The filter element has been deprecated in the function_score query parser. Whenever a filter is found it gets wrapped into a query automatically. The filter in the java api builder is always null, there is no way to set its value, just a leftover.
The initial implementation of two phase commit based cluster state publishing (#13062) relied on a single in memory "pending" cluster state that is only processed by ZenDiscovery once committed by the master. While this is fine on it's own, it resulted in an issue with acknowledged APIs, such as the open index API, in the extreme case where a node falls behind and receives a commit message after a new cluster state has been published. Specifically:
1) Master receives and acked-API call and publishes cluster state CS1
2) Master waits for a min-master nodes to receives CS1 and commits it.
3) All nodes that have responded to CS1 are sent a commit message, however, node N didn't respond yet
4) Master waits for publish timeout (defaults to 30s) for all nodes to process the commit. Node N fails to do so.
5) Master publishes a cluster state CS2. Node N responds to cluster state CS1's publishing but receives cluster state CS2 before the commit for CS1 arrives.
6) The commit message for cluster CS1 is processed on node N, but fails because CS2 is pending. This caused the acked API in step 1 to return (but CS2 , is not yet processed).
In this case, the action indicated by CS1 is not yet executed on node N and therefore the acked API calls return pre-maturely. Note that once CS2 is processed but the change in CS1 takes effect (cluster state operations are safe to batch and we do so all the time).
An example failure can be found on: http://build-us-00.elastic.co/job/es_feature_two_phase_pub/314/
This commit extracts the already existing pending cluster state queue (processNewClusterStates) from ZenDiscovery into it's own class, which serves as a temporary container for in-flight cluster states. Once committed the cluster states are transferred to ZenDiscovery as they used to before. This allows "lagging" cluster states to still be successfully committed and processed (and likely to be ignored as a newer cluster state has already been processed).
As a side effect, all batching logic is now extracted from ZenDiscovery and is unit tested.
This commit removes and now forbids all uses of
com.google.common.collect.Queues across the codebase. This is one of
many steps in the eventual removal of Guava as a dependency.

The MockInternalClusterInfoService depends on a constant and helper
method from actual test cases. This moves the constant and helper method
into the mock itself. Without this change, the classes put into the test
jar are not completely useable on their own (since this mock is in the
test jar, but the test cases are not).

The semantics of the `boost` parameter for `function_score` changed. This is
due to the fact that Lucene now requires that query boosts and top-level boosts
are applied the same way.
Requesting a million hits, or page 100,000 is always a bad idea, but users
may not be aware of this. This adds a per-index limit on the maximum size +
from that can be requested which defaults to 10,000.
This should not interfere with deep-scrolling.
Closes#9311
The AWS plugin was broken into discovery-ec2 and repository-s3 so we can't
test the old plugin and must test the new ones.
Fixed some wording issues in test names.
This changes the packaging tests to start Elasticsearch with all plugins
installed and checks `_cat/plugins?h=c` against the list of plugins in
the plugins directory. If the list differs, error! So it proves that the
plugins can be installed using bin/plugin as shipped in the rpm and deb
packages.
Closes#13254
There are two other obvious ways to implement the "packages don't start
elasticsearch" checks but when you work through them they aren't as nice
as the implementation of the checks that we use now. This just adds
documentation to that effect.
We don't want either the deb or rpm package to start elasticsearch as soon
as they install nor do we want the package to register elasticsearch to
start on restart. That action is reserved for the administrator. This adds
tests for that.
Closes#13122
