The `requires_replica` yaml test feature hasn't worked for years. This
is what happens if you try to use it:
```
> Throwable #1: java.lang.NullPointerException
> at __randomizedtesting.SeedInfo.seed([E6602FB306244B12:6E341069A8D826EA]:0)

> at org.elasticsearch.test.rest.yaml.section.SkipSection.skip(SkipSection.java:144)
> at org.elasticsearch.test.rest.yaml.ESClientYamlSuiteTestCase.test(ESClientYamlSuiteTestCase.java:321)
```
None of our tests use it.
TransportAction has many variants of execute. One of those variants
executes by returning a future, which is then often blocked on by
calling get(). This commit removes this variant of execute, instead
using a helper method for tests that want to block, or having tests
pass in a PlainActionFuture directly as a listener.

Given the weirdness of the response returned by the get alias API, we went for a client specific response, which allows us to hold the error message, exception and status returned as part of the response together with aliases. See #30536 .

Allows users of the Low Level REST client to specify which hosts a
request should be run on. They implement the `NodeSelector` interface
or reuse a built in selector like `NOT_MASTER_ONLY` to chose which nodes
are valid. Using it looks like:
```
Request request = new Request("POST", "/foo/_search");
RequestOptions options = request.getOptions().toBuilder();
options.setNodeSelector(NodeSelector.NOT_MASTER_ONLY);
request.setOptions(options);
...
```
This introduces a new `Node` object which contains a `HttpHost` and the
metadata about the host. At this point that metadata is just `version`
and `roles` but I plan to add node attributes in a followup. The
canonical way to **get** this metadata is to use the `Sniffer` to pull
the information from the Elasticsearch cluster.
I've marked this as "breaking-java" because it breaks custom
implementations of `HostsSniffer` by renaming the interface to
`NodesSniffer` and by changing it from returning a `List<HttpHost>` to a
`List<Node>`. It *shouldn't* break anyone else though.
Because we expect to find it useful, this also implements `host_selector`
support to `do` statements in the yaml tests. Using it looks a little
like:
```
---
"example test":
- skip:
features: host_selector
- do:
host_selector:
version: " - 7.0.0" # same syntax as skip
apiname:
something: true
```
The `do` section parses the `version` string into a host selector that
uses the same version comparison logic as the `skip` section. When the
`do` section is executed it passed the off to the `RestClient`, using
the `ElasticsearchHostsSniffer` to sniff the required metadata.
The idea is to use this in mixed version tests to target a specific
version of Elasticsearch so we can be sure about the deprecation
logging though we don't currently have any examples that need it. We do,
however, have at least one open pull request that requires something
like this to properly test it.
Closes#21888
This removes the abstract `getTranslog` method in `Engine`, instead leaving it
to the abstract implementations of the other methods that use the translog. This
allows future Engines not to have a Translog, as instead they must implement the
methods that use the translog pieces to return necessary values.
* Fully encapsulate LocalCheckpointTracker inside of the engine
This makes the Engine interface not expose the `LocalCheckpointTracker`, instead
exposing the pieces needed (like retrieving the local checkpoint) as individual
methods.
* Remove DocumentFieldMappers#simpleMatchToFullName, as it is duplicative of MapperService#simpleMatchToIndexNames.
* Rename MapperService#simpleMatchToIndexNames -> simpleMatchToFullName for consistency.
* Simplify EsIntegTestCase#assertConcreteMappingsOnAll to accept concrete fields instead of wildcard patterns.
This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
This commit adds a new writeBlobAtomic() method to the BlobContainer
interface that can be implemented by repository implementations which
support atomic writes operations.
When the BlobContainer implementation does not provide a specific
implementation of writeBlobAtomic(), then the writeBlob() method is used.

ObjectParser should throw XContentParseExceptions, not IAE. A dedicated parsing
exception can includes the place where the error occurred.
Closes#30605
With #31020 we introduced the ability for transport clients to indicate what features they support
in order to make sure we don't serialize object to them they don't support. This PR adapts the
serialization logic of persistent tasks to be aware of those features and not serialize tasks that
aren't supported.
Also, a version check is added for the future where we may add new tasks implementations and
need to be able to indicate they shouldn't be serialized both to nodes and clients.
As the implementation relies on the interface of `PersistentTaskParams`, these are no longer
optional. That's acceptable as all current implementation have them and we plan to make
`PersistentTaskParams` more central in the future.

This commit introduces the ability for a client to communicate to the
server features that it can support and for these features to be used in
influencing the decisions that the server makes when communicating with
the client. To this end we carry the features from the client to the
underlying stream as we carry the version of the client today. This
enables us to enhance the logic where we make protocol decisions on the
basis of the version on the stream to also make protocol decisions on
the basis of the features on the stream. With such functionality, the
client can communicate to the server if it is a transport client, or if
it has, for example, X-Pack installed. This enables us to support
rolling upgrades from the OSS distribution to the default distribution
without breaking client connectivity as we can now elect to serialize
customs in the cluster state depending on whether or not the client
reports to us using the feature capabilities that it can under these
customs. This means that we would avoid sending a client pieces of the
cluster state that it can not understand. However, we want to take care
and always send the full cluster state during node-to-node communication
as otherwise we would end up with different understanding of what is in
the cluster state across nodes depending on which features they reported
to have. This is why when deciding whether or not to write out a custom
we always send the custom if the client is not a transport client and
otherwise do not send the custom if the client is transport client that
does not report to have the feature required by the custom.

