RankEvalRequest should implement IndicesRequest (#29188)
Change RankEvalRequest to implement IndicesRequest, so it gets treated
in a similar fashion to regular search requests e.g. by security.

Remove BytesArray and BytesReference usage from XContentFactory (#29151)
* Remove BytesArray and BytesReference usage from XContentFactory

This removes the usage of `BytesArray` and `BytesReference` from
`XContentFactory`. Instead, a regular `byte[]` should be passed. To assist with
this a helper has been added to `XContentHelper` that will preserve the offset
and length from the underlying BytesReference.

This is part of ongoing work to separate the XContent parts from ES so they can
be factored into their own jar.

Move indices field from RankEvalSpec to RankEvalRequest (#28341)
Currently we store the indices specified in the request URL together with all
the other ranking evaluation specification in RankEvalSpec. This is not ideal
since e.g. the indices are not rendered to xContent and so cannot be parsed
back. Instead we should keep them in RankEvalRequest.

Fix EsAbortPolicy to conform to API (#29075)
The rejected execution handler API says that rejectedExecution(Runnable,
ThreadPoolExecutor) throws a RejectedExecutionException if the task must
be rejected due to capacity on the executor. We do throw something that
smells like a RejectedExecutionException (it is named
EsRejectedExecutionException) yet we violate the API because
EsRejectedExecutionException is not a RejectedExecutionException. This
has caused problems before where we try to catch RejectedExecution when
invoking rejectedExecution but this causes EsRejectedExecutionException
to go uncaught. This commit addresses this by modifying
EsRejectedExecutionException to extend
RejectedExecutionException.

Added minimal docs for reindex api in java-api docs
Additionally:
* Included the existing update by query java api docs in java-api docs.
  (for some reason it was never included, it needed some tweaking and
  then it was good to go)
* moved delete-by-query / update-by-query code samples to java file so
  that we can verify that these samples at least compile.

Decouple XContentBuilder from BytesReference (#28972)
* Decouple XContentBuilder from BytesReference

This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.

While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).

Copy Lucene IOUtils (#29012)
As we have factored Elasticsearch into smaller libraries, we have ended
up in a situation that some of the dependencies of Elasticsearch are not
available to code that depends on these smaller libraries but not server
Elasticsearch. This is a good thing, this was one of the goals of
separating Elasticsearch into smaller libraries, to shed some of the
dependencies from other components of the system. However, this now
means that simple utility methods from Lucene that we rely on are no
longer available everywhere. This commit copies IOUtils (with some small
formatting changes for our codebase) into the fold so that other
components of the system can rely on these methods where they no longer
depend on Lucene.

Martijn van Groningen beb22d89c8 percolator: Take `matchAllDocs` and `verified` of the sub result into account when analyzing a function_score query.
Before the `matchAllDocs` was ignored and this could lead to percolator queries not matching when
the inner query was a match_all query and min_score was specified.

Before when `verified` was not taken into account if the function_score query wrapped an unverified query this could
lead to matching percolator queries that shouldn't match at all.

Continue registering pipelines after one pipeline parse failure. (#28752)
Ingest has been failing to apply existing pipelines from cluster-state
into the in-memory representation that are no longer valid. One example of
this is a pipeline with a script processor. If a cluster starts up with scripting
disabled, these pipelines will not be loaded. Even though GETing a pipeline worked,
indexing operations claimed that this pipeline did not exist. This is because one
gets information from cluster-state and the other is from an in-memory data-structure.

Now, two things happen
1. suppress the exceptions until after other successful pipelines are loaded
2. replace failed pipelines with a placeholder pipeline

If the pipeline execution service encounters the stubbed pipeline, it is known that
something went wrong at the time of pipeline creation and an exception was thrown to
the user at some point at start-up.

closes #28269.

Decouple XContentType from StreamInput/Output (#28927)

Pass InputStream when creating XContent parser (#28754)

Rather than passing the raw `BytesReference` in when creating the xcontent
parser, this passes the StreamInput (which is an InputStream), this allows us to

external commons classes.

