This commit creates a keystore and adds settings to it during the
cluster formation for integration tests. Users can define a
`keyStoreSetting` in build files for settings that need to be placed in
the keystore.
MapperService#parentTypes is rewrapped in an UnmodifiableSet in MapperService#internalMerge every time the cluster state is updated. After thousands of updates the collection is wrapped so deeply that calling a method on it generates a StackOverflowError.

When adding filesystem stats from individual filesystems, free and
available can overflow. This commit guards against this by adjusting
these situations to Long.MAX_VALUE.

This commit marks the EvilJNANativesTests as awaiting fixes due to these
tests failing on platforms that do not provide at least version 2.14 of
glibc.
Currently the task manager is tied to the transport and can only create tasks based on TransportRequests. This commit enables task manager to support tasks created by non-transport services such as the persistent tasks service.
* Add support for fragment_length in the unified highlighter
This commit introduce a new break iterator (a BoundedBreakIterator) designed for the unified highlighter
that is able to limit the size of fragments produced by generic break iterator like `sentence`.
The `unified` highlighter now supports `boundary_scanner` which can `words` or `sentence`.
The `sentence` mode will use the bounded break iterator in order to limit the size of the sentence to `fragment_length`.
When sentences bigger than `fragment_length` are produced, this mode will break the sentence at the next word boundary **after**
`fragment_length` is reached.
This commit changes the method for checking the interrupt status of a
thread that is intentionally interrupted during
AdapterActionFutureTests#testInteruption. Namely, we want to check and
clear the interrupt status before joining on the interrupting thread. If
we do not clear the status, when we lose a race where the interrupting
thread is not yet finished, an interrupted exception will be thrown when
we try to join on it. Clearing the interrupted status on the main thread
addresses this issue.
This commit moves the checkstyle rule of max line length from 140
characters to 100 characters. We whitelist all existing violations and
will address them in follow-ups.

In Gradle 3.4, the buildSrc plugin seems to be packaged into a jar before it is accessed by the rest of the build and the signatures file for the third-party audit task cannot be accessed as
getClass().getResource('/forbidden/third-party-audit.txt') then points to a file entry in a JAR, which cannot be loaded directly as a File object. This commit changes the third-party audit task to pass the content of the signatures file as a String instead.
When a thread blocking on an adapter action future is interrupted, we
throw an illegal state exception. This is documented, but it is rude to
not restore the interrupt flag. This commit restores the interrupt flag
in this situation, and adds a test.

The reindex API is mature now, and we will work to maintain backwards
compatibility in accordance with our backwards compatibility
policy. This commit unmarks the reindex API as experimental.

In cases where the user specifies only the `text` option on the top level
suggest element (either via REST or the java api), this gets transferred to the
`text` property in the SuggestionSearchContext. CompletionSuggestionContext
currently requires prefix or regex to be specified, otherwise errors. We should
use the global `text` property as a fallback if neither prefix nor regex is provided.

In SI units, "kilobyte" or "kB" would mean 1000 bytes, whereas "KiB" is
used for 1024. Add a note in `api-conventions.asciidoc` to clarify the
meaning in Elasticsearch.
In this repository, `Settings.builder` is used everywhere although it does exactly same as `Settings.settingsBuilder`. With the reference of the commit 42526ac28e , I think mistakenly this `Settings.settingsBuilder` remains in.
This fixes an NPE in finding scaled float stats. The type of min/max
methods on the wrapped long stats returns a boxed type, but in the case
this is null, the unbox done for the FieldStats.Double ctor primitive
types will cause the NPE. These methods would have null for min/max when
the field exists, but does not actually have points values.

This commit adds a system property that enables end-users to explicitly
enforce the bootstrap checks, independently of the binding of the
transport protocol. This can be useful for single-node production
systems that do not bind the transport protocol (and thus the bootstrap
checks would not be enforced).

This change adds a new method that returns the underlying char[] of a SecureString and the ability
to clone the SecureString so that the original SecureString is not vulnerable to modification.
Closing the cloned SecureString will wipe the char[] that backs the clone but the original SecureString remains unaffected.
Additionally, while making a separate change I found that SecureSettings will fail when diff is called on them and there
is no fallback setting. Given the idea behind SecureSetting, I think that diff should just be a no-op and I have
implemented this here as well.
Currently GeoHashGridAggregatorTests#testWithSeveralDocs increases the expected
document count per hash for each geo point added to a document. When points
added to the same doc fall into one bucket (one hash cell) the document should
only be counted once.

While trying to improve the failure output in #23547, the stderr was
also captured from jrunscript. This was under the assumption that stderr
is only written to in case of an error. However, with java 9, when
JAVA_TOOL_OPTIONS are set, they are output to stderr. And our CI sets
JAVA_TOOL_OPTIONS for some reason. This commit fixes the jrunscript call
to use a separate buffer for stderr.
A previous change to the multi-search request execution to avoid stack
overflows regressed on limiting the number of concurrent search requests
from a batched multi-search request. In particular, the replacement of
the tail-recursive call with a loop could asynchronously fire off all of
the remaining search requests in the batch while max concurrent search
requests are already executing. This commit attempts to address this
issue by taking a more careful approach to the initial problem of
recurisve calls. The cause of the initial problem was due to possibility
of individual requests completing on the same thread as invoked the
search action execution. This can happen, for example, in cases when an
individual request does not resolve to any shards. To address this
problem, when an individual request completes we check if it completed
on the same thread as fired off the request. In this case, we loop and
otherwise safely recurse. Sadly, there was a unit test to check that the
maximum number of concurrent search requests was not exceeded, but that
test was broken while modifying the test to reproduce a case that led to
the possibility of stack overflow. As such, we randomize whether or not
search actions execute on the same thread as the thread that invoked the
action.

This commit improves the output when jrunscript fails to include the
full output of the command. It also makes the quoting that is needed for
windows only happen on windows (which worked on java 8, but for some
reason does not work with java 9)
When plugins are installed on a union filesystem (for example, inside a
Docker container), removing them can fail because we attempt an atomic
move which will not work if the plugin is not installed in the top
layer. This commit modifies removing a plugin to fall back to a
non-atomic move in cases when the underlying filesystem does not support
atomic moves.

This commit upgrades the Netty dependencies from version 4.1.8 to
version 4.1.9. This commit picks up a few bug fixes that impacted us:
- Netty was incorrectly ignoring interfaces with self-assigned MAC
addresses (e.g., instances running in Docker containers or on EC2)
- incorrect handling of the Expect: 100-continue header
Relates #23540
With this commit we change the default receive predictor size for Netty
from 32kB to 64kB as our testing has shown that this leads to less
allocations on smaller heaps like the default out of the box
configuration and this value also works reasonably well for larger
heaps.
