This change adds tests for the aggregation parsing that try to simulate that we
can parse existing aggregations in a forward compatible way in the future,
ignoring potential newly added fields or substructures to the xContent response.
This commit adds a NamedXContentProvider interface that can
be implemented by plugins or modules using Java's SPI feature
in order to provide additional NamedXContent parsers to external
applications like the Java High Level Rest Client.
This commit adds back "id" as the key within a script to specify a
stored script (which with file scripts now gone is no longer ambiguous).
It also adds "source" as a replacement for "code". This is in an attempt
to normalize how scripts are specified across both put stored scripts and script usages, including search template requests. This also deprecates the old inline/stored keys.
This commit adds a `doc_count` field to the response body of Matrix
Stats aggregation. It exposes the number of documents involved in
the computation of statistics, a value that can already be retrieved using
the method MatrixStats.getDocCount() in the Java API.
This will be useful for the high level client to add support for the matrix stats aggregation, as we will ship with this jar by default like we do for parent-join-client which is aligned with distributing core with the modules already included.

This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge
Throw error when skip or do sections are malformed, such as they don't start with the proper token (START_OBJECT). That signals bad indentation, which would be ignored otherwise. Thanks (or due to) our pull parsing code, we were still able to properly parse the sections, yet other runners weren't able to.

* [TEST] fix indentation in matrix_stats yaml tests
* [TEST] fix indentation in painless yaml test

* [TEST] fix indentation in generated docs yaml tests
* [TEST] fix indentation in multi_cluster_search yaml tests
This commit upgrades the checkstyle configuration from version 5.9 to
version 7.5, the latest version as of today. The main enhancement
obtained via this upgrade is better detection of redundant modifiers.

It is no longer needed. It used to contain a lot of strings
used by serialization but those have since been removed. Now
it is just another thing to pass around that we don't really
need.
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.
* Remove `ClientYamlTestFragmentParser`. Isn't used any more.
* Remove `ClientYamlTestSuiteParseContext`, replacing it with some static utility methods.
I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
The creation of the `ValuesSource` used to pass `DateTimeZone.UTC` as a time
zone all the time in case of empty fields in spite of the fact that all doc
value formats but the date one reject this parameter.
This commit centralizes the creation of the `ValuesSource` and adds unit tests
to it.
Closes#22009
This class is just a wrapper around `SearchContext`, so let's use
`SearchContext` directly. The change is mechanical, except the
`ValuesSourceConfig` class, where I moved the logic to get a `ValuesSource`
given a config.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
This fixes a bug in the RunningStats class for the matrix stats aggregation module. doc counts were not being searlized which means they were only computed the first time the aggregation was computed. This was causing incorrect results when the aggregation was pulled from cache.
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
* Remove outdated aggregation registration method
* Remove AggregationStreams
* Adds StreamInput#readNamedWriteableList and
StreamOutput#writeNamedWriteableList convenience methods. We strive to
make the reading and writing from the streams terse so they are easier
to scan visually.
* Remove PipelineAggregatorStreams
* Remove stream info from InternalAggreation.Type
* Remove InternalAggregation#type
* Remove Streamable from PipelineAggregator
* Remove Streamable from MultiBucketsAggregation.Bucket
creation in the REST tests, as we no longer need it due
to index creation now waiting for active shard copies
before returning (by default, it waits for the primary of
each shard, which is the same as ensuring yellow health).

In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.
This commit adds a new aggs-matrix-stats module. The module presents a new class of aggregations called Matrix Aggregations. Matrix aggregations work on multiple fields and produce a matrix as output. The first matrix aggregation provided by the module is matrix_stats aggregation. This aggregation computes the following statistics over a set of fields:
* Covariance
* Correlation
For completeness (and interpretation purposes) the following per-field statistics are also provided:
* sample count
* population mean
* population variance
* population skewness
* population kurtosis
