Due to missing stubbing for `NativePrivilegeStore#getPrivileges`
the test `testNegativeLookupsAreCached` failed
when the superuser role name was present in the role names.
This commit adds missing stubbing.
Closes: #37657
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
elasticsearch keystore. For example:
`xpack.notification.email.account.<id>.smtp.password`
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
and do not change often. This commit adds a cleanCache task which will
wipe the cache dir, as over time the size of the directory can become
bloated.
Currently we add the CcrRestoreSourceService as a index event
listener. However, if ccr is disabled, this service is null and we
attempt to add a null listener throwing an exception. This commit only
adds the listener if ccr is enabled.
This is related to #35975. This commit adds timeout functionality to
the local session on a leader node. When a session is started, a timeout
is scheduled using a repeatable runnable. If the session is not accessed
in between two runs the session is closed. When the sssion is closed,
the repeating task is cancelled.
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.

Commit #37535 removed an internal restore request in favor of the
RestoreSnapshotRequest. Commit #37449 added a new test that used the
internal restore request. This commit modifies the new test to use the
RestoreSnapshotRequest.
This is a continuation of #28667 and has as goal to convert all executors to propagate errors to the
uncaught exception handler. Notable missing ones were the direct executor and the scheduler. This
commit also makes it the property of the executor, not the runnable, to ensure this property. A big
part of this commit also consists of vastly improving the test coverage in this area.
This commit adds a set_priority action to the hot, warm, and cold

* SQL: Rename SQL data type DATE to DATETIME
SQL data type DATE has only the date part (e.g.: 2019-01-14)
without any time information. Previously the SQL type DATE was

with TZ information. To conform with SQL data types the data type
`DATE` is renamed to `DATETIME`, since it includes also the time,
as a new runtime SQL `DATE` data type will be introduced down the road,
which only contains the date part and meets the SQL standard.

This change fixes failures in the SslMultiPortTests where we attempt to
connect to a profile on a port it is listening on but the connection
fails. The failure is due to the profile being bound to multiple
addresses and randomization will pick one of these addresses to
determine the listening port. However, the address we get the port for
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.

This commit removes the fallback for SSL settings. While this may be

fallback to some other configuration.

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 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.

Jobs created in version 6.1 or earlier can have a
null model_memory_limit. If these are parsed from
cluster state following a full cluster restart then
we replace the null with 4096mb to make the meaning
explicit. But if such jobs are streamed from an
old node in a mixed version cluster this does not
happen. Therefore we need to account for the
possibility of a null model_memory_limit in the ML
memory tracker.

In order to test this change, I had to move specific assertions into a dedicated class and
disable assertions for that class in the rest qa module. I think that is the right trade off.
If a running shard follow task needs to be restarted and
the remote connection seeds have changed then
a shard follow task currently fails with a fatal error.
The change creates the remote client lazily and adjusts
the errors a shard follow task should retry.
This issue was found in test failures in the recently added
ccr rolling upgrade tests. The reason why this issue occurs
more frequently in the rolling upgrade test is because ccr
is setup in local mode (so remote connection seed will become stale) and
all nodes are restarted, which forces the shard follow tasks to get
restarted at some point during the test. Note that these tests
cannot be enabled yet, because this change will need to be backported
to 6.x first. (otherwise the issue still occurs on non upgraded nodes)
I also changed the RestartIndexFollowingIT to setup remote cluster
via persistent settings and to also restart the leader cluster. This
way what happens during the ccr rolling upgrade qa tests, also happens
in this test.

