Watcher still exposes some dates as joda DateTime objects. This commit
adds back joda to the painless whitelist so they can still be accessed.

This commit adds back bundling of all deps of the sql jdbc jar. This was
lost in a refactoring of how the shadow plugin is handled for the entire
elasticsearch project.
This removes the option to run a cluster without enforcing the
cluster-wide shard limit, making strict enforcement the default and only
behavior. The limit can still be adjusted as desired using the cluster
settings API.
This commit adds the support for exists query in the sorted execution mode
of the `composite` aggregation. We'll execute the aggregation from the sorted
points and use early termination if the main query is an `exists` query over the
first source of the `composite` aggregation.
Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN)
functions which are in the family of CONDITIONAL functions.
Implementation follows PostgreSQL behaviour, so the functions return
`NULL` when all of their arguments evaluate to `NULL`.
Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and
`ConditionalProcessor` respectively, to be able to reuse them for
`Greatest` and `Least` evaluations. To achieve that `ConditionalOperation`
has been added to differentiate between the functionalities at execution
time.

Due to some unresolvable type conflict between the expected definition
in JDBC vs ODBC, the driver mode is now passed over so that certain
command can change their results accordingly (in this case SYS COLUMNS)
Fix#35376
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
This operator handles nulls in different way than the normal `=`.
If one of the operants is `null` and the other not it returns `false`.
If both operants are `null` it returns `true`. Therefore in contrary to
`=`, which returns `null` if at least one of the operants is `null`, this one
never returns `null` as a result.

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).

We didn't check that the ExplainLifecycleRequest was constructed with at least
one index before, now that we do we must also make sure the tests
mutateInstance() method used in equals/hashCode checks doesn't accidentally
create an empty index array.
