The secure_settings_password was never taken into consideration in
the ReloadSecureSettings API. This commit fixes that and adds
necessary REST layer testing. Doing so, it also:
- Allows TestClusters to have a password protected keystore
so that it can be set for tests.
- Adds a parameter to the run task so that elastisearch can
be run with a password protected keystore from source.
The usage of local parameter for GetFieldMappingRequest has been removed from the underlying transport action since v2.0.
This PR deprecates the parameter from rest layer. It will be removed in next major version.

These tests do CRUD for component templates, however, for 7.7 some changes weren't backported in the
`_doc` wrapping/unwrapping done for the APIs, this can cause test failures.
This bumps the minimum version for these tests to 7.8, which is okay because component templates are
hidden behind a flag and have no compatibility guarantees for 7.7.

This replaces the last bit of validation that pipeline aggregations
performed on the data nodes with explicit checks in a few
`PipelineAggregationBuilders`. We were *already* catching these
validation errors for pipeline aggregations that require that their
parent be squentially ordered. This just adds validation for pipelines
that require *any* parent like `bucket_selector` and `bucket_sort`.
There were some failures on 7.x of field collapse tests,
where total hits count was less then expected.
This adds an additional test to check total hits count

Today when canceling a task we broadcast ban/unban requests to all nodes

and broadcast the cancellation to only nodes that have outstanding child

requests once it got canceled.

* Use V2 index templates during index creation
This commit changes our index creation code to use (and favor!) V2 index templates during index
creation. The creation precedence goes like so, in order of precedence:
- Existing source `IndexMetadata` - for example, when recovering from a peer or a shrink/split/clone
where index templates should not be applied
- A matching V2 index template, if one is found
- When a V2 template is found, all component templates (in the `composed_of` field) are applied
in the order that they appear, with the index template having the 2nd highest precedence (the
create index request always has the top priority when it comes to index settings)
- All matching V1 templates (the old style)
This also adds index template validation when `PUT`-ing a new v2 index template (because this was
required) and ensures that all index and component templates specify *no* top-level mapping type (it
is automatically added when the template is added to the cluster state).
This does not yet implement fine-grained component template merging of mappings, where we favor
merging only a single field's configuration, that will be done in subsequent work.
This also keeps the existing hidden index behavior present for v1 templates, where a hidden index
will match v2 index templates unless they are global (`*`) templates.

This fixes a serialization bug in `auto_date_histogram` that comes up in
a cluster mixed between pre-7.3.0 and post-7.3.0.
Includes #54429 to keep 7.x looking like master for simpler backports.
Closes#54382
Pipeline aggregations like `stats_bucket`, `sum_bucket`, and
`percentiles_bucket` only operate on buckets that have multiple buckets.
This adds support for those aggregations to `geo_distance`, `ip_range`,
`auto_date_histogram`, and `rare_terms`.
This all happened because we used a marker interface to mark compatible
aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget
to implement the interface.
This replaces the marker interface with an abstract method in
`AggregationBuilder`, `bucketCardinality` which makes you return `NONE`,
`ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At
this point `ONE` and `NONE` amount to about the same thing, but I
suspect that'll be a useful distinction when validating bucket sorts.

This commit changes the pre_filter_shard_size default from 128 to unspecified.
This allows to apply heuristics based on the request and the target indices when deciding
whether the can match phase should run or not. When unspecified, this pr runs the can match phase
automatically if one of these conditions is met:
* The request targets more than 128 shards.
* The request contains read-only indices.
* The primary sort of the query targets an indexed field.
Users can opt-out from this behavior by setting the `pre_filter_shard_size` to a static value.

This commits adds a data stream feature flag, initial definition of a data stream and
the stubs for the data stream create, delete and get APIs. Also simple serialization
tests are added and a rest test to thest the data stream API stubs.
This is a large amount of code and mainly mechanical, but this commit should be
straightforward to review, because there isn't any real logic.
The data stream transport and rest action are behind the data stream feature flag and
are only intialized if the feature flag is enabled. The feature flag is enabled if
elasticsearch is build as snapshot or a release build and the
'es.datastreams_feature_flag_registered' is enabled.
The integ-test-zip sets the feature flag if building a release build, otherwise
rest tests would fail.

