This commit modifies the put follow index action to use a
CcrRepository when creating a follower index. It routes
the logic through the snapshot/restore process. A
wait_for_active_shards parameter can be used to configure
how long to wait before returning the response.
This change adds a _meta field storing the version in which
the index mappings were last updated to the 3 ML indices
that didn't previously have one:
- .ml-annotations
- .ml-meta
- .ml-notifications
All other ML indices already had such a _meta field.
This field will be useful if we ever need to automatically
update the index mappings during a future upgrade.
Runnables can be submitted to
AutodetectProcessManager.AutodetectWorkerExecutorService
without error after it has been shutdown which can lead
to requests timing out as their handlers are never called
by the terminated executor.
This change throws an EsRejectedExecutionException if a
runnable is submitted after after the shutdown and calls
AbstractRunnable.onRejection on any tasks not run.
Closes#37108
This commit changes the TransportVerifyShardBeforeCloseAction so that it issues a
forced flush, forcing the translog and the Lucene commit to contain the same max seq
number and global checkpoint in the case the Translog contains operations that were
not written in the IndexWriter (like a Delete that touches a non existing doc). This way
the assertion added in #37426 won't trip.

This commit moves the auditing of job deletion related errors
to the final listener in the job delete action. This ensures
any error that occurs during job deletion is audited.
In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine.
To populate additional fields node.id and cluster.uuid which are not available at start time,
a cluster state update will have to be received and the values passed to log4j pattern converter.
A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter.
Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace
see ESJsonLayout.java for more details and field descriptions
Docker log4j2 configuration is now almost the same as the one use for ES binary.
The only difference is that docker is using console appenders, whereas ES is using file appenders.

This commit allows JIRA API fields that require a list of key/value
pairs (maps), such as JIRA "components" to use use template snippets
(e.g. {{ctx.payload.foo}}). Prior to this change the templated value
(not the de-referenced value) would be sent via the API and error.
Closes#30068
We inject an Unfollow action before Shrink because the Shrink action
cannot be safely used on a following index, as it may not be fully
caught up with the leader index before the "original" following index is
deleted and replaced with a non-following Shrunken index. The Unfollow
action will verify that 1) the index is marked as "complete", and 2) all
operations up to this point have been replicated from the leader to the
follower before explicitly disconnecting the follower from the leader.
Injecting an Unfollow action before the Rollover action is done mainly
as a convenience: This allow users to use the same lifecycle policy on
both the leader and follower cluster without having to explictly modify
the policy to unfollow the index, while doing what we expect users to
want in most cases.
If the index request is executed before the mapping update is applied on
the IndexShard, the index request will perform a dynamic mapping update.
This mapping update will be timeout (i.e, ProcessClusterEventTimeoutException)
because the latch is not open. This leads to the failure of the index
request and the test. This commit makes sure the mapping is ready
before we execute the index request.
Closes#37807
This commit adds deprecation warnings for index actions

* ML: Add MlMetadata.upgrade_mode and API

* adjusting doc tests
* adding upgrade mode tests to black list
We have read and write aliases for the ML results indices. However,
the job still had methods that purported to reliably return the name
of the concrete results index being used by the job. After reindexing
prior to upgrade to 7.x this will be wrong, so the method has been
renamed and the comments made more explicit to say the returned index
name may not be the actual concrete index name for the lifetime of the
job. Additionally, the selection of indices when deleting the job
has been changed so that it works regardless of concrete index names.
All these changes are nice-to-have for 6.7 and 7.0, but will become
critical if we add rolling results indices in the 7.x release stream
as 6.7 and 7.0 nodes may have to operate in a mixed version cluster
that includes a version that can roll results indices.
* Changed `LuceneSnapshot` to throw an `OperationsMissingException` if the requested ops are missing.
* Changed the shard changes api to handle the `OperationsMissingException` and wrap the exception into `ResourceNotFound` exception and include metadata to indicate the requested range can no longer be retrieved.
* Changed `ShardFollowNodeTask` to handle this `ResourceNotFound` exception with the included metdata header.

This commit introduces the `create_snapshot` cluster privilege and
the `snapshot_user` role.
This role is to be used by "cronable" tools that call the snapshot API
periodically without recurring to the `manage` cluster privilege. The
`create_snapshot` cluster privilege is much more limited compared to
the `manage` privilege.
The `snapshot_user` role grants the privileges to view the metadata of
all indices (including restricted ones, i.e. .security). It obviously grants the
create snapshot privilege but the repository has to be created using another
role. In addition, it grants the privileges to (only) GET repositories and
snapshots, but not create and delete them.
The role does not allow to create repositories. This distinction is important
because snapshotting equates to the `read` index privilege if the user has
control of the snapshot destination, but this is not the case in this instance,
because the role does not grant control over repository configuration.
This commit introduces retention lease syncing from the primary to its
replicas when a new retention lease is added. A follow-up commit will
add a background sync of the retention leases as well so that renewed
retention leases are synced to replicas.
Made the test tolerant to index upgrade being run
in between the old/mixed/upgraded portions. This
can occur because the rolling upgrade tests all
share the same indices.
Fixes#37763
The ML file structure finder has always reported both Joda
and Java time format strings. This change makes the Java time
format strings the ones that are incorporated into mappings
and ingest pipeline definitions.
The BWC syntax of prepending "8" to these formats is used.
This will need to be removed once Java time format strings
become the default in Elasticsearch.
This commit also removes direct imports of Joda classes in the
structure finder unit tests. Instead the core Joda BWC class
is used.
* Exit batch files explictly using ERRORLEVEL
This makes sure the exit code is preserved when calling the batch
files from different contexts other than DOS
Fixes#29582
This also fixes specific error codes being masked by an explict
exit /b 1
causing the useful exitcodes from ExitCodes to be lost.

