(#23437)
For the response parsing we want to be lenient when it comes to parsing
new xContent fields. In order to ensure this in our testing, this change
adds a utility method to XContentTestUtils that takes xContent bytes
representation as input and recursively a random field on each object
level.
Sometimes we also want to exclude a whole subtree from this treatment
(e.g. skipping "_source"), other times an element (e.g. "fields", "highlight"
in SearchHit) can have arbitraryly named objects. Those cases can be
specified as exceptions.

Splits TranslogRecoveryPerformer into three parts:
- the translog operation to engine operation converter
- the operation perfomer (that indexes the operation into the engine)
- the translog statistics (for which there is already RecoveryState.Translog)
This makes it possible for peer recovery to use the same IndexShard interface as bulk shard requests (i.e. Engine operations instead of Translog operations). It also pushes the "fail on bad mapping" logic outside of IndexShard. Future pull requests could unify the BulkShard and peer recovery path even more.

This change moves the parent_id query to the parent-join module and handles the case when only the parent-join field can be declared on an index (index with single type on).
If single type is off it uses the legacy parent join field mapper and switch to the new one otherwise (default in 6).

Both gradle and java code attempt to infer the type of a each
Version constant in Version.java. It is super important that
they infer that each constant has the same type. If they disagree
we might accidentally not be testing backwards compatibility for
some version.
This adds a test to make sure that they agree, modulo known and
accepted differences (mostly around alphas). It also changes the
minimum wire compatible version from the released 5.4.0 to the
unreleased 5.5.0 as that lines up with the gradle logic.
Relates to #24798
Note that the gradle and java version logic doesn't actually match so
this contains a hack to make it *look* like it matches. Since this is a
start, I'm merging it and going to work on some followups to make the
logic actually match.....

This commit creates TemplateScript and associated classes so that
templates no longer need a special ScriptService.compileTemplate method.
The execute() method is equivalent to the old run() method.

Previously, when allocating bytes for a BigArray, the array was created
(or attempted to be created) and only then would the array be checked
for the amount of RAM used to see if the circuit breaker should trip.
This is problematic because for very large arrays, if creating or
resizing the array, it is possible to attempt to create/resize and get
an OOM error before the circuit breaker trips, because the allocation
happens before checking with the circuit breaker.
This commit ensures that the circuit breaker is checked before all big
array allocations (note, this does not effect the array allocations that
are less than 16kb which use the [Type]ArrayWrapper classes found in
BigArrays.java). If such an allocation or resizing would cause the
circuit breaker to trip, then the breaker trips before attempting to
allocate and potentially running into an OOM error from the JVM.
Closes #24790

After every REST test we wait for the list of pending cluster tasks
to empty before moving on to the next task. If the list doesn't
empty in 10 second we fail the test. This improves the error message
when we fail the test to include the list of running tasks.

For comparing actual and parsed object equality for the response parsing we
currently rely on comparing the original xContent and the output of the parsed
object. Currently we only have cryptic error messages if this comparison fails
which are hard to read also because we recursively compare lists and maps of
the xContent structures we compare.
This commits leverages the existing NotEqualMessageBuilder for providing error
messages that are more detailed and useful for debugging if an error occurs.

script contexts (#24974)
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.

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

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 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.

With #24779 in place, we can now guaranteed that a single translog generation file will never have a sequence number conflict that needs to be resolved by looking at primary terms. These conflicts can a occur when a replica contains an operation which isn't part of the history of a newly promoted primary. That primary can then assign a different operation to the same slot and replicate it to the replica.
PS. Knowing that each generation file is conflict free will simplifying repairing these conflicts when we read from the translog.
PPS. This PR also fixes some bugs in the piping of primary terms in the bulk shard action. These bugs are a result of the legacy of IndexRequest/DeleteRequest being a ReplicationRequest. We need to change that as a follow up.

This commit cleans up tests which currently use custom script engine
implementations, converting them to use a MockScriptEngine with script
functions provided by the tests. It also creates a common set of metric
scripts which were copied across a couple metric agg tests.

Large test suites with unfortunate seed choices can easily exceed the

Adds a "magic" key to the yaml testing stash mostly for use with
documentation tests. When unstashing an object, `$_path` is the
path into the current position in the object you are unstashing.
This means that in docs tests you can use
`// TESTRESPONSEs/somevalue/$body.${_path}/` to mean "replace
`somevalue` with whatever is the response in the same position."
Compare how you must carefully mock out all the numbers in the profile
response without this change:

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.

Given that both InternalAggregation and ParsedAggregation have this method, it makes sense to move it to the interface they both implement.

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.

where possible (#24753)
This PR revolves around places in the code where introducing a StringBuilder might make the construction
of a String easier to follow and also, maybe avoid a case where the compiler's very safe way of introducing
StringBuilder instead of String might not always be optimal for performance.

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).
