The cache relies on the equals() method so we just need to make sure script
queries can never be equals, even to themselves in the case that a weight
is used to produce a Scorer on the same segment multiple times.
Closes#20763
`TcpTransport.ScheduledPing` doesn't handle rejected exceutions gracefully
if the executor is shutting down. This change adds correct exception handling
if we try to schedule another ping while the node is shutting down.
Update scripts might want to update the documents `_timestamp` but need a notion of `now()`.
Painless doesn't support any notion of now() since it would make scripts non-pure functions. Yet,
in the update case this is a valid value and we can pass it with the context together to allow the
script to record the timestamp the document was updated.

SynonymQuery was ignored by the FastVectorHighlighter.
This change adds the support for SynonymQuery in the FVH.
Although this change should be implemented in Lucene directly which is why https://issues.apache.org/jira/browse/LUCENE-7484 has been opened.
In the meantime this PR handles the issue on ES side and could be removed when LUCENE-7484 gets merged.
Fixes#20781
* Replace org.elasticsearch.common.lucene.search.MatchNoDocsQuery with its Lucene version (org.apache.lucene.search.MatchNoDocsQuery)
This change removes the ES version of the match no docs query and replaces it with the Lucene version.

* Add missing change
Today we throw an assertion error if we release an AbstractArray more than once.
Yet, it's recommended to implement close methods such that they can be invoked
more than once. Guaranteed single release calls are hard to implement and some
situations might not be tested causing for instance `CircuitBreaker` to operate on
corrupted memory stats.
With this commit we separate benchmark parameters with pipe symbols
instead of commas as JMH has a special formatting logic for comma-separated
string which messes up the JSON output of microbenchmarks.
* Fix match_phrase_prefix query with single term on _all field
This change fixes the match_phrase_prefix query when a single term is queried on the _all field.
It builds a prefix query instead of an AllTermQuery which would not match any prefix.
Fixes#20470
* Add missing change
Mappings treat dots in field names as sub objects, for instance
```
{
"a.b": "c"
}
```
generates the same dynamic mappings as
```
{
"a": {
"b": "c"
}
}
```
Source filtering should be consistent with this behaviour so that an include
list containing `a` should include fields whose name is `a.b`.
To make this change easier, source filtering was refactored to use automata.
The ability to treat dots in field names as sub objects is provided by the
`makeMatchDotsInFieldNames` method of `XContentMapValues`.
Closes#20719
Instead provide services where they are needed. The class worked
well as a temporary measure to easy removal of guice from the index
level but now we can remove it entirely.

This commit upgrades the Log4j 2 dependency to version 2.7 and removes
some hacks that we had in place to work around bugs in Log4j 2 version
2.6.2.

UpdateHelper, MetaDataIndexUpgradeService, and some recovery
stuff.
Move ClusterSettings to nullable ctor parameter of TransportService
so it isn't forgotten.
The `QueryShardContext.failIfFrozen()` and `QueryShardContext.freezeContext()`
methods should be final so that overriding/bypassing the freezing of
`QueryShardContext` is not possible. This is important so that we can
trust when the `QueryShardContext` says a request is cacheable.
This change also makes the methods that call `QueryShardContext.failIfFrozen()`
`final` so they cannot be overridden to bypass setting the request as not
cacheable.
Elasticsearch 1.x used to implicitly round up upper bounds of queries when they
were inclusive so that eg. `[2016-09-18 TO 2016-09-20]` would actually run
`[2016-09-18T00:00:00.000Z TO 2016-09-20T23:59:59.999Z]` and include dates like
`2016-09-20T15:32:44`. This behaviour was lost in the cleanups of #8889.
Closes#20579
The shards preference on a search request enables specifying a list of
shards to hit, and then a secondary preference (e.g., "_primary") can be
added. Today, the separator between the shards list and the secondary
preference is ';'. Unfortunately, this is also a valid separtor for URL
query parameters. This means that a preference like "_shards:0;_primary"
will be parsed into two URL parameters: "_shards:0" and "_primary". With
the recent change to strict URL parsing, the second parameter will be
rejected, "_primary" is not a valid URL parameter on a search
request. This means that this feature has never worked (unless the ';'
is escaped, but no one does that because our docs do not that, and there
was no indication from Elasticsearch that this did not work). This
commit changes the separator to '|'.

This change proposes the removal of all non-tcp transport implementations. The
mock transport can be used by default to run tests instead of local transport that has
roughly the same performance compared to TCP or at least not noticeably slower.
This is a master only change, deprecation notice in 5.x will be committed as a
separate change.
Previous to this change the DateMathParser accepted a Callable<Long> to use for accessing the now value. The implementations of this callable would fall back on System.currentTimeMillis() if there was no context object provided. This is no longer necessary for two reasons:
We should not fall back to System.currentTimeMillis() as a context should always be provided. This ensures consistency between shards for the now value in all cases
We should use a LongSupplier rather than requiring an implementation of Callable. This means that we can just pass in context::noInMillis for this parameter and not have not implement anything.
Previously, this doc was using a field called "content". This is
confusing, especially when the doc starts talking about the content of
the content field. This change makes the field name "comment" which
is less ambiguous and also changes some related field names in the doc
to make a consistent example theme of editing docs around blog posts.
This commit improves the shard decision container class in the following
ways:
1. Renames UnassignedShardDecision to ShardAllocationDecision, so that
the class can be used for general shard decisions, not just unassigned
shard decisions.
2. Changes ShardAllocationDecision to have the final decision as a Type
instead of a Decision, because all the information needed from the final
decision is contained in `Type`.
3. Uses cached instances of ShardAllocationDecision for NO and THROTTLE
decisions when no explanation is needed (which is the common case when
executing reroute's as opposed to using the explain API).
