--- Comment #2 from Curt Arnold <[email protected]> 2010-03-19 03:59:14 UTC --- Bug 45721 introduced configurable ThrowableRenderer's and may be a more general solution to the issue instead of attempting to do it at layout time. The throwable in the ThrowableInformation is not serialized which comes into play if the converter was used on a logging event that had been deserialized by a receiver in Chainsaw. The SocketAppender and similar classes force a call to getThrowableStringRep() which results in the string representation being generated before the instance is serialized. When it deserialized, the ThrowableInformation has the string representation, but not the Throwable. >From looking at the code, it would seem that %throwable{compact} would in that case result in less output than %throwable{short} where normally it is the other way around. With the Chainsaw serialization issue, I'd like to avoid introducing anything into ThrowableInfoPatternConverter that depends on the presence of the throwable. Also, I'd like to avoid anything that attempts to parse a stack trace to find causes, etc. If you'd always like "compact" rendering in the current SVN HEAD, you can specify an alternative ThrowableRenderer either in configuration or programmatically. I think it is cleaner doing this at that phase, but it requires writing a ThrowableRenderer and not just configuration. If we had a CompactThrowableRenderer in either extras.jar or log4j.jar, then it would be back to just a configuration issue. If you'd like different renderings on different appenders, then we are back at adding some enhancement to %throwable{}, but I'd be more inclined to support %throwable{n} to do the first n lines or %throwable{regexp} to output only those lines that match a regular expression. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
