Move LogbackPlugin code to git ------------------------------ Key: CONSPLUG-20 URL: http://jira.qos.ch/browse/CONSPLUG-20 Project: Console Plugin Issue Type: Task Reporter: Rüdiger Assignee: Logback dev list The code for the LogbackPlugin is not in the general GIT repository. It seems to live in subversion only. The comment "Unfortunately, the console plugin is somewhat outdated. It expects logback version 0.9.9. It will be upgraded in the coming weeks." shows some age by now... maybe someone wants to help out. -- 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

[JIRA] Created: (LBCLASSIC-212) Logback classic doesn't work with Tomcat

Logback classic doesn't work with Tomcat ---------------------------------------- Key: LBCLASSIC-212 URL: http://jira.qos.ch/browse/LBCLASSIC-212 Project: logback-classic Issue Type: Bug Affects Versions: 0.9.21 Reporter: Grzegorz Borkowski Assignee: Logback dev list Priority: Critical We have a web application running on Tomcat 6.0.26, which uses SLF4J for logging. Until now, we used SLF4J-Simple, and it worked very well. Now we try to switch to Logback, but we are not able to make it work. It works for logging one-line messages. But whenever any exception is thrown on server, which should print a stack trace, server hangs (It doesn't matter whether we actually print the stack trace in log or not). From what I was able to observe, it looks like it falls into endless loop, throwing "ClassNotFoundException: ch.qos.logback.classic.spi.ThrowableProxyUtil", which is caught and tried to be logged, which throws this exception again, and so on. I don't know why it throws this ClassNotFoundException - perhaps classloader issue? But even copying the logback jars to Tomcat's lib directory, I'm not able to run the application: than it has problems with starting up. Sometimes it freezes during loading web app, and often it helps to attach and detach debugger to Tomcat - it's a kind of magic... Anyway, it's horrendously painful, and I'm not able to make it work. Why such common setup (webapp on Tomcat) is not described in Logback documentation??? This is our configuration file : <configuration scan="true"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">  <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n%ex</pattern> </encoder> </appender> <root level="info"> <appender-ref ref="STDOUT" /> </root> </configuration> (changing scan to "false" doesn't help. Also changing pattern to the one not containing "%ex" doesn't help) This is part of pom file related to logging: <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.0</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>0.9.21</version> <scope>runtime</scope> </dependency>  <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> <scope>provided</scope> </dependency>  <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>1.6.0</version> </dependency> If we change dependency from logback to SLF4J simple (1.6.0) than everything works smoothly, stacktraces are printed to console, no freezing, everything is perfect. -- 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

Implement AsyncAppender ----------------------- Key: LBCLASSIC-242 URL: http://jira.qos.ch/browse/LBCLASSIC-242 Project: logback-classic Issue Type: New Feature Components: appender Reporter: Andrew Kowal Assignee: Logback dev list Logback still lacks AsynAppender like the one in Log4j. This feature is *critical* for production use in heavy loaded applications. This is the show stopper for us to migrate from Log4j to Logback. Some time ago there was similar issue LBCLASSIC-20, but it was closed after implementing async compression. So this one is just about asynchronous appender decorator. -- 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

[JIRA] Created: (LBCLASSIC-52) Allow multiple addresses for "to" property of SMTPAppender

Allow multiple addresses for "to" property of SMTPAppender ---------------------------------------------------------- Key: LBCLASSIC-52 URL: http://jira.qos.ch/browse/LBCLASSIC-52 Project: logback-classic Issue Type: Improvement Reporter: Andrey Utkin Assignee: Ceki Gulcu SMTPAppender don`t allow to specify multiple addresses in single "to" property. So that, it is (almost?) impossible to specify multiple "to" addresses via variable substitution. We should know exact number of addresses (variables) to specify appropriate quantity of <to> elements. But number of "to" addresses could be changed during application using and differ from customer to customer. So, IMFO it will be helpful to allow specifying multiple addresses in one <to> element. Multiple addresses could be separated by comma, for example (as comma is not valid character for email address). Right now we are using simple workaround. We subclass SMTPAppender and overwrite addTo(): {code} @Override public void addTo(String to) { StringTokenizer st = new StringTokenizer(to, ","); while(st.hasMoreTokens()) { super.addTo(st.nextToken().trim()); } } {code} This solution works just fine for us. May be it will be good to include this feature in core logback too. -- 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

