* Search: Support of wildcard on docvalue_fields
For consistency with stored_fields, docvalue_fields should support the use of wildcards.
Documentation of doc values fields is updated accordingly.
See also: #26390Closes#26299
This commit changes the query field expansion for query parsers
to not rely on an hardcoded list of field types. Instead we rely on
the type of exception that is thrown by MappedFieldType#termQuery to
include/exclude an expanded field.
Supersedes #31655Closes#31798
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
In our Netty layer we have had to take extra precautions against Netty
catching throwables which prevents them from reaching the uncaught
exception handler. This code has taken on additional uses in NIO layer
and now in the scheduler engine because there are other components in
stack traces that could catch throwables and suppress them from reaching
the uncaught exception handler. This commit is a simple cleanup of the
iterative evolution of this code to refactor all uses into a single
method in ExceptionsHelper.
Today we can only have non-affix settings updated and consumed _together_.
Yet, there are use-cases where two affix settings depend on each other which
makes using the hard without consuming updates together. Unfortunately, there is
not straight forward way to have N settings updated together in a type-safe way
having 2 still serves a large portion of use-cases.
This change allows an engine to recover from its local translog up to
the given seqno. The extended API can be used in these use cases:
When a replica starts following a new primary, it resets its index to
the safe commit, then replays its local translog up to the current
global checkpoint (see #32867).
When a replica starts a peer-recovery, it can initialize the
start_sequence_number to the persisted global checkpoint instead of the
local checkpoint of the safe commit. A replica will then replay its
local translog up to that global checkpoint before accepting remote
translog from the primary. This change will increase the chance of
operation-based recovery. I will make this in a follow-up.

Today `_msearch` doesn't allow modifying the `max_concurrent_shard_requests`
per sub search request. This change adds support for setting this parameter on
all sub-search requests in an `_msearch`.
Relates to #31877
The maximum map count boostrap check can be a hindrance to users that do
not own the underlying platform on which they are executing
Elasticsearch. This is because addressing it requires tuning the kernel
and a platform provider might now allow this, especially on shared
infrastructure. However, this bootstrap check is not needed if mmapfs is
not in use. Today we do not have a way for the user to communicate that
they are not going to use mmapfs. This commit therefore adds a setting
that enables the user to disallow mmapfs. When mmapfs is disallowed, the
maximum map count bootstrap check is not enforced. Additionally, we
fallback to a different default index store and prevent the explicit use
of mmapfs for an index.
This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.
Closes#31835
* INGEST: Move all Pipeline State into IngestService
* Moves all pipeline state into the ingest service
* Retains the existing pipeline store and pipeline execution service as inner classes to make the review easier, they should be flattened out in the next step
* All tests for these classes were copied (and adapted) to the ingest service tests
* This is a refactoring step to enable a clean implementation of a pipeline processor (See #32473)
There are two problems with the scheduler engine today. Both relate to
listeners that throw.
The first problem is that any triggered listener that throws a plain old
exception will cause no additional listeners to be triggered for the
event, and will also cause the scheduler to never be invoked again. This
leads to lost events and is bad.
The second problem is that any triggered listener that throws an error
of the fatal kind will not lead to that error because caught by the
uncaught exception handler. This is because the triggered listener is
executed as a future task under a scheduled thread pool executor. A
throwable there goes caught by the JDK framework and set as the outcome
on the future task. Since we never inspect these tasks for their
outcomes, nor is there a good place to do this, we have to handle these
errors ourselves. To do this, we catch them and dispatch them to the
uncaught exception handler via a forked thread. This is similar to our
handling in Netty.

I'd like to follow this up with more drastic changes that make it
impossible to do this incorrectly but that change is much larger than

All Translog inner closes should happen after tragedy exception is set (#32674)
We faced with the nasty race condition. See #32526
InternalEngine.failOnTragic method has thrown AssertionError.
If you carefully look at if branches in this method, you will spot that its only possible, if either Lucene IndexWriterhas closed from inside or Translog, has closed from inside, but tragedy exception is not set.
For now, let us concentrate on the Translog class.
We found out that there are two methods in Translog - namely rollGeneration and trimOperations that are closing Translog in case of Exception without tragedy exception being set.
This commit fixes these 2 methods. To fix it, we pull tragedyException from TranslogWriter up-to Translog class, because in these 2 methods IndexWriter could be innocent, but still Translog needs to be closed. Also, tragedyException is wrapped with TragicExceptionHolder to reuse CAS/addSuppresed functionality in Translog and TranslogWriter.
Also to protect us in the future and make sure close method is never called from inside Translog special assertion examining stack trace is added. Since we're still targeting Java 8 for runtime - no StackWalker API is used in the implementation.
In the stack-trace checking method, we're considering inner caller not only Translog methods but Translog child classes methods as well. It does mean that Translog is meant for extending it, but it's needed to be able to test this method.
Closes#32526
This is related to #32517. This commit passes the DiscoveryNode to the
initiateChannel method for different Transport implementation. This
will allow additional attributes (besides just the socket address) to be
used when opening channels.
Randomized test conditions that cause some shards to have no docs on them
failed due to test asserts that relied on a lazy initialization side effect
from the map script. After this fix:
- Test cases with the relevant init script are protected
- Test cases with the relevant combine or reduce scripts were already
protected, because the combine and reduce scripts safely handle this case.
This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.

Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.
This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.

