----------------------------------------
Summary: Improve logging for python virtualenv initialization
Key: MINIFICPP-2606
URL: https://issues.apache.org/jira/browse/MINIFICPP-2606
Project: Apache NiFi MiNiFi C++
Issue Type: Improvement
Reporter: Gábor Gyimesi
Assignee: Gábor Gyimesi
Python processor package dependencies are installed into a virtualenv using a
dependency installer script which is executed from the minifi process using a
system call. Unfortunately if the virtualenv initialization fails there is no
indication of the issue in the logs as the script output is only placed on the
stderr and stdout channels. Failure is only indicated like this:
{code:java}
[2025-04-22 12:43:49.150] [org::apache::nifi::minifi::core::extension::Module]
[error] Failed to initialize extension 'PythonExtension' in module
'minifi-python-script-extension'
[2025-04-22 12:43:49.150]
[org::apache::nifi::minifi::core::extension::ExtensionManager] [error] Failed
to initialize module 'minifi-python-script-extension' at
'/home/xavier/Downloads/nifi-minifi-llama-1.0.0/bin/../extensions/libminifi-pyt>
{code}
We should add additional logging by capturing the stdout and stderr of the
installer script and logging it to the minifi application logs for easier
debugging of the dependency install issues.
