Bulk Request in High level rest client should be consistent with what is
possible in Rest API, therefore should support global parameters. Global
parameters are passed in URL in Rest API.
Some parameters are mandatory - index, type - and would fail validation
if not provided before before the bulk is executed.
Optional parameters - routing, pipeline.
The usage of these should be consistent across sync/async execution,
bulk processor and BulkRequestBuilder
closes#26026
Deprecates `_source_include` and `_source_exclude` url parameters

Adds checks for misbehaving parsers. The checks aren't perfect at all but
they are simple and fast enough that we can do them all the time so
they'll catch most badly behaving parsers.
Closes#34351
In an effort to encapsulate different clients, the request converters
are being shuffled around. This splits the Index Lifecycle Management
request converters.
With the introduction of _ilm/stop and _ilm/start APIs, the
use cases where one would only target a select group
of indices to start/stop has been reduced. Since there is no
strong use-case for skipping specific indices, it is best to
remove this functionality and only adding if later desired, with the
hopes of keeping things more simple.
* Removes Set Policy API in favour of setting index.lifecycle.name
directly
* Reinstates matcher that will still be used
* Cleans up code after rebase
* Adds test to check changing policy with ndex settings works
* Fixes TimeseriesLifecycleActionsIT after API removal
* Fixes docs tests
* Fixes case on close where lifecycle service was never created
With the move to separate RequestConverters classes for each client,
some of the access restrictions on the new classes are more open than
the prior RequestConverters classes. This standardizes the
*RequestConverters classes as package-private, final, and with a private
constructor so that no instances of the can be inadvertently created.

Introduces client-specific request and response classes that do not
depend on the server
The `type` parameter is named `licenseType` in the response class to be
more descriptive. The parts that make up the acknowledged-required
response are given slightly different names than their server-response
types to be consistent with the naming in the put license API
Tests do not cover all cases because the integ test cluster starts up
with a trial license - this will be addressed in a future commit
This moves the rollup cleanup code for http tests from the high level rest
client into the test framework and then entirely removes the rollup cleanup
code for http tests that lived in x-pack. This is nice because it
consolidates the cleanup into one spot, automatically invokes the cleanup
without the test having to know that it is "about rollup", and should allow
us to run the rollup docs tests.

We added support for role mapper expression DSL in #33745,

This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.
This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.
Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.
Closes#32836
* HLRC: ML Add preview datafeed api
* Changing deprecation handling for parser
* Removing some duplication in docs, will address other APIs in another PR
This change adds throttling to the update-by-query and delete-by-query cases
similar to throttling for reindex. This mostly means additional methods on the
client class itself, since the request hits the same RestHandler, just with
slightly different endpoints, and also the return values are similar.
The PutUserRequest implemented closeable as it assumed ownership of the
password provided to the class. This change removes the ownership of
the password, documents it in the javadoc, and removes the closeable
implementation.
Additionally, the intermediate bytes used for writing the password to
XContent are now cleared. This makes the PutUserRequest consistent with
the behavior discussed in #33509.
Optionals containing boxed primitive types are prohibitively costly because they
have two level of boxing. For Optional<Integer> the analogous OptionalInt can be
used to avoid the boxing of the contained int value.
Adds support for the get rollup job to the High Level REST Client. I had
to do three interesting and unexpected things:
1. I ported the rollup state wiping code into the high level client
tests. I'll move this into the test framework in a followup and remove
the x-pack version.
2. The `timeout` in the rollup config was serialized using the
`toString` representation of `TimeValue` which produces fractional time
values which are more human readable but aren't supported by parsing. So
I switched it to `getStringRep`.
3. Refactor the xcontent round trip testing utilities so we can test
parsing of classes that don't implements `ToXContent`.
Now that all basic APIs for managing jobs and datafeeds have been
implemented we replace the duplicated `MlRestTestStateCleaner`
with an implementation that uses the HLRC Machine Learning client
itself.
This commit adds support for role mapping expression dsl.
Functionally it is similar to what we have on the server side
except for the rule evaluation which is not required on the client.
The role mapper expression can either be field expression or
composite expression of one or more expressions. Role mapper
expression parser is used to parse JSON DSL to list of expressions.
This forms the base for role mapping APIs (get, post/put and delete)
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
The high level Rest clients reindex method currently doesn't pass on the
"requests_per_second" that are optionally set in ReindexRequest through the Rest
layer. This change makes sure the value is added to the request parameters if
set and also includes it for the update-by-query and delete-by-query cases.
Using index settings for ILM state is fragile and exposes too much
information that doesn't need to be exposed. Using custom index metadata
is more resilient and allows more controlled access to internal
information.
As part of these changes, moves away from using defaults for ILM-related
values, in favor of using null values to clearly indicate that the value is not
present.
This commit adds the Create Rollup Job API to the high level REST
client. It supersedes #32703 and adds dedicated request/response
objects so that it does not depend on server side components.

