There is at most one model size stats document per bucket, but
during lookback a job can churn through many buckets very quickly.
This can lead to many cluster state updates if established model
memory needs to be updated for a given model size stats document.
This change rate limits established model memory updates to one
per job per 5 seconds. This is done by scheduling the updates 5
seconds in the future, but replacing the value to be written if
another model size stats document is received during the waiting
period. Updating the values in arrears like this means that the
last value received will be the one associated with the job in the
long term, whereas alternative approaches such as not updating the
value if a new value was close to the old value would not.
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
Add hard limit to the number of items
a filter may have. This serves to protect
from excessive overhead due to the filters
taking too much memory or lookups becoming
too expensive.
This change adds stats about forecasts, to the jobstats api as well as xpack/_usage. The following
information is collected:
_xpack/ml/anomaly_detectors/{jobid|_all}/_stats:
- total number of forecasts
- memory statistics (mean/min/max)
- runtime statistics
- record statistics
- counts by status
_xpack/usage
- collected by job status as well as overall (_all):
- total number of forecasts
- number of jobs that have at least 1 forecast
- memory, runtime, record statistics
- counts by status
Fixes#31395
Previously the call to register a listener for settings updates was in
each individual service, rather than in the notification service
itself. This change ensures that each child of the notification service
gets registered with the settings update consumer.
Significantly improve the example snippets in the documentation.
The examples are part of the test suite and checked nightly.
To help readability, the existing dataset was extended (test_emp renamed
to emp plus library).
Improve output of JDBC tests to be consistent with the CLI
Add lenient flag to JDBC asserts to allow type widening (a long is
equivalent to a integer as long as the value is the same).
* Default resolveFromHash to Hasher.NOOP
This changes the default behavior when resolving the hashing
algorithm from unrecognised hash strings, which was introduced in
#31234
A hash string that doesn't start with an algorithm identifier can
either be a malformed/corrupted hash or a plaintext password when
Hasher.NOOP is used(against warnings).
Do not make assumptions about which of the two is true for such
strings and default to Hasher.NOOP. Hash verification will subsequently
fail for malformed hashes.
Finally, do not log the potentially malformed hash as this can very
well be a plaintext password.
Resolves#31697

The xcontent parameters were not passed to the xcontent serialization
of the chain input for each chain. This could lead to wrongly stored
watches, which did not contain passwords but only their redacted counterparts, when an input inside of a chain input contained a password.
Proper cleanup of the docs snippet tests depends on detecting what is being tested (ML, Watcher, etc) this is deduced from the file path and so we must account for Windows and Unix path separators
testIncorrectPasswordHashingAlgorithm is based on the assumption
that the algorithm selected for the change password request is
different than the one selected for the NativeUsersStore.
pbkdf2_10000 is the same as pbkdf2 since 10000 is the default cost
factor for pbkdf2 and thus should not be used as an option for the
passwordHashingSettings.
Also make sure that the same algorithm is used for settings and
change password requests in other tests for consistency, even if
we expect to not reach the code where the algorithm is checked for
now.

Some proxies require all requests to have paths starting with / since
there are no relative paths at the HTTP connection level. Elasticsearch
assumes paths are absolute. In order to run rest tests against a cluster
behind such a proxy, set the system property
tests.rest.client_path_prefix to /.

It is useful to have a processor similar to
logstash-filter-fingerprint
in Elasticsearch. A processor that leverages a variety of hashing algorithms
to create cryptographically-secure one-way hashes of values in documents.
This processor introduces a pbkdf2hmac hashing scheme to fields in documents
for indexing
Support multiple system store types
When falling back to using the system keystore and - most usually -
truststore, do not assume that it will be a JKS store, but deduct
its type from {@code KeyStore#getDefaultKeyStoreType}. This allows
the use of any store type the Security Provider supports by setting
the keystore.type java security property.
As part of the changes in #31234,the password verification logic
determines the algorithm used for hashing the password from the
format of the stored password hash itself. Thus, it is generally
possible to validate a password even if it's associated stored hash
was not created with the same algorithm than the one currently set
in the settings.
At the same time, we introduced a check for incoming client change
password requests to make sure that the request's password is hashed
with the same algorithm that is configured to be used in the node
settings.
In the spirit of randomizing the algorithms used, the
{@code SecurityClient} used in the {@code NativeRealmIntegTests} and
{@code ReservedRealmIntegTests} would send all requests dealing with
user passwords by randomly selecting a hashing algorithm each time.
This meant that some change password requests were using a different
password hashing algorithm than the one used for the node and the
request would fail.
This commit changes this behavior in the two aforementioned Integ
tests to use the same password hashing algorithm for the node and the
clients, no matter what the request is.
Resolves#31670
Make password hashing algorithm/cost configurable for the
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are
whitelisted and can be selected in the relevant setting.
The TaskManager and TaskAwareRequest could return null when registering
a task according to their javadocs, but no implementations ever actually
did that. This commit removes that wording from the javadocs and ensures
null is no longer allowed.
* Remove deprecation warnings to prepare for Gradle 5
Gradle replaced `project.sourceSets.main.output.classesDir` of type
`File` with `project.sourceSets.main.output.classesDirs` of type
`FileCollection`
(see [SourceSetOutput](https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/java/org/gradle/api/tasks/SourceSetOutput.java))
Build output is now stored on a per language folder.
There are a few places where we use that, here's these and how it's
fixed:
- Randomized Test execution
- look in all test folders ( pass the multi dir configuration to the
ant runner )
- DRY the task configuration by introducing `basedOn` for
`RandomizedTestingTask` DSL
- Extend the naming convention test to support passing in multiple
directories
- Fix the standalon test plugin, the dires were not passed trough,
checked with a debuger and the statement had no affect due to a
missing `=`.
Closes#30354
* Only check Java tests, PR feedback
- Name checker was ran for Groovy tests that don't adhere to the same

This worked because the list is passed to `project.files` that does the
right thing.
* Revert "Only check Java tests, PR feedback"
This reverts commit 9bd9389875d8b88aadb50df57a45cd0d2b073241.

