This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

This is a follow-up to #36086. It renames the internal repository

Additionally, this PR stops casting Client to NodeClient. The client we

The hard coded interval will be removed in a follow up change to make

The x-pack user and roles APIs aren't available unless security is enabled, so the tool should always be called with the -u and -p options specified.
This commit adds an empty CcrRepository snapshot/restore repository.
When a new cluster is registered in the remote cluster settings, a new
CcrRepository is registered for that cluster.
This is implemented using a new concept of "internal repositories".
RepositoryPlugin now allows implementations to return factories for
"internal repositories". The "internal repositories" are different from
normal repositories in that they cannot be registered through the
external repository api. Additionally, "internal repositories" are local
to a node and are not stored in the cluster state.
The repository will be unregistered if the remote cluster is removed.
This commit makes `document`, `update`, `explain`, `termvectors` and `mapping`
typeless APIs work on indices that have a type whose name is not `_doc`.
Unfortunately, this needs to be a bit of a hack since I didn't want calls with
random type names to see documents with the type name that the user had chosen
upon type creation.
The `explain` and `termvectors` do not support being called without a type for
now so the test is just using `_doc` as a type for now, we will need to fix
tests later but this shouldn't require further changes server-side since passing
`_doc` as a type name is what typeless APIs do internally anyway.

It is important that all shards of a given index have the same
`indexCreatedVersionMajor` to Lucene, or eg. merging those shards is going to
be considered illegal. At the moment, we use the latest Lucene version when
creating a shard, which could cause shards to have different created versions
eg. in case of forced allocation. This commit makes sure to reuse the
appropriate Lucene version in order to avoid such issues.

AutoFollowCoordinator should take into account that after auto following

When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.

The problem showed up on debian 8 which uses aufs docker storage

aufs does not support acls and thus the failure.

Introduces a debug log message when a bind fails and a trace message
when a bind succeeds.
It may seem strange to only debug a bind failure, but failures of this
nature are relatively common in some realm configurations (e.g. LDAP
realm with multiple user templates, or additional realms configured
after an LDAP realm).
This is a follow-up to #35144. That commit made the underlying
connection opening process in TcpTransport asynchronous. However the
method still blocked on the process being complete before returning.
This commit moves the blocking to the ConnectionManager level. This is
another step towards the top-level TransportService api being async.
This change adds the support for rest_total_hits_as_int
in the watcher search inputs. Setting this parameter in the request
will transform the search response to contain the total hits as
a number (instead of an object).
Note that this parameter is currently a noop since #35849 is not
merged.

The NotificationService (base class for SlackService, HipchatService ...) has both dynamic
cluster settings and SecureSettings and builds the clients (Account) that are used to comm
with external services. This commit fixes an important bug about updating/reloading any
of these settings (both Secure and dynamic cluster). Briefly the bug is due to the fact that
both the secure settings as well as the dynamic node scoped ones can be updated
independently, but when constructing the clients some of the settings might not be visible.
In the current implementation, there is a time between the
ShrinkStep and the ShrinkSetAliasStep that both the source and
target indices will be present with the same aliases. This means
that queries to during this time will query both and return
duplicates. This fixes that scenario by moving the alias inheritance
to the same aliases update request as is done in ShrinkSetAliasStep
This commit improves the efficiency of exact index name matching by
separating exact matches from those that include wildcards or regular
expressions. Internally, exact matching is done using a HashSet instead
of adding the exact matches to the automata. For the wildcard and
regular expression matches, the underlying implementation has not
changed.
The support for rest_total_hits_as_int has already been merged to 6x
in #35848 so this change adds this new option to master. The plan was
to add this new option as part of #35848 but we've decided to wait a few
days before merging this breaking change so this commit just handles
the new option as a noop exactly like 6x for now. This will allow
users to migrate to this parameter before #35848 is merged.

This is related to #34405 and a follow-up to #34753. It makes a number
of changes to our current keepalive pings.
The ping interval configuration is moved to the ConnectionProfile.
The server channel now responds to pings. This makes the keepalive
pings bidirectional.
On the client-side, the pings can now be optimized away. What this
means is that if the channel has received a message or sent a message
since the last pinging round, the ping is not sent for this round.
Some times the test fixtures plugin did not correctly disable tasks
from the build plugin as it should.
The plugin manager and tasks both use domain name collections so
the previus conde should have worked.
I did not have trime to track it down, but suspect there's some race
condition in Gradle causing this. The plugin manager is still incubating.
Since the tasks are on the cp even if the plugin is not applyed, we
don't really need to involve the plugin at all.

