Adds the ability to fetch chunks from different files in parallel, configurable using the new `ccr.indices.recovery.max_concurrent_file_chunks` setting, which defaults to 5 in this PR.
The implementation uses the parallel file writer functionality that is also used by peer recoveries.
Improve verifier to disallow grouping over grouping functions (e.g.
HISTOGRAM over HISTOGRAM).

In #38333 and #38350 we moved away from the `discovery.zen` settings namespace
since these settings have an effect even though Zen Discovery itself is being
phased out. This change aligns the documentation and the names of related
classes and methods with the newly-introduced naming conventions.
Aliases defined in SELECT (Project or Aggregate) are now resolved in the
following WHERE clause. The Analyzer has been enhanced to identify this
rule and replace the field accordingly.
Close#29983
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.
I have not been able to reproduce the failing
test scenario locally for #38408 and there are other similar
tests which are running fine in the same test class.
I am re-enabling the test with additional logs so
that we can debug further on what's happening.
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
recovery from remote process due to a slow put mappings call. This
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
hardcoded the equivalence test to `true` instead of consulting
`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.

the clock resolution changed from jdk8->jdk10, hence the test is passing
in jdk8 but failing in jdk10. The Watcher's objects are serialised and
deserialised with milliseconds precision, making test to fail in jdk 10
and higher

The test is now expected to be always passing no matter what the random
locale is. This is fixed with using jdk ZoneId.systemDefault() in both
the test and CronEvalTool

If a job cannot be assigned to a node because an index it
requires is unavailable and there are lazy ML nodes then
index unavailable should be reported as the assignment
explanation rather than waiting for a lazy ML node.
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.
Authn is enabled only if `license_type` is non `basic`, but `basic` is
what the `LicenseService` generates implicitly. This commit explicitly sets
license type to `trial`, which allows for authn, in the `SecuritySettingsSource`
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

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.
Relates #36879Closes#37887
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.

Today the following settings in the `discovery.zen` namespace are still used:
- `discovery.zen.no_master_block`
- `discovery.zen.hosts_provider`
- `discovery.zen.ping.unicast.concurrent_connects`
- `discovery.zen.ping.unicast.hosts.resolve_timeout`
- `discovery.zen.ping.unicast.hosts`
This commit deprecates all other settings in this namespace so that they can be
removed in the next major version.
It would be beneficial to apply some of the request interceptors even
when features are disabled. This change reworks the way we build that
list so that the interceptors we always want to use are constructed
outside of the settings check.
Instead of throwing an exception, use an unresolved attribute to pass
the message to the Verifier.
Additionally improve the parser to save the extended source for the

The culprit in #38097 is an `IndicesRequest` that has no indices,
but instead of `request.indices()` returning `null` or `String[0]`
it returned `String[] {null}` . This tripped the audit filter.
I have addressed this in two ways:
1. `request.indices()` returning `String[] {null}` is treated as `null`
or `String[0]`, i.e. no indices
2. `null` values among the roles and indices lists, which are
unexpected, will never again stumble the audit filter; `null` values
are treated as special values that will not match any policy,
i.e. their events will always be printed.
Closes#38097
* Add checks for Grouping functions restriction to be placed inside GROUP BY
* Fixed bug where GROUP BY HISTOGRAM (not using alias) wasn't recognized

Adds a Step to the Shrink and Delete actions which prevents those
actions from running on a leader index - all follower indices must first
unfollow the leader index before these actions can run. This prevents
the loss of history before follower indices are ready, which might
otherwise result in the loss of data.
Introduce client-side sorting of groups based on aggregate
functions. To allow this, the Analyzer has been extended to push down
to underlying Aggregate, aggregate function and the Querier has been
extended to identify the case and consume the results in order and sort
them based on the given columns.
The underlying QueryContainer has been slightly modified to allow a view
of the underlying values being extracted as the columns used for sorting
might not be requested by the user.
The PR also adds minor tweaks, mainly related to tree output.
Close#35118
Because concurrent sync requests from a primary to its replicas could be
in flight, it can be the case that an older retention leases collection
arrives and is processed on the replica after a newer retention leases
collection has arrived and been processed. Without a defense, in this
case the replica would overwrite the newer retention leases with the
older retention leases. This commit addresses this issue by introducing
a versioning scheme to retention leases. This versioning scheme is used
to resolve out-of-order processing on the replica. We persist this
version into Lucene and restore it on recovery. The encoding of
retention leases is starting to get a little ugly. We can consider
addressing this in a follow-up.
There was a bug where creating a new policy would start

