Now that #61324 is merged it is possible for the find_file_structure
endpoint to suggest using date_nanos fields for timestamps where
the timestamp format provides greater than millisecond accuracy.
This pull request adds a new set of APIs that allows tracking the number of requests performed
by the different registered repositories.
In order to avoid losing data, the repository statistics are archived after the repository is closed for
a configurable retention period `repositories.stats.archive.retention_period`. The API exposes the
statistics for the active repositories as well as the modified/closed repositories.

We've had some discussions around the user experience when using runtime fields. Although we do plan on having multiple runtime fields implementation (e.g. grok, lookup etc.) which could be exposed as different field types, we decided to expose all runtime fields under the same `runtime` type. At the moment, the only implementation will be through scripts, hence a `script` must be specified. In the future, there will be other ways to generate values for runtime fields besides scripts.
This translates also to renaming the RuntimeScriptFieldMapper class to RuntimeFieldMapper .

Today, the terms aggregation reduces multiple aggregations at once using a map
to group same buckets together. This operation can be costly since it requires
to lookup every bucket in a global map with no particular order.
This commit changes how term buckets are sorted by shards and partial reduces in
order to be able to reduce results using a merge-sort strategy.
For bwc, results are merged with the legacy code if any of the aggregations use
a different sort (if it was returned by a node in prior versions).

Moving the data stream yaml tests to xpack plugin module has the following benefits:
* The tests are ran both with security enabled (as part of xpack/plugin integTest)
and disabled (as part of xpack/plugin/data-stream/qa/rest integTest).
* and running the tests in mixed cluster qa environment.
This commit includes the work that has been done on the runtime fields feature branch until now. The high level tasks are listed in #59332. The tasks that have not yet been completed can be worked on after merging the feature branch.
We are adding a new x-pack plugin called runtime-fields that plugs in a custom mapper which allows to define runtime fields based on a script.
The changes included in this commit that were made outside of the x-pack/plugin/runtime-fields directory are minimal and revolve around 1) making the ScriptService available while parsing index mappings so that the scripts associated to runtime fields can be compiled 2) sharing code to manipulate ranges etc. as it can be reused in runtime fields.

Simplifies allocation for snapshot-backed shards by always making the recovery source "from snapshot" for those
snapshot-backed shards (instead of "recover from local or from empty store"). Also let's the balancer pick a node which
to allocate the snapshot-backed shard to (which takes number of shards on each node into account unlike the current
implementation which just picks whatever node we are allowed to allocate to, with no notion of "balancing" at all).
During prewarming of a Lucene file a CacheFile is acquired and
then locked for the duration of the prewarming, ie locked until all
the part of the file has been downloaded and written to cache on
disk. The locking (executed with CacheFile#fileLock()) is here to
prevent the cache file to be evicted while it is prewarming.
But holding the lock may take a while for large files, specially since
restoring snapshot files now respects the
indices.recovery.max_bytes_per_sec setting of 40mb (#58658),
and this can have bad consequences like preventing the CacheFile
to be evicted, opened or closed. In manual tests this bug slow
downs various requests like mounting a new searchable snapshot
index or deleting an existing one that is still prewarming.
This commit reduces the time the lock is held during prewarming so
that the read lock is only required when actively writing to the CacheFile.
* [ML] adds new n_gram_encoding custom processor (#61578)
This adds a new `n_gram_encoding` feature processor for analytics and inference.
The focus of this processor is simple ngram encodings that allow:
- multiple ngrams [1..5]
- Prefix, infix, suffix
Previously, we added a copy of the `_id` during reindexing and sorted
the destination index on that. This allowed us to traverse the docs in the
destination index in a stable order multiple times and with efficiency.
However, the destination index being sorted means we cannot have `nested`
typed fields. This is a problem as it does not allow us to provide
a good experience with our evaluate API when it comes to computing
metrics for specific classes, features, etc.
This commit changes the approach in order to result to a destination
index that allows nested fields.
Instead of adding a copy of the `_id` field, we now add an incremental
id that we can use to traverse the docs in a stable order. We also
ensure we always assign the same incremental id to the same doc from
the source indices by sorting on `_seq_no` during reindexing. That
in combination with the reindexing API using scroll gives us a stable
order as scroll uses the (`_index`, `_doc`, shard_id) tuple to resolve ties.
The extractor now does not need to scroll. Instead we sort on the incremental
id and we do ranged searches to avoid the sort-all-docs overhead.
Finally, the `TestDocsIterator` is simply changed to search_after the incremental id.
With these changes data frame analytics jobs do not use scroll at any part.
Having all these in place, the commit adds the `nested` types to the necessary
fields of `classification` and `regression` analyses results.

A role mapping with the following content:
"rules": { "field": { "userid" : "admin" } }
will never match because `userid` is not a valid field. The correct
field is `username`.
This change adds DEBUG logging when an undefined field is referenced.
The choice to use DEBUG rather than INFO/WARN is that the set of
fields is partially dynamic (e.g. the `metadata.*` fields), so
it may be perfectly reasonable to check a field that is not defined
for that user. For example this rule:
"rules": { "field": { "metadata.ranking" : "A" } }
would generate a log message for an unranked user, which would
erroneously suggest that such a rule is an error.
This DEBUG logging will assist in diagnosing problems, without
introducing that confusion.

There are currently half a dozen ways to add plugins and modules for
test clusters to use. All of them require the calling project to peek
into the plugin or module they want to use to grab its bundlePlugin
task, and then both depend on that task, as well as extract the archive
path the task will produce. This creates cross project dependencies that
are difficult to detect, and if the dependent plugin/module has not yet
been configured, the build will fail because the task does not yet
exist.
This commit makes the plugin and module methods for testclusters
symmetetric, and simply adding a file provider directly, or a project
path that will produce the plugin/module zip. Internally this new
variant uses normal configuration/dependencies across projects to get
the zip artifact. It also has the added benefit of no longer needing the
caller to add to the test task a dependsOn for bundlePlugin task.
The main changes are:
* Fix custom params are missing when using template or script in watcher's
logging action or jira action.
* Add yaml tests to test passing params to template or script successfully.

The eql search api redirects to the search api. For this reason the eql
search api could work with concrete data stream names. However if security
is enabled and a data stream name snippet with a wildcard was used then
it could not resolve this expressions. This is because the EqlSearchRequest
class didn't overwrite the `includeDataStreams()` method. This pr fixes this,
so that the security layer can properly expand data stream name wildcard
expressions for the eql search api.
This commit also moves the eql data stream test to xpack rest tests,
so that the test runs with security enabled. This is required to reproduce
the bug.

