The `lookupPrototype` method is not used anywhere. Seems like we rather use its `lookupProrotypeSafe` variant (which also throws exception if the prototype is not found) is always. This commit makes the safer variant the default one, by renaming it to "lookupPrototype" and removes the previous "unsafe" variant.
Today we call `writeByte` up to 3x per character in each string written via
`StreamOutput#writeString` this can have quite some overhead when strings
are long or many strings are written. This change adds a local buffer to
convert chars to bytes into the local buffer. Converted bytes are then
written via `writeBytes` instead reducing the overhead of this opertion.
Closes#21660
The overflows were happening in two places, the parsing of the template that
implicitly truncates the `order` when its value does not fall into the `integer`
range, and the comparator that sorts templates in ascending order, since it
returns `order2-order1`, which might overflow.
Closes#21622
* Fix highlighting on a stored keyword field
The highlighter converts stored keyword fields using toString().
Since the keyword fields are stored as utf8 bytes the conversion is broken.
This change uses BytesRef.utf8toString() to convert the field value in a valid string.
Fixes#21636
* Replace BytesRef#utf8ToString with MappedFieldType#valueForDisplay
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.

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.

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.

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.
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.

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.

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.

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.
Adds a version constant for it, bwc indices, and a vagrant upgrade-from
version. Also bumps the "upgrade from" version for the backwards-5.0
test and adds `skip`s for tests that don't fail against 5.0 so we skip
them during the backwards testing.
Finally, this skips the "Shrink index via API" test because it fails
consistently for me. Inconsistently for CI, but consistently for me.
I'll work on making it consistent tomorrow.
A previous commit added strict level parsing for the node stats API, but
that commit missed adding the same for the indices stats API. This

This changes only the query parsing behavior to be strict when searching on
boolean values. We continue to accept the variety of values during index time,
but searches will only be parsed using `"true"` or `"false"`.

When using TimeUnitRounding with a DAY_OF_MONTH unit, failing tests in #20833
uncovered an issue when the DST shift happenes just one hour after midnight
local time and sets back the clock to midnight, leading to an overlap.
Previously this would lead to two different rounding values, depending on
whether a date before or after the transition was rounded. This change detects
this special case and correct for it by using the previous rounding date for
both cases.
Closes#20833

#20960 removed `LocalDiscovery` and we now use `ZenDiscovery` in all our tests. To keep cluster forming fast, we are using a `MockZenPing` implementation which uses static maps to return instant results making master election fast. Currently, we don't set `minimum_master_nodes` causing the occasional split brain when starting multiple nodes concurrently and their pinging is so fast that it misses the fact that one of the node has elected it self master. To solve this, `InternalTestCluster` is modified to behave like a true cluster and manage and set `minimum_master_nodes` correctly with every change to the number of nodes.
Tests that want to manage the settings themselves can opt out using a new `autoMinMasterNodes` parameter to the `ClusterScope` annotation.
Having `min_master_nodes` set means the started node may need to wait for other nodes to be started as well. To combat this, we set `discovery.initial_state_timeout` to `0` and wait for the cluster to form once all node have been started. Also, because a node may wait and ping while other nodes are started, `MockZenPing` is adapted to wait rather than busy-ping.
When processing a mapping updates, the master current creates an `IndexService` and uses its mapper service to do the hard work. However, if the master is also a data node and it already has an instance of `IndexService`, we currently reuse the the `MapperService` of that instance. Sadly, since mapping updates are change the in memory objects, this means that a mapping change that can rejected later on during cluster state publishing will leave a side effect on the index in question, bypassing the cluster state safety mechanism.
This commit removes this optimization and replaces the `IndexService` creation with a direct creation of a `MapperService`.
Also, this fixes an issue multiple from multiple shards for the same field caused unneeded cluster state publishing as the current code always created a new cluster state.

This changes adds a test discovery (which internally uses the existing
mock zenping by default). Having the mock the test framework selects be a discovery
greatly simplifies discovery setup (no more weird callback to a Node
method).
Today when a node starts, we create dynamic socket permissions based on
the configured HTTP ports and transport ports. If no ports are
configured, we use the default port ranges. When a tribe node starts, a
tribe node creates an internal node client for connecting to each remote
cluster. If neither an explicit HTTP port nor transport ports were
specified, the default port ranges are large enough for the tribe node
and its internal node clients. If an explicit HTTP port or transport
port was specified for the tribe node, then socket permissions for those
ports will be created, but not for the internal node clients. Whether
the internal node clients have explicit ports specified, or attempt to
bind within the default range, socket permissions for these will not
have been created and the internal node clients will hit a permissions
issue when attempting to bind. This commit addresses this issue by also
accounting for tribe nodes when creating the dynamic socket
permissions. Additionally, we add our first real integration test for
tribe nodes.

This commit adds an assertion to ensure that we do not introduce blocking calls in code