This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.
Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.
Unlike assertBusy, awaitBusy does not retry if the code-block throws an
AssertionError. A refresh in atLeastDocsIndexed can fail because we call
this method while we are closing some node in FollowerFailOverIT.
This PR adds the `monitor/xpack/info` cluster-level privilege to the built-in `monitoring_user` role.
This privilege is required for the Monitoring UI to call the `GET _xpack API` on the Monitoring Cluster. It needs to do this in order to determine the license of the Monitoring Cluster, which further determines whether Cluster Alerts are shown to the user or not.
Resolves#37970.
In 7.x Java timestamp formats are the default timestamp format and
there is no need to prefix them with "8". (The "8" prefix was used
in 6.7 to distinguish Java timestamp formats from Joda timestamp
formats.)
This change removes the "8" prefixes from timestamp formats in the
output of the ML file structure finder.
This commit enables the use of TLSv1.3 with security by enabling us to
properly map `TLSv1.3` in the supported protocols setting to the
algorithm for a SSLContext. Additionally, we also enable TLSv1.3 by
default on JDKs that support it.
An issue was uncovered with the MockWebServer when TLSv1.3 is used that
ultimately winds up in an endless loop when the client does not trust
the server's certificate. Due to this, SSLConfigurationReloaderTests
has been pinned to TLSv1.2.
Closes#32276
In 6.3 trial licenses were changed to default to security
disabled, and ee added some heuristics to detect when security should

This change removes those heuristics, and requires that security be
explicitly enabled (via the `xpack.security.enabled` setting) for
trial licenses.

Currently we use the raw byte array length when calling the IndexInput
read call to determine how many bytes we want to read. However, due to
how BigArrays works, the array length might be longer than the reference
length. This commit fixes the issue and uses the BytesRef length when
calling read. Additionally, it expands the index follow test to index
many more documents. These documents should potentially lead to large
enough segment files to trigger scenarios where this fix matters.
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
FIRST and LAST can be used with one argument and work similarly to MIN
and MAX but they are implemented using a Top Hits aggregation and
therefore can also operate on keyword fields. When a second argument is
provided then they return the first/last value of the first arg when its
values are ordered ascending/descending (respectively) by the values of
the second argument. Currently because of the usage of a Top Hits
aggregation FIRST and LAST cannot be used in the HAVING clause of a
GROUP BY query to filter on the results of the aggregation.

The existing implementation was slow due to exceptions being thrown if

Previously, ShrinkAction would fail if
it was executed on an index that had
the same number of shards as the target
shrunken number.
This PR introduced a new BranchingStep that
is used inside of ShrinkAction to branch which
step to move to next, depending on the
shard values. So no shrink will occur if the
shard count is unchanged.
This commit allows implementors of the `HandledTransportAction` to
specify what thread the action should be executed on. The motivation for
this commit is that certain CCR requests should be performed on the
generic threadpool.
The apache commons http client implementations recently released
versions that solve TLS compatibility issues with the new TLS engine
that supports TLSv1.3 with JDK 11. This change updates our code to
use these versions since JDK 11 is a supported JDK and we should
allow the use of TLSv1.3.
This fixes#38027. Currently we assert that all shards have failed.
However, it is possible that some shards do not have segement files
created yet. The action that we block is fetching these segement files
so it is possible that some shards successfully recover.
This commit changes the assertion to ensure that at least some of the
shards have failed.
Today we pass `discovery.zen.minimum_master_nodes` to nodes started up in
tests, but for 7.x nodes this setting is not required as it has no effect.
This commit removes this setting so that nodes are started with more realistic
configurations, and deprecates it.
Doc-value fields now return a value that is based on the mappings rather than
the script implementation by default.
This deprecates the special `use_field_mapping` docvalue format which was added
in #29639 only to ease the transition to 7.x and it is not necessary anymore in
7.0.
The certgen, certutil and saml-metadata tools did not correctly return

