Using a Long alone is not strong enough for the id of search contexts
because we reset the id generator whenever a data node is restarted.
This can lead to two issues:
1. Fetch phase can fetch documents from another index
2. A scroll search can return documents from another index
This commit avoids these issues by adding a UUID to SearchContexId.
This is a partial implementation of an endpoint for anomaly
detector model memory estimation.
It is not complete, lacking docs, HLRC and sensible numbers
for many anomaly detector configurations. These will be
added in a followup PR in time for 7.7 feature freeze.
A skeleton endpoint is useful now because it allows work on
the UI side of the change to commence. The skeleton endpoint
handles the same cases that the old UI code used to handle,
and produces very similar estimates for these cases.

We can't always have the same segment stats and doc stats between
InternalEngine and ReadOnlyEngine if there are some fully deleted
segments. ReadOnlyEngine always filters out them. InternalEngine,
however, will keep them if peer recovery retention leases exist or the
number of the retaining operations is non-zero.
This change reverts the fix in #51331 and uses the wrapped reader to
calculate the segment stats and doc stats. For the test, we need to
disable the extra retaining soft-deletes operations.
Closes#51303
This avoids NPE when executing SLM policy when no config was provided.

A previous change (#53029) is causing analysis jobs to wait for certain indices to be made available. While this it is good for jobs to wait, they could fail early on _start.
This change will cause the persistent task to continually retry node assignment when the failure is due to shards not being available.
If the shards are not available by the time `timeout` is reached by the predicate, it is treated as a _start failure and the task is canceled.
For tasks seeking a new assignment after a node failure, that behavior is unchanged.

Lucene 8.5.0 release candidates are imminent. This commit upgrades master to use
the latest snapshot to check that there are no last-minute bugs or regressions.
A freeze operation can partially fail in multiple places, including the
close verification step. This left the index in an unfrozen but
partially closed state. Now throw an exception to retry the freeze step
instead.
This commit changes the Get Aliases API to include hidden indices by
default - this is slightly different from other APIs, but is necessary
to make this API work intuitively.
* Avoid race condition in ILMHistorySotre (#53039)
* Avoid race condition in ILMHistorySotre
This change modifies ILMHistoryStore to always apply correct settings and mappings,
even if template is deleted and not yet recreated. This ensures that ILM history index
is correctly managed by ILM and also fixes flaky history tests that were prone to
triggenring this race.
This commit also refactors and simplifies ILM history tests.

This commit adds a new request object field, "version", containing the version of the requesting client. This parameter is now accepted - and for certain clients required - by the server and the request is validated against it. Currently server's and client's versions still need to be equal in order for the request to be accepted. Relaxing this check is going to be part of future work.
On the clients' side, the only check remaining is to ensure that the peer server is supporting version backwards compatibility (i.e. is on, or newer than a certain release).
(cherry picked from commit a8f413a20fb023bec83af0de1211a2936a7f558c)
Update CommonEqlRestTestCase code to simplify making changes as requested.
Update EqlActionIT to simplify the test code as requested.
Replace Jackson parser with XContent in EqlActionIT.
Whitelist more EQL tests specs that are now supported.
This commit moves the global checkpoint listeners used in CCR to the CCR
thread pool. This removes the last use of the listener thread pool in
the codebase.
This check was added as part of: 0f2d26bdca
Checking this before the test starts makes more sense, because
the watches index has then also be removed.

Today when notifying a global checkpoint listener, we use the listener
thread pool. This commit turns this inside out so that the global
checkpoint listener must provide an executor on which to notify the
listener.
This commit introduces hidden aliases. These are similar to hidden
indices, in that they are not visible by default, unless explicitly
specified by name or by indicating that hidden indices/aliases are
desired.
The new alias property, `is_hidden` is implemented similarly to
`is_write_index`, except that it must be consistent across all indices
with a given alias - that is, all indices with a given alias must
specify the alias as either hidden, or all specify it as non-hidden,
either explicitly or by omitting the `is_hidden` property.
This commit updates the template used for watch history indices with
the hidden index setting so that new indices will be created as hidden.

Datafeed bwc tests have been muted for some time in the 7.x. This is because of date_histogram interval deprecation warnings.
This commit fixes the tests as must as possible while still handling deprecation warnings.
When we test backwards compatibility we often end up in a situation
where we *sometimes* get a warning, and sometimes don't. Like, we won't
get the warning if we're testing against an older version, but we will
in a newer one. Or we won't get the warning if the request randomly
lands on a node with an old version of the code. But we wouldn't if it
randomed into a node with newer code.
This adds `allowed_warnings` to our yaml test runner for those cases:
warnings declared this way are "allowed" but not "required".
Blocks #52959

Tests have been periodically failing due to a race condition on checking a recently `STOPPED` task's state. The `.ml-state` index is not created until the task has already been transitioned to `STARTED`. This allows the `_start` API call to return. But, if a user (or test) immediately attempts to `_stop` that job, the job could stop and the task removed BEFORE the `.ml-state|stats` indices are created/updated.
This change moves towards the task cleaning up itself in its main execution thread. `stop` flips the flag of the task to `isStopping` and now we check `isStopping` at every necessary method. Allowing the task to gracefully stop.
closes#53007
For analytics, we need a consistent way of indicating when a value is missing. Inheriting from anomaly detection, analysis sent `""` when a field is missing. This works fine with numbers, but the underlying analytics process actually treats `""` as a category in categorical values.
Consequently, you end up with this situation in the resulting model
```
{
"frequency_encoding" : {
"field" : "RainToday",
"feature_name" : "RainToday_frequency",
"frequency_map" : {
"" : 0.009844409027270245,
"No" : 0.6472019970785184,
"Yes" : 0.6472019970785184
}
}
}
```
For inference this is a problem, because inference will treat missing values as `null`. And thus not include them on the infer call against the model.
This PR takes advantage of our new `missing_field_value` option and supplies `\0` as the value.
The assumption added in #52631 skips a problematic test
if it fails to create the required conditions for the
scenario it is supposed to be testing. (This happens
very rarely.)
However, before skipping the test it needs to remove the
failed job it has created because the standard test
cleanup code treats failed jobs as fatal errors.
Closes#52608
Upgrading the GCS SDK to the most recent version.
Adjusting (i.e. improving) the REST mock accordingly.
This should significantly boost performance by pulling in
https://github.com/googleapis/java-core/issues/86 in some cases.
This moves the usage statistics gathering from the `AnalyticsPlugin`
into an `AnalyicsUsage`, removing the static state. It also checks the
license level when parsing all analytics aggregations. This is how we
were checking them before but we did it in an easy to forget way. This
way is slightly simpler, I think.
