Martin Atkins	a1e29ae290	plugin/discovery: use go-version instead of semver The semver library we were using doesn't have support for a "pessimistic constraint" where e.g. the user wants to accept only minor or patch version upgrades. This is important for providers since users will generally want to pin their dependencies to not inadvertantly accept breaking changes. So here we switch to hashicorp's home-grown go-version library, which has the ~> constraint operator for this sort of constraint. Given how much the old version object was already intruding into the interface and creating dependency noise in callers, this also now wraps the "raw" go-version objects in package-local structs, thus keeping the details encapsulated and allowing callers to deal just with this package's own types.	9 years ago
Martin Atkins	9b4f15c261	plugin: move Client function into plugin, from plugin/discovery Having this as a method of PluginMeta felt most natural, but unfortunately that means that discovery must depend on plugin and plugin in turn depends on core Terraform, thus making the discovery package hard to use without creating dependency cycles. To resolve this, we invert the dependency and make the plugin package be responsible for instantiating clients given a meta, using a top-level function.	9 years ago
Martin Atkins	551bc9c4a4	plugin/discovery: build plugin clients These new methods ClientConfig and Client provide the bridge into the main plugin infrastructure by configuring and instantiating (respectively) a client object for the referenced plugin. This stops short of getting the proxy object from the client since that then requires referencing the interface for the plugin kind, which would then create a dependency on the main terraform package which we'd rather avoid here. It'll be the responsibility of the caller in the command package to do the final wiring to get a provider instance out of a provider plugin client.	9 years ago
Martin Atkins	0a08214a74	plugin/discovery: SHA256() method to get the hash of each plugin This will be used later to verify that installed plugins match what's available on the releases server.	9 years ago
Martin Atkins	39deb1ff6b	plugin/discovery: helpers for wrangling plugin versions With forthcoming support for versioned plugins we need to be able to answer questions like what versions of plugins are currently installed, what's the newest version of a given plugin available, etc. PluginMetaSet gives us a building block for this sort of plugin version wrangling.	9 years ago
