* Introduce ParentJoinFieldMapper, a field mapper that creates parent/child relation within documents of the same index
This change adds a new field mapper named ParentJoinFieldMapper. This mapper is a replacement for the ParentFieldMapper but instead of using the types in the mapping
it uses an internal field to materialize parent/child relation within a single index.
This change also adds a fetch sub phase that automatically retrieves the join name (parent or child name) and the parent id for child documents in the response hit fields.
The compatibility with `has_parent`, `has_child` queries and `children` agg will be added in a follow up.

ScriptContexts currently understand a FactoryType that can produce
instances of the script InstanceType. However, for search scripts, this
does not work as we have the concept of LeafSearchScript that is created
per lucene segment. This commit effectively renames the existing
SearchScript class into SearchScript.LeafFactory, which is a new,
optional, class that can be defined within a ScriptContext.
LeafSearchScript is effectively renamed back into SearchScript. This
change allows the model of stateless factory -> stateful factory ->
script instance to continue, but in a generic way that any script
context may take advantage of.

DateProcessor's DateFormat UNIX format parser resulted in
a floating point rounding error when parsing certain stringed
epoch times. Now Double.parseDouble is used, preserving the
intented input.
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.
Removes the need for the `_UNRELEASED` suffix on versions by detecting if a version should be unreleased or not based on the versions around it. This should make it simpler to automate the task of adding a new version label.
This commit renames the concept of the "compiled type" to a "factory
type", along with all implementations of this class to be named Factory.
This brings it inline with the classes purpose.
This commit adds collection of all contexts to the parameters of
getScriptEngine. This will allow script engines like painless to
precache extra information about the contexts.
This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
This commit changes the compile method of ScriptEngine to be generic in
the same way it is on ScriptService. This moves the shim of handling the
two existing context classes into each script engine, so that each
engine can be worked on independently to convert to real handling of
contexts.
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.
Since groovy was removed, we no longer have any ScriptEngines with
resources to release. We may want to keep the option open for a script
engine to close resources, but this would not be common. This commit
adds a default implementation to ScriptEngine for `close()` to reduce
the boiler plate that must be added for a ScriptEngine implementation.
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 moves the handling of nested and parent/child inner hits to specialized classes that can be defined outside of ES core.
InnerHitBuilderContext is now used by the parent query (nested or hasChild, ...) to build the sub context from the InnerHitBuilder definition.
BWC is also ensured so that nodes in previous versions can still send/receive inner hits to/from this version.

As we work towards contexts implying the return type of compilation, we
first need ScriptContext to not be an enum. This commit removes the
Standard enum and Plugin subclass of ScriptContext.
ScriptEngine implementations have an overridable method to indicate they
are safe to use as inline scripts. Since groovy was removed fro 6.0,
there are no longer any implementations which used the default false
value. Furthermore, the value was not actually read anywhere. This
commit removes the method. The ScriptEngineRegistry was also no longer
necessary as it only was used to build a map from language to engine.
Allows plugins to register pre-configured tokenizers. Much
of the decisions are the same as those in #24223, #24572,
and #24223. This only migrates the lowercase tokenizer but
I figure that is a good start because it proves out the features.
This change removes the field data specialization needed for the parent field and replaces it with
a simple DocValuesIndexFieldData. The underlying global ordinals are retrieved via a new function called
IndexOrdinalsFieldData#getOrdinalMap.
The children aggregation is also modified to use a simple WithOrdinals value source rather than the deleted WithOrdinals.Parent.

Shared settings were added intially to allow the few common settings
names across aws plugins. However, in 6.0 these settings have been
removed. The last use was in netty, but since 6.0 also has the netty 3
modules removed, there is no longer a need for the shared property. This
commit removes the shared setting property.
Approaching the release of 6.0 we need to sort out the usage of
`Version#minimumCompatibilityVersion` which was still set to 5.0.0.
Now this change moves it to the latest released version of 5.x (5.4 at this point)
to ensure we are compatible with the latest minor of the previous major. This change
also removes all the `_UNRELEASED` from the versions that where released and drops versions
that were never released and are not expected to be released (bugfixes in minors that are not
the latest in the previous major).
We've switched to supporting only `yml` files but anyone who didn't
notice will commit a `yaml` file which won't be executed
which is bad because it is easy not to notice. The test to catch this is
simple enough that I think it is worth adding just to warn folks about
their mistake.
These tests are broken because I added them with the `yml` extension
and didn't realize that we weren't running tests with that extension
until we merged #24659. I used that extension in anticipation of #24659
but didn't verify that the tests were actually running. Ooops!
Closes#24734
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.
Moves the remaining preconfigured token figured into the analysis-common module. There were a couple of tests in core that depended on the pre-configured token filters so I had to touch them:
* `GetTermVectorsCheckDocFreqIT` depended on `type_as_payload` but didn't do anything important with it. I dropped the dependency. Then I moved the test to a single node test case because we're trying to cut down on the number of `ESIntegTestCase` subclasses.
* `AbstractTermVectorsTestCase` and its subclasses depended on `type_as_payload`. I dropped their usage of the token filter and added an integration test for the termvectors API that uses `type_as_payload` to the `analysis-common` module.
* `AnalysisModuleTests` expected a few pre-configured token filtes be registered by default. They aren't any more so I dropped this assertion. We assert that the `CommonAnalysisPlugin` registers these pre-built token filters in `CommonAnalysisFactoryTests`
* `SearchQueryIT` and `SuggestSearchIT` had tests that depended on the specific behavior of the token filters so I moved the tests to integration tests in `analysis-common`.
Today when an index is `read-only` the index is also blocked from
being deleted which sometimes is undesired since in-order to make
changes to a cluster indices must be deleted to free up space. This is
a likely scenario in a hosted environment when disk-space is limited to switch
indices read-only but allow deletions to free up space.
Range queries with now based date ranges were previously not allowed,
but since #23921 these queries were allowed. This change should really
fix range queries with now based date ranges.
Template script engines (mustache, the only one) currently return a
BytesReference that users must know is utf8 encoded. This commit
modifies all callers and mustache to have the template engine return
String. This is much simpler, and does not require decoding in order to
use (for example, in ingest).
Netty removed a logging guarded we added to prevent a scary logging
message. We added a hack to work around this. They've added the guard
back, so we can remove the hack now.
