`enum` is a single option from a known list of `options`
`list` is an array of unknown values
`flags` are multiple options from a list of known `options`.
We don't support the `flags` type but a `list` with `options` acts as one. This is already the case for other API's taking metric such as `node.stats.json`.
watcher.stats behaves the same as other API's as `metrics` and as such accepts the following `GET _xpack/watcher/stats/queued_watches,current_watches`

ML has historically used doc as the single mapping type but reindex in 7.x
will change the mapping to _doc. Switching to the typeless APIs handles
case where the mapping type is either doc or _doc. This change removes
deprecated typed usages.
This cleans up the Engine implementation by separating the sequence number generation from the
planning step in the engine, to avoid for the planning step to have any side effects. This makes it
easier to see that every sequence number is properly accounted for.
Fix bug in IndexResolver that caused conflicts in multi-field types to

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.
Backport of: #39337
Some small fix for the `x-pack` rest api spec.

* In `security.get_privileges.json` there were missing all the
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)

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
opposed to using `TimeWarp`, which registers the mock component
`ScheduleEngineTriggerMock` to trigger watches.
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
change adds stopping to these usages in order to avoid the thread leaks
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

stop() has returned the MlMemoryTracker will not kick
off any new searches.
The MlLifeCycleService now calls MlMemoryTracker.stop()
before stopping stopping the node.

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:
1. The only ML index it has to delete will be the

2. No other ML indices will exist that could trigger

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

`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

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.
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.
Closes#38408
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.
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:
```
[types removal] Specifying include_type_name in get index template requests is deprecated.
```
This change makes the writing of new usage data conditional based on

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.
Closes#30301
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.
Closes#37190
Right now there is no way to determine whether the
token service or API key service is enabled or not.
This commit adds support for the enabled status of

* 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.

When shutting down Watcher, the `bulkProcessor` is null if watcher has been

Resolves#38798
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.
Instead of using `WarningsHandler.PERMISSIVE`, we only match warnings
that are due to types removal.
This PR also renames `allowTypeRemovalWarnings` to `allowTypesRemovalWarnings`.

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.

Added a constructor accepting `StreamInput` as argument, which allowed to

Removed a test only constructor in favour of invoking the existing
constructor that takes a `SearchRequest` as first argument.
Also removed profile members and related methods as they were all unused.

* Enhance parsing of StatusCode in SAML Responses
<Status> elements in a failed response might contain two nested
<StatusCode> elements. We currently only parse the first one in
order to create a message that we attach to the Exception we return
and log. However this is generic and only gives out informarion
about whether the SAML IDP believes it's an error with the
request or if it couldn't handle the request for other reasons. The
encapsulated StatusCode has a more interesting error message that
potentially gives out the actual error as in Invalid nameid policy,
authentication failure etc.
This change ensures that we print that information also, and removes
Message and Details fields from the message when these are not
part of the Status element (which quite often is the case)
When the millisecond part of a timestamp is 0 the toString
representation in java-time is omitting the millisecond part (joda was
not). The Search response is returning timestamps formatted with
WatcherDateTimeUtils, therefore comparisons of strings should be done
with the same formatter

We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.
The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).
Given all these issues, it seems that this custom timeout mechanism
gives little benefits while causing a lot of harm. We should rather rely
on connect and socket timeout exposed by the underlying http client
and accept that a request can overall take longer than the configured
timeout, which is the case even with a single retry anyways.
This commit removes the `maxRetryTimeout` setting and all of its usages.
This commit adds an authentication cache for API keys that caches the
hash of an API key with a faster hash. This will enable better
performance when API keys are used for bulk or heavy searching.

test scenario locally for #38408 and there are other similar

I will keep the issue open for now and look out for the builds
to see if there are any related failures.
This is related to #35975. We do not want a slow master to fail a