Right now using the `GET /_tasks/<taskid>` API and causing a task to opt
in to saving its result after being completed requires permissions on
the `.tasks` index. When we built this we thought that that was fine,
but we've since moved towards not leaking details like "persisting task
results after the task is completed is done by saving them into an index
named `.tasks`." A more modern way of doing this would be to save the
tasks into the index "under the hood" and to have APIs to manage the
saved tasks. This is the first step down that road: it drops the
requirement to have permissions to interact with the `.tasks` index when
fetching task statuses and when persisting statuses beyond the lifetime
of the task.
In particular, this moves the concept of the "origin" of an action into
a more prominent place in the Elasticsearch server. The origin of an
action is ignored by the server, but the security plugin uses the origin
to make requests on behalf of a user in such a way that the user need
not have permissions to perform these actions. It *can* be made to be
fairly precise. More specifically, we can create an internal user just
for the tasks API that just has permission to interact with the `.tasks`
index. This change doesn't do that, instead, it uses the ubiquitus
"xpack" user which has most permissions because it is simpler. Adding
the tasks user is something I'd like to get to in a follow up change.
Instead, the majority of this change is about moving the "origin"
concept from the security portion of x-pack into the server. This should
allow any code to use the origin. To keep the change managable I've also
opted to deprecate rather than remove the "origin" helpers in the
security code. Removing them is almost entirely mechanical and I'd like
to that in a follow up as well.

This changes the exporter code -- most notably the `http` exporter --
to use async operations throughout the resource management and bulk
initialization code (the bulk indexing of monitoring documents was
already async).
As part of this change, this does change one semi-core aspect of the
`HttpResource` class in that it will no longer block all concurrent calls
until the first call completes with
`HttpResource::checkAndPublishIfDirty`.
Now, any parallel attempts to check the resources will be skipped until
the first call completes (success or failure). While this is a technical
change, it has very little practical impact because the existing behavior
was either quick success (then every blocked request processed) or
each request timed out and failed anyway, thus being effectively
skipped (and a burden on the system).
step times were set. The assumption was that these are always set.
Tests passed, which led me to believe this was true. There is a time

The trigger engine did always create a new schedule data structure, when
the watcher indexing listener called an add. However the indexing
listener also called add, when the watch status was updated. This means,
that upon a watch status update the watch got retriggered, potentially
waiting a defined interval from the watch status update onwards, instead
of waiting from the last run.
This commit only updates the schedule in the trigger engine, if it
actually has changed, otherwise the existing schedule will not be
touched. This has two results
1. If a watch is updated by an execution, the existing interval will not
be touched (meaning the scheduled time will not move forward).
2. If a watch is updated by a user, but the schedule is not changed, it
will not be reset from the update (for example starting to count from 5
minutes again, if the interval was set to 5 minutes).
Furthermore some minor cleanups were applied, making variables final in

This commit adds a test for handling correctly all they possible
`SamlPrepareAuthenticationRequest` parameter combinations that
we might get from Kibana or a custom web application talking to the
SAML APIs.
We can match the correct SAML realm based either on the realm name
or the ACS URL. If both are included in the request then both need to
match the realm configuration.
This generates a synthesized "id" for each incoming request that is
included in the audit logs (file only).
This id can be used to correlate events for the same request (e.g.
authentication success with access granted).
This request.id is specific to the audit logs and is not used for any
other purpose
The request.id is consistent across nodes if a single request requires
execution on multiple nodes (e.g. search acros multiple shards).
When assertions are enabled, a Put User action that have no effect (a
noop update) would trigger an assertion failure and shutdown the node.
This change accepts "noop" as an update result, and adds more
diagnostics to the assertion failure message.
This commit adds back bundling of all deps of the sql jdbc jar. This was

When there is no persistent tasks metadata we could hit a null pointer
exception when executing a follower stats request. This is because we
inspect the persistent tasks metadata. Yet, if no tasks have been

this commit does, and we add a test for this situation.

lastAcceptedConfiguration and votingTombstones into

MetaData.toXContent and MetaData.fromXContent should take care of
CoordinationMetaData.
version stays as a top level field in ClusterState and will be
persisted as part of Manifest in a follow-up commit.
Also MetaData.isGlobalStateEquals should be extended to include
coordinationMetaData in comparison.

ClusterState to avoid massive code changes.

Move away from performing eager, fail-fast validation of mismatched

Response classes in Elasticsearch (and xpack) only need to implement ToXContent, which is needed to print their output put in the REST layer and return the response in json (or others) format. On the other hand, response classes that are added to the high-level REST client, need to do the opposite: parse xcontent and create a new object based on that.
This commit removes the parsing code from the XPackInfoResponse server variant, and the toXContent portion from the corresponding client variant. It also removes a client specific test class that looks redundant now that we have a single test class for both classes.

