This commit creates TemplateScript and associated classes so that
templates no longer need a special ScriptService.compileTemplate method.
The execute() method is equivalent to the old run() method.
relates #20426
* All public methods starting with get will be added as local variables
to the execute method.
* The execute method on a ScriptContext must be both public and
abstract. This method will be implemented by the Painless compiler.
* A static list of parameter names for the execute method must be
provided since the names will be eliminated at runtime.
* The uses$ methods will still be implemented as before.
* A single constructor may be provided by the ScriptContext. This
constructor will be overridden by the Painless compiler to include the
exact same arguments. This allows instances of a Painless script to
potentially contain state. If a constructor is not provided it is
assumed the default constructor with no arguments will be used.
This removes the `accumulateExceptions()` method (and its usage) from `TransportNodesAction` and `TransportTasksAction`, forcing both transport actions to always accumulate exceptions.
Without this change, some transport actions, like `TransportNodesStatsAction` would respond in very unexpected ways by returning no response due to some failure, but instead of returning an
error the response would simply be empty: no response and no error.
This results in a very trappy response structure where users can check for an error, then attempt to blindly use the response when no error is returned.
* Adds nodes usage API to monitor usages of actions
The nodes usage API has 2 main endpoints
/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics
for all nodes and the specified node(s) respectively.
At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.
Still to do:
* [x] Create usage service to store usage statistics
* [x] Record usage in REST layer
* [x] Add Transport Actions
* [x] Add REST Actions
* [x] Tests
* [x] Documentation
* Rafactors UsageService so counts are done by the handlers
* Fixing up docs tests
* Adds a name to all rest actions
* Addresses review comments
This change ensures that there is a single parent-join field defined per mapping.
The verification is done through the addition of a special field mapper (MetaJoinFieldMapper) with a unique name (_parent_join) that is registered to the mapping service
when the first parent-join field is defined. If a new parent-join is added, this field mapper will clash with the new one and the update will fail.
This change also simplifies the parent join fetch sub phase by retrieving the parent-join field without iterating on all fields in the mapping.
This commit adds an optional `context` url parameter to the put stored
script request. When a context is specified, the script is compiled
against that context before storing, as a validation the script will
work when used in that context.
* Introduce ParentJoinFieldMapper, a field mapper that creates parent/child relation within documents of the same index
This change adds a new field mapper named ParentJoinFieldMapper. This mapper is a replacement for the ParentFieldMapper but instead of using the types in the mapping
it uses an internal field to materialize parent/child relation within a single index.
This change also adds a fetch sub phase that automatically retrieves the join name (parent or child name) and the parent id for child documents in the response hit fields.
The compatibility with `has_parent`, `has_child` queries and `children` agg will be added in a follow up.

ScriptContexts currently understand a FactoryType that can produce
instances of the script InstanceType. However, for search scripts, this
does not work as we have the concept of LeafSearchScript that is created
per lucene segment. This commit effectively renames the existing
SearchScript class into SearchScript.LeafFactory, which is a new,
optional, class that can be defined within a ScriptContext.
LeafSearchScript is effectively renamed back into SearchScript. This
change allows the model of stateless factory -> stateful factory ->
script instance to continue, but in a generic way that any script
context may take advantage of.

