* Fixes#24259
Corrects the ScriptedMetricAggregator so that the script can have
access to scores during the map stage.
* Restored original tests. Added seperate test.
As requested, I've restored the non-score dependant tests, and added the
score dependent metric as a seperate test.
Netty uses the number of processors for sizing various resources (e.g.,
thread pools, buffer pools, etc.). However, it uses the runtime number
of available processors which might not match the configured number of
processors as set in Elasticsearch to limit the number of threads (for
example, in Docker containers). A new feature was added to Netty that
enables configuring the number of processors Netty should see for sizing
this various resources. This commit takes advantage of this feature to
set this number of available processors to be equal to the configured
number of processors set in Elasticsearch.

* Fix wrong delegation to constructors when compiling lambdas with method references to ctors. Also remove the get$lambda factory.
* Cleanup code and remove unneeded transformations between binary and internal class names (uses ASM Type class instead)
* Cleanup Exception handling
* Simplification by moving the type adaption to the outside
* Remove STATIC access flag from our Lambda class (not required and also officially not allowed)
* Move the lambda counter to the classloader, so we have a per-script lambda ID
* Change Codesource of generated lambdas to be consistent
The _cat/shards docs asserted that one of the columns looked like
a propery byte size but used a regex like `\d+\.\d+.*` which doesn't
match `0b` which is a possible value. Instead this uses
`\d(\.\d+)?[kmg]?b`.
The response is attempting to illustrate the sync_id marker, but in
the test the index is too "fresh" to have a sync marker. So the test
needs to execute a sync flush behind the scenes so that the marker
is present
In #22267, we introduced the notion of incompatible snapshots in a
repository, and they were stored in a root-level blob named
`incompatible-snapshots`. If there were no incompatible snapshots in
the repository, then there was no `incompatible-snapshots` blob.
However, this causes a problem for some cloud-based repositories,
because if the blob does not exist, the cloud-based repositories may
attempt to keep retrying the read of a non-existent blob with
expontential backoff until giving up. This causes performance issues
(and potential timeouts) on snapshot operations because getting the
`incompatible-snapshots` is part of getting the repository data (see
RepositoryData#getRepositoryData()).
This commit fixes the issue by creating an empty
`incompatible-snapshots` blob in the repository if one does not exist.
This method has to do with how the transport action may or may not resolve wildcards expressions to aliases names. It is only needed in TransportIndicesAliasesAction and for this reason it should be a private method in it rather than part of a request class which is also part of the Java API and later in the high level REST client.
This commit cleans up some cases where a list or map was being
constructed, and then an existing collection was copied into the new
collection. The clean is to instead use an appropriate constructor to
directly copy the existing collection in during collection
construction. The advantage of this is that the new collection is sized
appropriately.

This commit removes a few duplicates from the list of checkstyle
suppressions that accumulated while auto-generating the list of
suppressions based on the files that currently exceed the 140-column
limit.
The list of checkstyle suppressions was auto-generated based on the list
of files that currently violate the 140-column limit. An errant entry
was committed that did no harm, but this commit removes it.
We are back to having a 140-column limit. While at some point we will
apply auto-formatting tools to the code base, that is a down-the-road
thing and adjusting the suppressions now shaves minutes off the build
time.

