This test failed on WindowsFS. We failed to remove the corrupted file if

Closes#66893
We started passing down the root document's _source when processing
nested hits, to avoid reloading and reparsing the root source for each hit.
Unfortunately the approach did not work when there are multiple layers of
`inner_hits`. In this case, the second-layer inner hit received its immediate
parent's source instead of the root source. This parent source is filtered to
just contain the parts corresponding to the nested document, but the source
parsing logic is designed to always operate on the top-level root source. This
caused failures when loading the second-layer inner hits.
This PR makes sure to always pass the root document's _source when processing
inner hits, even if there are multiple layers.
Previously we treated attribute filtering for _tier-prefixed attributes a pass-through, meaning
that they were essentially always treated as matching in DiscoveryNodeFilters.match, however, for
exclude settings, this meant that the node was considered to match the node if a _tier* filter was
specified.
This commit prunes these attributes from the DiscoveryNodeFilters when considering the filters for
FilterAllocationDecider so that they are only considered in DataTierAllocationDecider.
Resolves#66679
This PR fixes two bugs that can arise when _source is disabled and we fetch nested documents:

For async searches (EQL included) the client's request headers were
erroneously stored in the .tasks index. This might expose the requesting

usual approach to store only the security-internal headers, which carry

which is commonly utilized to redo authentication for scheduled tasks.

This PR fixes a regression where fvh fragments could be loaded from the wrong
document _source.
Some `FragmentsBuilder` implementations contain a `SourceLookup` to load from
_source. The lookup should be positioned to load from the current hit document.
However, since `FragmentsBuilder` are cached and shared across hits, the lookup
is never updated to load from the new documents. This means we accidentally
load _source from a different document.
The regression was introduced in #60179, which started storing `SourceLookup`
on `FragmentsBuilder`.
Fixes#65533.
This commit adjusts the behavior when calculating the diff between two
`AbstractScopedSettings` objects, so that the default values of settings
whose default values depend on the values of other settings are
correctly calculated. Previously, when calculating the diff, the default
value of a depended setting would be calculated based on the default
value of the setting(s) it depends on, rather than the current value of
those settings.
In #61906 we added the possibility for the master node to fetch
the size of a shard snapshot before allocating the shard to a
data node with enough disk space to host it. When merging
this change we agreed that any failure during size fetching
should not prevent the shard to be allocated.
Sadly it does not work as expected: the service only triggers
reroutes when fetching the size succeed but never when it
fails. It means that a shard might stay unassigned until
another cluster state update triggers a new allocation
(as in #64372). More sadly, the test I wrote was wrong as
it explicitly triggered a reroute.
This commit changes the InternalSnapshotsInfoService
so that it also triggers a reroute when fetching the snapshot
shard size failed, ensuring that the allocation can move
forward by using an UNAVAILABLE_EXPECTED_SHARD_SIZE
shard size. This unknown shard size is kept around in the
snapshot info service until no corresponding unassigned
shards need the information.

TransportService doesn't respond to the pending requests of proxy
connections when the underlying connections get disconnected because
proxy connections do not override the getCacheKey method. Some CCS
requests would never be completed because of this bug.
These strings are quite long individually and will be repeated
potentially up to the number of snapshots in the repository times.
Since these make up more than half of the size of the repository metadata
and are likely the same for all snapshots the savings from deduplicating them
can make up for more than half the size of `RepositoryData` easily in most real-world
cases.
Store stats can be `null` if e.g. the shard was already closed
when the stats where retrieved. Don't record those shards in the
sizes map to fix an NPE in this case.
When n=0 in TranslogTests.testTotalTests we never update earliestLastModifiedAge so it fails comparison with default value of total.getEarliestLastModifiedAge() which is 0.

