Adds the option for a plugin to specify extra directories containing notices
and licenses files to be incorporated into the overall notices file that is
generated for the plugin.
This can be useful, for example, where the plugin has a non-Java dependency
that itself incorporates many 3rd party components.
The getProperty method is an internal method needed to run pipeline aggregations and retrieve info by path from the aggs tree. It is not needed in the MultiBucketsAggregation.Bucket interface, which is returned to users running aggregations from the transport client. The method is moved to the InternalMultiBucketAggregation class as that's where it belongs.
The `getProperty` method is an internal method needed to run pipeline aggregations and retrieve info by path from the aggs tree. It is not needed in the `Aggregations` interface, which is returned to users running aggregations from the transport client. Furthermore, the method is currenty unused by pipeline aggs too, as only InternalAggregation#getProperty is used. It can then be removed
We deprecated this method in the past because we thought it was a temporary thing that could go away over time. We radically trimmed down the usages of a context while parsing when we got rid of the ParseFieldMatcher, but the usages that are left are legit and we will hardly get rid of them. Also, working on aggs parsing we will need a context to carry around the aggregation name that gets parsed through XContentParser#namedObject .
The buffer limit should have been configurable already, but the factory constructor is package private so it is truly configurable only from the org.elasticsearch.client package. Also the HttpAsyncResponseConsumerFactory interface was package private, so it could only be implemented from the org.elasticsearch.client package.

After two nodes are being stopped and two more are joining the cluster, we first have to wait on the cluster to consist of the right nodes before
waiting on green status, otherwise we might get a green status for a cluster with dead nodes.
We had a couple of unfortunate field name collisions in our CI, where the json duplicate check tripped. Increasing the minimum length of randomly generated field names should decrease the chance of this issue happening again.
_field_stats has evolved quite a lot to become a multi purpose API capable of retrieving the field capabilities and the min/max value for a field.
In the mean time a more focused API called `_field_caps` has been added, this enpoint is a good replacement for _field_stats since he can
retrieve the field capabilities by just looking at the field mapping (no lookup in the index structures).
Also the recent improvement made to range queries makes the _field_stats API obsolete since this queries are now rewritten per shard based on the min/max found for the field.
This means that a range query that does not match any document in a shard can return quickly and can be cached efficiently.
For these reasons this change deprecates _field_stats. The deprecation should happen in 5.4 but we won't remove this API in 6.x yet which is why
this PR is made directly to 6.0.
The rest tests have also been adapted to not throw an error while this change is backported to 5.4.
This commit adds support for incremental top N reduction if the number of
expected shards in the search request is high enough. The changes here
also clean up more code in SearchPhaseController to make the separation
between values that are the same on each search result and values that
are per response. The reduced search phase result doesn't hold an arbitrary
result to obtain values like `from`, `size` or sort values which is now
cleanly encapsulated.
The refactoring in #23711 hardcoded version logic for replica to assume monotonic versions. Sadly that's wrong for `FORCE` and `VERSION_GTE`. Instead we should use the methods in VersionType to detect conflicts.
Note - once replicas use sequence numbers for out of order delivery, this logic goes away.
This commit upgrades the Log4j dependencies from version 2.7 to version
2.8.2. This release includes a fix for a case where Log4j could lose
exceptions in the presence of a security manager.

The ExtrasFS filesystem creates extra directories when creating temp
directories during tests to ensure that Lucene does not care about extra
files. These extra files get in our way in the plugins service tests
because some of these tests are counting only on certain directories
existing. This commit suppresses the ExtrasFS filesystem for the plugins
service tests, and fixes a test that was passing for the wrong reason
(because of the existence of an extra directory from ExtrasFS).
This commit removes some leniency from the plugin service which skips
hidden files in the plugins directory. We really want to ensure the
integrity of the plugin folder, so hasta la vista leniency.

This commit removes the "legacy" feature of secure settings, which setup
a parallel setting that was a fallback in the insecure
elasticsearch.yml. This was previously used to allow the new secure
setting name to be that of the old setting name, but is now not in use
due to other refactorings. It is much cleaner to just have all secure
settings use new setting names. If in the future we want to reuse the
previous setting name, once support for the insecure settings have been
removed, we can then rename the secure setting. This also adds a test
for the behavior.
This change adds secure settings for access/secret keys and proxy
username/password to ec2 discovery. It adds the new settings with the
prefix `discovery.ec2`, copies other relevant ec2 client settings to the
same prefix, and deprecates all other settings (`cloud.aws.*` and
`cloud.aws.ec2.*`). Note that this is simpler than the client configs
in repository-s3 because discovery is only initialized once for the
entire node, so there is no reason to complicate the configuration with
the ability to have multiple sets of client settings.

reindex_from_remote was using `TimeValue#toString` to generate the
scroll timeout which is bad because that generates fractional
time values that are useful for people but bad for Elasticsearch
which doesn't like to parse them. This switches it to using
`TimeValue#getStringRep` which spits out whole time values.

