This commit fixes responses to HEAD requests so that the value of the
Content-Length is correct per the HTTP spec. Namely, the value of this
header should be equal to the Content-Length if the request were not a
HEAD request.
This commit also fixes a memory leak on HEAD requests to the main action
that arose from the bytes on a builder not being released due to them
being dropped on the floor to ensure that the response to the main
action did not have a body.

Versions before 2.0 needed to be told to return interesting fields
like `_parent`, `_routing`, `_ttl`, and `_timestamp`. And they come
back inside a `fields` block which we need to parse.

This allows you to whitelist `localhost:*` or `127.0.10.*:9200`.
It explicitly checks for patterns like `*` in the whitelist and
refuses to start if the whitelist would match everything. Beyond
that the user is on their own designing a secure whitelist.
When running `gradle run`, a developer usually intends to get a running
instance as if they had run elasticsearch from the command line. This is
different than the isolated environment we use for integration testing
plugins. This change switches the run task to use the zip distribution,
so that all modules included in the normal distribution are included.
* Scripting: Add support for booleans in scripts
Since 2.0, booleans have been represented as numeric fields (longs).
However, in scripts, this is odd, since you expect doing a comparison
against a boolean to work. While languages like groovy will auto convert
between booleans and longs, painless does not.
This changes the doc values accessor for boolean fields in scripts to
return Boolean objects instead of Long objects.

* Make Booleans final and remove wrapping of `this` for getValues()
This commit fixes an issue with the handling of the value "keep-alive"
on the Connection header in the Netty 4 HTTP implementation while
handling an HTTP 1.0 request. The issue was using the wrong equals
method to compare an AsciiString instance and a String instance (they
could never be equal). This commit fixes this to use the correct equals
method to compare for content equality.

Today Elasticsearch limits the number of processors used in computing
thread counts to 32. This was from a time when Elasticsearch created
more threads than it does now and users would run into out of memory
errors. It appears the real cause of these out of memory errors was not
well understood (it's often due to ulimit settings) and so users were
left hitting these out of memory errors on boxes with high core
counts. Today Elasticsearch creates less threads (but still a lot) and
we have a bootstrap check in place to ensure that the relevant ulimit is
not too low.
There are some caveats still to having too many concurrent indexing
threads as it can lead to too many little segments, and it's not a
magical go faster knob if indexing is already bottlenecked by disk, but
this limitation is artificial and surprising to users and so it should
be removed.
This commit also increases the lower bound of the max processes ulimit,
to prepare for a world where Elasticsearch instances might be running
with more the previous cap of 32 processors. With the current settings,
Elasticsearch wants to create roughly 576 + 25 * p / 2 threads, where p
is the number of processors. Add in roughly 7 * p / 8 threads for the GC
threads and a fudge factor, and 4096 should cover us pretty well up to
256 cores.

Both netty3 and netty4 http implementation printed the default

This commit adds a better default toString method to PortRange and
uses the string representation for the error message in the http

Some objects like maps, iterables or arrays of objects can self-reference themselves. This is mostly due to a bug in code but the XContentBuilder should be able to detect such situations and throws an IllegalArgumentException instead of building objects over and over until a stackoverflow occurs.

Update scripts might want to update the documents `_timestamp` but need a notion of `now()`.
Painless doesn't support any notion of now() since it would make scripts non-pure functions. Yet,
in the update case this is a valid value and we can pass it with the context together to allow the
script to record the timestamp the document was updated.

Today we throw an assertion error if we release an AbstractArray more than once.
Yet, it's recommended to implement close methods such that they can be invoked
more than once. Guaranteed single release calls are hard to implement and some

Move ClusterSettings to nullable ctor parameter of TransportService
so it isn't forgotten.
This change proposes the removal of all non-tcp transport implementations. The
mock transport can be used by default to run tests instead of local transport that has
roughly the same performance compared to TCP or at least not noticeably slower.
This is a master only change, deprecation notice in 5.x will be committed as a
separate change.
Today SearchContext expose the current context as a thread local which makes any kind of sane interface design very very hard. This PR removes the thread local entirely and instead passes the relevant context anywhere needed. This simplifies state management dramatically and will allow for a much leaner SearchContext interface down the road.
Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

Today we hold on to all possible tokenizers, tokenfilters etc. when we create
an index service on a node. This was mainly done to allow the `_analyze` API to
directly access all these primitive. We fixed this in #19827 and can now get rid of
the AnalysisService entirely and replace it with a simple map like class. This
ensures we don't create a gazillion long living objects that are entirely useless since
they are never used in most of the indices. Also those objects might consume a considerable
amount of memory since they might load stopwords or synonyms etc.

This commit removes `ByteSizeValue`'s methods that are duplicated (ex: `mbFrac()` and `getMbFrac()`) in order to only keep the `getN` form.

* Build: Remove old maven deploy support
This change removes the old maven deploy that we have in parallel to
maven-publish, and makes maven-publish fully work with publishing to
maven local. Using `gradle publishToMavenLocal` should be used to
publish to .m2.
Note that there is an unfortunate hack that means for
zip artifacts we must first create/publish a dummy pom file, and then
follow that with the real pom file. It would be nice to have the pom
file contains packaging=zip, but maven central then requires sources and
javadocs. But our zips are really just attached artifacts, so we already
set the packaging type to pom for our zip files. This change just works
around a limitation of the underlying maven publishing library which
silently skips attached artifacts when the packaging type is set to pom.

