For #58994 it would be useful to be able to share test infrastructure.
This PR shares `AbstractSnapshotIntegTestCase` for that purpose, dries up SLM tests
accordingly and adds a shared and efficient (compared to the previous implementations)
way of waiting for no running snapshot operations to the test infrastructure to dry things up further.
There have been a few test failures that are likely caused by tests
performing actions that use ML indices immediately after the actions
that create those ML indices. Currently this can result in attempts
to search the newly created index before its shards have initialized.
This change makes the method that creates the internal ML indices
that have been affected by this problem (state and stats) wait for
the shards to be initialized before returning.

* Fix external javadoc reference to server project
This fixes https://github.com/elastic/infra/issues/20103
The problem here is that we rename all artifacts in the :server project to
elasticsearch. The ideal fix would be to rename the gradle project there
to elasticsearch. I'm open to that but it seems quite invasive. Would love to hear
other opinions on that.
The applied alternative minimal invasive fix provided with this PR just takes
potential renamed projects / artifacts (Currently I only see `:server`) into account
when declaring external links.
* Simplify javadoc link base name
* Enforce higher priority for RepositoriesService ClusterStateApplier
This avoids shards allocation failures when the repository instance
comes in the same ClusterState update as the shard allocation.

This commit creates a new Gradle plugin to provide a separate task name
and source set for running YAML based REST tests. The only project
converted to use the new plugin in this PR is distribution/archives/integ-test-zip.
For which the testing has been moved to :rest-api-spec since it makes the most
sense and it avoids a small but awkward change to the distribution plugin.
The remaining cases in modules, plugins, and x-pack will be handled in followups.
This plugin is distinctly different from the plugin introduced in #55896 since
the YAML REST tests are intended to be black box tests over HTTP. As such they
should not (by default) have access to the classpath for that which they are testing.
The YAML based REST tests will be moved to separate source sets (yamlRestTest).
The which source is the target for the test resources is dependent on if this
new plugin is applied. If it is not applied, it will default to the test source
set.
Further, this introduces a breaking change for plugin developers that
use the YAML testing framework. They will now need to either use the new source set
and matching task, or configure the rest resources to use the old "test" source set that
matches the old integTest task. (The former should be preferred).
As part of this change (which is also breaking for plugin developers) the
rest resources plugin has been removed from the build plugin and now requires
either explicit application or application via the new YAML REST test plugin.
Plugin developers should be able to fix the breaking changes to the YAML tests
by adding apply plugin: 'elasticsearch.yaml-rest-test' and moving the YAML tests
under a yamlRestTest folder (instead of test)
This allows pipeline aggregations to participate in the up-front rewrite
phase for searches, in particular, it allows them to load data that they
need asynchronously.

The current internal sequence algorithm relies on fetching multiple results and then paginating through the dataset. Depending on the dataset and memory, setting a larger page size can yield better performance at the expense of memory.
This PR makes this behavior explicit by decoupling the fetch size from size, the maximum number of results desired.
As such, use in testing a minimum fetch size which exposed a number of bugs:
Jumping across data across queries causing valid data to be seen as a gap.
Incorrectly resuming searching across pages (again causing data to be discarded).
which have been addressed.

The PR introduces following two changes:
Move API key validation into a new separate threadpool. The new threadpool is created separately with half of the available processors and 1000 in queue size. We could combine it with the existing TokenService's threadpool. Technically it is straightforward, but I am not sure whether it could be a rushed optimization since I am not clear about potential impact on the token service.
On threadpoool saturation, it now fails with EsRejectedExecutionException which in turns gives back a 429, instead of 401 status code to users.
Backport of #58582 to 7.x branch.
This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.
The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

Dry up tests that use a disruption that isolates the master from all other nodes.
Also, turn disruption types that have neither parameters nor state into constants
to make things a little clearer.
This commit changes our behavior in 2 ways:
- When mapping claims to user properties ( principal, email, groups,
name), we only handle string and array of string type. Previously
we would fail to recognize an array of other types and that would
cause failures when trying to cast to String.
- When adding unmapped claims to the user metadata, we only handle
string, number, boolean and arrays of these. Previously, we would
fail to recognize an array of other types and that would cause
failures when attempting to process role mappings.
For user properties that are inherently single valued, like
principal(username) we continue to support arrays of strings where
we select the first one in case this is being depended on by users
but we plan on removing this leniency in the next major release.

