This looks really good. I could find nothing wrong with the expected
behavior as well as compatibility issues which were well-thought out. Here are
some of the tests I performed:
Changed this PR's code to modify a controller service (CS), specifically
CSVReader, to issue DEBUG, INFO, WARN and ERROR log messages when enabled.
Built and installed.
Instantiated CSVReader within a process group (PG) and set the Bulletin
Level to DEBUG
Enabled the CS and observed all four bulletins on the PG's listing of
Controller Services. Also observed them on the Bulletin Board.
Repeat, changing the Bulletin Level to INFO, then WARN, then ERROR. All
confirmed to behave as expected with bulletin visibility.
Copy/paste the PG.
> The bulletin level for the CS remained as DEBUG, and behavior confirmed.
Version controlled the PG to NiFi Registry of this PR (1.17.0-SNAPSHOT).
Then, instantiated the flow from Registry.
> The bulletin level for the CS remained as DEBUG, and behavior confirmed.
Version controlled the PG to NiFi Registry, 1.16.1. Then, instantiated the
flow from Registry.
> The bulletin level for the CS returned to WARN as expected, and
corresponding behavior confirmed.
For backward compatibility, installed NiFi 1.16.1 placing flow.xml.gz and
flow.json.gz in the conf directory (and other required config updates to enable
NIFi to start.) NiFi started without issue. CS issued bulletins at the WARN
level.
The only comment is that TRACE is not an option. However, it is not a
Bulletin Level option for processors either, so I think this is fine. If you're
interested in TRACE level, you're probably looking at - or have the ability to
look at - the log file directly.
