Fix bug in IndexResolver that caused conflicts in multi-field types to
be ignored up (causing the query to fail later on due to mapping
conflicts).
The issue was caused by the multi-field which forced the parent creation
before checking its validity across mappings

This change adds supports for the concurrent refresh of access
tokens as described in #36872
In short it allows subsequent client requests to refresh the same token that
come within a predefined window of 60 seconds to be handled as duplicates
of the original one and thus receive the same response with the same newly
issued access token and refresh token.
In order to support that, two new fields are added in the token document. One
contains the instant (in epoqueMillis) when a given refresh token is refreshed
and one that contains a pointer to the token document that stores the new
refresh token and access token that was created by the original refresh.
A side effect of this change, that was however also a intended enhancement
for the token service, is that we needed to stop encrypting the string
representation of the UserToken while serializing. ( It was necessary as we
correctly used a new IV for every time we encrypted a token in serialization, so
subsequent serializations of the same exact UserToken would produce
different access token strings)
This change also handles the serialization/deserialization BWC logic:
- In mixed clusters we keep creating tokens in the old format and
consume only old format tokens
- In upgraded clusters, we start creating tokens in the new format but
still remain able to consume old format tokens (that could have been
created during the rolling upgrade and are still valid)

Backport support for replicating closed indices (#39499)
Before this change, closed indexes were simply not replicated. It was therefore
possible to close an index and then decommission a data node without knowing
that this data node contained shards of the closed index, potentially leading to
data loss. Shards of closed indices were not completely taken into account when
balancing the shards within the cluster, or automatically replicated through shard
copies, and they were not easily movable from node A to node B using APIs like
Cluster Reroute without being fully reopened and closed again.
This commit changes the logic executed when closing an index, so that its shards
are not just removed and forgotten but are instead reinitialized and reallocated on
data nodes using an engine implementation which does not allow searching or
indexing, which has a low memory overhead (compared with searchable/indexable
opened shards) and which allows shards to be recovered from peer or promoted
as primaries when needed.
This new closing logic is built on top of the new Close Index API introduced in
6.7.0 (#37359). Some pre-closing sanity checks are executed on the shards before
closing them, and closing an index on a 8.0 cluster will reinitialize the index shards
and therefore impact the cluster health.
Some APIs have been adapted to make them work with closed indices:
- Cluster Health API
- Cluster Reroute API
- Cluster Allocation Explain API
- Recovery API
- Cat Indices
- Cat Shards
- Cat Health
- Cat Recovery

Currently there are two security tests that specifically target the
netty security transport. This PR moves the client authentication tests
into `AbstractSimpleSecurityTransportTestCase` so that the nio transport
will also be tested.
Additionally the work to build transport configurations is moved out of
the netty transport and tested independently.
This changes the name of the internal security index to ".security-7",
but supports indices that were upgraded from earlier versions and use
the ".security-6" name.
In all cases, both ".security-6" and ".security-7" are considered to
be restricted index names regardless of which name is actually in use
on the cluster.

Some small fix for the `x-pack` rest api spec.

possible paths since the path parameters are not required.
This fix aligns the document with the rest of the spec,
where all the possible combinations are listed.
It is possible that the Unfollow API may fail to release shard history
retention leases when unfollowing, so this needs to be handled by the
ILM Unfollow action. There's nothing much that can be done automatically
about it from the follower side, so this change makes the ILM unfollow
action simply ignore those failures.
This change is a backport of #39252
- Fixes TokenBackwardsCompatibilityIT: Existing tests seemed to made
the assumption that in the oneThirdUpgraded stage the master node
will be on the old version and in the twoThirdsUpgraded stage, the
master node will be one of the upgraded ones. However, there is no
guarantee that the master node in any of the states will or will
not be one of the upgraded ones.
This class now tests:
- That we can generate and consume tokens before we start the
rolling upgrade.
- That we can consume tokens generated in the old cluster during
all the stages of the rolling upgrade.
- That while on a mixed cluster, when/if the master node is
upgraded, we can generate, consume and refresh a token
- That after the rolling upgrade, we can consume a token
generated in an old cluster and can invalidate it so that it
can't be used any more.
- Ensures that during the rolling upgrade, the upgraded nodes have
the same configuration as the old nodes. Specifically that the
file realm we use is explicitly named `file1`. This is needed
because while attempting to refresh a token in a mixed cluster
we might create a token hitting an old node and attempt to refresh
it hitting a new node. If the file realm name is not the same, the
refresh will be seen as being made by a "different" client, and
will, thus, fail.
- Renames the Authentication variable we check while refreshing a
token to be clientAuth in order to make the code more readable.
Some of the above were possibly causing the flakiness of #37379