* Remove unnecessary extra spacing
This change removes all guice interaction from Transport, HttpServerTransport,
HttpServer and TransportService. All these classes as well as their subclasses
or extended version configured via plugins are now created by using plain old
bloody java constructors. YAY!
We can now run templates using `explain` and/or `profile` parameters.
Which is interesting when you have defined a complicated profile but want to debug it in an easier way than running the full query again.
You can use `explain` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"explain": true
}
```
You can use `profile` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"profile": true
}
```
TransportService is such a central part of the core server, replacing
it's implementation is risky and can cause serious issues. This change removes the ability to
plug in TransportService but allows registering a TransportInterceptor that enables
plugins to intercept requests on both the sender and the receiver ends. This is a commonly used
and overwritten functionality but encapsulates the custom code in a contained manner.
This change replaces the fields parameter with stored_fields when it makes sense.
This is dictated by the renaming we made in #18943 for the search API.
The following list of endpoint has been changed to use `stored_fields` instead of `fields`:
* get
* mget
* explain
The documentation and the rest API spec has been updated to cope with the changes for the following APIs:
* delete_by_query
* get
* mget
* explain
The `fields` parameter has been deprecated for the following APIs (it is replaced by _source filtering):
* update: the fields are extracted from the _source directly.
* bulk: the fields parameter is used but fields are extracted from the source directly so it is allowed to have non-stored fields.
Some APIs still have the `fields` parameter for various reasons:
* cat.fielddata: the fields paramaters relates to the fielddata fields that should be printed.
* indices.clear_cache: used to indicate which fielddata fields should be cleared.
* indices.get_field_mapping: used to filter fields in the mapping.
* indices.stats: get stats on fields (stored or not stored).
* termvectors: fields are retrieved from the stored fields if possible and extracted from the _source otherwise.
* mtermvectors:
* nodes.stats: the fields parameter is used to concatenate completion_fields and fielddata_fields so it's not related to stored_fields at all.

** In the aggregation parsing code added `ParserContext` that also holds the default scripting language like `QueryParseContext`. Most parser don't have access to `QueryParseContext`. This is for scripts in aggregations.

4) and Netty 4. This commit updates these tests to reverse the role of
Netty 3 and Netty 4 so that the randomization is choosing between Netty

The Netty 4 HTTP server pipeline tests contains two different test
cases. The general idea behind these tests is to submit some requests to
a Netty 4 HTTP server, one test with pipelining enabled and another test
with pipelining disabled. These requests are submitted to two endpoints,
one with a path like /{id} and another with a path like /slow with a
query string parameter sleep. This parameter tells the request handler
how long to sleep for before replying. The idea is that in the case of
the pipelining enabled tests, the requests should come back exactly in
the order submitted, even with some of the requests hitting the slow
endpoint with random sleep durations; this is the guarantee that
pipelining provides. And in the case of the pipelining disabled tests,
requests were randombly submitted to /{id} and /slow with sleep
parameters starting at 600ms and increasing by 100ms for each slow
request constructed. We would expect the requests to come back with the
all the responses to the /{id} requests first because these requests
will execute instantaneously, and then the responses to the /slow
requests. Further, it was expected that the slow requests would come
back ordered by the length of the sleep, the thinking being that 100ms
should be enough of a difference between each request that we would
avoid any race conditions. Sadly, this is not the case, the threads do
sometimes hit race conditions.
This commit modifies the HTTP server pipelining tests to address this
race condition. The modification is that the query string parameter on
the /slow endpoint is removed in favor of just submitting requests to
the path /slow/{id}, where id just used a marker to distinguish each
request. The server chooses a random sleep of at least 500ms for each
request on the slow path. The assertion here then is that the /{id}
responses arrive first, then then /slow responses. We can not make an
assertion on the order of the responses, but we can assert that we did
see every expected response.

This change adds a special field named _none_ that allows to disable the retrieval of the stored fields in a search request or in a TopHitsAggregation.

POST _search
{
"stored_fields": "_none_"

Currently, bulk item requests can be any ActionRequest, this commit
restricts bulk item requests to DocumentRequest. This simplifies
handling failures during bulk requests. Additionally, a new enum
is added to DocumentRequest to represent the intended operation
to be performed by a document request. Now, index operation type
also uses the new enum to specify whether the request should
create or index a document.
Reindex intentionally tries to fail the search operation to make sure
that the exception flows back. The exception message changed so we
should catch the appropriate exception.
This test was failing in the presence of transport clients. This turns
off transport clients while I fix the test so it doesn't fail for
everyone in the mean time.
The big change here is cleaning up the `TaskListResponse` so it doesn't
have a breaky `toString` implementation. That was causing the reindex
tests to break.
Also removed `NetworkModule#registerTaskStatus` which is part of the
Plugin API. Use `Plugin#getNamedWriteables` instead.
Parsing a search request is currently split up among a number of
classes, using multiple public static methods, which take multiple
regstries of elements that may appear in the search request like query
parsers and aggregations. This change begins consolidating all this code
by collapsing the registries normally used for parsing search requests
into a single SearchRequestParsers class. It is also made available to
plugin services to enable templating of search requests. Eventually all
of the actual parsing logic should move to the class, and the registries
should be hidden, but for now they are at least co-located to reduce the
number of objects that must be passed around.
Squashes all the subpackages of `org.elasticsearch.rest.action` down to
the following:
* `o.e.rest.action.admin` - Administrative actions
* `o.e.rest.action.cat` - Actions that make tables for `grep`ing
* `o.e.rest.action.document` - Actions that act on documents
* `o.e.rest.action.ingest` - Actions that act on ingest pipelines
* `o.e.rest.action.search` - Actions that search
I'm tempted to merge `search` into `document` but the `document`
package feels fairly complete as is and `Suggest` isn't actually always
about documents either....
I'm also tempted to merge `ingest` into `admin.cluster` because the
latter contains the actions for dealing with stored scripts.
I've moved the `o.e.rest.action.support` into `o.e.rest.action`.
I've also added `package-info.java`s to all packges in `o.e.rest`. I
figure if the package is too small to deserve a `package-info.java` file
then it is too small to deserve to be a package....
Also fixes checkstyle in all moved classes.
The term persisted task was used to indicate that a task should store its results upon its completion. We would like to use this term to indicate that a task can survive restart of nodes instead. This commit removes usages of the term "persist" when it means store results.
As the most complicated `FetchSubPhase` highlighting gets its own package
(`o.e.seach.fetch.subphase.highlight`. No other `FetchSubPhase`s get their
own package. Instead they all reside together in `o.e.search.fetch.subphase`.
Add package descriptions to `o.e.search.fetch` and subpackages.
Previously, we only caught subclasses of Exception, however, there are
some cases when Errors are thrown instead of Exceptions. These two cases
are `assert` and when a class cannot be found.
Without this change, the exception would bubble up to the
`uncaughtExceptionHandler`, which would in turn, exit the JVM
(related: #19923).
A note of difference between regular Java asserts and Groovy asserts,
from http://docs.groovy-lang.org/docs/latest/html/documentation/core-testing-guide.html
"Another important difference from Java is that in Groovy assertions are
enabled by default. It has been a language design decision to remove the
possibility to deactivate assertions."
In the event that a user uses an assert such as:
```groovy
def bar=false; assert bar, "message";
```
The GroovyScriptEngineService throws a NoClassDefFoundError being unable
to find the `java.lang.StringBuffer` class. It is *highly* recommended
that any Groovy scripting user switch to using regular exceptions rather
than unconfiguration Groovy assertions.

