Changes:
* Removes narrative around URI searches. These aren't commonly used in production. The `q` param is already covered in the search API docs: https://www.elastic.co/guide/en/elasticsearch/reference/master/search-search.html#search-api-query-params-q
* Adds a common options section that highlights narrative docs for query DSL, aggregations, multi-index search, search fields, pagination, sorting, and async search.
* Adds a `Search shard routing` page. Moves narrative docs for adaptive replica selection, preference, routing , and shard limits to that section.
* Moves search timeout and cancellation content to the `Search your data` page.
* Creates a `Search multiple data streams and indices` page. Moves related narrative docs for multi-target syntax searches and `indices_boost` to that page.
* Removes narrative examples for the `search_type` parameters. Moves documentation for this parameter to the search API docs.
Closes#60864. Tweak the JDK directories' permissions in the ES
Docker image so that ES can run under a different user and group.
These changes assume that the image is being run with bind-mounted
config, data and logs directories, and reads and writes to these
locations will still fail when both the UID and GID are not the
default. Everything should be OK when running with the default GID
of zero, however.
Report anonymous roles in response to "GET _security/_authenticate" API call when:
* Anonymous role is enabled
* User is not the anonymous user
* Credentials is not an API Key
Access the common versions map is done in a lot of places. While it can
be access through an import of VersionProperties, the vast majority of
places use it through the provided convenience property added by
BuildPlugin. This commit moves that convenience property to the base
java plugin, so further reduce dependence on the BuildPlugin.
In the past, the only way to run a local Elasticsearch build with a remote debugger was by extracting elasticsearch and passing ES_JAVA_OPTS. However, since switching to gradle, a convenience flag was added, `--debug-jvm` (which is documented elsewhere in the testings docs), when running a local elasticsearch build through gradle. This commit removes the old documentation.
There are warnings about unlicense realms when user lookup fails. This PR adds
similar warnings for when no authentication token can be extracted from the request.
Today a remote cluster connection comprises a `PING` and a `REG`
channel. The `PING` channel is only used for health checks between the
elected master and the members of its own cluster, so is unused in a
remote cluster connection. This commit removes this unused connection.
The API key document currently doesn't include the user's full_name or email attributes,
and as a result, when those attributes return `null` when hitting `GET`ing `/_security/_authenticate`,
and in the SAML response from the [IdP Plugin](https://github.com/elastic/elasticsearch/pull/54046).
This changeset adds those fields to the document and extracts them to fill in the User when
authenticating. They're effectively going to be a snapshot of the User from when the key was
created, but this is in line with roles and metadata as well.

For large responses to the get mappings request, the serialization
to XContent can be extremely slow (serializing mappings is expensive since
we have to decompress and deserialize the mapping source).
To not introduce instability on the IO thread handling the get mappings response
we should move the serialization to the management pool.
The trade-off of introducing one or two new context switches for responses that are
small enough to not cause trouble on the transport thread to prevent instability
in case of a large number of mappings in the cluster seems worth it.
It is not realistic to drop messages without eventually failing.
To retain the coverage of long pauses this PR adjusts the blackholed
behavior to fail a send after 24h (which is assumed to be longer than any
timeout in the system) instead of never.
Closes#61034
Before when a value was copied to a field through a parent field or `copy_to`,
we parsed it using the `FieldMapper` from the source field. Instead we should
parse it using the target `FieldMapper`. This ensures that we apply the
appropriate mapping type and options to the copied value.
To implement the fix cleanly, this PR refactors the value parsing strategy. Now
instead of looking up values directly, field mappers produce a helper object
`ValueFetcher`. The value fetchers are responsible for almost all aspects of
fetching, including looking up the right paths in the _source.
The PR is fairly big but each commit can be reviewed individually.
Fixes#61033.
Previously we didn't retain the requested fields when performing a shallow copy
of the search source. This meant that when a search was rewritten, we could drop
the requested fields and fail to return them in the response.
Saving some cycles here and there on the IO loop:
* Don't instantiate new `Runnable` to execute on `SAME` in a few spots
* Don't instantiate complicated wrapped stream for empty messages
* Stop instantiating almost never used `ClusterStateObserver` in two spots
* Some minor cleanup and preventing pointless `Predicate<>` instantiation in transport master node action
In addition, this commit converts ScaledFloatFieldMapper as it was relying
on a number of static values taken from NumberFieldMapper that had changed
or been removed.
Previously migration guide incorrectly stated that joda-time patterns have to be fixed before upgrading to 7.x
since (7.7) #52555 and our bwc policy 6.x created indices even with joda-time are supported

This switches a few tests for field mappers from `ESSingleNodeTestCase`
to `ESTestCase` because, in general, we prefer to avoid
`ESSingleNodeTestCase` when we can because it is slow and "big". "Big"
here means that it pulls in an entire node, making it difficult to
reason about what you are testing.
The test didn't take into account the case where 0 documents are
indexed into the shard, meaning that files aren't loaded during
the pre-warm phase. The test injects FileSystem failures, if
the snapshot doesn't contain any files, pre-warm doesn't read
any files and the recovery completes normally.
Closes#61295
Backport of #61317
We have to set the recovery setting to `0` if we don't want throttling
from recoveries. Otherwise the randomized value used for this setting in
tests can lead to throttling unexpectedly.
Closes#61311
With #60683 we stopped forcing aggregating all docs using a single
Aggregator which made some of our accuracy assumptions about the stats
aggregator incorrect. This adds a test that does the forcing and asserts
the old accuracy and adds a test without the forcing with much looser
accuracy guarantees.
Closes#61132
The FieldNamesFieldMapper field has different behaviour for indexes created in
clusters earlier than v6.1, and the code to deal with this was still using the vestigial
FieldType field of FieldMapper in its indexing path. This meant that documents
added after an upgrade were not correctly indexing their field names field. This
commit corrects the parseCreateField method to use the default field type.
Fixes#61305
Today a common reason for a `ShardLockObtainFailedException` is when a
shard is removed from a node and then assigned straight back to it again
before the node has had a chance to shut the previous shard instance
down. For instance, this can happen if a node briefly leaves the cluster
holding a primary with no in-sync replicas.
The message in this case is typically as follows:
obtaining shard lock timed out after 5000ms, previous lock details: [shard creation] trying to lock for [shard creation]
This is pretty hard to interpret, and doesn't raise the important
question: "why didn't the shard shut down sooner?"
With this change we reword the message a bit, report the age of the
shard lock, and adjust the details to report that the lock is held by a
closing shard:
obtaining shard lock for [starting shard] timed out after [5000ms], lock already held for [closing shard] with age [12345ms]
Relates #38807
`ESTestCase#testRandomDateFormatterPattern` previously asserted that
round tripping `millis -> text -> millis` wouldn't lose any precision.
But some date formats don't include the time of day so, of course, this
could lose precision. This replaces that with an assertion that
`text -> millis -> text` doesn't lose precision. Which should be true
for any sane date format. Really, we're just trying to make sure that
the random date formats that we return are *fairly* sane.
We have seen a situation where the total search operations are higher
than expected. Unfortunately, we did not have enough info to figure it
out. This commit adds the failures to the error to provide more context
and adjusts the log level in case of failure to debug.
