Bug ID: 61996 Summary: pywikibot.replaceExcept() may hang or cause an infinite loop Product: Pywikibot Version: compat (1.0) Hardware: All OS: All Status: NEW Severity: minor Priority: Unprioritized Component: General Assignee: Pywikipedia-bugs@lists.wikimedia.org Reporter: info@gno.de Web browser: --- Mobile Platform: ---
In some circumstances pywikibot.replaceExcept() may hang or have an infinite loop. Neigher keyboard interrupt nor any other event works anymore an the workstation must be restarted. Maybe this is caused by a malformed undetected regex. On the otherhand any interrupt should be possible to kill the task.
I found this on compat, maybe it is also the same problem in core.
