Upgrade to lucene 8.5.1 release that contains a bug fix for a bug that might introduce index corruption when deleting data from an index that was previously shrunk.
* [ML] adding prediction_field_type to inference config (#55128)
Data frame analytics dynamically determines the classification field type. This field type then dictates the encoded JSON that is written to Elasticsearch.
Inference needs to know about this field type so that it may provide the EXACT SAME predicted values as analytics.
Here is added a new field `prediction_field_type` which indicates the desired type. Options are: `string` (DEFAULT), `number`, `boolean` (where close_to(1.0) == true, false otherwise).
Analytics provides the default `prediction_field_type` when the model is created from the process.
We can be a little more efficient when aborting a snapshot. Since we know the new repository
data after finalizing the aborted snapshot when can pass it down to the snapshot completion listeners.
This way, we don't have to fork off to the snapshot threadpool to get the repository data when the listener completes and can directly submit the delete task with high priority straight from the cluster state thread.
Sets the default cache size for searchable snapshots to unlimited, which, for testing purposes,
is a better default than the 1GB that we currently have.
We implicitly only supported the prime256v1 ( aka secp256r1 )
curve for the EC keys we read as PEM files to be used in any
SSL Context. We would not fail when trying to read a key
pair using a different curve but we would silently assume
that it was using `secp256r1` which would lead to strange
TLS handshake issues if the curve was actually another one.
This commit fixes that behavior in that it
supports parsing EC keys that use any of the named curves
defined in rfc5915 and rfc5480 making no assumptions about
whether the security provider in use supports them (JDK8 and
higher support all the curves defined in rfc5480).
Prior to the change in #51631 indices were moved to the `TerminalPolicyStep` when their ILM actions
had completed. Once we switched ILM to stop in the last policy configured, these steps because
inaccessible from the policy's perspective. This meant that indices upgraded from ES prior to 7.7.0
could see the following error spammed in their logs every 10 minutes (by default) for every index in
this state:
```
[2020-04-14T15:52:23,764][ERROR][o.e.x.i.IndexLifecycleRunner] [midgar] current step [{"phase":"completed","action":"completed","name":"completed"}] for index [foo] with policy [full] is not recognized
```
This changes the runner to ignore these steps, which is what is desired anyway since the index is
already in the terminal phase.
This change ensures that internal client requests spawned by the
transform persistent task executor and that use the end user security
credentials, have the parent task id assigned. The objective here is
to permit auditing (as well as tracking for debugging purposes) of all
the end-user requests executed on its behalf by persistent tasks.
Because transform tasks already implements graceful shutdown of the
child tasks, this change does not interfere with that by opting out of
the persistent task cancellation of child tasks.

This commit refactors the `AuditTrail` to use the `TransportRequest` as a parameter
for all its audit methods, instead of the current `TransportMessage` super class.
The goal is to gain access to the `TransportRequest#parentTaskId` member,
so that it can be audited. The `parentTaskId` is used internally when spawning tasks
that handle transport requests; in this way tasks across nodes are related by the
same parent task.

Provides basic repository-level stats that will allow us to get some insight into how many
requests are actually being made by the underlying SDK. Currently only tracks GET and LIST
calls for S3 repositories. Most of the code is unfortunately boiler plate to add a new endpoint
that will help us better understand some of the low-level dynamics of searchable snapshots.
Fixes a couple of related failures in SearchableSnapshotsIntegTests.
Firstly, we were not correctly accounting for the case where the cache was so
small that some/all files were read directly; fixed this by only asserting that
the cache is definitely used if the corresponding node has a cache that's large
enough to hold the whole index.
Secondly, we were not permitting shards to be completely empty, which might be
the case (rarely) if there were not many documents indexed and the distribution
of IDs was a bit unlucky; fixed this by asserting that we get stats for at
least one file for the whole index, rather than for each shard separately.
Closes#55126
This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.
In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."
I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.
The isAuthAllowed() method for license checking is used by code that
wants to ensure security is both enabled and available. The enabled
state is dynamic and provided by isSecurityEnabled(). But since security
is available with all license types, an check on the license level is
not necessary. Thus, this change replaces isAuthAllowed() with calling
isSecurityEnabled().
We needlessly send documents to be persisted. If there are no stats added, then we should not attempt to persist them.
Also, this PR fixes the race condition that caused issue: https://github.com/elastic/elasticsearch/issues/54786
Adds support for filters to T-Test aggregation. The filters can be used to

This change converts the module and plugin parameters
for testClusters to be lazy. Meaning that the values
are not resolved until they are actually used. This
removes the requirement to use project.afterEvaluate to
be able to resolve the bundle artifact.
Note - this does not completely remove the need for afterEvaluate
since it is still needed for the custom resource extension.
A small follow-up to #54910. Now that we can generated consistent set of
internal aggs to reduce, we no longer need to keep agg parameters as class
variables.

