We try to get the index shard instance again from the index service on a different
threads while that shard might have already been closed or removed which can cause a NPE
instead of another expected expecption.
This commit shuffels and rewrites some code in RecoverySourceHandler to make it
simpler and more unittestable. This commit doesn't change all parts of this class
neither is it fully tested yet. It's an important part of the infrastrucutre so I started
to make it better tested but I don't want to change everything in one go since it makes
review simpler and more detailed. Future commits will continue cleaning up the class and
add more tests.
If a document is indexed into ES with no id, ES will generate one for it. We used to have an optimization for this case where the engine will not try to resolve the ids of these request in the existing index but immediately try to index them. This optimization has proven to be the source of brittle bugs (solved!) and we disabled it in 1.5, preparing for it to be removed if no performance degradation was found. Since we haven't seen any such degradation we can remove it.
Along with the removal of the optmization, we can remove the autogenerate id flag on indexing requests and the can have duplicate flag. The only downside of the removal of the canHaveDuplicate flag is that we can't make sure any more that when we retry an autogenerated id create operation we will ignore any document already exists exception (See #9125 for background and discussion). To work around this, we don't set the operation to CREATE any more when we generate an id, so the resulting request will never fail when it finds an existing doc but do return a version of 2. I think that's acceptable.
Closes#13857
We have two unneded heavy dependencies on IndexShard that are unneeded and only cause
trouble if you try to mock index shard. This commit removes IndexSettingsService as well as
ClusterSerivce from IndexShard to simplify future mocking and construction.
While refactoring has_child and has_parent query we lost an important detail around types. The types that the inner query gets executed against shouldn't be the main types of the search request but the parent or child type set to the parent query. We used to use QueryParseContext#setTypesWithPrevious as part of XContentStructure class which has been deleted, without taking care though of setting the types and restoring them as part of the innerQuery#toQuery call.
Meanwhile also we make sure that the original context types are restored in PercolatorQueriesRegistry

Add SpecialPermission to guard exceptions to security policy.
In some cases (e.g. buggy cloud libraries, scripting engines), we must
grant dangerous permissions to contained cases. Those AccessController blocks
are dangerous, since they truncate the stack, and can allow privilege escalation.
This PR adds a simple permission to check before each one, so that unprivileged code
like groovy scripts, can't do anything they shouldn't be allowed to do otherwise.
StoreRecoveryService used to be a pretty heavy class with lots of dependencies.
This class was basically not testable in isolation and had an async API with a listener.
This commit refactors this class to be a simple utility classs with a sync API hidden behind
the IndexShard interface. It includes single node tests and moves all the async properities to
the caller side.
Note, this change also removes the mapping update on master from the store recovery code since
it's not needed anymore in 3.0 because all stores have been subject to sync mapping updates such
that the master already has all the mappings for documents that made it into the transaction log.
Closes#13766
Now that groovy is factored out, we contain this dangerous stuff there.
TODO: look into those test hacks inspecting class protection domains, maybe we can
clean that one up too.
TODO: generalize the GroovyCodeSourcePermission to something all script engines check,
before entering accesscontrollerblocks. this way e.g. groovy script cannot coerce
python engine into creating something with more privs if it gets ahold of it... we
should probably protect the aws/gce hacks in the same way.
Previous to this change if to equal geohash cell query builders were created and then toQuery was called on one, they would no longer be equal.
This change also adds a test to AbstractQueryTestCase to make sure calling toQuery on any query builder does not affect the query builder's equality
* Add OS X support via "seatbelt" mechanism. This gives consistency across dev and prod, since many devs use OS X.
* block execveat system call: it may be new, but we should not allow it.
When a shard becomes in active we trigger a sync flush in order to speed up future recoveries. The sync flush causes a new translog generation to be made, which in turn confuses the IndexingMemoryController making it think that the shard is active. If no documents comes along in the next 5m, the shard is made inactive again , triggering a sync flush and so forth.
To avoid this, the IndexingMemoryController is changed to ignore empty translogs when checking if a shard became active. This comes with the price of potentially missing indexing operations which are followed by a flush. This is acceptable as if no more index operation come in, it's OK to leave the shard in active.
A new unit test is introduced and comparable integration tests are removed.
Closes#13802
Instead just log the same thing we print to the startup console for that case (magic logic),
it sucks to do this, but guice exceptions are too much.
All other non-guice exceptions will still be fully logged.
Closes#13782
This commit adds explicit ids for managing ElasticsearchException
serialization. By adding explicit ids and unit tests for them, the ids
are less brittle and breakage can be more clearly detected.
Today we use reflection where it's not needed anymore since java8 can
pass ctors around. This commit replaces runtime checks with compile time
checks which is always preferrable.
These classes are really duplicates and are just here for historical reasons.
We don't need these anymore since the same classes exist in lucene today.
This also removes the guice injection for DeletionPolicy and make them shard private.
TermsLookupQueryBuilder was left around only for bw comp reasons, but TermsQueryBuilder is its replacement. We can remove it now that it is clear query refactoring goes in master (3.0).
There is no need to have term vectors service on the shard level where it's
created for every shard. This commit moves it to a higher level which makes
shard creation slightly simpler and reduces the number of long living objects.
Before the refactoring we didn't check any invalid settings for strategy and relation
in the GeoShapeQueryBuilder. However, using SpatialStrategy.TERM and ShapeRelation.INTERSECTS
together is invalid and we tried to protect against that in the validate() method.
This PR moves these checks to setter for strategy and relation and adds tests for the new
behaviour.

