For the search refactoring the HighlightBuilder needs a way to
create new instances by parsing xContent. For bwc this PR start
by moving over and slightly modifying the parsing from
HighlighterParseElement and keeps parsing for top level highlighter
and field options separate. Also adding tests for roundtrip
of random builder (rendering it to xContent and parsing it and
making sure the original builder properties are preserved)
Since 2.2 we run all scripts with minimal privileges, similar to applets in your browser.
The problem is, they have unrestricted access to other things they can muck with (ES, JDK, whatever).
So they can still easily do tons of bad things
This PR restricts what classes scripts can load via the classloader mechanism, to make life more difficult.
The "standard" list was populated from the old list used for the groovy sandbox: though
a few more were needed for tests to pass (java.lang.String, java.util.Iterator, nothing scary there).
Additionally, each scripting engine typically needs permissions to some runtime stuff.
That is the downside of this "good old classloader" approach, but I like the transparency and simplicity,
and I don't want to waste my time with any feature provided by the engine itself for this, I don't trust them.
This is not perfect and the engines are not perfect but you gotta start somewhere. For expert users that
need to tweak the permissions, we already support that via the standard java security configuration files, the
specification is simple, supports wildcards, etc (though we do not use them ourselves).
This commit simplifies shard inactive debug logging to only log when the
physical shard is marked as inactive. This eliminates duplicate logging
that existed in IndexShard#checkIdle and
IndexingMemoryController#checkIdle, and eliminates excessive logging
that was occurring when the shard was already inactive as a result of
the work in #15252.
Currently, when a user tries to install an old plugin (pre 2.x) on a 2.x
node, the error message is cryptic (just printing the file path that was
missing, when looking for the descriptor). This improves the message to
be more explicit that the descriptor is missing, and suggests the
problem might be the plugin was built before 2.0.

