Aborting post-run: invalid raw log file string error when log file is empty

[simonhaenisch]

I've set LOG_FILE_LEVEL=error because we don't need the log files but there seems to be no way to turn them off entirely with Renovate CE.

However now every repo prints a warning log after finishing:

Aborting post-run: invalid raw log file string

I assume it happens because the log file is actually empty when no error log has occurred.

Would prefer an option to disable log files but just wanted to report what seems to be a bug anyway.

This is because Renovate CE/EE parses the logs after each run to extract various metadata, for example for determining repository statuses. This makes Renovate CE/EE more efficient by placing repositories into the appropriate scheduling bucket. Thats just one example, and I suggest not disabling file logs if possible, as they are needed for normal operation.

You can use the logging configuration options to control log retention.

I suppose we could make the log cleanup support even more aggressive if needed tho.

Thanks for raising this!.

Hey thanks for the details, and yeah actually now I switched the log files to contain more detailed logs (debug) because I need to avoid the normal logs going into our log drain containing credentials, so I set that log level to info.

I've set the log retention to 1 day already, so i think this might work for us for now.
