This commit renames the bulk thread pool to the write thread pool. This
is to better reflect the fact that the underlying thread pool is used to
execute any document write request (single-document index/delete/update
requests, and bulk requests).
With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.
We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.
Added an api that allows to execute an arbitrary script and a result to be returned.
```
POST /_scripts/painless/_execute
{
"script": {
"source": "params.var1 / params.var2",
"params": {
"var1": 1,
"var2": 1
}
}
}
```

The internal test cluster can sometimes have 0 nodes. In this situation,
the http.enabled flag will never be read, and thus no deprecation
warning will be emitted. This commit guards the deprecation warning
check in this case.
The index thread pool is gone, so the index thread pool stats do not any
longer need to be whitelisted in the monitoring stats.

This allows the grammar to determine when and what delimiters statements will use by
splitting up the statements into regular statements and delimited statements, those that do
not require a delimiter versus those that do. This allows consumers of the statements to
determine what delimiters the statements will use so that in certain cases semicolons are
not necessary like when there's a closing right bracket.
This change removes the need for semicolon insertion in the lexer, simplifying the existing
lexer quite a bit. It also ensures that there isn't a need to track semicolons being inserted
into places that aren't necessary such as array initializers.
* Add a CHANGELOG file for 7.x release notes.
* update file to include 6.x
* remove confusing comment and small edit to section title
* moving CHANGELOG file under docs directory, as it pertains to release notes.
Now that single-document indexing requests are executed on the bulk
thread pool the index thread pool is no longer needed. This commit
removes this thread pool from Elasticsearch.
The test was using a parameter on GET /_cluster/health that older nodes
do not understand. Yet, we do no even need to make this call here, we
can use ensure green for the index.
Binary doc values are retrieved during the DocValueFetchSubPhase through an instance of ScriptDocValues.
Since 6.0 ScriptDocValues instances are not allowed to reuse the object that they return (https://github.com/elastic/elasticsearch/issues/26775) but BinaryScriptDocValues doesn't follow this restriction and reuses instances of BytesRefBuilder among different documents.
This results in `field` values assigned to the wrong document in the response.
This commit fixes this issue by recreating the BytesRef for each value that needs to be returned.
Fixes#29565
When calculating the current load on each ML node during the
node allocation process we should be ignoring failed jobs.
This is because failed jobs do not have a corresponding native
process, so do not consume memory or CPU resources.

These tests test actually watcher 6.x features and are not needed in the
master branch anymore, as there is no way that watcher is running on the
master node only in Elaticsearch 7.x.

Rolling up indices that contain multiple schemas requires extra
considerations for the user, and in some cases, some limitations. This
commit tries to enumerate the issues so the user is aware.

When comparing doubles, fixed epsilons can fail because the absolute
difference in values may be quite large, even though the relative
difference is tiny (e.g. with two very large numbers).
Instead, we can scale epsilon by the absolute value of the expected
value. This means we are looking for a diff that is epsilon-percent
away from the value, rather than just epsilon.
This is basically checking the relative error using junit's assertEqual.
Closes#29456, unmutes the test
As part of adding support for new API to the high-level REST client,
we added support for the `flat_settings` parameter to some of our
request classes. We added documentation that such flag is only ever
read by the high-level REST client, but the truth is that it doesn't
do anything given that settings are always parsed back into a `Settings`
object, no matter whether they are returned in a flat format or not.
It was a mistake to add support for this flag in the context of the
high-level REST client, hence this commit removes it.
Instead of allowing the `_xpack/monitoring/_bulk` to remain on the same
thread, it should execute on a separate thread to avoid blocking the
http worker thread whenever the exporters get stuck waiting on the
monitoring cluster.

This refactors MapperService so that it wraps a single `DocumentMapper` rather
than a `Map<String, DocumentMapper>`. We will need follow-ups since I haven't
fixed most APIs that still expose collections of types of mappers, but this is
a start...
Currently this fails because the Eclipse configuration splits the main and test
folders into separate projects to avoid circular dependencies.

Today the translog of an engine is exposed and can be accessed directly.
While this exposure offers much flexibility, it also causes these troubles:
- Inconsistent behavior between translog method and engine method.
For example, rolling a translog generation via an engine also trims
unreferenced files, but translog's method does not.
- An engine does not get notified when critical errors happen in translog
as the access is direct.
This change isolates translog of an engine and enforces all accesses to
translog via the engine.
Updates documentation describing the parameters for optionally signing the
SAML medatata document that the saml-metadata command creates.

The index thread pool is no longer needed as its primary use-case for
single-document indexing requests has been relieved now that
single-document indexing requests are converted to bulk indexing
requests (with a single document payload).
We want to remove the index thread pool as it is no longer needed since
single-document indexing requests are executed as bulk requests
now. Analyze requests are also executed on the index thread pool though
and they need a thread pool to execute on. The bulk thread does not seem
like the right thread pool, let us keep that thread pool conceptually
for bulk requests and free for bulk requests. None of the existing
thread pools make sense for analyze requests either. The generic thread
pool would be a terrible choice since it has an unbounded queue and that
is a bad idea for user-facing APIs. This commit introduces a small by
default (size=1, queue_size=16) thread pool for analyze requests.
This commit add the `include_type_name` option to the `index`, `update`,
`delete`, `get`, `bulk` and `search` APIs. When set to `false`, the response
will omit the `_type` in the response. This option doesn't work if the endpoint
contains a type. For instance, the following call would succeed:
```
GET index/_doc/1?include_type_name=false
```
But the following one would fail:
```
GET index/some_type/1?include_type_name=false
```

Previously "certutil" would generate a zip file if there were multiple
certificates.
However, this means that if the user specified "-multiple" or "-in"
then the output format will vary based on whether they entered
multiple instance names (-multiple) or whether the input file
contained multiple instance records (-in).
It is better if the output format is predictable based on the command
line options, so this change forces zip output whenever any of the
following command line options are supplied:
-pem
-keep-ca-key
-multiple
-in

The handling of the "--pass" option has complex rules due to the
different requirements of different output formats, and the way
joptsimple handles specs with optional arguments.
A standard unix shell will parse
certutil --pass=""
as being identical to
certutil --pass=
and joptsimple treats that as being "no argument", i.e. the same as
certutil --pass
The only way to pass a blank password is
certutil --pass ""
(though this is shell dependent)

OpenSAML requires that the context classloader be set to the
classloader that contains the opensaml jar files in order to
initialise itself. However, sometimesrthis seems to cause the
classloading for slf4j/log4j to take place while that context
classloader is set, which fails.
This change forces slf4j/log4j to be initialised prior to setting
the context classloader.

This test is failing because of an addition of a call to GET
/_cluster/health with the parameter wait_for_no_initializing_shards set
to true. As older versions of Elasticsearch do not understand this
parameter, this request fails and the test fails. This commit marks this
test as awaiting a fix.
This commit fixes plugin warning confirmation to include native
controller confirmation when no security policy exists. The case was
already covered for meta plugins, but not for normal plugins. Tests are
also added for all cases.
