Currently in the transport-nio work we connect and bind channels on the
a thread before the channel is registered with a selector. Additionally,
it is at this point that we set all the socket options. This commit
moves these operations onto the event-loop after the channel has been
registered with a selector. It attempts to set the socket options for a
non-server channel at registration time. If that fails, it will attempt
to set the options after the channel is connected. This should fix
#41071.
In the FIPS JVM the JVM default locale seems to leak into places
where it should be overridden. This change skips assertions
in TimestampFormatFinderTests.testGuessIsDayFirstFromLocale
that may be impacted.
Fixes#45140
Today we recover a replica by copying operations from the primary's translog.
However we also retain some historical operations in the index itself, as long
as soft-deletes are enabled. This commit adjusts peer recovery to use the
operations in the index for recovery rather than those in the translog, and
ensures that the replication group retains enough history for use in peer
recovery by means of retention leases.

Reloading of synonym_graph filter doesn't work currently because the search time
AnalysisMode doesn't get propagated to the TokenFilterFactory emitted by the
graph filters getChainAwareTokenFilterFactory() method. This change fixes that.

When doing a fieldwise Levenshtein distance comparison
between CSV rows, this change ignores all fields that
have long values, not just the longest field.
This approach works better for CSV formats that have
multiple freeform text fields rather than just a single
"message" field.
Fixes#45047
This change improves the exception messages that are thrown when the
system cannot read TLS resources such as keystores, truststores,
certificates, keys or certificate-chains (CAs).
This change specifically handles:
- Files that do not exist
- Files that cannot be read due to file-system permissions
- Files that cannot be read due to the ES security-manager

There are no realms that can be configured exclusively with secure
settings. Every realm that supports secure settings also requires one
or more non-secure settings.
However, sometimes a node will be configured with entries in the
keystore for which there is nothing in elasticsearch.yml - this may be
because the realm we removed from the yml, but not deleted from the
keystore, or it could be because there was a typo in the realm name
which has accidentially orphaned the keystore entry.
In these cases the realm building would fail, but the error would not
always be clear or point to the root cause (orphaned keystore
entries). RealmSettings would act as though the realm existed, but
then fail because an incorrect combination of settings was provided.
This change causes realm building to fail early, with an explicit
message about incorrect keystore entries.

When we create API key we check if the API key with the name
already exists. It searches with scroll enabled and this causes
the request to fail when creating large number of API keys in
parallel as it hits the number of open scroll limit (default 500).
We do not need the search context to be created so this commit
removes the scroll parameter from the search request for duplicate
API key.
If one tries to start a DF analytics job that has already run,
the result will be that the task will fail after reindexing the
dest index from the source index. The results of the prior run
will be gone and the task state is not properly set to failed
with the failure reason.
This commit improves the behavior in this scenario. First, we
set the task state to `failed` in a set of failures that were
missed. Second, a validation is added that if the destination
index exists, it must be empty.
We keep adding the current primary term to operations for which we do not assign a sequence
number. This does not make sense anymore as all operations which we care about have
sequence numbers now. The goal of this commit is to clean things up in InternalEngine and
reduce the complexity.
* We shouldn't be recreating wrapped REST handlers over and over for every request. We only use this hook in x-pack and the wrapper there does not have any per request state.
This is inefficient and could lead to some very unexpected memory behavior
=> I made the logic create the wrapper on handler registration and adjusted the x-pack wrapper implementation to correctly forward the circuit breaker and content stream flags
The Get Users API also returns users form the restricted realm or built-in users,
as we call them in our docs. One can also change the passwords of built-in
users with the Change Password API
A mismatched configuration between the IdP and SP will often result in
SAML authentication attempts failing because the audience condition is
not met (because the IdP and SP disagree about the correct form of the
SP's Entity ID).
Previously the error message in this case did not provide sufficient
information to resolve the issue because the IdP's expected audience
would be truncated if it exceeeded 32 characters. Since the error did
not provide both IDs in full, it was not possible to determine the
correct fix (in detail) based on the error alone.
This change expands the message that is included in the thrown
exception, and also adds additional logging of every failed audience
condition, with diagnostics of the match failure.

