When specifying a time zone, RangeQueryBuilder currently throws an
exeption when the field does not use DateFieldMapper, but if there
are no mappers at all for that field it doesn't complain. To be
consistent we also throw expection now.
Refactors ExistsQueryBuilder and Parser, splitting the parse() method into a parsing
and a query building part. Also moving newFilter() utility method from parser to query builder.
Changes in the BaseQueryTestCase include introduction of randomized version to test disabled
FieldNamesFieldMappers and also getting rid of the need for createEmptyBuilder() method by
using registered prototype constants.
Relates to #10217Closes#11427
and a query building part, adding NamedWriteable implementation for serialization and hashCode(),
equals() for testing.
This change also adds tests using fixed set of leaf queries (Terms, Ids, MatchAll) as nested Queries in test query setup.
Also QueryParseContext is adapted to return QueryBuilder instances for inner filter parses instead of
previously returning Query instances, keeping old methods in place but deprecating them.

Today we provide the ability to plug in MergePolicy and
we provide the once lucene ships with. We do not recommend to change
the default and even only a small number of expert users would ever touch
this. This commit removes the ancient log byte size and log doc count
merge policy providers, simplifies the MergePolicy wiring and makes the
tiered MP the one and only default. All notions of a merge policy has been
removed from the docs and should be deprecated in the previous version.
Closes#11588
There used to be a null check for _field_names mapper not existing. This
was recently removed. However, there is a corner case when the mapper
may be missing: when no types or docs exist at all in the index.
This change adds back a null check and just returns no docs.
The current ExceptionsHelper.unwrapCause(exception) requires the incoming exception to support ElasticsearchWrapperException , which TranslogRecoveryPerformer.BatchOperationException doesn't implement. I opted for a more generic solution
We had to make CompressedXContent.equals decompress data to fix some
correctness issues which had the downside of making equals() slow. Now we store
a crc32 alongside compressed data which should help avoid decompress data in
most cases.

Now that mapping updates are sync and done before indexing we don't really need the waiting component. Also, removed many places were they were used as safe guard against delayed mapping updates, which are now not needed.
As part of the query refactoring, we want to be able to serialize queries by having them extend Writeable, rather than serializing their json. When reading them though, we need to be able to identify which query we have to create, based on its name.
For this purpose we introduce a new abstraction called NamedWriteable, which is supported by StreamOutput and StreamInput through writeNamedWriteable and readNamedWriteable methods. A new NamedWriteableRegistry is introduced also where named writeable prototypes need to be registered so that we are able to retrieve the proper instance of query given its name and then de-serialize it calling readFrom against it.
Closes#11553
While we had initially planned to keep rivers around in 2.0 to ease migration,
keeping support for rivers is challenging as it conflicts with other important
changes that we want to bring to 2.0 like synchronous dynamic mappings updates.
Nothing impossible to fix, but it would increase the complexity of how we
deal with dynamic mappings updates and manage rivers, while handling dynamic
mappings updates correctly is important for resiliency and rivers are on the go.
So removing rivers in 2.0 may well be a better trade-off.
These methods are now all in MappedFieldType. This removes the remaining
callers of the methods on FieldMapper, and cuts down the FieldMapper
API to no longer include them.
The MapperService is the "index wide view" of mappings. Methods on it
are used at query time to lookup how to query a field. This
change reduces the exposed api so that any information returned
is limited to that api exposed by MappedFieldType. In the future,
MappedFieldType will be guaranteed to be the same across all
document types for a given field.
Note CompletionFieldType needed some more settings moved to it. Other
than that, this change is almost purely cosmetic.
Split the parse method into a parsing and a query building part, adding serialization
and hashCode(), equals() for better testing. Add basic unit test for Builder and Parser.
Closes#11551
The shard can potentially not be deleted if the obsever that checks for the shard
STARTED is not registered because the registering is delayed by the disruption.
If the sum of delays is more than 10s then the wait for shard deletion will time out.
The ResourceWatcher used settings prefixed `watcher.`, which
potentially could clash with the watcher plugin.
In order to prevent confusion, the settings have been renamed to
`resource.reload` prefixes.
This also uses the deprecation logging infrastructure introduced
in #11033 to log deprecated settings and their alternative at
startup.
Closes#11175
In case a developer gets a list of ids from another data source,
it does not make a lot of sense, to convert it to an array first,
and then internally in IdsQueryBuilder elasticsearch creates a
list out of this.
Closes#5089
In order for exists queries to use the null value for
a field, null value needs to be part of the field type (should
differ between document types). This change moves null value
into the field type, as well as simplifies the null value
methods available to remove supportsNullValue().
#11363 introduced a retry logic for the case where we have to wait on a mapping update during the translog replay phase of recovery. The retry throws or recovery stats off as it may count ops twice.
There are different ways to register custom query parsers through plugins, a couple of them work per index via index settings, which is probably even too flexible. There also three different ways to add a global custom query parser through either IndicesQueriesModule or IndicesQueriesRegistry. This commit consolidates the registration of custom query parsers via IndicesQueriesModule#addQuery(Class<? extends QueryParser>). The complexity of supporting parsers per index is not needed hence it got removed. Also the other ways of registering global custom parsers are dropped in favour of the one mentioned above.
Closes#11481
The search template and template query did not run the template through the script engine before searching for an inner template. This meant that parsing for the inner template failed because the template was not always valid JSON (if it contained mustache code) when it was parsed to find the inner template. This has been fixed and Tests added to check for the failing behaviour.
Tests are from https://github.com/elastic/elasticsearch/pull/8393
In #10918, we introduced the prompt placeholders. These were had a different format
than our existing placeholders. This changes the prompt placeholders to follow the
format of the existing placeholders.

This commit adds an additioal jar that is shaded and keeps all the
artifacts that are used by default on the server-side unshaded. Users
that need a shaded jar can now use the `shaded` classifyer to pull
the shaded minimized jar in instead. Including the shaded jar in a
downstream project looks like this:
```XML
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<classifier>shaded</classifier>
</dependency>
```
After asynchronously fetching shard information the gateway allocator issues a reroute via a cluster state update task. #11421 introduced an optimization trying to avoid submitting unneeded reroutes when results for many shards come in together. This is done by having a rerouting flag, indicating a pending reroute is coming and thus any new incoming shard info doesn't need to issue a reroute. This flag wasn't reset upon an error in the reroute update task. Most notably - if a master node had to step during to a min_master_node violation, it could reject an ongoing reroute. Lacking to reset the flag causing it to skip any future reroute, when the node became master again.
Closes#11519
Since we are creating write.lock earlier now, blob store shouldn't attempt deleting this file during clean up at the end of the restore process. The file is locked and the blog store doesn't succeed, but it generates a lot of useless warnings "failed to delete file [write.lock] during snapshot cleanup".
Closes#11517