Update by query is a shortcut to search + index. UpdateByQueryRequest gets serialized on the transport layer only when the transport client is used. Given that the request supports wildcards and allows to set its indices, it should implement IndicesRequest.Repleaceable. implementing CompositeIndicesRequest makes little sense as the indices that the request works against depend entirely on the inner search request.
Delete by query is a shortcut to search + delete. DeleteByQueryRequest gets serialized on the transport layer only when the transport client is used. Given that the request supports wildcards and allows to set its indices, it should implement IndicesRequest.Repleaceable
Fixes two issues:
1. lang-javascript doesn't support `executable` with a `null` `vars`
parameters. The parameter is quite nullable.
2. reindex didn't support script engines who's `unwrap` method wasn't
a noop. This didn't come up for lang-groovy or lang-painless because
both of those `unwrap`s were noops. lang-javascript copys all maps that
it `unwrap`s.
This adds fairly low level unit tests for these fixes but dosen't add
an integration test that makes sure that reindex and lang-javascript
play well together. That'd make backporting this difficult and would
add a fairly significant amount of time to the build for a fairly rare
interaction. Hopefully the unit tests will be enough.
I also reduced the visibility of a couple classes and renamed/consolidated some
test classes for consistency, eg. removing the `Simple` prefix or using the
`<Type>FieldMapperTests` convention for testing field mappers.

testUnknownObjectException used to generate malformed json objects in some cases, due to the existence of arrays as it was not closing the injected object correctly. That is why the test was catching JsonParseException among the exception that are expected to be thrown. That is fixed by tracking where the new object is placed and placing its end object marker to the right level rather than always at the end.
Also introduced a mechanism to explicitly declare objects that won't cause any exception when they get additional objects injected, so that there is no need to override the method anymore as that caused copy pasting of the whole test method. This also makes sure that changes are reflected in tests, as those inner objects are not skipped but we actually check that what is declared is true (no exceptions get thrown when an additional object is added within them.
When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following

This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

GeoDistance is implemented using a crazy enum that causes issues with the scripting modules. This commit moves all distance calculations to arcDistance and planeDistance static methods in GeoUtils. It also removes unnecessary distance helper methods from ScriptDocValues.GeoPoints.
Some random operations were conditionally performed in the before test, which made tests not repeatable. For instance take the seed chain to repeat a specific iteration and try to reproduce it, this conditional code would get executed in both cases when trying to isolate the failure, but not among the different iterations (as only the first method/iteration executes it), hence the failure will not reproduce.
Moved the random operations to beforeClass and left the non random part in the before method, which is needed as it depends on some method that can be overridden by subclasses.
Today when we load the Netty plugins, we indirectly cause several Netty
classes to initialize. This is because we attempt to load some classes
by name, and loading these classes is done in a way that triggers a long
chain of class initializers within Netty. We should not do this, this
can lead to log messages before the logger is loader, and it leads to
initialization in cases when the classes would never be needed (for
example, Netty 3 class initialization is never needed if Netty 4 is
used, and vice versa). This commit avoids this early initialization of
these classes by removing the need for the early loading.

Adds `warnings` syntax to the yaml test that allows you to expect

```

- quotes are not required because yaml

- no matter how many warnings you expect
get:

These are accessible from the docs with:
```

This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.
This commit increases the Netty 3 REST test suite timeout to thirty

splits the implementations so that regular histograms can support decimal
intervals/offsets and compute correct buckets for negative decimal values.
However the response API is still the same. So for intance both regular
histograms and date histograms will produce an
`org.elasticsearch.search.aggregations.bucket.histogram.Histogram`
aggregation.
The optimization to compute an identifier of the rounded value and the
rounded value itself has been removed since it was only used by regular
histograms, which now do the rounding themselves instead of relying on the
Rounding abstraction.