* Pass all dirs to name check
Only run on Java for build-tools, this is safe because it's a self test.
It needs more work before we could pass in the Groovy classes as well as
these inherit from `GroovyTestCase`
* remove self tests from name check
The self complicates the task setup and disable real checks on
build-tools.
With this change there are no more self tests, and the build-tools tests
adhere to the conventions.
The self test will be replaced by gradle test kit, thus the addition of
the Gradle plugin builder plugin.

With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.

* Add support for matching objects in lists
Makes it possible to have a key that points to a list and assert that a
certain object is present in the list. All keys have to be present and
values have to match. The objects in the source list may have additional
fields.
example:
```
match: { 'nodes.$master.plugins': { name: ingest-attachment } }
```
* Update plugin and module tests to work with other distributions
Some of the tests expected that the integration tests will always be ran
with the `integ-test-zip` distribution so that there will be no other
plugins loaded.
With this change, we check for the presence of the plugin without
assuming exclusivity.
* Allow modules to run on other distros as well
To match the behavior of tets.distributions
* Add and use a new `contains` assertion
Replaces the previus changes that caused `match` to do a partial match.
* Implement PR review comments
This creates a YAML test "features" that indices if the cluster being
tested has xpack installed (`xpack`) or if it does *not* have xpack
installed (`no_xpack`). It uses those features to centralize skipping
a few tests that fail if xpack is installed.
The plan is to use this in a followup to skip docs tests that require
xpack when xpack is not installed. We *plan* to use the declaration
of required license level on the docs page to generate the required
`skip`.
Closes#30933.
This pull request adds a full cluster restart test for a Rollup job.
The test creates and starts a Rollup job on the cluster and checks
that the job already exists and is correctly started on the upgraded
cluster.
This test allows to test that the persistent task state is correctly
parsed from the cluster state after the upgrade, as the status field
has been renamed to state in #31031.
The test undercovers a ClassCastException that can be thrown in
the RollupIndexer when the timestamp as a very low value that fits
into an integer. When it's the case, the value is parsed back as an
Integer instead of Long object and (long) position.get(rollupFieldName)
fails.
If no version is specified when putting a watch, the index API should be
used instead of the update API, so that the whole watch gets overwritten
instead of being merged with the existing one.
Merging only happens when a version is specified, so that credentials can be omitted, which is important for the watcher UI.
TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
We have made node selectors configurable per request, but all
of other language clients don't allow for that.
A good reason not to do so, is that having a different node selector
per request breaks round-robin. This commit makes NodeSelector
configurable only at client initialization. It also improves the docs
on this matter, important given that a single node selector can still
affect round-robin.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
This adds an api to allow updating a filter:
POST _xpack/ml/filters/{filter_id}/_update
The request body may have:
- description: setting a new description
- add_items: a list of the items to add
- remove_items: a list of the items to remove
This commit also changes the PUT filter api to
error when the filter_id is already used. As
now there is an api for updating filters, the
put api should only be used to create new ones.
Also, updating a filter results into a notification
message auditing the change for every job that is
using that filter.
In #29639 we added a `format` option to doc-value fields and deprecated usage
of doc-value fields without a format so that we could migrate doc-value fields
to use the format that comes with the mappings by default. However I missed to
fix the machine-learning datafeed extractor.
PkiRealm caches successful authentications and provides ways to
invalidate the cache. But in some scenario's the cache was not being
invalidated on role mapping change.
PkiRealm does not inform role mapper to be notified for cache
refresh on role mapping updates.
The logic in `TransportClearRealmCacheAction#nodeOperation`
which gets invoked for refreshing cache on realms, considers null or
empty realm names in the request as clear cache on all realms. When
LDAP realm is not present then it clears cache for all realms so it
works fine, but when LDAP realm is configured then role mapper
sends a request with LDAP realm names and so the cache is cleared
only for those realms.
This commit resolves the issue by registering PkiRealm with role
mapper for cache refresh. PkiRealm implements CachingRealm and as it
does not extend CachingUsernamePasswordRealm, have modified the
interface method `refreshRealmOnChange` to accept CachingRealm.
According to RFC 7617, the Basic authentication scheme name
should not be case sensitive.
Case insensitive comparisons are also applicable for the bearer
tokens where Bearer authentication scheme is used as per
RFC 6750 and RFC 7235
Some Http clients may send authentication scheme names in
different case types for eg. Basic, basic, BASIC, BEARER etc.,
so the lack of case-insensitive check is an issue when these
clients try to authenticate with elasticsearch.
This commit adds case-insensitive checks for Basic and Bearer
authentication schemes.
Closes#31486
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
The QueryCachingPolicy#ALWAYS_CACHE was deprecated in Lucene-7.4 and
will be removed in Lucene-8.0. This change replaces it with QueryCachingPolicy.
This also makes INDEX_QUERY_CACHE_EVERYTHING_SETTING visible in testing only.
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
The changes made to disable security for trial licenses unless security
is explicitly enabled caused issues when a 6.3 node attempts to join a
cluster that already has a production license installed. The new node
starts off with a trial license and `xpack.security.enabled` is not
set for the node, which causes the security code to skip attaching the
user to the request. The existing cluster has security enabled and the
lack of a user attached to the requests causes the request to be
rejected.
This commit changes the security code to check if the state has been
recovered yet when making the decision on whether or not to attach a
user. If the state has not yet been recovered, the code will attach
the user to the request in case security is enabled on the cluster
being joined.
Closes#31332
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
Currently, when we open a new channel, we pass it an
InboundChannelBuffer. The channel buffer is preallocated a single 16kb
page. However, there is no guarantee that this channel will be read from
anytime soon. Instead, this commit does not preallocate that page. That
page will be allocated when we receive a read event.
Since #30966, Action no longer has anything but a call to the
GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.
Relates #30603
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
This is related to #31325. There is currently information about the
get-trial-status api on the start-trial api documentation page. It also
has the incorrect route for that api. This commit removes that
information as the start-trial page properly links to a page providing
documenation about get-trial-status.
This pull request removes the relationship between the state
of persistent task (as stored in the cluster state) and the status
of the task (as reported by the Task APIs and used in various
places) that have been confusing for some time (#29608).
In order to do that, a new PersistentTaskState interface is added.
This interface represents the persisted state of a persistent task.
The methods used to update the state of persistent tasks are
renamed: updatePersistentStatus() becomes updatePersistentTaskState()
and now takes a PersistentTaskState as a parameter. The
Task.Status type as been changed to PersistentTaskState in all
places were it make sense (in persistent task customs in cluster
state and all other methods that deal with the state of an allocated
persistent task).
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.
For 6.3 we renamed the `tar` and `zip` distributions to `oss-tar` and
`oss-zip`. Then we added new `tar` and `zip` distributions that contain
x-pack and are licensed under the Elastic License. Unfortunately we
accidentally generated POM files along side the new `tar` and `zip`
distributions that incorrectly claimed that they were Apache 2 licensed.
Oooops.
This fixes the license on the POMs generated for the `tar` and `zip`
distributions.
This adds a `description` to ML filters in order
to allow users to describe their filters in a human
readable form which is also editable (filter updates
to be added shortly).
Due to a runtime classpath clash, featureAware task was failing on JVMs
higher than 1.8 (since the ASM version from Painless was used instead
which does not recognized Java 9 or 10 bytecode) causing the task to
fail.
This commit excludes the ASM dependency (since it's not used by SQL
itself).
We currently have a specific REST action to retrieve all aliaes, which
uses internally the get index API. This doesn't seem to be required
anymore though as the existing RestGetAliaesAction could as well take
the requests with no indices and aliases specified.
This commit removes the RestGetAllAliasesAction in favour of using
RestGetAliasesAction also for requests that don't specify indices nor
aliases. Similar to #31129.
x-pack/sql depends on lang-painless which depends on ASM 5.1
FeatureAwareCheck needs ASM 6
This is a hack to strip ASM5 from the classpath for FeatureAwareCheck
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.
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.
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.