In certain situations, such as when configured in FIPS 140 mode,
the Java security provider in use might throw a subclass of
java.lang.Error. We currently do not catch these and as a result
the JVM exits, shutting down elasticsearch.
This commit attempts to address this by catching subclasses of Error
that might be thrown for instance when a PBKDF2 implementation
is used from a Security Provider in FIPS 140 mode, with the password
input being less than 14 bytes (112 bits).
- In our PBKDF2 family of hashers, we catch the Error and
throw an ElasticsearchException while creating or verifying the
hash. We throw on verification instead of simply returning false
on purpose so that the message bubbles up and the cause becomes
obvious (otherwise it would be indistinguishable from a wrong
password).
- In KeyStoreWrapper, we catch the Error in order to wrap and re-throw
a GeneralSecurityException with a helpful message. This can happen when
using any of the keystore CLI commands, when the node starts or when we
attempt to reload secure settings.
- In the `elasticsearch-users` tool, we catch the ElasticsearchException that
the Hasher class re-throws and throw an appropriate UserException.
Tests are missing because it's not trivial to set CI in fips approved mode
right now, and thus any tests would need to be muted. There is a parallel
effort in #64024 to enable that and tests will be added in a followup.
KeyStoreAwareCommand attempted to deduce whether an error occurred
because of a wrong password by checking the cause of the
SecurityException that KeyStoreWrapper.decrypt() throws. Checking
for AEADBadTagException was wrong becase that exception could be
(and usually is) wrapped in an IOException. Furthermore, since we
are doing the check already in KeyStoreWrapper, we can just return
the message of the SecurityException to the user directly, as we do
in other places.
A bug was introduced in 7.10 that causes explicit `null` values to be indexed in the _field_names
field. This change fixes this bug for newly ingested data but `null` values ingested with 7.10 will
continue to match `exists` query so a reindex is required.
Fixes#65306
This change fixes the equals and hashCode methods of the custom FieldValuesSource
that is used internally to extract the value from a doc value field.
Using the field data instance to check equality prevented the query to be cached in
previous versions. Switching to the field name should make the query eligible for
caching again.
Watcher has a search template that stores indices options to be used as
part of a search during watch execution, but this was not updated to be
aware of hidden indices and the `hidden` expand_wildcards option. This
change makes use of the `IndicesOptions#toXContent` method in Watcher,
which already handles the new value. Additionally, the XContent parsing
is moved to the IndicesOptions class so that we will be less likely to
miss updating this in the future.

Currently a rejected execution exception can be swallowed when async
actions return during transport bulk actions. This includes scenarios
where we went async to perform ingest pipelines or index creation. This
commit resolves the issue by propagating a rejected exception.
Node roles vary by version, and new roles are suppressed for BWC. This
means we can receive a join from a node that's already in the cluster
but with a different set of roles: the node didn't change roles, but the
cluster state came via an older master. This commit ensures that we
properly process a join from such a node to ensure that the roles are
correct.
Closes#62840
This change fixes a bug introduced in #61779 that uses a compound order to
compare buckets when merging. The bug is triggered when the compound order
uses a primary sort ordered by key (asc or desc).
This commit ensures that we always extract the primary sort when comparing keys
during merging.
The PR is marked as no-issue since the bug has not been released in any official version.
This commit internalizes whether or not a role represents the ability to
contain data. In the future, this will let us remove the compatibility
role notion.
Now that we're consistently using `cat_match` to filter which shards we
run on we can get this confusing case:
1. You have a search with, say, a range and a sub-agg.
2. That search has a query that `can_match` can recognize will match no
docs. On *any* shard.
3. So we dutifully run it on a single shard so it can produce the
"empty" aggs.
4. The shard we pick happens to not have the target of the range mapped.
5. This kicks in the special range aggregator that doesn't collect any
documents.
6. Before this commit, that range aggregator *also* never produced any
sub-aggs.
So, without this change, it was quite possible for a search that
happened to match no documents to "throw away" the sub-aggs of a range
and a few other aggs.
We've had this problem for a long, long time but it is more confusing
now because `can_match` is really kicking in and causing us to see cases
where it looks like you are targeting a lot of shards but you really are
only targeting a couple. It used to be that to get the "no sub-aggs"
behavior you had to explicitly target only shards that didn't map the
target field of the `range` agg. And, like, in that case it isn't too
bad because you targeted a sort of degenerate shard. But now that
`can_match` is doing its thing you can end up with the confusing steps
above. It took me several hours to track down what what happening I know
how the individual pieces of all of this works. It took four hours to
figure out how they fit together in this case....
Anyway! This replaces all the aggregator implementations that throw out
the sub-aggregators with ones that keep them. I think this'll be less
confusing in the future.

