Thanks @dvehar , the change looks great.
I left some comments regarding the unit tests, we also need an integration test that check that setting two inner hits with the same name throws an exception during the execution of the query. Can you add one in NestedIT for instance ?

Can you use IllegalArgumentException e = expectThrows(IllegalArgumentException.class, () -> queryBuilder.extractInnerHitBuilders(Collections.singletonMap("some_name", null)); instead ?

Can you change the test to use the static function InnerHitContextBuilder#extractInnerHits to retrieve the builders ? It's the function we use to build the inner hits map.

I'll work on the integration test soon

@jimczi Could you provide some guidance as to what my test case should look like?

I've tried a few things but can't seem to get NestedQueryBuilder::extractInnerHitBuilders to be called. I'll keep working on it meanwhile.

jimczi · 2019-01-24T10:25:50Z

I've tried a few things but can't seem to get NestedQueryBuilder::extractInnerHitBuilders to be called.

I tested locally and the following query failed with the check that you added in this pr:

SearchResponse response = client().prepareSearch("idxduplicatehitnames")
          .setQuery(boolQuery()
              .must(matchAllQuery())
              .should(nestedQuery("nested_type", matchAllQuery(), ScoreMode.None).innerHit(new InnerHitBuilder()))
              .should(nestedQuery("nested_type", matchAllQuery(), ScoreMode.None).innerHit(new InnerHitBuilder()))
          ).get();

You should not test aggregations, that's a different issue but we should not allow inner hits in the filter aggregations. They are not supported there so extractInnerHitBuilders is never called.

dvehar · 2019-01-25T07:27:02Z

@jimczi looks good?

jimczi

Thanks for updating @dvehar . I left more comments.

jimczi · 2019-01-25T08:41:04Z

modules/parent-join/src/main/java/org/elasticsearch/join/query/HasChildQueryBuilder.java

we should use the same format for the message than the option in the request, can you change innerHits to [inner_hits] ?

jimczi · 2019-01-25T08:41:11Z

modules/parent-join/src/main/java/org/elasticsearch/join/query/HasParentQueryBuilder.java

Same here, innerHits-> [inner_hits]

jimczi · 2019-01-25T08:41:30Z

server/src/main/java/org/elasticsearch/index/query/NestedQueryBuilder.java

innerHits -> [inner_hits]

jimczi · 2019-01-25T08:46:05Z

modules/parent-join/src/main/java/org/elasticsearch/join/query/HasChildQueryBuilder.java

If innerHitBuilder.getName() is null we use the type as the name (see below). Can you build the name first and check in the inner hits map with the inferred one ?:

String name = innerHitBuilder.getName() != null ? innerHitBuilder.getName() : type; if (innerHits.containsKey(name)) { ...

jimczi · 2019-01-25T08:47:03Z

modules/parent-join/src/main/java/org/elasticsearch/join/query/HasParentQueryBuilder.java

See above, we should check with the inferred name as well if innerHitBuilder.getName is null.

jimczi · 2019-01-25T08:47:43Z

server/src/main/java/org/elasticsearch/index/query/NestedQueryBuilder.java

here the path is used if the name is null, can you infer the name first and then check inside the map ?

jimczi · 2019-01-25T08:49:26Z

server/src/test/java/org/elasticsearch/search/aggregations/bucket/NestedIT.java

This test should fail, we use the path of the nested field as the name when it is not provided so we should also detect the duplication here.

Ah ok. When you posted the example here I was thinking it should not fail. I'll fix this up.

ah ok, sorry it was not clear

no worries, I think it was just my limited understanding of things.

Thanks @dvehar , the changes look good to me. The tests are failing on unrelated issues so can you merge master in your branch (a simple merge) to make sure that we run the tests with the latest fixes ?

@jimczi
Some builds are failing on org.elasticsearch.upgrades.FullClusterRestartIT.testRecovery(FullClusterRestartIT.java:842) because of java.lang.AssertionError: expected version to be one of [8.0.0,7.6.0] but was p 0 testrecovery 7.7.0. I can look into it more later. Let me know if you are aware of the issue

javanna · 2019-01-29T14:59:28Z

hi @dvehar that last test that was failing is now addressed. could you merge master in so we can re-run tests and hopefully have a green build? ;)