DateProcessor's DateFormat UNIX format parser resulted in
a floating point rounding error when parsing certain stringed
epoch times. Now Double.parseDouble is used, preserving the
intented input.
This commit adds a `doc_count` field to the response body of Matrix
Stats aggregation. It exposes the number of documents involved in
the computation of statistics, a value that can already be retrieved using
the method MatrixStats.getDocCount() in the Java API.
Removes the need for the `_UNRELEASED` suffix on versions by detecting if a version should be unreleased or not based on the versions around it. This should make it simpler to automate the task of adding a new version label.
This commit renames the concept of the "compiled type" to a "factory
type", along with all implementations of this class to be named Factory.
This brings it inline with the classes purpose.
This commit adds collection of all contexts to the parameters of
getScriptEngine. This will allow script engines like painless to
precache extra information about the contexts.
This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
This commit changes the compile method of ScriptEngine to be generic in
the same way it is on ScriptService. This moves the shim of handling the
two existing context classes into each script engine, so that each
engine can be worked on independently to convert to real handling of
contexts.
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.
Since groovy was removed, we no longer have any ScriptEngines with
resources to release. We may want to keep the option open for a script
engine to close resources, but this would not be common. This commit
adds a default implementation to ScriptEngine for `close()` to reduce
the boiler plate that must be added for a ScriptEngine implementation.
This will be useful for the high level client to add support for the matrix stats aggregation, as we will ship with this jar by default like we do for parent-join-client which is aligned with distributing core with the modules already included.

This commit moves the handling of nested and parent/child inner hits to specialized classes that can be defined outside of ES core.
InnerHitBuilderContext is now used by the parent query (nested or hasChild, ...) to build the sub context from the InnerHitBuilder definition.
BWC is also ensured so that nodes in previous versions can still send/receive inner hits to/from this version.

As we work towards contexts implying the return type of compilation, we
first need ScriptContext to not be an enum. This commit removes the
Standard enum and Plugin subclass of ScriptContext.
ScriptEngine implementations have an overridable method to indicate they
are safe to use as inline scripts. Since groovy was removed fro 6.0,
there are no longer any implementations which used the default false
value. Furthermore, the value was not actually read anywhere. This
commit removes the method. The ScriptEngineRegistry was also no longer
necessary as it only was used to build a map from language to engine.
Allows plugins to register pre-configured tokenizers. Much
of the decisions are the same as those in #24223, #24572,
and #24223. This only migrates the lowercase tokenizer but
I figure that is a good start because it proves out the features.
This change removes the field data specialization needed for the parent field and replaces it with
a simple DocValuesIndexFieldData. The underlying global ordinals are retrieved via a new function called
IndexOrdinalsFieldData#getOrdinalMap.
The children aggregation is also modified to use a simple WithOrdinals value source rather than the deleted WithOrdinals.Parent.

Shared settings were added intially to allow the few common settings
names across aws plugins. However, in 6.0 these settings have been
removed. The last use was in netty, but since 6.0 also has the netty 3
modules removed, there is no longer a need for the shared property. This
commit removes the shared setting property.
Approaching the release of 6.0 we need to sort out the usage of
`Version#minimumCompatibilityVersion` which was still set to 5.0.0.
Now this change moves it to the latest released version of 5.x (5.4 at this point)
to ensure we are compatible with the latest minor of the previous major. This change
also removes all the `_UNRELEASED` from the versions that where released and drops versions
that were never released and are not expected to be released (bugfixes in minors that are not
the latest in the previous major).
We've switched to supporting only `yml` files but anyone who didn't
notice will commit a `yaml` file which won't be executed
which is bad because it is easy not to notice. The test to catch this is
simple enough that I think it is worth adding just to warn folks about
their mistake.
These tests are broken because I added them with the `yml` extension
and didn't realize that we weren't running tests with that extension
until we merged #24659. I used that extension in anticipation of #24659
but didn't verify that the tests were actually running. Ooops!
Closes#24734
This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
Moves the remaining preconfigured token figured into the analysis-common module. There were a couple of tests in core that depended on the pre-configured token filters so I had to touch them:
* `GetTermVectorsCheckDocFreqIT` depended on `type_as_payload` but didn't do anything important with it. I dropped the dependency. Then I moved the test to a single node test case because we're trying to cut down on the number of `ESIntegTestCase` subclasses.
* `AbstractTermVectorsTestCase` and its subclasses depended on `type_as_payload`. I dropped their usage of the token filter and added an integration test for the termvectors API that uses `type_as_payload` to the `analysis-common` module.
* `AnalysisModuleTests` expected a few pre-configured token filtes be registered by default. They aren't any more so I dropped this assertion. We assert that the `CommonAnalysisPlugin` registers these pre-built token filters in `CommonAnalysisFactoryTests`
* `SearchQueryIT` and `SuggestSearchIT` had tests that depended on the specific behavior of the token filters so I moved the tests to integration tests in `analysis-common`.
Today when an index is `read-only` the index is also blocked from
being deleted which sometimes is undesired since in-order to make
changes to a cluster indices must be deleted to free up space. This is
a likely scenario in a hosted environment when disk-space is limited to switch
indices read-only but allow deletions to free up space.
Range queries with now based date ranges were previously not allowed,
but since #23921 these queries were allowed. This change should really
fix range queries with now based date ranges.
Template script engines (mustache, the only one) currently return a
BytesReference that users must know is utf8 encoded. This commit
modifies all callers and mustache to have the template engine return
String. This is much simpler, and does not require decoding in order to
use (for example, in ingest).
Netty removed a logging guarded we added to prevent a scary logging
message. We added a hack to work around this. They've added the guard
back, so we can remove the hack now.
When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.

