Subject [jira] [Commented] (PYLUCENE-36) Python exception when handling a Java error
Date Tue, 27 Jun 2017 02:17:02 GMT


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:",

>                 Key: PYLUCENE-36
>                 URL:
>             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.