This commit fixes a race condition in a test introduced by #36900 that
verifies concurrent authentications get a result propagated from the
first thread that attempts to authenticate. Previously, a thread may
be in a state where it had not attempted to authenticate when the first
thread that authenticates finishes the authentication, which would
cause the test to fail as there would be an additional authentication
attempt. This change adds additional latches to ensure all threads have
attempted to authenticate before a result gets returned in the
thread that is performing authentication.
Closing a channel using TLS/SSL requires reading and writing a
CLOSE_NOTIFY message (for pre-1.3 TLS versions). Many implementations do
not actually send the CLOSE_NOTIFY message, which means we are depending
on the TCP close from the other side to ensure channels are closed. In
case there is an issue with this, we need a timeout. This commit adds a
timeout to the channel close process for TLS secured channels.
As part of this change, we need a timer service. We could use the
generic Elasticsearch timeout threadpool. However, it would be nice to
have a local to the nio event loop timer service dedicated to network needs. In
the future this service could support read timeouts, connect timeouts,
request timeouts, etc. This commit adds a basic priority queue backed
service. Since our timeout volume (channel closes) is very low, this
should be fine. However, this can be updated to something more efficient
in the future if needed (timer wheel). Everything being local to the event loop
thread makes the logic simple as no locking or synchronization is necessary.
We already had logic to stop datafeeds running against
jobs that were OPENING, but a job that relocates from
one node to another while OPENED stays OPENED, and this
could cause the datafeed to fail when it sent data to
the OPENED job on its new node before it had a
corresponding autodetect process.
This change extends the check to stop datafeeds running
when their job is OPENING _or_ stale (i.e. has not had
its status reset since relocating to a different node).

This bug was introduced in #36893 and had the effect that
execution would continue after calling onFailure on the the
listener in checkIfTokenIsValid in the case that the token is
expired. In a case of many consecutive requests this could lead to
the unwelcome side effect of an expired access token producing a
successful authentication response.
After #30794, our caching realms limit each principal to a single auth
attempt at a time. This prevents hammering of external servers but can
cause a significant performance hit when requests need to go through a
realm that takes a long time to attempt to authenticate in order to get
to the realm that actually authenticates. In order to address this,
this change will propagate failed results to listeners if they use the
same set of credentials that the authentication attempt used. This does
prevent these stalled requests from retrying the authentication attempt
but the implementation does allow for new requests to retry the
attempt.

This commit implements a straightforward approach to retention lease
expiration. Namely, we inspect which leases are expired when obtaining
the current leases through the replication tracker. At that moment, we
clean the map that persists the retention leases in memory.
Today, a setting can declare that its validity depends on the values of other
related settings. However, the validity of a setting is not always checked
against the correct values of its dependent settings because those settings'
correct values may not be available when the validator runs.
This commit separates the validation of a settings updates into two phases,
with separate methods on the `Setting.Validator` interface. In the first phase
the setting's validity is checked in isolation, and in the second phase it is
checked again against the values of its related settings. Most settings only
use the first phase, and only the few settings with dependencies make use of
the second phase.
This commit is the first in a series which will culminate with
fully-functional shard history retention leases.
Shard history retention leases are aimed at preventing shard history
consumers from having to fallback to expensive file copy operations if
shard history is not available from a certain point. These consumers
include following indices in cross-cluster replication, and local shard
recoveries. A future consumer will be the changes API.
Further, index lifecycle management requires coordinating with some of
these consumers otherwise it could remove the source before all
consumers have finished reading all operations. The notion of shard
history retention leases that we are introducing here will also be used
to address this problem.
Shard history retention leases are a property of the replication group
managed under the authority of the primary. A shard history retention
lease is a combination of an identifier, a retaining sequence number, a
timestamp indicating when the lease was acquired or renewed, and a
string indicating the source of the lease. Being leases they have a
limited lifespan that will expire if not renewed. The idea of these
leases is that all operations above the minimum of all retaining
sequence numbers will be retained during merges (which would otherwise
clear away operations that are soft deleted). These leases will be
periodically persisted to Lucene and restored during recovery, and
broadcast to replicas under certain circumstances.
This commit is merely putting the basics in place. This first commit
only introduces the concept and integrates their use with the soft
delete retention policy. We add some tests to demonstrate the basic
management is correct, and that the soft delete policy is correctly
influenced by the existence of any retention leases. We make no effort
in this commit to implement any of the following:
- timestamps
- expiration
- persistence to and recovery from Lucene
- handoff during primary relocation
- sharing retention leases with replicas
- exposing leases in shard-level statistics
- integration with cross-cluster replication
These will occur individually in follow-up commits.
This pull request changes the Freeze Index and Close Index actions so
that these actions always requires a Task. The task's id is then propagated
from the Freeze action to the Close action, and then to the Verify shard action.
This way it is possible to track which Freeze task initiates the closing of an index,
and which consecutive verifiy shard are executed for the index closing.
As suggested in #36775, this pull request renames the following methods:
ClusterBlocks.hasGlobalBlock(int)
ClusterBlocks.hasGlobalBlock(RestStatus)

Therefore, their nullable() implementation cannot return true. On
the other hand they cannot return false as if they're wrapped within
an IS NULL or IS NOT NULL expression, the expression will be folded
to false and true respectively leading to wrong results.