This commit adds logging to indicate whether or not we are using the
bundled JDK. We distinguish between using a distribution that bundles
the JDK versus using a distribution that does not bundle the JDK.
In 7.x we can't just by default generate this setting as it might not be
supported by data nodes that are assigned shards for an older version in mixed version
clusters.
Closes#64152
This commit fixes an issue with the detection on macOS for whether or
not the bundled JDK is being used. The logic between macOS and non-macOS
is different because the JDK has a different directory structure on
macOS versus non-macOS. However, due to notarization issues, we changed
the top-level directory from jdk to jdk.app, yet never updated this
detection logic to account for that.
Ideally, we would have a packaging test that asserts that we have the
behavior here correct, and it maintains over time. Alas, we do not
currently have packaging tests on macOS.
With this change, we will always return the same point in time in a
search response as its input until we implement the retry mechanism
for the point in times.
The formatting of the global bottom value does not take the resolution of the provided
numeric_type into account. This change fixes this bug by providing the resolution
directly in the doc value format if the numeric_type is provided as `date_nanos`.
Closes#63719
We must not remove the snapshot from the initializing set
in the `timeout` getter. This was a plain oversight/mistake
and went unnoticed. It can lead to the removal of a valid
snapshot clone from the cluster state in rare circumstances
(e.g. when a node concurrently joins the cluster or a routing
change happens as it did in the linked test failure).
Closes#64115
If we run into a background merge between creating the snapshot and closing the index
then with compound files we could be in a situation where we get zero file reuse
on restore.
Force merging before the snapshot gives us a single segment that won't change down the line
so the restore always sees file reuse from the close index.
Closes#63476
Assuming the clone failed when the request failed is not sufficient.
There are failure modes where the request fails but the clone still works out
because the data node resent the requeest after the first clone had already been
failed and removed from the cluster state when master was restarted.
Closes#63473
We have to wait for no more operations here not for `1`. This mostly worked
because the test thread would add the listener quickly enough so that it sees the
state where either the snapshot or clone but not both have already finished
but randomly the test thread would be slow and time out on a state without snaphots in it.
testHealthOnMasterFailover could timeout on some of the health requests
in the case where an index is added, since the recovery leads to
extended test run time.
Closes#62690
We had and an error when serializing fully reduced scripted metrics.
Small typo and sever lack of tests..... Anyway, this fixed the one
character typo and adds a bunch more tests.
This commit adds a test in DiskThresholdDeciderTests that verifies
the allocation of a snapshot recovery source based shard in the
situation where the snapshot shard size was successfully provided
by the SnapshotInfoService introduced in #61906 and when the
service failed to provide the size.

In #57892 I broke *some* sub-aggregations inside of the `parent` and
`child` aggregator, specifically any sub-aggregations that do work in
the `postCollect` phase. This fixes it by delaying the post collect
phase of aggs under `parent` and `child` until `beforeBuildingBuckets`
because, well, we haven't done *any* collection until after that phase.
Currently if distance_feature query contains boost,
it incorrectly gets applied twice: in AbstractQueryBuilder::toQuery and

As a result we get incorrect scores.
This fixes this error to ensure that boost is applied only once.

Today indexing to a shard with 2147483519 documents will fail that

This fixes a gap in testing and a bug that can occur in various forms:
When we would start a snapshot or clone related to a shard that was done
snapshotting/cloning but its overall operation was not yet finalized
at the time of starting the operation, we would base the operation off of
the wrong generation. This would not cause a corrupted repo, but would
cause the operation to be `PARTIAL`.
This commit fixes the state machine to take into account the correct generation
in this case.
Closes#63498
This PR implements value fetching for the following field types:
* `text` phrase and prefix subfields
* `search_as_you_type`, plus its subfields
* `token_count`, which is implemented by fetching doc values
Supporting these types helps ensure that retrieving all fields through
`"fields": ["*"]` doesn't fail because of unsupported value fetchers.
Currently we flush the Translog buffer when a new operation causes the
buffer to breach 1MB. This introduces a scenario where an exception is
thrown AFTER the writer has accepted the operation. To avoid this, this
commit flushes the Translog in an #add call before adding a new
operation.
This fixes#63299.
This PR adds factory methods for the most common implementations:
* `SourceValueFetcher.identity` to pass through the source value untouched.
* `SourceValueFetcher.toString` to simply convert the source value to a string.
#63214 made TypeFieldType a constant field, and fixed things so that it always
emits deprecation warnings whenever it is referenced in a query or aggregation.
However, it also emits warnings when it is used to build a type filter through
the search context; this is unnecessary, as warnings are already emitted by
the REST layer when types are specified as part of the URL, and it is causing
failures in some BWC tests.
This commit adds a specialised typeFilter method to TypeFieldType to handle
this case without emitted any extra warnings. It also removes an unused duplicate
TypeFieldType class that resulted from a backport merge error.
Fixes#63366
As a result of this, we can remove a chunk of code from TypeParsers as well. Tests
for search/index mode analyzers have moved into their own file. This commit also
rationalises the serialization checks for parameters into a single SerializerCheck

itself.

