Data frame task responses had logic to return a HTTP 500 status code if there was
any node or task failures even if other tasks in the same request reported correctly.
This is different to how other task responses are handled where a 200 is always
returned leaving the client should check for failures. Returning a 500 also breaks
the high level rest client so always return a 200
Closes#44011
This PR enables the indexing optimization using sequence numbers on
replicas. With this optimization, indexing on replicas should be faster
and use less memory as it can forgo the version lookup when possible.
This change also deactivates the append-only optimization on replicas.

Currently when a document misses a vector value, vector function
returns 0 as a score for this document. We think this is incorrect
behaviour.
With this change, an error will be thrown if vector functions are
used with docs that are missing vector doc values.
Also VectorScriptDocValues is modified to allow size() function,
which can be used to check if a document has a value for the
vector field.
This commit converts the ConnectionManager's openConnection and connectToNode methods to
async-style. This will allow us to not block threads anymore when opening connections. This PR also
adapts the cluster coordination subsystem to make use of the new async APIs, allowing to remove
some hacks in the test infrastructure that had to account for the previous synchronous nature of the
connection APIs.
This commit ensures that cluster state publications to self also go through the transport layer. This
allows voting-only nodes to intercept the publication to self.
Fixes an issue discovered by a test failure where a voting-only node, which was the only
bootstrapped node, would not step down as master after state transfer because publishing to self
would succeed.
Closes#43631
The count should match the number of all df-analytics that
matched the id in the request. However, we set the count
to the number of df-analytics returned which was bound to the
`size` parameter. This commit fixes this by setting the count
to the count of the `get` response.
This commit changes the way we manage refreshes in the index engines.
Instead of relying on a SearcherManager, this change uses a ReaderManager that
creates ElasticsearchDirectoryReader when needed. Searchers are now created on-demand
(when acquireSearcher is called) from the current ElasticsearchDirectoryReader.
It also slightly changes the Engine.Searcher to extend IndexSearcher in order
to simplify the usage in the consumer.
A bug was introduced in 6.6.0 when we added support for
rollup indices. Rollup caps does NOT support looking at
remote indices, consequently, since we always look up rollup
caps, the datafeed fails with an error if its config
includes a concrete remote index. (When all remote indices
in a datafeed config are wildcards the problem did not
occur.)
The rollups feature does not support remote indices, so if
there is any remote index in a datafeed config (wildcarded
or not), we can skip the rollup cap checks. This PR
implements that change.
This brings TokenizerFactory into line with CharFilterFactory and TokenFilterFactory,
and removes the need to pass around tokenizer names when building custom analyzers.
As this means that TokenizerFactory is no longer a functional interface, the commit also
adds a factory method to TokenizerFactory to make construction simpler.

This introduces a `failed` state to which the data frame analytics
persistent task is set to when something unexpected fails. It could
be the process crashing, the results processor hitting some error,
etc. The failure message is then captured and set on the task state.
From there, it becomes available via the _stats API as `failure_reason`.
The df-analytics stop API now has a `force` boolean parameter. This allows
the user to call it for a failed task in order to reset it to `stopped` after
we have ensured the failure has been communicated to the user.
This commit also adds the analytics version in the persistent task
params as this allows us to prevent tasks to run on unsuitable nodes in
the future.
This commit deprecates the `transport.profiles.*.xpack.security.type`
setting. This setting is used to configure a profile that would only
allow client actions. With the upcoming removal of the transport client
the setting should also be deprecated so that it may be removed in
a future version.
This adds the ability to execute an action for each element that occurs
in an array, for example you could sent a dedicated slack action for
each search hit returned from a search.
There is also a limit for the number of actions executed, which is
hardcoded to 100 right now, to prevent having watches run forever.
The watch history logs each action result and the total number of actions
the were executed.

All valid licenses permit security, and the only license state where
we don't support security is when there is a missing license.
However, for safety we should attach the system (or xpack/security)
user to internally originated actions even if the license is missing
(or, more strictly, doesn't support security).
This allows all nodes to communicate and send internal actions (shard
state, handshake/pings, etc) even if a license is transitioning
between a broken state and a valid state.

Document level security was depending on the shared
"BitsetFilterCache" which (by design) never expires its entries.
However, when using DLS queries - particularly templated ones - the
number (and memory usage) of generated bitsets can be significant.
This change introduces a new cache specifically for BitSets used in
DLS queries, that has memory usage constraints and access time expiry.
The whole cache is automatically cleared if the role cache is cleared.
Individual bitsets are cleared when the corresponding lucene index
reader is closed.
The cache defaults to 50MB, and entries expire if unused for 7 days.

If an item in the bulk request fails, that could be for a variety of
reasons - it may be that the underlying behaviour of security has
changed, or it may just be a transient failure during testing.
Simply asserting a `true`/`false` value produces failure messages that
are difficult to diagnose and debug. Using hamcert (`assertThat`) will
make it easier to understand the causes of failures in this test.

Typically, dense vectors of both documents and queries must have the same
number of dimensions. Different number of dimensions among documents
or query vector indicate an error. This PR enforces that all vectors
for the same field have the same number of dimensions. It also enforces
that query vectors have the same number of dimensions.

* fix org.elasticsearch.xpack.watcher.test.integration.RejectedExecutionTests (#41777)
This commit un-mutes org.elasticsearch.xpack.watcher.test.integration.RejectedExecutionTests
which was failing intermittently due to a logic bug. It is not possible to use the real
Watcher scheduler (which is needed for this test) and reliabliby count the .triggered-watches
since current count of documents in the .triggered-watches index is based on the timing of the
scheduler and the ability to delete based on the Watcher and Write thread pools.
This commit simply removes the .triggered-watch check and relies soley on the .watcher-history
index as an indication that operations that can occur when the Watcher threadpool is rejecting.

* fix unlikely bug that can prevent Watcher from restarting (#42030)
The bug fixed here is unlikely to happen. It requires ES to be started with
ILM disabled, Watcher enabled, and Watcher explicitly stopped and restarted.
Due to template validation Watcher does not fully start and can result in a
partially started state. This is an unlikely scenerio outside of the testing
framework.
Note - this bug was introduced while the test that would have caught it was
muted. The test remains muted since the underlying cuase of the random failures
has not been identified. When this test is un-muted it will now work.
Currently the repsonse of the "_reload_search_analyzer" endpoint contains the
index names and nodeIds of indices were analyzers reloading was triggered. This
change add the names of the search-time analyzers that were reloaded.

UserRoleMapper.UserData is constructed by each realm and it is used to
"match" role mapping expressions that eventually supply the role names
of the principal.
This PR filters out `null` collection values (lists and maps), for the groups
and metadata, which get to take part in the role mapping, in preparation
for using Java 9 collection APIs. It filters them as soon as possible, during
the construction.
This commit merges the `object-fields` feature branch. The new 'flattened
object' field type allows an entire JSON object to be indexed into a field, and
provides limited search functionality over the field's contents.
