This commit enableds strict settings validation on node startup. All settings
passed to elasticsearch either through system properties, yaml files or any other
way to pass settings must be registered and valid. Settings that are unknown ie. due to
typos or due to deprecation or removal will cause the node to NOT start up. Plugins
have to declare all their settings on the `SettingsModule#registerSetting` and settings for
plugins that are not installed must be removed.
This commit also removes the ability to specify the nodes name via `-Des.name` or just `name` in the
configuration files. The node name must be prefixed with the node prexif like `node.name: Boom`. Left over
usage of `name` will also cause startup to fail.
As a prerequisite for refactoring the whole PhraseSuggestionBuilder
to be able to be parsed and streamed from the coordinating node, the
DirectCandidateGenerator must implement Writeable, be able to parse
a new instance (fromXContent()) and later when transported to the
shard to generate a PhraseSuggestionContext.DirectCandidateGenerator.
Also adding equals/hashCode and tests and moving DirectCandidateGenerator
to its own DirectCandidateGeneratorBuilder class.
This commit removes and forbids the use of lowercase ells ('l') in long
literals because they are often hard to distinguish from the digit
representing one ('1').
Closes#16329
When there is an exception thrown during pipeline creation within
Rest calls (in put pipeline, and simulate) We now return a structured
error response to the user with details around which processor's
configuration is the cause of the issue, or which configuration property
is misconfigured, etc.
Now MasterNodeOperations, ReplicationAllShards, ReplicationSingleShard, BroadcastReplication and BroadcastByNode actions keep track of their parent tasks.
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.
This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.
Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.
Closes#16217
This commit method renames the ScriptEngineService interface methods
types, extensions, and sandboxed to getTypes, getExtensions, and
isSandboxed, respectively.
This commit converts the script mode settings to the new settings
infrastructure. This is a major refactoring of the handling of script
mode settings. This refactoring is necessary because these settings are
determined at runtime based on the registered script engines and the
registered script contexts.
Doc values can now only be enabled by setting `doc_values: true` in the
mappings. Removing this feature also means that we can now fail mapping updates
that try to disable doc values.
Parsing is currently very lenient, which has the bad side-effect that if you
have a typo and pass eg. `store: fasle` this will actually be interpreted as
`store: true`. Since mappings can't be changed after the fact, it is quite bad
if it happens on an index that already contains data.
Note that this does not cover all settings that accept a boolean, but since the
PR was quite hard to build and already covers some main settirgs like `store`
or `doc_values` this would already be a good incremental improvement.
This adds support for returning the size of an array
or an collection, in addition to access fields via
`array.0` you can specify `array.size` to get its size.
* Added a `content_type` option at compile time to decide how variable values are encoded. Possible values are `application/json` and `plain/text`. Defaults to `application/json`.
* Added support for variable placeholders to lookup values from specific slots in arrays/lists.
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

We have two similar tests with the same name, ContextAndHeaderTransportTests.
They shared lots of common code so I extracted much of it into
ActionRecordingPlugin, a plugin which records all action requests for later
inspection.
I also removed all the warnings from both tests. That made lang-mustache
compile cleanly without any custom -Xlint so I removed those. To remove
the warnings I had to add type parameters to ActionFilter which seemed
like a good idea anyway.
1. Gets guice out of the business of building ScoreFunctionParsers and
QueryParsers.
2. Moves QueryParser registration to SearchModule
3. Moves NamedWriteableRegistry construction out of guice and into Node and
TransportClient.
4. Moves shape registration into SearchModule so now all named writeable
registration is done in the SearchModule.
This is breaking for plugin authors. Instead of declaring new QueryParser
like:
```java
public void onModule(IndicesModule module) {
module.registerQueryParser(NewQueryParser.class);
}
```
you do it like:
```java
public void onModule(SearchModule module) {
module.registerQueryParser(NewQueryParser::new);
}
```
The QueryParser's argument no longer come from @Inject, now they come from
the declaration in the plugin. The above example is for a no-arg QueryParser.
Most of the QueryParsers in Elasticsearch are no-arg.
ScoreFunctionParsers have a similar but slightly different change. This:
```java
public void onModule(SearchModule module) {
module.registerFunctionScoreParser(NewFunctionScoreParser.class);
}
```
becomes
```java
public void onModule(SearchModule module) {
module.registerFunctionScoreParser(new NewFunctionScoreParser());
}
```
Since all known ScoreFunctionParsers have no arg constructors its simpler to
just build them at registration time rather than specify a supplier that is
used to build them later.
Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
the environment is now available through NodeModule#getNode#getEnvironment and can be retrieved during onModule(NodeModule), no need for this indirection anymore using the BiFunction
* Folded IngestModule into NodeModule
* Renamed IngestBootstrapper to IngestService
* Let NodeService construct IngestService and removed the Guice annotations
* Let IngestService implement Closable
