Commit 39483b9c121b11abbc00f12232075ef4328a17ee in nifi's branch
refs/heads/main from Mark Payne

NIFI-9716, NIFI-9577: Addressed issue in the PathFilter for GetFile / ListFile.
For any file that is found in the Input Directory directly, it was previously
being listed/fetched even if it didn't match the PathFilter. Additionally,
updated the code to create a new File FIlter for every invocation of onTrigger.
This was necessary for NIFI-9577 because the directory to monitor supports
Expression Language and as a result may change from invocation to invocation,
if using a function such as now() but the PathFilter would always relativize
the path based on the value that was obtained when the processor was scheduled.

This closes #5788.

> Issue Type: Bug
> Components: Core Framework

> Hello,
> under special circumstances GetFile and ListFile do not process files.
> To reproduce the problem I attached a template:
> [^GetFile-ListFile-Problem.xml]
> The template generates every minute (0 0/1 * ? * MON-SAT) a flow file of 10B
> and stores it locally in a *new* ( ! ) folder:
> tmp/prod/cltest/${now():format('yyyyMMdd-HHmm')}/gaz/artikel.
> GetFile and ListFile run about 30 seconds after GenerateFlowFile processor(35
> 0/1 * ? * MON-SAT). For both processors the input directory is:
> tmp/prod/cltest/${now():format('yyyyMMdd-HHmm')}/.
> Path Filter is set to: ((anzg)|(gaz))\/artikel
> The first time when the processors are running the result set of each
> processor contains 1 file.
> After the first run the result will always be empty. There occurs no error.
> It's only empty.
> !workflow.png|width=813,height=449!
> We use NiFi versions 1.11.4 and 1.15.2. Both have the same problem.
> Could you please have a look on it.
> Thank you and regards
> Christoph