Today closing a `ClusterNode` in an `AbstractCoordinatorTestCase` uses
`onNode()` so has no effect if the node is not in the current list of nodes.
It also discards the `Runnable` it creates without having run it, so has no
effect anyway.
This commit makes these tests much stricter about properly closing the nodes
started during `Coordinator` tests, by tracking the persisted states that are
opened, and adds an assertion to catch the trappy requirement that the closing
node still belongs to the cluster.
The existing equals check was broken, and would always be false.
The correct behaviour is to return "Collections.emptyList()" whenever
the the active(licensed)-realms equals the configured-realms.

* Rename indexlifecycle to ilm and snapshotlifecycle to slm (#44917)
As a followup to #44725 and #44608, which renamed the packages within
the x-pack project, this renames the packages within the core x-pack
project. It also renames 'snapshotlifecycle' within the HLRC to slm.
* Fix one more import
In case closing the process throws an exception we should be catching
it no matter its type. The process may have terminated because of a
fatal error in which case closing the process will throw a server
error, not an `IOException`. If this happens we fail to mark the
persistent task as failed and the task gets in limbo.
As data frame rows with missing values for analyzed fields are skipped,
we can be more efficient by including a query that only picks documents
that have values for all analyzed fields. Besides improving the number
of documents we go through, we also provide a more accurate measurement
of how many rows we need which reduces the memory requirements.
This also adds an integration test that runs outlier detection on data
with missing fields.
TaskListener accepts today Throwable in its onFailure method. Though
looking at where it is called (TransportAction), it can never be
notified of a Throwable.
This commit changes the signature of TaskListener#onFailure so that it
accepts an `Exception` rather than a `Throwable` as second argument.
In order to make it easier to interpret the output of the ILM Explain
API, this commit adds two request parameters to that API:
- `only_managed`, which causes the response to only contain indices
which have `index.lifecycle.name` set
- `only_errors`, which causes the response to contain only indices in an
ILM error state
"Error state" is defined as either being in the `ERROR` step or having
`index.lifecycle.name` set to a policy that does not exist.
Today the processors setting is permitted to be set to more than the
number of processors available to the JVM. The processors setting
directly sizes the number of threads in the various thread pools, with
most of these sizes being a linear function in the number of
processors. It doesn't make any sense to set processors very high as the
overhead from context switching amongst all the threads will overwhelm,
and changing the setting does not control how many physical CPU
resources there are on which to schedule the additional threads. We have
to draw a line somewhere and this commit deprecates setting processors
to more than the number of available processors. This is the right place
to draw the line given the linear growth as a function of processors in
most of the thread pools, and that some are capped at the number of
available processors already.
Since 7.3, it's possible to explicitly configure the SAML realm to
be used in Kibana's configuration. This in turn, eliminates the need
of properly setting `xpack.security.public.*` settings in Kibana
and largely simplifies relevant documentation.
This also changes `xpack.security.authProviders` to
`xpack.security.authc.providers` as the former was deprecated in
favor of the latter in 7.3 in Kibana
This is a followup to #44350. The indexer stats used to
be persisted standalone, but now are only persisted as
part of a state-and-stats document. During the review
of #44350 it was decided that we'll stick with this
design, so there will never be a need for an indexer
stats object to store its transform ID as it is stored
on the enclosing document. This PR removes the indexer
stats document ID.
Backport of #44768
The problem is that RemoteClusterConnection closes the connection manager asynchronously, which races with the threadpool being shutdown at the end of the test.
Closes#44339Closes#44610
Deleting a follower index does not delete its ShardFollowTasks, potentially
leaving many persistent tasks in the cluster that cannot be allocated on
nodes and unnecessary fill the logs. This commit adds a cluster state listener
(ShardFollowTaskCleaner) that completes (with a failure) any persistent task
that refers to a non existent follower index.
I think that this bug has been introduced by #34404: before this change the
task would have been completed as failed and removed from the cluster state.
Backport of #44702 and #44801 on 7.x
* Switch from using docvalue_fields to extracting values from _source
where applicable. Doing this means parsing the _source and handling the
numbers parsing just like Elasticsearch is doing it when it's indexing
a document.
* This also introduces a minor limitation: aliases type of fields that
are NOT part of a tree of sub-fields will not be able to be retrieved
anymore. field_caps API doesn't shed any light into a field being an
alias or not and at _source parsing time there is no way to know if a
root field is an alias or not. Fields of the type "a.b.c.alias" can be
extracted from docvalue_fields, only if the field they point to can be
extracted from docvalue_fields. Also, not all fields in a hierarchy of
fields can be evaluated to being an alias.
