* Move all zen discovery classes into o.e.discovery.zen
This collapses sub packages of zen into zen. These all had just a couple
classes each, and there is really no reason to have the subpackages.
* fix checkstyle
Date math index/alias expressions in mget will now be resolved to a concrete single index instead of failing the mget item with an `IndexNotFoundException`.
Added also an integration test to verify multi index aliases do not fail the entire mget request.
Closes#17957
This commit removes an undocumented output parameter node_info_format
from the cluster stats and node stats APIs. Currently the parameter does
not even work as it is not whitelisted as an output parameter. Since
this parameter is not documented, we opt to just remove it.
Relates #21021
When indices stats are requested via the node stats API, there is a
level parameter to request stats at the index, node, or shards
level. This parameter was not whitelisted when URL parsing was made
strict. This commit whitelists this parameter.
Additionally, there was some leniency in the parsing of this parameter
that has been removed.

This change makes the ElectMasterService local to ZenDiscovery, no
longer created by guice, and thus also removes the ability for plugins
to customize. This extension point is no longer used by anything.
This was an error-prone version type that allowed overriding previous
version semantics. It could cause primaries and replicas to be out of
sync however, so it has been removed.
This is related to #20377, which removed the feature entirely. This
allows operations to continue to use the `force` version type if the
index was created before 6.0, in the event a document using it exists in
a translog being replayed.
Previous to this change any request using a script sort in a top_hits
aggregation would fail because the compilation of the script happened
after the QueryShardContext was frozen (after we had worked out if the
request is cachable).
This change moves the calling of build() on the SortBuilder to the
TopHitsAggregationBuilder which means that the script in the script_sort
will be compiled before we decide whether to cache the request and freeze
the context.
Closes#21022
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.
closes#20949
* 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.
