This change adds a special caching reader that caches all relevant
values for a range query to rewrite correctly in a can_match phase
without actually opening the underlying directory reader. This
allows frozen indices to be filtered with can_match and in-turn
searched with wildcards in a efficient way since it allows us to
exclude shards that won't match based on their date-ranges without
opening their directory readers.

* DISCOVERY: 0s Initial State Timeout in Tests
* Don't wait for initial state even with a single node, otherwise the loop writing the discovery file causes that single node to wait
for its own transport.ports file for 30s.
* Closes#35456
The ParsedReverseNested implementation should implement the ReverseNested
interface and not the Nested interface. Although this is an empty marker
interface it is confusing and can lead to casting errors. Also adding a test to
check that both ParsedNested and ParsedReverseNested implement the correct
interface.
Closes#35449
The NPE would occur if should_trim_field was overridden to
true and any field value was completely blank. This change
defends against this situation.
Fixes#35462
Some very old ancient versions of Linux do not have /etc/os-release. For
example, old Red Hat-like OS. This commit adds a fallback for handling
pretty name for these OS.
This is a follow up to #35357. That commit failed to register the new
cluster.remote.cluster_name.transport.compress setting with
`ClusterSettings`. This commit fixes that.
Before, moving to a failed step would only change the step info
to be that of the failed step. This means two things.
1. Async Steps would never be triggered to execute
2. If there are inherent problems with the action definition that can
be fixed with a policy update, these changes were not being reflected
by the new execution info.
Changes now
1. Async steps are executed after the move to the failed step in cluster state
2. the lifecycle execution info's phase definition is updated from the current
latest policy definition, even though the index isn't moving to a new phase.
Closes#35397.
Some OS (e.g., Oracle Linux Server 6.9) have a trailing space at the end
of the PRETTY_NAME line in /etc/os-release. This commit addresses this
by accounting for this trailing space when extracting the pretty name.
Given a GetTaskRequest the API returns an Optional which is empty in the case of 404s or returns a TaskInfo object if found.
Added Helper methods in RestHighLevelClient for returning empty Optionals when hitting 404s
Today it is unclear that the `storage_class` parameter to an S3 repository only
affects new objects and does not rewrite any existing objects. This commit
clarifies this point.
avoid the assertions that check the log files, because that does not work on Windows.
The rest of the test is still useful and should work on Windows CI.
Currently on Windows CI this qa module fails because there is just one test and
that test si ignored if OS is Windows.
The following "user privileges" objects have been created
on the client side:
* ApplicationResourcePrivileges
* IndicesPrivileges
* GlobalOperationPrivilege
* GlobalPrivileges
as well as the aggregating `Role` entity.
This change adds a high level freeze API that allows to mark an
index as frozen and vice versa. Indices must be closed in order to
become frozen and an open but frozen index must be closed to be
defrosted. This change also adds a index.frozen setting to
mark frozen indices and integrates the frozen engine with the
SearchOperationListener that resets and releases the directory
reader after and before search phases.

The MockTcpTransport is not friendly in regards to memory usage. It must
allocate multiple byte arrays for every message. This improves the
memory situation by failing fast if the message is improperly formatted.
Additionally, it uses reusable big arrays for at least half of the
allocated byte arrays.
Validate remote cluster license as part of put auto follow pattern api call
in addition of validation that when auto follow coordinator starts auto
following indices in the leader cluster.
Also added qa module that tests what happens to ccr after downgrading to basic license.
Existing active follow indices should remain to follow,
but the auto follow feature should not pickup new leader indices.
Add `IsNull` node in parser to simplify expressions so that `<value> IS NULL` is
no longer translated internally to `NOT(<value> IS NOT NULL)`
Replace `IsNotNullProcessor` with `CheckNullProcessor` to encapsulate both
isNull and isNotNull functionality.

* DISCOVERY: Fix RollingUpgradeTests
* Don't manually manage min master nodes if not necessary
* Remove some dead code
* Allow for manually supplying list of seed nodes
* Closes#35178
This documents how to include the search queries in the audit log.
There is a catch, that even if enabling `emit_request_body`, which should
output queries included in request bodies, search queries were not output
because, implicitly, no REST layer audit event type was included.
This folk knowledge is herein imprinted.
This change adds a logger for the query and fetch phases that prints all requests
before their execution at the trace level. This will help debugging cases where an issue
occurs during the execution since only completed queries are logged by the slow logs.
Many realm tests were written to use separate setting objects for
"global settings" and "realm settings".
Since #30241 there is no distinction between these settings, so these
tests can be cleaned up to use a single Settings object.
We changed the way realm settings are defined, and this affects custom
realms in SecurityExtensions. This change adds those details to the
breaking changes docs.

* [DOCS] ILM API Ref edits
* [DOCS] Fixed endpoint for DELETE policy.
* [DOCS] Removed comparison to setting index.lifecycle.name to null.
* [DOCS] Fixed xrefs to explain API.
Change `nullable()` logic of AND and OR to false since in the Optimizer
we cannot fold to null as we might be handling and expression in the
SELECT clause.
Introduce folding of null for AND and OR expressions in PruneFilter()
since we now know that we are in HAVING or WHERE clause and we
can fold `null` to `false`

This is related to #34483. It introduces a namespaced setting for
compression that allows users to configure compression on a per remote
cluster basis. The transport.tcp.compress remains as a fallback
setting. If transport.tcp.compress is set to true, then all requests
and responses are compressed. If it is set to false, only requests to
clusters based on the cluster.remote.cluster_name.transport.compress
setting are compressed. However, after this change regardless of any
local settings, responses will be compressed if the request that is
received was compressed.
