This is a follow up to #27695. This commit adds a test checking that
across multiple writes using multiple buffers, a write operation
properly keeps track of which buffers still need to be written.
It's possible that a merge may be ongoing when we check the breaker and segment
stats' memory usage, this causes the test to fail. Instead, we should wait for
merging to complete.
Resolves#27651
This test periodically fails if the nodes that apply the cluster state fail to ack the change within 100ms. This commit changes the checks on the test so that
it still checks that the open command has taken effect, but that the wait for active shards has actually failed.
This is a followup to #27551. That commit introduced a bug where the
incorrect byte buffers would be returned when we attempted a write. This
commit fixes the logic.
JDK 9 has removed JVM options that were valid in JDK 8 (e.g., GC logging
flags) and replaced them with new flags that are not available in JDK
8. This means that a single JVM options file can no longer apply to JDK
8 and JDK 9, complicating development, complicating our packaging story,
and complicating operations. This commit extends the JVM options syntax
to specify the range of versions the option applies to. If the running
JVM matches the range of versions, the flag will be used to start the
JVM otherwise the flag will be ignored.
We implement this parser in Java for simplicity, and with this we start
our first step towards a Java launcher.

This is related to #27563. In order to interface with java nio, we must
have buffers that are compatible with ByteBuffer. This commit introduces
a basic ByteBufferReference to easily allow transferring bytes off the
wire to usage in the application.
Additionally it introduces an InboundChannelBuffer. This is a buffer
that can internally expand as more space is needed. It is designed to
be integrated with a page recycler so that it can internally reuse pages.
The final piece is moving all of the index work for writing bytes to a
channel into the WriteOperation.
This commit adds a new dynamic cluster setting named `search.max_buckets` that can be used to limit the number of buckets created per shard or by the reduce phase. Each multi bucket aggregator can consume buckets during the final build of the aggregation at the shard level or during the reduce phase (final or not) in the coordinating node. When an aggregator consumes a bucket, a global count for the request is incremented and if this number is greater than the limit an exception is thrown (TooManyBuckets exception).
This change adds the ability for multi bucket aggregator to "consume" buckets in the global limit, the default is 10,000. It's an opt-in consumer so each multi-bucket aggregator must explicitly call the consumer when a bucket is added in the response.
Closes#27452#26012
Index settings didn't support reset by wildcard which also causes
issues like #27537 where archived settings can't be reset. This change
adds support for wildcards like `archived.*` to be used to reset setting to their
defaults or remove them from an index.
Closes#27537
The mappings can be submitted wrapped in a type object or not. They need to be returned in the same way as they were submitted. When applying field filters, we need to make sure that the format is preserved. MappingMetaData#getSourceAsMap removes the root level if it's the type object, which would make us overwrite the original mappings with filtered mappings but without the original root object.
Closes#27678
This commit restricts settings added to the keystore to have a lowercase
ascii name. The java Keystore javadocs state that case sensitivity of
key alias names are implementation dependent. This ensures regardless of
case sensitivity in a jvm implementation, the keys will be stored as we
expect.
Today, we prevent the system from storing a broken index template in the
transport layer, however we don't prevent this in XContent. A broken
index template can break the whole cluster state.
This commit attempts to prevent the system from constructing an index
template without a proper index patterns.
Add support for filtering fields returned as part of mappings in get index, get mappings, get field mappings and field capabilities API.
Plugins can plug in their own function, which receives the index as argument, and return a predicate which controls whether each field is included or not in the returned output.
This commit adds the node name to the names of thread pool executors so
that the node name is visible in rejected execution exception messages.
Relates #27663
The main constructor for rejected execution exception its executor
shutdown constructor parameter to the super constructor where it would
be used as a formatting parameter. This is a mistake so this commit
fixes this issue.
The RPM and Debian packages depend on coreutils (for mktemp among
others). This commit adds an explicit package dependency on coreutils.
Relates #27660
GNU mktemp and BSD mktemp have different command line flags. On some
macOS systems users have mktemp from coreutils in their PATH overriding
the system mktemp from BSD. This commit adds detection for the coreutils
mktemp versus the BSD mktemp and uses the appropriate syntax based on
the detection.

In the global checkpoint sync action, we fsync the translog. However,
the last synced global checkpoint might already be equal to the current
global checkpoint in which case the fsyncing the translog is unnecessary
as either the sync needed guard in the translog will skip the translog,
or the translog needs an fsync for another reason that will be picked up
elsewhere (e.g., at the end of a bulk request).

The hashCode contract states that equal objects must have equal hash
codes, however the unequal objects are not required to have unequal
hashCodes.
This commit rewrites GeoPointParsingTests#testEqualsHashCodeContract
using#checkEqualsAndHashCode helper.
Closes#27633
* Fix highlighting on a keyword field that defines a normalizer
The `plain` and sometimes the `unified` highlighters need to re-analyze the content to highlight a field
This change makes sure that we don't ignore the normalizer defined on the keyword field for this analysis.
After write operations in some situations we fire a post-operation
global checkpoint sync. The global checkpoint sync unconditionally
fsyncs the translog and this can then look like an fsync
per-request. This violates the translog durability settings on the index
if this durability is set to async. This commit changes the global
checkpoint sync to observe the translog durability.
