* [SPATIAL] New ShapeFieldMapper for indexing cartesian geometries (#44980)
Add a new ShapeFieldMapper to the xpack spatial module for
indexing arbitrary cartesian geometries using a new field type called shape.
The indexing approach leverages lucene's new XYShape field type which is
backed by BKD in the same manner as LatLonShape but without the WGS84
latitude longitude restrictions. The new field mapper builds on and
extends the refactoring effort in AbstractGeometryFieldMapper and accepts
shapes in either GeoJSON or WKT format (both of which support non geospatial
geometries).
Tests are provided in the ShapeFieldMapperTest class in the same manner
as GeoShapeFieldMapperTests and LegacyGeoShapeFieldMapperTests.
Documentation for how to use the new field type and what parameters are
accepted is included. The QueryBuilder for searching indexed shapes is
provided in a separate commit.
* [SPATIAL] New ShapeQueryBuilder for querying indexed cartesian geometry (#45108)
Add a new ShapeQueryBuilder to the xpack spatial module for

GeoShapeQueryTests and docs are updated to explain how the query works.

Currently, when adding a new mapping, we attempt to parse + merge it before
checking whether its top-level document type matches the existing type. So when
a user attempts to introduce a new mapping type, we may give a confusing error
message around merging instead of complaining that it's not possible to add
more than one type ("Rejecting mapping update to [my-index] as the final
mapping would have more than 1 type...").
This PR moves the type validation to the start of
`MetaDataMappingService#applyRequest` so that we make sure the type matches
before performing any mapper merging.
We already partially addressed this issue in #29316, but the tests there
focused on `MapperService` and did not catch this problem with end-to-end
mapping updates.
Addresses #43012.
We accidentally introduced this bug when adding a typeless version of the
rollover request. The bug is not present if include_type_name is set to true.
The previous hasProcessors method would validate if a processor was
present within a pipeline, but would not return the contents of the
processors. This does not allow a consumer to inspect the processor for
specific metadata. The method now returns the list of processors based
on the class of the processor passed in.
Because auto-date-histo can perform multiple reductions while
merging buckets, we need to ensure that the intermediate reductions
are done with a `finalReduce` set to false to prevent Pipeline aggs
from generating their output.
Once all the buckets have been merged and the output is stable,
a mostly-noop reduction can be performed which will allow pipelines
to generate their output.
This commit makes sure that mapping parameters to `CreateIndex` and
`PutIndexTemplate` are keyed by the type name.
`IndexCreationTask` expects mappings to be keyed by the type name.
It asserts this for template mappings but not for the mappings in the request.
The `CreateIndexRequest` and `RestCreateIndexAction` mostly make it sure
that the mapping is keyed by a type name, but not always.
When building the create-index request outside of the REST handler, there are
a few methods to set the mapping for the request. Some of them add the type
name some of them do not.
For example, `CreateIndexRequest#mapping(String type, Map<String, ?> source)`
adds the type name, but
`CreateIndexRequest#mapping(String type, XContentBuilder source)` does not.
This PR asserts the type name in the request mapping inside `IndexCreationTask`
and makes all `CreateIndexRequest#mapping` methods add the type name.
testShouldFlushAfterPeerRecovery was added #28350 to make sure the
flushing loop triggered by afterWriteOperation eventually terminates.
This test relies on the fact that we call afterWriteOperation after
making changes in translog. In #44756, we roll a new generation in
RecoveryTarget#finalizeRecovery but do not call afterWriteOperation.