We were not consistent in checking for node roles before adding listeners.
In some cases we did check the necessity of a CS listener and in others we did not.
This commit fixes a number of cases of redundant listeners that don't apply to all node roles.
In #61906 we agreed on always providing the default value
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE
when the SnasphotInfoService failed to retrieve the exact
size for a given snapshot shard. The motivation was to
allow the shard allocation to move forward in case of
failures (so that the unassigned shard does not get stuck
in an unassigned state for too long) while relying on the
fallback values for shard sizes.
Sadly a bug in the
SnapshotShardSizeInfo#getShardSize(ShardRouting, long)
makes the default value to be ignored when the snapshot
shard size retrieval previously failed, returning
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE
instead of the provided default value. With DiskThresholdDecider
also not relying on the provided default value this triggers
some assertion like in #63376 which helped us to spot the bug.
Closes ##63376
The first refreshDiskUsage() refreshes the ClusterInfo update which in turn
calls listeners like DiskThreshMonitor. This one triggers a reroute as
expected and turns an internal checkInProgress flag before submitting
a cluster state update to relocate shards (the internal flag is toggled
again once the cluster state update is processed).
In the test I suspect that the second refreshDiskUsage() may complete
before DiskThreshMonitor's internal flag is set back to its initial state,
resulting in the second ClusterInfo update to be ignored and message
like "[node_t0] skipping monitor as a check is already in progress" to
be logged. Adding another wait for languid events to be processed
before executing the second refreshDiskUsage() should help here.
Closes#62326
Currently we add translog operation bytes to an array list and flush
them on the next write. Unfortunately, this does not currently play well
with our byte pooling which means each operation is backed, at minimum,
by a 16KB array. This commit improves memory efficiency for small
operations by serializing the operations to an output stream.
Currently a TranslogWriter add operation is synchronized. This operation
adds the bytes to the file output stream buffer and issues a write
system call if the buffer is filled. This happens every 8KB which means
that we routinely block other add calls on system writes.
This commit modifies the add operation to simply place the operation in
an array list. The array list if flushed when the sync call occurs or
when 1MB is buffered.
Plugins are loaded in isolated child class loaders of the root class loader. However, some libraries depend on the context class loader being set. This commit sets the context class loader for the duration of calling each plugins constructor.

When constructing a value fetcher, the 'parsesArrayValue' flag must match
`FieldMapper#parsesArrayValue`. However there is nothing in code or tests to
help enforce this.
This PR reworks the value fetcher constructors so that `parsesArrayValue` is
'false' by default. Just as for `FieldMapper#parsesArrayValue`, field types must
explicitly set it to true and ensure the behavior is covered by tests.
Follow-up to #62974.
This PR adds deprecation warnings when accessing System Indices via the REST layer. At this time, these warnings are only enabled for Snapshot builds by default, to allow projects external to Elasticsearch additional time to adjust their access patterns.
Deprecation warnings will be triggered by all REST requests which access registered System Indices, except for purpose-specific APIs which access System Indices as an implementation detail a few specific APIs which will continue to allow access to system indices by default:
- `GET _cluster/health`
- `GET {index}/_recovery`
- `GET _cluster/allocation/explain`
- `GET _cluster/state`
- `POST _cluster/reroute`
- `GET {index}/_stats`
- `GET {index}/_segments`
- `GET {index}/_shard_stores`
- `GET _cat/[indices,aliases,health,recovery,shards,segments]`
Deprecation warnings for accessing system indices take the form:
```
this request accesses system indices: [.some_system_index], but in a future major version, direct access to system indices will be prevented by default
```
Determines the shard size of shards before allocating shards that are
recovering from snapshots. It ensures during shard allocation that the
target node that is selected as recovery target will have enough free
disk space for the recovery event. This applies to regular restores,
CCR bootstrap from remote, as well as mounting searchable snapshots.
The InternalSnapshotInfoService is responsible for fetching snapshot
shard sizes from repositories. It provides a getShardSize() method
to other components of the system that can be used to retrieve the
latest known shard size. If the latest snapshot shard size retrieval
failed, the getShardSize() returns
ShardRouting.UNAVAILABLE_EXPECTED_SHARD_SIZE. While
we'd like a better way to handle such failures, returning this value
allows to keep the existing behavior for now.
Note that this PR does not address an issues (we already have today)
where a replica is being allocated without knowing how much disk
space is being used by the primary.

Even if we increase the limit it might not take effect straight away if a thread is
blocked on a long wait in `org.elasticsearch.index.snapshots.blobstore.RateLimitingInputStream#maybePause`.
Let's increase the limit a little and see if that deals with the remaining failures for good and stop burning
cycles busy asserting a future completion.