Makes #23828 even more desirable
Empty meta gets printed out, which means that if the request contains an empty meta object, that is returned with the response as well. On the other hand null, meaning when the object is not in the request, is not printed out. ParsedAggregation used to not print out empty metadata, and didn't allow the null value. Aligned behaviour to the existing behaviour from InternalAggregation.
They needed to be updated now that Painless is the default and
the non-sandboxed scripting languages are going away or gone.
I dropped the entire section about customizing the classloader
whitelists. In master this barely does anything (exposes more
things to expressions).
This test was sporadically failing for the following reason:
- 4 nodes (nodes 0, 1, 2, and 3) running with `minimum_master_nodes` set to 3
- we stop 2 nodes (node 0 and 3)
- wait for cluster block to be in place on all nodes
- start 2 nodes (node 4 and node 5) and do a `prepareHealth().setWaitForNodes("4")`
- then do a search request
The search request runs into the `ClusterBlockException` as the `prepareHealth().setWaitForNodes("4")` check succeeds on a cluster state that has
nodes 1, 2, 3, and 4, i.e., only one of the two new nodes has joined the cluster and only one of the two dead nodes was removed by the master
(removing the dead nodes only happens after there are again `minimum_master_nodes` nodes in the cluster).
This commit fixes the issue by reusing a method from InternalTestCluster that checks that the right nodes have rejoined the cluster.
The test assumes that two nodes leaving the cluster results in two cluster state updates on the master, which is invalidated by cluster state
batching.
Shuffling xContent breaks the order of the highlighter fields in the
internal list if the highlighter doesn't use the array syntax. In other tests we
avoid shuffling this json level, but since this is done in the base test for
aggregations we should ensure the highlight builder uses the array syntax here.
This commit fixes the handling of POSIX permissions on Windows in the
spawner tests. Since POSIX permissions do not exist there, we first have
to check if we are on a filesystem that supports POSIX or not before
attempting to set the permissions.
The `getProperty` method is an internal method needed to run pipeline aggregations and retrieve info by path from the aggs tree. It is not needed in the `Aggregation` interface, which is returned to users running aggregations from the transport client. The method is moved to the InternalAggregation class as that's where it belongs.
ESTestCase has methods to shuffle xContent keys given a builder or a parser. Shuffling wasn't actually doing what was expected but rather reordering the keys in their natural ordering, hence the output was always the same at every run. Corrected that and added tests, also fixed a couple of tests that were affected by this fix.
Before now ranges where forbidden, because the percolator query itself could get cached and then the percolator queries with now ranges that should no longer match, incorrectly will continue to match.
By disabling caching when the `percolator` is being used, the percolator can now correctly support range queries with now based ranges.
I think this is the right tradeoff. The percolator query is likely to not be the same between search requests and disabling range queries with now ranges really disabled people using the percolator for their use cases.
Also fixed an issue that existed in the percolator fieldmapper, it was unable to find forbidden queries inside `dismax` queries.
Closes#23859
If a snapshot is taken on multiple indices, and some of them are "good"
indices that don't contain any corruption or failures, and some of them
are "bad" indices that contain missing shards or corrupted shards, and
if the snapshot request is set to partial=false (meaning don't take a
snapshot if there are any failures), then the good indices will not be
snapshotted either. Previously, when getting the status of such a
snapshot, a 500 error would be thrown, because the snap-*.dat blob for
the shards in the good index could not be found.
This commit fixes the problem by reporting shards of good indices as
failed due to a failed snapshot, instead of throwing the
NoSuchFileException.
Closes#23716
Currently, both the Amazon S3 client provides a retry mechanism, and the
S3 blob store also attempts retries for failed read/write requests.
Both retry mechanisms are controlled by the
`repositories.s3.max_retries` setting. However, the S3 blob store retry
mechanism is unnecessary because the Amazon S3 client provided by the
Amazon SDK already handles retries (with exponential backoff) based on
the provided max retry configuration setting (defaults to 3) as long as
the request is retryable. Hence, this commit removes the unneeded retry
logic in the S3 blob store and the S3OutputStream.
Closes#22845
