GEOSGeometry error logging when handling a GEOSException

[Richard Boon]

When instantiating an invalid GEOSGeometry and catching the GEOSException, the logger still logs a GEOSException. I would expect no error logging when catching and handling the exception.
For example:

from django.contrib.gis.geos import GEOSGeometry, GEOSException
import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

try:
    GEOSGeometry("POLYGON ((20 30, 35 35, 30 20))")
except GEOSException:
    pass

This will display the following error message:

2020-12-09 10:03 ERROR GEOS_ERROR: IllegalArgumentException: Points of LinearRing do not form a closed linestring

It seems that the logging happens here: ​https://github.com/django/django/blob/2c5d6dc44779448de1497f32c925c96975fae461/django/contrib/gis/geos/libgeos.py#L99

These errors are logged before exceptions are caught. It's not feasible to recognize in Django that they're handled in you app. You can try to add your own filter to the logger.