This commit addresses some issues that arose during the review of #14899
but were lost during squash while integrating into master.
- the number of test threads is dropped to at most eight
- a local variable is renamed for clarity
- task priorities are randomized
This commit fixes a test bug in
ClusterService#testClusterStateBatchedUpdates. In particular, in the
case that an executor did not receive a task assignment from the random
assignments, it would not have an entry in the map of executors to
counts of assigned tasks. The fix is to just check if each executor has
an entry in the counts map.
This commit modifies IndexingMemoryController to be stateless. Rather
than statefully tracking the indexing status of shards,
IndexingMemoryController can grab all available shards, check their idle
state, and then resize the buffers based on the number of and which
shards are not idle.
The driver for this change is a performance regression that can arise in
some scenarios after #13918. One scenario under which this performance
regression can arise is if an index is deleted and then created
again. Because IndexingMemoryController was previously statefully
tracking the state of shards via a map of ShardIds, the new shards with
the same ShardIds as previously existing shards would not be detected
and therefore their version maps would never be resized from the
defaults. This led to an explosion in the number of merges causing a
degradation in performance.
Closes#15225
Today we only check mapping compatibility when adding mappers to the
lookup structure. However, at this stage, the mapping has already been merged
partially, so we can leave mappings in a bad state. This commit removes the
compatibility check from Mapper.merge entirely and performs it _before_ we
call Mapper.merge.
One minor regression is that the exception messages don't group together errors
that come from MappedFieldType.checkCompatibility and Mapper.merge. Since we
run the former before the latter, Mapper.merge won't even have a chance to let
the user know about conflicts if conflicts were discovered by
MappedFieldType.checkCompatibility.
Close#15049
The `translated` flag makes LineStringBuilder stateful and gets set
to true under certain conditions when building a Shape or Geometry
from the ShapeBuilder. This makes building operations not be idempotent,
so calling build() more than once on a LineStringBuilder might change the
builder itself. This PR fixes this by replacing the instance variable by
a local `translated` flag that is only updated internally during the
building process and created again on any subsequent calls to build()
or buildGeometry().
Failures to merge a mapping can either come as a MergeMappingException if they
come from Mapper.merge or as an IllegalArgumentException if they come from
FieldTypeLookup.checkCompatibility. I think we should settle on one: this pull
request replaces all usage of MergeMappingException with
IllegalArgumentException.
The ttl could be specified as a time value only via the REST layer. That is now possible via java api too, either as a string or as a proper TimeValue. The internal format in IndexRequest becomes now TimeValue, which will then still converted to a long before storing the document.
Closes#15047
- Supports ImmutableOpenIntMap besides java.util.Map and ImmutableOpenMap
- Map keys can be any value (not only String)
- Map values do not have to implement Diffable interface. In that case custom value serializer needs to be provided.
Several settings have been deprecated or are replaced with new settings after refactorings
in version 1.x. This commit removes the support for these settings.
The settings are:
* `index.shard.recovery.translog_size`
* `index.shard.recovery.translog_ops`
* `index.shard.recovery.file_chunk_size`
* `index.shard.recovery.concurrent_streams`
* `index.shard.recovery.concurrent_small_file_streams`
* `indices.recovery.max_size_per_sec`
When not in debug mode, we currently only print the message of an
exception. However, this is not usually useful without knowing what the
exception type was. This change makes cli tools use toString() on the
exception so we get the type + message.
This commit wraps the trace logging statements in
TransportBroadcastByNodeAction in trace enabled checks to avoid
unnecessarily allocating objects.
The most egregious offenders were the two trace logging statements in
BroadcastByNodeTransportRequestHandler#onShardOperation. Aside from the
usual object allocations that occur when invoking ESLogger#trace (the
allocated object array for the varargs Object... parameter), these two
logging statements were invoking ShardRouting#shortSummary generating a
bunch of char arrays and Strings (from the StringBuilder, and so a bunch
of array copies as well). In a scenario where there are a lot of shards
and this method is being invoked frequently (e.g., constantly hitting
the _stats endpoint), these two unprotected trace logging statements
were generating a lot of unnecessary allocations.
This commit modifies the handling of shard started cluster state updates
to use the general cluster state batching mechanism. An advantage of
this approach is we now get correct per-listener notification on
failures.
This commit removes a simple early-out check in
MetaDataMappingService#executeRefresh. The early-out is unnecessary
because the cluster state task execution framework will not invoke
ClusterStateTaskExecutor#execute if the list of tasks is empty.
This commit updates a stale Javadoc on
MetaDataMappingService#executeRefresh. Previously this method handled
refresh and update tasks. Update tasks have been removed and the method
was renamed, but the Javadoc was not updated to reflect this.
This is due to the fact that the query cache will still call the
onDocIdSetEviction callback in this case but with a number of entries equal to
zero.
Close#15043
This commit removes and now forbids all uses of the type-unsafe empty
Collections fields Collections#EMPTY_LIST, Collections#EMPTY_MAP, and
Collections#EMPTY_SET. The type-safe methods Collections#emptyList,
Collections#emptyMap, and Collections#emptySet should be used instead.
Today we try to have type-level granularity when dealing with mappings. This
does not play well with the cross-type validations that we are adding. For
instance we prevent the `_parent` field to point to an existing type. This
validation would be skipped today in the case of dedicated master nodes, since
those master nodes would only create the type that is being updated when
updating a mapping.
In 1.x it is possible via index templates to create an index with an alias with the same name as the index. The index name must match the index template and have an alias with the same name as the index being created.
This change attempts to simplify the gradle tasks for precommit. One
major part of that is using a "less groovy style", as well as being more
consistent about how tasks are created and where they are configured. It
also allows the things creating the tasks to set up inter task
dependencies, instead of assuming them (ie decoupling from tasks
eleswhere in the build).
This adds safety that you can't index into the `_default_` type (it was possible
before), and can't add default mappers to the field type lookups (was not
happening in tests but I think this is still a good check).
Also MapperService.types() now excludes `_default` so that eg. the `ids` query
does not try to search on this type anymore.
This commit modifies the handling of shard failure cluster state updates
to use the general cluster state batching mechanism. An advantage of
this approach is we now get correct per-listener notification on

This change pulls out the common fields that HighlighterBuilder shares with

When creating an index on master for the purpose of updating mappings, a
mapping being updated could needlessly be merged multiple times. This
commit ensures that each mapping is merged at most once while preparing
to update mappings.
When creating an index on master for the purpose of updating mappings,
the default mapping could needlessly be added multiple times. This
commit ensures that the default mapping is added at most once while
preparing to update mappings.
This commit addresses an issues introduced in #14899 to apply mapping
updates in batches. The issue is that an existing mapping for a type
could be lost if that type came in a batch that already contained a
mapping update for another type on the same index. The underlying issue
was that the existing mapping would not be merged in because the merging
logic was only tripped once per index, rather than for all types seeing
updates for each index. Resolving this issue is simply a matter of
ensuring that all existing types seeing updates are merged in.
Closes#15129
The REST bulk API rejects use of `refresh` at the item level. But the Java API lets the user setting it.
We need to have the same behavior and don't let think the user he can define `refresh` per bulk item.
Note that the user can still define `refresh` on the bulk itself.
Also a user can create with Java API an IndexRequest without any source which is causing a NPE when evaluating the bulk item size.
Closes#7361.
Closes#15120.
I will followup with ITs and other modules. By fixing this, these tests become more reliable (will never sporatically
fail due to other stuff on your machine: ports are assigned by the OS), and it allows us to move forward with
gradle parallel builds, in my tests this is a nice speedup, but we can't do it until tests are cleaned up
This commit splits cluster state update tasks into roles. Those roles
are:
- task info
- task configuration
- task executor
- task listener
All tasks that have the same executor will be executed in batches. This
removes the need for local batching as was previously in
MetaDataMappingService.
Additionally, this commit reintroduces batching on mapping update calls.

