Martin Atkins	0e0e3d73af	core: New ResourceProvider methods for data resources This is a breaking change to the ResourceProvider interface that adds the new operations relating to data sources. DataSources, ValidateDataSource, ReadDataDiff and ReadDataApply are the data source equivalents of Resources, Validate, Diff and Apply (respectively) for managed resources. The diff/apply model seems at first glance a rather strange workflow for read-only resources, but implementing data resources in this way allows them to fit cleanly into the standard plan/apply lifecycle in cases where the configuration contains computed arguments and thus the read must be deferred until apply time. Along with breaking the interface, we also fix up the plugin client/server and helper/schema implementations of it, which are all of the callers used when provider plugins use helper/schema. This would be a breaking change for any provider plugin that directly implements the provider interface, but no known plugins do this and it is not recommended. At the helper/schema layer the implementer sees ReadDataApply as a "Read", as opposed to "Create" or "Update" as in the managed resource Apply implementation. The planning mechanics are handled entirely within helper/schema, so that complexity is hidden from the provider implementation itself.	10 years ago

Mitchell Hashimoto	84214437b3	Use hashicorp/go-plugin for plugin system This replaces this plugin system with the extracted hashicorp/go-plugin library. This doesn't introduce any new features such as binary flattening but opens us up to that a lot more easily and removes a lot of code from TF in favor of the upstream lib. This will introduce a protocol change that will cause all existing plugins to have to be recompiled to work properly. There is no actual API changes so they just have to recompile, but it is technically backwards incompatible.	10 years ago
