From 2.0 adding child types to existing types was forbidden because the`_parent` field stores the join between parent and child at index time.
This is to protect from the fact that types that weren't a parent before become a parent while previously indexed documents would not have a join field.
This would break the parent/child queries.
The restriction was a bit too strict in the sense that also if a type was a parent type the restriction would forbid adding child types that point to a parent type (so child points already point to it).
This change make sure that the restriction only applies if that type isn't a parent type already.

Currently rounding intervals obtained by nextRoundingValue() for hour, minute and
second units can include an extra hour when happening at DST transitions that add
an extra hour (eg CEST -> CET). This changes the rounding logic for time units
smaller or equal to an hour to fix this.

This commit adds simple GC overhead logging. This logging captures
intervals where the JVM is spending a lot of time performing GC but it
is not necessarily the case that each GC is large. For a start, this
logging is simple and does not attempt to incorporate whether or not the
collections were efficient (that is, we are only capturing that a lot of
GC is happening, not that a lot of useless GC is happening).

With this commit we clear all caches after testing the parent circuit breaker.
This is necessary as caches hold on to circuit breakers internally. Additionally,
due to usage of CircuitBreaker#addWithoutBreaking() in caches, it's even possible
to go above the limit. As a consequence, all subsequent requests fall victim to
the limit.
Hence, right after the parent circuit breaker tripped, we clear all caches to
reduce these circuit breakers to 0 again. We also exclude the clear caches
transport request from limit check in order to ensure it will succeed. As this is
typically a very small and low-volume request, it is deemed ok to exclude it.

Sorts an array of values in ascending or descending order. If all elements are numerics, they will be sorted numerically. If values are strings, or mixtures of strings/numbers, the elements will be sorted lexicographically.
The change also renames fields and methods in the Profilers class.
Note that I had to make ProfileResult a public class (it was package private before) because now classes that call it are in a different package.
This change does the following:
- Queries that are currently unsupported such as prefix queries on numeric
fields or term queries on geo fields now throw an error rather than returning
a query that does not match anything.
- Fuzzy queries on numeric, date and ip fields are now unsupported: they used
to create range queries, we now expect users to use range queries directly.
Fuzzy, regexp and prefix queries are now only supported on text/keyword
fields (including `_all`).
- The `_uid` and `_id` fields do not support prefix or range queries anymore as
it would prevent us to store them more efficiently in the future, eg. by
using a binary encoding.
Note that it is still possible to ignore these errors by using the `lenient`
option of the `match` or `query_string` queries.
Previously multiple extensions could be provided, however, this can lead
to confusion with on-disk scripts (ie, "foo.js" and "foo.javascript")
having different content. Only a single extension is now supported.
The only language currently supporting multiple extensions was the
Javascript engine ("js" and "javascript"). It now only supports the
`.js` extension.

Currently `fuzziness` is not supported for the `cross_fields` type
of the `multi_match` query since it complicates the logic that
blends the term queries that cross_fields uses internally. At the
moment using this combination is silently ignored, which can lead to
confusions. Instead we should throw an exception in this case.
The same is true for phrase and phrase_prefix type.
Closes#7764
This commit adds a test that a fixed executors rejected count behaves as
expected. In particular, we test that if we consume the executor, then
stuff the executor queue, further tasks will be rejected and the
rejected stats are updated appropriately. This test also asserts that if
we resize the queue the rejected count is reset to zero.

This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:
```yaml
script.inline: sandbox
script.stored: sandbox
```
Instead, only a `true` or `false` value can be specified.
Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:
```yaml
script.engine.groovy.inline: true
```
Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).
Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.

