When a primary is relocated from an old node to a new node, it can have
ops in its translog that do not have a sequence number assigned. When a
file-based recovery is started, this can lead to skipping these ops when
replaying the translog due to a bug in the recovery logic. This commit
addresses this bug and adds a test in the BWC tests.

Currently, update action internally uses deprecated index and delete
transport actions. As of #21964, these tranport actions were deprecated
in favour of using single item bulk request. In this commit, update action
uses single item bulk action.
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.
The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.
As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.
In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.

GeoDistance query, sort, and scripts make use of a crazy GeoDistance enum for handling 4 different ways of computing geo distance: SLOPPY_ARC, ARC, FACTOR, and PLANE.

The test tried to create a situation where a stale replica is the only shard available. It did so by stopping the node with the replica, indexing some, stopping the primary node, starting a new node. This is flawed because the newly started node may reuse the data path of the primary node and things go back to green. Instead we should make sure that the replica is on the path that will be selected when the new node is started (i.e., the path with the smaller ordinal)
This commit adds a BytesRestResponse.errorFromXContent() method to parse the error returned by BytesRestResponse. It returns a ElasticsearchStatusException instance.
Currently, if a previously allocated shard has no in-sync copy in the
cluster, but there is a stale replica copy, the explain API does not
include information about the stale replica copies in its output. This
commit includes any shard copy information available (even for stale
copies) when explaining an unassigned primary shard that was previously
allocated in the cluster.
This situation can arise as follows: imagine an index with 1 primary and
1 replica and a cluster with 2 nodes. If the node holding the replica
is shut down, and data continues to be indexed, only the primary will
have the latest data and the replica that has gone offline will be
marked as stale. Now, suppose the node holding the primary is shut
down. There are no copies of the shard data in the cluster. Now, start
the first stopped node (holding the stale replica) back up. The cluster
is red because there is no in-sync copy available. Running the explain
API before would inform the user that there is no valid shard copy in
the cluster for that shard, but it would not provide any information
about the existence of the stale replica that exists on the restarted
node. With this commit, the explain API provides information about all
the stale replica copies when explaining the unassigned primary.
Currently, stored scripts use a namespace of (lang, id) to be put, get, deleted, and executed. This is not necessary since the lang is stored with the stored script. A user should only have to specify an id to use a stored script. This change makes that possible while keeping backwards compatibility with the previous namespace of (lang, id). Anywhere the previous namespace is used will log deprecation warnings.
The new behavior is the following:
When a user specifies a stored script, that script will be stored under both the new namespace and old namespace.
Take for example script 'A' with lang 'L0' and data 'D0'. If we add script 'A' to the empty set, the scripts map will be ["A" -- D0, "A#L0" -- D0]. If a script 'A' with lang 'L1' and data 'D1' is then added, the scripts map will be ["A" -- D1, "A#L1" -- D1, "A#L0" -- D0].
When a user deletes a stored script, that script will be deleted from both the new namespace (if it exists) and the old namespace.
Take for example a scripts map with {"A" -- D1, "A#L1" -- D1, "A#L0" -- D0}. If a script is removed specified by an id 'A' and lang null then the scripts map will be {"A#L0" -- D0}. To remove the final script, the deprecated namespace must be used, so an id 'A' and lang 'L0' would need to be specified.
When a user gets/executes a stored script, if the new namespace is used then the script will be retrieved/executed using only 'id', and if the old namespace is used then the script will be retrieved/executed using 'id' and 'lang'
The seq# base recovery logic relies on rolling back lucene to remove any operations above the global checkpoint. This part of the plan is not implemented yet but have to have these guarantees. Instead we should make the seq# logic validate that the last commit point (and the only one we have) maintains the invariant and if not, fall back to file based recovery.
This commit adds a test that creates situation where rollback is needed (primary failover with ops in flight) and fixes another issue that was surfaced by it - if a primary can't serve a seq# based recovery request and does a file copy, it still used the incoming `startSeqNo` as a filter.

