Removing the deprecated "xpack.monitoring.enabled" setting introduced
log spam and potentially some failures in ML tests. It's possible to use
a different, non-deprecated setting to disable monitoring, so we do that
here.
* Add Snapshot Resiliency Test for Master Failover during Delete
We only have very indirect coverage of master failovers during snaphot delete
at the moment. This comment adds a direct test of this scenario and also
an assertion that makes sure we are not leaking any snapshot completion listeners
in the snapshots service in this scenario.
This gives us better coverage of scenarios like #54256 and makes the diff
to the upcoming more consistent snapshot delete implementation in #54705
smaller.
Adds ranged read support for GCS repositories in order to enable searchable snapshot support
for GCS.
As part of this PR, I've extracted some of the test infrastructure to make sure that
GoogleCloudStorageBlobContainerRetriesTests and S3BlobContainerRetriesTests are covering
similar test (as I saw those diverging in what they cover)
If we run into an INIT state snapshot and the current master didn't create it, it will be removed anyway.
=> no need to have that block another snapshot from starting.
This has practical relevance because on master fail-over after snapshot INIT but before start, the create snapshot request will be retried by the client (as it's a transport master node action) and needlessly fail with an unexpected exception (snapshot clearly didn't exist so it's confusing to the user).
This allowed making two disruption type tests stricter
* Fix Path Style Access Setting Priority
Fixing obvious bug in handling path style access if it's the only setting overridden by the
repository settings.
Closes#55407
isHidden was a `Boolean` in order to treat a special case identified
with V1 templates where if the create index request didn't specify if
the index should be hidden or not (ie. isHidden was `null`) but the
index matched a template that specified the `index.hidden` setting we
needed to remove the global templates from the templates we'll apply to
the new index (note: this is important with V1 templates as inheritance
is supported).
With V2 templates we match only one template with an index so the
equivalent check did not need to exist (we added a sanity check in
https://github.com/elastic/elasticsearch/pull/55015 where we make sure
we don't apply an invalid global template - one that specifes the
`index.hidden` setting, but this is a check we make irrespective of the
user specifying or not if the index should be hidden)
This commit makes `isHidden` when matching V2 templates a boolean
primitive, eliminating the need for the `null` state to exist. Note that
some methods which use the matching V2 templates still work with a
`Boolean` object `isHidden` attribute as they are also matching the V1
templates. These methods will pass in `false` instead of `null` when
finding the V2 templates.

In #55298 we saw a failure of `CoordinationStateTests#testSafety` in which a
single master-eligible node is bootstrapped, then rebooted as a
master-ineligible node (losing its persistent state) and then rebooted as a
master-eligible node and bootstrapped again.
This happens because this test loses too much of the persistent state; in fact
once bootstrapped the node would not allow itself to be bootstrapped again.
This commit adjusts the test logic to reflect this.
Closes#55298
This validation is not needed, as we have discovered the source of the
serialization error that was leading to some usage instances appearing
to not have a name.
This commit upgrades the ASM dependency used in the feature aware check
to 7.3.1. This gives support for JDK 14. Additionally, now that Gradle
understands JDK 13, it means we can remove a restriction on running the
feature aware check to JDK 12 and lower.
This change reworks the loading and monitoring of files that are used
for the construction of SSLContexts so that updates to these files are
not lost if the updates occur during startup. Previously, the
SSLService would parse the settings, build the SSLConfiguration
objects, and construct the SSLContexts prior to the
SSLConfigurationReloader starting to monitor these files for changes.
This allowed for a small window where updates to these files may never
be observed until the node restarted.
To remove the potential miss of a change to these files, the code now
parses the settings and builds SSLConfiguration instances prior to the
construction of the SSLService. The files back the SSLConfiguration
instances are then registered for monitoring and finally the SSLService
is constructed from the previously parse SSLConfiguration instances. As
the SSLService is not constructed when the code starts monitoring the
files for changes, a CompleteableFuture is used to obtain a reference
to the SSLService; this allows for construction of the SSLService to
complete and ensures that we do not miss any file updates during the
construction of the SSLService.
While working on this change, the SSLConfigurationReloader was also
refactored to reflect how it is currently used. When the
SSLConfigurationReloader was originally written the files that it
monitored could change during runtime. This is no longer the case as
we stopped the monitoring of files that back dynamic SSLContext
instances. In order to support the ability for items to change during
runtime, the class made use of concurrent data structures. The use of
these concurrent datastructures has been removed.
Closes#54867
Backport of #54999
* Fix security manager bug writing large blobs to GCS
This commit addresses a security manager permissions issue writing large
blobs (on the resumable upload path) to GCS. The underlying issue here
is that we need to wrap the close and write calls on the channel. It is
not enough to do this:
SocketAccess.doPrivilegedVoidIOException(
() -> Streams.copy(
inputStream,
Channels.newOutputStream(client().writer(blobInfo, writeOptions))));
This reason that this is not enough is because Streams#copy will be in
the stacktrace and it is not granted the security manager permissions
needed to close or write this channel. We only grant those permissions
to classes loaded in the plugin classloader, and Streams#copy is from
the parent classloader. This is why we must wrap the close and write
calls as privileged, to truncate the Streams#copy call out of the
stacktrace.
The reason that this issue is not caught in testing is because the size
of data that we use in testing is too small to trigger the large blob
resumable upload path. Therefore, we address this by adding a system
property to control the threshold, which we can then set in tests to
exercise this code path. Prior to rewriting the writeBlobResumable
method to wrap the close and write calls as privileged, with this
additional test, we are able to reproduce the security manager
permissions issue. After adding the wrapping, this test now passes.
* Fix forbidden APIs issue
* Remove leftover debugging
Some aggregations, such as the Terms* family, will use an alternate
class to represent unmapped shard results (while the rest of the aggs
use the same object but with some form of "empty" or "nullish" values
to represent unmapped).
This was problematic with AbstractWireSerializingTestCase because it
expects the instanceReader to always match the original class. Instead,
we need to use the NamedWriteable version so that the registry
can be consulted for the proper deserialization reader.
We have some Dockerfiles that reference Ubuntu 19.04, which is not an LTS
version and has now appears to have been retired from the Ubuntu repositories.
Switch to 18.04, which is the current long-term support version. This
also requires a switch from OpenJDK 12 to 11.
Also change a usage of 16.04 to 18.04, for consistency.
Security features in the license state currently do a dynamic check on
whether security is enabled. This is because the license level can
change the default security enabled state. This commit splits out the
check on security being enabled, so that the combo method of security
enabled plus license allowed is no longer necessary.
We believe there's no longer a need to be able to disable basic-license
features completely using the "xpack.*.enabled" settings. If users don't
want to use those features, they simply don't need to use them. Having
such features always available lets us build more complex features that
assume basic-license features are present.
This commit deprecates settings of the form "xpack.*.enabled" for
basic-license features, excluding "security", which is a special case.
It also removes deprecated settings from integration tests and unit
tests where they're not directly relevant; e.g. monitoring and ILM are
no longer disabled in many integration tests.
* [ML] fix bugs with prediction field value settings (#55333)
This fixes two unreleased bugs:
1. Prediction value type of `number` might show unexpected classes
Analytics created models may have class labels like `1, 5, 10` (or some collection of discrete, whole numbers). These labels are passed to the inference model config in the `classification_labels` field.
When the predicted value format is `numeric` it should attempt to see if the classification labels are provided and are numeric. If so, use those. If not, use the underlying value.
2. When supplying an update overwrite, inference was losing the default prediction field value. This is because it was not copied over in the copy ctor in the ClassificationConfig.Builder class.
closes#55332
If we start unbanning when the last child task completed and that child
task executed with a specific user, then unban requests are denied
because internal requests can't run with a user. We need to remove bans
with the current thread context.
While the current version of forbidden apis still does not support java
14, the warning message has become very noisy as we now require java 14
for the elasticsearch build. This commit replaces the warn log message
with a comment in the code.
This validates that if the winner v2 template is a global one, it doesn't specify the
index.hidden setting.

