If the node name is explicitly set it's not derived from the node ID
meaning that it doesn't immediately appear in the logs. While it can be
tracked down in other places, it would be easier for info purposes if it
just showed up explicitly. This commit adds the node ID to the logs,
whether or not the node name is set.

Implements a null coalescing operator in painless that looks like `?:`. This form was chosen to emulate Groovy's `?:` operator. It is different in that it only coalesces null values, instead of Groovy's `?:` operator which coalesces all falsy values. I believe that makes it the same as Kotlin's `?:` operator. In other languages this operator looks like `??` (C#) and `COALESCE` (SQL) and `:-` (bash).
This operator is lazy, meaning the right hand side is only evaluated at all if the left hand side is null.
Plugins are closed if they implement java.io.Closeable but this is not
clear from the plugin interface. This commit clarifies this by declaring
that Plugins implement java.io.Closeable and adding an empty
implementation to the base Plugin class.

By default, it is recommended to start bulk with a size of 10-15MB, and increase it gradually to get the right size for the environment. The example shows originally 1GB, which can lead to some users to just copy-paste the code snippet and start with excessively big sizes.
Backport of #21664 in master branch.
AbstractScopedSettings has the ability to only apply updates/deletes
to dynamic settings. The flag is currently not respected when a setting
is reset/deleted which causes static node settings to be reset if a non-dynamic
key is reset via `null` value.
Closes#21593
This commit moves several allocation decider related inner classes
into their own top-level class, in order to use more easily in
the allocation explain API. This commit also renames some of those
decision related classes to more suitable names.
This is simply a cosmetic change - no functionality changes with this
commit whatsoever.
To summarize the changes:
1. ShardAllocationDecision renamed to AllocateUnassignedDecision
2. RelocationDecision moved to a top-level class
3. MoveDecision moved to a top-level class
4. RebalanceDecision moved to a top-level class
5. ShardAllocationDecisionTests renamed to AllocateUnassignedDecisionTests
6. NodeRebalanceResult moved to a top-level class
7. ShardAllocationDecision#WeightedDecision moved to a top-level class and renamed to NodeAllocationResult.
The "test" task can complete its execution with a timeout exception before the "block-task" actually starts executing. The test thus has to wait for both to be
completed before checking that the updateTasksPerExecutor map has been properly cleaned up.
The first changed referred to an example of the 2.4 documentation. I removed the no longer relevant parts. We should consider adding a little more here.
The second change was just then->than in the suggest_mode popular section
According to the docs and our own tests we accept an ids query without specified
types and default to all types in the index mapping in this case. This changes
the builder to reflect this by making the types no longer a required constructor
argument and changes the parser to reflect that.
A first step moving away from the current parsing to use the generalized
Objectparser and ConstructingObjectParser. This PR start by making use of it in
MatchAllQueryBuilder and IdsQueryBuilder.
* Fix compilation in Eclipse
I'm not sure what the bug is, but ecj doesn't like this expression
unless the type is set explicitly.
* Add comment explaining why no diamond operator
This commit exposes the executor service interface from thread
pool. This will enable some high-level concurrency primitives that will
make some code cleaner and simpler.

We kept `netty_3` as a fallback in the 5.x series but now that master
is 6.0 we don't need this or in other words all issues coming up with
netty 4 will be blockers for 6.0.
Our default pattern layout truncates log messages. This is to avoid
blowing disk space from excessively log messages, which can happen if a
message contains a mapping or an large query. Yet, we trunacte from the
beginning which is probably where the most germane information is. This
commit modifies the default pattern layout to trunacte from the end.

The tests rely on the allocation decider allowing allocation and
the disk threshold decider wasn't allowing it. This came up from
time to in CI but *all* the time on my local machine because it is
a small ssd.
The default search timeout is not respected because the timeout is
unconditionally set from the query. This commit fixes this issue, and
adds a test that the default search timeout is correctly attached to the
search context.

There is not yet a BWC layer in sequence numbers. This commit sets the
BWC version to 6.0.0 for the BWC and rolling upgrade tests until this
BWC layer is built.
There is an issue in the Grok Processor, where trace_match: true does not inject the _ingest._grok_match_index into the ingest-document when there is just one pattern provided. This is due to an optimization in the regex construction. This commit adds a check for when this is the case, and injects a static index value of "0", since there is only one pattern matched (at the first index into the patterns).
To make this clearer, more documentation was added to the grok-processor docs.
Fixes#21371.
This change fixes the rnage query so that an exception is always thrown if the range query uses epoch time together with a time zone. Since epoch time is always UTC it should not be used with a time zone.
Closes#21501
There have been reports that the query cache did not manage to speed up search
requests when the query includes a large number of different sub queries since
a single request may manage to exhaust the whole history (256 queries) while
the query cache only starts caching queries once they appear multiple times in
the history (#16031). On the other hand, increasing the size of the query cache
is a bit controversial (#20116) so this pull request proposes a different
approach that consists of never caching term queries, and not adding them to the
history of queries either. The reasoning is that these queries should be fast
anyway, regardless of caching, so taking them out of the equation should not
cause any slow down. On the other hand, the fact that they are not added to the
cache history anymore means that other queries have greater chances of being
cached.
