This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
This commit adds Delete Repository, the associated docs and tests for
the high level REST API client. It also cleans up a seemingly innocuous
line in the RestDeleteRepositoryAction and some naming in SnapshotIT.

The copy_settings parameter will be removed in Elasticsearch 8.0.0. This
commit adds an assertion message that to clean up this code when master
is bumped to 8.0.0.
Added dedicated script contexts for:
* script function score
* script sorting
* terms_set query
Scripts for these contexts will either have a specific return value or
use scoring and therefor in the future will need their own scripting classes.

The getDate() and getDates() existed prior to 5.x on long fields in
scripting. In 5.x, a new Date type for ScriptDocValues was added. The
getDate() and getDates() methods were left on long fields and added to date
fields to ease the transition. This commit removes those methods for
7.0.
Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
I still do not like == false. However, I am so use to reading it that
today I read this line of code and could not understand how it could
possibly be doing the right thing. It was only when I finally noticed
the ! that the code made sense. This commit changes this code to be in
our style of == false. I still do not like == false.
Get Settings API changes have now been backported to version 6.4, and
therefore the latest version must send and expect the extra fields when
communicating with 6.4+ code.

Currently in a rescore request if window_size is smaller than
the top N documents returned (N=size), explanation of scores could be incorrect
for documents that were a part of topN and not part of rescoring.
This PR corrects this, but saving in RescoreContext docIDs of documents
for which rescoring was applied, and adding rescoring explanation
only for these docIDs.
Closes#28725
The camel case name `nGram` should be removed in favour of `ngram` and
similar for `edgeNGram` and `edge_ngram`. Before removal, we need to
deprecate the camel case names first. This change adds deprecation
warnings for indices with versions 6.4.0 and higher and logs deprecation
warnings.
Since #30143, the Cluster State API should always returns the current
cluster_uuid in the response body, regardless of the metrics filters.
This is not exactly true as it is returned only if metadata metrics and
no specific indices are requested.
This commit fixes the behavior to always return the cluster_uuid and
add new test.
This test failed but the cause is not obvious. This commit adds more
debug logging traces so that if it reproduces we could gather more
information.

Date histograms on non-fixed timezones such as `Europe/Paris` proved much slower
than histograms on fixed timezones in #28727. This change mitigates the issue by
using a fixed time zone instead when shard data doesn't cross a transition so
that all timestamps share the same fixed offset. This should be a common case
with daily indices.
NOTE: Rewriting the aggregation doesn't work since the timezone is then also
used on the coordinating node to create empty buckets, which might be out of the
range of data that exists on the shard.
NOTE: In order to be able to get a shard context in the tests, I reused code
from the base query test case by creating a new parent test case for both
queries and aggregations: `AbstractBuilderTestCase`.
Mitigates #28727
This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- MovingFunctions.max()
- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
The TemplateUpgradeService is a system service that allows for plugins
to register templates that need to be upgraded. These template upgrades
should always happen in a system context as they are not a user
initiated action. For security integrations, the lack of running this
in a system context could lead to unexpected failures. The changes in
this commit set an empty system context for the execution of the
template upgrades performed by this service.

When processing a top-level sibling pipeline, we destructively sublist
the path by assigning back onto the same variable. But if aggs are
specified such:
A. Multi-bucket agg in the first entry of our internal list
B. Regular agg as the immediate child of the multi-bucket in A
C. Regular agg with the same name as B at the top level, listed as the
second entry in our internal list
D. Finally, a pipeline agg with the path down to B
We'll get class cast exception. The first agg will sublist the path
from [A,B] to [B], and then when we loop around to check agg C,
the sublisted path [B] matches the name of C and it fails.
The fix is simple: we just need to store the sublist in a new object
so that the old path remains valid for the rest of the aggs in the loop
Closes#30608
* Fixes IndiceOptionsTests to serialise correctly
Previous to this change `IndicesOptionsTests.testSerialisation()` would
select a complete random version for both the `StreamOutput` and the
`StreamInput`. This meant that the output could be selected as 7.0+
while the input was selected as <7.0 causing the stream to be written
in the new format and read in teh old format (or vica versa). This
change splits the two cases into different test methods ensuring that
the Streams are at least on compatibile versions even if they are on
different versions.
* Use same random version for input and output streams

This change adds a `listTasks` method to the high level java
ClusterClient which allows listing running tasks through the
task management API.

This commit adds Create Repository, the associated docs and tests
for the high level REST API client. A few small changes to the
PutRepository Request and Response went into the commit as well.
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
* Refactor IndicesOptions to not be byte-based
This refactors IndicesOptions to be enum/enummap based rather than using a byte
as a bitmap for each of the options. This is necessary because we'd like to add
additional options, but we ran out of bits.
Backwards compatibility is kept for earlier versions so the option serialization
does not change the options.
Relates sort of to #30188
When we split/shrink an index we open several IndexWriter instances
causeing file-deletes to be pending on windows. This subsequently fails
when we open an IW to bootstrap the index history due to pending deletes.
This change sidesteps the check since we know our history goes forward
in terms of files and segments.
Closes#30416
The order in which double values are added in java can give different results
for the sum, so we need to allow a certain delta in the test assertions. The
current value was still a bit too low, resulting in rare test failures. This
change increases the allowed margin of error by a factor of ten.
In #28255 the implementation of the elasticsearch.keystore was changed
to no longer be built on top of a PKCS#12 keystore. A side effect of
that change was that calling getString or getFile on a closed
KeyStoreWrapper ceased to throw an exception, and would instead return
a value consisting of all 0 bytes.
This change restores the previous behaviour as closely as possible.
It is possible to retrieve the _keys_ from a closed keystore, but any
attempt to get or set the entries will throw an IllegalStateException.
Now that the change to deprecate copy settings and disallow it being
explicitly set to false is backported, this commit adjusts the BWC
versions in master.
Deprecate the use of empty templates. Bug fix allows empty
templates/scripts to be loaded on start up for upgrades/restarts,
but empty templates can no longer be created.
#30423 combined auto-expansion in the same cluster state update where nodes are removed. As
the auto-expansion step would run before deassociating the dead nodes from the routing table, the
auto-expansion would possibly remove replicas from live nodes instead of dead ones. This commit
reverses the order to ensure that when nodes leave the cluster that the auto-expand-replica
functionality only triggers after failing the shards on the removed nodes. This ensures that active
shards on other live nodes are not failed if the primary resided on a now dead node.
Instead, one of the replicas on the live nodes first gets promoted to primary, and the auto-
expansion (removing replicas) only triggers in a follow-up step (but still same cluster state update).

We currently have a separate endpoint for retrieving settings from all indices. We introduced such endpoint when removing comma-separated feature parsing for GetIndicesAction. The RestGetAllSettingsAction duplicates the code to print out the response that we already have in GetSettingsResponse (since it became a ToXContentObject), and uses the get index API internally instead of the get settings API, but the response is the same, hence we can fold get all settings and get settings in a single API, which is what this commit does.
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The second set of assertions was accidentally using the count's
moving average for the error delta in the value's moving average
assertion. This fixes the typo, and unmutes the test.
Closes#29456
The following tokenizers were moved: classic, edge_ngram,
letter, lowercase, ngram, path_hierarchy, pattern, thai, uax_url_email and
whitespace.
Left keyword tokenizer factory in server module, because
normalizers directly depend on it.This should be addressed on a
follow up change.

We want copying settings to be the default behavior. This commit
deprecates not copying settings, and disallows explicitly not copying
settings. This gives users a transition path to the future default
behavior.
