Currently when failing a shard we also mark it as stale (eg. remove its
allocationId from from the InSync set). However in some cases, we need
to be able to fail shards but keep them InSync set. This commit adds
such capacity. This is a preparatory change to make the primary-replica
resync less lenient.

Gradle 4.5 now hides immutable task dependencies. We previously copied
the existing dependencies from the builtin test task to the
randomizedtesting task. This commit adds testClasses as an extra
dependency of the randomizedtesting task, to ensure the classes are
built.
ava.time has the functionality needed to deal with timezones with varying
offsets correctly, but it also has a bunch of methods that silently let you
forget about the hard cases, which raises the risk that we'll quietly do the
wrong thing at some point in the future.
This change adds the trappy methods to the list of forbidden methods to try and
help stop this from happening.
It also fixes the only use of these methods in the codebase so far:
IngestDocument#deepCopy() used ZonedDateTime.of() which may alter the offset of
the given time in cases where the offset is ambiguous.
This commit switches all the modules and server test code to use the
non-deprecated `ParseField.match` method, passing in the parser's deprecation
handler or the logging deprecation handler when a parser is not available (like
in tests).

Today the correctness of synced-flush is guaranteed by ensuring that
there is no ongoing indexing operations on the primary. Unfortunately, a
replica might fall out of sync with the primary even the condition is
met. Moreover, if synced-flush mistakenly issues a sync_id for an out of
sync replica, then that replica would not be able to recover from the
primary. ES prevents that peer-recovery because it detects that both
indexes from primary and replica were sealed with the same sync_id but
have a different content. This commit modifies the synced-flush to not
issue sync_id for out of sync replicas. This change will report the
divergence issue earlier to users and also prevent replicas from getting
into the "unrecoverable" state.

We do want to keep this functionality in the future and we provide support for it.
This change is a first step towards replacing the `synonym` token filter with `synonym_graph`.
The primary currently replicates writes to all other shard copies as soon as they're added to the routing table. Initially those shards are not even ready yet to receive these replication requests, for example when undergoing a file-based peer recovery. Based on the specific stage that the shard copies are in, they will throw different kinds of exceptions when they receive the replication requests. The primary then ignores responses from shards that match certain exception types. With this mechanism it's not possible for a primary to distinguish between a situation where a replication target shard is not allocated and ready yet to receive requests and a situation where the shard was successfully allocated and active but subsequently failed.
This commit changes replication so that only initializing shards that have successfully opened their engine are used as replication targets. This removes the need to replicate requests to initializing shards that are not even ready yet to receive those requests. This saves on network bandwidth and enables features that rely on the distinction between a "not-yet-ready" shard and a failed shard.
Currently the callouts for this section are below all the examples, making it
harder to relate them to the snippets. Instead they should be moved closer
to the examples.
* [DOCS] expand examples on providing mappings for create index and put mapping
The create index API and put mappings API docs the for high-level Java REST client didn't have a lot of info on how to provide mappings. This commit adds some examples.
This assertion does not hold if engine is flushed between the invocation
of translog.uncommittedSizeInBytes and translog.uncommittedOperations.
These two values can be calculated from different commits.
If the translog flush threshold is too small (eg. smaller than the
translog header), we may repeatedly flush even there is no uncommitted
operation because the shouldFlush condition can still be true after
flushing. This is currently avoided by adding an extra guard against the
uncommitted operations. However, this extra guard makes the shouldFlush
complicated. This commit replaces that extra guard by a lower bound for
translog flush threshold. We keep the lower bound small for convenience
in testing.

This commit splits the async execution documentation into 2 parts, one
for the async method itself and one for the action listener. This allows
to add more doc and to use CountDownLatches in doc tests to wait for
asynchronous operations to be completed before moving to the next test.
It also renames few files.
Related to #28457
Similarly to other documentation tests in the high level client, the
asynchronous operation like update, index or delete can make the test
fail if it sneak in between the middle of another operation.
This commit moves the async doc tests to be the last ones executed and
adds assert busy loops to ensure that the asynchronous operations are
correctly terminated.

Persistent tasks are build on top of node tasks and provide functionality to restart a task to run on a different coordination node in case the coordinating node is no longer available.
It is up to a persistent task implementation to keep track of status, so that in case the task is restarted, the task can continue were it left off before it was restarted.
This change remove the `CircuitBreakerIT. testParentChecking` test method which fails intermittently in unexpected ways with a `MemoryCircuitBreakerTests. testBorrowingSiblingBreakerMemory` unit test method which can test the borrowing functionality more directly
Closes#28223
This change adds a shallow copy method for aggregation builders. This method returns a copy of the builder replacing the factoriesBuilder and metaDada
This method is used when the builder is rewritten (AggregationBuilder#rewrite) in order to make sure that we create a new instance of the parent builder when sub aggregations are rewritten.

This change fixes a possible AIOOB during the parsing of the document that contains the indexed shape.
This change ensures that the parsing does not continue when the field that contains the shape has been found.

These tests were disabled to facilitate backport of a PR which is not
yet complete. These tests were accidentally reenabled after a merge
conflict was resolved in the wrong direction. This commit addresses this
issue.
Today a SecureSM security manager allows defining a list of packages
that can exit the VM. However, today there are no restrictions on
defining a package inside another JAR. This commit strengthens the
ability to prevent exit by allowing construction of SecureSM to be done
with a list of regular expressions (instead of a list of prefix names)
that classes will be tested against. With this, a security manager can
be installed that permits only exiting from an exact list of classes.
Relates #5
Today, SecureSM has a mechanism that enables a hardcoded list of test
packages to exit if the SecureSM instance is constructed with a boolean
flag indicating that these packages will be permitted to exit. This
commit replaces this mechanism by allowing the SecureSM instance to be
constructed with a whitelist of packages that can exit.
Relates #4
This commit adds an assertion to the TestSecureSM#testNoModifySibling
test that sanity checks that the second child was actually interrupted
and therefore actually attempted to interrupt the first child.
Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
Sometimes, in some places, the clocks are set back across midnight, leading to
overlapping days. This was not handled as expected, and this change fixes this.
Additionally, in this situation it is not true that rounding a time down to the
nearest day is a monotonic operation, as asserted in these tests. This change
suppresses those assertions in those rare cases.
Fixes#27966.
