Improve RemoteConnectionManager consistency (#55759)
In order to iterate through remote connections, the remote connection
manager maintains a local cache of connected nodes. Unfortunately this
is difficult in relationship with testing as it is inherently racy in
comparison to the parent connection manager map of connections.

This commit improves the relationship by only returning a cached
connection if it is still registered with the parent. If the connection
is not open, we will go to the slow path of allocating a iterator
directly from the parent.

David Turner 445cf32591 Stop exposing ExecutorService from DeterministicTaskQueue (#56001)
There are no real users of `DeterministicTaskQueue#getExecutorService()` so we
can remove those public methods and expose the `ExecutorService` only through
the corresponding `ThreadPool`.

Make SAME Pool on DeterministicTaskQueue more Realistic (#55931) (#55999)
By forking off the `SAME` pool tasks and executing them in random order,
we are actually creating unrealisticc scenarios and missing the actual order
of operations (whatever task that puts the task on the `SAME` queue will always
run before the `SAME` queued task will be executed currently).
Also, added caching for the executors. It doesn't matter much, but saves some objects
and makes debugging a little easier because executor object ids make more sense.

[7.x] Modified searchAndReduce() to return empty agg when no docs exist (#55967)
Backports #55826 to 7.x

    Modified AggregatorTestCase.searchAndReduce() method so that it returns an empty aggregation result when no documents have been inserted.

    Also refactored several aggregation tests so they do not re-implement method AggregatorTestCase.testCase()

    Fixes #55824

Retry failed peer recovery due to transient errors (#55883)
Currently a failed peer recovery action will fail an recovery. This
includes when the recovery fails due to potentially short lived
transient issues such as rejected exceptions or circuit breaking
errors.

This commit adds the concept of a retryable action. A retryable action
will be retryed in face of certain errors. The action will be retried
after an exponentially increasing backoff period. After defined time,
the action will timeout.

This commit only implements retries for responses that indicate the
target node has NOT executed the action.

Introduce mechanism to stub request handling (#55832)
Currently there is a clear mechanism to stub sending a request through
the transport. However, this is limited to testing exceptions on the
sender side. This commit reworks our transport related testing
infrastructure to allow stubbing request handling on the receiving side.

Zachary Tong 715c90bf7d Aggs must specify a `field` or `script` (or both) (#52226)
This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user.  This is technically
required today already, but throws an exception much deeper
in the agg framework and has a very unintuitive error for the user
(as well as eating more resources instead of failing early)

Add geo_shape mapper supporting doc-values in Spatial Plugin (#55037) (#55500)
After #53562, the `geo_shape` field mapper is registered within
a module. This opens the door for introducing a new `geo_shape`
field mapper into the Spatial Plugin that has doc-values support.

This is very much an extension of server's GeoShapeFieldMapper,
but with the addition of the doc values implementation.

Remove Redundant CS Update on Snapshot Finalization (#55276) (#55528)
This change folds the removal of the in-progress snapshot entry
into setting the safe repository generation. Outside of removing
an unnecessary cluster state update, this also has the advantage
of removing a somewhat inconsistent cluster state where the safe
repository generation points at `RepositoryData` that contains a
finished snapshot while it is still in-progress in the cluster
state, making it easier to reason about the state machine of
upcoming concurrent snapshot operations.

Identify backing indices for data streams 2020-04-21 07:43:10 -05:00
Yannick Welsch ba39c261e8 Use streaming reads for GCS (#55506)
To read from GCS repositories we're currently using Google SDK's official BlobReadChannel,
which issues a new request every 2MB (default chunk size for BlobReadChannel) using range
requests, and fully downloads the chunk before exposing it to the returned InputStream. This
means that the SDK issues an awfully high number of requests to download large blobs.
Increasing the chunk size is not an option, as that will mean that an awfully high amount of
heap memory will be consumed by the download process.

The Google SDK does not provide the right abstractions for a streaming download. This PR
uses the lower-level primitives of the SDK to implement a streaming download, similar to what
S3's SDK does.

Also closes #55505

Make RepositoryData Less Memory Heavy (#55293) (#55468)
We don't really need `LinkedHashSet` here. We can assume that all the
entries are unique and just use a list and use the list utilities to
create the cheapest possible version of the list.
Also, this fixes a bug in `addSnapshot` which would mutate the existing
linked hash set on the current instance (fortunately this never caused a real world bug)
and brings the collection in line with the java docs on its getter that claim immutability.

David Turner 0458770556 Rebooted master-ineligibles should not bootstrap (#55302)
In #55298 we saw a failure of `CoordinationStateTests#testSafety` in which a
single master-eligible node is bootstrapped, then rebooted as a
master-ineligible node (losing its persistent state) and then rebooted as a
master-eligible node and bootstrapped again.

This happens because this test loses too much of the persistent state; in fact
once bootstrapped the node would not allow itself to be bootstrapped again.
This commit adjusts the test logic to reflect this.

Closes #55298

Zachary Tong f46b567563 Convert InternalAggTestCase to AbstractNamedWriteableTestCase (#55250)
Some aggregations, such as the Terms* family, will use an alternate
class to represent unmapped shard results (while the rest of the aggs
use the same object but with some form of "empty" or "nullish" values
to represent unmapped).

