All query builders written as self contained xContent objects, to we should mark
them accordingly using ToXContentObject. This also makes it possible to use
things like XContentHelper#toXContent to render query builders in tests.
* Adds rewrite phase to aggregations
This change adds aggregations to the rewrite performed by the `SearchSourceBuilder`. This means that `AggregationBuilder`s are able to implement a `rewrite()` method where they can return a new `AggregationBuilder` which is functionally the same but in a more primitive form. This is exactly analogous to the rewrite done by the `QueryBuilder`s.
The first aggregation to implement the rewrite are the filter and filters aggregations so they can rewrite the filters they contain.
Closes#17676
* Removes rewrite from PipelineAggregationBuilder
Rewrite is based on shard level information. Since pipeline aggregation are run in the reduce phase it doesn’t make sense to rewrite them on the shards. In fact eventually we shouldn’t be transporting them to the shards at all and should be retaining them on the coordinating node for execution in the reduce phase
* Addresses review comments
* addresses more review comments
* Fixed imports
The constructor using `types` has been deprecated for a while now (starting with
ES 5.1.). It can be removed in the next mayor version. Since types are optional
they should be added with the #types() setter.
* Adds check for negative search request size
This change adds a check to `SearchSourceBuilder` to throw and exception if the size set on it is set to a negative value.
Closes#22530
* fix error in reindex
* update re-index tests
* Addresses review comment
* Fixed tests
* Added random negative size test

This commit converts the low level client and high level client chapters into two parts, which allows each high level client supported api to be on a separate page and show up in the index on the right.
QueryParseContext is currently only used as a wrapper for an XContentParser, so
this change removes it entirely and changes the appropriate APIs that use it so
far to only accept a parser instead.
We have two ways to filter XContent:
- The first method is to parse the XContent as a map and use
XContentMapValues.filter(). This method filters the content of the map
using an automaton. It is used for source filtering, both at search and
indexing time. It performs well but can generate a lot of objects and
garbage collections when large XContent are filtered. It also returns
empty objects (see f2710c16eb) when all
the sub fields have been filtered out and handle dots in field names as
if they were sub fields.
- The second method is to parse the XContent and copy the XContentParser
structure to a XContentBuilder initialized with includes/excludes
filters. This method uses the Jackson streaming filter feature. It is
used by the Response Filtering ('filter_path') feature. It does not
generate a lot of objects, and does not return empty objects and also
does not handle dots in field names explicitely.
Both methods have similar goals but different tests. This commit changes
the current XContentBuilder test class so that it becomes a more generic
testing class and we can now ensure that filtering methods generate the
same results.
It also removes some tests from the XContentMapValuesTests class that
should be in XContentParserTests.
The significance aggs return Lucene index-level statistics that when merged are assumed to be from different shards. The Aggregator unit tests assume segments can be treated as shards and thus break the significance stats and introduce double-counting of background doc frequencies. This change addresses this problem by ensuring test indexes have only one shard.
Closes#25429
If all nodes get disconnected before we can send the request we might
try to reconnect and that will fail with an ISE instead of the a transport
exception.
Closes#25301
ensureYellow ensures at least yellow.
Also, since we only have 1 replica, we don't need to index for it to know about the primary term promotion
Closes#25287
This commit makes the use of the global network settings explicit instead
of implicit within NetworkService. It cleans up several places where we fall
back to the global settings while we should have used tcp or http ones.
In addition this change also removes unnecessary settings classes
The replica replication response object has an extra allocationId field that contains the allocation id of the replica on which the request was executed. As we are sending the allocation id with the actual replica replication request, and check when executing the replica replication action that the allocation id of the replica shard is what we expect, there is no need to communicate back the allocation id as part of the response object.
This commit adjusts the BWC version on the bad cluster allocation
explain request test as changing the API to respond with a bad request
status instead of an internal server error status was backported to 5.x
to be included in 5.6.0.

Hadoop 2.7.x libraries fail when running on JDK9 due to the version string changing to a single
character. On Hadoop 2.8, this is no longer a problem, and it is unclear on whether the fix will be
backported to the 2.7 branch. This commit upgrades our dependency of Hadoop for the HDFS
Repository to 2.8.1.
When a user requests a cluster allocation explain in a situation where
it does not make sense (for example, there are no unassigned shards), we
should consider this a bad request instead of a server error. Yet, today
by throwing an illegal state exception, these are treated as server
errors. This commit adjusts these so that they throw illegal argument
exceptions and are treated as bad requests.

This commit adds a note to the docs regarding explicilty setting a
publish host if the network.host setting results in multiple bind
addresses.
Relates #25496
This commit adds a test for a scenario where a replica receives an extra
document that the promoted replica does not receive, misses the
primary/replica re-sync, and the recovers from the newly-promoted
primary.
Relates #25493
Failing to do so can cause other errors later on during query execution.
For example if `WrapperQueryBuilder` wraps a `GeoShapeQueryBuilder` that fetches the shape from an index then it will skip the shape fetching
and fail later with the error that no shapes have been fetched.

This commit adds an LRU set to used to determine if a keyed deprecation
message should be written to the deprecation logs, or only added to the
response headers on the thread context.

We have various assertions that check we never block on transport
threads. This commit adds the thread names for the NioTransport to
these assertions.
With this change I had to fix two places where we were calling blocking
methods from the transport threads.
This commit adds additional protection to `ESSelector` and its
implementations to ensure that channels are not enqueued after the
selector is closed.
After a channel has been added to the queue, we check that the selector
is open. If it is not, then we remove the channel from the queue. If the
channel is removed successfully, we throw an `IllegalStateException`.
These settings have not be working for a full major version since they
are not registered. Given that they are simply duplicates we can just remove
them.
Our current TCPTransport logic assumes that we do not pass pings to
the TCPTransport level.
This commit fixes an issue where NioTransport was passing pings to
TCPTransport and leading to exceptions.
