NIFI-15907 Handle PROPERTY_PARAMETERIZATION_REMOVED as Local Change (#11207)
Signed-off-by: David Handermann <[email protected]>
> PROPERTY_PARAMETERIZATION_REMOVED showing as local change
> ---------------------------------------------------------
>
> Key: NIFI-15907
> URL: https://issues.apache.org/jira/browse/NIFI-15907
> Project: Apache NiFi
> Issue Type: Bug
> Components: Flow Versioning
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> When a processor's _migrateProperties_ removes a property and the existing
> flow had that property bound to a parameter (e.g. {*}#\{MyParam}{*}), the
> registry-side snapshot still carries the parameter reference while the local
> side no longer has the key at all.
> In {_}StandardFlowComparator.compareProperties{_}, this case emits
> *PROPERTY_PARAMETERIZATION_REMOVED* rather than {*}PROPERTY_REMOVED{*},
> because *valueA* is a bare parameter reference and *valueB* is null:
> {code:java}
> } else if (valueA != null && valueB == null) {
> if (isParameterReference(valueA)) {
>
> differences.add(difference(DifferenceType.PROPERTY_PARAMETERIZATION_REMOVED,
> ...));
> } else {
> differences.add(difference(DifferenceType.PROPERTY_REMOVED, ...));
> }
> }
> {code}
> The environmental-change gate _FlowDifferenceFilters.isStaticPropertyRemoved_
> only matches {*}PROPERTY_REMOVED{*}, so the parameterized variant survives
> the filter and shows up as a local modification.
