I'm unable to create a bugzilla account at http://bugzilla.slf4j.org/createaccount.cgi Could someone enter this bug report for me? If I change my version of logback to 0.9.11 I don't get this. I get it when I use logback version 0.9.13. I'm using version 1.5.5 of slf4j.

Messages from multiple senders interleaved on one line
by Michael Olson 02 Oct '09

02 Oct '09

Hello all, I'm new to logback, and I'm trying out a configuration that is, more or less, a word-for-word transcription of an example configuration from the documentation; you can view the configuration here: http://logback.pastebin.com/m1a6f2875 I'm having problems where I'm getting interleaved messages on a single line. I don't believe this is expected behavior, and it certainly makes it harder to understand what's going on. I've tried searching the mailing list and bug list to no avail. Here's an example from one log file: 2009-09-30 15:45:31,649 [Thread-5] INFO CalaisSubmitter - CalaisFeedSubmitter clean shutdown 2009-09-30 15:45:33,2302009-09-30 15:45:33,230 [ [Thread-15] INFO PostItemSubmitter - Shutdown aborted queue operation Thread-19] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:33,231 [2009-09-30 15:45:33,231Thread-17] [ INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:33,231 [2009-09-30 15:45:33,231Thread-17] [Thread-21] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:34,230 [main] INFO Eventweb - All stopped and here's an example from another log file: 2009-09-30 15:47:10,061 [Thread-5] INFO CalaisSubmitter - CalaisFeedSubmitter clean shutdown 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15]Thread-21]Thread-17] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15]Thread-21] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,378 [Thread-19] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:12,378 [main] INFO Eventweb - All stopped Can anyone tell me why I'm getting interleaved messages, and what I might be able to do to prevent this from happening? Thanks, - Michael

Hi, how is possible to log ONLY the log message for one specified java package ? For example I have to log only the log call from com.test.mypack.* classes. Do I have to write a filter ? Thanks a lot for all help

reference to an evaluator
by Hontvári József 29 Sep '09

29 Sep '09

Is there a way to refer to a previously defined evaluator in EvaluatorFilter instead of specifying it inline? I would like to use the same evaluator in two filters in two appenders. As I remember this is possible, but now I cannot find where it is mentioned in the manual.

ThrowableProxy and instanceof in EventEvaluator
by Hontvári József 28 Sep '09

28 Sep '09

In an event evaluator called in an option of an "ex" formatting specifier I would use a "throwable instanceof example" expression. This is the same as in Example 5.3 in the documentation, which also uses instanceof. This doesn't work because the throwable object is not a Throwable but a ThrowableProxy. Again, at another place, in the table at the beginning of the "Evaluator Filters taking Java Expressions" section in chapter Filters it is shown that the type of throwable is Throwable (annd not ThrowableProxy). Somehow I still get a ThrowableProxy instead of Throwable.

Split long data on multiple rows
by Anders Hammar 22 Sep '09

22 Sep '09

Hi, I have a framework that utilizes logback-core for logging. Due to limitations in the software reading the log files, a new requirement is that long data should be split on multiple rows. I'm trying to figure out if there a simple way of doing this? More info: What I have is an extension of the PatternLayoutBase which adds the converters for my event class. I'm using the standard RollingFileAppender. So, let's say I have a FooConverter, which gets the foo info from the event. But, when logging to the file, the foo info part must never be longer than x chars. If it is, it should be split on multiple rows. Other data (generated by other converters) should then be repeated. Any suggestions on how to do this in a clean logback way is appreciated! What I'm currently thinking is to loop on the converters (calling PatternLayoutBase.writeLoopOnConverters multiple times), but I need to know when that's required... Anyone done something similar? /Anders

Dual licensing logback
by Ceki Gulcu 18 Sep '09

18 Sep '09

Hello all, After a very long investigation resulting in a better understanding of licensing issues, I think dual-licensing logback under EPL 1.0 and LGPL 2.1 would help with the project's adoption. Licensees can then choose either the terms of the EPL or the terms of the LGPL when they use logback. The EPL license will placate organizations which refuse the restrictions imposed by the LGPL whereas the LGPL license ensures continuity in licensing and also keeps the door open for licensees already bound by the terms of (L)GPL. Comments? ps. If you intend to respond, please do so on logback-users@. -- Ceki Gülcü Logback: The reliable, generic, fast and flexible logging framework for Java. http://logback.qos.ch

Urgent Technical Issue
by Ayman Hammoudeh 16 Sep '09

16 Sep '09

Hello, I have a problem with TimeBasedRollingPolicy and that is older files are not deleted when I set the MaxHistory property let's say for example '2' it should delete files that are older than two days right??? But it doesn't delete any files!!!??? So my question is why files older that 2 days from the current date are not deleted. Here is my XML file: <configuration> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>RollTimeTest.%d.log</FileNamePattern>  <MaxHistory>2</MaxHistory> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{HH:mm:ss.SSS}[%thread] %-5level %logger{35} - %msg%n</Pattern> </layout> </appender> <root level="debug"> <appender-ref ref="FILE" /> </root> </configuration> Any help would be appreciated. Regards, Ayman Hammoudeh

Time Based Rollover in 0.9.17
by Stephen Duncan Jr 16 Sep '09

16 Sep '09

I've noticed that some of my applications using logback have stopped doing their time-based rollover. This change coincides with my upgrade of those apps from 0.9.16 to 0.9.17. These are apps that do not run continously - they are kicked off via cron a couple times a day. Those processes that do run continuously (such as the webserver) do still rollover correctly. Anyone else seen this change in behaviour? Is there any change in configuration needed for 0.9.17? Or is it a bug? -- Stephen Duncan Jr www.stephenduncanjr.com
