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. Only two of these are necessary: ARC, PLANE. This commit removes SLOPPY_ARC, and FACTOR and cleans up the way Geo distance is computed.
In 5.2 we stopped sending the source parameter if the user didn't
specify it. This was a mistake as versions before 2.0 look like
they don't always include the `_source`. This is because reindex
requests some metadata fields. Anyway, now we say `"_source": true`
if there isn't a `_source` configured in the reindex request.
Closes#22893
This commit change ElasticsearchException.failureFromXContent() method so that it now parses root causes which were ignored before, and adds them as suppressed exceptions of the returned exception.
We were incorrectly resolving qualified method references at run
time when invoked on `def`. This lead to errors like
`The struct with name [org] has not been defined.` when attempting
```
doc.date.dates.stream().map(
org.joda.time.ReadableDateTime::centuryOfEra
).collect(Collectors.toList())
```
Implemented by wrapping an array of reused `ModuleDateTime`s that
we grow when needed. The `ModuleDateTime`s are reused when we
move to the next document.
Also improves the error message returned when attempting to modify
the `ScriptdocValues`, removes a couple of allocations, and documents
that the date functions are available in Painless.

This disallows object mappings that would accidentally create something like
`foo..bar`, which is then unparsable for the `bar` field as it does not know
what its parent is.
Resolves#22794
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.
Added missing CONSOLE scripts to documentation for sampler and diversified_sampler aggs.
Includes new StackOverflow index setup in build.gradle
Closes#22746
* Formatting tweaks
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
This change removes the ability to set region for s3 repositories.
Endpoint should be used instead if a custom s3 location needs to be
used.
closes#22758
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.
Closes#22808
Follow up of #22857 where we deprecate automatic creation of azure containers.
BTW I found that the `AzureSnapshotRestoreServiceIntegTests` does not bring any value because it runs basically a Snapshot/Restore operation on local files which we already test in core.
So instead of trying to fix it to make it pass with this PR, I simply removed it.
