Today in the method IOUtils#fsync we ignore IOExceptions when fsyncing a
directory. However, the catch block here is too broad, for example it
would be ignoring IOExceptions when we try to open a non-existant
file. This commit addresses that by scoping the ignored exceptions only
to the invocation of FileChannel#force.
Previously, a reindex request had two different size specifications in the body:
* Outer level, determining the maximum documents to process
* Inside the source element, determining the scroll/batch size.
The outer level size has now been renamed to max_docs to
avoid confusion and clarify its semantics, with backwards compatibility and
deprecation warnings for using size.
Similarly, the size parameter has been renamed to max_docs for
update/delete-by-query to keep the 3 interfaces consistent.
Finally, all 3 endpoints now support max_docs in both body and URL.

Today we assert that the connection thread is blocked by the time the test gets
to the barrier, but in fact this is not a valid assertion. The following
`Thread.sleep()` will cause the test to fail reasonably often.

Currently, when the SSLEngine needs to produce handshake or close data,
we must manually call the nonApplicationWrite method. However, this data
is only required when something triggers the need (starting handshake,
reading from the wire, initiating close, etc). As we have a dedicated
outbound buffer, this data can be produced automatically. Additionally,
with this refactoring, we combine handshake and application mode into a
single mode. This is necessary as there are non-application messages that
are sent post handshake in TLS 1.3. Finally, this commit modifies the
SSLDriver tests to test against TLS 1.3.
This is related to #31908. In order to use the external version in a
reindex from remote request, the search request must be configured to
request the version (as it is not returned by default). This commit
modifies the search request to request the version. Additionally, it
modifies our current reindex from remote tests to randomly use the
external version_type.
Changed order of listener invocation so that we notify before
registering search context and notify after unregistering same.
This ensures that count up/down like what we do in ShardSearchStats
works. Otherwise, we risk notifying onFreeScrollContext before notifying
onNewScrollContext (same for onFreeContext/onNewContext, but we
currently have no assertions failing in those).
Closes#28053
The test failed because we had only a single document in the index
that got deleted such that some assertions that expected at least
one live doc failed.

Single updates use a different internal code path than updates that are wrapped in a bulk request.
While working on a refactoring to bring both closer together I've noticed that bulk updates were
failing some of the tests that single updates passed. In particular, bulk updates cause
NullPointerExceptions to be thrown and listeners not being properly notified when being rejected
from the thread pool.
This change adds a merge policy that drops all _id postings for documents that
are marked as soft-deleted but retained across merges. This is usually unnecessary
unless soft-deletes are used with a retention policy since otherwise a merge would
remove deleted documents anyway.
Yet, this merge policy prevents extreme cases where a very large number of soft-deleted
documents are retained and are impacting update performance.
Note, using this merge policy will remove all lookup by ID capabilities for soft-deleted documents.
A static code analysis revealed that we are not closing
the input stream in the find_file_structure endpoint.
This actually makes no difference in practice, as the
particular InputStream implementation in this case is
org.elasticsearch.common.bytes.BytesReferenceStreamInput
and its close() method is a no-op. However, it is good
practice to close the stream anyway.
This change adds the earliest and latest timestamps into
the field stats for fields of type "date" in the output of
the ML find_file_structure endpoint. This will enable the
cards for date fields in the file data visualizer in the UI
to be made to look more similar to the cards for date
fields in the index data visualizer in the UI.
increases the scheduler interval to fire less frequently, namely changing it from 1s to 10s. The scheduler interval is used for retrying after an error condition.
Adds a metadata field to snapshots which can be used to store arbitrary
key-value information. This may be useful for attaching a description of
why a snapshot was taken, tagging snapshots to make categorization
easier, or identifying the source of automatically-created snapshots.
The `replace` option in the phonetic token filter can have suprising side
effects, e.g. such as described in #26921. This PR adds a note to be mindful
about such scenarios and offers alternatives to using the `replace` option.

Some clusters might have been already migrated to version 7 without being warned about the joda-java migration changes.
Deprecation api on that version will give them guidance on what patterns need to be changed.
relates. This change is using the same logic like in 6.8 that is: verifying the pattern is from the incompatible set ('y'-Y', 'C', 'Z' etc), not from predifined set, not prefixed with 8. AND was also created in 6.x. Mappings created in 7.x are considered migrated and should not generate warnings
There is no pipeline check (present on 6.8) as it is impossible to verify when the pipeline was created, and therefore to make sure the format is depracated or not
#42010
This change abstracts the specific types away from the different
representations of datetime as a datetime representation in code can be all
kinds of different things. This defines the three most common types of
datetimes as numeric, string, and complex while outlining the type most
typically used for these as long, String, and ZonedDateTime, respectively.
Documentation uses the definitions while examples use the types. This makes
the documentation easier to consume especially for people from a non-Java
background.

This commit disables building on JDK 13 in CI. The reason for this is
because Gradle is not yet ready to run on JDK 13. We could re-introduce
infrastructure to enable Gralde to run on a different JDK than the build
JDK, but rather than introducing such complexity we will instead wait
for Gradle to be ready to run on JDK 13.
Dots in the column names cause an error in the ingest
pipeline, as dots are special characters in ingest pipeline.
This PR changes dots into underscores in CSV field names
suggested by the ML find_file_structure endpoint _unless_
the field names are specifically overridden. The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots. But it's
more consistent that the default behaviour is to replace
them all.

The full-text query parsers accept field pattern that are expanded using the mapping.
Alias field are also detected during the expansion but they are not deduplicated with the
concrete fields that are found from other patterns (or the same). This change ensures
that we deduplicate the target fields of the full-text query parsers in order to avoid
adding the same clause multiple times. Boolean queries are already able to deduplicate
clauses during rewrite but since we also use DisjunctionMaxQuery it is preferable to detect
these duplicates early on.
This change makes use of the reader attributes added in LUCENE-8671
to ensure that `_id` fields are always on-heap for best update performance
and term dicts are generally off-heap on Read-Only engines.

This test is failing because recoveries of these empty shards are not
completing in a reasonable time, but the reason for this is still obscure. This

This commit adds functionality so that aliases that are manipulated on
leader indices are replicated by the shard follow tasks to the follower
indices. Note that we ignore write indices. This is due to the fact that
follower indices do not receive direct writes so the concept is not
useful.

This commit fixes the version parsing in various tests. The issue here is that
the parsing was relying on java.version. However, java.version can contain
additional characters such as -ea for early access builds. See JEP 233:
Name Syntax
------------------------------ --------------
java.version $VNUM(\-$PRE)?
java.runtime.version $VSTR
java.vm.version $VSTR
java.specification.version $VNUM
java.vm.specification.version $VNUM
Instead, we want java.specification.version.
