As part of #40177 we have added top-level pipeline aggs to
`InternalAggregations`. Given that `QuerySearchResult` holds an
`InternalAggregations` instance, there is no need to keep on setting
top-level pipeline aggs separately. Top-level pipeline aggs can then
always be transported through `InternalAggregations`. Such change is
made in a backwards compatible manner.
IOException are never thrown in any of the existing pipeline aggregation
builders. Removing the throws IOException from the create method allows
to remove it also from a couple of other methods which ends up simplifying
AggregationPhase (one less catch).
The cat recovery API is incredibly useful. Yet it is missing the start
and stop time as an option from the output. This commit adds these as
options to the cat recovery API. We elect to make these not visible by
default to avoid breaking the output that users might rely on.
To make script_score query to have the same features
as function_score query, we need to add randomScore
function.
This function produces different
random scores on different index shards.
It is also able to produce random scores
based on the internal Lucene Document Ids.
Today if you try and insert a very large number like `1e9999999` into a long
field we first construct this number as a `BigDecimal`, convert this to a
`BigInteger` and then reject it because it is out of range. Unfortunately
making such a large `BigInteger` is rather expensive.
We can avoid this expense by performing a (weaker) range check on the
`BigDecimal` representation of incoming `long`s too.

In #33062 we introduced the `cluster.remote.*.proxy` setting for proxied
connections to remote clusters, but left it deliberately undocumented since it
needed followup work so that it could work with SNI. However, since #32517 is
now closed we can add this documentation and remove the comment about its lack
of documentation.
This commit fixes an edge case in tests where search hits are empty
after the merge but some shards returned hits. This can happen if
the total number of merged hits is less than the provided `from`.
Closes#40553
It initially mentioned the type in the exception because the type used to be
required to uniquely identify a document. This is not necessary anymore given
that indices have at most one type.
`Index` interns its name and uuid. My guess is that the main goal is to avoid
having duplicate strings in the representation of the cluster state. However
I doubt it helps much given that we have many other objects in the cluster state
that we don't try to reuse, and interning has some cost. When looking into
#40263 my profiler pointed to string interning because of the `Index` object
that is created in `QueryShardContext` as one of the bottlenecks of the
`can_match` phase.
Adds the search_as_you_type field type that acts like a text field optimized
for as-you-type search completion. It creates a couple subfields that analyze
the indexed terms as shingles, against which full terms are queried, and a
prefix subfield that analyze terms as the largest shingle size used and
edge-ngrams, against which partial terms are queried
Adds a match_bool_prefix query type that creates a boolean clause of a term
query for each term except the last, for which a boolean clause with a prefix
query is created.
The match_bool_prefix query is the recommended way of querying a search as you
type field, which will boil down to term queries for each shingle of the input
text on the appropriate shingle field, and the final (possibly partial) term
as a term query on the prefix field. This field type also supports phrase and
phrase prefix queries however
This commit adds an InboundHandler to handle inbound message processing.
With this commit, this code is moved out of the TcpTransport.
Additionally, finer grained unit tests are added to ensure that the
inbound processing works as expected
Replicated closed indices can't be indexed into or searched, and therefore don't need a shard with
full indexing and search capabilities allocated. We can save on a lot of heap memory for those
indices by not allocating a mapper service and caching infrastructure (which preallocates a constant
amount per instance). Before this change, a 1GB ES instance could host 250 replicated closed
metricbeat indices (each index with one shard). After this change, the same instance can host 7300
replicated closed metricbeat instances (not that this would be a recommended configuration). Most
of the remaining memory is in the cluster state and the IndexSettings object.
Switches "discovery.type: single-node" from using a separate implementation for single-node discovery to using the existing standard discovery implementation, with two small adaptions:
- auto-bootstrapping, but requiring initial_master_nodes not to be set.
- not actively pinging other nodes using the Peerfinder
- not allowing other nodes to join its single-node cluster (if they have e.g. been set up using regular discovery and connect to the single-disco node).
Currently there are some components of message serializer and sending
that still occur in TcpTransport. This commit makes it possible to
send a message without the TcpTransport by moving all of the remaining
application logic to the OutboundHandler. Additionally, it adds unit
tests to ensure that this logic works as expected.
This test inadvertently asserts that the election occurs after a master failure
is clean. However, messy elections are a fact of life so we should not fail on
a messy election.
This change moves this test away from an `AbstractDisruptionTestCase` since it
does not need the fault detector to be so enthusiastic, and weakens the
assertions to merely say that we ignore states published by the old master
without saying anything about the cleanliness of the election.