* [ML] Start gathering and storing inference stats (#53429)
This PR enables stats on inference to be gathered and stored in the `.ml-stats-*` indices.
Each node + model_id will have its own running stats document and these will later be summed together when returning _stats to the user.
`.ml-stats-*` is ILM managed (when possible). So, at any point the underlying index could change. This means that a stats document that is read in and then later updated will actually be a new doc in a new index. This complicates matters as this means that having a running knowledge of seq_no and primary_term is complicated and almost impossible. This is because we don't know the latest index name.
We should also strive for throughput, as this code sits in the middle of an ingest pipeline (or even a query).
This commits adds a timeout when moving ILM back on to a failed step. In
case the master is struggling with processing the cluster update requests
these ones will expire (as we'll send them again anyway on the next ILM
loop run)
ILM more descriptive source messages for cluster updates
Use the configured ILM step master timeout setting

* ILM use Priority.IMMEDIATE for stop ILM cluster update (#54909)
This changes the priority of the cluster state update that stops ILM
altogether to `IMMEDIATE`. We've chosen to change this as it can be useful to
temporarily stop ILM if a cluster is overwhelmed, but a `NORMAL`
priority can see the "stop ILM update" not make it up the tasks queue.
On the same note, we're keeping the `start ILM` cluster update priority
to `NORMAL` on purpose such that we only start `ILM` if the cluster can
handle it.

We added a fancy method to provide random realistic test data to the
reduction tests in #54910. This uses that to remove some of the more
esoteric machinations in the agg tests. This will marginally increase
the coverage of the serialiation tests and, more importantly, remove
some mysterious value generation code that only really made sense for
random reduction tests but was used all over the place. It doesn't, on
the other hand, make the tests shorter. Just *hopefully* more clear.
I only cleaned up a few tests this way. If we like this it'd probably be
worth grabbing others.
We currently create the .async-search index if necessary before performing any action (index, update or delete). Truth is that this is needed only before storing the initial response. The other operations are either update or delete, which will anyways not find the document to update/delete even if the index gets created when missing. This also caused `testCancellation` failures as we were trying to delete the document twice from the .async-search index, once from `TransportDeleteAsyncSearchAction` and once as a consequence of the search task being completed. The latter may be called after the test is completed, but before the cluster is shut down and causing problems to the after test checks, for instance if it happens after all the indices have been cleaned up. It is totally fine to try to delete a response that is no longer found, but not quite so if such call will also trigger an index creation.
With this commit we remove all the calls to createIndexIfNecessary from the update/delete operation, and we leave one call only from storeInitialResponse which is where the index is expected to be created.

Today, we do not clear the recent errors in AutoFollowCoordinator when
we successfully auto-follow indices. This can lead to confusion for the
operators.
This change preserves the task id for internal requests for the `StartDatafeedPersistentTask`.
Task ids are a way to express a relationship between related internal requests.
In this particular case, the task ids are used for debugging and (soon) security auditing,
but not for task cancellation, because there is already a graceful-shutdown of child
internal requests (given a task id) in place.
This change reintroduces the system index APIs for Kibana without the

handled in a separate change.
The APIs introduced here are wrapped versions of the existing REST
endpoints. A new setting is also introduced since the Kibana system
indices' names are allowed to be changed by a user in case multiple
instances of Kibana use the same instance of Elasticsearch.

Guava was removed from Elasticsearch many years ago, but remnants of it
remain due to transitive dependencies. When a dependency pulls guava
into the compile classpath, devs can inadvertently begin using methods
from guava without realizing it. This commit moves guava to a runtime
dependency in the modules that it is needed.
Note that one special case is the html sanitizer in watcher. The third
party dep uses guava in the PolicyFactory class signature. However, only
calling a method on the PolicyFactory actually causes the class to be
loaded, a reference alone does not trigger compilation to look at the
class implementation. There we utilize a MethodHandle for invoking the
relevant method at runtime, where guava will continue to exist.

This removes pipeline aggregators from the aggregation result tree
except for a single field used for backwards compatibility with pre-7.8
versions of Elasticsearch. That field isn't populated unless we are
serializing to pre-7.8 Elasticsearch. So, good news! We no longer build
pipeline aggregators on the data node. Most of the time.
This allows subclasses of `InternalAggregationTestCase` to make a `List`
of values to reduce so that it can make values that are realistic
*together*. The first use of this is with `InternalTTest` which uses it
to make results that don't cause their `sum` field to wrap. It'd likely
be useful for a ton of other aggs but just one for now.
The usage of blank lines as separator between tests can be tricky to
deal with in case of merges where such lines can be added by accident.
Further more counting non-consecutive lines is non-intuitive.
The tests have been aligned to use ; at the end of the query and
exceptions so that the presence or absence of empty lines is irrelevant.
The parsing of the spec has been changed to perform validation to not
allow invalid/incomplete specs to cause exceptions.

