ElasticsearchException is used in various response objects like IndexResponse, DeleteResponse or BulkItemResponse.Failure. It would be helpful to the High Level Rest Client to be able to parse these exceptions back.
This commit adds the fromXContent() method to the ElasticsearchException object. This method does not return the original (wrapped or unwrapped) exception but always returns a ElasticsearchException that serves as a simple POJO for all types of exceptions. The parsed ElasticsearchException's message will be composed of the original exception type (ex: illegal_argument_exception) concatenated with the original reason to help users/clients to known and handle the error.
PR #22049 changed the node update logic to never remove nodes from the cluster state when the cluster state is not published. This led to an issue electing a master (#22120) based on nodes with same transport address (but different node id) as previous nodes. The joining nodes should take precedence over conflicting ones. Note that this only applies to the action of becoming master. If a master is established and a node joins an existing master, it will be rejected if there is another node with same transport address.
For minDocCount=0 the numeric terms aggregator should also check the includes/excludes when buckets with empty count are added to the result.
This change fixes this bug and adds a test for it.
Fixes#22140
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
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
Today we write 0x00 or 0x01 for false or true when serializing a boolean
(and 0x02 for null when serializing an optional boolean) but we
deserialize any non-zero byte to true (except when deserializing an
optional boolean in which case we deserialize 0x02 to null, 0x01 to
true, and any other non-zero byte to false). This too easily allows
corruption into the stream. Instead, we should mark the stream as
corrupted and stop deserializing. This catches when we try to
deserialize something as a boolean that is not a boolean.

This commit enables CLI commands to be closeable and installs a runtime
shutdown hook to ensure that if the JVM shuts down (as opposed to
aborting) the close method is called.
It is not enough to wrap uses of commands in main methods in
try-with-resources blocks as these will not run if, say, the virtual
machine is terminated in response to SIGINT, or system shutdown event.

Grok was originally ignoring potential matches to named-capture groups
larger than one. For example, If you had two patterns containing the
same named field, but only the second pattern matched, it would fail to
pick this up.
This PR fixes this by exploring all potential places where a
named-capture was used and chooses the first one that matched.
Fixes#22117.
This commit fixes a for loop that reverses the order of shard stats
coming off the wire, and is really hard to read anyway (with the
post-increment in the loop initializer).

Today we rely on the version that the API user passes in together with the DiscoveryNode. This commit introduces a low level handshake where nodes exchange their version to be used with the transport protocol that is executed every time a connection to a node is established. This, on the one hand allows to change the wire protocol based on the version we are talking to even without a full cluster restart. Today we would need to carry on a BWC layer across major versions but with a handshake we can rely on the fact that the latest version of the previous minor executes a handshake and uses the latest protocol version across all communication with the N+1 version nodes.
This change is yet fully backwards compatible, a followup PR will remove the BWC in 6.0 once this has been back-ported to the 5.x branch
Starts to centralize creation of the `XContentParser` in
`protected final` methods on `ESTestCase`. The idea is to enable
adding `NamedXContentRegistry` relatively easily by giving tests
a single place they can override to define the
`NamedXContentRegistry`. Since `NamedXContentRegistry` doesn't
exist yet neither does the override point.
This doesn't attempt to migrate all the tests to calling the
new methods to build the parsers. I wanted to make this so we
could review the concept and then I'll merge a followup to
migrate the tests.
Not only was StringJoiner unused, it's also a class only available in java 1.8, which is a problem given that the REST client has minimum java required set to 1.7
Add checks to RankEvalSpec to safe guard against missing parameters.
Fail early in case no metric is supplied, no rated requests are supplied or the search source builder is missing but no template is supplied neither.
Add stricter checks around rank eval request parsing: Fail if in a rated request we see both, a verbatim request as well as request
template parameters.

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.
When using dynamic templates, ES will now throw an exception if a
`match_mapping_type` is used that doesn't correspond to an actual type.

Plugins also have the need to provide better OOTB experience by configuring
defaults unless the plugin is used in _production_ mode. This change exposes
the bootstrap check infrastructure as part of the plugin API to allow plugins
to specify / install their own bootstrap checks if necessary.
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.
The warnings get printed out in a single line e.g. WARNING: request [DELETE http://localhost:9200/index/type/_api] returned 3 warnings:[this is warning number 0],[this is warning number 1],[this is warning number 2]
When we decided to deprecate and remove fuzzy query in #15760, we didn't realize we would take away the possibililty for uses to use a fuzzy query as part of a span query, which is not possible using match query. This means we have to go back and un-deprecate fuzzy query, which will not be removed.
Closes#15760
Queries must be rewritten before the query phase executes otherwise non-executable queries like `wrapper` query or `terms` will fail or queries that require resources like script service can't access these service unless rewritten.

This change allows specifying alias/wildcard expression in indices_boost.
And added another format for specifying indices_boost. It accepts array of index name and boost pair.
If an index is included in multiple aliases/wildcard expressions, the first match will be used.
With new format, old format is marked as deprecated.
Closes#4756
`include` / `exclude` in terms / sig-terms aggs seems completely broken
and massively untested. This commit makes the TermsTests pass again that
randomly use `include` / `exclude`. This class must be tested individually
and we need real integ tests that use xcontent that use this feature.
An earlier commit removed BWC for pre-5.0 snapshots, which also meant removing the capability to load pre-5.0 snapshots. In 6.0, such snapshots are now
invisible and must be treated by the BWC tests in that way.
URLBlobContainer can in certain situations throw a FileNotFoundException. To fulfill the contract of the readBlob method it should throw a NoSuchFileException instead when the given blob cannot be found.