The TransportUnfollowAction updates the index settings but does not
increase the settings version to reflect that change.
This issue has been caught while working on the replication of closed
indices (#33888). The IndexFollowingIT.testUnfollowIndex() started to
fail and this specific assertion tripped. It does not happen on master
branch today because index metadata for closed indices are never
updated in IndexService instances, but this is something that is going
to change with the replication of closed indices.
The unlucky timing can cause this test to fail when the indexing is triggered from `maybeTriggerAsyncJob`. As this is asynchronous, in can finish quicker then the test stepping over to next assertion
The introduced barrier solves the problem
closes#37695
* Remove empty statements
There are a couple of instances of undocumented empty statements all across the
code base. While they are mostly harmless, they make the code hard to read and
are potentially error-prone. Removing most of these instances and marking blocks
that look empty by intention as such.
* Change test, slightly more verbose but less confusing
When upgrading from 5.4 to 5.5 to 6.7 (inclusive) it was
necessary to ensure there was a mapping for type "doc" on
the ML state index before opening a job. This was because
5.4 created a multi-type ML state index.
In version 7.x we can be sure that any such 5.4 index is no
longer in use. It would have had to be reindexed into the
6.x index format prior to the upgrade to version 7.x.
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.
Closes#33028
When an index is frozen, two index settings are updated (index.frozen and
index.search.throttled) but the settings version is left unchanged and does
not reflect the settings update. This commit change the
TransportFreezeIndexAction so that it also increases the settings version
when an index is frozen/unfrozen.
This issue has been caught while working on the replication of closed
indices (#3388) in which index metadata for a closed index are updated
to frozen metadata and this specific assertion tripped.
The default value for ssl.supported_protocols no longer includes TLSv1
as this is an old protocol with known security issues.
Administrators can enable TLSv1.0 support by configuring the
appropriate `ssl.supported_protocols` setting, for example:
xpack.security.http.ssl.supported_protocols: ["TLSv1.2","TLSv1.1","TLSv1"]

This deprecates the `xpack.watcher.history.cleaner_service.enabled` setting,
since all newly created `.watch-history` indices in 7.0 will use ILM to manage
their retention.
In 8.0 the setting itself and cleanup actions will be removed.
Resolves#32041
Today, the mapping on the follower is managed and replicated from its
leader index by the ShardFollowTask. Thus, we should prevent users

When the arguements of PERCENTILE and PERCENTILE_RANK can be folded,
the `ConstantFolding` rule kicks in and calls the `replaceChildren()`
method on `InnerAggregate` which is created from the aggregation rules
of the `Optimizerz. `InnerAggregate` in turn, cannot implement the method
as the logic of creating a new `InnerAggregate` instance from a list of
`Expression`s resides in the Optimizer. So, instead, `ConstantFolding`
should be applied before any of the aggregations related rules.

This change adds a docker compose configuration that's used with
the `elasticsearch.test.fixtures` plugin to start up the image
and check that the TCP ports are up.
We can build on this to add other checks for culster health,
run REST tests, etc.
We can add multiple containers and configurations to the compose
file (e.x. test different env vars) and form clusters.
When we can't map the principal attribute from the configured SAML
attribute in the realm settings, we can't complete the
authentication. We return an error to the user indicating this and
we present them with a list of attributes we did get from the SAML
response to point out that the expected one was not part of that
list. This list will never contain the NameIDs though as they are
not part of the SAMLAttribute list. So we might have a NameID but
just with a different format.
This commit removes the Index Audit Output type, following its deprecation
in 6.7 by 8765a31d4e6770. It also adds the migration notice (settings notice).
In general, the problem with the index audit output is that event indexing
can be slower than the rate with which audit events are generated,
especially during the daily rollovers or the rolling cluster upgrades.
In this situation audit events will be lost which is a terrible failure situation
for an audit system.
Besides of the settings under the `xpack.security.audit.index` namespace, the
`xpack.security.audit.outputs` setting has also been deprecated and will be
removed in 7. Although explicitly configuring the logfile output does not touch
any deprecation bits, this setting is made redundant in 7 so this PR deprecates
it as well.
