[jira] [Created] (LOG4J2-2360) Expose SourceLocation to public API

Jeff Shaw created LOG4J2-2360:
---------------------------------

             Summary: Expose SourceLocation to public API
                 Key: LOG4J2-2360
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2360
             Project: Log4j 2
          Issue Type: Improvement
            Reporter: Jeff Shaw


I learned there are three features of log4j2 and its official Scala API that could work together to improve performance with some API changes.

Log4j2's messages can include the source file name and line number.

Scala macros can be used to provide compile time file names and line numbers to runtime for zero cost. However, there is currently not a good way to combine the two.

I created the changes we'd need to allow clients of log4j2 to manually provide SourceLocation for a log message, and then I used the new methods to create SourceLocation for Scala files at compile time.

 

For log4j2 see [https://github.com/shawjef3/logging-log4j2/commit/4f75053cdfe39614fc60ecc609f3658cdd4840db] and for an example use by the scala loggers see [https://github.com/shawjef3/logging-log4j-scala/commit/dd9a5dd2d6bef80ef4f0334c2ed7043299ddbad4].
