The test ping and waited for the ping results to be returned but since we first return the result and then close temporary connections, assertions are tripped that expects all connections to close by end of test .

This commit checks for a null BytesReference as the value for `source`
in GetResult#sourceRef and simply returns null. Previously this would
have resulted in a NPE. While this does seem internal at first glance, it can affect
user code as a GetResponse could trigger this when the document is missing.
Additionally, the CompressorFactory#uncompressIfNeeded now requires a
non-null argument.
The recovery process started during primary relocation of shadow replicas accesses the engine on the source shard after it's been closed, which results in the source shard failing itself.
Right now closing a shard looks like it strands refresh listeners,
causing tests like
`delete/50_refresh/refresh=wait_for waits until changes are visible in search`
to fail. Here is a build that fails:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+multi_cluster_search+multijob-darwin-compatibility/4/console
This attempts to fix the problem by implements `Closeable` on
`RefreshListeners` and rejecting listeners when closed. More importantly
the act of closing the instance flushes all pending listeners
so we shouldn't have any stranded listeners on close.
Because it was needed for testing, this also adds the number of
pending listeners to the `CommonStats` object and all API to which
that flows: `_cat/nodes`, `_cat/indices`, `_cat/shards`, and
`_nodes/stats`.
In pre 2.x versions, if the repository was set to compress snapshots,
then snapshots would be compressed with the LZF algorithm. In 5.x,
Elasticsearch no longer supports the LZF compression algorithm. This
presents an issue when retrieving snapshots in a repository or upgrading
repository data to the 5.x version, because Elasticsearch throws an
exception when it tries to read the snapshot metadata because it was
compressed using LZF.
This commit gracefully handles the situation by introducing a new
incompatible-snapshots blob to the repository. For any pre-2.x snapshot
that cannot be read, that snapshot is removed from the list of active
snapshots, because the snapshot could not be restored anyway. Instead,
the snapshot is recorded in the incompatible-snapshots blob. When
listing snapshots, both active snapshots and incompatible snapshots will
be listed, with incompatible snapshots showing a `INCOMPATIBLE` state.
Any attempt to restore an incompatible snapshot will result in an
exception.
`ToXContentObject` extends `ToXContent` without adding new methods to it, while allowing to mark classes that output complete xcontent objects to distinguish them from classes that require starting and ending an anonymous object externally.
Ideally ToXContent would be renamed to ToXContentFragment, but that would be a huge change in our codebase, hence we simply document the fact that toXContent outputs fragments with no guarantees that the output is valid per se without an external ancestor.

This is related to #22116. A logIfNecessary() call makes a call to
NetworkInterface.getInterfaceAddresses() requiring SocketPermission
connect privileges. By moving this to bootstrap the logging call can be
made before installing the SecurityManager.
Today when an index is shrunk the version information is not carried over
from the source to the target index. This can cause major issues like mapping
incompatibilities for instance if an index from a previous major version is shrunk.
This commit ensures that all version information from the soruce index is preserved
when a shrunk index is created.
Closes#22373
ParseFieldMatcher as well as ParseFieldMatcherSupplier will be soon removed, hence the ObjectParser's context doesn't need to be a ParseFieldMatcherSupplier anymore. That will allow to remove ParseFieldMatcherSupplier's implementations, little by little.
The test currently checks that the recovering shard is not failed when it is not a primary relocation that has moved past the finalization step.
Checking if it has moved past that step is done by intercepting the request between the replication source and the target and checking if it has seen
then WAIT_FOR_CLUSTERSTATE action as this is the next action that is called after finalization. This action can, however, occur only after the shard was
already failed, and thus trip the assertion. This commit changes the check to look out for the FINALIZE action, independently of whether it succeeded or not.
#22325 changed the recovery retry logic to use unique recovery ids. The change also introduced an issue, however, which made it possible for the shard store to be closed under CancellableThreads, triggering assertions in the node locking logic. This commit limits the use of CancellableThreads only to the part where we wait on the old recovery target to be closed.
Today we execute the low level handshake on the TCP layer in #connectToNode.
If #openConnection is used directly, which is truly expert, no handshake is executed
which allows connecting to nodes that are not necessarily compatible. This change
moves the handshake to #openConnection to prevent bypassing this logic.
