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.

Our parsing code accepted up until now queries in the following form (note that the query starts with `[`:
```
{
"bool" : [
{
"must" : []
}
]
}
```
This would lead to a null pointer exception as most parsers assume that the field name ("must" in this example) is the first thing that can be found in a query if its json is valid, hence always non null while parsing. Truth is that the additional array layer doesn't make the json invalid, hence the following code fragment would cause NPE within ParseField, because null gets passed to `parseContext.isDeprecatedSetting`:
```
if (token == XContentParser.Token.FIELD_NAME) {
currentFieldName = parser.currentName();
} else if (parseContext.isDeprecatedSetting(currentFieldName)) {
// skip
} else if (token == XContentParser.Token.START_OBJECT) {
```
We could add null checks in each of our parsers in lots of places, but we rely on `currentFieldName` being non null in all of our parsers, and we should consider it a bug when these unexpected situations are not caught explicitly. It would be best to find a way to prevent such queries altogether without changing all of our parsers.
The reason why such a query goes through is that we've been allowing a query to start with either `[` or `{`. The only reason I found is that we accept `match_all : []`. This seems like an undocumented corner case that we could drop support for. Then we can be stricter and accept only `{` as start token of a query. That way the only next token that the parser can encounter if the json is valid (otherwise the json parser would barf earlier) is actually a field_name, hence the assumption that all our parser makes hold.
The downside of this is simply dropping support for `match_all : []`

Sorry for the longer stack trace, but I wanted to be sure I didn't throw
anything away by accident.
* master:

[TEST] Increase time waiting for all shards to move off/on to a node
Fixes the active shard count check in the case of (#19760)
Fixes cat tasks operation in detailed mode
ignore some docker craziness in scccomp environment checks
We just overwrite `toString()` method so it calls toXContent
with `group_by` = "whatever" so we don't try to group by nodes
which does not make sense in a toString() method.
We keep the old behavior for `toXContent()` method which
means that there is no impact in the REST layer but
only in logs and tests (where we call `toString()`).
Closes#19772.
To run the tests we have to use now `*Yaml*IT` instead of `RestIT`:
```sh
gradle :distribution:integ-test-zip:integTest -Dtests.class=org.elasticsearch.test.rest.*Yaml*IT
```
