Revision: 5108
http://jython.svn.sourceforge.net/jython/?rev=5108&view=rev
Author: fwierzbicki
Date: 2008-08-08 18:24:44 +0000 (Fri, 08 Aug 2008)
Log Message:
-----------
Various fixes to improve Jython compatibility with CPython, especially when
passing PyCF_DONT_IMPLY_DEDENT. Added PyCF_DONT_IMPLY_DEDENT to codeop.py,
PyTableCode.java, and CompilerFlags.java to help test_codeop.py run. Began to
integrate tests from test_jy_compile.py, which appears to have started as a copy
of test_codeop.py, into test_codeop.py. Once test_jy_compile is fully
integrated into test_codeop.py I should be able to delete test_jy_compile. Also
added eval support to PythonPartial.g, since test_codeop exercises that
functionality.