In Lucene 8 searches can skip non-competitive hits if the total hit count is not requested.
It is also possible to track the number of hits up to a certain threshold. This is a trade off to speed up searches while still being able to know a lower bound of the total hit count. This change adds the ability to set this threshold directly in the track_total_hits search option. A boolean value (true, false) indicates whether the total hit count should be tracked in the response. When set as an integer this option allows to compute a lower bound of the total hits while preserving the ability to skip non-competitive hits when enough matches have been collected.

If we don't explicitly sett the client SSLSocketFactory when
creating an InMemoryDirectoryServer and setting its SSL config, it
will result in using a TrustAllTrustManager(that extends
X509TrustManager) which is not allowed in a FIPS 140 JVM.
Instead, we get the SSLSocketFactory from the existing SSLContext
and pass that to be used.

The phrase "missing authentication token" is historic and is based
around the use of "AuthenticationToken" objects inside the Realm code.
However, now that we have a TokenService and token API, this message
would sometimes lead people in the wrong direction and they would try
and generate a "token" for authentication purposes when they would
typically just need a username:password Basic Auth header.
This change replaces the word "token" with "credentials".
In #30509 we changed the way SSL configuration is reloaded when the
content of a file changes. As a consequence of that implementation
change the LDAP realm ceased to pick up changes to CA files (or other
certificate material) if they changed.
This commit repairs the reloading behaviour for LDAP realms, and adds
a test for this functionality.

The AutoFollowCoordinator should be resilient to the fact that the follower
index has already been created and in that case it should only update
the auto follow metadata with the fact that the follower index was created.
Relates to #33007
Currently auto follow stats users are unable to see whether an auto follow
error was recent or old. The new timestamp field will help user distinguish
between old and new errors.
Both index following and auto following should be resilient against missing remote connections.
This happens in the case that they get accidentally removed by a user. When this happens
auto following and index following will retry to continue instead of failing with unrecoverable exceptions.
Both the put follow and put auto follow APIs validate whether the
remote cluster connection. The logic added in this change only exists
in case during the lifetime of a follower index or auto follow pattern
the remote connection gets removed. This retry behavior similar how CCR
deals with authorization errors.

Realm settings were changed in #30241 in a non-BWC way.
If you try and start a 7.x node using a 6.x config style, then the
default error messages do not adequately describe the cause of
the problem, or the solution.
This change detects the when realms are using the 6.x style and fails
with a specific error message.
This detection is a best-effort, and will detect issues when the
realms have not been modified to use the 7.x style, but may not detect
situations where the configuration was partially changed.
e.g. We can detect this:
xpack.security.authc:
realms.pki1.type: pki
realms.pki1.order: 3
realms.pki1.ssl.certificate_authorities: [ "ca.crt" ]
But this (where the "order" has been updated, but the "ssl.*" has not)
will fall back to the standard "unknown setting" check

... MlDistributedFailureIT.testLoseDedicatedMasterNode.
An intermittent failure has been observed in
`MlDistributedFailureIT. testLoseDedicatedMasterNode`.
The test launches a cluster comprised by a dedicated master node
and a data and ML node. It creates a job and datafeed and starts them.
It then shuts down and restarts the master node. Finally, the test asserts
that the two tasks have been reassigned within 10s.
The intermittent failure is due to the assertions that the tasks have been
reassigned failing. Investigating the failure revealed that the `assertBusy`
that performs that assertion times out. Furthermore, it appears that the
job task is not reassigned because the memory tracking info is stale.
Memory tracking info is refreshed asynchronously when a job is attempted
to be reassigned. Tasks are attempted to be reassigned either due to a relevant
cluster state change or periodically. The periodic interval is controlled by a cluster
setting called `cluster.persistent_tasks.allocation.recheck_interval` and defaults to 30s.
What seems to be happening in this test is that if all cluster state changes after the
master node is restarted come through before the async memory info refresh completes,
then the job might take up to 30s until it is attempted to reassigned. Thus the `assertBusy`
times out.
This commit changes the test to reduce the periodic check that reassigns persistent
tasks to `200ms`. If the above theory is correct, this should eradicate those failures.
Closes#36760

