If creating the REST request throws an exception (for example, because
of invalid headers), we leak the request due to failure to release the
buffer (which would otherwise happen after replying on the
channel). This commit addresses this leak by handling the failure case.

The uid bytes (as the type#id) were needlessly being created even though
they are no longer needed after the move to single type per index. This
commit avoids creating these when parsed documents are constructed.

We do some accounting in IndexShard that is not necessarily correct since
we maintain two different index readers. This change moves the accounting under
the engine which knows what reader we are refreshing.

This local checkpoint tracker uses collections of bit sets to track
which sequence numbers are complete, eventually removing these bit sets
when the local checkpoint advances. However, these bit sets were eagerly
allocated so that if a sequence number far ahead of the checkpoint was
marked as completed, all bit sets between the "last" bit set and the bit
set needed to track the marked sequence number were allocated. If this
sequence number was too far ahead, the memory requirements could be
excessive. This commit opts for a different strategy for holding on to
these bit sets and enables them to be lazily allocated.

We added an index-level setting for controlling the size of the bit sets
used to back the local checkpoint tracker. This setting is really only
needed to control the memory footprint of the bit sets but we do not
think this setting is going to be needed. This commit removes this
setting before it is released to the wild after which we would have to
worry about BWC implications.

When partitioning version constants into released and unreleased
versions, today we have a bug in finding the last unreleased
version. Namely, consider the following version constants on the 6.x
branch: ..., 5.6.3, 5.6.4, 6.0.0-alpha1, ..., 6.0.0-rc1, 6.0.0-rc2,
6.0.0, 6.1.0. In this case, our convention dictates that: 5.6.4, 6.0.0,
and 6.1.0 are unreleased. Today we correctly detect that 6.0.0 and 6.1.0
are unreleased, and then we say the previous patch version is unreleased
too. The problem is the logic to remove that previous patch version is
broken, it does not skip alphas/betas/RCs which have been released. This
commit fixes this by skipping backwards over pre-release versions when
finding the previous patch version to remove.

* Enhances exists queries to reduce need for `_field_names`
Before this change we wrote the name all the fields in a document to a `_field_names` field and then implemented exists queries as a term query on this field. The problem with this approach is that it bloats the index and also affects indexing performance.
This change adds a new method `existsQuery()` to `MappedFieldType` which is implemented by each sub-class. For most field types if doc values are available a `DocValuesFieldExistsQuery` is used, falling back to using `_field_names` if doc values are disabled. Note that only fields where no doc values are available are written to `_field_names`.
Closes#26770
* Addresses review comments
* Addresses more review comments
* implements existsQuery explicitly on every mapper
* Reinstates ability to perform term query on `_field_names`
* Added bwc depending on index created version
* Review Comments
* Skips tests that are not supported in 6.1.0
These values will need to be changed after backporting this PR to 6.x
This query returns documents that match with at least one ore more
of the provided terms. The number of terms that must match varies
per document and is either controlled by a minimum should match
field or computed per document in a minimum should match script.
Closes#26915
Update API, Cluster Update Settings API and Put Index Template API didn't have the request body set to required in their spec, hence this commit updates the spec to align them with reality.
* Update Docker docs for 6.0.0-rc2
* Update the docs to match the new Docker "image flavours" of "basic",
"platinum", and "oss".
* Clarifications for Openshift and bind-mounts
* Bump docker-compose 2.x format to 2.2
* Combine Docker Toolbox instructions for setting vm.max_map_count for
both macOS + Windows
* devicemapper is not the default storage driver any more on RHEL
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.
Relates #27082
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.
