* Port a test Colin wrote for the TDigest library to validate TDigests storing over 2*MAXINT values. This appears to have been fixed in version 3.2 of TDigest, which Elasticsearch has been using for some time, so no changes were necessary to resolve this issue.
This is a follow-up to #36086. It renames the internal repository
actions to be prefixed by "internal". This allows the system user to
execute the actions.
Additionally, this PR stops casting Client to NodeClient. The client we
have is a NodeClient so executing the actions will be local.
The shard deletion logic (triggered by IndicesStore), which also leads to index metadata deletion on
non-master-eligible data nodes, currently races against the new cluster state persistence logic
triggered by accepting cluster states. One thread is writing the index metadata while another one is
deleting the index metadata, leading to exceptions and assertions tripping (see below). The solution
proposed by this PR is to move the cluster state persistence of non-master-eligible nodes back to
the cluster applier service, just as it used to be for Zen1. This ensures that the index metadata
deletion logic, which is triggered by the shard deletion logic, runs on the same thread on which we
persist the cluster state.
and replaced poll interval setting with a hardcoded poll interval.
The hard coded interval will be removed in a follow up change to make
use of cluster state API's wait_for_metatdata_version.
Before the auto following was bootstrapped from thread pool scheduler,
but now auto followers for new remote clusters are bootstrapped when
a new cluster state is published.

- make it easier to add additional testing tasks with the proper configuration and add some where they were missing.
- mute or fix failing tests
- add a check as part of testing conventions to find classes not included in any testing task.
This commit replaces usages of Streamable with Writeable for the
BaseTasksResponse / TransportTasksAction classes and subclasses of
these classes.
Note that where possible response fields were made final.

The current response format is:
```
{
"pattern1": {
...
},
"pattern2": {
...
}
}
```
The new format is:
```
{
"patterns": [
{
"name": "pattern1",
"pattern": {
...
}
},
{
"name": "pattern2",
"pattern": {
...
}
}
]
}
```
This format is more structured and more friendly for parsing and generating specs.
This is a breaking change, but it is better to do this now while ccr
is still a beta feature than later.
Follow up from #36049
If the randomly selected port was already in use the Kerberos
tests would fail. This commit adds check to see if the network
port is available and if not continue to find one for KDC server.
If it does not find port after 100 retries it throws an exception.
Closes#34261
Made credentials mandatory for xpack migrate tool.
Closes#29847.
The x-pack user and roles APIs aren't available unless security is enabled, so the tool should always be called with the -u and -p options specified.
Add a more detailed section about what exceptions to expect from the blocking
calls in this class and removing the mostly redundant mentions of the
IOExceptions from each method javadoc since it doesn't give much details about
the expected exceptions anyway.
Closes#30334
This commit adds an empty CcrRepository snapshot/restore repository.
When a new cluster is registered in the remote cluster settings, a new
CcrRepository is registered for that cluster.
This is implemented using a new concept of "internal repositories".
RepositoryPlugin now allows implementations to return factories for
"internal repositories". The "internal repositories" are different from
normal repositories in that they cannot be registered through the
external repository api. Additionally, "internal repositories" are local
to a node and are not stored in the cluster state.
The repository will be unregistered if the remote cluster is removed.
* Move `createRepository` call out of cluster state tasks
* Now only `RepositoriesService#applyClusterState` manipulates `this.repositories`
* Closes#9488
This commit makes `document`, `update`, `explain`, `termvectors` and `mapping`
typeless APIs work on indices that have a type whose name is not `_doc`.
Unfortunately, this needs to be a bit of a hack since I didn't want calls with
random type names to see documents with the type name that the user had chosen
upon type creation.
The `explain` and `termvectors` do not support being called without a type for
now so the test is just using `_doc` as a type for now, we will need to fix
tests later but this shouldn't require further changes server-side since passing
`_doc` as a type name is what typeless APIs do internally anyway.

By default gateway.recover_after_master_nodes is set to
discovery.zen.minimum_master_nodes but in this Zen2 test this is set to an
unreasonably large value. This change updates it so the cluster can properly
form.
It is important that all shards of a given index have the same
`indexCreatedVersionMajor` to Lucene, or eg. merging those shards is going to
be considered illegal. At the moment, we use the latest Lucene version when
creating a shard, which could cause shards to have different created versions
eg. in case of forced allocation. This commit makes sure to reuse the
appropriate Lucene version in order to avoid such issues.
Closes#33826
Today we configure the soft-deletes field iff soft-deletes enabled.
Although this choice was correct, it prevents an engine with
soft-deletes disabled from opening a Lucene index with soft-deletes.
Moreover, this change should not have any side-effect if a Lucene index
does not have any soft-deletes.
Relates #36141
AutoFollowCoordinator should take into account that after auto following
an index and while updating that a leader index has been followed, that
the auto follow pattern may have been removed via delete auto follow patterns
api.
Also fixed a bug that when a remote cluster connection has been removed,
the auto follow coordinator does not die when it tries get a remote client for
that cluster.
Closes#35480
This commit implements proper metadata recovery for Zen2.
GatewayService is responsible for the recovery. In Zen1 GatewayService
creates an instance of Gateway, that is used to reach out to other cluster
nodes, get their state and calculate the most up-to-date state based on
versions. After that Gateway performs upgrade and archival of
ClusterSettings and closes bad indices. Then recovered state is passed to GatewayService.GatewayRecoveryListener that mixes up current state
and restored state, removes state not recovered block, creates the
routing table and performs re-routing.
In Zen2 we should perform this kind of logic on cluster startup, except
mixing state (because there is nothing to mix) and opening routing table.
This commit refactors out all `ClusterUpdate` functions in a separate class
`ClusterStateUpdaters`, which is used by `Gateway` and `GatewayService`
in case of Zen1, and by `GatewayMetaState` and `GatewayService` in case of
Zen2.
This commit also switches all integration tests that are already using Zen2 from
InMemoryPersistedState to GatewayMetaState.
This commit changes how an operation which requires all index shard
operations permits is executed when a primary term update is required:
the operation and the update are combined so that the operation is
executed after the primary term update under the same blocking
operation.

This test suite can stop all the shared master-eligible nodes, which breaks the
cluster since any non-shared master-eligible nodes are stopped first in the
reset process between tests.
Since this test suite can leave the cluster in this somewhat broken state, it
seems best that it uses a new cluster for each test.
