THREESCALE-11906: Upgrade to Ruby 3.3 #4129

mayorova · 2025-08-08T08:47:18Z

What this PR does / why we need it:

Because Ruby 3.1 is EOL

Which issue(s) this PR fixes

https://issues.redhat.com/browse/THREESCALE-11906

Verification steps

Special notes for your reviewer:

There was a previous failed attempt to upgrade here: #3864

akostadinov

Maybe we need to update io-console to 0.7.1 to keep it with the default in ruby and avoid native compilation errors on fedora 42.

https://stdgems.org/io-console/

But it's alright to merge as is and try.

I doesn't work for me, bundle exec rails assets:clobber assets:precompile fails with this error:

$ bundle exec rails assets:clobber
bin/rails aborted!
ArgumentError: wrong number of arguments (given 3, expected 1..2) (ArgumentError)

(See full trace by running task with --trace)

What I did:

Updated my .tool-versions to point to ruby 3.3
Installed bundler 2.5.22

jlledom · 2025-08-11T12:05:34Z

.tool-versions.sample

-ruby 3.1.5
+ruby 3.3.1
 nodejs 18.20.4
 python 2.7.18


I know it's not related, but, why do we need python?

I believe this was needed for macs, not sure why...
Maybe @josemigallas or @lvillen can confirm whether this is still needed.

It's required by some dependency. A while ago python 3 was made the default in macOS and broke such dependency, so porta could not run.

I doubt anything modern will need python 2.7.18, maybe you need to try again with 3.

Agree on upgrading io-console. Either here or in another PR

Yes, there is some other thing needed. And also, this PR is currently blocked by #4130, which is WIP, so this one is also WIP 🙃

jlledom · 2025-09-24T15:28:05Z

@mayorova #4130 is merged, is this reviewable now?

mayorova · 2025-09-25T07:22:01Z

@mayorova #4130 is merged, is this reviewable now?

Nope, it actually depends on #4145

This branch will need to be rebased.

lib/developer_portal/config/initializers/liquid_expression_literals_patch.rb

+# This module adds a 'present' literal to the liquid expressions, so that
+# expressions such as the following can be used:
+#    {% if current_account.applications.first == present %}
+# This is required because existing templates use it
+# Previously, this feature was added like this:
+#    Liquid::Expression::LITERALS['present'] = :present?
+# but in the latest Liquid this constant hash is frozen


I trust you, but is this feature tested in the test suite?

jlledom

It all works for me 👍

Unfortunately, this is causing issues in midstream builds.

This version requires Rust

This can be fixed easily by installing the rust-toolset package.

This doesn't work because build environment is hermetic.

Even if the build fails due to the rust issue, I think it's fine to merge this. We'll have to fix midstream to support rust. I think it's fine to depend on rust stuff, native components will require rust more frequently I think, since it's gradually replacing C. So if we don't do it for prometheus, we'll end up doing it anyway for some other gem.

And you know, we really don't want to make the Rust cult angry, in fact, we should completely rewrite porta and apisonator in Rust, as a goodwill gesture to them.

probably we need to somehow point hermeto at the Cargo.toml but we only have it later, when the gem is downloaded :(

maybe we need to add the matching prometheus-client-mmap sources as build sources and then point at their Cargo for additional deps fetch.

we should completely rewrite porta and apisonator in Rust, as a goodwill gesture to them

As a first step lets quickly migrate to https://artichoke.github.io/artichoke/artichoke/, I think we will be safe if our interpreter was written in a proper language.

An amazing piece of engineering, now, do you think the Rust cult would spare my life I write a rust compiler in Ruby?

Almost free of memory leaks, of course

spare my life I write a rust compiler in Ruby?

If that ruby compiler run on top artichoke, perhaps. Just make sure not to build a rust interpreter in ruby and run it with the Ruby's YJIT rust implementation because the thing may become conscious and destroy us all.

since it's gradually replacing C. So if we don't do it for prometheus, we'll end up doing it anyway for some other gem.

I'm not sure if it will happen in the foreseeable future of the project.

We can't merge this until we figure out how to build rust-dependant projects. Otherwise, all future builds will be blocked forever 😞

src/lib.rs

I understand this is only a PoC but it can live in a special sub-dir in the worst case (like script/yarn). In the best case it will only live inside the midstream repo.

Not sure about midstream, it's required to run cargo fetch to populate the Cargo.lock from Cargo.toml.
But yeah, once (if) we make it work, we can make the required adjustments.
