How to emitt logs attached to the CalcJobNode while parsing?

[zhubonan]

When parsing output files of a calculation it can be useful to emit logs that include detailed exceptions traceback should they occur, and the Parser class does have a logger property. However, it seems that the logs are not stored in the database but only printed to the console (hence appear in the daemon logs). In contrast, the report method within a WorkChain does emit and log that is stored in the database.

Is it possible to make the Parser.logger do the same?

Yes this should be possible and I think this already happens. The Parser class creates a logger using the logger adapter

class Parser(ABC):
    """Base class for a Parser that can parse the outputs produced by a CalcJob process."""

    def __init__(self, node):
        """Construct the Parser instance.

        :param node: the `CalcJobNode` that contains the results of the executed `CalcJob` process.
        """
        from aiida.common.log import AIIDA_LOGGER
        from aiida.orm.utils.log import create_logger_adapter

        self._logger = create_logger_adapter(AIIDA_LOGGER.getChild('parser').getChild(self.__class__.__name__), node)

This create_logger_adapter should configure the logger such that any messages that get logged are also piped to the DBLogHandler. If it doesn't work for you, it would be good if you could open an issue with a MWE.

I see, thanks!
