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.
Added helper methods to ESRestTestCase for checking warnings in mixed and current-version-only clusters.
This is supported by a new VersionSpecificWarningsHandler class with associated unit test.
Closes#36251
Today the Zen2 coordinator only applies a write block when there is no known
elected master, ignoring the `discovery.zen.no_master_block` setting. This
commit resolves this, applying the correct block according to the configuration
instead.
Today we do not enforce soft-deletes when accessing the Lucene changes
snapshot. This might lead to internal errors because we assume
soft-deletes are enabled in that code path.
1. CCR tests work without any changes
2. `testDanglingIndices` require changes the source code (added TODO).
3. `testIndexDeletionWhenNodeRejoins` because it's using just two
nodes, adding the node to exclusions is needed on restart.
4. `testCorruptTranslogTruncationOfReplica` starts dedicated master
one, because otherwise, the cluster does not form, if nodes are stopped
and one node is started back.
5. `testResolvePath` needs TEST cluster, because all nodes are stopped
at the end of the test and it's not possible to perform checks needed
by SUITE cluster.
6. `SnapshotDisruptionIT`. Without changes, the test fails because Zen2
retries snapshot creation as soon as network partition heals. This
results into the race between creating snapshot and test cleanup logic
(deleting index). Zen1 on the
other hand, also schedules retry, but it takes some time after network
partition heals, so cleanup logic executes latter and test passes. The
check that snapshot is eventually created is added to
the end of the test.
This adds tests for each possible cast of def to a primitive type both implicit
and explicit. This also fixes a minor bug where we were only checking the type
of a def to be Number in some explicit casts. This does not work because it
allows possible unintended casts from BigInteger and BigDecimal to primitive
types since they both extend Number but are not included as part of the
Painless casting model.
Adds a setting that indicates that an index is done indexing, set by ILM
when the Rollover action completes. This indicates that the Rollover
action should be skipped in any future invocations, as long as the index
is no longer the write index for its alias.
This enables 1) an index with a policy that involves the Rollover action
to have the policy removed and switched to another one without use of
the move-to-step API, and 2) integrations with Beats and CCR.
This commit adds Zulu to the CI rotation. This commit only means that we
are going to try running CI against Zulu, it does not carry any
implications of support in the past, now, or in the future.
Today we log a slightly cryptic "cluster bootstrapping is disabled on this
node" message if bootstrapping hasn't been configured. Since there is today
only one way to bootstrap the cluster it seems preferable to spell out exactly
which setting is missing.
* Lower fielddata circuit breaker default limit
Lower fielddata circuit breaker default limit from 60% to 40% as we have
moved to doc_values for most of the cases.
* merge master in
* update tests
* update docs
Deals with a situation where a follower becomes disconnected from the leader, but only for such a
short time where it becomes candidate and puts up a NO_MASTER_BLOCK, but then receives a
follower check from the leader. If the leader does not notice the node disconnecting, it is important
for the node not to be turned back into a follower but try and join the leader again.
We still should prefer the node into a follower on a follower check when this follower check triggers
a term bump as this can help during a leader election to quickly have a leader turn all other nodes
into followers, even before the leader has had the chance to transfer a possibly very large cluster
state.
Closes#36428
* This commit is part of our plan to deprecate and ultimately remove the use of _xpack in the REST APIs.
- REST API docs
- HLRC docs and doc tests
- Handle REST actions with deprecation warnings
- Changed endpoints in rest-api-spec and relevant file names
Bulk requests comprise many individual actions, and the responses for each
action comes back in the same order (see e.g. `DocumentActionsIT#testBulk()`).
However the docs do not seem to explicitly state this vital fact. This commit
addresses that omission.
The following updates were made:
- Add a new untyped endpoint `{index}/_explain/{id}`.
- Add deprecation warnings to Rest*Action, plus tests in Rest*ActionTests.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit converts the watcher execution context to use the joda
compat java time objects. It also again removes the joda methods from
the painless whitelist.
For each API, the following updates were made:
- Add deprecation warnings to `Rest*Action`, plus tests in `Rest*ActionTests`.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit changes the Docker assemble tasks so that they attempt to
build Docker if the Docker binaries exist, of if build.docker is set to
true. If the Docker binaries do not exist, or if build.docker is set to
false, then no attempt is made to build the Docker images.
The transport client was linking to a page in maven central that didn't
have the transport client in it. This is better link and happens to be
the same link that the low and high level rest client use.
Allow `auto_date_histogram` as a valid parent agg for derivative,
cumulative sum, moving average, moving function and serial
differencing pipeline aggregations.
Since all these aggs share the same requirement (sequentially
ordered parent aggs), this commit also refactors to share
the same validation code so that any newly added aggs won't
be forgotten.
Closes#35578
* Add non-X-Pack centric rollup endpoints
This commit adds new endpoints for rollup that do not have _xpack in
their path. The purpose for this change is to take these endpoints into
6.x as well so that they can be available in mixed cluster tests too. A
follow-up change will deprecate the use of _xpack in the rollup
endpoints. And finally, in the future, we would remove the _xpack
endpoints.
* Remove import
* Fix typo
This change adds a way to provide the content type of the rest serialization
tests when creating random instances. This is used by SearchHitsTests to ensure
that the internal members of the class are created with the same xContentType
and that equals can be used to compare an instances created from an XContent
view.
Today the `GetDiscoveredNodesAction` waits, possibly indefinitely, to discover
enough nodes to bootstrap the cluster. However it is possible that the cluster
forms before a node has discovered the expected collection of nodes, in which
case the action will wait indefinitely despite the fact that it is no longer
required.
This commit changes the behaviour so that the action fails once a node receives
a cluster state with a nonempty configuration, indicating that the cluster has
been successfully bootstrapped and therefore the `GetDiscoveredNodesAction`
need wait no longer.
Relates #36380 and #36381; reverts 558f4ec278.
Previously, we used a CamelCase to CAMEL_CASE transformation to get the
primary name of a function from its class name which led to some issues
since there are functions that we don't want to be registered this way
(e.g.: IFNULL). To simplify the logic and avoid and "magic"
transformations in the FunctionRegistry a primary name must be provided
explicitely for each function.
The same change is applied for the function resolution (when a function
is used in an SQL statement). There is no CamelCase to CAMEL_CASE
transformation but only upper-casing is applied (fuNcTiOn -> FUNCTION).
This commit adds support for the index templates exist API, creating
new client-side request types for that API and the get index
templates API. Also adds links in hlrc docs to pages for supported
index template APIs
This commit creates JodaDateFormatter to replace
FormatDateTimeFormatter. It converts all uses of the old class
to DateFormatter to allow a future change to use JavaDateFormatter
when appropriate.