This was problematic with AbstractWireSerializingTestCase because it
expects the instanceReader to always match the original class.  Instead,
we need to use the NamedWriteable version so that the registry
can be consulted for the proper deserialization reader.

Make data streams in APIs resolvable. (#55337)
Backport from: #54726

The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.

In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.

Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

* Remove VST Any (#51539)

* Rewire terms agg to use new VS registry (#51182)

Also adds some basic AggTestCases for untested code
paths (and boilerplate for future tests once the IT are

* Wire Cardinality aggregation to work with the ValuesSourceRegistry (#51337)

* Wire Percentiles aggregator into new VS framework (#51639)

This required a bit of a refactor to percentiles itself.  Before,
the Builder would switch on the chosen algo to generate an
algo-specific factory.  This doesn't work (or at least, would be
difficult) in the new VS framework.

This refactor consolidates both factories together and introduces
a PercentilesConfig object to act as a standardized way to pass
algo-specific parameters through the factory.  This object
is then used when deciding which kind of aggregator to create

Note: CoreValuesSourceType.HISTOGRAM still lives in core, and will
be moved in a subsequent PR.

* Unmute testSupportedFieldTypes, fix Percentiles/Ranks/Terms tests (#52734)

numeric, but in fact also accepts Boolean and Date (because those are
numeric on master - thanks `testSupportedFieldTypes` for catching it!)

* ValuesSource Refactor: move histo VSType into XPack module (#53298)

- Introduces a new API (`getBareAggregatorRegistrar()`) which allows plugins to register aggregations against existing agg definitions defined in Core.
- This moves the histogram VSType over to XPack where it belongs. `getHistogramValues()` still remains as a Core concept
- Moves the histo-specific bits over to xpack (e.g. the actual aggregator logic). This requires extra boilerplate since we need to create a new "Analytics" Percentile/Rank aggregators to deal with the histo field. Doubly-so since percentiles/ranks are extra boiler-plate'y... should be much lighter for other aggs

Voting config exclusions should work with absent nodes (#55291)
Today the voting config exclusions API accepts node filters and resolves them
to a collection of node IDs against the current cluster membership.

This is problematic since we may want to exclude nodes that are not currently
members of the cluster. For instance:

- if attempting to remove a flaky node from the cluster you cannot reliably
  exclude it from the voting configuration since it may not reliably be a
  member of the cluster

- if `cluster.auto_shrink_voting_configuration: false` then naively shrinking
  the cluster will remove some nodes but will leaving their node IDs in the
  voting configuration. The only way to clean up the voting configuration is to
  grow the cluster back to its original size (potentially replacing some of the
  voting configuration) and then use the exclusions API.

This commit adds an alternative API that accepts node names and node IDs but
not node filters in general, and deprecates the current node-filters-based API.

Relates #47990.
Backport of #50836 to 7.x.

Remove deprecated third-party methods from tests (#55255) (#55269)

warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.

NodeInfo response should use a collection rather than fields (#54460) (#55132)
This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.

In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."

I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.

Make some agg tests easier to read (#54954) (#55079)
We added a fancy method to provide random realistic test data to the
reduction tests in #54910. This uses that to remove some of the more
esoteric machinations in the agg tests. This will marginally increase
the coverage of the serialiation tests and, more importantly, remove
some mysterious value generation code that only really made sense for
random reduction tests but was used all over the place. It doesn't, on
the other hand, make the tests shorter. Just *hopefully* more clear.

I only cleaned up a few tests this way. If we like this it'd probably be
worth grabbing others.

Rename field name constants in AbstractBuilderTestCase (#53234)
Some field name constants were not updaten when we moved from "string" to "text"
and "keyword" fields. Renaming them makes it easier and faster to know which
field type is used in test subclassing this base test case.

Nik Everett 54ea4f4f50 Begin to drop pipeline aggs from the result tree (backport of #54311) (#54659)
Removes pipeline aggregations from the aggregation result tree as they
are no longer used. This stops us from building the pipeline aggregators
at all on data nodes except for backwards compatibility serialization.
This will save a tiny bit of space in the aggregation tree which is
lovely, but the biggest benefit is that it is a step towards simplifying
pipeline aggregators.

This only does about half of the work to remove the pipeline aggs from
the tree. Removing all of it would, well, double the size of the change
and make it harder to review.

Fix pipeline agg serialization for ccs (backport of #54282) (#54468)
This fixes pipeline aggregations used in cross cluster search from an older
version of Elasticsearch to a newer version of Elasticsearch. I broke
this in #53730 when I was too aggressive in shutting off serialization
of pipeline aggs. In particular, this comes up when the coordinating
node is pre-7.8.0 and the gateway node is on or after 7.8.0.

The fix is another step down the line to remove pipeline aggregators
from the aggregation tree. Sort of. It create a new
`List<PipelineAggregator>` member in `InternalAggregation` *but* it is
only used for bwc serialization and it is fed by the mechanism
established in #53730 to read the pipelines from the