commit increases the master node timeout on this call to 30 mins.
Since introduction of data types that don't have a corresponding type
in ES the `esType` is error-prone when used for `unmappedType()` calls.
Moreover since the renaming of `DATE` to `DATETIME` and the introduction
of an actual date-only `DATE` the `esType` would return `datetime` which
is not a valid type for ES mapping.
Fixes: #38051
For some users, the built in authorization mechanism does not fit their
needs and no feature that we offer would allow them to control the
authorization process to meet their needs. In order to support this,
a concept of an AuthorizationEngine is being introduced, which can be
provided using the security extension mechanism.
An AuthorizationEngine is responsible for making the authorization
decisions about a request. The engine is responsible for knowing how to
authorize and can be backed by whatever mechanism a user wants. The
default mechanism is one backed by roles to provide the authorization
decisions. The AuthorizationEngine will be called by the
AuthorizationService, which handles more of the internal workings that
apply in general to authorization within Elasticsearch.
In order to support external authorization services that would back an
authorization engine, the entire authorization process has become
asynchronous, which also includes all calls to the AuthorizationEngine.
The use of roles also leaked out of the AuthorizationService in our
existing code that is not specifically related to roles so this also
needed to be addressed. RequestInterceptor instances sometimes used a
role to ensure a user was not attempting to escalate their privileges.
Addressing this leakage of roles meant that the RequestInterceptor
execution needed to move within the AuthorizationService and that
AuthorizationEngines needed to support detection of whether a user has
more privileges on a name than another. The second area where roles
leaked to the user is in the handling of a few privilege APIs that
could be used to retrieve the user's privileges or ask if a user has
privileges to perform an action. To remove the leakage of roles from
these actions, the AuthorizationService and AuthorizationEngine gained
methods that enabled an AuthorizationEngine to return the response for
these APIs.
Ultimately this feature is the work included in:

Elasticsearch has long [supported](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-versioning) compare and set (a.k.a optimistic concurrency control) operations using internal document versioning. Sadly that approach is flawed and can sometime do the wrong thing. Here's the relevant excerpt from the resiliency status page:
> When a primary has been partitioned away from the cluster there is a short period of time until it detects this. During that time it will continue indexing writes locally, thereby updating document versions. When it tries to replicate the operation, however, it will discover that it is partitioned away. It won’t acknowledge the write and will wait until the partition is resolved to negotiate with the master on how to proceed. The master will decide to either fail any replicas which failed to index the operations on the primary or tell the primary that it has to step down because a new primary has been chosen in the meantime. Since the old primary has already written documents, clients may already have read from the old primary before it shuts itself down. The version numbers of these reads may not be unique if the new primary has already accepted writes for the same document
We recently [introduced](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/optimistic-concurrency-control.html) a new sequence number based approach that doesn't suffer from this dirty reads problem.
This commit removes support for internal versioning as a concurrency control mechanism in favor of the sequence number approach.
Relates to #1078
Currently the snapshot/restore process manually sets the global
checkpoint to the max sequence number from the restored segements. This
does not work for Ccr as this will lead to documents that would be
recovered in the normal followering operation from being recovered.
This commit fixes this issue by setting the initial global checkpoint to
the existing local checkpoint.
`CreateIndexRequest#source(Map<String, Object>, ... )`, which is used when
deserializing index creation requests, accidentally accepts mappings that are
nested twice under the type key (as described in the bug report #38266).
This in turn causes us to be too lenient in parsing typeless mappings. In
particular, we accept the following index creation request, even though it
should not contain the type key `_doc`:
```
PUT index?include_type_name=false
{
"mappings": {
"_doc": {
"properties": { ... }
}
}
}
```
There is a similar issue for both 'put templates' and 'put mappings' requests
as well.
This PR makes the minimal changes to detect and reject these typed mappings in
requests. It does not address #38266 generally, or attempt a larger refactor
around types in these server-side requests, as I think this should be done at a
later time.
The backport of #38022 introduced types-deprecation warning for get/put template requests
that cause problems on tests master in mixed cluster scenarios. While these warnings are
caught and ignored in regular Rest tests, the get template requests in XPackRestTestHelper
were missed.
Closes#38412
Tests can override assertToXContentEquivalence() in case their xcontent
cannot be directly compared (e.g. due to insertion order in maps
affecting the xcontent ordering). But the `testHlrcFromXContent` test

`assertToXContentEquivalence()`
Fixes#36034
With this change we no longer support pluggable discovery implementations. No
known implementations of `DiscoveryPlugin` actually override this method, so in
practice this should have no effect on the wider world. However, we were using
this rather extensively in tests to provide the `test-zen` discovery type. We
no longer need a separate discovery type for tests as we no longer need to
customise its behaviour.

Introduced FollowParameters class that put follow, resume follow,
put auto follow pattern requests and follow info response classes reuse.
The FollowParameters class had the fields, getters etc. for the common parameters
that all these APIs have. Also binary and xcontent serialization /
parsing is handled by this class.
The follow, resume follow, put auto follow pattern request classes originally
used optional non primitive fields, so FollowParameters has that too and the follow info api can handle that now too.
Also the followerIndex field can in production only be specified via
the url path. If it is also specified via the request body then
it must have the same value as is specified in the url path. This
option only existed to xcontent testing. However the AbstractSerializingTestCase
base class now also supports createXContextTestInstance() to provide
a different test instance when testing xcontent, so allowing followerIndex
to be specified via the request body is no longer needed.
By moving the followerIndex field from Body to ResumeFollowAction.Request
class and not allowing the followerIndex field to be specified via
the request body the Body class is redundant and can be removed. The
ResumeFollowAction.Request class can then directly use the
FollowParameters class.
For consistency I also removed the ability to specified followerIndex
in the put follow api and the name in put auto follow pattern api via
the request body.

