This change copies and validates the soft-deletes setting during resize.
If the source enables soft-deletes, the target must also enable it.

Today the FilterRoutingTests take the belt-and-braces approach of excluding
some node attribute values and including some others. This means that we don't
really test that both inclusion and exclusion work correctly: as long as one of
them works as expected then the test will pass. This change improves these
tests by only using one approach at once, demonstrating that both do indeed
work, and adds tests for various other scenarios too.
In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
This commit ensures that we bootstrap a new history_uuid when force
allocating a stale primary. A stale primary should never be the source
of an operation-based recovery to another shard which exists before the
forced-allocation.

* CompoundProcessor is in the ingest package now

Today when checking settings dependencies, we do not check if fallback
settings are present. This means, for example, that if
cluster.remote.*.seeds falls back to search.remote.*.seeds, and
cluster.remote.*.skip_unavailable and search.remote.*.skip_unavailable
depend on cluster.remote.*.seeds, and we have set search.remote.*.seeds
and search.remote.*.skip_unavailable, then validation will fail because
it is expected that cluster.ermote.*.seeds is set here. This commit
addresses this by also checking fallback settings when validating
dependencies. To do this, we adjust the settings exist method to also
check for fallback settings, a case that it was not handling previously.
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.
We invoke force merge twice in the test to verify that recovery sources
are pruned when the global checkpoint advanced. However, if the global
checkpoint equals to the local checkpoint in the first force-merge, the
second force-merge will be a noop because all deleted docs are expunged
in the first merge already. We need to flush a new segment to make merge
happen so we can verify that all recovery sources are pruned.
Instead of passing DirectoryService which causes yet another dependency
on Store we can just pass in a Directory since we will just call
`DirectoryService#newDirectory()` on it anyway.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.

When we rollover and index we write the conditions of the rollover that
the old index met into the old index. Loading this index metadata
requires a working `NamedXContentRegistry` that has been populated with
parsers from the rollover infrastructure. We had a few loads that didn't
use a working `NamedXContentRegistry` and so would fail if they ever
encountered an index that had been rolled over. Here are the locations
of the loads and how I fixed them:
* IndexFolderUpgrader - removed entirely. It existed to support opening
indices made in Elasticsearch 2.x. Since we only need this change as far
back as 6.4.1 which will supports reading from indices created as far
back as 5.0.0 we should be good here.
* TransportNodesListGatewayStartedShards - wired the
`NamedXContentRegistry` into place.
* TransportNodesListShardStoreMetaData - wired the
`NamedXContentRegistry` into place.
* OldIndexUtils - removed entirely. It existed to support the zip based
index backwards compatibility tests which we've since replaced with code
that actually runs old versions of Elasticsearch.
In addition to fixing the actual problem I added full cluster restart
integration tests for rollover which would have caught this problem and
I added an extra assertion to IndexMetaData's deserialization code which
will trip if we try to deserialize and index's metadata without a fully
formed `NamedXContentRegistry`. It won't catch if use the *wrong*
`NamedXContentRegistry` but it is better than nothing.

With this commit we use the classic parent circuit breaker which does
not account for real memory usage. In those tests we want to have
reproducible results and hence it makes sense to disable the real memory
circuit breaker there.
Auto Following Patterns is a cross cluster replication feature that
keeps track whether in the leader cluster indices are being created with
names that match with a specific pattern and if so automatically let
the follower cluster follow these newly created indices.
This change adds an `AutoFollowCoordinator` component that is only active
on the elected master node. Periodically this component checks the
the cluster state of remote clusters if there new leader indices that
match with configured auto follow patterns that have been defined in
`AutoFollowMetadata` custom metadata.
This change also adds two new APIs to manage auto follow patterns. A put
auto follow pattern api:
```
PUT /_ccr/_autofollow/{{remote_cluster}}
{
"leader_index_pattern": ["logs-*", ...],
"follow_index_pattern": "{{leader_index}}-copy",
"max_concurrent_read_batches": 2
... // other optional parameters
}
```
and delete auto follow pattern api:
```
DELETE /_ccr/_autofollow/{{remote_cluster_alias}}
```
The auto follow patterns are directly tied to the remote cluster aliases
configured in the follow cluster.

With features like CCR building on the CCS infrastructure, the settings
prefix search.remote makes less sense as the namespace for these remote
cluster settings than does a more general namespace like
cluster.remote. This commit replaces these settings with cluster.remote
with a fallback to the deprecated settings search.remote.
There are two races in the testUpdateAndReadChangesConcurrently if the