Some methods had default implementation while queries were going to be refactored, now that they are all refactored all those methods can be made abstract.
Remove ParseFieldMatcher duplication query in both contexts. QueryParseContext is still contained in QueryShardContext, as parsing still happens in the shards here and there. Most of the norelease comments have been removed simply because the scope of the refactoring has become smaller. Some could only be removed once everything, the whole search request, gets parsed on the coordinating node. We will get there eventually.
SimpleIndexQueryParserTests was the main responsible: deleted lots of duplicated tests, moved the ones that made sense to keep to their corresponding unit tests (note they were ESSingleNode tests before while are now converted to unit tests).
Closes#13750
After all queries now have a `toQuery` method and the parsers all
support `fromXContent` it is possible to remove the following
workarounds and deprecated methods we kept around while doing the
refactoring:
* remove the BaseQueryParser and BaseQueryParserTemp. All parsers
implement QueryParser directly now
* remove deprecated methods in QueryParseContext that either returned
a Query or a Filter.
* remove the temporary QueryWrapperQueryBuilder

The IndexingMemoryController checks periodically if there is any indexing activity on the shard. If no activity is sean for 5m (default) the shard is marked as inactive allowing it's indexing buffer quota to given to other active shards.
Sadly the current check is bad as it checks for 0 translog operation. This makes the inactive wait for a flush to happen - which used to take 30m and since #13707 doesn't happen at all (as we rely on the synced flush triggered by inactivity). This commit fixes the check so it will work with any translog size.
Closes#13759
This commit fixes ping timeout settings inconsistencies in

The current MoreLikeThisQueryBuilder validation checks for existence of at
least one `like` text or item. This is hard to check in setters, so this PR
tries to change the construction of the query so that we can do these checks
already at construction time.

and unlikeItems. `likeTexts` and/or `likeItems` need to be specified at
construction time to validate we have at least one item there.

Banning `ImmutableSet` outright is too much to do all at once - this starts
the process by banning `ImmutableMap#entrySet` - one of the more common ways
that `ImmutableSet`s come up. It then starts to remove calls to
`ImmutableMap#entrySet` by changing declarations from `ImmutableMap` to `Map`.
Unfortunately this process is like pulling on a long, windy string and one
declaration change requires another which requires 5 more which in turn
require another few. So this change is rather large.
As such, to keep the changes manageable they only remove `ImmutableMap` from
the signatures that are needed for `entrySet` and make little effort to stop
using `ImmutableMap` internally. Removing the usages of `ImmutableMap`
complicates immutability guarantees and will be done separately.
In #12942, the NettyTransport and NettyHttpServerTransport were updated to allow for binding
to multiple addresses. However, the BoundTransportAddress holder only exposed the first address
that the transport was bound to and this object is used to populate the values returned to the user
via our APIs.
This change exposes all of the bound addresses in the BoundTransportAddress holder, which allows
for an accurate representation of all interfaces that elasticsearch is bound to and listening on.
Not the neatest implementation in the world. Maybe we should consider changing the builders so it is a single builder for sort and a single builder for rescore instead of a list of builders for each?
This commit addresses a confusing error message that arises when a
property parameter (e.g. -D) is after a double-dash parameter. The
current error message reports to the user that the parameter does not
start with “--". Adding the second dash as the error message suggests
causes the parameter to be silently ignored. This is confusing for the
user. With this commit, the user is now informed that the parameter
order is violated.

