Previously, the engine would catch an out of memory error and would try
to handle the error (it would try to fail the engine, and then it would
swallow the out of memory error). Catching the out of memory errors was
removed in 3343ceeae44f3d28e3c1ba7861886848df74e390 so this code path is
not effectively dead. This commit removes this dead code from the
engine.

The payload option was introduced with the new completion
suggester implementation in v5, as a stop gap solution
to return additional metadata with suggestions.
Now we can return associated documents with suggestions
(#19536) through fetch phase using stored field (_source).
The additional fetch phase ensures that we only fetch
the _source for the global top-N suggestions instead of
fetching _source of top results for each shard.
The recent changes to the Histogram Aggregator introduced a bug where
an exception would not be thrown if the maxBound of the extended bounds
is less that the minBound. This change fixes that bug.
Closes#19833
PR #19715 made AllocationService less lenient, requiring ShardRouting instances that are passed to its applyStartedShards and
applyFailedShards methods to exist in the routing table. As primary shard failures also fail initializing replica shards,
concurrent replica shard failures that are treated in the same cluster state update might not reference existing replica entries
in the routing table anymore. To solve this, PR #19715 ordered the failures by first handling replica before
primary failures. There are other failures that influence more than one routing entry, however. When we have a failed shard entry
for both a relocation source and target, then, depending on the order, either one or the other might point to an out-dated shard
entry. As finding a good order is more difficult than applying the failures, this commit re-adds parts of the ShardRouting
re-resolve logic so that the applyFailedShards method can properly treat shard failure batches.
GeoDistance is implemented using a crazy enum that causes issues with the scripting modules. This commit moves all distance calculations to arcDistance and planeDistance static methods in GeoUtils. It also removes unnecessary distance helper methods from ScriptDocValues.GeoPoints.
This commit enables completion suggester to return documents
associated with suggestions. Now the document source is returned
with every suggestion, which respects source filtering options.
In case of suggest queries spanning more than one shard, the
suggest is executed in two phases, where the last phase fetches
the relevant documents from shards, implying executing suggest
requests against a single shard is more performant due to the
document fetch overhead when the suggest spans multiple shards.
The method requires pairs of fieldnames and property arguments and will fail if
the varargs input is an uneven number. We should check this and fail with an
appropriate IllegalArgumentException instead.

Elasticsearch doesn't have any automatic mechanism to share these
components between indexes. If any component is heavy enough to
warrant such sharing then it is the Pugin's responsibility to do
it in their {@link AnalysisProvider} implementation. We recommend
against doing this unless absolutely necessary because it can be
difficult to get the caching right given things like behavior
changes across versions.

Closes#19814
This commit cleans up indices in a snapshot repository when all
snapshots containing the index are all deleted. Previously, empty
indices folders would lay around after all snapshots containing
them were deleted.
Plugins provide NamedWriteables that are added to the
NamedWriteableRegistry. Those are added on Nodes already, the same mechanism is
added to the setup for TransportClient.
This commit updates Jackson to the 2.8.1 version, which is more strict when it comes to build objects. It also adds the snakeyaml dependency that was previously shaded in jackson libs.
It also closes#18076
Instead of being lenient in QueryParseContext#parseInnerQueryBuilder we check that the token where the parser stopped reading was END_OBJECT, and throw error otherwise. This is a best effort to verify that the parsers read a whole object rather than stepping out in the middle of it due to malformed queries.
Fuzzy Query, like many other queries, used to parse even when the query referred to multiple fields and the first one would win. We rather throw an exception now instead.
Also added test for short prefix query variant and modified the parsing code to consume the whole query object.

Also modified the parsing code to consume the whole query object.
