Originally, only numeric values were allowed for parameters of the
'geohash_grid' aggregation in contrast to other places in the REST
API.
With this commit we also allow that parameters are enclosed in quotes (i.e.
as JSON strings). Additionally, with this commit the valid range for
'precision' is enforced for the Java API and the REST API (the latter was
previously missing the check).

query_binary and filter_binary are unused at this point, as we only parse on the coordinating node and the java api only holds structured java objects for queries and filters, meaning they all implement Writeable and get natively serialized.

This commit fixes a bug in cat thread pool. This bug resulted from a
refactoring of the handling of thread pool types. To get the previously
displayed thread pool type from the ThreadPoolType object,
ThreadPoolType#getType needs to be called.
Reverting fix for #13884 because it was discussed to be too
fragile with respect to future changes in lucene simple query
string parsing. Undoes fix and removes test.
If we have a shard failure on SearchPhaseExecutionException
we can deduplicate the original cause and use the more informative
ShardSearchFailure containing the shard ID etc. but we should deduplicate
the actual cause to prevent stack trace duplication.
This commit forbids the changing of thread pool types for any thread
pool. The motivation here is that these are expert settings with
little practical advantage.

IndexQueryParserService is only a factory for QueryShardContext instances
which are not even bound to a shard. The service only forwards dependencies and even
references node level service directly which makes dependency seperation on shard,
index and node level hard. This commit removes the service entirely, folds the creation
of QueryShardContext into IndexShard which is it's logical place and detaches the
ClusterService needed for index name matching during query parsing with a simple predicate
interface on IndexSettings.
This PR adds a randomized test to the query test base class
that mutates an otherwise correct query by adding an additional
object into the query hierarchy. Doing so makes the query illegal
and should trigger some kind of exception. The new test revelead
that some query parsers quietly return queries when called with
such an illegal query. Those are also fixed here.

Similarly to what we did with the search api, we can now also move query parsing on the coordinating node for the validate query api. Given that the explain api is a single shard operation (compared to search which is instead a broadcast operation), this doesn't change a lot in how the api works internally. The main benefit is that we can simplify the java api by requiring a structured query object to be provided rather than a bytes array that will get parsed on the data node. Previously if you specified a QueryBuilder it would be serialized in json format and would get reparsed on the data node, while now it doesn't go through parsing anymore (as expected), given that after the query-refactoring we are able to properly stream queries natively. Note that the WrapperQueryBuilder can be used from the java api to provide a query as a string, in that case the actual parsing of the inner query will happen on the data node.

The RR gradle plugin is at

However, we currently have a copy of this, since the plugin is still in
heavy development. This change moves the files around so they can be
copied directly from the elasticsearch fork to that repo, for ease of
syncing.
Removes the mapping transform feature which when used made debugging very
difficult. Users should transform their documents on the way into
Elasticsearch rather than having Elasticsearch do it.
Closes#12674
Most query parsers throw a ParsingException when they trying
to parse a field with an unknown name. This adds a generic
check for this to the AbstractQueryTestCase so the behaviour
gets tested for all query parsers. The test works by first
making sure the test query has a `boost` field and then
changing this to an unknown field name and checking for an
error.
There are exceptions to this for WrapperQueryBuilder
and QueryFilterBuilder, because here the parser only expects
the wrapped `query` element. MatchNoneQueryBuilder and
MatchAllQueryBuilder so far had setters for boost() and
queryName() but didn't render them, which is added here for
consistency.
GeoDistance, GeoDistanceRange and GeoHashCellQuery so far
treat unknown field names in the json as the target field name
of the center point of the query, which so far was handled by
overwriting points previously specified in the query. This
is changed here so that an attempt to use two different field names
to specify the central point of the query throws a
ParsingException

This change moves all the analysis component registration to the node level
and removes the significant API overhead to register tokenfilter, tokenizer,
charfilter and analyzer. All registration is done without guice interaction such
that real factories via functional interfaces are passed instead of class objects
that are instantiated at runtime.
This change also hides the internal analyzer caching that was done previously in the
IndicesAnalysisService entirely and decouples all analysis registration and creation
from dependency injection.
This change removes the leftover pom files. A couple files were left for
reference, namely in qa tests that have not yet been migrated (vagrant
and multinode). The deb and rpm assemblies also still exist for
reference when finishing their setup in gradle.
See #13930
The test jar was previously built in maven by copying class files. With

