# 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.
