What this PR does / why we need it:
Since the recent merge of #1714,
tagsandsourcefields are now part of both the grpc and json outputs. However, the semantic of the json output is not clear in some corner cases, such as when no tags are defined in a rule. Also, users can't configure whether to includetagsin the json outputs or not, which instead is possible for theoutputfield. Moreover, no test cases are yet present for asserting the expected outcome of these corner cases. These issues were reported in #1714 (comment) by @leodido (thank you!!)As such, this PR contributes with the following:
json_include_tags_propertyconfiguration option, so that users can decide whether to includetagsin the json outputs or not. By default this is set totrueto not introduce breaking changes for clients that currently expect the field to be present.Additional Context:
The table below describes the expected outcomes in the json outputs by using the new configuration option.
json_include_tags_property = truejson_include_tags_property = falsetags=[]tagsfieldtags=[...]tagsfieldThese cases are covered by the following tests:
json_output_empty_tags_property: Case (1)json_output_no_tags_property: Cases (2) and (4)stdout_output_json_strict: Case (3)Does this PR introduce a user-facing change?:
