Refactors NodePersistentTask and RunningPersistentTask into a single AllocatedPersistentTask. Makes it possible to update Persistent Task Status via AllocatedPersistentTask.
If a persistent task throws an exception, the persistent tasks framework will no longer try to restart the task. This is a temporary measure to prevent threshing the cluster with endless restart attempt. We will revisit this in the future version to make the restart process more robust. Please note, however, that if node executing the task goes down, the task will still be restarted on another node.
Removes the transport layer dependency from PersistentActions, makes PersistentActionRegistry immutable and rename actions into tasks in class and variable names.
Refactors xcontent serialization of Request and Status to use their writable names instead of action name. That simplifies the parsing logic, allows reuse of the same status object for multiple actions and is consistent with how named objects in xcontent are used.
This will allow persistent task implementors to detect whether the executor node has changed or has been unset since the last status update has occured.
This commit moves persistent tasks from ClusterState.Custom to MetaData.Custom and adds ability for the task to remain in the metadata after completion.
Also replaced the DELETING status from JobState with a boolean flag on Job. The state of a job is now stored inside a persistent task in cluster state. Jobs that aren't running don't have a persistent task, so I moved that notion of being deleted to the job config itself.

Similarly to task status on normal tasks it's now possible to update task status on the persistent tasks. This should allow updating the state of the running tasks (such as loading, started, etc) as well as store intermediate state or progress.
Original commit: elastic/x-pack@048006b467
A persistent action is a transport-like action that is using the cluster state instead of transport to start tasks. This allows persistent tasks to survive restart of executing nodes. A persistent action can be implemented by extending TransportPersistentAction. TransportPersistentAction will start the task by using PersistentActionService, which controls persistent tasks lifecycle. See TestPersistentActionPlugin for an example implementing a persistent action.

This change switches the merge policy to none (for this specific test) in order to make sure that refreshes are always triggered
by a change in the writer.
Closes#27514
Factors the way in which XContent parsing handles deprecated fields
into a callback that is set at parser construction time. The goals here
are:
1. Remove Log4J as a dependency of XContent so that XContent can be used
by clients without forcing log4j and our particular deprecation handling
scheme.
2. Simplify handling of deprecated fields in tests. Now tests can listen
directly for the deprecation callback rather than digging through a
ThreadLocal.
More accurately, this change begins this work. It deprecates a number of
methods, pointing folks to the new versions of those methods that take
`DeprecationHandler`. The plan is to slowly drop these deprecated
methods. Once they are entirely removed we can remove Log4j as
dependency of XContent.
This change adds support for the new ranking evaluation API to the High Level Rest Client.
This mostly means adding support for parsing the various response objects back from the
REST representation. It includes one change to the response syntax where previously we didn't
print the type of the metric details section but we now need it to pick the right parser to
parse this section back.
Closes#28198
Script fields can get a bit more complicated than just stored fields. A script can return null, an object and also an array. Extended parsing to support such valid values. Also renamed util method from `parseStoredFieldsValue` to `parseFieldsValue` given that it can parse stored fields but also script fields, anything that's returned as `fields`.
Closes#28380
The test currently makes the assumption that if underlying directory stops throwing exceptions, we can always open the engine. This is not the case as some errors can cause a corruption marker to be placed in the store.
This commit refactors the test to only check that everything is OK if the engine was successfully opened. On top of that, there is no point in checking replay with no errors as we have another test for that.
Closes#28426
This adds the ability to index term prefixes into a hidden subfield, enabling prefix queries to be run without multitermquery rewrites. The subfield reuses the analysis chain of its parent text field, appending an EdgeNGramTokenFilter. It can be configured with minimum and maximum ngram lengths. Query terms with lengths outside this min-max range fall back to using prefix queries against the parent text field.
The mapping looks like this:
"my_text_field" : {
"type" : "text",
"analyzer" : "english",
"index_prefix" : { "min_chars" : 1, "max_chars" : 10 }
}

