Enable avoiding mmap bootstrap check (#32421)
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.

Use a dedicated ConnectionManger for RemoteClusterConnection (#32988)
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

Protect scheduler engine against throwing listeners (#32998)
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.

Trim translog when safe commit advanced (#32967)
Since #28140 when the global checkpoint is advanced, we try to move the
safe commit forward, and clean up old index commits if possible. However,

This change makes sure that we prune both old translog and index commits
when the safe commit advanced.

Logging: Use settings when building daemon threads (#32751)
Subclasses of `EsIntegTestCase` run multiple Elasticsearch nodes in the
same JVM and when we log we look at the name of the thread to figure out
the node name. This makes sure that all calls to `daemonThreadFactory`
include the node name.

Closes #32574

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
this and I'd like to get these log lines fixed up sooner rather than
later.

All Translog inner closes should happen after tragedy exception is set (#32674)
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.

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.

Move connection listener to ConnectionManager (#32956)
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.

NETWORKING: Make RemoteClusterConn. Lazy Resolve DNS (#32764)
* Lazy resolve DNS (i.e. `String` to `DiscoveryNode`) to not run into indefinitely caching lookup issues (provided the JVM dns cache is configured correctly as explained in https://www.elastic.co/guide/en/elasticsearch/reference/6.3/networkaddress-cache-ttl.html)
   * Changed `InetAddress` type to `String` for that higher up the stack
   * Passed down `Supplier<DiscoveryNode>` instead of outright `DiscoveryNode` from `RemoteClusterAware#buildRemoteClustersSeeds` on to lazy resolve DNS when the `DiscoveryNode` is actually used (could've also passed down the value of `clusterName = REMOTE_CLUSTERS_SEEDS.getNamespace(concreteSetting)` together with the `List<String>` of hosts, but this route seemed to introduce less duplication and resulted in a significantly smaller changeset).

Make Geo Context Mapping Parsing More Strict (#32821)
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.

Jonathan Little a08127c072 Scripted metric aggregations: add deprecation warning and system property to control legacy params (#31597)
* Scripted metric aggregations: add deprecation warning and system property to control legacy params

Scripted metric aggregation params._agg/_aggs are replaced by state/states context variables. By default the old params are still present, and a deprecation warning is emitted when Scripted Metric Aggregations are used. A new system property can be used to disable the legacy params. This functionality will be removed in a future revision.

* Fix minor style issue and docs test failure

* Disable deprecated params._agg/_aggs in tests and revise tests to use state/states instead

* Add integration test covering deprecated scripted metrics aggs params._agg/_aggs access

* Disable deprecated params._agg/_aggs in docs integration tests and revise stored scripts to use state/states instead

* Revert unnecessary migrations doc change

A relevant note should be added in the changes destined for 7.0; this PR is going to be backported to 6.x.

* Replace deprecated _agg param bwc integration test with a couple of unit tests

* Fix compatibility test after merge

* Rename backwards compatibility system property per code review feedback

* Tweak deprecation warning text per review feedback

Remove assertion in testDocStats on deletedDocs counter (#32914)
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.

Move CharArrays to core lib (#32851)
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 test reproducability in AbstractBuilderTestCase setup (#32403)
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.

Refactor TransportShardBulkAction to better support retries (#31821)
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.

lipsill be54ba39c4 Add expected mapping type to `MapperException` (#31564)
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.

Fixes suggestion generics (#32706)
* 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`

Prevent cause from being null in ShardOperationFailedException (#32640)
`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.

Preserve index_uuid when creating QueryShardException (#32677)
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.

serialize suggestion responses as named writeables (#30284)
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.

Expose whether or not the global checkpoint updated (#32659)
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.

Verify primary mode usage with assertions (#32667)
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.

Cross-cluster search: preserve cluster alias in shard failures (#32608)
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.

Fix race between replica reset and primary promotion (#32442)
We've recently seen a number of test failures that tripped an assertion in IndexShard (see issues
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.

Logging: Make node name consistent in logger (#31588)
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.

High-level client: fix clusterAlias parsing in SearchHit (#32465)
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.

update rollover to leverage write-alias semantics (#32216)
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

Do not expose hard-deleted docs in Lucene history (#32333)
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.

IndicesClusterStateService should replace an init. replica with an init. primary with the same aId (#32374)
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.

Validate source of an index in LuceneChangesSnapshot (#32288)
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.

Introduce index store plugins (#32375)
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.

Make sure _forcemerge respects `max_num_segments`. (#32291)
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.

Tim Vernum 387c3c7f1d Introduce Application Privileges with support for Kibana RBAC (#32309)
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

Add WeightedAvg metric aggregation (#31037)
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

easy this test breaks. Also the current assertions doesn't add a lot in terms of catching

Fix multi level nested sort (#32204)
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 (#32056)
* 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

Nhat Nguyen fe574f89f8 CCR: Translog op on primary should have versionType
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.

Remove aliases resolution limitations when security is enabled (#31952)
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.

A replica can be promoted and started in one cluster state update (#32042)
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.

Fix `range` queries on `_type` field for singe type indices (#31756)
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.

Enable testing in FIPS140 JVM (#31666)
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

Fix put mappings java API documentation (#31955)
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.

Daniel Mitterdorfer 1fef139c11 Ensure only parent breaker trips in unit test
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.

Colin Goodheart-Smithe 0edb096eb4 Adds a new auto-interval date histogram (#28993)
* 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.

Closes #9572

* Adds ability to merge within a rounding

* Fixes nonn-timezone doc test failure

* Fix time zone tests

* iterates on tests

* Adds test case and documentation changes

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

* Changes to only do complex reduction on final reduce

* merge latest with master

* correct tests and add a new test case for 10k buckets

* refactor to perform bucket number check in innerBuild

* correctly derive bucket setting, update tests to increase bucket threshold

* fix checkstyle

* address code review comments

* add documentation for default buckets

Circuit-break based on real memory usage
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.

Force execution of fetch tasks (#31974)
Forces fetch tasks to queue even in the event that the queue is
already full. The reasoning is that fetch tasks may only be follow-up
to query tasks, so the number of additional fetch tasks that may enter
the threadpool is expected to be reasonable.

Closes #29442

Tests: Fix SearchFieldsIT.testDocValueFields (#31995)
This test produced different implementations of joda time classes,
depending on if the data was serialized or not (DateTime vs
MutableDateTime). This now uses a common base class to extract the
milliseconds from the data.

Revert translog changes introduced for CCR (#31947)
We introduced these changes in #26708 because for CCR.
However, CCR now uses Lucene instead of translog.

This commit reverts these changes so that we can
minimize differences between the ccr and the master branch.

Rewrite shard follow node task logic (#31581)
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.

Fix broken NaN check in MovingFunctions#stdDev() (#31888)
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.

Date: Add DateFormatters class that uses java.time (#31856)
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.

Change trappy float comparison (#31889)
Comparing primitive floats with '==' can be trappy because e.g. special handling
of NaN values. It can be avoided by using Float.compare().

add support for is_write_index in put-alias body parsing (#31674)
* add support for is_write_index in put-alias body parsing

The Rest Put-Alias Action does separate parsing of the alias body
to construct the IndicesAliasesRequest. This extra parsing
was missed in #30703.

* test flag was not just ignored by the parser

* disable backcompat tests