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

Post and Put requests always have a body.
Closes#30057
Allows users of the Low Level REST client to specify which hosts a
request should be run on. They implement the `NodeSelector` interface
or reuse a built in selector like `NOT_MASTER_ONLY` to chose which nodes
are valid. Using it looks like:
```
Request request = new Request("POST", "/foo/_search");
RequestOptions options = request.getOptions().toBuilder();
options.setNodeSelector(NodeSelector.NOT_MASTER_ONLY);
request.setOptions(options);
...
```
This introduces a new `Node` object which contains a `HttpHost` and the
metadata about the host. At this point that metadata is just `version`
and `roles` but I plan to add node attributes in a followup. The
canonical way to **get** this metadata is to use the `Sniffer` to pull
the information from the Elasticsearch cluster.
I've marked this as "breaking-java" because it breaks custom
implementations of `HostsSniffer` by renaming the interface to
`NodesSniffer` and by changing it from returning a `List<HttpHost>` to a
`List<Node>`. It *shouldn't* break anyone else though.
Because we expect to find it useful, this also implements `host_selector`
support to `do` statements in the yaml tests. Using it looks a little
like:
```
---
"example test":
- skip:
features: host_selector
- do:
host_selector:
version: " - 7.0.0" # same syntax as skip
apiname:
something: true
```
The `do` section parses the `version` string into a host selector that
uses the same version comparison logic as the `skip` section. When the
`do` section is executed it passed the off to the `RestClient`, using
the `ElasticsearchHostsSniffer` to sniff the required metadata.
The idea is to use this in mixed version tests to target a specific
version of Elasticsearch so we can be sure about the deprecation
logging though we don't currently have any examples that need it. We do,
however, have at least one open pull request that requires something
like this to properly test it.
Closes#21888
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.
The core REST tests with security currently use a hardcoded username and
password. This is not amenable to running these tests in scenarios where
the user controls the creation of the cluster and owns the credentials
for this cluster. This commit enables running the core REST tests with
security with a custom username and password.
The goal of this commit is to address unknown licenses when producing
the dependencies info report. We have two different checks that we run
on licenses. The first check is whether or not we have stashed a copy of
the license text for a dependency in the repository. The second is to
map every dependency to a license type (e.g., BSD 3-clause). The problem
here is that the way we were handling licenses in the second check
differs from how we handle licenses in the first check. The first check
works by finding a license file with the name of the artifact followed
by the text -LICENSE.txt. Yet in some cases we allow mapping an artifact
name to another name used to check for the license (e.g., we map
lucene-.* to lucene, and opensaml-.* to shibboleth. The second check
understood the first way of looking for a license file but not the
second way. So in this commit we teach the second check about the
mappings from artifact names to license names. We do this by copying the
configuration from the dependencyLicenses task to the dependenciesInfo
task and then reusing the code from the first check in the second
check. There were some other challenges here though. For example,
dependenciesInfo was checking too many dependencies. For now, we should
only be checking direct dependencies and leaving transitive dependencies
from another org.elasticsearch artifact to that artifact (we want to do
this differently in a follow-up). We also want to disable
dependenciesInfo for projects that we do not publish, users only care
about licenses they might be exposed to if they use our assembled
products. With all of the changes in this commit we have eliminated all
unknown licenses. A follow-up will enforce that when we add a new
dependency it does not get mapped to unknown, these will be forbidden in
the future. Therefore, with this change and earlier changes are left
having no unknown licenses and two custom licenses; custom here means it
does not map to an SPDX license type. Those two licenses are xz and
ldapsdk. A future change will not allow additional custom licenses
unless they are explicitly whitelisted. This ensures that if a new
dependency is added it is mapped to an SPDX license or mapped to custom
because it does not have an SPDX license.

