* Follow up to #44165
* We should just catch all exceptions here and not return errors after the index-N update went through since a subsequent delete attempt by the user would fail with SnapshotMissingException since the snapshot now appears deleted. Also, `SnapshotException` isn't even thrown in the changed spot it seems in the first place and certainly not the only exception possible.
This commit converts all the StreamableResponseActionType security
classes in xpack core to ActionType, implementing Writeable for their
response classes.

When getting authentication info from the thread context, it might be
that we encounter an I/O exception. Today we swallow this exception and
return a null authentication info to the caller. Yet, this could be
hiding bugs or errors. This commits adjusts this behavior so that we no
longer swallow the exception.
Two new settings were introduced in #43669 to control the
behaviour of the Document Level Security BitSet cache.
This change adds documentation for these 2 settings.

The test EmptyDirTaskTests#testCreateEmptyDirNoPermissions may fail on
Windows. However, the test is only meaningful for Unix permissions
structures, so we should assume a Unix-family OS and skip the test on
Windows.
Fixes#44064
Today a cluster health request can wait on a selection of conditions, but it
does not guarantee that all of these conditions have ever held simultaneously
when it returns. More specifically, if a request sets `waitForEvents()` along
with some other conditions then Elasticsearch will respond when the master has
processed all the expected pending tasks _and then_ the cluster satisfied the
other conditions, but it may be that at the time the cluster satisfied the
other conditions there were undesired pending tasks again.
This commit adjusts the behaviour of `waitForEvents()` to wait for all the
required events to be processed and then, if the resulting cluster state does
not satisfy the other conditions, it will wait until there is a cluster state
that does and then retry the wait-for-events too.
* Fix Exceptions in EventHandler#postHandling Breaking Select Loop
* We can run into the `write` path for SSL channels when they are not fully registered (if registration fails and a close message is attempted to be written) and thus into NPEs from missing selection keys
* This is a quick fix to quiet down tests, a cleaner solution will be incoming for #44343
* Relates #44343
* Prevent Confusing Blocked Thread Warnings in MockNioTransport
* We can run into a race where the stacktrace collection and subsequent logging happens after the thread has already unblocked thus logging a confusing stacktrace of wherever the transport thread was after it became unblocked
* Fixed this by comparing whether or not the recorded timestamp is still the same before and after the stacktrace was recorded and not logging if it already changed
Test clusters currently has its own set of logic for dealing with
finding different versions of Elasticsearch, downloading them, and
extracting them. This commit converts testclusters to use the
DistributionDownloadPlugin.
Today the `BatchedRerouteService` submits its delayed reroute task at `HIGH`
priority, but in some cases a lower priority would be more appropriate. This
commit adds the facility to submit delayed reroute tasks at different
priorities, such that each submitted reroute task runs at a priority no lower
than the one requested. It does not change the fact that all delayed reroute
tasks are submitted at `HIGH` priority, but at least it makes this explicit.
This commit creates new base classes for master node actions whose
response types still implement Streamable. This simplifies both finding
remaining classes to convert, as well as creating new master node
actions that use Writeable for their responses.

Today we do not throw a `TranslogCorruptedException` in certain cases of
translog corruption, such as for a corrupted checkpoint file or when an
expected file (either checkpoint or translog) is completely missing. This means
that `elasticsearch-shard` will not truncate the translog in those cases.
This commit strengthens the translog corruption tests to corrupt and/or delete
both translog and checkpoint files, and ensures that a
`TranslogCorruptedException` is thrown in all cases. It also sometimes
simulates a recovery after a crash while rolling the translog generation,
including cases where the rolled checkpoint contains incorrect data.
It also adjusts (and renames) `RemoveCorruptedShardDataCommandIT.getDirs()` to
return only a single path, since in practice this was the only thing that could
happen and yet we were relying on its callers to verify this and not all
callers were doing so.
* Stronger Cleanup Shard Snapshot Directory on Delete
* Use `RepositoryData` to clean up unreferenced `snap-${uuid}.dat` blobs
from shard directories (and index-N) and as a result also clean up data
blobs that are only referenced by them
* Stop cleaning up anything but index-N on shard snapshot creation to
align behavior of shard index-N handling with root path index-N
handling
The responses super.writeTo() method was removed in #44092, so the corresponding
contructor that reads from a stream shouldn't call super itself, even though its
implementation is currently empty.
* Avoid Needless Set Instantiation in InboundMessage
* When `features` is empty (when there's no xpack) we constantly and needless instantiated a few objects here for the empty set on every message
* At least all the way back to 6.x we never use anything but `SMILE` in
production code with this class so I removed the more general
constructor and removed the format leniency from the deserialization
* HLRC: Fix '+' Not Correctly Encoded in GET Req.
* Encode `+` correctly as `%2B` in URL paths
* Keep encoding `+` as space in URL parameters
* Closes#33077
This commit modifies bwc behavior in FindFileStructureAction to check
against a concrete version instead of Version.CURRENT. Checking against
Version.CURRENT does not work since it is changing, in addition to it
having different meanings on each branch.

An indexing on a replica should never fail after it was successfully
indexed on a primary. Hence, we should fail an engine if we hit any
failure (document level or tragic failure) when processing an indexing
on a replica.

Currently we loose information about whether a token list in an AnalyzeAction
response is null or an empty list, because we write a 0 value to the stream in
both cases and deserialize to a null value on the receiving side. This change
fixes this so we write an additional flag indicating whether the value is null
or not, followed by the size of the list and its content.
Closes#44078
Rewrites how continuous data frame transforms calculates and handles buckets that require an update. Instead of storing the whole set in memory, it pages through the updates using a 2nd cursor. This lowers memory consumption and prevents problems with limits at query time (max_terms_count). The list of updates can be re-retrieved in a failure case (#43662)
This commit moves the Supplier variant of HandledTransportAction to have
a different ordering than the Writeable.Reader variant. The Supplier
version is used for the legacy Streamable, and currently having the
location of the Writeable.Reader vs Supplier in the same place forces
using casts of Writeable.Reader to select the correct super constructor.
This change in ordering allows easier migration to Writeable.Reader.

This is a refactor to current JSON logging to make it more open for extensions
and support for custom ES log messages used inDeprecationLogger IndexingSlowLog , SearchSLowLog
We want to include x-opaque-id in deprecation logs. The easiest way to have this as an additional JSON field instead of part of the message is to create a custom DeprecatedMessage (extends ESLogMEssage)
These messages are regular log4j messages with a text, but also carry a map of fields which can then populate the log pattern. The logic for this lives in ESJsonLayout and ESMessageFieldConverter.
Similar approach can be used to refactor IndexingSlowLog and SearchSlowLog JSON logs to contain fields previously only present as escaped JSON string in a message field.
