New Revision: 941180
URL: http://svn.apache.org/viewvc?rev=941180&view=rev
Log:
added support for 'custom level definitions' in LogFilePatternReceiver, which allows the user to map
strings in the log file to Log4j levels
if there are extra spaces that would prevent a pattern from matching, strip them out
exclude empty lines (if appendNonMatches was false, would add an empty line to the log)
With these changes, redirection of Android logging via 'logcat -v time' will now render fine in Chainsaw, using:
<param name="logFormat" value="TIMESTAMP LEVEL/LOGGER(PROP(PID)):MESSAGE"/>
<param name="customLevelDefinitions" value="V=TRACE,D=DEBUG,I=INFO,W=WARN,E=ERROR,F=FATAL,S=OFF"/>