Make SAML Response Destination check compliant
Only validate the Destination element of an incoming SAML Response
if Destination is present and the SAML Response is signed.
The standard [1] - 3.5.5.2 and [2] - 3.2.2 does mention that the
Destination element is optional and should only be verified when
the SAML Response is signed. Some Identity Provider implementations
are known to not set a Destination XML Attribute in their SAML
responses when those are not signed, so this change also aims to
enhance interoperability.

Use all running nodes as unicast seeds in the rolling restart tests to
avoid a race between pinging and the tests. Without this if the tests
are too fast then when a new node comes up and pings its single

running node.
This is related to #27260 and #28898. This commit adds the transport-nio

SSLTrustRestrictionsTests updates the restrictions YML file during the test run to change the set of restrictions. This update was small, but it wasn't atomic.
If the yml file is reloaded while empty or invalid, then it causes all SSL certificates to be considered invalid (until it is reloaded again), which could break the sniffing/administrative client that runs underneath the tests.
A previous refactoring of the CLI scripts migrated all of the CLI tools
to shell to a common script, elasticsearch-cli. This approach is fine in
Bash where it is easy to tear arguments apart but it doesn't work so
well on Windows where quoting is insane. To avoid having to tear the
arguments apart to separate the first argument to elasticsearch-cli from
the remaining arguments, we instead choose a strategy where we can avoid
tearing the arguments apart. To do this, we will instead pass the main
class by an environment variable and then we can pass the arguments
straight through. This will let us avoid awful quoting issues on
Windows. This is the Windows side of that effort and the Bash side was
in a previous commit.

This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
I pushed a test that `assertBusy`s for a whole hour accidentally. I was
testing something and forgot to revert my local hack but caught it on
backport. This removes it.
This is much more realistic and can find more issues. This causes the
"mixed cluster" tests to be run twice so I had to fix the tests to work
in that case. In most cases I did as little as possible to get them
working but in a few cases I went a little beyond that to make them
easier for me to debug while getting them to work. My test changes:
1. Remove the "basic indexing" tests and replace them with a copy of the
tests used in the OSS. We have no way of sharing code between these two
projects so for now I copy.
2. Skip the a few tests in the "one third" upgraded scenario:
* creating a scroll to be reused when the cluster is fully upgraded
* creating some ml data to be used when the cluster is fully ugpraded
3. Drop many "assert yellow and that the cluster has two nodes"
assertions. These assertions duplicate those made by the wait condition
and they fail now that we have three nodes.
4. Switch many "assert green and that the cluster has two nodes" to 3
nodes. These assertions are unique from the wait condition and, while
I imagine they aren't required in all cases, now is not the time to
find that out. Thus, I made them work.
5. Rework the index audit trail test so it is more obvious that it is
the same test expecting different numbers based on the shape of the
cluster. The conditions for which number are expected are fairly
complex because the index audit trail is shut down until the template
for it is upgraded and the template is upgraded when a master node is
elected that has the new version of the software.
6. Add some more information to debug the index audit trail test because
it helped me figure out what was going on.
I also dropped the `waitCondition` from the `rolling-upgrade-basic`
tests because it wasn't needed.
Closes#25336
The native realm's usage stats were previously pulled from the cache,
which only contains the number of users that had authenticated in the
past 20 minutes. This commit changes this so that we pull the current
value from the security index by executing a search request. In order
to support this, the usage stats for realms is now asynchronous so that
we do not block while waiting on the search to complete.
The Index Audit trail allows the override of the template index
settings with settings specified on the conf file.
A bug will manifest when such conf file settings are specified
for templates that need to be upgraded. The bug is an endless
upgrade loop because the upgrade, although successful, is
not reckoned as such by the upgrade service.