The DefaultAuthenticationFailureHandler has a deprecated constructor
that was present to prevent a breaking change to custom realm plugin
authors in 6.x. This commit removes the constructor and its uses.
For some time, the PutUser REST API has supported storing a pre-hashed
password for a user. The change adds validation and tests around that
feature so that it can be documented & officially supported.
It also prevents the request from containing both a "password" and a "password_hash".
This adds a `wait_for_completion` flag which allows the user to block
the Stop API until the task has actually moved to a stopped state,
instead of returning immediately. If the flag is set, a `timeout` parameter
can be specified to determine how long (at max) to block the API
call. If unspecified, the timeout is 30s.
If the timeout is exceeded before the job moves to STOPPED, a
timeout exception is thrown. Note: this is just signifying that the API
call itself timed out. The job will remain in STOPPING and evenutally
flip over to STOPPED in the background.
If the user asks the API to block, we move over the the generic
threadpool so that we don't hold up a networking thread.
This change adds a special caching reader that caches all relevant
values for a range query to rewrite correctly in a can_match phase
without actually opening the underlying directory reader. This
allows frozen indices to be filtered with can_match and in-turn
searched with wildcards in a efficient way since it allows us to
exclude shards that won't match based on their date-ranges without
opening their directory readers.

Before, moving to a failed step would only change the step info
to be that of the failed step. This means two things.
1. Async Steps would never be triggered to execute
2. If there are inherent problems with the action definition that can
be fixed with a policy update, these changes were not being reflected
by the new execution info.
Changes now
1. Async steps are executed after the move to the failed step in cluster state
2. the lifecycle execution info's phase definition is updated from the current
latest policy definition, even though the index isn't moving to a new phase.
Closes#35397.
avoid the assertions that check the log files, because that does not work on Windows.
The rest of the test is still useful and should work on Windows CI.
Currently on Windows CI this qa module fails because there is just one test and
that test si ignored if OS is Windows.
This change adds a high level freeze API that allows to mark an
index as frozen and vice versa. Indices must be closed in order to
become frozen and an open but frozen index must be closed to be
defrosted. This change also adds a index.frozen setting to
mark frozen indices and integrates the frozen engine with the
SearchOperationListener that resets and releases the directory
reader after and before search phases.

This documents how to include the search queries in the audit log.
There is a catch, that even if enabling `emit_request_body`, which should
output queries included in request bodies, search queries were not output
because, implicitly, no REST layer audit event type was included.
This folk knowledge is herein imprinted.
Many realm tests were written to use separate setting objects for
"global settings" and "realm settings".
Since #30241 there is no distinction between these settings, so these
tests can be cleaned up to use a single Settings object.

This is related to #34483. It introduces a namespaced setting for
compression that allows users to configure compression on a per remote
cluster basis. The transport.tcp.compress remains as a fallback
setting. If transport.tcp.compress is set to true, then all requests
and responses are compressed. If it is set to false, only requests to
clusters based on the cluster.remote.cluster_name.transport.compress
setting are compressed. However, after this change regardless of any
local settings, responses will be compressed if the request that is
received was compressed.
Today our OS information returned in node stats only returns a
high-level name of the OS (e.g., "Linux"). Yet, for some uses this is
too high-level and knowing at a finer level of granularity the
underlying OS can be useful. This commit extracts the pretty name on
Linux from /etc/os-release. This pretty name usually includes the Linux
vendor and the Linux vendor version number (e.g., Fedora 28).
- Introduces a transport API for bootstrapping a Zen2 cluster
- Introduces a transport API for requesting the set of nodes that a
master-eligible node has discovered and for waiting until this comprises the
expected number of nodes.
- Alters ESIntegTestCase to use these APIs when forming a cluster, rather than
injecting the initial configuration directly.
Adjust list of dynamic index settings that should be replicated

There is no longer a concept of non-global "realm settings". All realm

With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
Grammar's identifiers can be completely skipped from counting depths
as they just add another level to the tree and they are always children
of some other expression which gets counted.
Increased maximum depth from 100 to 200. After testing on production
configuration with -Xss1m, depths of at least 250 can be used, so being
conservative we put the limit lower.

The elasticsearch-croneval CLI tool uses local dates to display when
something gets triggered the next time. This is very confusing.
This commit ensures, that UTC and local timezone times will be written
out.
The output looks like this and contains localized dates for each trigger
date as well as for `now`.