* Add parent-join module
This change adds a new module named `parent-join`.
The goal of this module is to provide a replacement for the `_parent` field but as a first step this change only moves the `has_child`, `has_parent` queries and the `children` aggregation to this module.
These queries and aggregations are no longer in core but they are deployed by default as a module.

Today we prune transport handlers in TransportService when a node is disconnected.
This can cause connections to starve in the TransportService if the connection is
opened as a short living connection ie. without sharing the connection to a node
via registering in the transport itself. This change now moves to pruning based
on the connections cache key to ensure we notify handlers as soon as the connection
is closed for all connections not just for registered connections.

This commit renames ScriptEngineService to ScriptEngine. It is often
confusing because we have the ScriptService, and then
ScriptEngineService implementations, but the latter are not services as
we see in other places in elasticsearch.
This changes the way we register pre-configured token filters so that
plugins can declare them and starts to move all of the pre-configured
token filters out of core. It doesn't finish the job because doing
so would make the change unreviewably large. So this PR includes
a shim that keeps the "old" way of registering pre-configured token
filters around.
The Lowercase token filter is special because there is a "special"
interaction between it and the lowercase tokenizer. I'm not sure
exactly what to do about it so for now I'm leaving it alone with
the intent of figuring out what to do with it in a followup.
This also renames these pre-configured token filters from
"pre-built" to "pre-configured" because that seemed like a more
descriptive name.
This is a part of #23658
In pre-release versions of Elasticsearch 5.0.0, users were subject to
log messages of the form "your platform does not.*reliably.*potential
system instability". This is because we disable Netty from being unsafe,
and Netty throws up this scary info-level message when unsafe is
unavailable, even if it was unavailable because the user requested that
it be unavailabe. Users were rightly confused, and concerned. So, we
contributed a guard to Netty to prevent this log message from showing up
when unsafe was explicitly disabled. This guard shipped with all
versions of Netty that shipped starting with Elasticsearch
5.0.0. Unfortunately, this guard was lost in an unrelated refactoring
and now with the 4.1.10.Final upgrade, users will again see this
message. This commit is a hack around this until we can get a fix
upstream again.

This change makes the request builder code-path same as `Client#execute`. The request builder used to return a `ListenableActionFuture` when calling execute, which allows to associate listeners with the returned future.

This also adds the flag when running tests and adapts some tests

Netty uses the number of processors for sizing various resources (e.g.,
thread pools, buffer pools, etc.). However, it uses the runtime number
of available processors which might not match the configured number of
processors as set in Elasticsearch to limit the number of threads (for
example, in Docker containers). A new feature was added to Netty that
enables configuring the number of processors Netty should see for sizing
this various resources. This commit takes advantage of this feature to
set this number of available processors to be equal to the configured
number of processors set in Elasticsearch.

