bpo-38907: In http.server script, restore binding to IPv4 on Windows. by jaraco · Pull Request #17851 · python/cpython (original) (raw)
This PR takes a more surgical approach to GH-17378, addressing only the regression introduced with the dual-stack support added in 3.8 for the http.server command. Presumably, better support will be added to the HTTPServer and TCPServers for dual-stack support in bpo-25667 or bpo-20215, but this PR aims to minimally restore the prior expectation and not affect the behavior of those classes.
I considered writing tests for this change, but the existing tests for the http.server command mock out the intended behavior, so I've instead tested the change by applying the patch to Python 3.8.1 on Windows and confirmed it has the intended effect.
