Removed `parse(String index, String type, String id, BytesReference source)` in DocumentMapper.java and replaced all of its use in Test files with `parse(SourceToParse source)`.
`parse(String index, String type, String id, BytesReference source)` was only used in test files and never in the main code so it was removed. All of the test files that used it was then modified to use `parse(SourceToParse source)` method that existing in DocumentMapper.java
We have many version constants in master that have already been
released, but are still marked (by naming convention) as unreleased.
This commit renames those version constants.
We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.
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.
Relates #22960
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.
The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.
As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.
In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.
See #19388
Removes `AggregatorParsers`, replacing all of its functionality with
`XContentParser#namedObject`.
This is the third bit of payoff from #22003, one less thing to pass
around the entire application.
* 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.
Introduces `XContentParser#namedObject which works a little like
`StreamInput#readNamedWriteable`: on startup components register
parsers under names and a superclass. At runtime we look up the
parser and call it to parse the object.
Right now the parsers take a context object they use to help with
the parsing but I hope to be able to eliminate the need for this
context as most what it is used for at this point is to move
around parser registries which should be replaced by this method
eventually. I make no effort to do so in this PR because it is
big enough already. This is meant to the a start down a road that
allows us to remove classes like `QueryParseContext`,
`AggregatorParsers`, `IndicesQueriesRegistry`, and
`ParseFieldRegistry`.
The goal here is to reduce the amount of plumbing required to
allow parsing pluggable things. With this you don't have to pass
registries all over the place. Instead you must pass a super
registry to fewer places and use it to wrap the reader. This is
the same tradeoff that we use for NamedWriteable and it allows
much, much simpler binary serialization. We think we want that
same thing for xcontent serialization.
The only parsing actually converted to this method is parsing
`ScoreFunctions` inside of `FunctionScoreQuery`. I chose this
because it is relatively self contained.
This commit makes mapping updates atomic when multiple types in an index are updated. Mappings for an index are now applied in a single atomic operation, which also allows to optimize some of the cross-type updates and checks.
With this commit we enable the Jackson feature 'STRICT_DUPLICATE_DETECTION'
by default. This ensures that JSON keys are always unique. While this has
a performance impact, benchmarking has indicated that the typical drop in
indexing throughput is around 1 - 2%.
As a last resort, we allow users to still disable strict duplicate checks
by setting `-Des.json.strict_duplicate_detection=false` which is
intentionally undocumented.
Closes#19614
Our query DSL supports empty queries (`{}`), which have a different meaning depending on the query that holds it, either ignored, match_all or match_none. We deprecated the support for empty queries in 5.0, where we log a deprecation warning wherever they are used.
The way we supported it once we moved query parsing to the coordinating node was having an Optional<QueryBuilder> return type in all of our parse methods (called fromXContent). See #17624. The central place for this was QueryParseContext#parseInnerQueryBuilder. We can now remove all the optional return types and simply throw an exception whenever an empty query is found.
To get #22003 in cleanly we need to centralize as much `XContentParser` creation as possible into `RestRequest`. That'll mean we have to plumb the `NamedXContentRegistry` into fewer places.
This removes `RestAction.hasBody`, `RestAction.guessBodyContentType`, and `RestActions.getRestContent`, moving callers over to `RestRequest.hasContentOrSourceParam`, `RestRequest.contentOrSourceParam`, and `RestRequest.contentOrSourceParamParser` and `RestRequest.withContentOrSourceParamParserOrNull`. The idea is to use `withContentOrSourceParamParserOrNull` if you need to handle requests without any sort of body content and to use `contentOrSourceParamParser` otherwise.
I believe the vast majority of this PR to be purely mechanical but I know I've made the following behavioral change (I'll add more if I think of more):
* If you make a request to an endpoint that requires a request body and has cut over to the new APIs instead of getting `Failed to derive xcontent` you'll get `Body required`.
* Template parsing is now non-strict by default. This is important because we need to be able to deprecate things without requests failing.
This adds the `_primary_term` field internally to the mappings. This field is
populated with the current shard's primary term.
It is intended to be used for collision resolution when two document copies have
the same sequence id, therefore, doc_values for the field are stored but the
filed itself is not indexed.
This also fixes the `_seq_no` field so that doc_values are retrievable (they
were previously stored but irretrievable) and changes the `stats` implementation
to more efficiently use the points API to retrieve the min/max instead of
iterating on each doc_value value. Additionally, even though we intend to be
able to search on the field, it was previously not searchable. This commit makes
it searchable.
There is no user-visible `_primary_term` field. Instead, the fields are
updated by calling:
```java
index.parsedDoc().updateSeqID(seqNum, primaryTerm);
```
This includes example methods in `Versions` and `Engine` for retrieving the
sequence id values from the index (see `Engine.getSequenceID`) that are only
used in unit tests. These will be extended/replaced by actual implementations
once we make use of sequence numbers as a conflict resolution measure.

Supercedes #21480
P.S. As a side effect of this commit, `SlowCompositeReaderWrapper` cannot be
used for documents that contain `_seq_no` because it is a Point value and SCRW
cannot wrap documents with points, so the tests have been updated to loop
through the `LeafReaderContext`s now instead.
This adds a fromXContent method and unit test to the HighlightField class so we
can parse it as part of a serch response. This is part of the preparation for
parsing search responses on the client side.
For the record, I also had to remove the geo-hash cell and geo-distance range
queries to make the code compile. These queries already throw an exception in
all cases with 5.x indices, so that does not hurt any more.
I also had to rename all 2.x bwc indices from `index-${version}` to
`unsupported-${version}` to make `OldIndexBackwardCompatibilityIT`
happy.
Lucene 6.2 added index and query support for numeric ranges. This commit adds a new RangeFieldMapper for indexing numeric (int, long, float, double) and date ranges and creating appropriate range and term queries. The design is similar to NumericFieldMapper in that it uses a RangeType enumerator for implementing the logic specific to each type. The following range types are supported by this field mapper: int_range, float_range, long_range, double_range, date_range.
Lucene does not provide a DocValue field specific to RangeField types so the RangeFieldMapper implements a CustomRangeDocValuesField for handling doc value support.
When executing a Range query over a Range field, the RangeQueryBuilder has been enhanced to accept a new relation parameter for defining the type of query as one of: WITHIN, CONTAINS, INTERSECTS. This provides support for finding all ranges that are related to a specific range in a desired way. As with other spatial queries, DISJOINT can be achieved as a MUST_NOT of an INTERSECTS query.

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.
The `IndexService#newQueryShardContext()` method creates a QueryShardContext on
shard `0`, with a `null` reader and that uses `System.currentTimeMillis()` to
resolve `now`. This may hide bugs, since the shard id is sometimes used for
query parsing (it is used to salt random score generation in `function_score`),
passing a `null` reader disables query rewriting and for some use-cases, it is
simply not ok to rely on the current timestamp (eg. percolation). So this pull
request removes this method and instead requires that all call sites provide
these parameters explicitly.

* Add missing change
Today SearchContext expose the current context as a thread local which makes any kind of sane interface design very very hard. This PR removes the thread local entirely and instead passes the relevant context anywhere needed. This simplifies state management dramatically and will allow for a much leaner SearchContext interface down the road.
