conversion word %ex length handling is off by one -------------------------------------------------
Key: LBCORE-179 URL: http://jira.qos.ch/browse/LBCORE-179 Project: logback-core Issue Type: Bug Components: Pattern Affects Versions: 0.9.26 Reporter: Michael Osipov Assignee: Logback dev list The %ex and %xEx define a stack trace length. The integer spec is somewhat faulty and misleading. First of all this is a stack trace depth imho and not length. Anyway, I was poking around with the SMTPAppender and wanted to include the sole exception message into the subject. The outcome was: 1. The docs do not define a valid interval for the integer value. You can only deduce from logic. 2. I defined %ex{short} and it included 2 lines of the stack trace. 3. I defined %ex{2} and it included 3 lines of the stack trace. 4. I defined %ex{0} and it included 1 line of the stack trace. 5. Defining any negative number omits the stack trace. But it does not make sense at all to have a negative stack trace depth. I checked also the source of the [https://github.com/ceki/logback/blob/master/logback-classic/src/main/java/ch/qos/logback/classic/pattern/ThrowableProxyConverter.java converter], the lines 54 and 58 cause the problem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira _______________________________________________ logback-dev mailing list logback-dev@qos.ch http://qos.ch/mailman/listinfo/logback-dev
