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.

* 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.
This commit fixes the inequality symbol used in a test assertion in
RepositoryS3SettingsTests#testInvalidChunkBufferSizeRepositorySettings. The
inequality symbol was previously backwards but fixed in commit
cad0608cdb but fixing the inequality
symbol here was missed in that commit.
Closes#18449
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
Probably when we updated Azure SDK, we introduced a regression.
Actually, we are not able to remove files anymore.
For example, if you register a new azure repository, the snapshot service tries to create a temp file and then remove it.
Removing does not work and you can see in logs:
```
[2016-05-18 11:03:24,914][WARN ][org.elasticsearch.cloud.azure.blobstore] [azure] can not remove [tests-ilmRPJ8URU-sh18yj38O6g/] in container {elasticsearch-snapshots}: The specified blob does not exist.
```
This fix deals with that. It now list all the files in a flatten mode, remove in the full URL the server and the container name.
As an example, when you are removing a blob which full name is `https://dpi24329.blob.core.windows.net/elasticsearch-snapshots/bar/test` you need to actually call Azure SDK with `bar/test` as the path, `elasticsearch-snapshots` is the container.
To run the test, you need to pass some parameters: `-Dtests.thirdparty=true -Dtests.config=/path/to/elasticsearch.yml`
Where `elasticsearch.yml` contains something like:
```
cloud.azure.storage.default.account: account
cloud.azure.storage.default.key: key
```

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).

We are currently only parsing the array-syntax for the rescore part
in SearchSourceBuilder ("rescore" : [ {...}, {...} ]) . We also need
to support "rescore" : {...}

- 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
Two of the snippets in validate weren't working properly so they are
marked as skip and linked to this:
https://github.com/elastic/elasticsearch/issues/18254
We didn't properly handle empty parameter values. We were sending
them as the literal string "null". Now we do better and send them
as the empty string.
