When the ML native multi-node tests use _cat/indices/_all
and the request goes to a non-master node, _all is
translated to a list of concrete indices by the authz layer
on the coordinating node before the request is forwarded
to the master node. Then it is possible for the master
node to return an index_not_found_exception if one of
the concrete indices that was expanded on the
coordinating node has been deleted in the meantime.
(#47159 has been opened to track the underlying problem.)
It has been observed that the index that gets deleted when
the problem affects the ML native multi-node tests is
always the ML notifications index. The tests that fail are
only interested in the presence or absense of ML results
indices. Therefore the workaround is to only _cat indices
that match the ML results index pattern.
Fixes#45652
In the current implementation, the validation of the role query
occurs at runtime when the query is being executed.
This commit adds validation for the role query when creating a role
but not for the template query as we do not have the runtime
information required for evaluating the template query (eg. authenticated user's
information). This is similar to the scripts that we
store but do not evaluate or parse if they are valid queries or not.
For validation, the query is evaluated (if not a template), parsed to build the
QueryBuilder and verify if the query type is allowed.

This change merges the `ShardSearchTransportRequest` and `ShardSearchLocalRequest`
into a single `ShardSearchRequest` that can be used to create a SearchContext.

This PR changes the ingest executing to be non blocking
by adding an additional method to the Processor interface
that accepts a BiConsumer as handler and changing
IngestService#executeBulkRequest(...) to ingest document
in a non blocking fashion iff a processor executes
in a non blocking fashion.
This is the second PR that merges changes made to server module from
the enrich branch (see #32789) into the master branch.
The plan is to merge changes made to the server module separately from
the pr that will merge enrich into master, so that these changes can
be reviewed in isolation.
This change originates from the enrich branch and was introduced there
in #43361.
Today if metadata persistence is excessively slow on a master-ineligible node
then the `ClusterApplierService` emits a warning indicating that the
`GatewayMetaState` applier was slow, but gives no further details. If it is
excessively slow on a master-eligible node then we do not see any warning at
all, although we might see other consequences such as a lagging node or a
master failure.
With this commit we emit a warning if metadata persistence takes longer than a
configurable threshold, which defaults to `10s`. We also emit statistics that
record how much index metadata was persisted and how much was skipped since
this can help distinguish cases where IO was slow from cases where there are
simply too many indices involved.
Backport of #47005.
This commit adds support for POST requests to the SLM `_execute` API,
because POST is a more appropriate HTTP verb for this action as it is
not idempotent. The docs are also changed to favor POST over PUT,
although PUT is not removed or officially deprecated.
Currently the logic to check if a connection to a remote discovery node
exists and otherwise create a proxy connection is mixed with the
collect nodes, cluster connection lifecycle, and other
RemoteClusterConnection logic. This commit introduces a specialized
RemoteConnectionManager class which handles the open connections.
Additionally, it reworks the "round-robin" proxy logic to create the list
of potential connections at connection open/close time, opposed to each
time a connection is requested.
We can have a large number of shard copies in this test. For example,
the two recent failures have 24 and 27 copies respectively and all
replicas have to copy segment files as their stores are corrupted. Our
CI needs more than 30 seconds to start all these copies.
Note that in two recent failures, the cluster was green just after the
cluster health timed out.
Closes#41899
* ILM: parse origination date from index name (#46755)
Introduce the `index.lifecycle.parse_origination_date` setting that
indicates if the origination date should be parsed from the index name.
If set to true an index which doesn't match the expected format (namely
`indexName-{dateFormat}-optional_digits` will fail before being created.
The origination date will be parsed when initialising a lifecycle for an
index and it will be set as the `index.lifecycle.origination_date` for
that index.
A user set value for `index.lifecycle.origination_date` will always
override a possible parsable date from the index name.

* Drop usage of Map.of to be java 8 compliant
* Wait for snapshot completion in SLM snapshot invocation
This changes the snapshots internally invoked by SLM to wait for
completion. This allows us to capture more snapshotting failure
scenarios.
For example, previously a snapshot would be created and then registered
as a "success", however, the snapshot may have been aborted, or it may
have had a subset of its shards fail. These cases are now handled by
inspecting the response to the `CreateSnapshotRequest` and ensuring that
there are no failures. If any failures are present, the history store
now stores the action as a failure instead of a success.

