Do not filter by tiebreaker while searching sequence matches as
it's not monotonic and thus can filter out valid data.
Add handling for data 'near' the boundary that has the same timestamp
but different tie-breaker and thus can be just outside the window.

#63214 made TypeFieldType a constant field, and fixed things so that it always
emits deprecation warnings whenever it is referenced in a query or aggregation.
However, it also emits warnings when it is used to build a type filter through
the search context; this is unnecessary, as warnings are already emitted by
the REST layer when types are specified as part of the URL, and it is causing
failures in some BWC tests.
This commit adds a specialised typeFilter method to TypeFieldType to handle
this case without emitted any extra warnings. It also removes an unused duplicate
TypeFieldType class that resulted from a backport merge error.
Fixes#63366
As a result of this, we can remove a chunk of code from TypeParsers as well. Tests
for search/index mode analyzers have moved into their own file. This commit also
rationalises the serialization checks for parameters into a single SerializerCheck
interface that takes the values includeDefaults, isConfigured and the value
itself.

We were not consistent in checking for node roles before adding listeners.
In some cases we did check the necessity of a CS listener and in others we did not.
This commit fixes a number of cases of redundant listeners that don't apply to all node roles.
In #61906 we agreed on always providing the default value
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE
when the SnasphotInfoService failed to retrieve the exact
size for a given snapshot shard. The motivation was to
allow the shard allocation to move forward in case of
failures (so that the unassigned shard does not get stuck
in an unassigned state for too long) while relying on the
fallback values for shard sizes.
Sadly a bug in the
SnapshotShardSizeInfo#getShardSize(ShardRouting, long)
makes the default value to be ignored when the snapshot
shard size retrieval previously failed, returning
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE
instead of the provided default value. With DiskThresholdDecider
also not relying on the provided default value this triggers
some assertion like in #63376 which helped us to spot the bug.
Closes ##63376
The first refreshDiskUsage() refreshes the ClusterInfo update which in turn
calls listeners like DiskThreshMonitor. This one triggers a reroute as
expected and turns an internal checkInProgress flag before submitting
a cluster state update to relocate shards (the internal flag is toggled
again once the cluster state update is processed).
In the test I suspect that the second refreshDiskUsage() may complete
before DiskThreshMonitor's internal flag is set back to its initial state,
resulting in the second ClusterInfo update to be ignored and message
like "[node_t0] skipping monitor as a check is already in progress" to
be logged. Adding another wait for languid events to be processed
before executing the second refreshDiskUsage() should help here.
Closes#62326
This change adds configurable settings to the `CustomRealm` in the QA
project as the correct declaration and use of settings can be a source
of confusion in custom realms.
The "username" "password" and "roles" are now all configurable, which
demonstrates the use of a simple string setting ("username") a secure
setting ("password") and a more complex list setting ("roles").
Backport of: #62287
Strings in the watcher context may use the `.sha1()` and `.sha256()`
augmentation added for ingest.

Currently we add translog operation bytes to an array list and flush
them on the next write. Unfortunately, this does not currently play well
with our byte pooling which means each operation is backed, at minimum,
by a 16KB array. This commit improves memory efficiency for small
operations by serializing the operations to an output stream.
This PR updates the `logstash_admin` role to include the recently-added Logstash Pipeline Management APIs, as well as access to the `.logstash*` index pattern.

Currently a TranslogWriter add operation is synchronized. This operation
adds the bytes to the file output stream buffer and issues a write
system call if the buffer is filled. This happens every 8KB which means
that we routinely block other add calls on system writes.
This commit modifies the add operation to simply place the operation in
an array list. The array list if flushed when the sync call occurs or
when 1MB is buffered.
The ML cpp notice only exists with default distributions, but the check
task exists on all archive distributions. This commit avoids creating
the task for distributions that don't have ML.

Plugins are loaded in isolated child class loaders of the root class loader. However, some libraries depend on the context class loader being set. This commit sets the context class loader for the duration of calling each plugins constructor.

When constructing a value fetcher, the 'parsesArrayValue' flag must match
`FieldMapper#parsesArrayValue`. However there is nothing in code or tests to
help enforce this.
This PR reworks the value fetcher constructors so that `parsesArrayValue` is
'false' by default. Just as for `FieldMapper#parsesArrayValue`, field types must
explicitly set it to true and ensure the behavior is covered by tests.
Follow-up to #62974.
An invalid void expression type from a null safe operator caused ClassFormatError for the script Map
x= ['0': 0]; x?.0 > 1. This change sets and propagates the correct expression type for the null safe
operator to be written out.
This PR adds deprecation warnings when accessing System Indices via the REST layer. At this time, these warnings are only enabled for Snapshot builds by default, to allow projects external to Elasticsearch additional time to adjust their access patterns.
Deprecation warnings will be triggered by all REST requests which access registered System Indices, except for purpose-specific APIs which access System Indices as an implementation detail a few specific APIs which will continue to allow access to system indices by default:
- `GET _cluster/health`
- `GET {index}/_recovery`
- `GET _cluster/allocation/explain`
- `GET _cluster/state`
- `POST _cluster/reroute`
- `GET {index}/_stats`
- `GET {index}/_segments`
- `GET {index}/_shard_stores`
- `GET _cat/[indices,aliases,health,recovery,shards,segments]`
Deprecation warnings for accessing system indices take the form:
```
this request accesses system indices: [.some_system_index], but in a future major version, direct access to system indices will be prevented by default
```

Determines the shard size of shards before allocating shards that are
recovering from snapshots. It ensures during shard allocation that the
target node that is selected as recovery target will have enough free
disk space for the recovery event. This applies to regular restores,
CCR bootstrap from remote, as well as mounting searchable snapshots.
The InternalSnapshotInfoService is responsible for fetching snapshot
shard sizes from repositories. It provides a getShardSize() method
to other components of the system that can be used to retrieve the
latest known shard size. If the latest snapshot shard size retrieval
failed, the getShardSize() returns
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE. While
we'd like a better way to handle such failures, returning this value
allows to keep the existing behavior for now.
Note that this PR does not address an issues (we already have today)
where a replica is being allocated without knowing how much disk
space is being used by the primary.
