* Enhance TimeValue.toString() to allow specifying fractional values.
This enhances the `TimeValue` class to allow specifying the number of
truncated fractional decimals when calling `toString()`. The default
remains 1, however, more (or less, such as 0) can be specified to change
the output.
This commit also re-organizes some things in `TimeValue` such as putting
all the class variables near the top of the class, and moving the
constructors to the first methods in the class, in order to follow the
structure of our other code.
* Rename `toString(...)` to `toHumanReadableString(...)`
Fsyncing directories on Windows is not possible. We always suppressed
this by allowing that an AccessDeniedException is thrown when attemping
to open the directory for reading. Yet, this suppression also allowed
other IOExceptions to be suppressed, and that was a bug (e.g., the
directory not existing, or a filesystem error and reasons that we might
get an access denied there, like genuine permissions issues). This
leniency was previously removed yet it exposed that we were suppressing
this case on Windows. Rather than relying on exceptions for flow control
and continuing to suppress there, we simply return early if attempting
to fsync a directory on Windows (we will not put this burden on the
caller).
Today in the method IOUtils#fsync we ignore IOExceptions when fsyncing a
directory. However, the catch block here is too broad, for example it
would be ignoring IOExceptions when we try to open a non-existant
file. This commit addresses that by scoping the ignored exceptions only
to the invocation of FileChannel#force.
hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

* Fix forking JVM runner
* Don't bump shadow plugin version
This change adds a `frozen` engine that allows lazily open a directory reader
on a read-only shard. The engine wraps general purpose searchers in a LazyDirectoryReader
that also allows to release and reset the underlying index readers after any and before
secondary search phases.
Relates to #34352
The testCharsBeginsWith test has a check that a random prefix of length
2 is not the prefix of a char[]. However, there is no check that the
char[] is not randomly generated with the same two characters as the
prefix. This change ensures that the char[] does not begin with the
prefix.
Closes#34765
This change adds a `_source` only snapshot repository that allows to wrap
any existing repository as a _backend_ to snapshot only the `_source` part
including live docs markers. Snapshots taken with the `source` repository
won't include any indices, doc-values or points. The snapshot will be reduced in size and
functionality such that it requires full re-indexing after it's successfully restored.
The restore process will copy the `_source` data locally starts a special shard and engine
to allow `match_all` scrolls and searches. Any other query, or get call will fail with and unsupported operation exception. The restored index is also marked as read-only.
This feature aims mainly for disaster recovery use-cases where snapshot size is
a concern or where time to restore is less of an issue.
**NOTE**: The snapshot produced by this repository is still a valid lucene index. This change doesn't allow for any longer retention policies which is out of scope for this change.
This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
