The unified highlighter returns the first sentence of the text when number_of_fragments
is set to 0 (full highlighting). This is a legacy of the removed postings highlighter
that was based on sentence break only. This commit changes this behavior in order
to respect the provided no_match_size value when number_of_fragments is set to 0.
This means that the behavior will be consistent for any value of the number_of_fragments option.
Closes#41066

* Adjust S3Fixture to accept both path styles for bulk deletes since the S3 SDK uses both during our ITs
* Closes#40250
Today the blended term query detects if a term exists in a field by looking at the term statistics in the index.
However the value to indicate that a term has no occurence in a field have changed in Lucene. A non-existing term now returns
a doc and total term frequency of 0. Because of this disrepancy the blended term query picks 0 as the minimum frequency for a term
even if other fields have documents for this terms. This confuses the term queries that the blending creates since some of them
contain a custom state that indicates a frequency of 0 even though the term has some occurence in the field. For these terms an exception
is thrown because the term query always checks that the term state's frequency is greater than 0 if there are documents associate to it.
This change fixes this bug by ignoring terms with a doc freq of 0 when the blended term query picks the minimum term frequency among the
requested fields.
Closes#41118
`TransportReplicationAction.AsyncPrimaryAction#createReplicatedOperation`
exists so it can be overridden in tests. This commit re-works these tests to
use a real `ReplicationOperation` and inlines the now-unnecessary method.
Relates #40706.
Today we fail to join a Zen2 cluster if the cluster UUID does not match our
own, but we do not perform the same validation when joining a Zen1 cluster.
This means that a Zen2 node will pass join validation and be added to a Zen1
cluster but will reject all cluster states from the master.
Relates #37775
Currently we throw an error when a range querys minimum value exceeds the
maximum value due to the fact that they are neighbouring values and both upper
and lower value are excluded from the interval.
Since this is a condition that the user usually doesn't specify conciously (at
least in the case of float and double values its difficult to see which values
are adjacent) we should ignore those "wrong" intervals and create a
MatchNoDocsQuery in those cases.
We should still throw errors with an actionable message if the user specifies
the query interval in a way that min value > max value. This PR adds those
checks and tests for those cases.
Closes#40937
Traditionally we have [recommended](https://www.elastic.co/guide/en/beats/filebeat/current/monitoring.html) that Beats send their monitoring data to the **production** Elasticsearch cluster. Beats do this by calling the `POST _monitoring/bulk` API. When Security is enabled this API call requires the `cluster:admin/xpack/monitoring/bulk` privilege. The built-in `beats_system` role has this privilege.
[Going forward](https://github.com/elastic/beats/pull/9260), Beats will be able to send their monitoring data directly to the **monitoring** Elasticsearch cluster. Beats will do this by calling the regular `POST _bulk` API. When Security is enabled this API call requires the `indices:data/write/bulk` privilege. Further, the call has to be able to create any indices that don't exist.
This PR expands the built-in `beats_system` role's privileges. Specifically, it adds index-level `write` and `create_index` privileges for `.monitoring-beats-*` indices.
This will allow Beats users to continue using the `beats_system` role for the new direct monitoring route when Security is enabled.
This is related to #36652. We intend to deprecate a number of transport
settings in 7.x and remove them in 8.0. This commit removes the string
usages of these settings.
Usage of the ILM Move to Step API can result in some very odd
situations, and for diagnosing problems arising from these situations it
would be nice to have a record of when this API was called with what
parameters.
Also, adds a dedicated logger for TransportMoveToStepAction,
rather than using the (deprecated) inherited one.
This PR makes a few clarifications to the docs for the `enabled` setting:
- Replace references to 'mapping type' with 'mapping' or 'mapping definition'.
- In code examples, clarify that the disabled fields have type `object`.
- Add a section on how disabled fields can hold non-object data.
This commit removes xpack dependencies of many xpack qa modules.
(for some qa modules this will require some more work)
The reason behind this change is that qa rest modules should not depend
on the x-pack plugins, because the plugins are an implementation detail and
the tests should only know about the rest interface and qa cluster that is
being tested.
Also some qa modules rely on xpack plugins and hlrc (which is a valid
dependency for rest qa tests) creates a cyclic dependency and this is
something that we should avoid. Also Eclipse can't handle gradle cyclic
dependencies (see #41064).
* don't copy xpack-core's plugin property into the test resource of qa
modules. Otherwise installing security manager fails, because it tries
to find the XPackPlugin class.
With the 7.0.0 release, we switched to download the packages instead of
using locally built ones.
This PR fixes the artifact names to include the architecture as
introduced in the 7.0.0 release.
This section should be at the same sub-level as other sections in the
auto date-histogram docs, otherwise it is rendered on to another page
and is confusing for users to understand what it's in reference to.
Pipelines require single-valued agg or a numeric to be returned.
If they don't get that, they throw an exception. Unfortunately, this
exception text is very confusing to users because it usually arises
from pathing "through" multiple terms aggs. The final target is a numeric,
but it's the intermediary aggs that cause the problem.
