New submission from Борис Верховский <boris.verk@gmail.com>: 1. go to https://docs.python.org/2/library/stringio.html (note the "/2/") 2. click on "You should upgrade and read the Python documentation for the current stable release." at the top I expect to be sent to the Python 3 documentation for StringIO (or at least the index.html page of the Python 3 documentaion) but because StringIO was moved from its own library into `io`, the Python 2 docs are linking to a 404 error page, because they just rewrite "/2/" to "/3/" in the URL. See attached PR for a list of all these broken pages and where they could redirect to. ---------- assignee: docs@python components: Documentation messages: 385821 nosy: boris, docs@python priority: normal pull_requests: 23179 severity: normal status: open title: Python 2.7 documentation links to 404 pages when the library was moved or renamed type: enhancement versions: Python 3.9 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue43044> _______________________________________
