This PR adds deprecation warnings when accessing System Indices via the REST layer. At this time, these warnings are only enabled for Snapshot builds by default, to allow projects external to Elasticsearch additional time to adjust their access patterns.
Deprecation warnings will be triggered by all REST requests which access registered System Indices, except for purpose-specific APIs which access System Indices as an implementation detail a few specific APIs which will continue to allow access to system indices by default:
- `GET _cluster/health`
- `GET {index}/_recovery`
- `GET _cluster/allocation/explain`
- `GET _cluster/state`
- `POST _cluster/reroute`
- `GET {index}/_stats`
- `GET {index}/_segments`
- `GET {index}/_shard_stores`
- `GET _cat/[indices,aliases,health,recovery,shards,segments]`
Deprecation warnings for accessing system indices take the form:
```
this request accesses system indices: [.some_system_index], but in a future major version, direct access to system indices will be prevented by default
```
* Add System Indices check to AutoCreateIndex
By default, Elasticsearch auto-creates indices when a document is
submitted to a non-existent index. There is a setting that allows users
to disable this behavior. However, this setting should not apply to
system indices, so that Elasticsearch modules and plugins are able to
use auto-create behavior whether or not it is exposed to users.
This commit constructs the AutoCreateIndex object with a reference to
the SystemIndices object so that we bypass the check for the user-facing
autocreate setting when it's a system index that is being autocreated.
We also modify the logic in TransportBulkAction to make sure that if a
system index is included in a bulk request, we don't skip the
autocreation step.

Today some uncaught shard failures such as RejectedExecutionException skips the release of shard context
and let subsequent scroll requests access the same shard context again. Depending on how the other shards advanced,
this behavior can lead to missing data since scrolls always move forward.
In order to avoid hidden data loss, this commit ensures that we always release the context of shard search scroll requests whenever a failure
occurs locally. The shard search context will no longer exist in subsequent scroll requests which will lead to consistent shard failures
in the responses.
This change also modifies the retry tests of the reindex feature. Reindex retries scroll search request that contains a shard failure and
move on whenever the failure disappears. That is not compatible with how scrolls work and can lead to missing data as explained above.
That means that reindex will now report scroll failures when search rejection happen during the operation instead of skipping document
silently.
Finally this change removes an old TODO that was fulfilled with #61062.
There are currently half a dozen ways to add plugins and modules for
test clusters to use. All of them require the calling project to peek
into the plugin or module they want to use to grab its bundlePlugin
task, and then both depend on that task, as well as extract the archive
path the task will produce. This creates cross project dependencies that
are difficult to detect, and if the dependent plugin/module has not yet
been configured, the build will fail because the task does not yet
exist.
This commit makes the plugin and module methods for testclusters
symmetetric, and simply adding a file provider directly, or a project
path that will produce the plugin/module zip. Internally this new
variant uses normal configuration/dependencies across projects to get
the zip artifact. It also has the added benefit of no longer needing the
caller to add to the test task a dependsOn for bundlePlugin task.

Introduce a javaRestTest source set and task to compliment the yamlRestTest.
javaRestTest differs such that the code is sourced from Java and may have
different dependencies and setup requirements for the test clusters. This also
allows the tests to run in parallel in different cluster instances to prevent any
cross test contamination between the two types of tests.
Included in this PR is all :modules no longer use the integTest task. The tests
are now driven by test, yamlRestTest, javaRestTest, and internalClusterTest.
Since only :modules (and :rest-api-spec) have been converted to yamlRestTest
we can now disable the integTest task if either yamlRestTest or javaRestTest have
been applied. Once all projects are converted, we can delete the integTest task.

This commit adds the `require_alias` flag to requests that create new documents.
This flag, when `true` prevents the request from automatically creating an index. Instead, the destination of the request MUST be an alias.
When the flag is not set, or `false`, the behavior defaults to the `action.auto_create_index` settings.
This is useful when an alias is required instead of a concrete index.

The update by query action parses a script from an object (map or string). We will need to do the same for runtime fields as they are parsed as part of mappings (#59391).
This commit moves the existing parsing of a script from an object from RestUpdateByQueryAction to the Script class. It also adds tests and adjusts some error messages that are incorrect. Also, options were not parsed before and they are now. And unsupported fields are no longer silently ignored.
This commit moves the modules REST tests to the