This commit, built on top of #51708, allows to modify shard search requests based on informations collected on other shards. It is intended to speed up sorted queries on time-based indices. For queries that are only interested in the top documents.
This change will rewrite the shard queries to match none if the bottom sort value computed in prior shards is better than all values in the shard.
For queries that mix top documents and aggregations this change will reset the size of the top documents to 0 instead of rewriting to match none.
This means that we don't need to keep a search context open for this shard since we know in advance that it doesn't contain any competitive hit.

This commit adjusts the _cat/indices and _cat/aliases APIs to allow

Keyword field values with length more than ignore_above are not
indexed. But highlighters still were retrieving these values
from _source and were trying to highlight them. This sometimes lead to
errors if a field length exceeded max_analyzed_offset. But also this

ignored during indexing.
This PR checks if a keyword value was ignored because of its length,
and if yes, skips highlighting it.

It looks like `date_nanos` fields weren't likely to work properly in
composite aggs because composites iterate field values using points and
we weren't converting the points into milliseconds. Because the doc
values were coming back in milliseconds we ended up geting very confused
and just never collecting sub-aggregations.
This fixes that by adding a method to `DateFieldMapper.Resolution` to
`parsePointAsMillis` which is similarly in name and function to
`NumberFieldMapper.NumberType`'s `parsePoint` except that it normalizes
to milliseconds which is what aggs need at the moment.
Closes#53168
When an composite aggregation is run against an index with a sort that

When we test backwards compatibility we often end up in a situation

lands on a node with an old version of the code. But we wouldn't if it
randomed into a node with newer code.
This adds `allowed_warnings` to our yaml test runner for those cases:
warnings declared this way are "allowed" but not "required".

Computing the stats for completion fields may involve a significant amount of
work since it walks every field of every segment looking for completion fields.
Innocuous-looking APIs like `GET _stats` or `GET _cluster/stats` do this for
every shard in the cluster. This repeated work is unnecessary since these stats
do not change between refreshes; in many indices they remain constant for a
long time.
This commit introduces a cache for these stats which is invalidated on a
refresh, allowing most stats calls to bypass the work needed to compute them on
most shards.

