This change makes the vagrant tasks extend LoggedExec, so that the
entire vagrant output can be dumped on failure (and completely logged
when using --info). It should help for debugging issues like #18122.
This commit introduces a handshake when initiating a light
connection. During this handshake, node information, cluster name, and
version are received from the target node of the connection. This
information can be used to immediately validate that the target node is
a member of the same cluster, and used to set the version on the
stream. This will allow us to extend APIs that are used during initial
cluster recovery without a major version change.

All other values are errors.
Add java test for throttling. We had a REST test but it only ran against
one node so it didn't catch serialization errors.
Add Simple round trip test for rethrottle request
Today we specify the client option for the JVM when executing plugin
commands. Yet, this option does nothing on a 64-bit capable JDK as such
JDKs always select the Hotspot server VM. And for 32-bit JDKs, running
plugin commands with the server VM is okay. Thus, we should just remove
this unnecessary flag and just let the default VM be selected.

* Reorganize scripting documentation
* Further changes to tidy up scripting docs
Closes#18116
* Add note about .lat/lon potentially returning null
* Added .value to expressions example
* Fixed two bad ASCIIDOC links
Adding random shuffling of xContent to InnterHitBuilderTests shows
that the scriptFields are stored in order as a list internally although
they are an unordered json objects in the query dsl.
This changes the internal representation to a set and updates
serialization accordingly.
Currently we have a lot of methods left in QueryShardContext that
take parsers or BytesReference arguments to do some xContent
parsing on the shard. While this still seems necessary in some cases
(e.g. percolation, phrase suggester), the shard context should only
be concerned with generating lucene queries from QueryBuilders.
This change removes all of the parseX() methods in favour of two
public methods toQuery(QueryBuilder) and toFilter(QueryBuilder) that
either call the query builders toFilter() or toQuery() method and
move all code required for parsing out to the respective callers.
PathTrie has a constructor that allows for an arbitrary separtor and
wildcard, but this constructor is unused and internally we always use
'/' as the separator and '*' as the wildcard. There are no tests for the
case where the separator differs from the default separator and
wildcard. This commit removes this constructor and now all instances of
PathTrie have the default separator and wildcard.
This commit removes the method Strings#splitStringToArray and replaces
the call sites with invocations to String#split. There are only two
explanations for the existence of this method. The first is that
String#split is slightly tricky in that it accepts a regular expression
rather than a character to split on. This means that if s is a string,
s.split(".") does not split on the character '.', but rather splits on
the regular expression '.' which splits on every character (of course,
this is easily fixed by invoking s.split("\\.") instead). The second
possible explanation is that (again) String#split accepts a regular
expression. This means that there could be a performance concern
compared to just splitting on a single character. However, it turns out
that String#split has a fast path for the case of splitting on a single
character and microbenchmarks show that String#split has 1.5x--2x the
throughput of Strings#splitStringToArray. There is a slight behavior
difference between Strings#splitStringToArray and String#split: namely,
the former would return an empty array in cases when the input string
was null or empty but String#split will just NPE at the call site on
null and return a one-element array containing the empty string when the
input string is empty. There was only one place relying on this behavior
and the call site has been modified accordingly.
Folds the helper class for random object generation into the
abstract sort test class. Removes a few references to ESTestCase
that were not needed due to inheriting from it along the way.
The query shard reset() method resets some internal state in the
query shard context, like clearing query names, the filter flag
or named queries. The problem with this method being public is
that it currently (miss?) used for modifying an existing context
for recursive invocatiob, but the contexts that have been reseted
that way cannot be properly set back to their previous state.
This PR is a step towards removing reset() entirely by first making
it only be used internally in QueryShardContext. In places where
reset() was used we can either create new QueryShardContexts or
modify the existing context because it is discarded afterwards anyway.
Today, the constructor for IngestDocument#FieldPath does a string
concatentation and two object allocation on every field path. This
commit removes these unnecessary operations.

With this commit we compress HTTP responses provided the client
supports it (as indicated by the HTTP header 'Accept-Encoding').
We're also able to process compressed HTTP requests if needed.
The default compression level is lowered from 6 to 3 as benchmarks
have indicated that this reduces query latency with a negligible
increase in network traffic.
Closes#7309
