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.
Original commit: elastic/x-pack@21cd19ca1c
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.

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

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`

Adapt bwc version after backport #28310
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.

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

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.
Relates to #28147
* Notify affixMap settings when any under the registered prefix matches
Previously if an affixMap setting was registered, and then a completely
different setting was applied, the affixMap update consumer would be notified
with an empty map. This caused settings that were previously set to be unset in
local state in a consumer that assumed it would only be called when the affixMap
setting was changed.
This commit changes the behavior so if a prefix `foo.` is registered, any
setting under the prefix will have the update consumer notified if there are
changes starting with `foo.`.

In many cases we use the `ShardOperationFailedException` interface to abstract an exception that can only be of one type, namely `DefaultShardOperationException`. There is no need to use the interface in such cases, the concrete type should be used instead. That has the additional advantage of simplifying parsing such exceptions back from rest responses for the high-level REST client
If a get alias api call requests a specific alias pattern then
indices not having any matching aliases should not be included in the response.

This commit introduces the ability for the core Elasticsearch JAR to be
a multi-release JAR containing code that is compiled for JDK 8 and code
that is compiled for JDK 9. At runtime, a JDK 8 JVM will ignore the JDK
9 compiled classfiles, and a JDK 9 JVM will use the JDK 9 compiled
classfiles instead of the JDK 8 compiled classfiles. With this work, we
utilize the new JDK 9 API for obtaining the PID of the running JVM,
instead of relying on a hack.
For now, we want to keep IDEs on JDK 8 so when the build is in an IDE we
ignore the JDK 9 source set (as otherwise the IDE would give compilation
errors). However, with this change, running Gradle from the command-line
now requires JAVA_HOME and JAVA_9_HOME to be set. This will require
follow-up work in our CI infrastructure and our release builds to
accommodate this change.
Relates #28051
Keeping unsafe commits when opening an engine can be problematic because
these commits are not safe at the recovering time but they can suddenly
become safe in the future. The following issues can happen if unsafe
commits are kept oninit.
1. Replica can use unsafe commit in peer-recovery. This happens when a
replica with a safe commit c1 (max_seqno=1) and an unsafe commit c2
(max_seqno=2) recovers from a primary with c1(max_seqno=1). If a new
document (seqno=2) is added without flushing, the global checkpoint is
advanced to 2; and the replica recovers again, it will use the unsafe
commit c2 (max_seqno=2 <= gcp=2) as the starting commit for sequenced
based recovery even the commit c2 contains a stale operation and the
document (with seqno=2) will not be replicated to the replica.
2. Min translog gen for recovery can go backwards in peer-recovery. This
happens when a replica with a safe commit c1 (local_checkpoint=1,
recovery_translog_gen=1) and an unsafe commit c2 (local_checkpoint=2,
recovery_translog_gen=2). The replica recovers from a primary, and keeps
c2 as the last commit, then sets last_translog_gen to 2. Flushing a new
commit on the replica will cause exception as the new last commit c3
will have recovery_translog_gen=1. The recovery translog generation of a
commit is calculated based on the current local checkpoint. The local
checkpoint of c3 is 1 while the local checkpoint of c2 is 2.
3. Commit without translog can be used for recovery. An old index, which
was created before multiple-commits is introduced (v6.2), may not have a
safe commit. If that index has a snapshotted commit without translog and
an unsafe commit, the policy can consider the snapshotted commit as a
safe commit for recovery even the commit does not have translog.
These issues can be avoided if the combined deletion policy keeps only
the starting commit onInit.

The Java API documentation for index administration currenty is wrong because
the PutMappingRequestBuilder#setSource(Object... source) and
CreateIndexRequestBuilder#addMapping(String type, Object... source) methods
delegate to methods that check that the input arguments are valid key/value
pairs:
https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-admin-indices.html
This changes the docs so the java api code examples are included from
documentation integration tests so we detect compile and runtime issues earlier.

This method has a different contract than all the other methods in this class, returning null instead of an empty array when receiving a null input.

A bug introduced in #24407 currently prevents `eager_global_ordinals` from

mapping updates to not specify the `_parent` field if it doesn't need
updating, which was the goal of #24407.
The composite aggregation defers the collection of sub-aggregations to a second pass that visits documents only if they
appear in the top buckets. Though the scorer for sub-aggregations is not set on this second pass and generates an NPE if any sub-aggregation
tries to access the score. This change creates a scorer for the second pass and makes sure that sub-aggs can use it safely to check the score of
the collected documents.
The method `initiateChannel` on `TcpTransport` is explicit in that
channels can be connect asynchronously. All production implementations
do connect asynchronously. Only the blocking `MockTcpTransport`
connects in a synchronous manner. This avoids testing some of the
blocking code in `TcpTransport` that waits on connections to complete.
Additionally, it requires a more extensive method signature than
required for other transports.
This commit modifies the `MockTcpTransport` to make these connections
asynchronously on a different thread. Additionally, it simplifies that
`initiateChannel` method signature.
* Fix synonym phrase query expansion for cross_fields parsing
The `cross_fields` mode for query parser ignores phrase query generated by multi-word synonyms.
In such case only the first field of each analyzer group is kept. This change fixes this issue

This is related to #27933. It introduces a jar named elasticsearch-core

* Adds metadata to rewritten aggregations
Previous to this change, if any filters in the filters aggregation were rewritten, the rewritten version of the FiltersAggregationBuilder would not contain the metadata form the original. This is because `AbstractAggregationBuilder.getMetadata()` returns an empty map when not metadata is set.
Closes#28170
* Always set metadata when rewritten
As a replica always keeps a safe commit and starts peer-recovery with
that commit; file-based recovery only happens if new operations are
added to the primary and the required translog is not fully retained. In
the test, we tried to produce this condition by flushing a new commit in
order to trim all translog. However, if the new global checkpoint is not
persisted yet, we will keep two commits and not trim translog. This
commit tightens the file-based condition in the test by waiting for the
global checkpoint persisted properly on the new primary before flushing.

Today a replica starts a peer-recovery with the last commit. If the last
commit is not a safe commit, a replica will immediately fallback to the
file based sync which is more expensive than the sequence based
recovery. This commit modifies the peer-recovery in replica to start

target if the recovery is sequence based recovery.
Relates #10708
We are targeting to always have a safe index once the recovery is done.
This invariant does not hold if the translog is manually truncated by
users because the truncate translog cli resets the global checkpoint to
unassigned. This commit assigns the global checkpoint to the max_seqno
of the last commit when truncating translog. We can only safely do it
because the truncate translog command will generate a new history uuid
for that shard. With a new history UUID, sequence-based recovery between
that shard and other old shards will be disabled.

Releasble locks hold accounting on who holds the lock when assertions

have entered the lock multiple times. Instead, we have to count how many
times the thread has entered the lock and only mark the lock as not held