Add threadgroup isolation.
Code with `modifyThread` and `modifyThreadGroup` may only modify
its own threadgroup (or an ancestor of that). This enforces
what is intended by the ThreadGroup class.
This has two immediate implications:
1. Code without these permissions (scripts) may not create or mess with threads
2. ES application threads cannot mess with Java system threads
ES puts all application threads in one single group today, but in the future
this can be organized better, and we will have more isolation in the system.
This commit fixes two issues that could arise when a loader throws an
exception during a load in Cache#computeIfAbsent.
The underlying issue is that if the loader throws an exception,
Cache#computeIfAbsent would attempt to remove the polluted entry from
the cache. However, this cleanup was performed outside of the segment
lock. This means another thread could race and expire the polluted
entry (leading to NPEs) or get a polluted entry out of the cache before
the loading thread had a chance to cleanup (leading to ISEs).
The solution to the initial problem of correctly handling failed cached
loads is to check for failed loads in all places where entries are
retrieved from the map backing the segment. In such cases, we treat it
as if there was no entry in the cache, and we clean up the cache on a
best-effort basis. All of this is done outside of the segment lock to
avoid reintroducing the deadlock that was initially a problem when
loads were executed under a segment lock.
This commit adds a unit test for a deadlock issue that existed prior to
commit 1d0b93f766. While commit
1d0b93f766 seems to have addressed the
deadlock issue it would be more robust to have a unit test for it and a
unit test will reduce the risk that future maintenance on Cache will
reintroduce the deadlock issue. This test reliably fails prior to but
passes after commit 1d0b93f766.
Currently a `simple_query_string` query with one term and multiple fields
gets parsed to a BooleanQuery where the number of clauses is determined
by the number of fields, which lead to wrong calculation of `minimum_should_match`.
This PR adds checks to detect this case and wrap the resulting BooleanQuery into
another BooleanQuery with just one should-clause, so `minimum_should_match`
calculation is corrected.
In order to differentiate between the case where one term is queried across
multiple fields and the case where multiple terms are queried on one field,
we override a simplification step in Lucenes SimpleQueryParser that reduces
a one-clause BooleanQuery to the clause itself.
Closes#13884
This commit adds a listener mechanism for executing callbacks when
exceptional situations occur sending a shard failure message to the
master. The two types of exceptional situations that can occur are if
the master is not known and if the transport request exception handler
is invoked for any reason after sending the shard failed request to the
master. This commit only adds the infrastructure for executing
callbacks when one of these exceptional situations occur; no effort is
made to properly handle the exceptional situations. Some unit tests are
added for ShardStateAction to test that the listener infrastructure is
correct.

This is not needed: full mvn verify passes.
Furthermore, there are all kinds of checks for this case

is no need to have it here. If its supposed to be non-fatal,
then we add the missing places to the actual code, not globally to all threads.

On _lastWriteNanos_ we use System.nanoTime() to initialize this since:
* we use the value for figuring out if the shard / engine is active so if we startup and no write has happened yet we still consider it active
for the duration of the configured active to inactive period. If we initialize to 0 or Long.MAX_VALUE we either immediately or never mark it
inactive if no writes at all happen to the shard.
* we also use this to flush big-ass merges on an inactive engine / shard but if we we initialize 0 or Long.MAX_VALUE we either immediately or never
commit merges even though we shouldn't from a user perspective (this can also have funky sideeffects in tests when we open indices with lots of segments
and suddenly merges kick in.
This method needs special permission and can cause all kinds of other problems
if we are creating lots of theads. Also the reason why we added this are fixed
long ago, no need to maintain this code.
This commit fixes a regression introduced with #12058. This causes failures with the delete index api when providing the same index name multiple times in the request, or aliases/wildcard expressions that end up pointing to the same concrete index. The bug was revealed after merging #11258 as we delete indices in batch rather than one by one. The master node will expect too many acknowledgements based on the number of indices that it's trying to delete, hence the request will never be acknowledged by all nodes.
Closes#14316
We have two types of parse methods for queries: one for the inner query, to be used once the parser is positioned within the query element, and one for the whole query source, including the query element that wraps the actual query.
With the search refactoring we ended up using the former in count, cat count and delete by query, whereas we should have used the former. It ends up working properly given that we have a registered (deprecated) query called "query", which used to allow to wrap a filter into a query, but this has the following downsides:
1) prevents us from removing the deprecated "query" query
2) we end up supporting a top level query that is not wrapped within a query element (pre 1.0 syntax iirc that shouldn't be supported anymore)
This commit finally removes the "query" query and fixes the related parsing bugs. We also had some tests that were providing queries in the wrong format, those have been fixed too.