These commands now explicitly exit with the code that was returned

This commit fixes a potential race in the IndexFollowingIT. Currently it
is possible that we fetch the task metadata, it is null, and that throws
a null pointer exception. Assertbusy does not catch null pointer
exceptions. This commit assertions that the metadata is not null.
This is related to #35975. It adds a action timeout setting that allows
timeouts to be applied to the individual transport actions that are
used during a ccr recovery.
Restricted indices (currently only .security-6 and .security) are special
internal indices that require setting the `allow_restricted_indices` flag
on every index permission that covers them. If this flag is `false`
(default) the permission will not cover these and actions against them
will not be authorized.
However, the monitoring APIs were the only exception to this rule.
This exception is herein forfeited and index monitoring privileges have to be
granted explicitly, using the `allow_restricted_indices` flag on the permission,
as is the case for any other index privilege.
This commit modifies the put follow index action to use a
CcrRepository when creating a follower index. It routes
the logic through the snapshot/restore process. A
wait_for_active_shards parameter can be used to configure
how long to wait before returning the response.
This change adds a _meta field storing the version in which
the index mappings were last updated to the 3 ML indices
that didn't previously have one:
- .ml-annotations
- .ml-meta
- .ml-notifications
All other ML indices already had such a _meta field.
This field will be useful if we ever need to automatically
update the index mappings during a future upgrade.

This commit changes the TransportVerifyShardBeforeCloseAction so that it issues a
forced flush, forcing the translog and the Lucene commit to contain the same max seq
number and global checkpoint in the case the Translog contains operations that were
not written in the IndexWriter (like a Delete that touches a non existing doc). This way
the assertion added in #37426 won't trip.

This commit moves the auditing of job deletion related errors
to the final listener in the job delete action. This ensures
any error that occurs during job deletion is audited.
In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine.
To populate additional fields node.id and cluster.uuid which are not available at start time,
a cluster state update will have to be received and the values passed to log4j pattern converter.
A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter.
Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace
see ESJsonLayout.java for more details and field descriptions

We inject an Unfollow action before Shrink because the Shrink action
cannot be safely used on a following index, as it may not be fully
caught up with the leader index before the "original" following index is
deleted and replaced with a non-following Shrunken index. The Unfollow
action will verify that 1) the index is marked as "complete", and 2) all
operations up to this point have been replicated from the leader to the
follower before explicitly disconnecting the follower from the leader.
Injecting an Unfollow action before the Rollover action is done mainly
as a convenience: This allow users to use the same lifecycle policy on
both the leader and follower cluster without having to explictly modify
the policy to unfollow the index, while doing what we expect users to
want in most cases.
If the index request is executed before the mapping update is applied on
the IndexShard, the index request will perform a dynamic mapping update.
This mapping update will be timeout (i.e, ProcessClusterEventTimeoutException)
because the latch is not open. This leads to the failure of the index
request and the test. This commit makes sure the mapping is ready
before we execute the index request.

We have read and write aliases for the ML results indices. However,
the job still had methods that purported to reliably return the name
of the concrete results index being used by the job. After reindexing
prior to upgrade to 7.x this will be wrong, so the method has been
renamed and the comments made more explicit to say the returned index
name may not be the actual concrete index name for the lifetime of the
job. Additionally, the selection of indices when deleting the job
has been changed so that it works regardless of concrete index names.
All these changes are nice-to-have for 6.7 and 7.0, but will become
critical if we add rolling results indices in the 7.x release stream
as 6.7 and 7.0 nodes may have to operate in a mixed version cluster
that includes a version that can roll results indices.

