EvillPeerRecoveryIT checks scenario where recovery is happening while there are on going indexing operation that already have been assigned a seq# . This is fairly hard to achieve and the test goes through a couple of hoops via the plugin infra to achieve that. This PR extends the unit tests infra to allow for those hoops to happen in unit tests. This allows the test to be moved to RecoveryDuringReplicationTests

This changes removes the SearchResponseListener that was used by the ExpandCollapseSearchResponseListener to expand collapsed hits.
The removal of SearchResponseListener is not a breaking change because it was never released.
This change also replace the blocking call in ExpandCollapseSearchResponseListener by a single asynchronous multi search request. The parallelism of the expand request can be set via CollapseBuilder#max_concurrent_group_searches
Closes#23048
Now that we use bulk for single item indexing, this is often the case. Having an indicator of the id of the indexed document helps debugging.
It now looks like this `BulkShardRequest to [[test][0]] containing [index {[test][type][AVojzy9ZxfWASZ-ysmN7], source[{"auto":true}]}]`
Empty response bodies should only be sent for HEAD requests, otherwise we should always send back info about the exception that was thrown. Removed some manual exception handling in the REST action that should be rather bubbled up and handled by our rest action infra like every other rest action does.
Netty 4.1.8 wraps connect and accept operations in doPrivileged blocks.
This means that we not need to give permissions to the entire transport
module. Additionally this commit deletes the privileged socket channel
and privileged server socket chanel.
This pull request adds a new parameter to the REST Search API named `typed_keys`. When set to true, the aggregation names in the search response will be prefixed with a prefix that reflects the internal type of the aggregation.
Here is a simple example:
```
GET /_search?typed_keys
{
"aggs": {
"tweets_per_user": {
"terms": {
"field": "user"
}
}
},
"size": 0
}
```
And the response:
```
{
"aggs": {
"sterms:tweets_per_user": {
...
}
}
}
```
This parameter is intended to make life easier for REST clients that could parse back the prefix and could detect the type of the aggregation to parse. It could also be implemented for suggesters.
Today we account for too many response with an `IllegalStateException` in
`AbstractSearchAsyncAction` while this is something that should never happen
we should rather assert that we are always have less or equal the number of
expected ops when waiting for responses.
This commit removes support for the `application/x-ldjson` Content-Type header as this was only used in the first draft
of the spec and had very little uptake. Additionally, the docs for bulk and msearch have been updated to specifically
call out ndjson and mention that the newline character may be preceded by a carriage return.
Finally, the bulk request handling of the carriage return has been improved to remove this character from the source.
Closes#23025
This is just a temporary fix until #23048 is fixed. FieldCollapsing
is executing blocking calls on a network thread which causes potential deadlocks
and trips assertions.

We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.
After the first cluster state from a new master is processed, NodeConnectionService guarantees we connect to the new master. This removes the need to explicitly connect to the master in the MasterFaultDetection code making it simpler and bypasses the assertion triggered due to the blocking operation on the cluster state thread.

Today we carry on all search results including aggs, suggest and profile results
until we have successfully fetched all hits for the search request. This can potentially
hold on to a large amount of memory if there are heavy aggregations involved. With
this change aggs and profiles are entirely consumed an released for GC before the fetch
phase is executing. This is a first step towards reducing results on-the-fly if the number
of non-empty response are large.
Elasticsearch v5.0.0 uses allocation IDs to safely allocate primary shards whereas prior versions of ES used a version-based mode instead. Elasticsearch v5 still has support for version-based primary shard allocation as it needs to be able to load 2.x shards. ES v6 can drop the legacy support.
Since `_all` is now deprecated and cannot be set for new indices, we should also
disallow any field that has the `include_in_all` parameter set.
Resolves#22923
These need to be CONSOLEified *now* because we're starting to
require Content-Type headers and they didn't have any.
* cluster/reroute: Marked as CONSOLE but skipped because the docs
build runs with a single node.
* docs/bulk: Marked as NOTCONSOLE because the snippets describe
either examples or `curl` commands. Fixed the `curl` command to
include the `Content-Type` header.
* query-dsl/terms-query: Marked as CONSOLE.
* search/request/rescore: Marked as CONSOLE. Fixed deprecated
syntax.

This adds the `COPY AS CURL` and `VIEW IN CONSOLE` links to the docs
and causes the snippets to be tested during Elasticsearch's build.

This is related to #22116. This commit adds calls that require
SocketPermission connect to forbidden APIs.
The following calls are now forbidden:
- java.net.URL#openStream()
- java.net.URLConnection#connect()
- java.net.URLConnection#getInputStream()
- java.net.Socket#connect(java.net.SocketAddress)
- java.net.Socket#connect(java.net.SocketAddress, int)
- java.nio.channels.SocketChannel#open(java.net.SocketAddress)
- java.nio.channels.SocketChannel#connect(java.net.SocketAddress)
#22194 gave us the ability to open low level temporary connections to remote node based on their address. With this use case out of the way, actual full blown connections should validate the node on the other side, making sure we speak to who we think we speak to. This helps in case where multiple nodes are started on the same host and a quick node restart causes them to swap addresses, which in turn can cause confusion down the road.
This adds the `COPY AS CURL` and `VIEW IN CONSOLE` buttons to the
docs and makes the build execute the snippets as part of `docs:check`.

This is related to #23020. There are some cases for where this method
might be called with a URL to a file inside a jar. This commit allows
this method to read URLs with a protocol of 'jar:/'.
Secure settings from the elasticsearch keystore were not yet validated.
This changed improves support in Settings so that secure settings more
seamlessly blend in with normal settings, allowing the existing settings
validation to work. Note that the setting names are still not validated
(yet) when using the elasticsearc-keystore tool.
Painless uses Ruby-like method dispatch (reciever type, method name,
and arity) rather than Java-like (reciever type, method name, and
argument compile time types) or Groovy-like method dispatch (receiver
type, method name, and argument run time types). We do this for
mostly good reasons but we never documented it.
Relates to #22720
As part of #22116 we are going to forbid usage of api
java.net.URL#openStream(). However in a number of places across the
we use this method to read files from the local filesystem. This commit
introduces a helper method openFileURLStream(URL url) to read files
from URLs. It does specific validation to only ensure that file:/
urls are read.
Additionlly, this commit removes unneeded method
FileSystemUtil.newBufferedReader(URL, Charset). This method used the
openStream () method which will soon be forbidden. Instead we use the
Files.newBufferedReader(Path, Charset).