Closes#32927
testDocStats test is flaky and sometimes it's failing on jenkins and
failure is not reproducible locally. The reason for this failure is in
timing. If the number of deleted documents is greater than 33% of inserted
documents, Lucene will schedule segments to merge if TieredMergePolicy is
used (it's not the case for LogMergePolicy, but ES is only using
TieredMergePolicy). If this merge is performed before stats are
retrieved - we will get 0 for "deleted" counter.
So basically this counter could be either 0 or numOfDeletedDocs at this point,
but this is the too loose assertion and we decided to remove it at all.
Closes#32766
This commit disables the automatic `refresh_interval` in order to ensure
that index readers cannot differ between the normal and scroll search.
This issue is related to the 7.5 Lucene upgrade which contains a change that
makes single segment merge more likely to occur (max deletes percentage).
Closes#32682
We do not support passphrases on the secure settings storage (the
keystore). Yet, we added support for this in the API layer. This commit
removes this support so that we are not limited in our future options,
or have to make a breaking change.
This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

Fix global checkpoint listeners test
HLRC: adding machine learning open job (#32860)
[ML] Add log structure finder functionality (#32788)
INGEST: Add Configuration Except. Data to Metdata (#32322)
This commit fixes a global checkpoint listeners test wherein we were
expecting an executor to have been used even if there were no
listeners. This is silliness, so this commit adjusts the assertion to
verify that the executor never fires if there are no listeners, and
fires exactly once if there is one or more listeners.
This commit introduces the ability for global checkpoint listeners to be
registered at the shard level. These listeners are notified when the
global checkpoint is updated, and also when the shard closes. To
encapsulate these listeners, we introduce a shard-level component that
handles synchronization of notification and modifications to the
collection of listeners.
This is related to #31835. It moves the default connection profile into
the ConnectionManager class. The will allow us to have different
connection managers with different profiles.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This commit adds a java time version of the existing rounding classes, which features the same test suite and a small test class to check if serialization works as expected.
Significance score doubles were being parsed as long. Existing tests did not catch this because SignificantLongTermsTests and SignificantStringTermsTests did not set the score. Fixed these and also added integration test.
Thanks for the report/fix, Blakko

#31821 introduced an unreleased bug where NOOP updates were incorrectly mutating the bulk

Closes#32808
This is related to #31835. This commit adds a connection manager that
manages client connections to other nodes. This means that the
TcpTransport no longer maintains a map of nodes that it is connected
to.
With the move to java time, the default formatter used by toString on
ZonedDateTime uses optional components for least significant portions of
the date. This commit changes the cat indices api to use a strict date
time format, which will always output milliseconds, even if they are
zero.
closes#32466
Currently AbstractBuilderTestCase generates certain random values in its
`beforeTest()` method annotated with @Before only the first time that a test
method in the suite is run while initializing the serviceHolder that we use for
the rest of the test. This changes the values of subsequent random values
and has the effect that when running single methods from a test suite with
"-Dtests.method=*", the random values it sees are different from when the same
test method is run as part of the whole test suite. This makes it hard to use
the reproduction lines logged on failure.
This change runs the inialization of the serviceHolder and the randomization
connected to it using the test runners master seed, so reproduction by running
just one method is possible again.
Closes#32400
Processing bulk request goes item by item. Sometimes during processing, we need to stop execution and wait for a new mapping update to be processed by the node. This is currently achieved by throwing a `RetryOnPrimaryException`, which is caught higher up. When the exception is caught, we wait for the next cluster state to arrive and process the request again. Sadly this is a problem because all operations that were already done until the mapping change was required are applied again and get new sequence numbers. This in turn means that the previously issued sequence numbers are never replicated to the replicas. That causes the local checkpoint of those shards to be stuck and with it all the seq# based infrastructure.
This commit refactors how we deal with retries with the goal of removing `RetryOnPrimaryException` and `RetryOnReplicaException` (not done yet). It achieves so by introducing a class `BulkPrimaryExecutionContext` that is used the capture the execution state and allows continuing from where the execution stopped. The class also formalizes the steps each item has to go through:
1) A translation phase for updates
2) Execution phase (always index/delete)
3) Waiting for a mapping update to come in, if needed
4) Requires a retry (for updates and cases where the mapping are still not available after the put mapping call returns)
5) A finalization phase which allows updates to the index/delete result to an update result.
This adds a java time based date math parser class in order, which will replace the joda date based one in the future. For now the class also returns the date in milliseconds since the epoch.
Currently if a document cannot be indexed because it violates the defined
mapping for the index, a MapperException is thrown. In some cases it is
useful to expose the expected field type in the exception itself,
so that the user can react based on the error message. This change adds
the expected data type to the MapperException.
Closes#31502
Remove a few of the logger constructors that aren't widely used or
aren't used at all and deprecate a few more logger constructors in favor
of log4j2's `LogManager`.
A bug in the test suite prevented to properly check that all date
formatters printed the date the same way like joda time does.
This fixes the test and thus also a fair share of formats, that
now use the strict parser for printing.
We previously discussed moving the classes extending `AcknowledgedResponse` to
simply use `AcknowledgedResponse`, making the class non-abstract.
This moves the first class to do this, removing `WritePipelineResponse` in the
process.
If we like the way this looks, I will switch the remaining classes over to using
`AcknowledgedResponse`.
When Circuit Breaker has tripped, certain diagnostic requests like
"_cluster/health" succeed where as request to / fails with