Enabled data streams and itv2 feature enabled system properties in server module's integ test task.
PR #54726 added java integration tests for data streams, so this is why these system properties
need to be enabled when running release build.
This fixes the long muted testHRDSplit. Some minor adjustments for modern day elasticsearch changes :).
The cause of the failure is that a new `by` field entering the model with an exceptionally high count does not cause an anomaly. We have since stopped combining the `rare` and `by` in this manner. New entries in a `by` field are not anomalous because we have no history on them yet.
closes https://github.com/elastic/elasticsearch/issues/32966
When a anomaly jobs, datafeeds, and analytics tasks are stopped, they enter an ephemeral state called `STOPPING`.
If the node executing the task fails while this is occurring, they could be stuck in the limbo state of `STOPPING`. It is best to mark the tasks as completed if they get reassigned to a node.
PR #51260 moved usage counts about mapping field types and analysis to
the `_cluster/stats` API.
This documents those stats in the response section of the cluster stats
API docs.
Hotfix to not run into stuck snapshots because of master circuit breaking these requests.
Given that these requests are very small and much of the memory associated with them is already allocated
when the circuit breaker kicks in, the risk of this change introducing a higher chance of master running out
of memory should be very small.
Closes#54714
Implement the use of scalar functions inside aggregate functions.
This allows for complex expressions inside aggregations, with or without
GROUBY as well as with or without a HAVING clause. e.g.:
```
SELECT MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) AS max, b
FROM test
GROUP BY b
HAVING MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) > 5
```
Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as
this is currently not implemented on the ElasticSearch side.

Backport from: #54726
The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.
In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.
Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

The "old jdk" tests are just testing support for downloading from oracle
prior to java 12.0.1, when oracle added a hash to the url. This commit
moves these tests into the openjdk tests (ie oracle download tests),
since adoptopenjdk does not have any change in behavior that needs to be
tested.
The pom files for our published artifacts are sent to maven central
during Elastic's release process, but we may not found out until then
that we have inadvertently broken the pom structure, as has happened
several times before. This commit adds validation of the pom file
specifically for the rules required by maven central.
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.

We do not validate the name is not null, and not empty. Even though it
never should be, we had a build failure where it appears that somehow
this did happen. We add some validation here, in case this really is
happening, we will have a more clear indication where this is coming
from, and of course, validation that name fits the implicit assumptions
that it is not null and not empty.

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

be moved in a subsequent PR.

- Moves the histo-specific bits over to xpack (e.g. the actual aggregator logic).

Doubly-so since percentiles/ranks are extra boiler-plate'y... should be much lighter for other aggs
