Théophile Helleboid - chtitux 23e419a7aa SLM PUT: add precision on date math support in indices parameter (#55203)
It was not clear for me that `indices` parameter supports date math expression.

I think it may be worth to add the precision in the documentation.

Add xpack setting deprecations to deprecation API (#56290)
* Add xpack setting deprecations to deprecation API

The deprecated settings showed up in the deprecation log file by
default, but I did not add them to the deprecation API. This commit
fixes that. Now if you use one of the deprecated basic feature
enablement settings, calling _monitoring/deprecations will inform you of
that fact.

* Remove incorrectly backported settings documents

It seems that I backported these docs to the wrong place in #56061,
in #55980, and in #56167. I hope they're in the right place now.

Create plugin for internalClusterTest task (#56067)
This commit creates a new gradle plugin to provide a separate task name

converted to use the new plugin in this PR is server, as an example. The
remaining cases in x-pack will be handled in followups.

Deprecated xpack "enable" settings should be no-ops (#55416) (#56167)
The following settings are now no-ops:

* xpack.flattened.enabled
* xpack.logstash.enabled
* xpack.rollup.enabled
* xpack.slm.enabled
* xpack.sql.enabled
* xpack.transform.enabled
* xpack.vectors.enabled

Since these settings no longer need to be checked, we can remove settings
parameters from a number of constructors and methods, and do so in this
commit.

We also update documentation to remove references to these settings.

[7.x][ML] More advanced model snapshot retention options (#56194)
This PR implements the following changes to make ML model snapshot
retention more flexible in advance of adding a UI for the feature in
an upcoming release.

- The default for `model_snapshot_retention_days` for new jobs is now
  10 instead of 1
- There is a new job setting, `daily_model_snapshot_retention_after_days`,
  that defaults to 1 for new jobs and `model_snapshot_retention_days`
  for pre-7.8 jobs
- For days that are older than `model_snapshot_retention_days`, all
  model snapshots are deleted as before
- For days that are in between `daily_model_snapshot_retention_after_days`
  and `model_snapshot_retention_days` all but the first model snapshot
  for that day are deleted
- The `retain` setting of model snapshots is still respected to allow
  selected model snapshots to be retained indefinitely

