Ralph Goers commented on LOG4J2-2669:
-------------------------------------
I just noticed that in the log4j configuration you have a delete of
c:/temp/test.log. Why on earth would you want to delete the file you are
logging to? That is bound to cause problems. Did you mean to delete the file
that was rolled after 10 days?
> RollingFileAppender is not rolled by date correctly

> Key: LOG4J2-2669
> URL: https://issues.apache.org/jira/browse/LOG4J2-2669
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders, Core
> Affects Versions: 2.11.2, 2.12.0
> Reporter: Edith Chui
> Priority: Major
> Attachments: log4j2.issue.zip, tested.zip

> Since version 2.11.2, the log42 library is unable to roll the file by date.
> It will move the previous day's log to an existing log backup file with date
> different to the log date.
> e.g. Assume previous day is 1 Jan, and some logs with log date 1 Jan were
> written in test.log already. Running application on 2 Jan and continue do
> some logging, the previous day log will be moved to 31 Dec and the log on 31
> Dec was erased. After observed for few more days, the rolling is still
> incorrect.
> Using the same configuration, no such problem was occurred in 2.11.1.
> Sample :
> {code:java}
> <RollingFile name="fileAppender" fileName="C:/temp/test.log"
> filePattern="C:/temp/test_%d{yyyy-MM-dd}.bak">
> <PatternLayout pattern="%d{ISO8601} [%p] [%t] [%C] at [${hostName}] %m\r\n"
> />
> <Policies>
> <TimeBasedTriggeringPolicy interval="1" modulate="true" />
> </Policies>
> <DefaultRolloverStrategy>
> <Delete basePath="C:/temp/test.log" maxDepth="1">
> <IfLastModified age="10d" />
> </Delete>
> </DefaultRolloverStrategy>
> </RollingFile>{code}
