Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
Sometimes, in some places, the clocks are set back across midnight, leading to
overlapping days. This was not handled as expected, and this change fixes this.
Additionally, in this situation it is not true that rounding a time down to the
nearest day is a monotonic operation, as asserted in these tests. This change
suppresses those assertions in those rare cases.
Fixes#27966.
The `terms` query is really designed for filtering and highlighting it might
cause performance issues if it wraps many terms, so I am documenting
highlighting these queries as a best-effort only.
Closes#28099
This change removes the InternalClient and the InternalSecurityClient. These are replaced with
usage of the ThreadContext and a transient value, `action.origin`, to indicate which component the
request came from. The security code has been updated to look for this value and ensure the
request is executed as the proper user. This work comes from #2808 where @s1monw suggested
that we do this.
While working on this, I came across index template registries and rather than updating them to use
the new method, I replaced the ML one with the template upgrade framework so that we could
remove this template registry. The watcher template registry is still needed as the template must be
updated for rolling upgrades to work (see #2950).
* Moves more classes over to ToXContentObject/Fragment
* Removes ToXContentToBytes
* Removes ToXContent from Enums
* review comment fix
* slight change to use XContantHelper
These members are default initialized on contruction and then set by the
init() method. It's possible that another thread accessing the object
after init() is called could still see the null/0 values, depending on how
the compiler optimizes the code.
This is the x-pack side of the removal of `accumulateExceptions()` for both `TransportNodesAction` and `TransportTasksAction`.
There are occasional, random failures that occur during API calls that are silently ignored from the caller's perspective, which also leads to weird API responses that have no response and also no errors, which is obviously untrue.
With the leniency in Version.java we missed to really setup BWC
testing for static indices. This change brings back the testing and adds
missing bwc indices.

Persistent tasks should verify that completion notification is done for correct version of the task, otherwise a delayed notification from an old node can accidentally close a newly reassigned task.
PersistentTasksCustomMetadata was using a generic param named `Params`. This conflicted with the imported interface `ToXContent.Params`. The java compiler was preferring the generic param over the interface so everything was fine but Eclipse apparently prefers the interface int his case which was screwing up the Hierarchy and causing compile errors in Eclipse. This changes fixes it by renaming the Generic param to `P`
Removes the last pieces of ActionRequest from PersistentTaskRequest and renames it into PersistTaskParams, which is now just an interface that extends NamedWriteable and ToXContent.
This commit is response to the renaming of the random ASCII helper
methods in ESTestCase. The name of this method was changed because these
methods only produce random strings generated from [a-zA-Z], not from
all ASCII characters.
Add a check for the current state waitForPersistentTaskStatus before waiting for the next one. This fixes sporadic failure in testPersistentActionStatusUpdate test.
Fixes#928
Refactors NodePersistentTask and RunningPersistentTask into a single AllocatedPersistentTask. Makes it possible to update Persistent Task Status via AllocatedPersistentTask.
If a persistent task throws an exception, the persistent tasks framework will no longer try to restart the task. This is a temporary measure to prevent threshing the cluster with endless restart attempt. We will revisit this in the future version to make the restart process more robust. Please note, however, that if node executing the task goes down, the task will still be restarted on another node.
Removes the transport layer dependency from PersistentActions, makes PersistentActionRegistry immutable and rename actions into tasks in class and variable names.
Refactors xcontent serialization of Request and Status to use their writable names instead of action name. That simplifies the parsing logic, allows reuse of the same status object for multiple actions and is consistent with how named objects in xcontent are used.