SQL: Fix DATETIME_PARSE behaviour regarding timezones (#56158) (#56182)
Previously, when the timezone was missing from the datetime string
and the pattern, UTC was used, instead of the session defined timezone.
Moreover, if a timezone was included in the datetime string and the
pattern then this timezone was used. To have a consistent behaviour
the resulting datetime will always be converted to the session defined
timezone, e.g.:
```
SELECT DATETIME_PARSE('2020-05-04 10:20:30.123 +02:00', 'HH:mm:ss dd/MM/uuuu VV') AS datetime;
```
with `time_zone` set to `-03:00` will result in
```

[7.x] Delay warning about missing x-pack (#56142)
* Delay warning about missing x-pack (#54265)

Currently, when monitoring is enabled in a freshly-installed cluster,
the non-master nodes log a warning message indicating that master may
not have x-pack installed. The message is often printed even when the
master does have x-pack installed but takes some time to setup the local
exporter for monitoring. This commit adds the local exporter setting
`wait_master.timeout` which defaults to 30 seconds. The setting
configures the time that the non-master nodes should wait for master to
setup monitoring. After the time elapses, they log a message to the user
about possible missing x-pack installation on master.

The logging of this warning was moved from `resolveBulk()` to
`openBulk()` since `resolveBulk()` is called only on cluster updates and
the message might not be logged until a new cluster update occurs.

Closes #40898

David Turner 69f50fe79f Improve same-shard allocation explanations (#56010)
I see occasional confusion about the explanations emitted by the same-shard
allocation decider, particularly amongst new users setting up a single-node
cluster and trying to determine why their cluster has `yellow` health. For
example:

    the shard cannot be allocated to the same node on which a copy of the shard
    already exists

This is technically correct but it's quite a complicated sentence. Also, by
starting with "the shard cannot be allocated" it makes it sound like this is
the problem, whereas in fact this message is a good thing and users should
typically focus their attention elsewhere.

This commit simplifies the wording of these messages and makes them sound more
positive, for example:

    a copy of this shard is already allocated to this node

Filtering out throttled indices made sense a couple years ago, but as
we're now improving support for slow requests with `_async_search` and
exploring ways to reduce storage costs, this feature has most likely
become a trap, that we'd like to not have with upcoming features that
would use search throttling.

[ML] Add effective max model memory limit to ML info (#55581)
The ML info endpoint returns the max_model_memory_limit setting
if one is configured.  However, it is still possible to create
a job that cannot run anywhere in the current cluster because
no node in the cluster has enough memory to accommodate it.

This change adds an extra piece of information,
limits.effective_max_model_memory_limit, to the ML info
response that returns the biggest model memory limit that could
be run in the current cluster assuming no other jobs were
running.

The idea is that the ML UI will be able to warn users who try to
create jobs with higher model memory limits that their jobs will
not be able to start unless they add a bigger ML node to their
cluster.

Adds a "node" field to the response from the following endpoints:

1. Open anomaly detection job
2. Start datafeed
3. Start data frame analytics job

If the job or datafeed is assigned to a node immediately then
this field will return the ID of that node.

In the case where a job or datafeed is opened or started lazily
the node field will contain an empty string.  Clients that want
to test whether a job or datafeed was opened or started lazily
can therefore check for this.

[ML] partitions model definitions into chunks (#55260) (#55484)
This paves the data layer way so that exceptionally large models are partitioned across multiple documents.

This change means that nodes before 7.8.0 will not be able to use trained inference models created on nodes on or after 7.8.0.

I chose the definition document limit to be 100. This *SHOULD* be plenty for any large model. One of the largest models that I have created so far had the following stats:
~314MB of inflated JSON, ~66MB when compressed, ~177MB of heap.
With the chunking sizes of `16 * 1024 * 1024` its compressed string could be partitioned to 5 documents.
Supporting models 20 times this size (compressed) seems adequate for now.

[7.x] Add prefer_v2_templates flag and index setting (#55411) (#55476)
This commit adds a new querystring parameter on the following APIs:
- Index
- Update
- Bulk
- Create Index
- Rollover

These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference
creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be
changed to `true` for 8.0+ in subsequent work.

Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting.
This setting is used so that actions that automatically create a new index (things like rollover
initiated by ILM) will inherit the preference from the original index. This setting is dynamic so
that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias
performing periodic rollover.

This also adds support for sending this parameter to the High Level Rest Client.

Deprecate disabling basic-license features (#54816) (#55405)
We believe there's no longer a need to be able to disable basic-license
features completely using the "xpack.*.enabled" settings. If users don't
want to use those features, they simply don't need to use them. Having
such features always available lets us build more complex features that
assume basic-license features are present.

This commit deprecates settings of the form "xpack.*.enabled" for
basic-license features, excluding "security", which is a special case.
It also removes deprecated settings from integration tests and unit
tests where they're not directly relevant; e.g. monitoring and ILM are
no longer disabled in many integration tests.

Implement the use of scalar functions inside aggregate functions.

