Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
Added an integration test to validate behaviour of string scalars on top
of aggregate functions. The behaviour was fixed with #49570.

(cherry picked from commit 35f964154850e3f02b6c7f9ca238da98ad83ebb3)
Simplify the code by removing the generic type from InferenceConfigUpdate which
meant wildcard types were used in many places. Instead check the class type is
appropriate where used.
* [DOCS] Reformat `flatten_graph` token filter
Makes the following changes to the `flatten_graph` token filter docs:
* Rewrites description and adds Lucene link
* Adds detailed analyze example
* Adds analyzer example
Today the voting config exclusions API accepts node filters and resolves them
to a collection of node IDs against the current cluster membership.
This is problematic since we may want to exclude nodes that are not currently
members of the cluster. For instance:
- if attempting to remove a flaky node from the cluster you cannot reliably
exclude it from the voting configuration since it may not reliably be a
member of the cluster
- if `cluster.auto_shrink_voting_configuration: false` then naively shrinking
the cluster will remove some nodes but will leaving their node IDs in the
voting configuration. The only way to clean up the voting configuration is to
grow the cluster back to its original size (potentially replacing some of the
voting configuration) and then use the exclusions API.
This commit adds an alternative API that accepts node names and node IDs but
not node filters in general, and deprecates the current node-filters-based API.

This commit fixes our behavior regarding the responses we
return in various cases for the use of token related APIs.
More concretely:
- In the Get Token API with the `refresh` grant, when an invalid
(already deleted, malformed, unknown) refresh token is used in the
body of the request, we respond with `400` HTTP status code
and an `error_description` header with the message "could not
refresh the requested token".
Previously we would return erroneously return a `401` with "token
malformed" message.
- In the Invalidate Token API, when using an invalid (already
deleted, malformed, unknown) access or refresh token, we respond
with `404` and a body that shows that no tokens were invalidated:
```
{
"invalidated_tokens":0,
"previously_invalidated_tokens":0,
"error_count":0
}
```
The previous behavior would be to erroneously return
a `400` or `401` ( depending on the case ).
- In the Invalidate Token API, when the tokens index doesn't
exist or is closed, we return `400` because we assume this is
a user issue either because they tried to invalidate a token
when there is no tokens index yet ( i.e. no tokens have
been created yet or the tokens index has been deleted ) or the
index is closed.
- In the Invalidate Token API, when the tokens index is
unavailable, we return a `503` status code because
we want to signal to the caller of the API that the token they
tried to invalidate was not invalidated and we can't be sure
if it is still valid or not, and that they should try the request
again.
Resolves: #53323
When a datafeed transitions from lookback to real-time we request
that state is persisted from the autodetect process in the
background.
This PR adds a test to prove that for a categorization job the
state that is persisted includes the categorization state.
Without the fix from elastic/ml-cpp#1137 this test fails. After
that C++ fix is merged this test should pass.
Backport of #55243
After #54650 we catch `TaskCancelledException` when we wait for
reindexing to complete as it may be thrown. However, when that happens
we do not mark the task as completed. This results in the stop request
never returning and the failures we saw in #55068.
Closes#55068
Backport of #55286
Following elastic/ml-cpp#1135 there are now Linux binaries
for both x86_64 and aarch64. The code that finds the
correct binaries to ship with each distribution was
including both on every Linux distribution. This change
alters that logic to consider the architecture as well
as the operating system.
Also, there is no need to disable ML on aarch64 now that
we have the native binaries available. ML is still not
supported on aarch64, but the processes at least run up
and work at a superficial level.
Backport of #55256
The ResourceWatcherService enables watching of files for modifications
and deletions. During startup various consumers register the files that
should be watched by this service. There is behavior that might be
unexpected in that the service may not start polling until later in the
startup process due to the use of lifecycle states to control when the
service actually starts the jobs to monitor resources. This change
removes this unexpected behavior so that upon construction the service
has already registered its tasks to poll resources for changes. In
making this modification, the service no longer extends
AbstractLifecycleComponent and instead implements the Closeable
interface so that the polling jobs can be terminated when the service
is no longer required.