Martijn van Groningen 766b9d600e
Fixed a bug that prevents pipelines to load that use stored scripts after a restart.
The bug was caused because the ScriptService had no reference to a ClusterState instance,
because it received the ClusterState after the PipelineStore. This only is the case
after a restart.

A bad side effect is that during a restart, any pipeline to be loaded after the pipeline that uses a stored script,
was never loaded, which caused many pipeline to be missing in bulk / index request api calls.

Scripts: Fix security for deprecation warning (#28485)
If you call `getDates()` on a long or date type field add a deprecation
warning to the response and log something to the deprecation logger.
This *mostly* worked just fine but if the deprecation logger happens to
roll then the roll will be performed with the script's permissions
rather than the permissions of the server. And scripts don't have
permissions to, say, open files. So the rolling failed. This fixes that
by wrapping the call the deprecation logger in `doPriviledged`.

This is a strange `doPrivileged` call because it doens't check
Elasticsearch's `SpecialPermission`. `SpecialPermission` is a permission
that no-script code has and that scripts never have. Usually all
`doPrivileged` calls check `SpecialPermission` to make sure that they
are not accidentally acting on behalf of a script. But in this case we
are *intentionally* acting on behalf of a script.

XContent: Factor deprecation handling into callback (#28449)
Factors the way in which XContent parsing handles deprecated fields
into a callback that is set at parser construction time. The goals here
are:
1. Remove Log4J as a dependency of XContent so that XContent can be used
by clients without forcing log4j and our particular deprecation handling
scheme.
2. Simplify handling of deprecated fields in tests. Now tests can listen
directly for the deprecation callback rather than digging through a
ThreadLocal.

More accurately, this change begins this work. It deprecates a number of
methods, pointing folks to the new versions of those methods that take
`DeprecationHandler`. The plan is to slowly drop these deprecated
methods. Once they are entirely removed we can remove Log4j as
dependency of XContent.

This change adds yet more logging so future failure of this kind will be

all child tasks to be running or completed before rethrottling. This
*might* avoid the failure because once a child task is properly started

Nik Everett eded5bc4f3 Reindex: Wait for deletion in test
The test failure tracked by #28053 occurs because we fail to get the
failure response from the reindex on the first try and on our second try
the delete index API call that was supposed to trigger the failure
actually deletes the index during document creation. This causes the
test to fail catastrophically.

This PR attempts to wait for the failure to finish before the test moves
on to the second attempt. The failure doesn't reproduce locally for me
so I can't be sure that this helps at all with the failure, but it
certainly feels like it should help some. Here is hoping this prevents
similar failures in the future.

response *looks* canceled but none of the children look canceled. This
is super strange because for the main request to look canceled for any
length of time one of the children has to be canceled.

to debug this the next time it fails.

enclosing `rank_eval` object. This is redundant since it is clear from the API
call and it doesn't provide any other useful information. This change removes
this.

`MockTcpTransport` to connect asynchronously (#28203)
The method `initiateChannel` on `TcpTransport` is explicit in that
channels can be connect asynchronously. All production implementations
do connect asynchronously. Only the blocking `MockTcpTransport`
connects in a synchronous manner. This avoids testing some of the
blocking code in `TcpTransport` that waits on connections to complete.
Additionally, it requires a more extensive method signature than
required for other transports.

This commit modifies the `MockTcpTransport` to make these connections
asynchronously on a different thread. Additionally, it simplifies that
`initiateChannel` method signature.

Add ability to associate an ID with tasks (#27764)
Adds support for capturing the X-Opaque-Id header from a REST request and storing it's value in the tasks that this request started. It works for all user-initiated tasks (not only search).

Automatically prepare indices for splitting (#27451)
Today we require users to prepare their indices for split operations.
Yet, we can do this automatically when an index is created which would
make the split feature a much more appealing option since it doesn't have
any 3rd party prerequisites anymore.