These exceptions are useless and unused, since we are on a major verison we should remove
them. This commit also makes it easier to remove excepitons in the future.
In the past ClusterStateUpdateTask was an interface and we had various derived marker interfaces to control behavior. Since then we moved ClusterStateUpdateTask to be an abstract class but we kept the old hierarchy of implementations. All of those (but the AckedClusterStateUpdateTask) can be folded into ClusterStateUpdateTask, adding correct default behavior.

This commit moves the size and ops based flush into a synchronous API into
IndexShard and removes the time-based flush alltogether since it' basically
covered by the inactive async flush API we have today. The functionality doesn't

the decisions in a sync manner which is way easier to control and to test.

This commit removes all the opaque bytes for extra_source and template_source.
Instead source and extra_source etc. are represented as SearchSourceBuilder which can

Template Source is parsed and evaluated which in-turn replaces the actual source.
Refactor the function_score query so it can be parsed on the coordinating node, split parse into fromXContent and toQuery, make FunctionScoreQueryBuilder Writeable.
Closes#13653
Given that we are moving to parsing queries on the coordinating node, the index name is not relevant anymore in QueryParseContext, as the parsing phase cannot be related to any specific index. On the contrary, the QueryShardContext is the one that holds mappings etc. and the index name too, as the lucene query creation happens on the data node and can still be related with the index that it happens against.
Changes are mainly around tests that were expecting the index name, moved to using QueryShardException in some of them, removed the index name elsewhere.

This parser prototype allows to decleratively define parsers for XContent
instead of writing messy and error prone while loops. It encapsulates all the error handling logic
and only even tries to parse if the token types match the declaration.
I want to refactor scripting engines so we can contain dangerous "God-like" permissions
like createClassloader/sun.reflect. These are used for dynamic class generation (scripts, mocks).
This will mean some refactoring to ES core.
But first lets get the plugins in order first. I removed those permissions globally, and
fixed grants for lang-javascript, lang-python, securemock so that everything works.
lang-javascript needs no code changes, because rhino is properly written :)
lang-python needs accesscontroller blocks. securemock was already working as of 1.1
This is just a baby step, to try to do some of this incrementally! It doesn't yet provide
us anything.
Currently the tribe node version always stays 0, which can cause issues for the services that rely on cluster state version. For example, ClusterStateObserver doesn't revalidate the cluster state after change, which leads to cluster health check with wait flags to take much longer then actually needed.
Until now we had a cloud-azure plugin which is providing 3 distinct features:
* discovery on Azure
* snapshot/restore on Aure
* SMB store
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
This add equals, hashcode, read/write methods, validation, separates toQuery
and JSON parsing and adds serialization and query generation tests.
Deprecates two types of initializing the bounding box: In our documentation we
speak about specifying top/left and bottom/right corner of a bounding box. Here
we also allow for top/right and bottom/left. This adds not only to the amount
of code but also testing needed w/o too much benefit for the user other than
more chances to confuse top/right/bottom/left/latitude/longitude IMHO.
Missing: The toQuery method with type set to "indexed" is not tested at the
moment.
Cleanup changes unrelated to base refactoring:
* Switched from type String to enum for types in GeoBoundingBoxQueryBuilder.
* Switched to using type GeoPoint for storing the bounding box coordinates
instead of array of double values.

1 hour total adding the real functionality, days of wasted time
on simulated fake functionality to satisfy our crazy test framework...
I debugged on the problematic jenkins machine and I think issues are
from parsing the classpath and URL normalization etc (trailing slashes
vs not, etc in URLs). So I simplifed the code, to remove this completely,
inverting the logic so we just use an exclusion list instead of inclusion one.
I also allow tests for these plugins to run from the IDE (works at least for eclipse) too.
At least for eclipse this is even less realistic as it piles all the code (src and test)
into a single codebase, but it means you can *use it* and you just have to run mvn verify
before pushing as always. And as always... best effort.
A JTS bug causes a misinterpretation of polygon coordinates leading to an unhelpful "geom" AssertionError. While this assertion occurs approx 0.02% of the time it can lead to a misleading test failure. This patch catches the geom assertion and retries randomShapeCreation. For safety a threshold is set to prevent unlimited retrying - though 1 retry is typically sufficient for correcting the invalid shape.

