Previously when trying to listen on virtual interfaces during
bootstrap the application would stop working - the interface
couldn't be found by the NetworkUtils class.
The NetworkUtils utilize the underlying JDK NetworkInterface
class which, when asked to lookup by name only takes physical
interfaces into account, failing at virtual (or subinterfaces)
ones (returning null).
Note that when interating over all interfaces, both physical and
virtual ones are taken into account.
This changeset asks for all known interfaces, iterates over them
and matches on the given name as part of the loop, allowing it
to catch both physical and virtual interfaces.
As a result, elasticsearch can now also serve on virtual
interfaces.
A test case has been added which at least makes sure that all
iterable interfaces can be found by their respective name. (It's
not easily possible in a unit test to "fake" virtual interfaces).

Fixes CORS handling so that it uses the defaults for http.cors.allow-methods
and http.cors.allow-headers if none are specified in the config.
Closes#19520
We better read the header, but who knows what can happen, maybe headers are filtered out for some reasons and we don't want to run into an NPE, then we fallback to auto-detection.
Throw explicit IllegalStateException in unexpected situations, like where both response and exception are set, or when both are unset. Add unit test for SyncResponseListener.
#19096 introduced a generic TCPTransport base class so we can have multiple TCP based transport implementation. These implementations can vary in how they respond internally to situations where we concurrently send, receive and handle disconnects and can have different exceptions. However, disconnects are important events for the rest of the code base and should be distinguished from other errors (for example, it signals TransportMasterAction that it needs to retry and wait for the a (new) master to come back). Therefore, we should make sure that all the implementations do the proper translation from their internal exceptions into ConnectTransportException which is used externally.
Similarly we should make sure that the transport implementation properly recognize errors that were caused by a disconnect as such and deal with them correctly. This was, for example, the source of a build failure at https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+multijob-intake/1080 , where a concurrency issue cause SocketException to bubble out of MockTcpTransport.
This PR adds a tests which concurrently simulates connects, disconnects, sending and receiving and makes sure the above holds. It also fixes anything (not much!) that was found it.
creation timeout so they process the index creation cluster state update
before the test finishes and attempts to cleanup. Otherwise, the index
creation cluster state update could be processed after the test finishes
and cleans up, thereby leaking an index in the cluster state that could
cause issues for other tests that wouldn't expect the index to exist.
Closes#19530
making the test wait until all urgent requests are completed before
finishing, so that tear down can properly delete the created index
and cleanup. Without this wait, it was possible that the test would
finish and cleanup the deleted indices would happen before the
index creation even processed, causing the test to leave a created
index behind.
In the lack of tests the analyzer.alias feature was pretty much not working
at all on current master. Issues like #19163 showed some serious problems for users
using this feature upgrading to an alpha version.
This change fixes the processing order and allows aliases to be set for
existing analyzers like `default`. This change also ensures that if `default`
is aliased the correct analyzer is used for `default_search` etc.
Closes#19163

* rethrow script compilation exceptions into ingest configuration exceptions
* update readProcessor to rethrow any exception as an ElasticsearchException
Remove `ParseField` constants used for names where there are no deprecated
names and just use the `String` version of the registration method instead.
This is step 2 in cleaning up the plugin interface for extending
search time actions. Aggregations are next.
This is breaking for plugins because those that register a new query should
now implement `SearchPlugin` rather than `onModule(SearchModule)`.
When index creation is not acknowledged (due to a very low request timeout) it is possible that the index is still created.
If a subsequent index-exists request completes before the cluster state of the index creation has been fully applied, it
might miss the newly created index.
* Remove outdated aggregation registration method
* Remove AggregationStreams
* Adds StreamInput#readNamedWriteableList and
StreamOutput#writeNamedWriteableList convenience methods. We strive to
make the reading and writing from the streams terse so they are easier
to scan visually.
* Remove PipelineAggregatorStreams
* Remove stream info from InternalAggreation.Type
* Remove InternalAggregation#type
* Remove Streamable from PipelineAggregator
* Remove Streamable from MultiBucketsAggregation.Bucket
During query refactoring the query string query parameter
'auto_generate_phrase_queries' was accidentally renamed
to 'auto_generated_phrase_queries'.
With this commit we restore the old name.

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.
Currently if a string field is not_analyzed, but a
position_increment_gap is set, it will lookup the default analyzer and
set it, along with the position_increment_gap, before the code which
handles setting the keyword analyzer for not_analyzed fields has a
chance to run. This change adds a parsing check and test for that case.
ThreadPool#schedule can throw a rejected execution exception. Yet, the
rejected execution exception that it throws comes from the EsAbortPolicy
which throws an EsRejectedExecutionException. This exception does not
inherit from RejectedExecutionException so instead we must catch the
former instead of the latter.
A self-rescheduling runnable can hit a rejected execution exception but
this exception goes uncaught. Instead, this exception should be caught
and passed to the onRejected handler. Not catching handling this
rejected execution exception can lead to test failures. Namely, a race
condition can arise between the shutting down of the thread pool and
cancelling of the rescheduling of the task. If another reschedule fires
right as the thread pool is being terminated, the rescheduled task will
be rejected leading to an uncaught exception which will cause a test
failure. This commit addresses these issues.
