Today the blended term query detects if a term exists in a field by looking at the term statistics in the index.
However the value to indicate that a term has no occurence in a field have changed in Lucene. A non-existing term now returns
a doc and total term frequency of 0. Because of this disrepancy the blended term query picks 0 as the minimum frequency for a term
even if other fields have documents for this terms. This confuses the term queries that the blending creates since some of them
contain a custom state that indicates a frequency of 0 even though the term has some occurence in the field. For these terms an exception
is thrown because the term query always checks that the term state's frequency is greater than 0 if there are documents associate to it.
This change fixes this bug by ignoring terms with a doc freq of 0 when the blended term query picks the minimum term frequency among the
requested fields.
Closes#41118
`TransportReplicationAction.AsyncPrimaryAction#createReplicatedOperation`
exists so it can be overridden in tests. This commit re-works these tests to
use a real `ReplicationOperation` and inlines the now-unnecessary method.
Relates #40706.
Today we fail to join a Zen2 cluster if the cluster UUID does not match our
own, but we do not perform the same validation when joining a Zen1 cluster.
This means that a Zen2 node will pass join validation and be added to a Zen1
cluster but will reject all cluster states from the master.

Currently we throw an error when a range querys minimum value exceeds the
maximum value due to the fact that they are neighbouring values and both upper
and lower value are excluded from the interval.
Since this is a condition that the user usually doesn't specify conciously (at
least in the case of float and double values its difficult to see which values
are adjacent) we should ignore those "wrong" intervals and create a
MatchNoDocsQuery in those cases.
We should still throw errors with an actionable message if the user specifies
the query interval in a way that min value > max value. This PR adds those
checks and tests for those cases.
Closes#40937
This is related to #36652. We intend to deprecate a number of transport
settings in 7.x and remove them in 8.0. This commit removes the string
usages of these settings.
Pipelines require single-valued agg or a numeric to be returned.
If they don't get that, they throw an exception. Unfortunately, this
exception text is very confusing to users because it usually arises
from pathing "through" multiple terms aggs. The final target is a numeric,
but it's the intermediary aggs that cause the problem.
This commit adds the current agg name to the exception message
so the user knows which "level" is the issue.
Full text queries ignore unmapped fields since https://github.com/elastic/elasticsearch/issues/41022
even if all fields in the query are unmapped.
This change makes sure that we ignore unmapped fields only if they are mixed
with mapped fields and returns a MatchNoDocsQuery otherwise.
Closes#41022
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

When a polygon contains a self-intersection due to have twice the same point in no-consecutive position, the polygon builder tries to split the polygon. During the split one of the polygons become invalid as it is not closed and an error is thrown which is not related to the real issue.
We detect this situation now and throw a more meaningful error.
Today a new replica of a closed index does not have a safe commit
invariant when its engine is opened because we won't initialize the
global checkpoint on a recovering replica until the finalize step. With
this change, we can achieve that property by creating a new translog
with the global checkpoint from the primary at the end of phase 1.
This helps avoid memory issues when computing deep sub-aggregations. Because it
should be rare to use sub-aggregations with significant terms, we opted to always
choose breadth first as opposed to exposing a `collect_mode` option.
Closes#28652.
Since #40249, we always reinitialize max_seq_no_of_updates to max_seq_no
when a promoting primary restores history regardless of whether it did
rollback previously or not.
Closes#40929
This commit removes the settings member variable from Node.
This member made it confusing which settings should actually be looked
at. Now all settings are accessed through the final environment.
A small refactoring that removes the primaryTerm field from ReplicasProxy and
instead passes it directly in to the methods that need it. Relates #40706.
This is a dependency of #39504
Motivation:
By refactoring `TransportShardBulkAction#shardOperationOnPrimary` to async, we enable using `DeterministicTaskQueue` based tests to run indexing operations. This was previously impossible since we were blocking on the `write` thread until the `update` thread finished the mapping update.
With this change, the mapping update will trigger a new task in the `write` queue instead.
This change significantly enhances the amount of coverage we get from `SnapshotResiliencyTests` (and other potential future tests) when it comes to tracking down concurrency issues with distributed state machines.
The logical change is effectively all in `TransportShardBulkAction`, the rest of the changes is then simply mechanically moving the caller code and tests to being async and passing the `ActionListener` down.
Since the move to async would've added more parameters to the `private static` steps in this logic, I decided to inline and dry up (between delete and update) the logic as much as I could instead of passing the listener + wait-consumer down through all of them.
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

