Please install either mwparserfromhell or wikitextparser. The Pywikibot ETP regex does not work for nested templates which is a known problem.

@Xqt what do you think of merging this bug to T55936? I forgot about them, will try to reproduce and give more information later

Was Pwb 3.0.dev0 (this version number did not change until this year for several years, although Pwb itself was regularly updated, probably it was a bug) → 6.0.1

Your traceback is surely Pywikibot 6.0.1 (stable). Anyway I can reproduce it:

Works for me with pymysql 0.10 ans Python 3.5 as follows:

>>> import pymysql
>>> from contextlib import closing
>>> connection = pymysql.connect(defer_connect=True)
>>> connection = closing(connection)
>>> with connection as conn, conn.cursor() as cursor:
	pass

@Vladis13: What was your previous environment (Python, Pywikibot, PyMySQL releases)?

I'm not sure having a never ending task is a good idea. You can create a ticket for specific clean ups (python2) or you can use gerrit hashtags if you want to have a way to find patch. You can also create a ticket for cleanups doable after a release maybe? (for example all deletions that can be done in v5 or v6) but a task that never gets resolved doesn't make much sense to me.

Now we have another but:

@Xqt: Hi, all related patches in Gerrit have been merged. Can this task be resolved (via Add Action... → Change Status in the dropdown menu), or is there more to do in this task? Asking as you are set as task assignee. Thanks in advance!

Done with https://gerrit.wikimedia.org/r/425981

Should be working again now (fix was only applied on 1/2 the hosts) please re-run l10nbot or +2 and it should work.

@Billinghurst: The source "File:The humanizing of commerce and industry; the Joseph Fisher lecture in commerce, delivered in Adelaide, 9th May, 1919 (IA humanizingofcomm00mussrich).pdf" does not exist. Take "File:The humanizing of commerce and industry, the Joseph Fisher lecture in commerce, delivered in Adelaide, 9th May, 1919.pdf" instead and input the new Name (without "File:") if ask for Enter a better name, or press enter to accept: . What is the result then?

I think @epytext is more readable and the conversion is done by our doc/conf.py, see rPWBC574a0218d7be. No need to change the system then except we find a better lint checker than darglint.
