`document_type` is the type to use for parsing the document to percolate, which
is already optional and deprecated. However `percotale` queries also have the
ability to percolate existing documents, identified by an index, an id and a
type. This change makes the latter optional and deprecated.

This fixes a bug where a String to char cast in Painless could be done implicitly.
It is now required that a String to char cast is explicit as documented in the

Prior to this commit (and after 6.5.0), if an ingest node changes
the _index in a pipeline, the original target index would be created.
For daily indexes this could create an extra, empty index per day.
This commit changes the TransportBulkAction to execute the ingest node
pipeline before attempting to create the index. This ensures that the
only index created is the original or one set by the ingest node pipeline.
This was the execution order prior to 6.5.0 (#32786).
The execution order was changed in 6.5 to better support default pipelines.
Specifically the execution order was changed to be able to read the settings
from the index meta data. This commit also includes a change in logic such
that if the target index does not exist when ingest node pipeline runs, it
will now pull the default pipeline (if one exists) from the settings of the
best matched of the index template.

In integration tests where `setBootstrapMasterNodeIndex()` is used in
combination with `autoMinMasterNodes = false` the cluster can start
bootstrapping once the number of nodes set with the
`setBootstrapMasterNodeIndex` have been started but it's not ensured
that all nodes have successfully joined to form the cluster.
This behaviour was introduced with 5db7ed22a0
and in order to ensure that the cluster is properly formed before proceeding
with the integration test, use `ensureStableCluster()` with the
appropriate number of expected nodes.

The existing formatter being used was not on par with the joda formatter
as it was missing the ability to parse a comma as a separator between
seconds and milliseconds.
While a real iso8601 would be much more complex, this might be
sufficient for some more use-cases.
The ingest date formatter now also uses the iso8601 formatter by
default.
Closes#38345
Currently tests still use custom type names. In preparation for the final types
removal this change moves all of them to use the default "_doc" type in tests.
If no timezone was specified in the date processor, then the conversion
would lead to wrong time, as UTC was assumed by default, leading to
incorrectly parsed dates.
This commit does not assume a default timezone and will thus not format
the dates in a wrong way.
We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.
The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).
Given all these issues, it seems that this custom timeout mechanism
gives little benefits while causing a lot of harm. We should rather rely
on connect and socket timeout exposed by the underlying http client
and accept that a request can overall take longer than the configured
timeout, which is the case even with a single retry anyways.
This commit removes the `maxRetryTimeout` setting and all of its usages.
Elasticsearch has long [supported](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-versioning) compare and set (a.k.a optimistic concurrency control) operations using internal document versioning. Sadly that approach is flawed and can sometime do the wrong thing. Here's the relevant excerpt from the resiliency status page:
> When a primary has been partitioned away from the cluster there is a short period of time until it detects this. During that time it will continue indexing writes locally, thereby updating document versions. When it tries to replicate the operation, however, it will discover that it is partitioned away. It won’t acknowledge the write and will wait until the partition is resolved to negotiate with the master on how to proceed. The master will decide to either fail any replicas which failed to index the operations on the primary or tell the primary that it has to step down because a new primary has been chosen in the meantime. Since the old primary has already written documents, clients may already have read from the old primary before it shuts itself down. The version numbers of these reads may not be unique if the new primary has already accepted writes for the same document
We recently [introduced](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/optimistic-concurrency-control.html) a new sequence number based approach that doesn't suffer from this dirty reads problem.
This commit removes support for internal versioning as a concurrency control mechanism in favor of the sequence number approach.
Relates to #1078
`CreateIndexRequest#source(Map<String, Object>, ... )`, which is used when
deserializing index creation requests, accidentally accepts mappings that are
nested twice under the type key (as described in the bug report #38266).
This in turn causes us to be too lenient in parsing typeless mappings. In
particular, we accept the following index creation request, even though it
should not contain the type key `_doc`:
```
PUT index?include_type_name=false
{
"mappings": {
"_doc": {
"properties": { ... }
}
}
}
```
There is a similar issue for both 'put templates' and 'put mappings' requests
as well.
This PR makes the minimal changes to detect and reject these typed mappings in
requests. It does not address #38266 generally, or attempt a larger refactor
around types in these server-side requests, as I think this should be done at a
later time.
With this change we no longer support pluggable discovery implementations. No
known implementations of `DiscoveryPlugin` actually override this method, so in
practice this should have no effect on the wider world. However, we were using
this rather extensively in tests to provide the `test-zen` discovery type. We
no longer need a separate discovery type for tests as we no longer need to
customise its behaviour.

