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
1000 script compilations per minute limit. This commit increases the
limit in integration tests to 2048.
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:
```

To how you can cavalierly mock all the numbers at once with this change:
```
// TESTRESPONSE[s/(?<=[" ])\d+(\.\d+)?/$body.$_path/]
```
A user reported uneven balancing of load on nodes handling search requests from Kibana which supplies a session ID in a routing preference. Each shardId was selecting the same node for a given session ID because one data node had all primaries and the other data node held all replicas after cluster startup.
This change counteracts the tendency to opt for the same node given the same user-supplied preference by incorporating shard ID in the hash of the preference key. This will help randomise node choices across shards.
Closes#24642
This commit adds comments to org.elasticsearch.Assertions that disables
IntelliJ from complaining about using assert with side-effects, and
using constant conditions there as the side-effect with a constant
condition is intentionally employed.
This commit removes an unused assertions enabled method in
ESTestCase. For future uses of such a method, use the field ENABLED in
org.elasticsearch.Assertions.
Today in the code base we have lots of ugly code blocks like:
boolean assertionsEnabled = false;
assert assertionsEnabled = true;
if (assertionsEnabled) {
// something
}
These are a nuisance. Instead, we can do this in exactly one place and
replace these blocks with
if (Assertions.ENABLED) {
// something
}
The cool thing here is that since this is a static final field, the JIT
can optimize away the check at runtime if assertions are disabled.

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.

After releasing 5.3.2, the 5.3.3 version constant was created. However,
this causes issues for the rolling upgrade tests, which expect to have
all older versions artifacts published and no point releases created off
of the older versions (older meaning more than one version behind the
current version). This commit removes the 5.3.3 version constant,
assuming we will not need it anywhere.
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.
This commit fixes the RangeFieldMapper and RangeQueryBuilder to pass the correct relation to the RangeQuery when performing a range query over range fields.
Currently a `delete document` request against a non-existing index actually **creates** this index.
With this change the `delete document` no longer creates the previously non-existing index and throws an `index_not_found` exception instead.
However as discussed in https://github.com/elastic/elasticsearch/pull/15451#issuecomment-165772026, if an external version is explicitly used, the current behavior is preserved and the index is still created and the document is marked for deletion.
Fixes#15425
This commit is a simple cleanup to remove an unnecessary extra method on
ScriptService which was only used in 3 places. There is now only one
search method.
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.
This commit removes a convenience method from index shard that is used
at exactly one call site. This method is used to callback a listener
when an operation is on too old of a primary term. Since it is only used
at one call site, we simply inline the method.
Today a replica learns of a new primary term via a cluster state update
and there is not a clean transition between the older primary term and
the newer primary term. This commit modifies this situation so that:
- a replica shard learns of a new primary term via replication
operations executed under the mandate of the new primary
- when a replica shard learns of a new primary term, it blocks
operations on older terms from reaching the engine, with a clear
transition point between the operations on the older term and the
operations on the newer term
This work paves the way for a primary/replica sync on primary
promotion. Future work will also ensure a clean transition point on a
promoted primary, and prepare a replica shard for a sync with the
promoted primary.

When Elasticsearch dies during a standalone REST test we might leave a
dirty PID file laying around. We tried to log about this, but the log
messages contained references to undefined variables so we simply died
instead of providing a helpful message to run clean. This commit
addresses this issue.
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.

Today when we get a metadata snapshot from the index shard we ensure
that if there is no engine started on the shard that we lock the index
writer before we go and fetch the store metadata. Yet, if we concurrently
recover that shard, recovery finalization might fail since it can't acquire
the IW lock on the directory. This is mainly due to the wrong order of aquiring
the IW lock and the metadata lock. Fetching store metadata without a started engine
should block on the metadata lock in Store.java but since IndexShard locks the writer
first we get into a failed recovery dance especially in test. In production
this is less of an issue since we rarely get into this siutation if at all.
Closes#24481
The method should rather advance one token and only then require a START_OBJECT as the current token. This allows to parse given a parser that's at the beginning of the response, where the initial/current token is null.
Now the Java High Level Rest Client has tests to parse all aggregations,
this test is not needed anymore. We have better tests like
AggregationsTests and sub classes of InternalAggregationTestCase.
