Ralph Goers commented on LOG4J2-2517:
-------------------------------------
OK. I reverted my change and ran the app multiple times using 2.11.2-SNAPSHOT.
I do notice that sometimes it does rollover the file depending on how much time
elapses between the time the RollingFileManager creates the file and when
OnStartup is initialized. If it is in the same millisecond it does not roll
over. It rolled over the file properly every time I ran it. This is on my
MacBook Pro.
> RollingFileManager OnStartupTriggeringPolicy never rolls the file on startup

> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.11.1
> Reporter: Jon Hanson
> Priority: Minor
> Attachments: log4j2.json, log4j2_debug.log

>
> I'm trying to get log4j2 (V2.11.1) to roll the existing log file at startup
> before it starts logging into a new file. My config is atached to the jira.
> I'm using a RollingFileManager with a OnStartupTriggeringPolicy with
> minSize=0, which, according to the documentation should be sufficient.
> However what i'm finding is that at startup, the
> {{OnStartupTriggeringPolicy}} class {{initialize}} method compares the
> timestamp of the log file to the JVM startup, and if the log file time is
> after the start-up time then it won't roll the file. If I step through the
> code then I see that at the point that check is made the file time is always
> after the JVM start time, because log4j2 appears to have already opened the
> file for writing at that point.
