This commit removes the "doc" type from watcher internal indexes.
The template still carries the "_doc" type since that is needed for
the internal representation.
This impacts the .watches, .triggered-watches, and .watch-history indexes.
External consumers do not need any changes since all external calls
go through the _watcher API, and should not interact with the the .index directly.

This test was more complicated than necessary, where we were capturing
requests to prevent removal of retention leases, so that our forget
follower request could remove the retention leases instead. Instead, a
pause is enough to ensure that the retention leases are not re-added
after we remove them by the forget follower request. This commit
simplifies this test, and should remove some spurious failures.

This commit changes the type from "doc" to "_doc" for the
.logstash-management template. Since this is an internally
managed template it does not always go through the REST
layer for it's internal representation. The internal
representation requires the default "_doc" type, which for
external templates is added in the REST layer.

Prior to this commit (and after 6.5.0), if an ingest node changes
the _index in a pipeline, the original target index would be created.
For daily indexes this could create an extra, empty index per day.
This commit changes the TransportBulkAction to execute the ingest node
pipeline before attempting to create the index. This ensures that the
only index created is the original or one set by the ingest node pipeline.
This was the execution order prior to 6.5.0 (#32786).
The execution order was changed in 6.5 to better support default pipelines.
Specifically the execution order was changed to be able to read the settings
from the index meta data. This commit also includes a change in logic such
that if the target index does not exist when ingest node pipeline runs, it
will now pull the default pipeline (if one exists) from the settings of the
best matched of the index template.

When trace logging is enabled we log the computed steps for a policy. This
commit makes sure that the steps that are logged are in the same order they will
be run when the policy executes. This makes it much easier to reason about the
policy if the move-to-step API is ever required in the future.
A TLS handshake requires exchanging multiple messages to initiate a
session. If one side decides to close during the handshake, it is
supposed to send a close_notify alert (similar to closing during
application data exchange). The java SSLEngine engine throws an
exception when this happens. We currently log this at the warn level if
trace logging is not enabled. This level is too high for a valid
scenario. Additionally it happens all the time in tests (quickly closing
and opened transports). This commit changes this to be logged at the
debug level if trace is not enabled. Additionally, it extracts the
transport security exception handling to a common class.
This commit introduces the forget follower API. This API is needed in cases that
unfollowing a following index fails to remove the shard history retention leases
on the leader index. This can happen explicitly through user action, or
implicitly through an index managed by ILM. When this occurs, history will be
retained longer than necessary. While the retention lease will eventually
expire, it can be expensive to allow history to persist for that long, and also
prevent ILM from performing actions like shrink on the leader index. As such, we
introduce an API to allow for manual removal of the shard history retention
leases in this case.
* Back port build changes from #39102
This back-ports how versions are determined and bwc test are set up from
#39102 without enabling the bwc from current version tests so it's
easier/possible to backmerge future buld changes.
It's expected that the tets are lacking many of the required fixes in
this version to enable them.
Previously all the threads were writing the received tokens to a
HashSet. In cases with many threads, sometimes (1 every ~25 tests)
calling size() on the HashSet returned 2 even though it seemed to
contain only one String and there was no evidence from logging that
threadSecurityClient.refreshToken() ever returned a different
access or refresh token.
This commit changes the test to use a ConcurrentHashMap instead,
checking that we only received one pair of access token/refresh token
eventually. It also adds a check so that we won't take into consideration
tokens that are returned after 30s, hence not in the concurrent refresh
time window.
Due to migration from joda to java.time licence expiration 'full date' format
has to use 4-char pattern (MMMM). Also since jdk9 the date with ROOT
locale will still return abbreviated days and month names.

