When JAVA_HOME is not set we try to detect the location of Java. If its
location contains a space, due to a lack of quoting we will be
unsuccessful in invoking Java. This commit adds the necessary quoting to
handle this case.

Tests were randomly assigning `targetField` to an existing field that was an array,
causing path resolution issues. This PR fixes those tests
Closes#25346 & #25348
`InternalEngineTests.testConcurrentWritesAndCommits` can be very heavy on disks
if threads are slow and the main thread keeps on pulling commit points holding on
to many many segments. This commit adds some quadratic backoff to not pile up too many
commits and to make sure indexing threads can make progress. This also now doesn't do
busy waiting but waits on a latch with a timeout.
Closes#25110
Custom whitelists in Painless will need to allow classes to be augmented beyond the currently hard-coded Augmentation class tied to Painless directly. This change allows any class to specify an augmentation on a Painless struct using an appropriate static method. Changes to loading the whitelist have also been created to allow for this specification of a different class for augmentation.
In #24379 we added ability to upgrade templates on full cluster startup. This PR invokes the same update procedure also when a new node first joins the cluster allowing to update templates on a rolling cluster restart as well.

When shrinking an index we initialize its max unsafe auto ID timestamp
to the maximum of the max unsafe auto ID timestamps on the source
shards.

#25147 added the translog deletion policy but didn't enable it by default. This PR enables a default retention of 512MB (same maximum size of the current translog) and an age of 12 hours (i.e., after 12 hours all translog files will be deleted). This increases to chance to have an ops based recovery, even if the primary flushed or the replica was offline for a few hours.
In order to see which parts of the translog are committed into lucene the translog stats are extended to include information about uncommitted operations.
Views now include all translog ops and guarantee, as before, that those will not go away. Snapshotting a view allows to filter out generations that are not relevant based on a specific sequence number.

This change cleans up core tests to not use `index.mapping.single_type=false`
but instead where applicable use a single type or markt the index as created
with a pre 6.x version.

Due to limitations with CreateProcessW on Windows (ultimately used by
ProcessBuilder) with respect to maximum path lengths, we need to get the
short path name for any native controllers before trying to start them
in case the absolute path exceeds the maximum path length. This commit
uses JNA to invoke the necessary Windows API for this to start the
native controller using the short path.
To be precise about the limitation here, the MSDN docs for
CreateProcessW say for the command line parameter:
>The command line to be executed. The maximum length of this string is
>32,768 characters, including the Unicode terminating null character. If
>lpApplicationName is NULL, the module name portionof lpCommandLine is
>limited to MAX_PATH characters.
This is exactly how the Windows implementation of Process in the JDK
invokes CreateProcessW: with the executable name (lpApplicationName) set
to NULL.

Most notable changes:
- better update concurrency: LUCENE-7868
- TopDocs.totalHits is now a long: LUCENE-7872
- QueryBuilder does not remove the boolean query around multi-term synonyms:
LUCENE-7878
- removal of Fields: LUCENE-7500
For the `TopDocs.totalHits` change, this PR relies on the fact that the encoding
of vInts and vLongs are compatible: you can write and read with any of them as
long as the value can be represented by a positive int.
The `document_type` parameter is no longer required to be specified,
because by default from 6.0 only a single type is allowed. (`index.mapping.single_type` defaults to `true`)
Bringing together shards in a shrunken index means that we need to
address the start of history for the shrunken index. The problem here is
that sequence numbers before the maximum of the maximum sequence numbers
on the source shards can collide in the target shards in the shrunken
index. To address this, we set the maximum sequence number and the local
checkpoint on the target shards to this maximum of the maximum sequence
numbers. This enables correct document-level semantics for documents
indexed before the shrink, and history on the shrunken index will
effectively start from here.

