Transition transport apis to use void listeners (#27440)
Currently we use ActionListener<TcpChannel> for connect, close, and send
message listeners in TcpTransport. However, all of the listeners have to
capture a reference to a channel in the case of the exception api being
called. This commit changes these listeners to be type <Void> as passing
the channel to onResponse is not necessary. Additionally, this change
makes it easier to integrate with low level transports (which use
different implementations of TcpChannel).

Ensure nested documents have consistent version and seq_ids (#27455)
Today we index dummy values for seq_ids and version on nested documents.
This is on the one hand trappy since users can request these values via
inner hits and on the other hand not necessarily good for compression since
the dummy value will likely not compress well when seqIDs are lowish.

This change ensures that we share the same field values for all documents in a
nested block. This won't have any overhead, in-fact it might be more efficient since
we even reduce the work needed slightly.

Make fields optional in multi_match query and rely on index.query.default_field by default (#27380)
* Make fields optional in multi_match query and rely on index.query.default_field by default

This commit adds the ability to send `multi_match` query without providing any `fields`.
When no fields are provided the `multi_match` query will use the fields defined in the index setting `index.query.default_field`
(which in turns defaults to `*`).
The same behavior is already implemented in `query_string` and `simple_query_string` so this change just applies
the heuristic to `multi_match` queries.
Relying on `index.query.default_field` rather than `*` is safer for big mappings that break the 1024 field expansion limit added in 7.0 for all
text queries. For these kind of mappings the admin can change the `index.query.default_field` in order to make sure that exploratory queries using
`multi_match`, `query_string` or `simple_query_string` do not throw an exception.

Remove parameterization from TcpTransport (#27407)
This commit is a follow up to the work completed in #27132. Essentially
it transitions two more methods (sendMessage and getLocalAddress) from
Transport to TcpChannel. With this change, there is no longer a need for
TcpTransport to be aware of the specific type of channel a transport
returns. So that class is no longer parameterized by channel type.

Add composite aggregator (#26800)
* This change adds a module called `aggs-composite` that defines a new aggregation named `composite`.
The `composite` aggregation is a multi-buckets aggregation that creates composite buckets made of multiple sources.
The sources for each bucket can be defined as:
  * A `terms` source, values are extracted from a field or a script.
  * A `date_histogram` source, values are extracted from a date field and rounded to the provided interval.
This aggregation can be used to retrieve all buckets of a deeply nested aggregation by flattening the nested aggregation in composite buckets.
A composite buckets is composed of one value per source and is built for each document as the combinations of values in the provided sources.
For instance the following aggregation:

````
"test_agg": {
  "terms": {
    "field": "field1"
  },
  "aggs": {
    "nested_test_agg":
      "terms": {
        "field": "field2"
      }
  }
}
````
... which retrieves the top N terms for `field1` and for each top term in `field1` the top N terms for `field2`, can be replaced by a `composite` aggregation in order to retrieve **all** the combinations of `field1`, `field2` in the matching documents:

````
"composite_agg": {
  "composite": {
    "sources": [
      {
	"field1": {
          "terms": {
              "field": "field1"
            }
        }
      },
      {
	"field2": {
          "terms": {
            "field": "field2"
          }
        }
      },
    }
  }
````

The response of the aggregation looks like this:

````
"aggregations": {
  "composite_agg": {
    "buckets": [
      {
        "key": {
          "field1": "alabama",
          "field2": "almanach"
        },
        "doc_count": 100
      },
      {
        "key": {
          "field1": "alabama",
          "field2": "calendar"
        },
        "doc_count": 1
      },
      {
        "key": {
          "field1": "arizona",
          "field2": "calendar"
        },
        "doc_count": 1
      }
    ]
  }
}
````

