With this commit we raise the limit of the child circuit breaker used in
the unit test for the circuit breaker service so it is high enough to trip
only the parent circuit breaker. The previous limit was 300 bytes but
theoretically (considering overhead) we could reach 346 bytes. Thus any
value larger than 300 bytes could trip the child circuit breaker leading
to spurious failures.

Java 11 seems to get more verbose on the ClassCastException we check for in
SearchDocumentationIT. This changes the test from asserting the exact exception
message to only checking the two classes involved are part of the message.
Closes#32029
The "source" field in SSource seems unused. If removed, it can also be removed
from the ctor, which in turn makes is possible to delete the sourceText in the
Walker class.
With this commit we disable the real-memory circuit breaker in REST
tests as this breaker is based on real memory usage over which we have
no (full) control in tests and the REST client is not yet ready to retry
on circuit breaker exceptions.
This is only meant as a temporary measure to avoid spurious test
failures while we ensure that the REST client can handle those
situations appropriately.

With this commit we disable the real-memory circuit breaker in tests
that inherit from `ESSingleNodeTestCase`. As this breaker is based on
real memory usage over which we have no (full) control in tests and
their purpose is also not to test the circuit breaker, we use the
deterministic circuit breaker implementation that only accounts for
explicitly reserved memory.

* Cleanup Duplication in `PainlessScriptEngine`
* Extract duplicate building of compiler settings to method
* Remove dead method params + dead constant in `ScriptProcessor`
The build was broken due to some issues with the merging of #32018. A
method that was public went private before the PR was merged. That did
not cause a merge conflict (so the PR was merged successfully). But it
did cause the build to fail.
This is related to #27260. It adds the SecurityNioHttpServerTransport
to the security plugin. It randomly uses the nio http transport in
security integration tests.
* Replace Ingest ScriptContext with Custom Interface
* Make org.elasticsearch.ingest.common.ScriptProcessorTests#testScripting more precise
* Don't mock script factory in ScriptProcessorTests
* Adjust mock script plugin in IT for new API
Metric config already whitelist scaled_floats, but it wasn't added to
the histo group config. This centralizes the mapping types map
so that both metrics and histo (and any future configs) use the same
map.
Fixes#32035
Make SnapshotInfo and CreateSnapshotResponse parsers lenient for backwards compatibility. Remove extraneous fields from CreateSnapshotRequest toXContent.
This commit allows for rebuilding watcher secure secrets via the
reload_secure_settings API call. The commit also renames a method in the
Notification Service to make it a bit more readable.
* Adds a new auto-interval date histogram
This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.
This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.
Closes#9572
* Adds documentation
* Added sub aggregator test
* Fixes failing docs test
* Brings branch up to date with master changes
* trying to get tests to pass again
* Fixes multiBucketConsumer accounting
* Collects more buckets than needed on shards
This gives us more options at reduce time in terms of how we do the
final merge of the buckeets to produce the final result
* Revert "Collects more buckets than needed on shards"
This reverts commit 993c782d117892af9a3c86a51921cdee630a3ac5.
* Adds ability to merge within a rounding
* Fixes nonn-timezone doc test failure
* Fix time zone tests
* iterates on tests
* Adds test case and documentation changes
Added some notes in the documentation about the intervals that can bbe
returned.
Also added a test case that utilises the merging of conseecutive buckets
* Fixes performance bug
The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).
The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.
Thee commit also adds more tests
* Changes to only do complex reduction on final reduce
* merge latest with master
* correct tests and add a new test case for 10k buckets
* refactor to perform bucket number check in innerBuild
* correctly derive bucket setting, update tests to increase bucket threshold
* fix checkstyle
* address code review comments
* add documentation for default buckets
* fix typo
This commit adds the _xpack/usage api to the high level rest client.
Currently in the transport api, the usage data is exposed in a limited
fashion, at most giving one level of helper methods for the inner keys
of data, but then exposing thos subobjects as maps of objects. Rather
than making parsers for every set of usage data from each feature, this
PR exposes the entire set of usage data as a map of maps.
Other watcher actions already account for secure settings in their
sensitive settings, whereas the email sending action did not. This adds
the ability to optionally set a secure_password for email accounts.
Previously, the ensureWatchExists was overridable. This commit makes
it final so that it cannot be overridden, and cleans up some redundant
code in the process.
There was still a case with a null text that allowed for 0 attachments
to be created. This commit ensures that greater than zero are created
if the text is null. Otherwise, it uses the same logic to create 0 to 3
random attachments.
Closes#31948
We can leverage the composite agg's new `missing_bucket` feature on
terms groupings. This means the aggregation criteria used in the indexer
will now return null buckets for missing keys.
Because all buckets are now returned (even if a key is null),
we can guarantee correct doc counts with
"combined" jobs (where a job rolls up multiple schemas). This was
previously impossible since composite would ignore documents that
didn't have _all_ the keys, meaning non-overlapping schemas would
cause composite to return no buckets.
Note: date_histo does not use `missing_bucket`, since a timestamp is
always required.
The docs have been adjusted to recommend a single, combined job. It
also makes reference to the previous issue to help users that are upgrading
(rather than just deleting the sections).
The previous errors in compileJava were not cause by the brackets but my the
content of the @link section. Corrected this so its a working javadoc link again.
Because this is a static method on a public API, and one that we encourage
plugin authors to use, the method with the typo is deprecated in 6.x
rather than just renamed.
Implement buildSrc Version in java

