Ralph Goers commented on LOG4J2-2669:
-------------------------------------
Let me be clear. Your delete stanza is wrong. You are deleting the file that
log4j is writing to. I believe it should be
{code:java}
<Delete basePath="C:/temp/" maxDepth="1">
<IfFileName glob="test_*.bak"/>
<IfLastModified age="10d" />
</Delete>{code}
As for minute, hour, or day, it doesn't matter. File rolling works the same
way. It is more convenient to change it to roll every minute than screwing up
my laptop by changing the date. The fact of the matter is, my tests show your
scenario works fine after the mistake above is corrected.

> 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}
