v1.79.0 introduced unsafe auto correct to Lint/UselessAssignment · Issue #14394 · rubocop/rubocop · GitHub

def testing
  attempts ||= 1

  do_something
rescue Exception1 => e
  raise e if attempts > 2

  # does something

  attempts += 1
  retry
rescue Exception2 => e
  raise e if attempts > 2

  # does something

  attempts += 1
  retry
end

Should not change this block of code at all

The cop makes the first instance of attempts += 1 into attempts + 1, which then splits into attempts\n1, which then gets removed entirely by Lint/Void.

Use above code sample in file.rb, and run rubocop -A file.rb

› bundle exec rubocop -V