This commit adds the current agg name to the exception message
so the user knows which "level" is the issue.
Values higher than 100% are now allowed to accommodate use
cases where swapping has been determined to be acceptable.
Anomaly detector jobs only use their full model memory
during background persistence, and this is deliberately
staggered, so with large numbers of jobs few will generally
be persisting state at the same time. Settings higher than
available memory are only recommended for OEM type
situations where a wrapper tightly controls the types of
jobs that can be created, and each job alone is considerably
smaller than what each node can handle.
Full text queries ignore unmapped fields since https://github.com/elastic/elasticsearch/issues/41022
even if all fields in the query are unmapped.
This change makes sure that we ignore unmapped fields only if they are mixed
with mapped fields and returns a MatchNoDocsQuery otherwise.
Closes#41022
This commit adds an OpenID Connect authentication realm to
elasticsearch. Elasticsearch (with the assistance of kibana or
another web component) acts as an OpenID Connect Relying
Party and supports the Authorization Code Grant and Implicit
flows as described in http://ela.st/oidc-spec. It adds support
for consuming and verifying signed ID Tokens, both RP
initiated and 3rd party initiated Single Sign on and RP
initiated signle logout.
It also adds an OpenID Connect Provider in the idp-fixture to
be used for the associated integration tests.
This is a backport of #40674
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.
Relates to #16347
The following phrase causes confusion:
> Alternatively the IP addresses or hostnames (if node name defaults to the
> host name) can be used.
This change clarifies the conditions under which you can use a hostname, and
adds an anchor to the note introduced in (#41137) so we can link directly to it
in conversations with users.
It is possible for the watches tracked by ScheduleTriggerEngineMock to
get out of sync with the Watches in the ScheduleTriggerEngine
production code, which can lead to watches failing to run.
This commit:
1. Changes TimeWarp to try to run the watch on all schedulers, rather than stopping after one which claims to have the watch registered. This reduces the impact of desynchronization between the mocking code and the backing production code.
2. Makes ScheduleTriggerEngineMock respect pauses of execution again. This is necessary to prevent duplicate watch invocations due to the above change.
3. Tweaks how watches are registered in ScheduleTriggerEngineMock to prevent race conditions due to concurrent modification.
4. Tweaks WatcherConcreteIndexTests to use TimeWarp instead of waiting for watches to be triggered, as TimeWarp is more reliable and accomplishes the same goal.
For pattern "n:localhost" PatternRule#isLocalhost() matches
any local address, loopback address.
[Note: I think for "localhost" this should not consider IP address
as a match when they are bound to network interfaces. It should just
be loopback address check unless the intent is to match all local addresses.
This class is adopted from Netty3 and I am not sure if this is intended
behavior or maybe I am missing something]
For now I have fixed this assuming the PatternRule#isLocalhost check is
correct by avoiding use of local address to check address denied.
Closes#40194
Backport of (#41087)
* Use environment settings instead of state settings for Watcher config
Prior to this we used the settings from cluster state to see whether ILM was
enabled of disabled, however, these settings don't accurately reflect the
`xpack.ilm.enabled` setting in `elasticsearch.yml`.
This commit changes to using the `Environment` settings, which correctly reflect
the ILM enabled setting.
Resolves#41042
ILM poll intervals of less than 1 second will not be allowed, so add a
deprecation check for that.
Even though I'm pretty sure zero production clusters will do this, it's
best to be thorough.
Fixes rendering the `version_qualified` attribute in the docs. This
attribute includes `-SNAPSHOT` but does not include `-alpha` or `-beta`
and represents the `version` field as returned by `GET /` or
`GET /_cat/plugins`. Without this change we just drop the entire line on
the floor rather than render it so the output looks bad.
Fixes some documentation urls in the rest-api-spec. Some of these URLs
pointed to 404s and a few others pointed to deprecated documentation
when we have better documentation now. I'm not consistent about `master`
vs `current` because we're not consistent in other places and I think we
should solve all of those at once with something a little more
automatic.
Instead of allowing docker-compose to rebuild it.
With this change we tag the image with a test label, and use that
in the testing as this is simpler that dealing with a dynamically
generated docker-compose file.
When a polygon contains a self-intersection due to have twice the same point in no-consecutive position, the polygon builder tries to split the polygon. During the split one of the polygons become invalid as it is not closed and an error is thrown which is not related to the real issue.
We detect this situation now and throw a more meaningful error.
disallow partial results in rollup and data frame, after this change the client throws an error directly
replacing the previous runtime exception thrown, allowing better error handling in implementations.
Today a new replica of a closed index does not have a safe commit
invariant when its engine is opened because we won't initialize the
global checkpoint on a recovering replica until the finalize step. With
this change, we can achieve that property by creating a new translog
with the global checkpoint from the primary at the end of phase 1.
This helps avoid memory issues when computing deep sub-aggregations. Because it
should be rare to use sub-aggregations with significant terms, we opted to always
choose breadth first as opposed to exposing a `collect_mode` option.
Closes#28652.