MapperService carries a lot of weight and is only used to determine if loading of field data for the id field is enabled, which can be done in a different way.
Just a few spots where we can dry up these tests using the snapshot test infrastructure
in core that I found while studying the existing searchable snapshot tests.
In #62509 we already plugged faster sequential access for stored fields in the fetch phase.
This PR now adds using the potentially better field reader also in SourceLookup.
Rally exeriments are showing that this speeds up e.g. when runtime fields that are using
"_source" are added e.g. via "docvalue_fields" or are used in queries or aggs.
Closes#62621
In 6x and 7x, indexes can have only one type, which means that we can rework
all queries against the type field to use a ConstantFieldType. This has already
been done in master with the removal of the TypeFieldMapper, but we still need
that class in 7x to deal with nested documents. This commit leaves
TypeFieldMapper in place, but refactors TypeFieldType to extend
ConstantFieldType and consolidates deprecation warnings within that class.
It also incidentally removes the requirement to pass a MapperService to
IndexFieldData.Builder#build, which should allow #63197 to be backported.
There is no need to let snapshots that haven't yet written anything to the repo
finalize with `FAILED`. When we still had the `INIT` state we would also just remove
these snapshots from the state without any further action.
This is not just a theoretical optimization. Currently, the situation of having a lot of
queued up snapshots is fairly complicated to resolve when all the queued shards move to aborted
since it is now necessary to execute tasks on the `SNAPSHOT` pool (that might be very busy) to
remove the snapshot from the CS (including a number of redundant CS updates and repo writes
for finalizing these snapshots before deleting them right away after).
If the connection between clusters is disconnected or the leader cluster
is offline, then CCR shard-follow tasks can stop with "no seed node
left". CCR should retry on this error.
The copy constructors previously used were hard to read and the exact state changes
were not obvious at all.
Refactored those into a number of named constructors instead, added additional assertions
and moved the snapshot abort logic into `SnapshotsInProgress`.
In #63242 we changed how we build `nextRoundingValue` to, well, be
correct. But the old `org.elasticsearch.common.rounding.Rounding`
implementation didn't get the fix. Which is fine, because it doesn't
that method on that implementation doesn't receive any use outside of
tests. In fact, it is entirely removed in master. Anyway, now that the
two implementation produce different values we really can't go around
asserting that they produce the same values now can we? Well, we were!
This skips that assertion if we know `nextRoundingValue` is implemented
differently.
Closes#63256
* Setting `script.painless.regex.enabled` has a new option,
`use-factor`, the default. This defaults to using regular
expressions but limiting the complexity of the regular
expressions.
In addition to `use-factor`, the setting can be `true`, as
before, which enables regular expressions without limiting them.
`false` totally disables regular expressions, which was the
old default.
* New setting `script.painless.regex.limit-factor`. This limits
regular expression complexity by limiting the number characters
a regular expression can consider based on input length.
The default is `6`, so a regular expression can consider
`6` * input length number of characters. With input
`foobarbaz` (length `9`), for example, the regular expression
can consider `54` (`6 * 9`) characters.
This reduces the impact of exponential backtracking in Java's
regular expression engine.
* add `@inject_constant` annotation to whitelist.
This annotation signals that a compiler settings will
be injected at the beginning of a whitelisted method.
The format is `argnum=settingname`:
`1=foo_setting 2=bar_setting`.
Argument numbers must start at one and must be sequential.
* Augment
`Pattern.split(CharSequence)`
`Pattern.split(CharSequence, int)`,
`Pattern.splitAsStream(CharSequence)`
`Pattern.matcher(CharSequence)`
to take the value of `script.painless.regex.limit-factor` as a
an injected parameter, limiting as explained above when this
setting is in use.

We only ever use this with `XContentParser` no need to make it inline
worse by forcing the lambda and hence dynamic callsite here.
=> Extraced the exception formatting code path that is likely very cold
to a separate method and removed the lambda usage in hot loops by simplifying
the signature here.
Small refactoring to shorten the diff with the clone logic in #61839:
* Since clones will create a different kind of shard state update that
isn't the same request sent by the snapshot shards service (and cannot be
the same request because we have no `ShardId`) base the shard state updates
on a different class that can be extended to be general enough to accomodate
shard clones as well.
* Make the update executor a singleton (can't make it an inline lambda as that
would break CS update batching because the executor is used as a map key but
this change still makes it crystal clear that there's no internal state to the
executor)
* Make shard state update responses a singleton (can't use TransportResponse.Empty because
we need an action response but still it makes it clear that there's no actual
response with content here)
* Just some obvious drying up of these super complex tests.
* Mainly just shortening the diff of #61839 here by moving test utilities
to the abstract test case.
Also, making use of the now available functionality to simplify existing tests
and improve logging in them.
"interval" style roundings were implementing `nextRoundingValue` in a
fairly inconsistent way - it'd produce a value, but sometimes that
value would be the same as the previous rounding value. This makes it
consistently the next value that `rounding` would make.
As long as `bestEffortConsistency` is `true`, the value of `latestKnownRepoGen`
can be updated as a result of reads. We can only assert that `latestKnownRepoGen`
and cluster state move in lock-step if `bestEffortConsistency` was `false` before
updating the metadata generation as well as after.
Closes#62877
There is a small race when processing the cluster state that is used to
establish a newly elected leader as master of the cluster: it can pick the term
in its master state update task from a different (newer) election. This trips
an assertion in `Coordinator.publish(...)` where we claim that the term on the
state allows to uniquely define the pre-state but this isn't so. There are no
bad consequences of this race since such a publication fails later on anyway.
This PR fixes things so that the assertion holds true by improving the handling
of terms during cluster state processing by associating each master state
update task that is used to establish a newly elected leader with the correct
corresponding term from its election. It also explicitly handles the case where
the pre-state that is used as base state has already superseded the current
state. As a nice side-effect, join batching now only happens based on the same
term.
Closes#61437
The iteration over `timeoutClusterStateListeners` starts when the CS applier
thread is still running. This can lead to entries being added to it that never
get their listener resolved on shutdown and thus leak that listener as observed
in a stuck test in #62863.
Since `listener.onClose()` is idempotent we can just call it if we run into a stopped service
on the CS thread to avoid the race with certainty (because the iteration in `doStop` starts after
the stopped state has been set).
Closes#62863
For runtime fields, we will want to do all search-time interaction with
a field definition via a MappedFieldType, rather than a FieldMapper, to
avoid interfering with the logic of document parsing. Currently, fetching
values for runtime scripts and for building top hits responses need to
call a method on FieldMapper. This commit moves this method to
MappedFieldType, incidentally simplifying the current call sites and freeing
us up to implement runtime fields as pure MappedFieldType objects.
In #22721, the decision to throttle indexing was inadvertently flipped,
so that we until this commit throttle indexing during recovery but
never throttle user initiated indexing requests. This commit

