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

[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

PatternLayout does not really respect ISO8601 for date time ----------------------------------------------------------- Key: LBCORE-137 URL: http://jira.qos.ch/browse/LBCORE-137 Project: logback-core Issue Type: Improvement Components: Layout Affects Versions: 0.9.19 Environment: irrelevant here Reporter: Brice Dutheil Assignee: Logback dev list Using the default "%d" "%date" or %d{ISO8601} does not output a correct ISO 8601 formatted date and time representation. Indeed there is a space between the date and the time, as the specification says having a space separator means there two fields : a 'date field' and a 'time field'. The specification consider this as acceptable for human reading though. However when processing logs it might cause some trouble to effectively parse the fields, especially when correlating logs from different applications. For now we have workarounds, but it seems reasonable to have a correct ISO8601 formatting. The correct ISO8601 representation for a 'date and time field' is to have the T indicator, for example '2007-03-01T13:00:00Z'. The workaround for now is to write ourself the correct ISO8601 pattern. Oh and by the way the timezone formatting options in the SimpleDateFormat are incomplete. The JodaTime format class org.joda.time.format.ISODateTimeFormat worth a look on this matter. Anyway date and time related classes in the JDK are not known for being the best at what they do. This problem is also found in log4j.

XML/HTML tags haven't get escaped in HTMLLayout ----------------------------------------------- Key: LBCLASSIC-180 URL: http://jira.qos.ch/browse/LBCLASSIC-180 Project: logback-classic Issue Type: Bug Components: layout Affects Versions: 0.9.18 Environment: Linux (Ubuntu), JavaSE 1.6 Reporter: Xu Hui Hui Assignee: Logback dev list View it here for a better looking: http://stackoverflow.com/questions/2069135/how-to-make-xml-get-escaped-in-h… I'm using logback (with slf4j) to do the logging, and I've got many XML content to be logged in both text files and HTML files (with HTMLLayout). However, logback just inserts the raw XML in the <TD> tags for the HTMLLayout, without any escaping or <pre> processing. Here is the snippet of my logback.xml: <appender name="ALL" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${DIR_ALL}/%d{yyyy-MM-dd}.%i.html</FileNamePattern> <TimeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <MaxFileSize>500KB</MaxFileSize> </TimeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <layout class="ch.qos.logback.classic.html.HTMLLayout"> <pattern>%d{HH:mm:ss.SSS}%logger{1}%msg</pattern> <cssBuilder class="ch.qos.logback.classic.html.UrlCssBuilder"> <url>${CSS_HREF}</url> </cssBuilder> <title>Logs (ALL)</title> </layout> And the following is what I got: <td class="Message">(DemoCall) parsing response failed. Details: <call><action>getmessage</action></call> </td> What I'm expecting: <td class="Message">(DemoCall) parsing response failed. Details: <call><action>getmessage</action></call> </td> Or better wrap the above message with a <pre> tag. Do I need to extend the HTMLLayout to archive that? Or is it my job to do a StringEscapeUtils.escapeHTML(msg) for each log statement (I'm not going to do that, since there also is a file appender for which the escaping is not needed).

Invalid multiple configuration file warning ------------------------------------------- Key: LBCLASSIC-159 URL: http://jira.qos.ch/browse/LBCLASSIC-159 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.917 Environment: Resin webapp Reporter: Hontvári József Assignee: Logback dev list I receive strange warnings in the status info. It says that logback.xml, which in this case comes from a file and not from the classpath, occurs multiple times. The file is specifies and logged using absolute path, so even relative paths cannot cause the warning. Logback configuration file is specified by the system property "logback.configurationFile". It is done by the Resin application server, somehow it is able to supply different properties for different web applications. I don't think this is important, however.

RollingFileAppender/TimeBasedRollingPolicy failing to ZIP files in different directory -------------------------------------------------------------------------------------- Key: LBCORE-169 URL: http://jira.qos.ch/browse/LBCORE-169 Project: logback-core Issue Type: Bug Components: Rolling Affects Versions: 0.9.24 Reporter: Tomasz Nurkiewicz Assignee: Logback dev list When using ZIP feature to compress old log files, Logback does not allow to put ZIP files in different directory like in this example: <file>logs\server.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>logs\arch\server.%d{yyyy-MM-dd_HHmm}.log.zip</fileNamePattern> </rollingPolicy> Running the attached test maven project (it takes 1 minute to run) will create server.log3560979839057.tmp (or similar) temporary file instead of ZIP file in /arch subdirectory (preferably this directory should be created if not exists). If fileNamePattern in rollingPolicy is changed to: "logs\server.%d{yyyy-MM-dd_HHmm}.log.zip" everything works as expected. The root of this issue is to be able to automatically ZIP files AND archive them in different directory. It would be great to be able to use date placeholders in folder names, for instance: <fileNamePattern>logs\arch-%d{yyyy-MM}\server.%d{yyyy-MM-dd_HHmm}.log.zip</fileNamePattern> so that Logback would automatically create folders for each month with ZIPped files. -- 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