This change automatically sets the number of routinng shards such that
an index is guaranteed to be able to split once into twice as many shards.
The number of routing shards is scaled towards the default shard limit per index
such that indices with a smaller amount of shards can be split more often than
larger ones. For instance an index with 1 or 2 shards can be split 10x
(until it approaches 1024 shards) while an index created with 128 shards can only
be split 3x by a factor of 2. Please note this is just a default value and users
can still prepare their indices with `index.number_of_routing_shards` for custom
splitting.

NOTE: this change has an impact on the document distribution since we are changing
the hash space. Documents are still uniformly distributed across all shards but since
we are artificually changing the number of buckets in the consistent hashign space
document might be hashed into different shards compared to previous versions.

This is a 7.0 only change.

Use the primary_term field to identify parent documents (#27469)
This change stops indexing the `_primary_term` field for nested documents
to allow fast retrieval of parent documents. Today we create a docvalues
field for children to ensure we have a dense datastructure on disk. Yet,
since we only use the primary term to tie-break on when we see the same
seqID on indexing having a dense datastructure is less important. We can
use this now to improve the nested docs performance and it's memory footprint.

Cross Cluster Search: make remote clusters optional (#27182)
Today Cross Cluster Search requires at least one node in each remote cluster to be up once the cross cluster search is run. Otherwise the whole search request fails despite some of the data (either local and/or remote) is available. This happens when performing the _search/shards calls to find out which remote shards the query has to be executed on. This scenario is different from shard failures that may happen later on when the query is actually executed, in case e.g. remote shards are missing, which is not going to fail the whole request but rather yield partial results, and the _shards section in the response will indicate that.

This commit introduces a boolean setting per cluster called search.remote.$cluster_alias.skip_if_disconnected, set to false by default, which allows to skip certain clusters if they are down when trying to reach them through a cross cluster search requests. By default all clusters are mandatory.

Scroll requests support such setting too when they are first initiated (first search request with scroll parameter), but subsequent scroll rounds (_search/scroll endpoint) will fail if some of the remote clusters went down meanwhile.

The search API response contains now a new _clusters section, similar to the _shards section, that gets returned whenever one or more clusters were disconnected and got skipped:

"_clusters" : {
    "total" : 3,
    "successful" : 2,
    "skipped" : 1
}
Such section won't be part of the response if no clusters have been skipped.

The per cluster skip_unavailable setting value has also been added to the output of the remote/info API.

Fix issue where pages aren't released (#27459)
This is related to #27422. Right now when we send a write to the netty
transport, we attach a listener to the future. When you submit a write
on the netty event loop and the event loop is shutdown, the onFailure
method is called. Unfortunately, netty then tries to notify the listener
which cannot be done without dispatching to the event loop. In this
case, the dispatch fails and netty logs and error and does not tell us.

This commit checks that netty is still not shutdown after sending a
message. If netty is shutdown, we complete the listener.

Transition transport apis to use void listeners (#27440)
Currently we use ActionListener<TcpChannel> for connect, close, and send
message listeners in TcpTransport. However, all of the listeners have to
capture a reference to a channel in the case of the exception api being
called. This commit changes these listeners to be type <Void> as passing
the channel to onResponse is not necessary. Additionally, this change
makes it easier to integrate with low level transports (which use
different implementations of TcpChannel).

This commit is a follow up to the work completed in #27132. Essentially
it transitions two more methods (sendMessage and getLocalAddress) from

TcpTransport to be aware of the specific type of channel a transport
returns. So that class is no longer parameterized by channel type.

Add composite aggregator (#26800)
* This change adds a module called `aggs-composite` that defines a new aggregation named `composite`.
The `composite` aggregation is a multi-buckets aggregation that creates composite buckets made of multiple sources.
The sources for each bucket can be defined as:
  * A `terms` source, values are extracted from a field or a script.
  * A `date_histogram` source, values are extracted from a date field and rounded to the provided interval.
This aggregation can be used to retrieve all buckets of a deeply nested aggregation by flattening the nested aggregation in composite buckets.
A composite buckets is composed of one value per source and is built for each document as the combinations of values in the provided sources.
For instance the following aggregation:

````
"test_agg": {
  "terms": {
    "field": "field1"
  },
  "aggs": {
    "nested_test_agg":
      "terms": {
        "field": "field2"
      }
  }
}
````
... which retrieves the top N terms for `field1` and for each top term in `field1` the top N terms for `field2`, can be replaced by a `composite` aggregation in order to retrieve **all** the combinations of `field1`, `field2` in the matching documents:

````
"composite_agg": {
  "composite": {
    "sources": [
      {
	"field1": {
          "terms": {
              "field": "field1"
            }
        }
      },
      {
	"field2": {
          "terms": {
            "field": "field2"
          }
        }
      },
    }
  }
````

