Reindex would use timeValueNanos(System.nanoTime()). The intended use
for TimeValue is as a duration, not as absolute time. In particular,
this could result in negative TimeValue's, being unsupported in #53913.
Modified to use the bare long nano-second value.

This commit ensures that we don't use the non-deterministic canReturnNullResponseIfMatchNoDocs
boolean in the cache key of the ShardSearchRequest. The value of this boolean has no influence
on the cacheability of the request.
Closes#32827
Today we log `failed to execute pipeline for a bulk request` at `ERROR` level
if an attempt to run an ingest pipeline fails. A failure here is commonly due
to an `EsRejectedExecutionException`. We also feed such failures back to the
client and record the rejection in the threadpool statistics.
In line with #51459 there is no need to log failures within actions so noisily
and with such urgency. It is better to leave it up to the client to react
accordingly. Typically an `EsRejectedExecutionException` should result in the
client backing off and retrying, so a failure here is not normally fatal enough
to justify an `ERROR` log at all.
This commit reduces the log level for this message to `DEBUG`.
Fixes an issue where the elasticsearch-node command-line tools would not work correctly
because PersistentTasksCustomMetaData contains named XContent from plugins. This PR
makes it so that the parsing for all custom metadata is skipped, even if the core system would
know how to handle it.
Closes#53549
This removes some more ceremony when declaring agg parsers. You no
longer need a static `parse` method, instead you can just make the
`PARSER` public in most cases.
There are still a few aggs with the `parse` method, but those `parse`
methods are a little more complex to untangle.
Currently the remote info api has added a number of possible fields
(proxy, num_socket_connections, etc) that are available in proxy mode.
These fields are not aligned with what the settings are named. This
commit modifies this API to align with the settings.
Wildcard queries on keyword fields get normalized, however this normalization
step should exclude the two special characters * and ? in order to keep the
wildcard query itself intact.
Closes#46300
The snapshot stats response list of snapshot statuses is not ordered according to the
given list of snapshot names so randomly we could mix up snapshot1 and snapshot2
when asserting on the stats.
Fixed by getting each snapshot's stats individually.
Closes#54034
This commit changes the pre_filter_shard_size default from 128 to unspecified.
This allows to apply heuristics based on the request and the target indices when deciding
whether the can match phase should run or not. When unspecified, this pr runs the can match phase
automatically if one of these conditions is met:
* The request targets more than 128 shards.
* The request contains read-only indices.
* The primary sort of the query targets an indexed field.
Users can opt-out from this behavior by setting the `pre_filter_shard_size` to a static value.
Closes#39835
I created this bug today in #53793. When a `DelayableWriteable` that
references an existing object serializes itself it wasn't taking the
version of the node on the other side of the wire into account. This
fixes that.
Today when cluster.remote.connect is set to false, and some aspect of
the codebase tries to get a remote client, today we return a no such
remote cluster exception. This can be quite perplexing to users,
especially if the remote cluster is actually defined in their cluster
state, it is only that the local node is not a remote cluter
client. This commit addresses this by providing a dedicated error
message when a remote cluster is not available because the local node is
not a remote cluster client.
This commit removes the configuration time vs execution time distinction
with regards to certain BuildParms properties. Because of the cost of
determining Java versions for configuration JDK locations we deferred
this until execution time. This had two main downsides. First, we had
to implement all this build logic in tasks, which required a bunch of
additional plumbing and complexity. Second, because some information
wasn't known during configuration time, we had to nest any build logic
that depended on this in awkward callbacks.
We now defer to the JavaInstallationRegistry recently added in Gradle.
This utility uses a much more efficient method for probing Java
installations vs our jrunscript implementation. This, combined with some
optimizations to avoid probing the current JVM as well as deferring
some evaluation via Providers when probing installations for BWC builds
we can maintain effectively the same configuration time performance
while removing a bunch of complexity and runtime cost (snapshotting
inputs for the GenerateGlobalBuildInfoTask was very expensive). The end
result should be a much more responsive build execution in almost all
scenarios.

