As we have factored Elasticsearch into smaller libraries, we have ended
up in a situation that some of the dependencies of Elasticsearch are not
available to code that depends on these smaller libraries but not server
Elasticsearch. This is a good thing, this was one of the goals of
separating Elasticsearch into smaller libraries, to shed some of the
dependencies from other components of the system. However, this now
means that simple utility methods from Lucene that we rely on are no
longer available everywhere. This commit copies IOUtils (with some small
formatting changes for our codebase) into the fold so that other
components of the system can rely on these methods where they no longer
depend on Lucene.
Before the `matchAllDocs` was ignored and this could lead to percolator queries not matching when
the inner query was a match_all query and min_score was specified.
Before when `verified` was not taken into account if the function_score query wrapped an unverified query this could
lead to matching percolator queries that shouldn't match at all.
This allows us to remove another dependency in the decoupling of the XContent
code. Rather than move this class over or decouple it, it can simply be removed.

Ingest has been failing to apply existing pipelines from cluster-state
into the in-memory representation that are no longer valid. One example of
this is a pipeline with a script processor. If a cluster starts up with scripting
disabled, these pipelines will not be loaded. Even though GETing a pipeline worked,
indexing operations claimed that this pipeline did not exist. This is because one
gets information from cluster-state and the other is from an in-memory data-structure.
Now, two things happen
1. suppress the exceptions until after other successful pipelines are loaded
2. replace failed pipelines with a placeholder pipeline
If the pipeline execution service encounters the stubbed pipeline, it is known that
something went wrong at the time of pipeline creation and an exception was thrown to
the user at some point at start-up.
closes#28269.
fixed bugs that were exposed by this:
* Duplicates query leafs were not detected in a multi level boolean query
* Tracking fields for numeric range queries did not work properly.
* The sorting that was used to find the less restrictive clauses in
disjunction query did not work too.
This removes the readFrom and writeTo methods from XContentType, instead using
the more generic `readEnum` and `writeEnum` methods. Luckily they are both
encoded exactly the same way, so there is no compatibility layer needed for
backwards compatibility.

* Wrap stream passed to createParser in try-with-resources
This wraps the stream (`.streamInput()`) that is passed to many of the
`createParser` instances in the enclosing (or a new) try-with-resources block.
This ensures the `BytesReference.streamInput()` is closed.

* Use try-with-resources instead of closing in a finally block
This commit makes AcknowledgedResponse implement ToXContentObject, so that the response knows how to print its own content out to XContent, which allows us to remove AcknowledgedRestListener.
* Pass InputStream when creating XContent parser
Rather than passing the raw `BytesReference` in when creating the xcontent
parser, this passes the StreamInput (which is an InputStream), this allows us to
decouple XContent from BytesReference.
This also removes the use of `commons.Booleans` so it doesn't require more
external commons classes.

* Undo boolean removal
* Enhance deprecation javadoc
Add support version and version_type in ingest pipelines
Add support for setting document version and version type in set
processor of an ingest pipeline.
* Remove log4j dependency from elasticsearch-core
This removes the log4j dependency from our elasticsearch-core project. It was
originally necessary only for our jar classpath checking. It is now replaced by
a `Consumer<String>` so that the es-core dependency doesn't have external
dependencies.
The parts of #28191 which were moved in conjunction (like `ESLoggerFactory` and
`Loggers`) have been moved back where appropriate, since they are not required
in the core jar.
This is tangentially related to #28504
* Add javadocs for `output` parameter
* Change @code to @link
* Remove deprecated createParser methods
This removes the final instances of the callers of `XContent.createParser` and
`XContentHelper.createParser` that did not pass in the `DeprecationHandler`. It
also removes the now-unused deprecated methods and fully removes any mention of
Log4j or LoggingDeprecationHandler from the XContent code.

We have code used in the networking layer to search for errors buried in
other exceptions. This code will be useful in other locations so with
this commit we move it to our exceptions helpers.