```
SELECT MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) AS max, b
FROM test
GROUP BY b
HAVING MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) > 5
```

Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as
this is currently not implemented on the ElasticSearch side.

[7.x] [ML] adding prediction_field_type to inference config (#55128) (#55230)
* [ML] adding prediction_field_type to inference config (#55128)

Data frame analytics dynamically determines the classification field type. This field type then dictates the encoded JSON that is written to Elasticsearch. 

Inference needs to know about this field type so that it may provide the EXACT SAME predicted values as analytics. 

Here is added a new field `prediction_field_type` which indicates the desired type. Options are: `string` (DEFAULT), `number`, `boolean` (where close_to(1.0) == true, false otherwise). 

Analytics provides the default `prediction_field_type` when the model is created from the process.

value_count Aggregation optimization (backport of #54854) (#55076)
We found some problems during the test.

Data: 200Million docs, 1 shard, 0 replica

    hits    |   avg   |   sum   | value_count |
----------- | ------- | ------- | ----------- |
     20,000 |   .038s |   .033s |       .063s |
    200,000 |   .127s |   .125s |       .334s |
  2,000,000 |   .789s |   .729s |      3.176s |
 20,000,000 |  4.200s |  3.239s |     22.787s |
200,000,000 | 21.000s | 22.000s |    154.917s |

The performance of `avg`, `sum` and other is very close when performing
statistics, but the performance of `value_count` has always been poor,
even not on an order of magnitude. Based on some common-sense knowledge,
we think that `value_count` and sum are similar operations, and the time
consumed should be the same. Therefore, we have discussed the agg
of `value_count`.

The principle of counting in es is to traverse the field of each
document. If the field is an ordinary value, the count value is
increased by 1. If it is an array type, the count value is increased
by n. However, the problem lies in traversing each document and taking
out the field, which changes from disk to an object in the Java
language. We summarize its current problems with Elasticsearch as:

- Number cast to string overhead, and GC problems caused by a large
  number of strings
- After the number type is converted to string, sorting and other
  unnecessary operations are performed

Here is the proof of type conversion overhead.

particularly serious.

Our optimization code is actually very simple. It is to manage different
types separately, instead of uniformly converting to string unified
processing. We added type identification in ValueCountAggregator, and
made special treatment for number and geopoint types to cancel their
type conversion. Because the string type is reduced and the string
constant is reduced, the improvement effect is very obvious.

- The results are more in line with common sense. `value_count` is about
  the same as `avg`, `sum`, etc., or even lower than these. Previously,
  `value_count` was much larger than avg and sum, and it was not even an
  order of magnitude when the amount of data was large.
- When calculating numeric types such as `double` and `long`, the
  performance is improved by about 8 to 9 times; when calculating the
  `geo_point` type, the performance is improved by 18 to 20 times.

Improve total build configuration time (#54611) (#54994)
This commit includes a number of changes to reduce overall build
configuration time. These optimizations include:

- Removing the usage of the 'nebula.info-scm' plugin. This plugin
   leverages jgit to load read various pieces of VCS information. This
   is mostly overkill and we have our own minimal implementation for
   determining the current commit id.
- Removing unnecessary build dependencies such as perforce and jgit
   now that we don't need them. This reduces our classpath considerably.
- Expanding the usage lazy task creation, particularly in our
   distribution projects. The archives and packages projects create
   lots of tasks with very complex configuration. Avoiding the creation
   of these tasks at configuration time gives us a nice boost.

EQL functions are an easy way for users to transform indexed data

Users can circumvent this by indexing fields containing the transformed
data, but that usually slows index speeds.

This adds a related tip and example covering these tradeoffs.

Tanguy Leroux dea8a31480 Wait for Active license before running CCR API tests (#53966)
DocsClientYamlTestSuiteIT sometimes fails for CCR 
related tests because tests are started before the license 
is fully applied and active within the cluster. The first 
tests to be executed then fails with the error noticed 
in #53430. This can be easily reproduced locally by 
only running CCR docs tests.

This commit adds some @Before logic in 
DocsClientYamlTestSuiteIT so that it waits for the 
license to be active before running CCR tests.

[ML] Introduce a "starting" datafeed state for lazy jobs (#54065)
It is possible for ML jobs to open lazily if the "allow_lazy_open"
option in the job config is set to true.  Such jobs wait in the
"opening" state until a node has sufficient capacity to run them.

This commit fixes the bug that prevented datafeeds for jobs lazily
waiting assignment from being started.  The state of such datafeeds
is "starting", and they can be stopped by the stop datafeed API
while in this state with or without force.

Add heuristics to compute pre_filter_shard_size when unspecified (#53873) (#54007)
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.