This also changes both `DatafeedConfig` and `DatafeedUpdate`

Adds Request and Reponse classes for accessing lifecycle policies.

This change adds support for enable and disable user APIs to the high
level rest client. There is a common request base class for both
requests with specific requests that simplify the use of these APIs.
The response for these APIs is simply an empty object so a new response
class has been created for cases where we expect an empty response to
be returned.
Finally, the put user documentation has been moved to the proper
location that is not within an x-pack sub directory and the document
tags no longer contain x-pack.

The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
This removes `PhaseAfterStep` in favor of a new `PhaseCompleteStep`. This step
in only a marker that the `LifecyclePolicyRunner` needs to halt until the time
indicated for entering the next phase.
This also fixes a bug where phase times were encapsulated into the policy
instead of dynamically adjusting to policy changes.

This commit adds a security client to the high level rest client, which
includes an implementation for the put user api. As part of these
changes, a new request and response class have been added that are
specific to the high level rest client. One change here is that the response
was previously wrapped inside a user object. The plan is to remove this
wrapping and this PR adds an unwrapped response outside of the user
object so we can remove the user object later on.

With the switch to client side request and response objects, we need a
client side version of RefreshPolicy. This change adds a client side
version of RefreshPolicy along with a method to add it to the
parameters of a request. The existing method to add
WriteRequest.RefreshPolicy to the parameters of a request is now
deprecated.
There are many requests that allow the user to set a few timeouts
on. This class will allow requests impl'd in HLRC to extend from, and
allow users to set those values without significant work to add them to
every request.
The Validatable class comes from an old class in server code, that
assumed null was returned in the event of validation having no
errors. This commit changes that to use Optional, which is cleaner than
passing around null objects.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `client` and `distribution` projects to use
the new versions.
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
The HLRC has historically reused the same Request and Response classes
that the server module uses. This commit deprecates the use of any
server module Request and Response classes, and adds a small bit of
validation logic that differs from server slightly, in that it does not
assume a check for a null ValidationException class is not enough to
determine if validation failed.

This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```

All of the Elasticsearch logging infrastructure relies on log4j but we
don't want the high level rest client to rely on log4j2. All of its
logging goes through commons-logging because our dependencies drag in
commons logging already. Anyway, this bans direct use of Elasticsearch's
logging infrastructure in the high level REST client. It is still
possible to use it indirectly though and there isn't anything we can
really do about that until we split the high level rest client from
Elasticsearch's server jar.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This test is superfluous - it was added to address #32770 but it later turned out there was an existing test that just required a fix to provide the missing test coverage.

This commit adds back the publishing section that sets the artifact id
of the generated pom file for the high level rest client. This was
accidentally removed during a consolidationo of the shadow plugin logic.
We previously discussed moving the classes extending `AcknowledgedResponse` to
simply use `AcknowledgedResponse`, making the class non-abstract.
This moves the first class to do this, removing `WritePipelineResponse` in the
process.
If we like the way this looks, I will switch the remaining classes over to using
`AcknowledgedResponse`.
Since replica counts and allocation rules are set separately, it is not always clear how many replicas are to be allocated in the allocate action. Moving the replicas action to occur at the same time as the allocate action, resolves this confusion that could end an undesired state. This means that the ReplicasAction is removed, and a new optional replicas parameter is added to AllocateAction.
Suggestion responses were previously serialized as streamables which
made writing suggesters in plugins with custom suggestion response types
impossible. This commit makes them serialized as named writeables and
provides a facility for registering a reader for suggestion responses
when registering a suggester.
This also makes Suggestion responses abstract, requiring a suggester
implementation to provide its own types. Suggesters which do not need
anything additional to what is defined in Suggest.Suggestion should
provide a minimal subclass.
The existing plugin suggester integration tests are removed and
replaced with an equivalent implementation as an example
plugin.