Java-time fails parsing composite patterns when first pattern matches only the prefix of the input. It expects pattern in longest to shortest order. Because of this constructing just one DateTimeFormatter with appendOptional is not sufficient. Parsers have to be iterated and if the parsing fails, the next one in order should be used. In order to not degrade performance parsing should not be throw exceptions on failure. Format.parseObject was used as it only returns null when parsing failed and allows to check if full input was read.

The implementation of TransportIndexAction and TransportDeleteAction as
TransportReplicationAction existed for interoperability with older 5.x nodes, as these older nodes
coordinated single index / deletes as replication requests. This BWC layer is no longer needed in 7.x,
where these single actions are now mapped to bulk requests. Completely removing the deprecated
transport actions is not possible yet if we want to keep BWC with a 6.x transport client. The best
way here is to wait for the transport client to go away and then just remove the actions.
Each cluster state publication schedules a cancellation task with the provided publication timeout
(30s by default). This scheduled cancellation keeps a reference to the publication, and therefore the
full cluster state that was published. In case of frequently updating a large cluster state, this results
in a large number of cancellation tasks keeping references to all previously published cluster states.
FilterDirectory.getPendingDeletions does not delegate, fixed
temporarily by overriding in StoreDirectory.
This in turn caused duplicate file name use after a trimUnsafeCommits
had been done, since a new IndexWriter would not consider the pending
deletes in IndexFileDeleter. This should only happen on windows (AFAIK).
Reenabled doing index updates for all tests using
IndexShardTests.indexOnReplicaWithGaps (which could fail due to above
when using mocked WindowsFS).
Added getPendingDeletions delegation to all elasticsearch
FilterDirectory subclasses that were not trivial test-only overrides to
minimize the risk of hitting this issue in another case.
This test checks that interval queries constructed against a field with no indexed
positions will throw exceptions. It uses a randomly-build IntervalsSourceProvider
against a fixed set of fields; however, the random source builder can occasionally
provide a source with a fixed field, meaning that even if the top-level query asks
for a set of intervals over a non-indexed field, the source will delegate to another
field, and no exception will be thrown.
This commit changes the test to always use a simple Match provider.

* Log Warning on Failed Blob Deletes in BlobStoreRepository
* We should not just debug log these spots, they all can and will lead to leaked files when snapshot deletion fails
Right now, the stats API only provides refresh metrics regarding
internal refreshes. This isn't very useful and somewhat misleading for
cluster administrators since the internal refreshes are not indicative
of documents being available for search.
In this PR I added a new metric for collecting external refreshes as
they occur and exposing them through the stats API. Now, calling an
endpoint for stats will yield external refresh metrics as well.

In some cases, a request to perform a retention lease action can arrive
on a primary shard before it is active. In this case, the primary shard
would not yet be in primary mode, tripping an assertion in the
replication tracker. Instead, we should not attempt to perform such
actions on an initializing shard. This commit addresses this by not
returning the primary shard in the single shard iterator if the primary
shard is not yet active.
We were accidentally not mapping the index, which meant dynamic mapping
was choosing floats for the values. This led to enough loss of precision
for the aggregated values to differ slightly from the test doubles,
which accumulated into large differences in the holt output.
This test fix adds an explicit mapping.
This commit adjusts the frequency with which CCR renews retention leases
and with which primaries sync retention leases to replicas. This helps
Lucene reclaim soft-deleted documents more aggressively, which we have
found in some use-cases can help improve performance, and either way
will help keep disk space under more control.
This is the equivalent of the `field_masking_span` query, allowing users to
merge intervals from multiple fields - for example, to search for stemmed tokens
near unstemmed tokens.
Currently, we cannot update index setting index.translog.sync_interval if index is open, because it's
not dynamic which can be updated for closed index only.
Closes#32763
A recent refactoring (#37130) where imports got mixed up (changing Lucene's
IndexNotFoundException to Elasticsearch's IndexNotFoundException) led to many warnings being
logged in case of restoring a fresh snapshot.
This change adds an option to convert a `date` field to nanoseconds resolution
and a `date_nanos` field to millisecond resolution when sorting.
The resolution of the sort can be set using the `numeric_type` option of the
field sort builder. The conversion is done at the shard level and is restricted
to dates from 1970 to 2262 for the nanoseconds resolution in order to avoid
numeric overflow.
If a replica were first reset due to one primary failover and then
promoted (before resync completes), its MSU would not include changes
since global checkpoint, leading to errors during translog replay.
Fixed by re-initializing MSU before restoring local history.
Today we don't return segments stats for closed indices which makes it
hard to tell how much memory such an index would require. With this change
we return the statistics if requested by setting `include_unloaded_segments` to
true on the rest request.