We don't have a plugin .zip for unit tests, so we can't do it

Classnames change quickly due to refactorings etc. If that happens in a minor release
we loose the ability to deserialize the exceptoin coming from another node sicne we today

Especially the worst of the worst with thread permissions: for example,
this prevents some code from starting daemon thread that will outlive
the elasticsearch process and hang around doing evil shit.

unfixable since it has to serialize XContent and read from it which can't

Weighted centroid, morton hash, and geohash can be imprecise (computation error) to 1e-5. The previous compareTo set this tolerance too strict (1e-6) causing a reproducible comparison error on weighted centroid (#13558). This change relaxes the tolerance to the acceptable computation error of 1e-5

If we don't wait we might retrieve the cluster state before second node
was added when we try to add the delegate in which the discovery node for
node_2 is null.
When a single node starts up it will first elect itself as master and then tries to
recover the cluster state or, if there is none, initialize an empty one and publish it.
Until it has done that, the cluster state will contain a global block and
requests might fail with
SERVICE_UNAVAILABLE/1/state not recovered / initialized
We need to wait for green.
This commit fixes a test bug in
o.e.a.s.b.n.TransportBroadcastByNodeActionTests. Namely, the randomized
test allowed for the creation of cluster states that allocated indices
having zero shards. This ultimately surfaced in a

shards. The fix is merely to draw the random number of shards from 1 to

When publishing a new cluster state, the master will send it to all the node of the cluster, noting down how many *master* nodes responded successfully. The nodes do not yet process the new cluster state, but rather park it in memory. As soon as at least minimum master nodes have ack-ed the cluster state change, it is committed and a commit request is sent to all the node that responded so far (and will respond in the future). Once receiving the commit requests the nodes continue to process the cluster state change as they did before this change.
A few notable comments:
1. For this change to have effect, min master nodes must be configured.
2. All basic cluster state validation is done in the first phase of publish and is thus now part of `ShardOperationResult`
3. A new `COMMIT_TIMEOUT` settings is introduced, dictating how long a master should wait for nodes to ack the first phase. Unlike `PUBLISH_TIMEOUT`, if waiting for a commit times out, the cluster state change will be rejected.
4. Failing to achieve a min master node of acks, will cause the master to step down as it clearly doesn't have enough active followers.
5. Previously there was a short window between the moment a master lost it's followers and it stepping down because of node fault detection failures. In this short window, the master could process any change (but fail to publish it). This PR closes this gap to 0.
6. A dedicated pending cluster states queue was added to keep pending non-comitted cluster states and manage the logic around processing committed cluster states. See #13303 for details.

This commit allows to refresh the info service in a blocking fashion
which allows tests to prevent installing listeners alltogether and
makes the class easier to test. Installing a listnener is always subject
to concurrent modifications where the listener might be called mulitple times
or with stale information which causes tests to fail.
Java 8 allows for method references which in-turn will cause
compile errors if a method is not visible while reflection fails late
and maybe too late. We can now register Request instances via FooRequest::new
instead of passing FooRequest.class and call it's ctor via reflection.
This test sometimes fails because the first node is elected as master and waits 30s for incoming joins but in the meanwhile the 3 other nodes form a cluster on their side. The index will be created and its shards allocated on these 3 nodes, then the test checks for the number of shards on each node (it should be 2 or 3) but because the first node has not fully join the cluster yet one node will have 5 shards.

1. FileSystem wrapping code is broken, thats why you get providermismatch exception!
Instead of fixing this, it SuppressesForbidden!!!!
2. Because it uses SuppressForbidden on the test, the whole thing is lenient, it uses java.io.File for example!
3. Of course it fails consistently on windows because it can't remove files, because it leaks file handles (locks)
like a sieve since it does not close node environment. With correct wrapping this is always detected by e.g.
our leak detection FS. Instead of fixing the leak, it assumesFalse(WINDOWS) !!!!!

During the second phase of recovery, replayed transaction log entries may need to wait on mapping changes that have not yet propagated to the target node. Currently we correctly replay the operation at a later stage, but we acknowledge the replay request before actually performing the work.

If the machine is very slow this test fails if the delta of the unallocaiton
timestamp and the last scheduled delay is greater than the scheduled delay time.
Today this is really horrible, and we have a PR sent to fix it, but nobody

With java 9, we cannot even grant the permission, this kind of sheistiness is not allowed,
and s3 repository is completely broken.
The problem is their code is still broken, and won't handle neither SecurityException (our PR)
nor the new InaccessibleObjectException they will get from java 9.
We use a really hacky hack to deliver an exception that their code catches (IllegalAccessException) instead.
This means s3 repository is working on java 9, and we close off access to sun.security.ssl completely
Don't worry, I will fix the rest. But some of those remaining will need a lucene upgrade,
we need to add a getter or two for tests to do things cleanly.
In addition to being a big security problem, setAccessible is a risk
for java 9 migration. We need to clean up our code so we can ban it
and eventually enforce this with security manager for third-party code, too,
or we may have problems.
Instead of using setAccessible, use the correct modifier (e.g. public).