This commit introduces the `create_snapshot` cluster privilege and
the `snapshot_user` role.
This role is to be used by "cronable" tools that call the snapshot API
periodically without recurring to the `manage` cluster privilege. The
`create_snapshot` cluster privilege is much more limited compared to
the `manage` privilege.
The `snapshot_user` role grants the privileges to view the metadata of
all indices (including restricted ones, i.e. .security). It obviously grants the
create snapshot privilege but the repository has to be created using another
role. In addition, it grants the privileges to (only) GET repositories and
snapshots, but not create and delete them.
The role does not allow to create repositories. This distinction is important
because snapshotting equates to the `read` index privilege if the user has
control of the snapshot destination, but this is not the case in this instance,
because the role does not grant control over repository configuration.
This commit introduces retention lease syncing from the primary to its

The ML file structure finder has always reported both Joda

become the default in Elasticsearch.
This commit also removes direct imports of Joda classes in the
structure finder unit tests. Instead the core Joda BWC class
is used.

The TransportUnfollowAction updates the index settings but does not
increase the settings version to reflect that change.
This issue has been caught while working on the replication of closed
indices (#33888). The IndexFollowingIT.testUnfollowIndex() started to
fail and this specific assertion tripped. It does not happen on master
branch today because index metadata for closed indices are never
updated in IndexService instances, but this is something that is going
to change with the replication of closed indices.
The unlucky timing can cause this test to fail when the indexing is triggered from `maybeTriggerAsyncJob`. As this is asynchronous, in can finish quicker then the test stepping over to next assertion
The introduced barrier solves the problem

* Remove empty statements

When upgrading from 5.4 to 5.5 to 6.7 (inclusive) it was
necessary to ensure there was a mapping for type "doc" on
the ML state index before opening a job. This was because
5.4 created a multi-type ML state index.
In version 7.x we can be sure that any such 5.4 index is no
longer in use. It would have had to be reindexed into the
6.x index format prior to the upgrade to version 7.x.
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

When an index is frozen, two index settings are updated (index.frozen and

When the arguements of PERCENTILE and PERCENTILE_RANK can be folded,
the `ConstantFolding` rule kicks in and calls the `replaceChildren()`

as the logic of creating a new `InnerAggregate` instance from a list of
`Expression`s resides in the Optimizer. So, instead, `ConstantFolding`
should be applied before any of the aggregations related rules.

When we can't map the principal attribute from the configured SAML
attribute in the realm settings, we can't complete the

we present them with a list of attributes we did get from the SAML

list. This list will never contain the NameIDs though as they are
not part of the SAMLAttribute list. So we might have a NameID but
just with a different format.
This commit removes the Index Audit Output type, following its deprecation
in 6.7 by 8765a31d4e6770. It also adds the migration notice (settings notice).
In general, the problem with the index audit output is that event indexing
can be slower than the rate with which audit events are generated,
especially during the daily rollovers or the rolling cluster upgrades.
In this situation audit events will be lost which is a terrible failure situation
for an audit system.
Besides of the settings under the `xpack.security.audit.index` namespace, the
`xpack.security.audit.outputs` setting has also been deprecated and will be
removed in 7. Although explicitly configuring the logfile output does not touch
any deprecation bits, this setting is made redundant in 7 so this PR deprecates
it as well.

Today we keep the mapping on the follower in sync with the leader's
using the mapping version from changes requests. There are two rare
cases where the mapping on the follower is not synced properly:
1. The returned mapping version (from ClusterService) is outdated than
the actual mapping. This happens because we expose the latest cluster
state in ClusterService after applying it to IndexService.
2. It's possible for the FollowTask to receive an outdated mapping than
the min_required_mapping. In that case, it should fetch the mapping
again; otherwise, the follower won't have the right mapping.

In some cases we only have a string collection instead of a string list
that we want to serialize out. We have a convenience method for writing
a list of strings, but no such method for writing a collection of
strings. Yet, a list of strings is a collection of strings, so we can
simply liberalize StreamOutput#writeStringList to be more generous in
the collections that it accepts and write out collections of strings
too. On the other side, we do not have a convenience method for reading
a list of strings. This commit addresses both of these issues.
* Use ILM for Watcher history deletion
This commit adds an index lifecycle policy for the `.watch-history-*` indices.
This policy is automatically used for all new watch history indices.
This does not yet remove the automatic cleanup that the monitoring plugin does
for the .watch-history indices, and it does not touch the
`xpack.watcher.history.cleaner_service.enabled` setting.

