http://bugzilla.slf4j.org/show_bug.cgi?id=201 Summary: Need ability to shutdown loggers and flush appenders Product: SLF4J Version: 1.6.x Platform: PC OS/Version: Windows NT Status: NEW Severity: enhancement Priority: P1 Component: Core API AssignedTo: slf4j-dev(a)qos.ch ReportedBy: mike.schall(a)gmail.com There needs to be a way to shutdown logging and flush async appenders so when a process is closing, all log events are written before the process is closed. Should ILoggerFactory have a shutdown or stop method? It could shutdown whatever logging back end I'm using? For log4j it would call - org.apache.log4j.LogManager.getLoggerRepository().shutdown(); For logback it would call - loggerContext.stop() Other back ends - ??? This is required to allow me to not reference logging back ends explicitly in my code to shutdown successfully without losing events.

[Bug 266] New: Memory Leak: Clearing MDC context with Log4J

http://bugzilla.slf4j.org/show_bug.cgi?id=266 Summary: Memory Leak: Clearing MDC context with Log4J Product: SLF4J Version: 1.6.x Platform: All OS/Version: All Status: NEW Severity: major Priority: P1 Component: Implementations AssignedTo: slf4j-dev(a)qos.ch ReportedBy: f.bantner(a)axon-e.de Recently after a long time log4j got it's problem with clearing the MDC context and the underlying ThreadLocal Hashmap fixed. S. https://issues.apache.org/bugzilla/show_bug.cgi?id=50486 This fixed a long running Problem with Tomcat freeing memory on reload. In order to do so, log4j's MDC got the clear method with 1.2.16 and with 1.2.17 fixed it so that it works. Log4j has an MDC adaptor for Log4J and it's own clear method. But instead of calling Log4J's clear it implements essentially (MDC.getContext()).clear() which only clears the HashMap but doesn't remove it from the ThreadLocal context resulting in a MemroryLeak. Short workaround: Instead of calling slf4j's MDC.clear() call log4j's MDC.clear() (but that is the exact opositit of what slf4j is made for) Simple Fix: change log4j's mdc adaptor to call MDC.clear() instead of MDC.getContext().clear(). More complex fix: If backward compatibility is an issue (like it was für log4j) than log4js solution can be applied here: Instead of calling MDC.clear() directly call it via reflexion if it exists and otherwise keep calling MDC.getContext().clear(). -- Configure bugmail: http://bugzilla.slf4j.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

[Bug 317] New: erroneous migration turns returned Logger into LoggerFactory

http://bugzilla.slf4j.org/show_bug.cgi?id=317 Priority: P5 Bug ID: 317 Assignee: slf4j-dev(a)qos.ch Summary: erroneous migration turns returned Logger into LoggerFactory Severity: normal Classification: Unclassified OS: Windows 2000 Reporter: garret(a)globalmentor.com Hardware: PC Status: NEW Version: 1.7.x Component: slf4j-migrator Product: SLF4J The migrator turns this: public Logger getLogger() { return logger; } into this: public LoggerFactory.getLogger() { return logger; } I guess the migrator must be using some naive regex---but I would have thought it would have at least prevented whitespace in matching "Logger.getLogger(". -- You are receiving this mail because: You are the assignee for the bug.