The initial implementation of two phase commit based cluster state publishing (#13062) relied on a single in memory "pending" cluster state that is only processed by ZenDiscovery once committed by the master. While this is fine on it's own, it resulted in an issue with acknowledged APIs, such as the open index API, in the extreme case where a node falls behind and receives a commit message after a new cluster state has been published. Specifically:
1) Master receives and acked-API call and publishes cluster state CS1
2) Master waits for a min-master nodes to receives CS1 and commits it.
3) All nodes that have responded to CS1 are sent a commit message, however, node N didn't respond yet
4) Master waits for publish timeout (defaults to 30s) for all nodes to process the commit. Node N fails to do so.
5) Master publishes a cluster state CS2. Node N responds to cluster state CS1's publishing but receives cluster state CS2 before the commit for CS1 arrives.
6) The commit message for cluster CS1 is processed on node N, but fails because CS2 is pending. This caused the acked API in step 1 to return (but CS2 , is not yet processed).
In this case, the action indicated by CS1 is not yet executed on node N and therefore the acked API calls return pre-maturely. Note that once CS2 is processed but the change in CS1 takes effect (cluster state operations are safe to batch and we do so all the time).
An example failure can be found on: http://build-us-00.elastic.co/job/es_feature_two_phase_pub/314/
This commit extracts the already existing pending cluster state queue (processNewClusterStates) from ZenDiscovery into it's own class, which serves as a temporary container for in-flight cluster states. Once committed the cluster states are transferred to ZenDiscovery as they used to before. This allows "lagging" cluster states to still be successfully committed and processed (and likely to be ignored as a newer cluster state has already been processed).
As a side effect, all batching logic is now extracted from ZenDiscovery and is unit tested.
This commit removes all the optional injects etc. for the FetchServices and

to AbstractQueryTestCase to support GET calls in query tests.

The semantics of the `boost` parameter for `function_score` changed. This is
due to the fact that Lucene now requires that query boosts and top-level boosts
are applied the same way.
Requesting a million hits, or page 100,000 is always a bad idea, but users
may not be aware of this. This adds a per-index limit on the maximum size +
from that can be requested which defaults to 10,000.
This should not interfere with deep-scrolling.

This commit addresses several bugs that prevented the Windows
service from being started or stopped:
- Extra white space in the concatenation of java options in
elasticsearch.in.bat which tripped up Apache Commons Daemon
and caused ES to startup without any params, eventually leading
to the "path.home is not configured" exception.
- service.bat was not passing the start argument to ES
- The service could not be stopped gracefully via the stop command
because there wasn't a method for procrun to call.

Previously the parser could take any Term Vectors request, but this would be
not the case of the builder which would still use MultiGetRequest.Item. This
introduces a new Item class which is used by both the builder and parser.
Beyond that the rest is mostly cleanups such as:
1) Deprecating the ignoreLike methods, in favor to using unlike.
2) Deprecating and renaming MoreLikeThisBuilder#addItem to addLikeItem.
3) Ordering the methods of MoreLikeThisBuilder more logically.

1) A shared immutable fieldtype for the _parent field (used for direct access to that field in the dsl). This field type is stored and indexed.
2) A per type field type for the child join field. The field type has doc values enabled if index is created on or post 2.0 and field data type is allowed to be changed.
3) A per type field type for the parent join field. The field type has doc values enabled if index is created on or post 2.0.
This resolves the issue that a mapping is not compatible if parent and child types have different field data loading settings.

When we commit the translog, documents that were in it before cannot be retrieved from

in which we cannot read from the translog anymore but also not from the index.

This is an intial commit that splits HasChildQueryParser / Builder into

it's a start to get the code out there.
Whe we call optimize we ignore Exceptions that indicate a closed shard.
However, when a shard is closed while an optimize request is in flight it
might also trigger an AlreadyClosedException from the IndexWriter when we
get the config or ForceMergeFailedEngineException with the EngineClosedException
wrapped inside. Because these are not identified as exceptions that indicate
a closed shard (TransportActions.isShardNotAvailableException(..)) optimize
would sometimes report failures when shards were relocating while optimize was called
and sometimes not. This caused weird test failures, see #13266 .
Instead, we should let EngineClosedException bubble up and also recognize
AlreadyClosedException as an indicator for a closed shard.
Today we try to allocate primaries first and then replicas
but don't take the index creation date and priority into account
as we do in the GatewayAlloactor.