* This change is to account for different system clock implementations
or different Java versions (for Java 8, milliseconds precision is used;
for Java 9+ a system specific clock implementation is used which can
have greater precision than what we need here).
Negative timestamps are currently supported in joda time. These are
dates before epoch. However, it doesn't really make sense to have a
negative timestamp, since this is a modern format. Any dates before
epoch can be represented with normal date formats, like ISO8601.
Additionally, implementing negative epoch timestamp parsing in java time
has an edge case which would more than double the code required. This
commit deprecates use of negative epoch timestamps.

Leaving `index.lifecycle.indexing_complete` in place when removing the
lifecycle policy from an index can cause confusion, as if a new policy
is associated with the policy, rollover will be silently skipped.
Removing that setting when removing the policy from an index makes
associating a new policy with the index more involved, but allows ILM to
fail loudly, rather than silently skipping operations which the user may
assume are being performed.
* Adjust order of checks in WaitForRolloverReadyStep
This allows ILM to error out properly for indices that have a valid
alias, but are not the write index, while still handling
`indexing_complete` on old-style aliases and rollover (that is, those
which only point to a single index at a time with no explicit write
index)

The parser used for rollup configs in _meta fields was not able to
handle unrelated data in the meta field. If an unrelated object
was encountered, it would half-consume the JSON object, realize it

halfway consumed and the parsing framework would throw an exception.
This commit replaces the parsing logic with a set of minimal parsers,
each for the specific component we care about (`_doc`, `_meta`,
`_rollup`) and configured to ignore unknown fields where applicable.

This is related to #36652. In 7.0 we plan to deprecate a number of

leader responds to the request by telling the follower what files it
needs to fetch for a restore. This is not yet implemented.
Once, the restore is complete, the follower closes the session with the
DeleteCcrRestoreSessionAction action.

The remote connection info API leads to resolving addresses of seed

the modern world of cloud services with dynamically chaning
IPs. Instead, the remote connection info API should be providing the
configured seed nodes. This commit changes the remote connection info to
display the configured seed nodes, avoiding a hostname resolution. Note
that care was taken to preserve backwards compatibility with previous

indexing approach, simply set "type" : "geo_shape" in

following when using the new indexing approach:
* geo_shape query does not support querying by
MULTIPOINT.

This commit adds support to enable bulk upserts to use an index's
default pipeline. Bulk upsert, doc_as_upsert, and script_as_upsert
are all supported.
However, bulk script_as_upsert has slightly surprising behavior since
the pipeline is executed _before_ the script is evaluated. This means
that the pipeline only has access the data found in the upsert field
of the script_as_upsert. The non-bulk script_as_upsert (existing behavior)
runs the pipeline _after_ the script is executed. This commit
does _not_ attempt to consolidate the bulk and non-bulk behavior for
script_as_upsert.
This commit also adds additional testing for the non-bulk behavior,
which remains unchanged with this commit.

