* We only had the `size == 0` optimization in some but not all spots of deserializing collections in this class, fixed the remaining spots.
* Also fixed the a similar spot when deserializing `ThreadContextStruct` that could now be simplified (it was apparently doing it's own version of this optimization for the first map it deserialized before ... but not for the second map -> made it not instantiate anything if both maps are empty since it's always the same object here anyway)
* Optimize some StreamOutput Operations
* Writing numbers byte by byte adds a lot of unnecessary bounds checks to serialization
* Serializing to a threadlocal `byte[]` instead and bulk writing gives about a 50% speedup on `long` and `vlong` (for large numbers) writes and 30% for `int`, `vint` on Linux on an i9
* Using a threadlocal of the maximum string buffer size we used to allocate before also removes allocations when writing strings in general since we now never have to allocate a `byte[]` for that
* And don't have to GC one either resolving the TODO removed here
This commit converts all remaining TransportRequest and
TransportResponse classes to implement Writeable, and disallows
Streamable implementations.

NamedAnalyzer should return the same AnalysisMode than any custom analyzer it
wraps, otherwise AnalysisMode.ALL. This used to be only CustomAnalyzer in the
past, but with the introduction of the ReloadableCustomAnalyzer this needs to be
added as an option where the analysis mode gets propagated.

backport that was causing this #44178
This commit converts several utility classes that implement Streamable
to have StreamInput constructors. It also adds a default version of
readFrom to Streamable so that overriding to throw UOE is not necessary.

This commit converts several more classes from streamable to writeable
in server, mostly within the o.e.index and o.e.persistent packages.

This commit converts subclasses of ShardOperationFailedException to
implement ctors with StreamInput instead of readFrom. It also simplifies
IndicesShardStoresResponse.Failure to serialize its shardId after the
super data.

A tool to work with snapshots.
Co-authored by @original-brownbear.
This commit adds snapshot tool and the single command cleanup, that
cleans up orphaned files for S3.
Snapshot tool lives in x-pack/snapshot-tool.

Today we reroute the cluster as part of the process of starting a shard, which
runs at `URGENT` priority. In large clusters, rerouting may take some time to
complete, and this means that a mere trickle of shard-started events can cause
starvation for other, lower-priority, tasks that are pending on the master.
However, it isn't really necessary to perform a reroute when starting a shard,
as long as one occurs eventually. This commit removes the inline reroute from
the process of starting a shard and replaces it with a deferred one that runs
at `NORMAL` priority, avoiding starvation of higher-priority tasks.
Backport of #44433 and #44543.
Multi search accepts multiple search requests and runs them as
independent requests, each one as part of their own search task. Today
they don't get associated though with their parent multi search task,
which would be useful to monitor which msearch a certain search was part
of, if any, and also to cancel all of the sub-requests in case the
parent msearch gets cancelled (though this will also require making
the multi search task cancellable as a follow-up).
Today the long list of `BUILT_IN_CLUSTER_SETTINGS` is indented differently
between `master` and `7.x`. This sometimes makes backporting painful. This
commit adjusts the indentation of earlier branches to match that in `master`.
* Many messages deserialized from a `StreamInput` only contain short strings, some use-cases of instantiating a `StreamInput` don't deserialize any strings
* Don't allocate `CharsRef` for small strings to save some allocations (especially on the IO threads)
* Lazily allocate a larger `CharsRef` if needed for larger strings like we did before and have it live as long as the `StreamInput` like before as well
This commit deprecates all constructors of HandledTransportAction
that take in a Supplier instead of a Writeable.Reader for response
objects.
in addition to the deprecation, the following modules were updated to
leverage Writeable
- modules:ingest-common
- modules:lang-mustache
relates #34389.
this commit removes usage of the deprecated
constructor with a single argument and no Writeable.Reader.
The purpose of this is to reduce the boilerplate necessary for
properly implementing a new action, as well as reducing the
chances of using the incorrect super constructor while classes
are being migrated to Writeable
relates #34389.
This commit converts all remaining ActionType response classes to
writeable in xpack core. It also converts a few from server which were
used by xpack core.

