The unfollow API changes a follower index into a regular index, so that it will accept write requests from clients.
For the unfollow api to work the index follow needs to be stopped and the index needs to be closed.
Closes#33931
This change introduces the indexing optimization using sequence numbers
in the FollowingEngine. This optimization uses the max_seq_no_updates
which is tracked on the primary of the leader and replicated to replicas
and followers.

This commit removes the use of ExecutableScript from watcher in favor of
custom script contexts for both watcher condition scripts and transform
scripts.
Fixes the equals and hash function to ignore the order of aggregations to ensure equality after serialization
and deserialization. This ensures storing configs with aggregation works properly.
This also addresses a potential issue in caching when the same query contains aggregations but in
different order. 1st it will not hit in the cache, 2nd cache objects which shall be equal might end up twice in
the cache.
In order to be compatible with joda time, this adds an epoch seconds
formatter, that is able to parse floating point values.
However joda time discards the floating point values, but still parses
the data, where as this one is able to parse the whole value including
milliseconds.
The synonym filters no longer need access to the AnalysisRegistry in their
constructors, so we can remove the special-case code and move them to the
common analysis module.
This commit means that synonyms are no longer available for `server` integration tests,
so several of these are either rewritten or migrated to the common analysis module
as rest-spec-api tests
* Make sure 'ignored' and 'routing' field types inherit from StringFieldType.
* Add tests for prefix and regexp queries.
* Support prefix and regexp queries on _index fields.
This commit adds the ability to plug in compilation of custom contexts
in mock script engine. This is needed for testing plugins which add
custom contexts like watcher.
Prior to this change when a pipeline processor called another
pipeline, only the stats for the first processor were recorded.
The stats for the subsequent pipelines were ignored. This change
properly accounts for pipelines irregardless if they are the first
or subsequently called pipelines.
This change moves the state of the stats from the IngestService
to the pipeline itself. Cluster updates are safe since the pipelines
map is atomically swapped, and if a cluster update happens
while iterating over stats (now read directly from the pipeline)
a slightly stale view of stats may be shown.
Recently we introduced the settings cluster.remote to take the place of
search.remote for configuring remote cluster connections. We made this
change due to the fact that we have generalized the remote cluster
infrastructure to also be used within cross-cluster replication and not
only cross-cluster search. For backwards compatibility, when we made this
change, we allowed that cluster.remote would fallback to
search.remote. Alas, the initial change for this contained a bug for
handling the proxy and seeds settings. The bug for the seeds settings
arose because we were manually iterating over the concrete settings only
for cluster.remote seeds but not for search.remote seeds. This commit
addresses this by iterating over both cluster.remote seeds and
search.remote seeds. Additionally, when checking for existence of proxy
settings, we have to not only check cluster.remote proxy settings, but
also fallback to search.remote proxy settings. This commit addresses
both issues, and adds tests for these situations.
* Handle MatchNoDocsQuery in span query wrappers
This change adds a new SpanMatchNoDocsQuery query that replaces
MatchNoDocsQuery in the span query wrappers.
The `wildcard` query now returns MatchNoDocsQuery if the target field is not
in the mapping (#34093) so we need the equivalent span query in order to
be able to pass it to other span wrappers.
Closes#34105
EngineSearcher can be easily folded into Engine.Searcher which removes
a level of inheritance that is necessary for most of it's subclasses.
This change folds it into Engine.Searcher and removes the dependency on
ReferenceManager.
* This should surface what errors are thrown on CI
and in org.elasticsearch.transport.RemoteClusterConnection.ConnectHandler#collectRemoteNodes
(the sequence of caught error in the last catch block and moving on to the next seed node
seems to be the only path by which the errors logged in #33756 could come about)

This commit adds "engine is closed" as an expected failure message.
This change is due to #33967 in which we might access a closed engine on
promotion.

This change is related to #33903 that ports the DocStats
simplification to the master branch. This change builds the docStats
in the ReadOnlyEngine from the last committed segment infos rather than
the reader.

