Remove comma-separated feature parsing for GetIndicesAction by dakrone · Pull Request #24723 · elastic/elasticsearch

dakrone · 2017-05-16T21:50:57Z

This removes the parsing of things like GET /idx/_aliases,_mappings, instead,
a user must choose between retriving all index metadata with GET /idx, or only
a specific form such as GET /idx/_settings.

Relates to (and is a prerequisite of) #24437

@jasontedor could you take a look at this? This is the PR you asked me to separate from #24437

docs/reference/indices/get-index.asciidoc

This could just be changed to

GET twitter?filter_path=*.settings,*.mappings

I think we could, but not sure it's worth it since I think this is a very minor edge case that people use.

core/src/main/java/org/elasticsearch/rest/action/admin/indices/RestGetAllMappingsAction.java

Under what circumstances would the mappings for an index be null (as opposed to an empty map)? It seems the default for GetIndexResponse is to always have an empty map for mappings (and aliases and settings) and it would only get assigned to a non-null map.

I don't think they ever would be, this is a carryover from when I copied this from the other method. I'll remove it.

rest-api-spec/src/main/resources/rest-api-spec/test/indices.get/10_basic.yml

I'm not clear on why this test was eliminated, because we still support {index}/_mapping by its own without the comma-separated multi values?

This test was eliminated because it was for the indices.get API, whereas we already have tests for the indices.get_mapping API (in another file), so this was just a duplicate test.

Ditto to the comment above

Same about the duplicated test

rest-api-spec/src/main/resources/rest-api-spec/api/indices.get.json

Should we also add rest specs and yaml tests for the new REST endpoints introduced in this PR?

Interestingly enough, we already do have these endpoints in the spec, they just weren't in this file :)

Thanks @abeyad, I pushed some commits addressing your feedback

LGTM, thanks @dakrone

thank you @abeyad :)

Are we going to also deprecate this in 5.x?

dakrone · 2017-06-02T22:08:33Z

Are we going to also deprecate this in 5.x?

Good idea, I'll open a PR

This is the deprecation logging and documentation for 5.x related to elastic#24723. It logs when a user does a request like: ``` GET /index/_alias,_mapping ```

Relates to #24723

* Add deprecation logging for comma-separated feature parsing This is the deprecation logging and documentation for 5.x related to #24723. It logs when a user does a request like: ``` GET /index/_alias,_mapping ```

Previously this would output: ``` GET /test-1/_mappings { } ``` And after this change: ``` GET /test-1/_mappings { "test-1": { "mappings": {} } } ``` To bring parity back to the REST output after elastic#24723. Relates to elastic#25090

Previously in elastic#24723 we changed the `_alias` API to not go through the `RestGetIndicesAction` endpoint, instead creating a `RestGetAliasesAction` that did the same thing. This changes the formatting so that it matches the old formatting of the endpoint, before: ``` GET /test-1/_alias { } ``` And after this change: ``` GET /test-1/_alias { "test-1": { "aliases": {} } } ``` This is related to elastic#25090

Previously this would output: ``` GET /test-1/_mappings { } ``` And after this change: ``` GET /test-1/_mappings { "test-1": { "mappings": {} } } ``` To bring parity back to the REST output after #24723. Relates to #25090
