When a tree model is provided, it is possible that it is a stump.
Meaning, it only has one node with no splits
This implies that the tree has no features. In this case,
having zero feature_names is appropriate. In any other case,
this should be considered a validation failure.
This commit adds the validation if there is more than 1 node,
that the feature_names in the model are non-empty.

Fetch failures are currently tracked byy AsyncSearchTask like ordinary shard failures. Though they should be treated differently or they end up causing weird scenarios like total=num_shards and successful=num_shards as the query phase ran fine yet the failed count would reflect the number of shards where fetch failed.
Given that partial results only include aggs for now and are complete even if fetch fails, we can ignore fetch failures in async search, as they will be anyways included in the response. They are in fact either received as a failure when all shards fail during fetch, or as part of the final response when only some shards fail during fetch.
Currently, the async search task is the task that will be running through the whole execution of an async search. While the submit async search task prints out the search as part of its description, async search task doesn't while it should.
With this commit we address that while also making sure that the description highlights that the task is originated from an async search.
Also, we streamline the way the description is printed out by SearchTask so that it does not get forgotten in the future.
Wildcard field bug fix for term and prefix queries.
We now escape any * or ? characters in the search string before delegating to the main wildcardQuery() method.

In many cases we don't need a `StreamInput` or `StreamOutput`
wrapper around these streams so I this commit adjusts the API
to just normal streams and adds the wrapping where necessary.
Since join keys are common across all queries in a Join/Sequence, any
constraint applied on one query needs to be obeyed but all the other
queries.
This PR enhances the optimizer to propagate such constraints across
all queries so they get pushed down to the actual generated ES queries.

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.

When a user authenticates via OpenID Connect we copy information from

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.
Closes#60828
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.

For 1/2 the plugins in x-pack, the integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.
This includes the following projects:
security, spatial, stack, transform, vecotrs, voting-only-node, and watcher.
A few of the more specialized qa projects within these plugins
have not been changed with this PR due to additional complexity which should

While starting the data frame analytics process it is possible
to get an exception before the process crash handler is in place.
In addition, right after starting the process, we check the process
is alive to ensure we capture a failed process. However, those exceptions
are unhandled.
This commit catches any exception thrown while starting the process
and sets the task to failed with the root cause error message.
I have also taken the chance to remove some unused parameters
in `NativeAnalyticsProcessFactory`.