Adds a listeners to each of the caches that allows us to remove the dependency on IndexService which is cyclic since
the IndexService depends on both of these caches. This cyclic dependency makes

Transport clients run embedded within external applications, so

This change makes a number of cleanups to the internal API for loading

removed, since it was always true except for tests. We now always
attempt to load settings from config a file when an environment is

prepareSettingsAndEnvironment which nodes use, and prepareSettings which
the transport client uses. I also attempted to improve the tests, but
there is a still a lot of follow up work to do there.

Previously we skip deleting the index store for indices on a shared
filesystem, because we don't want to delete the data when the shard is
relocating around the cluster. This adds a flag to the

we should allow deleting the contents even if it is on a shared
filesystem.
Includes a unit test for the IndicesService.canDeleteIndexContents and
integration tests ensure a closed shadow replica index deletes files
correctly.

As a refinement to Project Coin (JEP-213, JDK-8042880), Java 9 is going
to disallow the use of ‘_’ as a one-character identifier. This will be
done by adding ‘_’ as a keyword to the Java language (JDK-8065599).
Currently, uses of ‘_’ as a one-character identifier are warnings in
the Java 8 compiler. This commit removes all uses of ‘_’ as a
one-character identifier from the codebase.
SpanContainingQueryParser and SpanWithinQueryParser always set the boost to the parsed lucene query, even if it is the default one. The default boost of the main query though is the boost coming from the inner little query, value that we end up overriding all the time. We should instead set the boost to the main query only if it differs from the default, to mimic lucene's behaviour.
Relates to #13272Closes#13339
SimpleQueryStringParser applies whatever boost the query holds, even if the default 1, to the query obtained from parsing of the query string. that might contain its boost, for instance if it resolved to a simple query like term (single term query against a single field). We should rather multiply the existing boost with the boost set to the query, same as we do in query_string

doParse() was supposed to allow aggs to perform extra parsing. Unfortunately, this forced the
parser to carry instance-level state, which would carry-over and "corrupt" any other aggs of the
same type in the same query.
Instead, we are now collecting all unknown params and pasing them as a Map<String, Object>
to buildFactory(). The agg may then parse them and instantiate a factory. Each param the
agg uses, it should unset from the unusedParams object.
After building the factory, the parser verifies that unusedParams is empty. If it is not empty,
an exception is raised so the user knows they provided unknown params.
Fixes#13337
This changes construction of Phrase and Boolean queries to use the builder,
and replaces BitDocIdSetFilter with BitSetProducer for nested and parent/child
queries. I had to remove the ParentIdsFilter for the case when there was a
single parent as it was using the source of BitSets for parents as a regular
Filter, which is not possible anymore now. I don't think this is an issue since
this case rarely occurs, and the alternative logic for when there are several
matching parent ids should not be much worse.
This pipeline will calculate percentiles over a set of sibling buckets. This is an exact
implementation, meaning it needs to cache a copy of the series in memory and sort it to determine
the percentiles.
This comes with a few limitations: to prevent serializing data around, only the requested percentiles
are calculated (unlike the TDigest version, which allows the java API to ask for any percentile).
It also needs to store the data in-memory, resulting in some overhead if the requested series is
very large.
This commit moves ignore_malformed and coerce options from the GeoPointFieldType to the Builder in GeoPointFieldMapper. This makes these options consistent with other types in 2.0.

Broadcast is an ipv4 only thing, the only way you can really detect its a broadcast

We have some optimization in FilteredQueryParser that tries to mimic what the rewrite method in lucene does, based on what gets parsed we return the simplest query possible. That might cause issues with boost values though, if specified in both the main query and the inner query that we shortcut to. We should rather rely on lucene's rewrite method to simplify the lucene representation of the query, and always build a filtered query instead.

We currently optimize scroll when sort=_doc because docs are returned in order.
But documents are also returned in order when sorting by score and the query
gives constant scores. This optimization has the nice side-effect of also
optimizing scrolls with the default `match_all` query.
Until now we had a cloud-aws plugin which is providing 2 disctinct features:
* discovery on EC2
* snapshot/restore on S3
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
Before this change the check would check that all test classes end in Tests but the message would say they need to end in Test or Tests which was confusing.
