Transitive dependencies can be confusing and hard to deal with when
conflicts arise between them. This change removes transitive
dependencies from elasticsearch, and forces any dependency conflicts to
be resolved manually, instead of automatically by gradle.

This allows different circuit breakers to have different logging levels.
It's useful when diagnosing problems (say for instance with the
fielddata breaker) and not seeing the enormous amount of logging from
the request breaker.
The log messages use the breaker name for logging, so example logging
will look like:
```
[2015-11-10 09:51:52,993][TRACE][indices.breaker.fielddata] [fielddata] Adding [27b][body] to used bytes [new used: [27b], limit: 623326003 [594.4mb], estimate: 27 [27b]]

`AbstractLegacyBlobContainer` was kept for historical reasons (see #13434).
We can migrate Azure and S3 repositories to use the new methods added in #13434 so we can remove `AbstractLegacyBlobContainer` class.
We only passed the engine config since we had no chance to get the cache
etc. from the IndexSearcher. Now that we have these getters we can just pass the
searcher instead.
Some dependencies must be specified in a couple places in the build.
e.g. randomized runner is specified both in buildSrc (for the gradle
wrapper plugin), as well as in the test-framework.
This change creates buildSrc/versions.properties which acts similar to
the set of shared version properties we used to have in the maven parent
pom.
This adds the `cluster.routing.allocation.total_shards_per_node`
setting, which limits the total number of shards across all indices on
each node. It defaults to -1 and can be dynamically configured.

GeoDistanceRangeQueryTest was using an inconsistent tolerance when validating from=0 with include_lower/upper set to false. This commit changes the assertion such that validation is consistent with builder logic.
- Same as for TransportInstanceSingleOperationAction and TransportReplicationAction, onClusterServiceClose consistently throws a NodeClosedException now.
- Added retry logic if master could not publish cluster state or stepped down before publishing (ZenDiscovery). The test IndexingMasterFailoverIT shows the issue.
- Simplified retry logic by moving bits from different places into shared retry method.
- Removed boolean flag retrying that aborted retrying after a single master node change (now we retry until timeout).
- Two existing predicates that deal with master node changes unified in a single predicate masterNodeChangedPredicate
Closes#14222
We used to test only json parsing as we relied on QueryBuilder#toString which uses the json format. This commit makes sure that we now output the randomly generated queries using a random format, and that we are always able to parse them correctly.
This revealed a couple of issues with binary objects that haven't been migrated yet to be structured Writeable objects. We used to keep them in the format they were sent while parsing, which led to problems when printing them out as we expected them to always be in json format. Also we can't compare different BytesReference objects that hold the same content but in different formats (unless we want to parse them as part of equal and hashcode, doesn't seem like a good idea) and verify that we have parsed the right objects if they can be different formats. The fix is to always keep binary objects in json format. Best fix would be not to have binary objects, which we'll get to once we are done with the search refactoring.
Closes#14415
Latest version of lucene deprecated Query#setBoost and Query#getBoost which made queries effectively immutable. Those methods need to be replaced with `BoostQuery` that wraps any query that needs boosting.
This commit replaces usages of setBoost with BoostQuery and adds it to forbidden-apis for prod code.
Usages of `getBoost` are only partially removed, as some will have to stay for backwards compatibility.
Closes#14264
If you run tests under a 32-bit jvm, you will get a test failure in IndexStoreTests,
the logic there is wrong in the case of 32-bit (its NIOFSDirectory on linux).
Also if mlockall fails, you'll see huge bogus values (because of use of `long` instead of `NativeLong`)
finally add seccomp support for 32 bit too, and clean up all its `long` usage as well.
run.sh and run.bat were calling out to the old maven build system.
This is no longer in place, so we've created new gradle tasks to
start an elasticsearch node from the current codebase.

Fix Build to correctly treat URLs and to not leak a file handle
Eclipse does not have the ability to differentiate test dependencies
from main dependencies. This causes what looks like a circular
dependency through test-framework. This change sets up an additional
core-tests project for eclipse only, which removes this problem.
This commit prevents running rebalance operations if the store allocator is
still fetching async shard / store data to prevent pre-mature rebalance decisions
which need to be reverted once shard store data is available. This is typically happening
on rolling restarts which can make those restarts extremely painful.
Closes#14387
This commit adds the abstraction layer to GeoPointFieldMapper needed to cut over to Lucene 5.4's new GeoPointField type while maintaining backward compatibility with 'legacy' geo_point indexes.
This commit addresses an issue in TransportBroadcastByNodeAction.
Namely, if in between a master leaving the cluster and a new one being
assigned, a request that relies on TransportBroadcastByNodeAction
(e.g., an indices stats request) is issued,
TransportBroadcastByNodeAction might attempt to send a request to a
node that is no longer in the local node’s cluster state.
The exact circumstances that lead to this are as follows. When the
master leaves the cluster and another node’s master fault detection
detects this, the local node will update its local cluster state to no
longer include the master node. However, the routing table will not be
updated. This means that in the preparation for sending the requests in
TransportBroadcastByNodeAction, we need to check that not only is a
shard assigned, but also that it is assigned to a node that is still in
the local node’s cluster state.
This commit adds such a check to the constructor of
TransportBroadcastByNodeAction. A new unit test is added that checks
that no request is sent to the master node in such a situation; this
test fails with a NullPointerException without the fix. Additionally,
the unit test TransportBroadcastByNodeActionTests#testResultAggregation
is updated to also simulate a master failure. This updated test also
fails prior to the fix.
Closes#14584
if we set the inactive time for the shard via API the entire test if fully time

This commit restores the build properties provided in
org.elasticsearch.Build. This class previously obtained the build hash
and timestamp from a resource es-build.properties that was included in
the jar and produced by the Maven resources plugin. After the switch to
Gradle, the production of this file was lost and these build properties
defaulted to “NA” in all instances.
The most important place that the build hash is used is in the plugin
manager to determine the URL of staging artifacts for plugins.
The build hash is also used in several responses including the /_nodes
response and the response to HTTP GET requests on the root path.
These properties can now be obtained from the jar manifest as they are
currently placed there by the gradle-info plugin. However, only the
short hash is provided. We now read the manifest for these properties
and no longer provide the full hash in responses to HTTP GET requests
on the root path.
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).

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.
Relates to #10974
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
https://github.com/randomizedtesting/gradle-randomized-testing-plugin.
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.

Furthermore, there are all kinds of checks for this case

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.

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.

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.
Closes#14028
The NotQueryBuilder has been deprecated on the 2.x branches
and can be removed with the next major version. It can be
replaced by boolean query with added mustNot() clause.
Closes#13761
This commit replaces instances of manually computing a hash code for
primitive longs by XORing the upper bits with the lower bits with a
built-in method for doing the same.
This adds an API for force merging lucene segments. The `/_optimize` API is now
deprecated and replaced by the `/_forcemerge` API, which has all the same flags
and action, just a different name.