The one argument ctor for `Script` creates a script with the
default language but most usages of are for testing and either
don't care about the language or are for use with
`MockScriptEngine`. This replaces most usages of the one argument
ctor on `Script` with calls to `ESTestCase#mockScript` to make
it clear that the tests don't need the default scripting language.
I've also factored out some copy and pasted script generation
code into a single place. I would have had to change that code
to use `mockScript` anyway, so it was easier to perform the
refactor.

Another step down the road to dropping the
lucene-analyzers-common dependency from core.
Note that this removes some tests that no longer compile from
core. I played around with adding them to the analysis-common

the tests generated from the example usage in the documentation.
I'm not super happy with the way that `requriesAnalysisSettings`
works with regards to plugins. I think it'd be fairly bug-prone
for plugin authors to use. But I'm making it visible as is for
now and I'll rethink later.

The percolator doesn't close the IndexReader of the memory index any more.
Prior to 2.x the percolator had its own SearchContext (PercolatorContext) that did this,
but that was removed when the percolator was refactored as part of the 5.0 release.
I think an alternative way to fix this is to let percolator not use the bitset and fielddata caches,
that way we prevent the memory leak.

Replaces LambdaMetaFactory with LambdaBootstrap, a custom solution for lambdas in Painless using a design similar to LambdaMetaFactory, but allows for custom adaptation of types which recent changes to LambdaMetaFactory no longer allowed.
ScriptService has two executable methods, one which takes a
CompiledScript, which is similar to search, and one that takes a raw
Script and both compiles and returns an ExecutableScript for it. The
latter is not needed, and the call sites which used one or the other
were mixed. This commit removes the extra executable method in favor of
callers first calling compile, then executable.
The unwrap method was leftover from support javascript and python. Since
those languages are removed in 6.0, this commit removes the unwrap
feature from scripts.
Start moving built in analysis components into the new analysis-common
module. The goal of this project is:
1. Remove core's dependency on lucene-analyzers-common.jar which should
shrink the dependencies for transport client and high level rest client.
2. Prove that analysis plugins can do all the "built in" things by moving all
"built in" behavior to a plugin.
3. Force tests not to depend on any oddball analyzer behavior. If tests
need anything more than the standard analyzer they can use the mock
analyzer provided by Lucene's test infrastructure.
`script_stack` is super useful when debugging Painless scripts
because it skips all the "weird" stuff involved that obfuscates
where the actual error is. It skips Painless's internals and
call site bootstrapping.
It works fine, but it didn't have many tests. This converts a
test that we had for line numbers into a test for the
`script_stack`. The line numbers test was an indirect test
for `script_stack`.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

We'd like to be able to support context-sensitive whitelists in
Painless but we can't now because the whitelist is a static thing.
This begins to de-static the whitelist, in particular removing
the static keyword from most of the methods on `Definition` and
plumbing the static instance into the appropriate spots as though
it weren't static. Once we de-static all the methods we should be
able to fairly simply build context-sensitive whitelists.
The only "fun" bit of this is that I added another layer in the
chain of methods that bootstraps `def` calls. Instead of running
`invokedynamic` directly on `DefBootstrap` we now `invokedynamic`
`$bootstrapDef` on the script itself loads the `Definition` that
the script was compiled against and then calls `DefBootstrap`.
I chose to put `Definition` into `Locals` so I didn't have to
change the signature of all the `analyze` methods. I could have
do it another way, but that seems ok for now.
We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge
The JVM caches `Integer` objects. This is known. A test in Painless
was relying on the JVM not caching the particular integer `1000`.
It turns out that when you provide `-XX:+AggressiveOpts` the JVM
*does* cache `1000`, causing the test to fail when that is
specified.
This replaces `1000` with a randomly selected integer that we test
to make sure *isn't* cached by the JVM. *Hopefully* this test is
good enough. It relies on the caching not changing in between when
we check that the value isn't cached and when we run the painless
code. The cache now is a simple array but there is nothing
preventing it from changing. If it does change in a way that thwarts
this test then the test fail fail again. At least when that happens
the next person can see the comment about how it is important
that the integer isn't cached and can follow that line of inquiry.

