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.
In some cases our Windows builds fail due to long path names that arise
from a combination of long build job names plus long sub-project
names. While newer versions of Windows can handle long paths, invoking
batch scripts longer than 260 characters via cmd.exe is still
problematic. This leads to failing integration tests because we can not
run the commands to install plugins, create the keystore, and start the
node. This commit handles this by converting all paths on Windows used
to start an Elasticsearch node to short path names.

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.

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
587409e893 introduced a bug where an example of the format of a request which contained placeholder values was attempted to be tested. This change adds `NOTCONSOLE` to that snippet as the immediately following snippet tests a concrete example.
220212dd69 introduced a bug because the test substitution was looking for `otherhost` where the snippet contained `oldhost`. This change fixes the substitution
By making RestHighLevelClient Closeable, its close method will close the internal low-level REST client instance by default, which simplifies the way most users interact with the high-level client.
Its constructor accepts now a RestClientBuilder, which clarifies that the low-level REST client is internally created and managed.
It is still possible to provide an already built `RestClient` instance, but that can only be done by subclassing `RestHighLevelClient` and calling the protected constructor that accepts a `RestClient`. In such case a consumer has also to be provided, which controls what has to be done when the high-level client gets done.
Closes#26086
* 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
There was some confusion about the fact that tokens emitted from a Pattern
Capture Token Filter are treated as synonyms when used to analyze a search
query. This commit adds an explanation to the note in the docs to emphasize this
behaviour.
Closes#25746
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.

When Elasticsearch starts up, it tries to create a keystore if one does
not exist; this is so the keystore can be seeded. With the RPM and
Debian packages, the keystore would be located in
/etc/elasticsearch. This configuration directory is typically not
writable by the elasticsearch user so the Elasticsearch process will not
have permission to create the keystore. Instead, the RPM and Debian
packages should create the keystore (if it does not exist) on package
installation. This commit enables these packages to do that in the
post-install routines.

We need to check if JAVA_TOOL_OPTIONS, and JAVA_OPTS are set, and if
ES_PATH_CONF is not set. However, if these variables are defined and
contain quotes, the current mechanism busts on them. Instead, we should
use safer mechanism for checking if these variable are defined or
not. This commit does that.

We use `:` for cross-cluster search (eg `cluster:index`), therefore, we should
not allow the ambiguity when allowing cluster or index names.

We previously explicitly set the HOSTNAME environment variable so that
${HOSTNAME} could be used a placeholder for defining the node.name in
elasticsearch.yml. We removed explicitly setting this because bash
defines HOSTNAME. The problem is that bash defines HOSTNAME as a bash
variable, not as an environment variable. Therefore, to restore the
previous behavior, we export the bash value for HOSTNAME as an
environment variable named HOSTNAME. For consistency between Windows and
the Unix-like systems, we also define HOSTNAME with a value equal to the
environment variable COMPUTERNAME on Windows.
