Bump Ruby 3.4.1

[guillaumewrobel]

warning: parser/current is loading parser/ruby34, which recognizes 3.4.0-compliant syntax, but you are running 3.4.1.

[iliabylich]

Yes, that's expected, see #1046.

[guillaumewrobel]

Thanks for the PR @iliabylich and kudos for the great work 🙏

[iliabylich]

#1057 has been reverted, I've merged it by accident. Like the linked issue above says I'm not backporting changed anymore (and I can always recommend you to switch to prism), so it's unclear if 3.4.x release of parser is going to ever happen.

[guillaumewrobel]

I see. Though, it's annoying that all Rubocop users will see the deprecation warning

warning: parser/current is loading parser/ruby34, which recognizes 3.4.0-compliant syntax, but you are running 3.4.1.

for each boot.

RuboCop only ever loads a specific parser version, that doesn't emit such a warning (parser/33 vs parser/current). Without knowing more specifics, I'd say one of your extensions is the cause.

For example, I fixed the same warning in rubocop-erb which used Parser::CurrentRuby directly to process erb code snippets instead of using ProcessedSource from RuboCop.

[iliabylich]

There should be a warning for 3.4.0 as well (because even 3.4.0 changes haven't been fully backported), but somehow when we branched out ruby34.y we didn't set version in parser/current.rb to 3.4.0-dev. I would say it's a bug that will cause some confusion but there's nothing critical. People would use 3.3 parser otherwise which is basically identical to current 3.4, they would only have a different warning message so again, not a big issue in terms of runtime behavior.

[Earlopain]

Yes, I agree it's ok the way it is now, considering the state of the project. Only some fringe syntax changes and nothing where I think the average user would notice. It's more along the lines of those known incompatibilities in the readme.

Basically no one will run 3.4.0 since 3.4.1 was released almost immediately after so that small mistake is even smaller because of that.

We are in ruby 3.4.1 and we are seeing the warnings too with parser (3.3.7.0)

.ruby-version

3.4.1

[artemave]

As above. In my case this is caused by i18n-tasks gem that is requiring parser/current. I reckon there will be a growing list of similar comments accumulating here.

[navidemad]

I had the warning due to i18n-tasks gem also, @artemave i made a PR to suppress the warning meanwhile:
glebm/i18n-tasks#613

[navidemad]

I am wondering if the easiest fix will be:

when /^3\.4\./
    current_version = '3.4.0'
    current_version = '3.4.1' <<<
    if RUBY_VERSION != current_version
      warn_syntax_deviation 'parser/ruby34', current_version
    end

Because between ruby 3.4.0 and 3.4.1 there was only few hours apart and it will avoid many warnings :)