Today, if an operation-based peer recovery occurs, we won't trim
translog but leave it as is. Some unacknowledged operations existing in
translog of that replica might suddenly reappear when it gets promoted.
With this change, we ensure trimming translog above the starting
sequence number of phase 2. This change can allow us to read translog
forward.
* Follow up to #44949
* Stop using a special code path for multi-line JSON and instead handle its detection like that of other XContent types when creating the request
* Only leave a single path that holds a reference to the full REST request
* In the next step we can move the copying of request content to happen before the actual request handling and make it conditional on the handler in question to stop copying bulk requests as suggested in #44564
* Reduces complicated callback relations in `testSuccessfulSnapshotAndRestore` to flat steps of sequential actions
* Will refactor the other tests in this suit as a follow up
* This format certainly makes it easier to create more complicated tests that involve multiple subsequent snapshots as it would allow adding loops
When having a cluster state from 6.x, display the metadata version as the cluster state version.
Avoids confusion where a cluster state from 6.x is displayed as version 0 even if has some actual
content.
Today if a shard is not fully allocated we maintain a retention lease for a
lost peer for up to 12 hours, retaining all operations that occur in that time
period so that we can recover this replica using an operations-based recovery
if it returns. However it is not always reasonable to perform an
operations-based recovery on such a replica: if the replica is a very long way
behind the rest of the replication group then it can be much quicker to perform
a file-based recovery instead.
This commit introduces a notion of "reasonable" recoveries. If an
operations-based recovery would involve copying only a small number of
operations, but the index is large, then an operations-based recovery is
reasonable; on the other hand if there are many operations to copy across and
the index itself is relatively small then it makes more sense to perform a
file-based recovery. We measure the size of the index by computing its number
of documents (including deleted documents) in all segments belonging to the
current safe commit, and compare this to the number of operations a lease is
retaining below the local checkpoint of the safe commit. We consider an
operations-based recovery to be reasonable iff it would involve replaying at
most 10% of the documents in the index.
The mechanism for this feature is to expire peer-recovery retention leases
early if they are retaining so much history that an operations-based recovery
using that lease would be unreasonable.

CellIdSource is a helper ValuesSource that encodes GeoPoint
into a long-encoded representation of the grid bucket the point
is associated with. This complicates thing as usage evolves to
support shapes that are associated with more than one bucket ordinal.
Today the test waits for one of the shards to be blocked, but this does not
mean that the block has been applied on all nodes, so a subsequent indexing
operation may still go through.
Fixes#45338
The client and remote hit sources had each their own retry mechanism,
which would do the same. Supporting resiliency we would have to expand
on the retry mechanisms and as a preparation for that, the retry
mechanism is now shared such that each sub class is only responsible for
sending requests and converting responses/failures to common format.

Refreshes happening during indexing can result differen segment counts and

`newSearcher()` from lucene can randomly choose index readers which

This commit adds a helper method to the ingest service allowing it to
inspect a pipeline by id and verify the existence of a processor in the
pipeline. This work exposed a potential bug in that some processors
contain inner processors that are passed in at instantiation. These
processors needed a common way to expose their inner processors, so the
WrappingProcessor was created in order to expose the inner processor.
If a node exceeds the flood-stage disk watermark then we add a block to all of
its indices to prevent further writes as a last-ditch attempt to prevent the
node completely exhausting its disk space. However today this block remains in
place until manually removed, and this block is a source of confusion for users
who current have ample disk space and did not even realise they nearly ran out
at some point in the past.
This commit changes our behaviour to automatically remove this block when a
node drops below the high watermark again. The expectation is that the high
watermark is some distance below the flood-stage watermark and therefore the
disk space problem is truly resolved.
Fixes#39334
The reason field of DefaultShardOperationFailedException is lost during serialization.
This is sad because this field is checked for nullity during xcontent generation and it
means that the cause won't be included in the generated xcontent and won't be
printed in two REST API responses (Close Index API and Indices Shard Stores API).
This commit simply restores the reason from the cause during deserialization.
Adds a tighter threshold for logging a warning about slowness in the
`MasterService` instead of relying on the cluster service's 30-second warning
threshold. This new threshold applies to the computation of the cluster state
update in isolation, so we get a warning if computing a new cluster state
update takes longer than 10 seconds even if it is subsequently applied quickly.
It also applies independently to the length of time it takes to notify the
cluster state tasks on completion of publication, in case any of these
notifications holds up the master thread for too long.

This commit applies a normalization process to environment paths, both
in how they are stored internally, also their settings values. This
normalization is done via two means:
- we make the paths absolute
- we remove redundant name elements from the path (what Java calls
"normalization")
This change ensures that when we compare and refer to these paths within
the system, we are using a common ground. For example, prior to the
change if the data path was relative, we would not compare it correctly
to paths from disk usage. This is because the paths in disk usage were
being made absolute.
Uses JDK 11's per-socket configuration of TCP keepalive (supported on Linux and Mac), see
https://bugs.openjdk.java.net/browse/JDK-8194298, and exposes these as transport settings.
By default, these options are disabled for now (i.e. fall-back to OS behavior), but we would like
to explore whether we can enable them by default, in particular to force keepalive configurations
that are better tuned for running ES.
This adjusts the `buckets_path` parser so that pipeline aggs can
select specific buckets (via their bucket keys) instead of fetching
the entire set of buckets. This is useful for bucket_script in
particular, which might want specific buckets for calculations.
It's possible to workaround this with `filter` aggs, but the workaround
is hacky and probably less performant.
- Adjusts documentation
- Adds a barebones AggregatorTestCase for bucket_script
- Tweaks AggTestCase to use getMockScriptService() for reductions and
pipelines. Previously pipelines could just pass in a script service
for testing, but this didnt work for regular aggs. The new
getMockScriptService() method fixes that issue, but needs to be used
for pipelines too. This had a knock-on effect of touching MovFn,
AvgBucket and ScriptedMetric
Introduce shift field to MovingFunction aggregation.
By default, shift = 0. Behavior, in this case, is the same as before.
Increasing shift by 1 moves starting window position by 1 to the right.