* Create new data-stream xpack module.
* Move TimestampFieldMapper to the new module,
this results in storing a composable index template
with data stream definition only to work with default
distribution. This way data streams can only be used
with default distribution, since a data stream can
currently only be created if a matching composable index
template exists with a data stream definition.
* Renamed `_timestamp` meta field mapper
to `_data_stream_timestamp` meta field mapper.
* Add logic to put composable index template api
to fail if `_data_stream_timestamp` meta field mapper
isn't registered. So that a more understandable
error is returned when attempting to store a template
with data stream definition via the oss distribution.
In a follow up the data stream transport and
rest actions can be moved to the xpack data-stream module.
The commit makes the following changes:
* The timestamp field of a data stream definition in a composable
index template can only be set to '@timestamp'.
* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and
instead only check that the _timestamp field mapping has been defined on a backing index of a data stream.
* Moved code that injects _timestamp meta field mapping from `MetadataCreateIndexService#applyCreateIndexRequestWithV2Template58956(...)` method
to `MetadataIndexTemplateService#collectMappings(...)` method.
* Fixed a bug (#58956) that cases timestamp field validation to be performed
for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

This commit creates a new Gradle plugin to provide a separate task name
and source set for running YAML based REST tests. The only project
converted to use the new plugin in this PR is distribution/archives/integ-test-zip.
For which the testing has been moved to :rest-api-spec since it makes the most
sense and it avoids a small but awkward change to the distribution plugin.
The remaining cases in modules, plugins, and x-pack will be handled in followups.
This plugin is distinctly different from the plugin introduced in #55896 since
the YAML REST tests are intended to be black box tests over HTTP. As such they
should not (by default) have access to the classpath for that which they are testing.
The YAML based REST tests will be moved to separate source sets (yamlRestTest).
The which source is the target for the test resources is dependent on if this
new plugin is applied. If it is not applied, it will default to the test source
set.
Further, this introduces a breaking change for plugin developers that
use the YAML testing framework. They will now need to either use the new source set
and matching task, or configure the rest resources to use the old "test" source set that
matches the old integTest task. (The former should be preferred).
As part of this change (which is also breaking for plugin developers) the
rest resources plugin has been removed from the build plugin and now requires
either explicit application or application via the new YAML REST test plugin.
Plugin developers should be able to fix the breaking changes to the YAML tests
by adding apply plugin: 'elasticsearch.yaml-rest-test' and moving the YAML tests
under a yamlRestTest folder (instead of test)
This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.
The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

This change now also copies the op_type from the reindex request's destination index request to the actual index request being used in the bulk request.
For ensuring no document exists, the op_type create doesn't need to be copied, since Versions.MATCH_DELETED will copied from the 'mainRequest.getDestination().version()'.
The `version()` method on IndexRequest only returns Versions.MATCH_DELETED if op_type=create and no specific version has been specified.
However in order to be able to index into a data stream, the op_type must be create. So in order to support that the op_type must be copied from the reindex request's destination index request to the actual index request being used in the bulk request.

* Simplify java home verification
At one time, all uses of java home were found through the getJavaHome

refactorings ago, but the complex support for registering a java home
version needed that fails at configuration time still exists. The only
remaining use of grabbing java home is within bwc tests, and must be at

needed.
This commit consolidates the java home finding method into a utility

Closes#53137. Replace calls to deprecate(String,Object...) with deprecateAndMaybeLog(...), with an appropriate key, so that all messages

Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.
In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."
I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.
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.
This change converts the module and plugin parameters
for testClusters to be lazy. Meaning that the values
are not resolved until they are actually used. This
removes the requirement to use project.afterEvaluate to
be able to resolve the bundle artifact.
Note - this does not completely remove the need for afterEvaluate
since it is still needed for the custom resource extension.
This is a simple naming change PR, to fix the fact that "metadata" is a

naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.

Reindex would use timeValueNanos(System.nanoTime()). The intended use

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.
The block setup by the test could be released by the nodes cluster info
thread before the disk threshold decider was disabled, now disable
decider first.
We consider index level read_only_allow_delete blocks temporary since
the DiskThresholdMonitor can automatically release those when an index
is no longer allocated on nodes above high threshold.
The rest status has therefore been changed to 429 when encountering this
index block to signal retryability to clients.

including any deprecated and/or replaced combinations.