By default this aggregation returns 10 buckets sorted in ascending order of the composite key.
Pagination can be achieved by providing `after` values, the values of the composite key to aggregate after.
For instance the following aggregation will aggregate all composite keys that sorts after `arizona, calendar`:

````
"composite_agg": {
  "composite": {
    "after": {"field1": "alabama", "field2": "calendar"},
    "size": 100,
    "sources": [
      {
	"field1": {
          "terms": {
            "field": "field1"
          }
        }
      },
      {
	"field2": {
          "terms": {
            "field": "field2"
          }
	}
      }
    }
  }
````

This aggregation is optimized for indices that set an index sorting that match the composite source definition.
For instance the aggregation above could run faster on indices that defines an index sorting like this:

````
"settings": {
  "index.sort.field": ["field1", "field2"]
}
````

In this case the `composite` aggregation can early terminate on each segment.
This aggregation also accepts multi-valued field but disables early termination for these fields even if index sorting matches the sources definition.
This is mandatory because index sorting picks only one value per document to perform the sort.

Add TcpChannel to unify Transport implementations (#27132)
Right now our different transport implementations must duplicate
functionality in order to stay compliant with the requirements of
TcpTransport. They must all implement common logic to open channels,
close channels, keep track of channels for eventual shutdown, etc.

Additionally, there is a weird and complicated relationship between
Transport and TransportService. We eventually want to start merging
some of the functionality between these classes.

This commit starts moving towards a world where TransportService retains
all the application logic and channel state. Transport implementations
in this world will only be tasked with returning a channel when one is
requested, calling transport service when a channel is accepted from
a server, and starting / stopping itself.

Specifically this commit changes how channels are opened and closed. All
Transport implementations now return a channel type that must comply with
the new TcpChannel interface. This interface has the methods necessary
for TcpTransport to completely manage the lifecycle of a channel. This
includes setting the channel up, waiting for connection, adding close
listeners, and eventually closing.

Stop responding to ping requests before master abdication (#27329)
When the current master node is shutting down, it sends a leave request to the other nodes so that they can eagerly start a fresh master election. Unfortunately, it was still possible for the master node that was shutting down to respond to ping requests, possibly influencing the election decision as it still appeared as an active master in the ping responses. This commit ensures that UnicastZenPing does not respond to ping requests once it's been closed. ZenDiscovery.doStop() continues to ensure that the pinging component is first closed before it triggers a master election.

This is the first step to supporting WKT (and other future) format(s). The ShapeBuilders are quite messy and can be simplified by decoupling the parse logic from the build logic. This commit refactors the parsing logic into its own package separate from the Shape builders. It also decouples the GeoShapeType into a standalone enumerator that is responsible for validating the parsed data and providing the appropriate builder. This future-proofs the code making it easier to maintain and add new shape types.

Fail queries with scroll that explicitely set request_cache (#27342)
Queries that create a scroll context cannot use the cache.
They modify the search context during their execution so using the cache
can lead to duplicate result for the next scroll query.

This change fails the entire request if the request_cache option is explictely set
on a query that creates a scroll context (`scroll=1m`) and make sure internally that we never
use the cache for these queries when the option is not explicitely used.
For 6.x a deprecation log will be printed instead of failing the entire request and the request_cache hint
will be ignored (forced to false).

Ensure external refreshes will also refresh internal searcher to minimize segment creation (#27253)
We cut over to internal and external IndexReader/IndexSearcher in #26972 which uses
two independent searcher managers. This has the downside that refreshes of the external
reader will never clear the internal version map which in-turn will trigger additional
and potentially unnecessary segment flushes since memory must be freed. Under heavy
indexing load with low refresh intervals this can cause excessive segment creation which
causes high GC activity and significantly increases the required segment merges.

This change adds a dedicated external reference manager that delegates refreshes to the
internal reference manager that then `steals` the refreshed reader from the internal
reference manager for external usage. This ensures that external and internal readers
are consistent on an external refresh. As a sideeffect this also releases old segments
referenced by the internal reference manager which can potentially hold on to already merged
away segments until it is refreshed due to a flush or indexing activity.

