#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.

Currently in the ConnectionManager we lock around the node id. This is
odd because we key connections by the ephemeral id. Upon further
investigation it appears to me that we do not need the locking. Using
the concurrent map, we can ensure that only one connection attempt
completes. There is a very small chance that a new connection attempt
will proceed right as another connection attempt is completing. However,
since the whole process is asynchronous and event oriented
(lightweight), that does not seem to be an issue.
Currently in production instances of Elasticsearch we set a couple of
system properties by default. We currently do not apply all of these
system properties in tests. This commit applies these properties in the
tests.
Due to recent changes in the nio transport, a failure to bind the server
channel has started to be logged at an error level. This exception leads
to an automatic retry on a different port, so it should only be logged
at a trace level.
When we rewrite alias requests, after filtering down to only those that
the user is authorized to see, it can be that there are no aliases
remaining in the request. However, core Elasticsearch interprets this as
_all so the user would see more than they are authorized for. To address
this, we previously rewrote all such requests to have aliases `"*"`,
`"-*"`, which would be interpreted when aliases are resolved as
nome. Yet, this is only needed for get aliases requests and we were
applying it to all alias requests, including remove index requests. If
such a request was sent to a coordinating node that is not the master
node, the request would be rewritten to include `"*"` and `"-*"`, and
then the master would authorize the user for these. If the user had
limited permissions, the request would fail, even if they were
authorized on the index that the remove index action was over. This
commit addresses this by rewriting for get aliases and remove
aliases request types but not for the remove index.

Today the `LeaderChecker` rejects checks from nodes that are not in the current
cluster with the exception message `leader check from unknown node` which
offers no information about why the node is unknown. In fact the node must have
been in the cluster in the recent past, so it might help guide the user to a
more useful log message if we describe it as a `removed node` instead of an
`unknown node`. This commit changes the exception message like this, and also
tidies up a few other loose ends in the `LeaderChecker`.
Today `GatewayMetaState` implements `PersistedState` but it's an error to use
it as a `PersistedState` before it's been started, or if the node is
master-ineligible. It also holds some fields that are meaningless on nodes that
do not persist their states. Finally, it takes responsibility for both loading
the original cluster state and some of the high-level logic for writing the
cluster state back to disk.
This commit addresses these concerns by introducing a more specific
`PersistedState` implementation for use on master-eligible nodes which is only
instantiated if and when it's appropriate. It also moves the fields and
high-level persistence logic into a new `IncrementalClusterStateWriter` with a
more appropriate lifecycle.

This change works around JDK-8213202, which is a bug related to TLSv1.3
session resumption before JDK 11.0.3 that occurs when there are
multiple concurrent sessions being established. Nodes connecting to
each other will trigger this bug when client authentication is
disabled, which is the case for SSLClientAuthTests.
Backport of #46680
The HLRC has a method for reindex, that allows to trigger an async reindex by running RestHighLevelClient.submitReindexTask and RestHighLevelClient.reindex. The delete by query however only has an RestHighLevelClient.deleteByQuery method (and its async counterpart), but no RestHighLevelClient.submitDeleteByQueryTask. So add RestHighLevelClient.submitDeleteByQueryTask

Similarly to what has been done for S3 in #45383, this commit
adds unit tests that verify the behavior of the SDK client and
blob container implementation for Google Storage when the
remote service returns errors.
The main purpose was to add an extra test to the specific retry
logic for 410-Gone errors added in #45963.

Previously, queries on the _index field were not able to specify index aliases.
This was a regression in functionality compared to the 'indices' query that was
deprecated and removed in 6.0.
Now queries on _index can specify an alias, which is resolved to the concrete
index names when we check whether an index matches. To match a remote shard
target, the pattern needs to be of the form 'cluster:index' to match the
fully-qualified index name. Index aliases can be specified in the following query
types: term, terms, prefix, and wildcard.