Added / to circuit breaker whitelist so that it can be used for
diagnostic purposes
* Fixes suggestion generics
This solves a compile problem in Eclipse where Eclipse could not
resolve the generics for the options field in `PhraseSuggestion.Entry`.
But I think this is also a good change in general because
`PhraseSuggestion.Entry` is now declaring the specific `Option`
implementation it requires rather than `Suggest.Entry.Option` which is
more general and could lead to weird bugs. `CompletionSuggestion.Entry`
and `TermSuggestion.Entry` already declare the more specific class they
use so I think this was an oversight in `PhaseSuggestion.Entry`
* iter
`ShardOperationFailedException` and corresponding implementors seem to suggest that the cause may be null, case that is also handled in a few places. Yet, it does not seem to be possible in practice for the cause to be null, hence we can clean that up and enforce the cause to be a non null value. This is best done by making `ShardOperationFailedException` an abstract class rather than an interface, which holds the basic member instance that all the subclasses have in common and can also enforce that cause, status and reason are non null.
As part of #32608 we made sure that the fully qualified index name is taken from the query shard context whenever creating a new `QueryShardException`. That change introduced a regression as instead of setting the entire `Index` object to the exception, which holds index name and index uuid, we ended up setting only the index name (including cluster alias). With this commit we make sure that the index uuid does not get lost and we try to lower the chances that a similar bug makes it in another time. That's done by making `QueryShardContext` return the fully qualified `Index` (which also holds the uuid) rather than only the fully qualified index name.
Suggestion responses were previously serialized as streamables which
made writing suggesters in plugins with custom suggestion response types
impossible. This commit makes them serialized as named writeables and
provides a facility for registering a reader for suggestion responses
when registering a suggester.
This also makes Suggestion responses abstract, requiring a suggester
implementation to provide its own types. Suggesters which do not need
anything additional to what is defined in Suggest.Suggestion should
provide a minimal subclass.
The existing plugin suggester integration tests are removed and
replaced with an equivalent implementation as an example
plugin.
It will be useful for future efforts to know if the global checkpoint
was updated. To this end, we need to expose whether or not the global
checkpoint was updated when the state of the replication tracker
updates. For this, we add to the tracker a callback that is invoked
whenever the global checkpoint is updated. For primaries this will be
invoked when the computed global checkpoint is updated based on state
changes to the tracker. For replicas this will be invoked when the local
knowledge of the global checkpoint is advanced from the primary.
The MockNioTransport (similar to the MockTcpTransport) is used for integ
tests. The MockTcpTransport has always only opened a single for all of
its work. The MockNioTransport has awlays opened the default number of
connections (13). This means that every test where two transports
connect requires 26 connections. This is more than is necessary. This
commit modifies the MockNioTransport to only require 3 connections.
Primary terms were introduced as part of the sequence-number effort (#10708) and added in ES
5.0. Subsequent work introduced the replication tracker which lets the primary own its replication
group (#25692) to coordinate recovery and replication. The replication tracker explicitly exposes
whether it is operating in primary mode or replica mode, independent of the ShardRouting object
that's associated with a shard. During a primary relocation, for example, the primary mode is
transferred between the primary relocation source and the primary relocation target. After
transferring this so-called primary context, the old primary becomes a replication target and the
new primary the replication source, reflected in the replication tracker on both nodes. With the
most recent PR in this area (#32442), we finally have a clean transition between a shard that's
operating as a primary and issuing sequence numbers and a shard that's serving as a replication
target. The transition from one state to the other is enforced through the operation-permit system,
where we block permit acquisition during such changes and perform the transition under this
operation block, ensuring that there are no operations in progress while the transition is being
performed. This finally allows us to turn the best-effort checks that were put in place to prevent
shards from being used in the wrong way (i.e. primary as replica, or replica as primary) into hard
assertions, making it easier to catch any bugs in this area.
Currently, when TranslogCorruptedException is thrown most of the times it does not contain information about the translog location on the file system. There is the translog recovery tool that accepts the translog path as an argument and users are constantly puzzled where to get the path.
This pull request adds "source" information to every TranslogCorruptedException thrown. The source could be local file, remote translog source (used for recovery), assertion (translog entry is constructed to perform some assertion) or translog constructed inside the test.
Closes#24929
This change adds a check so that when parsing the search source, script fields are
ignored when the requested search result size is 0. This helps with e.g. clients like
Kibana that sends a list of script fields that they may need for convenience, but they
don't require any hits. Before this change, user sometimes ran into confusing behaviour,
e.g. the script compilation limit to breaking although no hits were requested.
Closes#31824
* We were comparing the wrong timeout value in the `randomValueOtherThan` call here, leading to no mutation happening for a certain seed
* closes#32639
Today content type detection on an input stream works by peeking up to
twenty bytes into the stream. If the stream is headed by more whitespace
than twenty bytes, we might fail to detect the content type. We should
be ignoring this whitespace before attempting to detect the content
type. This commit does that by ignoring all leading whitespace in an
input stream before attempting to guess the content type.
The assertion in the test was not broad enough. If the timing is very unlucky, the
shard is already promoted to primary before the indexOnReplica even gets to execute.