Remove optimisations to reuse objects when applying a new `ClusterState` (#27317)
In order to avoid churn when applying a new `ClusterState`, there are some checks that compare parts of the old and new states and, if equal, the new object is discarded and the old one reused. Since `ClusterState` updates are now largely diff-based, this code is unnecessary: applying a diff also reuses any old objects if unchanged. Moreover, the code compares the parts of the `ClusterState` using their `version()` values which is not guaranteed to be correct, because of a lack of consensus.

This change removes this optimisation, and tests that objects are still reused as expected via the diff mechanism.

TemplateUpgradeService should only run on the master (#27294)
The `TemplateUpgradeService` allows plugins to register a call back that mutates index templates upon recovery. This is handy for upgrade logic that needs to make sure that an existing index template is updated once the cluster is upgraded to a new version of the plugin (and ES).

Currently, the service has complicated logic to decide which node should perform the upgrade. It will prefer the master node, if it is of the highest version of the cluster and otherwise it will fall back to one of the non-coordinating nodes which are on the latest version. While this attempts to make sure that new nodes can assume their template version is in place (but old node still need to be able to operate under both old and new template), it has an inherent problem in that the master (on an old version) may not be able to process the put template request with the new template - it may miss certain features.

This PR changes the logic to be simpler and always rely on the current master nodes. This comes at the price that new nodes need to operate both with old templates and new. That price is small as they need to operate with old indices regardless of the template. On the flip side we reduce a lot of complexity in what can happen in the cluster.

we encounter an anonymous class, we need to grab the super's name.

Another naming issue was that ProfileAggs were not delegating to the
wrapped agg's name for toString(), leading to ugly display.

This PR also fixes up the profile documentation.  Some of the examples were
executing against empty indices, which shows different profile results
than a populated index (and made for confusing examples).

Finally, I switched the agg display names from the fully qualified name
to the simple name, so that it's similar to how the query profiles work.

Correctly encode warning headers
The warnings headers have a fairly limited set of valid characters
(cf. quoted-text in RFC 7230). While we have assertions that we adhere
to this set of valid characters ensuring that our warning messages do
not violate the specificaion, we were neglecting the possibility that
arbitrary user input would trickle into these warning headers. Thus,
missing here was tests for these situations and encoding of characters
that appear outside the set of valid characters. This commit addresses
this by encoding any characters in a deprecation message that are not
from the set of valid characters.

Simon Willnauer bd7efa908a Add ability to split shards (#26931)
This change adds a new `_split` API that allows to split indices into a new
index with a power of two more shards that the source index.  This API works
alongside the `_shrink` API but doesn't require any shard relocation before
indices can be split.

The split operation is conceptually an inverse `_shrink` operation since we
initialize the index with a _syntetic_ number of routing shards that are used
for the consistent hashing at index time. Compared to indices created with
earlier versions this might produce slightly different shard distributions but
has no impact on the per-index backwards compatibility.  For now, the user is
required to prepare an index to be splittable by setting the
`index.number_of_routing_shards` at index creation time.  The setting allows the
user to prepare the index to be splittable in factors of
`index.number_of_routing_shards` ie. if the index is created with
`index.number_of_routing_shards: 16` and `index.number_of_shards: 2` it can be
split into `4, 8, 16` shards. This is an intermediate step until we can make
this the default. This also allows us to safely backport this change to 6.x.

The `_split` operation is implemented internally as a DeleteByQuery on the
lucene level that is executed while the primary shards execute their initial
recovery. Subsequent merges that are triggered due to this operation will not be
executed immediately. All merges will be deferred unti the shards are started
and will then be throttled accordingly.

This change is intended for the 6.1 feature release but will not support pre-6.1
indices to be split unless these indices have been shrunk before. In that case
these indices can be split backwards into their original number of shards.

If the master disconnects from the cluster after initiating snapshot, but just before the snapshot switches from INIT to STARTED state, the snapshot can get indefinitely stuck in the INIT state. This error is specific to v5.x+ and was triggered by keeping the master node that stepped down in the node list, the cleanup logic in snapshot/restore assumed that if master steps down it is always removed from the the node list.

