* 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)
Backport of #39320
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.

* Optimize Bulk Message Parsing and Message Length Parsing
* findNextMarker took almost 1ms per invocation during the PMC rally track
* Fixed to be about an order of magnitude faster by using Netty's bulk `ByteBuf` search
* It is unnecessary to instantiate an object (the input stream wrapper) and throw it away, just to read the `int` length from the message bytes
* Fixed by adding bulk `int` read to BytesReference
This commit renames the retention lease setting
index.soft_deletes.retention.lease so that it is under the namespace
index.soft_deletes.retention_lease. As such, we rename the setting to
index.soft_deletes.retention_lease.period.
This commit adds a new build type (together with deb/rpm/tar/zip) to
represent the official Docker images. This build type will be displayed
in APIs such as the main and nodes info APIs.
Previously, Watcher only attached its listener to indices that started
with the prefix `.watches`, which causes Watcher to silently fail to
schedule newly created Watches if the `.watches` alias is redirected to
an index that does not start with `.watches`.
Watcher now attaches the listener to all indices, so that Watcher can
respond to changes in which index has the `.watches` alias.
Also adjusts the tests to randomly use non-prefixed concrete indices
for .watches and .triggered_watches.
This is related to #35975. It adds documentation on the remote recovery
process. Additionally, it adds documentation about the various settings
that can impact the process.
In case multiple completion suggestion entries have the same score and
surface form, the order in which such options will be returned is
currently not deterministic.
With this commmit we introduce tie-breaking for such situations, based
on shard id, index name, index uuid and doc id like we already do for
ordinary search hits. With this change we also make shardIndex
mandatory when sorting and comparing completion suggestion options,
which was previously only needed later when fetching hits).
Also, we need to make sure shardIndex is properly set when merging
completion suggestions coming from multiple clusters in
`SearchResponseMerger`
This change adds two new cluster privileges:
* manage_data_frame_transforms
* monitor_data_frame_transforms
And two new built-in roles:
* data_frame_transforms_admin
* data_frame_transforms_user
These permit access to the data frame transform endpoints.
(Index privileges are also required on the source and
destination indices for each data frame transform, but
since these indices are configurable they it is not
appropriate to grant them via built-in roles.)
* Soften redundant cast to allow use of `DeterministicTaskQueue` in this class for #39504
* Remove two redundant variables and lower visibility in two possible spots
* Make field `final`
Currently Fuzziness#asDistance(String) doesn't work for custom AUTO values. If
the fuzziness is AUTO, the method returns the correct edit distance to use,
depending on the input string, but for custom AUTO values it currently always
returns an edit distance of 1. Correcting this and adding unit and integration
tests to catch these cases.
Closes#39614
Today we have no chance to fetch actual segment stats for segments that
are currently unloaded. This is relevant in the case of frozen indices.
This allows to monitor how much memory a frozen index would use if it was
unfrozen.
This is a backport of #39631

This change adds support for the concurrent refresh of access
tokens as described in #36872
In short it allows subsequent client requests to refresh the same token that
come within a predefined window of 60 seconds to be handled as duplicates
of the original one and thus receive the same response with the same newly
issued access token and refresh token.
In order to support that, two new fields are added in the token document. One
contains the instant (in epoqueMillis) when a given refresh token is refreshed
and one that contains a pointer to the token document that stores the new
refresh token and access token that was created by the original refresh.
A side effect of this change, that was however also a intended enhancement
for the token service, is that we needed to stop encrypting the string
representation of the UserToken while serializing. ( It was necessary as we
correctly used a new IV for every time we encrypted a token in serialization, so
subsequent serializations of the same exact UserToken would produce
different access token strings)
This change also handles the serialization/deserialization BWC logic:
In mixed clusters we keep creating tokens in the old format and
consume only old format tokens
In upgraded clusters, we start creating tokens in the new format but
still remain able to consume old format tokens (that could have been
created during the rolling upgrade and are still valid)
When reading/writing TokensInvalidationResult objects, we take into
consideration that pre 7.1.0 these contained an integer field that carried
the attempt count
Resolves#36872
The match interval builder analyses input text and converts it to an IntervalSource, and as such
may generate token streams with stopwords. This commit deals with these by using the extend
factory to cover the gaps produced by these stopwords so that phrase and ordered queries work
correctly.
Previously, the security index could be wrongfully recreated. This might
happen if the index was interpreted as missing, as in the case of a fresh
install, but the index existed and the state did not yet recover.
This fix will return HTTP SERVICE_UNAVAILABLE (503) for requests that
try to write to the security index before the state has not been recovered yet.
Investigating how to make DeleteExpiredDataIT faster, it was
revealed that the security audit trail threads were quite hot.
Disabling that seems to be helping quite a bit with making this
test faster. This commit also unmutes the test to see how it goes
with the audit trail disabled.

With this commit we provide more info in an existing error message that is
raised when the file `jvm.dll` cannot be found on Windows when installing
