While the code works perfectly well for a single segment, it returns the wrong values for multiple segments. E.g. If we have 500 docs in one segment and if we want to get the doc id = 280 then data.advanceExact(topDocs.scoreDocs[i].doc) works fine. If we have two segments, say, with first segment having docs 1-200 and the second segment having docs 201-500, then 280 is fetched from the second segment but is actually 480. Subtracting the docBase (280-200) takes us to the correct document which is 80 in the second segment and actually 280.
Test clusters currently has its own set of logic for dealing with
finding different versions of Elasticsearch, downloading them, and
extracting them. This commit converts testclusters to use the
DistributionDownloadPlugin.
This change adds the ability to attach annotative information for
classes, methods, fields, static methods, class bindings, and
instance bindings during Painless whitelisting.
Annotations are specified as @annotation or optionally as
@annotation[parameter="argument",...].
Annotations open up the ability to specify whitelist objects as
having a short name (no_import -> @no_import) or deprecated.
* introduce state to the REST API specification
* change state over to stability
* CCR is no GA updated to stable
* SQL is now GA so marked as stable
* Introduce `internal` as state for API's, marks stable in terms of lifetime but unstable in terms of guarantees on its output format since it exposes internal representations
* make setting a wrong stability value, or not setting it at all an error that causes the YAML test suite to fail
* update spec files to be explicit about their stability state
* Document the fact that stability needs to be defined
Otherwise the YAML test runner will fail (with a nice exception message)
* address check style violations
* update rest spec unit tests to include stability
* found one more test spec file not declaring stability, made sure stability appears after documentation everywhere
* cluster.state is stable, mark response in some way to denote its a key value format that can be changed during minors
* mark data frame API's as beta
* remove internal and private as states for an API
* removed the wrong enum values in the Stability Enum in the previous commit

Currently suggesters return null values on empty shards. Usually this gets replaced
by results from other non-epmty shards, but if the index is completely epmty (e.g. after
creation) the search responses "suggest" is also "null" and we don't render a corresponding
output in the REST response. This is an irritating edge case that requires special handling on
the user side (see #42473) and should be fixed.
This change makes sure every suggester type (completion, terms, phrase) returns at least an
empty skeleton suggestion output, even for empty shards. This way, even if we don't find
any suggestions anywhere, we still return and output the empty suggestion.
Closes#42473
testclusters detect from settings that security is enabled
if a user is not specified using the DSL introduced in this PR, a default one is created
the appropriate wait conditions are used authenticating with the first user defined in the DSL ( or the default user ).
an example DSL to create a user is user username:"test_user" password:"x-pack-test-password" role: "superuser" all keys are optional and default to the values shown in this example
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.
(cherry picked from commit 323f312bbc829a63056a79ebe45adced5099f6e6)
* Fix forking JVM runner
* Don't bump shadow plugin version
This commit adds a variant for every official distribution that omits
the bundled jdk. The "no-jdk" naming is conveyed through the package
classifier, alongside the platform. Package tests are also added for
each new distribution.
* Un-mute and fix BuildExamplePluginsIT
There doesn't seem to be anything wrong with the test iteself.
I think the failure were CI performance related, but while it was muted,
some failures managed to sneak in.

DfsPhase captures terms used for scoring a query in order to build global term statistics across
multiple shards for more accurate scoring. It currently does this by building the query's `Weight`
and calling `extractTerms` on it to collect terms, and then calling `IndexSearcher.termStatistics()`
for each collected term. This duplicates work, however, as the various `Weight` implementations
will already have collected these statistics at construction time.
This commit replaces this round-about way of collecting stats, instead using a delegating
IndexSearcher that collects the term contexts and statistics when `IndexSearcher.termStatistics()`
is called from the Weight.
It also fixes a bug when using rescorers, where a `QueryRescorer` would calculate distributed term
statistics, but ignore field statistics. `Rescorer.extractTerms` has been removed, and replaced with
a new method on `RescoreContext` that returns any queries used by the rescore implementation.
