The @IndexSettings annoationat has been used to differentiate between node-level
and index level settings. It was also decoupled from realtime-updates such that
the settings object that a class got injected when it was created was static and
not subject to change when an update was applied. This change removes the annoation
and replaces it with a full-fledged class that adds type-safety and encapsulates additional
functionality as well as checks on the settings.
Plugin tests require having rest-api tests, and currently copy that spec
from a directory in the root of the plugin source into the test
resources. This change moves the rest-api-spec dir into test resources
so it is like any other test resources. It also removes unnecessary
configuration for resources from the shared plugin pom.
When running a RestIT test from the IDE, you actually start an internal node which does not automatically load the plugin you would like to test.
We need to add:
```java
@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
return pluginList(PLUGIN_HERE.class);
}
```
Everything works fine when running from maven because each test basically:
* installs elasticsearch
* installs one plugin
* starts elasticsearch with this plugin loaded
* runs the test
Note that this PR only fixes the fact we run an internal cluster with the expected plugin.
Cloud tests will still fail when run from the IDE because is such a case you actually start an internal node with many mock plugins.
And REST test suite for cloud plugins basically checks if the plugin is running by checking the output of NodesInfo API.
And we check:
```yml
- match: { nodes.$master.plugins.0.name: cloud-azure }
- match: { nodes.$master.plugins.0.jvm: true }
```
But in that case, this condition is certainly false as we started also `mock-transport-service`, `mock-index-store`, `mock-engine-factory`, `node-mocks`, `asserting-local-transport`, `mock-search-service`.
Closes#13479
The setting `plugin.types` is currently used to load plugins from the
classpath. This is necessary in tests, as well as the transport client.
This change removes the setting, and replaces it with the ability to
directly add plugins when building a transport client, as well as
infrastructure in the integration tests to specify which plugin classes
should be loaded on each node.
In plugins, we are using non consistent naming. We use `elasticsearch-cloud-aws` as the artifactId, which generates a jar file called `elasticsearch-cloud-aws-VERSION.jar`.
But when you want to install the plugin, you will end up with a shorter name for the plugin `cloud-aws`.
```
bin/plugin install cloud-aws
```
This commit changes that and use consistent names for `artifactId`, so `finalName`.
Also changed maven names.
The Plugin interface currently contains 6 different methods for
adding modules. Elasticsearch has 3 different levels of injectors,
and for each of those, there are two methods. The first takes no
arguments and returns a collection of class objects to construct. The
second takes a Settings object and returns a collection of module
objects already constructed. The settings argument is unecessary because
the plugin can already get the settings from its constructor. Removing
that, the only difference between the two versions is returning an
already constructed Module, or a module Class, and there is no reason
the plugin can't construct all their modules themselves.
This change reduces the plugin api down to just 3 methods for adding
modules. Each returns a Collection<Module>. It also removes the
processModule method, which was unnecessary since onModule
implementations fullfill the same requirement. And finally, it renames
the modules() method to nodeModules() so it is clear these are created
once for each node.
Moved the license checker config into the parent pom, and overrede
the license dir/target-to-check in distributions/pom.
Disabled the license checker explicitly for projects which run integration
tests but have no licenses dir:
* core
* distribution
* qa
* plugins/delete-by-query
* plugins/mapper-size
* plugins/site-example
Closes#12752Closes#12754
This is one of our esoteric metadata mappers so I think we should distribute
it in a plugin rather than in elasticsearch core.
This introduces one limitation: the value of the `_size` parameter is not
retrievable for documents that are only in the transaction log.
