Add new TriggeringPolicy class to cause one rollover at the start of each run ----------------------------------------------------------------------------- Key: LBCORE-91 URL: http://jira.qos.ch/browse/LBCORE-91 Project: logback-core Issue Type: New Feature Components: Appender Affects Versions: 0.9.15 Environment: - Reporter: Rick Beton Assignee: Logback dev list Priority: Minor A new TriggeringPolicy will cause the logfile to rollover once at startup when used with FixedWindowRollingPolicy. This is useful during development so that the logfiles of recent runs are still available. Here is a candidate implementation. Note that * <append>true</append> is required - otherwise the previous file is overwritten before rollover happens, so rollover results in a useless list of empty files. * the documentation would need to warn users of the effect of running multiple applications concurrently (i.e. concurrent operating system processes) with the same logfiles. This applies even without the suggested feature. package ch.qos.logback.core.rolling; import java.io.File; import ch.qos.logback.core.rolling.TriggeringPolicyBase; /** * SimpleStartupTriggeringPolicy triggers a rollover once at startup only. This * is useful for preserving older logfiles during development. * * @author Rick Beton */ public final class SimpleStartupTriggeringPolicy<E> extends TriggeringPolicyBase<E> { private boolean fired = false; public SimpleStartupTriggeringPolicy () { // does nothing } public boolean isTriggeringEvent( final File activeFile, final E event ) { final boolean result = !fired && (activeFile.length() > 0); fired = true; if (result) { addInfo( "Triggering rollover for " + activeFile ); } return result; } } -- 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-61) TimeBasedRollingPolicy can not be used with any other triggering policies

TimeBasedRollingPolicy can not be used with any other triggering policies ------------------------------------------------------------------------- Key: LBCORE-61 URL: http://jira.qos.ch/browse/LBCORE-61 Project: logback-core Issue Type: Bug Reporter: Szel Zoltan Assignee: Logback dev list Priority: Critical If someone would like to have a time based rolling policy with a size based triggering policy, than the user will get a NullPointerException,: at ch.qos.logback.core.rolling.helper.Compress.GZCompress(Compress.java:130) at ch.qos.logback.core.rolling.TimeBasedRollingPolicy.rollover(TimeBasedRollingPolicy.java:142) at ch.qos.logback.core.rolling.RollingFileAppender.rollover(RollingFileAppender.java:91) at ch.qos.logback.core.rolling.RollingFileAppender.subAppend(RollingFileAppender.java:116) at ch.qos.logback.core.WriterAppender.append(WriterAppender.java:124) at ch.qos.logback.core.AppenderBase.doAppend(AppenderBase.java:81) at ch.qos.logback.core.spi.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:51) at ch.qos.logback.classic.Logger.appendLoopOnAppenders(Logger.java:282) at ch.qos.logback.classic.Logger.callAppenders(Logger.java:266) at ch.qos.logback.classic.Logger.buildLoggingEventAndAppend(Logger.java:487) at ch.qos.logback.classic.Logger.filterAndLog(Logger.java:479) The cause of this issue is the isTriggeringEvent method in the TimeBasedRollingPolicy which has a side effect, namely it prepares the file name of the file which is about to rotate. If someone uses a triggering policy other than the same TimeBasedRollingPolicy, than the isTriggeringEvent method will not be called, hence the elapsedPeriodFileName will be null, hence a null pointer exception will be thrown in the start of the compression or while renaming. Please modify the isTriggeringEvent to not have this side effect + the rollover logic to capture the time information from the current event.

Question about a custom binary file appender.
by Joern Huxhorn 02 Aug '09

02 Aug '09

Hi Ceki. I'd like to implement a file appender that writes the binary Lilith format, i.e. gzipped protobuf-serialized events, instead of Strings. I'd also like to have the same functionality that's supported by RollingFileAppender right now. Unfortunately, there seems to be no way to simply write bytes instead of a String. How would you go from here? Reimplementing everything from the start seems to be a pretty bad idea. What do you think about enhancing the RFA so it's using byte[] instead of Strings? The current behavior could be implemented using those methods + string.getBytes("UTF-8") or CharsetEncoder... Any idea, suggestions? Regards, Joern.

add a context listener that automatically configures JMX -------------------------------------------------------- Key: LBCLASSIC-114 URL: http://jira.qos.ch/browse/LBCLASSIC-114 Project: logback-classic Issue Type: New Feature Components: Other Reporter: Philippe Marschall Assignee: Logback dev list Priority: Minor Setting up logback JMX for a web application requires a bit too many manual steps. It is not enough to simply add <jmxConfigurator /> to the configuration file. You should also set the context path but often you can't know that in advance. In addition you still need to write custom code to [prevent memory leaks|http://logback.qos.ch/manual/jmxConfig.html#leak]. These issues could all be addressed by a custom context listener. <listener> <listener-class>ch.qos.logback.classic.selector.servlet.JmxEnabler</listener-class> </listener> Code attached. -- 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

Logger allows TRACE messages when reset to DEBUG ------------------------------------------------ Key: LBCLASSIC-109 URL: http://jira.qos.ch/browse/LBCLASSIC-109 Project: logback-classic Issue Type: Bug Environment: SLF4J 1.5.6 and Logback 0.9.15 Reporter: Andrew Ruch Assignee: Logback dev list Priority: Minor When reconfiguring the LoggerContext, TRACE messages are logged even when the Logger level is set to DEBUG. As Ceki pointed out, the following test reproduces the issue. @Test public void levelResetTest() { LoggerContext loggerContext = new LoggerContext(); Logger root = loggerContext.getLogger(LoggerContext.ROOT_NAME); root.setLevel(Level.TRACE); assertTrue(root.isTraceEnabled()); loggerContext.reset(); //Logger is reset to DEBUG assertFalse(root.isTraceEnabled()); <-- assertion fails assertTrue(root.isDebugEnabled()); } -- 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-94) Rollover at launch time

Rollover at launch time ----------------------- Key: LBCORE-94 URL: http://jira.qos.ch/browse/LBCORE-94 Project: logback-core Issue Type: Bug Components: Rolling Affects Versions: 0.9.15 Reporter: Ceki Gulcu Assignee: Ceki Gulcu Rollover does not occur for old files when short lived application is restarted. This issue is related to LBCORE-26.However, the solution implemented in LBCORE-26 works if the RollingFileAppender has the File property set. This is not always the case. For instance <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>test.%d.log.zip</FileNamePattern> </rollingPolicy> <layout/> </appender> <root level="info"> <appender-ref ref="FILE"/> </root> Problem originally reported by Ch Pasha.

[JIRA] Created: (LBCORE-60) Allow rolling based on time or file size

Allow rolling based on time or file size ---------------------------------------- Key: LBCORE-60 URL: http://jira.qos.ch/browse/LBCORE-60 Project: logback-core Issue Type: New Feature Components: Appender Affects Versions: 0.9.9 Reporter: Szel Zoltan Assignee: Logback dev list The rolling grouping file appender allows to roll over on a specific interval(TimeBasedRollingPolicy) or when the log file has reached a specific file size. But unfortunately Logback does not support both to use together. For example if i want to roll over every day but i also want to roll the file when it is greater than 100MB. Please consider adding this feature to Logback and feel free to contact me if further clarification is required.
