This makes a `parentCardinality` available to every `Aggregator`'s ctor
so it can make intelligent choices about how it collects bucket values.
This replaces `collectsFromSingleBucket` and is similar to it but:
1. It supports `NONE`, `ONE`, and `MANY` values and is generally
extensible if we decide we can use more precise counts.
2. It is more accurate. `collectsFromSingleBucket` assumed that all
sub-aggregations live under multi-bucket aggregations. This is
normally true but `parentCardinality` is properly carried forward
for single bucket aggregations like `filter` and for multi-bucket
aggregations configured in single-bucket for like `range` with a
single range.
While I was touching every aggregation I renamed `doCreateInternal` to
`createMapped` because that seemed like a much better name and it was
right there, next to the change I was already making.

In order to ensure that we do not write a broken piece of `RepositoryData`
because the phyiscal repository generation was moved ahead more than one step
by erroneous concurrent writing to a repository we must check whether or not
the current assumed repository generation exists in the repository physically.
Without this check we run the risk of writing on top of stale cached repository data.

returns no results by checking not just the current stage but also following
ones as they can match with in-flight sequences.

Ensure blocking tasks are running before submitting more no-op tasks. This ensures no task would be popped out of the queue unexpectedly, which in turn guarantees the rejection of subsequent authentication request.
Currently we assert that the reason we fail collecting nodes in this
test is due to the fact that no seeds are available or no connections
could be established to cluster_2. However, the collection could fail if
we cannot establish connections to cluster_1. This commit adds that as
an acceptible assertion.
Today, we send operations in phase2 of peer recoveries batch by batch
sequentially. Normally that's okay as we should have a fairly small of
operations in phase 2 due to the file-based threshold. However, if
phase1 takes a lot of time and we are actively indexing, then phase2 can
have a lot of operations to replay.
With this change, we will send multiple batches concurrently (defaults
to 1) to reduce the recovery time.
Backport of #58018
This commit adds validation that when a composable index template is updated, that the number
of unreferenced data streams does not increase. While it is still possible to have data streams
without a backing template (through snapshot restoration), this reduces the chance of getting
in to that scenario.
Relates to #53100
Currently in the recovery request tracker tests we place the futures
into the future map on the GENERIC thread. It is possible that the test
has already advanced past the point where we block on these futures
before they are placed in the map. This introduces other potential
failures as we expect all futures have been completed. This commit fixes
the test by places the futures in the map prior to dispatching.
The composite role that is used for authz, following the authn with an API key,
is an intersection of the privileges from the owner role and the key privileges defined
when the key has been created.
This change ensures that the `#names` property of such a role equals the `#names`
property of the key owner role, thereby rectifying the value for the `user.roles`
audit event field.
The test would try to prepare a `Rounding` even when there aren't any
buckets. This would fail because there is no range over which to prepare
the rounding. It turns out that we don't need the rounding in that case
so we just use `null` then.

* GET data stream API returns additional information (#59128)
This adds the data stream's index template, the configured ILM policy
(if any) and the health status of the data stream to the GET _data_stream
response.
Restoring a data stream from a snapshot could install a data stream that
doesn't match any composable templates. This also makes the `template`
field in the `GET _data_stream` response optional.

This removes the blocking model lookup from the `inference` aggregator's
builder by integrating it into the request rewrite process that loads
stuff asynchronously.

If the recovery source is on an old node (before 7.2), then the recovery
target won't have the safe commit after phase1 because the recovery
source does not send the global checkpoint in the clean_files step. And
if the recovery fails and retries, then the recovery stage won't
transition properly. If a sync_id is used in peer recovery, then the
clean_files step won't be executed to move the stage to TRANSLOG.

