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.
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 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.
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.
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
```

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.
With the move long ago to execute all single-document indexing requests
as bulk indexing request, the method
PipelineExecutionService#executeIndexRequest is unused and will never be
used in production code. This commit removes this method and cuts over
all tests to use PipelineExecutionService#executeBulkRequest.
Fails the build if any subprojects of `:libs` have dependencies in `:libs`
except for `:libs:elasticsearch-core`.
Since we now have three places where we resolve project substitutions
I've added `dependencyToProject` to `project.ext` in all projects. It
resolves both `project` style dependencies and "external" style (like
"org.elasticsearch:elasticsearch-core:${version}") dependencies to
`Project`s using the `projectSubstitutions`. I use this new function all
three places where resovle project substitutions.
Finally this pulls `apply plugin: 'elasticsearch.build'` out of
`libs/*/build.gradle` and into a subprojects clause in
`libs/build.gradle`. I do this entirely so that I can call
`tasks.precommit.dependsOn checkDependencies` without waiting for the
subprojects to be evaluated or worrying about whether or not they have
`precommit` set up in a normal way.
The following is the current behaviour, tested now through a specific
test.
The low-level REST client doesn't add a leading wildcard when not
provided, unless a `pathPrefix` is configured in which case a trailing
slash will be automatically added when concatenating the prefix and the
provided uri.
Also when configuring a pathPrefix, if it doesn't start with a '/' it
will be modified by adding the missing leading '/'.
CRUD: Parsing changes for UpdateRequest (#29293)
Use `ObjectParser` to parse `UpdateRequest` so we reject unknown fields
and drop support for the `_fields` parameter because it was deprecated
in 5.x.
The default percentiles values and the default highlighter per- and
post-tags are currently publicly accessible and can be altered any time.
This change prevents this by restricting field access.
Today when reading an operation from the current generation fails
tragically we attempt to close the translog. However, by invoking close
before releasing the read lock we end up in self-deadlock because
closing tries to acquire the write lock and the read lock can not be
upgraded to a write lock. To avoid this, we move the close invocation
outside of the try-with-resources that acquired the read lock. As an
extra guard against this, we document the problem and add an assertion
that we are not trying to invoke close while holding the read lock.
This commit is a minor cleanup of a code block in NodeInfo.groovy. We
remove an unused variable, make the formatting of the code consistent,
and cast a property that is typed as an Object to a String to avoid an
annoying IDE warning.
Some build tasks require older JDKs. For example, the BWC build tasks
for older versions of Elasticsearch require older JDKs. It is onerous to
require these be configured when merely compiling Elasticsearch, the
requirement that they be strictly set to appropriate values should only
be enforced if these tasks are going to be executed. To address this, we
lazy configure these tasks.
Rather than checking a substring match, now that
VersionProperties#elasticsearch is a strongly-typed instance of Version,
we can use the Version#isSnapshot convenience method. This commit
switches the root build file to do this.
Today we have a nodeVersion property on the NodeInfo class that we use
to carry around information about a standalone node that we will start
during tests. This property is a String which we usually end up parsing
to a Version anyway to do various checks on it. This can end up
happening a lot during configuration so it would be more efficient and
safer to have this already be strongly-typed as a Version and parsed
from a String only once for each instance of NodeInfo. Therefore, this
commit makes NodeInfo#nodeVersion strongly-typed as a Version.
There are some scenarios where the license on a source file is one that
is compatible with our projects yet we do not want to add the license to
the list of approved license headers (to keep the number of files with
that compatible license contained). This commit adds the ability to
exclude a file from the license check.
Today we have JAVA_HOME for the compiler Java home and RUNTIME_JAVA_HOME
for the test Java home. However, when we compile BWC nodes and run them,
neither of these Java homes might be the version that was suitable for
that BWC node (e.g., 5.6 requires JDK 8 to compile and to run). This
commit adds support for the environment variables JAVA\d+_HOME and uses
the appropriate Java home based on the version of the node being
started. We even do this for reindex-from-old which requires JDK 7 for
these very old nodes. Note that these environment variables are not
required if not running BWC tests, and they are strictly required if
running BWC tests.
