Hi,
Can you update me with the release date for log4j2 or at least a guidance
of when you are planning to release.

Re: Make LogEvent implementations Externalizable
Posted by Ralph Goers <ra...@dslextreme.com>.
I’d be afraid of breaking compatibility even now. However, I think what you really want to do is to create an ExternalizedLayout and then just use that instead of the default SerializedLayout. If you want to supply that Layout as a patch to a Jira issue it could be added at any time.

Make LogEvent implementations Externalizable
Posted by Scott Harrington <sc...@sns-usa.com>.
Ralph & co:
I hear you're gearing up for the release.
Last weekend I scratched an itch of mine relating to SocketAppender ->
SocketServer bandwidth, and was able to reduce a 500-character message
from around 1700 bytes to 700 bytes on the wire (it's easy to improve on
Java's default serialization).
I was going to submit an enhancement request with patch to JIRA but
instead I went on vacation for two weeks.
I made RingBufferLogEvent implement Externalizable, i.e. hand-coded
writeExternal / readExternal methods. I did NOT have time to make an
equivalent change to Log4jLogEvent, or to write up any performance tests
or regression tests.
Should I submit what I have for discussion and hopeful inclusion in 2.0?
Or will it have to wait for 2.1?
If we wait, then due to the necessary serialVersionUID change, v2.0
SocketAppender would not be able to talk to v2.1 SocketServer or vice
versa (unless ugly duplicate versions are maintained).
Below is what the added code looks like. I only tested in
RingBufferLogEvent but should be similarly usable in Log4jLogEvent, and
perhaps we should discuss a RingBufferLogEvent.readResolve that makes them
all become Log4jLogEvents on the SocketServer (receiving) end.

Nothing around here is cast in concrete. However, I personally have one more patch to apply and then I will propose doing the release. The release vote could come as soon as this weekend or it could be in a week or two.