For right alignment (n values after the current bucket), use shift = window.
* Resolve TODO in `readString` by moving to reading chunks of `byte[]` instead of going byte by byte
* Motivated by `readString` showing up as a significant user of CPU time on the IO thread in Rally PMC benchmark

This commit switches to using the full hash to build into the JAR
manifest, which is used in node startup and the REST main action to
display the build hash.
Currently in the transport-nio work we connect and bind channels on the
a thread before the channel is registered with a selector. Additionally,
it is at this point that we set all the socket options. This commit
moves these operations onto the event-loop after the channel has been
registered with a selector. It attempts to set the socket options for a
non-server channel at registration time. If that fails, it will attempt
to set the options after the channel is connected. This should fix
#41071.

Today we recover a replica by copying operations from the primary's translog.
However we also retain some historical operations in the index itself, as long
as soft-deletes are enabled. This commit adjusts peer recovery to use the
operations in the index for recovery rather than those in the translog, and
ensures that the replication group retains enough history for use in peer
recovery by means of retention leases.

* Stop Passing Around REST Request in Multiple Spots
* Motivated by #44564
* We are currently passing the REST request object around to a large number of places. This works fine since we simply copy the full request content before we handle the rest itself which is needlessly hard on GC and heap.
* This PR removes a number of spots where the request is passed around needlessly. There are many more spots to optimize in follow-ups to this, but this one would already enable bypassing the request copying for some error paths in a follow up.
Sparse role queries are executed differently than other queries in order
to account for the fact that most of the documents are filtered from search.
However this special execution does not set the scorer for the query so any
collector that needs to access the score of a document fails with an NPE.
This change fixed this bug by setting the scorer before collecting any hits
when intersecting the main query and the sparse role.
The Settings#processSetting method is intended to take a setting map and add a
setting to it, adjusting the keys as it goes in case of "conflicts" where the
new setting implies an object where there is currently a string, or vice
versa. processSetting was failing in two cases: adding a setting two levels
under a string, and adding a setting two levels under a string and four levels
under a map. This commit fixes the bug and adds test coverage for the
previously faulty edge cases.

Previously, we use ThreadPoolStats to ensure that the scheduledRefresh
triggered by the internal refresh setting update is executed before we
index a new document. With that change (#40387), this test did not fail for
the last 3 months. However, using ThreadPoolStats is not entirely watertight
as both "active" and "queue" count can be 0 in a very small interval
when ThreadPoolExecutor pulls a task from the queue but before marking
the corresponding worker as active (i.e., lock it).

Today the lag detector may remove nodes from the cluster if they fail to apply
a cluster state within a reasonable timeframe, but it is rather unclear from
the default logging that this has occurred and there is very little extra
information beyond the fact that the removed node was lagging. Moreover the
only forewarning that the lag detector might be invoked is a message indicating
that cluster state publication took unreasonably long, which does not contain
enough information to investigate the problem further.
This commit adds a good deal more detail to make the issues of slow nodes more
prominent:
- after 10 seconds (by default) we log an INFO message indicating that a
publication is still waiting for responses from some nodes, including the
identities of the problematic nodes.
- when the publication times out after 30 seconds (by default) we log a WARN
message identifying the nodes that are still pending.
- the lag detector logs a more detailed warning when a fatally-lagging node is
detected.
- if applying a cluster state takes too long then the cluster applier service
logs a breakdown of all the tasks it ran as part of that process.

Reading up on #33673 it looks like parts of these tests have been reworked and
there is no intention to fix the remains on 7.x, so I think we can remove the
entire test.
The task that TaskManager#register returns cannot be null. The method
enforces that it is not null after calling request#createTask. It is
then needless to check for null in the listener later. Also, added the
call to the delegate listener in a finally block, just to make sure.
* We shouldn't be recreating wrapped REST handlers over and over for every request. We only use this hook in x-pack and the wrapper there does not have any per request state.
This is inefficient and could lead to some very unexpected memory behavior

When finding nodes in a connected cluster for cross cluster
search the requests to get cluster state on the connected
cluster should be made in the system context because
logically they are equivalent to checking a single detail

implementation is authorized to view the entire cluster
state.

