David Roberts b660d2cac6 [ML] More advanced post-test cleanup of ML indices (#39049)
The .ml-annotations index is created asynchronously when
some other ML index exists.  This can interfere with the
post-test index deletion, as the .ml-annotations index
can be created after all other indices have been deleted.

This change adds an ML specific post-test cleanup step
that runs before the main cleanup and:

1. Checks if any ML indices exist
2. If so, waits for the .ml-annotations index to exist
3. Deletes the other ML indices found in step 1.
4. Calls the super class cleanup

This means that by the time the main post-test index
cleanup code runs:

1. The only ML index it has to delete will be the
   .ml-annotations index
2. No other ML indices will exist that could trigger
   recreation of the .ml-annotations index

Integrate retention leases to recovery from remote (#38829)
This commit is the first step in integrating shard history retention
leases with CCR. In this commit we integrate shard history retention
leases with recovery from remote. Before we start transferring files, we
take out a retention lease on the primary. Then during the file copy
phase, we repeatedly renew the retention lease. Finally, when recovery
from remote is complete, we disable the background renewing of the
retention lease.

Add get file chunk timeouts with listener timeouts (#38758)
This commit adds a `ListenerTimeouts` class that will wrap a
`ActionListener` in a listener with a timeout scheduled on the generic
thread pool. If the timeout expires before the listener is completed,
`onFailure` will be called with an `ElasticsearchTimeoutException`.

Timeouts for the get ccr file chunk action are implemented using this
functionality. Additionally, this commit attempts to fix #38027 by also
blocking proxied get ccr file chunk actions. This test being un-muted is
useful to verify the timeout functionality.

Today when processing an operation on a replica engine (or the

then finally marks its seq_no as completed. If a flush occurs after step1,
but before step-3, the max_seq_no in the commit's user_data will be
smaller than the seq_no of some documents in the Lucene commit.

Nhat Nguyen 20755e666c Reduce global checkpoint sync interval in disruption tests (#38931)
We verify seq_no_stats is aligned between copies at the end of some
disruption tests. Sometimes, the assertion `assertSeqNos` is tripped due
to a lagged global checkpoint on replicas. The global checkpoint on
replicas is lagged because we sync the global checkpoint 30 seconds (by
default) after the last replication operation. This change reduces the
global checkpoint sync-internal to 1s in the disruption tests.

Address some CCR REST test case flakiness (#38975)
The CCR REST tests that rely on these assertions are flaky. They are
flaky since the introduction of recovery from the remote.

The underlying problem is this: these tests are making assertions about
the number of operations read by the shard following task. However, with
recovery from remote, we no longer have guarantees that the assumptions
these tests were relying on hold. Namely, these tests were assuming that
the only way that a document could land in the follower index is via the
shard following task. With recovery from remote, there is another way,
which is via the files that are copied over during the recovery
phase. Most of the time this will not be a problem because with the
small number of documents that we are indexing in these tests, it is
usally not the case that a flush would occur and so there would not be
any documents in the files copied over. However, a flush can occur any
time at which point all of the indexed documents could end up in a safe
commit and copied over during recovery from remote. This commit modifies
these assertions to ones that are not prone to this issue, yet still
validate the health of the follower shard.

Fix intermittent failure in ApiKeyIntegTests (#38627) (#38935)
Few tests failed intermittently and most of the
times due to invalidated or expired keys that were
deleted were still reported in search results.
This commit removes the test and adds enhancements
to other tests testing different scenario's.

When ExpiredApiKeysRemover is triggered, the tests
did not await its termination thereby sometimes
the results would be wrong for a search operation.

DELETE_INTERVAL setting has been further reduced to
100ms so we can trigger ExpiredApiKeysRemover faster.

Yannick Welsch d55e52223f Smarter CCR concurrent file chunk fetching (#38841)
The previous logic for concurrent file chunk fetching did not allow for multiple chunks from the same
file to be fetched in parallel. The parallelism only allowed to fetch chunks from different files in
parallel. This required complex logic on the follower to be aware from which file it was already
fetching information, in order to ensure that chunks for the same file would be fetched in sequential
order. During benchmarking, this exhibited throughput issues when recovery came towards the end,
where it would only be sequentially fetching chunks for the same largest segment file, with
throughput considerably going down in a high-latency network as there was no parallelism anymore.

The new logic here follows the peer recovery model more closely, and sends multiple requests for
the same file in parallel, and then reorders the results as necessary. Benchmarks show that this
leads to better overall throughput and the implementation is also simpler.