Previous behavior while copying HTTP headers to the ThreadContext,
would allow multiple HTTP headers with the same name, handling only
the first occurrence and disregarding the rest of the values. This
can be confusing when dealing with multiple Headers as it is not
obvious which value is read and which ones are silently dropped.
According to RFC-7230, a client must not send multiple header fields
with the same field name in a HTTP message, unless the entire field
value for this header is defined as a comma separated list or this
specific header is a well-known exception.
This commits changes the behavior in order to be more compliant to
the aforementioned RFC by requiring the classes that implement
ActionPlugin to declare if a header can be multi-valued or not when
registering this header to be copied over to the ThreadContext in
ActionPlugin#getRestHeaders.
If the header is allowed to be multivalued, then all such headers
are read from the HTTP request and their values get concatenated in
a comma-separated string.
If the header is not allowed to be multivalued, and the HTTP
request contains multiple such Headers with different values, the
request is rejected with a 400 status.
As types are no longer used in index requests, we can remove the type parameter
from `prepareIndex` methods in the `Client` interface. However, just changing the signature
of `prepareIndex(index, type, id)` to `prepareIndex(index, id)` risks confusion when
upgrading with the previous (now removed) `prepareIndex(index, type)` method -
just changing the dependency version of java code would end up silently changing the
semantics of the method call. Instead we should just remove this method entirely, and
replace it by calling `prepareIndex(index).setId(id)`
Types are no longer used in IndexRequest, DeleteRequest or UpdateRequest;
this commit removes them from the prepareX(index, type) methods on Client, as well as removing setType() and deprecated constructors on XRequestBuilder objects.

There were a small number of places where it didn't make sense to me to

`waitUntil`. This was partly to better reflect its usage, and partly so
that anyone trying to add a new call to awaitBusy wouldn't be able to find
it.

When using auto-generated IDs + the ingest drop processor (which looks to be used by filebeat
as well) + coordinating nodes that do not have the ingest processor functionality, this can lead
to a NullPointerException.
The issue is that markCurrentItemAsDropped() is creating an UpdateResponse with no id when
the request contains auto-generated IDs. The response serialization is lenient for our
REST/XContent format (i.e. we will send "id" : null) but the internal transport format (used for
communication between nodes) assumes for this field to be non-null, which means that it can't
be serialized between nodes. Bulk requests with ingest functionality are processed on the
coordinating node if the node has the ingest capability, and only otherwise sent to a different
node. This means that, in order to reproduce this, one needs two nodes, with the coordinating
node not having the ingest functionality.

Closes#19069. This method tries to summarize an exception in a single

In some cases, I rearranged some message formats so that exceptions are
reported at the end of the message, instead of in the middle.
Other changes:
* Rewrite DetailedErrorsEnabledIT to parse responses. Instead of relying
on substring matching, parse the response JSON and check fields
explicitly. This uses Jackson, which has been added to the build
dependencies for :qa:smoke-test-http.
* Add a getter to `VerificationFailure` so that the `cause` field can be
accessed and added as suppressed exceptions elsewhere.
Currently there are two issues with serializing BulkByScrollResponse.
First, when deserializing from XContent, indexing exceptions and search
exceptions are switched. Additionally, search exceptions do no retain
the appropriate RestStatus code, so you must evaluate the status code
from the exception. However, the exception class is not always correctly
retained when serialized.
This commit adds tests in the failure case. Additionally, fixes the
swapping of failure types and adds the rest status code to the search
failure.
The client and remote hit sources had each their own retry mechanism,
which would do the same. Supporting resiliency we would have to expand
on the retry mechanisms and as a preparation for that, the retry
mechanism is now shared such that each sub class is only responsible for
sending requests and converting responses/failures to common format.

Currently the process to execute a reindex process is tightly coupled to
step of initializing the task state. This creates problems when this
process is asynchronous. It is possible that the task state has not been
initialized which prevents follow-up actions such as rethrottle. This
commit separates the task initialization so that it can be executed as a
first step in the persistent reindex process.
This commit extracts the reindexing logic from the transport action so
that it can be incorporated into the persistent reindex work without
requiring the usage of the client.
With this change, we will return primary_term and seq_no of the current

Action is a class that encapsulates meta information about an action
that allows it to be called remotely, specifically the action name and
response type. With recent refactoring, the action class can now be
constructed as a static constant, instead of needing to create a
subclass. This makes the old pattern of creating a singleton INSTANCE
both misnamed and lacking a common placement.
This commit renames Action to ActionType, thus allowing the old INSTANCE
naming pattern to be TYPE on the transport action itself. ActionType
also conveys that this class is also not the action itself, although
this change does not rename any concrete classes as those will be
removed organically as they are converted to TYPE constants.

`TransportIndicesExistsAction` as well as its corresponding request,
request builder, response, and action.
Currently the fromXContent logic for reindex requests is implemented in
the rest action. This is inconsistent with other requests where the
logic is implemented in the request. Additionally, it requires access to
the rest action in order to parse the request. This commit moves the
logic and tests into the ReindexRequest.
A search request that partially fails with failures without an index
(index: null) in the failure would cause a parse error in reindex from
remote. This would hide the original exception, making it hard to debug
the root cause. This commit fixes this so that we can tolerate null
index entries in a search failure.
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.