With the new secure settings, methods like getAsMap() no longer work
correctly as a means of checking for empty settings, or the total size.
This change converts the existing uses of that method to use methods
directly on Settings. Note this does not update the implementations to
account for SecureSettings, as that will require a followup which
changes how secure settings work.
* Integrate UnifiedHighlighter
This change integrates the Lucene highlighter called "unified" in the list of supported highlighters for ES.
This highlighter can extract offsets from either postings, term vectors, or via re-analyzing text.
The best strategy is picked automatically at query time and depends on the field and the query to highlight.
In #22762, settings preparation during bootstrap was changed slightly to
account for SecureSettings, by starting with a fresh settings builder
after reading the initial configuration. However, this the defaults from
system properties were never re-read. This change fixes that bug (which
was never released).
closes#22861
Usually the order in which we serialize sets and maps of things doesn't matter,
but since InnerHitBuilder is part of SearchSourceBuilder, which is in turn used
as a cache key in its bytes serialization, we need to ensure the order of all
these fields when writing them to an output stream.
This adds tests and makes sure we iterate over the scriptField set and the
childInnerHits map in a fixed order.

This moves the building blocks for delete by query into core. This
should enabled two thigns:
1. Plugins other than reindex to implement "bulk by scroll" style
operations.
2. Plugins to directly call delete by query. Those plugins should
be careful to make sure that task cancellation still works, but
this should be possible.
Notes:
1. I've mostly just moved classes and moved around tests methods.
2. I haven't been super careful about cohesion between these core
classes and reindex. They are quite interconnected because I wanted
to make the change as mechanical as possible.

This commit introduces sequence-number-based recovery. When a replica
has fallen out of sync, rather than performing a file-based recovery we
first attempt to replay operations since the last local checkpoint on
the replica. To do this, at the start of recovery the replica tells the
primary what its local checkpoint is. The primary will then wait for all
operations between that local checkpoint and the current maximum
sequence number to complete; this is to ensure that there are no gaps in
the operations that will be replayed from the primary to the
replica. This is a best-effort attempt as we currently have no
guarantees on the primary that these operations will be available; if we
are not able to replay all operations in the desired range, we just
fallback to file-based recovery. Later work will strengthen the
guarantees.

At this point AbstractSearchAsyncAction is just a base-class for the first phase of a search where we have multiple replicas
for each shardID. If one of them is not available we move to the next one. Yet, once we passed that first stage we have to work with
the shards we succeeded on the initial phase.
Unfortunately, subsequent phases are not fully detached from the initial phase since they are all non-static inner classes.
In future changes this will be changed to detach the inner classes to test them in isolation and to simplify their creation.
The AbstractSearchAsyncAction should be final and it should just get a factory for the next phase instead of requiring subclasses
etc.
This commit adds a ElasticsearchException.failureFromXContent() that can be used to parse the result of ElasticsearchException.generateFailureXContent().
Today we cache query results even if the query timed out. This is obviously
problematic since results are not complete. Yet, the decision if a query timed
out or not happens too late to simply not cache the result since if we'd just throw
an exception all currently waiting requests with the same request / cache key would
fail with the same exception without the option to access the result or to re-execute.
Instead, this change will allow the request to enter the cache but invalidates it immediately.
Concurrent request might not get executed and return the timed out result which is not absolutely
correct but very likely since identical requests will likely timeout as well. As a side-effect
we won't hammer the node with concurrent slow searches but rather only execute one of them
and return shortly cached result.
Closes#22789
The output of the ElasticsearchException.generateThrowableXContent() method can be parsed back by the ElasticsearchException.fromXContent() method.
This commit adds unit tests in the style of the to-and-from-xcontent tests we already have for other parsing methods. It also relax the strict parsing of the ElasticsearchException.fromXContent() so that it does not throw an exception when custom metadata and headers are parsed, as long as they are either strings or arrays of strings. Every other type is ignored at parsing time.
Some tests verify that all connection have been closed but due to the
async / concurrent nature of `RemoteClusterConnection` there are situations
where we notify listeners that trigger tests to finish before we actually
closed all connections. The race is very very small and has no impact on the
code correctness. This commit documents and improves the way we close
connections to ensure test won't fail with false positives.
Closes#22803
This commit removes the search type `dfs_query_and_fetch` without a
replacement. We don't allow to use this type via REST since 2.x
but still keep it around for no particular reason. There we no users

codebase. `query_and_fetch` is still used internally to safe a roundtrip
if there is only one shard but it can't be used via the rest interface.