We frequently use `long`s with `BitArray` in aggs and right now we have
to assert that the `long` fits in an `int`. This adds support for `long`
to `BitArray` so we don't need those assertions.
This fixes a bug introduced by #61782. In that PR I thought I could
simplify the persistence of progress by using the progress straight
from the stats holder in the task instead of calling the get
stats action. However, I overlooked that it is then possible to
have stale progress for the reindexing task as that is only updated
when the get stats API is called.
In this commit this is fixed by updating reindexing task progress
before persisting the job progress. This seems to be much more
lightweight than calling the get stats request.

persist progress. If the job is later restarted, this means
we do not correctly restore from where we can but instead
we start the job from scratch and have to redo the reindexing

@ywangd made an awesome analysis on why this test is failing, over
at https://github.com/elastic/elasticsearch/issues/55816#issuecomment-620913282
This change makes it so that we use the same client to perform a
refresh of a token, as we use to subsequently attempt to authenticate
with the refreshed token. This ensures the tests are failing and is
a good approximation of how we expect the same client doing the
refresh, to also perform the subsequent authentication in real life
uses.
The errors we were seeing from users have disappeared after #55114
so we deem our behavior safe.
System indices can be snapshotted and are therefore potential candidates
to be mounted as searchable snapshot indices. As of today nothing
prevents a snapshot to be mounted under an index name starting with .
and this can lead to conflicting situations because searchable snapshot
indices are read-only and Elasticsearch expects some system indices
to be writable; because searchable snapshot indices will soon use an
internal system index (#60522) to speed up recoveries and we should
prevent the system index to be itself a searchable snapshot index
(leading to some deadlock situation for recovery).
This commit introduces a changes to prevent snapshots to be mounted
as a system index.
BlobStoreCacheService implements ClusterStateListener in order to

available(in isExpectedCacheGetException()) and logs as DEBUG
we can safely remove the ready flag.
This is a minor refactor where the job node load logic (node availability, etc.) is refactored into its own class.
This will allow future things (i.e. autoscaling decisions) to use the same node load detection class.

Part of #46106. Simplify the implementation of deprecation logging by
relying of log4j more completely, and implementing additional behaviour
through custom appenders and filters.
This commit adds the functionality to allocate newly created indices on nodes in the "hot" tier by
default when they are created.
This does not break existing behavior, as nodes with the `data` role are considered to be part of
the hot tier. Users that separate their deployments by using the `data_hot` (and `data_warm`,
`data_cold`, `data_frozen`) roles will have their data allocated on the hot tier nodes now by
default.
This change is a little more complicated than changing the default value for
`index.routing.allocation.include._tier` from null to "data_hot". Instead, this adds the ability to
have a plugin inject a setting into the builder for a newly created index. This has the benefit of
allowing this setting to be visible as part of the settings when retrieving the index, for example:
```
// Create an index
PUT /eggplant
// Get an index
GET /eggplant?flat_settings
```
Returns the default settings now of:
```json
{
"eggplant" : {
"aliases" : { },
"mappings" : { },
"settings" : {
"index.creation_date" : "1597855465598",
"index.number_of_replicas" : "1",
"index.number_of_shards" : "1",
"index.provided_name" : "eggplant",
"index.routing.allocation.include._tier" : "data_hot",
"index.uuid" : "6ySG78s9RWGystRipoBFCA",
"index.version.created" : "8000099"
}
}
}
```
After the initial setting of this setting, it can be treated like any other index level setting.
This new setting is *not* set on a new index if any of the following is true:
- The index is created with an `index.routing.allocation.include.<anything>` setting
- The index is created with an `index.routing.allocation.exclude.<anything>` setting
- The index is created with an `index.routing.allocation.require.<anything>` setting
- The index is created with a null `index.routing.allocation.include._tier` value
- The index was created from an existing source metadata (shrink, clone, split, etc)

The check introduced by #60640 for scroll searches, in which we log
if the index access control before the query and fetch phases differs
from when the scroll context is created, is too strict, leading to spurious
warning log messages.
The check verifies instance equality but this assumes that the fetch
phase is executed in the same thread context as the scroll context
validation. However, this is not true if the scroll search is executed
cross-cluster, and even for local scroll searches it is an unfounded assumption.
The check is hence reduced to a null check for the index access.
The fact that the access control is suitable given the indices that
are actually accessed (by the scroll) will be done in a follow-up,
after we better regulate the creation of index access controls in general.
Runtime fields need to have a SearchLookup available, when building their fielddata implementations, so that they can look up other fields, runtime or not.
To achieve that, we add a Supplier<SearchLookup> argument to the existing MappedFieldType#fielddataBuilder method.
As we introduce the ability to look up other fields while building fielddata for mapped fields, we implicitly add the ability for a field to require other fields. This requires some protection mechanism that detects dependency cycles to prevent stack overflow errors.
With this commit we also introduce detection for cycles, as well as a limit on the depth of the references for a runtime field. Note that we also plan on introducing cycles detection at compile time, so the runtime cycles detection is a last resort to prevent stack overflow errors but we hope that we can reject runtime fields from being registered in the mappings when they create a cycle in their definition.
Note that this commit does not introduce any production implementation of runtime fields, but is rather a pre-requisite to merge the runtime fields feature branch.
This is a breaking change for MapperPlugins that plug in a mapper, as the signature of MappedFieldType#fielddataBuilder changes from taking a single argument (the index name), to also accept a Supplier<SearchLookup>.

