The test FW has a method to check that it's implementation of getting
index and wire compatible versions as well as reasoning about which
version is released or not produces the same rezults as the simillar
implementation in the build.
This PR adds the `verifyVersions` task to the test FW so we have one
task to check everything related to versions.
This change fixes a bug that can occur when a shard failure is detected while we build
the search response and accept partial failures in set to false. In this case we currently
call onFailure on the provided listener but also continue the search as if the failure didn't
occur. This can lead to a listener called twice, once with onFailure and once with onSuccess
which is forbidden by design.
This commit is similar to the optimization made in #45765. With this
change, we fsync most of the data of the current generation without
holding writeLock when trimming unreferenced readers.

Especially in the snapshot code there's a lot
of logic chaining `ActionRunnables` in tricky
ways now and the code is getting hard to follow.
This change introduces two convinience methods that
make it clear that a wrapped listener is invoked with
certainty in some trickier spots and shortens the code a bit.
In order to work with external elasticsearch plugins, some parts of
build-tools need to know when the current build is part of the
elasticsearch project or an external build. We identify these "internal"
builds by a marker in our buildSrc classpath. However, some build-tools
integ tests need to override this flag to test both the external and
internal behavior.
This commit moves the storage of the flag indicating whether we are
running in an internal build to global build info. This will allow
testkit projects to override the flag.
This adds an SField node that operates similarly to SFunction as a top level
node meant only for use in an SClass node. Member fields are generated
for both class bindings and instance bindings using the new SField node
during the semantic pass, and information is no longer passed through
Globals for this during the write pass.
Backport of (#47721) for 7.x.
Similarly to #47582, Auto-follow patterns creates following
indices as long as the remote index matches the pattern and
the remote primary shards are all started. But since 7.2 closed
indices are also replicated, and it does not play well with CCR
auto-follow patterns as they create following indices for closed
leader indices too.
This commit changes the getLeaderIndicesToFollow() so that closed
indices are excluded from auto-follow patterns.
The global build info plugin prints high level information about the
build, including the test seed. However, BuildPlugin sets up the test
seed, which creates an odd implicit dependency on it. This commit moves
the intialization of the testSeed property into the global build info.
This is the first iteration in improving of handling of out of

LINESTRING (0 0, 720 20) is now decomposed into 3 strings:
multilinestring (
(0.0 0.0, 180.0 5.0),
(-180.0 5.0, 180 15),
(-180.0 15.0, 0 20)
)
It also fixes issues with linestrings that intersect antimeridian
more than 5 times.

Currently in the x content serialization tests we compare the exception
messages that are serialized. These exceptions messages are not
equivalent because the exception often changes when serialized to x
content. This commit removes this assertion.
Currently there are two issues with serializing BulkByScrollResponse.
First, when deserializing from XContent, indexing exceptions and search
exceptions are switched. Additionally, search exceptions do no retain
the appropriate RestStatus code, so you must evaluate the status code
from the exception. However, the exception class is not always correctly
retained when serialized.
This commit adds tests in the failure case. Additionally, fixes the
swapping of failure types and adds the rest status code to the search
failure.
If a cluster sending monitoring data is unhealthy and triggers an
alert, then stops sending data the following exception [1] can occur.
This exception stops the current Watch and the behavior is actually
correct in part due to the exception. Simply fixing the exception
introduces some incorrect behavior. Now that the Watch does not
error in the this case, it will result in an incorrectly "resolved"
alert. The fix here is two parts a) fix the exception b) fix the
following incorrect behavior.
a) fixing the exception is as easy as checking the size of the
array before accessing it.
b) fixing the following incorrect behavior is a bit more intrusive
- Note - the UI depends on the success/met state for each condition
to determine an "OK" or "FIRING"
In this scenario, where an unhealthy cluster triggers an alert and
then goes silent, it should keep "FIRING" until it hears back that
the cluster is green. To keep the Watch "FIRING" either the index
action or the email action needs to fire. Since the Watch is neither
a "new" alert or a "resolved" alert, we do not want to keep sending
an email (that would be non-passive too). Without completely changing
the logic of how an alert is resolved allowing the index action to
take place would result in the alert being resolved. Since we can
not keep "FIRING" either the email or index action (since we don't
want to resolve the alert nor re-write the logic for alert resolution),
we will introduce a 3rd action. A logging action that WILL fire when
the cluster is unhealthy. Specifically will fire when there is an
unresolved alert and it can not find the cluster state.
This logging action is logged at debug, so it should be noticed much.
This logging action serves as an 'anchor' for the UI to keep the state
in an a "FIRING" status until the alert is resolved.
This presents a possible scenario where a cluster starts firing,
then goes completely silent forever, the Watch will be "FIRING"
forever. This is an edge case that already exists in some scenarios
and requires manual intervention to remove that Watch.
This changes changes to use a template-like method to populate the
version_created for the default monitoring watches. The version is
set to 7.5 since that is where this is first introduced.

