[Security Solution] Adds diff algorithm and unit tests for `query` fields #190179

dplumlee · 2024-08-08T19:04:16Z

Summary

Related ticket: #187658

Adds diff algorithm for all the grouped query fields we have in the DiffableRule type and prebuilt rule upgrade workflow. These include kql_query (both inline and saved query), eql_query, and esql_query. Also adds unit tests for all three algorithms.

@dplumlee I'm gonna continue reviewing next week cause I gotta handle some SDHs today but:

the query field shouldn't be mergeable. We should treat it as a single line string field.
since filters is an array, I was thinking that we might be able to apply some more clever merging logic, to have better UX in a case, for example, where a user just adds a filter to a list of existing filters; and therefore not throwing a conflict but just merging the current and target versions. However:
- more complex scenarios will be increasingly difficult to decide what to do, since each filter is a really complex object
- there's only 15 prebuilt rules that have filters in their definitions. It looks it doesn't make a lot of sense to put a lot of effort into this right now.

So let's just use the simple diffing algorithm for the filters field for now, as you are already doing. I created a ticket so we can revisit this in the future.

Not sure I understand these two scenarios as described here:

returns target_version as merged output if all versions are the same: Do you mean here if current and target versions have the same type?

returns target_version as merged output if all versions are different: Did you mean here if current and target versions have different type? In that case it doesn't match the input data, which are both of saved_query type.

Yeah I meant if both versions had the same/different type fields, I'll switch it over 👍

This is unused now, right? Let's delete it for now then.