When indexing a document via the bulk API where IDs can be explicitly
specified, we currently accept an empty ID. This is problematic because
such a document can not be obtained via the get API. Instead, we should
rejected these requets as accepting them could be a dangerous form of
leniency. Additionally, we already have a way of specifying
auto-generated IDs and that is to not explicitly specify an ID so we do
not need a second way. This commit rejects the individual requests where
ID is specified but empty.

This commit makes closing a ReleasableBytesStreamOutput release the underlying BigArray so
that we can use try-with-resources with these streams and avoid leaking memory by not returning
the BigArray. As part of this change, the ReleasableBytesStreamOutput adds protection to only
release the BigArray once.
In order to make some of the changes cleaner, the ReleasableBytesStream interface has been
removed. The BytesStream interface is changed to a abstract class so that we can use it as a
useable return type for a new method, Streams#flushOnCloseStream. This new method wraps a
given stream and overrides the close method so that the stream is simply flushed and not closed.
This behavior is used in the TcpTransport when compression is used with a
ReleasableBytesStreamOutput as we need to close the compressed stream to ensure all of the data
is written from this stream. Closing the compressed stream will try to close the underlying stream
but we only want to flush so that all of the written bytes are available.
Additionally, an error message method added in the BytesRestResponse did not use a builder
provided by the channel and instead created its own JSON builder. This changes that method to use
the channel builder and in turn the bytes stream output that is managed by the channel.
Note, this commit differs from 6bfecdf921 in that it updates
ReleasableBytesStreamOutput to handle the case of the BigArray decreasing in size, which changes
the reference to the BigArray. When the reference is changed, the releasable needs to be updated
otherwise there could be a leak of bytes and corruption of data in unrelated streams.

Otherwise the execution happens asynchronously.

withSyncBackoff and withAsyncBackoff have been replaced with two
versions of withBackoff. One method takes a listener that will be

The getProperty method is an internal method needed to run pipeline aggregations and retrieve info by path from the aggs tree. It is not needed in the MultiBucketsAggregation.Bucket interface, which is returned to users running aggregations from the transport client.

reindex_from_remote was using `TimeValue#toString` to generate the

time values that are useful for people but bad for Elasticsearch
which doesn't like to parse them. This switches it to using
`TimeValue#getStringRep` which spits out whole time values.

Makes #23828 even more desirable
Before now ranges where forbidden, because the percolator query itself could get cached and then the percolator queries with now ranges that should no longer match, incorrectly will continue to match.
By disabling caching when the `percolator` is being used, the percolator can now correctly support range queries with now based ranges.
I think this is the right tradeoff. The percolator query is likely to not be the same between search requests and disabling range queries with now ranges really disabled people using the percolator for their use cases.
Also fixed an issue that existed in the percolator fieldmapper, it was unable to find forbidden queries inside `dismax` queries.

The current rest backcompat tests, which run against a mixed cluster of
5.x and 6.0 nodes, depend on snapshot builds of 5.x. However, this has
the potential for inconsistency that results in CI failures, and happens