Today RareClusterStateIT#testAssignmentWithJustAddedNodes fails on my Mac
because it waits for the default connection timeout of 30 seconds to connect to
a fake node with IP address 0.0.0.0. This connection attempt fails much more
quickly on Linux so the test passes.
This commit fixes this by reducing the connection timeout for this test.
Unlike index operations which can fail at the document level to
analyzing errors, delete operations should never fail at the document
level whether soft-deletes is enabled or not. With this change, we will
always fail the engine if we fail to apply a delete operation to Lucene.
Closes#33256
We currently convert pipeline aggregators to their corresponding
InternalAggregation instance as part of the final reduction phase.
They arrive to the coordinating node as part of QuerySearchResult
objects fom the shards and, despite we may incrementally reduce
aggs (hence we may have some non-final reduce and the final
one later) all the reduction phases happen on the same node.
With CCS minimizing roundtrips though, each cluster performs its
own non-final reduction, and then serializes the results back to
the CCS coordinating node which will perform the final coordination.
This breaks the assumptions made up until now around reductions
happening all on the same node.
With #40101 we have made sure that top-level pipeline aggs are not
reduced as part of the non-final reduction. The next step is to make
sure that they don't get lost, meaning that each coordinating node
needs to send them back to the CCS coordinating node as part of
the top-level `InternalAggregations` object.
Closes#40059
Today a coordinating node forces a final reduction of sibling pipeline aggregators whenever reducing aggs, unless it is reducing aggs incrementally. This works well for incremental reduction of aggs, but breaks CCS when minimizing roundtrips as each cluster ends up reducing its own pipeline aggregators locally while that should only be done by the CCS coordinating node later. This causes issues as after their reduction, pipeline aggs cannot be further reduced, which is what happens with CCS causing errors like "java.lang.UnsupportedOperationException: Not supported" being returned.
Each coordinating node should rather honour the reduce context flag that
indicates whether we are executing a final reduce or not. If not, it should leave the sibling pipeline aggregations alone.
Note that his bug affects only pipeline aggs that don't have a parent in
the aggs tree, while all the others work well.
Relates to #40059 but does not fix it yet, as the CCS coordinating node also needs to be adapted to recreate sibling pipeline aggregators from the request.
When minimizing round-trips, each cluster returns its own independent
search response. In case sort by field and/or field collapsing were
requested, when one cluster has no results to return, the information
about the field that sorting was based on (SortField array) as well as
the field (and the values) that collapsing was performed on are missing
in the search response. That causes problems as we can't build the
proper `TopDocs` instance which would need to be either `TopFieldDocs`
or `CollapseTopFieldDocs`. The merge routine expects that all the top
docs are of the same exact type which can't be guaranteed. Given that
the problematic results are empty, hence have no impact on the final
results, we can simply skip them.

When using DFS_QUERY_THEN_FETCH search type, the dfs phase is run and
its results are used in the query phase to make scoring accurate.
When using CCS, depending on whether the DFS phase runs in the CCS
coordinating node (like if all shards were local) or in each remote
cluster (when minimizing round-trips), scoring will differ.
This commit disables minimizing round-trips whenever DFS is requested,
as it is not currently possible to ensure that scoring is accurate in
that case.

When a node is repurposed to master/no-data or no-master/no-data, v7.x

The cache used in linearizability checker now uses approximately 6x less
memory by changing the cache from a set of (bits, state) tuples into a
map from bits -> { state }.
Each combination of states is kept once only, building on the
assumption that the number of state permutations is small compared to
the number of bits permutations. For those histories that are difficult
to check we will have many bits combinations that use the same state
permutations.
We end up now using approximately 15 bytes per entry compared to 101
bytes before, ie. a 6x improvement, allowing us to linearizability check
significantly longer histories.
Re-enabled linearizability checker in CoordinatorTests, hoping above
ensures we no longer run out of memory.

This PR introduces AsyncRecoveryTarget which executes remote calls of

This change adds a wrapper for IndexSearcher that makes IndexSearcher#search(List, Weight, Collector) visible by
sub-classes. The wrapper is used by the ContextIndexSearcher to call this protected method on a searcher created by a plugin.
This ensures that an override of the protected method in an IndexSearcherWrapper plugin is called when a search is executed.

