the Ruby script path being run (vs path of the current executable) and yet it's not `ARGV[0]`. So sort of related to this issue, but so awfully confusing I don't think we want to follow that unfortunate naming. I like your proposed naming in https://bugs.ruby-lang.org/issues/6648#note-10 but I think we should add `RbConfig.ruby_args` before the rest and file a new ticket for the rest.

[ruby-core:118172] [Ruby master Misc#20523] mswin and MSFT/vcpkg

Issue #20523 has been reported by MSP-Greg (Greg L). ---------------------------------------- Misc #20523: mswin and MSFT/vcpkg https://bugs.ruby-lang.org/issues/20523 * Author: MSP-Greg (Greg L) * Status: Open ---------------------------------------- Currently the `windows.yml`workflow caches MSFT/vcpkg packages and the `vcpkg.json` file locks the vcpkg repo to an older commit. This results in the following package versions being used: ``` Package Ruby CI Current vcpkg libffi 3.4.4#1 3.4.6 libyaml 0.2.5#4 0.2.5#4 openssl 3.1.1 3.3.0#1 readline 0#4 0#5 readline-win32 na 5.0#8 zlib 1.2.13 1.3.1 ``` Note the updated versions of libffi, openssl, and zlib. There seems to be a concern about using packages from vcpkg’s master branch (see [PR #10907](https://github.com/ruby/ruby/pull/10907)). Ruby-loco’s mswin build has been running for almost 5 years, and many of the extension gems that are part of the std-lib use vcpkg master branch packages in their CI. I don’t recall any significant issues with vcpkg. Depending on the OS, current dependency package versions are often not available. Ruby’s package dependencies are not part of the Windows OS, and MSYS2 and vcpkg normally upgrade packages when they’ve been verified to work with all packages that depend on them. Hence, Windows CI in Ruby master is an opportunity to check master against the most recent versions of its dependencies. I would like to propose that either: 1. vcpkg’s commit is updated more frequently to use current package 2. vcpkg master branch is used -- https://bugs.ruby-lang.org/

[ruby-core:112538] [Ruby master Feature#19458] Expose HEREDOC identifier
by joelhawksley (Joel Hawksley) 05 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/

If `Warning.warn` is redefined, then Ruby code may be invoked while YJIT is compiling, which is unsafe. ### Solution Performance warnings are best effort, so the simplest solution is to not emit warnings when YJIT is compiling.

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

[ruby-core:118174] [Ruby master Feature#6648] Provide a standard API for retrieving all command-line flags passed to Ruby
by Dan0042 (Daniel DeLorme) 04 Jun '24

04 Jun '24

Issue #6648 has been updated by Dan0042 (Daniel DeLorme). > I think it's everyone's understanding that `RbConfig.ruby` should always be the path of the currently-running ruby. Yes I believe that is everyone's understanding. At least it was mine. And it turns out to be incorrect. Sure in the vast majority of cases the static install path and the currently-running ruby are going to be the same thing, so one might say it's too small a detail to care about. But I happen to care about small details. > And I suspect it's also already the case on CRuby with `--enable-load-relative` (but it would be nice if someone can check, if it's not we should fix that). I tried, and `--enable-load-relative` doesn't appear to be a supported option in any version of ruby., > Given the existence of `RbConfig.ruby`, I think `RbConfig.ruby_args` is the best fit. I agree. > (BTW there is `Process.argv0` which is about (Ruby) `ARGV[0]` and not (C) `argv[0]` I'm afraid not; `Process.argv0` is about ruby `$0` which is very different from `ARGV[0]` ---------------------------------------- Feature #6648: Provide a standard API for retrieving all command-line flags passed to Ruby https://bugs.ruby-lang.org/issues/6648#change-108618 * Author: headius (Charles Nutter) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Currently there are no standard mechanisms to get the flags passed to the currently running Ruby implementation. The available mechanisms are not ideal: * Scanning globals and hoping they have not been tweaked to new settings * Using external wrappers to launch Ruby * ??? Inability to get the full set of command-line flags, including flags passed to the VM itself (and probably VM-specific) makes it impossible to launch subprocess Ruby instances with the same settings. A real world example of this is "((%bundle exec%))" when called with a command line that sets various flags, a la ((%jruby -Xsome.vm.setting --1.9 -S bundle exec%)). None of these flags can propagate to the subprocess, so odd behaviors result. The only option is to put the flags into an env var (((|JRUBY_OPTS|)) or ((|RUBYOPT|))) but this breaks the flow of calling a simple command line. JRuby provides mechanisms to get all its command line options, but they require calling Java APIs from Ruby's API set. Rubinius provides its own API for accessing comand-line options, but I do not know if it includes VM-level flags as well as standard Ruby flags. I know there is a (({RubyVM})) namespace in the 2.0 line. If that namespace is intended to be general-purpose for VM-level features, it would be a good host for this API. Something like... ``` class << RubyVM def vm_args; end # returns array of command line args *not* passed to the target script def script; end # returns the script being executed...though this overlaps with $0 def script_args; end # returns args passed to the script...though this overlaps with ARGV, but that is perhaps warranted since ARGV can be modified (i.e. you probably want the original args) end ``` -- https://bugs.ruby-lang.org/

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/
