This commit adds an InboundHandler to handle inbound message processing.
With this commit, this code is moved out of the TcpTransport.
Additionally, finer grained unit tests are added to ensure that the
inbound processing works as expected
Replicated closed indices can't be indexed into or searched, and therefore don't need a shard with
full indexing and search capabilities allocated. We can save on a lot of heap memory for those
indices by not allocating a mapper service and caching infrastructure (which preallocates a constant
amount per instance). Before this change, a 1GB ES instance could host 250 replicated closed
metricbeat indices (each index with one shard). After this change, the same instance can host 7300
replicated closed metricbeat instances (not that this would be a recommended configuration). Most
of the remaining memory is in the cluster state and the IndexSettings object.
Switches "discovery.type: single-node" from using a separate implementation for single-node discovery to using the existing standard discovery implementation, with two small adaptions:
- auto-bootstrapping, but requiring initial_master_nodes not to be set.
- not actively pinging other nodes using the Peerfinder
- not allowing other nodes to join its single-node cluster (if they have e.g. been set up using regular discovery and connect to the single-disco node).
Currently there are some components of message serializer and sending
that still occur in TcpTransport. This commit makes it possible to
send a message without the TcpTransport by moving all of the remaining
application logic to the OutboundHandler. Additionally, it adds unit
tests to ensure that this logic works as expected.
Previously, `getTime(colIdx/colLabel)` and
`getObject(colIdx/colLabel, java.sql.Time.class)` methods were computing
the time from a `ZonedDateTime` by applying day in millis modulo on the epoch millis
of the `ZonedDateTime` object. This is wrong as we need to keep the time
related fields at the timezone of the `ZonedDateTime` object and just
set the date info to the epoch date (01/01/1970).
Additionally fixes a testing issue as the original timezone id is converted
to an offset string when parsing the response from the server.
This test inadvertently asserts that the election occurs after a master failure
is clean. However, messy elections are a fact of life so we should not fail on
a messy election.
This change moves this test away from an `AbstractDisruptionTestCase` since it
does not need the fault detector to be so enthusiastic, and weakens the
assertions to merely say that we ignore states published by the old master
without saying anything about the cleanliness of the election.
Closes#36556
Today the upgrade assistant identifies that discovery configuration is required
in production mode, but links to docs saying to add one of these settings:
- `discovery.seed_hosts`
- `discovery.seed_providers`
- `cluster.initial_master_nodes`
However these settings do not exist in 6.7 so this is unhelpful advice. This
commit adjusts the docs to give more useful advice to users arriving at this
page from the upgrade assistant.

Currently the TransportMessageListener is applied and used in the
Transport class. However, local requests and responses never make it to
this class. This PR moves the listener add/remove methods to the
TransportService. After this change the Transport can only have one
listener set with it. This one listener is the TransportService, which
will then propogate the events to the external listeners.

The current documentation recommends disabling allocations of all shards. This prevents shards of
new indices from being allocated as well. That means that during a rolling upgrade, operations like
roll over and index shrinking will operate correctly. This, in turn, can cause issues for data ingestion
and ILM.
Java-time fails parsing composite patterns when first pattern matches only the prefix of the input. It expects pattern in longest to shortest order. Because of this constructing just one DateTimeFormatter with appendOptional is not sufficient. Parsers have to be iterated and if the parsing fails, the next one in order should be used. In order to not degrade performance parsing should not be throw exceptions on failure. Format.parseObject was used as it only returns null when parsing failed and allows to check if full input was read.

The implementation of TransportIndexAction and TransportDeleteAction as
TransportReplicationAction existed for interoperability with older 5.x nodes, as these older nodes
coordinated single index / deletes as replication requests. This BWC layer is no longer needed in 7.x,
where these single actions are now mapped to bulk requests. Completely removing the deprecated
transport actions is not possible yet if we want to keep BWC with a 6.x transport client. The best
way here is to wait for the transport client to go away and then just remove the actions.
While yum does retry retrieving files 10 times by default [1], slow
network fetches, governed by `minrate` cause immediate aborts without
getting retried.
Wrap yum commands in a 10 iteration retry loop.

On windows, JAVA_HOME is currently resolved when the windows service is started. However, this is contrary to what our documentation states. This commit moves resolution to service install. This has the side effect of making java existence checking optional in elasticsearch-env.bat, since the rest of the service commands do not require java.

The platformTest gradle task was a packaging test meant to ensure unit
tests run on the various supported operating systems without relying on
CI to maintain a full matrix of platforms. Howevever, it never really
worked out as intended and is now additional code in our vagrant setup
to maintain. This commit removes the platformTest task.
Each cluster state publication schedules a cancellation task with the provided publication timeout
(30s by default). This scheduled cancellation keeps a reference to the publication, and therefore the
full cluster state that was published. In case of frequently updating a large cluster state, this results
in a large number of cancellation tasks keeping references to all previously published cluster states.
This change removes the use of hardcoded port values for the
idp-fixture in favor of the mapped ephemeral ports. This should prevent
failures due to port conflicts in CI.
FilterDirectory.getPendingDeletions does not delegate, fixed
temporarily by overriding in StoreDirectory.
This in turn caused duplicate file name use after a trimUnsafeCommits
had been done, since a new IndexWriter would not consider the pending
deletes in IndexFileDeleter. This should only happen on windows (AFAIK).
Reenabled doing index updates for all tests using
IndexShardTests.indexOnReplicaWithGaps (which could fail due to above
when using mocked WindowsFS).
Added getPendingDeletions delegation to all elasticsearch
FilterDirectory subclasses that were not trivial test-only overrides to
minimize the risk of hitting this issue in another case.
* Revert "Configure TMP for test nodes on Windows (#39959)"

Here are the highlights of this release:
- Feature variants AKA "optional dependencies"
- Type-safe accessors in Kotlin precompiled script plugins
- Gradle Module Metadata 1.0
For more details see https://docs.gradle.org/5.3/release-notes.html
The script will be use in CI to configure our own Artifactory instance
so CI does not depend on external network resources nor do we generate
excessive load on these resources.
In case the repo is not accessible Gradle should fall back to using the
public ones.