When some remote clusters return shard failures as part of a cross-cluster search request, the cluster alias currently gets lost. As a result, if the shard failures are all caused by the same error, and against indices belonging to different clusters, but with the same index name, only one failure gets returned as part of the search response, meaning that failures are grouped by index name, ignoring the cluster alias.
With this commit we make sure that `ShardSearchFailure` returns the cluster alias as part of the index name. Also, we set the fully qualfied index name when creating a `QueryShardException`. That way shard failures are grouped by cluster:index. Such fixes should cover at least most of the cases where either 1) the shard target is set but we don't have the index in the cause (we were previously reading it only from the cause that did not have the cluster alias) 2) the shard target is missing but if the cause is a `QueryShardException` the cluster alias does not get lost.
We also prevent NPE in case the failure cause is not set and test such scenario.
If the shard is already closed while bumping the primary term, this can result in an
AlreadyClosedException to be thrown. As we use asyncBlockOperations, the exception
will be thrown on a thread from the generic thread pool and end up in the uncaught
exception handler, failing our tests.

linked below), leading to the discovery of a race between resetting a replica when it learns about a
higher term and when the same replica is promoted to primary. This commit fixes the race by
distinguishing between a cluster state primary term (called pendingPrimaryTerm) and a shard-level
operation term. The former is set during the cluster state update or when a replica learns about a
new primary. The latter is only incremented under the operation block, which can happen in a
delayed fashion. It also solves the issue where a replica that's still adjusting to the new term
receives a cluster state update that promotes it to primary, which can happen in the situation of
multiple nodes being shut down in short succession. In that case, the cluster state update thread
would call `asyncBlockOperations` in `updateShardState`, which in turn would throw an exception
as blocking permits is not allowed while an ongoing block is in place, subsequently failing the shard.
This commit therefore extends the IndexShardOperationPermits to allow it to queue multiple blocks
(which will all take precedence over operations acquiring permits). Finally, it also moves the primary
activation of the replication tracker under the operation block, so that the actual transition to
primary only happens under the operation block.

Unmuting the test and adding some more debug output. Was not able to
reproduce the prior failure, but it seems possible that the
failure (mismatched counts) could be caused by partial search results
during the test.
The assertions check for shard failures first, because if one of the
two searches is partial the rest of the test will fail.
Next, instead of just checking respective hit counts, we emit the
difference in hits to help identify what went wrong.
Closes#32492
Since LUCENE-8263, testRecoveryWithOutOfOrderDelete may trigger merges
because of the deletes. In the test, we try to retain index#0 but
reclaim delete#1. However, if a merge is triggered, we will remove both
index#0 and delete#1.
This commit disables merges in this test. Another option is to index
more documents in the segment_2 to reduce the deletion ratio.
Since LUCENE-8263, testSeqNoAndCheckpoints might trigger merges because
of the updates and deletes in the test. Our merge scheduler will trigger
a flush if there is no pending merge. Those extra flushes will change
the last committed segmentInfos in the engine and fail the test.
This commit uses LogMergePolicy for the engine in the test to avoid
merges.
Closes#32430
This commit adds a boolean system property, `es.scripting.use_java_time`,
which controls the concrete return type used by doc values within
scripts. The return type of accessing doc values for a date field is
changed to Object, essentially duck typing the type to allow
co-existence during the transition from joda time to java time.
This removes a constructor from `AbstractComponent` and
`AbstractLifecycleComponent` that we weren't using and it switches the
logger creation away from one of the `Settings` flavored methods which
are no longer needed.
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.
Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```
The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```
Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```
The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.
This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.
Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.
When using cross-cluster search through the high-level REST client, the cluster alias from each search hit was not parsed correctly. It would be part of the index field initially, but overridden just a few lines later once setting the shard target (in case we have enough info to build it from the response). In any case, getClusterAlias returns `null` which is a bug.
With this change we rather parse back clusterAliases from the index name, set its corresponding field and properly handle the two possible cases depending on whether we can or cannot build the shard target object.
The method for working out whether a polygon is clockwise or anticlockwise is
mostly correct but doesn't work in some rare cases such as the included test
case. This commit fixes that.
Rollover should not swap aliases when `is_write_index` is set to `true`.
Instead, both the new and old indices should have the rollover alias,
with the newly created index as the new write index
Updates Rollover to leverage the ability to preserve aliases and swap which is the write index.
Historically, Rollover would swap which index had the designated alias for writing documents against. This required users to keep a separate read-alias that enabled reading against both rolled over and newly created indices, whiles the write-alias was being re-assigned at every rollover.
With the ability for aliases to designate a write index, Rollover can be a bit more flexible with its use of aliases.
Updates include:
- Rollover validates that the target alias has a write index (the index that is being rolled over). This means that the restriction that aliases only point to one index is no longer necessary.
- Rollover explicitly (and atomically) swaps which index is the write-index by explicitly assigning the existing index to have `is_write_index: false` and have the newly created index have its rollover alias as `is_write_index: true`. This is only done when `is_write_index: true` on the write index. Default behavior of removing the alias from the rolled over index stays when `is_write_index` is not explicitly set
Relevant things that are staying the same:
- Rollover is rejected if there exist any templates that match the newly-created index and configure the rollover-alias
- I think this existed to prevent the situation where an alias pointed to two indices for a short while. Although this can technically be relaxed, the specific cases that are safe are really particular and difficult to reason, so leaving the broad restriction sounds good
* Ensure decryption related exceptions are handled
This commit ensures that all possible Exceptions in
KeyStoreWrapper#decrypt() are handled. More specifically, in the
case that a wrong password is used for secure settings, calling readX
on the DataInputStream that wraps the CipherInputStream can throw an
IOException. It also adds a test for loading a KeyStoreWrapper with
a wrong password.
Resolves#32411
Today when reading operation history in Lucene, we read all documents.
However, if indexing a document is aborted, IndexWriter will hard-delete
it; we, therefore, need to exclude that document from Lucene history.
This commit makes sure that we exclude aborted documents by using the
hard liveDocs of a SegmentReader if there are deletes.

