There are some parameters that are accepted by each and every api we expose. Those (pretty, source, error_trace and filter_path) are not explicitly listed in the spec of every api, rather whitelisted in clients test runners so that they are always accepted. The `human` flag has been treated up until now as a parameter that's accepted by only some stats and info api, but that doesn't reflect reality as es core treats it exactly like `pretty` (relevant especially now that we validate params and throw exception when we find one that is not supported). Furthermore, the human flag has effect on every api that outputs a date, time, percentage or byte size field. For instance the tasks api outputs a date field although they don't have the human flag explicitly listed in their spec. There are other similar cases. This commit removes the human flag from the rest spec and makes it an always accepted query_string param.
This change disables the _all meta field by default.
Now that we have the "all-fields" method of query execution, we can save both
indexing time and disk space by disabling it.
_all can no longer be configured for indices created after 6.0.

TcpTransport has an actual mechanism to stop resources in subclasses.
Instead of overriding `doStop` subclasses should override `stopInternal`
that is executed under the connection lock guaranteeing that there is no
concurrency etc.

Today when you do not specify a port for an entry in
discovery.zen.ping.unicast.hosts, the default port is the value of the
setting transport.profiles.default.port and falls back to the value of
transport.tcp.port if this is not set. For a node that is explicitly
bound to a different port than the default port, this means that the
default port will be equal to this explicitly bound port. Yet, the docs
say that we fall back to 9300 here. This commit corrects the docs.

* Settings: Make s3 repository sensitive settings use secure settings
This change converts repository-s3 to use the new secure settings. In
order to support the multiple ways we allow aws creds to be configured,
it also moves the main methods for the keystore wrapper into a
SecureSettings interface, in order to allow settings prefixing to work.
Adds a message about how the remote is unlikely to be Elasticsearch.
This isn't as good as including the whole message from the remote but
we can't do that because we are stream parsing it and we don't want
to mark the whole request.
Closes#22330
* Fix Translog.Delete serialization for sequence numbers
Translog.Delete used `.writeVLong` instead of `.writeLong` for the sequence
number and primary term (and their respective "read" variants). This could lead
to issues where a 5.x node sent a translog operation with a negative sequence
number (-2 for unassigned seq no) that tripped an assertion serializing a
negative number and causing ES to exit.
Adds a unit test for serialization and a mixed-cluster REST test, since that was
how this was originally caught.
* Use more realistic values for random seqNum and primary term
* Add comment with TODO for removal in 7.0
* Change comment into an assert
The config template that ships with Elasticsearch distributions contains
links to various pieces of documentation. Links go out of date and get
broken. This commit removes such links from the config template.

The low level TCP handshake can cause channel / connection leaks if it's interrupted
since the caller doesn't close the channel / connection if the handshake was not successful.
This commit fixes the channel leak and adds general test infrastructure to detect channel leaks
in the future.
Instead of `search.remote.seeds.${clustername}` we now specify the seeds as:
`search.remote.${clustername}.seeds` which is a real list setting compared to an unvalidated
group setting before.
Fix the `Dockerfile` example in the `Customizing image` third configuration
method by adding the missing RUN instruction.

Today affix settings are not dynamic since it's required to know
it's namespace in order to pull a concrete setting from it. This is not possible
in practice since the namespaces are dynamic by design. This change allows to register
a specialized settings consumer that consumes the namespace and the actual value if
a setting gets updated.
Moves fetching the local node id into `NodeClient` which is a
fairly useful place to put it so you can generate task ids from
`NodeClient#executeLocally`.
This commit reverts switching to the unpooled allocator (for now) to let
some benchmarks run to see if this is the source of an increase in GC
times.

This commit adds the parsing fromXContent() methods to the IndexResponse class. The method is based on a ObjectParser because it is easier to use when parsing parent abstract classes like DocWriteResponse.
It also changes the ReplicationResponse.ShardInfo so that it now implements ToXContentObject. This way, the ShardInfo.fromXContent() method can be used by the IndexResponse's ObjectParser.
Previously, we removed all unneeded backward compatibility logic
from the BlobStoreRepository because 6.0 does not need to support
2.x snapshot formats. During the process of removing this backward
compatibility logic, some code was leftover that is no longer
necessary. This commit removes all the remaining unnecessary
backwards compatibility code in BlobStoreRepository.
#9261 added a warning about the use of `add-apt-repository` which is becoming obsolete over time as new distribution releases include later versions of `add-apt-repository` which don't automatically add the `deb-src` line. This change updates the documentation to make the block a note rather than a warning and adds two other reasons for avoiding `add-apt-repository` which are still relevant: avoiding edits to a system shared file and not requiring a large number of non-default packages to add one line of text to a file.
The example
```
/<logstash-{now/d-2d}>,<logstash-{now/d-1d}>,<logstash-{now/d}>/_search
```
shows escaped URL where `, => %2C`, so I assume it should be escaped and be present in the table
It is no longer needed. It used to contain a lot of strings
used by serialization but those have since been removed. Now
it is just another thing to pass around that we don't really
need.