This commit switches the internal format of the elasticsearch keystore
to no longer use java's KeyStore class, but instead encrypt the binary
data of the secrets using AES-GCM. The cipher key is generated using
PBKDF2WithHmacSHA512. Tests are also added for backcompat reading the v1
and v2 formats.
Currently meta plugins will ask for confirmation of security policy
exceptions for each bundled plugin. This commit collects the necessary
permissions of each bundled plugin, and asks for confirmation of all of
them at the same time.
In some cases testShrinkIndexPrimaryTerm creates then 'mutates' 210
shards. If each shard opens more than 10 files (translog, lucene index),
we exceeded the maximum allowed file handles. In our test, the number of
file handles is limited to 2048 by HandleLimitFS. This commit reduces
the number of shards in testShrinkIndexPrimaryTerm to avoid such errors.
Closes#28153
In rare cases the total nanoseconds for an entire window of operations can be 0
nanoseconds, causing the assertion in
QueueResizingEsThreadPoolExecutor.calculateLambda to trip. This ensures that we
calculate the lambda value with at least 1 nanosecond.
Resolves#27607
Currently this method parses the string as a double. This means that it
might lose accuracy if the value is a long that is greater than
2^52. This commit changes this method to try to detect whether the
string represents a long first.
Today after writing an operation to an engine, we will call
`IndexShard#afterWriteOperation` to flush a new commit if needed. The
`shouldFlush` condition is purely based on the uncommitted translog size
and the translog flush threshold size setting. However this can cause a
replica execute an infinite loop of flushing in the following situation.
1. Primary has a fully baked index commit with its local checkpoint
equals to max_seqno
2. Primary sends that fully baked commit, then replays all retained
translog operations to the replica
3. No operations are added to Lucence on the replica as seqno of these
operations are at most the local checkpoint
4. Once translog operations are replayed, the target calls
`IndexShard#afterWriteOperation` to flush. If the total size of the
replaying operations exceeds the flush threshold size, this call will
`Engine#flush`. However the engine won't flush as its index writer does
not have any uncommitted operations. The method
`IndexShard#afterWriteOperation` will keep flushing as the condition
`shouldFlush` is still true.
This issue can be avoided if we always flush if the `shouldFlush`
condition is true.
This PR removes previously deprecated `isShardsAcked()` method in
favour of `isShardsAcknowledged()` on `CreateIndexResponse`, `CreateIndexClusterStateUpdateResponse` and `RolloverResponse`

This change adds the `after_key` of a composite aggregation directly in the response.
It is redundant when all buckets are not filtered/removed by a pipeline aggregation since in this case the `after_key` is always the last bucket
in the response. Though when using a pipeline aggregation to filter composite buckets, the `after_key` can be lost if the last bucket is filtered.
This commit fixes this situation by always returning the `after_key` in a dedicated section.
The DiscoveryNodes.Delta was changed in #28197. Previous/Master nodes
are now always set in the `Delta` (before the change they were set only
if the master changed) and the `masterChanged()` method is now based on
object equality and nodes ephemeral ids (before the change it was based
on nodes id).
This commit adapts the DiscoveryNodesTests.testDeltas() to reflect the
changes.
We introduced a single commit assertion when opening an index but create
a new translog. However, this assertion is not held in this situation.
1. A replica with two commits c1 and c2 starts peer-recovery with c1
2. The recovery is sequence-based recovery but the primary is before 6.2 so
it sent true for “createNewTranslog”
3. Replica opens engine and create translog. We expect "open index and
create translog" have 1 commit but we have c1 and c2.
This commit makes sure to assert this iff the index was created on 6.2+.
This introduces a settings updater that allows to specify a list of
settings. Whenever one of those settings changes, the whole block of
settings is passed to the consumer.
This also fixes an issue with affix settings, when used in combination
with group settings, which could result in no found settings when used
to get a setting for a namespace.
Lastly logging has been slightly changed, so that filtered settings now
only log the setting key.
Another bug has been fixed for the mock log appender, which did not
work, when checking for the exact message.
Closes#28047
Self referencing maps can cause SOE if they are iterated ie. in their toString methods. This chance adds some protected to the usage of those collections.
This commit adds the ability to specify a date format on the `date_histogram` composite source.
If the format is defined, the key for the source is returned as a formatted date.
Closes#27923
The tests for those field types were removed in #26549 because the range mapper
was moved to a module, but later this mapper was moved back to core in #27854.
This change adds back those two field types like before to the general setup in
AbstractQueryTestCase and adds some specifics to the RangeQueryBuilder and
TermsQueryBuilder tests. Also adding back an integration test in SearchQueryIT that
has been removed before but that can be kept with the mapper back in core now.