Previous to his change when the range query was rewritten to an unbounded range (`[* TO *]`) it maintained the timezone and format for the query. This means that queries with different timezones and format which are rewritten to unbounded range queries actually end up as different entries in the search request cache.
This is inefficient and unnecessary so this change nulls the timezone and format in the rewritten query so that regardless of the timezone or format the rewritten query will be the same.
Although this does not fix#22412 (since it deals with the WITHIN case rather than the INTERSECTS case) it is born from the same arguments

* Add top hits collapsing to search request
The field collapsing is done with a custom top docs collector that "collapse" search hits with same field value.
The distributed aspect is resolve using the two passes that the regular search uses. The first pass "collapse" the top hits, then the coordinating node merge/collapse the top hits from each shard.
```
GET _search
{
"collapse": {
"field": "category",
}
}
```
This change also adds an ExpandCollapseSearchResponseListener that intercepts the search response and expands collapsed hits using the CollapseBuilder#innerHit} options.
The retrieval of each inner_hits is done by sending a query to all shards filtered by the collapse key.
```
GET _search
{
"collapse": {
"field": "category",
"inner_hits": {
"size": 2
}
}
}
```
To effectively allow a plugin to intercept a transport handler it needs
to know if the handler must be executed even if there is a rejection on the
thread pool in the case the wrapper forks a thread to execute the actual handler.
This commit adds a SpecialPermission constant and uses that constant
opposed to introducing new instances everywhere.
Additionally, this commit introduces a single static method to check that
the current code has permission. This avoids all the duplicated access

There are presently 7 ctor args used in any rest handlers:
* `Settings`: Every handler uses it to initialize a logger and
some other strange things.
* `RestController`: Every handler registers itself with it.
* `ClusterSettings`: Used by `RestClusterGetSettingsAction` to
render the default values for cluster settings.
* `IndexScopedSettings`: Used by `RestGetSettingsAction` to get
the default values for index settings.
* `SettingsFilter`: Used by a few handlers to filter returned
settings so we don't expose stuff like passwords.
* `IndexNameExpressionResolver`: Used by `_cat/indices` to
filter the list of indices.
* `Supplier<DiscoveryNodes>`: Used to fill enrich the response
by handlers that list tasks.
We probably want to reduce these arguments over time but
switching construction away from guice gives us tighter
control over the list of available arguments.
These parameters are passed to plugins using
`ActionPlugin#initRestHandlers` which is expected to build and
return that handlers immediately. This felt simpler than
returning an reference to the ctors given all the different
possible args.
Breaks java plugins by moving rest handlers off of guice.
Today we try to be smart and make a generic decision if an exception should
be treated as a document failure but in some cases concurrency in the index writer
make this decision very difficult since we don't have a consistent state in the case
another thread is currently failing the IndexWriter/InternalEngine due to a tragic event.
This change simplifies the exception handling and makes specific decisions about document failures
rather than using a generic heuristic. This prevent exceptions to be treated as document failures
that should have failed the engine but backed out of failing since since some other thread has
already taken over the failure procedure but didn't finish yet.
Similar to the Filters aggregation but only supports "keyed" filter buckets and automatically "ANDs" pairs of filters to produce a form of adjacency matrix.

This commit fixes an issue with deprecation logging for lenient
booleans. The underlying issue is that adding deprecation logging for
lenient booleans added a static deprecation logger to the Settings
class. However, the Settings class is initialized very early and in CLI
tools can be initialized before logging is initialized. This leads to
status logger error messages. Additionally, the deprecation logging for
a lot of the settings does not provide useful context (for example, in
the token filter factories, the deprecation logging only produces the
name of the setting, but gives no context which token filter factory it
comes from). This commit addresses both of these issues by changing the
call sites to push a deprecation logger through to the lenient boolean
parsing.

