When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following
exception:
```json
{
"error" : {
"root_cause" : [
{
"type" : "circuit_breaking_exception",
"reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
"bytes_wanted" : 0,
"bytes_limit" : 0
}
],

}

}
```
This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

This commit cleans up indices in a snapshot repository when all
snapshots containing the index are all deleted. Previously, empty
indices folders would lay around after all snapshots containing
them were deleted.
conform with the requirements of the writeBlob method by
throwing a FileAlreadyExistsException if attempting to write
to a blob that already exists. This change means implementations
of BlobContainer should never overwrite blobs - to overwrite a
blob, it must first be deleted and then can be written again.
Closes#15579
In an effort to reduce the number of tiny packages we have in the
code base this moves all the files that were in subdirectories of
`org.elasticsearch.rest.action.admin.cluster` into
`org.elasticsearch.rest.action.admin.cluster`.
Also fixes line length in these packages.
While I was working on #18703, I discovered a bad behavior when people don't provide AWS key/secret as part as their `elasticsearch.yml` but rely on SysProps or env. variables...
In [`InternalAwsS3Service#getClient(...)`](d4366f8493/plugins/repository-s3/src/main/java/org/elasticsearch/cloud/aws/InternalAwsS3Service.java (L76-L141)), we have:
```java
Tuple<String, String> clientDescriptor = new Tuple<>(endpoint, account);
AmazonS3Client client = clients.get(clientDescriptor);
```
But if people don't provide credentials, `account` is `null`.
Even if it actually could work, I think that we should use the `AWSCredentialsProvider` we create later on and extract from it the `account` (AWS KEY actually) and then use it as the second value of the tuple.
Closes#19557.
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
In #15950#15080#16084 we added the support of TimeOut for Requests with a default client`setTimeoutIntervalInMs`.
So we can remove this useless todo which was added for only one method.
Closes#18617.
Azure and Google cloud blob containers, as the APIs for both return
a 404 in the case of a missing object, which we already handle through
a NoSuchFileFoundException.
Follow up for #18662 and #18690.
* For consistency, we rename method parameters and use `key` and `secret` instead of `account` and `key`.
* We add some tests to check that settings are correctly applied.
* Tests revealed that some checks are bad like for #18662.

Today we are registering repository settings when `S3RepositoryPlugin` starts:
```java
settingsModule.registerSetting(S3Repository.Repository.KEY_SETTING);
settingsModule.registerSetting(S3Repository.Repository.SECRET_SETTING);
settingsModule.registerSetting(S3Repository.Repository.BUCKET_SETTING);
settingsModule.registerSetting(S3Repository.Repository.ENDPOINT_SETTING);
settingsModule.registerSetting(S3Repository.Repository.PROTOCOL_SETTING);
settingsModule.registerSetting(S3Repository.Repository.REGION_SETTING);
settingsModule.registerSetting(S3Repository.Repository.SERVER_SIDE_ENCRYPTION_SETTING);
settingsModule.registerSetting(S3Repository.Repository.BUFFER_SIZE_SETTING);
settingsModule.registerSetting(S3Repository.Repository.MAX_RETRIES_SETTING);
settingsModule.registerSetting(S3Repository.Repository.CHUNK_SIZE_SETTING);
settingsModule.registerSetting(S3Repository.Repository.COMPRESS_SETTING);
settingsModule.registerSetting(S3Repository.Repository.STORAGE_CLASS_SETTING);
settingsModule.registerSetting(S3Repository.Repository.CANNED_ACL_SETTING);
settingsModule.registerSetting(S3Repository.Repository.BASE_PATH_SETTING);
```
We don't need to register those settings as they are repository level settings and not node level settings.
Closes#18945.
creation in the REST tests, as we no longer need it due
to index creation now waiting for active shard copies
before returning (by default, it waits for the primary of
each shard, which is the same as ensuring yellow health).

Also introduced a `Processor.Parameters` class that is holder for several services processors rely on,
the IngestPlugin#getProcessors(...) method has been changed to accept `Processor.Parameters` instead
of each service seperately.
This commit renames the Netty 3 transport module from transport-netty to
transport-netty3. This is to make room for a Netty 4 transport module,
transport-netty4.
Relates #19439
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
This change adds a createComponents() method to Plugin implementations
which they can use to return already constructed componenents/services.
Eventually this should be just services ("components" don't really do
anything), but for now it allows any object so that preconstructed
instances by plugins can still be bound to guice. Over time we should
add basic services as arguments to this method, but for now I have left
it empty so as to not presume what is a necessary service.
