This change skips the rest test in `rest-api-spec/test/indices.shrink/20_source_mapping.yml` as it currently fails because if we don’t expect the deprecation warning the normal rest tests fail because they get a warning they don’t expect but if we do expect the deprecation warning the mixed cluster tests fail because they don’t get a warning which they expected.
This commit fixes an issue with the REST test that the shrink API
ignores templates. The problem is that we have to use a BWC version of
the API (for the BWC tests) but this raises deprecation warnings. This
commit adds an expectation for these deprecation warnings.
When sending replica requests for replication operations, we skip
sending the request to pre-6.0 nodes for operations that such nodes
would not be aware of (e.g., the background global checkpoint sync, or
the primary/replica resync) since they would not know what to do with
these requests. Yet, we simulate that we received responses from these
nodes. Today, this is done by simulating that they sent us that their
local checkpoint is unassigned sequence number. However, for pre-6.0
nodes we have introduced a special local checkpoint used in the global
checkpoint tracker for such nodes and that is what we should use here
too. This commit fixes this issue.

This commit adjusts the skip version for a shrink index test that
ensures that a shrunken index ignores templates; the version can be
adjusted after the fix was backported targeting 5.6.0 and later.

#25521 changed channel closing to be handled async on anything but transport stop. This means it may take a while before
calling `connection.close()` and the node being removed from the `connectedNodes` list (but the connection is immediately unusuable).

The alpha2 docs is built out of master which may make users think that the high level client was already released as part of alpha2 which it was not. This note should clarify that the client will be released with 6.0.0-beta1
This commit changes the default heap size to 1 GB. Experimenting with
elasticsearch is often done on laptops, and 1 GB is much friendlier to
laptop memory. It does put more pressure on the gc, but the tradeoff is
a smaller default footprint. Users running in production can (and
should) adjust the heap size as necessary for their usecase.
Currently replication and recovery are both coordinated through the latest cluster state available on the ClusterService as well as through the GlobalCheckpointTracker (to have consistent local/global checkpoint information), making it difficult to understand the relation between recovery and replication, and requiring some tricky checks in the recovery code to coordinate between the two. This commit makes the primary the single owner of its replication group, which simplifies the replication model and allows to clean up corner cases we have in our recovery code. It also reduces the dependencies in the code, so that neither RecoverySourceXXX nor ReplicationOperation need access to the latest state on ClusterService anymore. Finally, it gives us the property that in-sync shard copies won't receive global checkpoint updates which are above their local checkpoint (relates #25485).
This adds a section about how to add aggregations to the SearchSourceBuilder and how
to retrieve them from a SearchRepsonse to the documentation for the high level rest client.
The Filtered Query has been deprecated in favour of the Bool Query with a filter context. However, this deleted page for the Filtered Query is often ranked highly in search results when searching for documentation on "filtered queries". Often people just copy the first code snippet they see, which in this case is the INCORRECT syntax (the correct syntax follows). I think reordering the examples would help avoid a lot of confusion (I have seen people make this same mistake 3 times now)
Adding a comment to indicate that the first example shouldn't be used
When parsing indices options from REST, we parse the optional parameters that are supported at REST (ignore_unavailable, allow_no_indices and expand_wildcards) and we provide the API default values for all the other (internal) options so that they are set to the new indices options while parsing. The `ignoreAliases` option was forgotten though, which means that whenever you pass in any index option at REST to the delete index API, you get to delete aliases like it was supported before (as ignoreAliases gets set to false like in all the other APIs).
Added unit tests for IndicesOptions parsing from REST parameters, and yaml tests for the delete index API.
This change refactors the query_string query to analyze the query text around logical operators of the query string the same way than a match_query/multi_match_query.
It also adds a type parameter that can be used to change the way multi fields query are built the same way than a multi_match query does.
Now that these queries share the same behavior regarding text analysis, some parameters are obsolete and have been deprecated:
split_on_whitespace: This setting is now ignored with a deprecation notice
if it is used explicitely. With this PR The query_string always splits on logical operator.
It simplifies the understanding of the other parameters that can have different meanings
depending on the value of split_on_whitespace.
auto_generate_phrase_queries: This setting is now ignored with a deprecation notice
if it is used explicitely. This setting only makes sense when the parser splits on whitespace.
use_dismax: This setting is now ignored with a deprecation notice
if it is used explicitely. The tie_breaker parameter is sufficient to handle best_fields/most_fields.
Fixes#25574
With cross cluster search we can potentially proxy `can_match` requests
to nodes that don't have the endpoint. This might not cause any problem
from a functional perspecitve but will cause ugly error messages on
the target node. This commit will cause an IAE if we try to talk to an
incompatible node via a proxy.

