Timeout::Error doesn't let two-argument raise() set a new message
martind@pizzagate:~$ ruby -we 'require "timeout"; raise(Timeout::Error.new("hello"), "world")' Traceback (most recent call last): -e:1:in `<main>': hello (Timeout::Error) martind@pizzagate:~$
... say "world", like this:
martind@pizzagate:~$ ruby -we 'raise(RuntimeError.new("hello"), "world")' Traceback (most recent call last): -e:1:in `<main>': world (RuntimeError) martind@pizzagate:~$
... rather than "hello"?
Sorry to raise an issue against such an old version but, if I'm right about the cause being that Timeout::Error#exception ignores its arguments, then that, judging by https://github.com/ruby/ruby/blob/3d32c217586a48c709b762865a8abc46f9098455/lib/timeout.rb#L38, hasn't changed since.
I have a work around for what I'm trying to do, which is generic code to re-raise an exception with some added information, so I don't need a fix or help, but I wanted to do my little bit to help Ruby have fewer surprises. I was interested to discover, in doing this, the new :cause option. I did try to check that I'm not raising a duplicate, but sorry if I failed.
