As the comment notes, this hostname is the default for provide source
addresses. We'll shortly be adding some address types to represent module
source addresses too, and so we'll also have DefaultModuleRegistryHost
for that situation.
(They'll actually both contain the the same hostname, but that's a
coincidence rather than a requirement.)
This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.
If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.
This changes the approach used by the provider installer to remember
between runs which selections it has previously made, using the lock file
format implemented in internal/depsfile.
This means that version constraints in the configuration are considered
only for providers we've not seen before or when -upgrade mode is active.
For reasons that are unclear, these two tests just started failing on
macOS very recently. The failure looked like:
PackageDir: strings.Join({
"/",
+ "private/",
"var/folders/3h/foobar/T/terraform-test-p",
"rovidercache655312854/registry.terraform.io/hashicorp/null/2.0.0",
"/windows_amd64",
},
Speculating that the macOS temporary directory moved into the /private
directory, I added a couple of EvalSymlinks calls and the tests pass
again.
No other unit tests appear to be affected by this at the moment.
Instead of searching the installed provider package directory for a
binary as we install it, we can lazily detect the executable as it is
required. Doing so allows us to separately report an invalid unpacked
package, giving the user more actionable error messages.
* tools/terraform-bundle: refactor to use new provider installer and
provider directory layouts
terraform-bundle now supports a "source" attribute for providers,
uses the new provider installer, and the archive it creates preserves
the new (required) directory hierarchy for providers, under a "plugins"
directory.
This is a breaking change in many ways: source is required for any
non-HashiCorp provider, locally-installed providers must be given a
source (can be arbitrary, see docs) and placed in the expected directory
hierarchy, and the unzipped archive is no longer flat; there is a new
"plugins" directory created with providers in the new directory layout.
This PR also extends the existing test to check the contents of the zip
file.
TODO: Re-enable e2e tests (currently suppressed with a t.Skip)
This commit includes an update to our travis configuration, so the terraform-bundle e2e tests run. It also turns off the e2e tests, which will fail until we have a terraform 0.13.* release under releases.hashicorp.com. We decided it was better to merge this now instead of waiting when we started seeing issues opened from users who built terraform-bundle from 0.13 and found it didn't work with 0.12 - better that they get an immediate error message from the binary directing them to build from the appropriate release.
Providers installed from the registry are accompanied by a list of
checksums (the "SHA256SUMS" file), which is cryptographically signed to
allow package authentication. The process of verifying this has multiple
steps:
- First we must verify that the SHA256 hash of the package archive
matches the expected hash. This could be done for local installations
too, in the future.
- Next we ensure that the expected hash returned as part of the registry
API response matches an entry in the checksum list.
- Finally we verify the cryptographic signature of the checksum list,
using the public keys provided by the registry.
Each of these steps is implemented as a separate PackageAuthentication
type. The local archive installation mechanism uses only the archive
checksum authenticator, and the HTTP installation uses all three in the
order given.
The package authentication system now also returns a result value, which
is used by command/init to display the result of the authentication
process.
There are three tiers of signature, each of which is presented
differently to the user:
- Signatures from the embedded HashiCorp public key indicate that the
provider is officially supported by HashiCorp;
- If the signing key is not from HashiCorp, it may have an associated
trust signature, which indicates that the provider is from one of
HashiCorp's trusted partners;
- Otherwise, if the signature is valid, this is a community provider.
This was incorrectly removing the _source_ entry prior to creating the
symlink, therefore ending up with a dangling symlink and no source file.
This wasn't obvious before because the test case for LinkFromOtherCache
was also incorrectly named and therefore wasn't running. Fixing the name
of that test made this problem apparent.
The TestLinkFromOtherCache test case now ends up seeing the final resolved
directory rather than the symlink target, because of upstream changes
to the internal/getproviders filesystem scanning logic to handle symlinks
properly.
When a system-wide shared plugin cache is configured, we'll want to make
use of entries already in the shared cache when populating a local
(configuration-specific) cache.
This new method LinkFromOtherCache encapsulates the work of placing a link
from one cache to another. If possible it will create a symlink, therefore
retaining a key advantage of configuring a shared plugin cache, but
otherwise we'll do a deep copy of the package directory from one cache
to the other.
Our old provider installer would always skip trying to create symlinks on
Windows because Go standard library support for os.Symlink on Windows
was inconsistent in older versions. However, os.Symlink can now create
symlinks using a new API introduced in a Windows 10 update and cleanly
fail if symlink creation is impossible, so it's safe for us to just
try to create the symlink and react if that produces an error, just as we
used to do on non-Windows systems when possibly creating symlinks on
filesystems that cannot support them.