throttle recovery requests.

* Add System Indices check to AutoCreateIndex
By default, Elasticsearch auto-creates indices when a document is
submitted to a non-existent index. There is a setting that allows users
to disable this behavior. However, this setting should not apply to
system indices, so that Elasticsearch modules and plugins are able to
use auto-create behavior whether or not it is exposed to users.
This commit constructs the AutoCreateIndex object with a reference to
the SystemIndices object so that we bypass the check for the user-facing
autocreate setting when it's a system index that is being autocreated.
We also modify the logic in TransportBulkAction to make sure that if a
system index is included in a bulk request, we don't skip the
autocreation step.
It extracts the query capabilities from AbstractGeometryFieldType into two new interfaces, GeoshapeQueryable and ShapeQueryable. Those interfaces are implemented by the final mappers.
Today InternalClusterInfoService ignores hidden indices when
retrieving shard stats of the cluster. This can lead to suboptimal
shard allocation decisions as the size of shards are taken into
account when allocating new shards or rebalancing existing shards.
This converts RankFeatureFieldMapper, RankFeaturesFieldMapper,
SearchAsYouTypeFieldMapper and TokenCountFieldMapper to
parametrized forms. It also adds a TextParams utility class to core
containing functions that help declare text parameters - mainly shared
between SearchAsYouTypeFieldMapper and KeywordFieldMapper at
the moment, but it will come in handy when we convert TextFieldMapper
and friends.

Currently, `finishHim` can either execute on the specified executor
(in the less likely case that the local node request is the last to arrive)
or on a transport thread.
In case of e.g. `org.elasticsearch.action.admin.cluster.stats.TransportClusterStatsAction`
this leads to an expensive execution that deserializes all mapping metadata in the cluster
running on the transport thread and destabilizing the cluster. In case of this transport
action it was specifically moved to the `MANAGEMENT` thread to avoid the high cost of processing
the stats requests on the nodes during fan-out but that did not cover the final execution
on the node that received the initial request. This PR adds to ability to optionally specify the executor for the final step of the
nodes request execution and uses that to work around the issue for the slow `TransportClusterStatsAction`.
Note: the specific problem that motivated this PR is essentially the same as https://github.com/elastic/elasticsearch/pull/57937 where we moved the execution off the transport and on the management thread as a fix as well.
Passing FieldMappers to point parsing functions makes trying to build source-only
fields from MappedFieldTypes more complicated. This small refactoring changes
things so that the relevant parsing and factory functions from
AbstractGeometryFieldMapper are instead passed as lambdas to the PointParser
constructor.

This commit adds a mechanism to MapperTestCase that allows implementing
test classes to check that their parameters can be updated, or throw conflict
errors as advertised. Child classes override the registerParameters method
and tell the passed-in UpdateChecker class about their parameters. Simple
conflicts can be checked, using the existing minimal mappings as a base to
compare against, or alternatively a particular initial mapping can be provided
to check edge cases (eg, norms can be updated from true to false, but not
vice versa). Updates are registered with a predicate that checks that the update
has in fact been applied to the resulting FieldMapper.
Fixes#61631
This commit allows coordinating node to account the memory used to perform partial and final reduce of
aggregations in the request circuit breaker. The search coordinator adds the memory that it used to save
and reduce the results of shard aggregations in the request circuit breaker. Before any partial or final
reduce, the memory needed to reduce the aggregations is estimated and a CircuitBreakingException} is thrown
if exceeds the maximum memory allowed in this breaker.
This size is estimated as roughly 1.5 times the size of the serialized aggregations that need to be reduced.
This estimation can be completely off for some aggregations but it is corrected with the real size after
the reduce completes.
If the reduce is successful, we update the circuit breaker to remove the size of the source aggregations
and replace the estimation with the serialized size of the newly reduced result.
As a follow up we could trigger partial reduces based on the memory accounted in the circuit breaker instead
of relying on a static number of shard responses. A simpler follow up that could be done in the mean time is
to [reduce the default batch reduce size](https://github.com/elastic/elasticsearch/issues/51857) of blocking
search request to a more sane number.

