This commit removes an undocumented output parameter output_uuid from
the cluster stats API. Currently the parameter does not even work as it
is not whitelisted as an output parameter. Since the cluster UUID is
available from the main action, and this parameter is not documented, we
opt to just remove it.

This allows you to whitelist `localhost:*` or `127.0.10.*:9200`.
It explicitly checks for patterns like `*` in the whitelist and
refuses to start if the whitelist would match everything. Beyond
that the user is on their own designing a secure whitelist.
`LocalDiscovery` is a discovery implementation that uses static in memory maps to keep track of current live nodes. This is used extensively in our tests in order to speed up cluster formation (i.e., shortcut the 3 second ping period used by `ZenDiscovery` by default). This is sad as that mean that most of the test run using a different discovery semantics than what is used in production. Instead of replacing the entire discovery logic, we can use a similar approach to only shortcut the pinging components.
When running `gradle run`, a developer usually intends to get a running
instance as if they had run elasticsearch from the command line. This is
different than the isolated environment we use for integration testing
plugins. This change switches the run task to use the zip distribution,
so that all modules included in the normal distribution are included.
This tests that the templates shipped with 5.0 versions of Logstash and
Beats still work on an Elasticsearch 6.0+ node, so that we ensure that
ES can be upgraded prior to upgrading tools dependent on it.

* Only negate index expression on all indices with preceding wildcard
There is currently a very confusing behavior in Elasticsearch for the
following:
Given the indices: `[test1, test2, -foo1, -foo2]`
```
DELETE /-foo*
```
Will cause the `test1` and `test2` indices to be deleted, when what is
usually intended is to delete the `-foo1` and `-foo2` indices.
Previously we added a change in #20033 to disallow creating indices
starting with `-` or `+`, which will help with this situation. However,
users may have existing indices starting with these characters.
This changes the negation to only take effect in a wildcard (`*`) has
been seen somewhere in the expression, so in order to delete `-foo1` and
`-foo2` the following now works:
```
DELETE /-foo*
```
As well as:
```
DELETE /-foo1,-foo2
```
so in order to actually delete everything except for the "foo" indices
(ie, `test1` and `test2`) a user would now issue:
```
DELETE /*,--foo*
```

Updating the circuit breaker settings (and other settings) should always be possible, even if the cluster is under stress. With #20827 we updated the cluster settings request to not trigger circuit breakers. However that change is not complete since the resulting cluster state can potentially not be published. This change makes sure cluster state publishing to not trigger circuit breakers as well.
Relates to #20960 where this was discovered.
Cleaning up a few remaining occurences of using junits ExpectedException rule in
favor of using LuceneTestCase#expectThrows() which is more concise and versatile.
* Scripting: Add support for booleans in scripts
Since 2.0, booleans have been represented as numeric fields (longs).
However, in scripts, this is odd, since you expect doing a comparison
against a boolean to work. While languages like groovy will auto convert
between booleans and longs, painless does not.
This changes the doc values accessor for boolean fields in scripts to
return Boolean objects instead of Long objects.

* Make Booleans final and remove wrapping of `this` for getValues()
The create request now requires that an ID be present.
Currently the clients hard code a create method, but
we should just add a create REST spec so this method
can be autogenerated.
This commit fixes two issues with the slow log docs:
- clarifies that these settings are per index
- updates index slow log configuration for Log4j 2

During a recent merge from master, we lost the bridge from IndicesClusterStateService to the GlobalCheckpointService of primary shards, notifying them of changes to the current set of active/initializing shards. This commits add the bridge back (with unit tests). It also simplifies the GlobalCheckpoint tracking to use a simpler model (which makes use the fact that the global check point sync is done periodically).
The old integration CheckpointIT test is moved to IndexLevelReplicationTests. I also added similar assertions to RelocationsIT, which surfaced a bug in the primary relocation logic and how it plays with global checkpoint updates. The test is currently await-fixed and will be fixed in a follow up issue.
This commit changes the current REST API parser to make it fail and throw an exception when a REST specification file contains a duplicated parameters, or path, or method, or path part.
This commit fixes an issue with the handling of the value "keep-alive"
on the Connection header in the Netty 4 HTTP implementation while
handling an HTTP 1.0 request. The issue was using the wrong equals
method to compare an AsciiString instance and a String instance (they
could never be equal). This commit fixes this to use the correct equals
method to compare for content equality.

This is important to allow any test to use RandomQueryBuilder#createQuery()
since some of the query builders that are used in this test test the length
of the types array and otherwise will thow NPE if the test is not a subclass
of AbstractQueryTestCase.
Today when logging an unknown or invalid setting, the log message does
not contain the source. This means that if we are archiving such a
setting, we do not specify where the setting is from (an index, and
which index, or a persistent or transient cluster setting). This commit
provides such logging for the end user can better understand the
consequences of the unknown or invalid setting.

This commit fixes an issue with the configuration for the AwsSdkMetrics
logger; the issue is that the logging configuration had used underscores
instead of periods for the settings key (the perils of lenient settings
parsing).

Now index and delete methods in index shard share code for
indexing stats. This commit collapses seperate methods for
index and delete operations into a generic execute method
for performing engine write operations. As an added benefit,
this commit cleans up the interface for indexing operation
listener making it more simple and concise to use.
Currently, we treat all write operation exceptions as equals, but in reality
every write operation can cause either an environment failure (i.e. a failure
that should fail the engine e.g. data corruption, lucene tragic events) or
operation failure (i.e. a failure that is transient w.r.t the operation e.g.
parsing exception).
This change bubbles up enironment failures from the engine, after failing the
engine but captures transient operation failures as part of the operation
to be processed appopriately at the transport level.