Lazy initialize checkpoint tracker bit sets
This local checkpoint tracker uses collections of bit sets to track
which sequence numbers are complete, eventually removing these bit sets
when the local checkpoint advances. However, these bit sets were eagerly
allocated so that if a sequence number far ahead of the checkpoint was
marked as completed, all bit sets between the "last" bit set and the bit
set needed to track the marked sequence number were allocated. If this
sequence number was too far ahead, the memory requirements could be
excessive. This commit opts for a different strategy for holding on to
these bit sets and enables them to be lazily allocated.

Enhances exists queries to reduce need for `_field_names` (#26930)
* Enhances exists queries to reduce need for `_field_names`

Before this change we wrote the name all the fields in a document to a `_field_names` field and then implemented exists queries as a term query on this field. The problem with this approach is that it bloats the index and also affects indexing performance.

This change adds a new method `existsQuery()` to `MappedFieldType` which is implemented by each sub-class. For most field types if doc values are available a `DocValuesFieldExistsQuery` is used, falling back to using `_field_names` if doc values are disabled. Note that only fields where no doc values are available are written to `_field_names`.

When a search is executing locally over many shards, we can stack
overflow during query phase execution. This happens due to callbacks
that occur after a phase completes for a shard and we move to the same
phase on another shard. If all the shards for the query are local to the
local node then we will never go async and these callbacks will end up
as recursive calls. With sufficiently many shards, this will end up as a
stack overflow. This commit addresses this by truncating the stack by
forking to another thread on the executor for the phase.

Return the _source of inner hit nested as is without wrapping it into its full path context
Due to a change happened via #26102 to make the nested source consistent
with or without source filtering, the _source of a nested inner hit was
always wrapped in the parent path. This turned out to be not ideal for
users relying on the nested source, as it would require additional parsing
on the client side. This change fixes this, the _source of nested inner hits
is now no longer wrapped by parent json objects, irregardless of whether
the _source is included as is or source filtering is used.

Internally source filtering and highlighting relies on the fact that the
_source of nested inner hits are accessible by its full field path, so
in order to now break this, the conversion of the _source into its binary
form is performed in FetchSourceSubPhase, after any potential source filtering
is performed to make sure the structure of _source of the nested inner hit
is consistent irregardless if source filtering is performed.

Lee Hinman 78c54c4560 Balance shards for an index more evenly across multiple data paths (#26654)
* Balance shards for an index more evenly across multiple data paths

When a node has multiple data paths configured, and is assigned all of the
shards for a particular index, it's possible now that all shards will be
assigned to the same path (see #16763).

This change keeps the same behavior around determining the "best" path for a
shard based on space, however, it enforces limits for the number of shards on a
path for an index from the single-node perspective. For example:

Assume you had a node with 4 data paths, where `/path1` has a tremendously high
amount of disk space available compared to the other paths. If you create an
index with 5 primary shards, the previous behavior would be to assign all 5
shards to `/path1`.

This change would enforce a limit of 2 shards to each data path for that
particular node, so you would end up with the following distribution:

- `/path1` - 2 shards (because it has the most usable space)
- `/path2` - 1 shard
- `/path3` - 1 shard
- `/path4` - 1 shard

Note, however, that this limit is only enforced at the local node level for
simplicity in implementation, so if you had multiple nodes, the "limit" for the
node is still 2, so assuming you had enough nodes that there was only 2 shards
for this index assigned to this node, they would still both be assigned to
`/path1`.

