Today there are several races / holes in TcpTransport and MockTcpTransport
that can allow connections to be opened and remain unclosed while the actual
transport implementation is closed. A recently added assertions in #22554 exposes
these problems. This commit fixes several issues related to missed locks or channel
creations outside of a lock not checking if the resource is still open.
Before, the default chunk size for Azure repositories was
-1 bytes, which meant that if the chunk_size was not set on
the Azure repository, nor as a node setting, then no data
files would get written as part of the snapshot (because
the BlobStoreRepository's PartSliceStream does not know
how to process negative chunk sizes).
This commit fixes the default chunk size for Azure repositories
to be the same as the maximum chunk size. This commit also
adds tests for both the Azure and Google Cloud repositories to
ensure only valid chunk sizes can be set.
Closes#22513
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.
Relates to #22554
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.
Relates #22553
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.
