Relates to #31324. It seems like Gradle has an inconsistent behavior and
the taks is not always replaced.
* Include number of non conforming tasks in the exception.
* No longer replace test task, create implicit instead
Closes#31324. The issue has full context in comments.
With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.
* Revert "No longer replace test task, create implicit instead"
This reverts commit f1ebaf7d93e4a0a19e751109bf620477dc35023c.

With PR #31574 we now ensure that connections are established under the proper
thread context. There is a test in RemoteClusterConnectionTests, however,
that shuts down the service while connecting. With the above change, a new kind
of exception can occur that the test is unaware of.
Added support to the high-level rest client for the create snapshot API call. This required
several changes to toXContent which may need to be cleaned up in a later PR. Also
added several parsers for fromXContent to be able to retrieve appropriate responses
along with tests.
Establishing remote cluster connections uses a queue to coordinate multiple concurrent connect
attempts. Connect attempts can be initiated by user triggered searches as well as by system events
(e.g. when nodes disconnect). Multiple such concurrent events can lead to the connectListener of
one event to be called under the thread context of another connect attempt. This can lead to the
situation as seen in #31462 where the connect listener is executed under the system context, which
breaks when fetching the search shards from the remote cluster.
Closes#31462
Currently RandomObjects::addFields can potentially generate a large number of fields This commit decreases the chances that a new object or array is added as a new branch of an object, which lowers the probability of ending up with very big documents generated. It also reduces the number of documents generated for the SimulatePipelineResponseTests from 10 to 5 to reduce the testing time required for parsing.
This commit enhances the assertion message when de-duplicating values on
a thread context header so that if this assertion trips we can see the
values and their correpsonding unique values to understand why this
assertion might trip.
AliasOrIndex.Alias#writeIndex was returning a write index when
an alias was pointing to only one index, regardless whether `is_write_index` was
set to `false`. This fixes that so that there is no write index in such a case
that an alias points to only one index with `is_write_index=false`.

* Rename "agg" Scripted Metric Aggregation script context variable to "state"
* Rename a private base class from ...Agg to ...State that I missed in my last commit
* Clean up imports after merge
TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
Introduces support for multiple host providers, which allows the settings based hosts resolver to be
treated just as any other UnicastHostsProvider. Also introduces the notion of a HostsResolver so
that plugins such as FileBasedDiscovery do not need to create their own thread pool for resolving
hosts, making it easier to add new similar kind of plugins.
Get Mapping currently throws index not found exception (and returns
404 status code) from the REST layer whenever an index was specified
and no indices have been returned. We should not have this logic in the
REST layer though as only our index resolver should decide whether we
need to throw exceptions or not based on provided indices and corresponding
indices options.
Closes#31485
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
We renamed `createNewTranslog` to `fileBasedRecovery` in the
RecoveryTarget but did not do this for RecoverySourceHandler.
This commit makes sure that we a consistent parameter in both
recovery source and target.
With #20695 we removed local transport and there is just TransportAddress now. The
UnicastHostsProvider currently returns DiscoveryNode instances, where, during pinging, we're
actually only making use of the TransportAddress to establish a first connection to the possible new
node. To simplify the interface, we can just return a list of transport addresses instead, which
means that it's not necessary anymore to create fake node objects in each plugin just to return the
address information.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
The QueryCachingPolicy#ALWAYS_CACHE was deprecated in Lucene-7.4 and
will be removed in Lucene-8.0. This change replaces it with QueryCachingPolicy.
This also makes INDEX_QUERY_CACHE_EVERYTHING_SETTING visible in testing only.
The `multiplexer` filter emits multiple tokens at the same position, each
version of the token haivng been passed through a different filter chain.
Identical tokens at the same position are removed.
This allows users to, for example, index lowercase and original-case tokens,
or stemmed and unstemmed versions, in the same field, so that they can search
for a stemmed term within x positions of an unstemmed term.
Currently, DateHistogramAggregationBuilder#rewriteTimeZone uses the aggregation
date math parser and time zone to check whether all values in a read have the
same timezone to speed up computation. However, the upper and lower bounds to
check are retrieved as longs in epoch_millis, so they don't need to get parsed
using a time zone or a parser other than "epoch_millis". This changes this
behaviour that was causing problems when the field type mapping was specifying
only "epoch_millis" as a format but a different timezone than UTC was used.
Closes#31392
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
#31241 changed the cluster state update tasks to run under system context. The context wrapping
did not preserve response headers, though. This has led to a test failure on 6.x #31408, as the
deprecation warnings were not carried back anymore to the caller when creating an index. This
commit changes the restorable context supplier to preserve response headers.
Since #30966, Action no longer has anything but a call to the
GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
Today if a write replication request fails, we will send a shard-failed
message to the master node to fail that replica. However, if there are
many ongoing write replication requests and the master node is busy, we
might overwhelm the cluster and the master node with many shard-failed
requests.
This commit tries to minimize the shard-failed requests in the above
scenario by caching the ongoing shard-failed requests.
This issue was discussed at
https://discuss.elastic.co/t/half-dead-node-lead-to-cluster-hang/113658/25.
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.
Relates #30603
The other metric aggregations (min/max/etc) return `null` as their XContent value and string when nothing was computed (due to empty/missing fields). Percentiles and Percentile Ranks, however, return `NaN `which is inconsistent and confusing for the user. This fixes the inconsistency by making the aggs return `null`. This applies to both the numeric value and the "as string" value.
Note: like the metric aggs, this does not change the value if fetched directly from the percentiles object, which will return as `NaN`/`"NaN"`. This only changes the XContent output.
While this is a bugfix, it still breaks bwc in a minor way as the response changes from prior version.
Closes#29066