[CI] Mute DocumentSubsetReaderTests testSearch
In rare cases it is possible that a nodes gets an instruction to replace a replica
shard that's in `POST_RECOVERY` with a new initializing primary with the same allocation id.
This can happen by batching cluster states that include the starting of the replica, with
closing of the indices, opening it up again and allocating the primary shard to the node in
question. The node should then clean it's initializing replica and replace it with a new
initializing primary.
I'm not sure whether the test I added really adds enough value as existing tests found this. The main reason I added is to allow for simpler reproduction and to double check I fixed it. I'm open to discuss if we should keep.
Closes#32308
`GetResult` and `SearchHit` have been adjusted to parse back the `_ignored` meta field whenever it gets printed out. Expanded the existing tests to make sure this is covered. Fixed also a small problem around highlighted fields in `SearchHitTests`.

Due to the recent change in LUCENE-8263, we need to adjust the deletion
ration to between 10% to 33% to preserve the current behavior of the
test. However, we may need another refinement if soft-deletes is enabled
as the actual deletes are different because of delete tombstones.
This commit prefers to always execute forceMerge instead of adjusting
the deletion ratio so that this test can focus on testing docStats.
Closes#32449
Due to the recent change in LUCENE-8263, a merge can be triggered if the
deletion ration is higher than 33%. An in-progress merge can prevent a
synced-flush from issuing.

Today it's possible to encounter an Index operation in Lucene whose
_source is disabled, and _recovery_source was pruned by the MergePolicy.
If it's the case, we create a Translog#Index without source and let the
caller validate it later. However, this approach is challenging for the
caller.
Deletes and No-Ops don't allow invoking "source()" method. The caller
has to make sure to call "source()" only on index operations. The
current implementation in CCR does not follow this and fail to replica
deletes or no-ops. Moreover, it's easier to reason if a Translog#Index
always has the source.
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.
This commit changes the randomization to always create an index with a type.
It also adds a way to create a query shard context that maps to an index with
no type registered in order to explicitely test cases where there is no type.
* Using short script form normalized to a map that used 'inline' instead of 'source' so a short form processor definition like:
```
{
"script": "ctx.foo= 'bar'"
}
```
would always warn about the following deprecation:
```
#! Deprecation: Deprecated field [inline] used, expected [source]
```
In testSyncedFlushSkipOutOfSyncReplicas, we reindex the extra documents
to all shards including the out-of-sync replica. However, reindexing to
that replica can trigger merges (due to the new deletes) which cause the
synced-flush failed. This test starts failing after we aggressively
trigger merges segments with a large number of deletes in LUCENE-8263.
Removing some dead code or supressing warnings where apropriate. Most of the
time the variable tested for null is dereferenced earlier or never used before.
Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.
An upcoming [Lucene change](https://issues.apache.org/jira/browse/LUCENE-7976)
will make TieredMergePolicy respect the maximum merged segment size all the
time, meaning it will possibly not respect the `max_num_segments` parameter
anymore if the shard is larger than the maximum segment size.
This change makes sure that `max_num_segments` is respected for now in order
to give us time to think about how to integrate this change, and also to delay
it until 7.0 as this might be a big-enough change for us to wait for a new
major version.

This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges

Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

Currently we check that the queries that QueryStringQueryBuilder#toQuery returns
is one out of a list of many Lucene query classes. This list has extended a lot over time,
since QueryStringQueryBuilder can build all sort of queries. This makes the test hard to
maintain. The recent addition of alias fields which build a BlendedTermQuery show how
easy this test breaks. Also the current assertions doesn't add a lot in terms of catching
errors. This is why we decided to remove this check.
Closes#32234
The parent filter for nested sort should always match **all** parents regardless
of the child queries. It is used to find the boundaries of a single parent and we use
the child query to match all the filters set in the nested tree so there is no need to
repeat the nested filters.
With this change we ensure that we build bitset filters
only to find the root docs (or the docs at the level where the sort applies) that can be reused
among queries.

* Enhance Parent circuit breaker error message
This adds information about either the current real usage (if tracking "real"
memory usage) or the child breaker usages to the exception message when the
parent circuit breaker trips.
The messages now look like:
```
[parent] Data too large, data for [my_request] would be [211288064/201.5mb], which is larger than the limit of [209715200/200mb], usages [request=157286400/150mb, fielddata=54001664/51.5mb, in_flight_requests=0/0b, accounting=0/0b]
```
Or when tracking real memory usage:
```
[parent] Data too large, data for [request] would be [251/251b], which is larger than the limit of [200/200b], real usage: [181/181b], new bytes reserved: [70/70b]
```
* Only call currentMemoryUsage once by returning structured object
Normally translog operations will not be replayed on the primary.
Following engine is an exception where we replay translog on both
primary and replica as a non-primary strategy. Even though we won't use
the version_type in the following engine, we still need to pass a valid
value for the primary operation in order not to trip assertions in an
engine.
This commit passes version_type EXTERNAL for translog operation if its
origin is primary.
Relates #31945
Resolving wildcards in aliases expression is challenging as we may end
up with no aliases to replace the original expression with, but if we
replace with an empty array that means _all which is quite the opposite.
Now that we support and serialize the original requested aliases,
whenever aliases are replaced we will be able to know what was
initially requested. `MetaData#findAliases` can then be updated to not
return anything in case it gets empty aliases, but the original aliases
were not empty. That means that empty aliases are interpreted as _all
only if they were originally requested that way.

Now write operations like Index, Delete, Update rely on the write-index associated with
an alias to operate against. This means writes will be accepted even when an alias points to multiple indices, so long as one is the write index. Routing values will be used from the AliasMetaData for the alias in the write-index. All read operations are left untouched.

