Sometimes it's useful / needed to use unreleased Version constants but we should not add those to the Version.java class for several reasons ie. BWC tests and assertions along those lines. Yet, it's not really obvious how to do that so I added some comments and a simple test for this.
There was an issue with using fuzziness parameter in multi_match query that has
been reported in #18710 and was fixed in Lucene 6.2 that is now used on master.
In order to verify that fix and close the original issue this PR adds the test
from that issue as an integration test.
today we might release a bytes array more than once if the send listener
throws an exception but already has released the array. Yet, this is already fixed
in the BytesArray class we use in production to ensure 3rd party users don't release
twice but our mocks still enforce it.
The snapshot restore state tracks information about shards being restored from a snapshot in the cluster state. For example it records if a shard has been successfully restored or if restoring it was not possible due to a corruption of the snapshot. Recording these events is usually based on changes to the shard routing table, i.e., when a shard is started after a successful restore or failed after an unsuccessful one. As of now, there were two communication channels to transmit recovery failure / success to update the routing table and the restore state. This lead to issues where a shard was failed but the restore state was not updated due to connection issues between data and master node. In some rare situations, this lead to an issue where the restore state could not be properly cleaned up anymore by the master, making it impossible to start new restore operations. The following change updates routing table and restore state in the same cluster state update so that both always stay in sync. It also eliminates the extra communication channel for restore operations and uses standard cluster state listener mechanism to update restore listener upon successful
completion of a snapshot.
* Fixed writeable name from range to geo_distance
* Added testGeoDistanceAggregation
* Added asserts for correct result in testGeoDistanceAggregation
* Setup mapping on test index.
When refactoring DirectCandidateGeneratorBuilder recently, the
ConstructingObjectParser that we have today was not available. Instead we used
some workaround, but it is better to remove this now and use
ConstructingObjectParser instead.

Uses the new sorting (#20658) in the `_cat` API to support all use
cases natively. We can still resort to piping things through `sort`
if we need to, but we don't have to for basic stuff like sorting!
* Adding built-in sorting capability to _cat apis.
Closes#16975
* addressing pr comments
* changing value types back to original implementation and fixing cosmetic issues
* Changing compareTo, hashCode of value types to a better implementation
* Changed value compareTos to use Double.compare instead of if statements + fixed some failed unit tests
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.
Related to #18160
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.
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.
