Action is a class that encapsulates meta information about an action
that allows it to be called remotely, specifically the action name and
response type. With recent refactoring, the action class can now be
constructed as a static constant, instead of needing to create a
subclass. This makes the old pattern of creating a singleton INSTANCE
both misnamed and lacking a common placement.
This commit renames Action to ActionType, thus allowing the old INSTANCE
naming pattern to be TYPE on the transport action itself. ActionType
also conveys that this class is also not the action itself, although
this change does not rename any concrete classes as those will be
removed organically as they are converted to TYPE constants.

Renames `_id_copy` to `ml__id_copy` as field names starting with
underscore are deprecated. The new field name `ml__id_copy` was
chosen as an obscure enough field that users won't have in their data.
Otherwise, this field is only intented to be used by df-analytics.
Today the `DiskThresholdMonitor` limits the frequency with which it submits
reroute tasks, but it might still submit these tasks faster than the master can
process them if, for instance, each reroute takes over 60 seconds. This causes
a problem since the reroute task runs with priority `IMMEDIATE` and is always
scheduled when there is a node over the high watermark, so this can starve any
other pending tasks on the master.
This change avoids further updates from the monitor while its last task(s) are
still in progress, and it measures the time of each update from the completion
time of the reroute task rather than its start time, to allow a larger window
for other tasks to run.
It also now makes use of the `RoutingService` to submit the reroute task, in
order to batch this task with any other pending reroutes. It enhances the
`RoutingService` to notify its listeners on completion.

Introduces a new `ConsistentSecureSettingsValidatorService` service that exposes
a single public method, namely `allSecureSettingsConsistent`. The method returns
`true` if the local node's secure settings (inside the keystore) are equal to the
master's, and `false` otherwise. Technically, the local node has to have exactly
the same secure settings - setting names should not be missing or in surplus -
for all `SecureSetting` instances that are flagged with the newly introduced
`Property.Consistent`. It is worth highlighting that the `allSecureSettingsConsistent`
is not a consensus view across the cluster, but rather the local node's perspective
in relation to the master.
If a job is opened and then closed and does nothing in
between then it should not persist any results or state
documents. This change adapts the no-op job test to
assert no results in addition to no state, and to log
any documents that cause this assertion to fail.

The Action base class currently works for both Streamable and Writeable
response types. This commit intorduces StreamableResponseAction, for
which only the legacy Action implementions which provide newResponse()
will extend. This eliminates the need for overriding newResponse() with
an UnsupportedOperationException.

Since #41817 was merged the ml-cpp zip file for any
given version has been cached indefinitely by Gradle.
This is problematic, particularly in the case of the
master branch where the version 8.0.0-SNAPSHOT will
be in use for more than a year.
This change tells Gradle that the ml-cpp zip file is
a "changing" dependency, and to check whether it has
changed every two hours. Two hours is a compromise
between checking on every build and annoying developers
with slow internet connections and checking rarely
causing bug fixes in the ml-cpp code to take a long
time to propagate through to elasticsearch PRs that
rely on them.
Today when an index is closed all its shards are forced flushed
but the translog files are left around. As explained in #42445
we'd like to trim the translog for closed indices in order to
consume less disk space. This commit reuses the existing
AsyncTrimTranslogTask task and reenables it for closed indices.
At the time the task is executed, we should have the guarantee
that nothing holds the translog files that are going to be removed.
It also leaves a short period of time (10 min) during which translog
files of a recently closed index are still present on disk. This could
also help in some cases where the closed index is reopened
shortly after being closed (in order to update an index setting
for example).

This change removes the ability to wrap an IndexSearcher in plugins. The IndexSearcherWrapper is replaced by an IndexReaderWrapper and allows to wrap the DirectoryReader only. This simplifies the creation of the context IndexSearcher that is used on a per request basis. This change also moves the optimization that was implemented in the security index searcher wrapper to the ContextIndexSearcher that now checks the live docs to determine how the search should be executed. If the underlying live docs is a sparse bit set the searcher will compute the intersection
betweeen the query and the live docs instead of checking the live docs on every document that match the query.

