Before this change Eclipse (4.6.1) would show compile errors in `ClusterRerouteRequestTests` for the elements in `RANDOM_COMMAND_GENERATORS`. This seems to be because the eclipse compiler does not recognised that the elements in the list are all `Supplier`s of bjects that are subclasses of `AllocationCommand`.
This change fixes the problem by adding a generics hint to the `Arrays.toList()` call.
All plugins currently have their own licenses dir for the
dependencyLicenses task, but core disables this and has the check inside
distribution. This may have been better for maven, but for
gradle it makes more sense to just use the dependencyLicenses task that
automatically exists inside :core, and remove the hacked up version that
is inside distribution.
This commit changes the Javadocs in OsProbe.java to take advantage of
the fact that the line-length limit is 140 characters. This change makes
these Javadocs easier to read and easier to maintain.
This commit removes JVMCheck. Previously there were three checks in this
class:
- check for super word bug in JDK 7
- check for G1GC bugs in JDK 8
- check for broken IBM JDKs
The first check is obsolete since we require JDK 8 now. The second check
is refactored into a bootstrap check. The third check is removed since
we do not even support the IBM JDK.

Before, when requesting to get the snapshots in a repository, if `_all` was
specified for the set of snapshots to get, any in-progress snapshots would
be returned twice. This commit fixes the issue ensuring that each snapshot,
whether in-progress or completed, is only returned once when making a call to
get snapshots (GET /_snapshot/{repository_name}/_all).
This commit also enables `_current` to appear anywhere in
the get snapshots list, and will be used as a pseudo regex to
mean "match any currently running snapshots".
Closes#21335
Today when acquiring load average stats, this method is rather lenient
when reading /proc/loadavg. This commit removes this leniency so that
any such issues are more likely to be exposed to the end-user.

Adds support for `?slices=N` to reindex which automatically
parallelizes the process using parallel scrolls on `_uid`. Performance
testing sees a 3x performance improvement for simple docs
on decent hardware, maybe 30% performance improvement
for more complex docs. Still compelling, especially because
clusters should be able to get closer to the 3x than the 30%
number.
Closes#20624
Today when writing an unbounded queue_size in the cat thread pool API,
we write null. This commit modifies this so that the output is -1 so
that the output is always present, and always a numeric value.

Exist requests are supposed to never throw an exception, but rather return true or false depending on whether some resource exists or not. Indices exists does that for indices and accepts wildcard expressions too. The way the api works internally is by resolving indices and catching IndexNotFoundException: if an exception is thrown the index does not exist hence it returns false, otherwise it returns true. That works ok only if ignore_unavailable and allow_no_indices indices options are both set to false, meaning that they are strict and any missing index or wildcard expressions that resolves to no indices will lead to an exception that can be thrown and cause false to be returned.
Unfortunately the indices options have been configurable up until now for this request, meaning that one can set ignore_unavailable or allow_no_indices to true and have the indices exist request return true for indices that really don't exist, which makes very little sense in the context of this api.
This commit removes the indicesOptions setter from the IndicesExistsRequest and makes settable only expandWildcardsOpen and expandWildcardsClosed, hence a subset of the available indices options. This way we can guarantee more consistent behaviour of the indices exists api. We can then remove the ignore_unavailable and allow_no_indices option from indices exists api spec
Today if you start Elasticsearch with the status logger configured to
the warn level, or use a transport client with the default status logger
level, you will see warn messages about deprecation loggers being
created with different message factories and that formatting might be
broken. This happens because the deprecation logger is constructed using
the message factory from its parent, an artifact leftover from the first
Log4j 2 implementation that used a custom message factory. When that
custom message factory was removed, this constructor invocation should
have been changed to not explicitly use the message factory from the
parent. This commit fixes this invocation. However, we also had some
status checking to all tests to ensure that there are no warn status log
messages that might indicate a configuration problem with Log4j 2. These
assertions blow up badly without the fix for the deprecation logger
construction, and also caught a misconfiguration in one of the logging
tests.

Today we validate the target index name late and therefore don't fail for instance
if the target index already exists and `dry_run=true` was specified. This change
validates the index name before we early terminate if dry_run is set.
Closes#21149
Today we still have a leftover from older percolators where lucene
query instances where created ahead of time and rewritten later.
This `LateParsingQuery` was resolving `now()` when it's really used which we
don't need anymore. As a side-effect this failed to execute some highlighting
queries when they get rewritten since at that point `now` access it not permitted
anymore to prevent bugs when queries get cached.
Closes#21295
This commit introduces a new execution mode for the query_string query, which
is intended down the road to be a replacement for the current _all field.
It now does auto-field-expansion and auto-leniency when the following criteria
are ALL met:
The _all field is disabled
No default_field has been set in the index settings
No default_field has been set in the request
No fields are specified in the request
Additionally, a user can force the "all-like" execution by setting the
all_fields parameter to true.
When executing in all field mode, the query_string query will look at all the
fields in the mapping that are not metafields and can be searched, and
automatically expand the list of fields that are going to be queried.