This change adds an option to the `FieldSortBuilder` that allows to transform the type
of a numeric field into another. Possible values for this option are `long` that transforms
the source field into an integer and `double` that transforms the source field into a floating point.
This new option is useful for cross-index search when the sort field is mapped differently on some
indices. For instance if a field is mapped as a floating point in one index and as an integer in another
it is possible to align the type for both indices using the `numeric_type` option:
```
{
"sort": {
"field": "my_field",
"numeric_type": "double" <1>
}
}
```
<1> Ensure that values for this field are transformed to a floating point if needed.
This commit removes the cluster state size field from the cluster state
response, and drops the backwards compatibility layer added in 6.7.0 to
continue to support this field. As calculation of this field was
expensive and had dubious value, we have elected to remove this field.
Currently, we maintain a transport name ("mock-nio", "nio", "netty")
that is passed to a `TcpTransportChannel` when a request is received.
The value of this name is to associate with the task when we register a
task with the task manager. However, it is only possible to run ES with
one transport, so having an implementation specific name is unnecessary.
This commit removes the name and replaces it with the generic
"transport".
The `sampler` agg creates a BestDocsDeferringCollector, which internally
initializes a priority queue of size `shardSize`. This queue is
populated with empty `Object` sentinels, which is roughly 16b per
object.
Similarly, the Diversified samplers create a DiversifiedTopDocsCollectors
which internally track PQ slots with ScoreDocKeys, weighing in around
28kb
If the user sets a very abusive `shard_size`, this could easily OOM
a node or cluster since these PQ are allocated up-front without
any checks.
This commit makes sure that when we create the collector, it
cannot be larger than the maxDoc so that we don't accidentally blow
up the node. We ensure the size is not greater than the overall
index maxDoc. A similar treatment is done for `maxDocsPerValue`
parameter of the diversified samplers
For good measure, this also adds in some CB accounting to try and track
memory usage.
Finally, a redundant array creation is removed to reduce a bit of
temporary memory.
We call `ensureConnections()` to undo the effects of a disruption. However, it
is possible that one or more targets are currently CONNECTING and have been
since the disruption was active, and that the connection attempt was thwarted
by a concurrent disruption to the connection. If so, we cannot simply add our
listener to the queue because it will be notified when this CONNECTING activity
completes even though it was disrupted. We must therefore wait for all the
current activity to finish and then go through and reconnect to any missing
nodes.
Closes#40030.
Today we load the shard history retention leases from disk whenever opening the
engine, and treat a missing file as an empty set of leases. However in some
cases this is inappropriate: we might be restoring from a snapshot (if the
target index already exists then there may be leases on disk) or
force-allocating a stale primary, and in neither case does it make sense to
restore the retention leases from disk.
With this change we write an empty retention leases file during recovery,
except for the following cases:
- During peer recovery the on-disk leases may be accurate and could be needed
if the recovery target is made into a primary.
- During recovery from an existing store, as long as we are not
force-allocating a stale primary.
Relates #37165
Today we test Zen1/Zen2 compatibility by running 7.x nodes with a "fake" Zen1
implementation. However this is not a truly faithful test because these nodes
do known how to properly deserialize a 7.x cluster state, voting configurations
and all, whereas a real Zen1 node is in 6.7 and ignores the coordination
metadata.
We only ever apply a cluster state that's been committed, which in Zen2
involves setting the last-committed configuration to equal the last-accepted
configuration. Zen1 knows nothing about this adjustment, so it is possible for
these to differ. This breaks the assertion that the cluster states are equal on
all nodes after integration tests.
This commit fixes this by implementing this adjustment in Zen1 before applying
a cluster state.
Fixes#40055.
This change ensures that we do not make assumptions about the length

* Handle UTF8 values in the keystore
Our current implementation uses CharBuffer#array to get the chars
that were decoded from the UTF-8 bytes. The backing array of
CharBuffer is created in CharsetDecoder#decode and gets an initial
length that is the same as the length of the ByteBuffer it decodes,
hence the number of UTF-8 bytes.
This works fine for the first 128 characters where each one needs
one bytes, but for the next UTF-8 characters (other latin alphabets
Greek, Cyrillic etc.) where we need 2 to 4 bytes per character, this
backing char array has a larger size than the number of the actual
chars this CharBuffer contains. Calling `array()` on it will return
a char array that can potentially have extra null chars so the
SecureString we get from the KeystoreWrapper, is not the same as the
one we entered.
This commit changes the behavior to use Arrays#copyOfRange to get
the necessary chars from the CharBuffer and adds a test with
random ( maybe not printable ) UTF-8 strings
Computing the compressed size of the cluster state on every invocation
of cluster:monitor/state action is expensive, and the value of this
field is dubious anyway. Therefore we want to remove computing this
field. As a first step, we stop computing and return this field by
default. To avoid breaking users, we will give them a system property to
use to tide them over until the next major release when we will actually
remove this field. This comes with a deprecation warning too, and the
backport to the appropriate minor will also include a note in the
migration guide. There will be a follow-up to remove this field in the
next major version.
After the joda-java time migration we were formatting zone ids with zoneOrOffsetId method. This when a date was provided with a ZoneRegion for instance America/Edmonton it was appending this zone identifier instead of zone formatted as +HH:MM.