MockTransportServices allows us to simulate network disruptions in our testing infra. Sadly it wasn't updated to the state of the art in Transport land. This PR brings it up to speed. Specifically:
1) Opening a connection is now also blocked (before only node connections were blocked)
2) Simplifies things using the latest connection based notification between TcpTransport and TransportService for when a disconnect happens.
3) By 2, it fixes a race condition where we may fail to respond to a sent request when it is sent concurrently with the closing of a connection. The old code relied on a node based bridge between tcp transport and transport service. Sadly, the following doesn't work any more:
```
if (transport.nodeConnected(node)) {
// this a connected node, disconnecting from it will be up the exception
transport.disconnectFromNode(node); <-- this may now be a noop and it doesn't mean that the transport service was notified of the disconnect between the nodeConnected check and here.
} else {
throw new ConnectTransportException(node, reason, e);
}
```
This setting is supposed to ease index upgrades as it allows you
to check for a new setting called `index.internal.version` which
can be used to check before upgrading indices.
If secure settings are closed after the node has been constructed
no key-store access is permitted. We should also try to be as close as possible
to the real behavior if we mock secure settings. This change also adds
the same behavior as bootstrap has to InternalTestCluster to ensure we fail
if we try to read from secure settings after the node has been constructed.
Today when an index is shrunk, the primary terms for its shards start
from one. Yet, this is a problem as the index will already contain
assigned sequence numbers across primary terms. To ensure document-level
sequence number semantics, the primary terms of the target shards must
start from the maximum of all the shards in the source index. This
commit causes this to be the case.

In MockFSDirectory we should use the actual indexes settings to build
a new IndexMetaData settings object instead of the node settings.

I'm still trying to hunt down rare failures in the cancelation tests
for reindex and friends. Here is the latest:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=ubuntu/876/console
It doesn't show much, other than that one of the tasks didn't kill
itself when asked to cancel.
So I'm going a bit crazy with debug logging so that the next time this
comes up I can trace exactly what happened.
Additionally, this tweaks the logic around how rethrottles were
performed around cancel. Previously we set the `requestsPerSecond`
to `0` when we cancelled the task. That was the "old way" to set them
to inifity which was the intent. This switches that from `0` to
`Float.MAX_VALUE` which is the "new way" to set the `requestsPerSecond`
to infinity. I don't know that this is much better, but it feels better.
In tests, we sometimes create a random directory service and as part of that the IndexSettings get
built again. When we build them again, we need to make sure we do not set the secure settings on
the new IndexMetaData object that gets created as the node settings already have the secure
settings and the index settings and node settings will be combined. If both have secure settings,
the settings builder will throw an AlreadySetException.
This commit fixes a typo in the KeyStoreCli class. The add-file command was incorrectly set to use
the AddStringKeyStoreCommand instead of the AddFileKeyStoreCommand.
Indexing or deleting documents through the IndexShard interface is quite complex and error-prone. It requires multiple calls, e.g. first prepareIndexOnPrimary, then do some checks if mapping updates have occurred, then do the actual indexing using index(...) etc. Currently each consumer of the interface (local recovery, peer recovery, replication) has additional custom checks built around it to deal with mapping updates, some of which are even inconsistent. This commit aims at reducing the complexity by exposing a simpler interface on IndexShard. There are no more prepare*** methods and the mapping complexity is also hidden, but still giving callers a possibility to implement custom logic to deal with mapping updates.
This commit changes the parsing logic of DocWriteResponse, ReplicationResponse
and GetResult so that it skips any unknown additional fields (for forward compatibility
reasons). This affects the IndexResponse, UpdateResponse,DeleteResponse and
GetResponse objects.
Today we maintain a map of open connections in order to close them when
a low level channel gets closed or handles a failure. We also spawn a thread due to some
tricky concurrency issues especially with respect to netty since they listener might
be called on a transport / boss thread. Executions on those threads must not be blocking
since otherwise we will likely deadlock the event processing which adds to the
complexity of the concurrency model in this class.
This change associates the connection with the close callback that every channel invokes
once it's closed which allows us to remove the connections map. A relaxed non-blocking
concurrency model in the connection close listener allows cleaning up connected nodes without
blocking on any lock.