Removed check that two query builder that are different according
to equals() have different hashCode since that is not required
by the contract of hashCode.
We used to check on several places if we are still open but non of these
places did the check under the lock which leaves a small window where we
potentially get closed but still access an already closed channel or another
IO resource.
This is a pretty trivial change that moves most of the monitor service related
object creation from guice into the monitor service. This is a babystep towards removing
guice on the node level as well. Instead of opening huge PRs I try to do this in baby-steps
that are easier to digest.
We handle AlreadyClosedExceptions gracefully wherever IndexShard / Engine
is used. In some cases, instead of throwing the appropriate exception we
bubble up ChannelClosedException instead which causes shard failures etc.
Today, it seems like that this can only happen if the engine is closed without
acquireing the lock which means that the shard has failed already so the impact is really
just a confusing log message. Yet, this change enforces throwing the right exception
if the translog is already closed.
Closes#14866
This moves the registration of field mappers from the index level to the node
level and also ensures that mappers coming from plugins are treated no
differently from core mappers.
This commit fixes some leniency in the parsing of CIDRs. The leniency
that existed before includes not validating the octet values nor
validating the network mask; in some cases issues with these values were
silently ignored. Parsing is now done according to the guidelines in RFC
4632, page 6.
Closes#14862
For example: if a node left the cluster and an async store fetch was triggered. In that time no shard is marked as delayed (and strictly speaking it's not yet delayed). This caused test for shard delays post node left to fail. see : http://build-us-00.elastic.co/job/es_core_master_windows-2012-r2/2074/testReport/
To fix this, the delay update is now done by the Allocation Service, based of a fixed time stamp that is determined at the beginning of the reroute.
Also, this commit fixes a bug where unassigned info instances were reused across shard routings, causing calculated delays to be leaked.
Closes#14890
This switches query parsing from manual field parsing to using ParseField.
Also adds unit tests for each query that check original json can be parsed
into query builders.
Relates to #8964
We recently refactored the queries to make them parsable on the
coordinating note and adding serialization and equals/hashCode
capability to them. So far ShapeBuilders nested inside queries
were still transported as a byte array that needs to be parsed
later on the shard receiving the query. To be able to also
serialize geo shapes this way, we also need to make all the
implementations of ShapeBuilder implement Writable.
This PR adds this to PointBuilder and also adds tests for
serialization, equality and hashCode.
The work for #10708 requires tighter integration with the current shard routing of a shard. As such, we need to make sure it is set before the IndexService exposes the shard to external operations.

Index constraints should remove indices in the response if the field to evaluate if empty. Index constraints can't work with that and it is the same as if the field doesn't match.
Currently we use the "gradle project attachment plugin" to support
building elasticsearch as part of another project. However, this plugin

extra-plugins directory in the root of elasticsearch. Any projects
checked out within this directory will be automatically added to
elasticsearch.

This makes AvgTests use a mock plugin engine. I also removed the
textScriptExplicit* methods for the base class since they only make sense for

After the removal of some internal shape builders in #14482 the
BaseLineStringBuilder has only one implementation, the LineStringBuilder.
Same for the BasePolygonBuilder. This PR removes the abstract classes
and merges them with their concrete implementation to simplify the
inheritance hierarchy.
The Ring subclass is just a LineStringBuilder that has an additional
close() method and keeps a reference to a parent shape builder so
builders can be chained. This PR removes it and replaces it by
using LineStringBuilder instead. The close() method is moved there
and tests are adapted.
This is a first step in reducing the number of ShapeBuilders since
before we start making the remaining implement Writable for the
search request refactoring. This shape builder seems to have been
only used in tests, and those tests didn't do much to begin with,
so this removed them.

stream indicates that no ShardId is present in the stream.
Additionally, the use of StreamOutput#writeOptionalStreamable is

This commit adds a method of encoding longs using a variable-length
representation. This encoding is an implementation of the zig-zag
encoding from protocol buffers. Numbers that have a small absolute value
will use a small number of bytes. This is achieved by zig-zagging
through the space of longs in order of increasing absolute value (0, -1,
1, -2, 2, …, Long.MAX_VALUE, Long.MIN_VALUE) -> (0, 1, 2, 3, 4, …, -2,
-1). The resulting values are then encoded as if they represent unsigned
numbers.