* Fix NPE on FieldStats with mixed cluster on version pre/post 5.2
In 5.2 the FieldStats API can return null min/max values.
These values cannot be deserialized by a node with version pre 5.2 so if this node
is pick to coordinate a FieldStats request in a mixed cluster an NPE can be thrown.
This change prevents the NPE by removing the non serializable FieldStats object directly in the field stats shard request.
The filtered fields will not be present in the response when a node pre 5.2 acts as a coordinating node.

testAckedIndexing now waits for all nodes to stabilize in the cluster

Today we do not preserve response headers if they are present on a transport protocol
response. While preserving these headers is not always desired, in the most cases we

ie. on the coordinating node such that this bug wasn't uncovered until #22647

This change makes it possible for custom routing values to go to a subset of shards rather than
just a single shard. This enables the ability to utilize the spatial locality that custom routing can
provide while mitigating the likelihood of ending up with an imbalanced cluster or suffering
from a hot shard.
This is ideal for large multi-tenant indices with custom routing that suffer from one or both of
the following:
- The big tenants cannot fit into a single shard or there is so many of them that they will likely
end up on the same shard
- Tenants often have a surge in write traffic and a single shard cannot process it fast enough
Beyond that, this should also be useful for use cases where most queries are done under the context
of a specific field (e.g. a category) since it gives a hint at how the data can be stored to minimize
the number of shards to check per query. While a similar solution can be achieved with multiple
concrete indices or aliases per value today, those approaches breakdown for high cardinality fields.
A partitioned index enforces that mappings have routing required, that the partition size does not
change when shrinking an index (the partitions will shrink proportionally), and rejects mappings
that have parent/child relationships.
Closes#21585
Instead of forcing each task to register all nodes where its children are running, this commit runs cancellation on all nodes. The task cancellation operation doesn't run too frequently, so this optimization doesn't seem to be worth additional complexity of the interface.
Previously, certain settings that could take multiple comma delimited
values would pick up incorrect values for all entries but the first if
each comma separated value was followed by a whitespace character. For
example, the multi-value "A,B,C" would be correctly parsed as
["A", "B", "C"] but the multi-value "A, B, C" would be incorrectly parsed
as ["A", " B", " C"].
This commit allows a comma separated list to have whitespace characters
after each entry. The specific settings that were affected by this are:
cluster.routing.allocation.awareness.attributes
index.routing.allocation.require.*
index.routing.allocation.include.*
index.routing.allocation.exclude.*

This commit tries to simplify the way ElasticsearchException are rendered to xcontent. It adds some documentation and renames and merges some methods. Current behavior is preserved, the goal is to be more readable and centralize everything in the ElasticsearchException class.
`EngineClosedException` is a ES level exception that is used to indicate that the engine is closed when operation starts. It doesn't really add much value and we can use `AlreadyClosedException` from Lucene (which may already bubble if things go wrong during operations). Having two exception can just add confusion and lead to bugs, like wrong handling of `EngineClosedException` when dealing with document level failures. The latter was exposed by `IndexWithShadowReplicasIT`.
This PR also removes the AwaitFix from the `IndexWithShadowReplicasIT` tests (which was what cause this to be discovered). While debugging the source of the issue I found some mismatches in document uid management in the tests. The term that was passed to the engine didn't correspond to the uid in the parsed doc - those are fixed as well.
Today we have quite some abstractions that are essentially providing a simple