situation where if an index data folder was copied into a node's data

It will keep using the caching terms enum for keyword/text fields and falls back
to IndexSearcher.count for fields that do not use the inverted index for
searching (such as numbers and ip addresses). Note that this probably means that
significant terms aggregations on these fields will be less efficient than they
used to be. It should be ok under a sampler aggregation though.
This moves tests back to the state they were in before numbers started using
points, and also adds a new test that significant terms aggs fail if a field is
not indexed.
In the long term, we might want to follow the approach that Robert initially
proposed that consists in collecting all documents from the background filter in
order to compute frequencies using doc values. This would also mean that
significant terms aggregations do not require fields to be indexed anymore.
An additional sanity check introduced by #17821 makes some tests fail. This check verifies that
only one shard with same shard id is allocated to a node. This commit fixes a bug in
ClusterStateCreationUtils which would construct a cluster state that allocated two shards with same
id to the same node.
All implementations of SearchParseElement have been removed since they are no longer used now that parsing is done on the coordinating node. The SearchParseElement and FetchSubPhaseParseElement classes are not removed as currently they are needed for plugins that add a custom fetch sub phase. These will be removed in a follow up PR that will allow fetch sub phase plugins to register a parser in a different way.
The current code tries to handle the case that document versions are either
missing or stored in payloads rather than doc values. Since none of the 2.x
releases allowed this, we can remove this logic.
This removes dead/duplicate code and makes the `_index` field not configurable.
(Configuration used to jus be ignored, now we would throw an exception if any
is provided.)
Most of the current implementations of BaseNodesResponse (plural Nodes) ignore FailedNodeExceptions.

We should prevent highlighting if a field is anything but a text or keyword field.
However, someone might implement a custom field type that has text and still want to
highlight on that. We cannot know in advance if the highlighter will be able to
highlight such a field and so we do the following:
If the field is only highlighted because the field matches a wildcard we assume
it was a mistake and do not process it.
If the field was explicitly given we assume that whoever issued the query knew
what they were doing and try to highlight anyway.

The `ip` field uses a binary representation internally. This breaks when

QueryBuilder has generics, but those are never used: all call sites use

Today we softly warn about running with the client VM. However, we

platforms on server-class machines (2+ CPUs, 2+ GB physical RAM) this is
the default and on all 64-bit platforms this is the only option) and
adds a bootstrap check for the client VM.

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.

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.
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.

With this commit we compress HTTP responses provided the client

We're also able to process compressed HTTP requests if needed.
The default compression level is lowered from 6 to 3 as benchmarks

increase in network traffic.

Today when running in production mode the bootstrap checks are
completely unforgiving. But there are cases where an end-user might not
have the ability to modify some of the system-level settings that cause
the bootstrap checks to trip (e.g., guest settings that are inherited
from a host and can not be modified). This commit adds a setting that
allows system-level bootstrap checks to be ignored for these
end-users. We classify certain bootstrap checks into system-level checks
and only those bootstrap checks will be ignored if this flag is
enabled. All other bootstrap checks are still subject to being enforced
if the user is in production mode. We will still log warnings for these
bootstrap checks because the end-user does still need to be made aware
that they are running in a configuration that is less-than-ideal from a
resiliency perspective.

This commit removes a racy but unnecessary assertion in scaling thread
pool idle test. Namely, the main test thread can reach the removed
assertion before the last few threads in the thread pool have completed
their tasks and caused the completed tasks count on the underlying
executor to be updated. But this assertion is unnecessary. The main test
thread already waits on a latch that is only decremented immediately
before a task completes. This ensures that it was in fact the case that
every submitted task was executed.

This commit modifes the EsThreadPoolTestCase#info helper method to
return null when info for the thread pool can not be found. This really
should only happen for the "same" thread pool, and so we also assert
that we only get to a place where there is no info if the thread pool
that info was requested for is in fact the "same" thread pool. Not
returning null here and instead throwing an exception would fail tests
that tried to lookup info on the "same" thread pool.
Fix a limitation that prevent from hierarchical inner hits be defined in query dsl.

Previously like in other geo related query parsers we were using
a combination of two booleans for coerce and ignore_malformed
which was error prone and not very clear.
Switched to using GeoValidationMethod instead as we already do
e.g. in GeoBoundingBoxQueryBuilder.
Left support for both, coerce and ignore_malformed in the parser
but deprecated the two in favour of validation method.
Introduced the same deprecation in geo bounding box query builder.
While returning no hits on fields that are not mapped may be fine, it is not
for fields that are mapped but not indexed (`index:false`). We should fail the

