Jay Kreps updated KAFKA-193:
----------------------------
Attachment: kafka-193-consistent-level-throwable.fix.v2.patch
Cool, here is the same patch updated against trunk to fix a few new breakages
due to new checkins. I also made two minor changes:
1. Changed LogHelper trait to Logging and made the file name match the trait
name. Motivation here is just to make the name trait-like...
2. Made Utils.registerMbean not throw an exception. Utils.swallow was depending
on log4j and this lead to a lot of unnecessary use of log4j directly. I think
it is better for jmx registration to not be a fatal exception (JMX shouldn't
kill the server or client, just log an error).
If no objections to these I am going to apply the updated patch.
> use by name parameter helper for logging and trait to include lazy logging
> and refactor code to use the new LogHelper

> 1) New tait to include logging and helper methods so if
> (log.isDebugEnabled()) is not required because it is in the helper and log
> paramaters are passed by name so not executed to tidy up the code
> 2) refactor all occurrence of logging to use the log helper
> 3/4 (possibly to be handled in to tickets) the "lint" affect from this for
> changes patched but not on trunk and new patches moving forward until this is