[JIRA] Created: (LBCORE-242) log rollover should be configurable using %d multiple times in file name pattern

log rollover should be configurable using %d multiple times in file name pattern -------------------------------------------------------------------------------- Key: LBCORE-242 URL: http://jira.qos.ch/browse/LBCORE-242 Project: logback-core Issue Type: Improvement Components: Rolling Affects Versions: 1.0.0 Reporter: Thomas Corte Assignee: Logback dev list Trying to configure a log rollover with logs being *rolled daily* and put into a directory named "yyyy-MM", i.e. one folder for each *month* containing that month's logs, I'm using the following appender config: {noformat} <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>app.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <fileNamePattern%d{yyyy-MM}/app.%d{yyyy-MM-dd}.log</fileNamePattern> </rollingPolicy> <encoder> <pattern>%d{"yyyy-MM-dd HH:mm:ss,SSS"} [%thread] %-5level %logger{36} - %msg%n%xEx</pattern> </encoder> </appender> {noformat} However, it seems as if the current logback implementation merely considers the first %d specification, which leads to a log rotation only once per month instead of the desired once per day frequency. I figure this is because via %d, the log rotation frequency and the file name pattern are somewhat tied together and seemingly can't be specified independently. It would be nice if either multiple %d specifiers would be supported, with an option to specify which one should be considered for the rollover period. Even better, it might be a good idea to support the rollover period to be specified separately and independently from the file name pattern; arguably, using the file name patterns for both is somewhat convenient, but violates the principle of "separation of concerns". -- 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

[JIRA] Created: (LBCLASSIC-272) Automatic MDC inheritance with thread pools cases false data printed in the log

Automatic MDC inheritance with thread pools cases false data printed in the log ------------------------------------------------------------------------------- Key: LBCLASSIC-272 URL: http://jira.qos.ch/browse/LBCLASSIC-272 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.9.27 Environment: Applies to all Logback versions, specifically tested with Logback 0.9.27. Reporter: Lóránt Pintér Assignee: Logback dev list MDC inheritance when used in conjunction with a thread pool can turn out to be malicious. Consider the following in a web server where each line in the log contains the current user's name. 1. A web request comes in and processing is started on a thread 2. Authenticate the user (on original thread) 3. Put the user name into the MDC (on original thread) 4. Create some Runnable and pass it to a thread pool to be run in the background (on thread pool thread) Let's take a look at the logs that are printed from the Runnable created in step 4. Without automatic MDC inheritance (e.g. when using Log4J) these log lines will contain no user name. This can be good or bad, depending on what you want. If you do want the user name in these log lines, you can explicitly transfer the MDC from the originating thread to the thread pool thread. If you don't want to print the user name for background tasks, you are already done. If you have no access to the thread pool or the Runnables, you simply get no MDC information. However, if you do have automatic MDC inheritance (as with Logback), the log lines *will* contain a user name, but not from the originating thread. The thread pool thread will instead inherit its MDC from the first thread that executed a Runnable on it. This can never be what you want. You can correct this by transferring the original MDC manually, or clearing it explicitly inside your Runnable. But if you forget to do this, or you don't have access to the thread pool and the Runnables, you will end up with corrupt data in your logs. The latter can happen if you are using some third-party API that maintains its own thread pool. I can see two ways to fix this issue: 1) Make automatic MDC inhertance configurable from logback.xml. This is not a perfect solution: if you mix code that relies on MDC inheritance with code that relies on no MDC inheritance you will have no good value for this setting. 2) Remove the automatic MDC inheritance feature altogether. Instead, Logback (or even better: SLF4J) could provide some utility classes to wrap Runnable's and Callable's in something like this: {code} class MdcRetainingRunnable implements Runnable { private final Map context; public MdcRetainingRunnable { this.context = MDC.getCopyOfContextMap(); } @Override public void run() { Map originalContext = MDC.getCopyOfContextMap(); MDC.setContextMap(context); try { runWithMdc(); } finally { MDC.setContextMap(originalContext); } } abstract protected runWithMdc(); } {code} I would prefer solution #2 as it provides for the rule of least astonishment. -- 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