* Remove Hipchat support from Watcher (#39199)
Hipchat has been shut down and has previously been deprecated in
Watcher (#39160), therefore we should remove support for these actions.
* Add migrate note
With this change, we won't wait for the local checkpoint to advance to
the max_seq_no before starting phase2 of peer-recovery. We also remove
the sequence number range check in peer-recovery. We can safely do these
thanks to Yannick's finding.
The replication group to be used is currently sampled after indexing
into the primary (see `ReplicationOperation` class). This means that
when initiating tracking of a new replica, we have to consider the
following two cases:
- There are operations for which the replication group has not been
sampled yet. As we initiated the new replica as tracking, we know that
those operations will be replicated to the new replica and follow the
typical replication group semantics (e.g. marked as stale when
unavailable).
- There are operations for which the replication group has already been
sampled. These operations will not be sent to the new replica. However,
we know that those operations are already indexed into Lucene and the
translog on the primary, as the sampling is happening after that. This
means that by taking a snapshot of Lucene or the translog, we will be
getting those ops as well. What we cannot guarantee anymore is that all
ops up to `endingSeqNo` are available in the snapshot (i.e. also see
comment in `RecoverySourceHandler` saying `We need to wait for all
operations up to the current max to complete, otherwise we can not
guarantee that all operations in the required range will be available
for replaying from the translog of the source.`). This is not needed,
though, as we can no longer guarantee that max seq no == local
checkpoint.

Finally! This commit should fix the issues with the CCR retention lease
that has been plaguing build failures. The issue here is that we are
trying to prevent the clear session requests from being executed until

not blocking them when they are proxied through another node. This
commit addresses that.

This commit changes the sort order of shard stats that are collected in
CCR retention lease integration tests. This change is done so that
primaries appear first in sort order.
This test fails rarely but it is flaky in its current form. The problem
here is that we lack a guarantee on the retention leases having been
synced to all shard copies. We need to sleep long enough to ensure that
that occurs, and then we can sample the retention leases, possibly sleep
again (we usually will not have too since the first sleep will have been
long enough to allow a sync and a renewal to happen, if one was going to
happen), and the sample the retention leases for comparison.
Closes#39331
The shard logged here is the leader shard but it should be the follower
shard since this background retention lease renewal is happening on the
follower side. This commit fixes that.
This commit simplifies the use of transport mocking in the CCR retention
lease integration tests. Instead of adding a send rule between nodes, we
add a default send rule. This greatly simplifies the code here, and
speeds the test up a little bit too.
This fixes#39245. Currently it is possible in this test that the clear
session call times-out. This means that the index commit will not be
released and there will be an assertion triggered in the test teardown.
This commit ensures that we wipe the leader index in the test to avoid
this assertion.
It is okay if the clear session call times-out in normal usage. This
scenario is unavoidable due to potential network issues. We have a local
timeout on the leader to clean it up when this scenario happens.
The assertBusy() that waits the default 10 seconds for a
datafeed to complete very occasionally times out on slow
machines. This commit increases the timeout to 60 seconds.
It will almost never actually take this long, but it's
better to have a timeout that will prevent time being
wasted looking at spurious test failures.
This test should no longer pass when the functionality it is intended to
test is broken, as it now indexes a number of documents and verifies
that the index is staying on the same step until after indexing and
replication of those documents is finished. This prevents the test from
passing if the leader index progresses in its lifecycle during that time.
This test failed once in a very long time with the assertion
that there is no document for the `non_existing_job` in the
state index. I could not see how that is possible and I cannot
reproduce. With this commit the failure message will reveal
some examples of the left behind docs which might shed a light
about what could go wrong.
With this commit we remove all usages of the deprecated method
`ExceptionsHelper#detailedMessage` in tests. We do not address
production code here but rather in dedicated follow-up PRs to keep the
individual changes manageable.

This commit makes `TransformIntegrationTests` into a standard integration test, as

The simplification may help with flakiness we've observed `TimeWarp, as in #37882.
The SchedulerEngine is used in several places in our code and not all
of these usages properly stopped the SchedulerEngine, which could lead
to test failures due to leaked threads from the SchedulerEngine. This

that cause CI failures and noise.
Closes#38875
Currently remote compression and ping schedule settings are dynamic.
However, we do not listen for changes. This commit adds listeners for

Sleeps in tests smell funny, and we try to avoid them to the extent
possible. We are using a small one in a CCR test. This commit clarifies
the purpose of that sleep by adding a comment explaining it. We also
removed a hard-coded value from the test, that if we ever modified the
value higher up where it was set, we could end up forgetting to change
the value here. Now we ensure that these would move in lock step if we
ever maintain them later.
We have some CCR tests where we use mock transport send rules to control
the behavior that we desire in these tests. Namely, we want to simulate
an exception being thrown on the leader side, or a variety of other
situations. These send rules were put in place between the data nodes on
each side. However, it might not be the case that these requests are
being sent between data nodes. For example, a request that is handled on
a non-data master node would not be sent from a data node. And it might
not be the case that the request is sent to a data node, as it could be
proxied through a non-data coordinating node. This commit addresses this
by putting these send rules in places between all nodes on each side.
Closes#39011Closes#39201
`ReadOnlyEngine` never recovers operations from translog and never
updates translog information in the index shard's recovery state, even
though the recovery state goes through the `TRANSLOG` stage during
the recovery. It means that recovery information for frozen shards indicates
an unkown number of recovered translog ops in the Recovery APIs
(translog_ops: `-1` and translog_ops_percent: `-1.0%`) and this is confusing.
This commit changes the `recoverFromTranslog()` method in `ReadOnlyEngine`
so that it always recover from an empty translog snapshot, allowing the recovery
state translog information to be correctly updated.