If we run out of disk while recoverying the transaction log
we repeatedly fail since we expect the latest tranlog to be uncommitted.
This change adds 2 safety levels:
* uncommitted checkpoints are first written to a temp file and then atomically
renamed into a committed (recovered) checkpoint
* if the latest uncommitted checkpoints generation is already recovered it has to be
identical, if not the recovery fails
This allows to fail in between recovering the latest uncommitted checkpoint and moving
the checkpoint generation to N+1 which can for instance happen in a situation where
we can run out of disk. If we run out of disk while recovering the uncommitted checkpoint
either the temp file writing or the atomic rename will fail such that we never have a
half written or corrupted recovered checkpoint.

Currently the abstract ShapeBuilder class serves too many different

to reduce the size and responsibilities, this PR moved all the
static factory methods used as a shortcut to create new shape builders
out to a new ShapeBuilders class, similar to how QueryBuilders is
used already.
With this commit the cluster health status changes are logged
on INFO level. The change is only logged on master and actively
triggered in AllocationService in order to minimize the impact of
constantly reevaluating ClusterState in a ClusterStateListener
although we know that no health-relevant change happened.
Closes#11657
In AbstractQueryTestCase we randomly add the `_name` property to
some of the queries. While this generally works, there are exceptional
cases where we assign the same name to two queries in the setup which
leads to test failures later. This PR adds an increasing counter value
to the base tests that gets appended to all random query names to
avoid this name clashes.
ClusterRebalanceAllocationDecider did not take unassigned shards into account

Currently the next delay is calculated based on System.currentTimeMillis() but the actual shards to delay based on the last time the GatewayAllocator tried to assign/delay the shard.
This introduces an inconsistency for the case where shards should have been delay-allocated between the GatewayAllocator-based timestamp and System.currentTimeMillis().

DateHistogramTests had some dependency on groovy scripts and

This commit changes TransportRequestOptions and TransportResponseOptions

This allows different circuit breakers to have different logging levels.
It's useful when diagnosing problems (say for instance with the

`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.

Some dependencies must be specified in a couple places in the build.
e.g. randomized runner is specified both in buildSrc (for the gradle

A user on the forum asked for what getIndexingCurrent is so I figured
i can just fix it in the code.

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.

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
dependent and might fail if we concurrently check if the shard is inactive
while the document we are indexing is in-flight.
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).
Closes#13132
This commit fixes a compilation issue due to modified type inference in
the latest JDK 9 early access builds. We just have to lend a helping
hand to type inference by being explicit about the type.

closes#14466
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.
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
gradle we now have a proper test framework artifact. This change moves
the classes used by the test framework into the test-framework module.

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.

The only way to refer to the plain highlighter is now `plain`, the only way to refer to the fast vector highlighter is `fvh` and the only way to refer to the postings highlighter is `postings`. The name variants like `highlighter`, `postings-highlighter` and `fast-vector-highlighter` have been removed.

This is not needed: full mvn verify passes.
Furthermore, there are all kinds of checks for this case
(rejected while shutting down) in the actual code, so there
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.
Some jenkins servers have this, but our codebase normalization doesn't
follow symlinks. Add this so that its correct.
Only really impacts tests, i suppose it helps if someone has a symlinked plugins/
but that is not recommended :)

properties like core syntax.

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
otherwise plugins can't access those extension points due to security restrictions.
This commit brings all the registration etc. from IndexCacheModule into
IndexModule. As a side-effect to remove a circular dependency between
IndicesService and IndicesWarmer this commit also cleans up IndicesWarmer and
separates the Engine from the warmer.
This changes how `min_score` is implemented both for `function_score` and the
search request parameter to confirm whether the minimum score is met in the
`matches()` phase of a TwoPhaseIterator.
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
the classes and calls the asEagerSingleton method on the multibinder. This does not actually
create a singleton. Instead we first bind the class as a singleton and add then add the class
to the multibinder.
Closes#14194
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.