Using arrays of objects with embedded IDs is preferred for new APIs over
using entity IDs as JSON keys. This commit changes the SLM stats API to
use the preferred format.
#46180 added support for the `[source,console]`
language for snippets which should be tested.
This removes support for the `// CONSOLE` magic comment,
which serve a similar purpose.
Snippets that include the `// CONSOLE` magic comment will return
an exception.
We should not be quietly ignoring a corrupted shard-level index-N
blob. Simply creating a new empty shard-level index-N and moving
on means that all snapshots of that shard show `SUCESS` as their
state at the repository root but are in fact broken.
This change at least makes it visible to the user that they can't
snapshot the given shard any more and forces the user to move on
to a new repository since the current one is broken and will not
allow snapshotting the inconsistent shard again.
Also, this change stops the delete action for shards with broken
index-N blobs instead of simply deleting all blobs in the path
containing the broken index-N. This prevents a temporarily
broken/missing index-N blob from corrupting all snapshots of
that shard.
Simplify `SnapshotResiliencyTests` to more closely
match the structure of `AbstractCoordinatorTestCase` and allow for
future drying up between the two classes:
* Make the test cluster nodes a nested-class in the test cluster itself
* Remove the needless custom network disruption implementation and
simply track disconnected node ids like `AbstractCoordinatorTestCase`
does
* [ML][Inference] Feature pre-processing objects and functions (#46777)
To support inference on pre-trained machine learning models, some basic feature encoding will be necessary. I am using a named object serialization approach so new encodings/pre-processing steps could be added in the future.
This PR lays down the ground work for 3 basic encodings:
* HotOne
* Target Mean
* Frequency
More feature encodings or pre-processings could be added in the future:
* Handling missing columns
* Standardization
* Label encoding
* etc....
* fixing compilation for namedxcontent tests
Today we log and swallow exceptions during cluster state application, but such
an exception should not occur. This commit adds assertions of this fact, and
updates the Javadocs to explain it.

This commit clarifies and points out that the Role management UI and
the Role management API cannot be used to manage roles that are
defined in roles.yml and that file based role management is
intended to have a small administrative scope and not handle all
possible RBAC use cases.
This change allows for the caller of the `saml/prepare` API to pass
a `relay_state` parameter that will then be part of the redirect
URL in the response as the `RelayState` query parameter.
The SAML IdP is required to reflect back the value of that relay
state when sending a SAML Response. The caller of the APIs can
then, when receiving the SAML Response, read and consume the value
as it see fit.
We emit a debug log message whenever a child circuit breaker trips (in
`ChildMemoryCircuitBreaker#circuitBreak(String, long)`) but we never
emit a log message when the parent circuit breaker trips. As this is
more likely to happen with the real memory circuit breaker it is not
possible to detect this in the logs. With this commit we add a log
message on the same log level (debug) when the parent circuit breaker
trips.
This change adds a check to the migration tool that warns about the deprecated
`enabled` setting for the `_field_names` field on 7.x indices and issues a
warning for templates containing this setting, which has been removed
with 8.0.

Similarly to what has been done for S3 and GCS, this commit
adds unit tests that verify the retry logic of the Azure SDK
client implementation when the remote service returns errors.
It only tests the retry logic in case of errors and not in
case of timeouts because Azure client timeout options are
not exposed as settings.
Although they do not support eager_global_ordinals, ip fields use global
ordinals for certain aggregations like 'terms'.
This commit also corrects a reference to the sampler aggregation.
We speculatively added support for `regexp` queries on the `_index` field in
#34089 (this functionality was not actually requested by a user). Supporting
regex logic adds complexity to the `_index` field for not much gain, so we
would like to remove it.
From an end-to-end test it turns out this functionality never even worked in
the first place because of an error in how regex flags were interpreted! For
this reason, we can remove support for `regexp` on `_index` without a
deprecation period.
Relates to #46640.
