[DRE-maint] Bug#840664: ruby-faker: FTBFS randomly (failing tests)

[Santiago Vila]

I said:

Something like this:

#!/usr/bin/ruby
require 'faker'
while true do
  email = Faker::Internet.email
  if not email.match(/.+@[^.].+\.\w+/)
    printf("%s\n", email)
  end
end

[ Sorry if that's not good style, I don't know ruby at all ].

Unfortunately, I have been running this for a while without any result.

A better strategy would be probably to analyze the code and try to
prove that it "must" work (in Knuth style). Since we do know that
it does not always work, we should fail at proving that, and discover
what's wrong while trying.

Stupid question: Should this really be [^.].+\. or maybe [^.]+\. ?

Thanks.
