For the response parsing we want to be lenient when it comes to parsing
new xContent fields. In order to ensure this in our testing, this change
adds a utility method to XContentTestUtils that takes xContent bytes
representation as input and recursively a random field on each object
level.
Sometimes we also want to exclude a whole subtree from this treatment
(e.g. skipping "_source"), other times an element (e.g. "fields", "highlight"
in SearchHit) can have arbitraryly named objects. Those cases can be
specified as exceptions.
This commit removes wrapper methods on QueryShardContext used to compile
scripts. Instead, the script service is made accessible in the context,
and calls to compile can be made directly. This will ease transition to
each of those location becoming their own context, since they would no
longer be able to expect the same script class type.
Splits TranslogRecoveryPerformer into three parts:
- the translog operation to engine operation converter
- the operation perfomer (that indexes the operation into the engine)
- the translog statistics (for which there is already RecoveryState.Translog)
This makes it possible for peer recovery to use the same IndexShard interface as bulk shard requests (i.e. Engine operations instead of Translog operations). It also pushes the "fail on bad mapping" logic outside of IndexShard. Future pull requests could unify the BulkShard and peer recovery path even more.
The unified highlighter rewrites MultiPhrasePrefixQuery to SpanNearQuer even when there is a single term in the phrase.
Though SpanNearQuery throws an exception when the number of clauses is less than 2.
This change returns a simple PrefixQuery when there is a single term and builds the SpanNearQuery otherwise.

Pins the random testing seed at build start rather than letting
it vary with every randomized testing invocation. This is useful
for projects where random decisions in one randomized testing run
can effect the outcome of a second randomized testing run such as
the full cluster restart tests.
The goal isn't for tests to be able to assume that random decision
will be the same in both tests. It is more to make sure that the
seed printed when a test fails reproduces the appropriate random
decisions. And pinning the seed at startup should do just that.
This works by taking the key passed as a system property if one
is passed, otherwise picking a random long and getting it into
appropriate key format. The build just calls
`new Random().nextLong()` to get the seed while randomized testing
uses a Murmur3 hash of `System.nanoTime`.
This change skips rest tests that use mutlitple types if the cluster
is a pure 6.x cluster. This allows all indics to be created with a version
less than 6.0 and that means we can safely use the `mapping.single_type` setting.

The PR takes a different approach to solve #24806 than currently implemented via #25052. The `refreshMetric` that IndexShard maintains is updated using the refresh listeners infrastructure in lucene. This means that we truly count all refreshes that lucene makes and not have to worry about each individual caller (like `IndexShard@refresh` and `Engine#get()`)
parent/child: Allow updating mapping without specifying `_parent` field on each update.
Prior to this change when a mapping has a `_parent` field then any update (also updates that didn't modify the `_parent` field) to the mapping involved specifying the `_parent` field again. With this change specifying the `_parent` field on each mapping update is no longer required.
Closes#23381
We have a callback interface that is not needed because it is
effectively the same as java.util.function.Consumer. This commit removes
it.
Relates #25089
We use a callback in recovery land during primary relocation to ensure
the relocation target is on at least the same version as the relocation
source. This callback is typed as a Callback<Long> which is an
unnecessary custom type (we can use Consumer<T> or the appropriate
primitive callbacks). Here, we can use LongConsumer.

Previous work modified the status code on the get aliases API when an
alias is missing so that these requests 404 now. This change was also
backported to 5.5 so we can adjust the skips to skip everything before
5.5.0.
Previously the HEAD and GET aliases endpoints were misaigned in
behavior. The HEAD verb would 404 if any aliases are missing while the
GET verb would not if any aliases existed. When HEAD was aligned with
GET, this broke the previous usage of HEAD to serve as an existence
check for aliases. It is the behavior of GET that is problematic here
though, if any alias is missing the request should 404. This commit
addresses this by modifying the behavior of GET to behave in this
way. This fixes the behavior for HEAD to also 404 when aliases are
missing.

This change moves the parent_id query to the parent-join module and handles the case when only the parent-join field can be declared on an index (index with single type on).
If single type is off it uses the legacy parent join field mapper and switch to the new one otherwise (default in 6).

This commit fixes the group methdos of Settings to properly include

but without the group prefix being removed.

Unknown patterns used to silently be ignored. This was a problem because users did not know they were providing an invalid pattern name, and maybe thought the rest of their regexes were invalid.
Fixes#22831.
During package install on systemd-based systems, some sysctl settings
should be set (e.g. vm.max_map_count).
In some environments, changing sysctl settings plainly does not work;
previously a global environment variable named
ES_SKIP_SET_KERNEL_PARAMETERS was introduced to skip calling sysctl, but
this causes trouble for:
- configuration management systems, which usually cannot apply an env
var when running a package manager
- package upgrades, which will not have the env var set any more, and
thus leaving the package management system in a bad state (possibly
half-way upgraded, can be very hard to recover)
This removes the env var again and instead of calling systemd-sysctl
manually, tells systemd to restart the wrapper unit - which itself can
be masked by system administrators or management tools if it is known
that sysctl does not work in a given environment.
The restart is not silent on systems in their default configuration, but
is ignored if the unit is masked.

