We added support for role mapper expression DSL in #33745,
that allows us to build the role mapper expression used in the
role mapping (as rules for determining user roles based on what
the boolean expression resolves to).
This change now adds support for create/update role mapping
API to the high-level rest client.
Today when submitting an update settings request to update the number of
replicas with a wildcard that does not match any indices and allow no
indices is set to true, the request ends up being interpreted as
updating the number of replicas for all indices. That is, consider the
following sequence:
PUT /test-index
{
"settings": {
"index.number_of_replicas": 0
}
}
PUT /non-existent-*/_settings?expand_wildcards=open&allow_no_indices=true
{
"settings": {
"index.number_of_replicas": 1
}
}
GET /test-index/_settings
The latter will show that the number of replicas on test-index is now
one. This is surprising, and should be considered a bug.
The underlying problem here is treating no indices in the underlying
methods used to update the routing table and the metadata as meaning all
indices. This commit takes away this assumption. Tests that relied on
this behavior have been changed to no longer rely on this.
A test for this situation is added in UpdateNumberOfReplicasIT.
This removes another two methods from `AbstractComponent`. One isn't
used at all and another is only used in a single class in watcher. I've
moved the method that watcher uses into the single class that uses it.
Security caches the result of role lookups and negative lookups are
cached indefinitely. In the case of transient failures this leads to a
bad experience as the roles could truly exist. The CompositeRolesStore
needs to know if a failure occurred in one of the roles stores in order
to make the appropriate decision as it relates to caching. In order to
provide this information to the CompositeRolesStore, the return type of
methods to retrieve roles has changed to a new class,
RoleRetrievalResult. This class provides the ability to pass back an
exception to the roles store. This exception does not mean that a
request should be failed but instead serves as a signal to the roles
store that missing roles should not be cached and neither should the
combined role if there are missing roles.
As part of this, the negative lookup cache was also changed from an
unbounded cache to a cache with a configurable limit.

This commit handles cases testing withLocale and withZone when the zone
and locale in question is the same as the special base case. This can
happen sometimes since the locale and zoneids are randomized.
Back in #32983 I broke running the integ-test-zip tests against an
external cluster by adding a test that reads the contents of the log
file. This fixes running against an external cluster by explicitly
skipping that test if running against an external cluster.
Empty values on keyword fields are filtered by the `map` execution mode
of the `terms` aggregation. This commit restores them as valid buckets.
Closes#34434
This commit removes randomization of locale for DateFormatter equals
tests, instead using explicit locales. The test framework already
randomizes locales, so the random choice of the second locale can
sometimes be equal to the already chosen locale. Randomization also does
not provide any extra protection, as the equality of DateFormatter does
not implement equality of the locales itself.
closes#34337
This commit removes the suggestions to send a PR with instructions for
more IDEs on disabling wildcard imports. This is not explicitly needed
both because the main IDEs instructions already exist, and any part of
the docs are welcome for PRs to add more clarity.

PR #34290 made it impossible to use thread-context values to pass
authentication metadata out of a realm. The SAML realm used this
technique to allow the SamlAuthenticateAction to process the parsed
SAML token, and apply them to the access token that was generated.
This new method adds metadata to the AuthenticationResult itself, and
then the authentication service makes this result available on the
thread context.
Closes: #34332
The ingest pipeline that is produced is very simple. It
contains a grok processor if the format is semi-structured
text, a date processor if the format contains a timestamp,
and a remove processor if required to remove the interim
timestamp field parsed out of semi-structured text.
Eventually the UI should offer the option to customize the
pipeline with additional processors to perform other data
preparation steps before ingesting data to an index.
In ccb9ab5717 we changed how we deal with time
fields to support the `DateTime`-format fields added in 6.0, but dropped
support for pre-6.x `Long`-format fields. This change reinstates this support
for cases where pre-6.x data is made available to ML (e.g. in a mixed-version
CCS setup or after an upgrade).
ListenableFuture may run a listener on the same thread that called the
addListener method or it may execute on another thread after the future
has completed. Whenever the ListenableFuture stores the listener for
execution later, it should preserve the thread context which is what
this change does.
Today we rewrite the operations from the leader with the term of the
following primary because the follower should own its history. The
problem is that a newly promoted primary may re-assign its term to
operations which were replicated to replicas before by the previous
primary. If this happens, some operations with the same seq_no may be
assigned different terms. This is not good for the future optimistic
locking using a combination of seqno and term.
This change ensures that the primary of a follower only processes an
operation if that operation was not processed before. The skipped
operations are guaranteed to be delivered to replicas via either
primary-replica resync or peer-recovery. However, the primary must not
acknowledge until the global checkpoint is at least the highest seqno of
all skipped ops (i.e., they all have been processed on every replica).

This removes the extraneous check to see if the class for a statically imported
method is already whitelisted, so a statically imported method can be whitelisted
independently.
Questions on how to work with `ActionPlugin#getRestHandlerWrapper()`
come up in discuss forums all the time. This change adds an example
to the javadoc how this method should/could be used.
* New OCTET_LENGTH function
* Changed the way the FunctionRegistry stores functions, considering the alphabetic ordering by name
* Added documentation for the RANDOM function
ES is scanning for dangling indices on every cluster state update. For this, it lists the subfolders of
the indices directory to determine which extra index directories exist on the node where there's no
corresponding index in the cluster state. These are potential targets for dangling index import. On
certain machine types, and with large number of indices, this subfolder listing can be horribly slow.
This means that every cluster state update will be slowed down by potentially hundreds of
milliseconds. One of the reasons for this poor performance is that Files.isDirectory() is a relatively
expensive call on some OS and JDK versions. There is no need though to do all these isDirectory
calls for folders which we know we are going to discard anyhow in the next step of the dangling
indices logic. This commit allows adding an exclusion predicate to the availableIndexFolders
methods which can dramatically speed up this method when scanning for dangling indices.
Since all calls to `ESLoggerFactory` outside of the logging package were
deprecated, it seemed like it'd simplify things to migrate all of the
deprecated calls and declare `ESLoggerFactory` to be package private.
This does that.
Also fixed ShardFollowNodeTaskTests to not return ops when responseSize
is empty. Otherwise ops are returned when no ops are expected to be returned.

Unfollow should be allowed / disallowed on a per index level instead of
cluster level.
Also renamed `create_follow_index` index privilege to
`manage_follow_index` privilege and include unfollow and close APIs.
