When a query contains a mandatory clause that doesn't track the max score per
block, we disable the max score optimization. Previously, we were doing this by
wrapping the collector with a FilterCollector that always returned
ScoreMode.COMPLETE.
However we weren't adjusting totalHitsThreshold, so the collector could still
call Scorer#setMinCompetitiveScore. It is against the method contract to call
setMinCompetitiveScore when the score mode is COMPLETE, and some scorers like
ReqOptSumScorer throw an error in this case.
This commit tries to disable the optimization by always setting
totalHitsThreshold to max int, as opposed to wrapping the collector.

Today we might carry on a big merge uncommitted and therefore
occupy a significant amount of diskspace for quite a long time
if for instance indexing load goes down and we are not quickly
reaching the translog size threshold. This change will cause a
flush if we hit a significant merge (512MB by default) which
frees diskspace sooner.
We only sync translog if the given offset hasn't synced yet. We can't
verify the global checkpoint from the latest translog checkpoint unless
a sync has occurred.

If a CCR lease is disappeared while we are renewing it, then we will
issue asyncAddRetentionLease to add that lease. And if
asyncAddRetentionLease takes longer than retentionLeaseRenewInterval,
then we can issue another asyncAddRetentionLease request. One of
asyncAddRetentionLease requests will fail with
RetentionLeaseAlreadyExistsException, hence trip the assertion.
Closes#45192
Today the `DiskThresholdDecider` attempts to account for already-relocating
shards when deciding how to allocate or relocate a shard. Its goal is to stop
relocating shards onto a node before that node exceeds the low watermark, and
to stop relocating shards away from a node as soon as the node drops below the
high watermark.
The decider handles multiple data paths by only accounting for relocating
shards that affect the appropriate data path. However, this mechanism does not
correctly account for _new_ relocating shards, which are unwittingly ignored.
This means that we may evict far too many shards from a node above the high
watermark, and may relocate far too many shards onto a node causing it to blow
right past the low watermark and potentially other watermarks too.
There are in fact two distinct issues that this PR fixes. New incoming shards
have an unknown data path until the `ClusterInfoService` refreshes its
statistics. New outgoing shards have a known data path, but we fail to account
for the change of the corresponding `ShardRouting` from `STARTED` to
`RELOCATING`, meaning that we fail to find the correct data path and treat the
path as unknown here too.
This PR also reworks the `MockDiskUsagesIT` test to avoid using fake data paths
for all shards. With the changes here, the data paths are handled in tests as
they are in production, except that their sizes are fake.
Fixes#45177
This commit removes the usage of MockAmazonS3 in S3BlobStoreRepositoryTests
and replaces it by a HttpServer that emulates the S3 service. This allows the
repository tests to use the real Amazon's S3 client under the hood in tests and will
allow to test the behavior of the snapshot/restore feature for S3 repositories by
simulating random server-side internal errors.
The HTTP server used to emulate the S3 service is intentionally simple and minimal
to keep things understandable and maintainable. Testing full client options on the
server side (like authentication, chunked encoding etc) remains the responsibility
of the AmazonS3Fixture.
AbstractSimpleTransportTestCase.testTransportProfilesWithPortAndHost
expects a host to only have a single IPv4 loopback address, which isn't
necessarily the case. Allow for >= 1 address.

The _cat/health call in getting-started assumes that the master task max
wait time is always 0 (-), however, the test could sometimes run into a
short wait time (like some ms). Fixed to allow this.
Today we assume that document failures can not occur for deletes. This
assumption is bogus, as they can fail for a variety of reasons such as
the Lucene index having reached the document limit. Because of this
assumption, we were asserting that such a document-level failure would
never happen. When this bogus assertion is violated, we fail the node, a
catastrophe. Instead, we need to treat this as a fatal engine exception.
We currently configure io.netty.allocator.numDirectArenas to be 0 in the
jvm erconomics class. This is a config that we always want to set, so it
makes sense to move it to jvm.options.
This commit adds the `rollover_alias` setting required for ILM to work
correctly to the SLM history index template and adds assertions to the
SLM integration tests to ensure that it works correctly.
Currently, when using script_score functions like cosineSimilarity, the query
vector is treated as an array of doubles. Since the stored document vectors use
floats, it seems like the least surprising behavior for the query vectors to
also be float arrays.
In addition to improving consistency, this change may help with some
optimizations we have been considering around vector dot product.

While the plugin installation directory used to be settable, it has not
been so for several major versions. This commit removes a lingering
reference to the plugins directory in upgrade docs.

Add XContentType as parameter to the
AbstractResponseTestCase#createServerTestInstance method.
In the case a server side response class serializes xcontent as
bytes then the test needs to know what xcontent type was randomily selected.
This change is needed in #45970

* Add support for a Range field ValuesSource, including decode logic for range doc values and exposing RangeType as a first class enum
* Provide hooks in ValuesSourceConfig for aggregations to control ValuesSource class selection on missing & script values
* Branch aggregator creation in Histogram and DateHistogram based on ValuesSource class, to enable specialization based on type. This is similar to how Terms aggregator works.
* Prioritize field type when available for selecting the ValuesSource class type to use for an aggregation
This commit adds support for `boolean` fields in data frame
analytics (and currently both outlier detection and regression).
The analytics process expects `boolean` fields to be encoded as
integers with 0 or 1 value.
Prior to this commit the foreach action execution had a hard coded
limit to 100 iterations. This commit allows the max number of
iterations to be a configuration ('max_iterations') on the foreach
action. The default remains 100.
Currently the process to execute a reindex process is tightly coupled to
step of initializing the task state. This creates problems when this
process is asynchronous. It is possible that the task state has not been
initialized which prevents follow-up actions such as rethrottle. This
commit separates the task initialization so that it can be executed as a
first step in the persistent reindex process.
This commit extracts the reindexing logic from the transport action so
that it can be incorporated into the persistent reindex work without
requiring the usage of the client.
Currently we use a custom CopyBytesSocketChannel for interfacing with
netty. We have integration tests that use this channel, however we never
verify the read and write behavior in the face of potential partial
writes. This commit adds a test for this behavior.
