[Feature-Request] Add special debugging option (write original Vcalendar body to file and write fixed Vcalendar body to other file)

[ifrh]

For debugging some strange behaviors, it would be nice,
if one could use a special debugging option from GUI or as Commandline parameter
to let DavMail write out to different files

• the original Vcalendar body
• the fixed Vcalendar body

It would be much easyier to analyse these single files, than copy the content out of the WIRE-logs,
since copying via editor could change copied content, too.

The code for creating that additional files should be called or implemented in

davmail/src/java/davmail/exchange/ExchangeSession.java

Lines 2165 to 2183 in 2b10b77

	protected void fixICS(byte[] icsContent, boolean fromServer) throws IOException {
	if (LOGGER.isDebugEnabled() && fromServer) {
	dumpIndex++;
	String icsBody = new String(icsContent, StandardCharsets.UTF_8);
	ICSCalendarValidator.ValidationResult vr = ICSCalendarValidator.validateWithDetails(icsBody);
	dumpICS(icsBody, true, false);
	LOGGER.debug("Vcalendar body ValidationResult: "+ vr.isValid() +" "+ vr.showReason());
	LOGGER.debug("Vcalendar body received from server:\n" + icsBody);
	}
	vCalendar = new VCalendar(icsContent, getEmail(), getVTimezone());
	vCalendar.fixVCalendar(fromServer);
	if (LOGGER.isDebugEnabled() && !fromServer) {
	String resultString = vCalendar.toString();
	ICSCalendarValidator.ValidationResult vr = ICSCalendarValidator.validateWithDetails(resultString);
	LOGGER.debug("Fixed Vcalendar body ValidationResult: "+ vr.isValid() +" "+ vr.showReason());
	LOGGER.debug("Fixed Vcalendar body to server:\n" + resultString);
	dumpICS(resultString, false, true);
	}
	}

Or is there an option for DavMail doing the wanted thing already?
Than some documentation need additional information.

Did you try to set davmail.dumpICS=10 for example ?