The commercial clients were improperly placed into XPackClient, which is
a wrapper for the miscellaneous usage and info APIs. This commit moves
them into the HLRC.
This commit does the following:
- renames index-lifecycle plugin to ilm
- modifies the endpoints to ilm instead of index_lifecycle
- drops _xpack from the endpoints
- drops a few duplicate endpoints
This adds HLRC support for the ILM operation of setting an index's lifecycle
policy.
It also includes extracting and renaming a number of classes (like the request
and response objects) as well as the addition of a new `IndexLifecycleClient`
for the HLRC. This is a prerequisite to making the `index.lifecycle.name`
setting internal only, because we require a dedicated REST endpoint to change
the policy, and our tests currently set this setting with the REST client
multiple places. A subsequent PR will change the setting to be internal and move
those uses over to this new API.
This misses some links to the documentation because I don't think ILM has any
documentation available yet.

In the HL REST client we replace the License object with a string, because of

The notion of "quality" is an overloaded term in the search ranking evaluation
context. Its usually used to decribe certain levels of "good" vs. "bad" of a
seach result with respect to the users information need. We currently report the
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.
Currently the ranking evaluation response contains a 'unknown_docs' section
for each search use case in the evaluation set. It contains document ids for
results in the search hits that currently don't have a quality rating.
This change renames it to `unrated_docs`, which better reflects its purpose.

This implementation behaves like the current transport client, that you basically cannot configure a Watch POJO representation as an argument to the put watch API, but only a bytes reference.

This commit also changes the license type to trial, so that watcher is available in high level rest client tests.

Moves the customizations to the build to produce nice shadow jars and
javadocs into common build code, mostly BuildPlugin with a little into
the root build.gradle file. This means that any project that applies the
shadow plugin will automatically be set up just like the high level rest
client:
* The non-shadow jar will not be built
* The shadow jar will not have a "classifier"
* Tests will run against the shadow jar
* Javadoc will include all of the shadowed classes
* Service files in `META-INF/services` will be merged
We have been encountering name mismatches between API defined in our
REST spec and method names that have been added to the high-level REST
client. We should check this automatically to prevent furher mismatches,
and correct all the current ones.
This commit adds a test for this and corrects the issues found by it.

Make SnapshotInfo and CreateSnapshotResponse parsers lenient for backwards compatibility. Remove extraneous fields from CreateSnapshotRequest toXContent.
* Adds a new auto-interval date histogram
This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.
This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.

The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).
The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.

This commit adds the _xpack/usage api to the high level rest client.
Currently in the transport api, the usage data is exposed in a limited
fashion, at most giving one level of helper methods for the inner keys
of data, but then exposing thos subobjects as maps of objects. Rather
than making parsers for every set of usage data from each feature, this
PR exposes the entire set of usage data as a map of maps.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `client/rest-high-level` project to use the new
versions.
The `:x-pack:protocol` project is an implementation detail shared by the
xpack projects and the high level rest client and really doesn't deserve
its own maven coordinants and published javadoc. This change bundles
`:x-pack:protocol` into the high level rest client.
Relates to #29827
Originally I put the X-Pack info object into the top level rest client
object. I did that because we thought we'd like to squash `xpack` from
the name of the X-Pack APIs now that it is part of the default
distribution. We still kind of want to do that, but at least for now we
feel like it is better to keep the high level rest client aligned with
the other language clients like C# and Python. This shifts the X-Pack
info API to align with its json spec file.
Relates to #31870
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!
= Open source
The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.
The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.
= Location of the new files
We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.
We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.
= Location of the API in the REST client
We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.
`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.
= Jars, jars everywhere!
This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.
In that followup I'll address javadoc issues as well.
= Breaking-Java
This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.
This is a followup to #31537. It makes a number of changes requested by
a review that came after the PR was merged. These are mostly cleanups
and doc improvements.
This PR does the server side work for adding the Get Index API to the REST
high-level-client, namely moving resolving default settings to the
transport action. A follow up would be the client side changes.