This commit makes QueryCache and SearcherWrappoer registration public

separates the Engine from the warmer.
This changes how `min_score` is implemented both for `function_score` and the

Today if a shard is marked as inactive after a heavy indexing period
large merges are very likely. Yet, those merges are never committed today
since time-based flush has been removed and unless the shard becomes active
again we won't revisit it.
Yet, inactive shards have very likely been sync-flushed before such that we need
to maintain the sync id if possible which this change tries on a per shard basis.
The test spawns up 3 nodes, waits for a master to be elected and starts network disruptions. If those kick in too early we may have a cluster with a state not recovered block which causes failure during clean ups. http://build-us-00.elastic.co/job/es_core_master_oracle_6/3034/

We should not implement this method, it is a real problem. But I think
it is ok to workaround the JDK bug (https://bugs.openjdk.java.net/browse/JDK-8014008).
This allows jconsole/visualvm to work in the meantime.
The @IndexSettings annoationat has been used to differentiate between node-level
and index level settings. It was also decoupled from realtime-updates such that
the settings object that a class got injected when it was created was static and
not subject to change when an update was applied. This change removes the annoation
and replaces it with a full-fledged class that adds type-safety and encapsulates additional
functionality as well as checks on the settings.
Today IndicesLifecycle is a per-node class that allows to register
listeners at any time. It also requires to de-register if listeners
are not needed anymore ie. if classes are created per-index / shard etc.
They also cause issues where listeners are registered more than once as in #13259
This commit removes the per-node class and replaces it with an well defined
extension point that allows listeners to be registered at index creation time
without the need to unregister since listeners are go out of scope if the index
goes out of scope. Yet, this still allows to share instances across indices as before
but without the risk of double registering them etc.
All data-structures used for event notifications are now immuatble and can only changes
on index creation time. This removes flexibility to some degree but increases maintainability
of the interface and the code itself dramatically especially with the step by step removal of
the index level dependency injection.
Closes#13259
The ExtensionPoint.ClassSet binds adds the extension classes to a a Multibinder and binds

Numeric and boolean fields have doc values enabled by default as of
elasticsearch 2.0. This commit removes support for uninverted/in-memory
fielddata, as well as numeric fields encoded in binary doc values which was
the way that elasticsearch stored doc values in a Lucene index before the
1.4 release.
As a consequence, you will only be able to sort and aggregate on numeric and
boolean fields in Elasticsearch 3.0 if doc values have not been switched off.
With #13691 we introduced some custom logic to make sure that date math expressions like <logstash-{now/D}> don't get broken up into two where the slash appears in the expression. That said the only correct way to provide such a date math expression as part of the uri would be to properly escape the '/' instead. This fix also introduced a regression, as it would make sure that unescaped '/' are handled only in the case of date math expressions, but it removed support for properly escaped slashes anywhere else. The solution is to keep supporting escaped slashes only and require client libraries to properly escape them.
This commit reverts 93ad696 and makes sure that our REST tests runner supports escaping of path parts, which was more involving than expected as each single part of the path needs to be properly escaped. I am not too happy with the current solution but it's the best I could do for now, maybe not that concerning anyway given that it's just test code. I do find uri encoding quite frustrating in java.