This commit adds a check that any class in X-Pack that is a feature
aware custom also implements the appropriate mix-in interface in
X-Pack. These interfaces provide a default implementation of
FeatureAware#getRequiredFeature that returns that x-pack is the required
feature. By implementing this interface, this gives a consistent way for
X-Pack feature aware customs to return the appopriate required feature
and this check enforces that all such feature aware customs return the
appropriate required feature.
We should not allow the user to configure index patterns that also match
the index which stores the rollup index.
For example, it is quite natural for a user to specify `metricbeat-*`
as the index pattern, and then store the rollups in `metricbeat-rolled`.
This will start throwing errors as soon as the rollup index is created
because the indexer will try to search it.
Note: this does not prevent the user from matching against existing
rollup indices. That should be prevented by the field-level validation
during job creation.
ObjectParser should throw XContentParseExceptions, not IAE. A dedicated parsing
exception can includes the place where the error occurred.

Extends ActionRequestValidationException with a rollup-specific version
to make it easier to handle mapping validation issues on the client
side.
The type will now be `rollup_action_request_validation_exception`
instead of `action_request_validation_exception`
The majority of Responses inheriting from AcknowledgeResponse implement
the readFrom and writeTo serialization method in the same way. Moving this
as a default into AcknowledgeResponse and letting the few exceptions that
need a slightly different implementation handle this themselves saves a lot
of duplication.
With #31020 we introduced the ability for transport clients to indicate what features they support
in order to make sure we don't serialize object to them they don't support. This PR adapts the
serialization logic of persistent tasks to be aware of those features and not serialize tasks that
aren't supported.
Also, a version check is added for the future where we may add new tasks implementations and
need to be able to indicate they shouldn't be serialized both to nodes and clients.
As the implementation relies on the interface of `PersistentTaskParams`, these are no longer
optional. That's acceptable as all current implementation have them and we plan to make
`PersistentTaskParams` more central in the future.

If you invoke elasticsearch-plugin (or any other CLI script on Windows)
with a path that has a percent-encoded space (or any other
percent-encoded character) because the CLI scripts now shell into a
common shell script (elasticsearch-cli) the percent-encoded space ends
up being interpreted as a parameter. For example passing install --batch
file:/c:/encoded%20%space/analysis-icu-7.0.0.zip to elasticsearch-plugin
leads to the %20 being interpreted as %2 followed by a zero. Here, the
%2 is interpreted as the second parameter (--batch) and the
InstallPluginCommand class ends up seeing
file:/c/encoded--batch0space/analysis-icu-7.0.0.zip as the path which
will not exist. This commit addresses this by escaping the %* that is
used to pass the parameters to the common CLI script so that the common
script sees the correct parameters without the %2 being substituted.
This commit introduces the ability for a client to communicate to the
server features that it can support and for these features to be used in
influencing the decisions that the server makes when communicating with
the client. To this end we carry the features from the client to the
underlying stream as we carry the version of the client today. This
enables us to enhance the logic where we make protocol decisions on the
basis of the version on the stream to also make protocol decisions on
the basis of the features on the stream. With such functionality, the
client can communicate to the server if it is a transport client, or if
it has, for example, X-Pack installed. This enables us to support
rolling upgrades from the OSS distribution to the default distribution
without breaking client connectivity as we can now elect to serialize
customs in the cluster state depending on whether or not the client
reports to us using the feature capabilities that it can under these
customs. This means that we would avoid sending a client pieces of the
cluster state that it can not understand. However, we want to take care
and always send the full cluster state during node-to-node communication
as otherwise we would end up with different understanding of what is in
the cluster state across nodes depending on which features they reported
to have. This is why when deciding whether or not to write out a custom
we always send the custom if the client is not a transport client and
otherwise do not send the custom if the client is transport client that
does not report to have the feature required by the custom.

Otherwise we could end up with persistent tasks metadata in the cluster that some of the nodes
might not understand in case where the cluster is during rolling upgrade from the default 6.2 to the
default 6.3 distribution.
Follow-up to #30743
In case an error is returned when calling search_shards on a remote
cluster, which will lead to throwing an exception in the coordinating
node, we should make sure that the status code returned by the
coordinating node is the same as the one returned by the remote
cluster. Up until now a 500 - Internal Server Error was always
returned. This commit changes this behaviour so that for instance if an
index is not found, which causes an 404, a 404 is also returned by the
coordinating node to the client.

This modifies the high level rest client to allow calling code to
customize per request options for the bulk API. You do the actual
customization by passing a `RequestOptions` object to the API call
which is set on the `Request` that is generated by the high level
client. It also makes the `RequestOptions` a thing in the low level
rest client. For now that just means you use it to customize the
headers and the `httpAsyncResponseConsumerFactory` and we'll add
node selectors and per request timeouts in a follow up.
I only implemented this on the bulk API because it is the first one
in the list alphabetically and I wanted to keep the change small
enough to review. I'll convert the remaining APIs in a followup.
* Ensure that a purposefully wrong key is used
Uses a specific keypair for tests that require a purposefully wrong
keypair instead of selecting one randomly from the same pull from
which the correct one is selected. Entropy is low because of the
small space and the same key can be randomly selected as both the
correct one and the wrong one, causing the tests to fail.
The purposefully wrong key is also used in
testSigningKeyIsReloadedForEachRequest and needs to be cleaned
up afterwards so the rest of the tests don't use that for signing.

