With this change, we will always return true for can_match requests on
idle search shards; otherwise, some shards will never get refreshed if
all search requests perform the can_match phase (i.e., total shards >
pre_filter_shard_size).

This commit refactors all spatial Field Mappers to a common
AbstractGeometryFieldMapper that implements shared parameter functionality
(e.g., ignore_malformed, ignore_z_value) and provides a common framework for
overriding type parsing, and building in xpack. Common shape functionality is
implemented in a new AbstractShapeGeometryFieldMapper that is reused and
overridden in GeoShapeFieldMapper, GeoShapeFieldMapperWithDocValues,
LegacyGeoShapeFieldMapper, and ShapeFieldMapper. This abstraction provides a
reusable foundation for adding new xpack features; such as coordinate reference
system support.
This commit removes some code duplication in the CCR non-compliance
tests by refactoring an assertion method so that it can be used in both
tests that are present there.
Firstly, backport the use of tini as the Docker entrypoint. This was supposed
to have been done following #50277, but was missed. It isn't a direct backport
as this branch will continue using root as the initial Docker user.
Secondly, backport #55491 to use the official checksums when downloading tini.
Makes the following changes to the `stemmer` token filter docs:
* Adds detailed analyze example
* Rewrites parameter definitions
* Adds custom analyzer example
* Adds a `language` value for the `estonian` stemmer
* Reorders the `language` values to show recommended algorithms first,
followed by other values alphabetically
Adds conceptual documentation for stemming, including:
* An overview of why stemming is helpful in search
* Algorithmic vs. dictionary stemming
* Token filters used to control stemming, such as `stemmer_override`, `keyword_marker`, and `conditional`
The example looks the same as in the previous section although it should use the
"fuzziness" parameter. This seems to be okay on 6.8 and master and was probably
only forgotten to port to 7.x branches.
Since #55580 we've introduced a new format for parsing progress
from the data frame analytics process. As the process is now
writing out progress in this new way, we can remove the parsing
of the old format.
Backport of #55711
If we choose to read from two random positions that are 1024 bytes apart then
this counts as a contiguous read for stats purposes, failing this test. This
commit ensures that we always perform a non-contiguous read.
`SearchableSnapshotDirectoryStatsTests#testCachedBytesReadsAndWrites` asserts
that each write takes one clock tick, but we now permit concurrent reads and
writes so each write might take longer. This commit relaxes the assertion to
match.

improve tests related to stopping using a client that answers and can be
synchronized with the test thread in order to test special situations
relates #55011
This commit fixes reproducible test failures with the
SSLReloadDuringStartupIntegTests on the 7.x branch. The failures only
occur on 7.x due to the existence of the transport client and its usage
in our test infrastructure. This change removes the randomized usage of
transport clients when retrieving a client from a node in the internal
cluster. Transport clients do not support the reloading of files for
TLS configuration changes but if we build one from the nodes settings
and attempt to use it after the files have been changed, the client
will not know about the changes and the TLS connection will fail.
Closes#55524
License state is currently made up of boolean methods that check whether
a particular feature is allowed by the current license state. Each new
feature must copy/past boiler plate code. While that has gotten easier
with utilities like isAllowedByLicense, this is still more cumbersome
than should be necessary. This commit adds a general purpose isAllowed
method which takes a new Feature enum, where each value of the enum
defines the minimum license mode and whether the license must be active
to be allowed. Only security features are converted in this PR, in order
to keep the commit size relatively small. The rest of the features will
be converted in a followup.
This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user. This is technically
required today already, but throws an exception much deeper
in the agg framework and has a very unintuitive error for the user
(as well as eating more resources instead of failing early)
The (de)serialization code of the async search response
cannot handle exceptions that extend ElasticsearchException (e.g. ScriptException).
This commit fixes this bug by serializing the error with the more generic
StreamInput#writeException.
EQL will require very similar functionality to async search. This PR refactors
AsyncSearchIndexService to make it reusable for EQL.

This commit refactors geo_shape doc values, fielddata, and utility classes from
the single mapper package in x-pack spatial plugin to a package structure that
is consistent with the server module.
Previously audit messages were indexed when datafeeds that were
assigned to a node were stopped, but not datafeeds that were
unassigned at the time they were stopped.
This change adds auditing for the unassigned case.