This also removes an old outstanding TODO to use the jopt parsing to
cast the count to an integer instead of doing it ourselves.
In order to start shard follow tasks, the resume follow api already
needs execute N requests to the elected master node.
The pause follow API is also a master node action, which would make
how both APIs execute more consistent.
This is related to #29023. Additionally at other points we have
discussed a preference for removing the need to unnecessarily block
threads for opening new node connections. This commit lays the groudwork
for this by opening connections asynchronously at the transport level.
We still block, however, this work will make it possible to eventually
remove all blocking on new connections out of the TransportService
and Transport.
The remove-ilm-from-index API was using the DELETE http method
to signify that something is being removed. Although, metadata
about ILM for the index is being deleted, no entity/resource
is being deleted during this operation. POST is more in line with
what this API is actually doing, it is modifying the metadata for
an index. As part of this change, `remove` is also appended to the path
to be more explicit about its actions.
Error was thrown if leader index had no soft deletes enabled, but it then continued creating the follower index.
The test caught this bug, but very rarely due to timing issue.

Today if a wildcard, date-math expression or alias expands/resolves
to an index that is search-throttled we still search it. This is likely
not the desired behavior since it can unexpectedly slow down searches
significantly.
This change adds a new indices option that allows `search`, `count`
and `msearch` to ignore throttled indices by default. Users can
force expansion to throttled indices by using `ignore_throttled=true`
on the rest request to expand also to throttled indices.

This moves all Realm settings to an Affix definition.
However, because different realm types define different settings
(potentially conflicting settings) this requires that the realm type
become part of the setting key.
Thus, we now need to define realm settings as:
xpack.security.authc.realms:
file.file1:
order: 0
native.native1:
order: 1
- This is a breaking change to realm config
- This is also a breaking change to custom security realms (SecurityExtension)
This is a forward port of some of the changes made in #8445, specifically the change mentioned in https://github.com/elastic/elasticsearch/pull/34023#issuecomment-433212636.
Currently, in master, the `cluster_stats` collector collects _all_ cluster metadata and indexes it into `.monitoring-es-*`. However, per the discussion linked to above, we decided to collect _only_ the `display_name` cluster metadata setting for now. This PR makes this change.
Add NotEquals node in parser to simplify expressions so that <value1> != <value2> is
no longer translated internally to NOT(<value1> = <value2>)
Closes: #35210Fixes: #35233
This adds a new step for checking whether an index is allocated correctly based
on the rules added prior to running the shrink step. It also fixes a bug where
for shrink we are not allowed to have the shards relocating for the shrink step.
This also allows us to simplify AllocationRoutedStep and provide better
feedback in the step info for why either the allocation or the shrink checks
have failed.
Resolves#34938
If the Rollover step would fail due to the next index in sequence
already existing, just skip to the next step instead of going to the
Error step.
This prevents spurious `ResourceAlreadyExistsException`s created by
simultaneous RolloverStep executions from causing ILM to error out
unnecessarily.
This commit removes the Joda time usage from ILM and the HLRC components of ILM.
It also fixes an issue where using the `?human=true` flag could have caused the
parser not to work. These millisecond fields now follow the standard we use
elsewhere in the code, with additional fields added iff the `human` flag is
specified.
This is a breaking change for ILM, but since ILM has not yet been released, no
compatibility shim is needed.
The suite FollowerFailOverIT is failing because some documents are not
replicated to the follower. Maybe the FollowTask is not working as
expected or the background indexers eat all resources while the follower
cluster is trying to reform after a failover; then CI is not fast enough
to replicate all the indexed docs within 60 seconds (sometimes I see 80k
docs on the leader).
This commit limits the number of documents to be indexed into the leader
index by the background threads so that we can eliminate the latter
case. This change also replaces a docCount assertion with a docIds
assertion so we can have more information if these tests fail again.

Previously, testRunStateChangePolicyWithNextStep asserted that the
ClusterState before and after running the steps were equal. The test
only passed due to a race condition: The latch would be triggered by the
step execution, but the cluster state update thread would continue
running before committing the change to the cluster state. This allowed
the test to read the old cluster state and pass the equality check about
99.99% of the time.
The test now waits for the new cluster state to be committed before
checking that it is _not_ equal to the old cluster state.

Only the response classes of get auto follow pattern, the follow and stats APIs
were moved away from Streamable. The other APIs use `AcknowledgedResponse`
or `BaseTasksResponse` as response class and
moving that class away from Streamable is a bigger change.
ILM's Shrink Action was using a nodes "_name" attribute to
allocate to prepare for the shrink step. Since the name is
configurable by a user and may use the same name for
multiple nodes on one machine, _id is safer since it is guaranteed
to be unique.

Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.
Relates to #34488
Today when ESIntegTestCase starts some nodes it writes out the unicast hosts
files each time a node starts its transport service. This does mean that a
number of nodes can start and perform their first pinging round without any
unicast hosts which, if the timing is unlucky and a lot of nodes are all
started at the same time, can lead to a split brain as in #35052.
Prior to #33554 this was unlikely to happen since the MockUncasedHostsProvider
would always have yielded the existing hosts, so the timing would have to have
been implausibly unlucky. Since #33554, however, it's more likely because the
race occurs between the start of the first round of pinging and the writing of
the unicast hosts file. It is realistic that new nodes will be configured with
the existing nodes from startup, so this change reinstates that behaviour.
Closes#35052.
This commit does a few things
- moves ILM-specifc rest yaml tests into plugin/ilm/qa, and creates special
:plugin:ilm:qa:rest module to test them
- removes the with-security tests of the yaml tests since they are covered in
the rest tests now
- moves ChangePolicyforIndexIT into the qa/multi-node project since that test is
not currently running in main ilm since integTest is disabled
The java yaml test runner supports sending request headers, yet not all clients support headers. This commit makes sure that we enforce adding a skip section with feature "headers" whenever headers are used in a do section as part of a test. That decreases the chance for new tests to break client builds due to the missing skip section.

Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
The native roles store previously would issue a search if attempting to
retrieve more than a single role. This is fine when we are attempting
to retrieve all of the roles to list them in the api, but could cause
issues when attempting to find roles for a user. The search is not
prioritized over other search requests, so heavy aggregations/searches
or overloaded nodes could cause roles to be cached as missing if the
search is rejected.
When attempting to load specific roles, we know the document id for the
role that we are trying to load, which allows us to use the multi-get
api for loading these roles. This change makes use of the multi-get api
when attempting to load more than one role by name. This api is also
constrained by a threadpool but the tasks in the GET threadpool should
be quicker than searches.
See #33205
Previously, if ClusterStateActionSteps or ClusterStateWaitSteps threw an
exception executing, the exception would only be caught and logged by
the generic ClusterStateUpdateTask machinery and the index would become
stuck on that step.
Now, exceptions thrown in these steps will be caught and the index will
be moved to the Error step.
Move `x-pack/qa/smoke-test-graph-with-security` to
`x-pack/plugin/graph/qa/security` which should make it easier to run all
of the tests with a single command. It also lines up the directories
more closely with newer projects like cross cluster replication.
Moves `x-pack/qa/sql/*` into `x-pack/plugin/sql/qa` to make it simpler
to run all of the sql tests. This lines up with how newer projects like
cross cluster replication are testing themselves.
This commit filters out usage of deprecated tzs by tests. These are
tested separately and should not require checking for warnings on any
test using random timezones.

This changes the RollupSearch endpoint to proactively resolve index
patterns. If the index pattern(s) match more than one rollup index,
an exception is throw as before. But if the pattern only matches one
rollup index, execution is allowed to continue (unlike before where
it would assume all patterns were for raw data).
This also allows the search endpoint to resolve aliases that point to
a rollup index.
Also tweaks the documentation to make this clear.
Closes#34828
Conflicts during the merge:
1. >=140 chars line length fixed for a lot of project files and warnings
for those files are no longer suppressed
2. Node name is removed from AbstractComponent, it’s no longer taken

there were quite a few new classes on zen2 branch that require this
change
3. TransportResponseHandler interface changed (new method added) and
Zen2 makes a lot of subclasses in tests

Only the follow stats request couldn't be changed to use Writeable serialization,
because that requires changes in `TransportTasksAction` and `BaseTasksRequest` base classes.
Sometimes the cluster forming here will split-brain when it grows up to 5

discovery, so this asks for more logs. Relates #35052
The Move To Step API now checks to see if the target step is an
AsyncActionStep, and if so, runs it.
Previously, AsyncActionSteps would only be run when they are entered by
executing the previous step, so if an AsyncActionStep was entered via
the Move To Step API, ILM would never touch that index again.

SSLTrustRestrictionsTests.testRestrictionsAreReloaded checks that the
SSL trust configuration is automatically updated reapplied if the
underlying "trust_restrictions.yml" file is modified.
Since the default resource watcher frequency is 5seconds, it could
take 10 second to run that test (as it waits for 2 reloaded).
Previously this test set that frequency to a very low value (3ms) so
that the elapsed time for the test would be reduced. However this
caused other problems, including that the resource watcher would
frequently run while the cluster was shutting down and files were
being cleaned up.
This change resets that watch frequency back to its default (5s) and
then manually calls the "notifyNow" method on the resource watcher
whenever the restrictions file is modified, so that the SSL trust
configuration is reloaded at exactly the right time.

for the entire server and a logger are nice to have around, but not
really needed *everywhere*. The `Settings` instance especially adds a
fair bit of ceremony to testing without any value.
This removes the `nodeName` method from `AbstractComponent` so it is
more clear where we actually need the node name.
In order to remove Streamable from the codebase, Response objects need
to be read using the Writeable.Reader interface which this change
enables. This change enables the use of Writeable.Reader by adding the
`Action#getResponseReader` method. The default implementation simply
uses the existing `newResponse` method and the readFrom method. As
responses are migrated to the Writeable.Reader interface, Action
classes can be updated to throw an UnsupportedOperationException when
`newResponse` is called and override the `getResponseReader` method.