Today we have an annotation for controlling logging levels in
tests. This annotation serves two purposes, one is to control the
logging level used in tests, when such control is needed to impact and
assert the behavior of loggers in tests. The other use is when a test is
failing and additional logging is needed. This commit separates these
two concerns into separate annotations.
The primary motivation for this is that we have a history of leaving
behind the annotation for the purpose of investigating test failures
long after the test failure is resolved. The accumulation of these stale
logging annotations has led to excessive disk consumption. Having
recently cleaned this up, we would like to avoid falling into this state
again. To do this, we are adding a link to the test failure under
investigation to the annotation when used for the purpose of
investigating test failures. We will add tooling to inspect these
annotations, in the same way that we have tooling on awaits fix
annotations. This will enable us to report on the use of these
annotations, and report when stale uses of the annotation exist.
This commit adds constructors to AcknolwedgedRequest subclasses to
implement Writeable.Reader, and ensures all future subclasses implement
the same.

Large histories can be problematic and have the linearizability checker occasionally run OOM. As it's
very difficult to bound the size of the histories just right, this PR will let it instead run for 10 seconds
on large histories and then abort.

Extracts dateline decomposition logic from ShapeBuilder into a separate
utility class that is used on the indexing side. The search side
will be handled as part of another PR at this time we will remove
the decomposition logic from ShapeBuilders as well. This PR also doesn't

Due to https://issues.apache.org/jira/browse/LUCENE-8916, when you
try to use a synonym filter with the index_phrases option on a text field,
you can end up with null values in a Phrase query, leading to weird
exceptions further down the querying chain. As a workaround, this commit
disables the index_phrases optimization for queries that produce token
graphs.
Fixes#43976
Zen 1 stops pinging threads in ZenDiscovery by calling Thread.interrupt(). This is incompatible with
the CancellableThreads that only allow threads to be interrupted through cancellation. The use of
CancellableThreads was introduced in #42844 and added to UnicastZenPing as part of the
backport, as both Zen1 and Zen2 share the same SeedHostsResolver implementation. This commit
effectively undoes the change in the backport while still allowing to share same implementation.
Closes#44425
BucketScript was using the old-style parser and could easily be

Also adds a test for GapPolicy enum serialization
Today we report an exception on a handshake failure (e.g. cluster name
mismatch) but the message does not include all the details of the mismatch. If
the mismatch is something subtle like `my-cluster` instead of `my_cluster` then
we cannot diagnose this from the message alone. This commit adds the details of
the local cluster to the message, along with the details of the remote cluster,
improving the utility of the exception message if reported in isolation.
* Fix Incorrect Uncompressed Error Handling in InboundMessage
* CompressorFactory.compressor does not throw uncompressed exception on uncompressed bytes, it merely returns `null` in this case if the bytes are at least XContent so the current catch and re-throw logic is dead code
* Made it work again by throwing on a `null` return so we get a real error message instead of an NPE
* We only use this method in one place in production code and can replace that with a read -> remove it to simplify the interface
* Keep it as an implementation detail in the Azure repository
In #44348 we changed the cluster health action so that it sometimes uses the
cluster state directly from the master service rather than from the cluster
applier. If the state is not recovered then this is inappropriate, because
prior to state recovery the state available to the cluster applier contains no
indices. This commit moves us back to using the state from the applier.
Fixes#44416.
Today when the cluster health changes the `AllocationService` reports at most
ten shards that were started or failed, and always ends its message with `...`
suggesting that the list is truncated. This commit adjusts these messages to be
clearer about whether the list is truncated or not. When debug logging is
enabled the list is not truncated; if the list is truncated then its length is
logged, and if it is not truncated then no `...` is included in the message.
This commit converts the request and response classes for broadcast
actions to implement ctors for Writeable.Reader and forces all future
implementations to implement the same.
