It is required in order to work correctly with bulk scorer implementations
that change the scorer during the collection process. Otherwise sub collectors
might call `Scorer.score()` on the wrong scorer.
Closes#27131
This commit is a minor refactoring of internal engine to move hooks for
generating sequence numbers into the engine itself. As such, we refactor
tests that relied on this hook to use the new hook, and remove the hook
from the sequence number service itself.

This change is required in order to support a size based check for the
index rollover.
The index size is estimated by sampling the existing segments only. We
prefer using segments to StoreStats because StoreStats is not reliable
if indexing or merging operations are in progress.

Currently, when we create a BeiderMorseFilter with an unspecified `languageset`,
the filter will not guess the language, which should be the default behaviour.
This change fixes this and adds a simple test for the cases with and without
provided `languageset` settings.
Closes#26771
This change makes sure that we track score when sort is set to relevancy only.
In this case we always track max score like normal search does.
Closes#23840
* Apply missing request options to the expand phase
This change adds some missing options to the expand query that builds the inner hits for field collapsing.
The following options are now applied to the inner_hits query:
* post_filters
* preferences
* routing

The new discovery stats were pushed to the 6.x branch (currently
versioned at 6.1.0) but master was not updated to reflect this. This
impacts the mixed-cluster BWC tests because a 6.1.0 node will be trying
to send a 7.0.0 node the new discovery stats but the 7.0.0 did not yet
understand that it should be reading these when talking to a 6.1.0
node. This commit addresses this, and changes the skip version on the
discovery stats REST tests.
Windows handles trying to read a file that does not exist because a
component of the path is not a directory differently than other OS
handle this situation. This commit adjusts these assertions for Windows.
When executing a cluster settings update that leaves the cluster state
unchanged, we skip validation and this avoids deprecation logging for
deprecated settings in the cluster state. This commit addresses this by
running validation even if the settings are unchanged.

When a search is executing locally over many shards, we can stack
overflow during query phase execution. This happens due to callbacks
that occur after a phase completes for a shard and we move to the same
phase on another shard. If all the shards for the query are local to the
local node then we will never go async and these callbacks will end up
as recursive calls. With sufficiently many shards, this will end up as a
stack overflow. This commit addresses this by truncating the stack by
forking to another thread on the executor for the phase.

The headers passed to reindex were skipped except for the last one. This
commit fixes the copying of the headers, as well as adds a base test
case for rest client builders to access the headers within the built
rest client.

Till now the yaml test runner was verifying that the provided path parts and parameters are supported.
With this PR, yaml test runner also checks that all required path parts and parameters are provided.
Finder creates these files if you browse a directory there. These files
are really annoying, but it's an incredible pain for users that these
files are created unbeknownst to them, and then they get in the way of
Elasticsearch starting. This commit adds leniency on macOS only to skip
these files.

This commit adjusts the format of the SHA-512 checksum files supported
by the plugin installer. In particular, we now require that the SHA-512
format be a single-line file containing the checksum followed by two
spaces followed by the filename. We continue to support the legacy
format for SHA-1.

Turns out that `ShardSearchTarget` is nullable, hence its fields may not be printed out as part of `ShardSearchFailure#toXContent`, in which case `fromXContent` cannot parse it back. We would previously try to create the object with all of its fields set to null, but `Index` complains about it in the constructor. Also made sure that this code path is covered by our unit tests in `ShardSearchFailureTests`.
Closes#27055
Introduce minimal thread scheduler as a base class for `ThreadPool`. Such a class can be used from the `BulkProcessor` to schedule retries and the flush task. This allows to remove the `ThreadPool` dependency from `BulkProcessor`, which requires to provide settings that contain `node.name` and also needed log4j for logging. Instead, it needs now a `Scheduler` that is much lighter and gets automatically created and shut down on close.
Closes#26028
It's believed that using diffs obsoletes the other mechanism for reusing the
bits of the ClusterState that didn't change between updates, but in fact we
don't know for sure how often the diff mechanism works successfully. The stats
collected here will tell us.
Right now if the number of shards for a particular index is equal across the
data paths, we tie-break on space. This changes to tie-break first on the total
number of shards for each path, and then, if that is the same, on the usable
bytes.

If timed runnable wraps an abstract runnable, then it should delegate to
the abstract runnable otherwise force execution and handling rejections
is dropped on the floor. Thus, timed runnable should itself be an
abstract runnable delegating all methods to the wrapped runnable in
cases when it is an abstract runnable. This commit causes this to be the
case.
