* Remove empty statements
There are a couple of instances of undocumented empty statements all across the
code base. While they are mostly harmless, they make the code hard to read and
are potentially error-prone. Removing most of these instances and marking blocks
that look empty by intention as such.
* Change test, slightly more verbose but less confusing
Node started with node.data=false and node.master=false can no longer
start if they have index metadata. This avoids resurrecting old indexes
into the cluster and ensures metadata is cleaned out before
re-purposing a node that was previously master or data node.
Issue #27073
When upgrading from 5.4 to 5.5 to 6.7 (inclusive) it was
necessary to ensure there was a mapping for type "doc" on
the ML state index before opening a job. This was because
5.4 created a multi-type ML state index.
In version 7.x we can be sure that any such 5.4 index is no
longer in use. It would have had to be reindexed into the
6.x index format prior to the upgrade to version 7.x.
This changes adds the support to handle `nested` fields in the `composite`
aggregation. A `nested` aggregation can be used as parent of a `composite`
aggregation in order to target `nested` fields in the `sources`.
Closes#28611
The ingest date processor is currently only able to parse joda formats.
However it is not using the existing elasticsearch classes but access
joda directly. This means that our existing BWC layer does not notify
the user about deprecated formats. This commit switches to use the
exising Elasticsearch Joda methods to acquire a date format, that
includes the BWC check and the ability to parse java 8 dates.
The date parsing in ingest has also another extra feature, that the
fallback year, when a date format without a year is used, is the current
year, and not 1970 like usual. This is currently not properly supported
in the DateFormatter class. As this is the only case for this feature
and java time can take care of this using the toZonedDateTime() method,
a workaround just for the joda time parser has been created, that can be
removed soon again from 7.0.
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

- have fully qualified name as node and cluster name
When an index is frozen, two index settings are updated (index.frozen and
index.search.throttled) but the settings version is left unchanged and does
not reflect the settings update. This commit change the
TransportFreezeIndexAction so that it also increases the settings version
when an index is frozen/unfrozen.
This issue has been caught while working on the replication of closed
indices (#3388) in which index metadata for a closed index are updated
to frozen metadata and this specific assertion tripped.
* Stop threads before logging the list of exceptions
* For the broken case of concurrent iteration in the finally block and the threads not having shut down,
use `CopyOnWriteArrayList` to have concurrency safe iteration

TransportAction and BaseRestHandler now no longer extends AbstractComponent. The AbstractComponent no longer has usages so it was deleted.

The default value for ssl.supported_protocols no longer includes TLSv1
as this is an old protocol with known security issues.
Administrators can enable TLSv1.0 support by configuring the
appropriate `ssl.supported_protocols` setting, for example:
xpack.security.http.ssl.supported_protocols: ["TLSv1.2","TLSv1.1","TLSv1"]

Ranaming as follows:
feature -> rank_feature
feature_vector -> rank_features
feature query -> rank_feature query
Ranaming is done to distinguish from other vector types.
Closes#36723
This deprecates the `xpack.watcher.history.cleaner_service.enabled` setting,
since all newly created `.watch-history` indices in 7.0 will use ILM to manage
their retention.
In 8.0 the setting itself and cleanup actions will be removed.
Resolves#32041
From #29453 and #37285, the include_type_name parameter was already present and defaulted to false. This PR makes the following updates:
* Add deprecation warnings to RestCreateIndexAction, plus tests in RestCreateIndexActionTests.
* Add a typeless 'create index' method to the Java HLRC, and deprecate the old typed version. To do this cleanly, I created new CreateIndexRequest and CreateIndexResponse objects that differ from the existing server ones.
In these tests, we initialize the retained_seq_no with NO_OPS_PERFORMED,
thus we should verify that the min of the retained_seq_no is at least
NO_OPS_PERFORMED not 0.
Closes#35994
elasticsearch-node tool helps to restore cluster if half or more of
master eligible nodes are lost. Of course, all bets are off, regarding
data consistency.
There are two parts of the tool: unsafe-bootstrap to be used when there
is still at least one master-eligible node alive and detach-cluster,
when there are no master-eligible nodes left.
This commit implements the first part.
Docs for the tool will be added separately as a part of #37812.
This change split out all the specific GeoHash
classes for the geohash_grid aggregation into
abstract GeoGrid classes that can be re-used for
specific hashing types, like `geohash`
Today, the mapping on the follower is managed and replicated from its
leader index by the ShardFollowTask. Thus, we should prevent users
from modifying the mapping on the follower indices.

This completes the BWC serialisation changes required for a 6.7 master to
inform other nodes of the node-level value of the `minimum_master_nodes`
setting.

When the arguements of PERCENTILE and PERCENTILE_RANK can be folded,
the `ConstantFolding` rule kicks in and calls the `replaceChildren()`
method on `InnerAggregate` which is created from the aggregation rules
of the `Optimizerz. `InnerAggregate` in turn, cannot implement the method
as the logic of creating a new `InnerAggregate` instance from a list of
`Expression`s resides in the Optimizer. So, instead, `ConstantFolding`
should be applied before any of the aggregations related rules.
Fixes: #37099
Reverts #36259 in part to make randomized test fail if no tests are ran.
This is useful when filtering tests as it's easy to make a typo and
think the test ran trough successfully.

This is the last outstanding feature of the old NamingConventionsTask,
so time to remove it.

This change adds a docker compose configuration that's used with
the `elasticsearch.test.fixtures` plugin to start up the image
and check that the TCP ports are up.
We can build on this to add other checks for culster health,
run REST tests, etc.
We can add multiple containers and configurations to the compose
file (e.x. test different env vars) and form clusters.
When we can't map the principal attribute from the configured SAML
attribute in the realm settings, we can't complete the
authentication. We return an error to the user indicating this and
we present them with a list of attributes we did get from the SAML
response to point out that the expected one was not part of that
list. This list will never contain the NameIDs though as they are
not part of the SAMLAttribute list. So we might have a NameID but
just with a different format.
The assertion `assertOpsOnPrimary` does not store seq_no and primary
term of successful deletes to the `lastOpSeqNo` and `lastOpTerm`. This
leads to failures of the subsequence CAS deletes or indexes with seq_no
and term. Moreover, this assertion trips a translog assertion because it
bumps the primary term of some operations but not the primary term of
the engine.

Now that warning headers no longer contain a timestamp of when the
warning was generated, we no longer need to extract the warning value
from the warning to determine whether or not the warning value is
duplicated. Instead, we can compare strings directly.
Further, when de-duplicating warning headers, are constantly rebuilding
sets. Instead of doing that, we can carry about the set with us and
rebuild it if we find a new warning value.
This commit applies both of these optimizations.
Exceptions thrown by the cluster applier service's settings and cluster appliers are bubbled up, and
block the state from being applied instead of silently being ignored. In combination with the cluster
state publishing lag detector, this will throw a node out of the cluster that can't properly apply
cluster state updates.
