From 35f5707b555d3bca92858de16760918e76463a1e Mon Sep 17 00:00:00 2001 From: Sebastian Pipping Date: Mon, 21 Feb 2022 15:48:32 +0100 Subject: [PATCH] 00378-support-expat-2-4-5.patch 00378 # Support expat 2.4.5 Curly brackets were never allowed in namespace URIs according to RFC 3986, and so-called namespace-validating XML parsers have the right to reject them a invalid URIs. libexpat >=2.4.5 has become strcter in that regard due to related security issues; with ET.XML instantiating a namespace-aware parser under the hood, this test has no future in CPython. References: - https://datatracker.ietf.org/doc/html/rfc3968 - https://www.w3.org/TR/xml-names/ Also, test_minidom.py: Support Expat >=2.4.5 Upstream: https://bugs.python.org/issue46811 Backported from Python 3.