Inference processors asynchronously usage write stats to the .ml-stats index after they used.
In tests the write can leak into the next test causing failures depending on which test follows.
This change waits for the usage stats docs to be written at the end of the test
If a TLS-protected connection closes unexpectedly then today we often
emit a `WARN` log, typically one of the following:
io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: Insufficient buffer remaining for AEAD cipher fragment (2). Needs to be more than tag size (16)
io.netty.handler.codec.DecoderException: javax.net.ssl.SSLException: Received close_notify during handshake
We typically only report unexpectedly-closed connections at `DEBUG`
level, but these two messages don't follow that rule and generate a lot
of noise as a result. This commit adjusts the logging to report these
two exceptions at `DEBUG` level only.
Today we use `long` to represent the number of parts of a blob. There's
no need for this extra range, it forces us to do some casting elsewhere,
and indeed when snapshotting we iterate over the parts using an `int`
which would be an infinite loop in case of overflow anyway:
for (int i = 0; i < fileInfo.numberOfParts(); i++) {
This commit changes the representation of the number of parts of a blob
to an `int`.
We convert longs to ints using `Math.toIntExact` in places where we're
sure there will be no overflow, but this doesn't explain the intent of
these conversions very well. This commit introduces a dedicated method
for these conversions, and adds an assertion that we never overflow.
If a searchable snapshot shard fails (e.g. its node leaves the cluster)
we want to be able to start it up again on a different node as quickly
as possible to avoid unnecessarily blocking or failing searches. It
isn't feasible to fully restore such shards in an acceptably short time.
In particular we would like to be able to deal with the `can_match`
phase of a search ASAP so that we can skip unnecessary waiting on shards
that may still be warming up but which are not required for the search.
This commit solves this problem by introducing a system index that holds
much of the data required to start a shard. Today(*) this means it holds
the contents of every file with size <8kB, and the first 4kB of every
other file in the shard. This system index acts as a second-level cache,
behind the first-level node-local disk cache but in front of the blob
store itself. Reading chunks from the index is slower than reading them
directly from disk, but faster than reading them from the blob store,
and is also replicated and accessible to all nodes in the cluster.
(*) the exact heuristics for what we should put into the system index
are still under investigation and may change in future.
This second-level cache is populated when we attempt to read a chunk
which is missing from both levels of cache and must therefore be read
from the blob store.
We also introduce `SearchableSnapshotsBlobStoreCacheIntegTests` which
verify that we do not hit the blob store more than necessary when
starting up a shard that we've seen before, whether due to a node
restart or because a snapshot was mounted multiple times.

If a search failure occurs during data frame extraction we catch
the error and retry once. However, we retry another search that is
identical to the first one. This means we will re-fetch any docs

an error message that the process received more records than it
expected.

The building block of the eql response is currently the SearchHit. This
is a problem since it is tied to an actual search, and thus has scoring,
highlighting, shard information and a lot of other things that are not
relevant for EQL.
This becomes a problem when doing sequence queries since the response is
not generated from one search query and thus there are no SearchHits to
speak of.
Emulating one is not just conceptually incorrect but also problematic
since most of the data is missed or made-up.
As such this PR introduces a simple class, Event, that maps nicely to
the terminology while hiding the ES internals (the use of SearchHit or
GetResult/GetResponse depending on the API used).

Report anonymous roles in response to "GET _security/_authenticate" API call when:

There are warnings about unlicense realms when user lookup fails. This PR adds
similar warnings for when no authentication token can be extracted from the request.
The API key document currently doesn't include the user's full_name or email attributes,

and in the SAML response from the [IdP Plugin](https://github.com/elastic/elasticsearch/pull/54046).
This changeset adds those fields to the document and extracts them to fill in the User when

created, but this is in line with roles and metadata as well.

Before when a value was copied to a field through a parent field or `copy_to`,
we parsed it using the `FieldMapper` from the source field. Instead we should
parse it using the target `FieldMapper`. This ensures that we apply the
appropriate mapping type and options to the copied value.
To implement the fix cleanly, this PR refactors the value parsing strategy. Now
instead of looking up values directly, field mappers produce a helper object
`ValueFetcher`. The value fetchers are responsible for almost all aspects of
fetching, including looking up the right paths in the _source.
The PR is fairly big but each commit can be reviewed individually.
Fixes#61033.
In addition, this commit converts ScaledFloatFieldMapper as it was relying
on a number of static values taken from NumberFieldMapper that had changed
or been removed.
This switches a few tests for field mappers from `ESSingleNodeTestCase`
to `ESTestCase` because, in general, we prefer to avoid
`ESSingleNodeTestCase` when we can because it is slow and "big". "Big"
here means that it pulls in an entire node, making it difficult to
reason about what you are testing.
The test didn't take into account the case where 0 documents are
indexed into the shard, meaning that files aren't loaded during
the pre-warm phase. The test injects FileSystem failures, if
the snapshot doesn't contain any files, pre-warm doesn't read
any files and the recovery completes normally.

They are passed to the native process and the native process then appends them to the

When the ML annotations index was first added, only the
ML UI wrote to it, so the code to create it was designed
with this in mind. Now the ML backend also creates
annotations, and those mappings can change between
versions.
In this change:
1. The code that runs on the master node to create the
annotations index if it doesn't exist but another ML
index does also now ensures the mappings are up-to-date.
This is good enough for the ML UI's use of the
annotations index, because the upgrade order rules say
that the whole Elasticsearch cluster must be upgraded
prior to Kibana, so the master node should be on the
newer version before Kibana tries to write an
annotation with the new fields.
2. We now also check whether the annotations index exists
with the correct mappings before starting an autodetect
process on a node. This is necessary because ML nodes
can be upgraded before the master node, so could write
an annotation with the new fields before the master node
knows about the new fields.

When a user upgrades between versions, they may stop their ML jobs.
Then when the upgrade is complete, they will want to open the jobs again.
But, when opening a job, we attempt to clear out the jobs finished_time. If the job configuration has adjusted between the versions (i.e. added a new field), it will dynamically update the .ml-config index.
We should instead manually change the mapping to be the updated version.
Fixes a test failure in which we allocated some shards and then
relocated them elsewhere, invalidating an assertion about the recovery
statistics which assumed that the shards stayed where they were
originally allocated.
Closes#61067.
This commit adds the `data_hot`, `data_warm`, `data_cold`, and `data_frozen` node roles to the
x-pack plugin. These roles are intended to be the base for the formalization of data tiers in
Elasticsearch.
These roles all act as data nodes (meaning shards can be allocated to them). Nodes with the existing
`data` role acts as though they have all of the roles configured (it is a hot, warm, cold, and
frozen node).
This also includes a custom `AllocationDecider` that allows the user to configure the following
settings on a cluster level:
- `cluster.routing.allocation.require._tier`
- `cluster.routing.allocation.include._tier`
- `cluster.routing.allocation.exclude._tier`
And in index settings:
- `index.routing.allocation.require._tier`
- `index.routing.allocation.include._tier`
- `index.routing.allocation.exclude._tier`

Today a snapshot repository verification ensures that all master-eligible and data nodes have write access to the
snapshot repository (and can see each other's data) since taking a snapshot requires data nodes and the currently
elected master to write to the repository. However, a dedicated voting-only master-eligible node is not a data node and
will never be the elected master so we should not require it to have write access to the repository.