Fixes#32154
When a replica is fully recovered (i.e., in `POST_RECOVERY` state) we send a request to the master
to start the shard. The master changes the state of the replica and publishes a cluster state to that
effect. In certain cases, that cluster state can be processed on the node hosting the replica
*together* with a cluster state that promotes that, now started, replica to a primary. This can
happen due to cluster state batched processing or if the master died after having committed the
cluster state that starts the shard but before publishing it to the node with the replica. If the master
also held the primary shard, the new master node will remove the primary (as it failed) and will also
immediately promote the replica (thinking it is started).
Sadly our code in IndexShard didn't allow for this which caused [assertions](13917162ad/server/src/main/java/org/elasticsearch/index/seqno/ReplicationTracker.java (L482)) to be tripped in some of our tests runs.
With the introduction of single types in 6.x, the `_type` field is no longer
indexed, which leads to certain queries that were working before throw errors
now. One such query is the `range` query, that, if performed on a single typer
index, currently throws an IAE since the field is not indexed.
This change adds special treatment for this case in the TypeFieldMapper,
comparing the range queries lower and upper bound to the one existing type and
either returns a MatchAllDocs or a MatchNoDocs query.
Relates to #31632Closes#31476
With the introduction of sequence number, we no longer use versionType to
resolve out of order collision in replication and recovery requests.
This PR removes removes the versionType from translog. We can only remove
it in 7.0 because it is still required in a mixed cluster between 6.x and 5.x.
This commit moves additional unit test runners from being dependencies
of the test task to dependencies of check. Without this change,
reproduce lines are incorrect due to the additional test runner not
matching any of the reproduce class/method info.

Previously we create a translog snapshot inside the resync method,

Closes#32030
Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.
IT will be covered in a subsequent PR
The current docs of the put-mapping Java API is currently broken. It its current
form, it creates an index and uses the whole mapping definition given as a JSON
string as the type name. Since we didn't check the index created in the
IndicesDocumentationIT so far this went unnoticed.
This change adds test to catch this error to the documentation test, changes the
documentation so it works correctly now and adds an input validation to
PutMappingRequest#buildFromSimplifiedDef() which was used internally to reject
calls where no mapping definition is given.

With this commit we raise the limit of the child circuit breaker used in
the unit test for the circuit breaker service so it is high enough to trip
only the parent circuit breaker. The previous limit was 300 bytes but
theoretically (considering overhead) we could reach 346 bytes. Thus any
value larger than 300 bytes could trip the child circuit breaker leading
to spurious failures.

* Adds a new auto-interval date histogram
This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.
This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.

Added some notes in the documentation about the intervals that can bbe

Also added a test case that utilises the merging of conseecutive buckets
* Fixes performance bug
The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).
The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.
Thee commit also adds more tests

* fix typo
Because this is a static method on a public API, and one that we encourage
plugin authors to use, the method with the typo is deprecated in 6.x
rather than just renamed.
With this commit we introduce a new circuit-breaking strategy to the parent
circuit breaker. Contrary to the current implementation which only accounts for
memory reserved via child circuit breakers, the new strategy measures real heap
memory usage at the time of reservation. This allows us to be much more
aggressive with the circuit breaker limit so we bump it to 95% by default. The
new strategy is turned on by default and can be controlled with the new cluster
setting `indices.breaker.total.userealmemory`.
Note that we turn it off for all integration tests with an internal test cluster
because it leads to spurious test failures which are of no value (we cannot
fully control heap memory usage in tests). All REST tests, however, will make
use of the real memory circuit breaker.

The current shard follow mechanism is complex and does not give us easy ways the have visibility into the system (e.g. why we are falling behind).
The main reason why it is complex is because the current design is highly asynchronous. Also in the current model it is hard to apply backpressure
other than reducing the concurrent reads from the leader shard.
This PR has the following changes:
* Rewrote the shard follow task to coordinate the shard follow mechanism between a leader and follow shard in a single threaded manner.
This allows for better unit testing and makes it easier to add stats.
* All write operations read from the shard changes api should be added to a buffer instead of directly sending it to the bulk shard operations api.
This allows to apply backpressure. In this PR there is a limit that controls how many write ops are allowed in the buffer after which no new reads
will be performed until the number of ops is below that limit.
* The shard changes api includes the current global checkpoint on the leader shard copy. This allows reading to be a more self sufficient process;
instead of relying on a background thread to fetch the leader shard's global checkpoint.
* Reading write operations from the leader shard (via shard changes api) is a separate step then writing the write operations (via bulk shards operations api).
Whereas before a read would immediately result into a write.
* The bulk shard operations api returns the local checkpoint on the follow primary shard, to keep the shard follow task up to date with what has been written.
* Moved the shard follow logic that was previously in ShardFollowTasksExecutor to ShardFollowNodeTask.
* Moved over the changes from #31242 to make shard follow mechanism resilient from node and shard failures.
Relates to #30086
The initial check will never be true, because of the special semantics of NaN,
where no value is equal to Nan, including NaN. Thus, x == Double.NaN always
evaluates to false. The method still works correct because later computations
will also return NaN if the avg argument is NaN, but the intended shortcut
doesn't work.
A newly added class called DateFormatters now contains java.time based
builders for dates, which also intends to be fully backwards compatible,
when the name based date formatters are picked. Also a new class named
CompoundDateTimeFormatter for being able to parse multiple different
formats has been added.
A duelling test class has been added that ensures the same dates when
parsing java or joda time formatted dates for the name based dates.
Note, that java.time and joda time are not fully backwards compatible,
which also means that old formats will currently not work with this
setup.

