This adds validation to make sure alias operations (add, remove, remove index)
don't target data streams or the backing indices.

Fixes a bug in TextFieldMapper serialization when index is false, and adds a
base-class test to ensure that all field mappers are tested against all variations
with defaults both included and excluded.
Fixes#58188
This is currently used to set the indexVersionCreated parameter on FieldMapper.
However, this parameter is only actually used by two implementations, and clutters
the API considerably. We should just remove it, and use it directly in the
implementations that require it.
When a numeric value in e.g. a `term` query doesn't fit into a long, it
curerently gets parsed to a BigInteger object, that the various term query
builders store untouched. This leads to serialization errors when these queries
are sent across the wire. Instead we can convert to a string representation
early on, since that is what we store e.g. when indexing big integers into
`keyword` fields anyway.
Closes#57917
This change allows to use an `index_filter` in the
field capabilities API. Indices are filtered from
the response if the provided query rewrites to `match_none`
on every shard:
````
GET metrics-*
{
"index_filter": {
"bool": {
"must": [
"range": {
"@timestamp": {
"gt": "2019"
}
}
}
}
}
````
The filtering is done on a best-effort basis, it uses the can match phase
to rewrite queries to `match_none` instead of fully executing the request.
The first shard that can match the filter is used to create the field
capabilities response for the entire index.
Closes#56195
This allows doing true CAS operations on aliases, making sure that an alias is actually properly
moved from a given source index onto a given target index. This is useful to ensure that an
alias is actually moved from a given index to another one, and not just added to another index.
Currently a failed replication action will fail an entire replica. This
includes when replication fails due to potentially short lived transient
issues such as network distruptions or circuit breaking errors.
This commit implements retries using the retryable action.
Forgot the brackets here in #58214 so in the rare case where the
first update seen by the listener doesn't match it will still remove
itself and never be invoked again -> timeout.
This builds an `auto_date_histogram` aggregator that natively aggregates
from many buckets and uses it when the `auto_date_histogram` used to use
`asMultiBucketAggregator` which should save a significant amount of
memory in those cases. In particular, this happens when
`auto_date_histogram` is a sub-aggregator of a multi-bucketing aggregator
like `terms` or `histogram` or `filters`. For the most part we preserve
the original implementation when `auto_date_histogram` only collects from
a single bucket.
It isn't possible to "just port the aggregator" without taking a pretty
significant performance hit because we used to rewrite all of the
buckets every time we switched to a coarser and coarser rounding
configuration. Without some major surgery to how to delay sub-aggs
we'd end up rewriting the delay list zillions of time if there are many
buckets.
The multi-bucket version of the aggregator has a "budget" of "wasted"
buckets and only rewrites all of the buckets when we exceed that budget.
Now that we don't rebucket every time we increase the rounding we can no
longer get an accurate count of the number of buckets! So instead the
aggregator uses an estimate of the number of buckets to trigger switching
to a coarser rounding. This estimate is likely to be *terrible* when
buckets are far apart compared to the rounding. So it also uses the
difference between the first and last bucket to trigger switching to a
coarser rounding. Which covers for the shortcomings of the bucket
estimation technique pretty well. It also causes the aggregator to emit
fewer buckets in cases where they'd be reduced together on the
coordinating node. This is wonderful! But probably fairly rare.
All of that does buy us some speed improvements when the aggregator is
a child of multi-bucket aggregator:
Without metrics or time zone: 25% faster
With metrics: 15% faster
With time zone: 22% faster

This commit bumps our JNA dependency from 4.5.1 to 5.5.0, so that we are
now on the latest maintained line, and pick up a large collection of bug
fixes that have accumulated.
This was a really subtle bug that we introduced a long time ago.
If a shard snapshot is in aborted state but hasn't started snapshotting on a node
we can only send the failed notification for it if the shard was actually supposed
to execute on the local node.
Without this fix, if shard snapshots were spread out across at least two data nodes
(so that each data node does not have all the primaries) the abort would actually
never wait on the data nodes. This isn't a big deal with uuid shard generations
but could lead to potential corruption on S3 when using numeric shard generations
(albeit very unlikely now that we have the 3 minute wait there).
Another negative side-effect of this bug was that master would receive a lot more
shard status update messages for aborted shards since each data node not assigned
a primary would send one message for that primary.
The dangling indices action is not a proper master node action so it does not
retry when executed while the cluster hasn't fully formed yet.
Since we use node restarts when setting up the dangling indices state we need
to manually ensure a fully formed cluster before moving on with the tests to avoid
failures.
Backport of #50920. Part of #48366. Implement an API for listing,
importing and deleting dangling indices.

MappedFieldType is a combination of two concerns:
* an extension of lucene's FieldType, defining how a field should be indexed
* a set of query factory methods, defining how a field should be searched
We want to break these two concerns apart. This commit is a first step to doing this, breaking
the inheritance relationship between MappedFieldType and FieldType. MappedFieldType
instead has a series of boolean flags defining whether or not the field is searchable or
aggregatable, and FieldMapper has a separate FieldType passed to its constructor defining
how indexing should be done.

* Fix compilation for backport
Co-authored-by: Gaurav Chandani <chngau@amazon.com>
After an index has been deleted it may take some time to cancel all the
maintenance tasks such as RetentionLeaseSync, it's possible that the
task is already executing before the cancellation. This commit just
avoids logging a warning message for those scenarios.
Closes#57864
Backport of (#58098)
This commit adds an optional field, `description`, to all ingest processors
so that users can explain the purpose of the specific processor instance.
Closes#56000.
Instead of serializing compilation using a plain lock / mutex combined with a double check, rely on the computeIfAbsent logic to prevent duplicated compilation of scripts. Made checkCompilationLimit to be thread-safe and lock free.
Backport: 865acad

This need some reorg of BinaryDV field data classes to allow specialisation of scripted doc values.
Moved common logic to a new abstract base class and added a new subclass to return string-based representations to scripts.
Closes#58044
* Remove usage of deprecated testCompile configuration
* Replace testCompile usage by testImplementation
* Make testImplementation non transitive by default (as we did for testCompile)
* Update CONTRIBUTING about using testImplementation for test dependencies
* Fail on testCompile configuration usage
We keep a static list of meta-fields: META_FIELDS_BEFORE_7_8
as it was before.
This is done to ensure the backwards compatability with pre 7.8 nodes.
Closes#57831
If `ExtraFS` decides to put `extra0/0` into the indices folder
then the previous logic in this test would have interpreted the `0`
as shard `0` of index `extra0` and fail to list its contents (since it's a file
and not an actual shard directory).
=> simplified the logic to use actually referenced `IndexId` for iterating over indices
instead.
Scheduling on the threadpool will throw if the scheduler is already
shut down. Handled by treating the rejection like any other non-retryable
exception.
Closes#58021
This moves the code to look up significance heuristics information like
background frequency and superset size out of
`SignificantTermsAggregatorFactory` and into its own home so that it is
easier to pass around. This will:
1. Make us feel better about ourselves for not passing around the
factory, which is really *supposed* to be a throw away thing.
2. Abstract the significance lookup logic so we can reuse it for the
`significant_text` aggregation.
3. Make if very simple to cache the background frequencies which should
speed up when the agg is a sub-agg. We had done this for numerics
but not string-shaped significant terms.
When a search phase fails, we release the context of all successful shards.
Successful shards that rewrite the request to match none will not create any context
since #. This change ensures that we don't try to release a `null` context on these
successful shards.