Today closing a `ClusterNode` in an `AbstractCoordinatorTestCase` uses
`onNode()` so has no effect if the node is not in the current list of nodes.
It also discards the `Runnable` it creates without having run it, so has no
effect anyway.
This commit makes these tests much stricter about properly closing the nodes
started during `Coordinator` tests, by tracking the persisted states that are
opened, and adds an assertion to catch the trappy requirement that the closing
node still belongs to the cluster.
This commit fixes a bug when a deferred aggregator tries to early terminate the collection. In such case the CollectionTerminatedException is not caught and

We currently block the transport thread on startup, which has caused test failures. I think this is
some kind of deadlock situation. I don't think we should even block a transport thread, and
there's also no need to do so. We can just reject requests as long we're not fully set up. Note
that the HTTP layer is only started much later (after we've completed full start up of the
transport layer), so that one should be completely unaffected by this.

SimpleClusterStateIT testIndicesOptions failed in #44817 because it tries to close

CI this index can take time to be fully allocated.

The test ShrinkIndexIT.testShrinkThenSplitWithFailedNode sometimes fails
because the resize operation is not acknowledged (see #44736). This resize
operation creates a new index "splitagain" and it results in a cluster state
update (TransportResizeAction uses MetaDataCreateIndexService.createIndex()
to create the resized index). This cluster state update is expected to be
acknowledged by all nodes (see IndexCreationTask.onAllNodesAcked()) but
this is not always true: the data node that was just stopped in the test before
executing the resize operation might still be considered as a "faulty" node
(and not yet removed from the cluster nodes) by the FollowersChecker. The
cluster state is then acked on all nodes but one, and it results in a non
acknowledged resize operation.
This commit adds an ensureStableCluster() check after stopping the node in
the test. The goal is to ensure that the data node has been correctly removed
from the cluster and that all nodes are fully connected to each before moving
forward with the resize operation.
Closes#44736
Today the processors setting is permitted to be set to more than the
number of processors available to the JVM. The processors setting
directly sizes the number of threads in the various thread pools, with
most of these sizes being a linear function in the number of
processors. It doesn't make any sense to set processors very high as the
overhead from context switching amongst all the threads will overwhelm,
and changing the setting does not control how many physical CPU
resources there are on which to schedule the additional threads. We have
to draw a line somewhere and this commit deprecates setting processors
to more than the number of available processors. This is the right place
to draw the line given the linear growth as a function of processors in
most of the thread pools, and that some are capped at the number of
available processors already.
With this change, we will return primary_term and seq_no of the current
document if an update is detected as a noop. We already return the

We have some old permissions lying around, granted to untrusted code

Today our systemd service defaults to a service type of simple. This
means that systemd assumes Elasticsearch is ready as soon as the
ExecStart (bin/elasticsearch) process is forked off. This means that the
service appears ready long before it actually is, so before it is ready
to receive requests. It also means that services that want to depend on
Elasticsearch being ready to start can not as there is not a reliable
mechanism to determine this. This commit changes the service type to
notify. This requires that Elasticsearch sends a notification message
via libsystemd sd_notify method. This commit does that by using JNA to
invoke this native method. Additionally, we use this integration to also
notify systemd when we are stopping.

The `elasticsearch-node override-version` command fails if it cannot read the
existing node metadata file. However, it reads this file strictly and fails if
there are any unknown fields, which means it will not be useful if we add
another field in future.
This commit adds leniency to this command, allowing it to ignore any unknown
fields and proceed with the downgrade. A downgrade is already unsafe, and the
user is already copiously warned about this, so being lenient in this case does
not make things much worse.
Today when creating an index and checking cluster shard limits, we check
the number of shards before applying index templates. At this point, we
do not know the actual number of shards that will be used to create the
index. In a case when the defaults are used and a template would
override, we could be grossly underestimating the number of shards that
would be created, and thus incorrectly applying the limits. This commit
addresses this by checking the shard limits after applying index
templates.
We often start testing with early access versions of new Java
versions and this have caused minor issues in our tests
(i.e. #43141) because the version string that the JVM reports
cannot be parsed as it ends with the string -ea.
This commit changes how we parse and compare Java versions to
allow correct parsing and comparison of the output of java.version
system property that might include an additional alphanumeric
part after the version numbers
(see [JEP 223[(https://openjdk.java.net/jeps/223)). In short it
handles a version number part, like before, but additionally a
PRE part that matches ([a-zA-Z0-9]+).
It also changes a number of tests that would attempt to parse
java.specification.version in order to get the full version
of Java. java.specification.version only contains the major
version and is thus inappropriate when trying to compare against
a version that might contain a minor, patch or an early access
part. We know parse java.version that can be consistently
parsed.

