The logic for handling empty segment files has been
unnecessary ever since #24021 which removes the support
for these files in 6.x -> we can safely remove the
support for restoring these from 7.x+ to simplify the code.
There is no reason to still resolve the
fallback `IndexId` here. It only applies to
`2.x` repos and those we can't read anymore
anyway because they use an `/index` instead of
an `/index-N` blob at the repo root for which
at least 7.x+ does not contain the logic to find
it.
If a job stops right after reindexing is finished but before
we refresh the destination index, we don't refresh at all.
If the job is started again right after, it jumps into the analyzing state.
However, the data is still not searchable.
This is why we were seeing test failures that we start the process
expecting X rows (where X is lower than the expected number of docs)
and we end up getting X+.
We fix this by moving the refresh of the dest index right before
we start the process so it always ensures the data is searchable.

Backport of #48090
The after snapshot action is interfering with SLM deleting snapshots
here it seems, causing concurrent delete exceptions.
Since these tests are now test-scoped there is no reason to run
snapshot deletes after each test so we can remove them to avoid this issue.
Closes#47937
We were not closing repositories on Node shutdown.
In production, this has little effect but in tests
shutting down a node using `MockRepository` and is
currently stuck in a simulated blocked-IO situation
will only unblock when the node's threadpool is
interrupted. This might in some edge cases (many
snapshot threads and some CI slowness) result
in the execution taking longer than 5s to release
all the shard stores and thus we fail the assertion
about unreleased shard stores in the internal test cluster.
Regardless of tests, I think we should close repositories
and release resources associated with them when closing
a node and not just when removing a repository from the CS
with running nodes as this behavior is really unexpected.

* Add SLM support to xpack usage and info APIs
This is a backport of #48096
This adds the missing xpack usage and info information into the
`/_xpack` and `/_xpack/usage` APIs. The output now looks like:
```
GET /_xpack/usage
{
...
"slm" : {
"available" : true,
"enabled" : true,
"policy_count" : 1,
"policy_stats" : {
"retention_runs" : 0,
...
}
}
```
and
```
GET /_xpack
{
...
"features" : {
...
"slm" : {
"available" : true,
"enabled" : true
},
...
}
}
```
Relates to #43663
* Fix missing license
This adds parsing an inference model as a possible
result of the analytics process. When we do parse such a model
we persist a `TrainedModelConfig` into the inference index
that contains additional metadata derived from the running job.
Previously when a numeric literal was enclosed in parentheses and then
negated, the negation was lost and the number was considered positive, e.g.:
`-(5)` was considered as `5` instead of `-5`
`- ( (1.28) )` was considered as `1.28` instead of `-1.28`

Audit messages are stored with millisecond timestamps. If two
messages have the same millisecond timestamp then asserting on
their order is impossible given the information available.
This PR changes the assertion on audit messages in the native
data frame analytics tests to assert that the expected audit
messages exist in any order.
Fixes#48035
which is backport merge and adds a new ingest processor, named enrich processor,
that allows document being ingested to be enriched with data from other indices.
Besides a new enrich processor, this PR adds several APIs to manage an enrich policy.
An enrich policy is in charge of making the data from other indices available to the enrich processor in an efficient manner.

max_empty_searches = -1 in a datafeed update implies
max_empty_searches will be unset on the datafeed when
the update is applied. The isNoop() method needs to
take this -1 to null equivalence into account.
Previously, the safety check for the 2nd argument of the DateAddProcessor was
restricting it to Integer which was wrong since we allow all non-rational
numbers, so it's changed to a Number check as it's done in other cases.
Enhanced some tests regarding the check for an integer (non-rational
argument).

This change adds:
- A new option, allow_lazy_open, to anomaly detection jobs
- A new option, allow_lazy_start, to data frame analytics jobs
Both work in the same way: they allow a job to be
opened/started even if no ML node exists that can
accommodate the job immediately. In this situation
the job waits in the opening/starting state until ML
node capacity is available. (The starting state for data
frame analytics jobs is new in this change.)
Additionally, the ML nightly maintenance tasks now
creates audit warnings for ML jobs that are unassigned.
This means that jobs that cannot be assigned to an ML
node for a very long time will show a yellow warning
triangle in the UI.
A final change is that it is now possible to close a job
that is not assigned to a node without using force.
This is because previously jobs that were open but
not assigned to a node were an aberration, whereas
after this change they'll be relatively common.
This PR adds the ability to run the enrich policy execution task in the background,
returning a task id instead of waiting for the completed operation.
Prior to this change the `target_field` would always be a json array
field in the document being ingested. This to take into account that
multiple enrich documents could be inserted into the `target_field`.
However the default `max_matches` is `1`. Meaning that by default
only a single enrich document would be added to `target_field` json
array field.
This commit changes this; if `max_matches` is set to `1` then the single
document would be added as a json object to the `target_field` and
if it is configured to a higher value then the enrich documents will be
added as a json array (even if a single enrich document happens to be
enriched).
Currently, partial snapshots will eventually build up unless they are
manually deleted. Partial snapshots may be useful if there is not a more
recent successful snapshot, but should eventually be deleted if they are
no longer useful.
With this change, partial snapshots are deleted using the following
strategy: PARTIAL snapshots will be kept until the configured
expire_after period has passed, if present, and then be deleted. If
there is no configured expire_after in the retention policy, then they
will be deleted if there is at least one more recent successful snapshot
from this policy (as they may otherwise be useful for troubleshooting
purposes). Partial snapshots are not counted towards either min_count or
max_count.
Adds a new datafeed config option, max_empty_searches,
that tells a datafeed that has never found any data to stop
itself and close its associated job after a certain number
of real-time searches have returned no data.
Backport of #47922
Make clear in the docs that the role mapping APIs is the preferred
way to manage role mappings and that the role mappings that are
defined in files cannot be viewed or managed with the APIs
Usually syslog timestamps have two spaces before a single
digit day-of-month. However, in some non-syslog cases
where syslog-like timestamps are used there is only one
space. The grok pattern supports this, so the timestamp
parser should too. This change makes the
find_file_structure endpoint do this.
Also fixes another problem that the same test case
exposed in the find_file_structure endpoint, which was
that the exclude_lines_pattern for delimited files was
always created on the assumption the delimiter was a
comma. Now it is based on the actual delimiter.
This commit adds two APIs that allow to pause and resume
CCR auto-follower patterns:
// pause auto-follower
POST /_ccr/auto_follow/my_pattern/pause
// resume auto-follower
POST /_ccr/auto_follow/my_pattern/resume
The ability to pause and resume auto-follow patterns can be
useful in some situations, including the rolling upgrades of
cluster using a bi-directional cross-cluster replication scheme
(see #46665).
This commit adds a new active flag to the AutoFollowPattern
and adapts the AutoCoordinator and AutoFollower classes so
that it stops to fetch remote's cluster state when all auto-follow
patterns associate to the remote cluster are paused.
When an auto-follower is paused, remote indices that match the
pattern are just ignored: they are not added to the pattern's
followed indices uids list that is maintained in the local cluster
state. This way, when the auto-follow pattern is resumed the
indices created in the remote cluster in the meantime will be
picked up again and added as new following indices. Indices
created and then deleted in the remote cluster will be ignored
as they won't be seen at all by the auto-follower pattern at
resume time.
Backport of #47510 for 7.x
Previously, Nullability was set to UNKNOWN instead of TRUE which
resulted on QueryFolder not correctly folding to NULL if any of the args
was null.
Remove the overriding nullable() also for DatePart/DateTrunc to allow