The response of the aggregation looks like this:

````
"aggregations": {
  "composite_agg": {
    "buckets": [
      {
        "key": {
          "field1": "alabama",
          "field2": "almanach"
        },
        "doc_count": 100
      },
      {
        "key": {
          "field1": "alabama",
          "field2": "calendar"
        },
        "doc_count": 1
      },
      {
        "key": {
          "field1": "arizona",
          "field2": "calendar"
        },
        "doc_count": 1
      }
    ]
  }
}
````

By default this aggregation returns 10 buckets sorted in ascending order of the composite key.
Pagination can be achieved by providing `after` values, the values of the composite key to aggregate after.
For instance the following aggregation will aggregate all composite keys that sorts after `arizona, calendar`:

````
"composite_agg": {
  "composite": {
    "after": {"field1": "alabama", "field2": "calendar"},
    "size": 100,
    "sources": [
      {
	"field1": {
          "terms": {
            "field": "field1"
          }
        }
      },
      {
	"field2": {
          "terms": {
            "field": "field2"
          }
	}
      }
    }
  }
````

This aggregation is optimized for indices that set an index sorting that match the composite source definition.
For instance the aggregation above could run faster on indices that defines an index sorting like this:

````
"settings": {
  "index.sort.field": ["field1", "field2"]
}
````

In this case the `composite` aggregation can early terminate on each segment.
This aggregation also accepts multi-valued field but disables early termination for these fields even if index sorting matches the sources definition.
This is mandatory because index sorting picks only one value per document to perform the sort.

Add TcpChannel to unify Transport implementations (#27132)
Right now our different transport implementations must duplicate
functionality in order to stay compliant with the requirements of
TcpTransport. They must all implement common logic to open channels,
close channels, keep track of channels for eventual shutdown, etc.

Additionally, there is a weird and complicated relationship between
Transport and TransportService. We eventually want to start merging
some of the functionality between these classes.

This commit starts moving towards a world where TransportService retains
all the application logic and channel state. Transport implementations
in this world will only be tasked with returning a channel when one is
requested, calling transport service when a channel is accepted from
a server, and starting / stopping itself.

Specifically this commit changes how channels are opened and closed. All
Transport implementations now return a channel type that must comply with
the new TcpChannel interface. This interface has the methods necessary
for TcpTransport to completely manage the lifecycle of a channel. This
includes setting the channel up, waiting for connection, adding close
listeners, and eventually closing.

percolator: fixed issue where in indices created before 6.1 if minimum should match has been specified on a disjunction,
the query would be marked as verified candidate match. This is wrong as it can only marked as verified candidate match
on indices created on or after 6.1, due to the use of the CoveringQuery.

Martijn van Groningen b4048b4e7f
Use CoveringQuery to select percolate candidate matches and
extract all clauses from a conjunction query.

When clauses from a conjunction are extracted the number of clauses is
also stored in an internal doc values field (minimum_should_match field).
This field is used by the CoveringQuery and allows the percolator to
reduce the number of false positives when selecting candidate matches and
in certain cases be absolutely sure that a conjunction candidate match
will match and then skip MemoryIndex validation. This can greatly improve
performance.

Before this change only a single clause was extracted from a conjunction
query. The percolator tried to extract the clauses that was rarest in order
(based on term length) to attempt less candidate queries to be selected
in the first place. However this still method there is still a very high
chance that candidate query matches are false positives.

This change also removes the influencing query extraction added via #26081
as this is no longer needed because now all conjunction clauses are extracted.

