Today we try to be smart and make a generic decision if an exception should
be treated as a document failure but in some cases concurrency in the index writer
make this decision very difficult since we don't have a consistent state in the case
another thread is currently failing the IndexWriter/InternalEngine due to a tragic event.
This change simplifies the exception handling and makes specific decisions about document failures
rather than using a generic heuristic. This prevent exceptions to be treated as document failures
that should have failed the engine but backed out of failing since since some other thread has
already taken over the failure procedure but didn't finish yet.
Similar to the Filters aggregation but only supports "keyed" filter buckets and automatically "ANDs" pairs of filters to produce a form of adjacency matrix.
The intersection of buckets "A" and "B" is named "A&B" (the choice of separator is configurable). Empty intersection buckets are removed from the final results.

This is related to #22116. Core no longer needs SocketPermission
accept. This permission is relegated to the transport-netty4 module
and (for tests) to the mocksocket jar.
By default, the JVM GC log file grows without
limitation. This is inconvenient for a long running
process like Elasticsearch.
With this commit we add an example configuration
for a rotating GC log in `conig/jvm.options`.
Those services validate their setting before submitting an AckedClusterStateUpdateTask to the cluster state service. An acked cluster state may be completed by a networking thread when the last acks as received. As such it needs special care to make sure that thread context headers are handled correctly.
Makes `PainlessLexer` abstract and adds the hacks that it needs as abstract methods implemented in `EnhancedPainlessLexer`. This feels a little cleaner than referencing the hacks statically.
* S3 repository: Deprecate specifying credentials through env vars and sys props
This is a follow up to #22479, where storing credentials secure way was
added.
This commit fixes an issue with deprecation logging for lenient
booleans. The underlying issue is that adding deprecation logging for
lenient booleans added a static deprecation logger to the Settings
class. However, the Settings class is initialized very early and in CLI
tools can be initialized before logging is initialized. This leads to
status logger error messages. Additionally, the deprecation logging for
a lot of the settings does not provide useful context (for example, in
the token filter factories, the deprecation logging only produces the
name of the setting, but gives no context which token filter factory it
comes from). This commit addresses both of these issues by changing the
call sites to push a deprecation logger through to the lenient boolean
parsing.

This commit adds a MessyRestTestPlugin to the gradle build. It extends
StandaloneRestTestPlugin. The main piece of functionality that it adds
is to copy plugin-metadata from dependencies into the
generated-resources for the current test source. This is necessary to
ensure that permissions for dependencies are applied when running the
tests.
A current limitation is that the permissions are applied differently
than in the distribution sources. When permissions are granted to all
depedencies for a module or plugin, the permissions are granted to all
dependencies on the classpath for tests besides a few hardcoded
exclusions:
- es core
- es test framework
- lucene test framework
- randomized runner
- junit library
In preparation for being able to parse SearchResponse from its rest representation
for the java rest client, this adds fromXContent to SearchProfileShardResults and its
nested classes.
Adds unit tests for the `filters` aggregation.
This change also adds an helper to search and reduce any aggregator in a unit test.
This is done by dividing a single searcher in sub-searcher, one for each segment.

We don't want to expose `String#getBytes` which is required for
`Base64.getEncoder.encode` to work because we're worried about
character sets. This adds `encodeBase64` and `decodeBase64`
methods to `String` in Painless that are duals of one another
such that:
`someString == someString.encodeBase64().decodeBase64()`.
Both methods work with the UTF-8 encoding of the string.
Closes#22648
* Fix NPE on FieldStats with mixed cluster on version pre/post 5.2
In 5.2 the FieldStats API can return null min/max values.
These values cannot be deserialized by a node with version pre 5.2 so if this node
is pick to coordinate a FieldStats request in a mixed cluster an NPE can be thrown.
This change prevents the NPE by removing the non serializable FieldStats object directly in the field stats shard request.
The filtered fields will not be present in the response when a node pre 5.2 acts as a coordinating node.
This change is a simple adaptation of https://github.com/elastic/elasticsearch/pull/19587 for the current state of master.
It allows to define search response listener in the form of `BiConsumer<SearchRequest, SearchResponse>`s in a search plugin.
This changes build files so that building Elasticsearch works with both Gradle 2.13 as well as higher versions of Gradle (tested 2.14 and 3.3), enabling a smooth transition from Gradle 2.13 to 3.x.
This PR removes all leniency in the conversion of Strings to booleans: "true"
is converted to the boolean value `true`, "false" is converted to the boolean
value `false`. Everything else raises an error.
Everything that extended `AbstractAsyncBulkByScrollAction` also
extended `AbstractAsyncBulkIndexByScrollAction` so this removes
`AbstractAsyncBulkIndexByScrollAction`, merging it into
`AbstractAsyncBulkByScrollAction`.
Changes the error message when `action.auto_create_index` or
`index.mapper.dynamic` forbids automatic creation of an index
from `no such index` to one of:
* `no such index and [action.auto_create_index] is [false]`
* `no such index and [index.mapper.dynamic] is [false]`
* `no such index and [action.auto_create_index] contains [-<pattern>] which forbids automatic creation of the index`
* `no such index and [action.auto_create_index] ([all patterns]) doesn't match`
This should make it more clear *why* there is `no such index`.
Closes#22435
testAckedIndexing now waits for all nodes to stabilize in the cluster
state through an assertBusy before final validation that all documents
are found in tehir respective shards in the cluster. Before, what could
happen is that the ensureGreen check passes but only after that is a
ping failure from the network disruption processed by the master,
thereby rendering the cluster RED again. This assertBusy waits up to 30
seconds for all nodes to have stabilized and all get document actions to
succeed.
This is related to #22116. Certain plugins (discovery-azure-classic,
discovery-ec2, discovery-gce, repository-azure, repository-gcs, and
repository-s3) open socket connections. As SocketPermissions are
transitioned out of core, these plugins will require connect
permission. This pull request wraps operations that require these
permissions in doPrivileged blocks.
Today we do not preserve response headers if they are present on a transport protocol
response. While preserving these headers is not always desired, in the most cases we
should pass on these headers to have consistent results for depreciation headers etc.
yet, this hasn't been much of a problem since most of the deprecations are detected early
ie. on the coordinating node such that this bug wasn't uncovered until #22647
This commit allow to optionally preserve headers when a context is restored and also streamlines
the context restore since it leaked frequently into the callers thread context when the callers
context wasn't restored again.
Relates to #22024
On top of documentation, the PR adds deprecation loggers and deals with the resulting warning headers.
The yaml test is set exclude versions up to 6.0. This is need to make sure bwc tests pass until this is backported to 5.2.0 . Once that's done, I will change the yaml test version limits
