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.

This endpoint was not previously documented as it was not
particularly useful to end users. However, since the HLRC
will support the endpoint we need some documentation to
link to.
The purpose of the endpoint is to provide defaults and
limits used by ML. These are needed to fully understand
configurations that have missing values because the missing
value means the default should be used.

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
This commit moves the documentation and examples for the `index_prefixes`
option on text fields to its own file, to bring it in line with other mapping
parameters, and expands a bit on both.
`testIncompatibleDiffResendsFullState` sometimes makes a 2-node cluster and
then partitions one of the nodes from the leader, which makes the leader stand
down. Then when the partition is removed the cluster re-forms but does so by
sending full cluster states, not diffs, causing the test to fail.
Additionally `testDiffBasedPublishing` sometimes fails if a publication is
delivered out-of-order, wiping out a fresher last-received cluster state with a
less-fresh one. This is fixed here by passing the received cluster state to the
coordinator before recording it as the last-received one, relying on the
coordinator's freshness checks.
When there is no persistent tasks metadata we could hit a null pointer
exception when executing a follower stats request. This is because we
inspect the persistent tasks metadata. Yet, if no tasks have been
registered, this is null (as opposed to empty). We need to avoid
de-referencing the persistent tasks metadata in this case. That is what
this commit does, and we add a test for this situation.
By setting the cron to 2017, we ensure it won't trigger. This makes it
easier to test because we know the job will _only_ be in STARTED,
and we can ignore INDEXING states due to transient triggers.
Closes#35779
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.

Previously, it was possible to initialize a request
that does not include any indices. This results in undefined
behavior when generating the URL path to send to ES. By
enforcing indices to be defined, users will be more explicit
about the intention.
* [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.
This test is failing sometimes with Zen2 due to the lack of lag detection.
Zen1 does not have this problem as it only considers a join as valid if the
corresponding cluster state update is successfully published and committed
on the joining node.
Today we have a way to atomically persist global MetaData and
IndexMetaData to disk when new ClusterState is received. All other
ClusterState fields are not persisted.
However, there are other parts of ClusterState that should be
persisted, namely:
version
term
lastCommittedConfiguration
lastAcceptedConfiguration
votingTombstones
version is changed frequently, other fields are not. We decided
to group term, lastCommittedConfiguration,
lastAcceptedConfiguration and votingTombstones into
CoordinationMetaData class and make CoordinationMetaData a field
inside MetaData.
MetaData.toXContent and MetaData.fromXContent should take care of
CoordinationMetaData.
version stays as a top level field in ClusterState and will be
persisted as part of Manifest in a follow-up commit.
Also MetaData.isGlobalStateEquals should be extended to include
coordinationMetaData in comparison.
This commit favors exposing getters, such as getTerm directly in
ClusterState to avoid massive code changes.
An example of CoordinationMetaState.toXContent:
{
"term": 1,
"last_committed_config": [
"TiIuBcbBtpuXyDDVHXeD",
"ZIAoVbkjjLPLUuYLaTkw"
],
"last_accepted_config": [
"OwkXbXZNOZPJqccdFHdz",
"LouzsGYwmQzpeQMrboZe",
"fCKGRZdjLTqzXAqPUtGL",
"pLoxshjpJXwDhbgjfYJy",
"SjINLwFIlIEFZCbjrSFo",
"MDkVncJEVyZLJktopWje"
]
}
Move away from performing eager, fail-fast validation of mismatched
mapping to a lazy evaluation based on the fields actually used in the
query. This allows queries to run on the parts of the indices that
"work" which is not just convenient but also a necessity for large
mappings (like logging) where alignment is hard/impossible to achieve.
Fix#35659
Creates the manage_token cluster privilege and adds it to the
kibana_system role. This is required if kibana were to use the token
service for its authenticator process.
Because kibana_system already has manage_saml this effectively
only adds the privilege to create tokens.
Introduce INTERVAL as a DataType
Add INTERVAL to the grammar which supports the standard SQL declaration
(without precision):
> INTERVAL '1 23:45:01.123456789' DAY TO SECOND
but also number for single unit intervals:
> INTERVAL 1 YEAR
as well as the plurals of the units:
> INTERVAL 2 YEARS
Interval are internally supported as just another Literal being backed
by java.time.Period and java.time.Duration

- Moves disruption tests to Zen2
- Registers a few missing settings
- Removes .put(TestZenDiscovery.USE_ZEN2.getKey(), true) from tests where Zen2 is now enabled
by default through the parent test class
- Moves QuorumGatewayIT back to Zen1, as it is not stable with Zen2 as it currently relies on
dangling indices due to the lack of proper CS persistence, which triggers secondary failures

The ICU plugin provides the building blocks of an analysis chain, but doesn't actually have a prebuilt analyzer. It would be a better for users if there was a simple analyzer that they could use out of the box, and also something we can point to from the CJK Analyzer docs as a superior alternative.
