This is related to #27260. Currently when we queue a write with a
channel we set OP_WRITE and wait until the next selection loop to flush
the write. However, if the channel does not have a pending write, it
is probably ready to flush. This PR implements an optimistic flush logic
that will attempt this flush.
- All rollup pages should be marked as experimental instead of just
the top page
- While the job config docs state which aggregations are allowed, adding
a section which specifically details this in one place is more convenient
for the user
- Add a clarification that the DeleteJob API does not delete the rollup
data, just the rollup job.
Cross-cluster search selects a subset of nodes for each remote cluster
and sends requests only to them, which will act as a proxy and properly
redirect such requests to the target nodes that hold the relevant data.
What happens today is that every time we send a request to a remote
cluster, it will be sent to the next node in the proxy list
(in round-robin fashion), regardless of whether the target node is
already amongst the ones that we are connected to. In case for instance
we need to send a shard search request to a data node that's also one of
the selected proxy nodes, we may end up sending the request to it
through one of the other proxy nodes.
This commit optimizes this case to make sure that whenever we are
already connected to a remote node, we will send a direct request rather
than using the next proxy node.
There is a side-effect to this, which is that round-robin will be a bit
unbalanced as the data nodes that are also selected as proxies will
receive more requests.
The parser for the Metric config was directly instantiating
the config object, rather than using the builder. That means it was
bypassing the validation logic built into the builder, and would allow
users to create invalid metric configs (like using unsupported metrics).
The job would later blow up and abort due to bad configs, but this isn't
immediately obvious to the user since the PutJob API succeeded.
This change prevents a datafeed using cross cluster search from starting if the remote cluster
does not have x-pack installed and a sufficient license. The check is made only when starting a
datafeed.
We have some use cases for an index setting to only be manageable by
dedicated APIs rather than be updateable via the update settings
API. This commit adds the notion of an internal index setting. Such
settings can be set on create index requests, they can not be changed
via the update settings API, yet they can be changed by action on behalf
of or triggered by the user via dedicated APIs.
The `requires_replica` yaml test feature hasn't worked for years. This
is what happens if you try to use it:
```
> Throwable #1: java.lang.NullPointerException
> at __randomizedtesting.SeedInfo.seed([E6602FB306244B12:6E341069A8D826EA]:0)
> at org.elasticsearch.test.rest.yaml.Features.areAllSupported(Features.java:58)
> at org.elasticsearch.test.rest.yaml.section.SkipSection.skip(SkipSection.java:144)
> at org.elasticsearch.test.rest.yaml.ESClientYamlSuiteTestCase.test(ESClientYamlSuiteTestCase.java:321)
```
None of our tests use it.
With #29331 we added support for the cluster health API to the
high-level REST client. The transport client does not support the level
parameter, and it always returns all the info needed for shards level
rendering. We have maintained that behaviour when adding support for
cluster health to the high-level REST client, to ease migration, but the
correct thing to do is to default the high-level REST client to
`cluster` level, which is the same default as when going through the
Elasticsearch REST layer.
If the publishing of a cluster state to a node fails, we currently only log it as debug information and
only on the master. This makes it hard to see the cause of (test) failures when logging is set to
default levels. This PR adds a warn level log on the node receiving the cluster state when it fails to
deserialise the cluster state and a warn level log on the master with a list of nodes for which
publication failed.
Today, if GET /_cluster/health?wait_for_active_shards=all does not immediately
succeed then it throws an exception due to an erroneous and unnecessary call to
ActiveShardCount#enoughShardsActive(). This commit fixes this logic.
Fixes#31151
Rules allow users to supply a detector with domain
knowledge that can improve the quality of the results.
The model detects statistically anomalous results but it
has no knowledge of the meaning of the values being modelled.
For example, a detector that performs a population analysis
over IP addresses could benefit from a list of IP addresses
that the user knows to be safe. Then anomalous results for
those IP addresses will not be created and will not affect
the quantiles either.
Another example would be a detector looking for anomalies
in the median value of CPU utilization. A user might want
to inform the detector that any results where the actual
value is less than 5 is not interesting.
This commit introduces a `custom_rules` field to the `Detector`.
A detector may have multiple rules which are combined with `or`.
A rule has 3 fields: `actions`, `scope` and `conditions`.
Actions is a list of what should happen when the rule applies.
The current options include `skip_result` and `skip_model_update`.
The default value for `actions` is the `skip_result` action.
Scope is optional and allows for applying filters on any of the
partition/over/by field. When not defined the rule applies to
all series. The `filter_id` needs to be specified to match the id
of the filter to be used. Optionally, the `filter_type` can be specified
as either `include` (default) or `exclude`. When set to `include`
the rule applies to entities that are in the filter. When set to
`exclude` the rule only applies to entities not in the filter.
There may be zero or more conditions. A condition requires `applies_to`,
`operator` and `value` to be specified. The `applies_to` value can be
either `actual`, `typical` or `diff_from_typical` and it specifies
the numerical value to which the condition applies. The `operator`
(`lt`, `lte`, `gt`, `gte`) and `value` complete the definition.
Conditions are combined with `and` and allow to specify numerical
conditions for when a rule applies.
A rule must either have a scope or one or more conditions. Finally,
a rule with scope and conditions applies when all of them apply.
TransportAction has many variants of execute. One of those variants
executes by returning a future, which is then often blocked on by
calling get(). This commit removes this variant of execute, instead
using a helper method for tests that want to block, or having tests
pass in a PlainActionFuture directly as a listener.

