* TESTS: Make score Float#NaN when there is no max score
Fixes test failure due to maxScore set to Float#MinValue instead
on Float#NaN. In addition the initial value for maxScore is set to
Float#NEGATIVE_INFINITY so it is an illegal value.
Closes#33993
When executing a cross-cluster search, we need to search against all local indices (and no remote indices) in case no indices are specified. Also, if only remote indices are specified, no local indices will be queried. We previously added empty local indices whenever they were not present in the map of the grouped indices, then we would act differently later based on the extracted remote indices. Instead, we now add the empty array for local indices only in case we need to search all local indices; the entry for local indices is not added when local indices should not be searched. This way the grouped indices reflect reality and provide a better indication of what indices will be searched.
The source only snapshot drops fully deleted segments before snapshotting
them. In order to compare them we need to drop all fully deleted segments
in the test as well.
Closes#33755
Settings validation in AutoQueueAdjustingExecutorBuilder always checked against
a default value which means that we never can change a max queue size that is lower
than the default. This change adds tests and fixes this validation.
If numWrites is between 2 and 9, we will issue an invalid range because
the from_seq_no is negative. This commit makes sure that numWrites is at
least 10, and adds an explicit test to verify invalid request ranges.
SearchGroupsResolverInMemoryTests was (rarely) fail in a way that
suggests that the server-side delay (100ms) was not enough to trigger
the client-side timeout (5ms).
The server side delay has been increased to try and overcome this.
Resolves: #32913
Previously numeric values in the field_stats created by the
find_file_structure endpoint were always output with a
decimal point. This looked unfriendly and unnatural for
fields that clearly store integer values. This change
converts integer values to type Integer before output in
the file structure field stats.
This PR is the first step to use seq_no to optimize indexing operations.
The idea is to track the max seq_no of either update or delete ops on a
primary, and transfer this information to replicas, and replicas use it
to optimize indexing plan for index operations (with assigned seq_no).
The max_seq_no_of_updates on primary is initialized once when a primary
finishes its local recovery or peer recovery in relocation or being
promoted. After that, the max_seq_no_of_updates is only advanced internally
inside an engine when processing update or delete operations.

* Add commented out JVM options for G1GC
These options are available now that we will be supporting G1GC for Java 10 and
above. They are also designed so that the CMS options don't have to be commented
out in order for the G1 options to take effect.
* Update wording
This commit reverts most of #33157 as it introduces another race
condition and breaks a common case of watcher, when the first watch is
added to the system and the index does not exist yet.
This means, that the index will be created, which triggers a reload, but
during this time the put watch operation that triggered this is not yet
indexed, so that both processes finish roughly add the same time and
should not overwrite each other but act complementary.
This commit reverts the logic of cleaning out the ticker engine watches
on start up, as this is done already when the execution is paused -
which also gets paused on the cluster state listener again, as we can be
sure here, that the watches index has not yet been created.
This also adds a new test, that starts a one node cluster and emulates
the case of a non existing watches index and a watch being added, which
should result in proper execution.
Closes#33320
This change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.
* Setting SO_LINGER for open but not connected non-blocking sockets
throws on OSX
* Fixed by only applying setting to connected sockets which will save
the same number of FDs as doing it on open sockets anyway
* closes#33879
Today we don't store the auto-generated timestamp of append-only
operations in Lucene; and assign -1 to every index operations
constructed from LuceneChangesSnapshot. This looks innocent but it
generates duplicate documents on a replica if a retry append-only
arrives first via peer-recovery; then an original append-only arrives
via replication. Since the retry append-only (delivered via recovery)
does not have timestamp, the replica will happily optimizes the original
request while it should not.
This change transmits the max auto-generated timestamp from the primary
to replicas before translog phase in peer recovery. This timestamp will
prevent replicas from optimizing append-only requests if retry
counterparts have been processed.

Currently, assertSeqNos assumes that the cluster is stable at the end of
the test (i.e., no more shard movement). However, this assumption does
not always hold. In these cases, we can stop the assertion instead of
failing a test.
Closes#33704
If a shard was serving as a replica when another shard was promoted to
primary, then its Lucene index was reset to the global checkpoint.
However, if the new primary fails before the primary/replica resync
completes and we are now being promoted, we have to restore the reverted
operations by replaying the translog to avoid losing acknowledged writes.

It's possible for the set "seqNos" to contain only the "unFinishedSeq"
in the testConcurrentReplica test. If this is the case, the call
`randomValueOtherThan` won't make any progress because the predicate
will never be false.
This commit removes this expectation because it's incorrect and it's no
longer needed as we have a dedicated test to verify the contains method.
Relates #33871
The job deletion logic was scattered around a few places:
the transport action, the job manager and the deletion task.
Overloading the task with deletion logic also meant extra
dependencies in the core package which should be unnecessary.
This commit consolidates all this logic into the transport action
and replaces the deletion task with a plain one that needs not be
aware of deletion logic.
Drops `Settings` from some of the methods to lookup loggers and
deprecates another logger lookup that takes `Settings` because
`Settings` is no longer required to build a logger.
* ingest: support simulate with verbose for pipeline processor
This change better supports the use of simulate?verbose with the
pipeline processor. Prior to this change any pipeline processors
executed with simulate?verbose would not show all intermediate
processors for the inner pipelines.
This changes also moves the PipelineProcess and TrackingResultProcessor
classes to enable instance checks and to avoid overly public classes.
As well this updates the error message for when cycles are detected
in pipelines calling other pipelines.
The high level Rest clients reindex method currently doesn't pass on the
"requests_per_second" that are optionally set in ReindexRequest through the Rest
layer. This change makes sure the value is added to the request parameters if
set and also includes it for the update-by-query and delete-by-query cases.
* Added TRUNCATE function, modified ROUND to accept two parameters instead of one. Made the second parameter optional for both functions.
* Added documentation for both functions.
Removed rules in the grammar that were superfluous, as they
are already "caught" other rules in the same context.
Also switched to exact ambig detection for debug mode
Fixes: #31885
Today all searches happen on the search threadpool which is the correct
behavior in almost any case. Yet, there are exceptions where for instance
searches searches should be passed through a single-thread
thread-pool to reduce impact on a node. This change adds a index-private setting that allows to mark an index as throttled for searches and forks off all non-stats searcher access to this thread-pool for indices that are marked as `index.search.throttled`
Transient settings override persistent settings, but in fact all of the tests
that run as part of `:server:test` and `:server:integTest` will pass if the
precedence is changed to be the other way round. This change adds a test that
verifies the precedence is as documented.