The index parameter in the update-aliases, put-alias, and delete-alias APIs no longer accepts alias names. Instead, it accepts only index names (or wildcards which will expand to matching indices).
Closes#23960
This commit fixes a bug in retrieving a sub Settings object for a given
prefix with secure settings. Before this commit the returned Settings
would be filtered by the prefix, but the found setting names would not
have the prefix removed.
This is the first step towards adaptive replica selection (#24915). This PR
tracks the execution time, also known as the "service time" of a task in the
threadpool. The `QueueResizingEsThreadPoolExecutor` then stores a moving average
of these task times which can be retrieved from the executor.
Currently there is no functionality using the EWMA yet (other than tests), this
is only a bite-sized building block so that it's easier to review.

hold (resizing can result in a smaller size than the current size, while
the assert attempted to verify the new size is always greater than the
current).
REST handlers that require a body will throw an an ElasticsearchParseException "request body required".
REST handlers that require a body OR source param will throw an ElasticsearchParseException "request body or source param required".
Replaced asserts in BulkRequest parsing code with a more descriptive IllegalArgumentException if the line contains an empty object.
Updated bulk REST test to verify an empty action line is rejected properly.
Updated BulkRequestTests with randomized testing for an empty action line.
Used try-with-resouces for XContentParser in AbstractBulkByQueryRestHandler.
This adds an option to `ClusterConfiguration` to preserve the
`shared` directory when starting up a new cluster and switches
the `qa:full-cluster-restart` tests to use it rather than
disable the clean shared task.

This commit exposes the secure settings in Settings.Builder, so that
the current secure settings can be retrieved and added to when creating
settings for tests. This is necessary since secure settings can only be
added once to a builder, so chains of methods using settings builders
must reuse the already set mock secure settings.
Both gradle and java code attempt to infer the type of a each
Version constant in Version.java. It is super important that
they infer that each constant has the same type. If they disagree
we might accidentally not be testing backwards compatibility for
some version.
This adds a test to make sure that they agree, modulo known and
accepted differences (mostly around alphas). It also changes the
minimum wire compatible version from the released 5.4.0 to the
unreleased 5.5.0 as that lines up with the gradle logic.
Relates to #24798
Note that the gradle and java version logic doesn't actually match so
this contains a hack to make it *look* like it matches. Since this is a
start, I'm merging it and going to work on some followups to make the
logic actually match.....
When the jarhell check fails due to a duplicate jar on the classpath,
the exception message includes the full classpath but not the duplicated
jar. For a long classpath, this can make it difficult to find the jar
that is duplicated. This commit changes the exception message to include
the duplicated jar.

This removes the parsing of things like `GET /idx/_aliases,_mappings`, instead,
a user must choose between retriving all index metadata with `GET /idx`, or only
a specific form such as `GET /idx/_settings`.

This commit creates TemplateScript and associated classes so that
templates no longer need a special ScriptService.compileTemplate method.
The execute() method is equivalent to the old run() method.
relates #20426
* All public methods starting with get will be added as local variables
to the execute method.
* The execute method on a ScriptContext must be both public and
abstract. This method will be implemented by the Painless compiler.
* A static list of parameter names for the execute method must be
provided since the names will be eliminated at runtime.
* The uses$ methods will still be implemented as before.
* A single constructor may be provided by the ScriptContext. This
constructor will be overridden by the Painless compiler to include the
exact same arguments. This allows instances of a Painless script to
potentially contain state. If a constructor is not provided it is
assumed the default constructor with no arguments will be used.
We're using Vagrant in more places now than before. This commit includes a plugin that verifies
the Vagrant and Virtualbox installations for projects that depend on them. This shared code
should fix up the errors we've seen from CI builds relating to the new Kerberos fixture.
Previously, when allocating bytes for a BigArray, the array was created
(or attempted to be created) and only then would the array be checked
for the amount of RAM used to see if the circuit breaker should trip.
This is problematic because for very large arrays, if creating or
resizing the array, it is possible to attempt to create/resize and get
an OOM error before the circuit breaker trips, because the allocation
happens before checking with the circuit breaker.
This commit ensures that the circuit breaker is checked before all big
array allocations (note, this does not effect the array allocations that
are less than 16kb which use the [Type]ArrayWrapper classes found in
BigArrays.java). If such an allocation or resizing would cause the
circuit breaker to trip, then the breaker trips before attempting to
allocate and potentially running into an OOM error from the JVM.
Closes#24790
In #24605, logic was implemented to ensure that completed snapshots were
properly removed from the cluster state upon a change in master nodes.
This commit removes redundant logic that also attempted to clean up
completed snapshots from the cluster state on master election, but only
covered a limited case that was remedied in #24605.
This commit also adds a test to ensure cleaning up of completed
snapshots at the right moment in time when a master election happens
before finalizing a snapshot, as well as adds a check to handle the case
where the old master and new master could attempt to finalize the
snapshot and write the same blob to the repository simultaneously.