Use thread-local buffers and deflater and inflater instances to speed up
compressing and decompressing from in-memory bytes.
Not manually invoking `end()` on these should be safe since their off-heap memory
will eventually be reclaimed by the finalizer thread which should not be an issue for thread-locals
that are not instantiated at a high frequency.
This significantly reduces the amount of byte copying and object creation relative to the previous approach
which had to create a fresh temporary buffer (that was then resized multiple times during operations), copied
bytes out of that buffer to a freshly allocated `byte[]`, used 4k stream buffers needlessly when working with
bytes that are already in arrays (`writeTo` handles efficient writing to the compression logic now) etc.

This pull request adds recovery state tracking for Searchable Snapshots.
In order to track recoveries for searchable snapshot backed indices, this pull
request adds a new type of RecoveryState.
This newRecoveryState instance is able to deal with the
small differences that arise during Searchable snapshots recoveries.
Those differences can be summarized as follows:
- The Directory implementation that's provided by SearchableSnapshots mark the
snapshot files as reused during recovery. In order to keep track of the
recovery process as the cache is pre-warmed, those files shouldn't be marked
as reused.
- Once the shard is created, the cache starts its pre-warming phase, meaning that
we should keep track of those downloads during that process and tie the recovery
to this pre-warming phase. The shard is considered recovered once this pre-warming
phase has finished.

Currently, validation of mappers (checking that cross-references are correct, limits on
field name lengths and object depths, multiple definitions, etc) is performed by the
MapperService. This means that any mapper-specific validation, for example that done
on the CompletionFieldMapper, needs to be called specifically from core server code,
and so we can't add validation to mappers that live in plugins.
This commit reworks the validation framework so that mapper-specific validation is
done on the Mapper itself. Mapper gets a new `validate(MappingLookup)`
method (already present on `MetadataFieldMapper` and now pulled up to the parent
interface), which is called from a new `DocumentMapper.validate()` method. All
the validation code currently living on `MapperService` moves either to individual
mapper implementations (FieldAliasMapper, CompletionFieldMapper) or into
`MappingLookup`, an altered `DocumentFieldMappers` which now knows about
object fields and can check for duplicate definitions, or into DocumentMapper
which handles soft limit checks.

This commit adds compatibility testing of our JDBC driver against
different Elasticsearch versions. Although we are really testing the
forwards compatibility nature of the JDBC driver we model the testing
the same as we do existing BWC tests, that is, with the current branch
fetching the earlier versions of the artifact that is to be tested. In
this case, that's the JDBC driver itself.
Because the tests include the JDBC driver jar on it's classpath we had
to change the packaging of the driver jar in order to avoid jarhell and
other conflicting dependency issues when using an old JDBC driver with
later branches. For this we simply relocate all driver dependencies in
the shadow jar under a "shadowed" package. This allows the JDBC driver
to use the correct version of Elasticsearch libs classes, while the
tests themselves use their versions. Since this required a change to the
driver jar compatibility testing can only go back as far as that version
which at the time of this commit is 7.8.1.
Prior to this change ML memory estimation processes for a
given job would always use the same named pipe names. This

Due to complicated access checks (reads and writes execute in their own access context) on some repositories (GCS, Azure, HDFS), using a hard coded buffer size of 4k for restores was needlessly inefficient.
By the same token, the use of stream copying with the default 8k buffer size for blob writes was inefficient as well.
We also had dedicated, undocumented buffer size settings for HDFS and FS repositories. For these two we would use a 100k buffer by default. We did not have such a setting for e.g. GCS though, which would only use an 8k read buffer which is needlessly small for reading from a raw `URLConnection`.
This commit adds an undocumented setting that sets the default buffer size to `128k` for all repositories. It removes wasteful allocation of such a large buffer for small writes and reads in case of HDFS and FS repositories (i.e. still using the smaller buffer to write metadata) but uses a large buffer for doing restores and uploading segment blobs.
This should speed up Azure and GCS restores and snapshots in a non-trivial way as well as save some memory when reading small blobs on FS and HFDS repositories.
This commit continues on the work in #59801 and makes other
implementors of the LocalNodeMasterListener interface thread safe in
that they will no longer allow the callbacks to run on different
threads and possibly race each other. This also helps address other
issues where these events could be queued to wait for execution while
the service keeps moving forward thinking it is the master even when
that is not the case.
In order to accomplish this, the LocalNodeMasterListener no longer has
the executorName() method to prevent future uses that could encounter
this surprising behavior.
Each use was inspected and if the class was also a
ClusterStateListener, the implementation of LocalNodeMasterListener
was removed in favor of a single listener that combined the logic. A
single listener is used and there is currently no guarantee on execution
order between ClusterStateListeners and LocalNodeMasterListeners,
so a future change there could cause undesired consequences. For other
classes, the implementations of the callbacks were inspected and if the
operations were lightweight, the overriden executorName method was
removed to use the default, which runs on the same thread.

In #58877, when we switched test inference on java, we just

features during inference the same way they are extracted
in `DataFrameDataExtractor` when they are used for training.

If shard level results are incomplete in the data streams stats call, it is possible to get inaccurate
counts of the number of backing indices, despite this data being accurate and available in the
cluster state.
This PR removes the expand_wildcards and forbid_closed_indices parameters from the Data
Streams Stats REST endpoint. These options are required for broadcast requests, but are not
needed for anything in terms of resolving data streams. Instead, we just set a default set of
IndicesOptions on the transport request.
This test failed by hitting the 10s default busy assert timeout.
Given how involved the retention run is (multiple disk reads, CS updates etc.)
we should have a higher timeout here.
Also, removed the pointless delete call for the snapshot that we just asserted is gone,
at the end of the test.

We never used the `IndexSettings` parameter and we only used the

This PR further reduces the memory footprint of the
testGeoHashGridCircuitBreaker test such that only
0.26% of the randomized runs result in memory usage of between

> 50mb of memory resulting in OOMs in CI
Closes#59853.
This change fixes two possible race conditions in SLM related to
how local master changes and cluster state events are observed. When
implementing the `LocalNodeMasterListener` interface, it is only
recommended to execute on a separate threadpool if the operations are
heavy and would block the cluster state thread. SLM specified that the
listeners should run in the Snapshot thread pool, but the operations
in the listener were lightweight. This had the side effect of causing
master changes to be delayed if the Snapshot threads were all busy and
could also potentially cause the `onMaster` and `offMaster` calls to
race if both were queued and then executed concurrently. Additionally,
the `SnapshotLifecycleService` is also a `ClusterStateListener` and
there is currently no order of operations guarantee between
`LocalNodeMasterListeners` and `ClusterStateListeners` so this could
lead to incorrect behavior.
The resolution for these two issues is that the
SnapshotRetentionService now specifies the `SAME` executor for its
implementation of the `LocalNodeMasterListener` interface. The
`SnapshotLifecycleService` is no longer a `LocalNodeMasterListener` and
instead tracks local master changes in its `ClusterStateListner`.
Backport of #59801
The submit async search action should not populate the thread context
DLS/FLS permission set, because it is not currently authorised as an "indices request"
and hence the permission set that it builds is incomplete and it overrides the
DLS/FLS permission set of the actual spawned search request (which is built correctly).
When dealing with tail queries, data is returned descending for the base
criterion yet the rest of the queries are ascending. This caused a
problem during insertion since while in a page, the data is ASC, between
pages the blocks of data is DESC.
This caused incorrectly sorting inside a SequenceGroup which led to
incorrect results.
Further more in case of limit, since the data in a page is ASC, early
return is not possible neither is desc matching. Thus the page needs to
be consumed first before finding the final results.
A future improvement could be to keep only the top N results dropping
the rest during insertion time.