* Wipe Snapshots Before Indices in RestTests
* If we have a snapshot ongoing from the previous test and enter this method, then deleting the indices fails, which in turn fails the whole wipe
* Fixed by first deleting/aborting snapshots
We need to unwrap and use the actual cause when determining if the node
with primary shard is shutting down because TransportService will throw
a TransportException wrapped in a SendRequestTransportException.
Relates #39584
Today when a replicated write operation fails to execute on a replica,
the primary will reach out to the master to fail that replica (and mark
it stale). We then won't ack that request until the master removes the
failing replica; otherwise, we will lose the acked operation if the
failed replica is still in the in-sync set. However, if a node with the
primary is shutting down, we might ack such request even though we are
unable to send a shard-failure request to the master. This happens
because we ignore NodeClosedException which is triggered when the
ClusterService is being closed.
Closes#39467
This adds the capability to snapshot replicated closed indices.
It also changes snapshot requests in v8.0.0 to automatically expand wildcards to closed indices and hence start snapshotting closed indices by default. For v7.1.0 and above, wildcards are by default only expanded to open indices, which can be changed by explicitly setting the expand_wildcards option either to all or closed.
Note that indices are always restored as open indices, even if they have been snapshotted as closed replicated indices.

Lucene added an optimization to leave the term dictionary on disk
for non-id like fields. This change happened very late in the release
processes such that it's better to have an escape hatch if certain
use-cases are hurt by this optimization. This setting might be
removed in the future if it turns out to be unnecessary.
Fixes several errors of the token retry logic:
* not checking for backoff.hasNext() before calling backoff.next()
* checking for backoff.hasNext() without calling backoff.next()
* not preserving the context on the retry
* calling scheduleWithFixedDelay instead of schedule
Currently SearchServiceTests.testCloseSearchContextOnRewriteException can fail
if a refresh happens while we test for the SearchPhaseExecutionException that is
thrown later in the test. The test takes the current Store#refCount and expects
it to be the same after the exception is thrown. If a refresh happens in that
interval however, the refCound will be different, causing the test to fail. This
can be provoked e.g. by running this section in a tight loop.
Switching of refresh for this tests solves the issue.
This change does the following:
1. Makes the per-node setting xpack.ml.max_open_jobs
into a cluster-wide dynamic setting
2. Changes the job node selection to continue to use the
per-node attributes storing the maximum number of open
jobs if any node in the cluster is older than 7.1, and
use the dynamic cluster-wide setting if all nodes are on
7.1 or later
3. Changes the docs to reflect this
4. Changes the thread pools for native process communication
from fixed size to scaling, to support the dynamic nature
of xpack.ml.max_open_jobs
5. Renames the autodetect thread pool to the job comms
thread pool to make clear that it will be used for other
types of ML jobs (data frame analytics in particular)

When preparing the state to send to other nodes, we're serializing it
for each node, despite using putIfAbsent.
This commit checks if the state was already serialized for this node
version before performing the potentially expensive computation.
The map is not used by multiple threads, so computeIfAbsent is not
needed (and could not be used here easily, because IOException could
be thrown).
(cherry picked from commit c99be63b43f5250f3cd220130df73c5e9e097459)
When a node is joining the cluster we ensure that it can send requests to the
master _at that time_. If it joins the cluster and _then_ loses the ability to
send requests to the master then it should be removed from the cluster. Today
this is not the case: the master can still receive responses to its follower
checks, and receives acknowledgements to cluster state publications, so has no
reason to remove the node.
This commit changes the handling of follower checks so that they fail if they
come from a master that the other node was following but which it now believes
to have failed.
Today the `GroupedActionListener` accepts a `defaults` parameter but all
callers pass an empty list. Also it is permitted to pass an empty group but
this is trappy because the delegated listener is never be called in that case.
This commit removes the `defaults` parameter and forbids an empty group.
As we are moving to single type indices,
we need to address this change in security-related indexes.
To address this, we are
- updating index templates to use preferred type name `_doc`
- updating the API calls to use preferred type name `_doc`
Upgrade impact:-
In case of an upgrade from 6.x, the security index has type
`doc` and this will keep working as there is a single type and `_doc`
works as an alias to an existing type. The change is handled in the
`SecurityIndexManager` when we load mappings and settings from
the template. Previously, we used to do a `PutIndexTemplateRequest`
with the mapping source JSON with the type name. This has been
modified to remove the type name from the source.
So in the case of an upgrade, the `doc` type is updated
whereas for fresh installs `_doc` is updated. This happens as
backend handles `_doc` as an alias to the existing type name.
An optional step is to `reindex` security index and update the
type to `_doc`.
Since we do not support the security audit log index,
that template has been deleted.
