This commit adds a new querystring parameter on the following APIs:
- Index
- Update
- Bulk
- Create Index
- Rollover
These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference
creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be
changed to `true` for 8.0+ in subsequent work.
Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting.
This setting is used so that actions that automatically create a new index (things like rollover
initiated by ILM) will inherit the preference from the original index. This setting is dynamic so
that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias
performing periodic rollover.
This also adds support for sending this parameter to the High Level Rest Client.

We don't really need `LinkedHashSet` here. We can assume that all the
entries are unique and just use a list and use the list utilities to
create the cheapest possible version of the list.
Also, this fixes a bug in `addSnapshot` which would mutate the existing
linked hash set on the current instance (fortunately this never caused a real world bug)
and brings the collection in line with the java docs on its getter that claim immutability.
* Add Snapshot Resiliency Test for Master Failover during Delete
We only have very indirect coverage of master failovers during snaphot delete
at the moment. This comment adds a direct test of this scenario and also
an assertion that makes sure we are not leaking any snapshot completion listeners
in the snapshots service in this scenario.
This gives us better coverage of scenarios like #54256 and makes the diff
to the upcoming more consistent snapshot delete implementation in #54705
smaller.
If we run into an INIT state snapshot and the current master didn't create it, it will be removed anyway.
=> no need to have that block another snapshot from starting.
This has practical relevance because on master fail-over after snapshot INIT but before start, the create snapshot request will be retried by the client (as it's a transport master node action) and needlessly fail with an unexpected exception (snapshot clearly didn't exist so it's confusing to the user).
This allowed making two disruption type tests stricter
isHidden was a `Boolean` in order to treat a special case identified
with V1 templates where if the create index request didn't specify if
the index should be hidden or not (ie. isHidden was `null`) but the
index matched a template that specified the `index.hidden` setting we
needed to remove the global templates from the templates we'll apply to
the new index (note: this is important with V1 templates as inheritance
is supported).
With V2 templates we match only one template with an index so the
equivalent check did not need to exist (we added a sanity check in
https://github.com/elastic/elasticsearch/pull/55015 where we make sure
we don't apply an invalid global template - one that specifes the
`index.hidden` setting, but this is a check we make irrespective of the
user specifying or not if the index should be hidden)
This commit makes `isHidden` when matching V2 templates a boolean
primitive, eliminating the need for the `null` state to exist. Note that
some methods which use the matching V2 templates still work with a
`Boolean` object `isHidden` attribute as they are also matching the V1
templates. These methods will pass in `false` instead of `null` when
finding the V2 templates.

Some aggregations, such as the Terms* family, will use an alternate
class to represent unmapped shard results (while the rest of the aggs
use the same object but with some form of "empty" or "nullish" values
to represent unmapped).
This was problematic with AbstractWireSerializingTestCase because it
expects the instanceReader to always match the original class. Instead,
we need to use the NamedWriteable version so that the registry
can be consulted for the proper deserialization reader.
If we start unbanning when the last child task completed and that child
task executed with a specific user, then unban requests are denied
because internal requests can't run with a user. We need to remove bans
with the current thread context.
This validates that if the winner v2 template is a global one, it doesn't specify the
index.hidden setting.

Enabled data streams and itv2 feature enabled system properties in server module's integ test task.
PR #54726 added java integration tests for data streams, so this is why these system properties
need to be enabled when running release build.
Hotfix to not run into stuck snapshots because of master circuit breaking these requests.
Given that these requests are very small and much of the memory associated with them is already allocated
when the circuit breaker kicks in, the risk of this change introducing a higher chance of master running out
of memory should be very small.
Closes#54714
We rewrite more query builders to MatchNoneQueryBuilders now, which are always
cacheable. We should make sure the tests expects this when the rewritten query
is a MatchNoneQueryBuilder.
Closes#55331
Backport from: #54726
The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.
In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.
Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

Modify the value of nowInMillis in queryShardContext to current timestamp, because the
value will be used lately when validating the filtered alias which uses now in a date_nanos
range query.
When retrieving the snapshots for a set of repos or deleting a single snapshot, it's possible for
the body of the `ActionListener`'s `onResponse` method to throw an Exception. In this case, the
`errHandler` passed in may not be executed, resulting in the `running` boolean not being reset back
to false.
This commit uses `ActionListener.wrap(...)` instead of creating a new ActionListener, which ensures
that if the `onResponse` fails in any way, the `onFailure` handler is still called.
Resolves#55217
Queries like script_score wrap a query and modify its score. If the inner query
rewrites to match_none, then the entire query can rewrite to match_none. This
lets us detect that certain shards can be skipped during the 'can match' phase.
This was a simple change that seemed like it would help in some cases. But it
will likely not have a huge impact, since in many use cases where the 'can
match' phase is helpful, the search is not sorted by score.
Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
Today the voting config exclusions API accepts node filters and resolves them
to a collection of node IDs against the current cluster membership.
This is problematic since we may want to exclude nodes that are not currently
members of the cluster. For instance:
- if attempting to remove a flaky node from the cluster you cannot reliably
exclude it from the voting configuration since it may not reliably be a
member of the cluster
- if `cluster.auto_shrink_voting_configuration: false` then naively shrinking
the cluster will remove some nodes but will leaving their node IDs in the
voting configuration. The only way to clean up the voting configuration is to
grow the cluster back to its original size (potentially replacing some of the
voting configuration) and then use the exclusions API.
This commit adds an alternative API that accepts node names and node IDs but
not node filters in general, and deprecates the current node-filters-based API.