This moves the pipeline aggregation validation from the data node to the
coordinating node so that we, eventually, can stop sending pipeline
aggregations to the data nodes entirely. In fact, it moves it into the
"request validation" stage so multiple errors can be accumulated and
sent back to the requester for the entire request. We can't always take
advantage of that, but it'll be nice for folks not to have to play
whack-a-mole with validation.
This is implemented by replacing `PipelineAggretionBuilder#validate`
with:
```
protected abstract void validate(ValidationContext context);
```
The `ValidationContext` handles the accumulation of validation failures,
provides access to the aggregation's siblings, and implements a few
validation utility methods.
If a setting is touched during bootstrap before logging is configured,
and that setting uses a byte size value, the deprecation logger for
ByteSizeValue will be initialized. However, this means a logger will be
configured before log4j is initialized, which we reject at startup. This
commit puts this deprecation logger in a holder pattern so that it is
not initialized until first use, which will happen after logging is
configured.
Benchmarking showed that the effect of the ExitableDirectoryReader
is reduced considerably when checking every 8191 docs. Moreover,
set the cancellable task before calling QueryPhase#preProcess()
and make sure we don't wrap with an ExitableDirectoryReader at all
when lowLevelCancellation is set to false to avoid completely any
performance impact.

* Get Async Search: omit _clusters section when empty (#53907)
The _clusters section is omitted by the search API whenever no remote clusters are searched. Async search should do the same, but Get Async Search returns a deserialized response, hence a weird `_clusters` section with all values set to `0` gets returned instead. In fact the recreated Clusters object is not the same object as the EMPTY constant, yet it has the same content.
This commit addresses this by changing the comparison in the `toXContent` method to not print out the section if the number of total clusters is `0`.
* Async search: remove version from response (#53960)
The goal of the version field was to quickly show when you can expect to find something new in the search response, compared to when nothing has changed. This can also be done by looking at the `_shards` section and `num_reduce_phases` returned with the search response. In fact when there has been one or more additional reduction of the results, you can expect new results in the search response. Otherwise, the `_shards` section could notify of additional failures of shards that have completed the query, but that is not a guarantee that their results will be exposed (only when the following partial reduction is performed their results will be available).
That said this commit clarifies this in the docs and removes the version field from the async search response
* Async Search: replicas to auto expand from 0 to 1 (#53964)
This way single node clusters that are green don't go yellow once async search is used, while
all the others still have one replica.
* [DOCS] address timing issue in async search docs tests (#53910)
The docs snippets for submit async search have proven difficult to test as it is not possible to guarantee that you get a response that is not final, even when providing `wait_for_completion=0`. In the docs we want to show though a proper long-running query, and its first response should be partial rather than final.
With this commit we adapt the docs snippets to show a partial response, and replace under the hood all that's needed to make the snippets tests succeed when we get a final response. Also, increased the timeout so we always get a final response.

Use sequence numbers and force merge UUID to determine whether a shard has changed or not instead before falling back to comparing files to get incremental snapshots on primary fail-over.
The test in CloseWhileRelocatingShardsIT failed recently
multiple times (3) when waiting for initial indices to be
become green. Looking at the execution logs from #53544
it appears at the very beginning of the test and when
the WindowsFS file system is picked up (which is known
to slow down tests).
This commit simply increases the timeout for the first
ensureGreen() to 60 seconds. If the test continues to fail,
we might want to test a larger timeout or disable
WindowsFS for this test.
Closes#53544
This commits adds a data stream feature flag, initial definition of a data stream and
the stubs for the data stream create, delete and get APIs. Also simple serialization
tests are added and a rest test to thest the data stream API stubs.
This is a large amount of code and mainly mechanical, but this commit should be
straightforward to review, because there isn't any real logic.
The data stream transport and rest action are behind the data stream feature flag and
are only intialized if the feature flag is enabled. The feature flag is enabled if
elasticsearch is build as snapshot or a release build and the
'es.datastreams_feature_flag_registered' is enabled.
The integ-test-zip sets the feature flag if building a release build, otherwise
rest tests would fail.

