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.
There is an assertion in ReloadAnalyzersResponse.merge that compares index names
of merged responses that was falsely using object equality instead of
String.equals(). In the past this didn't seem to matter but with changes in the
test setup we started to see failures. Correcting this and also simplifying test
a bit to be able to run it repeatedly if needed.
Backport of #53663
* [ML] only retry persistence failures when the failure is intermittent and stop retrying when analytics job is stopping (#53725)
This fixes two issues:
- Results persister would retry actions even if they are not intermittent. An example of an persistent failure is a doc mapping problem.
- Data frame analytics would continue to retry to persist results even after the job is stopped.

Prior to this commit Watcher explicitly copied test between two
projects with a copy task. This commit removes the explicit copy in favor
of adding the Watcher tests to the available restResources that may be
copied between projects.
This is how inter-project dependencies should be modeled. However, only
Watcher is included here since it is (currently) the only project with
inter-project test dependencies.
* Fix feature flag setting for ComponentTemplate APIs (#53758)
The feature flag was set for *most* of the builds, but there are a couple where it was missing.
Resolves#53708
* Add skip for older versions of ES
Today cluster states are sometimes (rarely) applied in the default context
rather than system context, which means that any appliers which capture their
contexts cannot do things like remote transport actions when security is
enabled.
There are at least two ways that we end up applying the cluster state in the
default context:
1. locally applying a cluster state that indicates that the master has failed
2. the elected master times out while waiting for a response from another node
This commit ensures that cluster states are always applied in the system
context.
Mitigates #53751
With the upgrade to Lucene 8.5, LatLonShape field has support for distance queries. This change implements this new feature and removes the limitation.
Backport to 7x

Adds conceptual docs for token graphs.
These docs cover:
* How a token graph is constructed from a token stream
* How synonyms and multi-position tokens impact token graphs
* How token graphs are used during search
* Why some token filters produce invalid token graphs
Also makes the following supporting changes:
* Adds anchors to the 'Anatomy of an Analyzer' docs for cross-linking
* Adds several SVGs for token graph diagrams
This commit disables the sort optimization added in #51852 for scroll requests.
Scroll queries keep a state per shard so we cannot modify the request on
the first round (submit).
This bug was introduced in non-released versions which is why this pr
is marked as a non-issue.
On clusters with a large number of shards, the shards limits allocation
decider can exhibit poor performance leading to timeouts applying
cluster state updates. This occurs because for every shard, we do a loop
to count the number of shards on the node, and the number of shards for
the index of the shard. This is roughly quadratic in the number of
shards. This loop is not necessary, since we already have a O(1) method
to count the number of non-relocating shards on a node, and with this
commit we add some infrastructure to RoutingNode to make counting the
number of shards per index O(1).
* Adds per context settings:
`script.context.${CONTEXT}.cache_max_size` ~
`script.cache.max_size`
`script.context.${CONTEXT}.cache_expire` ~
`script.cache.expire`
`script.context.${CONTEXT}.max_compilations_rate` ~
`script.max_compilations_rate`
* Context cache is used if:
`script.max_compilations_rate=use-context`. This
value is dynamically updatable, so users can
switch back to the general cache if desired.
* Settings for context caches take the first value
that applies:
1) Context specific settings if set, eg
`script.context.ingest.cache_max_size`
2) Correlated general setting is set to the non-default
value, eg `script.cache.max_size`
3) Context default
The reason for 2's inclusion is to allow an easy
transition for users who've customized their general
cache settings.
Using the general cache settings for the context caches
results in higher effective settings, since they are
multiplied across the number of contexts. So a general
cache max size of 200 will become 200 * # of contexts.
However, this behavior it will avoid users snapping to a
value that is too low for them.

Currently we don't send values for the `pre_filter_shard_size` and
`max_concurrent_shard_requests` SearchRequest parameters over http when using
the High Level Rest Client. This change adds these parameters to the
RequestConverters and tests.
Removes the `flat_settings` and `timeout` query parameters from the JSON
spec and asciidoc docs for the put index template API.
These parameters are not supported by the API.
This commit, built on top of #51708, allows to modify shard search requests based on informations collected on other shards. It is intended to speed up sorted queries on time-based indices. For queries that are only interested in the top documents.
This change will rewrite the shard queries to match none if the bottom sort value computed in prior shards is better than all values in the shard.
For queries that mix top documents and aggregations this change will reset the size of the top documents to 0 instead of rewriting to match none.
This means that we don't need to keep a search context open for this shard since we know in advance that it doesn't contain any competitive hit.
The highlighting phase for percolator queries currently uses some custom query
traversal logic to find all instances of PercolatorQuery in the query tree for the
current search context. This commit converts things to instead use a QueryVisitor,
which future-proofs us against new wrapper queries or queries from custom
plugins that the percolator module doesn't know about.
Some clients have problems running this test as a numeric key is treated like an array index by default.
We can work around this by renaming the aggregation key to not be a numeric.
Sometimes we want to deprecate and remove a ParseField entirely, without replacement;
for example, the various places where we specify a _type field in 7x. Currently we can
tell users only that a particular field name should not be used, and that another name should
be used in its place. This commit adds the ability to say that a field should not be used at
all.
The introduction of the ExitableDirectoryReader showed increase of
latencies for range queries using pointvalues.
Check for cancellation every 1024 docs instead of every 15 to lower
the impact of the check in query's performance.

It is useful to be able to delay state recovery until enough data nodes have
joined the cluster, since this gives the shard allocator a decent opportunity
to re-use as much existing data as possible. However we also have the option to
delay state recovery until a certain number of master-eligible nodes have
joined, and this is unnecessary: we require a majority of master-eligible nodes
for state recovery, and there is no advantage in waiting for more.
This commit deprecates the unnecessary settings in preparation for their
removal.