The delegating IndexSearcher then collects term contexts and statistics in the same way described
above for each Query.
For some users, the built in authorization mechanism does not fit their
needs and no feature that we offer would allow them to control the
authorization process to meet their needs. In order to support this,
a concept of an AuthorizationEngine is being introduced, which can be
provided using the security extension mechanism.
An AuthorizationEngine is responsible for making the authorization
decisions about a request. The engine is responsible for knowing how to
authorize and can be backed by whatever mechanism a user wants. The
default mechanism is one backed by roles to provide the authorization
decisions. The AuthorizationEngine will be called by the
AuthorizationService, which handles more of the internal workings that
apply in general to authorization within Elasticsearch.
In order to support external authorization services that would back an
authorization engine, the entire authorization process has become
asynchronous, which also includes all calls to the AuthorizationEngine.
The use of roles also leaked out of the AuthorizationService in our
existing code that is not specifically related to roles so this also
needed to be addressed. RequestInterceptor instances sometimes used a
role to ensure a user was not attempting to escalate their privileges.
Addressing this leakage of roles meant that the RequestInterceptor
execution needed to move within the AuthorizationService and that
AuthorizationEngines needed to support detection of whether a user has
more privileges on a name than another. The second area where roles
leaked to the user is in the handling of a few privilege APIs that
could be used to retrieve the user's privileges or ask if a user has
privileges to perform an action. To remove the leakage of roles from
these actions, the AuthorizationService and AuthorizationEngine gained
methods that enabled an AuthorizationEngine to return the response for
these APIs.
Ultimately this feature is the work included in:
#37785#37495#37328#36245#38137#38219Closes#32435
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.
The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.
The integ tests currently use the raw zip project name as the
distribution type. This commit simplifies this specification to be
"default" or "oss". Whether zip or tar is used should be an internal
implementation detail of the integ test setup, which can (in the future)
be platform specific.
We recently migrated suggestions to `Writeable`. That allows us to also
clean up empty constructors and methods that called them as they are no
longer needed. They are replaced by constructors that accept a
`StreamInput` instance.
Today, a setting can declare that its validity depends on the values of other
related settings. However, the validity of a setting is not always checked
against the correct values of its dependent settings because those settings'
correct values may not be available when the validator runs.
This commit separates the validation of a settings updates into two phases,
with separate methods on the `Setting.Validator` interface. In the first phase
the setting's validity is checked in isolation, and in the second phase it is
checked again against the values of its related settings. Most settings only
use the first phase, and only the few settings with dependencies make use of
the second phase.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).
Relates #33028
The contains syntax was added in #30874 but the skips were not properly
put in place.
The java runner has the feature so the tests will run as part of the
build, but language clients will be able to support it at their own
pace.
This change adds instance bindings to Painless. This binding allows a whitelisted
method to be called on an instance instantiated prior to script compilation.
Whitelisting must be done in code as there is no practical way to instantiate a
useful instance from a text file (see the tests for an example). Since an
instance can be shared by multiple scripts, each method called must be
thread-safe.
We throw parsing exception when an unknown array is found, but we don't when an unknown top-level field is found. This commit makes sure that unsupported top-level fields are not ignored in a do section.
Closes#34651
This slightly reworks the expert script plugin example so it fits on the
page when the docs are rendered. The box in which it is rendered is not
very wide so it took a bit of twisting to make it readable.
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
Add tests for build-tools to make sure example plugins build stand-alone using it.
This will catch issues such as referencing files from the buildSrc directly, breaking external uses of build-tools.
Suggestion responses were previously serialized as streamables which
made writing suggesters in plugins with custom suggestion response types
impossible. This commit makes them serialized as named writeables and
provides a facility for registering a reader for suggestion responses
when registering a suggester.
