Dieter Mueller commented on LBCORE-147:
---------------------------------------

I just tested it with current version 0.9.26 and verified the bug.

config:
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- rollover daily -->
      <fileNamePattern>foo-%d{yyyy-MM-dd}.%i.log.zip</fileNamePattern>
      <maxHistory>4</maxHistory>
      <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
        <maxFileSize>20MB</maxFileSize>
      </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>

But the main key is, that the application did not run for some days:
e.g. Today (09.12.) I had logfiles from 1.12, 2.12., 3.12, 4.12. 5.12., 6.12.
When I started the app, then the logfile from 4.12. (older than 4 days) was deleted, but the older ones (1.12. 2.12., 3.12)
were not deleted.

It seems, that logback calculates the ONE day to be deleted. It does not look back into the past, which is reasonable to me,
because how far it should look back?

Dieter Mueller