This commit removes the RequestBuilder generic type from Action. It was

This commit reworks the Sniffer component to simplify it and make it possible to test it.
In particular, it no longer takes out the host that failed when sniffing on failure, but rather relies on whatever the cluster returns. This is the result of some valid comments from #27985. Taking out one single host is too naive, hard to test and debug.
A new Scheduler abstraction is introduced to abstract the tasks scheduling away and make it possible to plug in any test implementation and take out timing aspects when testing.
Concurrency aspects have also been improved, synchronized methods are no longer required. At the same time, we were able to take #27697 and #25701 into account and fix them, especially now that we can more easily add tests.
Last but not least, unit tests are added for the Sniffer component, long overdue.

This code is from an Apache 2.0 licensed codebase and when we imported
it into our codebase it carried the Apache 2.0 license as well. However,
during the migration of the X-Pack codebase from the internal private
repository to the elastic/elasticsearch repository, the migration tool
mistakently changed the license on this source file from the Apache 2.0
license to the Elastic license. This commit addresses this mistake by
reapplying the Apache 2.0 license.
Currently failures to compile a script usually lead to a ScriptException, which

ScriptException to return 400 (bad request) as status code.

This is a bug that was identified by the kibana team. Currently on a

serialization in the rest response.
Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps

This commit reworks the way our realms perform caching in order to
limit each principal to a single ongoing authentication per realm. In
other words, this means that multiple requests made by the same user
will not trigger more that one authentication attempt at a time if no
entry has been stored in the cache. If an entry is present in our
cache, there is no restriction on the number of concurrent
authentications performed for this user.
This change enables us to limit the load we place on an external system

expensive operations such as BCrypt authentication.

This commit fixes an issue with dynamic mapping updates when an index
operation is performed against an alias and when the user only has
permissions to the alias. Dynamic mapping updates resolve the concrete
index early to prevent issues so the information about the alias that
the triggering operation was being executed against is lost. When
security is enabled and a user only has privileges to the alias, this
dynamic mapping update would be rejected as it is executing against the
concrete index and not the alias. In order to handle this situation,
the security code needs to look at the concrete index and the
authorized indices of the user; if the concrete index is not authorized
the code will attempt to find an alias that the user has permissions to
update the mappings of.
Closes#30597
The .watcher-history-* template is currently using a plugin-custom index setting xpack.watcher.template.version,
which prevents this template from being installed in a mixed OSS / X-Pack cluster, ultimately
leading to the situation where an X-Pack node is constantly spamming an OSS master with (failed)
template updates. Other X-Pack templates (e.g. security-index-template or security_audit_log)
achieve the same versioning functionality by using a custom _meta field in the mapping instead.
This commit switches the .watcher-history-* template to use the _meta field instead.
Persistent tasks was moved from X-Pack to core in #28455.

Enables a rolling restart from the OSS distribution to the x-pack based distribution by preventing
x-pack code from installing custom metadata into the cluster state until all nodes are capable of
deserializing this metadata.

settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.

This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.
Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.

This change is to support rolling upgrade from a pre-6.3 default
distribution (i.e. without X-Pack) to a 6.3+ default distribution
(i.e. with X-Pack).
The ML metadata is no longer eagerly added to the cluster state
as soon as the master node has X-Pack available. Instead, it
is added when the first ML job is created.
As a result all methods that get the ML metadata need to be able
to handle the situation where there is no ML metadata in the
current cluster state. They do this by behaving as though an
empty ML metadata was present. This logic is encapsulated by
always asking for the current ML metadata using a static method
on the MlMetadata class.

When the encrpytion of sensitive date is enabled, test that a
scheduled watch is executed as expected and produces the correct value
from a secret in the basic auth header.
Make SSLContext reloadable
This commit replaces all customKeyManagers and TrustManagers
(ReloadableKeyManager,ReloadableTrustManager,
EmptyKeyManager, EmptyTrustManager) with instances of
X509ExtendedKeyManager and X509ExtendedTrustManager.
This change was triggered by the effort to allow Elasticsearch to
run in a FIPS-140 environment. In JVMs running in FIPS approved
mode, only SunJSSE TrustManagers and KeyManagers can be used.
Reloadability is now ensured by a volatile instance of SSLContext
in SSLContectHolder.
SSLConfigurationReloaderTests use the reloadable SSLContext to
initialize HTTP Clients and Servers and use these for testing the
key material and trust relations.
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
This commit exposes the master version to the REST test context. This
will be needed in a follow-up where the master version will be used to
determine whether or not a certain warning header is expected.
Due to the way composite aggregation works, ordering in GROUP BY can be
applied only through grouped columns which now the analyzer verifier
enforces.
Fix 29900
This commit removes the SecurityLifecycleService, relegating its former
functions of listening for cluster state updates to SecurityIndexManager
and IndexAuditTrail.
This change adds a grok_pattern field to the GET categories API
output in ML. It's calculated using the regex and examples in the
categorization result, and applying a list of candidate Grok
patterns to the bits in between the tokens that are considered to
define the category.
This can currently be considered a prototype, as the Grok patterns
it produces are not optimal. However, enough people have said it
would be useful for it to be worthwhile exposing it as experimental
functionality for interested parties to try out.
This is fixing an issue that has come up in some builds. In some
scenarios I see an assertion failure that we are trying to move to
application mode when we are not in handshake mode. What I think is
happening is that we are in handshake mode and have received the
completed handshake message AND an application message. While reading in
handshake mode we switch to application mode. However, there is still
data to be consumed so we attempt to continue to read in handshake mode.
This leads to us attempting to move to application mode again throwing
an assertion.
This commit fixes this by immediatly exiting the handshake mode read
method if we are not longer in handshake mode. Additionally if we swap
modes during a read we attempt to read with the new mode to see if there
is data that needs to be handled.
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The errors were caused because release tests would use a copy of
the public key that was formatted differently. The change to the
public key format was introduced in [1].
Release tests Jenkins job has now been updated to use the correct
key format depending on the branch they run on [2]

