Today the `GroupedActionListener` accepts a `defaults` parameter but all
callers pass an empty list. Also it is permitted to pass an empty group but
this is trappy because the delegated listener is never be called in that case.
This commit removes the `defaults` parameter and forbids an empty group.
As we are moving to single type indices,
we need to address this change in security-related indexes.
To address this, we are
- updating index templates to use preferred type name `_doc`
- updating the API calls to use preferred type name `_doc`
Upgrade impact:-
In case of an upgrade from 6.x, the security index has type
`doc` and this will keep working as there is a single type and `_doc`
works as an alias to an existing type. The change is handled in the
`SecurityIndexManager` when we load mappings and settings from
the template. Previously, we used to do a `PutIndexTemplateRequest`
with the mapping source JSON with the type name. This has been
modified to remove the type name from the source.
So in the case of an upgrade, the `doc` type is updated
whereas for fresh installs `_doc` is updated. This happens as
backend handles `_doc` as an alias to the existing type name.
An optional step is to `reindex` security index and update the
type to `_doc`.
Since we do not support the security audit log index,
that template has been deleted.

* Optimize Bulk Message Parsing and Message Length Parsing
* findNextMarker took almost 1ms per invocation during the PMC rally track
* Fixed to be about an order of magnitude faster by using Netty's bulk `ByteBuf` search
* It is unnecessary to instantiate an object (the input stream wrapper) and throw it away, just to read the `int` length from the message bytes
* Fixed by adding bulk `int` read to BytesReference
This commit renames the retention lease setting
index.soft_deletes.retention.lease so that it is under the namespace
index.soft_deletes.retention_lease. As such, we rename the setting to
index.soft_deletes.retention_lease.period.
This commit adds a new build type (together with deb/rpm/tar/zip) to
represent the official Docker images. This build type will be displayed
in APIs such as the main and nodes info APIs.
Previously, Watcher only attached its listener to indices that started
with the prefix `.watches`, which causes Watcher to silently fail to
schedule newly created Watches if the `.watches` alias is redirected to
an index that does not start with `.watches`.
Watcher now attaches the listener to all indices, so that Watcher can
respond to changes in which index has the `.watches` alias.
Also adjusts the tests to randomly use non-prefixed concrete indices
for .watches and .triggered_watches.
This is related to #35975. It adds documentation on the remote recovery
process. Additionally, it adds documentation about the various settings
that can impact the process.
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.
