Robert Schaft commented on LOG4J2-435:
--------------------------------------
You might ask: What does all this has to do with my example? Your examples
could be mapped the one or the other way on the two shown Gedankenexperiments.
Except that you made some elements implicit:
- {{<IfAny>}} is effectively an {{<If>}} with an implicit {{<Or>}} combination
of all contained conditions.
- {{<IfAll>}} is effectively an {{<If>}} with an implicit {{<And>}} combination
of all contained conditions.
- {{<ThenAlsoCheck>}} is effectively - now it becomes strange - a
{{<Then><IfAll>}}, which maps to {{<Then><If><And>}}
- You simply omitted {{<Then><DeleteIt/></Then>}}. But even if it is implicit,
its strangeness remains (expression with side effects instead of a boolean
expression).
- {{<Delete>}} contains implicitly an {{<If><And>}} with all the conditions.
> Feature request: auto-delete older log files

> Key: LOG4J2-435
> URL: https://issues.apache.org/jira/browse/LOG4J2-435
> Project: Log4j 2
> Issue Type: Improvement
> Reporter: Arkin Yetis
> Assignee: Remko Popma
> Labels: Rollover
> Fix For: 2.5
>
> Attachments: LimitingRolloverStrategy.java, SizeParser.java
>
>
> Original description:
> {quote}
> DefaultRolloverStrategy max attribute only applies if you have a %i in the
> file pattern. This request is to enhance DefaultRolloverStrategy or another
> appropriate component to allow a max number of files limit to apply across
> days/months/years when a filePattern includes a date pattern.
> {quote}
> ----
> One of the most requested features is to add the ability to Log4j to "clean
> up" older log files. This usually means deleting these files, although it
> could also mean moving them to a different location, or some combination of
> these.
> Users have different requirements for selecting the files to clean up. A
> common request is the ability to keep the last X number of log files. This
> works well if rollover is only date based but may give undesired results with
> size based rollover.
> Another factor to consider is that the directory containing the log files may
> contain the log files for multiple appenders, or even files unrelated to
> logging.
