This commit wraps the trace logging statements in
TransportBroadcastByNodeAction in trace enabled checks to avoid
unnecessarily allocating objects.
The most egregious offenders were the two trace logging statements in
BroadcastByNodeTransportRequestHandler#onShardOperation. Aside from the
usual object allocations that occur when invoking ESLogger#trace (the
allocated object array for the varargs Object... parameter), these two
logging statements were invoking ShardRouting#shortSummary generating a
bunch of char arrays and Strings (from the StringBuilder, and so a bunch
of array copies as well). In a scenario where there are a lot of shards
and this method is being invoked frequently (e.g., constantly hitting
the _stats endpoint), these two unprotected trace logging statements
were generating a lot of unnecessary allocations.
This commit modifies the handling of shard started cluster state updates
to use the general cluster state batching mechanism. An advantage of
this approach is we now get correct per-listener notification on
failures.
This commit removes a simple early-out check in
MetaDataMappingService#executeRefresh. The early-out is unnecessary
because the cluster state task execution framework will not invoke
ClusterStateTaskExecutor#execute if the list of tasks is empty.
This commit updates a stale Javadoc on
MetaDataMappingService#executeRefresh. Previously this method handled
refresh and update tasks. Update tasks have been removed and the method
was renamed, but the Javadoc was not updated to reflect this.
This is a relic from shading where it was trickier to implement.
Third party signatures are already in e.g. the test list, there
is no reason to separate them out.
Instead, we could have a third party signatures that does
something different... like keep tabs on third party libraries.
This is due to the fact that the query cache will still call the
onDocIdSetEviction callback in this case but with a number of entries equal to
zero.
Close#15043
This commit removes and now forbids all uses of the type-unsafe empty
Collections fields Collections#EMPTY_LIST, Collections#EMPTY_MAP, and
Collections#EMPTY_SET. The type-safe methods Collections#emptyList,
Collections#emptyMap, and Collections#emptySet should be used instead.
Today we try to have type-level granularity when dealing with mappings. This
does not play well with the cross-type validations that we are adding. For
instance we prevent the `_parent` field to point to an existing type. This
validation would be skipped today in the case of dedicated master nodes, since
those master nodes would only create the type that is being updated when
updating a mapping.
In 1.x it is possible via index templates to create an index with an alias with the same name as the index. The index name must match the index template and have an alias with the same name as the index being created.

Related to #15168
This change attempts to simplify the gradle tasks for precommit. One
major part of that is using a "less groovy style", as well as being more
consistent about how tasks are created and where they are configured. It
also allows the things creating the tasks to set up inter task
dependencies, instead of assuming them (ie decoupling from tasks
eleswhere in the build).
