Erster Stand der Hintergrundprozesse, die auf der Synology unter /volume1/homes/wagner/SolarManager laufen: der Manager selbst, die Sammler je Geraet, die MQTT-Bruecke, der Wecker und - neu hinzugezogen - der AutoAction-Runner, der als Hintergrundprozess hierher gehoert und nicht ins Web-Verzeichnis. Zugangsdaten stehen nicht mehr im Quelltext, sondern in config.ini, die nicht mit eingecheckt wird. Vorlage ist config.ini.example, gelesen wird sie von konfig.py. Betroffen waren solarManager.py (Datenbank und Wattpilot), zeit.py, gatherWaterData.py, wecker.py und skoda_testdaten.py, das sich das Passwort bisher aus dem Quelltext eines anderen Moduls herausgesucht hat. Die Kia-Anbindung ist mit dem Fahrzeug entfallen: kiaTest.py, gatherCarData.py und hyundai_kia_connect_api sind nicht mehr dabei, ebenso gatherInverterData.py, auf das nur noch eine auskommentierte Zeile zeigte. Die mitgelieferten Bibliotheken bleiben im Repository - die NAS hat kein pip, sie muessen neben den Skripten liegen. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Global Error Handler
|
|
|
|
This module provides a global error handler and an interface that allows
|
|
error handlers to be registered with the global error handler via entry points.
|
|
A default error handler is also provided.
|
|
|
|
To use this feature, users can create an error handler that is registered
|
|
using the ``opentelemetry_error_handler`` entry point. A class is to be
|
|
registered in this entry point, this class must inherit from the
|
|
``opentelemetry.sdk.error_handler.ErrorHandler`` class and implement the
|
|
corresponding ``handle`` method. This method will receive the exception object
|
|
that is to be handled. The error handler class should also inherit from the
|
|
exception classes it wants to handle. For example, this would be an error
|
|
handler that handles ``ZeroDivisionError``:
|
|
|
|
.. code:: python
|
|
|
|
from opentelemetry.sdk.error_handler import ErrorHandler
|
|
from logging import getLogger
|
|
|
|
logger = getLogger(__name__)
|
|
|
|
|
|
class ErrorHandler0(ErrorHandler, ZeroDivisionError):
|
|
|
|
def _handle(self, error: Exception, *args, **kwargs):
|
|
|
|
logger.exception("ErrorHandler0 handling a ZeroDivisionError")
|
|
|
|
To use the global error handler, just instantiate it as a context manager where
|
|
you want exceptions to be handled:
|
|
|
|
|
|
.. code:: python
|
|
|
|
from opentelemetry.sdk.error_handler import GlobalErrorHandler
|
|
|
|
with GlobalErrorHandler():
|
|
1 / 0
|
|
|
|
If the class of the exception raised in the scope of the ``GlobalErrorHandler``
|
|
object is not parent of any registered error handler, then the default error
|
|
handler will handle the exception. This default error handler will only log the
|
|
exception to standard logging, the exception won't be raised any further.