Some steps, such as steps that delete, close, or freeze an index, may fail due to a currently running snapshot of the index. In those cases, rather than move to the ERROR step, we should retry the step when the snapshot has completed.
This change adds an abstract step (`AsyncRetryDuringSnapshotActionStep`) that certain steps (like the ones I mentioned above) can extend that will automatically handle a situation where a snapshot is taking place. When a `SnapshotInProgressException` is received by the listener wrapper, a `ClusterStateObserver` listener is registered to wait until the snapshot has completed, re-running the ILM action when no snapshot is occurring.
This also adds integration tests for these scenarios (thanks to @talevy in #37552).

While tests migration from Zen1 to Zen2, we've encountered this test.
This test is organized as follows:
Starts the first cluster node.
Starts the second cluster node.
Checks that license is active.
Interesting fact that adding assertLicenseActive(true) between 1
and 2 also makes the test pass.
assertLicenseActive retrieves XPackLicenseState from the nodes
and checks that active flag is set. It's set to true even before
the cluster is initialized.
So this test does not make sense.
This adds a set of helper classes to determine if an agg "has a value".
This is needed because InternalAggs represent "empty" in different
manners according to convention. Some use `NaN`, `+/- Inf`, `0.0`, etc.
A user can pass the Internal agg type to one of these helper methods
and it will report if the agg contains a value or not, which allows the
user to differentiate "empty" from a real `NaN`.
These helpers are best-effort in some cases. For example, several
pipeline aggs share a single return class but use different conventions
to mark "empty", so the helper uses the loosest definition that applies
to all the aggs that use the class.
Sums in particular are unreliable. The InternalSum simply returns 0.0
if the agg is empty (which is correct, no values == sum of zero). But this
also means the helper cannot differentiate from "empty" and `+1 + -1`.
It looks like the output of FileUserPasswdStore.parseFile shouldn't be wrapped
into another map since its output can be null. Doing this wrapping after the null
check (which potentially raises an exception) instead.
Use PEM files for the key/cert for TLS on the http layer of the

Currently we create dedicated network threads for both the http and
transport implementations. Since these these threads should never
perform blocking operations, these threads could be shared. This commit
modifies the nio-transport to have 0 http workers be default. If the
default configs are used, this will cause the http transport to be run
on the transport worker threads. The http worker setting will still exist
in case the user would like to configure dedicated workers. Additionally,
this commmit deletes dedicated acceptor threads. We have never had these
for the netty transport and they can be added back if a need is
determined in the future.
The integ tests currently use the raw zip project name as the
distribution type. This commit simplifies this specification to be
"default" or "oss". Whether zip or tar is used should be an internal
implementation detail of the integ test setup, which can (in the future)
be platform specific.
This grants the capability to grant privileges over certain restricted
indices (.security and .security-6 at the moment).
It also removes the special status of the superuser role.
IndicesPermission.Group is extended by adding the `allow_restricted_indices`
boolean flag. By default the flag is false. When it is toggled, you acknowledge
that the indices under the scope of the permission group can cover the
restricted indices as well. Otherwise, by default, restricted indices are ignored
when granting privileges, thus rendering them hidden for authorization purposes.
This effectively adds a confirmation "check-box" for roles that might grant
privileges to restricted indices.
The "special status" of the superuser role has been removed and coded as
any other role:
```
new RoleDescriptor("superuser",
new String[] { "all" },
new RoleDescriptor.IndicesPrivileges[] {
RoleDescriptor.IndicesPrivileges.builder()
.indices("*")
.privileges("all")
.allowRestrictedIndices(true)
// this ----^
.build() },
new RoleDescriptor.ApplicationResourcePrivileges[] {
RoleDescriptor.ApplicationResourcePrivileges.builder()
.application("*")
.privileges("*")
.resources("*")
.build()
},
null, new String[] { "*" },
MetadataUtils.DEFAULT_RESERVED_METADATA,
Collections.emptyMap());
```
In the context of the Backup .security work, this allows the creation of a
"curator role" that would permit listing (get settings) for all indices
(including the restricted ones). That way the curator role would be able to
ist and snapshot all indices, but not read or restore any of them.