* Adding new `require_alias` option to indexing requests (#58917)
This commit adds the `require_alias` flag to requests that create new documents.
This flag, when `true` prevents the request from automatically creating an index. Instead, the destination of the request MUST be an alias.
When the flag is not set, or `false`, the behavior defaults to the `action.auto_create_index` settings.
This is useful when an alias is required instead of a concrete index.

* [ML] add new `custom` field to trained model processors (#59542)
This commit adds the new configurable field `custom`.
`custom` indicates if the preprocessor was submitted by a user or automatically created by the analytics job.
Eventually, this field will be used in calculating feature importance. When `custom` is true, the feature importance for
the processed fields is calculated. When `false` the current behavior is the same (we calculate the importance for the originating field/feature).
This also adds new required methods to the preprocessor interface. If users are to supply their own preprocessors

Previously the concrete type parameters for the MappedFieldType didn't always
match those for the FieldMapper. This PR updates the mappers so that the type
parameters always match, which makes the design easier to follow.
to avoid many error stacktraces in logs during a rolling upgrade.
Stack templates use the composable index template and component APIs,these APIs
aren't supported in 7.7 and earlier and in mixed cluster
environments this can cause a lot of ActionNotFoundTransportException
errors in the logs during rolling upgrades. If these templates
are only installed via elected master node then the APIs are always
there and the ActionNotFoundTransportException errors are then prevented.
When an inference model is loaded it is accounted for in circuit breaker
and should not be released until there are no users of the model. Adds
a reference count to the model to track usage.
Today when mounting a searchable snapshot we obtain the snapshot/index
UUIDs and then assume that these are the UUIDs used during the
subsequent restore. If you concurrently delete the snapshot and replace
it with one with the same name then this assumption is violated, with
chaotic consequences.
This commit introduces a check that ensures that the snapshot UUID does
not change during the mount process. If the snapshot remains in place
then the index UUID necessarily does not change either.

Since #58728 writing operations on searchable snapshot directory cache files
are executed in an asynchronous manner using a dedicated thread pool. The
thread pool used is searchable_snapshots which has been created to execute
prewarming tasks.
Reusing the same thread pool wasn't a good idea as it can lead to deadlock
situations. One of these situation arose in a test failure where the thread pool
was full of prewarming tasks, all waiting for a cache file to be accessible, while
the cache file was being evicted by the cache service. But such an eviction
can only be processed when all read/write operations on the cache file are
completed and in this case the deadlock occurred because the cache file was
actively being read by a concurrent search which also won the privilege to
write the range of bytes in cache... and this writing operation could never have
been completed because of the prewarming tasks making no progress and
filling up the thread pool.
This commit renames the searchable_snapshots thread pool to
searchable_snapshots_cache_fetch_async. Assertions are added to assert
that cache writes are executed using this thread pool and to assert that read
on cached index inputs are executed using a different thread pool to avoid
potential deadlock situations.
This commit also adds a searchable_snapshots_cache_prewarming that is
used to execute prewarming tasks. It also converts the existing cache prewarming
test into a more complte integration test that creates multiple searchable
snapshot indices concurrently with randomized thread pool sizes, and verifies
that all files have been correctly prewarmed.

Enables fully concurrent snapshot operations:
* Snapshot create- and delete operations can be started in any order
* Delete operations wait for snapshot finalization to finish, are batched as much as possible to improve efficiency and once enqueued in the cluster state prevent new snapshots from starting on data nodes until executed
* We could be even more concurrent here in a follow-up by interleaving deletes and snapshots on a per-shard level. I decided not to do this for now since it seemed not worth the added complexity yet. Due to batching+deduplicating of deletes the pain of having a delete stuck behind a long -running snapshot seemed manageable (dropped client connections + resulting retries don't cause issues due to deduplication of delete jobs, batching of deletes allows enqueuing more and more deletes even if a snapshot blocks for a long time that will all be executed in essentially constant time (due to bulk snapshot deletion, deleting multiple snapshots is mostly about as fast as deleting a single one))
* Snapshot creation is completely concurrent across shards, but per shard snapshots are linearized for each repository as are snapshot finalizations
See updated JavaDoc and added test cases for more details and illustration on the functionality.
Some notes:
The queuing of snapshot finalizations and deletes and the related locking/synchronization is a little awkward in this version but can be much simplified with some refactoring. The problem is that snapshot finalizations resolve their listeners on the `SNAPSHOT` pool while deletes resolve the listener on the master update thread. With some refactoring both of these could be moved to the master update thread, effectively removing the need for any synchronization around the `SnapshotService` state. I didn't do this refactoring here because it's a fairly large change and not necessary for the functionality but plan to do so in a follow-up.
This change allows for completely removing any trickery around synchronizing deletes and snapshots from SLM and 100% does away with SLM errors from collisions between deletes and snapshots.
Snapshotting a single index in parallel to a long running full backup will execute without having to wait for the long running backup as required by the ILM/SLM use case of moving indices to "snapshot tier". Finalizations are linearized but ordered according to which snapshot saw all of its shards complete first
There is no point in writing out snapshots that contain no data that can be restored
whatsoever. It may have made sense to do so in the past when there was an `INIT` snapshot
step that wrote data to the repository that would've other become unreferenced, but in the
current day state machine without the `INIT` step there is no point in doing so.
Many of the parameters we pass into this method were only used to
build the `SnapshotInfo` instance to write.
This change simplifies the signature. Also, it seems less error prone to build
`SnapshotInfo` in `SnapshotsService` isntead of relying on the fact that each repository
implementation will build the correct `SnapshotInfo`.
This commit adds a new api to track when gold+ features are used within
x-pack. The tracking is done internally whenever a feature is checked
against the current license. The output of the api is a list of each
used feature, which includes the name, license level, and last time it
was used. In addition to a unit test for the tracking, a rest test is
added which ensures starting up a default configured node does not
result in any features registering as used.
There are a couple features which currently do not work well with the
tracking, as they are checked in a manner that makes them look always
used. Those features will be fixed in followups, and in this PR they are
omitted from the feature usage output.