Awesome. But ObjectParser doesn't support building things objects whose

This commit fixes a test bug in the scaling thread pool idle
test. Namely, a random thread pool is chosen which could have a min pool
size of one or four but the while loop was acting as if the min pool
size was four (this is due to the test having been initially written for
only the generic thread pool).
Additionally, a latch is added between the test thread and the work
tasks to reduce the chance of a race condition between the test thread
and last few tasks.
This commit slightly expands the scaling thread pool configuration test
coverage. In particular, the test testScalingThreadPoolConfiguration is
expanded to include the case when min is equal to size, and the test
testDynamicThreadPoolSize is expanded to include all possible cases when
size is greater than or equal to min.
Previously, we would determine index deletes in the cluster state by
comparing the index metadatas between the current cluster state and the
previous cluster state and decipher which ones were missing (the missing
ones are deleted indices). This led to a situation where a node that
went offline and rejoined the cluster could potentially cause dangling
indices to be imported which should have been deleted, because when a node
rejoins, its previous cluster state does not contain reliable state.
This commit introduces the notion of index tombstones in the cluster
state, where we are explicit about which indices have been deleted.
In the case where the previous cluster state is not useful for index
metadata comparisons, a node now determines which indices are to be
deleted based on these tombstones in the cluster state. There is also
functionality to purge the tombstones after exceeding a certain amount.

This commit clarifies an error message that is produced when an attempt
is made to resize the backing queue for a scaling executor. As this
queue is unbounded, resizing the backing queue does not make sense. The
clarification here is to specify that this restriction is because the
executor is a scaling executor.
This commit actually bounds the size of the generic thread pool. The
generic thread pool was of type cached, a thread pool with an unbounded
number of workers and an unbounded work queue. With this commit, the
generic thread pool is now of type scaling. As such, the cached thread
pool type has been removed. By default, the generic thread pool is
constructed with a core pool size of four, a max pool size of 128 and
idle workers can be reaped after a keep-alive time of thirty seconds
expires. The work queue for this thread pool remains unbounded.
The list settings parser supports retrieving lists defined in settings that use a key followed by a `.` and a
number (for example `foo.bar.0`). However, the exists method would indicate that the provided settings
do not contain a value for this setting. This change makes it so that the exists method now handles this
format.
When a cli throws a USAGE error, it is implied that the user did
something wrong, and probably needs help in understanding the cli
arguments. This change adds help output before the usage error is

Do this by creating a Client subclass that automatically assigns the
parentTask to all requests that come through it. Code that doesn't want
to set the parentTask can call `unwrap` on the Client to get the inner
client instance that doesn't set the parentTask. Reindex uses this for
its ClearScrollRequest so that the request will run properly after the
reindex request has been canceled.
Now that the current uses of magical camelCase support have been
deprecated, we can remove these in master (sans remaining issues like
BulkRequest). This change removes camel case support from ParseField,
query types, analysis, and settings lookup.

Don't pass XContentParser to ParseFieldRegistry#lookup
Passing the parser in is not good because we are not parsing anything in the lookup methods, we only need it to retrieve the xcontent location from it so that in case there is an error we emit where we were with the parsing. It is better to pass in the XContentLocation although calling getTokenLocation needs to create a new object at each call. The workaround of passing the Parser in is worse than the original problem.

Now there aren't any more specialized methods to read or write

about large chunks of the application!
When I pulled on the thread that is "Remove PROTOTYPEs from

and replacing it with readNamedWriteable. That seems like a lot at once
but it made sense at the time. And it is what we want in the end, I think.
Anyway, this also converts registration of SignificanceHeuristics to
use ParseFieldRegistry to make them consistent with Queries, Aggregations
and lots of other stuff.

This only applies for new indices created on 5.0 and later. Indices created on previous versions the .percolator type is still allowed to exist.

The `PercolatorQueryBuilder` will not enforce that the `field` parameter is of type `percolator`.
This commit refactors the UUID-generating methods out of Strings into
their own class. The primary motive for this refactoring is to avoid a
chain of class initializers from loading this class earlier than
necessary. This was discovered when it was noticed that starting
Elasticsearch without any active network interfaces leads to some
logging statements being executed before logging had been
initailized. Thus:
- these UUID methods have no place being on Strings
- removing them reduces spooky action-at-distance loading of this class
- removed the troublesome, logging statements from MacAddressProvider,
logging using statically-initialized instances of ESLogger are prone
to this problem
