Add a more detailed section about what exceptions to expect from the blocking
calls in this class and removing the mostly redundant mentions of the
IOExceptions from each method javadoc since it doesn't give much details about
the expected exceptions anyway.
Closes#30334
This commit adds an empty CcrRepository snapshot/restore repository.
When a new cluster is registered in the remote cluster settings, a new
CcrRepository is registered for that cluster.
This is implemented using a new concept of "internal repositories".
RepositoryPlugin now allows implementations to return factories for
"internal repositories". The "internal repositories" are different from
normal repositories in that they cannot be registered through the
external repository api. Additionally, "internal repositories" are local
to a node and are not stored in the cluster state.
The repository will be unregistered if the remote cluster is removed.
* Move `createRepository` call out of cluster state tasks
* Now only `RepositoriesService#applyClusterState` manipulates `this.repositories`
* Closes#9488
This commit makes `document`, `update`, `explain`, `termvectors` and `mapping`
typeless APIs work on indices that have a type whose name is not `_doc`.
Unfortunately, this needs to be a bit of a hack since I didn't want calls with
random type names to see documents with the type name that the user had chosen
upon type creation.
The `explain` and `termvectors` do not support being called without a type for
now so the test is just using `_doc` as a type for now, we will need to fix
tests later but this shouldn't require further changes server-side since passing
`_doc` as a type name is what typeless APIs do internally anyway.

It is important that all shards of a given index have the same
`indexCreatedVersionMajor` to Lucene, or eg. merging those shards is going to
be considered illegal. At the moment, we use the latest Lucene version when
creating a shard, which could cause shards to have different created versions
eg. in case of forced allocation. This commit makes sure to reuse the
appropriate Lucene version in order to avoid such issues.
Closes#33826
Today we configure the soft-deletes field iff soft-deletes enabled.
Although this choice was correct, it prevents an engine with
soft-deletes disabled from opening a Lucene index with soft-deletes.
Moreover, this change should not have any side-effect if a Lucene index
does not have any soft-deletes.

AutoFollowCoordinator should take into account that after auto following
an index and while updating that a leader index has been followed, that
the auto follow pattern may have been removed via delete auto follow patterns
api.
Also fixed a bug that when a remote cluster connection has been removed,
the auto follow coordinator does not die when it tries get a remote client for
that cluster.
Closes#35480
This commit changes how an operation which requires all index shard
operations permits is executed when a primary term update is required:
the operation and the update are combined so that the operation is
executed after the primary term update under the same blocking
operation.

This change adds a soft limit to open scroll contexts that can be controlled with the dynamic cluster setting `search.max_open_scroll_context` (defaults to 500).
The rest interface for remove-policy-from-index API does not support
`_ilm/remove`, it requires that an `{index}` pattern be defined in
the URL path. This fixes the rest-api-spec to reflect the implementation
This commit is part of our plan to deprecate and ultimately remove the
use of _xpack in the REST APIs.
* Add deprecation for /_xpack/monitoring/_bulk in favor of /_monitoring/bulk
* Removed xpack from the rest-api-spec and tests
* Removed xpack from the Action name
* Removed MonitoringRestHandler as an unnecessary abstraction
* Minor corrections to comments

Given that we check the max buckets limit on each shard when collecting the buckets, and that non final reduction cannot add buckets (see #35921), there is no point in counting and checking the number of buckets as part of non final reduction phases.
Such check is still needed though in the final reduction phases to make sure that the number of returned buckets is not above the allowed threshold.
Relates somehow to #32125 as we will make use of non final reduction phases in CCS alternate execution mode and that increases the chance that this check trips for nothing when reducing aggs in each remote cluster.
When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.
Closes#35293
* Moved method `canOpenIndex` is only used in tests -> moved to test CP
* Simplify `org.elasticsearch.index.store.Store#renameTempFilesSafe`

The problem showed up on debian 8 which uses aufs docker storage
driver by default as opposed to overlay2 used on other distros.
aufs does not support acls and thus the failure.
The --use-ntvfs option instructs samba not to rely on acls.
From what I can tell this is an implementation detail that should not
affect the tests ( which continue to pass )
Currently is `java` is not in $PATH the preinst script fails
prematurely and prevents an appropriate message from getting displayed
to the user.
Make package installation more user friendly when java is not in
$PATH and add a test for it.
Also use a she-bang in the preinst script, as, at least in Debian,
maintainer scripts must start with the #! convention [1].

* Replace Streamable w/ Writeable in BaseTasksRequest and subclasses
This commit replaces usages of Streamable with Writeable for the
BaseTasksRequest / TransportTasksAction classes and subclasses of
these classes.

Introduces a debug log message when a bind fails and a trace message
when a bind succeeds.
It may seem strange to only debug a bind failure, but failures of this
nature are relatively common in some realm configurations (e.g. LDAP
realm with multiple user templates, or additional realms configured
after an LDAP realm).
The logic in the dockerComposeSupported method currently returns false
even when docker and docker compose are available on the build machine.
This change updates the check to see if docker compose is available in
one of the two paths and allows the `tests.fixture.enabled` property to
disable the tests even if docker compose is available.
Adds about a minute worth of backoffs and retries to saving task
results so it is *much* more likely that a busy cluster won't lose task
results. This isn't an ideal solution to losing task results, but it is
an incremental improvement. If all of the retries fail when still log
the task result, but that is far from ideal.
Closes#33764
The new limit on the number of open shards in a cluster may be
interpreted by users as a sizing recommendation, but it is not. This
clarifies in the documentation that this is a safety limit, not a
recommendation.
Empty buckets don't need to be added when performing an incremental reduction step, they can be added later in the final reduction step. This will allow us to later remove the max buckets limit when performing non final reduction.
This commit documents how Index Lifecycle Management
interacts with snapshot/restore, and documents a workaround
for situations in which ILM should not immediately resume
managing an index after it is restored.
This is a follow-up to #35144. That commit made the underlying
connection opening process in TcpTransport asynchronous. However the
method still blocked on the process being complete before returning.
This commit moves the blocking to the ConnectionManager level. This is
another step towards the top-level TransportService api being async.
This change adds the support for rest_total_hits_as_int
in the watcher search inputs. Setting this parameter in the request
will transform the search response to contain the total hits as
a number (instead of an object).
Note that this parameter is currently a noop since #35849 is not
merged.
Closes#36008