Jason Tedor 62bf3c11a9 Stop invoking non-existant syscall
Today when getting ready to enter seccomp, we do some probes to ensure
that we are really talking to seccomp, etc. One of these probes is pure
paranoia. The paranoia was driven by a kernel bug
(https://lkml.org/lkml/2014/7/20/222) that only impacted 32-bit x86
kernels wherein invoking a non-existant syscall was not returning ENOSYS
(as it should). This probe causes problems though, for example in
containers with syscall filters, invoking a non-existant syscall will
lead to the process being sent SIGSYS and terminated. We do not need
this paranoid, we do not support 32-bit, and our other probes give us
enough of a defense to ensure that we are talking to seccomp (and we
hardcode the seccomp syscall number for platforms that we
support). Given that this probe offers us little value, but does cause
problems in valid use-cases, this commit removes this paranoia.

Simon Willnauer 21eb9bdf6a Use separate searchers for "search visibility" vs "move indexing buffer to disk (#26972)
Today, when ES detects it's using too much heap vs the configured indexing
buffer (default 10% of JVM heap) it opens a new searcher to force Lucene to move
the bytes to disk, clear version map, etc.

But this has the unexpected side effect of making newly indexed/deleted
documents visible to future searches, which is not nice for users who are trying
to prevent that, e.g. #3593.

This is also an indirect spinoff from #26802 where we potentially pay a big
price on rebuilding caches etc. when updates / realtime-get is used. We are
refreshing the internal reader for realtime gets which causes for instance
global ords to be rebuild. I think we can gain quite a bit if we'd use a reader
that is only used for GETs and not for searches etc. that way we can also solve
problems of searchers being refreshed unexpectedly aside of replica recovery /
relocation.

Colin Goodheart-Smithe e1679bfe5e Create weights lazily in filter and filters aggregation (#26983)
Previous to this change the weights for the filter and filters aggregation were created in the `Filter(s)AggregatorFactory` which meant that they were created regardless of whether the aggregator actually collects any documents. This meant that for filters that are expensive to initialise, requests would not be quick when the query of the request was (or effectively was) a `match_none` query.

This change maintains a single Weight instance for each filter across parent buckets but passes a weight supplier to the aggregator instances which will create the weight on first call and then return that instance for subsequent calls.

the only nodes preference was used as a replacement of `_primary` which was removed. Sadly, it's not the same as we also check that it makes sense - i.e., that the given node has a shard copy. Since the test uses indices with >1 shards, the primaries may be spread to multiple nodes. Using one (like it currently does) will fail for some primaries. Using all will probably end up hitting all nodes.

Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.

With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting.  Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.

Luca Cavanna 9b9cb81c41 Fix serialization errors when cross cluster search goes to a single shard (#26881)
The single shard optimization that we have in our search api changes the type of response returned by the query transport action name based on the shard search request. if the request goes to one shard, we will do query and fetch at the same time, hence the response will be different. The proxying layer used in cross cluster search was not aware of this distinction, which causes serialization issues every time a cross cluster search request goes to a single shard and goes through a gateway node which has to forward the shard request to a data node. The coordinating node would then expect a QueryFetchSearchResult while the gateway would return a QuerySearchResult.

David Roberts a292740b9e Add cgroup memory usage/limit to OS stats on Linux (#26166)
This change adds cgroup memory usage/limit to the OS stats section of
the node stats on Linux.  This information is useful because in Docker
containers the standard node stats report the host memory limit, not
taking account of extra restrictions that may have been applied to the
container.

The original idea was to store these values as Long, truncating any values
outside the range of long.  However, this meant that in the relatively common
case of no limit being applied, users would not see the same value in the OS
stats as they see by querying Linux directly.  So instead the values are stored
as String.  This change places a burden on consumers of the strings to
convert the strings to numbers and decide what to do about extremely large
values, but there will be very few consumers and they would need to have a
policy for dealing with "no limit" in any case.

Simon Willnauer 7b8d036ab5 Replace group map settings with affix setting (#26819)
We use group settings historically instead of using a prefix setting which is more restrictive and type safe. The majority of the usecases needs to access a key, value map based on the _leave node_ of the setting ie. the setting `index.tag.*` might be used to tag an index with `index.tag.test=42` and `index.tag.staging=12` which then would be turned into a `{"test": 42, "staging": 12}` map. The group settings would always use `Settings#getAsMap` which is loosing type information and uses internal representation of the settings. Using prefix settings allows now to access such a method type-safe and natively.

