That's useful info, thanks.

I guess the million dollar question is when is the next release likely
to be ready for production use? If it's unlikely this side of christmas
then I guess going back to 1.2 might be a better choice for me (with
your useful code snippet to get the functionality I want).

Cheers

Rakesh

In http://marc.theaimsgroup.com/?l=log4j-dev&m=112917692022155&w=2, M
 ark Womack provided a build for consideration to the log4j-dev list  
and the PMC as a candidate to be 1.3 alpha 7.  It isn't a release  
since there hasn't been a vote yet and the eventual 1.3 alpha 7 may  
be different (and may likely be due to bug 37122).  However, if you  
want to download the build and provide feedback, feel free.

One of the reasons that we are still calling 1.3 an alpha is the API  
is subject to change and an systematic review of all the API changes  
between 1.2 and 1.3 will be undertaken before freezing the API.  I'm  
not particularly fond of the particular way that formatting was  
integrated in 1.3 and believe that using an independent logging  
formatter class would result in equivalent performance and allow the  
user to choose his formatter.  The JDK provides other formatters  
other than MessageFormat and the current log4j 1.3 doesn't implement  
all of MessageFormat.

For example:

logger.debug("some data {}", value);

written using an external formatter would look like:

MessageFormatter.debug(logger, "some data {}", value);

The implementation of MessageFormatter would look something like:

public class MessageFormatter {
     private MessageFormatter() {}
     public static void debug(final Logger logger, final String fmt,  
final Object param1) {
         if (logger.isDebugEnabled()) {
            logger.debug(MessageFormat.format(fmt, new Object[]  
{ param1 }));
         }
     }
     //  repeated for other permutations
}

You could write a class for your own use now that would work with  
either log4j 1.3 or log4j 1.2.