* Smarter copying of the rest specs and tests (#52114)
This PR addresses the unnecessary copying of the rest specs and allows
for better semantics for which specs and tests are copied. By default
the rest specs will get copied if the project applies
`elasticsearch.standalone-rest-test` or `esplugin` and the project
has rest tests or you configure the custom extension `restResources`.
This PR also removes the need for dozens of places where the x-pack
specs were copied by supporting copying of the x-pack rest specs too.
The plugin/task introduced here can also copy the rest tests to the
local project through a similar configuration.
The new plugin/task allows a user to minimize the surface area of
which rest specs are copied. Per project can be configured to include
only a subset of the specs (or tests). Configuring a project to only
copy the specs when actually needed should help with build cache hit
rates since we can better define what is actually in use.
However, project level optimizations for build cache hit rates are
not included with this PR.
Also, with this PR you can no longer use the includePackaged flag on
integTest task.
The following items are included in this PR:
* new plugin: `elasticsearch.rest-resources`
* new tasks: CopyRestApiTask and CopyRestTestsTask - performs the copy
* new extension 'restResources'
```
restResources {
restApi {
includeCore 'foo' , 'bar' //will include the core specs that start with foo and bar
includeXpack 'baz' //will include x-pack specs that start with baz
}
restTests {
includeCore 'foo', 'bar' //will include the core tests that start with foo and bar
includeXpack 'baz' //will include the x-pack tests that start with baz

When `date_histogram` attempts to optimize itself it for a particular
time zone it checks to see if the entire shard is within the same
"transition". Most time zone transition once every size months or
thereabouts so the optimization can usually kicks in.
*But* it crashes when you attempt feed it a time zone who's last DST
transition was before epoch. The reason for this is a little twisted:
before this patch it'd find the next and previous transitions in
milliseconds since epoch. Then it'd cast them to `Long`s and pass them
into the `DateFieldType` to check if the shard's contents were within
the range. The trouble is they are then converted to `String`s which are
*then* parsed back to `Instant`s which are then convertd to `long`s. And
the parser doesn't like most negative numbers. And everything before
epoch is negative.
This change removes the
`long` -> `Long` -> `String` -> `Instant` -> `long` chain in favor of
passing the `long` -> `Instant` -> `long` which avoids the fairly complex
parsing code and handles a bunch of interesting edge cases around
epoch. And other edge cases around `date_nanos`.

This change ensures that the rewrite of the shard request is executed in the network thread or in the refresh listener when waiting for an active shard. This allows queries that rewrite to match_no_docs to bypass the search thread pool entirely even if the can_match phase was skipped (pre_filter_shard_size > number of shards). Coordinating nodes don't have the ability to create empty responses so this change also ensures that at least one shard creates a full empty response while the other can return null ones. This is needed since creating true empty responses on shards require to create concrete aggregators which would be too costly to build on a network thread. We should move this functionality to aggregation builders in a follow up but that would be a much bigger change.
This change is also important for #49601 since we want to add the ability to use the result of other shards to rewrite the request of subsequent ones. For instance if the first M shards have their top N computed, the top worst document in the global queue can be pass to subsequent shards that can then rewrite to match_no_docs if they can guarantee that they don't have any document better than the provided one.
When the `rare_terms` aggregation contained another aggregation it'd
break them. Most of the time. This happened because the process that it
uses to remove buckets that turn out not to be rare was incorrectly
merging results from multiple leaves. This'd cause array index out of
bounds issues. We didn't catch it in the test because the issue doesn't
happen on the very first bucket. And the tests generated data in such a
way that the first bucket always contained the rare terms. Randomizing
the order of the generated data fixed the test so it caught the issue.

When a composite aggregation is reduced using the results from an
index that has one of the fields unmapped we were throwing away the
formatter. This is mildly annoying, except in the case of IP addresses
which were coming out as non-utf-8-characters. And tripping assertions.
This carefully preserves the formatter from the working bucket.
Closes#50600
Adds support for the `offset` parameter to the `date_histogram` source
of composite aggs. The `offset` parameter is supported by the normal
`date_histogram` aggregation and is useful for folks that need to
measure things from, say, 6am one day to 6am the next day.
This is implemented by creating a new `Rounding` that knows how to
handle offsets and delegates to other rounding implementations. That
implementation doesn't fully implement the `Rounding` contract, namely
`nextRoundingValue`. That method isn't used by composite aggs so I can't
be sure that any implementation that I add will be correct. I propose to
leave it throwing `UnsupportedOperationException` until I need it.
Closes#48757
Previously, the following situation would throw an error:
* A search contains a `collapse` on a particular field.
* The search spans multiple indices, and in one index the field is mapped as a
concrete field, but in another it is a field alias.
The error occurs when we attempt to merge `CollapseTopFieldDocs` across shards.
When merging, we validate that the name of the collapse field is the same across
shards. But the name has already been resolved to the concrete field name, so it
will be different on shards where the field was mapped as an alias vs. shards
where it was a concrete field.
This PR updates the collapse field name in `CollapseTopFieldDocs` to the
original requested field, so that it will always be consistent across shards.
Note that in #32648, we already made a fix around collapsing on field aliases.
However, we didn't test this specific scenario where the field was mapped as an
alias in only one of the indices being searched.
This PR adds per-field metadata that can be set in the mappings and is later
returned by the field capabilities API. This metadata is completely opaque to
Elasticsearch but may be used by tools that index data in Elasticsearch to
communicate metadata about fields with tools that then search this data. A
typical example that has been requested in the past is the ability to attach
a unit to a numeric field.
In order to not bloat the cluster state, Elasticsearch requires that this
metadata be small:
- keys can't be longer than 20 chars,
- values can only be numbers or strings of no more than 50 chars - no inner
arrays or objects,
- the metadata can't have more than 5 keys in total.
Given that metadata is opaque to Elasticsearch, field capabilities don't try to
do anything smart when merging metadata about multiple indices, the union of
all field metadatas is returned.
Here is how the meta might look like in mappings:
```json
{
"properties": {
"latency": {
"type": "long",
"meta": {
"unit": "ms"
}
}
}
}
```
And then in the field capabilities response:
```json
{
"latency": {
"long": {
"searchable": true,
"aggreggatable": true,
"meta": {
"unit": [ "ms" ]
}
}
}
}
```
When there are no conflicts, values are arrays of size 1, but when there are
conflicts, Elasticsearch includes all unique values in this array, without
giving ways to know which index has which metadata value:
```json
{
"latency": {
"long": {
"searchable": true,
"aggreggatable": true,
"meta": {
"unit": [ "ms", "ns" ]
}
}
}
}

an edit distance defined by fuzziness, similar to FuzzyQuery.