[Monitoring] Remove `include_type_name` parameter from GET _template request (#38925)
Backport of #38818 to `7.x`. Original description:

The HTTP exporter code in the Monitoring plugin makes `GET _template` requests to check for existence of templates. These requests don't need to pass the `include_type_name` query parameter so this PR removes it from the request. This should remove the following deprecation log entries on the Monitoring cluster in 7.0.0 onwards:

```

Use consistent view of realms for authentication (#38815)
This change updates the authentication service to use a consistent view
of the realms based on the license state at the start of
authentication. Without this, the license can change during
authentication of a request and it will result in a failure if the
realm that extracted the token is no longer in the realm list. This
manifests in some tests as an authentication failure that should never
really happen; one example would be the test framework's transport
client user should always have a succesful authentication but in the
LicensingTests this can fail and will show up as a
NoNodeAvailableException.

Additionally, the licensing tests have been updated to ensure that
there is consistency when changing the license. The license is changed
by modifying the internal xpack license state on each node, which has
no protection against be changed by some pending cluster action. The
methods to disable and enable now ensure we have a green cluster and
that the cluster is consistent before returning.

Albert Zaharovits 6243a9797f _cat/indices with Security, hide names when wildcard (#38824)
This changes the output of the `_cat/indices` API with `Security` enabled.

It is possible to only display the index name (and possibly the index
health, depending on the request options) but not its stats (doc count, merges,
size, etc). This is the case for closed indices which have index metadata in the
cluster state but no associated shards, hence no shard stats.
However, when `Security` is enabled, and the request contains wildcards,
**open** indices without stats are a common occurrence. This is because the
index names in the response table are picked up directly from the cluster state
which is not filtered by `Security`'s _indexNameExpressionResolver_, unlike the
stats data which is populated by the indices stats API which does go through the
index name resolver.
This is a bug, because it is circumventing `Security`'s function to hide
unauthorized indices.

This has been fixed by displaying the index names as they are resolved by the indices
stats API. The outputs of these two APIs is now very similar: same index names,
similar data but different format.

Backport rolling upgrade multi cluster module (#38859)
* Add rolling upgrade multi cluster test module (#38277)

This test starts 2 clusters, each with 3 nodes.
First the leader cluster is started and tests are run against it and
then the follower cluster is started and tests execute against this two cluster.

Then the follower cluster is upgraded, one node at a time.
After that the leader cluster is upgraded, one node at a time.
Every time a node is upgraded tests are ran while both clusters are online.
(and either leader cluster has mixed node versions or the follower cluster)

This commit only tests CCR index following, but could be used for CCS tests as well.
In particular for CCR, unidirectional index following is tested during a rolling upgrade.
During the test several indices are created and followed in the leader cluster before or
while the follower cluster is being upgraded.

This tests also verifies that attempting to follow an index in the upgraded cluster
from the not upgraded cluster fails. After both clusters are upgraded following the
index that previously failed should succeed.

Improve CcrRepositoryIT mappings tests (#38817)
Currently we index documents concurrently to attempt to ensure that we
update mappings during the restore process. However, this does not
actually test that the mapping will be correct and is dangerous as it
can lead to a misalignment between the max sequence number and the local
checkpoint. If these are not aligned, peer recovery cannot be completed
without initiating following which this test does not do. That causes
teardown assertions to fail.

This commit removes the concurrent indexing and flushes after the
documents are indexed. Additionally it modifies the mapping specific
test to ensure that there is a mapping update when the restore session
is initiated. This mapping update is picked up at the end of the restore
by the follower.

This change removes the pinning of TLSv1.2 in the
SSLConfigurationReloaderTests that had been added to workaround an
issue with the MockWebServer and Apache HttpClient when using TLSv1.3.
The way HttpClient closes the socket causes issues with the TLSv1.3
SSLEngine implementation that causes the MockWebServer to loop

change wraps the created http connection in a way that allows us to
override the closing behavior of HttpClient.

An upstream request with HttpClient has been opened at
https://issues.apache.org/jira/browse/HTTPCORE-571 to see if the method
of closing can be special cased for SSLSocket instances.

This is caused by a JDK bug, JDK-8214418 which is fixed by

Alexander Reelsen 6ae7915b9d Fix exporter tests to have reasonable dates (#38436)
The java time formatter used in the exporter adds a plus sign to the
year, if a year with more than five digits is used. This changes the
creation of those timestamp to only have a date up to 9999.

Specialize pre-closing checks for engine implementations (#38702) (#38722)
The Close Index API has been refactored in 6.7.0 and it now performs 
pre-closing sanity checks on shards before an index is closed: the maximum 
sequence number must be equals to the global checkpoint. While this is a 
strong requirement for regular shards, we identified the need to relax this 
check in the case of CCR following shards.

The following shards are not in charge of managing the max sequence 
number or global checkpoint, which are pulled from a leader shard. They 
also fetch and process batches of operations from the leader in an unordered 
way, potentially leaving gaps in the history of ops. If the following shard lags 
a lot it's possible that the global checkpoint and max seq number never get 
in sync, preventing the following shard to be closed and a new PUT Follow 
action to be issued on this shard (which is our recommended way to 
resume/restart a CCR following).

This commit allows each Engine implementation to define the specific 
verification it must perform before closing the index. In order to allow 
following/frozen/closed shards to be closed whatever the max seq number 
or global checkpoint are, the FollowingEngine and ReadOnlyEngine do 
not perform any check before the index is closed.
