Field names containing dots can cause problems. For example, @jpountz
made this recreation which cause no error, but can result in a
serialization exception if the type already exists:
https://gist.github.com/jpountz/8c66817e00a322b81f85
But this is not just a potential conflict. It also has larger problems,
since only the leaf mapper is created. The intermediate "foo" object
field would not exist if only "foo.bar" was in the mappings.
This change forbids the use of dots in field names. It also
fixes an issue with passing through the update_all_types setting,
which was always set to true whenever a type already existed (!).
I do not think we should worry about backwards compatibility here. This
should be a hard break (and added to the migration plugin).
This commit adds logic to prefer shards with higher priority
or from newer indicse to be allocated first if they are unallocated post API.
This commit allows users to set `index.priority` to a non-negative integer to
prioritize index recovery for certain indices. This setting is dynamically updateable
and defaults to `0`. If two indices have the same priority this change takes the creation
date into account to prioritize shards from newer indices which is important in the time-based
indices usecase.

When a bulk request fails on a Delete or Update request, the BulkItemResponse
reports incorrect "index" operation in the response. This PR fixes this
for the case of closed indices as reported in #9821 but also for
other failures and adds tests for the two cases covered.
Closes#9821
Moving the query building functionality from the parser to the builders
new toQuery() method analogous to other recent query refactorings.
Relates to #10217
the specialization can cause stack overflows if an exception is a
ElasticsearchWrapperException as well as a ElasticsearchException.
This commit just relies on the unwrap logic now to find the cause and only
renders if we the rendering exception is the cause otherwise forwards
to the generic exception rendering.
Closes#11994
While MappedFieldType contains settings for doc values and fielddata,
AbstractFieldMapper had special logic in its constructor that
required setting these on the field type from there. This change
removes those settings from the AbstractFieldMapper constructor.
As a result, defaultDocValues(), defaultFieldType() and
defaultFieldDataType() are no longer needed.
Currently parsing inner queries can return `null` which leads to unnecessary complicated
null checks further up the query hierarchy. By introducing a special EmptyQueryBuilder
that can be used to signal that this query clause should be ignored upstream where possible,
we can avoid additional null checks in parent query builders and still allow for this query
to be ignored when creating the lucene query later.
This new builder returns `null` when calling its `toQuery()` method, so at this point
we still need to handle it, but having an explicit object for the intermediate query
representation makes it easier to differentiate between cases where inner query clauses are
empty (legal) or are not set at all (illegal).
Also added check for empty inner builder list to BoolQueryBuilder and OrQueryBuilder.
Removed setters for positive/negatice query in favour of constructor with
mandatory non-null arguments in BoostingQueryBuilder.
Closes#11915
This commit merges the pre-existing special exception that
allowed to associate headers with exceptions and the elasticsaerch
base class `ElasticsearchException` This allows for more generic use
of exceptions where plugins can associate meta-data with any elasticsearch
base exception to control behavior etc.
This also addds a generic SecurityException to allow plugins to pass on
information based on the RestStatus.
If the version of a node is lower than the minimum supported version or higher than the maximum supported version, a node shouldn't be allowed to join and nodes should join that elected master node
Closes#11924
Removed ParseField#match variant that accepts the field name only, without parse flags. Such a method is harmful as it defaults to empty parse flags, meaning that no deprecation exceptions will be thrown in strict mode, which defeats the purpose of using ParseField. Unfortunately such a method was used in a lot of places were the parse flags weren't easily accessible (outside of query parsing), and in a lot of other places just by mistake.
Parse flags have been introduced now as part of SearchContext and mappers where needed. There are a few places (e.g. java api requests) where it is not possible to retrieve them as they depend on the index settings, in that case we explicitly pass in EMPTY_FLAGS for now, but this has to be seen as an exception.
Closes#11859
