plugin: Display version + source when initializing plugins 2017-08-15 19:29:13 +02:00
James Bardin 2b84e786e9 allow missing x-terraform-protocol-version
If the release site is missing the "x-terraform-protocol-version"
header, we should fetch the latest spec'ed release. Downloading the
wrong protocol version can't do any damage, and the version present is
more than likely compatible.

Martin Atkins 610fcb605e plugin/discovery: allow customizing the OS/arch for auto-install
Previously we forced only installing for the current GOOS and GOARCH. Now
we allow this to be optionally overridden, which allows building tools
that can, for example, populate a directory with plugins to run on a Linux
server while working on a Mac.

Martin Atkins af2111f24e plugin/discovery: sentinel error values for Get errors
Some errors from Get are essentially user error, so we want to be able to
recognize them and give the user good feedback on how to proceed.

Although sentinel values are not an ideal solution to this, it's something
reasonably simple we can do to get this done without lots of refactoring.

James Bardin 415d562d36 add signature verification
Fetch the SHA256SUMS file and verify it's signature before downloading
any plugins.

This embeds the hashicorp public key in the binary. If the publickey is
replaced, new releases will need to be cut anyway. A
--verify-plugin=false flag will be added to skip signature verification
in these cases.

Martin Atkins af4c82d151 plugin/discovery: Installer.PurgeUnused method
Given a map describing the chosen plugin for each provider name, this
method should purge any other plugins present in the local cache
directory.

Martin Atkins f753974bb3 plugin/discovery: Installer interface, and provider implementation
Previously we had a "getProvider" function type used to implement plugin
fetching. Here we replace that with an interface type, initially with
just a "Get" function.

For now this just simplifies the interface by allowing the target
directory and protocol version to be members of the struct rather than
passed as arguments.

A later change will extend this interface to also include a method to
purge unused plugins, so that upgrading frequently doesn't leave behind
a trail of unused executable files.

Last minute change to the location of the binaries

James Bardin dbbafbd43f clean up plugin fetching
We can filter the allowed versions and sort them before checking the
protocol version, that way we can just return the first one found
reducing network requests.

James Bardin 5f053a2e64 refactor GetProvider
Get provider needs to be provided with the plugin protocol version,
because it can't be imported here directly.

The plugin url types and methods were confusing; replace them with a few
functions to format the urls.

James Bardin 8ad67991a5 check protocol version on plugins
Verify that the plugin we're requesting has a compatible protocol
version.

James Bardin 46190590cb change []*Version to []Version
Versions are used as values, so don't keep them as pointers here

James Bardin 2749946f5c basic plugin getter
Add discovery.GetProviders to fetch plugins from the relases site.

This is an early version, with no tests, that only (probably) fetches
plugins from the default location. The URLs are still subject to change,
and since there are no plugin releases, it doesn't work at all yet.