The cat nodes API performs a `ClusterStateAction` then a `NodesInfoAction`.
Today it accepts the `?local` parameter and passes this to the
`ClusterStateAction` but this parameter has no effect on the `NodesInfoAction`.
This is surprising, because `GET _cat/nodes?local` looks like it might be a
completely local call but in fact it still depends on every node in the
cluster.
This commit deprecates the `?local` parameter on this API so that it can be
removed in 8.0.

Multiple version ranges are allowed to be used in section skip in yml
tests. This is useful when a bugfix was backported to latest versions
and all previous releases contain a wire breaking bug.
examples:

backport #50014
Adds `GET /_script_language` to support Kibana dynamic scripting
language selection.
Response contains whether `inline` and/or `stored` scripts are
enabled as determined by the `script.allowed_types` settings.
For each scripting language registered, such as `painless`,
`expression`, `mustache` or custom, available contexts for the language
are included as determined by the `script.allowed_contexts` setting.
Response format:
```
{
"types_allowed": [
"inline",
"stored"
],
"language_contexts": [
{
"language": "expression",
"contexts": [
"aggregation_selector",
"aggs"
...

},
{
"language": "painless",
"contexts": [

Fixes: #49463
**Backport**
This change adds a dynamic cluster setting named `indices.id_field_data.enabled`.
When set to `false` any attempt to load the fielddata for the `_id` field will fail
with an exception. The default value in this change is set to `false` in order to prevent
fielddata usage on this field for future versions but it will be set to `true` when backporting
to 7x. When the setting is set to true (manually or by default in 7x) the loading will also issue
a deprecation warning since we want to disallow fielddata entirely when https://github.com/elastic/elasticsearch/issues/26472
is implemented.
Closes#43599
JavaDateFormatter should keep the pattern with the prefixed 8 as it will be used for serialisation. The stripped pattern should be used for the enclosed formatters.

Adding support for the `search_type` request parameter to the Ranking Evaluation
API since this parameter can impact the ranking and the metric score and should
be choosen in the same way when evaluating the search as later in the real
search.

* Fix rolling upgrade
Changes auto-id index requests to use optype CREATE, making it compliant with our docs.
This will also make these auto-id index requests compatible with the new "create-doc" index
privilege (which is based on the optype), the default optype is changed to create, just as it is
already documented.
Bulk requests currently do not allow adding "create" actions with auto-generated IDs.
This commit allows using the optype CREATE for append-only indexing operations. This is
mainly the user facing aspect of it.
API spec now use an object for the documentation field. _common was not updated yet. This commit updates _common.json and its corresponding parser.

Follow up from #42346. Since the `methods` array is in order of
preference when calling the index API with an `{id}` we prefer to use
the `PUT` http method.
When waiting for no initializing shards we also have to wait for events
when we have more than one node in the cluster. When the primary is
started, there is a short period of time, where neither the primary nor
any of the replicas are initializing.
Closes#46535
We leave replicas unassigned until we reroute after the primary shard
starts. If a cluster health request with wait_for_no_initializing_shards
is executed before the reroute, it will return immediately although
there will be some initializing replicas. Peer recoveries of those
shards can prevent translog on the primary from trimming.
We add wait_for_events to the cluster health request so that it will
execute after the reroute.
Closes#46425
* Support geotile_grid aggregation in composite agg sources (#45810)
Adds support for `geotile_grid` as a source in composite aggs.
Part of this change includes adding a new docFormat of `GEOTILE` that formats a hashed `long` value into a geotile formatting string `zoom/x/y`.
Since #45136, we use soft-deletes instead of translog in peer recovery.
There's no need to retain extra translog to increase a chance of
operation-based recoveries. This commit ignores the translog retention
policy if soft-deletes is enabled so we can discard translog more
quickly.

* Add is_write_index column to cat.aliases (#44772)
Aliases have had the option to set `is_write_index` since 6.4,
but the cat.aliases action was never updated.
* correct version bounds to 7.4
* Repository Cleanup Endpoint (#43900)
* Snapshot cleanup functionality via transport/REST endpoint.
* Added all the infrastructure for this with the HLRC and node client
* Made use of it in tests and resolved relevant TODO
* Added new `Custom` CS element that tracks the cleanup logic.
Kept it similar to the delete and in progress classes and gave it
some (for now) redundant way of handling multiple cleanups but only allow one
* Use the exact same mechanism used by deletes to have the combination
of CS entry and increment in repository state ID provide some
concurrency safety (the initial approach of just an entry in the CS
was not enough, we must increment the repository state ID to be safe
against concurrent modifications, otherwise we run the risk of "cleaning up"
blobs that just got created without noticing)
