* Remove the _all metadata field
This change removes the `_all` metadata field. This field is deprecated in 6
and cannot be activated for indices created in 6 so it can be safely removed in
the next major version (e.g. 7).
The `locale` field of `date` fields accepts almost any string and unknown
locales are simply ignored, which is trappy. We should fail on unknown languages
or countries.
This commit also makes `-` an accepted separator in addition to `_` since `-`
is the recommended separator (https://tools.ietf.org/html/rfc5646#section-2.1).
`_` is probably still worth supporting since it is the separator used by
`Locale#toString()`.
In order to know, when the script compilation limit has kicked in,
this commit adds a counter in the script stats to expose that
information.
So far the only way to find out about this was to check the logs
or check out responses of individual requests.
At current, we do not feel there is enough of a reason to shade the low
level rest client. It caused problems with commons logging and IDE's
during the brief time it was used. We did not know exactly how many
users will need this, and decided that leaving shading out until we
gather more information is best. Users can still shade the jar
themselves. For information and feeback, see issue #26366.
Closes#26328

This commit removes the streams test for access after closing the bytes
stream. Output streams being closed mean they can no longer be written
to, but other methods to retrieve side state of the stream can still
make sense, such as bytes() in this case.

This allows plugins to plug rescore implementations into
Elasticsearch. While this is a fairly expert thing to do I've
done my best to point folks to the QueryRescorer as one that at
least documents the tradeoffs that it makes. I've attempted to
limit the API surface area by removing `SearchContext` from the
exposed interface, instead exposing just the IndexSearcher and
`QueryShardContext`. I also tried to make some of the class names
more consistent and do some general cleanup while I was there.
I entertained the notion of moving the `QueryRescorer` to module.
After all, it'd be a wonderful test to prove that you can plug
rescore implementation into Elasticsearch if the only built in
rescore implementation is in the module. But I decided against it
because the new module would require a client jar and it'd require
moving some more things around. I think if we really want to do
it, we should do it as a followup.
I did, on the other hand, create an "example" rescore plugin which
should both be a nice example for anyone wanting to plug in their
own rescore implementation and servers as a good integration test
to make sure that you can indeed plug one in.
Closes#26208
This change rewrite phrase query built on a field indexed without positions
to match_no_docs query when the `lenient` option is set to true.
This change affects all full text queries.
There is a group of five settings relating to raw tcp configurations
(no_delay, buffer sizes, etc) that we have for the http transport. These
currently live in the netty module. As they are unrelated to netty
specifically, this commit moves these settings to the
`HttpTransportSettings` class in core.
This commit removes the keystore creation on elasticsearch startup, and
instead adds a plugin property which indicates the plugin needs the
keystore to exist. It does still make sure the keystore.seed exists on
ES startup, but through an "upgrade" method that loading the keystore in
Bootstrap calls.
closes#26309
This commit renames the TransportResyncReplicationAction name to be an internal action as this is
not an action that should be invoked by a user, but is instead internal to the operation of the
system.
* Check bucket metric ages point to a multi bucket agg
This adds a validation step to the BucketMetricsPipelineAggregationBuilder which ensure that the first aggregation in the `buckets_path` is a multi-bucket aggregation. It does this using a new `MultiBucketAggregationBuilder` marker interface.
The change also moves the validate of pipeline aggregations to the `AggregatorFactories.build()` method so the validate can inspect sibling `AggregatorBuilder` objects rather than `AggregatorFactory` objects. Further it removes the validate from `AggregatorFactory` since this was never implemented and since aggregators only depend on their own internal state and not on other aggregators they should be validated ideally at setter time but in rare case where this is not possible the validation should be done in the `AggregationBuilder.build()` step.
Closes#25775
Move validate stage to happen during AggregatorFactories.Builder.build
Also removes validate method from normal aggs since it was never used.
* review comment fix
* Accept an array of field names and boosts in the index.query.default_field setting
This commit allows to define an array of field names and boosts for the index setting `index.query.default_field`.
The format is equivalent to the `fields` options of the full text search queries (e.g. field_name^boost).
This commit also makes this setting dynamically updatable.
Fixes#25946
* More XContent migrations
* Removes ToXContentToBytes
* Adds toString to classes that used to extend ToXContentToBytes
* use XContentHelper
* more review comments
* prettify tostring output
The test verifies that search on the primary works by executing a search with preference _primary. If the primary is relocating, however, it
does not take the primary relocation target into account. The test only makes sense, however, if balancing is not happening yet, i.e., the
cluster is not green.
The javadoc tool on JDK 9 has issues with the combination of anonymous classes and varargs parameters.
This commit simply refactors a few anonymous classes to private inner classes.
This PR begins the long journey to deprecating Streamable.
The idea here is to add additional method signatures that
support Writeable.Reader, so that the work to migrate objects TransportMessage to
implement Writeable and not Streamable.
One example conversion is done in this PR: SimulatePipelineRequest.