Currently any code that wants to added NamedWriteables to the
NamedWriteableRegistry can do so via guice injection of the registry,
and registering at construction time. However, this makes the registry
complex: it has both get and register methods synchronized, and there is
likely contention on the read side from multiple threads. The
registration has mostly already been contained to guice modules at node
construction time.
This change makes the registry immutable, taking all of the
NamedWriteable readers at construction time. It also allows plugins to
added arbitrary named writables that it may use in its own transport
actions.
This fixes a bug in the RunningStats class for the matrix stats aggregation module. doc counts were not being searlized which means they were only computed the first time the aggregation was computed. This was causing incorrect results when the aggregation was pulled from cache.
After #13834 many tests that used Groovy scripts (for good or bad reason) in their tests have been moved in the lang-groovy module and the issue #13837 has been created to track these messy tests in order to clean them up.
The work started with #19280, #19302 and #19336 and this PR moves the remaining messy tests back in core, removes the dependency on Groovy, changes the scripts in order to use the mocked script engine, and change the tests to integration tests.
It also moves IndexLookupIT test back (even if it has good chance to be removed soon) and fixes its tests.
It also changes AbstractQueryTestCase to use custom script plugins in tests.

In an effort to reduce the number of tiny packages we have in the

Also fixes line length in these packages.
`_reindex` only needs the `_version` if the `dest` has
`"version_type": "external"`. So it shouldn't ask for it unless it does.
`_update_by_query` and `_delete_by_query` always need the `_version`.
Closes#19135
This is cleanup work from #19566, where @nik9000 suggested trying to nuke the isCreated and isFound methods. I've combined nuking the two methods with removing UpdateHelper.Operation in favor of DocWriteResponse.Operation here.
Closes#19631.
Reindex from remote uses the Elasticsearch client which uses apache
httpasyncclient which spins up 5 thread by default, 1 as a dispatcher
and 4 more to handle IO. This changes Reindex's usage so it only spins
up two thread - 1 dispatcher and one to handle io. It also renames the
threads to "es-client-$taskid-$thread_number". That way if we see any
thread sticking around we can trace it back to the task.
The tests for authentication extend ESIntegTestCase and use a mock
authentication plugin. This way the clients don't have to worry about
running it. Sadly, that means we don't really have good coverage on the
REST portion of the authentication.
This also adds ElasticsearchStatusException, and exception on which you
can set an explicit status. The nice thing about it is that you can
set the RestStatus that it returns to whatever arbitrary status you like
based on the status that comes back from the remote system.
reindex-from-remote then uses it to wrap all remote failures, preserving
the status from the remote Elasticsearch or whatever proxy is between us
and the remove Elasticsearch.
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds an extra REST handler for "_ingest/pipeline" so that users do not need to supply "_ingest/pipeline/*" to get all of them.
- Also adds a teardown section to related REST-tests for ingest.
Performing the bulk request shown in #19267 now results in the following:
```
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"create","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":201}
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"noop","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":200}
```
Recently, we experience timeouts on our Windows build slaves for
Netty4RestIT. Until we have figured out what's going on, we
increase this test suite's timeout temporarily to ensure this
timeout does not mask other problems.
We disable transitive dependencies in our build plugin
for all dependencies except for the group `org.elasticsearch`.
However, in the reindex plugin we depend on the REST client
and declare its dependencies again which is not necessary
(and led to problems with conflicting versions in #19281).
With this PR we remove the duplicate declaration.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
Messy tests with mustache were either moved to core, moved to a rest test or remained untouched if they actually tested mustache.
Also removed tests that were redundant.
After #13834 many tests that used Groovy scripts (for good or bad reason) in their tests have been moved in the lang-groovy module and the issue #13837 has been created to track these messy tests in order to clean them up.

Fixes CORS handling so that it uses the defaults for http.cors.allow-methods

We better read the header, but who knows what can happen, maybe headers are filtered out for some reasons and we don't want to run into an NPE, then we fallback to auto-detection.
* rethrow script compilation exceptions into ingest configuration exceptions
* update readProcessor to rethrow any exception as an ElasticsearchException
Remove `ParseField` constants used for names where there are no deprecated
names and just use the `String` version of the registration method instead.
This is step 2 in cleaning up the plugin interface for extending
search time actions. Aggregations are next.
This is breaking for plugins because those that register a new query should
now implement `SearchPlugin` rather than `onModule(SearchModule)`.
* Remove outdated aggregation registration method
* Remove AggregationStreams
* Adds StreamInput#readNamedWriteableList and
StreamOutput#writeNamedWriteableList convenience methods. We strive to

The new method accepts the usual parameters (method, endpoint, params, entity and headers) plus a response listener and an async response consumer. Shortcut methods are also added that don't require params, entity and the async response consumer optional.
There are a few relevant api changes as a consequence of the move to async client that affect sync methods:
- Response doesn't implement Closeable anymore, responses don't need to be closed
- performRequest throws Exception rather than just IOException, as that is the the exception that we get from the FutureCallback#failed method in the async http client
- ssl configuration is a bit simpler, one only needs to call setSSLStrategy from a custom HttpClientConfigCallback, that doesn't end up overridng any other default around connection pooling (it used to happen with the sync client and make ssl configuration more complex)