API keys can be created nameless using the grant endpoint (it is a bug, see #59484).
This change ensures auditing doesn't throw when such an API Key is used for authn.
The `create_doc`, `create`, `write` and `index` privileges do not grant
the PutMapping action anymore. Apart from the `write` privilege, the other
three privileges also do NOT grant (auto) updating the mapping when ingesting
a document with unmapped fields, according to the templates.
In order to maintain the BWC in the 7.x releases, the above privileges will still grant
the Put and AutoPutMapping actions, but only when the "index" entity is an alias
or a concrete index, but not a data stream or a backing index of a data stream.
This PR introduces two new fields in to `RepositoryData` (index-N) to track the blob name of `IndexMetaData` blobs and their content via setting generations and uuids. This is used to deduplicate the `IndexMetaData` blobs (`meta-{uuid}.dat` in the indices folders under `/indices` so that new metadata for an index is only written to the repository during a snapshot if that same metadata can't be found in another snapshot.
This saves one write per index in the common case of unchanged metadata thus saving cost and making snapshot finalization drastically faster if many indices are being snapshotted at the same time.
The implementation is mostly analogous to that for shard generations in #46250 and piggy backs on the BwC mechanism introduced in that PR (which means this PR needs adjustments if it doesn't go into `7.6`).
Relates to #45736 as it improves the efficiency of snapshotting unchanged indices
Relates to #49800 as it has the potential of loading the index metadata for multiple snapshots of the same index concurrently much more efficient speeding up future concurrent snapshot delete
Currently we combine coordinating and primary bytes into a single bucket

However, for metrics it would be useful to separate them.
The `Authentication` object that gets built following an API Key authentication

throw an NPE, because the owner realm name is not found in the expected field.

When a field is not included yet its type is unsupported, we currently

be including a field with unsupported type.
This commit improves this by stating the reason a not included field

Certain OPs mix usage of boolean and string for boolean type OIDC claims. For example, the same "email_verified" field is presented as boolean in IdToken, but is a string of "true" in the response of user info. This inconsistency results in failures when we try to merge them during authorization.
This PR introduce a small leniency so that it will merge a boolean with a string that has value of the boolean's string representation. In another word, it will merge true with "true", also will merge false with "false", but nothing else.
This adds a low precendece mapping for the `@timestamp` field with
type `date`.
This will aid with the bootstrapping of data streams as a timestamp
mapping can be omitted when nanos precision is not needed.

* Create new data-stream xpack module.
* Move TimestampFieldMapper to the new module,
this results in storing a composable index template
with data stream definition only to work with default
distribution. This way data streams can only be used
with default distribution, since a data stream can
currently only be created if a matching composable index
template exists with a data stream definition.
* Renamed `_timestamp` meta field mapper
to `_data_stream_timestamp` meta field mapper.
* Add logic to put composable index template api
to fail if `_data_stream_timestamp` meta field mapper
isn't registered. So that a more understandable
error is returned when attempting to store a template
with data stream definition via the oss distribution.
In a follow up the data stream transport and
rest actions can be moved to the xpack data-stream module.
With the introduction of per-partition categorization the old
logic for creating a job notification for categorization status
"warn" does not work. However, the C++ code is already writing
annotations for categorization status "warn" that take into
account whether per-partition categorization is being used and
which partition(s) the warnings relate to. Therefore, this
change alters the Java results processor to create notifications
based on the annotations the C++ writes. (It is arguable that
we don't need both annotations and notifications, but they show
up in different ways in the UI: only annotations are visible in
results and only notifications set the warning symbol in the
jobs list. This means it's best to have both.)

This PR ensure that same roles are cached only once even when they are from different API keys.
API key role descriptors and limited role descriptors are now saved in Authentication#metadata
as raw bytes instead of deserialised Map<String, Object>.
Hashes of these bytes are used as keys for API key roles. Only when the required role is not found
in the cache, they will be deserialised to build the RoleDescriptors. The deserialisation is directly
from raw bytes to RoleDescriptors without going through the current detour of
"bytes -> Map -> bytes -> RoleDescriptors".
With the removal of mapping types and the immutability of FieldTypeLookup in #58162, we no longer
have any cause to compare MappedFieldType instances. This means that we can remove all equals
and hashCode implementations, and in addition we no longer need the clone implementations which
were required for equals/hashcode testing. This greatly simplifies implementing new MappedFieldTypes,
which will be particularly useful for the runtime fields project.
This adds a setting to data frame analytics jobs called
`max_number_threads`. The setting expects a positive integer.
When used the user specifies the max number of threads that may
be used by the analysis. Note that the actual number of threads
used is limited by the number of processors on the node where
the job is assigned. Also, the process may use a couple more threads
for operational functionality that is not the analysis itself.
This setting may also be updated for a stopped job.
More threads may reduce the time it takes to complete the job at the cost
of using more CPU.

The FieldMapper infrastructure currently has a bunch of shared parameters, many of which
are only applicable to a subset of the 41 mapper implementations we ship with. Merging,
parsing and serialization of these parameters are spread around the class hierarchy, with
much repetitive boilerplate code required. It would be much easier to reason about these
things if we could declare the parameter set of each FieldMapper directly in the implementing
class, and share the parsing, merging and serialization logic instead.
This commit is a first effort at introducing a declarative parameter style. It adds a new FieldMapper
subclass, ParametrizedFieldMapper, and refactors two mappers, Boolean and Binary, to use it.
Parameters are declared on Builder classes, with the declaration including the parameter name,
whether or not it is updateable, a default value, how to parse it from mappings, and how to
extract it from another mapper at merge time. Builders have a getParameters method, which
returns a list of the declared parameters; this is then used for parsing, merging and serialization.
Merging is achieved by constructing a new Builder from the existing Mapper, and merging in
values from the merging Mapper; conflicts are all caught at this point, and if none exist then a new,
merged, Mapper can be built from the Builder. This allows all values on the Mapper to be final.
Other mappers can be gradually migrated to this new style, and once they have all been refactored
we can merge ParametrizedFieldMapper and FieldMapper entirely.

are present only when authn using an API Key.
2. When authn with an API Key, the `user.realm` field now contains the effective
realm name of the user that created the key, instead of the synthetic value of
`_es_api_key`.

* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and

* Fixed a bug (#58956) that cases timestamp field validation to be performed
for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

Today we empty the searchable snapshots cache when cleanly closing a
shard, but leak cache files in some cases involving an unclean shutdown.
Such leaks are not permanent, they are cleaned up on shard relocation or
deletion, but they still might last for arbitrarily long until that
happens. This commit introduces a cleanup process that runs during node
startup to catch such leaks sooner.
Also, today we permit searchable snapshots to be held on custom data
paths, and store the corresponding cache files within the custom
location. Supporting this feature would make the cleanup process
significantly more complicated since it would require each node to parse
the index metadata for the shards it held before shutdown. Yet, this
feature is undocumented and offers minimal benefits to searchable
snapshots. Therefore with this commit we forbid custom data paths for
searchable snapshot shards.
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.

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.
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.

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 have been affected by this problem (state and stats) wait for
the shards to be initialized before returning.

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

The current internal sequence algorithm relies on fetching multiple results and then paginating through the dataset. Depending on the dataset and memory, setting a larger page size can yield better performance at the expense of memory.
This PR makes this behavior explicit by decoupling the fetch size from size, the maximum number of results desired.
As such, use in testing a minimum fetch size which exposed a number of bugs:
Jumping across data across queries causing valid data to be seen as a gap.
Incorrectly resuming searching across pages (again causing data to be discarded).
which have been addressed.

The PR introduces following two changes:
Move API key validation into a new separate threadpool. The new threadpool is created separately with half of the available processors and 1000 in queue size. We could combine it with the existing TokenService's threadpool. Technically it is straightforward, but I am not sure whether it could be a rushed optimization since I am not clear about potential impact on the token service.
On threadpoool saturation, it now fails with EsRejectedExecutionException which in turns gives back a 429, instead of 401 status code to users.
Backport of #58582 to 7.x branch.
This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.
The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

Dry up tests that use a disruption that isolates the master from all other nodes.
Also, turn disruption types that have neither parameters nor state into constants
to make things a little clearer.
This commit changes our behavior in 2 ways:
- When mapping claims to user properties ( principal, email, groups,
name), we only handle string and array of string type. Previously
we would fail to recognize an array of other types and that would
cause failures when trying to cast to String.
- When adding unmapped claims to the user metadata, we only handle
string, number, boolean and arrays of these. Previously, we would
fail to recognize an array of other types and that would cause
failures when attempting to process role mappings.
For user properties that are inherently single valued, like
principal(username) we continue to support arrays of strings where
we select the first one in case this is being depended on by users
but we plan on removing this leniency in the next major release.

Despite all my attempts I did not manage to reproduce issues like the ones
described in #58961. My guess is that the _mount request got retried at
some point but I wasn't able to validate this assumption.
Still, the FsSearchableSnapshotsIT can be pretty disk heavy if a small
random chunk size and a large number of documents is picked up in the
tests. The parent class also does not verify the acknowledged status
of some requests.
This commit lowers down the chunk size and number of docs in tests
(this is extensively tests in unit tests) and also adds assertions on
acknowledged responses.

Working through a heap dump for an unrelated issue I found that we can easily rack up
tens of MBs of duplicate empty instances in some cases.
I moved to a static constructor to guard against that in all cases.
* SQL: Redact credentials in connection exceptions (#58650)
This commit adds the functionality to redact the credentials from the
exceptions generated when a connection attempt fails, preventing them
from leaking into logs, console history etc.
There are a few causes that can lead to failed connections. The most
challenging to deal with is a malformed connection string. The redaction
tries to get around it by modifying the URI to a parsable state, so that
the redaction can be applied reliably. If there's no reliability
guarantee, the redaction will bluntly replace the entire connection
string and the user informed about the option to modify it so that the
redaction won't apply. (This is done by using a caplitalized scheme,
which is legal, but otherwise never used in practice.)
The commit fixes a couple of other issues with the URI parser:
- it allows an empty hostname, or even entire connection string (as per
the existing documentation);
- it reduces the editing of the connection string in the exception
messages (so that the user easier recognize their input);
- it uses the default URI as source for the scheme and hostname.

SQL: fix handling of escaped chars in JDBC connection string (#58429)
This commit fixes an issue emerging when the connection string URI
contains escaped characters.
The original URI is pre-parsed in order to re-assemble a new URI having
the optional elements filled in with defaults. The new URI has been
using however the unescaped query and fragment parts. So if these
contained any escaped `&` or `=` (such as in the password option value),
the unescaping would reveal them and make them later interfere with the
options parsing.
The commit changes that, so that the new URI be built from the unescaped
"raw" parts of the original URI.

- The exception that we caught when failing to schedule a thread was incorrect.
- We may have failures when reducing the response before returning it, which were not handled correctly and may have caused get or submit async search task to not be properly unregistered from the task manager
- when the completion listener onFailure method is invoked, the search task has to be unregistered. Not doing so may cause the search task to be stuck in the task manager although it has completed.

.ml-state-write is supposed to be an index alias, however by accident it can become an index. If
.ml-state-write is a concrete index instead of an alias ML stops working. This change improves error
handling by setting the job to failed and properly log and audit the problem. The user still has to
manually fix the problem. This change should lead to a quicker resolution of the problem.
fixes#58482
When we execute search against remote indices, the remote indices are authorized on the remote cluster and not on the CCS cluster. When we introduced submit async search we added a check that requires that the user running it has the privilege to execute it on some index. That prevents users from executing async searches against remote indices unless they also have read access on the CCS cluster, which is common when the CCS cluster holds no data.
The solution is to let the submit async search go through as we already do for get and delete async search. Note that the inner search action will still check that the user can access local indices, and remote indices on the remote cluster, like search always does.
The Saml SP document stored the role mapping in a Set, but this made
the order in XContent inconsistent. This switched it to use a TreeSet.

This is a follow-up to #57573. This commit combines coordinating and
primary bytes under the same "write" bucket. Double accounting is
prevented by only accounting the bytes at either the reroute phase or
the primary phase. TransportBulkAction calls execute directly, so the
operations handler is skipped and the bytes are not double accounted.
A regression in the mapping code led to geo_shape no longer supporting
array-valued fields. This commit fixes this support and adds an integration
test to make sure this problem does not return!
We already had code to ensure the config index mappings were
up-to-date before creating a new config. However, it's also
possible that an update to a config could add the latest
settings that require the latest mappings to index correctly.
This change checks that the latest config index mappings are
in place in the 3 update actions in the same way as the checks
are done in the 3 put actions.

