We need to limit the search request aggregations to whole multiples
of the configured interval for both histogram and date_histogram.
Otherwise, agg buckets won't overlap with the rolled up buckets
and the results will be incorrect.
For histogram, the validation is very simple: request must be >= the config,
and modulo evenly.
Dates are more tricky.
- If both request and config are fixed dates, we can convert to millis
and treat them just like the histo
- If both are calendar, we make sure the request is >= the config with
a static lookup map that ranks the calendar values relatively. All
calendar units are "singles", so they are evenly divisible already
- We disallow any other combination (one fixed, one calendar, etc)
This commit removes the unused User class from the protocol project.
This class was originally moved into protocol in preparation for moving
more request and response classes, but given the change in direction
for the HLRC this is no longer needed. Additionally, this change also
changes the package name for the User object in x-pack/plugin/core to
its original name.
This change adds support for the client credentials grant type to the
token api. The client credentials grant allows for a client to
authenticate with the authorization server and obtain a token to access
as itself. Per RFC 6749, a refresh token should not be included with
the access token and as such a refresh token is not issued when the
client credentials grant is used.
The addition of the client credentials grant will allow users
authenticated with mechanisms such as kerberos or PKI to obtain a token
that can be used for subsequent access.

In #29623 we added `Request` object flavored requests to the low level

This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```

This commit moves the ML QA tests to be a sub-project of ML. The purpose
of this refactoring is to enable ML developers to run
:x-pack:plugin:ml:check and run the vast majority of a ML tests with a
single command (this still does not contain the ML REST tests, nor the
upgrade tests). This simplifies local development for faster iteration.
There are two problems with the scheduler engine today. Both relate to
listeners that throw.
The first problem is that any triggered listener that throws a plain old
exception will cause no additional listeners to be triggered for the
event, and will also cause the scheduler to never be invoked again. This
leads to lost events and is bad.
The second problem is that any triggered listener that throws an error
of the fatal kind will not lead to that error because caught by the
uncaught exception handler. This is because the triggered listener is
executed as a future task under a scheduled thread pool executor. A
throwable there goes caught by the JDK framework and set as the outcome
on the future task. Since we never inspect these tasks for their
outcomes, nor is there a good place to do this, we have to handle these
errors ourselves. To do this, we catch them and dispatch them to the
uncaught exception handler via a forked thread. This is similar to our
handling in Netty.
As the multibucket feature was merged in, this test hit a side effect
which means buckets trailing an anomaly could become anomalous.
This commit fixes the problem by filtering low score records when
we request them.
Elasticsearch versions earlier than 6.4.0 cannot properly run in a
FIPS 140 JVM. This commit ensures that we use a non-FIPS JVM for
nodes that we spin up in BWC tests even when we're testing FIPS.

This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
We only upgrade the ID when the state is saved in one of four scenarios:
- when we reach a checkpoint (every 50 pages)
- when we run out of data
- when explicitly stopped
- on failure
The test was relying on the pre-upgrade to finish, save state and then
the post-upgrade to start, hit the end of data and upgrade ID. THEN
get the new doc and apply the new ID.
But I think this is vulnerable to timing issues. If the pre-upgrade
portion shutdown before it saved the state, when restarting we would run
through all the data from the beginning with the old ID, meaning both
docs would still have the old scheme.
This change makes the pre-upgrade wait for the job to go back to STARTED
so that we know it persisted the end point. Post-upgrade, it stops and
restarts the job to ensure the state was persisted and the ID upgraded.
That _should_ rule out the above timing issue.

Bumping down the version to 6.4 since the backport is complete. Also

Previously, we were using a simple CRC32 for the IDs of rollup documents.
This is a very poor choice however, since 32bit IDs leads to collisions
between documents very quickly.
This commit moves Rollups over to a 128bit ID. The ID is a concatenation
of all the keys in the document (similar to the rolling CRC before),
hashed with 128bit Murmur3, then base64 encoded. Finally, the job
ID and a delimiter (`$`) are prepended to the ID.
This gurantees that there are 128bits per-job. 128bits should
essentially remove all chances of collisions, and the prepended
job ID means that _if_ there is a collision, it stays "within"
the job.
BWC notes:
We can only upgrade the ID scheme after we know there has been a good
checkpoint during indexing. We don't rely on a STARTED/STOPPED
status since we can't guarantee that resulted from a real checkpoint,
or other state. So we only upgrade the ID after we have reached
a checkpoint state during an active index run, and only after the
checkpoint has been confirmed.
Once a job has been upgraded and checkpointed, the version increments
and the new ID is used in the future. All new jobs use the
new ID from the start
These tests ensure, that the basic watch APIs are tested in the rolling
upgrade tests. After initially adding a watch, the tests try to get,
execute, deactivate and activate a watch. Watcher stats are tested as
well, and an own java based test has been added for restarting, as that
requires waiting for a state change. Watcher history is also checked.
Closes#31216
The User class has been moved to the protocol project for upcoming work
to add more security APIs to the high level rest client. As part of
this change, the toString method no longer uses a custom output method
from MetadataUtils and instead just relies on Java's toString
implementation.
Added support for string manipulating functions with more than one parameter:
CONCAT, LEFT, RIGHT, REPEAT, POSITION, LOCATE, REPLACE, SUBSTRING, INSERT
This change updates KerberosAuthenticationIT to resolve the host used
to connect to the test cluster. This is needed because the host could
be an IP address but SPNEGO requires a hostname to work properly. This
is done by adding a hook in ESRestTestCase for building the HttpHost
from the host and port.
Additionally, the project now specifies the IPv4 loopback address as
the http host. This is done because we need to be able to resolve the
address used for the HTTP transport before the node starts up, but the
http.ports file is not written until the node is started.

