TL;DR This commit should not have any impact on terms aggs, it will just make
supporting ipv6 easier.
Currently only the numeric terms aggs propagate the DocValueFormat instance since
we use numerics to represent also dates or ip addresses. Since string terms aggs
are only used for text/keyword/string fields, they do not use the format and just
call toUt8String(). However when we support ipv6, ip addresses as well will be
encoded in sorted doc values (just like strings) so we will need to use the
DocValueFormat to format the keys.
CBOR is natively supported in Elasticsearch and allows for byte arrays.
This means, that by using CBOR the user can prevent base64 conversions
for the data being sent back and forth.
This PR adds support to extract data from a byte array in addition to
a string. This also required to add a ByteArrayValueSource class.
In #17133 we introduce request size limit handling and need a custom
channel implementation. In order to ensure we delegate all methods
it is better to have this channel implement an interface instead of
an abstract base class (so changes on the interface turn into
compile errors).

Sometimes we get a test failure caused by search contexts left open.
The tests include a stack trace of the call that opened the context
but nothing else about the context. This adds more information about
the context that has been left open like what query it was running,
what shard it targeted, and whether or not it was a scroll.

When you implement an ingest factory which implements `Closeable`:
```java
public static final class Factory extends AbstractProcessorFactory<MyProcessor> implements Closeable {
@Override
public void close() throws IOException {
logger.debug("closing my processor factory");
}
}
```
The `close()` method is never called which could lead to some leak threads when we close a node.
The `ProcessorsRegistry#close()` method exists though and seems to do the right job:
```java
@Override
public void close() throws IOException {
List<Closeable> closeables = new ArrayList<>();
for (Processor.Factory factory : processorFactories.values()) {
if (factory instanceof Closeable) {
closeables.add((Closeable) factory);
}
}
IOUtils.close(closeables);
}
```
But apparently this method is never called in `Node#stop()`.
Closes#17625.
We have both `Settings.settingsBuilder` and `Settings.builder` that do exactly
the same thing, so we should keep only one. I kept `Settings.builder` since it
has my preference but also it is the one that we use in examples of the Java API.
* Create one AllField field per field eligible for _all.
* Add a positionIncrementGap (with a size of 100, not configurable) between
each entry in order to distinguish fields when doing phrase query on _all.
This removes the inconsistent output of IP addresses. The format was parsing-unfriendly and it makes it hard
to reason about API responses, such as to _nodes.
With this change in place, it will never print the hostname as part of the default format, which has the
added benefit that it can be used consistently for URIs, which was not the case when the hostname might
appear at the front with "hostname/ip:port".
CORS headers and methods config parameters must be read as arrays. This
commit fixes the issue. It affects http.cors.allow-methods and
http.cors.allow-headers.
Fixes#17483
Aggregations need to perform instanceof calls on MappedFieldType instances in
order to know how they should be parsed or formatted. Instead, we should let
the field types provide a formatter/parser that can can be used.
This change makes the root (/) rest api delegate to a transport action to get the
data for the response. This aligns this rest api with all of the other apis, which
delegate to one or more actions.
In doing this, unit tests were added to provide coverage of the RestMainAction
and the associated classes.
Because sigma is also used at reduce time, it should be passed to empty aggs.
Otherwise it causes bugs when an empty aggregation is used to perform reduction
is it would assume a sigma of zero.
Closes#17362
The doc mentions match_path in one place but the correct syntax is path_match which is mentioned everywhere else. Using the wrong string leads to errors because the mapping becomes too greedy, and matches things it shouldn't.