The `client/transport` project adds a new jar build project that

Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
This changes adds a flag which can be set in the esplugin closure in
build.gradle for plugins and modules which contain pieces that must be
published to maven, for use in the transport client. The jar/pom and
source/javadoc jars are moved to a new name that has the suffix
"-client".
I enabled this for the two modules that I know definitely need this;
there may be more. One open question is which groupId to use for the
generated pom.
closes#19411
Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
Switches most search behavior extensions from push (`onModule(SearchModule)`)
to pull (`implements SearchPlugin`). This effort in general gives plugin
authors a much cleaner view of how to extend Elasticsearch and starts to
set up portions of Elasticsearch as "the plugin API". This commit in
particular does that for search-time behavior like customized suggesters,
highlighters, score functions, and significance heuristics.
It also switches most such customization to being done at search module
construction time which is much, much easier to reason about from a testing
perspective. It also helps significantly in the process of de-guice-ing
Elasticsearch's startup.
There are at least two major search time extensions that aren't covered in
this commit that will simply have to wait for the next commit on the topic
because this one has already grown large: custom aggregations and custom
queries. These will likely live in the same SearchPlugin interface as well.
If there are percolator queries containing `range` queries with ranges based on the current time then this can lead to incorrect results if the `percolate` query gets cached. These ranges are changing each time the `percolate` query gets executed and if this query gets cached then the results will be based on how the range was at the time when the `percolate` query got cached.
The ExtractQueryTermsService has been renamed `QueryAnalyzer` and now only deals with analyzing the query (extracting terms and deciding if the entire query is a verified match) . The `PercolatorFieldMapper` is responsible for adding the right fields based on the analysis the `QueryAnalyzer` has performed, because this is highly dependent on the field mappings. Also the `PercolatorFieldMapper` is responsible for creating the percolate query.
This exposes a method to start an action and return a task from
`NodeClient`. This allows reindex to use the injected `Client` rather
than require injecting `TransportAction`s

This adds a remote option to reindex that looks like
```
curl -POST 'localhost:9200/_reindex?pretty' -d'{
"source": {
"remote": {
"host": "http://otherhost:9200"
},
"index": "target",
"query": {
"match": {
"foo": "bar"
}
}
},
"dest": {
"index": "target"
}
}'
```
This reindex has all of the features of local reindex:
* Using queries to filter what is copied
* Retry on rejection
* Throttle/rethottle
The big advantage of this version is that it goes over the HTTP API
which can be made backwards compatible.
Some things are different:
The query field is sent directly to the other node rather than parsed
on the coordinating node. This should allow it to support constructs
that are invalid on the coordinating node but are valid on the target
node. Mostly, that means old syntax.
This commit renames writeThrowable to writeException. The situation here
stems from the fact that the StreamOutput method for serializing
Exceptions needs to accept Throwables too as Throwables can be the cause
of serialized Exceptions. Yet, we do not serialize Throwables in the
Error sub-hierarchy in a way that they can be deserialized into their
initial type. This leads to an asymmetry in the StreamOutput method for
serializing Exceptions and the StreamInput method for writing
Excpetions. Namely, the former will accept Throwables but the latter
will only return Exceptions. A goal with the stream methods has always
been symmetry in the method names so that serialization/deserialization
routines appear symmetrical in code. It is this asymmetry on the
input/output types for Exceptions on StreamOutput/StreamInput that
clashes with the desired symmetry of naming. Despite this, we should
favor symmetry in the naming of the methods. This commit renames
StreamOutput#writeThrowable to StreamOutput#writeException which leaves
us with Exception StreamInput#readException and void
StreamOutput#writeException(Throwable).
Today throughout the codebase, catch throwable is used with reckless
abandon. This is dangerous because the throwable could be a fatal
virtual machine error resulting from an internal error in the JVM, or an
out of memory error or a stack overflow error that leaves the virtual
machine in an unstable and unpredictable state. This commit removes
catch throwable from the codebase and removes the temptation to use it
by modifying listener APIs to receive instances of Exception instead of
the top-level Throwable.

BytesReference should be a really simple interface, yet it has a gazillion
ways to achieve the same this. Methods like `#hasArray`, `#toBytesArray`, `#copyBytesArray`
`#toBytesRef` `#bytes` are all really duplicates. This change simplifies the interface
dramatically and makes implementations of it much simpler. All array access has been removed
and is streamlined through a single `#toBytesRef` method. Utility methods to materialize a
compact byte array has been added too for convenience.
We'll migrate to NamedWriteable so we can share code with the rest
of the system. So we can work on this in multiple pull requests without
breaking Elasticsearch in between the commits this change supports
*both* old style `InternalAggregations.stream` serialization and
`NamedWriteable` style serialization. As such it creates about a
half dozen `// NORELEASE` comments that will have to be removed
once the migration is complete.
This also introduces a boolean `transportClient` flag to `SearchModule`
which is used to skip inappropriate registrations for for the
transport client while still registering the things it needs. In
this case that means that the `InternalAggregation` subclasses are
registered with the `NamedWriteableRegistry` but the `AggregationBuilder`
subclasses are not.
Finally, this moves aggregation registration from guice configuration
time to `SearchModule` construction time. This will make it simpler to
work with in the future as we further clean up Elasticsearch's
extension points.
We have long worked to capture different partitioning scenarios in our testing infra. This PR adds a new variant, inspired by the Jepsen blogs, which was forgotten far - namely a partition where one node can still see and be seen by all other nodes. It also updates the resiliency page to better reflect all the work that was done in this area.
Update-By-Query and Delete-By-Query use internal versioning to update/delete documents. But documents can have a version number equal to zero using the external versioning... making the UBQ/DBQ request fail because zero is not a valid version number and they only support internal versioning for now. Sequence numbers might help to solve this issue in the future.
The factory for ingest processor is generic, but that is only for the
return type of the create mehtod. However, the actual consumer of the
factories only cares about Processor, so generics are not needed.
This change removes the generic type from the factory. It also removes
AbstractProcessorFactory which only existed in order pull the optional
tag from config. This functionality is moved to the caller of the
factories in ConfigurationUtil, and the create method now takes the tag.
This allows the covariant return of the implementation to work with
tests not needing casts.
Previously all rest handlers would take Client in their injected ctor.
However, it was only to hold the client around for runtime. Instead,
this can be done just once in the HttpService which handles rest
requests, and passed along through the handleRequest method. It also
should always be a NodeClient, and other types of Clients (eg a
TransportClient) would not work anyways (and some handlers can be
simplified in follow ups like reindex by taking NodeClient).
`RestHandler`s are highly tied to actions so registering them in the
same place makes sense.
Removes the need to for plugins to check if they are in transport client
mode before registering a RestHandler - `getRestHandlers` isn't called
at all in transport client mode.
This caused guice to throw a massive fit about the circular dependency
between NodeClient and the allocation deciders. I broke the circular
dependency by registering the actions map with the node client after
instantiation.
This pull request adds two util functions to the Mustache templating engine:
- {{#toJson}}my_map{{/toJson}} to render a Map parameter as a JSON string
- {{#join}}my_iterable{{/join}} to render any iterable (including arrays) as a comma separated list of values like `1, 2, 3`. It's also possible de change the default delimiter (comma) to something else.