Currently token filter settings are treated as fixed once they are declared and
used in an analyzer. This is done to prevent changes in analyzers that are already
used actively to index documents, since changes to the analysis chain could
corrupt the index. However, it would be safe to allow updates to token
filters at search time ("search_analyzer"). This change introduces a new
property of token filters that allows to mark them as only being usable at search
or at index time. Any analyzer that uses these tokenfilters inherits that property
and can be rejected if they are used in other contexts. This is a first step towards
making specific token filters (e.g. synonym filter) updateable.

Today, when applying new cluster state we attempt to connect to all of its
nodes as a blocking part of the application process. This is the right thing to
do with new nodes, and is a no-op on any already-connected nodes, but is
questionable on known nodes from which we are currently disconnected: there is
a risk that we are partitioned from these nodes so that any attempt to connect
to them will hang until it times out. This can dramatically slow down the
application of new cluster states which hinders the recovery of the cluster
during certain kinds of partition.
If nodes are disconnected from the master then it is likely that they are to be
removed as part of a subsequent cluster state update, so there's no need to try
and reconnect to them like this. Moreover there is no need to attempt to
reconnect to disconnected nodes as part of the cluster state application
process, because we periodically try and reconnect to any disconnected nodes,
and handle their disconnectedness reasonably gracefully in the meantime.
This commit alters this behaviour to avoid reconnecting to known nodes during
cluster state application.
Resolves#29025.
If a primary on 6.7 and a replica on 5.6 are running more than 5 minutes

background sync will be triggered, and it will trip 6.7 node due to the

checkpoint depends on the node version. This PR, however, chooses to
enforce retention leases require soft deletes, and make retention leases
sync noop if soft deletes is disabled instead.

the request to the "7" index.
Additionally, to due to a difference in the internal representation

(which requires the exclusion of any type) a helper method is introduced
to help convert internal to external representation, and used by the
monitoring HTTP template exporter.

Executors of type fixed_auto_queue_size (i.e. search / search_throttled) wrap runnables into
TimedRunnable, which is an AbstractRunnable. This is dangerous as it might silently swallow
exceptions, and possibly miss calling a response listener. While this has not triggered any failures in
the tests I have run so far, it might help uncover future problems.
Follow-up to #36137
This test started failing since decreasing the leader and follower check timeouts (#38298). The

Currently we log exceptions due to channel close at the debug level in
the normal exception handler. Currently we log all send failures due to
channel close at the warn level. This commit changes that to only log at
warn if the send failure is not due to channel closed. Additionally, it
adds the ssl engine closed as a channel close exception.
Today we use a ConcurrentHashSet to track the in-flight outgoing joins in the
`JoinHelper`. This is fine for adding and removing elements but not for the
emptiness test in `isJoinPending()` which might return false if one join
finishes just after another one starts, even though joins were pending
throughout.
As used today this is ok: it means the node was trying to join a master but
this join attempt just finished unsuccessfully, and causes it to (rightfully)
reject a `FollowerCheck` from the failed master. However this kind of API
inconsistency is trappy and there is no need to be clever here, so this change
replaces the set with a `synchronizedSet()`.
When ESRejectedExecutionException gets thrown on the coordinating node while trying to fetch hits, the resulting exception will hold no shard failures, hence `503` is used as the response status code. In that case, `429` should be returned instead. Also, the status code should be taken from the cause if available whenever there are no shard failures instead of blindly returning `503` like we currently do.
Closes#38586
The monitoring bulk API accepts the same format as the bulk API, yet its concept
of types is different from "mapping types" and the deprecation warning is only
emitted as a side-effect of this API reusing the parsing logic of bulk requests.
This commit extracts the parsing logic from `_bulk` into its own class with a
new flag that allows to configure whether usage of `_type` should emit a warning
or not. Support for payloads has been removed for simplicity since they were
unused.
@jakelandis has a separate change that removes this notion of type from the
monitoring bulk API that we are considering bringing to 8.0.
This commit propagates some exceptions that were previously swallowed and also