This commit extracts the inner query in the ESToParentBlockJoinQuery for highlighting.
This query has been added in 5.4 and breaks plain highlighting on nested queries.
Highlighters that use postings or term vectors are not affected because they can't highlight nested documents correctly.
Fixes#26230
This commit makes the security code aware of the Java 9 FilePermission changes (see #21534) and allows us to remove the `jdk.io.permissionsUseCanonicalPath` system property.
Gives allocation commands from the cluster reroute API
the ability to provide messages to be logged once the
cluster state change has been committed.
The purpose of this change is to create a record in the
logs when allocation commands which could potentially
be destructive are applied. The allocate_empty_primary
and allocate_stale_primary commands are the only ones
that currently provide log messages.
Closes#22821
* Deprecate global_ordinals_hash and global_ordinals_low_cardinality
This change deprecates the `global_ordinals_hash` and `global_ordinals_low_cardinality` and
makes the `global_ordinals` execution hint choose internally if global ords should be remapped or use the segment ord directly.
These hints are too sensitive and expert to be exposed and we should be able to take the right decision internally based on the agg tree.
Currently the `precision` parameter must be a precision level
in the range of [1,12]. In #5042 it was suggested also supporting
distance units like "1km" to automatically approcimate the needed
precision level. This change adds this support to the Rest API by
making use of GeoUtils#geoHashLevelsForPrecision.
Plain integer values without a unit are still treated as precision
levels like before. Distance values that are too small to be represented
by a precision level of 12 (values approx. less than 0.056m) are
rejected.
Closes#5042
The `from` search parameter cannot really be used in scrolled searches. This
commit adds a check for this case to the SearchRequest#validate() method so we
can reported it as an error rather than silently ignoring it.
Closes#9373
This change is a continuation of #25726 that aligns field expansions for the simple_query_string with the query_string and multi_match query.
The main changes are:
* For exact field name, the new behavior is to rewrite to a matchnodocs query when the field name is not found in the mapping.
* For partial field names (with * suffix), the expansion is done only on keyword, text, date, ip and number field types. Other field types are simply ignored.
* For all fields (*), the expansion is done on accepted field types only (see above) and metadata fields are also filtered.
The use_all_fields option is deprecated in this change and can be replaced by setting `*` in the fields parameter.
This commit also changes how text fields are analyzed. Previously the default search analyzer (or the provided analyzer) was used to analyze every text part
, ignoring the analyzer set on the field in the mapping. With this change, the field analyzer is used instead unless an analyzer has been forced in the parameter of the query.
Finally now that all full text queries can handle the special "*" expansion (`all_fields` mode), the `index.query.default_field` is now set to `*` for indices created in 6.
This commit converts script query to use a new FilterScript context. The
new context returns a boolean, so the error that would have previously
happened at runtime if a non boolean was returned would now happen at
script compilation. Also, the leniency of supporting returning a number
and 0 mapping to false, non-zero to true is gone, but it was never
documented. With the new context compilation will now also fail if
special variables are used at compilation time, instead of runtime, eg
ctx.
Right now we use a custom future for the CloseFuture associated with a
channel. This is because we need special unwrapping logic to ensure that
exceptions from a future failure are a certain type (opposed to an
UncategorizedException). However, the current version is limiting
because we can only attach one listener.
This commit changes the CloseFuture to extend the
PlainListenableActionFuture. This change allows us to attach multiple
listeners.
When slices is set as auto, there's an additional network call
needed for the reindex tasks to know how to rethrottle. Sometimes
the rethrottle action happens before the reindex task is fully
initialized, so in the test we wait for the task to be ready.
This commit also adds some safeguards to ensure that
cancel and rethrottle operations are handled correctly
Closes#26192
If we do not have permissions to write the keystore, an unclear access
denied exception is thrown. This commit catches this exception so that
we can decorate it with a friendlier error message.
Relates #26284
We use `:` for cross-cluster search (eg `cluster:index`), therefore, we should
not allow the ambiguity when allowing cluster or index names.
Relates to #23892
We already added the functionality to create a new keystore on startup
in #26126 but apparently missed to persist the keystore. This change adds
peristence and adds a test for the boostrap loading.
Today a `ClusterState.Custom` can be fetched by a transport client and
leaks to the user even if the classes are private etc since the serialized
bytes can be reconstructed. This change adds an option to customs to mark
them as private such that our clusterstate action will never leak it.
The AwaitsFix issue has been closed as the deleting an index and recreating with same name will give the
shard a fresh folder to be written to (based on the index uuid).
Due to the weird way of structuring the serialization code in AcknowledgedRequest, many request types forgot to properly serialize the request timeout, for example "index deletion", "index rollover", "index shrink", "putting pipeline", and other requests. This means that if those requests were not directly sent to the master node, the acknowledgement timeout information would be lost (and the default used instead).
Some requests also don't properly expose the timeout mechanism in the REST layer, such as put / delete stored script. This commit fixes all that.
