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.
Closes#17956
* Register `indices.query.bool.max_clause_count` setting
This commit registers `indices.query.bool.max_clause_count` as a node
level setting and removes support for its synonym setting
`index.query.bool.max_clause_count`.

FSync translog outside of the writers global lock
Today we aquire a write global lock that blocks all modification to the
translog file while we fsync / checkpoint the file. Yet, we don't necessarily
needt to block concurrent operations here. This can lead to a lot of blocked
threads if the machine has high concurrency (lot os CPUs) but uses slow disks
(spinning disks) which is absolutely unnecessary. We just need to protect from
fsyncing / checkpointing concurrently but we can fill buffers and write to the
underlying file in a concurrent fashion.
This change introduces an additional lock that we hold while fsyncing but moves
the checkpointing code outside of the writers global lock.
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.
Closes#18326
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).

- Moves recovery logic into IndexShard
- Simplifies logic to cancel peer recovery of shard where recovery source node changed
- Ensures routing entry is set on initialization of IndexShard
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.
Closes#18325
This commit adds a variety of real disk metrics for the block devices
that back Elasticsearch data paths. A collection of statistics are read
from /proc/diskstats and are used to report the raw metrics for
operations and read/write bytes.

This commit refactors the JvmGcMonitorService so that it can be
tested. In particular, hooks are added to verify that the
JvmMonitorService correctly observes slow GC events, and that the
JvmGcMonitorService logs the correct messages.

Instead of re-exposing index metadata and blocks in RoutingNodes (which is part of the cluster state before rerouting), expose it as part of the RoutingAllocation which is known to be only temporarily used during reroute.
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.
With this commit we add a precondition check to BulkRequest so
we fail early if users pass `null` for the request object.

Today, a race condition exists when retiring executors. Namely, if an
executor is retired and then the thread pool is terminated, the retiring
of the executor and the termination of the thread pool can race to
remove the retired executor from the queue of retired executors. More
precisely, when the executor is initially retired, it is placed on a
queue of retired executors, and then removed when it is successfully
shutdown. When the pool is terminated, it will also drain the queue of
retired executors. This leads to a time-of-check-time-of-use race where
the draining can see a retired executor on the queue but that retired
executor can be removed upon successful shutdown of that executor. This
leads to the draining attempting to remove an element from the queue
when there is none. This commit addresses this race condition by instead
safely polling the queue.

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.
Relates to #10598
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.
Resolves#17114
Currently terms on an ip address try to put their binary representation in the
json response. With this commit, they would return a formatted ip address:
```
"buckets": [
{
"key": "192.168.1.7",
"doc_count": 1
}
]
```
We add support to explicitly exclude specific transport actions
from the request size limit check.
We also exclude the following request types currently:
*MasterPingRequest
* PingRequest
As most of our log messages are not sentences and do not end with

This commit ensures that if CORS is enabled, then Origin headers are
checked regardless of whether the request came from a browser or not.
In the past, we only proceeded with CORS checks if the User-Agent was a
browser.
(same name and UUID) exists in the cluster state. This resolves a
situation where if an index data folder was copied into a node's data
directory while the node is running and that index had a tombstone in
the cluster state, the index would still get imported.

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.
This commit modifies two logging statements in the
IndexingMemoryController to log the key for the setting
indices.memory.index_buffer_size instead of the object.

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.
Today when join validation fails, we log a warning but do not log the
exception that led to the join validation failing. This commit modifies
this so that we do log this exception.
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.)
With this commit we eagerly evaluate content length in HttpServer
and also pass the same value to ResourceHandlingHttpChannel. With
this change it easier to reason about the content length that is
freed leaving no doubt that it must be identical to the reserved
amount.
Most of the current implementations of BaseNodesResponse (plural Nodes) ignore FailedNodeExceptions.
- This adds a helper function to do the grouping to TransportNodesAction
- Requires a non-null array of FailedNodeExceptions within the BaseNodesResponse constructor
- Reads/writes the array to output
- Also adds StreamInput and StreamOutput methods for generically reading and writing arrays