Removes all sensitive settings (passwords, auth tokens, urls, etc...) for
watcher notifications accounts. These settings were deprecated (and
herein removed) in favor of their secure sibling that is set inside the

is no longer a valid setting, and it is replaced by
`xpack.notification.email.account.<id>.smtp.secure_password`
The ML subproject of xpack has a cache for the cpp artifact snapshots
which is checked on each build. The cache is outside of the build dir so
that it is not wiped on a typical clean, as the artifacts can be large

wipe the cache dir, as over time the size of the directory can become
bloated.
Currently we add the CcrRestoreSourceService as a index event

Additionally, this commit moves session uuid generation to the leader
cluster. And renames the PutCcrRestoreSessionRequest to
StartCcrRestoreSessionRequest to reflect that change.

This change adds the unfollow action for CCR follower indices.
This is needed for the shrink action in case an index is a follower index.
This will give the follower index the opportunity to fully catch up with
the leader index, pause index following and unfollow the leader index.
After this the shrink action can safely perform the ilm shrink.
The unfollow action needs to be added to the hot phase and acts as
barrier for going to the next phase (warm or delete phases), so that
follower indices are being unfollowed properly before indices are expected
to go in read-only mode. This allows the force merge action to execute
its steps safely.
The unfollow action has three steps:
* `wait-for-indexing-complete` step: waits for the index in question
to get the `index.lifecycle.indexing_complete` setting be set to `true`
* `wait-for-follow-shard-tasks` step: waits for all the shard follow tasks
for the index being handled to report that the leader shard global checkpoint
is equal to the follower shard global checkpoint.
* `pause-follower-index` step: Pauses index following, necessary to unfollow
* `close-follower-index` step: Closes the index, necessary to unfollow
* `unfollow-follower-index` step: Actually unfollows the index using
the CCR Unfollow API
* `open-follower-index` step: Reopens the index now that it is a normal index
* `wait-for-yellow` step: Waits for primary shards to be allocated after
reopening the index to ensure the index is ready for the next step
In the case of the last two steps, if the index in being handled is
a regular index then the steps acts as a no-op.

This change fixes failures in the SslMultiPortTests where we attempt to

addresses and randomization will pick one of these addresses to

may not be the address we are actually connecting to. In order to
resolve this, the test now sets the bind host for profiles to the
loopback address and uses the same address for connecting.

Migrate ml job and datafeed config of open jobs and update
the parameters of the persistent tasks as they become unallocated
during a rolling upgrade. Block allocation of ml persistent tasks
until the configs are migrated.
Currently when there are no more auto follow patterns for a remote cluster then
the AutoFollower instance for this remote cluster will be removed. If
a new auto follow pattern for this remote cluster gets added quickly enough
after the last delete then there may be two AutoFollower instance running
for this remote cluster instead of one.
Each AutoFollower instance stops automatically after it sees in the
start() method that there are no more auto follow patterns for the
remote cluster it is tracking. However when an auto follow pattern
gets removed and then added back quickly enough then old AutoFollower
may never detect that at some point there were no auto follow patterns
for the remote cluster it is monitoring. The creation and removal of
an AutoFollower instance happens independently in the `updateAutoFollowers()`
as part of a cluster state update.
By adding the `removed` field, an AutoFollower instance will not miss the
fact there were no auto follow patterns at some point in time. The
`updateAutoFollowers()` method now marks an AutoFollower instance as
removed when it sees that there are no more patterns for a remote cluster.
The updateAutoFollowers() method can then safely start a new AutoFollower
instance.

The SourceOnlySnapshotIT class tests a source only repository
using the following scenario:
starts a master node
starts a data node
creates a source only repository
creates an index with documents
snapshots the index to the source only repository
deletes the index
stops the data node
starts a new data node
restores the index
Thanks to ESIntegTestCase the index is sometimes created using a custom
data path. With such a setting, when a shard is assigned to one of the data
node of the cluster the shard path is resolved using the index custom data
path and the node's lock id by the NodeEnvironment#resolveCustomLocation().
It should work nicely but in SourceOnlySnapshotIT.snashotAndRestore(), b
efore the change in this PR, the last data node was restarted using a different
path.home. At startup time this node was assigned a node lock based on other
locks in the data directory of this temporary path.home which is empty. So it
always got the 0 lock id. And when this new data node is assigned a shard for
the index and resolves it against the index custom data path, it also uses the
node lock id 0 which conflicts with another node of the cluster, resulting in
various errors with the most obvious one being LockObtainFailedException.
This commit removes the temporary home path for the last data node so that it
uses the same path home as other nodes of the cluster and then got assigned
a correct node lock id at startup.

