-------------------------------------
Summary: 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
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.
