[ http://jira.qos.ch/browse/LBCORE-164?page=com.atlassian.jira.plugin.system.i... ] Ceki Gulcu reassigned LBCORE-164: --------------------------------- Assignee: Ceki Gulcu (was: Logback dev list)
SizeAndTimeBasedFNATP will overwrite previous logging files with index > 9 on restart app. ------------------------------------------------------------------------------------------
Key: LBCORE-164 URL: http://jira.qos.ch/browse/LBCORE-164 Project: logback-core Issue Type: Bug Components: Rolling Affects Versions: 0.9.24 Environment: Windows XP, java jdk1.6.0_18 Reporter: Dieter Mueller Assignee: Ceki Gulcu
Configuration: <appender name="DebugLog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!--See also http://logback.qos.ch/manual/appenders.html#RollingFileAppender--> <file>c:/log/debug.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- rollover daily --> <fileNamePattern>c:/log/debug-old-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <maxHistory>3</maxHistory> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>10KB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <encoder> <pattern>%date{ISO8601} %-5level [%thread] %logger{30}:%line - %msg%n</pattern> </encoder> </appender> Steps to reproduce: 1. Start the application 2. debug.log was created. 3. let run, until periodscounter reaches 10 or more (or prepare the files), e.g. c:\log\debug-old-2010-08-10.0.log c:\log\debug-old-2010-08-10.1.log c:\log\debug-old-2010-08-10.10.log c:\log\debug-old-2010-08-10.11.log c:\log\debug-old-2010-08-10.12.log c:\log\debug-old-2010-08-10.2.log c:\log\debug-old-2010-08-10.3.log c:\log\debug-old-2010-08-10.4.log c:\log\debug-old-2010-08-10.5.log c:\log\debug-old-2010-08-10.6.log c:\log\debug-old-2010-08-10.7.log c:\log\debug-old-2010-08-10.8.log c:\log\debug-old-2010-08-10.9.log 4. restart the application 5. log to base.log 6. yyyy-MM-dd.10.log was (re-)created on rollover, overwrite the previous yyyy-MM-dd.10.log. Logging messages are lost. It looks like the root cause is the (reversed) sorting via filenames in method ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP.computeCurrentPeriodsHighestCounterValue(String) FileFilterUtil.reverseSortFileArrayByName(matchingFileArray); currentPeriodsCounter = FileFilterUtil.extractCounter(matchingFileArray[0], stemRegex); because the input file array looks like: c:\log\debug-old-2010-08-10.0.log c:\log\debug-old-2010-08-10.1.log c:\log\debug-old-2010-08-10.10.log c:\log\debug-old-2010-08-10.11.log c:\log\debug-old-2010-08-10.12.log c:\log\debug-old-2010-08-10.2.log c:\log\debug-old-2010-08-10.3.log c:\log\debug-old-2010-08-10.4.log c:\log\debug-old-2010-08-10.5.log c:\log\debug-old-2010-08-10.6.log c:\log\debug-old-2010-08-10.7.log c:\log\debug-old-2010-08-10.8.log c:\log\debug-old-2010-08-10.9.log and in reversed order: c:\log\debug-old-2010-08-10.9.log c:\log\debug-old-2010-08-10.8.log c:\log\debug-old-2010-08-10.7.log c:\log\debug-old-2010-08-10.6.log c:\log\debug-old-2010-08-10.5.log c:\log\debug-old-2010-08-10.4.log c:\log\debug-old-2010-08-10.3.log c:\log\debug-old-2010-08-10.2.log c:\log\debug-old-2010-08-10.12.log c:\log\debug-old-2010-08-10.11.log c:\log\debug-old-2010-08-10.10.log c:\log\debug-old-2010-08-10.1.log c:\log\debug-old-2010-08-10.0.log then the wrong index 9 of the first file is used! Suggestion for solution: Get all indizes and use the highest. for example: void computeCurrentPeriodsHighestCounterValue(final String stemRegex) { File file = new File(getCurrentPeriodsFileNameWithoutCompressionSuffix()); File parentDir = file.getParentFile(); File[] matchingFileArray = FileFilterUtil .filesInFolderMatchingStemRegex(parentDir, stemRegex); if (matchingFileArray == null || matchingFileArray.length == 0) { currentPeriodsCounter = 0; return; } // FileFilterUtil.reverseSortFileArrayByName(matchingFileArray); // currentPeriodsCounter = FileFilterUtil.extractCounter(matchingFileArray[0], stemRegex); for (File logFile : matchingFileArray) { int aPeriodCounter = FileFilterUtil.extractCounter(logFile, stemRegex); if (aPeriodCounter > currentPeriodsCounter) { currentPeriodsCounter = aPeriodCounter; } } if (tbrp.getParentsRawFileProperty() != null) { currentPeriodsCounter++; } }
