Matt Sicker commented on LOG4J2-2804:
-------------------------------------
The best bug report is one with a failing unit test that would pass once the
bug was fixed. Anything less than that requires developer time to diagnose what
the problem is from log messages and config files, and such issues are likely
to take longer to address than ones with a very easy way to verify the bug and
the fix. Essentially, if you want this done ASAP, please provide the test(s);
otherwise, this will get picked up as usual (i.e., later for some definition of
later).

> Key: LOG4J2-2804
> URL: https://issues.apache.org/jira/browse/LOG4J2-2804
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.13.1
> Reporter: André Pinto
> Priority: Major
>
> When there are both size based and time based triggering policies, if the
> size based policy is triggered, the file is named as if the time based policy
> was triggered.
> Example config:
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="WARN" name="Mux">
> <Properties>
> <Property name="LOG_DIR">logs</Property>
> </Properties>
> <Appenders>
> <Console name="Console" target="SYSTEM_OUT"/>
> <RollingRandomAccessFile name="main"
> fileName="${LOG_DIR}/main-current.log-active"
>
> filePattern="${LOG_DIR}/main-%d{yyyy-MM-dd-HH.mm.ss}.log"
> ignoreExceptions="false"
> immediateFlush="false"
> bufferSize="1048576">
> <PatternLayout>
> <Pattern>%m\n</Pattern>
> </PatternLayout>
> <Policies>
> <SizeBasedTriggeringPolicy size="256 B" />
> <TimeBasedTriggeringPolicy interval="3600" />
> </Policies>
> <DefaultRolloverStrategy fileIndex="nomax" />
> </RollingRandomAccessFile>
> </Appenders>
> <Loggers>
> <Root level="OFF">
> <AppenderRef ref="Console" />
> </Root>
> <Logger name="main" level="ALL" additivity="false">
> <AppenderRef ref="main"/>
> </Logger>
> </Loggers>
> </Configuration>
> {code}
> With this configuration if I start writing log entries to the "main" logger
> at 2020-03-09 13:00.00 and immediately trigger the SizeBasedTriggeringPolicy
> (256 bytes), the name of the file that is rolled over will be:
> main-2020-03-09-14.00.00
> as if the rollover operation had been triggered by the time policy.