The is a follow up to #28567 changing the method used to capture stack traces, as requested
during the review. Instead of creating a throwable, we explicitly capture the stack trace of the
current thread. This should Make Jason Happy Again ™️ .
When elasticsearch was originally moved to gradle, the "provided" equivalent in maven had to be done through a plugin. Since then, gradle added the "compileOnly" configuration. This commit removes the provided plugin and replaces all uses with compileOnly.
The bug was caused because the ScriptService had no reference to a ClusterState instance,
because it received the ClusterState after the PipelineStore. This only is the case
after a restart.
A bad side effect is that during a restart, any pipeline to be loaded after the pipeline that uses a stored script,
was never loaded, which caused many pipeline to be missing in bulk / index request api calls.
Parsing of a ranking evaluation request and its subcomponents should throw parsing
errors on unknown fields. This change adds tests for this and changes the parser
behaviour in cases where it is needed.
* Move to non-deprecated XContentHelper.createParser(...)
This moves away from one of the now-deprecated XContentHelper.createParser
methods in favor of specifying the deprecation logger at parser creation time.
Relates to #28449
Note that this doesn't move all the `createParser` calls because some of them
use the already-deprecated method that doesn't specify the XContentType.
* Remove the deprecated (and now non-needed) createParser method
The initializer and afterthought were not having their types
appropriately cast which is necessary with expressions which in turn
caused values to be popped off the stack that were null.
If you call `getDates()` on a long or date type field add a deprecation
warning to the response and log something to the deprecation logger.
This *mostly* worked just fine but if the deprecation logger happens to
roll then the roll will be performed with the script's permissions
rather than the permissions of the server. And scripts don't have
permissions to, say, open files. So the rolling failed. This fixes that
by wrapping the call the deprecation logger in `doPriviledged`.
This is a strange `doPrivileged` call because it doens't check
Elasticsearch's `SpecialPermission`. `SpecialPermission` is a permission
that no-script code has and that scripts never have. Usually all
`doPrivileged` calls check `SpecialPermission` to make sure that they
are not accidentally acting on behalf of a script. But in this case we
are *intentionally* acting on behalf of a script.
Closes#28408
This commit switches all the modules and server test code to use the
non-deprecated `ParseField.match` method, passing in the parser's deprecation
handler or the logging deprecation handler when a parser is not available (like
in tests).

This change adds a shallow copy method for aggregation builders. This method returns a copy of the builder replacing the factoriesBuilder and metaDada
This method is used when the builder is rewritten (AggregationBuilder#rewrite) in order to make sure that we create a new instance of the parent builder when sub aggregations are rewritten.

Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
Factors the way in which XContent parsing handles deprecated fields
into a callback that is set at parser construction time. The goals here
are:
1. Remove Log4J as a dependency of XContent so that XContent can be used
by clients without forcing log4j and our particular deprecation handling
scheme.
2. Simplify handling of deprecated fields in tests. Now tests can listen
directly for the deprecation callback rather than digging through a
ThreadLocal.
More accurately, this change begins this work. It deprecates a number of
methods, pointing folks to the new versions of those methods that take
`DeprecationHandler`. The plan is to slowly drop these deprecated
methods. Once they are entirely removed we can remove Log4j as
dependency of XContent.
This gives the test longer to block its updates. Now that we're checking
if the updates actually blocked saw that they may not do so in the
normal 10 seconds on a highly loaded system. And our jenkins machines
often function like highly loaded systems. Maybe this fixes#26758!
This change adds support for the new ranking evaluation API to the High Level Rest Client.
This mostly means adding support for parsing the various response objects back from the
REST representation. It includes one change to the response syntax where previously we didn't
print the type of the metric details section but we now need it to pick the right parser to
parse this section back.
Closes#28198
If a percolator query contains duplicate query clauses somewhere in the query tree then
when these clauses are extracted then they should not affect the msm.
This can lead a percolator query that should be a valid match not become a candidate match,
because at query time, the msm that is being used by the CoveringQuery would never match with
the msm used at index time.
Closes#28315
This commit updates netty to 4.1.16.Final. This is the latest version that we can have work without
extra permissions. This updated version of netty fixes issues seen with Java 9 and some data
not being sent, which results in timeouts.
The rethrottle test fails from time to time because one of the child
task that want to be rethrottled hasn't properly started yet. We retry
in this case but it looks like the retry either isn't long enough or
something else strange is happening.
This change adds yet more logging so future failure of this kind will be
easier to track down and it adds an extra wait condition: this waits for
all child tasks to be running or completed before rethrottling. This
*might* avoid the failure because once a child task is properly started
it should be quite ok to rethrottle.