which is the settings configuration parameter for `InternalTestCluster`s.
The real problem, that had created tests failures like #31028 and #32685, is
that the check `licenseState.isAuthAllowed()` can change sporadically. If it were
to return `true` or `false` during the whole test there would be no problem.
The problem manifests when it turns from `true` to `false` right before `Realms.asList()`.
There are other license checks before this one (request filter, token service, etc)
that would not cause a problem if they would suddenly see the check as `false`.
But switching to `false` before `Realms.asList()` makes it appear that no installed
realms could have handled the authn token which is an authentication error, as can
be seen in the failing tests.
Closes#31028#32685
Renames the following settings to remove the mention of `zen` in their names:
- `discovery.zen.hosts_provider` -> `discovery.seed_providers`
- `discovery.zen.ping.unicast.concurrent_connects` -> `discovery.seed_resolver.max_concurrent_resolvers`
- `discovery.zen.ping.unicast.hosts.resolve_timeout` -> `discovery.seed_resolver.timeout`
- `discovery.zen.ping.unicast.hosts` -> `discovery.seed_addresses`

X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.
This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.
The API keys:-
- by default do not have an expiration but expiration can be
configured where the API keys need to be expired after a
certain amount of time.
- when generated will keep authentication information of the user that
generated them.
- can be defined with a role describing the privileges for accessing
Elasticsearch and will be limited by the role of the user that
generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
before being deleted. The expired API keys remover task handles this.
Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`
The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```
Closes#34383
We mention in our documentation for the token
expiration configuration maximum value is 1 hour
but do not enforce it. This commit adds max limit
to the TOKEN_EXPIRATION setting.
This test should not pass until CCR finishes integrating shard history
retention leases. It currently sometimes passes (which is a bug in the
test), but cannot pass reliably until the linked issue is resolved.
There are two issues regarding the way that we sync mapping from leader
to follower when a ccr restore is completed:
1. The returned mapping from a cluster service might not be up to date
as the mapping of the restored index commit.
2. We should not compare the mapping version of the follower and the
leader. They are not related to one another.
Moreover, I think we should only ensure that once the restore is done,
the mapping on the follower should be at least the mapping of the copied
index commit. We don't have to sync the mapping which is updated after
we have opened a session.

This is related to #35975. Currently when an index falls behind a leader
it encounters a fatal exception. This commit adds a test for that
scenario. Additionally, it tests that the user can stop following, close
the follower index, and put follow again. After the indexing is
re-bootstrapped, it will recover the documents it lost in normal
following operations.
This commit fixes the pinning of SSLContexts to TLSv1.2 in the
SSLConfigurationReloaderTests. The pinning was added for the initial
creation of clients and webservers but the updated contexts would
default to TLSv1.3, which is known to cause hangs with the
MockWebServer that we use.

This PR removes the use of document types from the monitoring exporters and template + watches setup code.
It does not remove the notion of types from the monitoring bulk API endpoint "front end" code as that code will eventually just go away in 8.0 and be replaced with Beats as collectors/shippers directly to the monitoring cluster.
At times, we need to check for usage of deprecated settings in settings
which should not be returned by the NodeInfo API. This commit changes
the deprecation info API to run all node checks locally so that these
settings can be checked without exposing them via any externally
accessible API.
This commit introduces a background sync for retention leases. The idea
here is that we do a heavyweight sync when adding a new retention lease,
and then periodically we want to background sync any retention lease
renewals to the replicas. As long as the background sync interval is
significantly lower than the extended lifetime of a retention lease, it
is okay if from time to time a replica misses a sync (it will still have
an older version of the lease that is retaining more data as we assume
that renewals do not decrease the retaining sequence number). There are
two follow-ups that will come after this commit. The first is to address
the fact that we have not adapted the should periodically flush logic to
possibly flush the retention leases. We want to do something like flush
if we have not flushed in the last five minutes and there are renewed
retention leases since the last time that we flushed. An additional
follow-up will remove the syncing of retention leases when a retention
lease expires. Today this sync could be invoked in the background by a
merge operation. Rather, we will move the syncing of retention lease
expiration to be done under the background sync. The background sync
will use the heavyweight sync (write action) if a lease has expired, and
will use the lightweight background sync (replication action) otherwise.
The explanation so far can be invaluable for troubleshooting
as incorrect decisions made early on in the structure analysis
can result in seemingly crazy decisions or timeouts later on.