{"important" :"phrase match", "less_important": "nothing important"}
{ "index" : {"_id" : "2" } }
{"important" :"nothing important", "less_important" :"phrase match"}
Produces the expected scores: 13.8 for doc1, and 1.38 for doc2
indexing:
{ "index" : {"_id" : "1" } }

{ "index" : {"_id" : "2" } }
{"important" :"nothing important", "less_important" :"phrase match"}
{ "index" : {"_id" : "3" } }
{"important" :"phrase match", "less_important": "nothing important"}
Produces scores: 9.4 for doc1, and 1.96 for doc2 which are found in the
error logs.

Fields in JSON logs should be an escaped JSON fields. It is a broken json value at the moment
"stats": "["group1", "group2"]", -> "stats": "[\"group1\", \"group2\"]",
This should later be refactored into a JSON array of strings (the same as types in 7.x)
Today we block access to the pending tasks API before the cluster has recovered
its state. There's no real need to do so, and the master does meaningful work
even before performing state recovery so it might sometimes be useful to allow
access to this API. This commit changes this API to ignore all cluster blocks.
Fixes#44652
The field has to be defined in log4j2.properties and should be an
escaped JSON for now (it is a broken JSON at the moment). This should later be refactored into a JSON array
of strings.
Deprecation logger was filtering log entries by key, that means that if two log messages with the same key are logged from different users, then the second log messages will be filtered.
This change allows to log deprecation message with the same key by different users.

* It seems redundant to synchronize here and check that the map hasn't checked via the `isRunning` under the mutex
* The map won't change if under the mutex that locks on all the updates to it
* Without the mutex it's very unlikely to change inside the method call relative to the likelihood of changing until the generic pool where we check for `isRunning` again anyway
-> just remove the synchronization (it's on the IO loop) and check since we do check the running state on the generic pool under the mutex anyway when we actually fail it
We have to copy the field names otherwise we either have a handle of a
list that a caller might mutate or we might mutate when they aren't
expecting it, or worse, a handle of a list that is not mutable (and we
end up mutating the list).

* We only had the `size == 0` optimization in some but not all spots of deserializing collections in this class, fixed the remaining spots.
* Also fixed the a similar spot when deserializing `ThreadContextStruct` that could now be simplified (it was apparently doing it's own version of this optimization for the first map it deserialized before ... but not for the second map -> made it not instantiate anything if both maps are empty since it's always the same object here anyway)
* Optimize some StreamOutput Operations
* Writing numbers byte by byte adds a lot of unnecessary bounds checks to serialization
* Serializing to a threadlocal `byte[]` instead and bulk writing gives about a 50% speedup on `long` and `vlong` (for large numbers) writes and 30% for `int`, `vint` on Linux on an i9
* Using a threadlocal of the maximum string buffer size we used to allocate before also removes allocations when writing strings in general since we now never have to allocate a `byte[]` for that
* And don't have to GC one either resolving the TODO removed here
This commit converts all remaining TransportRequest and
TransportResponse classes to implement Writeable, and disallows
Streamable implementations.

NamedAnalyzer should return the same AnalysisMode than any custom analyzer it
wraps, otherwise AnalysisMode.ALL. This used to be only CustomAnalyzer in the
past, but with the introduction of the ReloadableCustomAnalyzer this needs to be
added as an option where the analysis mode gets propagated.

This commit removes support for the translog checkpoint format from versions
before 6.0.0 since 7.x versions are incompatible with indices from these
versions.

By mistake in 7.x types field was removed from slow logs. Types are
still present in that version, so this have to be present as a JSON
field

This commit converts several utility classes that implement Streamable
to have StreamInput constructors. It also adds a default version of
readFrom to Streamable so that overriding to throw UOE is not necessary.

This commit converts several more classes from streamable to writeable
in server, mostly within the o.e.index and o.e.persistent packages.

This commit converts subclasses of ShardOperationFailedException to
implement ctors with StreamInput instead of readFrom. It also simplifies
IndicesShardStoresResponse.Failure to serialize its shardId after the
super data.