This commit changes the Transforms notifications index to be hidden
index, with a hidden alias.
This commit also removes the temporary hack in
MetaDataCreateIndexService that prevents deprecation warnings for known
dot-prefixed index names which are not hidden/system indices, as this
was the last index pattern to need that hack.
We mark cluster states persisted on master-ineligible nodes as
potentially-stale using the voting configuration `{STALE_STATE_CONFIG}` which
prevents these nodes from being elected as master if they are restarted as
master-eligible. Today we do not handle this special voting configuration
differently in the `ClusterFormationFailureHandler`, leading to a mysterious
message `an election requires a node with id [STALE_STATE_CONFIG]` if the
election does not succeed.
This commit adds a special case description for this situation to explain
better why this node cannot win an election.
Closes#53734
The test was randomly and very rarely failing due to generating the same sort
key for multiple records, which was making order of these records in the results
nondeterministic. While investigating the test I also found that the data wasn't
generated in the way that matches the actual data. Normally, the order of
documents in hits and scoreDocs in InternalTopHits should be the same. However,
in the test only scoreDocs were sorted which was cause very confusing failure
messages. This commit fixes this issue as well.
Fixes#53676
Today in the `CoordinatorTests` each node uses multiple threadpools. This is
mostly fine as they are almost completely stateless, except for the
`ThreadContext`: by using multiple threadpools we cannot make assertions that
the thread context is/isn't preserved as we expect. This commit consolidates
the threadpool instances in use so that each node uses just one.
TermsLookup in master no longer accepts a type parameter. We should emit
a deprecate warning in 7.x when a terms lookup requests includes type to prepare
users for its removal.

It's simple to deprecate a field used in an ObjectParser just by adding deprecation
markers to the relevant ParseField objects. The warnings themselves don't currently
have any context - they simply say that a deprecated field has been used, but not
where in the input xcontent it appears. This commit adds the parent object parser
name and XContentLocation to these deprecation messages.
Note that the context is automatically stripped from warning messages when they
are asserted on by integration tests and REST tests, because randomization of
xcontent type during these tests means that the XContentLocation is not constant
The retention lease syncs need to occur under the system context,
because they are internal actions executed on behalf of the user. Today
we are relying on this happening for background syncs by virtue of the
fact that the context the syncs are created under is the system
context. This is due to these occurring on the cluster state applier
thread. However, there are situations where this does not hold such as
when a timed out cluster state publication occurs, and the node where
the shard is allocated is the elected master node. In that case, the
context will be empty due to the fact that we do not reschedule
publication under the system context. Currently, doing so runs us into
some troubles with losing the existing context, possibly dropping
deprecation headers. We could copy that context over when marking the
current context as the system context, but the implications of that
require some more investigation. For now, we explicitly mark the
retention lease syncs as executing under the system context, as this is
situation that we can reason about.
The JodaCompatibleZonedDateTime is a compatibility object that unions
Joda's DateTime and Java's ZonedDateTime, meant for use in scripts. When
it was added, we serialized the JCZDT as a Joda DateTime so that when
sending to older nodes they could still read the object. However, on
newer nodes, we continued also reading this as a Joda DateTime. This
commit changes the read side to form a JCZDT.

testIndexHasDuplicateData tests were failing ocassionally,
due to approximate calculation of BKDReader.estimatePointCount,
where if the node is Leaf, the number of points in it
was (maxPointsInLeafNode + 1) / 2.
As DEFAULT_MAX_POINTS_IN_LEAF_NODE = 1024, for small indexes
used in tests, the estimation could be really off.
This rewrites tests, to make the max points in leaf node to
be a small value to control the tests.

This commit makes a number of improvements when importing the
Elasticsearch project into IntelliJ IDEA. Specifically:
- Contributing documentation has been updated to reflect that the
'idea' task should no long be used and Gradle project import is
instead the officially supported way of setting up the project.
- Attempts to run the 'idea' task will result in a failure with a
message directing folks to our CONTRIBUTING.md document.
- The project JDK is explicit set rather that using whatever JAVA_HOME
is.
- Gradle build operation delegation is disabled, and test execution is
configured to 'choose per test'.
- Gradle is configured to inherit the project JDK.
- Some code style conventions are automatically configured.
- File encoding is explicitly set to UTF-8.
- Parallel module compilation is enabled and deprecated feature
warnings are disabled.
- A remote debug run configuration using listen mode is created.
- JUnit runner is configured with required system properties.
- License headers are configured such that Apache 2 is the default
notice added to all source files with exception of source in /x-pack
which will use the Elastic license.
