This commit fixes the IndexShardTestCase.recoverReplica(IndexShard, IndexShard, boolean)
method where the startReplica parameter was not correctly propagated and the value
true always used instead.
The semantics of the API changed considerably since the documentation was written.
The main change is to remove references to memory reduction (this is related to refresh).
Instead, flush refers to recovery times. I also removed the references to trimming the translog
as the translog may be required for other purposes (operation history for ops based recovery
and complement ongoing file based recoveries).
Closes#32869
The test testSendSnapshotSendsOps is currently using a mock instance of
RecoveryTargetHandler which will be hard to modify when we make the
RecoveryTargetHandler non-blocking. This commit prepares for the
incoming changes by replacing the mock instance with a stub.
Adjust FieldExtractor to handle fields which contain `.` in their
name, regardless where they fall in, in the document hierarchy. E.g.:
```
{
"a.b": "Elastic Search"
}
{
"a": {
"b.c": "Elastic Search"
}
}
{
"a.b": {
"c": {
"d.e" : "Elastic Search"
}
}
}
```

The Inject Annotation was removed from IndicesClusterStateService as
part of reformatting in e11a32e, but this causes CreationException on
cluster startup.
This commit adds a simple method for executing a runnable against a
shard under a primary permit. Today there is only a single caller for
this method, but this there are two upcoming use-cases for which having
this method will help keep the code simpler.
This commit reformats some classes in the index universe with the
purpose of breaking some long method definitions and invocations into a
line per parameter. This has the advantage that for an upcoming change
to these definitions and invocations, the diff for that change will be a
single line per definition or invocation. That makes these sorts of
changes easier to read.
This commit is a simple introduction of the serialization of retention
leases, which will be needed when they are sent across the wire while
synchronizing retention leases to replicas.
DeleteWatchResponse did not allow unknown fields. This commit fixes the
test and ConstructingObjectParser such that it does now allow unknown
fields.

* Default include_type_name to false for get and put mappings.
* Default include_type_name to false for get field mappings.
* Add a constant for the default include_type_name value.
* Default include_type_name to false for get and put index templates.
* Default include_type_name to false for create index.
* Update create index calls in REST documentation to use include_type_name=true.
* Some minor clean-ups around the get index API.
* In REST tests, use include_type_name=true by default for index creation.
* Make sure to use 'expression == false'.
* Clarify the different IndexTemplateMetaData toXContent methods.
* Fix FullClusterRestartIT#testSnapshotRestore.
* Fix the ml_anomalies_default_mappings test.
* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.
We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.
* Make sure to use 'expression == false' in FullClusterRestartIT.
* Mention include_type_name in the REST templates docs.
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.
Closes#29797
This new `hostname` field is meant to be a replacement for its sibling `name` field. See https://github.com/elastic/beats/pull/9943, particularly https://github.com/elastic/beats/pull/9943#discussion_r245932581.
This PR simply adds the new field (`hostname`) to the mapping without removing the old one (`name`), because a user might be running an older-version Beat (without this field rename in it) with a newer-version Monitoring ES cluster (with this PR's change in it).
AFAICT the Monitoring UI isn't currently using the `name` field so no changes are necessary there yet. If it decides to start using the `name` field, it will also want to look at the value of the `hostname` field.
If the checking node no longer holds the shard copy, the assertion
assertSameDocIdsOnShards might fail. This is too harsh since the
assertion is to ensure the consistency between active copies.
Today file-chunks are sent sequentially one by one in peer-recovery. This is a
correct choice since the implementation is straightforward and recovery is
network bound in most of the time. However, if the connection is encrypted, we
might not be able to saturate the network pipe because encrypting/decrypting
are cpu bound rather than network-bound.
With this commit, a source node can send multiple (default to 2) file-chunks
without waiting for the acknowledgments from the target.

This is related to #35975. It implements a file based restore in the
CcrRepository. The restore transfers files from the leader cluster
to the follower cluster. It does not implement any advanced resiliency
features at the moment. Any request failure will end the restore.
Without pulling out the supplier function to the enclosing class, Eclipse 4.8
complains with the following error "No enclosing instance of type
CoordinatorTests.Cluster is available due to some intermediate constructor
invocation"
DeprecationLogger has warning de-duplication logic but it is expensive to run as it involves parsing existing warning headers. This PR changes the upstream bulk indexing code to do its own "event thinning" rather than relying on DeprecationLogger's trimming.

Update the scroll example ascii and Java docs, so it is more clear when to
consume the scroll documents. Before this change the user could loose
the first results if one uses copy & paste.
The constructors in PutPipelineRequest and SimulatePipelineRequest that guess
the xContent type from the provided source are deprecated since 6.0 and each
have a counterpart that takes the xContent type as an explicit argument.
Removing these ctors together with the builders and methods in
ClusterAdminClient that don't have the xContent type as argument.
Today the SyncedFlushService flow is written with multiple nested
callbacks which are hard to read. This commit replaces them with
sequential step listeners.
We recently migrated suggestions to `Writeable`. That allows us to also
clean up empty constructors and methods that called them as they are no
longer needed. They are replaced by constructors that accept a
`StreamInput` instance.
Adds another field, named "request.method", to the structured logfile audit.
This field is present for all events associated with a REST request (not a
transport request) and the value is one of GET, POST, PUT, DELETE, OPTIONS,
HEAD, PATCH, TRACE and CONNECT.
Improve error messages by returning the original SQL statement
declaration instead of trying to reproduce it as the casing and
whitespaces are not preserved accurately leading to small
differences.

Today a peer-recovery may run into a deadlock if the value of
node_concurrent_recoveries is too high. This happens because the
peer-recovery is executed in a blocking fashion. This commit attempts
to make the recovery source partially non-blocking. I will make three
follow-ups to make it fully non-blocking: (1) send translog operations,
(2) primary relocation, (3) send commit files.

* Fix PrimaryAllocationIT Race Condition
* Forcing a stale primary allocation on a green index was tripping the assertion that was removed
* Added a test that this case still errors out correctly
* Made the ability to wipe stopped datanode's data public on the internal test cluster and used it to ensure correct behaviour on the fixed test
* Previously it simply passed because the test finished before the index went green and would NPE when the index was green at the time of the shard store status request, that would then come up empty
* Closes#37345
Since `full` can be common as a field name or part of a field name
(e.g.: `full.name` or `name.full`), it's nice if it's not a reserved
keyword of the grammar so a user can use it without resorting to quotes.

SqlPlugin cannot have more than one public constructor, so for the testing
