The packaging tests currently have a couple different ways of deciding
where temp files should be placed, and then sometimes used fixed file
or directory names within that dir. This commit conslidates some of that
temp dir handling by making it more compatible with the handling that
exists within the bats tests, where /tmp is not always appropriate due
to how systemd interacts with it. This commit also adds a utility
methhod for creating temp dirs, so as to ensure the new directory is
created as if a umask of 022 were used, which is not the case when using
Files.createTempDirectory without a set of permissions (it assumes 077).
This change allows to use an `index_filter` in the
field capabilities API. Indices are filtered from
the response if the provided query rewrites to `match_none`
on every shard:
````
GET metrics-*
{
"index_filter": {
"bool": {
"must": [
"range": {
"@timestamp": {
"gt": "2019"
}
}
}
}
}
````
The filtering is done on a best-effort basis, it uses the can match phase
to rewrite queries to `match_none` instead of fully executing the request.
The first shard that can match the filter is used to create the field
capabilities response for the entire index.

This template was added for 7.0 for what I am guessing is a BWC issue related to deprecation
warnings. It unfortunately seems to cause failures because templates for these tests are not cleared
after the test (because these are upgrade tests).
Resolves#56363
* Remove usage of deprecated testCompile configuration
* Replace testCompile usage by testImplementation
* Make testImplementation non transitive by default (as we did for testCompile)
* Update CONTRIBUTING about using testImplementation for test dependencies
* Fail on testCompile configuration usage
This commit re-enables windows testing for archives packaging tests.
These were disabled previously because of constant failure due to
windows file locks, but the failure does not occur outside of CI, so
they are being re-enabled to further investigate the failure.

We can't use the high level create snapshot request any longer
since we changed some of its default parameters in `8` and those
are not understood by older versions like `7.4`.
Closes#57650
Almost every outbound message is serialized to buffers of 16k pagesize.
We were serializing these messages off the IO loop (and retaining the concrete message
instance as well) and would then enqueue it on the IO loop to be dealt with as soon as the
channel is ready.
1. This would cause buffers to be held onto for longer than necessary, causing less reuse on average.
2. If a channel was slow for some reason, not only would concrete message instances queue up for it, but also 16k of buffers would be reserved for each message until it would be written+flushed physically.
With this change, the serialization happens on the event loop which effectively limits the number of buffers that `N` IO-threads will ever use so long as messages are small and channels writable.
Also, this change dereferences the reference to the concrete outbound message as soon as it has been serialized to save some more on GC.
This reduces the GC time for a default PMC run by about 50% in experiments (3 nodes, 2G heap each, loopback ... obvious caveat is that GC isn't that heavy in the first place with recent changes but still a measurable gain).
I also expect it to be helpful for master node stability by causing less of a spike if master is e.g. hit by a large number of requests that are processed batched (e.g. shard snapshot status updates) and responded to in a short time frame all at once.
Obviously, the downside to this change is that it introduces more latency on the IO loop for the serialization. But since we read all of these messages on the IO loop as well I don't see it as much of a qualitative change really and the more predictable buffer use seems much more valuable relatively.
As the datastream information is stored in the `ClusterState.Metadata` we exposed
the `Metadata` to the `AsyncWaitStep#evaluateCondition` method in order for
the steps to be able to identify when a managed index is part of a DataStream.
If a managed index is part of a DataStream the rollover target is the DataStream
name and the highest generation index is the write index (ie. the rolled index).

The new translog bwc test checks a corruption case before 6.3.0.
However, it needs to restart the old node to reproduce, which does not
currently work given how testclusters works when plugins are installed.
As a workaround, this commit omits creating bwc tests before 6.3.0 only
when the default distribution is used.
fixes#57252
If an upgraded node is restarted multiple times without flushing a new
index commit, then we will wrongly exclude all commits from the starting
commits. This bug is reproducible with these minimal steps: (1) create
an empty index on 6.1.4 with translog retention disabled, (2) upgrade
the cluster to 7.7.0, (3) restart the upgraded the cluster. The problem
is that with the new translog policy can trim translog without having a
new index commit, while the existing commit still refers to the previous
translog generation.
Closes#57091
The packaging tests start elasticsearch in various ways. All of these
currently expect it is started asynchronously, yet some tests expect it
will fail to start and want to check the error output. This commit adds
a daemonize flag to the utility methods to start elasticsearch for such
cases, so that when the start method returns, all the error output
should already be available since the process will have exited.

