Although we allow to index BigInteger and BigDecimal into a keyword
field, source filtering on these fields would fail
as XContentBuilder was not able to deserialize BigInteger and BigDecimal
to json.
This modifies XContentBuilder to allow to handle BigInteger and
BigDecimal.
Closes#32395
This commits creates a DateMathParser interface, which is already
implemented for both joda and java time. While currently the java time
DateMathParser is not used, this change will allow a followup which will
create a DateMathParser from a DateFormatter, so the caller does not
need to know the internals of the DateFormatter they have.
Previously, unmapped aggs try to delegate reduction to a sibling agg that is
mapped. That delegated agg will run the reductions, and also
reduce any pipeline aggs. But because delegation comes before running
pipelines, the unmapped agg _also_ tries to run pipeline aggs.
This causes the pipeline to run twice, and potentially double it's output
in buckets which can create invalid JSON (e.g. same key multiple times)
and break when converting to maps.
This fixes by sorting the list of aggregations ahead of time so that mapped
aggs appear first, meaning they preferentially lead the reduction. If all aggs
are unmapped, the first unmapped agg simply creates a new unmapped object
and returns that for the reduction.
This means that unmapped aggs no longer defer and there is no chance for
a secondary execution of pipelines (or other side effects caused by deferring
execution).
Closes#33514
`SingleFieldsVisitor` is meant to load a single stored field but it
manages to be quite complex to reason about because it inherits from our
"basic" `FieldsVisitor` which is designed to load many fields. This
breaks that inheritance and adds logic to `SingleFieldsVisitor` so it can
be properly stand alone. While this amounts to more lines of code they
ought to be significantly easier to reason about.
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
This commit removes the sysprop controlling whether ctx is in params for
update scripts and replaces it with use of the new ParameterMap, which
outputs a deprecation warning whenever params.ctx is used.
Today query parsers throw TooManyClauses exception when a query creates
too many clauses. However graph phrase queries do not respect this limit.
This change adds a protection against crazy expansions that can happen when
building a graph phrase query. This is a temporary copy of the fix available
in https://issues.apache.org/jira/browse/LUCENE-8479 but not merged yet.
This logic will be removed when we integrate the Lucene patch in a future
release.

Today `SearchAsyncActionTests#testFanOutAndCollect` uses a simple `HashMap` for
the `nodeToContextMap` variable, which is then accessed from multiple threads
without, apparently, explicit synchronisation. This provides an explanation for
the test failure identified in #29242 in which `.toString()` returns `"[]"`
just before `.isEmpty` returns `false`, without any concurrent modifications.
This change converts `nodeToContextMap` to a `newConcurrentMap()` so that this
cannot occur. It also fixes a race condition in the detection of double-calling
the subsequent search phase.
Closes#29242.
We start tracking max seq_no_of_updates on the primary in #33842. This
commit replicates that value from a primary to its replicas in replication
requests or the translog phase of peer-recovery.
With this change, we guarantee that the value of max seq_no_of_updates
on a replica when any index/delete operation is performed at least the
max_seq_no_of_updates on the primary when that operation was executed.

We currently fallback to local indices whenever a remote cluster is not found, as there may still be indices / aliases with the same name. Such behaviour is lenient but needs to be kept for backwards compatibility. Clarified that in the code so we don't forget.

It mistakenly uses the Elasticsearch major version instead of the Lucene major
version. I noticed it when backporting, it is not noticeable on master because
the only two Lucene versions that are supported, 7 and 8, encode norms the same
way, unlike Lucene 6.
Today, TransportService uses System.currentTimeMillis() to get the current time
to report on things like timeouts, and enqueues lambdas for future execution.
However, in tests it is useful to be able to fake out the current time and to
see what all these enqueued lambdas are really for. This change alters the
situation so that we can obtain the time from the more easily-faked
ThreadPool#relativeTimeInMillis(), and implements some friendlier toString()
methods on the various Runnables so we can see what they are later.
As far as I can tell this guard against fragile analyzers is no longer relevant, since
we stopped setting special analyzers on numeric fields (3bf6f4). Instead of removing
the guard completely, I opted to keep a check for untokenized + unnormalized fields
to avoid going through the analysis process unnecessarily.
My motivation for simplifying this check is that I'd like to add support for
`split_queries_on_whitespace` to the new 'queryable object' fields. As it stands, I would
have to add a dedicated instanceof check for the new mapper, which is not optimal.
This commit introduces an AbstractSimpleSecurityTransportTestCase for
security transports. This classes provides transport tests that are
specific for security transports. Additionally, it fixes the tests referenced in
#33285.
* 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.
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.
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.

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.
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.

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.
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.
With this commit we clear the fielddata cache per field as it is
supposed to be. Previously we retrieved the proper field from the cache
but then cleared the entire cache anyway.