Closes#57708
Fixed an issue #59082 introduced. We have to wait for no more operations
in all tests here not just the one we were waiting in already so that the cleanup
operation from the parent class can run without failure.
This request:
```
POST /_search
{
"aggs": {
"a": {
"adjacency_matrix": {
"filters": {
"1": {
"terms": { "t": { "index": "lookup", "id": "1", "path": "t" } }
}
}
}
}
}
}
```
Would fail with a 500 error and a message like:
```
{
"error": {
"root_cause": [
{
"type": "illegal_state_exception",
"reason":"async actions are left after rewrite"
}
]
}
}
```
This fixes that by moving the query rewrite phase from a synchronous
call on the data nodes into the standard aggregation rewrite phase which
can properly handle the asynchronous actions.
Today we do not allow a node to start if its filesystem is readonly, but
it is possible for a filesystem to become readonly while the node is
running. We don't currently have any infrastructure in place to make
sure that Elasticsearch behaves well if this happens. A node that cannot
write to disk may be poisonous to the rest of the cluster.
With this commit we periodically verify that nodes' filesystems are
writable. If a node fails these writability checks then it is removed
from the cluster and prevented from re-joining until the checks start
passing again.

Adds error handling when filling up the queue of the crypto thread pool. Also reduce queue size of the crypto thread pool to 10 so that the queue can be cleared out in time.
Test testAuthenticationReturns429WhenThreadPoolIsSaturated has seen failure on CI when it tries to push 1000 tasks into the queue (setup phase). Since multiple tests share the same internal test cluster, it may be possible that there are lingering requests not fully cleared out from the queue. When it happens, we will not be able to push all 1000 tasks into the queue. But since what we need is just queue saturation, so as long as we can be sure that the queue is fully filled, it is safe to ignore rejection error and just move on.
A number of 1000 tasks also take some to clear out, which could cause the test suite to time out. This PR change the queue to 10 so the tests would have better chance to complete in time.
For #58994 it would be useful to be able to share test infrastructure.
This PR shares `AbstractSnapshotIntegTestCase` for that purpose, dries up SLM tests
accordingly and adds a shared and efficient (compared to the previous implementations)
way of waiting for no running snapshot operations to the test infrastructure to dry things up further.
There have been a few test failures that are likely caused by tests
performing actions that use ML indices immediately after the actions
that create those ML indices. Currently this can result in attempts
to search the newly created index before its shards have initialized.
This change makes the method that creates the internal ML indices
that have been affected by this problem (state and stats) wait for
the shards to be initialized before returning.

* Fix external javadoc reference to server project
This fixes https://github.com/elastic/infra/issues/20103
The problem here is that we rename all artifacts in the :server project to
elasticsearch. The ideal fix would be to rename the gradle project there
to elasticsearch. I'm open to that but it seems quite invasive. Would love to hear
other opinions on that.
The applied alternative minimal invasive fix provided with this PR just takes
potential renamed projects / artifacts (Currently I only see `:server`) into account
when declaring external links.
* Simplify javadoc link base name
* Enforce higher priority for RepositoriesService ClusterStateApplier
This avoids shards allocation failures when the repository instance
comes in the same ClusterState update as the shard allocation.
Backport of #58808
This commit creates a new Gradle plugin to provide a separate task name
and source set for running YAML based REST tests. The only project
converted to use the new plugin in this PR is distribution/archives/integ-test-zip.
For which the testing has been moved to :rest-api-spec since it makes the most
sense and it avoids a small but awkward change to the distribution plugin.
The remaining cases in modules, plugins, and x-pack will be handled in followups.
This plugin is distinctly different from the plugin introduced in #55896 since
the YAML REST tests are intended to be black box tests over HTTP. As such they
should not (by default) have access to the classpath for that which they are testing.
The YAML based REST tests will be moved to separate source sets (yamlRestTest).
The which source is the target for the test resources is dependent on if this
new plugin is applied. If it is not applied, it will default to the test source
set.
Further, this introduces a breaking change for plugin developers that
use the YAML testing framework. They will now need to either use the new source set
and matching task, or configure the rest resources to use the old "test" source set that
matches the old integTest task. (The former should be preferred).
As part of this change (which is also breaking for plugin developers) the
rest resources plugin has been removed from the build plugin and now requires
either explicit application or application via the new YAML REST test plugin.
Plugin developers should be able to fix the breaking changes to the YAML tests
by adding apply plugin: 'elasticsearch.yaml-rest-test' and moving the YAML tests
under a yamlRestTest folder (instead of test)
This allows pipeline aggregations to participate in the up-front rewrite
phase for searches, in particular, it allows them to load data that they
need asynchronously.