Elasticsearch doesn't allow having an index alias named with the same name as an existing index. We currently have logic that tries to prevents that in the `MetaData.Builder#build()` method.

This commit fixes the above and improves the error message while at it.

Note that we have a lot of protections in place before we end up relying on the metadata builder (validating this when we process APIs). I takes quite an abuse of the cluster to get that far.

Boaz Leskes ec0c621072 `IndexShard.routingEntry` should only be updated once all internal state is ready (#26776)
The routing entry is used by external components to check whether the shard is ready to perform as primary. Most notably, the peer recovery source handler delays recoveries until the shard routing entry says the shard is ready. 

When a shard is promoted to primary, we currently update the shard's routing entry before we finish all the work relating to the promotion. This can cause recoveries to fail later on because the `GlobalCheckpointTracker` isn't set (yet) to primary mode. 

This commit fixes this issue by updating the routing entry last.

aggs: Changed how top_hits initialises leaf collectors
Both TopDocsCollector and LeafCollector were being kept around at the aggregator level. In case the nested aggregator would do a post collection then this could cause pushing down docids to top hits child aggregators that already moved the next LeafCollector (causing assertions to trip and incorrect results).

By keeping track of the LeafCollector in a seperate map at the leaf bucket level this problem can simply not happen any more as the place holding LeafCollector is no longer shared.

Also LeafCollector instances for TopDocsCollectors are no longer pre-created as the beginning a new segment is evaluated. There is no guarantee that TopHitsAggregator encounters a document for a particular bucket and there has to be logic to create LeafCollector instances which have not been seen before.

Jason Tedor f35d1de502 Introduce global checkpoint background sync
It is the exciting return of the global checkpoint background
sync. Long, long ago, in snapshot version far, far away we had and only
had a global checkpoint background sync. This sync would fire
periodically and send the global checkpoint from the primary shard to
the replicas so that they could update their local knowledge of the
global checkpoint. Later in time, as we sped ahead towards finalizing
the initial version of sequence IDs, we realized that we need the global
checkpoint updates to be inline. This means that on a replication
operation, the primary shard would piggy back the global checkpoint with
the replication operation to the replicas. The replicas would update
their local knowledge of the global checkpoint and reply with their
local checkpoint. However, this could allow the global checkpoint on the
primary to advance again and the replicas would fall behind in their
local knowledge of the global checkpoint. If another replication
operation never fired, then the replicas would be permanently behind. To
account for this, we added one more sync that would fire when the
primary shard fell idle. However, this has problems:
 - the shard idle timer defaults to five minutes, a long time to wait
   for the replicas to learn of the new global checkpoint
 - if a replica missed the sync, there was no follow-up sync to catch
   them up
 - there is an inherent race condition where the primary shard could
   fall idle mid-operation (after having sent the replication request to
   the replicas); in this case, there would never be a background sync
   after the operation completes
 - tying the global checkpoint sync to the idle timer was never natural

To fix this, we add two additional changes for the global checkpoint to
be synced to the replicas. The first is that we add a post-operation
sync that only fires if there are no operations in flight and there is a
lagging replica. This gives us a chance to sync the global checkpoint to
the replicas immediately after an operation so that they are always kept
up to date. The second is that we add back a global checkpoint
background sync that fires on a timer. This timer fires every thirty
seconds, and is not configurable (for simplicity). This background sync
is smarter than what we had previously in the sense that it only sends a
sync if the global checkpoint on at least one replica is lagging that of
the primary. When the timer fires, we can compare the global checkpoint
on the primary to its knowledge of the global checkpoint on the replicas
and only send a sync if there is a shard behind.