This change adds an option named `split_queries_on_whitespace` to the `keyword`
field type. When set to true full text queries (`match`, `multi_match`, `query_string`, ...) that target the field will split the input on whitespace to build the query terms. Defaults to `false`.
Closes#30393
This modifies the high level rest client to allow calling code to
customize per request options for the bulk API. You do the actual
customization by passing a `RequestOptions` object to the API call
which is set on the `Request` that is generated by the high level
client. It also makes the `RequestOptions` a thing in the low level
rest client. For now that just means you use it to customize the
headers and the `httpAsyncResponseConsumerFactory` and we'll add
node selectors and per request timeouts in a follow up.
I only implemented this on the bulk API because it is the first one
in the list alphabetically and I wanted to keep the change small
enough to review. I'll convert the remaining APIs in a followup.
This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
Include size of snapshot in snapshot metadata
Adds difference of number of files (and file sizes) between prev and current snapshot. Total number/size reflects total number/size of files in snapshot.
Closes#18543
Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps
the CompletableFuture but does not accept Throwable. This allows the
modification of netty and nio logic to no longer handle Throwable.
Today, the `ClusterApplier` and `MasterService` both use the
`ClusterStateTaskListener` interface to notify their callers when asynchronous
activities have completed. However, this is not wholly appropriate: none of the
callers into the `ClusterApplier` care about the `ClusterState` arguments that
they receive. This change introduces a dedicated ClusterApplyListener
interface for callers into the `ClusterApplier`, to distinguish these listeners
from the real `ClusterStateTaskListener`s that are waiting for responses from
the `MasterService`.
This commit reintroduces 31251c9 and 63a5799. These commits introduced a
memory leak and were reverted. This commit brings those commits back
and fixes the memory leak by removing unnecessary retain method calls.
This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.
Adding headers rather than setting them all at once seems more
user-friendly and we already do it in a similar way for parameters
(see Request#addParameter).
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should

This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
Date histograms on non-fixed timezones such as `Europe/Paris` proved much slower
than histograms on fixed timezones in #28727. This change mitigates the issue by
using a fixed time zone instead when shard data doesn't cross a transition so
that all timestamps share the same fixed offset. This should be a common case
with daily indices.
NOTE: Rewriting the aggregation doesn't work since the timezone is then also
used on the coordinating node to create empty buckets, which might be out of the
range of data that exists on the shard.
NOTE: In order to be able to get a shard context in the tests, I reused code
from the base query test case by creating a new parent test case for both
queries and aggregations: `AbstractBuilderTestCase`.
Mitigates #28727
This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- MovingFunctions.max()
- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
This change adds a `listTasks` method to the high level java
ClusterClient which allows listing running tasks through the
task management API.

A 6.x node can send a deprecation message that the default number of
shards will change from five to one in 7.0.0. In a mixed cluster,
whether or not a create index request sees five or one shard and
produces a deprecation message depends on the version of the master
node. This means that during BWC tests a test can see this deprecation
message depending on the version of the master node. In 6.x when we
introduced this deprecation message we assumed that whereever we see
this deprecation message is expected. However, in a mixed cluster test
we need a similar mechanism but it would only apply if the version of
the master node is earlier than 7.0.0. This commit takes advantage of a
recent change to expose the version of the master node to do sections of
REST tests. With this in hand, we can skip asserting on the deprecation
message if the version of the master node is before 7.0.0 and otherwise
seeing that deprecation message would be completely unexpected.
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
This commit exposes the master version to the REST test context. This
will be needed in a follow-up where the master version will be used to
determine whether or not a certain warning header is expected.
This configures all `qa` projects to use the distribution contained in
the `tests.distribution` system property if it is set. The goal is to
create a simple way to run tests against the default distribution which
has x-pack basic features enabled while not forcing these tests on all
contributors. You run these tests by doing something like:
```
./gradlew -p qa -Dtests.distribution=zip check
```
or
```
./gradlew -p qa -Dtests.distribution=zip bwcTest
```
x-pack basic *shouldn't* get in the way of any of these tests but
nothing is ever perfect so this we have to disable a few when running
with the zip distribution.
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The following tokenizers were moved: classic, edge_ngram,
letter, lowercase, ngram, path_hierarchy, pattern, thai, uax_url_email and
whitespace.
Left keyword tokenizer factory in server module, because
normalizers directly depend on it.This should be addressed on a
follow up change.

There's no need for an extra `blobExists()` call when writing a blob to the HDFS service. The writeBlob implementation for the HDFS repository already uses the `CreateFlag.CREATE` option on the file creation, which ensures that the blob that's uploaded does not already exist. This saves one network roundtrip.
