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.
Closes#49703
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.

Does not reuse substring from SQL due to the difference in semantics and
the accepted arguments.
Currently it is missing full integration tests as, due to the usage of
scripting, requires an actual integration test against a proper cluster (and
likely its own QA project).
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.

With the upgrade to Lucene 8.5, LatLonShape field has support for distance queries. This change implements this new feature and removes the limitation.
This reverts commit 7636930ceb.
There is some randomization in the YAML test suite which means we can't check
for exact xcontentlocation in the deprecation warning headers.
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
It's simple to deprecate a field used in an ObjectParser just by adding deprecation
markers to the relevant ParseField objects. However, 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 it appears. This commit adds the parent object parser
name and XContentLocation to these deprecation messages.
Slow log's routing value when null was causing ESLogMessage.asJson
method to throw Null Pointer Exception. This should be fixed in
ESLogMessage as well as prevent passing that key at all.
This only happens in 8 because of previous refactoring #46702
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).
The AuditTrailService has historically been an AuditTrail itself, acting
as a composite of the configured audit trails. This commit removes that
interface from the service and instead builds a composite delegating
implementation internally. The service now has a single get() method to
get an AuditTrail implementation which may be called. If auditing is not
allowed by the license, an empty noop version is returned.
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.
* 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.

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.
Given that types have been removed entirely in 8.0, we don't need a detailed page
explaining what they are and why they are going away. This commit replaces the
page with a short paragraph saying that types are no longer supported, and a link
to the [removal-of-types] page in 7x

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.
Note - this re-introduces: commit: 4f48e053f9
with some additional fixes.
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.
Follows: #52822Fixes: #53496
This change adapts the serialization checks to 7.7.0 in order to cope with #53659.
Note that this commit also disables the bwc tests temporarily in order to be able to
merge #53659 first.