Stored scripts are pulled from the cluster state, and the current api
requires passing the ClusterState on each call to compile. However, this
means every user of the ScriptService needs to depend on the
ClusterService. Instead, this change makes the ScriptService a
ClusterStateListener. It also simplifies tests a lot, as they no longer
need to create fake cluster states (except when testing stored scripts).
Instead of implementing onModule(ActionModule) to register actions,
this has plugins implement ActionPlugin to declare actions. This is
yet another step in cleaning up the plugin infrastructure.
While I was in there I switched AutoCreateIndex and DestructiveOperations
to be eagerly constructed which makes them easier to use when
de-guice-ing the code base.
Previous to this change the unresolved extended bounds was passed into the histogram aggregator which meant extendedbounds.min and extendedbounds.max was passed through as null. This had two effects on the histogram aggregator:
1. If the histogram aggregator was unmapped across all shards, the reduce phase would not add buckets for the extended bounds and the response would contain zero buckets
2. If the histogram aggregator was not unmapped in some shards, the reduce phase might sometimes chose to reduce based on the unmapped shard response and therefore the extended bounds would be ignored.
This change resolves the extended bounds in the unmapped case and solves the above two issues.
Closes#19009
This commit fixes several NPEs caused by implicitly performing a get request for a document that exists with its _source disabled and then trying to access the source. Instead of causing an NPE the following queries will throw an exception with a "source disabled" message (similar behavior as if the document does not exist).:
- GeoShape query for pre-indexed shape (throws IllegalArgumentException)
- Percolate query for an existing document (throws IllegalArgumentException)
A Terms query with a lookup will ignore the document if the source does not exist (same as if the document does not exist).
GET and HEAD requests for the document _source will return a 404 if the source is disabled (even if the document exists).
Instead of plugins calling `registerTokenizer` to extend the analyzer
they now instead have to implement `AnalysisPlugin` and override
`getTokenizer`. This lines up extending plugins in with extending
scripts. This allows `AnalysisModule` to construct the `AnalysisRegistry`
immediately as part of its constructor which makes testing anslysis
much simpler.
This also moves the default analysis configuration into `AnalysisModule`
which is how search is setup.
Like `ScriptModule`, `AnalysisModule` no longer extends `AbstractModule`.
Instead it is only responsible for building `AnslysisRegistry`. We still
bind `AnalysisRegistry` but we only do so in `Node`. This is means it
is available at module construction time so we slowly remove the need to
bind it in guice.

If we don't care about scoring then for certain candidate matches we can be certain, that if they are a candidate match,
then they will always match. So verifying these queries with the MemoryIndex can be skipped.

This commit moves template support out of the Search API to its own dedicated Search Template API in the lang-mustache module. It provides a new SearchTemplateAction that can be used to render templates before it gets delegated to the usual Search API. The current REST endpoint are identical, but the Render Search Template endpoint now uses the same Search Template API with a new "simulate" option. When this option is enabled, the Search Template API only renders template and returns immediatly, without executing the search.

This changes adds a MapperPlugin interface which allows pull style
retrieval of mappers and metadata mappers added by plugins. For now, I
have kept the MapperRegistry, but this should be removed in the future

Makes ScriptModule just a plain class that manages building the
ScriptSettings and ScriptService from plugins. When we *need*
to bind ScriptService with guice we bind it in a lambda.
- fix it so that processors with the `ignore_failure` option do not
record their exception in the response
- add more tests to make empty `on_failure`. This now throws an
exception
This makes this sequence:

curl -XPOST localhost:9200/source/test -d'{"test": "test"}'; echo

curl 'localhost:9200/_tasks/Jsyd6d9wSRW-O-NiiKbPcQ:237?wait_for_completion&pretty'
```
Return task *AND* the response to the user.
This also renames "result" to "response" in the persisted task info
to line it up with how we name the objects in Elasticsearch.
Perviously we used token level lookbehind in the parser. That worked,
but only if the parser didn't have any ambiguity *at all*. Since the
parser has ambiguity it didn't work everywhere. In particular it failed
when parsing blocks in lambdas like `a -> {int b = a + 2; b * b}`.
This moves the hack from the parser into the lexer. There we can use
token lookbehind (same trick) to *insert* semicolons into the token
stream. This works much better for antlr because antlr's prediction
code can work with real tokens.
Also, the lexer is simpler than the parser, so if there is a place
to introduce a hack, that is a better place.
This change removes some unnecessary dependencies from ClusterService
and cleans up ClusterName creation. ClusterService is now not created
by guice anymore.

Today we have a push model for registering basically anything. All our extension points
are defined on modules which we pass in to plugins. This is harder to maintain and adds
unnecessary dependencies on the modules itself. This change moves towards a pull model
where the plugin offers a getter kind of method to get the extensions. This will also
help in the future if we need to pass dependencies to the extension points which can
easily be defined on the method as arguments if a pull model is used.
Adds support for the find operator (=~) and the match operator (==~)
to painless's regexes. Also whitelists most of the Matcher class and
documents regex support in painless.
The find operator (=~) returns a boolean that is the result of building
a matcher on the lhs with the Pattern on the RHS and calling `find` on
it. Use it like this:
```
if (ctx._source.last =~ /b/)
```
The match operator (==~) returns boolean like find but instead of calling
`find` on the Matcher it calls `matches`.
```
if (ctx._source.last ==~ /[^aeiou].*[aeiou]/)
```
Finally, if you want the actual matcher you do:
```
Matcher m = /[aeiou]/.matcher(ctx._source.last)
```
Registering a script engine or native scripts still uses Guice today
and is much more complicated than needed. This change moves to a pull
based model where script plugins have to implement a dedicated interface
`ScriptPlugin` and defines simple getter returning instances rather than
classes.
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.
This interface used to have dedicated methods to prevent calling execute
methods. These methods are unnecessary as the checks can simply be
done inside the execute methods itself. This simplifies the interface
as well as its usage.
This adds a get task API that supports GET /_tasks/${taskId} and
removes that responsibility from the list tasks API. The get task
API supports wait_for_complation just as the list tasks API does
but doesn't support any of the list task API's filters. In exchange,
it supports falling back to the .results index when the task isn't
running any more. Like any good GET API it 404s when it doesn't
find the task.
Then we change reindex, update-by-query, and delete-by-query to
persist the task result when wait_for_completion=false. The leads
to the neat behavior that, once you start a reindex with
wait_for_completion=false, you can fetch the result of the task by
using the get task API and see the result when it has finished.
Also rename the .results index to .tasks.
Adds `/regex/` as a regex constructor. A couple of fun points:
1. This makes generic the idea of arbitrary stuff adding a constant.
Both SFunction and LRegex create a statically initialized constant.
Both go through Locals to do this because they LRegex isn't directly
iterable from SScript.
2. Differentiating `/` as-in-division from `/` as-in-start-of-regex
is hard. See:
http://www-archive.mozilla.org/js/language/js20-2002-04/rationale/syntax.html#regular-expressions
The javascript folks have a way, way tougher time of it then we do
because they have semicolon insertion. We have the much simpler
delimiter rules. Even with our simpler life we still have to add
a hack to get lexing `/regex/` to work properly. I chose to add
token-level lookbehind because it seems to be a pretty contained hack.
I considered and rejected lexer modes, a lexer member variable,
having the parser set variables on the lexer (this is a fairly common
solution for js, I believe), and moving regex parsing to the parser
level.
3. I've only added a very small subset of java.util.regex to the
whitelist because it is the subset I needed to test LRegex sanely.
More deserves to be added, and maybe more regex syntax like `=~` and
`==~`. Those can probably be added without too much pain.
Add `}` is statement delimiter but only in places where it is
otherwise a valid part of the syntax, specificall the end of a block.
We do this by matching but not consuming it. Antlr 4 doesn't have
syntax for this so we have to kind of hack it together by actually
matching the `}` and then seeking backwards in the token stream to
"unmatch" it. This looks reasonably efficient. Not perfect, but way
better than the alternatives.
I tried and rejected a few options:
1. Actually consuming the `}` and piping a boolean all through the
grammar from the last statement in a block to the delimiter. This
ended up being a rather large change and made the grammar way more
complicated.
2. Adding a semantic predicate to delimiter that just does the
lookahead. This doesn't work out well because it doesn't work (I
never figured out why) and because it generates an *amazing*
`adaptivePredict` which makes a super huge DFA. It looks super
inefficient.
Closes#18821
Writeable is better for immutable objects like TimeValue.
Switch to writeZLong which takes up less space than the original
writeLong in the majority of cases. Since we expect negative
TimeValues we shouldn't use
writeVLong.
Today we use a random source of UUIDs for assigning allocation IDs,
cluster IDs, etc. Yet, the source of randomness for this is not
reproducible in tests. Since allocation IDs end up as keys in hash maps,
this means allocation decisions and not reproducible in tests and this
leads to non-reproducible test failures. This commit modifies the
behavior of random UUIDs so that they are reproducible under tests. The
behavior for production code is not changed, we still use a true source
of secure randomness but under tests we just use a reproducible source
of non-secure randomness.
It is important to note that there is a test,
UUIDTests#testThreadedRandomUUID that relies on the UUIDs being truly
random. Thus, we have to modify the setup for this test to use a true
source of randomness. Thus, this is one test that will never be
reproducible but it is intentionally so.

The painless whitelist has a lot of self-checking, in this case, it checks
for missing covariant overrides. It fails on java 9, because LocalDate.getEra()
now returns IsoEra instead of Era: https://bugs.openjdk.java.net/browse/JDK-8072746
To our checker, it thinks we were lazy with whitelisting :)
This means painless works on java 9 again

The rest tests have been moved to ingest-common module as well, because these tests don't run in the rest-api-spec module but in the distribution:integ-test-zip module