* Add raw sort values to SearchSortValues transport serialization (#36617)
In order for CCS alternate execution mode (see #32125) to be able to do the final reduction step on the CCS coordinating node, we need to serialize additional info in the transport layer as part of each `SearchHit`. Sort values are already present but they are formatted according to the provided `DocValueFormat` provided. The CCS node needs to be able to reconstruct the lucene `FieldDoc` to include in the `TopFieldDocs` and `CollapseTopFieldDocs` which will feed the `mergeTopDocs` method used to reduce multiple search responses (one per cluster) into one.
This commit adds such information to the `SearchSortValues` and exposes it through a new getter method added to `SearchHit` for retrieval. This info is only serialized at transport and never printed out at REST.
* Watcher: Ensure all internal search requests count hits (#36697)

* Ensure MapperService#getAllMetaFields elements order is deterministic (#36739)
MapperService#getAllMetaFields returns an array, which is created out of

ordering. The array returned by its toArray may be sorted differently
at each run. This caused some repeatability issues in our tests (see #29080)
as we pick random fields from the array of possible metadata fields,
but that won't be repeatable if the input array is sorted differently at
every run. Once setting the tests seed, hppc picks that up and the sorting is
deterministic, but failures don't repeat with the seed that gets printed out
originally (as a seed was not originally set).
See also https://issues.carrot2.org/projects/HPPC/issues/HPPC-173.
With this commit, we simply create a static sorted array that is used for
`getAllMetaFields`. The change is in production code but really affects
only testing as the only production usage of this method was to iterate
through all values when parsing fields in the high-level REST client code.
Anyways, this seems like a good change as returning an array would imply
that it's deterministically sorted.

This fixes two bugs about watcher notifications:
* registering accounts that had only secure settings was not possible before;
these accounts are very much practical for Slack and PagerDuty integrations.
* removes the limitation that, for an account with both secure and cluster settings,
the admin had to first change/add the secure settings and only then add the
dependent dynamic cluster settings. The reverse order would trigger a
SettingsException for an incomplete account.
The workaround is to lazily instantiate account objects, hoping that when accounts
are instantiated all the required settings are in place. Previously, the approach
was to greedily validate all the account settings by constructing the account objects,
even if they would not ever be used by actions. This made sense in a world where
all the settings were set by a single API. But given that accounts have dependent
settings (that must be used together) that have to be changed using different APIs
(POST _nodes/reload_secure_settings and PUT _cluster/settings), the settings group
would technically be in an invalid state in between the calls.
This fix builds account objects, and validates the settings, when they are
needed by actions.

few approaches. First, for normal transport settings, it usestransport.
instead of transport.tcp. Second, it uses transport.tcp, http.tcp,
or network.tcp for all settings that are proxies for OS level socket
settings. Third, it marks the network.tcp.connect_timeout setting for
removal. Network service level settings are only settings that apply to
both the http and transport modules. There is no connect timeout in
http. Fourth, it moves all the transport settings to a single class
TransportSettings similar to the HttpTransportSettings class.
This commit does not actually remove any settings. It just adds the new
renamed settings and adds todos for settings that will be deprecated.
* WaitForRolloverReadyStepTests#mutateInstance sometimes did not mutate the instance
correctly
* 40_explain_lifecycle#"Test new phase still has phase_time" is not really a necessary
integration test. In addition to this, it is flaky due to the asynchronous nature of
ILM metadata population
Introduce Histogram grouping function for bucketing/grouping data based
on a given range. Both date and numeric histograms are supported using
the appropriate range declaration (numbers vs intervals).
SELECT HISTOGRAM(number, 50) AS h FROM index GROUP BY h
SELECT HISTOGRAM(date, INTERVAL 1 YEAR) AS h FROM index GROUP BY h
In addition add multiply operator for Intervals
Add docs for intervals and histogram
Fix#36509
Add CURRENT_TIMESTAMP as keyword as well function alongside NOW()
These return the current date/time for the given query, computed when
the statement reaches the server. For completeness, CURRENT_TIMESTAMP
also accepts precision as an optional parameter.
Fix#36534
Add missing `formatTemplate()` for conditional functions which
resulted in incomplete painless script. Moreover the specific
return type of Object in the painless signatures resulted in
casting exceptions when conditional functions are used in the
ORDER BY.
Fixes: #36631
* Enable parallel restore operations
* Add uuid to restore in progress entries to uniquely identify them
* Adjust restore in progress entries to be a map in cluster state
* Added tests for:
* Parallel restore from two different snapshots
* Parallel restore from a single snapshot to different indices to test uuid identifiers are correctly used by `RestoreService` and routing allocator
* Parallel restore with waiting for completion to test transport actions correctly use uuid identifiers