This also makes Suggestion responses abstract, requiring a suggester
implementation to provide its own types. Suggesters which do not need
anything additional to what is defined in Suggest.Suggestion should
provide a minimal subclass.
The existing plugin suggester integration tests are removed and
replaced with an equivalent implementation as an example
plugin.
* remove left-over comment
* make sure of the property for plugins
* skip installing modules if these exist in the distribution
* Log the distrbution being ran
* Don't allow running with integ-tests-zip passed externally
* top level x-pack/qa can't run with oss distro
* 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
Many fixtures have similar code for writing the pid & ports files or
for handling HTTP requests. This commit adds an AbstractHttpFixture
class in the test framework that can be extended for specific testing purposes.
Added dedicated script contexts for:
* script function score
* script sorting
* terms_set query
Scripts for these contexts will either have a specific return value or
use scoring and therefor in the future will need their own scripting classes.

Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
This pull request replaces the jvm-example plugin (from the jvm/site plugins era) by two new plugins: a custom-settings that shows how to register and use custom settings (including secured settings) in a plugin, and rest-handler plugin that shows how to register a rest handler.
The two plugins now reside in the plugins/examples project. They can serve as sample plugins for users, a special attention has been put on documentation. The packaging tests have been adapted to use the custom-settings plugin.
This commit adds a gradle plugin to ease development of meta plugins.
Applying the plugin will generated the meta plugin properties based on
the es_meta_plugin configuration object, which includes name and
description. The plugins to include within the meta plugin are
configured through the `plugins` list. An integ test task is also
automatically added.
This commit adds a PainlessExtension which may be plugged in via SPI to
add additional classes, methods and members to the painless whitelist on
a per context basis. An example plugin adding and using a whitelist is
also added.
* This change makes sure that we don't detect a file path containing a ':' as
a maven coordinate (e.g.: `file:C:\path\to\zip`)
* restore test muted on master
This commit adds the ability to package multiple plugins in a single zip.
The zip file for a meta plugin must contains the following structure:
|____elasticsearch/
| |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory)
| |____ <plugin2> <-- The plugin files for plugin2
| |____ meta-plugin-descriptor.properties <-- example contents below
The meta plugin properties descriptor is mandatory and must contain the following properties:
description: simple summary of the meta plugin.
name: the meta plugin name
The installation process installs each plugin in a sub-folder inside the meta plugin directory.
The example above would create the following structure in the plugins directory:
|_____ plugins
| |____ <name_of_the_meta_plugin>
| | |____ meta-plugin-descriptor.properties
| | |____ <plugin1>
| | |____ <plugin2>
If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory.
|_____ config
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
|_____ bin
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin
cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).
It is also not possible to remove a sub-plugin inside a meta plugin, only full removal of the meta plugin is allowed.
Closes#27316
This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
This allows plugins to plug rescore implementations into
Elasticsearch. While this is a fairly expert thing to do I've
done my best to point folks to the QueryRescorer as one that at
least documents the tradeoffs that it makes. I've attempted to
limit the API surface area by removing `SearchContext` from the
exposed interface, instead exposing just the IndexSearcher and
`QueryShardContext`. I also tried to make some of the class names
more consistent and do some general cleanup while I was there.
I entertained the notion of moving the `QueryRescorer` to module.
After all, it'd be a wonderful test to prove that you can plug
rescore implementation into Elasticsearch if the only built in
rescore implementation is in the module. But I decided against it
because the new module would require a client jar and it'd require
moving some more things around. I think if we really want to do
it, we should do it as a followup.
I did, on the other hand, create an "example" rescore plugin which
should both be a nice example for anyone wanting to plug in their
own rescore implementation and servers as a good integration test
to make sure that you can indeed plug one in.
Closes#26208
Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.
Removes the `assemble` task from projects that are not published.
This should speed up `gradle assemble` by skipping projects that
don't need to be built. Which is useful because `gradle assemble`
is how we cut releases.