In normal operation native controllers are not expected to write
anything to stdout or stderr. However, if due to an error or
something unexpected with the environment a native controller
does write something to stdout or stderr then it will block if
nothing is reading that output.
This change makes the stdout and stderr of native controllers
reuse the same stdout and stderr as the Elasticsearch JVM (which
are by default redirected to es.stdout.log and es.stderr.log) so
that if something unexpected is written to native controller
output then:
1. The native controller process does not block, waiting for
something to read the output
2. We can see what the output was, making it easier to debug
obscure environmental problems

Firstly, backport the use of tini as the Docker entrypoint. This was supposed
to have been done following #50277, but was missed. It isn't a direct backport
as this branch will continue using root as the initial Docker user.
Secondly, backport #55491 to use the official checksums when downloading tini.
Backport of #55115.
Replace calls to deprecate(String,Object...) with deprecateAndMaybeLog(...),
with an appropriate key, so that all messages can potentially be deduplicated.
In bash, checking for whether an env variable exists uses the -z test,
against a stringified env var, so that the test is actually whether the
env var is empty, but not necessarily undefined. We use this to test
whether JAVA_HOME is set, to determine whether the bundled jdk should be
used. In windows, this test is an actual "undefined" check. This commit
brings the behavior on two systems in sync, opting to allow for an empty
JAVA_HOME in windows to indicate the bundled jdk should be used.

difficult) in the new VS framework.
This refactor consolidates both factories together and introduces
a PercentilesConfig object to act as a standardized way to pass
algo-specific parameters through the factory. This object
is then used when deciding which kind of aggregator to create

Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
Currently forbidden apis accounts for 800+ tasks in the build. These
tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance
(https://github.com/policeman-tools/forbidden-apis/pull/162), but we
need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis
usages, in preparation for upgrading to 3.0 when it is released.
Backport of #55073.
We added tasks to build an ARM distribution and Docker image, but didn't
provide any way to run packaging tests against them. Add extra loops on
the possible Architecture values, and skip tasks that can't be run on
the current Architecture.
Apply the :distribution:archives naming convention to some of the Docker
sub-projects, so that we have a more consistent naming scheme.
Also, we've seen some examples of Docker packaging tests failing sporadically
when they try to clean up the temp directory, citing a not-empty
directory. Ensure that any running container is removed before cleaning
up the temp dir, in an effort to avoid this problem.
This change converts the module and plugin parameters
for testClusters to be lazy. Meaning that the values
are not resolved until they are actually used. This
removes the requirement to use project.afterEvaluate to
be able to resolve the bundle artifact.
Note - this does not completely remove the need for afterEvaluate
since it is still needed for the custom resource extension.
This commit includes a number of changes to reduce overall build
configuration time. These optimizations include:
- Removing the usage of the 'nebula.info-scm' plugin. This plugin
leverages jgit to load read various pieces of VCS information. This
is mostly overkill and we have our own minimal implementation for
determining the current commit id.
- Removing unnecessary build dependencies such as perforce and jgit
now that we don't need them. This reduces our classpath considerably.
- Expanding the usage lazy task creation, particularly in our
distribution projects. The archives and packages projects create
lots of tasks with very complex configuration. Avoiding the creation
of these tasks at configuration time gives us a nice boost.
`scripted_metric` did not work with cross cluster search because it
assumed that you'd never perform a partial reduction, serialize the
results, and then perform a final reduction. That
serialized-after-partial-reduction step was broken.
This is also required to support #54758.
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
This drop the "top level" pipeline aggregators from the aggregation
result tree which should save a little memory and a few serialization
bytes. Perhaps more imporantly, this provides a mechanism by which we
can remove *all* pipelines from the aggregation result tree. This will
save quite a bit of space when pipelines are deep in the tree.
Sadly, doing this isn't simple because of backwards compatibility. Nodes
before 7.7.0 *need* those pipelines. We provide them by setting passing
a `Supplier<PipelineTree>` into the root of the aggregation tree that we
only call if we need to serialize to a version before 7.7.0.
This solution works for cross cluster search because we always reduce
the aggregations in each remote cluster and then forward them back to
the coordinating node. Its quite possible that the coordinating node
needs the pipeline (say it is version 7.1.0) and the gateway node in the
remote cluster doesn't (version 7.7.0). In that case the data nodes
won't send the pipeline aggregations back to the gateway node.
Critically, the gateway node *will* send the pipeline aggregations back
to the coordinating node. This is all managed with that
`Supplier<PipelineTree>`, but *how* it is managed is a bit tricky.
