Bug #17033: Infinite Traceback when encountering an Exception while catching an Exception
https://bugs.ruby-lang.org/issues/17033#change-86577
* Author: NickHackman (Nick Hackman)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]
* Backport: 2.5: DONTNEED, 2.6: REQUIRED, 2.7: REQUIRED
----------------------------------------
In Ruby 2.7.1 when an Exception occurs and another occurs when handling the first one it results in an infinite Traceback that doesn't mention the error.
```ruby
class MyException < StandardError
def initialize(obj)
@obj = obj
end
def to_s
@obj.to_strm
end
end
begin
raise MyException.new('test'), 'message'
rescue StandardError => e
puts e.to_s
end
```
In the above instance, there's a typo `to_strm` doesn't exist for type String, but instead of a normal case of a typo saying that the method doesn't exist the output is
```
~ λ ruby ruby_traceback_hell.rb
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
Traceback (most recent call last):
...
```
it keeps going without printing any sort of message about the actual error.
It's expected that this would result in a message saying that the method is undefined, and this is the behavior on 2.5.1, and appears to be a regression in 2.7.1
