CRUD: Parsing changes for UpdateRequest (#29293)
Use `ObjectParser` to parse `UpdateRequest` so we reject unknown fields
and drop support for the `_fields` parameter because it was deprecated
in 5.x.
The default percentiles values and the default highlighter per- and
post-tags are currently publicly accessible and can be altered any time.
This change prevents this by restricting field access.
Today when reading an operation from the current generation fails
tragically we attempt to close the translog. However, by invoking close
before releasing the read lock we end up in self-deadlock because
closing tries to acquire the write lock and the read lock can not be
upgraded to a write lock. To avoid this, we move the close invocation
outside of the try-with-resources that acquired the read lock. As an
extra guard against this, we document the problem and add an assertion
that we are not trying to invoke close while holding the read lock.

test: Index more docs, so that it is less likely the search request does not time out.
This change adds a client that is connected to a remote cluster.
This allows plugins and internal structures to invoke actions on
remote clusters just like a if it's a local cluster. The remote
cluster must be configured via the cross cluster search infrastructure.
This adds 2 testcases that test if a shard goes idle
pending (uncommitted) segments are committed and unreferenced
files will be freed.

Control max size and count of warning headers
Add a static persistent cluster level setting
"http.max_warning_header_count" to control the maximum number of
warning headers in client HTTP responses.
Defaults to unbounded.
Add a static persistent cluster level setting
"http.max_warning_header_size" to control the maximum total size of
warning headers in client HTTP responses.
Defaults to unbounded.
With every warning header that exceeds these limits,
a message will be logged in the main ES log,
and any more warning headers for this response will be
ignored.
Unlike the `indices.create`, `indices.get_mapping` and `indices.put_mapping`
APIs, the index APIs do not need the `include_type_name` option, they can work
work with and without types withouth knowing whether types are being used.
Internally, `_doc` is used as a type if no type is provided, like for the
`indices.put_mapping` API.
This change adds the current primary term to the header of the current
translog file. Having a term in a translog header is a prerequisite step
that allows us to trim translog operations given the max valid seq# for
that term.
This commit also updates tests to conform the primary term invariant
which guarantees that all translog operations in a translog file have
its terms at most the term stored in the translog header.
Today we can use the soft-update feature from Lucene to maintain a
history of document. This change simply replaces hard-update in the
Engine by soft-update methods. Stale operations, delete, and no-ops will
be handled in subsequent changes. This change is just a cut-over from
hard-update to soft-update, no new functionality has been introduced.
This commit moves the `TimeValue` class into the elasticsearch-core project.
This allows us to use this class in many of our other projects without relying
on the entire `server` jar.

* Decouple TimeValue from Elasticsearch server classes
This commit decouples the `TimeValue` class from the other server classes. This
is in preperation to move `TimeValue` into the `elasticsearch-core` jar,
allowing us to use it from projects that cannot depend on the elasticsearch-core
library.

The skeleton of ElasticsearchMergePolicy is quite similar to
MergePolicyWrapper. This commit therefore makes ElasticsearchMergePolicy
inherited from MergePolicyWrapper instead of MergePolicy.
Currently, a flush stats contains only the total flush which is the sum
of manual flush (via API) and periodic flush (async triggered when the
uncommitted translog size is exceeded the flush threshold). Sometimes,
it's useful to know these two numbers independently. This commit tracks
and returns a periodic flush count in a flush stats.
This adds an `include_type_name` option to the `indices.create`,
`indices.get_mapping` and `indices.put_mapping` APIs, which defaults to `true`.
When set to `false`, then mappings will be returned directly in the body of
the `indices.get_mapping` API, without keying them by the type name, the
`indices.create` will expect mappings directly under the `mappings` key, and
the `indices.put_mapping` will use `_doc` as a type name and fail if a `type`
is provided explicitly.

Today we expose a mutable list of documents in ParseContext via
ParseContext#docs(). This, on the one hand places knowledge how
to access nested documnts in multiple places and on the other
allows for potential illegal access to nested only docs after
the docs are reversed. This change restricts the access and
streamlines nested / non-root doc access.
This change validates that the `_search` request does not have trailing
tokens after the main object and fails the request with a parsing exception otherwise.
Closes#28995
Some features have been deprecated since `6.0` like the `_parent` field or the
ability to have multiple types per index. This allows to remove quite some
code, which in-turn will hopefully make it easier to proceed with the removal
of types.
Today when a user runs a CLI tool with standard input closed and no tty
attached, the result from reading is null and this usually leads to a
null pointer exception when we try to parse this input. This arises for
example when the user runs the plugin installer through a Docker
container without leaving standard input open and attaching a tty
(docker exec <container ID> bin/elasticsearch-plugin install). When we
try to read that the user accepts the plugin requiring additional
security permissions we will get back null. This commit addresses this
for all cases by throwing an illegal state exception. The solution for
the user is leave standard input open and attach a tty (or, for some
tools, use batch mode).
#29409 removed the nearlyEquals() double comparison snippet, which
makes these tests very flaky because they can generate very large or
very small doubles which don't work well with absolute error comparison.
We need to either refactor these tests to guarantee they stay in a small
range (which could be difficult due to holt/holt-winters) or re-implement
the more robust double comparison.
Tracking issue: #29456
This commit simplifies the exception handling in
TranslogWriter#closeWithTragicEvent. When invoking this method, the
inner close method could throw an exception which we always catch and
suppress into the exception that led us to tragically close. This commit
moves that repeated logic into closeWithTragicException and now callers
simply need to catch, invoke closeWithTragicException, and rethrow.
* Remove copy-pasted code
We had two instances of copy-pasted code with a bad license from
another website. The code was doing something rather simple, and
that functionality already exists within junit. This PR simply leverages
the junit functionality.
`BaseRandomBinaryDocValuesRangeQueryTestCase.testRandomBig` should only run with
nightly tests. It doesn't make sense to make it part of every test run.
`UUIDTests` had a slow test for compression, which I made a bit faster by
decreasing the number of indexed docs.
This commit fixes the formatting of the values in the composite
aggregation response. `date` fields should return timestamp as longs
when used in a `terms` source and `ip` fields should always be formatted as strings.
This commit also fixes the parsing of the `after` key for these field types.
Finally, this commit disables the index optimization for the `ip` field and any source that provides a `missing` value.
This commit simplifies the invocations to
Translog#closeOnTragicEvent. This method already catches all possible
exceptions and suppresses the non-AlreadyClosedExceptions into the
exception that triggered the invocation. Therefore, there is no need for
callers to do this same logic (which would never execute).
* Move Streams.copy into elasticsearch-core and make a multi-release jar
This moves the method `Streams.copy(InputStream in, OutputStream out)` into the
`elasticsearch-core` project (inside the `o.e.core.internal.io` package). It
also makes this class into a multi-release class where the Java 9 equivalent
uses `InputStream#transferTo`.
This is a followup from
https://github.com/elastic/elasticsearch/pull/29300#discussion_r178147495
* Move ObjectParser into the x-content lib
This moves `ObjectParser`, `AbstractObjectParser`, and
`ConstructingObjectParser` into the libs/x-content dependency. This decoupling
allows them to be used for parsing for projects that don't want to depend on the
entire Elasticsearch jar.
Relates to #28504
* Move Tuple into elasticsearch-core
This allows us to use Tuple from other projects that don't want to rely on the
entire Elasticsearch jar.
I have also added very simple tests, since there were none.
