James Bardin	ec99b6910b	remove "~> 0.0" constraint suggestions ... Don't suggest constraints when the available plugin isn't versioned. Add zero version const for comparisons.	9 years ago
Martin Atkins	e3401947a6	plugin/discovery: PluginRequirements can specify SHA256 digests ... As well as constraining plugins by version number, we also want to be able to pin plugins to use specific executables so that we can detect drift in available plugins between commands. This commit allows such requirements to be specified, but doesn't yet specify any such requirements, nor validate them.	9 years ago
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	bcd395e6bd	plugin/discovery: Allow overriding the paths of certain plugin names ... The .terraformrc file allows the user to override the executable location for certain plugins. This mechanism allows us to retain that behavior for a deprecation period by treating such executables as an unversioned plugin for the given name and excluding all other candidates for that name, thus ensuring that the override will "win". Users must eventually transition away from using this mechanism and use vendor directories instead, because these unversioned overrides will never match for a provider referenced with non-zero version constraints.	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
