-------------------------------------
Where are we on this one?
> Reconfiguring statusLogger to a higher level doesn't work correctly
> -------------------------------------------------------------------
>
> Key: LOG4J2-945
> URL: https://issues.apache.org/jira/browse/LOG4J2-945
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1
> Reporter: Stefan Wehner
> Priority: Minor
> Attachments: StatusLoggerBenchmark.java, callback_on_reconfig.patch,
> log4j2-status-perf.xml, remove_listeners_level.patch
>
>
> When reconfiguring log4j and changing the level of the status logger to a
> higher level - e.g. from WARN to DEBUG, it doesn't work correctly.
> Steps to reproduce:
> # Configure from log4j2.xml containing:
> {code}
> <Configuration status="WARN" monitorInterval="5">
> ...
> {code}
> # With the app running, change status to a higher level:
> {code}
> <Configuration status="DEBUG" monitorInterval="5">
> ...
> {code}
> # Observe that the log config is reloaded, but no debug messages for the
> status logger appear.
> From what I've seen this is because the {{StatusConfiguration.initialize()}}
> reconfigures the listeners' level
> [StatusConfig:193|https://git-wip-us.apache.org/repos/asf?p=logging-log4j2.git;a=blob;f=log4j-core/src/main/java/org/apache/logging/log4j/core/config/status/StatusConfiguration.java;h=4d2ee51b4cf5dcb6f62029fe307093a759bf0af7;hb=HEAD#l193]
> But it doesn't update the {{listenersLevel}} field that the {{StatusLogger}}
> uses for checking if the logger is enabled (I understand this should be the
> maximum of all of the listener's levels)
> [StatusLogger:273|https://git-wip-us.apache.org/repos/asf?p=logging-log4j2.git;a=blob;f=log4j-api/src/main/java/org/apache/logging/log4j/status/StatusLogger.java;h=39d447d9793ca08a7d86b9eaaf6ef3dd406cf9a2;hb=HEAD#l273]
> So in this case the listenersLevel is still at WARN, even though the console
> listener has a DEBUG level, and all the log messages are ignored because
> isEnabled(DEBUG) returns false.
