It can happen that the list of healthy hosts is empty, then we get one from the blacklist. but some other operation might have sneaked in and emptied the blacklist in the meantime, so we have to retry till we manage to get some host, either from the healthy list or from the blacklist.
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.

* 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.
Relates #19505
The ThreadPool#scheduleWithFixedDelay method does not make it clear that all scheduled runnable instances
will be run on the scheduler thread. This becomes problematic if the actions being performed include
blocking operations since there is a single thread and tasks may not get executed due to a blocking task.
This change includes a few different aspects around trying to prevent this situation. The first is that
the scheduleWithFixedDelay method now requires the name of the executor that should be used to execute
the runnable. All existing calls were updated to use Names.SAME to preserve the existing behavior.
The second aspect is the removal of using ScheduledThreadPoolExecutor#scheduleWithFixedDelay in favor of
a custom runnable, ReschedulingRunnable. This runnable encapsulates the logic to deal with rescheduling a
runnable with a fixed delay and mimics the behavior of executing using a ScheduledThreadPoolExecutor and
provides a ScheduledFuture implementation that also mimics that of the typed returned by a
ScheduledThreadPoolExecutor.
Finally, an assertion was added to BaseFuture to detect blocking calls that are being made on the scheduler
thread.
When looking at the logstash template, I noticed that it has definitions for
dynamic temilates with `match_mapping_type` equal to `byte` for instance.
However elasticsearch never tries to find templates that match the byte type
(only long or double as far as numbers are concerned). This commit changes
template parsing in order to ignore bad values of `match_mapping_type` (given
how the logstash template is popular, this would break many upgrades
otherwise). Then I hope to fail the parsing on bad values in 6.0.
We throw IOException, which is the exception that is going to be thrown in 99% of the cases. A more generic exception can happen, and if it is a runtime one we just let it bubble up as is, otherwise we wrap it into runtime one so that we don't require to catch Exception everywhere, which seems odd.
Also adjusted javadocs for all performRequest methods
We keep the default async client behaviour like in BasicAsyncResponseConsumer, but we lower the maximum size of the buffer from Integer.MAX_VALUE (2GB) to 10 MB. This way users will realize they are buffering big responses in heap hence they'll know they have to do something about it, either write their own response consumer or increase the buffer size limit by providing their manually creeted instance of HeapBufferedAsyncResponseConsumer (constructor accept a bufferLimit int argument).
