Today we don't respect the indices options when they are passed
as request parameters to the `_msearch` endpoint. This is unintuitive
and doesn't cause any errors. This changes uses the top-level indices
options as the defaults for each sub search-request.
Closes#35851
More like this query allows to provide identifiers of documents to be retrieved as like/unlike items.
It can happen that at retrieval time an error is thrown, for instance caused by missing routing value when `_routing` is set required in the mapping.
Instead of ignoring such error and returning no documents for the query, the error should be re-thrown and returned to users. As part of this
change also mget and mtermvectors are unified in the way they throw such exception like it happens in other places, so that a `RoutingMissingException` is raised.
Closes#29678
This commit simplifies the throttling logic in InitialSearchPhase and removes some asserts from it. Also, a few formatting changes are applied to its code and surrounding classes.
The `wait_for_metadata_version` parameter will instruct the cluster state
api to only return a cluster state until the metadata's version is equal or
greater than the version specified in `wait_for_metadata_version`. If
the specified `wait_for_timeout` has expired then a timed out response
is returned. (a response with no cluster state and wait for timed out flag set to true)
In the case metadata's version is equal or higher than `wait_for_metadata_version`
then the api will immediately return.
This feature is useful to avoid external components from constantly
polling the cluster state to whether somethings have changed in the
cluster state's metadata.
Code that operates on-top of the engine requires all readers returned to be
unwrapped into ElasticsearchDirectoryReader. The special reader
the FrozenEngine uses wasn't wrapped.
Today when rolling a transog generation we copy the checkpoint from
`translog.ckp` to `translog-nnnn.ckp` using a simple `Files.copy()` followed by
appropriate `fsync()` calls. The copy operation is not atomic, so if we crash
at the wrong moment we can leave an incomplete checkpoint file on disk. In
practice the checkpoint is so small that it's either empty or fully written.
However, we do not correctly handle the case where it's empty when the node
restarts.
In contrast, in `recoverFromFiles()` we _do_ copy the checkpoint atomically.
This commit extracts the atomic copy operation from `recoverFromFiles()` and
re-uses it in `rollGeneration()`.
This pull request exposes two new methods in the IndexShard and
TransportReplicationAction classes in order to allow transport replication
actions to acquire all index shard operation permits for their execution.
It first adds the acquireAllPrimaryOperationPermits() and the
acquireAllReplicaOperationsPermits() methods to the IndexShard class
which allow to acquire all operations permits on a shard while exposing
a Releasable. It also refactors the TransportReplicationAction class to
expose two protected methods (acquirePrimaryOperationPermit() and
acquireReplicaOperationPermit()) that can be overridden when a transport
replication action requires the acquisition of all permits on primary and/or
replica shard during execution.
Finally, it adds a TransportReplicationAllPermitsAcquisitionTests which
illustrates how a transport replication action can grab all permits before
adding a cluster block in the cluster state, making subsequent operations
that requires a single permit to fail).

After #35332 has been merged, we noticed some test failures like #35597
in which one or more replica shards failed to be promoted as primaries
because the primary replica re-synchronization never succeed.
After some digging it appeared that the execution of the resync action was
blocked because of the presence of a global cluster block in the cluster state
(in this case, the "no master" block), making the resync action to fail when
executed on the primary.
Until #35332 such failures never happened because the
TransportResyncReplicationAction is skipping the reroute phase, the only
place where blocks were checked. Now with #35332 blocks are checked
during reroute and also during the execution of the transport replication
action on the primary. After some internal discussion, we decided that the TransportResyncReplicationAction should never be blocked. This action is
part of the replica to primary promotion and makes sure that replicas are in
sync and should not be blocked when the cluster state has no master or
when the index is read only.
This commit changes the TransportResyncReplicationAction to make obvious
that it does not honor blocks. It also adds a simple test that fails if the resync
action is blocked during the primary action execution.
Closes#35597
Adds an XContent sub parser class that can to wrap another
XContent parser at the beginning of an object and allow skiping
all children in case of the parsing failure. It also uses this
subparser to ignore the rest of the GeoJson shape if the
parsing fails and we need to ignore the geoshape due to the
ignore_malformed flag.

* [GEO] Add support to ShapeBuilders for building Lucene geometry
This commit adds support for building lucene geometry from the ShapeBuilders.
This is needed for integrating LatLonShape as the primary indexing approach
for geo_shape field types. All unit and integration tests are updated to
add randomization for testing both jts/s4j shapes and lucene shapes.
Queries across multiple fields generate MatchNoDocsQuerys for fields that are
unmapped. In certain situation this can lead to erroneous behaviour,
for example when an umapped field is used in a query_string query across
several fields. If some of the tokens in the query string get eliminated by an
analyzer on the mapped fields, the same token will currently generate
MatchNoDocsQuerys combined into a disjunction, which in turn
leads to no matches in the overall query. Instead we should simply not add
MatchNoDocsQuerys to those disjunctions.
Closes#34708
This parameter in the `query_string` query was deprecated in 6.0 and ignored
since then. Its API methods and remaining uses can be removed in the upcoming
major version.

This commit adds a rest endpoint for freezing and unfreezing an index.
Among other cleanups mainly fixing an issue accessing package private APIs
from a plugin that got caught by integration tests this change also adds
documentation for frozen indices.
Note: frozen indices are marked as `beta` and available as a basic feature.

* Add tests for types deprecation in the _search endpoint.
This change fixes#35351. Users were no longer able to return types of numbers other than doubles for bucket aggregation scripts. This change reverts to the previous behavior of being able to return any type of number and having it converted to a double outside of the script.
This inserts newlines in order to reduce line lengths in the
o.e.action.admin.cluster package to 140 characters or less. This
also remves the checkstyle suppressions for affected files.

The javadocs of the CharSequence interface state that not all of its
implementations define the general contracts of the Object#equals and
Object#hashCode methods, therefore it is dangerous to use different CharSequence
instances as elements in a set or as keys in a map. While we probably mostly use
Strings in sets, in some places this is not enforced. To prevent this from
accidentally happening, this change replaces all occurances of Set<CharSequence>
which are currently mostly used in the completion suggester code with the more
concrete usage of Set<String>.