Today we indiscriminately serialize these independent of the version on
the stream, even though the other side might not understand a new
feature set usage that we have added. For example, if we add feature set
usage in 7.7 for EQL, in a mixed cluster context if a request is sent to
an old coordinating node, but the master is a new version, then it would
attempt to serialize the usage information for the new feature back to
the old coordinating node, who will blow up on the unrecognized named
writeable. This commit addresses this by making feature usage version
aware, and only serializing those that the other side would understand.
`auto_date_histogram`'s reduction behavior is fairly complex and we have
some fairly complex testing logic for it but it is super difficult to
look at that testing logic and say "ah, that is what it does in this
case". This adds some tests explicit (non-randomized) tests of the
reduction logic that *should* be easier to read.
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
Currently forbidden apis accounts for 800+ tasks in the build. These
tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance
(https://github.com/policeman-tools/forbidden-apis/pull/162), but we
need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis
usages, in preparation for upgrading to 3.0 when it is released.

Added testing of following on top of a closed index.
This could for instance be the old leader index in
cases where leader and follower clusters have been
swapped.
The SLES 12 image's repos appear to no longer have any standard repos.
This commit adds the the standard SLES 12 SP3 repo, and forces expect to
be resolved as it has an issue with the version of tcl/tck (those
packages are thus downgraded to get expect installed).

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.
This directory interferes with notarization and removing it before we
notarize allows us to have a properly notarized
distribution. Conceptually, this directory is only needed when building
a distribution to be installed by Installer (a so-called "pkg"). Since
we are not building such distributions, and this directory interferes
with notarization, we choose to exclude it here. We do this here, rather
than in our notarization process, to ensure that what we run through CI
for testing is also what we ship to the world.
Snapshot deletes should first check the cluster state for an in-progress snapshot
and try to abort it before checking the repository contents. This allows for atomically
checking and aborting a snapshot in the same cluster state update, removing all possible
races where a snapshot that is in-progress could not be found if it finishes between
checking the repository contents and the cluster state.
Also removes confusing races, where checking the cluster state off of the cluster state thread
finds an in-progress snapshot that is then not found in the cluster state update to abort it.
Finally, the logic to use the repository generation of the in-progress snapshot + 1 was error
prone because it would always fail the delete when the repository had a pending generation different from its safe generation when a snapshot started (leading to the snapshot finalizing at a
higher generation).
These issues (particularly that last point) can easily be reproduced by running `SLMSnapshotBlockingIntegTests` in a loop with current `master` (see #54766).
The snapshot resiliency test for concurrent snapshot creation and deletion was made to more
aggressively start the delete operation so that the above races would become visible.
Previously, the fact that deletes would never coincide with initializing snapshots resulted
in a number of the above races not reproducing.
This PR is the most consistent I could get snapshot deletes without changes to the state machine. The fact that aborted deletes will not put the delete operation in the cluster state before waiting for the snapshot to abort still allows for some possible (though practically very unlikely) races. These will be fixed by a state-machine change in upcoming work in #54705 (which will have a much simpler and clearer diff after this change).
Closes#54766
Backport of #55073.
We added tasks to build an ARM distribution and Docker image, but didn't
provide any way to run packaging tests against them. Add extra loops on
the possible Architecture values, and skip tasks that can't be run on
the current Architecture.
* Remove Redundant Cluster State during Snapshot INIT + Master Failover (#54420)
Similar to #54395 we know that a snapshot in INIT state has not
written anything to the repository yet. If we see one from a master
failover, there is no point in moving it to ABORTED before removing it
from the cluster state in a subsequent CS update.
Instead, we can simply remove its job from the CS the first time
we see it on master failover and be done with it.
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).
The MachineLearningIT.testStopDatafeed test was creating 3
jobs each with the default model memory limit of 1GB. This
meant that the test would not run on a machine with less than
10GB of RAM (due to the default ML memory percentage of 30%).
This change reduces the model memory limit for these jobs to
0.5GB, which means the test will run on a machine with only
5GB of RAM.

* Move Snapshot Status Related Method to Appropriate Places
Lots of things living in `SnapshotsService` for no reason other than
that `SnapshotsService` provides the `RepositoriesService`.
Cleaning this up to directly use `RepositoriesService` in the relevant
transport actions and by that shortening the already very complex `SnapshotsService`.