Add caching support for application privileges to reduce number of round-trips to security index when building application privilege descriptors.
Privilege retrieving in NativePrivilegeStore is changed to always fetching all privilege documents for a given application. The caching is applied to all places including "get privilege", "has privileges" APIs and CompositeRolesStore (for authentication).
* [ML] handles compressed model stream from native process (#58009)
This moves model storage from handling the fully parsed JSON string to handling two separate types of documents.
1. ModelSizeInfo which contains model size information
2. TrainedModelDefinitionChunk which contains a particular chunk of the compressed model definition string.
`model_size_info` is assumed to be handled first. This will generate the model_id and store the initial trained model config object. Then each chunk is assumed to be in correct order for concatenating the chunks to get a compressed definition.
Native side change: https://github.com/elastic/ml-cpp/pull/1349
When the documents are large, a follower can receive a partial response
because the requesting range of operations is capped by
max_read_request_size instead of max_read_request_operation_count. In
this case, the follower will continue reading the subsequent ranges
without checking the remaining size of the buffer. The buffer then can
use more memory than max_write_buffer_size and even causes OOM.

Since #58728 part of searchable snapshot shard files are written in cache
in an asynchronous manner in a dedicated thread pool. It means that even
if a search query is successful and returns, there are still more bytes to
write in the cached files on disk.
On CI this can be slow; if we want to check that the cached_bytes_written
has changed we need to check multiple times to give some time for the
cached data to be effectively written.
The checks on the license state have a singular method, isAllowed, that
returns whether the given feature is allowed by the current license.
However, there are two classes of usages, one which intends to actually
use a feature, and another that intends to return in telemetry whether
the feature is allowed. When feature usage tracking is added, the latter
case should not count as a "usage", so this commit reworks the calls to
isAllowed into 2 methods, checkFeature, which will (eventually) both
check whether a feature is allowed, and keep track of the last usage
time, and isAllowed, which simply determines whether the feature is
allowed.
Note that I considered having a boolean flag on the current method, but
wanted the additional clarity that a different method name provides,
versus a boolean flag which is more easily copied without realizing what
the flag means since it is nameless in call sites.
This commit changes CacheFile and CachedBlobContainerIndexInput so that
the read operations made by these classes are now progressively executed
and do not wait for full range to be written in cache. It relies on the change
introduced in #58477 and it is the last change extracted from #58164.

Restoring from a snapshot (which is a particular form of recovery) does not currently take recovery throttling into account
(i.e. the `indices.recovery.max_bytes_per_sec` setting). While restores are subject to their own throttling (repository
setting `max_restore_bytes_per_sec`), this repository setting does not allow for values to be configured differently on a
per-node basis. As restores are very similar in nature to peer recoveries (streaming bytes to the node), it makes sense to
configure throttling in a single place.
The `max_restore_bytes_per_sec` setting is also changed to default to unlimited now, whereas previously it was set to
`40mb`, which is the current default of `indices.recovery.max_bytes_per_sec`). This means that no behavioral change
will be observed by clusters where the recovery and restore settings were not adapted.

Today the disk-based shard allocator accounts for incoming shards by
subtracting the estimated size of the incoming shard from the free space on the
node. This is an overly conservative estimate if the incoming shard has almost
finished its recovery since in that case it is already consuming most of the
disk space it needs.
This change adds to the shard stats a measure of how much larger each store is
expected to grow, computed from the ongoing recovery, and uses this to account
for the disk usage of incoming shards more accurately.

* Picky picky
* Missing type
SAML idP sends back a LogoutResponse at the end of the logout workflow. It can be sent via either HTTP-Redirect binding or HTTP-POST binding. Currently, the HTTP-Redirect request is simply ignored by Kibana and never reaches ES. It does not cause any obvious issue and the workflow is completed normally from user's perspective.
The HTTP-POST request results in a 404 error because POST request is not accepted by Kibana's logout end-point. This causes a non-trivial issue because it renders an error page in user's browser. In addition, some resources do not seem to be fully cleaned up due to the error, e.g. the username will be pre-filled when trying to login again after the 404 error.
This PR solves both of the above issues from ES side with a new /_security/saml/complete_logout end-point. Changes are still needed on Kibana side to relay the messages.

Mapping updates that originate from indexing a document with unmapped fields will use this new action
instead of the current put mapping action. This way on the security side, authorization logic
can easily determine whether a mapping update is automatically generated or a mapping update originates
from the put mapping api.
The new auto put mapping action is only used if all nodes are on the version that supports it.
This PR implements recursive mapping merging for composable index templates.
When creating an index, we perform the following:
* Add each component template mapping in order, merging each one in after the
last.
* Merge in the index template mappings (if present).
* Merge in the mappings on the index request itself (if present).
Some principles:
* All 'structural' changes are disallowed (but everything else is fine). An
object mapper can never be changed between `type: object` and `type: nested`. A
field mapper can never be changed to an object mapper, and vice versa.
* Generally, each section is merged recursively. This includes `object`
mappings, as well as root options like `dynamic_templates` and `meta`. Once we
reach 'leaf components' like field definitions, they always overwrite an
existing one instead of being merged.

RandomZone test method returns a ZoneId from the set of ids supported by
java. The only difference between joda and java supported timezones are
SystemV* timezones.
These should be excluded from randomZone method as they would break
testing. They also do not bring much confidence when used in testing as
I suspect they are rarely used.
That exclude should be removed for simplification once joda support is removed.
This commit adds the BuildParams.testSeed to the repository base paths used
in searchable snapshots QA tests. For S3 and GCS the test seed is added for
coherency sake with other integration tests while it's required for Azure as
Azure 3rd party tests are executed on CI simultaneously for regular and
SAS token accounts.
Closes#58260
The GET /_license endpoint displays "enterprise" licenses as
"platinum" by default so that old clients (including beats, kibana and
logstash) know to interpret this new license type as if it were a
platinum license.
However, this compatibility layer was not applied to the GET /_xpack/
endpoint which also displays a license type & mode.
This commit causes the _xpack API to mimic the _license API and treat
enterprise as platinum by default, with a new accept_enterprise
parameter that will cause the API to return the correct "enterprise"
value.
This BWC layer exists only for the 7.x branch.
This is a breaking change because, since 7.6, the _xpack API has
returned "enterprise" for enterprise licenses, but this has been found
to break old versions of beats and logstash so needs to be corrected.
EQL sequences can specify now a maximum time allowed for their span