Backport of async search changes (#53976)
* Get Async Search: omit _clusters section when empty (#53907)

The _clusters section is omitted by the search API whenever no remote clusters are searched. Async search should do the same, but Get Async Search returns a deserialized response, hence a weird `_clusters` section with all values set to `0` gets returned instead. In fact the recreated Clusters object is not the same object as the EMPTY constant, yet it has the same content.

This commit addresses this by changing the comparison in the `toXContent` method to not print out the section if the number of total clusters is `0`.

* Async search: remove version from response (#53960)

The goal of the version field was to quickly show when you can expect to find something new in the search response, compared to when nothing has changed. This can also be done by looking at the `_shards` section and `num_reduce_phases` returned with the search response. In fact when there has been one or more additional reduction of the results, you can expect new results in the search response. Otherwise, the `_shards` section could notify of additional failures of shards that have completed the query, but that is not a guarantee that their results will be exposed (only when the following partial reduction is performed their results will be available).

That said this commit clarifies this in the docs and removes the version field from the async search response

* Async Search: replicas to auto expand from 0 to 1 (#53964)

This way single node clusters that are green don't go yellow once async search is used, while
all the others still have one replica.

* [DOCS] address timing issue in async search docs tests (#53910)

The docs snippets for submit async search have proven difficult to test as it is not possible to guarantee that you get a response that is not final, even when providing `wait_for_completion=0`. In the docs we want to show though a proper long-running query, and its first response should be partial rather than final.

With this commit we adapt the docs snippets to show a partial response, and replace under the hood all that's needed to make the snippets tests succeed when we get a final response. Also, increased the timeout so we always get a final response.

This PR adds a temporary redirect for the docs page. This redirect

Tianlun Li e7ae9ae596 Deprecate delaying state recovery for master nodes (#53646)
It is useful to be able to delay state recovery until enough data nodes have
joined the cluster, since this gives the shard allocator a decent opportunity
to re-use as much existing data as possible. However we also have the option to
delay state recovery until a certain number of master-eligible nodes have
joined, and this is unnecessary: we require a majority of master-eligible nodes
for state recovery, and there is no advantage in waiting for more.

This commit deprecates the unnecessary settings in preparation for their
removal.

Cumulative backport of async search changes (#53635)
* Submit async search to work only with POST (#53368)

Currently the submit async search API can be called using both GET and POST at REST, but given that it submits a call and creates internal state, POST should be the only allowed method.

* Refine SearchProgressListener internal API (#53373)

The following cumulative improvements have been made:
- rename `onReduce` and `notifyReduce` to `onFinalReduce` and `notifyFinalReduce`
- add unit test for `SearchShard`
- on* methods in `SearchProgressListener` shouldn't need to be public as they should never be called directly, they only need to be overridden hence they can be made protected. They are actually called directly from a test which required some adapting, like making `AsyncSearchTask.Listener` class package private instead of private
- Instead of overriding `getProgressListener` in `AsyncSearchTask`, as it feels weird to override a getter method, added a specific method that allows to retrieve the Listener directly without needing to cast it. Made the getter and setter for the listener final in the base class.
- rename `SearchProgressListener#searchShards` methods to `buildSearchShards` and make it static given that it accesses no instance members
- make `SearchShard` and `SearchShardTask` classes final

* Move async search yaml tests to x-pack yaml test folder (#53537)

The yaml tests for async search currently sit in its qa folder. There is no reason though for them to live in a separate folder as they don't require particular setup. This commit moves them to the main folder together with the other x-pack yaml tests so that they will be run by the client test runners too.

* [DOCS] Add temporary redirect for async-search (#53454)

The following API spec files contain a link to a not-yet-created
async search docs page:

* [async_search.delete.json][0]
* [async_search.get.json][1]
* [async_search.submit.json][2]

The Elaticsearch-js client uses these spec files to create their docs.
This created a broken link in the Elaticsearch-js docs, which has broken
the docs build.

This PR adds a temporary redirect for the docs page. This redirect
should be removed when the actual API docs are added.

Backport of new wildcard field type (#53590)
* New wildcard field optimised for wildcard queries (#49993)

Indexes values using size 3 ngrams and also stores the full original as a binary doc value.
Wildcard queries operate by using a cheap approximation query on the ngram field followed up by a more expensive verification query using an automaton on the binary doc values.  Also supports aggregations and sorting.