It was brought up that our current client artifacts have generic names like 'rest' that may cause conflicts with other artifacts.
This commit renames:
- rest -> elasticsearch-rest-client
- sniffer -> elasticsearch-rest-client-sniffer
- rest-high-level -> elasticsearch-rest-high-level-client
A couple of small changes are also preparing the high level client for its first release.
Closes#20248
The slop parameter defaults to 0 in the Lucene SpanNearQuery, so we can set it
to this default value also and don't have to require it being specified in the
query when using the Rest API. Leaving `slop` a ctro arg in the Java API as it
should normally be specified and we can keep it `final` that way.
Closes#25642
A shrunk index should ignore anything from templates and instead take
its mappings, aliases, and settings from the original index, plus any
new settings and aliases passed in with the shrink request. This commit
causes this to be the case.

We already use a per JVM port range in MockTransportService. Yet,
it's possible that if we are executing in the JVM with ordinal 0 that
other clusters reuse ports from the mock transport service and some tests
try to simulate disconnects etc. By using a non-defautl port range (starting at 10300)
we prevent internal test clusters from reusing any of the mock impls ports

Today if we search across a large amount of shards we hit every shard. Yet, it's quite
common to search across an index pattern for time based indices but filtering will exclude
all results outside a certain time range ie. `now-3d`. While the search can potentially hit
hundreds of shards the majority of the shards might yield 0 results since there is not document
that is within this date range. Kibana for instance does this regularly but used `_field_stats`
to optimize the indexes they need to query. Now with the deprecation of `_field_stats` and it's upcoming removal a single dashboard in kibana can potentially turn into searches hitting hundreds or thousands of shards and that can easily cause search rejections even though the most of the requests are very likely super cheap and only need a query rewriting to early terminate with 0 results.
This change adds a pre-filter phase for searches that can, if the number of shards are higher than a the `pre_filter_shard_size` threshold (defaults to 128 shards), fan out to the shards
and check if the query can potentially match any documents at all. While false positives are possible, a negative response means that no matches are possible. These requests are not subject to rejection and can greatly reduce the number of shards a request needs to hit. The approach here is preferable to the kibana approach with field stats since it correctly handles aliases and uses the correct threadpools to execute these requests. Further it's completely transparent to the user and improves scalability of elasticsearch in general on large clusters.
This commit enables management of the main Elasticsearch log files
out-of-the-box by the following changes:
- compress rolled logs
- roll logs every 128 MB
- maintain a sliding window of logs
- remove the oldest logs maintaining no more than 2 GB of compressed
logs on disk

This commit removes the environment variable ES_JVM_OPTIONS that allows

This commit reverts a rename of the systemd packaging tests. The rename
was done locally to speed up iteration of testing some changes against
systemd but was not reverted before pushing. This commit reverts this
change.
Requests that execute a stored script will no longer be allowed to specify the lang of the script. This information is stored in the cluster state making only an id necessary to execute against. Putting a stored script will still require a lang.
* Changes DocValueFieldsFetchSubPhase to reuse doc values iterators for multiple hits
Closes#24986
* iter
* Update ScriptDocValues to not reuse GeoPoint and Date objects
* added Javadoc about script value re-use
* Enable doc values for range fields by default.
* Store ranges in a binary format that support multi field fields.
* Added BinaryDocValuesRangeQuery that can query ranges that have been encoded into a binary doc values field.
* Wrap range queries on a range field in IndexOrDocValuesQuery query.
Closes#24314
This method does exactly what getHits() does and is used in only a few places,
so it can safely be removed. It seems to be a left-over from when
InternalSearchHits was folded into the SearchHits interface, which didn't
contain this method.