This commit adds `runtime.java` as a system property in our
nonInputProperties so that it will be available to be printed
upon test failure by ReproduceInfoPrinter.
Adds a important admonition to the EQL syntax page noting that
the equal (`==`) operator should not be used to match `text` field
values.
Relates to #52709 and #53020
We are using `FORCE_STALE_PRIMARY_INSTANCE` in instance equality checks `==`
but were creating new instances of `ExistingStoreRecoverySource` when reading
from the wire. This could break these checks in corner cases, causing
`org.elasticsearch.cluster.routing.allocation.IndexMetadataUpdater#shardStarted`
to not remove the force allocation fake id when starting a shard.
Closes#55513
While we were catching `TaskCancelledException` while we wait for
reindexing to complete, we missed the fact that this exception
may be wrapped in a multi-node cluster. This is the reason
we may still fail the task when stop is called while reindexing.
Some times we're lucky and the exception is thrown by the same
node that runs the job. Then the exception is not wrapped and
things work fine. But when that is not the case the exception is
wrapped, we fail to catch it, and set the task to failed.
The fix is to simply unwrap the exception when we check it it
is `TaskCancelledException`.
Closes#55068

The CacheFile.fileLock() method is used to acquire a lock
on a cache file so that the file can't be deleted (or its file
handle closed) during the execution of a read or a write
operation.
Today this lock is obtained by first acquiring the eviction
lock (the write lock of the readwrite lock), then by checking
if the cache file is evicted and the file channel still open,
and finally by obtaining the file lock (the read lock of the
readwrite lock). Acquiring the read lock while the eviction
lock is held ensures that the cache file eviction cannot
start in the meanwhile. But eviction starts (and terminations)
also acquire the eviction lock; and this lock cannot be
obtained while a read lock is held (the write lock of a
readwrite lock is exclusive).
If we were acquiring a read lock and checking the eviction
flag and file channel existence while holding the read lock
we know that no eviction can start or finish until the
read lock is released.
Currently QueryStringQueryParser already checks if the field limit is breached
at construction time, which e.g. leads to errors if the default field is set to
"*" or the default isn't used and there are more fields than the limit, even if the
query itself does not use all these fields.
This change moves this check to happen after query parsing. QueryStringQueryParser now
keeps track of the fields that are actually resolved while parsing. The size of
that set is later used to check against the limit set by the
`indices.query.bool.max_clause_count` setting.

Replace calls to deprecate(String,Object...) with deprecateAndMaybeLog(...),

The Kibana CSV export feature uses a non-standard timestamp format.
This change adds it to the formats the find_file_structure endpoint
recognizes out-of-the-box, to make round-tripping data from Kibana
back to Kibana via CSV files easier.
Fixes#55586
This commit changes the way that V2 index, component, and request mappings are merged. Specifically:
- Fields are merged in a "replacement" manner, meaning that the entire definition is replaced rather
than merging the interior configuration
- Mapping metadata (all fields outside of `properties`) are merged recursively.
The merging for V1 templates does not change.

A JSON schema was recently introduced for the REST API specification. #54252
This PR introduces a 3rd party validation tool to ensure that the
REST specification conforms to the schema.
The task is applied to the 3 projects that contain REST API specifications.
The plugin wires this task into the precommit commit task, and should be
considered as part of the public API for the build tools for any plugin
developer to contribute their plugin's specification.
An ignore parameter has been introduced for the task to allow specific
file to be ignored from the validation. The ignored files in this PR
will soon get issues logged and a link so they can be fixed.
Closes#54314
Out of the box "access granted" audit events are not logged
for system users. The list of system users was stale and included
only the _system and _xpack users. This commit expands this list
with _xpack_security and _async_search, effectively reducing the
auditing noise by not logging the audit events of these system
users out of the box.
Closes#37924
The testPerformAction test has been failing periodically due to
how Hamcrest's containsStringIgnoringCase does not lowercase using
the same Locale set in the test infrastructure.
This commit falls back to explicitly lowercasing using the root
locale
This commit adds a new GeoShapeBoundsAggregator to the spatial plugin and registers it with the GeoShapeValuesSourceType. This enables geo_bounds aggregations on geo_shape fields
This change fixes problem with updating Index Templates V2.
Validatation added in #54933 didn't filter list of conflicting templates correctly so
new template was always clashing with itself unless patterns were not changed completely.