This commit adds the ability to specify a plugin from maven for a
test cluster to use. Currently, only local projects may be used as
plugins, except when testing bwc, where the coordinates of the project
are used. However, that assumes all projects always keep the same
coordinates, or are even still plugins, which is no longer the case for
x-pack. The full cluster and rolling restart tests are changed to use
this new method when pulling x-pack versions before 6.3.0.
Modifies the SQL tests to use the new `Request` object flavored methods
introduced onto the `RestClient` in #29623. We'd like to remove the old
methods eventually so we should stop using them.
Since adding back the per-watch statistics, we do not need to access
every trigger engine implementation to get the current total job count.
This commit removes the unused methods to do so.

This commit cleans up some code in the FileUserPasswdStore and the
FileUserRolesStore classes. The maps used in these classes are volatile
so we need to make sure that we don't perform multiple operations with
the map unless we are sure we are using a reference to the same map.
The maps are also never null, but there were a few null checks in the
code that were not needed. These checks have been removed.
The TokenMetaData equals method compared byte arrays using `.equals` on
the arrays themselves, which is the equivalent of an `==` check. This
means that a seperate byte[] with the same contents would not be
considered equivalent to the existing one, even though it should be.
The method has been updated to use `Array#equals` and similarly the
hashcode method has been updated to call `Arrays#hashCode` instead of
calling hashcode on the array itself.
These tests are both in the file `watcher/stats/10_basic`, and have been
failing fairly frequently over the last month with a start-up issue.
The issue is being tracked in #30298.
Dates internally contain milliseconds (which appear when converting them
to Strings) however parsing does not accept them (and is being strict).
The parser has been changed so that Date is mandatory but the time
(including its fractions such as millis) are optional.
Fix#30002
This commit adds a general state listener to the SecurityIndexManager,
and replaces the existing health and up-to-date listeners with that. It
also moves helper methods relating to health to SecurityIndexManager
from SecurityLifecycleService.
This commit moves the generated-resources directory to be within
the build directory for the openldap-tests and saml-idp-tests
projects. Both projects create a generated-resources directory that
should have been in the build directory but were instead at the same
level as the build directory.
As conformance to best practices, this changes ensures that if a
SAML Response is signed, we verify the signature before processing
it any further. We were only checking the InResponseTo and
Destination attributes before potential signature validation but
there was no reason to do that up front either.
With the opening of xpack, we still retained a run task within
:x-pack:plugin. However, the root level run task also runs with the
default distribution. This change removes the extra run task inside
xpack in favor of using the root level task, and moves the
license/configuration code for run into the main run configuration.
This commit removes the hardcoded list of unconfigured ciphers in the
SslIntegrationTests. This list may include ciphers that are not
supported on certain JVMs. This list is replaced with code that
dynamically computes the set of ciphers that are not configured for
use by default.
The HTTPClient used in watcher is based on the apache http client. The
current client is using a lot of defaults - which are not always
optimal. Two of those defaults are the maximum number of total
connections and the maximum number of connections to a single route.
If one of those limits is reached, the HTTPClient waits for a connection
to be finished thus acting in a blocking fashion. In order to prevent
this when many requests are being executed, we increase the limit of
total connections as well as the connections per route (a route is
basically an endpoint, which also contains proxy information, not
containing an URL, just hosts).
On top of that an additional option has been set to evict
long running connections, which can potentially be reused after some
time. As this requires an additional background thread, this required
some changes to ensure that the httpclient is closed properly. Also the
timeout for this can be configured.
This commit renames IndexLifecycleManager to SecurityIndexManager as it
is not actually a general purpose class, but specific to security. It
also removes indirection in code calling the lifecycle service, instead
calling the security index manager directly.
Starting watcher should wait for the watcher to be started before
marking the status as started, which is now done via a callback.
Also, reloading watcher could set the execution service to paused. This could
lead to watches not being executed, when run in tests. This fix does not
change the paused flag in the execution service, just clears out the
current queue and executions.
Closes#30381
Today when processing a request for a URL path for which we can not find
a handler we send back a plain-text response. Yet, we have the accept
header in our hand and can respect the accepted media type of the
request. This commit addresses this.
This commit removes the unnecessary transport_client cluster permission
from the role that is used as an example in our documentation. This
permission is not needed to use cross cluster search.
When validating the search request, we make sure any date_histogram
aggregations have timezones that match the jobs. But we didn't
do any such validation on range queries.
While it wouldn't produce incorrect results, it would be confusing
to the user as no documents would match the aggregation (because we
add a filter clause on the timezone for the agg).
Now the user gets an exception up front, and some helpful text about
why the range query didnt match, and which timezones are acceptable
This commit updates the multi cluster search test with security so that
the user that is simply performing a multi cluster search does not have
any cluster permissions. This is done as none are needed by this user
and excess privileges could mask a behavior change.
Upgrade to lucene-7.4.0-snapshot-1ed95c097b
This version contains:
* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.
* A new API to retrieve matches (offsets and positions) of a query for a single document.
* Support for soft deletes in the index writer.
* A fixed shingle filter that handles index time synonyms.
* Support for emoji sequence in ICUTokenizer (with an upgrade to icu 61.1)
