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.

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.
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.

This change adds "contains" method to LocalCheckpointTracker.
One of the use cases is to check if a given operation has been processed
in an engine or not by looking up its seq_no in LocalCheckpointTracker.
Relates #33656
In cases when mixed secure S3 client credentials and insecure S3 client
credentials were used (that is, those defined on the repository), we
were overriding the credentials from the repository using insecure
settings to all the repositories. This commit fixes this by not mixing
up repositories that use insecure settings with those that use secure
settings.
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
With the upcoming instance bindings, the singular *Binding name isn't descriptive enough
with multiple binding types. This renames the existing *Binding classes to *ClassBinding.
Mechanical change (with some error messages changed from binding to class binding by
hand).
By moving CompletionStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibiltiy out of IndexShard
which has quiet some complexity already.
Relates to #33835
Today if we fetch common stats from a shard we might get a partial response
if the shard is closed while we fetch the stats. This causes hard to track and
reproduce NPEs. This change streamlines null checking to ensure we only render
stats we actually received.
Wraps all lines in our test framework at 140 characters because that is
our standard line length and removes all of the checkstyle suppressions
for the test framework.
Drops most of `ModuleTestCase` because it isn't used and we're moving
away from using guice in the way that it wants to test anyway. Also
switches a few classes that extend it but don't use it to extend
`ESTestCase` instead.
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.
This commit adds two methods to the TokenFilterFactory interface.
* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
`CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
list `Analyzer`. By default it returns `true`.
Fixes#33609
This test occasionally fails in `testCollectSearchShards` waiting on what seems
to be a search request to a remote cluster for one second. Given that the test
fails here very rarely I suspect maybe one second is very rarely not enough so
we could fix it by increasing the max wait time slightly.
Closes#33852
By moving DocStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibility out of IndexShard
which has quiet some complexity already.
The documentation currently tells users to use `doc['event_date'].value.getMillis` to access
milliseconds in a date. It turns out the way it works is `doc['event_date'].value.millis`. This
change corrects this and gives a hint at how other date related methods work.
The fix in #33757 introduces some workaround since FilterCodecReader didn't
support unwrapping. This cuts over to a more elegant fix to access the readers
segment infos.
Previously multiple comma separated lists of options where not
recognized correctly which resulted in only the last of them
to be taked into account, e.g.:
For the following query:
SELECT * FROM test WHERE QUERY('search', 'default_field=foo', 'default_operator=and')"
only the `default_operator=and` was finally passed to the ES query.
Fixes: #32602
It is not obvious that a filesystem-level backup may capture an inconsistent
set of files that may fail on restore, or (worse) succeed having silently
discarded some data. This change spells the out, and reorganises the first page
or so of the snapshot/restore docs to make this warning fit more nicely.