Highlighters skip ignored keyword values (#53408) (#53604)
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
is an overall wrong behaviour to attempt to highlight something that was
ignored during indexing.

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

in ES for a long time now so the docs flag is misleading.

[ML][Inference] adds new default_field_map field to trained models (#53294) (#53419)
Adds a new `default_field_map` field to trained model config objects.

This allows the model creator to supply field map if it knows that there should be some map for inference to work directly against the training data.

The use case internally is having analytics jobs supply a field mapping for multi-field fields. This allows us to use the model "out of the box" on data where we trained on `foo.keyword` but the `_source` only references `foo`.

Implement hidden aliases (#52547)
This commit introduces hidden aliases. These are similar to hidden
indices, in that they are not visible by default, unless explicitly
specified by name or by indicating that hidden indices/aliases are
desired.

The new alias property, `is_hidden` is implemented similarly to
`is_write_index`, except that it must be consistent across all indices
with a given alias - that is, all indices with a given alias must
specify the alias as either hidden, or all specify it as non-hidden,
either explicitly or by omitting the `is_hidden` property.

Adrien Grand cb868d2f5e
Introduce a `constant_keyword` field. (#49713) (#53024)
This field is a specialization of the `keyword` field for the case when all
documents have the same value. It typically performs more efficiently than
keywords at query time by figuring out whether all or none of the documents
match at rewrite time, like `term` queries on `_index`.

The name is up for discussion. I liked including `keyword` in it, so that we
still have room for a `singleton_numeric` in the future. However I'm unsure
whether to call it `singleton`, `constant` or something else, any opinions?

For this field there is a choice between
 1. accepting values in `_source` when they are equal to the value configured
    in mappings, but rejecting mapping updates
 2. rejecting values in `_source` but then allowing updates to the value that
    is configured in the mapping
This commit implements option 1, so that it is possible to reindex from/to an
index that has the field mapped as a keyword with no changes to the source.

Add validation for dynamic templates (#52890)
Backport of #51233 to the seven dot x branch.

Tries to load a `Mapper` instance for the mapping snippet of a dynamic template.
This should catch things like using an analyzer that is undefined or mapping attributes that are unused.

This is best effort:
* If `{{name}}` placeholder is used in the mapping snippet then validation is skipped.
* If `match_mapping_type` is not specified then validation is performed for all mapping types.
  If parsing succeeds with a single mapping type then this the dynamic mapping is considered valid.

If is detected that a dynamic template mapping snippet is invalid at mapping update time then the mapping update is failed for indices created on 8.0.0-alpha1 and later. For indices created on prior version a deprecation warning is omitted instead. In 7.x clusters the mapping update will never fail in case of an invalid dynamic template mapping snippet and a deprecation warning will always be omitted.

Closes #17411
Closes #24419

[ML] Add indices_options to datafeed config and update (#52793) (#52905)
This adds a new configurable field called `indices_options`. This allows users to create or update the indices_options used when a datafeed reads from an index.

This is necessary for the following use cases:
 - Reading from frozen indices
 - Allowing certain indices in multiple index patterns to not exist yet

These index options are available on datafeed creation and update. Users may specify them as URL parameters or within the configuration object.

Adds recall@k metric to rank eval API (#52889)
This change adds the recall@k metric and refactors precision@k to match
the new metric.

Recall@k is an important metric to use for learning to rank (LTR)
use-cases. Candidate generation or first ranking phase ranking functions
are often optimized for high recall, in order to generate as many
relevant candidates in the top-k as possible for a second phase of
ranking. Adding this metric allows tuning that base query for LTR.

David Turner 69b78f7f8a "Adding nodes" instructions only work on localhost (#52677)
The introductory sections of the reference manual contains some simplified
instructions for adding a node to the cluster. Unfortunately they are a little
too simplified and only really work for clusters running on `localhost`. If you
try and follow these instructions for a distributed cluster then the new node
will, confusingly, auto-bootstrap itself into a distinct one-node cluster.

Multiple nodes running on localhost is a valid config, of course, but we should
spell out that these instructions are really only for experimentation and that
it takes a bit more work to add nodes to a distributed cluster. This commit
does so.

Also, the "important config" instructions for discovery say that you MUST set
`discovery.seed_hosts` whereas in fact it is fine to ignore this setting and
use a dynamic discovery mechanism instead. This commit weakens this statement
and links to the docs for dynamic discovery mechanisms.

Finally, this section is also overloaded with some technical details that are
not important for this context and are adequately covered elsewhere, and
