Instead of being lenient in QueryParseContext#parseInnerQueryBuilder we check that the token where the parser stopped reading was END_OBJECT, and throw error otherwise. This is a best effort to verify that the parsers read a whole object rather than stepping out in the middle of it due to malformed queries.
Fuzzy Query, like many other queries, used to parse even when the query referred to multiple fields and the first one would win. We rather throw an exception now instead.
Also added test for short prefix query variant and modified the parsing code to consume the whole query object.

Closes#19547
When we introduces [persistent node ids](https://github.com/elastic/elasticsearch/pull/19140) we were concerned that people may copy data folders from one to another resulting in two nodes competing for the same id in the cluster. To solve this we elected to not allow an incoming join if a different with same id already exists in the cluster, or if some other node already has the same transport address as the incoming join. The rationeel there was that it is better to prefer existing nodes and that we can rely on node fault detection to remove any node from the cluster that isn't correct any more, making room for the node that wants to join (and will keep trying).
Sadly there were two problems with this:
1) One minor and easy to fix - we didn't allow for the case where the existing node can have the same network address as the incoming one, but have a different ephemeral id (after node restart). This confused the logic in `AllocationService`, in this rare cases. The cluster is good enough to detect this and recover later on, but it's not clean.
2) The assumption that Node Fault Detection will clean up is *wrong* when the node just won an election (it wasn't master before) and needs to process the incoming joins in order to commit the cluster state and assume it's mastership. In those cases, the Node Fault Detection isn't active.
This PR fixes these two and prefers incoming nodes to existing node when finishing an election.
On top of the, on request by @ywelsch , `AllocationService` synchronization between the nodes of the cluster and it's routing table is now explicit rather than something we do all the time. The same goes for promotion of replicas to primaries.
Adds `warnings` syntax to the yaml test that allows you to expect
a `Warning` header that looks like:
```
- do:
warnings:
- '[index] is deprecated'
- quotes are not required because yaml
- but this argument is always a list, never a single string
- no matter how many warnings you expect
get:
index: test
type: test
id: 1
```
These are accessible from the docs with:
```
// TEST[warning:some warning]
```
This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.
AbstractQueryTestCase parses the main version of the query in strict mode, meaning that it will fail if any deprecated syntax is used. It should do the same for alternate versions (e.g. short versions). This is the way it is because the two alternate versions for ids query are both deprecated. Moved testing for those to a specific test method that isolates the deprecations and actually tests that the two are deprecated.
Factor rounding and Interval rounding (the non-date based rounding)
was no longer used so it has been removed. Offset rounding has been
retained for no since both date based rounding classes rely on it
When closing a transport client that depends on Netty 4, interrupted
exceptions can be thrown while shutting down some Netty threads. This
commit refactors the handling of these exceptions to finish shutting
down and then just restore the interrupted status.
Today if the PreBuiltTransportClient is using Netty 4 transport, on
shutdown some Netty 4 threads could linger. This commit causes the
client to wait for these threads to shutdown upon termination.
This change does three things:
1. Makes PreBuiltTransportClientTests run since it was silently
failing on a missing dependency
2. Makes PreBuiltTransportClientTests pass
3. Removes the http.type and transport.type from being set in the
transport clients additional settings since these are set to `netty4` by
default anyway.
Fixes an issue where a node that receives a cluster state
update with a brand new cluster UUID but without an
initial persistence block could cause indices to be wiped out,
preventing them from being reimported as dangling indices.
This commit only removes the in-memory data structures and
thus, are subsequently reimported as dangling indices.
A primary shard currently instructs the master to fail a replica shard that it fails to replicate writes to before acknowledging the writes to the client. To ensure that the primary instructing the master to fail the replica is still the current primary in the cluster state on the master, it submits not only the identity of the replica shard to fail to the master but also its own shard identity. This can be problematic however when the primary is relocating. After primary relocation handoff but before the primary relocation target is activated, the primary relocation target is replicating writes through the authority of the primary relocation source. This means that the primary relocation target should probably send the identity of the primary relocation source as authority. However, this is not good enough either, as primary shard activation and shard failure instructions can arrive out-of-order. This means that the relocation target would have to send both relocation source and target identity as authority. Fortunately, there is another concept in the cluster state that represents this joint authority, namely primary terms. The primary term is only increased on initial assignment or when a replica is promoted. It stays the same however when a primary relocates.
This commit changes ShardStateAction to rely on primary terms for shard authority. It also changes the wire format to only transmit ShardId and allocation id of the shard to fail (instead of the full ShardRouting), so that the same action can be used in a subsequent PR to remove allocation ids from the active allocation set for which there exist no ShardRouting in the cluster anymore. Last but not least, this commit also makes AllocationService less lenient, requiring ShardRouting instances that are passed to its applyStartedShards and applyFailedShards methods to exist in the routing table. ShardStateAction, which is calling these methods, now has the responsibility to resolve the ShardRouting objects that are to be started / failed, and remove duplicates.
Today, when listing thread pools via the cat thread pool API, thread
pools are listed in a column-delimited format. This is unfriendly to
command-line tools, and inconsistent with other cat APIs. Instead,
thread pools should be listed in a row-delimited format.
Additionally, the cat thread pool API is limited to a fixed list of
thread pools that excludes certain built-in thread pools as well as all
custom thread pools. These thread pools should be available via the cat
thread pool API.
This commit improves the cat thread pool API by listing all thread pools
(built-in or custom), and by listing them in a row-delimited
format. Finally, for each node, the output thread pools are sorted by
thread pool name.

This commit increases the Netty 3 REST test suite timeout to thirty
minutes. This is to address these tests running slowly after increasing
the number of nodes in the tests to two. This has surfaced that the
tests are heavily impacted by excessive fsyncs from most tests using the
default number of shards of five.
The `loggerUsageCheck` can only run on directories that exist. It was
checking whether or not the directories exists before they were built
built and then deciding to do no work. But only if you are building in
a cleaned environment which CI does, but people rarely do locally.
With the security permissions that we grant to Netty, Netty can not
access unsafe (because it relies on having the runtime permission
accessDeclaredMembers and the reflect permission
suppressAccessChecks). Instead, we should just explicitly tell Netty to
not use unsafe. This commit adds a flag to the default jvm.options to
tell Netty to not look for unsafe.