Fix handling of points_only with term strategy in geo_shape (#31766)
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 is a second attempt to fix this (first attempt was #28294).
The reason that the first attempt was reverted is because when xpack
security is enabled then index expression (like * or _all) are resolved
prior to when a request is processed in the get aliases transport action,
then `MetaData#findAliases` can't know whether requested all where
requested since it was already expanded in concrete alias names. This
change replaces aliases(...) replaceAliases(...) method on AliasesRequests
class and leave the aliases(...) method on subclasses. So there is a distinction
between when xpack security replaces aliases and a user setting aliases via
the transport or high level http client.
Closes#27763
This is a followup to #31537. It makes a number of changes requested by
a review that came after the PR was merged. These are mostly cleanups
and doc improvements.
Fixes 2 issues that together cause errors during index creation
with geo_shapes that use the term strategy. The term strategy changes
the default for points_only parameter, but this wasn't taken into
account during serialization. So, setting the term strategy would add
`"points_only": true` to serialization. At the same time if the term
strategy would also cause the `points_only` setting to be not marked as
a processed element during parsing, which would cause index creation to
fail with the error: `Mapping definition for [location] has unsupported`
`parameters: [points_only : true]`.

Fix TransportChangePasswordActionTests
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
The Rectangle constructor validates bounds before coerce has a chance

This commit removes the Rectangle as an intermittent storage for the

AWS supports the creation and use of credentials that are only valid for a
fixed period of time. These credentials comprise three parts: the usual access
key and secret key, together with a session token. This commit adds support for
these three-part credentials to the EC2 discovery plugin and the S3 repository
plugin.
Note that session tokens are only valid for a limited period of time and yet
there is no mechanism for refreshing or rotating them when they expire without
restarting Elasticsearch. Nonetheless, this feature is already useful for
nodes that need only run for a few days, such as for training, testing or
evaluation. #29135 tracks the work towards allowing these credentials to be
refreshed at runtime.
Resolves#16428
This PR does the server side work for adding the Get Index API to the REST
high-level-client, namely moving resolving default settings to the
transport action. A follow up would be the client side changes.
So far the in-flight request circuit breaker has only accounted for the
on-the-wire representation of a request. However, we convert the raw
request into XContent internally which increases the overhead.
Therefore, we increase the value of the corresponding setting
`network.breaker.inflight_requests.overhead` from one to two. While this
value is still rather conservative (we assume that the representation as
structured objects has no overhead compared to the byte[]), it is closer
to reality than the current value.
Relates #31613
`MemoryCircuitBreakerTests` conflates two test aspects: It tests
individual circuit breakers as well as the circuit breaker hierarchy.
With this commit we split those two aspects into two test classes:
* Tests for individual circuit breakers stay in the current class
* Other tests are moved to `HierarchyCircuitBreakerServiceTests`
Adds a new parameter to the BlobContainer#write*Blob methods to specify whether the existing file
should be overridden or not. For some metadata files in the repository, we actually want to replace
the current file. This is currently implemented through an explicit blob delete and then a fresh write.
In case of using a cloud provider (S3, GCS, Azure), this results in 2 API requests instead of just 1.
This change will therefore allow us to achieve the same functionality using less API requests.

Before deleting a repository index generation file, BlobStoreRepository
checks for the existence of the file and then deletes it. We can save
a request here by using BlobContainer.deleteBlobIgnoringIfNotExists()
which ignores error when deleting a file that does not exist.
Since there is no way with S3 to know if a non versioned file existed
before being deleted, this pull request also changes S3BlobContainer so
that it now implements deleteBlobIgnoringIfNotExists(). It will now save
one more request (blobExist?) when appropriate. The tests and fixture
have been modified to conform the S3 API that always returns a 204/NO
CONTENT HTTP response on deletions.
If the recovery and indexing are concurrently happening, it's possible
for a replica to receive the same operation twice: one from the
replication, and the other from the recovery. However, these operations
are not identical because we don't store the versionType of operations
in the Lucene index.
The TranslogWriter#assertNoSeqNumberConflict assertion has been tripped
several times in the CCR branch since we use Lucene in peer-recovery.
This commit relaxes that assertion by excluding the versionType from the
check.
Make password hashing algorithm/cost configurable for the
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are
whitelisted and can be selected in the relevant setting.
The TaskManager and TaskAwareRequest could return null when registering
a task according to their javadocs, but no implementations ever actually
did that. This commit removes that wording from the javadocs and ensures
null is no longer allowed.

Today we use INTERNAL version type for the history operations from

original operation has the version type EXTERNAL and version number 0.
Semantically all operations from translog or Lucene should always use
EXTERNAL version type.
* Remove deprecation warnings to prepare for Gradle 5
Gradle replaced `project.sourceSets.main.output.classesDir` of type
`File` with `project.sourceSets.main.output.classesDirs` of type
`FileCollection`
(see [SourceSetOutput](https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/java/org/gradle/api/tasks/SourceSetOutput.java))
Build output is now stored on a per language folder.
There are a few places where we use that, here's these and how it's
fixed:
- Randomized Test execution
- look in all test folders ( pass the multi dir configuration to the
ant runner )
- DRY the task configuration by introducing `basedOn` for
`RandomizedTestingTask` DSL
- Extend the naming convention test to support passing in multiple
directories
- Fix the standalon test plugin, the dires were not passed trough,
checked with a debuger and the statement had no affect due to a
missing `=`.
Closes#30354
* Only check Java tests, PR feedback
- Name checker was ran for Groovy tests that don't adhere to the same
convections causing the check to fail
- implement PR feedback
* Replace `add` with `addAll`
This worked because the list is passed to `project.files` that does the
right thing.
* Revert "Only check Java tests, PR feedback"
This reverts commit 9bd9389875d8b88aadb50df57a45cd0d2b073241.
* Remove `basedOn` helper
* Bring some changes back
Previus revert accidentally reverted too much

