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.
Change `nullable()` logic of AND and OR to false since in the Optimizer

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).
Adjust list of dynamic index settings that should be replicated
and added a test that verifies whether builtin dynamic index settings
are classified as replicated or non replicated (whitelisted).

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

This commit ensures, that UTC and local timezone times will be written

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

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.
Relates #33337
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.
Include `null` literals when generating the painless script for `IN` expressions.

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
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
nodes. This could be a timing issue or could be something going wrong in
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.

Drops the `deprecationLogger` from `AbstractComponent`, moving it to
places where we need it. This saves us from building a bunch of
`DeprecationLogger`s that we don't need.
Relates to #34488
`AbstractComponent` is trouble because its name implies that
*everything* should extend from it. It *is* useful, but maybe too
broadly useful. The things it offers access too, the `Settings` instance
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.