This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.
Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.
Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.
Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.
This commit adds support for Kerberos authentication with a platinum
license. Kerberos authentication support relies on SPNEGO, which is
triggered by challenging clients with a 401 response with the
`WWW-Authenticate: Negotiate` header. A SPNEGO client will then provide
a Kerberos ticket in the `Authorization` header. The tickets are
validated using Java's built-in GSS support. The JVM uses a vm wide
configuration for Kerberos, so there can be only one Kerberos realm.
This is enforced by a bootstrap check that also enforces the existence
of the keytab file.
In many cases a fallback authentication mechanism is needed when SPNEGO
authentication is not available. In order to support this, the
DefaultAuthenticationFailureHandler now takes a list of failure response
headers. For example, one realm can provide a
`WWW-Authenticate: Negotiate` header as its default and another could
provide `WWW-Authenticate: Basic` to indicate to the client that basic
authentication can be used in place of SPNEGO.
In order to test Kerberos, unit tests are run against an in-memory KDC
that is backed by an in-memory ldap server. A QA project has also been
added to test against an actual KDC, which is provided by the krb5kdc
fixture.

* Complete changes for running IT in a fips JVM

The notion of "quality" is an overloaded term in the search ranking evaluation
context. Its usually used to decribe certain levels of "good" vs. "bad" of a
seach result with respect to the users information need. We currently report the
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.
* Remove BouncyCastle dependency from runtime
This commit introduces a new gradle project that contains
the classes that have a dependency on BouncyCastle. For
the default distribution, It builds a jar from those and
in puts it in a subdirectory of lib
(/tools/security-cli) along with the BouncyCastle jars.
This directory is then passed in the
ES_ADDITIONAL_CLASSPATH_DIRECTORIES of the CLI tools
that use these classes.
BouncyCastle is removed as a runtime dependency (remains
as a compileOnly one) from x-pack core and x-pack security.
Resolving wildcards in aliases expression is challenging as we may end
up with no aliases to replace the original expression with, but if we
replace with an empty array that means _all which is quite the opposite.
Now that we support and serialize the original requested aliases,
whenever aliases are replaced we will be able to know what was
initially requested. `MetaData#findAliases` can then be updated to not
return anything in case it gets empty aliases, but the original aliases
were not empty. That means that empty aliases are interpreted as _all
only if they were originally requested that way.
Relates to #31516
The rollup indexer uses a range query to select the next page
of results based on the last time bucket of the previous round
and the `delay` configured on the rollup job. This query uses
the `epoch_millis` format implicitly but doesn't set the `format`.
This result in errors during the rollup job if the field
definition doesn't allow this format. It can also miss documents
if the format is not accepted but another format in the field
definition is able to parse the query (e.g.: `epoch_second`).
This change ensures that we use `epoch_millis` as the only format
to parse the rollup range query.
* Detect and prevent configuration that triggers a Gradle bug

Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.

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).
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.
Added support for ASCII, BIT_LENGTH, CHAR, CHAR_LENGTH, LCASE, LENGTH, LTRIM, RTRIM, SPACE, UCASE functions.
Wherever Painless scripting is necessary (WHERE conditions, ORDER BY etc), those scripts are being used.
The test failure in #31916 revealed that updating
rules on a job was modifying the detectors list
in-place. That meant the old cluster state and the
updated cluster state had no difference and thus the
change was not propagated to non-master nodes.
This commit fixes that and also reviews all of ML
metadata in order to ensure immutability.

Merges the `query-builder-bwc` qa project into the
`full-cluster-restart` qa project, saving a cluster starts on every
build and *many* cluster starts on `./gradlew bwcTests`.
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.
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.
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 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).
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.
