But I still have the problem reflected in the stack trace with GDB:
the "value" being extracted is not of the Python type JavaError (it's
of the Python type "Throwable"), and doesn't have the method
"getJavaException", while the "exc" *is* of type JavaError. Either
the code in PyErr_SetJavaError() isn't correct, or the code in
throwPythonError() isn't correct.
Quite possibly so. If your contention is correct, then change line 565 in
functions.cpp to call 'getJavaException' on 'exc' instead of 'value'.
Actually, I misspoke. "exc" is of type "type" -- it's the "JavaError"
type object. I think the right fix is to not call "getJavaException"
at all; you've got the Throwable right there in your hand already.
Yes, that's what I'm currently thinking too. 'value' _is_ the throwable.
The code in functions.cpp could be significantly simpler, in that case.
I changed your sample code to raise a JavaError with a Java RuntimeException
as argument in getBooleanQuery() and stepping through throwPythonError()
shows that the code there is correct. 'value' is the JavaError exception
instance and calling 'getJavaException()' on it returns the
RuntimeException.
If there is a bug, it's elsewhere.
Andi..
from lucene import initVM, CLASSPATH, JavaError, RuntimeException

class MyQueryParser(PythonMultiFieldQueryParser):

raise JavaError, RuntimeException("foo")
p = MyQueryParser(['bletch', 'unbletch'], StandardAnalyzer())
print QueryParser.parse(p, "foo AND bar")