Although we allow to index BigInteger and BigDecimal into a keyword
field, source filtering on these fields would fail
as XContentBuilder was not able to deserialize BigInteger and BigDecimal
to json.
This modifies XContentBuilder to allow to handle BigInteger and
BigDecimal.
Closes#32395
This commits creates a DateMathParser interface, which is already
implemented for both joda and java time. While currently the java time
DateMathParser is not used, this change will allow a followup which will
create a DateMathParser from a DateFormatter, so the caller does not
need to know the internals of the DateFormatter they have.
Previously, unmapped aggs try to delegate reduction to a sibling agg that is
mapped. That delegated agg will run the reductions, and also
reduce any pipeline aggs. But because delegation comes before running
pipelines, the unmapped agg _also_ tries to run pipeline aggs.
This causes the pipeline to run twice, and potentially double it's output
in buckets which can create invalid JSON (e.g. same key multiple times)
and break when converting to maps.
This fixes by sorting the list of aggregations ahead of time so that mapped
aggs appear first, meaning they preferentially lead the reduction. If all aggs
are unmapped, the first unmapped agg simply creates a new unmapped object
and returns that for the reduction.
This means that unmapped aggs no longer defer and there is no chance for
a secondary execution of pipelines (or other side effects caused by deferring
execution).
Closes#33514
`SingleFieldsVisitor` is meant to load a single stored field but it
manages to be quite complex to reason about because it inherits from our
"basic" `FieldsVisitor` which is designed to load many fields. This
breaks that inheritance and adds logic to `SingleFieldsVisitor` so it can
be properly stand alone. While this amounts to more lines of code they
ought to be significantly easier to reason about.
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
This commit removes the sysprop controlling whether ctx is in params for
update scripts and replaces it with use of the new ParameterMap, which
outputs a deprecation warning whenever params.ctx is used.
Today query parsers throw TooManyClauses exception when a query creates
too many clauses. However graph phrase queries do not respect this limit.
This change adds a protection against crazy expansions that can happen when
building a graph phrase query. This is a temporary copy of the fix available
in https://issues.apache.org/jira/browse/LUCENE-8479 but not merged yet.
This logic will be removed when we integrate the Lucene patch in a future
release.

Today `SearchAsyncActionTests#testFanOutAndCollect` uses a simple `HashMap` for
the `nodeToContextMap` variable, which is then accessed from multiple threads
without, apparently, explicit synchronisation. This provides an explanation for
the test failure identified in #29242 in which `.toString()` returns `"[]"`
just before `.isEmpty` returns `false`, without any concurrent modifications.
This change converts `nodeToContextMap` to a `newConcurrentMap()` so that this
cannot occur. It also fixes a race condition in the detection of double-calling
the subsequent search phase.
Closes#29242.
We start tracking max seq_no_of_updates on the primary in #33842. This
commit replicates that value from a primary to its replicas in replication
requests or the translog phase of peer-recovery.
With this change, we guarantee that the value of max seq_no_of_updates
on a replica when any index/delete operation is performed at least the
max_seq_no_of_updates on the primary when that operation was executed.

We currently fallback to local indices whenever a remote cluster is not found, as there may still be indices / aliases with the same name. Such behaviour is lenient but needs to be kept for backwards compatibility. Clarified that in the code so we don't forget.

It mistakenly uses the Elasticsearch major version instead of the Lucene major
version. I noticed it when backporting, it is not noticeable on master because
the only two Lucene versions that are supported, 7 and 8, encode norms the same
way, unlike Lucene 6.
Today, TransportService uses System.currentTimeMillis() to get the current time
to report on things like timeouts, and enqueues lambdas for future execution.
However, in tests it is useful to be able to fake out the current time and to
see what all these enqueued lambdas are really for. This change alters the
situation so that we can obtain the time from the more easily-faked
ThreadPool#relativeTimeInMillis(), and implements some friendlier toString()
methods on the various Runnables so we can see what they are later.
As far as I can tell this guard against fragile analyzers is no longer relevant, since
we stopped setting special analyzers on numeric fields (3bf6f4). Instead of removing
the guard completely, I opted to keep a check for untokenized + unnormalized fields
to avoid going through the analysis process unnecessarily.
My motivation for simplifying this check is that I'd like to add support for
`split_queries_on_whitespace` to the new 'queryable object' fields. As it stands, I would
have to add a dedicated instanceof check for the new mapper, which is not optimal.
This commit introduces an AbstractSimpleSecurityTransportTestCase for
security transports. This classes provides transport tests that are
specific for security transports. Additionally, it fixes the tests referenced in
#33285.
* TESTS: Make score Float#NaN when there is no max score
Fixes test failure due to maxScore set to Float#MinValue instead
on Float#NaN. In addition the initial value for maxScore is set to
Float#NEGATIVE_INFINITY so it is an illegal value.
Closes#33993
When executing a cross-cluster search, we need to search against all local indices (and no remote indices) in case no indices are specified. Also, if only remote indices are specified, no local indices will be queried. We previously added empty local indices whenever they were not present in the map of the grouped indices, then we would act differently later based on the extracted remote indices. Instead, we now add the empty array for local indices only in case we need to search all local indices; the entry for local indices is not added when local indices should not be searched. This way the grouped indices reflect reality and provide a better indication of what indices will be searched.