completely fails to note that the default discovery port is 9300. This commit
addresses this.

[7.x] Smarter copying of the rest specs and tests (#52114) (#52798)
* 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
  }
}

[ML] Adds feature importance to option to inference processor (#52218) (#52666)
This adds machine learning model feature importance calculations to the inference processor.

The new flag in the configuration matches the analytics parameter name: `num_top_feature_importance_values`
Example:
```
"inference": {
   "field_mappings": {},
   "model_id": "my_model",
   "inference_config": {
      "regression": {
         "num_top_feature_importance_values": 3
      }
   }
}
```

This will write to the document as follows:
```
"inference" : {
   "feature_importance" : {
      "FlightTimeMin" : -76.90955548511226,
      "FlightDelayType" : 114.13514762158526,
      "DistanceMiles" : 13.731580450792187
   },
   "predicted_value" : 108.33165831875137,
   "model_id" : "my_model"
}
```

This is done through calculating the [SHAP values](https://arxiv.org/abs/1802.03888).

It requires that models have populated `number_samples` for each tree node. This is not available to models that were created before 7.7.

Additionally, if the inference config is requesting feature_importance, and not all nodes have been upgraded yet, it will not allow the pipeline to be created. This is to safe-guard in a mixed-version environment where only some ingest nodes have been upgraded.

NOTE: the algorithm is a Java port of the one laid out in ml-cpp: https://github.com/elastic/ml-cpp/blob/master/lib/maths/CTreeShapFeatureImportance.cc

Updates the cross-cluster search (CCS) documentation to note how
cluster-level settings are applied.

When `ccs_minimize_roundtrips` is `true`, each cluster applies its own
cluster-level settings to the request.

When `ccs_minimize_roundtrips` is `false`, cluster-level settings for
the local cluster is used. This includes shard limit settings, such as
`action.search.shard_count.limit`, `pre_filter_shard_size`, and
`max_concurrent_shard_requests`. If these limits are set too low, the
request could be rejected.

Implement top_metrics agg (#51155) (#52366)
The `top_metrics` agg is kind of like `top_hits` but it only works on
doc values so it *should* be faster.

At this point it is fairly limited in that it only supports a single,
numeric sort and a single, numeric metric. And it only fetches the "very
topest" document worth of metric. We plan to support returning a
configurable number of top metrics, requesting more than one metric and
more than one sort. And, eventually, non-numeric sorts and metrics. The
trick is doing those things fairly efficiently.

  - Fuzzy queries
  - Regexp queries
  - Prefix queries (without index_prefixes enabled
  - Wildcard queries
  - Range queries on text and keyword fields
- Joining queries
  - HasParent queries
  - HasChild queries
  - ParentId queries
  - Nested queries
- Queries on deprecated 6.x geo shapes (using PrefixTree implementation)
- Queries that may have a high per-document cost:
  - Script score queries

[7.x] Permit EQL feature flag in release builds (#52201) (#52214)
7.x backport of #52201

Provides a path to set register the EQL feature flag in release builds.
This enables EQL in release builds so that release docs tests pass.

Release docs tests do not have infrastructure in place to only register
snippets from included portions of the docs, they instead include all
docs snippets.

Since EQL can not be enabled in release builds, this meant that the EQL
snippets fail in the release docs tests.

This adds the ability to enable EQL in the release docs tests. This
system property will be removed when EQL is ready for release.

David Turner 00b9098250 Ignore timeouts with single-node discovery (#52159)
Today we use `cluster.join.timeout` to prevent nodes from waiting indefinitely
if joining a faulty master that is too slow to respond, and
`cluster.publish.timeout` to allow a faulty master to detect that it is unable
to publish its cluster state updates in a timely fashion. If these timeouts
occur then the node restarts the discovery process in an attempt to find a
healthier master.

In the special case of `discovery.type: single-node` there is no point in
looking for another healthier master since the single node in the cluster is
all we've got. This commit suppresses these timeouts and instead lets the node
wait for joins and publications to succeed no matter how long this might take.

[7.x] Allow forcemerge in the hot phase for ILM policies (#520… (#52083)
* Allow forcemerge in the hot phase for ILM policies

This commit changes the `forcemerge` action to also be allowed in the `hot` phase for policies. The
forcemerge will occur after a rollover, and allows users to take advantage of higher disk speeds for
performing the force merge (on a separate node type, for example).

On caveat with this is that a `forcemerge` in the `hot` phase *MUST* be accompanied by a `rollover`
action. ILM validates policies to ensure this is the case.

Resolves #43165

* Use anyMatch instead of findAny in validation

* Make randomTimeseriesLifecyclePolicy single-pass

Introduce jvm.options.d for customizing JVM options (#51882)
This commit introduces the ability to override JVM options by adding
custom JVM options files to a jvm.options.d directory. This simplifies
administration of Elasticsearch by not requiring administrators to keep
the root jvm.options file in sync with changes that we make to the root
jvm.options file. Instead, they are not expected to modify this file but