* revert name check changes
* Revert "revert name check changes"
This reverts commit a2800c0b363168339ea65e2a79ec8256e5883e6d.
* Pass all dirs to name check
Only run on Java for build-tools, this is safe because it's a self test.
It needs more work before we could pass in the Groovy classes as well as
these inherit from `GroovyTestCase`
* remove self tests from name check
The self complicates the task setup and disable real checks on
build-tools.
With this change there are no more self tests, and the build-tools tests
adhere to the conventions.
The self test will be replaced by gradle test kit, thus the addition of
the Gradle plugin builder plugin.

* Add tests that replace the name check self test

Relates to #31324. It seems like Gradle has an inconsistent behavior and
the taks is not always replaced.
* Include number of non conforming tasks in the exception.
* No longer replace test task, create implicit instead
Closes#31324. The issue has full context in comments.
With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.
* Revert "No longer replace test task, create implicit instead"
This reverts commit f1ebaf7d93e4a0a19e751109bf620477dc35023c.
* Fix replacement of the test task

With PR #31574 we now ensure that connections are established under the proper
thread context. There is a test in RemoteClusterConnectionTests, however,
that shuts down the service while connecting. With the above change, a new kind
of exception can occur that the test is unaware of.
Added support to the high-level rest client for the create snapshot API call. This required
several changes to toXContent which may need to be cleaned up in a later PR. Also
added several parsers for fromXContent to be able to retrieve appropriate responses
along with tests.
Establishing remote cluster connections uses a queue to coordinate multiple concurrent connect
attempts. Connect attempts can be initiated by user triggered searches as well as by system events
(e.g. when nodes disconnect). Multiple such concurrent events can lead to the connectListener of
one event to be called under the thread context of another connect attempt. This can lead to the
situation as seen in #31462 where the connect listener is executed under the system context, which
breaks when fetching the search shards from the remote cluster.

Currently RandomObjects::addFields can potentially generate a large number of fields This commit decreases the chances that a new object or array is added as a new branch of an object, which lowers the probability of ending up with very big documents generated. It also reduces the number of documents generated for the SimulatePipelineResponseTests from 10 to 5 to reduce the testing time required for parsing.
This commit enhances the assertion message when de-duplicating values on
a thread context header so that if this assertion trips we can see the
values and their correpsonding unique values to understand why this
assertion might trip.
AliasOrIndex.Alias#writeIndex was returning a write index when
an alias was pointing to only one index, regardless whether `is_write_index` was
set to `false`. This fixes that so that there is no write index in such a case
that an alias points to only one index with `is_write_index=false`.

TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
Introduces support for multiple host providers, which allows the settings based hosts resolver to be
treated just as any other UnicastHostsProvider. Also introduces the notion of a HostsResolver so
that plugins such as FileBasedDiscovery do not need to create their own thread pool for resolving
hosts, making it easier to add new similar kind of plugins.
Get Mapping currently throws index not found exception (and returns
404 status code) from the REST layer whenever an index was specified
and no indices have been returned. We should not have this logic in the
REST layer though as only our index resolver should decide whether we
need to throw exceptions or not based on provided indices and corresponding
indices options.
Closes#31485
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
We renamed `createNewTranslog` to `fileBasedRecovery` in the
RecoveryTarget but did not do this for RecoverySourceHandler.
This commit makes sure that we a consistent parameter in both
recovery source and target.
With #20695 we removed local transport and there is just TransportAddress now. The
UnicastHostsProvider currently returns DiscoveryNode instances, where, during pinging, we're
actually only making use of the TransportAddress to establish a first connection to the possible new
node. To simplify the interface, we can just return a list of transport addresses instead, which
means that it's not necessary anymore to create fake node objects in each plugin just to return the
address information.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.

The QueryCachingPolicy#ALWAYS_CACHE was deprecated in Lucene-7.4 and
will be removed in Lucene-8.0. This change replaces it with QueryCachingPolicy.
This also makes INDEX_QUERY_CACHE_EVERYTHING_SETTING visible in testing only.
The `multiplexer` filter emits multiple tokens at the same position, each
version of the token haivng been passed through a different filter chain.
Identical tokens at the same position are removed.
This allows users to, for example, index lowercase and original-case tokens,
or stemmed and unstemmed versions, in the same field, so that they can search
for a stemmed term within x positions of an unstemmed term.
Currently, DateHistogramAggregationBuilder#rewriteTimeZone uses the aggregation
date math parser and time zone to check whether all values in a read have the
same timezone to speed up computation. However, the upper and lower bounds to
check are retrieved as longs in epoch_millis, so they don't need to get parsed
using a time zone or a parser other than "epoch_millis". This changes this
behaviour that was causing problems when the field type mapping was specifying
only "epoch_millis" as a format but a different timezone than UTC was used.
Closes#31392
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
#31241 changed the cluster state update tasks to run under system context. The context wrapping
did not preserve response headers, though. This has led to a test failure on 6.x #31408, as the
deprecation warnings were not carried back anymore to the caller when creating an index. This
commit changes the restorable context supplier to preserve response headers.