Initially in #38910, ShardFollowTask was reusing ImmutableFollowParameters'
serialization logic. After merging, bwc tests failed sometimes and
the binary serialization that ShardFollowTask was originally was using
was added back. ImmutableFollowParameters is using optional fields (optional vint)
while ShardFollowTask was not (vint).
Today we always refresh when looking up the primary term in
FollowingEngine. This is not necessary for we can simply
return none for operations before the global checkpoint.
The follower won't always have the same history as the leader for its
soft-deletes retention can be different. However, if some operation
exists on the history of the follower, then the same operation must
exist on the leader. This change relaxes the history check in
ShardFollowTaskReplicationTests.

This change aims to fix failures in the session factory load balancing
tests that mock failure scenarios. For these tests, we randomly shut
down ldap servers and bind a client socket to the port they were
listening on. Unfortunately, we would occasionally encounter failures
in these tests where a socket was already in use and/or the port
we expected to connect to was wrong and in fact was to one of the ldap
instances that should have been shut down.
The failures are caused by the behavior of certain operating systems
when it comes to binding ports and wildcard addresses. It is possible
for a separate application to be bound to a wildcard address and still
allow our code to bind to that port on a specific address. So when we
close the server socket and open the client socket, we are still able
to establish a connection since the other application is already
listening on that port on a wildcard address. Another variant is that
the os will allow a wildcard bind of a server socket when there is
already an application listening on that port for a specific address.
In order to do our best to prevent failures in these scenarios, this
change does the following:
1. Binds a client socket to all addresses in an awaitBusy
2. Adds assumption that we could bind all valid addresses
3. In the case that we still establish a connection to an address that
we should not be able to, try to bind and expect a failure of not
being connected
Closes#32190
This commit fixes a broken CCR retention lease unfollow test. The
problem with the test is that the random subset of shards that we picked
to disrupt would not necessarily overlap with the actual shards in
use. We could take a non-empty subset of [0, 3] (e.g., { 2 }) when the
only shard IDs in use were [0, 1]. This commit fixes this by taking into
account the number of shards in use in the test.
With this change, we also take measure to ensure that a successful
branch is tested more frequently than would otherwise be the case. On
that branch, we want to sometimes pretend that the retention lease is
already removed. The randomness here was also sometimes selecting a
subset of shards that did not overlap with the shards actually in use
during the test. While this does not break the test, it is confusing and
reduces the amount of coverage of that branch.

In most of the places we avoid creating the `.security` index (or updating the mapping)
for read/search operations. This is more of a nit for the case of the getRole call,
that fixes a possible mapping update during a get role, and removes a dead if branch
about creating the `.security` index.
This commit attempts to remove the retention leases on the leader shards
when unfollowing an index. This is best effort, since the leader might
not be available.
This defaults to "true" (current behavior) and will throw an exception
if there is a property that cannot be recognized. If "false", it will
ignore anything unrecognizable.

The ML memory tracker does searches against ML results
and config indices. These searches can be asynchronous,
and if they are running while the node is closing then
they can cause problems for other components.
This change adds a stop() method to the MlMemoryTracker
that waits for in-flight searches to complete. Once
stop() has returned the MlMemoryTracker will not kick
off any new searches.
The MlLifeCycleService now calls MlMemoryTracker.stop()
before stopping stopping the node.
Fixes#37117
These two changes are interlinked.
Before this change unsetting ML upgrade mode would wait for all
datafeeds to be assigned and not waiting for their corresponding
jobs to initialise. However, this could be inappropriate, if
there was a reason other that upgrade mode why one job was unable
to be assigned or slow to start up. Unsetting of upgrade mode
would hang in this case.
This change relaxes the condition for considering upgrade mode to
be unset to simply that an assignment attempt has been made for
each ML persistent task that did not fail because upgrade mode
was enabled. Thus after unsetting upgrade mode there is no
guarantee that every ML persistent task is assigned, just that
each is not unassigned due to upgrade mode.
In order to make setting upgrade mode work immediately after
unsetting upgrade mode it was then also necessary to make it
possible to stop a datafeed that was not assigned. There was
no particularly good reason why this was not allowed in the past.
It is trivial to stop an unassigned datafeed because it just
involves removing the persistent task.
Prior to this commit, if during fetch leader / follower GCP
a fatal error occurred, then the shard follow task was removed.
This is unexpected, because if such an error occurs during the lifetime of shard follow task then replication is stopped and the fatal error flag is set. This allows the ccr stats api to report the fatal exception that has occurred (instead of the user grepping through the elasticsearch logs).
This issue was found by a rare failure of the `FollowStatsIT#testFollowStatsApiIncludeShardFollowStatsWithRemovedFollowerIndex` test.

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:

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.
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
following engine), we first add it to Lucene, then add it to translog,
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.
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.
Closes#38318Closes#36789
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.