instead supply their own in jvm.options.d. In Docker installations, this
means they can bind mount this directory in. In future versions of
Elasticsearch, we can consider removing the root jvm.options file
(instead, providing all options there as system JVM options).

Permit autoscaling feature flag in release builds (#52088)
This commit provides a path to set register the autoscaling feature flag

tests can pass. Our release docs tests do not have infrastructure in
place to only register snippets from included portions of the docs, they
instead include all docs snippets. Since autoscaling can not be enabled
in release builds, this meant that the autoscaling snippets would fail
in the release docs tests. To address then, we need the ability to
enable autoscaling in the release docs tests which we can now do with
the system property added here. This system property will be removed
when autoscaling is ready for release.

The main purpose of this commit is to add a single autoscaling REST

than commiting a fully-functioning autoscaling API, we introduce here
the skeleton so that we can start wiring up the build and testing
infrastructure, establish security roles/permissions, an so on. This
way, in a forthcoming PR that introduces actual functionality, that PR
will be smaller and have less distractions around that sort of
infrastructure.

Currently the rounding used in range queries can behave differently for `date`

the one we document in https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-range-query.html#range-query-date-math-rounding.
This change adapts the rounding behaviour for RangeType.DATE so it uses the
same logic as the `date` for the `date_range` type.

Warnings are added for when:
* A realm does not have an order config
* Multiple realms have the same order config

The warning messages are added to both deprecation API and loggings.
The main reasons for doing this are: 1) there is currently no automatic relay
between the two; 2) deprecation API is under basic and we need logging

Marios Trivyzas f373020349 SQL: Fix ORDER BY YEAR() function (#51562)
Previously, if YEAR() was used as and ORDER BY argument without being
wrapped with another scalar (e.g. YEAR(birth_date) + 10), no script
ordering was used but instead the underlying field (e.g. birth_date)
was used instead as a performance optimisation. This works correctly if
YEAR() is the only ORDER BY arg but if further args are used as tie
breakers for the ordering wrong results are produced. This is because
2 rows with the different birth_date but on the same year are not tied
as the underlying ordering is on birth_date and not on the
YEAR(birth_date), and the following ORDER BY args are ignored.

Remove this optimisation for YEAR() to avoid incorrect results in
such cases.

As a consequence another bug is revealed: scalar functions on top
of nested fields produce scripted sorting/filtering which is not yet
supported. In such cases no error was thrown but instead all values for
such nested fields were null and were passed to the script implementing
the sorting/filtering, producing incorrect results.

Detect such cases and throw a validation exception.

Deprecate timeout.tcp_read AD/LDAP realm setting (#47305)
The timeout.tcp_read AD/LDAP realm setting, despite the low-level
allusion, controls the time interval the realms wait for a response for
a query (search or bind). If the connection to the server is synchronous
(un-pooled) the response timeout is analogous to the tcp read timeout.
But the tcp read timeout is irrelevant in the common case of a pooled
connection (when a Bind DN is specified).

The timeout.tcp_read qualifier is hereby deprecated in favor of
timeout.response.

In addition, the default value for both timeout.tcp_read and
timeout.response is that of timeout.ldap_search, instead of the 5s (but
the default for timeout.ldap_search is still 5s). The
timeout.ldap_search defines the server-controlled timeout of a search
request. There is no practical use case to have a smaller tcp_read
timeout compared to ldap_search (in this case the request would time-out
on the client but continue to be processed on the server). The proposed
change aims to simplify configuration so that the more common
configuration change, adjusting timeout.ldap_search up, has the expected
result (no timeout during searches) without any additional
modifications.

The docs tests have recently been running much slower than before (see #49753).

tests to run much slower.

Password-protected Keystore Feature Branch PR (#51123) (#51510)
* Reload secure settings with password (#43197)

If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.

* Add passphrase support to elasticsearch-keystore (#38498)

This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.

Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores

When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.

When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase

Passphrase can be set to be empty when changing/setting it for an
existing keystore

Relates to: #32691
Supersedes: #37472

* Restore behavior for force parameter (#44847)

Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.

*  Handle pwd protected keystores in all CLI tools  (#45289)

This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.

* Modify docs for setup passwords and saml metadata cli (#45797)

Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)

This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.

The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)

In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.

