This commit modifes the EsThreadPoolTestCase#info helper method to
return null when info for the thread pool can not be found. This really
should only happen for the "same" thread pool, and so we also assert
that we only get to a place where there is no info if the thread pool
that info was requested for is in fact the "same" thread pool. Not
returning null here and instead throwing an exception would fail tests
that tried to lookup info on the "same" thread pool.
Today we use a sliced lock strategy for acquiring locks to prevent
concurrent updates to the same document. The number of sliced locks is
computed as a linear function of the number of logical
processors. Unfortunately, the probability of a collision against a
sliced lock is prone to the birthday problem and grows faster than
expected. In fact, the mathematics works out such that for a fixed
target probability of collision, the number of lock slices should grow
like the square of the number of logical processors. This is
less-than-ideal, and we can do better anyway. This commit introduces a
strategy for avoiding lock contention within the internal
engine. Ideally, we would only have lock contention if there were
concurrent updates to the same document. We can get close to this ideal
world by associating a lock with the ID of each document. This
association can be held in a concurrent hash map. Now, the JDK
ConcurrentHashMap also uses a sliced lock internally, but it has several
strategies for avoiding taking the locks and these locks are only held
for a very short period of time. This implementation associates a
reference count with the lock that is associated with a document ID and
automatically removes the document ID from the concurrent hash map when
the reference count reaches zero.

Fix a limitation that prevent from hierarchical inner hits be defined in query dsl.
Removed the nested_path, parent_child_type and query options from inner hits dsl. These options are only set by ES
upon parsing the has_child, has_parent and nested queries are using their respective query builders.
These options are still used internally, when these options are set a new private copy is created based on the
provided InnerHitBuilder and configuring either nested_path or parent_child_type and the inner query of the query builder
being used.
Closes#11118
Previously like in other geo related query parsers we were using
a combination of two booleans for coerce and ignore_malformed
which was error prone and not very clear.
Switched to using GeoValidationMethod instead as we already do
e.g. in GeoBoundingBoxQueryBuilder.
Left support for both, coerce and ignore_malformed in the parser
but deprecated the two in favour of validation method.
Introduced the same deprecation in geo bounding box query builder.
While returning no hits on fields that are not mapped may be fine, it is not
for fields that are mapped but not indexed (`index:false`). We should fail the
query in that case rather than returning no hits.
Switch something from an explicit toString to Strings.toString which
is the same thing but with more code reuse.
Also renamed a constant to be CONSTANT_CASE.
ObjectParser makes parsing XContent 95% easier. No more nested loops.
No more forgetting to use ParseField. Consistent handling for arrays.
Awesome. But ObjectParser doesn't support building things objects whose
constructor arguments are mixed in with the rest of its properties.
Enter ConstructingObjectParser! ConstructingObjectParser queues up
fields until all of the constructor arguments have been parsed and
then sets them on the target object.
Closes#17352
* Add isSearchable and isAggregatable (collapsed to true if any of the instances of that field are searchable or aggregatable).
* Accept wildcards in field names.
* Add a section named conflicts for fields with the same name but with incompatible types (instead of throwing an exception).
This commit fixes a test bug in the scaling thread pool idle
test. Namely, a random thread pool is chosen which could have a min pool
size of one or four but the while loop was acting as if the min pool
size was four (this is due to the test having been initially written for
only the generic thread pool).
Additionally, a latch is added between the test thread and the work
tasks to reduce the chance of a race condition between the test thread
and last few tasks.