According to ISO 8601, a time zone offset of zero, can be stated numerically as
"+00:00", "+0000", or "00". The Joda library also seems to allow for "-00:00",
"-00" and "-0000". This adds some test to the DateMathParserTests that check
that we also conform to this.
Closes#21320
The usage information for `elasticsearch-plugin` is quiet verbose and makes the
actual error message that is shown when trying to remove an non-existing plugin
hard to spot. This changes the error code to not trigger printing the usage
information.
Closes#21250
ShardInfo#toString resorts to calling ShardInfo#toXContent via
Strings#toString. However, the resulting XContent object will not start
with an object, and this is a violation of the generator state
machine. This commit fixes this issue by replacing the override of
toString to provide simple non-toXContent output of the ShardInfo
instance. Without this fix, ShardInfo#toString will instead produce
"Error building toString out of XContent:
com.fasterxml.jackson.core.JsonGenerationException: Can not write a
field name, expecting a value"

Our test infrastructure checks after running each test that there are no more in-flight requests on the shard level. Whenever the check fails, we only know that there were in-flight requests but don't know what requests were causing this issue. This commit adds the replication tasks that are still active at that moment to the assertion error.
With #21099 we removed support for the ignored allow_no_indices parameter in indices upgrade API. Truth is that ignore_unavailable and expand_wildcards were also ignored, in indices upgrade as well as upgrade status API. Those parameters are though supported internally and settable through java API, hence they should be all supported on the REST layer too.
`FilterAggregationBuilder` today misses to rewrite queries which causes failures
if a query that uses a client for instance to lookup terms since it must be rewritten first.
This change also ensures that if a client is used from the rewrite context we mark the query as
non-cacheable.
Closes#21301
Plugins: Remove pluggability of ZenPing
ZenPing is the part of zen discovery which knows how to ping nodes.
There is only one alternative implementation, which is just for testing.
This change removes the ability to add custom zen pings, and instead
hooks in the MockZenPing for tests through an overridden method in
MockNode. This also folds in the ZenPingService (which was really just a
single method) into ZenDiscovery, and removes the idea of having
multiple ZenPing instances. Finally, this was the last usage of the
ExtensionPoint classes, so that is also removed here.
Since we now validate all consumed request parameter, users can't specify
`_cat/nodes?full_id=true|false` anymore since this parameter is consumed late.
This commit adds a test for this parameter and consumes it before request is processed.
Closes#21266
This would allow MapperService to still be usable in contexts when a
QueryShardContext cannot be obtained, for instance in the case that a
MapperService needs to be created only to merge mappings.
Currently the request cache adds a `CacheEntity` object. It looks quite innocent
but in practice it has a reference to a lambda that knows how to create a value.
The issue is that this lambda has implicit references to the SearchContext
object, which can be quite heavy since it holds a structured representation of
aggregations for instance.
This pull request splits the `CacheEntity` object from the object that generates
cache values.
Stored scripts and ingest node configuration are important parts of the overall cluster state and should be included into a snapshot together with index templates and persistent settings if the includeGlobalState is set to true.
Closes#21184
These tests had a single method due to the fact that es didn't support resetting settings when they were first written. They can now be rewritten to have separate methods and an after method that resets the setting that is left behind.
This adds checks for expected warning headers to the query builder test
infrastructure. Tests that are adding deprecation warnings to the response
headers need to check those, otherwise the abstract base class for the test
class will complain at teardown.
This query is deprecated from 5.0 on. Similar to IndicesQueryBuilder we should
log a deprecation warning whenever this query is used.

The pending cluster state queue is used to hold incoming cluster states from the master. Currently the elected master doesn't publish to itself as thus the queue is not used. Sometimes, depending on the timing of disruptions, a pending cluster state can be put on the queue (but not committed) but another master before being isolated. If this happens concurrently with a master election the elected master can have a pending cluster state in its queue. This is not really a problem but it does confuse our assertions during tests as we check to see everything was processed correctly.
This commit takes a temporary step to clear (and fail) any pending cluster state on the master after it has successfully published a CS. Most notably this will happen when the master publishes the cluster state indicating it has just become the master.
Long term we are working to change the publishing mechanism to make the master use the pending queue just like other nodes, which will make this a non issue.
See https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+java9-periodic/509 for example.
Lucene 6.2 introduces the new `Analyzer.normalize` API, which allows to apply
only character-level normalization such as lowercasing or accent folding, which
is exactly what is needed to process queries that operate on partial terms such
as `prefix`, `wildcard` or `fuzzy` queries. As a consequence, the
`lowercase_expanded_terms` option is not necessary anymore. Furthermore, the
`locale` option was only needed in order to know how to perform the lowercasing,
so this one can be removed as well.
Closes#9978
Since we have the ingest node type, there is either IngestActionFilter or IngestProxyActionFilter registered, depending on whether the node is an ingest node or not. The special case that shortcuts the execution in case there are no filters is never exercised.
This change adds an option called `split_on_whitespace` which prevents the query parser to split free text part on whitespace prior to analysis. Instead the queryparser would parse around only real 'operators'. Default to true.
For instance the query `"foo bar"` would let the analyzer of the targeted field decide how the tokens should be splitted.
Some options are missing in this change but I'd like to add them in a follow up PR in order to be able to simplify the backport in 5.x. The missing options (changes) are:
* A `type` option which similarly to the `multi_match` query defines how the free text should be parsed when multi fields are defined.
* Simple range query with additional tokens like ">100 50" are broken when `split_on_whitespace` is set to false. It should be possible to preserve this syntax and make the parser aware of this special syntax even when `split_on_whitespace` is set to false.
* Since all this options would make the `query_string_query` very similar to a match (multi_match) query we should be able to share the code that produce the final Lucene query.
The `IndexService#newQueryShardContext()` method creates a QueryShardContext on
shard `0`, with a `null` reader and that uses `System.currentTimeMillis()` to
resolve `now`. This may hide bugs, since the shard id is sometimes used for
query parsing (it is used to salt random score generation in `function_score`),
passing a `null` reader disables query rewriting and for some use-cases, it is
simply not ok to rely on the current timestamp (eg. percolation). So this pull
request removes this method and instead requires that all call sites provide
these parameters explicitly.
