bug: intermittent ArgumentError from ignore_before_process on JRuby

[bf4]

I can't tell what causes this since it's internal code to rollbar which looks fine. Sharing in case this happens to anyone else.

• railties 6.1.7.5
• sidekiq 6.4.0
• rollbar 3.4.0

JRuby 9.4.1.0, ruby 3.1.0

Rails 7.0.6
Rollbar 3.4.0
jruby 9.4.3.0
ruby 3.1.4

We experienced the same thing. We can't create a minimal example to reproduce the issue but we got around it with this patch.

Rollbar::Notifier.class_eval do
  def use_exception_level_filters?(options)
    option_value = options && options[:use_exception_level_filters]

    return option_value unless option_value.nil?

    configuration.use_exception_level_filters_default
  end
end

The difference is options[:use_exception_level_filters] vs options.delete(:use_exception_level_filters)

https://github.com/rollbar/rollbar-gem/blob/master/lib/rollbar/notifier.rb#L409

---

These args are passed to Rollbar.log. At this point extra is a hash.

[1] pry(#<Rollbar::Notifier>)> extra
=> {:use_exception_level_filters=>true}
[2] pry(#<Rollbar::Notifier>)> extra.class
=> Hash

After use_exception_level_filters? is called extra returns a weird error.

[1] pry(#<Rollbar::Notifier>)> extra
ArgumentError: wrong number of arguments (given 0, expected 1)
from /usr/local/rvm/gems/default/gems/pry-0.14.2-java/lib/pry/ring.rb:43:in `<<'
Caused by RuntimeError: foo
from /workspaces/Profile/app/controllers/name_controller.rb:8:in `edit'
[2] pry(#<Rollbar::Notifier>)> extra.class
=> Hash

When ignore_before_process? is called it's with extra it produces this error.

[1] pry(#<Rollbar::Notifier>)> ignore_before_process?(level, exception, message, extra)
ArgumentError: wrong number of arguments (given 3, expected 4)
from /usr/local/rvm/gems/default/gems/rollbar-3.4.0/lib/rollbar/notifier.rb:158:in `ignore_before_process?'
Caused by RuntimeError: foobar
from /workspaces/Profile/app/controllers/name_controller.rb:8:in `edit'

When plugging in the actual value all is good.

[2] pry(#<Rollbar::Notifier>)> ignore_before_process?(level, exception, message, {:use_exception_level_filters=>true})
=> false

Side note: The method use_exception_level_filters? is a bit misleading as it also mutates the options.

While many consider avoiding mutation of method arguments preferable, this bug appears to be rooted in a Jruby issue. I've submitted Unexpected ArgumentError calling Forwardable delegated single splat method with keyword arguments