- Will prevent eclipse from tangling up in this setup
- make it possible to use Version from Java
With this commit we introduce a new circuit-breaking strategy to the parent
circuit breaker. Contrary to the current implementation which only accounts for
memory reserved via child circuit breakers, the new strategy measures real heap
memory usage at the time of reservation. This allows us to be much more
aggressive with the circuit breaker limit so we bump it to 95% by default. The
new strategy is turned on by default and can be controlled with the new cluster
setting `indices.breaker.total.userealmemory`.
Note that we turn it off for all integration tests with an internal test cluster
because it leads to spurious test failures which are of no value (we cannot
fully control heap memory usage in tests). All REST tests, however, will make
use of the real memory circuit breaker.

When an ML job cannot be allocated to a node the exception
contained an explanation of why the job couldn't be
allocated to each node in the cluster. For large clusters
this was not particularly easy to read and made the error
displayed in the UI look very scary.
This commit changes the structure of the error to an outer
ElasticsearchException with a high level message and an
inner IllegalStateException containing the detailed
explanation. Because the definition of root cause is the
innermost ElasticsearchException the detailed explanation
will not be the root cause (which is what Kibana displays).
Fixes#29950
Historically we have loaded SSL objects (such as SSLContext,
SSLIOSessionStrategy) by passing in the SSL settings, constructing a
new SSL configuration from those settings and then looking for a
cached object that matches those settings.
The primary issue with this approach is that it requires a fully
configured Settings object to be available any time the SSL context
needs to be loaded. If the Settings include SecureSettings (such as
passwords for keys or keystores) then this is not true, and the cached
SSL object cannot be loaded at runtime.
This commit introduces an alternative approach of naming every cached
ssl configuration, so that it is possible to load the SSL context for
a named configuration (such as "xpack.http.ssl"). This means that the
calling code does not need to have ongoing access to the secure
settings that were used to load the configuration.
This change also allows monitoring exporters to use SSL passwords
from secure settings, however an exporter that uses a secure SSL setting
(e.g. truststore.secure_password) may not have its SSL settings updated
dynamically (this is prevented by a settings validator).
Exporters without secure settings can continue to be defined and updated
dynamically.
It looks like we weren't clear on when and why you should close the high
level client and folks were closing it after every request which is not
efficient. This explains why you should close the client and when so
this shouldn't be as common.

This is related to #27260. It adds the SecurityNioTransport to the
security plugin. Additionally, it adds support for ip filtering. And it
randomly uses the nio transport in security integration tests.
Currently AbstractXContentTestCase#testFromXContent appends random fields, but in
a fixed position. This PR shuffles all fields after the random fields have been appended,
hence the random fields are actually added to random positions.
Forces fetch tasks to queue even in the event that the queue is
already full. The reasoning is that fetch tasks may only be follow-up
to query tasks, so the number of additional fetch tasks that may enter
the threadpool is expected to be reasonable.
Closes#29442
The `else` branch where currently the error response should be thrown is not
reachable because `handler` is always non-null inside the previous outer check.
Moving error creation into an else branch on the other condition check, removing
the other superflous check for non-null handler inside the first branch.
This test produced different implementations of joda time classes,
depending on if the data was serialized or not (DateTime vs
MutableDateTime). This now uses a common base class to extract the
milliseconds from the data.

This change adds Expected Reciprocal Rank (ERR) as a ranking evaluation metric
as descriped in:
Chapelle, O., Metlzer, D., Zhang, Y., & Grinspan, P. (2009).
Expected reciprocal rank for graded relevance.
Proceeding of the 18th ACM Conference on Information and Knowledge Management.
https://doi.org/10.1145/1645953.1646033
ERR is an extension of the classical reciprocal rank to the graded relevance
case and assumes a cascade browsing model. It quantifies the usefulness of a
document at rank `i` conditioned on the degree of relevance of the items at ranks
less than `i`. ERR seems to be gain traction as an alternative to (n)DCG, so it
seems like a good metric to support. Also ERR seems to be the default optimization
metric used for training in RankLib, a widely used learning to rank library.
