We should not create a follower index and abort a follow request if the
leader does not have soft-deletes. Moreover, we also should not
auto-follow an index if it does not have soft-deletes.

With this change, we apply the common test config automatically to all
newly created tasks instead of opting in specifically.
For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.
The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.
Implemented null handling for both the value tested but also for
values inside the list of values tested against.
The null handling is implemented for local processors, painless scripts
and Lucene Terms queries making it available for `IN` expressions occuring
in `SELECT`, `WHERE` and `HAVING` clauses.

#33708 introduced a strict deprecation mode that makes a REST request
fail if there is a warning header in the response returned by
Elasticsearch (usually a deprecation message signaling that a feature
or a field has been deprecated).
This change adds the strict deprecation mode into the REST integration
tests, and makes the tests fail if a deprecated feature is used. Also
any test using a deprecated feature has been modified to pass the build.
The YAML integration tests already analyzed HTTP warnings so they do
not use this mode, keeping their "expected vs actual" behavior.
Per #31717 this commit changes the defaults to the following:
Batch size of 5120 ops.
Maximum of 12 concurrent read requests.
Maximum of 9 concurrent write requests.
This is not necessarily our final values but it's good to have these as defaults for the purposes of initial testing.
The changes introduced in cca1a2a mean that we should
not encrypt the public keys that might be generated by
the key-pair-generator when storing the file, as the code
that would consume them assumes that they are not encrypted
* Change the `TransportPauseFollowAction` to extend from `TransportMasterNodeAction`
instead of `HandledAction`, this removes a sync cluster state api call.
* Introduced `ResponseHandler` that removes duplicated code in `TransportPauseFollowAction` and
`TransportResumeFollowAction`.
* Changed `PauseFollowAction.Request` to not use `readFrom()`.
In a future major version, we will be introducing a soft limit on the
number of shards in a cluster based on the number of nodes in the
cluster. This limit will be configurable, and checked on operations
which create or open shards and issue a warning if the operation would
take the cluster over the limit.
There is an option to enable strict enforcement of the limit, which
turns the warnings into errors. In a future release, the option will be
removed and strict enforcement will be the default (and only) behavior.
- Restrict visibility of Aggregators and Factories
- Move PipelineAggregatorBuilders up a level so it is consistent with
AggregatorBuilders
- Checkstyle line length fixes for a few classes
- Minor odds/ends (swapping to method references, formatting, etc)
Both testFollowIndexAndCloseNode and testFailOverOnFollower failed
because they responded to the FollowTask a TransportService closed
exception which is currently considered as a fatal error. This behavior
is not desirable since a closing node can throw that exception, and we
should retry in that case.
This change adds TransportService closed error to the list of retryable
errors.
Closes#34694
As part of this change the leader index name and leader cluster name are
stored in the CCR metadata in the follow index. The resume follow api
will read that when a resume follow request is executed.
We should delete a job by directly talking to the allocated
task and telling it to shutdown. Today we shut down a job
via the persistent task framework. This is not ideal because,
while the job has been removed from the persistent task
CS, the allocated task continues to live until it gets the
shutdown message.
This means a user can delete a job, immediately delete
the rollup index, and then see new documents appear in
the just-deleted index. This happens because the indexer
in the allocated task is still running and indexes a few
more documents before getting the shutdown command.
In this PR, the transport action is changed to a TransportTasksAction,
and we invoke onCancelled() directly on the matching job.
The race condition still exists after this PR (albeit less likely),
but this was a precursor to fixing the issue and a self-contained
chunk of code. A second PR will followup to fix the race itself.
Since #34412 and #34474, a follower must have soft-deletes enabled
to work correctly. This change requires soft-deletes on the follower.

This fixes a bug about aliases authorization.
That is, a user might see aliases which he is not authorized to see.
This manifests when the user is not authorized to see any aliases
and the `GetAlias` request is empty which normally is a marking
that all aliases are requested. In this case, no aliases should be
returned, but due to this bug, all aliases will have been returned.
Extend querying support on multiple indices from being strictly
identical to being just compatible.
Use FieldCapabilities API (extended through #33803) for mapping merging.

* Changed the resource id of auto follow patterns to be a user defined name
instead of being the leader cluster alias name.
* Fail when an unfollowed leader index matches with two or more auto follow patterns.
Implement the functionality to translate the
`field IN (value1, value2,...)` expressions to proper Lucene queries
or painless script or local processors depending on the use case.
The `IN` expression can be used in SELECT, WHERE and HAVING clauses.
Closes: #32955
`CONVERT` works exactly like cast with slightly different syntax:
`CONVERT(<value>, <data_type)` as opposed to `CAST(<value> AS <data_type>)`
Moreover it support format of the MS-SQL data types `SQL_<type>`,
e.g.: `SQL_INTEGER`
Closes: #34513
JDK11 introduced some changes with the SSLEngine. A number of error
messages were changed. Additionally, there were some behavior changes
in regard to how the SSLEngine handles closes during the handshake
process. This commit updates our tests and SSLDriver to support these
changes.
All of the tests in PainlessDomainSplitIT have an awaitsfix, which
causes the build to fail since no tests are run. This adds an empty
test to get the build going again.

The security native stores follow a pattern where
`SecurityIndexManager#prepareIndexIfNeededThenExecute` wraps most calls
made for the security index. The reasoning behind this was to check if
the security index had been upgraded to the latest version in a
consistent manner. However, this has the potential side effect that a
read will trigger the creation of the security index or an updating of
its mappings, which can lead to issues such as failures due to put
mapping requests timing out even though we might have been able to read
from the index and get the data necessary.
This change introduces a new method, `checkIndexVersionThenExecute`,
that provides the consistent checking of the security index to make
sure it has been upgraded. That is the only check that this method
performs prior to running the passed in operation, which removes the
possible triggering of index creation and mapping updates for reads.
Additionally, areas where we do reads now check the availability of the
security index and can short circuit requests. Availability in this
context means that the index exists and all primaries are active.
This is the fixed version of #34246, which was reverted.

We should be consistent here. We were already using the casing "Ccr" and
this is the preferred casing for Java class names. This commit adjusts
the names of some classes that were using the casing "CCR" to be "Ccr".
In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
Since #34288, we might hit deadlock if the FollowTask has more fetchers
than writers. This can happen in the following scenario:
Suppose the leader has two operations [seq#0, seq#1]; the FollowTask has
two fetchers and one writer.
1. The FollowTask issues two concurrent fetch requests: {from_seq_no: 0,
num_ops:1} and {from_seq_no: 1, num_ops:1} to read seq#0 and seq#1
respectively.
2. The second request which fetches seq#1 completes before, and then it
triggers a write request containing only seq#1.
3. The primary of a follower fails after it has replicated seq#1 to
replicas.
4. Since the old primary did not respond, the FollowTask issues another
write request containing seq#1 (resend the previous write request).
5. The new primary has seq#1 already; thus it won't replicate seq#1 to
replicas but will wait for the global checkpoint to advance at least
seq#1.
The problem is that the FollowTask has only one writer and that writer
is waiting for seq#0 which won't be delivered until the writer completed.
This PR proposes to replicate existing operations with the old primary
term (instead of the current term) on the follower. In particular, when
the following primary detects that it has processed an process already,
it will look up the term of an existing operation with the same seq_no
in the Lucene index, then rewrite that operation with the old term
before replicating it to the following replicas. This approach is
wait-free but requires soft-deletes on the follower.