There are three ways `@Test` was used. Way one:
```java
@Test
public void flubTheBlort() {
```
This way was always replaced with:
```java
public void testFlubTheBlort() {
```
Or, maybe with a better method name if I was feeling generous.
Way two:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
methodThatThrows();
}
```
This way of using `@Test` is actually pretty OK, but to get the tools to ban
`@Test` entirely it can't be used. Instead:
```java
public void testFoo() {
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
This is longer but tests more than the old ways and is much more precise.
Compare:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
methodThatThrows();
code(); // <---- This was left here by mistake and is never called
}
```
to:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
The final use of test is:
```java
@Test(timeout=1000)
public void testFoo() {
methodThatWasSlow();
}
```
This is the most insidious use of `@Test` because its tempting but tragically
flawed. Its flaws are:
1. Hard and fast timeouts can look like they are asserting that something is
faster and even do an ok job of it when you compare the timings on the same
machine but as soon as you take them to another machine they start to be
invalid. On a slow VM both the new and old methods fail. On a super-fast
machine the slower and faster ways succeed.
2. Tests often contain slow `assert` calls so the performance of tests isn't
sure to predict the performance of non-test code.
3. These timeouts are rude to debuggers because the test just drops out from
under it after the timeout.
Confusingly, timeouts are useful in tests because it'd be rude for a broken
test to cause CI to abort the whole build after it hits a global timeout. But
those timeouts should be very very long "backstop" timeouts and aren't useful
assertions about speed.
For all its flaws `@Test(timeout=1000)` doesn't have a good replacement __in__
__tests__. Nightly benchmarks like http://benchmarks.elasticsearch.org/ are
useful here because they run on the same machine but they aren't quick to check
and it takes lots of time to figure out the regressions. Sometimes its useful
to compare dueling implementations but that requires keeping both
implementations around. All and all we don't have a satisfactory answer to the
question "what do you replace `@Test(timeout=1000)`" with. So we handle each
occurrence on a case by case basis.
For files with `@Test` this also:
1. Removes excess blank lines. They don't help anything.
2. Removes underscores from method names. Those would fail any code style
checks we ever care to run and don't add to readability. Since I did this manually
I didn't do it consistently.
3. Make sure all test method names start with `test`. Some used to end in `Test` or start
with `verify` or `check` and they were picked up using the annotation. Without the
annotation they always need to start with `test`.
4. Organizes imports using the rules we generate for Eclipse. For the most part
this just removes `*` imports which is a win all on its own. It was "required"
to quickly remove `@Test`.
5. Removes unneeded casts. This is just a setting I have enabled in Eclipse and
forgot to turn off before I did this work. It probably isn't hurting anything.
6. Removes trailing whitespace. Again, another Eclipse setting I forgot to turn
off that doesn't hurt anything. Hopefully.
7. Swaps some tests override superclass tests to make them empty with
`assumeTrue` so that the reasoning for the skips is logged in the test run and
it doesn't "look like" that thing is being tested when it isn't.
8. Adds an oxford comma to an error message.
The total test count doesn't change. I know. I counted.
```bash
git checkout master && mvn clean && mvn install | tee with_test
git no_test_annotation master && mvn clean && mvn install | tee not_test
grep 'Tests summary' with_test > with_test_summary
grep 'Tests summary' not_test > not_test_summary
diff with_test_summary not_test_summary
```
These differ somewhat because some tests are skipped based on the random seed.
The total shouldn't differ. But it does!
```
1c1
< [INFO] Tests summary: 564 suites (1 ignored), 3171 tests, 31 ignored (31 assumptions)
---
> [INFO] Tests summary: 564 suites (1 ignored), 3167 tests, 17 ignored (17 assumptions)
```
These are the core unit tests. So we dig further:
```bash
cat with_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > with_test_suites
cat not_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > not_test_suites
diff <(sort with_test_suites) <(sort not_test_suites)
```
The four tests with lower test numbers are all extend `AbstractQueryTestCase`
and all have a method that looks like this:
```java
@Override
public void testToQuery() throws IOException {
assumeTrue("test runs only when at least a type is registered", getCurrentTypes().length > 0);
super.testToQuery();
}
```
It looks like this method was being double counted on master and isn't anymore.

Rather than make a new exception this improves the error message of the old

MetaDataSerivce tried to protect concurrent index creation/deletion
from resulting in inconsistent indices. This was originally added a
long time ago via #1296 which seems to be caused by several problems
that we fixed already in 2.0 or even in late 1.x version. Indices where
recreated without being deleted and shards where deleted while being used
which is now prevented on several levels. We can safely remove the semaphores
since we are already serializing the events on the cluster state threads.

After a full cluster restart, the elected master is tasked with recovery the last known cluster state from disk. To do so, the GatewayService registers it self as a listener to cluster state changes, triggering the recovery if the local node is elected. Sadly the initial post-election cluster state can be missed if it's being processed while the listener is registered (i.e., the listener is too late but the discoveryService.initialStateReceived is not yet set). In this case the cluster state from disk will be recovered with the next change (typically node join).
In practice this is not a big deal as master election takes at least 3s (by which time the gateway is long started), but it does make some of our tests to fail: http://build-us-00.elastic.co/job/es_core_master_centos/7915/

but if we are parsing embedded search sources this won't work since we potentially
moved already on to the START_OBJECT. This commit make this optional such that