This test has been awaiting a fix that isn't currently relevant because incoming
lambda parameters are read-only. If this ever changes a new set of tests can
be added that are up-to-date.
This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.
Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.
Currently, there are a few tests that use autoMinMasterNodes=false and
hence override addExtraClusterBootstrapSettings, mostly this is 10-30
lines of codes that are copy-pasted from class to class.
This PR introduces `InternalTestCluster.setBootstrapMasterNodeIndex`
which is suitable for all classes and copy-paste could be removed.
Removing code is always a good thing!
When the ingest node user agent parses the device field, it

Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
With #37566 we have introduced the ability to merge multiple search responses into one. That makes it possible to expose a new way of executing cross-cluster search requests, that makes CCS much faster whenever there is network latency between the CCS coordinating node and the remote clusters. The coordinating node can now send a single search request to each remote cluster, which gets reduced by each one of them. from + size results are requested to each cluster, and the reduce phase in each cluster is non final (meaning that buckets are not pruned and pipeline aggs are not executed). The CCS coordinating node performs an additional, final reduction, which produces one search response out of the multiple responses received from the different clusters.
This new execution path will be activated by default for any CCS request unless a scroll is provided or inner hits are requested as part of field collapsing. The search API accepts now a new parameter called ccs_minimize_roundtrips that allows to opt-out of the default behaviour.

The existing implementation was slow due to exceptions being thrown if
an accessor did not have a time zone. This implementation queries for
having a timezone, local time and local date and also checks for an
instant preventing to throw an exception and thus speeding up the conversion.
This removes the existing method and create a new one named
DateFormatters.from(TemporalAccessor accessor) to resemble the naming of
the java time ones.
Before this change an epoch millis parser using the toZonedDateTime
method took approximately 50x longer.

* Add ECS schema for user-agent ingest processor (#37727)
This switches the format of the user agent processor to use the schema from [ECS](https://github.com/elastic/ecs).

"os_major" : "10",
"name" : "Chrome",
"os_name" : "Mac OS X",
"device" : "Other"
}
```
The structure is now like this:
```
{
"name" : "Chrome",
"original" : "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36",
"os" : {