builds the zip distribution, and ties that into gradle substitutions for
the 5.x version.
Removed `parse(String index, String type, String id, BytesReference source)` in DocumentMapper.java and replaced all of its use in Test files with `parse(SourceToParse source)`.
`parse(String index, String type, String id, BytesReference source)` was only used in test files and never in the main code so it was removed. All of the test files that used it was then modified to use `parse(SourceToParse source)` method that existing in DocumentMapper.java
Without this change, if write a script with multiple regexes
*sometimes* the lexer will decide to look at them like one
big regex and then some trailing garbage. Like this discuss post:
https://discuss.elastic.co/t/error-with-the-split-function-in-painless-script/79021
```
def val = /\\\\/.split(ctx._source.event_data.param17);
if (val[2] =~ /\\./) {
def val2 = /\\./.split(val[2]);
ctx._source['user_crash'] = val2[0]
} else {
ctx._source['user_crash'] = val[2]
}
```
The error message you get from the lexer is `lexer_no_viable_alt_exception`
right after the *second* regex.
With this change each regex is just a single regex like it ought to be.
As a bonus, while looking into this issue I found that the error
reporting for regexes wasn't very nice. If you specify an invalid
pattern then you get an error marker on the start of the pattern
with the JVM's regex error message which attempts to point you to the
location in the regex but is totally unreadable in the JSON response.
This change fixes the location to point to the appropriate spot
inside the pattern and removes the portion of the JVM's error message
that doesn't render well. It is no longer needed now that we point
users to the appropriate spot in the pattern.
Changes reindex and friends to wait until the entire request has
been "cleaned up" before responding. "Clean up" in this context
is clearing the scroll and (for reindex-from-remote) shutting
down the client. Failures to clean up are still only logged, not
returned to the user.
Closes#23653
This commit upgrades the Netty dependencies from version 4.1.8 to
version 4.1.9. This commit picks up a few bug fixes that impacted us:
- Netty was incorrectly ignoring interfaces with self-assigned MAC
addresses (e.g., instances running in Docker containers or on EC2)
- incorrect handling of the Expect: 100-continue header
Relates #23540
With this commit we change the default receive predictor size for Netty
from 32kB to 64kB as our testing has shown that this leads to less
allocations on smaller heaps like the default out of the box
configuration and this value also works reasonably well for larger
heaps.
Closes#23185
This commit mutes a ton of Painless lambda tests on JDK 9. This commit
did not attempt to discover exactly which tests are failing, but instead
just blanket muted all tests in LambdaTests, FunctionRefTests, and
AugmentationTests.
Relates #23473
Previously, the RestController would stash the context prior to copying headers. However, there could be deprecation
log messages logged and in turn warning headers being added to the context prior to the stashing of the context. These
headers in the context would then be removed from the request and also leaked back into the calling thread's context.
This change moves the stashing of the context to the HttpTransport so that the network threads' context isn't
accidentally populated with warning headers and to ensure the headers added early on in the RestController are not
excluded from the response.
Throw error when skip or do sections are malformed, such as they don't start with the proper token (START_OBJECT). That signals bad indentation, which would be ignored otherwise. Thanks (or due to) our pull parsing code, we were still able to properly parse the sections, yet other runners weren't able to.
Closes#21980

We have many version constants in master that have already been
released, but are still marked (by naming convention) as unreleased.
This commit renames those version constants.
The dependencyLicenses check has the ability to map multiple jar files
to the same license file. However, netty was not taking advantage of
this, and had duplicate copies of its license/notice files for each jar.
This commit reduces the copies to one and uses the mapping feature.
This commit sets the intial size of the pipeline handler queue small to
prevent waste if pipelined requests are never sent. Since the queue will
grow quickly if pipeline requests are indeed set, this should not be
problematic.
Relates #23335
When pipelined responses are sent to the pipeline handler for writing,
they are not necessarily written immediately. They must be held in a
priority queue until all responses preceding the given response are
written. This means that when write is invoked on the handler, the
promise that is attached to the write invocation will not necessarily be
the promise associated with the responses that are written while the
queue is drained. To address this, the promise associated with a
pipelined response must be held with the response and then used when the
channel context is actually written to. This was introduced when
ensuring that the releasing promise is always chained through on write
calls lest the releasing promise never be invoked. This leads to many
failing test cases, so no new test cases are needed here.
Relates #23317
Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
When sending a response to a client, we attach a releasing listener to
the channel promise. If the client disappears before the response is
sent, the releasing listener was never notified. The reason the
listeners were never notified was due to a mistaken invocation of write
and flush on the channel which has two overrides: one that takes an
existing promise, and one that does not and instead creates a new
promise. When the client disappears, it is this latter promise that is
notified, which does not contain the releasing listener. This commit
addreses this issue by invoking the override that passes our channel
promise through.

Now that search templates always get converted to json, we don't need to try and auto-detect their content-type, which anyways didn't work as expected before given that only json was really working.