Today if a data stream is auto created, but an index with same name as the
first backing index already exists then internally that error is ignored,
which then result that later in the execution of a bulk request, the
bulk item fails due to that the data stream hasn't been auto created.
This situation can only occur if an index with same is created that
will be the backing index of a data stream prior to the creation
of the data stream.

A few of us were talking about ways to speed up the `date_histogram`
using the index for the timestamp rather than the doc values. To do that
we'd have to pre-compute all of the "round down" points in the index. It
turns out that *just* precomputing those values speeds up rounding
fairly significantly:
```

```
That's a 46% speed up when there isn't a time zone and a 58% speed up
when there is.
This doesn't work for every time zone, specifically those that have two
midnights in a single day due to daylight savings time will produce wonky
results. So they don't get the optimization.
Second, this requires a few expensive computation up front to make the
transition array. And if the transition array is too large then we give
up and use the original mechanism, throwing away all of the work we did
to build the array. This seems appropriate for most usages of `round`,
but this change uses it for *all* usages of `round`. That seems ok for
now, but it might be worth investigating in a follow up.
I ran a macrobenchmark as well which showed an 11% preformance
improvement. *BUT* the benchmark wasn't tuned for my desktop so it
overwhelmed it and might have produced "funny" results. I think it is
pretty clear that this is an improvement, but know the measurement is
weird:

The name `FieldFetcher` fits better with the 'fetch' terminology we use
elsewhere, for example `FetchFieldsPhase` and `ValueFetcher`.
This PR also moves the construction of the fetcher off the context and onto
`FetchFieldsPhase`, which feels like a more natural place for it, and fixes a
TODO in javadocs.
This test checks to see if the index has been created before version 6.4, in which
case index prefixes are unavailable and so it expects to see a span multi-term
wrapper. However, the production code doesn't bother with checking for versions,
because if the field in question is configured with index_prefixes then it knows that
it must have been created post 6.4 (you can't merge in a new index_prefixes
configuration).
This commit alters the test to remove the random version checks, as we know we
will always have a prefix field available in this scenario.
Fixes#58199
Backport #62766 to 7.x branch.
The bulk api cache the resolved concrete indices when resolving the user provided
index name into the actual index name. The validation that prevents write ops other
than create from being executed in a data stream was only performed if the result
wasn't cached. In case of cached resolvings, the validation never occurs.
The validation would be skipped for all bulk items for a data stream after a create
operation for that same data stream. This commit ensures that the validation is always
performed for all bulk items (whether the concrete index resolution has been cached or
not cached).
Closes#62762
This change adds support for the recently introduced case insensitivity flag for
wildcard and prefix queries. Since version field values are encoded differently we
need to adapt our own AutomatonQuery variation to add both cases if case insensitivity
is turned on.
Most of our field types have the same implementation for their `existsQuery` method which relies on doc_values if present, otherwise it queries norms if available or uses a term query against the _field_names meta field. This standard implementation is repeated in many different mappers.
There are field types that only query doc_values, because they always have them, and field types that always query _field_names, because they never have norms nor doc_values. We could apply the same standard logic to all of these field types as `MappedFieldType` has the knowledge about what data structures are available.
This commit introduces a standard implementation that does the right thing depending on the data structure that is available. With that only field types that require a different behaviour need to override the existsQuery method.
At the same time, this no longer forces subclasses to override `existsQuery`, which could be forgotten when needed. To address this we introduced a new test method in `MapperTestCase` that verifies the `existsQuery` being generated and its consistency with the available data structures.
This commit adds a dedicated threadpool for system index write
operations. The dedicated resources for system index writes serves as
a means to ensure that user activity does not block important system
operations from occurring such as the management of users and roles.

* [ML] changing to not use global bulk indexing parameters in conjunction with add(object) calls (#62694)
* [ML] changing to not use global bulk indexing parameters in conjunction with add(object) calls
global parameters, outside of the global index, are ignored for internal callers in certain cases.
If the interal caller is adding requests via the following methods:
```
- BulkRequest#add(IndexRequest)
- BulkRequest#add(UpdateRequest)
- BulkRequest#add(DocWriteRequest)
- BulkRequest#add(DocWriteRequest[])
```
It is better to specifically set the desired parameters on the requests before they are added
to the bulk request object.

