If the registry is unresponsive, you will now get an error
specific to this, rather than a misleading "provider unavailable" type
error. Also adds debug logging for when errors like this may occur
Terraform Registry (and other registry implementations) can now return
an array of warnings with the versions response. These warnings are now
displayed to the user during a `terraform init`.
This PR improves the error handling so we can provide better feedback about any service discovery errors that occured.
Additionally it adds logic to test for specific versions when discovering a service using `service.vN`. This will enable more informational errors which can indicate any version incompatibilities.
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.
By adding this method you now only have to pass a `*disco.Disco` object around in order to do discovery and use any configured credentials for the discovered hosts.
Of course you can also still pass around both a `*disco.Disco` and a `auth.CredentialsSource` object if there is a need or a reason for that!
Unlike the old installer in config/module, this uses new-style
installation directories that include the static module path so that paths
we show in diagnostics will be more meaningful to the user.
As before, we retrieve the entire "package" associated with the given
source string, rather than any given subdirectory directly, because the
retrieved module may contain ../ references into parent directories which
must be resolvable after extraction.
The level of abstraction that needs the "svchost" is the Module, not the
FriendlyHost. Us the new method in the module package for registry
interaction.
The detection of registry modules will have to happen in mutliple
phases. The go-getter interface requires that the detector return the
final URL, while we won't know that until we verify which version we
need. This leaves the regisry sources broken, to be re-integrated in a
following commit.
Removed some of the test cases that we don't allow in the svchost
package. Will check back if those are needed in the registry and work
around them as necessary.
