The code was testing `PointRangeQuery` however we now use the
`IndexOrDocValuesQuery` in field mappers. This makes the test generate queries
through mappers so that we test the actual queries that would be generated.
This commit changes the build hash to be the string "Unknown" when for
some reason this build hash is not available. This aligns the value with
the value we use when the hash is not available from the jar
manifest. This situation can occur when running tests from a worktree
which is not currently handled correctly by JGit, the upstream
dependency that is used to acquire the hash. This causes problems when
running tests locally because the warning header pattern expects a hash
or the string "Unknown". While the warning header pattern be changed to
allow "N/A" as well, it seemed more sensible to align the value here
with the value when the hash is not available from the jar manifest.

Two tests were periodically failing. What both tests are doing is starting a relocation of a shard from one node to another. Once the
recovery process is started, the test blocks cluster state processing on the relocation target using the BlockClusterStateProcessing disruption. The test then indefinitely
waits for the relocation to complete. The stack dump shows that the relocation is stuck in the PeerRecoveryTargetService.waitForClusterState method, waiting for the relocation target node to have at least the same cluster state
version as the relocation source.
The reason why it gets stuck is the following race:
1) The test code executes a reroute command that relocates a shard from one node to another
2) Relocation target node starts applying the clusterstate with relocation info, starting the recovery process.
4) Recovery is super fast and quickly goes to the waitForClusterState method, which wants to ensure that the cluster state that is
applied on the relocation target is at least as new as the one on the relocation source. The relocation source has already applied the
cluster state but the relocation target is still in the process of applying it. The waitForClusterState method thus uses a
ClusterObserver to wait for the next cluster state. Internally this means submitting a task with priority HIGH to the cluster service.
5) Cluster state application is about to finish on the relocation target. As one of the last steps, it acks to the master which makes the
reroute command return successfully.
6) The test code then blocks cluster state processing on the relocation target by submitting a cluster state update task (with priority
IMMEDIATE) that blocks execution.
If the task that is submitted in step 6 is handled before the one in step 4 by ClusterService's thread executor, cluster state
processing becomes blocked and prevents the cluster state observer from observing the applied cluster state.
This refactors the `TransportShardBulkAction` to split it appart and make it
unit-testable, and then it also adds unit tests that use these methods.
In particular, this makes `executeBulkItemRequest` shorter and more readable
This commit fixes the date format in warning headers. There is some
confusion around whether or not RFC 1123 requires two-digit
days. However, the warning header specification very clearly relies on a
format that requires two-digit days. This commit removes the usage of
RFC 1123 date/time format from Java 8, which allows for one-digit days,
in favor of a format that forces two-digit days (it's otherwise
identical to RFC 1123 format, it is just fixed width).

This commit adds a convenience method for simultaneously asserting
settings deprecations and other warnings and fixes some tests where
setting deprecations and general warnings were present.
We have many version constants in master that have already been
released, but are still marked (by naming convention) as unreleased.
This commit renames those version constants.
Previously, cluster.routing.allocation.same_shard.host was not a dynamic
setting and could not be updated after startup. This commit changes the
behavior to allow the setting to be dynamically updatable. The
documentation already states that the setting is dynamic so no
documentation changes are required.
Closes#22992
When multiple reduce phases were needed the per term error got lost in subsequent reduces in some situations:
When a previous reduce phase had calculated a non-zero error for a particular bucket we were not accounting for this error in subsequent reduce phases and instead were relying on the overall error for the agg which meant we were implicitly assuming that all shards that made up that aggregation had returned the term. This is plainly not true so we need to make sure the per term error for the aggregation is used when calcualting the error for that term in the new reduced aggregation.
Change Setting#get(Settings, Settings) to fallback only if the setting is present in the secondary.
This is needed to fix setting that relies on other settings.
Replace IT with uts.
The current implementation of RestClient.performAsync() methods can throw exceptions before the request is asynchronously executed. Since it only throws unchecked exceptions, it's easy for the user/dev to forget to catch them. Instead I think async methods should never throw exceptions and should always call the listener onFailure() method.
This change adds a new test task, platformTest, which runs `gradle test
integTest` within a vagrant host. This will allow us to still test on
all the supported platforms, but be able to standardize on the tools
provided in the host system, for example, with a modern version of git
that can allow #22946.
In order to have sufficient memory and cpu to run the tests, the
vagrantfile has been updated to use 8GB and 4 cpus by default. This can
be customized with the `VAGRANT_MEMORY` and `VAGRANT_CPUS` environment
variables. Also, to save time to show this can work, it currently uses
the same Vagrantfile the packaging tests do. There are a lot of cleanups
we can do to how the gradle-vagrant tasks work, including generating
Vagrantfile altogether, but I think this is fine for now as the same
machines that would run platformTest run packagingTest, and they are
relatively beefy machines, so the higher memory and cpu for them, with
either task, should not be an issue.
The warning header used by Elasticsearch for delivering deprecation
warnings has a specific format (RFC 7234, section 5.5). The format
specifies that the warning header should be of the form
warn-code warn-agent warn-text [warn-date]
Here, the warn-code is a three-digit code which communicates various
meanings. The warn-agent is a string used to identify the source of the
warning (either a host:port combination, or some other identifier). The
warn-text is quoted string which conveys the semantic meaning of the
warning. The warn-date is an optional quoted date that can be in a few
different formats.
This commit corrects the warning header within Elasticsearch to follow
this specification. We use the warn-code 299 which means a
"miscellaneous persistent warning." For the warn-agent, we use the
version of Elasticsearch that produced the warning. The warn-text is
unchanged from what we deliver today, but is wrapped in quotes as
specified (this is important as a problem that exists today is that
multiple warnings can not be split by comma to obtain the individual
warnings as the warnings might themselves contain commas). For the
warn-date, we use the RFC 1123 format.

We recently added parsing code to parse suggesters responses into java api objects. This was done using a switch based on the type of the returned suggestion. We can now replace the switch with using NamedXContentRegistry, which will also be used for aggs parsing.
Previously when multiple reduces occured for the terms aggregation we would add up the errors for the aggregations but would not take into account the errors that had already been calculated for the previous reduce phases.
This change corrects that by adding the previously created errors to the new error value.
