A warning appears every time a gem with native extensions is loaded by bundler during local development

[uvlad7]

Describe the problem as clearly as you can

bin/console (or any bundle exec / require "bundler/setup" stuff) prints Ignoring tzfrb-0.1.0 because its extensions are not built. Try: gem pristine tzfrb --version 0.1.0 warnings when tzfrb is a local gem with native extensions

Did you try upgrading rubygems & bundler?

Yes

Post steps to reproduce the problem

Create a gem

 bundle gem tzfrb --ext=rust 
 cd tzfrb
 bundle install
 bundle exec rake compile

• How your ruby is setup (OS package, from source, using a version manager).
  Installed via mise

vladimir@np940x5n:~/tzfrb (master)$ bundler -v
Bundler version 2.6.9
vladimir@np940x5n:~/tzfrb (master)$ ruby -v
ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [x86_64-linux]

Which command did you run?

bin/console

What were you expecting to happen?

Pry session without warnings on top
I was able to suppress this with

module AnnoyingGemWarningSilencer
    def contains_requirable_file?(file)
        return super unless source.is_a?(Bundler::Source::Gemspec)
        return false if ignored?

        super
    end
end

Gem::BasicSpecification.prepend(AnnoyingGemWarningSilencer)

on top of my bin/console

What happened instead?

Ignoring tzfrb-0.1.0 because its extensions are not built. Try: gem pristine tzfrb --version 0.1.0
Ignoring tzfrb-0.1.0 because its extensions are not built. Try: gem pristine tzfrb --version 0.1.0
Ignoring tzfrb-0.1.0 because its extensions are not built. Try: gem pristine tzfrb --version 0.1.0
Ignoring tzfrb-0.1.0 because its extensions are not built. Try: gem pristine tzfrb --version 0.1.0
# extension is built
3.3.0 :001 > Tzfrb.hello('Ruby')
 => "Hello from Rust, Ruby!"

I found this is due to irb using Gem.try_activate here.

You're not supposed to use Gem.try_activate in a bundler/setup context, so I started a discussion upstream to see if it can be removed or scoped to non-bundler usages.

I also created #8766 on our side, similar to your proposed patch, to workaround things on our side.