both ways work.
We can't track disk usage in this situation, failing is the correct thing to do.
But we can give a FreeBSD-specific error message, so the user can set the
necessary jail parameters, versus a vague IOException.

Test that the lucene "unmap hack" is supported.
We should know if this is not working for any configuration, otherwise resources such as address space, file handles, and even disk space become tied to Java's garbage collector.
This test failed only on a feature branch, because that feature branch has
a different build randomization script and is the only place
randomizing tests.security.manager (this test cannot run with it enabled).
On old kernels without TSYNC support, the test fails because (surprise to me) the thread that
runs the test is not the same thread that runs static initializers:
7571489190/randomized-runner/src/main/java/com/carrotsearch/randomizedtesting/RandomizedRunner.java (L573-L574)
To fix this test (its not an issue in practice, since we do this before creating threadpools),
we just record for testing purposes that we couldn't TSYNC, and re-run the whole thing for the test thread
in setUp(), failing if something goes wrong.
Also add a bunch of additional paranoia and narrow our defensive checks better here after reading
through more chrome bug reports: they don't impact us but those linux distros are too cowboy
with the backports and the spirit of the checks makes me feel better.
This commit adds a new metric aggregator for computing the geo_centroid over a set of geo_point fields. This can be combined with other aggregators (e.g., geohash_grid, significant_terms) for computing the geospatial centroid based on the document sets from other aggregation results.
This commit cleans up IndexMetaData. In particular, all duplicate
getters (X and getX) have been collapsed into one (getX). Further, the
number of shards and number of replicas settings are now parsed once
and saved off as fields.
* Add ability for plugins to declare additional permissions with a custom plugin-security.policy file and corresponding AccessController logic. See the plugin author's guide for more information.
* Add warning messages to users for extra plugin permissions in bin/plugin.
* When bin/plugin is run interactively (stdin is a controlling terminal and -b/--batch not supplied), require user confirmation.
* Improve unit test and IDE support for plugins with additional permissions by exposing plugin's metadata as a maven test resource.

Decentralize plugin permissions (modulo docs and pluginmanager work)
This commit makes sure that the plugin script looks at user, group and permissions of the elasticsearch bin dir and copies them over to the plugin bin subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed. We also make sure that execute permissions are added for files (we already did this before).
Relates to #11016Closes#14088
Today we leak an index searcher if we fail to wrap the seacher in
IndexShard. This commit ensures that the seacher is released if the wrapper
throws an exception.
This commit also restructures some test to be more atomic and only test a single
feature / attribute of the wrapper.
This commit changes the behavior of Cache#computeIfAbsent to not invoke
load for a key under the segment lock. Instead, the synchronization
mechanism to ensure that load is invoked at most once per key is
through the use of a future. Under the segment lock, we put a future in
the cache and through this ensure that load is invoked at most once per
key. This will not lead to the same deadlock situation as before
because a dependent key load on the same thread can not be triggered
while the segment lock is held.
Closes#14090
We randomly use the WindowsFS mock file system to simulate that
windows does not delete files if they are opened by some other
process and instead gives you java.io.IOException: access denied.
In the tests we also check if the shard was deleted while it is
being deleted. This check loads the mata data of the index
and therefore might hold on to a file while the node
is trying to delete it and deletion will fail then.
Instead we should just check if the directory was removed.
closes#13758
this commit also fixes a bug where we wramed a leaf reader in a top level context
which caused atomic segment readers to be used in our top level caches.
IndexReader#addReaderCloseListener is very error prone when it comes to
caching and reader wrapping. The listeners are not delegated to the sub readers
nor can it's implementation change since it's final in the base class. This commit
only allows installing close listeners on the top level ElasticsearchDirecotryReader
which is known to work an has a defined lifetime which corresponds to its subreader.
This ensure that cachesa re cleared once the reader goes out of scope.
In #13606, the ability to exclude a template from being wiped was added but a call to
wipeTemplates() was not removed, so all index templates were still being removed.
This change removes the wipeTemplates() call in the wipe method so that only the
non-excluded templates are removed.
Depending on how elasticsearch is installed, we have two scenarios to take into account that relate to user, group and permissions assigned to the config directory:
1) deb/rpm package: /etc/elasticsearch is root:elasticsearch 750 and the plugin script is run from root user
2) tar/zip archive: es config dir is most likely elasticsearch:elasticsearch and the plugin script is most likely run from elasticsearch user
When the plugin script copies over the plugin config dir within the es config dir, it should take care of setting the proper user, group and permissions, which vary depending on how elasticsearch was installed in the first place. Should be root:elasticsearch 750 if installed from a package, or elasticsearch:elasticsearch if installed from an archive.
This commit makes sure that the plugin script looks at user, group and permissions of the config dir and copies them over to the plugin config subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed in the first place. We also make sure that execute permissions are left untouched for files.

make the version map cache per-segment
This commit adds methods to serialize the elements of int and long
arrays using variable-length encodings. This can be useful for
serializing int and long arrays containing mostly non-negative “not
large” values in a compressed form.