Closes#61660. When ordering shard for recovery, ensure system index shards are
ordered first so that their recovery will be started first.
Note that I rewrote PriorityComparatorTests to use IndexMetadata instead of its
local IndexMeta POJO.
In #52680 we introduced a mechanism that will allow nodes to remove
themselves from the cluster if they locally determine themselves to be
unhealthy. The only check today is that their data paths are all
empirically writeable. This commit extends this check to consider a
failure of `NodeEnvironment#assertEnvIsLocked()` to be an indication of
unhealthiness.
Closes#58373
`RepositoriesService#doClose` was never called which lead to
mock repositories not unblocking until the `ThreadPool` interrupts
all threads. Thus stopping a node that is blocked on a mock repository operation wastes `10s`
in each test that does it (which is quite a few as it turns out).
There's possible retries here that work out if both the snapshot and the delete
operation are retried when master shuts down and hits the unlikely case of the retried delete
executing before the retried snapshot, making both operations pass.
Closes#62686
The dense vector field is not aggregatable although it produces fielddata through its BinaryDocValuesField. It should pass up hasDocValues set to true to its parent class in its constructor, and return isAggregatable false. Same for the sparse vector field (only in 7.x).
This may not have consequences today, but it will be important once we try to share the same exists query implementation throughout all of the mappers with #57607.
CCS with remote indices only does not require any privileges on the local cluster.
This PR ensures that search with scroll follow the permission model.
This commit ensures that the final order of the terms aggregations
is registered correctly after the final reduce.
This bug was introduced in #62028 which is not released yet so this PR is marked
as a non-issue.
This issue was discovered when running a terms aggregation under an auto-date
histogram. In such a case, the auto-date histogram may run multiple final reduce
to merge buckets together. This change makes sure that running multiple final reduces
doesn't create duplicates but it doesn't fix the fact that the final reduce may prune
the list of terms prematurely. This other bug is tracked separately in #62731.
This assertion does not always hold because there can be a race between
`putReaderContext` and `afterIndexRemoved` when an index is deleted.
Closes#62624
This is a follow up of #62480 where we are oversizing one array when initialising. In addition it prevents a possible CircuitBreaker leak during initialisation.
Make serializing `RepositoryData` a little faster and split up/document the code for it a little
as well given how massive this method has gotten at this point.
As part of the conversion, adds the ability to customize merge validation - in this case, we
allow an update to the constant value if it is currently set to null, but refuse further
updates once it has been set once.
This commit also converts ParametrizedMapperTests to use MapperServiceTestCase.
If HyperLogLogPlusPlus failed during construction, it would
not release already allocated resources, causing the request
circuit breaker to not be adjusted down.
Closes#62439
This PR adds a new 'version' field type that allows indexing string values
representing software versions similar to the ones defined in the Semantic
Versioning definition (semver.org). The field behaves very similar to a
'keyword' field but allows efficient sorting and range queries that take into
accound the special ordering needed for version strings. For example, the main
version parts are sorted numerically (ie 2.0.0 < 11.0.0) whereas this wouldn't
be possible with 'keyword' fields today.
Valid version values are similar to the Semantic Versioning definition, with the
notable exception that in addition to the "main" version consiting of
major.minor.patch, we allow less or more than three numeric identifiers, i.e.
"1.2" or "1.4.6.123.12" are treated as valid too.

The `standard` tokenfilter was removed by #33310, and should have been
unuseable in any indexes created since 7.0. However, a cacheing bug fixed
by #51092 meant that it was still possible in certain circumstances to create
indexes referencing the standard filter in versions up to 7.5.2. Our checks
in AnalysisModule still refer to 7.0.0, however, meaning that a cluster that
contains one of these rogue indexes cannot be upgraded.
This commit adjusts the AnalysisModule checks so that we only refuse to
build a mapping referring to standard filter if the index created version is
7.6 or later.
Fixes#62644
In the context of of a recurring test failure tracked by #32827, we added trace logging and an extra cache key renderer argument to IndicesRequestCache#getOrCompute (see #39475 and #34180).
We addressed the issue with #54071, but the extra argument was left behind, with a NORELEASE comment saying it should be removed.
With this commit, we remove the extra cache key rendered argument and the corresponding log lines which are not so useful without it.
Closes#55837
This commit adds the `index.routing.allocation.prefer._tier` setting to the
`DataTierAllocationDecider`. This special-purpose allocation setting lets a user specify a
preference-based list of tiers for an index to be assigned to. For example, if the setting were set
to:
```
"index.routing.allocation.prefer._tier": "data_hot,data_warm,data_content"
```
If the cluster contains any nodes with the `data_hot` role, the decider will only allow them to be
allocated on the `data_hot` node(s). If there are no `data_hot` nodes, but there are `data_warm` and
`data_content` nodes, then the index will be allowed to be allocated on `data_warm` nodes.
This allows us to specify an index's preference for tier(s) without causing the index to be
unassigned if no nodes of a preferred tier are available.
Subsequent work will change the ILM migration to make additional use of this setting.

We removed index-time boosting back in 5x, and we no longer document the 'boost'
parameter on any of our mapping types. However, it is still possible to define an
index-time boost on a field mapper for a surprisingly large number of field types, and
they even have an effect (sometimes, on some queries).
As a first step in finally removing all traces of index time boosting, this comment emits
a deprecation warning whenever a boost parameter is found on a mapping definition.
