This change adds a Fixture class for use by gradle. A Fixture is an
external process that integration tests will use. It can be added as a
dependsOn for integTest, and will automatically be shutdown upon success
or failure, as well as relevant information dumped on failure. There is
also an example fixture in this change.
This change removes the leftover pom files. A couple files were left for
reference, namely in qa tests that have not yet been migrated (vagrant
and multinode). The deb and rpm assemblies also still exist for
reference when finishing their setup in gradle.
See #13930
We moved a lot of repositories into elasticsearch, but in their new
location they retained their LICENSE.txt and NOTICE.txt files. These are
all the same, and having the license and notice and the root of the
repository should be sufficient.
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
As elasticsearch is marked as provided we don't need to explicitly exclude it from the assembly descriptor.
We get a warning today for all plugins, the following:
```
[INFO] --- maven-assembly-plugin:2.5.5:single (default) @ repository-s3 ---
[INFO] Reading assembly descriptor: /path/to/plugin-assembly.xml
[WARNING] The following patterns were never triggered in this artifact exclusion filter:
o 'org.elasticsearch:elasticsearch'
[INFO] Building zip: /path/to/target/releases/repository-s3-3.0.0-SNAPSHOT.zip
[INFO]
```
It now gives:
```
[INFO] --- maven-assembly-plugin:2.5.5:single (default) @ repository-s3 ---
[INFO] Reading assembly descriptor: /path/to/plugin-assembly.xml
[INFO] Building zip: /path/to/target/releases/repository-s3-3.0.0-SNAPSHOT.zip
[INFO]
```
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.
* Centralised plugin docs in docs/plugins/
* Moved integrations into same docs
* Moved community clients into the clients section of the docs
* Removed docs/community

the default classloader. It had all kinds of leniency in how the
classname was found, and simply cannot work with plugins having isolated
classloaders.
This change removes that method. Some of the uses of it were for custom
extension points, like custom repository or discovery types. A lot were
just there to plugin mock implementations for tests. For the settings
that were legitimate, all now support plugins adding the given setting
via onModule. For those that were specific to tests for mocks, they now
use Classes.loadClass (a helper around Class.forName). This is a
temporary measure until (in a future PR) tests can change the
implementation via package private statics.
I also removed a number of unnecessary intermediate modules, added a
"jvm-example" plugin that can be filled in in the future as a smoke test
for breaking plugins, and gave some documentation to "spawn" modules
interface.