"full" : "Mac OS X 10.14.1"
},
"device" : "Other",
"version" : "70.0.3538.102"
}
```
This is now the default for 7.0. The deprecated `ecs` setting in 6.x is not
supported.
Resolves#37329
* Remove `ecs` setting from docs
This drops the option for tests to disable strict deprecation mode in
the low level rest client in favor of configuring expected warnings on
any calls that should expect warnings. This behavior is
paranoid-by-default which is generally the right way to handle
deprecations and tests in general.
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.
The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.
The delete and update by query APIs both offer protection against overriding concurrent user changes to the documents they touch. They currently are using internal versioning. This PR changes that to rely on sequences numbers and primary terms.

The ingest date processor is currently only able to parse joda formats.
However it is not using the existing elasticsearch classes but access
joda directly. This means that our existing BWC layer does not notify
the user about deprecated formats. This commit switches to use the
exising Elasticsearch Joda methods to acquire a date format, that
includes the BWC check and the ability to parse java 8 dates.
The date parsing in ingest has also another extra feature, that the
fallback year, when a date format without a year is used, is the current
year, and not 1970 like usual. This is currently not properly supported
in the DateFormatter class. As this is the only case for this feature
and java time can take care of this using the toZonedDateTime() method,
a workaround just for the joda time parser has been created, that can be
removed soon again from 7.0.
Ranaming as follows:
feature -> rank_feature
feature_vector -> rank_features
feature query -> rank_feature query
Ranaming is done to distinguish from other vector types.

Users may require the sequence number and primary terms to perform optimistic concurrency control operations. Currently, you can get the sequence number via the `docvalues_fields` API but the primary term is not accessible because it is maintained by the `SeqNoFieldMapper` and the infrastructure can't find it.
This commit adds a dedicated sub fetch phase to return both numbers that is connected to a new `seq_no_primary_term` parameter.
This adds a set of helper classes to determine if an agg "has a value".
This is needed because InternalAggs represent "empty" in different
manners according to convention. Some use `NaN`, `+/- Inf`, `0.0`, etc.
A user can pass the Internal agg type to one of these helper methods
and it will report if the agg contains a value or not, which allows the
user to differentiate "empty" from a real `NaN`.
These helpers are best-effort in some cases. For example, several
pipeline aggs share a single return class but use different conventions
to mark "empty", so the helper uses the loosest definition that applies
to all the aggs that use the class.
Sums in particular are unreliable. The InternalSum simply returns 0.0
if the agg is empty (which is correct, no values == sum of zero). But this
also means the helper cannot differentiate from "empty" and `+1 + -1`.
This commit introduces a NetworkMessage class. This class has two
subclasses - InboundMessage and OutboundMessage. These messages can
be serialized and deserialized independent of the transport. This allows
more granular testing. Additionally, the serialization mechanism is now
a simple Supplier. This builds the framework to eventually move the
serialization of transport messages to the network thread. This is the
one serialization component that is not currently performed on the
network thread (transport deserialization and http serialization and
deserialization are all on the network thread).
This adds deprecation to _type in the script contexts for ingest and update.
This adds a DeprecationMap that wraps the ctx Map containing _type for these
specific contexts.

for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.

Prior to this change, any field in an ingest node processor that supports
script templates would be compiled as mustache template regardless if they

harmless. However, each compilation counts against the script compilation

In Lucene 8 searches can skip non-competitive hits if the total hit count is not requested.
It is also possible to track the number of hits up to a certain threshold. This is a trade off to speed up searches while still being able to know a lower bound of the total hit count. This change adds the ability to set this threshold directly in the track_total_hits search option. A boolean value (true, false) indicates whether the total hit count should be tracked in the response. When set as an integer this option allows to compute a lower bound of the total hits while preserving the ability to skip non-competitive hits when enough matches have been collected.

Reindex from remote was using a custom regex to dermine what URIs were

This commit modifies ESSingleNodeTestCase and ESIntegTestCase and
several concrete test classes to use node names when bootstrapping the
cluster.
Today ClusterBootstrapService.INITIAL_MASTER_NODE_COUNT_SETTING
setting is used to bootstrap clusters in tests. Instead, we want to use
ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING and get rid of
the former setting eventually.
There were two main problems when refactoring InternalTestCluster:
1. Nodes are created one-by-one in buildNode method. And node.name
is created in this method as well. It's not suitable for bootstrapping,
because we need to have the names of all master eligible nodes in
advance, before creating the node with bootstrapping configuration set.
We address this issue by separating buildNode into two methods:
getNodeSettings and buildNode. We first iterate over all nodes to
get nodes settings, then change the setting for the bootstrapping node
and then proceed with building the node.
2. If autoManageMinMasterNodes = false, there is no way for the test to
set the list of bootstrapping nodes because node names are not known in
advance. This problem is solved by adding updateNodesSettings method
to NodeConfigurationSource and ESIntegTestCase (which could be
overridden by concrete integration test class). Once we have the list
of settings for all nodes, the integration test class is allowed to
update it. In our case, we update the
ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING setting.

This commit adds an adjust_offsets parameter to the word_delimiter_graph token filter, defaulting
to true. Most of the time you'd want sub-tokens emitted by this filter to have offsets that are
adjusted to their real position in the token stream; however, some token filters can change the
length or starting position of a token (eg trim) without changing their offset attributes, and this
can lead to word_delimiter_graph emitting illegal offsets. Setting adjust_offsets to false in these
cases will allow indexing again.
