New submission from Terry J. Reedy <[email protected]>:
On Travis, 'Documentation tests' passing is apparently required. Line 23 of
nntplib.rst is ">>> s = NNTP('news.gmane.org')" I use gmane and occasional
failures to respond are routine. Being able to merge should not depend on this
external site.
In addition to a real failure, the following happen on PR 14675 earlier today.
https://travis-ci.org/python/cpython/jobs/559289634
Warning, treated as error:
**********************************************************************
File "library/nntplib.rst", line ?, in default
Failed example:
s = NNTP('news.gmane.org')
Exception raised:
Traceback (most recent call last):

raise NNTPTemporaryError(resp)
nntplib.NNTPTemporaryError: 400 load at 16.59, try later
Try later is what I do. This exception should somehow be skipped. I don't
know anything about Travis and doctest tests and how flakey doctests are
supposed to be handled. If nothing else, put the whole example is a try-except
block?
>>> try: # News sites can fail to respond.
... s = NNTP('news.gmane.org')
... ...
... except: # If site failure, try later.
... pass
Since output varies, I presume output checking is suppressed.
