In case multiple completion suggestion entries have the same score and
surface form, the order in which such options will be returned is
currently not deterministic.
With this commmit we introduce tie-breaking for such situations, based
on shard id, index name, index uuid and doc id like we already do for
ordinary search hits. With this change we also make shardIndex
mandatory when sorting and comparing completion suggestion options,
which was previously only needed later when fetching hits).
Also, we need to make sure shardIndex is properly set when merging
completion suggestions coming from multiple clusters in
`SearchResponseMerger`
This change adds two new cluster privileges:
* manage_data_frame_transforms
* monitor_data_frame_transforms
And two new built-in roles:
* data_frame_transforms_admin
* data_frame_transforms_user
These permit access to the data frame transform endpoints.
(Index privileges are also required on the source and
destination indices for each data frame transform, but
since these indices are configurable they it is not
appropriate to grant them via built-in roles.)
* Soften redundant cast to allow use of `DeterministicTaskQueue` in this class for #39504
* Remove two redundant variables and lower visibility in two possible spots
* Make field `final`
Currently Fuzziness#asDistance(String) doesn't work for custom AUTO values. If
the fuzziness is AUTO, the method returns the correct edit distance to use,
depending on the input string, but for custom AUTO values it currently always
returns an edit distance of 1. Correcting this and adding unit and integration
tests to catch these cases.
Closes#39614
Today we have no chance to fetch actual segment stats for segments that
are currently unloaded. This is relevant in the case of frozen indices.
This allows to monitor how much memory a frozen index would use if it was
unfrozen.
This is a backport of #39631

This change adds support for the concurrent refresh of access
tokens as described in #36872
In short it allows subsequent client requests to refresh the same token that
come within a predefined window of 60 seconds to be handled as duplicates
of the original one and thus receive the same response with the same newly
issued access token and refresh token.
In order to support that, two new fields are added in the token document. One
contains the instant (in epoqueMillis) when a given refresh token is refreshed
and one that contains a pointer to the token document that stores the new
refresh token and access token that was created by the original refresh.
A side effect of this change, that was however also a intended enhancement
for the token service, is that we needed to stop encrypting the string
representation of the UserToken while serializing. ( It was necessary as we
correctly used a new IV for every time we encrypted a token in serialization, so
subsequent serializations of the same exact UserToken would produce
different access token strings)
This change also handles the serialization/deserialization BWC logic:
In mixed clusters we keep creating tokens in the old format and
consume only old format tokens
In upgraded clusters, we start creating tokens in the new format but
still remain able to consume old format tokens (that could have been
created during the rolling upgrade and are still valid)
When reading/writing TokensInvalidationResult objects, we take into
consideration that pre 7.1.0 these contained an integer field that carried
the attempt count
Resolves#36872
The match interval builder analyses input text and converts it to an IntervalSource, and as such
may generate token streams with stopwords. This commit deals with these by using the extend
factory to cover the gaps produced by these stopwords so that phrase and ordered queries work
correctly.
Previously, the security index could be wrongfully recreated. This might
happen if the index was interpreted as missing, as in the case of a fresh
install, but the index existed and the state did not yet recover.
This fix will return HTTP SERVICE_UNAVAILABLE (503) for requests that
try to write to the security index before the state has not been recovered yet.
Investigating how to make DeleteExpiredDataIT faster, it was
revealed that the security audit trail threads were quite hot.
Disabling that seems to be helping quite a bit with making this
test faster. This commit also unmutes the test to see how it goes
with the audit trail disabled.

With this commit we provide more info in an existing error message that is
raised when the file `jvm.dll` cannot be found on Windows when installing
Elasticsearch as a service.
`TopDocsCollectorContext` can already shortcut hit counts on `match_all` and `term` queries when there are no deletions.
This change adds this ability for `exists` queries if the index doesn't have deletions and fields are indexed.
Closes#37475
While serializing custom objects, the length of the list is computed after
filtering out the unsupported objects but while writing objects the filter
is not applied thus resulting in writing unsupported objects which will fail
to deserialize by the receiever. Adding the condition to filter out unsupported
custom objects.
Since #39006 we should be able to complete a peer-recovery without
waiting for pending indexing operations. Thus, the assertion in
testDoNotWaitForPendingSeqNo should be updated from false to true.
Closes#39510
MIN/MAX on strings are supported and are implemented with
TopAggs FIRST/LAST respectively, but they cannot operate on
`text` fields without underlying `keyword` fields => inexact.
Follows: #39427
`enum` is a single option from a known list of `options`
`list` is an array of unknown values
`flags` are multiple options from a list of known `options`.
We don't support the `flags` type but a `list` with `options` acts as one. This is already the case for other API's taking metric such as `node.stats.json`.
watcher.stats behaves the same as other API's as `metrics` and as such accepts the following `GET _xpack/watcher/stats/queued_watches,current_watches`
(cherry picked from commit 4c00a025b8ac9b397b27c4ae2f799553d6499412)
ML has historically used doc as the single mapping type but reindex in 7.x
will change the mapping to _doc. Switching to the typeless APIs handles
case where the mapping type is either doc or _doc. This change removes
deprecated typed usages.
This is now possible as Lucene's `TotalHits` implements `equals`/`hashcode`,
all the other methods can be in-lined in `SearchHits` instead, no need for
a specific wrapper class.
* Introduce Safer Chaining of Listeners
* The motivation here is to make reasoning about chains of `ActionListener` a little easier, by providing a safe method for nesting `ActionListener` that guarantees that a response is never dropped. Also, it dries up the code a little by removing the need to repeat `listener::onFailure` and `listener.onResponse` over and over.
* Refactored a number of obvious/easy spots to use the new listener constructor
Zen1IT#testFreshestMasterElectedAfterFullClusterRestart fails sometimes because
we request the cluster state before state recovery has completed, and therefore
obtain the default value for the setting we're relying on.
Confusingly, we were starting out by setting this setting to its default value,
so the test looked like it was failing because of a production bug. This commit
avoids this confusion in future by setting it to a non-default value at the
start of the test.
Fixes#39586.
This commit adds the following:
- more tests to IndicesServiceCloseTests, one of them found a bug in the order
in which `IndicesQueryCache#onClose` and
`IndicesService.indicesRefCount#decRef` are called.
- made `IndicesQueryCache.stats2` a synchronized map. All writes to it are
already protected by the lock of the Lucene cache, but the final read from
an assertion in `IndicesQueryCache#close()` was not so this change should
avoid any potential visibility issues.
- human-readable `toString`s to make debugging easier.

This cleans up the Engine implementation by separating the sequence number generation from the
planning step in the engine, to avoid for the planning step to have any side effects. This makes it
easier to see that every sequence number is properly accounted for.
* Removed request builder. From 7.0, request builders are no longer used.
* Use RestStatusToXContentListener instead of custom RestBuilderListener in the rest action.
* Changed a few public constructor's and constants' visibility from public to package protected.
(these are only used internally, so no need to for public visibility)
* methods to run bin script
* Add support for specifying and installing plugins
* Add OS specific distirbution support
* Add test to verify plugin installed
* Remove use of Gradle internal OperatingSystem
* Un-mute and fix BuildExamplePluginsIT
There doesn't seem to be anything wrong with the test iteself.
I think the failure were CI performance related, but while it was muted,
some failures managed to sneak in.
Closes#38784
