----------------------------------------
Summary: Improve error handling in Python processors
Key: MINIFICPP-2387
URL: https://issues.apache.org/jira/browse/MINIFICPP-2387
Project: Apache NiFi MiNiFi C++
Issue Type: Improvement
Reporter: Gábor Gyimesi
Assignee: Gábor Gyimesi
Errors are handled multiple ways in the
* throwing PythonScriptException
* throwing PyException
* setting PyErr_SetString
The error handling should be revised. In case of the minifi_native python
module we should probably set the error with PyErr_SetString instead of
throwing exceptions that would result in throwing exception in python instead
of the c++ code. We should focus on having better error messages and tracebacks
in the logs in case of an error to be able to identify the source of the error.
We are also using PyErr_Fetch and PyErr_Restore functions that are deprecated
since Python 3.12 and should be replaced.