With #24236, the master now uses the pending queue when publishing to itself. This means that a cluster state update is put into the pending queue,
then sent to the ClusterApplierService to be applied. After it has been applied, it is marked as processed and removed from the pending queue.
ensureGreen is implemented as a cluster health action that waits on certain conditions, which will lead to a cluster state update task to be submitted
on the master. When this task gets to run and the conditions are not satisfied yet, it register a cluster state observer. This observer is registered
on the ClusterApplierService and waits on cluster state change events. ClusterApplierService first notifies the observer and then the discovery
layer. This means that there is a small time frame where ensureGreen can complete and call the node stats to find the pending queue still containing
the last cluster state update.
Closes#24388
Failure detection should only be updated in ZenDiscovery after the current state has been updated to prevent a race condition
with handleLeaveRequest and handleNodeFailure as those check the current state to determine whether the failure is to be handled by this node.
Open/close index API when executed providing an index expressions that matched no indices, threw an error even when allow_no_indices was set to true. The APIs should rather honour the option and behave as a no-op in that case.
Closes#24031
Currently we don't write the count value to the geo_centroid aggregation rest response,
but it is provided via the java api and the count() method in the GeoCentroid interface.
We should add this parameter to the rest output and also provide it via the getProperty()
method.
Eclipse doesn't allow extra semicolons after an import statement:
```
import foo.Bar;; // <-- syntax error!
```
Here is the Eclipse bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=425140
which the Eclipse folks closed as "the spec doesn't allow these
semicolons so why should we?" Which is fair. Here is the bug
against javac for allowing them:
https://bugs.openjdk.java.net/browse/JDK-8027682
which hasn't been touched since 2013 without explanation. There
is, however, a rather educations mailing list thread:
http://mail.openjdk.java.net/pipermail/compiler-dev/2013-August/006956.html
which contains gems like, "In general, it is better/simpler to
change javac to conform to the spec. (Except when it is not.)"
I suspect the reason this hasn't been fixed is:
```
FWIW, if we change javac such that the set of programs accepted by javac
is changed, we have an process (currently Oracle internal) to get
approval for such a change. So, we would not simply change javac on a
whim to meet the spec; we would at least have other eyes looking at the
behavioral change to determine if it is "acceptable".
```

The alias parameter was documented as a list in our rest-spec, yet only the first value out of a list was getting read and processed. This commit adds support for multiple aliases to _cat/aliases
Closes#23661
The version on an update request is a syntactic sugar
for get of a specific version, doc merge and a version
index. This changes it to reject requests with both
upsert and a version.
If the upsert index request is versioned, we also
reject the op.
The previous commit (35f78d098a) introduced an assertion in ZenDiscovery that was overly restrictive - it could trip when a cluster state that was
successfully published would not be applied locally because a master with a better cluster state came along in the meantime.
Separates cluster state publishing from applying cluster states:
- ClusterService is split into two classes MasterService and ClusterApplierService. MasterService has the responsibility to calculate cluster state updates for actions that want to change the cluster state (create index, update shard routing table, etc.). ClusterApplierService has the responsibility to apply cluster states that have been successfully published and invokes the cluster state appliers and listeners.
- ClusterApplierService keeps track of the last applied state, but MasterService is stateless and uses the last cluster state that is provided by the discovery module to calculate the next prospective state. The ClusterService class is still kept around, which now just delegates actions to ClusterApplierService and MasterService.
- The discovery implementation is now responsible for managing the last cluster state that is used by the consensus layer and the master service. It also exposes the initial cluster state which is used by the ClusterApplierService. The discovery implementation is also responsible for adding the right cluster-level blocks to the initial state.
- NoneDiscovery has been renamed to TribeDiscovery as it is exclusively used by TribeService. It adds the tribe blocks to the initial state.
- ZenDiscovery is synchronized on state changes to the last cluster state that is used by the consensus layer and the master service, and does not submit cluster state update tasks anymore to make changes to the disco state (except when becoming master).
Control flow for cluster state updates is now as follows:
- State updates are sent to MasterService
- MasterService gets the latest committed cluster state from the discovery implementation and calculates the next cluster state to publish
- MasterService submits the new prospective cluster state to the discovery implementation for publishing
- Discovery implementation publishes cluster states to all nodes and, once the state is committed, asks the ClusterApplierService to apply the newly committed state.
- ClusterApplierService applies state to local node.
- Getters for DateHisto `interval` and `offset` should return a
long, not double
- Add getter for the filter in a FilterAgg
- Add getters for subaggs / pipelines in base AggregationBuilder
Allow the `Context` to be used in the builder function used within ConstructingObjectParser.
This facilitates scenarios where a constructor argument comes from a URL parameter, or from document id.
The tribe service can take a while to initialize, depending on how many cluster it needs to connect to. This change moves writing the ports file used by tests to before the tribe service is started.
This adds the `index.mapping.single_type` setting, which enforces that indices
have at most one type when it is true. The default value is true for 6.0+ indices
and false for old indices.

This commit fixes some inconsistencies in long GC disruption where we
mixed stopping and suspending when the action we are performing on
threads is suspending which is distinct from stopping a thread.
