Instead of get, set and remove we do get, remove and then set to avoid type conflicts in IngestDocument.
If the set still fails we try to restore the original field in ingest document.
Closes#19892
* rethrow script compilation exceptions into ingest configuration exceptions
* update readProcessor to rethrow any exception as an ElasticsearchException
Also introduced a `Processor.Parameters` class that is holder for several services processors rely on,
the IngestPlugin#getProcessors(...) method has been changed to accept `Processor.Parameters` instead
of each service seperately.
The factory for ingest processor is generic, but that is only for the
return type of the create mehtod. However, the actual consumer of the
factories only cares about Processor, so generics are not needed.
This change removes the generic type from the factory. It also removes
AbstractProcessorFactory which only existed in order pull the optional
tag from config. This functionality is moved to the caller of the
factories in ConfigurationUtil, and the create method now takes the tag.
This allows the covariant return of the implementation to work with
tests not needing casts.
Stored scripts are pulled from the cluster state, and the current api
requires passing the ClusterState on each call to compile. However, this
means every user of the ScriptService needs to depend on the
ClusterService. Instead, this change makes the ScriptService a
ClusterStateListener. It also simplifies tests a lot, as they no longer
need to create fake cluster states (except when testing stored scripts).
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.
Folded grok processor into ingest-common module.
The rest tests have been moved to ingest-common module as well, because these tests don't run in the rest-api-spec module but in the distribution:integ-test-zip module
and adding a test plugin there felt just wrong to me. I think this is ok. I left a tiny ingest rest test behind in that tests with an empty pipeline.
Removed messy tests, these tests were already covered in the rest tests
Added ingest test plugin in test infra so that each module testing integration with ingest doesn't need write its own plugin
Moved reindex ingest tests to qa module
