Justin Campbell 0574eadb62 plugin/discovery: Verify sig against HashiCorp key
https://github.com/hashicorp/terraform/pull/19389 introduced a change to
the provider GPG signature verification process, and removed the
hardcoded HashiCorp GPG key.

While the changes were intended and are still planned for a future
release, we should still be verifying all providers in the TF 0.12.0
release against the HashiCorp GPG key until a more robust key
verification procedure is in place.

Fixes https://github.com/hashicorp/terraform/issues/20527

Justin Campbell 495826444b plugin/discovery: Use GPG keys from Registry
When verifying the signature of the SHA256SUMS file, we have been
hardcoding HashiCorp's public GPG key and using it as the keyring.

Going forward, Terraform will get a list of valid public keys for a
provider from the Terraform Registry (registry.terraform.io), and use
them as the keyring for the openpgp verification func.

Kristin Laemmert ae015e0f75 plugin/discovery: add function to filter list of versions by those which
support the requested platform.

If the newest version of a provider which matches the version
constraints does not support the requested platform, filter the list of
available versions by platform support and try again.

James Bardin 6cb4e14cf8 Use pooled http client for fetching providers
While the TLS handshakes are a fairly small overhead compared to
downloading the providers, clients in some situation are failing to
complete the TLS handshake in a timely manner. It's unclear if this is
because of heavily constrained clients are stalling while doing the
major crpto operations, or the edge servers are throttling repeated
requests from the same IPs.

This should allow reusing the open TLS connection to the release edge
servers during init.

Martin Atkins 879899d434 plugin/discovery: plugin caching mechanism
For users that have metered or slow internet connections it is annoying
to have Terraform constantly re-downloading the same files when they
initialize many separate directories.

To help such users, here we add an opt-in mechanism to use a local
directory as a read-through cache. When enabled, any plugin download will
be skipped if a suitable file already exists in the cache directory. If
the desired plugin isn't in the cache, it will be downloaded into the
cache for use next time.

This mechanism also serves to reduce total disk usage by allowing
plugin files to be shared between many configurations, as long as the
target system isn't Windows and supports either hardlinks or symlinks.

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.

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 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.