In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.

A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.

* Adjust docs for password protected keystore (#45054)

This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.

* Fix failing Keystore Passphrase test for feature branch (#50154)

One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.

It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.

* Run keystore management tests on docker distros (#50610)

* Add Docker handling to PackagingTestCase

Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.

* Improve ES startup check for docker

Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.

* Test password-protected keystore with Docker (#50803)

This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.

We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.

* Add documentation for keystore startup prompting (#50821)

When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)

For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.

* Restore handling of string input

Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null

* Apply spotless reformatting

* Use '--since' flag to get recent journal messages

When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.

Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.

It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.

Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Use new journald wrapper pattern

* Update version added in secure settings request

Enable tests in FIPS 140 in JDK 11 (#49485)
This change changes the way to run our test suites in 
JVMs configured in FIPS 140 approved mode. It does so by:

- Configuring any given runtime Java in FIPS mode with the bundled
policy and security properties files, setting the system
properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.

- When runtime java is 11 and higher, using BouncyCastle FIPS 
Cryptographic provider and BCJSSE in FIPS mode. These are 
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests

- When runtime java is 8, using BouncyCastle FIPS 
Cryptographic provider and SunJSSE in FIPS mode. 

Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

Initial autoscaling commit (#51161)
This commit merely adds the skeleton for the autoscaling project, adding
the basics to include the autoscaling module in the default
distribution, opt-in to code formatting, and a placeholder for the docs.

Introduce hidden indices (#51164)
This change introduces a new feature for indices so that they can be
hidden from wildcard expansion. The feature is referred to as hidden
indices. An index can be marked hidden through the use of an index
setting, `index.hidden`, at creation time. One primary use case for
this feature is to have a construct that fits indices that are created
by the stack that contain data used for display to the user and/or
intended for querying by the user. The desire to keep them hidden is
to avoid confusing users when searching all of the data they have
indexed and getting results returned from indices created by the
system.

Hidden indices have the following properties:
* API calls for all indices (empty indices array, _all, or *) will not
  return hidden indices by default.
* Wildcard expansion will not return hidden indices by default unless
  the wildcard pattern begins with a `.`. This behavior is similar to
  shell expansion of wildcards.
* REST API calls can enable the expansion of wildcards to hidden
  indices with the `expand_wildcards` parameter. To expand wildcards
  to hidden indices, use the value `hidden` in conjunction with `open`
  and/or `closed`.
* Creation of a hidden index will ignore global index templates. A
  global index template is one with a match-all pattern.
* Index templates can make an index hidden, with the exception of a
  global index template.
* Accessing a hidden index directly requires no additional parameters.

[7.x][ML] DF Analytics _explain API should skip object fields (#51115) (#51147)
Object fields cannot be used as features. At the moment _explain
API includes them and even worse it allows it does not error when
an object field is excluded. This creates the expectation to the
user that all children fields will also be excluded while it's not
the case.

This commit omits object fields from the _explain API and also
adds an error if an object field is included or excluded.

James Rodewig b6bf64b969 [DOCS] Collapse node stats response sections (#51063)
elastic/docs#1687 added support for the `[%collapsible]` Asciidoc
attribute, which creates collapsible sections in the HTML output.

This PR makes two related changes to the nodes stats API documentation:

* Makes the response parameter sections collapsible. This allows users
  to more easily navigate the page without long walls of text.

* Reorders the response parameter sections to match the default order
  returned by the API.

Relates to #47524.

James Rodewig 7ef906fde8 [DOCS] Add tutorials section to analysis topic (#50809)
Adds a 'Configure text analysis' page to house tutorial content for the
analysis topic.

Also relocates the following pages as children as this new page:

* 'Test an analyzer'
* 'Configuring built-in analyzers'
* 'Create a custom analyzer'

I plan to add a tutorial for specifying index-time and search-time
analyzers to this section as part of a future PR.

https://www.elastic.co/guide/en/machine-learning/7.5/ml-concepts.html

This PR only includes the 'Anatomy of an analyzer' page as a 'Concepts'
child page, but I plan to add other concepts, such as 'Index time vs.
search time', with later PRs.
