Subject: [PATCH] bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453)
|
|
|
|
|
|
(GH-31472)
|
|
|
|
|
|
|
|
|
|
|
|
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.