Despite all my attempts I did not manage to reproduce issues like the ones
described in #58961. My guess is that the _mount request got retried at
some point but I wasn't able to validate this assumption.
Still, the FsSearchableSnapshotsIT can be pretty disk heavy if a small
random chunk size and a large number of documents is picked up in the
tests. The parent class also does not verify the acknowledged status
of some requests.
This commit lowers down the chunk size and number of docs in tests
(this is extensively tests in unit tests) and also adds assertions on
acknowledged responses.

Working through a heap dump for an unrelated issue I found that we can easily rack up
tens of MBs of duplicate empty instances in some cases.
I moved to a static constructor to guard against that in all cases.
Since 2.0.0 (56a264cf6d) we have documented that restoring a snapshot
typically results in `red` cluster health. However since 5.0.0 (#19516)
this hasn't been true, we report `yellow` health for unassigned
primaries that will be recovered from a snapshot in the future. This
commit adjusts these docs to match today's behaviour.
* SQL: Redact credentials in connection exceptions (#58650)
This commit adds the functionality to redact the credentials from the
exceptions generated when a connection attempt fails, preventing them
from leaking into logs, console history etc.
There are a few causes that can lead to failed connections. The most
challenging to deal with is a malformed connection string. The redaction
tries to get around it by modifying the URI to a parsable state, so that
the redaction can be applied reliably. If there's no reliability
guarantee, the redaction will bluntly replace the entire connection
string and the user informed about the option to modify it so that the
redaction won't apply. (This is done by using a caplitalized scheme,
which is legal, but otherwise never used in practice.)
The commit fixes a couple of other issues with the URI parser:
- it allows an empty hostname, or even entire connection string (as per
the existing documentation);
- it reduces the editing of the connection string in the exception
messages (so that the user easier recognize their input);
- it uses the default URI as source for the scheme and hostname.

SQL: fix handling of escaped chars in JDBC connection string (#58429)
This commit fixes an issue emerging when the connection string URI
contains escaped characters.
The original URI is pre-parsed in order to re-assemble a new URI having
the optional elements filled in with defaults. The new URI has been
using however the unescaped query and fragment parts. So if these
contained any escaped `&` or `=` (such as in the password option value),
the unescaping would reveal them and make them later interfere with the
options parsing.
The commit changes that, so that the new URI be built from the unescaped
"raw" parts of the original URI.
(cherry picked from commit 94eb5a05e79c6e203de548d05b13e00295bd4489)
- The exception that we caught when failing to schedule a thread was incorrect.
- We may have failures when reducing the response before returning it, which were not handled correctly and may have caused get or submit async search task to not be properly unregistered from the task manager
- when the completion listener onFailure method is invoked, the search task has to be unregistered. Not doing so may cause the search task to be stuck in the task manager although it has completed.
Closes#58995
.ml-state-write is supposed to be an index alias, however by accident it can become an index. If
.ml-state-write is a concrete index instead of an alias ML stops working. This change improves error
handling by setting the job to failed and properly log and audit the problem. The user still has to
manually fix the problem. This change should lead to a quicker resolution of the problem.
fixes#58482
When we execute search against remote indices, the remote indices are authorized on the remote cluster and not on the CCS cluster. When we introduced submit async search we added a check that requires that the user running it has the privilege to execute it on some index. That prevents users from executing async searches against remote indices unless they also have read access on the CCS cluster, which is common when the CCS cluster holds no data.
The solution is to let the submit async search go through as we already do for get and delete async search. Note that the inner search action will still check that the user can access local indices, and remote indices on the remote cluster, like search always does.
