If a node fails to forward a master node operation to the current master, it will schedule a retry using a listener for cluster state changes. Once the listener is in place (and future changes are guaranteed to be observed) it will double check nothing has change during the addition of the listener. This check has previously been change to use cluster state versions (see: #5499). This is however not reliable solution as master elections (which change the master) do not increment the cluster state version and thus could be missed. This commit changes the check to use reference equality making it stricter.
Closes#5548
Although high-severity bugs were mostly static variables that were not final,
it also found potential NPEs and bugs like `x ^= x;` or equality checks on
objects that don't share a common interface.

For around 10% of the calls that support the GET method, the request body gets now sent as `source` parameter with GET method (no randomized method in this case).
This way we can find bugs like #5556 (missing support for source param).
Some tests disable refresh and verify that documents cannot be found without an explicit refresh. With at least one replica and waiting for yellow though, it can happen that we start indexing docs when the replicas are not ready yet, and as soon as they become ready they get refreshed, causing the newly added docs to be unexpectedly found. Solution is to disable replicas for these specific tests.
The `field_value_factor` function uses the value of a field in the
document to influence the score.
A query that looks like:
{
"query": {
"function_score": {
"query": {"match": { "body": "foo" }},
"functions": [
{
"field_value_factor": {
"field": "popularity",
"factor": 1.1,
"modifier": "square"
}
}
],
"score_mode": "max",
"boost_mode": "sum"
}
}
}
Would have the score modified by:
square(1.1 * doc['popularity'].value)
Closes#5519
allow to configure on the index level which blocks can optionally be applied using tribe.blocks.indices prefix settings.
allow to control what will be done when a conflict is detected on index names coming from several clusters using the tribe.on_conflict setting. Defaults remains "any", but now support also "drop" and "prefer_[tribeName]".

We have had a couple of bugs because of the use of these methods without paying
attention that it might return a negative value when provided with MIN_VALUE.
There is one common and legitimate usage of this method in order to perform
a modulo operation which would always return a positive number. This use-case
has been extracted to MathUtils.mod.
Close#5562
* Only run the test with one node, to make sure only a single purger thread is running.
* Instead of generating the _timestamp upon indexing in ES, define the _timestamp in the documents.
* Verify the responses from the index requests.
This is the first to make it possible to have a different impl of TestCluster (e.g. based on an external cluster) that has the same methods but a different impl for them (e.g. it might use the REST API to do the same instead of the Java API)
Closes#5542