Currently both ProfileResult and CollectorResult print the time field in a human readable string format
(e.g. "time": "55.20315000ms"). When trying to parse this back to a long value, for example to use in
the planned high level java rest client, we can lose precision because of conversion and rounding issues.
This change adds a new additional field (`time_in_nanos`) to the profile response to be able to get the
original time value in nanoseconds back.
The old `time` field is only printed when the `?`human=true` flag in the url is set. This follow the behaviour for
all other stats-related apis. Also the format of the `time` field is slightly changed. Instead of always formatting
the output as a 10-digit ms value, by using the `XContentBuilder#timeValueField()` method we now print
the largest time unit present is used (e.g. "s", "ms", "micros").
An operation that completed successfully on a primary can result in a
version conflict on a replica due to the asynchronous nature of
operations. When a replica operation results in a version conflict, the
operation is not added to the translog. This leads to gaps in the
translog which is problematic as it can lead to situations where a
replica shard can never advance its local checkpoint. As such operations
are just normal course of business for a replica shard, these operations
should be treated as if they completed successfully. This commit adds
these operations to the translog.

For certain situations, end-users need the base path for Elasticsearch
logs. Exposing this as a property is better than hard-coding the path
into the logging configuration file as otherwise the logging
configuration file could easily diverge from the Elasticsearch
configuration file. Additionally, Elasticsearch will only have
permissions to write to the log directory configured in the
Elasticsearch configuration file. This commit adds a property that
exposes this base path.
One use-case for this is configuring a rollover strategy to retain logs
for a certain period of time. As such, we add an example of this to the
documentation.
Additionally, we expose the property es.logs.cluster_name as this is
used as the name of the log files in the default configuration.
Finally, we expose es.logs.node_name in cases where node.name is
explicitly set in case users want to include the node name as part of
the name of the log files.

Deleting indices is an important event in a cluster and as such should
be logged at the info level. This commit changes the logging level on
index deletion to the info level.
Relates #22627
We have made the security manager non-optional, but the Javadocs for
Security.java imply that it still is. This commit fixes this issue.
Relates #16176
ClusterService and TransportService expect the local discovery node to be set
before they are started but this requires manual interaction and is error prone since
to work absolutely correct they should share the same instance (same ephemeral ID).
TransportService also has 2 modes of operation, mainly realted to transport client vs. internal
to a node. This change removes the mode where we don't maintain a local node and uses a dummy local
node in the transport client since we don't bind to any port in such a case.
Local discovery node instances are now managed by the node itself and only suppliers and factories that allow
creation only once are passed to TransportService and ClusterService.
There was still small race in MockTcpTransport where channesl that are concurrently
closing are not yet removed from the reference tracking causing tests to fail. Compared to
the other races before this is a rather small windown and requires very very short test durations.

Today there are several races / holes in TcpTransport and MockTcpTransport
that can allow connections to be opened and remain unclosed while the actual
transport implementation is closed. A recently added assertions in #22554 exposes
these problems. This commit fixes several issues related to missed locks or channel
creations outside of a lock not checking if the resource is still open.
This change disables the _all meta field by default.
Now that we have the "all-fields" method of query execution, we can save both
indexing time and disk space by disabling it.
_all can no longer be configured for indices created after 6.0.

TcpTransport has an actual mechanism to stop resources in subclasses.
Instead of overriding `doStop` subclasses should override `stopInternal`
that is executed under the connection lock guaranteeing that there is no
concurrency etc.

* Settings: Make s3 repository sensitive settings use secure settings
This change converts repository-s3 to use the new secure settings. In
order to support the multiple ways we allow aws creds to be configured,
it also moves the main methods for the keystore wrapper into a
SecureSettings interface, in order to allow settings prefixing to work.
* Fix Translog.Delete serialization for sequence numbers
Translog.Delete used `.writeVLong` instead of `.writeLong` for the sequence
number and primary term (and their respective "read" variants). This could lead
to issues where a 5.x node sent a translog operation with a negative sequence
number (-2 for unassigned seq no) that tripped an assertion serializing a
negative number and causing ES to exit.
Adds a unit test for serialization and a mixed-cluster REST test, since that was
how this was originally caught.
* Use more realistic values for random seqNum and primary term
* Add comment with TODO for removal in 7.0
* Change comment into an assert
The low level TCP handshake can cause channel / connection leaks if it's interrupted
since the caller doesn't close the channel / connection if the handshake was not successful.
This commit fixes the channel leak and adds general test infrastructure to detect channel leaks
in the future.
