With this commit we add a precondition check to BulkRequest so
we fail early if users pass `null` for the request object.

Today, a race condition exists when retiring executors. Namely, if an
executor is retired and then the thread pool is terminated, the retiring
of the executor and the termination of the thread pool can race to
remove the retired executor from the queue of retired executors. More
precisely, when the executor is initially retired, it is placed on a
queue of retired executors, and then removed when it is successfully
shutdown. When the pool is terminated, it will also drain the queue of
retired executors. This leads to a time-of-check-time-of-use race where
the draining can see a retired executor on the queue but that retired
executor can be removed upon successful shutdown of that executor. This
leads to the draining attempting to remove an element from the queue
when there is none. This commit addresses this race condition by instead
safely polling the queue.

Previously multiple extensions could be provided, however, this can lead
to confusion with on-disk scripts (ie, "foo.js" and "foo.javascript")
having different content. Only a single extension is now supported.
The only language currently supporting multiple extensions was the
Javascript engine ("js" and "javascript"). It now only supports the
`.js` extension.

Currently `fuzziness` is not supported for the `cross_fields` type
of the `multi_match` query since it complicates the logic that
blends the term queries that cross_fields uses internally. At the
moment using this combination is silently ignored, which can lead to
confusions. Instead we should throw an exception in this case.
The same is true for phrase and phrase_prefix type.
Closes#7764
This commit adds a test that a fixed executors rejected count behaves as
expected. In particular, we test that if we consume the executor, then
stuff the executor queue, further tasks will be rejected and the
rejected stats are updated appropriately. This test also asserts that if
we resize the queue the rejected count is reset to zero.

This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:
```yaml
script.inline: sandbox
script.stored: sandbox
```
Instead, only a `true` or `false` value can be specified.
Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:
```yaml
script.engine.groovy.inline: true
```
Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).
Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.
Resolves#17114
Currently terms on an ip address try to put their binary representation in the
json response. With this commit, they would return a formatted ip address:
```
"buckets": [
{
"key": "192.168.1.7",
"doc_count": 1
}
]
```
We add support to explicitly exclude specific transport actions
from the request size limit check.
We also exclude the following request types currently:
*MasterPingRequest
* PingRequest
As most of our log messages are not sentences and do not end with
periods, this commit removes a period from the end of the min master
node bootstrap check log message.
Rearranges the FingerprintAnalyzer so that AsciiFolding comes earlier in the chain (after lowercasing, before stop removal, for maximum deduping power)
Closes#18266
This commit ensures that if CORS is enabled, then Origin headers are
checked regardless of whether the request came from a browser or not.
In the past, we only proceeded with CORS checks if the User-Agent was a
browser.
(same name and UUID) exists in the cluster state. This resolves a
situation where if an index data folder was copied into a node's data
directory while the node is running and that index had a tombstone in
the cluster state, the index would still get imported.

It will keep using the caching terms enum for keyword/text fields and falls back
to IndexSearcher.count for fields that do not use the inverted index for
searching (such as numbers and ip addresses). Note that this probably means that
significant terms aggregations on these fields will be less efficient than they
used to be. It should be ok under a sampler aggregation though.
This moves tests back to the state they were in before numbers started using
points, and also adds a new test that significant terms aggs fail if a field is
not indexed.
In the long term, we might want to follow the approach that Robert initially
proposed that consists in collecting all documents from the background filter in
order to compute frequencies using doc values. This would also mean that
significant terms aggregations do not require fields to be indexed anymore.
This commit modifies two logging statements in the
IndexingMemoryController to log the key for the setting
indices.memory.index_buffer_size instead of the object.

An additional sanity check introduced by #17821 makes some tests fail. This check verifies that
only one shard with same shard id is allocated to a node. This commit fixes a bug in
ClusterStateCreationUtils which would construct a cluster state that allocated two shards with same
id to the same node.
Today when join validation fails, we log a warning but do not log the
exception that led to the join validation failing. This commit modifies
this so that we do log this exception.
