Summary: Setting to disable extended stack trace for layouts
Key: LOG4J2-2750
URL: https://issues.apache.org/jira/browse/LOG4J2-2750
Project: Log4j 2
Issue Type: Improvement
Reporter: Mikhail Talisov
By default almost all layouts use an extended stack trace output format
(ExtendedStackTraceElement). Currently I can change the stack trace format in
PatternLayout by specifiyng its template (%throwable, %xThrowable, etc). When
specified %throwable then no class packaging information is included in output.
But when I use for example JsonLayout or AsyncAppender with any layout then no
way to exclude class packaging information from the stack trace (this mean
class loading from classpath for all stack trace elements). For performance
reason would be good to have a setting to disable extending the stack trace in
layouts.
It's possible to add new attribute "extendedStackTrace" (for example, which is
true by default) in layout elements (except PatternLayout and some other
layouts where no ThrowableProxyHelper#toExtendedStackTrace is using). When I
set extendedStackTrace="false" then stack trace must be serialized without
class loading for all stack trace elements. AsyncAppender must use refs
appender layout's attribute.