Historically we have had a ESLoggingHandler in the netty module that
logs low-level connection operations. This class just extends the netty
logging handler with some (broken) message deserialization. This commit
fixes this message serialization and moves the class to server.
This new logger logs inbound and outbound messages. Eventually, we
should move other event logging to this class (connect, close, flush).
That way we will have consistent logging regards of which transport is
loaded.
Resolves#27306 on master. Older branches will need a different fix.
This commit is related to #32517. It allows an "server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. This functionality is only implemented for
the netty security transport.
This change adds an expert index setting called `index.merge.policy.deletes_pct_allowed`.
It controls the maximum percentage of deleted documents that is tolerated in the index.
Lower values make the index more space efficient at the expense of increased CPU and I/O activity.
Values must be between `20` and `50`. Default value is `33`.
Drops and unused logging constructor, simplifies a rarely used one, and
removes `Settings` from a third. There is now only a single logging ctor
that takes `Settings` and we'll remove that one in a follow up change.
The maximum number of fields per index is limited to 1000 by default by the
`index.mapping.total_fields.limit` setting to prevent accidental mapping
explosions due to too many fields. Currently all metadata fields also count
towards this limit, which can lead to some confusion when using lower limits.
It is not obvious for users that they cannot actually add as many fields as
are specified by the limit in this case.
This change takes the number of metadata fields out of the field count that we
check against the field limit. It also adds tests that check that we can add
fields up to the specified limit, but throw an exception for any additional field added.
Closes#24096
Deprecating a some setting specializations (e.g., list settings) does
not cause deprecation warning headers and deprecation log messages to
appear. This is due to a missed check for deprecation. This commit fixes
this for all setting specializations, and ensures that this can not be
missed again.
Adds a place for users to store cluster-wide data they wish to associate
with the cluster via the Cluster Settings API. This is strictly for
user-defined data, Elasticsearch makes no other other use of these
settings.
Now that types are unique per mapping we can retrieve the document mapper
without referencing the type. This fixes an NPE when stored fields are disabled.
For 6x we'll need a different fix since mappings can still have multiple types.
Relates #32941
This commit introduces the formal notion of a private setting. This
enables us to register some settings that we had previously not
registered as fully-fledged settings to avoid them being exposed via
APIs such as the create index API. For example, we had hacks in the
codebase to allow index.version.created to be passed around inside of
settings objects, but was not registered as a setting so that if a user
tried to use the setting on any API then they would get an
exception. This prevented users from setting index.version.created on
index creation, or updating it via the index settings API. By
introducing private settings, we can continue to reject these attempts,
yet now we can represent these settings as actual settings. In this
change, we register index.version.created as an actual setting. We do
not cutover all settings that we had been treating as private in this
pull request, it is already quite large due to moving some tests around
to account for the fact that some tests need to be able to set the
index.version.created. This can be done in a follow-up change.

We can have multiple documents in Lucene with the same seq_no for
parent-child documents (or without rollback). In this case, the usage
"lastSeenSeqNo + 1" is an off-by-one error as it may miss some
documents. This error merely affects the `skippedOperations` contract.

The existing implemention could not deal with negative numbers as well
as +- 999 milliseconds around the epoch.
This commit uses Instant.ofEpochMilli() and parses the input to
a number instead of using a date formatter.
This commit adds the support to early terminate the collection of a leaf
in the aggregation framework. This change introduces a MultiBucketCollector which
handles CollectionTerminatedException exactly like the Lucene MultiCollector.
Any aggregator can now throw a CollectionTerminatedException without stopping
the collection of a sibling aggregator. This is useful for aggregators that
can infer their result without visiting all documents (e.g.: a min/max aggregation on a match_all query).
Drops `Settings` from some logging ctors now that they are no longer
needed. This should allow us to stop passing `Settings` around to quite
as many places.

This PR removes the deprecated `Custom` class in `IndexMetaData`, in favor
of a `Map<String, DiffableStringMap>` that is used to store custom index
metadata. As part of this, there is now no way to set this metadata in a
template or create index request (since it's only set by plugins, or dedicated
REST endpoints).
The `Map<String, DiffableStringMap>` is intended to be a namespaced `Map<String,
String>` (`DiffableStringMap` implements `Map<String, String>`, so the signature
is more like `Map<String, Map<String, String>>`). This is so we can do things
like:
``` java
Map<String, String> ccrMeta = indexMetaData.getCustom("ccr");
```
And then have complete control over the metadata. This also means any
plugin/feature that uses this has to manage its own BWC, as the map is just
serialized as a map. It also means that if metadata is put in the map that isn't
used (for instance, if a plugin were removed), it causes no failures the way
an unregistered `Setting` would.
The reason I use a custom `DiffableStringMap` here rather than a plain
`Map<String, String>` is so the map can be diffed with previous cluster state
updates for serialization.
Supersedes #32683
We cut over to `index.resize.source.*` but still have these constants
being public in `IndexMetaData`. Those Settings and constants are not needed
in 7.x while we still need to keep the keys known to private settings since
they might be part of the index settings of old indices. We can remove that
in 8.0. Yet, we should remove the settings to make sure they are not used again.
Fix serialization of empty field capabilities response
When no response are required (no indices match the requested patterns) the
empty response throws an NPE in the transport serialization (writeTo).
If an exclude or an include clause removes an entry to a nested field in the original source at query time,
the creation of nested hits fails with an NPE. This change fixes this exception and replaces the nested document
source with an empty map.
Closes#33163Closes#33170
Today we add a NoOp to Lucene and translog if we fail to process an
indexing operation. However, we are only adding NoOps to translog for
delete operations. In order to have a complete history in Lucene, we
should add NoOps of failed delete operations to both Lucene and translog.