We currently have two different native processes:
autodetect & normalizer. There are plans for introducing
a new process. All these share many things in common.
This commit refactors the processes to extend an
`AbstractNativeProcess` class that encapsulates those
commonalities with the purpose of reusing the code
for new processes in the future.
Index shard stats for the follower shard are fetched, when a shard follow task is started.
This is needed in order to bootstap the shard follow task with the follower global checkpoint.
Sometimes index shard stats are not available (e.g. during a restart) and
we fail now, while it is very likely that these stats will be available some time later.
Documents the new structured logfile format for auditing
that was introduced by #31931. Most changes herein
are for 6.x . In 7.0 the deprecated format is gone and a
follow-up PR is in order.
This change ensures the `message` field is always included
in the `field_stats` for the semi-structured text log file
file structure. Previously it was not, as it will almost
certainly contain all distinct values. However, for
consistency in the UI it's useful to include it.
After discussing on the team's FixItFriday, we concluded that
static final instance variables that are mutable should be lowercased.
Historically, DeprecationLogger was uppercased more frequently than lowercased.
ILM would return a resource-not-found exception when requesting policies
while the IndexLifecycleMetaData is not initialized. The behavior here
should not be as extreme since it is not the user's fault.
This commit changes the behavior so that it succeeds and returns no policies
when no policy names are explicitely specified, otherwise keep the same behavior
of throwing an exception
Previously, for some queries the validation for ORDER BY
fields didn't kick in since a HAVING close or an ORDER BY
with scalar function would add `Filter` and `Project` plans
between the `OrderBy` and the `Aggregate`.
Now the LogicalPlan tree beneath `OrderBy` is traversed and
the ORDER BY fields are properly verified.

This is related to #30876. The AbstractSimpleTransportTestCase initiates
many tcp connections. There are normally over 1,000 connections in
TIME_WAIT at the end of the test. This is because every test opens at
least two different transports that connect to each other with 13
channel connection profiles. This commit modifies the default
connection profile used by this test to 6. One connection for each
type, except for REG which gets 2 connections.
With the introduction of _ilm/stop and _ilm/start APIs, the
use cases where one would only target a select group
of indices to start/stop has been reduced. Since there is no
strong use-case for skipping specific indices, it is best to
remove this functionality and only adding if later desired, with the
hopes of keeping things more simple.
through randomization, there is a chance that the mutateInstance
for PolicyStatsTests does not actually mutate the original object.
This PR aims to fix this

This limit is based on the size in bytes of the operations in the write buffer. If this limit is exceeded then no more read operations will be coordinated until the size in bytes of the write buffer has dropped below the configured write buffer size limit.

With this change, we apply the common test config automatically to all

For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.
The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.
Implemented null handling for both the value tested but also for

#33708 introduced a strict deprecation mode that makes a REST request
fail if there is a warning header in the response returned by
Elasticsearch (usually a deprecation message signaling that a feature
or a field has been deprecated).
This change adds the strict deprecation mode into the REST integration
tests, and makes the tests fail if a deprecated feature is used. Also
any test using a deprecated feature has been modified to pass the build.
The YAML integration tests already analyzed HTTP warnings so they do
not use this mode, keeping their "expected vs actual" behavior.
Per #31717 this commit changes the defaults to the following:
Batch size of 5120 ops.
Maximum of 12 concurrent read requests.
Maximum of 9 concurrent write requests.
This is not necessarily our final values but it's good to have these as defaults for the purposes of initial testing.
The changes introduced in cca1a2a mean that we should
not encrypt the public keys that might be generated by
the key-pair-generator when storing the file, as the code
that would consume them assumes that they are not encrypted
* Change the `TransportPauseFollowAction` to extend from `TransportMasterNodeAction`
instead of `HandledAction`, this removes a sync cluster state api call.
* Introduced `ResponseHandler` that removes duplicated code in `TransportPauseFollowAction` and
`TransportResumeFollowAction`.
* Changed `PauseFollowAction.Request` to not use `readFrom()`.
In a future major version, we will be introducing a soft limit on the
number of shards in a cluster based on the number of nodes in the
cluster. This limit will be configurable, and checked on operations
which create or open shards and issue a warning if the operation would
take the cluster over the limit.
There is an option to enable strict enforcement of the limit, which
turns the warnings into errors. In a future release, the option will be
removed and strict enforcement will be the default (and only) behavior.
Since there's no transition into the "new" phase it wasn't set until the "hot"
phase, so now we initialize it when initializing the policy context.