* Separate SLM stop/start/status API from ILM
This separates a start/stop/status API for SLM from being tied to ILM's
operation mode. These APIs look like:
```
POST /_slm/stop
POST /_slm/start
GET /_slm/status
```
This allows administrators to have fine-grained control over preventing
periodic snapshots and deletions while performing cluster maintenance.

Failed snapshots will eventually build up unless they are deleted. While
failures may not take up much space, they add noise to the list of
snapshots and it's desirable to remove them when they are no longer
useful.
With this change, failed snapshots are deleted using the following
strategy: `FAILED` snapshots will be kept until the configured
`expire_after` period has passed, if present, and then be deleted. If
there is no configured `expire_after` in the retention policy, then they
will be deleted if there is at least one more recent successful snapshot
from this policy (as they may otherwise be useful for troubleshooting
purposes). Failed snapshots are not counted towards either `min_count`
or `max_count`.
The "Conditionals with the Pipeline Processor" incorrectly documents
how to create a pipeline of pipelines with a failure condition. The
example as-is will always execute the fail processor. The change here
updates the documentation to correct guard the fail processor with an
if condition.
Similar to #47507. We are throwing `SnapshotException` when
you (and SLM tests) would expect a `SnapshotMissingException`
for concurrent snapshot status and snapshot delete operations
with a very low probability.
Fixed the exception type and added a test for this scenario.
We're needlessly wrapping a `SnapshotMissingException` which
itself is a `SnapshotException` when trying to load a missing
snapshot. This leads to failure #47442 which expects a
`SnapshotMissingException` in this case.

When exceptions could be returned from another node, the exception
might be wrapped in a `RemoteTransportException`. In places where
we handled specific exceptions using `instanceof` we ought to unwrap
the cause first.
This commit attempts to fix this issue after searching code in the ML
plugin.
Backport of #47676
* Convert RunTask to use testclusers, remove ClusterFormationTasks
This PR adds a new RunTask and a way for it to start a
testclusters cluster out of band and block on it to replace
the old RunTask that used ClusterFormationTasks.
With this we can now remove ClusterFormationTasks.
Importing dangling indices with aliases risks breaking functionalities
using those aliases. For instance, writing to an alias may break if
there is no is_write_index indication on the existing alias and the
dangling index import adds a second index to the alias. Or an
application could have an assumption about the alias only ever pointing
to one index and suddenly seeing the alias also linked to an old index
could break it. With this change we strip aliases of the index meta data
found before importing a dangling index.
Setting `cluster.routing.allocation.disk.include_relocations` to `false` is a
bad idea since it will lead to the kinds of overshoot that were otherwise fixed
in #46079. This commit deprecates this setting so it can be removed in the next
major release.
Previously when retrieving an SLM policy it would always return a 200
with `{}` in the body, even if the policy did not exist. This changes
that behavior to throw an error (similar to our other APIs) if a
policy doesn't exist.
This also adds a basic CRUD yml test for the behavior.

The example use of a scoring script was incorrectly using a filter
script query, which has no scoring, and thus no _score variable
avialable. This commit converts the example doc to using the newer
script_score query.
If a thread pool rejection exception happens, an alternative code
path is chosen to write history and delete the trigger. If an exception
happens during deletion of the trigger an exception may be thrown and not
caught.
This commit catches the exception and provides a meaning error message.

When deactivating a watch, there is a chance that it is fully deactivated
and reporting as not running but the history is not fully written yet.
There is not a tight coupling between the associated watcher history
index and the deactivation. This test assumes that once a watch is
deactivated that all history is fully written in a very short time period.
If the Watch is deactivated, but the history is slow to write it can result
in a failing test.
This change removes an assertion that assumes that the deactivation of a watch
ensured the all of the watch history was written. There is still a minor race
condition with respect to the remaining history assertions. However, if the
history is slow to be written, it will allow the test to still passing.

This has ELambda and ENewArrayFunctionRef add their generated synthetic
