The results iterator is consuming and closing the results stream
once it is done. It seems this should not be the responsibility
of the results iterator. It stops the iterator from being reusable
for different processes where closing the stream is not desirable.
This commit is moving the consuming and closing of the results stream
into the autodetect result processor.
The conversion of timezones in JodaCompatibleZonedDateTime from joda to
java time requires the use of the DateUtils class to cater for corner
cases.
Closes#36306
The dot is used as a splitting character internally for looking up
values in the array compare condition, thus the user should use the
script condition in such cases.
This pull request adds the TransportShardCloseAction which is a
transport replication action that acquires all index shard permits for
its execution. This action will be used in the future by the
MetaDataIndexStateService in a new index closing process, where
we need to execute some sanity checks before closing an index.
The action executes the following verifications on the primary and replicas:
* there is no other on going operation active on the shard
* the data node holding the shard knows that the index is blocked for writes
* the shard's max sequence number is equal to the global checkpoint
When the verifications are done and successful, the shard is flushed.

This is related to #27260. In Elasticsearch all of the messages that we
serialize to write to the network are composed of heap bytes. When you
read or write to a nio socket in java, the heap memory you passed down
must be copied to/from direct memory. The JVM internally does some
buffering of the direct memory, however it is essentially unbounded.
This commit introduces a simple mechanism of buffering and copying the
memory in transport-nio. Each network event loop is given a 64kb
DirectByteBuffer. When we go to read we use this buffer and copy the
data after the read. Additionally, when we go to write, we copy the data
to the direct memory before calling write. 64KB is chosen as this is the
default receive buffer size we use for transport-netty4
(NETTY_RECEIVE_PREDICTOR_SIZE).
Since we only have one buffer per thread, we could afford larger.
However, if we the buffer is large and not all of the data is flushed in
a write call, we will do excess copies. This is something we can
explore in the future.
The test testLookupSeqNoByIdInLucene fails because it expects if any
change should be visible after a flush. However, that flush might be
ignored if the waitIfOngoing parameter is false (the default value), and
there is an ongoing flush triggered after merge is running.
Closes#35823
This commit moves back to use explicit dependsOn for test tasks on
check. Not all tasks extending RandomizedTestingTask should be run by
check directly.
This commit fixes an oops when pushing a change to add the building of
the Docker images. A change that was made for testing was accidentally
left behind. This commit addresses that.
This commit introduces the building of the Docker images as bonafide
packaging formats alongside our existing archive and packaging
distributions. This build is migrated from a dedicated repository, and
converted to Gradle in the process.
* Add deprecation warnings to `Rest*TermVectorsAction`, plus tests in `Rest*TermVectorsActionTests`.
* Deprecate relevant methods on the Java HLRC requests/ responses.
* Update documentation (for both the REST API and Java HLRC).
* For each REST yml test, create one version without types, and another legacy version that retains types (called *_with_types.yml).
We have a few places where we register license state listeners on
transient components (i.e., resources that can be open and closed during
the lifecycle of the server). In one case (the opt-out query cache) we
were never removing the registered listener, effectively a terrible
memory leak. In another case, we were not un-registered the listener
that we registered, since we were not referencing the same instance of
Runnable. This commit does two things:
- introduces a marker interface LicenseStateListener so that it is
easier to identify these listeners in the codebase and avoid classes
that need to register a license state listener from having to
implement Runnable which carries a different semantic meaning than
we want here
- fixes the two places where we are currently leaking license state
listeners
* Merging the zen2 branch has made it impossible to reproduce the test failure here, likely as a result of the state now being written atomically
* Closes#36189
Some IDEs (specifically Eclipse 4.8.0) needs some explicit casting for type
inference. This was added in a recent change but we should also have comments so
we remember why this needs to be there (at least for now).
Currently, we only log that WriteStateException has occurred, in
GatewayMetaState.
This PR goal is to re-throw WriteStateException to upper layers.
If dirty flag is set to false, we wrap WriteStateException in
UncheckedIOException, we prefer unchecked exception not to add
explicit throws in the multitude of layers.
If dirty flag is set to true - the world is broken. And we need to
halt the JVM. Instead of explicit halting in GatewayMetaState, we
prefer to throw IOError, which will be subsequently handled by
ElasticsearchUncaughtExceptionHandler and JVM will be halted.
This PR also adds tests for WriteStateException.
The Eclipse IDE java compiler seems to need some special hints about what types
some functions used in the tests return. Correcting this for some test that were
newly merged to master.
- GetSslCertificatesRequest need not implement toXContentObject

Today the InternalTestClusterTests sometimes set up a cluster with a single
master, start some other ndoes, shut the original master down, and then reset
the cluster. This doesn't really work, because the original master may be
stale. This change avoids shutting down the only master in this situation.
This change removes the custom serialization of the total hits
and reuses the shard's serialization of Lucene#read/writeTopDocs
in the client code. This also removes the incorrect assertion that
trips randomly in bwc tests.
Closes#36284
Set rest_total_hits_as_int in search requests only on the new cluster,
the old cluster can be on a version older than don't support this
parameter (< 6.6) and total hits is not an object in 6x anyway.
Closes#36291
Currently we use Math.random() in a few places in the tests which makes these
tests not reproducable with the random seed mechanism that comes with
ESTestCase. The change removes those instances.
This commit hides ClusterStates that have a STATE_NOT_RECOVERED_BLOCK from
ClusterStateAppliers. This is needed, because some appliers, such as IngestService, rely on
the fact, that cluster states with STATE_NOT_RECOVERED_BLOCK won't contain anything useful.
Once the state is recovered it's fully available for the appliers. This commit also switches many of
the remaining tests that require state persistence/recovery from Zen1 to Zen2.