Today we support a static list of seed hosts in core Elasticsearch, and allow a
dynamic list of seed hosts to be provided via a file using the `discovery-file`
plugin. In fact the ability to provide a dynamic list of seed hosts is
increasingly useful, so this change moves this functionality to core
Elasticsearch to avoid the need for a plugin.
Furthermore, in order to start up nodes in integration tests we currently
assign a known port to each node before startup, which unfortunately sometimes
fails if another process grabs the selected port in the meantime. By moving the
`discovery-file` functionality into the core product we can use it to avoid
this race.
This change also moves the expected path to the file from
`$ES_PATH_CONF/discovery-file/unicast_hosts.txt` to
`$ES_PATH_CONF/unicast_hosts.txt`. An example of this file is not included in
distributions.
For BWC purposes the plugin still exists, but does nothing more than create the
example file in the old location, and issue a warning when it is used. We also
continue to support the old location for the file, but warn about its
deprecation.

The shrink action was renamed to `_resize` with the addition

always use the resize action.
We have had support for the `group_shard_failures` parameter in our code for a while, since we introduced failures grouping. When we introduced validation of parameters at REST, we seem to have forgotten to expose such parameter. Given that the parameter is effectively not supported for many months now, that no user has complained about that and that grouping is the expected behaviour, this commit removes support for the parameter.
`BucketUtils#suggestShardSideQueueSize` used to calculate the shard_size based on the number of shards. It returns now a different value only based on whether we are querying a single shard or multiple shards. This commit replaces the numberOfShards argument with a boolean that tells whether we are querying a single shard or not.
Exclude classes meant for newer versions than what we are auditing against, those classes won't be found. There's no reason to exclude JDK classes from newer versions, with this PR, we will not extract them in the first place.

Today a file-based recovery will replay all existing translog operations
from the primary on a replica so that that replica can have a full
history in translog as the primary. However, with soft-deletes enabled,
we should not do it because:
1. All operations before the local checkpoint of the safe commit exist in
the commit already.
2. The number of operations before the local checkpoint may be considerable
and requires a significant amount of time to replay on a replica.

The new implementation is functional equivalent with the old, ant based one.
It parses task standard error to get the missing classes and violations in the same way.
I considered re-using ForbiddenApisCliTask but Gradle makes it hard to build inheritance with tasks that have task actions , since the order of the task actions can't be controlled.
This inheritance isn't dully desired either as the third party audit task is much more opinionated and we don't want to expose some of the configuration.
We could probably extract a common base class without any task actions, but probably more trouble than it's worth.
Closes#31715
We generate slightly different NoOps in InternalEngine and
TransportShardBulkAction for the same failure.
1. InternalEngine uses Exception#getFailure to generate a message
without the class name: newOp [NoOp{seqNo=1, primaryTerm=1,
reason='Contexts are mandatory in context enabled completion field
[suggest_context]'}].
2. TransportShardBulkAction uses Exception#toString to generate a
message with the class name: NoOp{seqNo=1, primaryTerm=1,
reason='java.lang.IllegalArgumentException: Contexts are mandatory in
context enabled completion field [suggest_context]'}.
If a write operation fails while a replica is recovering, that replica
will possibly receive two different NoOps: one from recovery and one
from replication. These two different NoOps will trip
TranslogWriter#assertNoSeqNumberConflict assertion.
This commit ensures that we generate the same Noop for the same failure.
Closes#32986
As part of recent changes made to `ShardOperationFailedException` we introduced `index` and `shardId` members to the base class, but the subclasses are entirely responsible for the serialization of such fields. In the case of `ShardSearchFailure`, we have an additional `SearchShardTarget` instance member which also holds the index and the shardId, hence they get serialized as part of `SearchShardTarget` itself. When de-serializing a `ShardSearchFailure` though, we need to remember to also set the parent class `index` and `shardId` fields otherwise they get lost

The introduction of mapping version on index metadata has been
backported to 6.x. This commit adjusts the BWC version around mapping
version to account for this backport.
This commit introduces mapping version to index metadata. This value is
monotonically increasing and is updated on mapping updates. This will be
useful in cross-cluster replication so that we can request mapping
updates from the leader only when there is a mapping update as opposed
to the strategy we employ today which is to request a mapping update any
time there is an index metadata update. As index metadata updates can
occur for many reasons other than mapping updates, this leads to some
unnecessary requests and work in cross-cluster replication.
With this commit we implement a workaround for
https://bugs.openjdk.java.net/browse/JDK-8207200 which is a race
condition in the JVM that results in `IllegalArgumentException` to be
thrown in rare cases when we determine memory usage via `MemoryMXBean`.
As we do not want to fail requests in those cases we always return zero
memory usage.
