Shadow replicas can not be simply promoted to primary by updating boolean like normal shards. Instead the are reinitialized and shut down and rebuilt as primaries. Currently we also given them new allocation ids but that throws off the in-sync allocation ids management. This commit changes this behavior to keep the allocation id of the shard.
Closes#20650
In 2.x, the S3 repository accepted a `/` (forward slash) to start
the repositories.s3.base_path, and it used a different string splitting
method that removed the forward slash from the base path, so there
were no issues.
In 5.x, we removed this custom string splitting method in favor of
the JDK's string splitting method, which preserved the leading `/`.
The AWS SDK does not like the leading `/` in the key path after the
bucket name, and so it could not find any objects in the S3 repository.
This commit fixes the issue by removing the leading `/` if it exists
and adding a deprecation notice that leading `/` will not be supported
in the future in S3 repository's base_path.
This change adds a overloaded `XContentMapValues#filter` method that returns
a function enclosing the compiled automatons that can be reused across filter
calls. This for instance prevents compiling automatons over and over again when
hits are filtered or in the SourceFieldMapper for each document.
Closes#20839
Removes a non-existant file from the non-`// CONSOLE` list. If you
remove all the non-`// CONSOLE` snippets from a file it must be
removed from the whitelist for the build to pass. Removing the file
entirely counts as removing the snippets.

Some objects like maps, iterables or arrays of objects can self-reference themselves. This is mostly due to a bug in code but the XContentBuilder should be able to detect such situations and throws an IllegalArgumentException instead of building objects over and over until a stackoverflow occurs.

Settings updates are important to be able to help and administer a cluster in distress. We shouldn't block it due to circuit breakers. An extreme example is where we are actually trying to increase and unreasonable low setting for the circuit breaker itself.

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.

`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

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`.

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.

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.