Enhances exists queries to reduce need for `_field_names` (#26930)
* Enhances exists queries to reduce need for `_field_names`

Before this change we wrote the name all the fields in a document to a `_field_names` field and then implemented exists queries as a term query on this field. The problem with this approach is that it bloats the index and also affects indexing performance.

This change adds a new method `existsQuery()` to `MappedFieldType` which is implemented by each sub-class. For most field types if doc values are available a `DocValuesFieldExistsQuery` is used, falling back to using `_field_names` if doc values are disabled. Note that only fields where no doc values are available are written to `_field_names`.

Closes #26770

Jason Tedor 9aae2f593a Avoid stack overflow on search phases
When a search is executing locally over many shards, we can stack
overflow during query phase execution. This happens due to callbacks
that occur after a phase completes for a shard and we move to the same
phase on another shard. If all the shards for the query are local to the
local node then we will never go async and these callbacks will end up
as recursive calls. With sufficiently many shards, this will end up as a
stack overflow. This commit addresses this by truncating the stack by
forking to another thread on the executor for the phase.

Tim Brooks a7fa5d3335 Remove dangerous `ByteBufStreamInput` methods (#27076)
This commit removes the `ByteBufStreamInput` `readBytesReference` and
`readBytesRef` methods. These methods are zero-copy which means that
they retain a reference to the underlying netty buffer. The problem is
that our `TcpTransport` is not designed to handle zero-copy. The netty
implementation sets the read index past the current message once it has
been deserialized, handled, and mostly likely dispatched to another
thread. This means that netty is free to release this buffer. So it is
unsafe to retain a reference to it without calling `retain`. And we
cannot call `retain` because we are not currently designed to handle
reference counting past the transport level.

This should not currently impact us as we wrap the `ByteBufStreamInput`
in `NamedWriteableAwareStreamInput` in the `TcpTransport`. This stream
essentially delegates to the underling stream. However, in the case of
`readBytesReference` and `readBytesRef` it leaves thw implementations
to the standard `StreamInput` methods. These methods call the read byte
array method which delegates to `ByteBufStreamInput`. The read byte
array method on `ByteBufStreamInput` copies so it is safe. The only
impact of this commit should be removing methods that could be dangerous
if they were eventually called due to some refactoring.

Jason Tedor 4c06b8f1d2 Check for closed connection while opening
While opening a connection to a node, a channel can subsequently
close. If this happens, a future callback whose purpose is to close all
other channels and disconnect from the node will fire. However, this
future will not be ready to close all the channels because the
connection will not be exposed to the future callback yet. Since this
callback is run once, we will never try to disconnect from this node
again and we will be left with a closed channel. This commit adds a
check that all channels are open before exposing the channel and throws
a general connection exception. In this case, the usual connection retry
logic will take over.

Daniel Mitterdorfer e22844bd2a Allow only a fixed-size receive predictor (#26165)
With this commit we simplify our network layer by only allowing to define a

means that the following (previously undocumented) settings are removed:

* http.netty.receive_predictor_min
* http.netty.receive_predictor_max

Using an adaptive sizing policy in the receive predictor is a very low-level
optimization. The implications on allocation behavior are extremely hard to grasp
(see our previous work in #23185) and adaptive sizing does not provide a lot of
benefits (see benchmarks in #26165 for more details).

Simon Willnauer 00dfdf50cf Represent lists as actual lists inside Settings (#26878)
Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.

With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting.  Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.

Jack Conradson c3746b268c Separate Painless Whitelist Loading from the Painless Definition (#26540)
Adds several small whitelist data structures and a new Whitelist class to separate the idea of loading a whitelist from the actual Painless Definition class. This is the first step of many in allowing users to define custom whitelists per context. Also supports the idea of loading multiple whitelists from different sources for a single context.

Simon Willnauer 9f97f9072a Allow `InputStreamStreamInput` array size validation where applicable (#26692)
Today we can't validate the array length in `InputStreamStreamInput` since
we can't rely on `InputStream.available` yet in some situations we know
the size of the stream and can apply additional validation.
