bytearray.extend doesn't properly handle errors that arise during iteration of the argument:

Python 3.9.0a0 (heads/master:5150d32, Jun 26 2019, 10:55:32) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> array = bytearray()
>>> bad_iter = map(int, "X")
>>> array.extend(bad_iter)
ValueError: invalid literal for int() with base 10: 'X'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: <method 'extend' of 'bytearray' objects> returned a result with an error set

As far as I can tell, this bug is present on all versions of Python 3. This patch adds a fix and a regression test.

I'm having trouble backporting to 3.8. Reason: 'Error 110 while writing to socket. Connection timed out.'. Please retry by removing and re-adding the needs backport to 3.8 label.

Thanks @serhiy-storchaka!

Just a heads-up, it looks like the 3.8 backport timed out...
