Previously persistent task assignment was checked in the
following situations:
- Persistent tasks are changed
- A node joins or leaves the cluster
- The routing table is changed
- Custom metadata in the cluster state is changed
- A new master node is elected
However, there could be situations when a persistent
task that could not be assigned to a node could become
assignable due to some other change, such as memory
usage on the nodes.
This change adds a timed recheck of persistent task
assignment to account for such situations. The timer
is suspended while checks triggered by cluster state
changes are in-flight to avoid adding burden to an
already busy cluster.
Closes#35792
* We should compare the target value with the to be applied value before interpreting the update as a change
* This speeds up the test failing in #36496 considerably by preventing state updates on noop setting updates
This commit add support to engine operations for resolving and verifying the sequence number and
primary term of the last modification to a document before performing an operation. This is
infrastructure to move our (optimistic concurrency control)[http://en.wikipedia.org/wiki/Optimistic_concurrency_control] API to use sequence numbers instead of internal versioning.

There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.
Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.
This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
data files under the cluster name subdirectory has been deprecated and was
meant to be removed in 6.0. This commit removes some leftover referrences to
these paths.
The error message used when attempting to delete a lifecycle policy that
is in use previously only included one index which was using the policy.
It now includes all indices using that policy.
Includes the following:
* Reversion of doc-values changes in LUCENE-8374; we are interested in seeing if this
has an effect on benchmarks for node-stats and index-stats
* More improvements to docvalues updates
The security documentation test uses
SecureRandom#getStrongInstance. This defaults to
securerandom.strongAlgorithms=NativePRNGBlocking:SUN,DRBG:SUN which
means a blocking implementation that reads from /dev/random. This means
that this test can stall if the entropy on the machine is
exhausted. Anyway, it also means that the randomness is
non-reproducible, a thing that we try to avoid in tests. This commit
switches to a boring randomness source to avoid the blocking, and to
keep the test reproducible.
* Make sure to test conversion for both typed and typeless HLRC requests.
* Update a few more statements to deprecatedAndMaybeLog.
* Make sure Rest*SearchTemplateActionTests extend RestActionTestCase.
Currently TransportRequestOptions allows specific requests to request
compression. This commit removes this and always compresses based on the
settings. Additionally, it removes TransportResponseOptions as they
are unused.
This closes#36399.
* Fix CorruptFileIT to also take last DV generation into account
We currently only prune old .liv generations. With soft_deletes it's important
to also prune DV generations.
* Fix CorruptionUtils to skip the footer bytes after the checksum is read.
Today we read a broken checksum since we also checksum the 8 footer bytes that include
the checksum algorithm and the footer magic.
Closes#36526
Currently, the `BytesStreamOutput` always zeros out the underlying byte
pages when they are acquired. This should not be necessary as the stream
overwrites the underlying bytes as serialization occurs.
`PageCacheRecycler` is the class that creates and holds pages of arrays
for various uses. `BigArrays` is just one user of these pages. This
commit moves the constants that define the page sizes for the recycler
to be on the recycler class.
This commit moves the node field in the JoinRequest object to be a
private field, adding a dedicated accessor. This is a minor breaking
change in that it is no longer possible for all callers to overwrite
this field, but that is a feature.
Changed AutofollowCoordinator makes use of the wait_for_metadata_version
feature in cluster state API and removed hard coded poll interval.

An issue was introduced due to the merge of authorization_realms with
the change to use Affix Settings for realms.
The ".type" setting no longer exists as the type is now part of the
setting key.
* Don't print download progress in batch mode
With this change we will no longer provide the progress bar in batch
mode.
Assuming that this is mode is mainly for consumption by tools which
will serialize the output, we shouldn't print a progress bar to be
for every percentile.
* PR review
- fix up to date checks to ignore elasticsearch jars. We were not scanning them but these still triggered a rebuild.
- add tests to assert correct behavior and up to date checks.
- make the task less verbose with `-i` and include the output only on errors.
* Upgrae plugin to latest and expose udp
* Explicit check for windows
* Rename the properties for the port numbers
* Tasks for pre and pos container actions
The auto follow coordinator keeps track of the UUIDs of indices that it has followed. The index UUID strings need to be cleaned up in the case that these indices are removed in the remote cluster.

This commit moves the MergedDateFormatter to a package private class and
reworks joda DateFormatter instances to use that instead of a single
DateTimeFormatter with multiple parsers. This will allow the java and
joda multi formats to share the same format parsing method in a
followup.
This adds the _security/user/_privileges API to the High
Level Rest Client.
This also makes some changes to the Java model for the Role APIs
in order to better accommodate the GetPrivileges API
Redeprecates the `/_xpack/rollup` endpoints in favor of `/_rollup`.
When we cleanup the rollup in a cluster containing 6.x nodes we need to
use `/_xpack/rollup` instead of `/_rollup` because the 6.x nodes don't
know about `/_rollup`. In those cases we must ignore the deprecation
warnings that the 7.0 node will return for the end point.
Closes#36044
* Renamed DAY_OF_WEEK and WEEK_OF_YEAR functions to their ISO version and
added the same functions with different functionality.
* Rewritten the datetime functions documentation to follow the format of the other
functions documentation pages.
Currently our handshake requests do not include a version. This is
unfortunate as we cannot rely on the stream version since it is not the
sending node's version. Instead it is the minimum compatibility version.
The handshake request is currently empty and we do nothing with it. This
should allow us to add data to the request without breaking backwards
compatibility.
This commit adds the version to the handshake request. Additionally, it
allows "future data" to be added to the request. This allows nodes to craft
a version compatible response. And will properly handle additional data in
future handshake requests. The proper handling of "future data" is useful
as this is the only request where we do not know the other node's version.
Finally, it renames the TcpTransportHandshaker to
TransportHandshaker.
This adds casts for the def type to all standard boxed types. Prior to this certain
casts such as def [long/Long] -> Double would fail which does not follow the
goals of the Painless casting model to remove the need for explicit boxing. This
also creates symmetry with the casts for the newly created bridge methods
being called at run-time.
Our Docker build uses a multi-stage Docker build. This requires Docker
version 17.05 or greater. Without an explicit check here, the build
fails in a mysterious way such as "invalid reference format" that is
hard to track down (Google searches for "Docker invalid reference
format" do not turn up anything useful). This commit refactors our
existing Docker checks, and adds a new one for the minimum Docker
version.
This commit contains a few minor changes to our search code:
- adjust the visibility of a couple of methods in our search code to package private from public or protected.
- make some of the `SearchPhaseController` methods static where possible
- rename one of the `SearchPhaseController#reducedQueryPhase` methods (used only for scroll requests) to `reducedScrollQueryPhase` without the `isScrollRequest` argument which was always set to `true`
- replace leniency in `SearchPhaseController#setShardIndex` with an assert to make sure that we never set the shard index twice
- remove two null checks where the checked field can never be null
- resolve an unchecked warning
- replace `List#toArray` invocation that creates an array providing the true size with array creation of length 0
- correct a couple of typos in comments
The different `DocValueFormat` implementors throw `UnsupportedOperationException` for methods that they don't support. That is perfectly fine, and quite common as not all implementors support all of the possible formats. This makes it hard though to trace back which implementors support which formats as they all implement the same methods.
This commit introduces default methods in the `DocValueFormat` interface so that all methods throw `UnsupportedOperationException` by default. This way implementors can override only the methods that they specifically support.
This commit modifies BigArrays to take a circuit breaker name and
the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.
Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.
Finally, this commit closes#31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.
Adding logging to confirm the suspicion that there might be another old index
lingering around in the test cluster in cases where this test occasionally
fails.