When the watcher service pauses execution due to a cluster state update,
the trigger service and its engines also need to pause properly instead
of keeping going. This is also important when the .watches index is
deleted, so that watches don't stay in a triggered mode.
The IndexAndAliasesResolver resolves the indices and aliases for each
request and also handles local and remote indices. The current
implementation uses the ResolvedIndices class to hold the resolved
indices and aliases. While evaluating the indices and aliases against
the user's permissions, the final value for ResolvedIndices is
constructed. Prior to this change, this was done by creating a
ResolvedIndices for the first set of indices and for each additional
addition, a new ResolvedIndices object is created and merged with
the existing one. With a small number of indices and aliases this does
not pose a large problem; however as the number of indices/aliases
grows more list allocations and array copies are needed resulting in a
large amount of garbage and severely impacted performance.
This change introduces a builder for ResolvedIndices that appends to
mutable lists until the final value has been constructed, which will
ultimately reduce the amount of garbage generated by this code.
QA tests that use security need to use a trial license instead of a
basic license. Basic licenses do not enable security so these tests are
not running in the expected configuration. This can also lead to issues
that seem completely unrelated such as authentication failures right
after cluster formation.
The authentication failure right after cluster formation happens since
a request makes it past the authentication license checks and the
request starts the authentication process. During authentication the
cluster forms and the license is updated to a basic license, which
disables all realms. The request that is being authenticated then tries
to iterate over the realms, but the realms are empty and the request
cannot be authenticated. This results in a authentication failure even
though the credentials provided are correct.
Closes#30306
When dealing with filtering, a composite aggregation might return empty
buckets (which have been filtered) which gets sent as is to the client.
Unfortunately this interprets the response as no more data instead of
retrying.
This now has changed and the listener keeps retrying until either the
query has ended or data passes the filter.
Fix#30292
This commit fixes an issue with the data diagnostics were
empty buckets are not reported even though they should. Once
a job is reopened, the diagnostics do not get initialized from
the current data counts (especially the latest record timestamp).
The result is that if the data that is sent have a time gap compared
to the previous ones, that gap is not accounted for in the empty bucket
count.
This commit fixes that by initializing the diagnostics with the current
data counts.
Closes#30080
Each test now has its own watch id that is being used.
This ensures there are no old history entries, which can potentially
lead to broken test assertions.
The current implementation starts/stops watcher using an executor. This
can result in our of order operations.
This commit reduces those executor calls to an absolute minimum in order
to be able to do state changes within the cluster state listener method,
which runs in sequence.
When a state change occurs that forces the watcher service to pause
(like no watcher index, no master node, no local shards), the service is
now in a paused state.
Pausing is a super lightweight operation, which marks the
ExecutionService as paused and waits for the currently executing watches
to finish in the background via an executor. The same applies for
stopping, the potentially long running operation is outsourced in to an
executor, as waiting for executed watches is decoupled from the current
state.
The only other long running operation is starting, where watches need to
be loaded. This is also done via an executor, but has an additional
protection by checking the cluster state version it was started with. If
another cluster state version was trying to load the watches, then this
loading will not take effect.
This PR also cleans up some unused states, like the a simple boolean in
the HistoryStore/TriggeredWatchStore marking it as started or stopped,
as this can now be caught in the execution service.
Another advantage of this approach is the fact, that now only triggered
watches are not getting executed, while watches that are run via the
Execute Watch API will still be executed regardless if watcher is
stopped or not.
Lastly the TickerScheduleTriggerEngine thread now only starts on data nodes.
This commit is a follow up to #30135. It updates the stream
compatibility versions in the start_trial requests and responses to
reflect that fact that this work has been backported to 6.3.
Necessary changes so that the licensing functionality can be
used in a JVM in FIPS 140 approved mode.
* Uses adequate salt length in encryption
* Changes key derivation to PBKDF2WithHmacSHA512 from a custom
approach with SHA512 and manual key stretching
* Removes redundant manual padding
Other relevant changes:
* Uses the SAH512 hash instead of the encrypted key bytes as the
key fingerprint to be included in the license specification
* Removes the explicit verification check of the encryption key
as this is implicitly checked in signature verification.
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.

* SQL: Reduce number of ranges generated for comparisons
Rewrote optimization rule for combining ranges by improving the

them in a range, regardless of their place inside an expression.
Additionally, improve the comparisons of Numbers of different types
Also, improve reassembly of conjunction/disjunction into balanced
trees.
Do not promote BinaryComparisons to Ranges since it introduces NULL
boundaries and thus a corner-case that needs too much handling

Fix#30017
Many tests are added with a version check so that they do not run against a
version that doesn't have the feature yet. Master is 7.0, so all tests that
do not run against 6.0+ can be removed and the version check can be removed
on all tests that always run on 6.0+.
The elasticsearch-users utility had various messages that were
outdated or incorrect. This commit updates the output from this
command to reflect current terminology and configuration.
The variadic constructor was only used in a few places and the
RepositoriesMetaData class is backed by a List anyway, so just using a
List will make it simpler to instantiate it.
This commit increases the logging for authentication in the x-pack
multi-node qa test project. This is needed to assist in debugging HTTP
authorization failures in waiting for the second node in these tests.