* In REST tests, use include_type_name=true by default for index creation.
* Make sure to use 'expression == false'.
* Clarify the different IndexTemplateMetaData toXContent methods.
* Fix FullClusterRestartIT#testSnapshotRestore.
* Fix the ml_anomalies_default_mappings test.
* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.
We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.
* Make sure to use 'expression == false' in FullClusterRestartIT.
* Mention include_type_name in the REST templates docs.
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.
Closes#29797
This new `hostname` field is meant to be a replacement for its sibling `name` field. See https://github.com/elastic/beats/pull/9943, particularly https://github.com/elastic/beats/pull/9943#discussion_r245932581.
This PR simply adds the new field (`hostname`) to the mapping without removing the old one (`name`), because a user might be running an older-version Beat (without this field rename in it) with a newer-version Monitoring ES cluster (with this PR's change in it).
AFAICT the Monitoring UI isn't currently using the `name` field so no changes are necessary there yet. If it decides to start using the `name` field, it will also want to look at the value of the `hostname` field.
This is related to #35975. It implements a file based restore in the
CcrRepository. The restore transfers files from the leader cluster
to the follower cluster. It does not implement any advanced resiliency
features at the moment. Any request failure will end the restore.
Adds another field, named "request.method", to the structured logfile audit.
This field is present for all events associated with a REST request (not a
transport request) and the value is one of GET, POST, PUT, DELETE, OPTIONS,
HEAD, PATCH, TRACE and CONNECT.
Improve error messages by returning the original SQL statement
declaration instead of trying to reproduce it as the casing and
whitespaces are not preserved accurately leading to small
differences.

Since `full` can be common as a field name or part of a field name
(e.g.: `full.name` or `name.full`), it's nice if it's not a reserved
keyword of the grammar so a user can use it without resorting to quotes.

SqlPlugin cannot have more than one public constructor, so for the testing
purposes the `getLicenseState()` should be overriden.

When this message was first added the model debug config was
the only thing that could be updated, but now more aspects of
the config can be updated so the message needs to be more
general.
* ML: Updating .ml-state calls to be able to support > 1 index
* Matching bulk delete behavior with dbq
* Adjusting state name
* refreshing indices before search
* fixing line length

This is a reinforcement of #37227. It turns out that
persistent tasks are not made stale if the node they
were running on is restarted and the master node does
not notice this. The main scenario where this happens
is when minimum master nodes is the same as the number
of nodes in the cluster, so the cluster cannot elect a
master node when any node is restarted.
When an ML node restarts we need the datafeeds for any
jobs that were running on that node to not just wait
until the jobs are allocated, but to wait for the
autodetect process of the job to start up. In the case
of reassignment of the job persistent task this was
dealt with by the stale status test. But in the case
where a node restarts but its persistent tasks are not
reassigned we need a deeper test.
Fixes#36810
This adds a configurable whitelist to the HTTP client in watcher. By
default every URL is allowed to retain BWC. A dynamically configurable
setting named "xpack.http.whitelist" was added that allows to
configure an array of URLs, which can also contain simple regexes.
Closes#29937
Added warnings checks to existing tests
Added “defaultTypeIfNull” to DocWriteRequest interface so that Bulk requests can override a null choice of document type with any global custom choice.

This change ensures we always countdown the latch in the
SSLConfigurationReloaderTests to prevent the suite from timing out in
case of an exception. Additionally, we also increase the logging of the
resource watcher in case an IOException occurs.
See #36053
Field of types aliases that have dots in name are returned without a
hierarchy by field_caps, as oppose to the mapping api or field with
concrete types, which in turn breaks IndexResolver.
This commit fixes this by creating the backing hierarchy similar to the
mapping api.