Both testFollowIndexAndCloseNode and testFailOverOnFollower failed

This change adds TransportService closed error to the list of retryable

As part of this change the leader index name and leader cluster name are
stored in the CCR metadata in the follow index. The resume follow api
will read that when a resume follow request is executed.
We should delete a job by directly talking to the allocated
task and telling it to shutdown. Today we shut down a job
via the persistent task framework. This is not ideal because,
while the job has been removed from the persistent task
CS, the allocated task continues to live until it gets the
shutdown message.
This means a user can delete a job, immediately delete
the rollup index, and then see new documents appear in
the just-deleted index. This happens because the indexer
in the allocated task is still running and indexes a few
more documents before getting the shutdown command.
In this PR, the transport action is changed to a TransportTasksAction,
and we invoke onCancelled() directly on the matching job.
The race condition still exists after this PR (albeit less likely),
but this was a precursor to fixing the issue and a self-contained
chunk of code. A second PR will followup to fix the race itself.

The security native stores follow a pattern where
`SecurityIndexManager#prepareIndexIfNeededThenExecute` wraps most calls
made for the security index. The reasoning behind this was to check if
the security index had been upgraded to the latest version in a
consistent manner. However, this has the potential side effect that a
read will trigger the creation of the security index or an updating of
its mappings, which can lead to issues such as failures due to put
mapping requests timing out even though we might have been able to read
from the index and get the data necessary.
This change introduces a new method, `checkIndexVersionThenExecute`,
that provides the consistent checking of the security index to make
sure it has been upgraded. That is the only check that this method
performs prior to running the passed in operation, which removes the
possible triggering of index creation and mapping updates for reads.
Additionally, areas where we do reads now check the availability of the
security index and can short circuit requests. Availability in this
context means that the index exists and all primaries are active.
This is the fixed version of #34246, which was reverted.

In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
Since #34288, we might hit deadlock if the FollowTask has more fetchers
than writers. This can happen in the following scenario:
Suppose the leader has two operations [seq#0, seq#1]; the FollowTask has
two fetchers and one writer.
1. The FollowTask issues two concurrent fetch requests: {from_seq_no: 0,
num_ops:1} and {from_seq_no: 1, num_ops:1} to read seq#0 and seq#1
respectively.
2. The second request which fetches seq#1 completes before, and then it
triggers a write request containing only seq#1.
3. The primary of a follower fails after it has replicated seq#1 to
replicas.
4. Since the old primary did not respond, the FollowTask issues another
write request containing seq#1 (resend the previous write request).
5. The new primary has seq#1 already; thus it won't replicate seq#1 to
replicas but will wait for the global checkpoint to advance at least
seq#1.
The problem is that the FollowTask has only one writer and that writer
is waiting for seq#0 which won't be delivered until the writer completed.
This PR proposes to replicate existing operations with the old primary
term (instead of the current term) on the follower. In particular, when
the following primary detects that it has processed an process already,
it will look up the term of an existing operation with the same seq_no
in the Lucene index, then rewrite that operation with the old term
before replicating it to the following replicas. This approach is
wait-free but requires soft-deletes on the follower.

Today we rely on the LocalCheckpointTracker to ensure no duplicate when
enabling optimization using max_seq_no_of_updates. The problem is that
the LocalCheckpointTracker is not fully reloaded when opening an engine
with an out-of-order index commit. Suppose the starting commit has seq#0
and seq#2, then the current LocalCheckpointTracker would return "false"
when asking if seq#2 was processed before although seq#2 in the commit.
This change scans the existing sequence numbers in the starting commit,
then marks these as completed in the LocalCheckpointTracker to ensure
the consistent state between LocalCheckpointTracker and Lucene commit.

This API is intended as a companion to the _has_privileges API.
It returns the list of privileges that are held by the current user.
This information is difficult to reason about, and consumers should
avoid making direct security decisions based solely on this data.
For example, each of the following index privileges (as well as many
more) would grant a user access to index a new document into the
"metrics-2018-08-30" index, but clients should not try and deduce
that information from this API.
- "all" on "*"
- "all" on "metrics-*"
- "write" on "metrics-2018-*"
- "write" on "metrics-2018-08-30"
Rather, if a client wished to know if a user had "index" access to
_any_ index, it would be possible to use this API to determine whether
the user has any index privileges, and on which index patterns, and
then feed those index patterns into _has_privileges in order to
determine whether the "index" privilege had been granted.
The result JSON is modelled on the Role API, with a few small changes
to reflect how privileges are modelled when multiple roles are merged
together (multiple DLS queries, multiple FLS grants, multiple global
conditions, etc).

