Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN)
functions which are in the family of CONDITIONAL functions.
Implementation follows PostgreSQL behaviour, so the functions return
`NULL` when all of their arguments evaluate to `NULL`.
Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and
`ConditionalProcessor` respectively, to be able to reuse them for
`Greatest` and `Least` evaluations. To achieve that `ConditionalOperation`
has been added to differentiate between the functionalities at execution
time.
Closes: #35878
Due to some unresolvable type conflict between the expected definition
in JDBC vs ODBC, the driver mode is now passed over so that certain
command can change their results accordingly (in this case SYS COLUMNS)
Fix#35376
This operator handles nulls in different way than the normal `=`.
If one of the operants is `null` and the other not it returns `false`.
If both operants are `null` it returns `true`. Therefore in contrary to
`=`, which returns `null` if at least one of the operants is `null`, this one
never returns `null` as a result.
Closes: #35871
Code that operates on-top of the engine requires all readers returned to be
unwrapped into ElasticsearchDirectoryReader. The special reader
the FrozenEngine uses wasn't wrapped.
We didn't check that the ExplainLifecycleRequest was constructed with at least
one index before, now that we do we must also make sure the tests
mutateInstance() method used in equals/hashCode checks doesn't accidentally
create an empty index array.
Closes#35822
When there is no persistent tasks metadata we could hit a null pointer
exception when executing a follower stats request. This is because we
inspect the persistent tasks metadata. Yet, if no tasks have been
registered, this is null (as opposed to empty). We need to avoid
de-referencing the persistent tasks metadata in this case. That is what
this commit does, and we add a test for this situation.
By setting the cron to 2017, we ensure it won't trigger. This makes it
easier to test because we know the job will _only_ be in STARTED,
and we can ignore INDEXING states due to transient triggers.
Closes#35779
Move away from performing eager, fail-fast validation of mismatched
mapping to a lazy evaluation based on the fields actually used in the
query. This allows queries to run on the parts of the indices that
"work" which is not just convenient but also a necessity for large
mappings (like logging) where alignment is hard/impossible to achieve.
Fix#35659
Creates the manage_token cluster privilege and adds it to the
kibana_system role. This is required if kibana were to use the token
service for its authenticator process.
Because kibana_system already has manage_saml this effectively
only adds the privilege to create tokens.
Introduce INTERVAL as a DataType
Add INTERVAL to the grammar which supports the standard SQL declaration
(without precision):
> INTERVAL '1 23:45:01.123456789' DAY TO SECOND
but also number for single unit intervals:
> INTERVAL 1 YEAR
as well as the plurals of the units:
> INTERVAL 2 YEARS
Interval are internally supported as just another Literal being backed
by java.time.Period and java.time.Duration
Move JDBC away from JDBCType enum to SQLType interface
Refactor DataType by moving it into server core and adding dedicated (and
much simpler) JDBC driver type
Improve internal JDBC conversion by normalizing on the DataType
Rename JDBC columnInfo to JdbcColumnInfo to differentiate between it and
the SQL ColumnInfo
Fix#29990
This commit removes the parsing code from the PutLicenseResponse server variant, and the toXContent portion from the corresponding client variant.
Relates to #35547
This commit removes the parsing code from the PostStartBasicResponse server variant. It also makes the server response implement StatusToXContent which allows us to save a couple of lines of code in the corredponding REST action.
Relates to #35547
The RestHasPrivilegesAction previously handled its own XContent
generation. This change moves that into HasPrivilegesResponse and
makes the response implement ToXContent.
This allows HasPrivilegesResponseTests to be used to test
compatibility between HLRC and X-Pack internals.
A serialization bug (cluster privs) was also fixed here.
* The port assigned to all loopback interfaces doesn't necessarily have to be the same for ipv4 and ipv6
=> use actual address from profile instead of just port + loopback in test
* Closes#35584
This parameter in the `query_string` query was deprecated in 6.0 and ignored
since then. Its API methods and remaining uses can be removed in the upcoming
major version.
Relates to #35734
This commit adds a rest endpoint for freezing and unfreezing an index.
Among other cleanups mainly fixing an issue accessing package private APIs
from a plugin that got caught by integration tests this change also adds
documentation for frozen indices.
Note: frozen indices are marked as `beta` and available as a basic feature.
Relates to #34352
Currently there is a common NPE in the IndexFollowingIT that does not
indicate the test failing. This is when a cluster state listener is
called and certain index metadata is not yet available.
This commit checks that the metadata is not null before performing the
logic that depends on the metadata.

Fix bug in Analyzer that caused it to report unsupported fields only
when declared in projections. The rule has been extended to all field
declarations.
Fix#35673
RolloverStep previously had a name of "attempt_rollover", which was
inconsistent with all other step names due it its use of an underscore
instead of a dash.
This commit switches from using java util's default timezone method to
using joda. The former can cause problems when the string representation
of the timezone is unknown to joda.
closes#35518
Removed extending of AbstractComponent and changed logger usage to
explicit declaration. Abstract classes still have logger
declaration using this.getClass() in order to show implementation class
name in its logs.
See #34488
RolloverAction will now periodically check the rollover conditions using
the Rollover API with the dry_run option as an AsyncWaitStep, then run
the rollover itself by calling the Rollover API with no conditions,
which will always roll over, as an AsyncActionStep. This will resolve
race condition issues in policies using RolloverAction.

In the event that the target index does not exist when `CopyExecutionStateStep`
executes, this avoids a `NullPointerException` and provides a more helpful error
to the ILM user.
Resolves#35567
Kibana now uses the tasks API to manage automatic reindexing of the
.kibana index during upgrades.
The implementation of the tasks API requires that
1. the user executing the task can create & write to the ".tasks" index
2. the user checking on the status of the task can read (Get) the
relevant document from the ".tasks" index