It could be that we try to shutdown the executor pool before all the
listeners have been invoked. It can happen that one was not invoked if
it timed out and was in the process of being notified that it timed out
on the executor. If we do this shutdown then, a listener will be met
with rejected execution exception. To address this, we first wait until
all listeners have been notified (or timed out) before proceeding with
shutting down the executor.

Today if `cluster.routing.rebalance.enable: none` then rebalancing is disabled,
but we still execute `balanceByWeights()` and perform some rather expensive
calculations before discovering that we cannot rebalance any shards. In a large
cluster this can make cluster state updates occur rather slowly. With this
change we check earlier whether rebalancing is globally disabled and, if so,
avoid the rebalancing process entirely.
Relates #40942 which was reverted because of egregiously faulty tests.
The number of user data attributes of an index commit has increased
from 6 to 8, but we forgot to adjust. This change increases the initial
size of that map to avoid resizing.
Reducing some methods scope and marking them as static where possible. Removing
"alias" support from AnalysisRegistry#produceAnalyze and changing that method to
return a NamedAnalyzer instead of having a side effect on the analyzer map passed in.
Also, CustomAnalyzerProvider doesn't seem to need the `environment` field.

The phrase suggesters have an option to remove terms that have
a frequency lower than a provided min_doc_freq. However this value is
overwritten by the frequency of the original term in the popular mode.
This change ensures that we keep the maximum value between the provided
min_doc_value and the original term frequency as a threshold to select
candidates.
Fixes#16764
Today we are strict when parsing build flavor and types off the
wire. This means that if a later version introduces a new build flavor
or type, an older version would not be able to parse what that new
version is sending. For a practical example of this, we recently added
the build type "docker", and this means that in a rolling upgrade
scenario older nodes would not be able to understand the build type that
the newer node is sending. This breaks clusters and is bad. We do not
normally think of adding a new enumeration value as being a
serialization breaking change, it is just not a lesson that we have
learned before. We should be lenient here though, so that we can add
future changes without running the risk of breaking ourselves
horribly. It is either that, or we have super-strict testing
infrastructure here yet still I fear the possibility of mistakes. This
commit changes the parsing of build flavor and build type so that we are
still strict at startup, yet we are lenient with values coming across
the wire. This will help avoid us breaking rolling upgrades, or clients
that are on an older version.
If the transport service is stopped, likely because we are shutting
down, and a retention lease background sync fires the logs will display
a warn message and stacktrace. Yet, this situaton is harmless and can
happen as a normal course of business when shutting down. This commit
suppresses the log messages in this case.
The `getIndexShard()` and `sendReplicaRequest()` methods in
TransportReplicationAction are effectively only used to customise some
behaviour in tests. However there are other ways to do this that do not cause
such an obstacle to separating the TransportReplicationAction into its two
halves (see #40706).
This commit removes these customisation points and injects the test-only
behaviour using other techniques.
Many gradle projects specifically use the -try exclude flag, because
there are many cases where auto-closeable resource ignore is never
referenced in body of corresponding try statement. Suppressing this
warning specifically in each case that it happens using
`@SuppressWarnings("try")` would be very verbose.
This change removes `-try` from any gradle project and adds it to the
build plugin. Also this change removes exclude flags from gradle projects
that is already specified in build plugin (for example -deprecation).

Primary-replica resync in a mixed-cluster between 6.x and 5.6 can send
operations without sequence number to a replica which already processed
operations with sequence number. This leads to the failure of that
replica for we trip the sequence number assertion when writing resync
operations without sequence number to translog.
This change rejects an illegal combination of flush parameters where
force is true, but wait_if_ongoing is false. This combination is trappy
and should be forbidden.

If there's an ongoing flush triggered by the translog flush threshold,
we may fail to execute a flush because waitIfOngoing is false by

If a refresh, which is scheduled by the setting change, executes after
