When adding the QGIS feedback logger to the aligner, ther isn't a problem. When setting this to None this error occurs. To check if brdr handles this correctly when no QGIS-logger is provided.

[dieuska]

@roefem I have a question about this.
When using the aligner in QGIS, and we provide a QGIS-feedback-logger in the Aligner-initialisation, everything goes well.

I also made a advanced parameter in the UI to not include the feedback-logger. So None is provided on initialisation. this results in error in the printing module of QGIS, because logging cannot be written. You have an idea how to handle this in the most clean way? Or should we always provide a QGIS-feedback-logger? (I removed this because too much info was written down in the QGIS log so the feedback-logger could not follow writing and was slowing the processing)

zie:

brdrQ/autocorrectborders.py

Lines 684 to 691 in 5fd46d8

	if self.SHOW_LOG_INFO:
	log_info = feedback
	else:
	log_info = None
	aligner = Aligner(feedback=log_info,
	relevant_distance=self.RELEVANT_DISTANCE,
	threshold_overlap_percentage=self.THRESHOLD_OVERLAP_PERCENTAGE,
	)

[dieuska]

fix was needed in brdr. This fix will be available from version >=0.2.2

[dieuska]

we close this here as this is already fixed in brdr
