From: Michael Felt Date: Wed, 26 Dec 2018 05:43:42 +0000 (+0100) Subject: bpo-34711: Return HTTPStatus.NOT_FOUND if path.endswith('/') and not a directory... X-Git-Tag: v3.8.0a1~196 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2062a20641febad5eb9c18d74e1cfb4d7a6e53ed;p=python bpo-34711: Return HTTPStatus.NOT_FOUND if path.endswith('/') and not a directory (GH-9687) AIX allows a trailing slash on local file system paths, which isn't what we want in http.server. Accordingly, check explicitly for this case in the server code, rather than relying on the OS raising an exception.
