Logback Classic causes SecurityException ---------------------------------------- Key: LBCLASSIC-263 URL: http://jira.qos.ch/browse/LBCLASSIC-263 Project: logback-classic Issue Type: Bug Affects Versions: 0.9.28 Reporter: NC Assignee: Logback dev list PackagingDataCalculator invokes Class.getClassLoader(). This method throws a SecurityException when running under a security manager and that manager denies access to the ClassLoader. I'm submitting a PackagingDataCalculator patch which wraps the getClassLoader() invocation in a doPrivileged block. This allows these calls to succeed when the getClassLoader RuntimePermission is granted to logback-classic. -- 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-294) <if> requires Janino, which is considered harmful

<if> requires Janino, which is considered harmful ------------------------------------------------- Key: LBCLASSIC-294 URL: http://jira.qos.ch/browse/LBCLASSIC-294 Project: logback-classic Issue Type: Improvement Components: joran Affects Versions: 0.9.29 Environment: (Assuming 0.9.29 is the currently released version) Reporter: Joachim Durchholz Assignee: Logback dev list Priority: Blocker More on Janino below, here's the proposal: Have a variant of <if>, namely <if property="property name">. If the property does not exist or is false, use the <else> part, otherwise, use the <then> part. Problems with Janino: 1) Bloat. A footprint of 1 megabyte is amazingly small for an almost full Java compiler, but it still more than doubles the footprint for logging. 2) Reliability. If the logging configuration is user editable, they might add a Java expression that calls arbitrary internal APIs. I am aware that http://logback.qos.ch/manual/configuration.html#conditional claims that the generated code is sandboxed ("only context properties or system properties are accessible"). However, sandboxes require full security audits. Janino would require a security audit. I doubt that there are enough developer resources for this task available; the task could be reduced for Logback by keeping the available API narrow (just a bunch of properties is extremely tight), but I doubt that that is possible for Janino. Worse, those audits would need to be repeated for every new revision. 3) Security. Expressions that make it outside the sandbox could do any amount of nasty things. Intentionally or not (I can imagine scenarios for both). These problems do not exist for programmer-defined properties. Only PropertyDefiner descendants can be called from the configuration, and these are statically checkable in source. There is no need to worry about expressions that might try to call arbitrary internal APIs. (If I wanted to live with that kind of risk I'd be programming in Lisp, dammit!) -- 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-292) Support optional include files

Support optional include files ------------------------------ Key: LBCLASSIC-292 URL: http://jira.qos.ch/browse/LBCLASSIC-292 Project: logback-classic Issue Type: Improvement Components: joran Affects Versions: 0.9.26 Reporter: Joachim Durchholz Assignee: Logback dev list Priority: Minor Logback emits a warning if a file named in <include/> isn't present. Sometimes, an included configuration file is purely optional. E.g. I would want to mail a more verbose configuration to a customer who has some mysterious error where the standard logging simply isn't detailed enough. Unfortunately, this means that in the standard case, I'll be spammed with the missing file warning, plus heaps of INFO messages. This might distract from relevant logback configuration problems. Suggestion: extend <include/> so that it accepts <include optional="true" ... />. If an include is optional, it will not generate error messages if the requested configuration is not present. The loading code might want to differentiate between "does not exist" (to suppress the message) and other problems (which probably should still be reported). -- 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

scan/include interaction is not described ----------------------------------------- Key: LBCLASSIC-293 URL: http://jira.qos.ch/browse/LBCLASSIC-293 Project: logback-classic Issue Type: Improvement Components: joran Affects Versions: 0.9.29 Reporter: Joachim Durchholz Assignee: Logback dev list Priority: Trivial http://logback.qos.ch/manual/configuration.html does not tell whether it applies to included configuration files as well. (I understand it did not initially and has been doing since some specific revision.) I guess configuration.html should be changed to talk about configuration files in the plural form, and explain that there's an <include> directive near the top. -- 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-291) performance issue

performance issue ----------------- Key: LBCLASSIC-291 URL: http://jira.qos.ch/browse/LBCLASSIC-291 Project: logback-classic Issue Type: Improvement Components: Other Affects Versions: 0.9.29 Reporter: Roman Kosenko Assignee: Logback dev list http://logback.qos.ch/manual/encoders.html says: Below is an excerpt from the LayoutWrappingEncoder class illustrating how delegation to the wrapped layout instance is done. package ch.qos.logback.core.encoder; public class LayoutWrappingEncoder<E> extends EncoderBase<E> { protected Layout<E> layout; private Charset charset; public void doEncode(E event) throws IOException { String txt = layout.doLayout(event); outputStream.write(convertToBytes(txt)); outputStream.flush(); } private byte[] convertToBytes(String s) { if (charset == null) { return s.getBytes(); } else { return s.getBytes(charset); } } } Let's leave fact that this source is uncompilable... But in real source of ch.qos.logback.core.encoder.LayoutWrappingEncoder we can see another code. Method convertToBytes contains line: "return s.getBytes(charset.name());". So real variant isn't so fast as one in example - you get the name of your java.nio.charset.Charset and then String.getBytes make lookup by this name to get Charset instance again. And this is doing for every log message. P.S. I know, that String.getBytes(Charset) is available from Java 6 only. But it released in 2006 and current version is 7. If you want to support very old version of jre maybe is it better to separate versions like this is doing in other libraries? Another variant is direct using of CharsetEncoder. -- 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

performance issue ----------------- Key: LBCLASSIC-290 URL: http://jira.qos.ch/browse/LBCLASSIC-290 Project: logback-classic Issue Type: Improvement Components: Other Affects Versions: 0.9.29 Reporter: Roman Kosenko Assignee: Logback dev list In the ch.qos.logback.classic.Logger there is a comment related to filterAndLog_0_Or3Plus, filterAndLog_1, filterAndLog_2: /** * The next methods are not merged into one because of the time we gain by not * creating a new Object[] with the params. This reduces the cost of not * logging by about 20 nanoseconds. */ But if we use at least one "TurboFilter" then "new Object[]" is called twice in filterAndLog_1 & filterAndLog_2 (because of LoggerContext.getTurboFilterChainDecision_1 & LoggerContext.getTurboFilterChainDecision_2). So in this case you don't receive advantage of splitting, even more - merged version will be faster. And methods LoggerContext.getTurboFilterChainDecision_0_3OrMore, LoggerContext.getTurboFilterChainDecision_1, LoggerContext.getTurboFilterChainDecision_2 can be merged in one without any performance penalty. -- 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
