41667, 41668 - initial switch to xmlcore 47044 - mention of xmlcore in What's New 50687 - mention of xmlcore in the library reference re-apply xmlcore changes to xml: 41674 - line ending changes (re-applied manually), directory props 41677 - add cElementTree wrapper 41678 - PSF licensing for etree 41812 - whitespace normalization 42724 - fix svn:eol-style settings 43681, 43682 - remove Python version-compatibility cruft from minidom 46773 - fix encoding of \r\n\t in attr values in saxutils 47269 - added XMLParser alias for cElementTree compatibility additional tests were added in Lib/test/test_sax.py that failed with the xmlcore changes; these relate to SF bugs #1511497, #1513611

# During the development of Python 2.5, an attempt to move the "xml"
|
|
# package implementation to a new package ("xmlcore") proved painful.
|
|
# The goal of this change was to allow applications to be able to
|
|
# obtain and rely on behavior in the standard library implementation
|
|
# of the XML support without needing to be concerned about the
|
|
# availability of the PyXML implementation.
|
|
#
|
|
# While the existing import hackery in Lib/xml/__init__.py can cause
|
|
# PyXML's _xmlpus package to supplant the "xml" package, that only
|
|
# works because either implementation uses the "xml" package name for
|
|
# imports.
|
|
#
|
|
# The move resulted in a number of problems related to the fact that
|
|
# the import machinery's "package context" is based on the name that's
|
|
# being imported rather than the __name__ of the actual package
|
|
# containment; it wasn't possible for the "xml" package to be replaced
|
|
# by a simple module that indirected imports to the "xmlcore" package.
|
|
#
|
|
# The following two tests exercised bugs that were introduced in that
|
|
# attempt. Keeping these tests around will help detect problems with
|
|
# other attempts to provide reliable access to the standard library's
|
|
# implementation of the XML support.
