Carsten Ziegeler resolved SLING-12640.
--------------------------------------
Resolution: Fixed
> Setting Sling filter service property sling.filter.scope to an invalid value
> does not disable the filter.
> ---------------------------------------------------------------------------------------------------------
>
> Key: SLING-12640
> URL: https://issues.apache.org/jira/browse/SLING-12640
> Project: Sling
> Issue Type: Bug
> Components: Engine
> Affects Versions: Engine 2.15.16
> Reporter: Rakesh Kumar
> Assignee: Carsten Ziegeler
> Priority: Major
> Fix For: Engine 2.16.2
>
>
> I have created a filter service and provided the value of
> *sling.filter.scope* as some arbitrary string({*}MyDisabledFilter{*})
> I followed the disabling mechanism mentioned here -
> [https://sling.apache.org/documentation/the-sling-engine/filters.html#disabling-filters-1]
> But the filter is still registered by Sling as a request filter.
> I was looking at the
> {code:java}
> org.apache.sling.engine.impl.filter.ServletFilterManager{code}
> code and found that if an invalid value is specified for *sling.filter.scope*
> property, then the filter is still registered as a REQUEST scoped filter as
> some fallback.
> {code:java}
> final String[] scopes =
>
> Converters.standardConverter().convert(scopeValue).to(String[].class);
> final FilterPredicate predicate = new FilterPredicate(reference);
> boolean used = false;
> for (String scope : scopes) {
> scope = scope.toUpperCase();
> try {
> FilterChainType type =
> FilterChainType.valueOf(scope.toString());
> getFilterChain(type).addFilter(filter, predicate, serviceId,
> order, orderSource, mbean);
> if (type == FilterChainType.COMPONENT) {
> getFilterChain(FilterChainType.INCLUDE)
> .addFilter(filter, predicate, serviceId, order,
> orderSource, mbean);
> getFilterChain(FilterChainType.FORWARD)
> .addFilter(filter, predicate, serviceId, order,
> orderSource, mbean);
> }
> used = true;
> } catch (final IllegalArgumentException iae) {
> log.warn("Filter service {} has invalid value {} for scope.
> Value is ignored", reference, scope);
> }
> }
> if (!used) {
> log.warn(
> "Filter service {} has been registered without a valid {}
> property. Using default value.",
> serviceId,
> EngineConstants.SLING_FILTER_SCOPE);
> getFilterChain(FilterChainType.REQUEST).addFilter(filter,
> predicate, serviceId, order, orderSource, mbean);
> } {code}
>
> This seems to be contradictory to the official documentation.
> Please let me know if I am missing something.
> [~cziegeler] can you please look at this?
> Thanks,