This commit adds a wildcard intervals source, similar to the prefix. It
also changes the term parameter in prefix to read prefix, to bring it
in to line with the pattern parameter in wildcard.
Closes#43198
This commit adds support for multiple source indices.
In order to deal with multiple indices having different mappings,
it attempts a best-effort approach to merge the mappings assuming
there are no conflicts. In case conflicts exists an error will be
returned.
To allow users creating custom mappings for special use cases,
the destination index is now allowed to exist before the analytics
job runs. In addition, settings are no longer copied except for
the `index.number_of_shards` and `index.number_of_replicas`.
Currently changing resources (like dictionaries, synonym files etc...) of search
time analyzers is only possible by closing an index, changing the underlying
resource (e.g. synonym files) and then re-opening the index for the change to
take effect.
This PR adds a new API endpoint that allows triggering reloading of certain
analysis resources (currently token filters) that will then pick up changes in
underlying file resources. To achieve this we introduce a new type of custom
analyzer (ReloadableCustomAnalyzer) that uses a ReuseStrategy that allows
swapping out analysis components. Custom analyzers that contain filters that are
markes as "updateable" will automatically choose this implementation. This PR
also adds this capability to `synonym` token filters for use in search time
analyzers.
Relates to #29051
When we added support for TokenFilterFactories to specialise how they were used when parsing
synonym files, PreConfiguredTokenFilters were set up to either apply themselves, or be ignored.
This behaviour is a leftover from an earlier iteration, and also has an incorrect default.
This commit makes preconfigured token filters usable in synonym file parsing by default, and brings
those filters that should not be used into line with index-specific filter factories; in indexes created
before version 7 we emit a deprecation warning, and we throw an error in indexes created after.
Fixes#38793
TransportNodesAction provides a mechanism to easily broadcast a request
to many nodes, and collect the respones into a high level response. Each
node has its own request type, with a base class of BaseNodeRequest.
This base request requires passing the nodeId to which the request will
be sent. However, that nodeId is not used anywhere. It is private to the
base class, yet serialized to each node, where the node could just as
easily find the nodeId of the node it is on locally.
This commit removes passing the nodeId through to the node request
creation, and guards its serialization so that we can remove the base
request class altogether in the future.
GatewayIndexStateIT#testRecoverBrokenIndexMetadata replies on the
flushing on shutdown. This behaviour, however, can be randomly disabled
in MockInternalEngine.

Adds support for the situation where only voting-only nodes are bootstrapped. In that case, they will
still try to become elected and bring full master nodes into the cluster.
Search requests executed through the SecurityIndexSearcherWrapper throw
an UnsupportedOperationException if they match a sparse role query.
When low level cancellation is activated (which is the default since #42857),
the context index searcher creates a weight that doesn't handle #scorer.
This change fixes this bug and adds a test to ensure that we check this case.
Currently `AbstractQueryTestCase#testToQuery` checks the search context cachable
flag. This is a bit fragile due to the high randomization of query builders
performed by this general test. Also we might only rarely check the
"interesting" cases because they rarely get generated when fully randomizing the
query builder.
This change moved the general checks out ot #testToQuery and instead adds
dedicated cache tests for those query builders that exhibit something other than
the default behaviour.
Closes#43200
#26625 deprecated delimited_payload_filter and added tests to check
that warnings would be emitted when both a normal and pre-configured
filter were used. Unfortunately, due to a bug in the Analyze API, the pre-
configured filter check was never actually triggered, and it turns out that
the deprecation warning was not in fact being emitted in this case.
#43568 fixed the Analyze API bug, which then surfaced this on backport.
This commit ensures that the preconfigured filter also emits the warnings
and triggers an error if a new index tries to use a preconfigured
delimited_payload_filter
When a named token filter or char filter is passed as part of an Analyze API
request with no index, we currently try and build the relevant filter using no
index settings. However, this can miss cases where there is a pre-configured
filter defined in the analysis registry. One example here is the elision filter, which
has a pre-configured version built with the french elision set; when used as part
of normal analysis, this preconfigured set is used, but when used as part of the
Analyze API we end up with NPEs because it tries to instantiate the filter with
no index settings.
This commit changes the Analyze API to check for pre-configured filters in the case
that the request has no index defined, and is using a name rather than a custom
definition for a filter.
It also changes the pre-configured `word_delimiter_graph` filter and `edge_ngram`
tokenizer to make their settings consistent with the defaults used when creating
them with no settings

It is possible for internal ML indices like `.data-frame-notifications-1` to leak,
