Summary: Python exception when handling a Java error
Key: PYLUCENE-36
URL: https://issues.apache.org/jira/browse/PYLUCENE-36
Project: PyLucene
Issue Type: Bug
Environment: Python 3.5, Ubuntu 16.04, Java 8
Reporter: Paulo Villegas
Attachments: pylucene-6.5.0-py3.5.patch

When handling a Java exception via the {{JavaError}} class, Python 3.5 generates an exception due to the call to {{unicode}} (which does not exist in Python 3), hence masking the actual Java exception with a Python _NameError_ exception.

I guess this is a consequence of PYLUCENE-35. That one fixed the problem with Unicode characters in Java exceptions for Python 2, but it shouldn't be applied to Python 3 (since in Python 3 the {{str}} type *is* natively Unicode).

The attached small patch (applied only to the Python 3 branch) fixes it for me.

Patrick J. McNerthney commented on PYLUCENE-36:
-----------------------------------------------

A nit-pick on the Python 3 purity of the generated code. The u prefix on string constants is only supported to make it easy for the same code to run in both Python 2 and 3. Since this is generating Python 3 specific code, the changed line should remove the u"..." string constants, resulting in:

{{
line(out, 2, 'return "\\n".join((str(super(JavaError, self)), " Java stacktrace:", str(writer)))')
}}
