Hehe exactly. I guess then, if i find a solution (i have something in mind)
which is a bit more general, i should create a new issue for the structural
problem and then do the PR against that, fixing the policies along the way.
And of course, will write tests against it :)

The best bet is to create a pull request at GitHub. Then ensure there is a unit
test that covers this issue and that it, and all the other unit tests, work
correctly.
The main problem here is that, as you noticed, all these strategies and
policies are somewhat co-dependent. Sometimes it feels like playing
whack-a-mole as when one bug is fixed another pops up somewhere else.

[~ggregory] since i have no experience with how apache / log4j handles problems
on this scope, what should i do now? Since this is kind of multiple problems
all originally caused by an architectural problem.

I ultimately got alteast cron and onstartup to work correctly with eachother by
implementing my customized version of them and DefaultRolloverStrategy (aswell
as FileExtension, for the PS mentioned above).
But i think something should definitely be straightened / redesigned here.
I attached the classes for the curious.

I found several issues which are all somewhat related to the problem.
Inside CronTriggeringPolicy there are several calls to the PatternProcessor,
which override its "normal" keeping track of timestamps. And another call
inside its custom rollover() method also forces a timestamp on the manager,
which in turn does the same - applying that false timestamp to the
PatternProcessor.
And there also is a bug in OnStartupTriggeringPolicy: It never sets the current
file time for the PatternProcessor. Meaning if any other policies depend upon
that value set, they will fail.
And also PatternProcessor.getNextTime() - which according to it's javadoc
should only return the next potential rollover time) - just overwrites
prevFileTime with nextFileTime?! That can't be correct?
Honestly it kind of seems like all the policies (i looked at startup,
timebased, cron, sizebased) are just overwriting the timestamps of
PatternProcessor so that they work if only they themselves are used. Which i
guess is because DefaultRolloverStrategy uses
{code:java}
PatternProcessor.formatFileName((final StrSubstitutor subst, final
StringBuilder buf, final Object obj)){code}
and not
{code:java}
PatternProcessor.formatFileName(final StrSubstitutor subst, final StringBuilder
buf, final boolean useCurrentTime, final Object obj) { {code}
This means that, even if the timestamps would be set correctly by the policies,
the used file name for the to-be-archived file would contain the timestamp of
the *previously* archived file and thus overwrite it.
I think maybe RollingFileManager should actually do some managing and update
the timestamps to be used by the PatternProcessor, so that the policies don't
have to manage that.
PS:
org.apache.logging.log4j.core.appender.rolling.FileExtension has several
methods on default visibility, which is problematic if one wants to extend
AbstractRolloverStrategy.

Oh i just noticed, CronTriggeringPolicy also inserted the day-of-month from
yesterday. So yeah, definitely bugged.

I'm pretty sure this problem is still present in the latest log4j2 version. I
used the following RollingFileAppender:
{code:java}
${LOG_DIR}system.log
${LOG_DIR}system%d{-MM-dd HH.mm.ss}.log.zip
{code}
I then started my program 3 times before 13.40, the last launch i let run past
13.40.
Here are the created files at 13.50:
||file name||comment||first timestamp||last timestamp||
|system.log|The current file|13:40:51|13:51:26|
|system2022-08-09 13.40.00.log.zip|Triggered by
CronTriggeringPolicy|13:35:33|13:39:51|
|system2022-08-10 13.33.15.log.zip|Triggered by OnStartupTriggeringPolicy
I just stopped the program.|13:33:15|13:34:15|
|system2022-08-10 13.32.33.log.zip|Triggered by OnStartupTriggeringPolicy
I just stopped the program.|13:32:33|13:32:49|
So obviously there is a discrepency in behavior here.
It seems to me that OnStartupTriggeringPolicy uses the timestamp at the start
of the log file which it will rollover.
On the other hand CronTriggeringPolicy seems to use exactly the fixed the
numbers from "schedule" and only inserts the placeholders ( * ).
Atleast personally i expected CronTriggeringPolicy to use the same behavior as
OnStartupTriggeringPolicy and use the timestamp at the start of the log file.
Note though that my experience with log4j2 is somewhat limited, so i don't know
how the other policies behave.
