B �A�[W?�@sXdZddlZe�d�jZe�d�jZe�d�Ze�d�Ze�d�Z[Gdd �d e �Z dS) aShared support for scanning document type declarations in HTML and XHTML. Backported for python-future from Python 3.3. Reason: ParserBase is an old-style class in the Python 2.7 source of markupbase.py, which I suspect might be the cause of sporadic unit-test failures on travis-ci.org with test_htmlparser.py. The test failures look like this: ====================================================================== ERROR: test_attr_entity_replacement (future.tests.test_htmlparser.AttributesStrictTestCase) ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/travis/build/edschofield/python-future/future/tests/test_htmlparser.py", line 661, in test_attr_entity_replacement [("starttag", "a", [("b", "&><"'")])]) File "/home/travis/build/edschofield/python-future/future/tests/test_htmlparser.py", line 93, in _run_check collector = self.get_collector() File "/home/travis/build/edschofield/python-future/future/tests/test_htmlparser.py", line 617, in get_collector return EventCollector(strict=True) File "/home/travis/build/edschofield/python-future/future/tests/test_htmlparser.py", line 27, in __init__ html.parser.HTMLParser.__init__(self, *args, **kw) File "/home/travis/build/edschofield/python-future/future/backports/html/parser.py", line 135, in __init__ self.reset() File "/home/travis/build/edschofield/python-future/future/backports/html/parser.py", line 143, in reset _markupbase.ParserBase.reset(self) TypeError: unbound method reset() must be called with ParserBase instance as first argument (got EventCollector instance instead) This module is used as a foundation for the html.parser module.