`AsyncSearchActionTests` currently fails quite often. That is since the introduction of `RestSubmitAsyncSearchActionTests` which indirectly manipulates the channels being tracked in `RestCancellableNodeClient`. There are channels left in the map after `RestSubmitAsyncSearchActionTests` is run, and later `AsyncSearchActionTests` checks that there are no channels in the map which makes each test method fail. This is particularily hard to reproduce as the order in which tests are run appears to be platform dependent.
The test cluster assertion that there are no channels in the map only makes sense in the context of internal cluster tests, while there may be collisions with unit tests that register http channels as part of their testing.
This can be solved by renaming `AsyncSearchActionTests` to `AsyncSearchActionIT`. This way it won't be run as part of unit tests but rather within another JVM where the number of channels is `0` and such assumption holds, because there are no expected manual manipulation of the channels.

in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
* Comprehensively test supported/unsupported field type:agg combinations (#52493)
This adds a test to AggregatorTestCase that allows us to programmatically
verify that an aggregator supports or does not support a particular
field type. It fetches the list of registered field type parsers,
creates a MappedFieldType from the parser and then attempts to run
a basic agg against the field.
A supplied list of supported VSTypes are then compared against the
output (success or exception) and suceeds or fails the test accordingly.

This adds the ability for the IdP to define wildcard service
providers in a JSON file within the ES node's config directory.
If a request is made for a service provider that has not been
registered, then the set of wildcard services is consulted. If the
SP entity-id and ACS match one of the wildcard patterns, then a
dynamic service provider is defined from the associated mustache
template.

This commit clarifies the autoscaling feature flag registration system
property. The intention is that this system property is:
- unset in snapshot builds
- unset, true, or false in release builds
- in release builds, unset behaves the same as false
- therefore, we only register the enabled flag if the build is a
snapshot build, or the build is a release build and the system
property is set to true
This commit clarifies that intention, and removed a confusion situation
where the AUTOSCALING_FEATURE_FLAG_REGISTERED field would be set to
false in a snapshot build, even though we were going to register the
setting.

The allowTrial flag is always true, since trial licenses act as though
everything is licensed. This commit removes the allowTrial flag in
license checking helper methods.
Pipeline aggregations like `stats_bucket`, `sum_bucket`, and
`percentiles_bucket` only operate on buckets that have multiple buckets.
This adds support for those aggregations to `geo_distance`, `ip_range`,
`auto_date_histogram`, and `rare_terms`.
This all happened because we used a marker interface to mark compatible
aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget
to implement the interface.
This replaces the marker interface with an abstract method in
`AggregationBuilder`, `bucketCardinality` which makes you return `NONE`,
`ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At
this point `ONE` and `NONE` amount to about the same thing, but I
suspect that'll be a useful distinction when validating bucket sorts.

In order to prepare the `AliasOrIndex` abstraction for the introduction of data streams,
the abstraction needs to be made more flexible, because currently it really can be only
an alias or an index.
* Renamed `AliasOrIndex` to `IndexAbstraction`.
* Introduced a `IndexAbstraction.Type` enum to indicate what a `IndexAbstraction` instance is.
* Replaced the `isAlias()` method that returns a boolean with the `getType()` method that returns the new Type enum.
* Moved `getWriteIndex()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface.
* Moved `getAliasName()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface and renamed it to `getName()`.
* Removed unnecessary casting to `IndexAbstraction.Alias` by just checking the `getType()` method.

Today the security plugin stashes a copy of the environment in its
constructor, and uses the stashed copy to construct its components even
though it is provided with an environment to create these
components. What is more, the environment it creates in its constructor
is not fully initialized, as it does not have the final copy of the
settings, but the environment passed in while creating components
does. This commit removes that stashed copy of the environment.

Currently all of our transport protocol decoding and aggregation occurs
in the individual transport modules. This means that each implementation
(test, netty, nio) must implement this logic. Additionally, it means
that the entire message has been read from the network before the server
package receives it.
This commit creates a pipeline in server which can be passed arbitrary
bytes to handle. Internally, the pipeline will decode, decompress, and
aggregate the messages. Additionally, this allows us to run many
megabytes of bytes through the pipeline in tests to ensure that the
logic works.
This work will enable future work:
Circuit breaking or backoff logic based on message type and byte
in the content aggregator.
Sharing bytes with the application layer using the ref counted
releasable network bytes.
Improved network monitoring based specifically on channels.
Finally, this fixes the bug where we do not circuit break on the correct
message size when compression is enabled.

