| # 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. |