Currently the http pipelining handlers seem to support chunked http
content. However, this does not make sense. There is a content
aggregator in the pipeline before the pipelining handler. This means the
pipelining handler should only see full http messages. Additionally, the
request handler immediately after the pipelining handler only supports
full messages.
This commit modifies both nio and netty4 pipelining handlers to assert
that an inbound message is a full http message. Additionally it removes
the tests for chunked content.
This was silly; Bouncy Castle has an armored input stream for reading
keys in ASCII armor format. This means that we do not need to strip the
header ourselves and base64 decode the key. This had problems anyway
because of discrepancies in the padding that Bouncy Castle would produce
and the JDK base64 decoder was expecting. Now that we armor input/output
the whole way during tests, we fix all random failures in test cases
too.
The default wait_for_active_shards is NONE for cluster health, which
differs from all the other API in master, hence we need to make sure to
set the parameter whenever it differs from NONE (0). The test around
this also had a bug, which is why this was not originally uncovered.

This commit removes all the API methods that accept a `Header` varargs
argument, in favour of the newly introduced API methods that accept a
`RequestOptions` argument.

Here is the problem: if two threads are racing and one hits a failure
freeing a context and the other succeeded, we can expose the value of
the has failure marker to the succeeding thread before the failing
thread has had a chance to set the failure marker. This is a problem if
the failing thread counted down the expected number of operations, then
be put to sleep by a gentle lullaby from the OS, and then the other
thread could count down to zero. Since the failing thread did not get to
set the failure marker, the succeeding thread would respond that the
clear scroll succeeded and that makes that thread a liar. This commit
addresses by first setting the failure marker before we potentially
expose its value to another thread.
This is in preparation of pushing the new
rules design in the `ml-cpp` side. These
tests will be switched on again after merging
in the new rules implementation.
* Support RequestedAuthnContext
This implements limited support for RequestedAuthnContext by :
- Allowing SP administrators to define a list of authnContextClassRef
to be included in the RequestedAuthnContext of a SAML Authn Request
- Veirifying that the authnContext in the incoming SAML Asertion's
AuthnStatement contains one of the requested authnContextClassRef
- Only EXACT comparison is supported as the semantics of validating
the incoming authnContextClassRef are deployment dependant and
require pre-established rules for MINIMUM, MAXIMUM and BETTER
Also adds necessary AuthnStatement validation as indicated by [1] and

The response currently implements ToXContentFragment although the only time it's used
it is supposed to print out a complete object rather than a fragment. Note that this
is the client version of the response, used only in the high-level client.
Given the weirdness of the response returned by the get alias API, we went for a client specific response, which allows us to hold the error message, exception and status returned as part of the response together with aliases. See #30536 .

Trying to post a new watch without any body currently results in a
NullPointerException. This change fixes that by validating that
Post and Put requests always have a body.