Today we assign CCR persistent tasks to nodes with the data role. It
could be that the data node is not capable of connecting to remote
clusters, in which case the task will fail since it can not connect to
the remote cluster with the leader shard. Instead, we need to assign
such tasks to nodes that are capable of connecting to remote
clusters. This commit addresses this by enabling such persistent tasks
to only be assigned to nodes that have the data role, and also have the
remote cluster client role.
optimize transform for group_by on date_histogram by injecting an additional range query. This limits the number of search and index requests and avoids unnecessary updates. Only recent buckets get re-written.

This commit causes negative TimeValues, other than -1 which is sometimes used as
a sentinel value, to be rejected during parsing.
Also introduces a hack to allow ILM to load policies which were written to the
cluster state with a negative min_age, treating those values as 0, which should
match the behavior of prior versions.
The NodesStatsRequest class uses a set of strings for its internal
serialization. This commit updates the class's interface so that we
no longer use hard-coded getters and setters, but rather
methods that add strings directly. For example, the old way of
adding "os" metrics to a request would be to call request.os(true).
The new way of doing this is to call request.addMetric("os").
For the time being, the canonical list of metrics is an enum in
NodesStatsRequest. This will eventually be replaced with something
pluggable.
This commit populates the _stats API response with sensible "empty"
`data_counts` and `memory_usage` objects when the job itself
has not started reporting them.

Currently we set the defaults for ccsMinimizeRoundtrips, preFilterShardSize and
requestCache on the HLRC SubmitAsyncSearchRequest in the constructor. This is no
longer needed since we now only send the parameters along with the rest request
that are supported (omitting e.g. ccsMinimizeRoundtrips) and the correct
defaults are set on the client side. This change removes setting and sending
these defaults where possible, leaving only the overwrite of batchedReduceSize
with a default value of 5, since the default used in the vanilla SearchRequest
is 512. However, we don't need to send this value along as a request parameter
if its the default since the correct one will be set on the receiving end if no
value is specified.
Also adding tests for RestSubmitAsyncSearchAction that check the correct
defaults are set when parameters are missing on the server side.

When get filters is called without setting the `size`

Xpack license state contains a helper method to determine whether
security is disabled due to license level defaults. Most code needs to
know whether security is enabled, not disabled, but this method exists
so that the security being explicitly disabled can be distinguished from
licence level defaulting to disabled. However, in the case that security
is explicitly disabled, the handlers in question are never registered,
so security is implicitly not disabled explicitly, and thus we can share
a single method to know whether licensing is enabled.
With the addition of a formal role for nodes indicating remote cluster connection, the transform specific attribute `node.attr.transform.remote_connect` is no longer necessary.

This drop the "top level" pipeline aggregators from the aggregation
result tree which should save a little memory and a few serialization
bytes. Perhaps more imporantly, this provides a mechanism by which we
can remove *all* pipelines from the aggregation result tree. This will
save quite a bit of space when pipelines are deep in the tree.
Sadly, doing this isn't simple because of backwards compatibility. Nodes
before 7.7.0 *need* those pipelines. We provide them by setting passing
a `Supplier<PipelineTree>` into the root of the aggregation tree that we
only call if we need to serialize to a version before 7.7.0.
This solution works for cross cluster search because we always reduce
the aggregations in each remote cluster and then forward them back to
the coordinating node. Its quite possible that the coordinating node
needs the pipeline (say it is version 7.1.0) and the gateway node in the
remote cluster doesn't (version 7.7.0). In that case the data nodes
won't send the pipeline aggregations back to the gateway node.
Critically, the gateway node *will* send the pipeline aggregations back
to the coordinating node. This is all managed with that
`Supplier<PipelineTree>`, but *how* it is managed is a bit tricky.
* transform.cat should live in the cat namespace.
Similarly to to ml cat API's also living in the `cat` namespace.

This change merges the "feature-internal-idp" branch into Elasticsearch.
This introduces a small identity-provider plugin as a child of the x-pack module.
This allows ES to act as a SAML IdP, for users who are authenticated against the
Elasticsearch cluster.
This feature is intended for internal use within Elastic Cloud environments
and is not supported for any other use case. It falls under an enterprise license tier.
The IdP is disabled by default.

Submit async search forces pre_filter_shard_size for the underlying search that it creates.
With this commit we also prevent users from overriding such default as part of request validation.
This commit adds an explicit cancellation of the search task if
the initial async search submit task is cancelled (connection closed by the user).
This was previously done through the cancellation of the parent task but we don't
handle grand-children cancellation yet so we have to manually cancel the search task
in order to ensure that shard actions are cancelled too.
This change can be considered as a workaround until #50990 is fixed.

It is possible for ML jobs to open lazily if the "allow_lazy_open"
option in the job config is set to true. Such jobs wait in the
"opening" state until a node has sufficient capacity to run them.
This commit fixes the bug that prevented datafeeds for jobs lazily
waiting assignment from being started. The state of such datafeeds
is "starting", and they can be stopped by the stop datafeed API
while in this state with or without force.
