This change does not log the file name and line numbers, but the function name. Together with the commit information that is logged in conjunction with a crash and that MaxScale can tell, when invoked, that is enough to be able to pinpoint the location where a logging was made. Furthermore, that is a lot less intrusive and less confusing for an end-user than filename + line. This is just a temporary workaround; the logging mechanism needs to get an overhaul: - Separate severity and logging target. - Take syslog severities into use. - Simplify what needs to be done by developer. - etc.