The ResourceWatcherService enables watching of files for modifications
and deletions. During startup various consumers register the files that
should be watched by this service. There is behavior that might be
unexpected in that the service may not start polling until later in the
startup process due to the use of lifecycle states to control when the
service actually starts the jobs to monitor resources. This change
removes this unexpected behavior so that upon construction the service
has already registered its tasks to poll resources for changes. In
making this modification, the service no longer extends
AbstractLifecycleComponent and instead implements the Closeable
interface so that the polling jobs can be terminated when the service
is no longer required.

`auto_date_histogram`'s reduction behavior is fairly complex and we have
some fairly complex testing logic for it but it is super difficult to
look at that testing logic and say "ah, that is what it does in this
case". This adds some tests explicit (non-randomized) tests of the
reduction logic that *should* be easier to read.
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
Currently forbidden apis accounts for 800+ tasks in the build. These
tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance
(https://github.com/policeman-tools/forbidden-apis/pull/162), but we
need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis
usages, in preparation for upgrading to 3.0 when it is released.
Upgrade to lucene 8.5.1 release that contains a bug fix for a bug that might introduce index corruption when deleting data from an index that was previously shrunk.
We can be a little more efficient when aborting a snapshot. Since we know the new repository
data after finalizing the aborted snapshot when can pass it down to the snapshot completion listeners.
This way, we don't have to fork off to the snapshot threadpool to get the repository data when the listener completes and can directly submit the delete task with high priority straight from the cluster state thread.
Snapshot deletes should first check the cluster state for an in-progress snapshot
and try to abort it before checking the repository contents. This allows for atomically
checking and aborting a snapshot in the same cluster state update, removing all possible
races where a snapshot that is in-progress could not be found if it finishes between
checking the repository contents and the cluster state.
Also removes confusing races, where checking the cluster state off of the cluster state thread
finds an in-progress snapshot that is then not found in the cluster state update to abort it.
Finally, the logic to use the repository generation of the in-progress snapshot + 1 was error
prone because it would always fail the delete when the repository had a pending generation different from its safe generation when a snapshot started (leading to the snapshot finalizing at a
higher generation).
These issues (particularly that last point) can easily be reproduced by running `SLMSnapshotBlockingIntegTests` in a loop with current `master` (see #54766).
The snapshot resiliency test for concurrent snapshot creation and deletion was made to more
aggressively start the delete operation so that the above races would become visible.
Previously, the fact that deletes would never coincide with initializing snapshots resulted
in a number of the above races not reproducing.
This PR is the most consistent I could get snapshot deletes without changes to the state machine. The fact that aborted deletes will not put the delete operation in the cluster state before waiting for the snapshot to abort still allows for some possible (though practically very unlikely) races. These will be fixed by a state-machine change in upcoming work in #54705 (which will have a much simpler and clearer diff after this change).
Closes#54766
* Remove Redundant Cluster State during Snapshot INIT + Master Failover (#54420)
Similar to #54395 we know that a snapshot in INIT state has not
written anything to the repository yet. If we see one from a master
failover, there is no point in moving it to ABORTED before removing it
from the cluster state in a subsequent CS update.
Instead, we can simply remove its job from the CS the first time
we see it on master failover and be done with it.
* Move Snapshot Status Related Method to Appropriate Places
Lots of things living in `SnapshotsService` for no reason other than
that `SnapshotsService` provides the `RepositoriesService`.
Cleaning this up to directly use `RepositoriesService` in the relevant
transport actions and by that shortening the already very complex `SnapshotsService`.
Just like in `AbstractCoordinatorTestCase` we can't just assume the cluster
is stable once all the cluster states align since stray follower/leader check
tasks could still hit us after a disconnect, causing future test operations to fail.
=> fixed by running all tasks in the possible time span of running into these
checks before validating that cluster states align on all nodes to prevent this
like we do in the coordinator tests.
Closes#55103
Provides basic repository-level stats that will allow us to get some insight into how many
requests are actually being made by the underlying SDK. Currently only tracks GET and LIST
calls for S3 repositories. Most of the code is unfortunately boiler plate to add a new endpoint
that will help us better understand some of the low-level dynamics of searchable snapshots.
This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.
In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."
I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.
With this change, when a task is canceled, the task manager will cancel
not only its direct child tasks but all also its descendant tasks.
Closes#50990
Adds support for filters to T-Test aggregation. The filters can be used to
select populations based on some criteria and use values from the same or
different fields.
Closes#53692
The secure_settings_password was never taken into consideration in
the ReloadSecureSettings API. This commit fixes that and adds
necessary REST layer testing. Doing so, it also:
- Allows TestClusters to have a password protected keystore
so that it can be set for tests.
- Adds a parameter to the run task so that elastisearch can
be run with a password protected keystore from source.
The usage of local parameter for GetFieldMappingRequest has been removed from the underlying transport action since v2.0.
This PR deprecates the parameter from rest layer. It will be removed in next major version.
We added a fancy method to provide random realistic test data to the
reduction tests in #54910. This uses that to remove some of the more
esoteric machinations in the agg tests. This will marginally increase
the coverage of the serialiation tests and, more importantly, remove
some mysterious value generation code that only really made sense for
random reduction tests but was used all over the place. It doesn't, on
the other hand, make the tests shorter. Just *hopefully* more clear.
I only cleaned up a few tests this way. If we like this it'd probably be
worth grabbing others.