This moves the rollup cleanup code for http tests from the high level rest

without the test having to know that it is "about rollup", and should allow
us to run the rollup docs tests.

Security caches the result of role lookups and negative lookups are
cached indefinitely. In the case of transient failures this leads to a
bad experience as the roles could truly exist. The CompositeRolesStore
needs to know if a failure occurred in one of the roles stores in order
to make the appropriate decision as it relates to caching. In order to
provide this information to the CompositeRolesStore, the return type of
methods to retrieve roles has changed to a new class,
RoleRetrievalResult. This class provides the ability to pass back an
exception to the roles store. This exception does not mean that a
request should be failed but instead serves as a signal to the roles
store that missing roles should not be cached and neither should the
combined role if there are missing roles.
As part of this, the negative lookup cache was also changed from an
unbounded cache to a cache with a configurable limit.

The ingest pipeline that is produced is very simple. It
contains a grok processor if the format is semi-structured
text, a date processor if the format contains a timestamp,

Eventually the UI should offer the option to customize the

preparation steps before ingesting data to an index.

ListenableFuture may run a listener on the same thread that called the

Today we rewrite the operations from the leader with the term of the
following primary because the follower should own its history. The
problem is that a newly promoted primary may re-assign its term to
operations which were replicated to replicas before by the previous
primary. If this happens, some operations with the same seq_no may be
assigned different terms. This is not good for the future optimistic
locking using a combination of seqno and term.
This change ensures that the primary of a follower only processes an
operation if that operation was not processed before. The skipped
operations are guaranteed to be delivered to replicas via either
primary-replica resync or peer-recovery. However, the primary must not
acknowledge until the global checkpoint is at least the highest seqno of
all skipped ops (i.e., they all have been processed on every replica).

This fixes an issue where an incorrect expected next step is used when checking
to execute `AsyncActionStep`s after a cluster state step.
It fixes this scenario:
- `ExecuteStepsUpdateTask` executes a `ClusterStateWaitStep` or
`ClusterStateActionStep` successfully
- The next step is also a `ClusterStateWaitStep`, so it loops
- The `ClusterStateWaitStep` has a next stepkey (which gets set to the
`nextStepKey` in the code)
- The `ClusterStateWaitStep` fails the condition, meaning that it will have to
wait longer
- The `nextStepKey` is now incorrect though, because we did not advance the
index's step, and it's not `null` (which is another safe value if there is no
step after the `ClusterStateWaitStep`)
This fixes the problem by resetting the nextStepKey to null if the condition is
not met, since we are not going to advance the step metadata in this
case (thereby skipping the `maybeRunAsyncAction` invocation).
This commit also tightens up and enhances much of the ILM logging. A lot of

Unfollow should be allowed / disallowed on a per index level instead of
cluster level.
Also renamed `create_follow_index` index privilege to
`manage_follow_index` privilege and include unfollow and close APIs.
This commit modifies the follow stats API response structure to more
clearly highlight meaning of the higher level fields. In particular,
previously the response had a top-level key for each index. Instead, we
nest the indices under an "indices" field which is now an array. The
values in this array are objects containing two fields: "index" which is
the name of the follower index, and "shards" which is an array where
each value in the array is the follower stats for that shard. That is,
we have gone from:
{
"bar": [
{
"shard_id": 0...
}...
]...
}
to
{
"indices": [
{
"index": "bar",
"shards": [
{
"shard_id": 0...
}...
]
}...
}
In the CCR docs we want to refer to the endpoint that returns following
stats as the follow stats API. This commit renames the internal
implementation of this endpoint to reflect this usage.
The "lookupUser" method on a realm facilitates the "run-as" and

It does this through the introduction of a new
"authentication.enabled" setting, which defaults to true.

- We don't (currently) do that everywhere (e.g. we don't cache role
mappings)
- It is sometimes necessary to clear some of those caches which can
cause significant CPU overhead and processing delays.
This commit introduces a new cache in the Automatons class to avoid
unnecesarily recomputing automatons.
There may be values in the thread context that ought to be preseved
for later use, even if one or more realms perform asynchronous
authentication.
This commit changes the AuthenticationService to wrap the potentially
asynchronous calls in a ContextPreservingActionListener that retains
the original thread context for the authentication.
This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.
This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.
Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.
Closes#32836
Drops the last logging constructor that takes `Settings` because it is
no longer needed.
Watcher goes through a lot of effort to pass `Settings` to `Logger`
constructors and dropping `Settings` from all of those calls allowed us
to remove quite a bit of log-based ceremony from watcher.