* Isolated the logic to the transport action class as much as I could.
It's not ideal, but we don't need to keep any state and do the same
for other repository operations
(like getting the detailed snapshot shard status)
* Update the REST API specification
This patch updates the REST API spefication in JSON files to better encode deprecated entities,
to improve specification of URL paths, and to open up the schema for future extensions.
Notably, it changes the `paths` from a list of strings to a list of objects, where each
particular object encodes all the information for this particular path: the `parts` and the `methods`.
Among the benefits of this approach is eg. encoding the difference between using the `PUT` and `POST`
methods in the Index API, to either use a specific document ID, or let Elasticsearch generate one.
Also `documentation` becomes an object that supports an `url` and also a `description` which is a
new field.
* Adapt YAML runner to new REST API specification format
The logic for choosing the path to use when running tests has been
simplified, as a consequence of the path parts being listed under each
path in the spec. The special case for create and index has been removed.
Also the parsing code has been hardened so that errors are thrown earlier
when the structure of the spec differs from what expected, and their
error messages should be more helpful.
This commit adds a deprecation warning in 7.x for the Force Merge API
when both only_expunge_deletes and max_num_segments are set in a request.

With this change, we will return primary_term and seq_no of the current
document if an update is detected as a noop. We already return the
version; hence we should also return seq_no and primary_term.
Relates #42497
Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the
difference that the number of primary shards is kept the same. In case where the filesystem
provides hard-linking capabilities, this is a very cheap operation.
Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it
supports the same options as the split and shrink APIs.
Closes#44128
This is a refactor to current JSON logging to make it more open for extensions
and support for custom ES log messages used inDeprecationLogger IndexingSlowLog , SearchSLowLog
We want to include x-opaque-id in deprecation logs. The easiest way to have this as an additional JSON field instead of part of the message is to create a custom DeprecatedMessage (extends ESLogMEssage)
These messages are regular log4j messages with a text, but also carry a map of fields which can then populate the log pattern. The logic for this lives in ESJsonLayout and ESMessageFieldConverter.
Similar approach can be used to refactor IndexingSlowLog and SearchSlowLog JSON logs to contain fields previously only present as escaped JSON string in a message field.
closes#41350
backport #41354
This adds a `rare_terms` aggregation. It is an aggregation designed
to identify the long-tail of keywords, e.g. terms that are "rare" or
have low doc counts.
This aggregation is designed to be more memory efficient than the
alternative, which is setting a terms aggregation to size: LONG_MAX
(or worse, ordering a terms agg by count ascending, which has
unbounded error).
This aggregation works by maintaining a map of terms that have
been seen. A counter associated with each value is incremented
when we see the term again. If the counter surpasses a predefined
threshold, the term is removed from the map and inserted into a cuckoo
filter. If a future term is found in the cuckoo filter we assume it
was previously removed from the map and is "common".
The map keys are the "rare" terms after collection is done.
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 a prefix intervals source, allowing you to search

Both TransportAnalyzeAction and CategorizationAnalyzer have logic to build
custom analyzers for index-independent analysis. A lot of this code is duplicated,
and it requires the AnalysisRegistry to expose a number of internal provider
classes, as well as making some assumptions about when analysis components are
constructed.
This commit moves the build logic directly into AnalysisRegistry, reducing the
registry's API surface considerably.
Previously, a reindex request had two different size specifications in the body:
* Outer level, determining the maximum documents to process
* Inside the source element, determining the scroll/batch size.
The outer level size has now been renamed to max_docs to
avoid confusion and clarify its semantics, with backwards compatibility and
deprecation warnings for using size.
Similarly, the size parameter has been renamed to max_docs for
update/delete-by-query to keep the 3 interfaces consistent.
Finally, all 3 endpoints now support max_docs in both body and URL.

Adds a metadata field to snapshots which can be used to store arbitrary
key-value information. This may be useful for attaching a description of
why a snapshot was taken, tagging snapshots to make categorization
easier, or identifying the source of automatically-created snapshots.
Tests were failing in mixed cluster after more broad warnings were introduced
in 6.x These tests were using `yyyy-MM-dd` pattern which is now warning about
the change of `y` to `u`. However, using predefined pattern
`strict_date` which uses the same format prevents the warning from being
generate and allow smooth upgrade/work in mixed cluster.
relates #42679
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