This commit refactors the handling of thread pool settings so that the
individual settings can be registered rather than registering the top
level group. With this refactoring, individual plugins must now register
their own settings for custom thread pools that they need, but a
dedicated API is provided for this in the thread pool module. This
commit also renames the prefix on the thread pool settings from
"threadpool" to "thread_pool". This enables a hard break on the settings
so that:
- some of the settings can be given more sensible names (e.g., the max
number of threads in a scaling thread pool is now named "max" instead
of "size")
- change the soft limit on the number of threads in the bulk and
indexing thread pools to a hard limit
- the settings names for custom plugins for thread pools can be
prefixed (e.g., "xpack.watcher.thread_pool.size")
- remove dynamic thread pool settings
Relates #18674
This adds support for setting the refresh request parameter to
`wait_for` in the `index`, `delete`, `update`, and `bulk` APIs. When
`refresh=wait_for` is set those APIs will not return until their
results have been made visible to search by a refresh.
Also it adds a `forced_refresh` field to the response of `index`,
`delete`, `update`, and to each item in a bulk response. This will
be true for requests with `?refresh` or `?refresh=true` and will be
true for some requests (see below) with `refresh=wait_for` but ought
to otherwise always be false.
`refresh=wait_for` is implemented as a list of
`Tuple<Translog.Location, Consumer<Boolean>>`s in the new `RefreshListeners`
class that is managed by `IndexShard`. The dynamic, index scoped
`index.max_refresh_listeners` setting controls a maximum number of
listeners allowed in any shard. If more than that many listeners
accumulate in the engine then a refresh will be forced, the thread that
adds the listener will be blocked until the refresh completes, and then the
listener will be called with a `forcedRefresh` flag so it knows that it was
the "straw that broke the camel's back". These listeners are only used by
`refresh=wait_for` and that flag manifests itself as `forced_refresh` being
`true` in the response.
About half of this change comes from piping async-ness down to the appropriate
layer in a way that is compatible with the ongoing with with sequence ids.

Handle hanging documents
If a document is added to the index during a refresh we weren't properly
firing its refresh listener. This happened because the way we detect
whether a refresh makes something visible or not is imperfect. It is
ok because it always errs on the side of thinking that something isn't
yet visible.
So when a document arrives during a refresh the refresh listeners
won't think it made it into a refresh when, often, it does. The way
we work around this is by telling Elasticsearch that it ought to
trigger a refresh if there are any pending refresh listeners even
if there aren't pending documents to update. Lucene short circuits
the refresh so it doesn't take that much effort, but the refresh
listeners still get the signal that a refresh has come in and they
still pick up the change and notify the listener.
This means that the time that a listener can wait is actually slightly
longer than the refresh interval.

Remove Translog#lastWriteLocation
I wasn't being careful enough with locks so it wasn't right anyway.
Instead this builds a synthetic Tranlog.Location when you call
getWriteLocation with much more relaxed equality guarantees. Rather
than being equal to the last Translog.Location returned it is
simply guaranteed to be greater than the last translog returned
and less than the next.

Move refresh listeners into their own class
They still live at the IndexShard level but they live on their
own in RefreshListeners which interacts with IndexShard using a
couple of callbacks and a registration method. This lets us test
the listeners without standing up an entire IndexShard. We still
test the listeners against an InternalEngine, because the interplay
between InternalEngine, Translog, and RefreshListeners is complex
and important to get right.

Switch to estimated count
We don't need a linear time count of the number of listeners - a volatile
variable is good enough to guess. It probably undercounts more than it
overcounts but it isn't a huge problem.

Never reply to replica actions while you have the operation lock
This last thing was causing periodic test failures because we were
replying while we had the operation lock. Now, we probably could get
away with that in most cases but the tests don't like it and it isn't
a good idea to do network io while you have a lock anyway. So this
prevents it.

Create ReplicatedMutationRequest
Superclass for index, delete, and bulkShard requests.

Create TransportReplicatedMutationAction
It is the superclass of replication actions that mutate data: index, delete,
and shardBulk. shardFlush and shardRefresh are replication actions but they
do not extend TransportReplicatedMutationAction because they don't change
the data, only shuffle it around.

Currently we support empty query clauses like the filter in
"constant_score" : { "filter" : { } }
How these clauses are handled depends on the surrounding query.
They later are either ignored, converted to match all or no documents or
passed up further in the query hierarchy. During parsing these claues are
currently represented as EmptyQueryBuilders. When not handled anywhere else,
these special cases need to be checked for on the shard when building the
lucene query.
This is trappy, so this PR changes the parsing of compound queries. Instead
of returning QueryBuilder, the core query parsing method
QueryShardContext#parseInnerQueryBuilder() now return an Optional which can
be empty in the case of empty query clauses. This has the advantage of forcing
callers to deal with this sooner or later. When encountering empty Optionals,
compound query builders now have the choice to ignore them, pass them on or
rewrite to a different query, depending on context.
This commit adds a new aggs-matrix-stats module. The module presents a new class of aggregations called Matrix Aggregations. Matrix aggregations work on multiple fields and produce a matrix as output. The first matrix aggregation provided by the module is matrix_stats aggregation. This aggregation computes the following statistics over a set of fields:
* Covariance
* Correlation
For completeness (and interpretation purposes) the following per-field statistics are also provided:
* sample count
* population mean
* population variance
* population skewness
* population kurtosis
Similar reasoning as #18133 but for the aggs API. One important change is that
I moved the base PipelineAggregatorBuilder class to the o.e.s.aggregations
package instead of o.e.s.aggregations.pipeline so that the create method does
not need to be public.
There is no reason to read the entire marvel hero file to test the features,
it might take several seconds to do so which is unnecessary.
This commit also splits SearchSuggestTests into core and modules/mustache
also add @Nighlty to forbidden API to make sure we don't use it since they won't run in CI these days.
- now you can specify a list of grok patterns to match your field with
and the first one to successfully match wins.
- only non-null captures will be inserted into your matched document.
Fixes#17903.
