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.

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

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.
This commit adds a keystore.seed setting that is automatically
generated when the ES keystore is created. This setting may be used by
plugins as a secure, random value. This commit also auto creates the
keystore upon startup to ensure the new setting is always available.
For the document field equals and hash code tests, we try to mutate the
document field to intentionally produce a document field not equal to
our provided one. We do this by randomly choosing a document field that
has either
- a randomly chosen field name and the same field value as the provided
document field
- a randomly chosen field value and the same field value as the
provided document field
If we are unlucky, it can be that the document field chosen by this
method can be equal to the provided document field. In this case, our
test will fail because the mutation really should be not equal. In this
case, we should simply try the other mutation. Note that random document
field produced by the second method can be equal to the provided
document because it has the same field name and we can get unlucky with
our randomly chosen field values. It is not the case that the random
document field produced by the first method can be equal to the provided
document field; this is because the current implementation guarantees
that the field name length will be different guaranteeing that we have a
different field name. Nevertheless, we fix the issue here by checking
that our random choice gives us a non-equal document field, and assert
that if we got unlucky the other one will work for us.
In a few places we need to lazy initialize static deprecation
loggers. This is needed to avoid touching logging before logging is
configured, but deprecation loggers that are used in foundational
classes like settings and parsers would be initialized before logging is
configured. Previously we used a lazy set once pattern which is fine,
but there's a simpler approach: the holder pattern.

This commits changes the keystore cli add commands to prompt for
creating the keystore if it does not exist. This will make it easier on
users starting out, not having to run a separate command for creation.
An array of values is required because there is no default (or
reasonable way to set a default). But validation for values
only happens if it is actually set. If the values param is omitted
entirely than the agg builder will NPE.
This chance adds several random test infrastructure improvements that caused
issues in on-going developments but are generally useful. For instance is it impossible
to restart a node with a secure setting source since we close it after the node is started.
This change makes it cloneable such that we can reuse it for a restart.
Currently the `percentiles` aggregation allows specifying both possible methods
in the query DSL, but only the later one is used. This changes it to rejecting
such requests with an error. Setting the method multiple times via the java API
still works (and the last one wins).
Closes#26095
This simply removes the default identity hashcode and equals methods in InternalAggregation which where only temporarily put there while we implmeneted the methods in the subclasses.
The node setting `cluster.indices.tombstones.size` was not registered with the settings infrastructure, making it impossible for it to be set by a user.
Closes#26191
For CLI tools, we configure logging without reading the
log4j2.properties file. This because any log statements in a CLI tool
should dump to the console while reading from the log4j2.properties file
would cause them to dump whereever the log configuration there indicates
(e.g., possibly a remote machine). To do this, we added some code to the
base implementation of all CLI tools to configure logging without a
config file. This code is also executed when Elasticsearch starts up. In
the past this was fine yet we previously added detection to
Elasticsearch to find cases where we use logging before it is
configured. Because of configuring logging without a config, this means
we only catch uses of logging before the logging without config is
performed. To correct this, we enable a CLI tool to skip enabling
logging without a config and then in the Elasticsearch CLI we indeed
utilize this to skip configuring logging without a config.

The flood warning checks the wrong threshold, namely the high
watermark. This would impact any node for which the disk usage is above
the high watermark and below the flood stage watermark. This commit
fixes this so that it compares to the flood threshold.

* Rewrite range queries with open bounds to exists query
This change rewrites range query with open bounds to an exists query that should be faster to execute.
Fixes#22640
`epoch_millis` and `epoch_second` date formats truncate float values, as numbers or as strings.
The `coerce` parameter is not defined for `date` field type and this is not changing.

In reindex APIs, when using the `slices` parameter to choose the number of slices, adds the option to specify `slices` as "auto" which will choose a reasonable number of slices. It uses the number of shards in the source index, up to a ceiling. If there is more than one source index, it uses the smallest number of shards among them.
This gives users an easy way to use slicing in these APIs without having to make decisions about how to configure it, as it provides a good-enough configuration for them out of the box. This may become the default behavior for these APIs in the future.
By default we only serialize analyzers if the index analyzer is not the
`default` analyzer or if the `search_analyzer` is different from the index
`analyzer`. This raises issues with the `_all` field when the
`index.analysis.analyzer.default_search` is set, since it automatically makes
the `search_analyzer` different from the index `analyzer`. Then there are
exceptions since we expect the `_all` configuration to be empty on 6.0 indices.
Closes#26136
Today we have a `null` invariant on all `ClusterState.Custom`. This makes
several code paths complicated and requires complex state handling in some cases.
This change allows to register a custom supplier that is used to initialize the
initial clusterstate with these transient customs.
This is a safer default since sorting by sub aggregations prevents these
aggregations from being deferred. `global_ordinals_hash` will at least
make sure that we do not use memory for buckets that are not collected.
