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.

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.

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.
Closes#57945
Ensures that InternalClusterInfoService's internally cached stats are refreshed whenever the
shard size or disk usage function (to mock out disk usage) are overridden.
Closes#57888
Today `InternalEngine#releaseIndexCommit` fails with an
`AlreadyClosedException` if the engine is closed before the index commit is
released. This can happen if, for example, a node leaves and rejoins the
cluster and acquires an index commit for replica shard allocation concurrently
with shutting the shard down.
There's no need to fail the operation like this: if the engine is shut down
then we will clean up the unreferenced files when it's restarted (or if it's
allocated elsewhere) so we can suppress an `AlreadyClosedException` in this
case. This commit does so.
Fixes#57797
Per 49554 I added standard deviation sampling and variance sampling to the extended stats interface.

When reducing `auto_date_histogram` we were using `Rounding#round`
which is quite a bit more expensive than
```
Rounding.Prepared prepared = rounding.prepare(min, max);
long result = prepared.round(date);
```
when rounding to a non-fixed time zone like `America/New_York`. This
stops using the former and starts using the latter.

Use the the hack used in `CorruptedBlobStoreRepositoryIT` in more snapshot
failure tests to verify that BwC repository metadata is handled properly
in these so far not-test-covered scenarios.
Also, some minor related dry-up of snapshot tests.
Relates #57798
Adds assertions to Netty to make sure that its threads are not polluted by thread contexts (and
also that thread contexts are not leaked). Moves the ClusterApplierService to use the system
context (same as we do for MasterService), which allows to remove a hack from
TemplateUgradeService and makes it clearer that applying CS updates is fully executing under
system context.
If a node is disconnected we retry. It does not make sense
to retry the recovery if the node is removed from the cluster though.
=> added a CS listener that cancels the recovery for removed nodes
Also, we were running the retry on the `SAME` pool which for each retry will
be the scheduler pool. Since the error path of the listener we use here
will do blocking operations when closing the resources used by the recovery
we can't use the `SAME` pool here since not all exceptions go to the `ActionListenerResponseHandler`
threading like e.g. `NodeNotConnectedException`.
Closes#57585
In ff9e8c622427d42a2d87b4ceb298d043ae3c4e6a we changed the format
used when serializing snapshot failures in the cluster state and
`SnapshotInfo`. This turned them from a short string holding all the
nested exception messages into a multi kb stacktrace in many cases.
This is not great if you snapshot a large number of shards that all fail
for example and massively blows up the size of the GET snapshots response
if there are snapshots with failures in there.
This change reverts to the format used for exceptions before the above commit.
Also, this change short circuits logging and serialization of the failure
for an aborted snapshot where we don't care about the specific message at all
and aligns the message to "aborted" in all cases (current if we aborted before any IO,
it would have been "aborted" and an exception when aborting later during IO).
Previously, hidden indices were not included in snapshots by default, unless
specified using one of the usual methods for doing so: naming indices directly,
using index patterns starting with a ., or specifying expand_wildcards to
a value that includes hidden (e.g. all or hidden,open).
This commit changes the default expand_wildcards value to include hidden
indices.
Fixed two newly introduced issues with rollover:
1. Using auto-expand replicas, rollover could result in unexpected log
messages on future indexes.
2. It did a reroute and other heavy work on the network thread.

Allow for optimistic concurrency control during ingest by checking the
sequence number and primary term. This is accomplished by defining
_if_seq_no and _if_primary_term in the pipeline, similarly to _version
and _version_type.

The shrink action creates a shrunken index with the target number of shards.
This makes the shrink action data stream aware. If the ILM managed index is
part of a data stream the shrink action will make sure to swap the original
managed index with the shrunken one as part of the data stream's backing
indices and then delete the original index.

This commit fixes a bug on the composite aggregation when the index
is sorted and the primary composite source needs to round values (date_histo).
In such case, we cannot take into account the subsequent sources even if they
match the index sort because the rounding of the primary sort value may break
the original index order.
Fixes#57849
This deprecates `Rounding#round` and `Rounding#nextRoundingValue` in
favor of calling
```
Rounding.Prepared prepared = rounding.prepare(min, max);
...
prepared.round(val)
```
because it is always going to be faster to prepare once. There
are going to be some cases where we won't know what to prepare *for*
and in those cases you can call `prepareForUnknown` and stil be faster
than calling the deprecated method over and over and over again.
Ultimately, this is important because it doesn't look like there is an
easy way to cache `Rounding.Prepared` or any of its precursors like
`LocalTimeOffset.Lookup`. Instead, we can just build it at most once per
request.

Currently it is possible for a transient network error to disrupt the
start recovery request from the remote to source node. This disruption
is racy with the recovery occurring on the source node. It is possible
for the source node to finish and clear its recovery. When this occurs,
the recovery cannot be reestablished and the "no two start" assertion
is tripped. This commit fixes this issue by allowing two starts if the
finalize request has been received.
Fixes#57416.
Currently, the translog ops request is reentrent when there is a mapping
update. The impact of this is that a translog ops ends up waiting on the
pre-existing listener and it is never completed. This commit fixes this
by introducing a new code path to avoid the idempotency logic.
The action name is passed to the `ChannelListener` and is used for
logging purposes. Currently, we are using the incorrect action name for
the translog ops listener. This commit fixes the issue.
This reworks string flavored implementations of the `terms` aggregation
to save memory when it is under another bucket by dropping the usage of
`asMultiBucketAggregator`.
Adds assertions to Netty to make sure that its threads are not polluted by thread contexts (and
also that thread contexts are not leaked). Moves the ClusterApplierService to use the system
context (same as we do for MasterService), which allows to remove a hack from
TemplateUgradeService and makes it clearer that applying CS updates is fully executing under
system context.
Currently we check that exceptions are the same in the recovery request
tracker test. This is inconsistent because the future wraps the
exception in a new instance. This commit fixes the test by comparing a
random exception message.
Fixes#57199
In #57701 we changed mappings merging so that duplicate fields specified in mappings caused an
exception during validation. This change makes the same exception thrown when metadata fields are
duplicated. This will allow us to be strict currently with plans to make the merging more
fine-grained in a later release.
Currently a network disruption will fail a peer recovery. This commit
adds network errors as retryable actions for the source node.
Additionally, it adds sequence numbers to the recovery request to
ensure that the requests are idempotent.
Additionally it adds a reestablish recovery action. The target node
will attempt to reestablish an existing recovery after a network
failure. This is necessary to ensure that the retries occurring on the
source node provide value in bidirectional failures.
Fix broken numeric shard generations when reading them from the wire
or physically from the physical repository.
This should be the cheapest way to clean up broken shard generations
in a BwC and safe-to-backport manner for now. We can potentially
further optimize this by also not doing the checks on the generations
based on the versions we see in the `RepositoryData` but I don't think
it matters much since we will read `RepositoryData` from cache in almost
all cases.
