After #13834 many tests that used Groovy scripts (for good or bad reason) in their tests have been moved in the lang-groovy module and the issue #13837 has been created to track these messy tests in order to clean them up.
This commit moves more tests back in core, removes the dependency on Groovy, changes the scripts in order to use the mocked script engine, and change the tests to integration tests.
This commit moves back some messy tests that have been placed in lang-groovy module in https://github.com/elastic/elasticsearch/pull/13834. It removes the dependency on Groovy plugin as well as change back the tests to integration tests (IT suffix).
It also changes the current MockScriptEngine and MockScriptPlugin to make it easier to use.
This adds a new proxy for RestHandlers and RestControllers so that requests made
to deprecated REST APIs can be automatically logged in the ES logs via the
DeprecationLogger as well as via a "Warning" header (RFC-7234) for all responses.
Calling indicesService.deleteIndex() can trip an assertion if there is an ongoing cluster state applied in
IndicesClusterStateService. This means that the index is possibly deleted after the failMissingShards
check and before we try creating new and updated shards, tripping an assertion that non-existing shards must
have shard state initializing (started in this case).
This change adds the type of the field in the fieldstats response.
It can be one of the following:
* "integer" for byte, short, integer and long
* "float" for float, half-float and double
* "date" for date
* "ip" for ip
* "text" for string, keyword and text.
Closes#17750
This adds a remote option to reindex that looks like
```
curl -POST 'localhost:9200/_reindex?pretty' -d'{
"source": {
"remote": {
"host": "http://otherhost:9200"
},
"index": "target",
"query": {
"match": {
"foo": "bar"
}
}
},
"dest": {
"index": "target"
}
}'
```
This reindex has all of the features of local reindex:
* Using queries to filter what is copied
* Retry on rejection
* Throttle/rethottle
The big advantage of this version is that it goes over the HTTP API
which can be made backwards compatible.
Some things are different:
The query field is sent directly to the other node rather than parsed
on the coordinating node. This should allow it to support constructs
that are invalid on the coordinating node but are valid on the target
node. Mostly, that means old syntax.
This commit renames writeThrowable to writeException. The situation here
stems from the fact that the StreamOutput method for serializing
Exceptions needs to accept Throwables too as Throwables can be the cause
of serialized Exceptions. Yet, we do not serialize Throwables in the
Error sub-hierarchy in a way that they can be deserialized into their
initial type. This leads to an asymmetry in the StreamOutput method for
serializing Exceptions and the StreamInput method for writing
Excpetions. Namely, the former will accept Throwables but the latter
will only return Exceptions. A goal with the stream methods has always
been symmetry in the method names so that serialization/deserialization
routines appear symmetrical in code. It is this asymmetry on the
input/output types for Exceptions on StreamOutput/StreamInput that
clashes with the desired symmetry of naming. Despite this, we should
favor symmetry in the naming of the methods. This commit renames
StreamOutput#writeThrowable to StreamOutput#writeException which leaves
us with Exception StreamInput#readException and void
StreamOutput#writeException(Throwable).
This commit modifies the initial value of the transport client
round-robin index to a random value so that initial requests are more
likely to not all hit the same node.

This change activates the doc_values on the _size field for indices created after 5.0.0-alpha4.
It also adds a note in the breaking changes that explain the situation and how to get around it.
Closes#18334
Due to some optimization on the netty layer we had quite some code / cruft
added to the TcpTransport to allow for those optimizations. After cleaning
up BytesReference we can now move this optimization into TcpTransport and
have a simple send method on the implementation layer instead. This commit
adds a CompositeBytesReference that also allows message headers to be written
separately which simplify the header code as well since no skips are needed
anymore.
The top-level class Throwable represents all errors and exceptions in
Java. This hierarchy is divided into Error and Exception, the former
being serious problems that applications should not try to catch and the
latter representing exceptional conditions that an application might
want to catch and handle. This commit renames
org.elasticsearch.cli.UserError to org.elasticsearch.UserException to
make its name consistent with where it falls in this hierarchy.