Boaz Leskes 04385a9ce9 Restoring from snapshot should force generation of a new history uuid (#26694)
Restoring a shard from snapshot throws the primary back in time violating assumptions and bringing the validity of global checkpoints in question. To avoid problems, we should make sure that a shard that was restored will never be the source of an ops based recovery to a shard that existed before the restore. To this end we have introduced the notion of `histroy_uuid` in #26577 and required that both source and target will have the same history to allow ops based recoveries. This PR make sure that a shard gets a new uuid after restore.

As suggested by @ywelsch , I derived the creation of a `history_uuid` from the `RecoverySource` of the shard. Store recovery will only generate a uuid if it doesn't already exist (we can make this stricter when we don't need to deal with 5.x indices). Peer recovery follows the same logic (note that this is different than the approach in #26557, I went this way as it means that shards always have a history uuid after being recovered on a 6.x node and will also mean that a rolling restart is enough for old indices to step over to the new seq no model). Local shards and snapshot force the generation of a new translog uuid.

Boaz Leskes 1ca0b5e9e4 Introduce a History UUID as a requirement for ops based recovery (#26577)
The new ops based recovery, introduce as part of  #10708, is based on the assumption that all operations below the global checkpoint known to the replica do not need to be synced with the primary. This is based on the guarantee that all ops below it are available on primary and they are equal. Under normal operations this guarantee holds. Sadly, it can be violated when a primary is restored from an old snapshot. At the point the restore primary can miss operations below the replica's global checkpoint, or even worse may have total different operations at the same spot. This PR introduces the notion of a history uuid to be able to capture the difference with the restored primary (in a follow up PR).

The History UUID is generated by a primary when it is first created and is synced to the replicas which are recovered via a file based recovery. The PR adds a requirement to ops based recovery to make sure that the history uuid of the source and the target are equal. Under normal operations, all shard copies will stay with that history uuid for the rest of the index lifetime and thus this is a noop. However, it gives us a place to guarantee we fall back to file base syncing in special events like a restore from snapshot (to be done as a follow up) and when someone calls the truncate translog command which can go wrong when combined with primary recovery (this is done in this PR).

We considered in the past to use the translog uuid for this function (i.e., sync it across copies) and thus avoid adding an extra identifier. This idea was rejected as it removes the ability to verify that a specific translog really belongs to a specific lucene index. We also feel that having a history uuid will serve us well in the future.

Adrien Grand 454cfc2cea More efficient encoding of range fields. (#26470)
This PR removes the vInt that precedes every value in order to know how long
they are. Instead the query takes an enum that tells how to compute the length
of values: for fixed-length data (ip addresses, double, float) the length is a
constant while longs and integers use a variable-length representation that
allows the length to be computed from the encoded values.

Also the encoding of ints/longs was made a bit more efficient in order not to
waste 3 bits in the header. As a consequence, values between -8 and 7 can now
be encoded on 1 byte and values between -2048 and 2047 can now be encoded on 2
bytes or less.

Jason Tedor b3e7e85cf1 Let search phases override max concurrent requests
If the query coordinating node is also a data node that holds all the
shards for a search request, we can end up recursing through the can
match phase (because we send a local request and on response in the
listener move to the next shard and do this again, without ever having
returned from previous shards). This recursion can lead to stack
overflow for even a reasonable number of indices (daily indices over a
sixty days with five shards per day is enough to trigger the stack
overflow). Moreover, all this execution would be happening on a network
thread (the thread that initially received the query). With this commit,
we allow search phases to override max concurrent requests. This allows
the can match phase to avoid recursing through the shards towards a
stack overflow.

When determining if a build is a snapshot build, we look for a field in

classes on the classpath. We have a fallback for this, we always assume
such a situation is a snapshot build. However, when running builds with
-Dbuild.snapshot=false, this is not the case. As such, we need to
fallback to the value of build.snapshot. However, there are cases where
we are not running with a compiled core Elasticsearch JAR (e.g., when
the transport client is embedded in a web container) so we should only
do this fallback if we are in tests. To verify we are in tests, we check
if randomized runner is on the classpath.
