We previously had this just stubbed out because it was a stretch goal for
the v0.13.0 release and it ultimately didn't make it in.
Here we fill out the existing stub -- with a minor change to its interface
so it can access credentials -- with a client implementation that is
compatible with the directory structure produced by the
"terraform providers mirror" subcommand, were the result to be published
on a static file server.
Earlier we introduced a new package hashing mechanism that is compatible
with both packed and unpacked packages, because it's a hash of the
contents of the package rather than of the archive it's delivered in.
However, we were using that only for the local selections file and not
for any remote package authentication yet.
The provider network mirrors protocol includes new-style hashes as a step
towards transitioning over to the new hash format in all cases, so this
new authenticator is here in preparation for verifying the checksums of
packages coming from network mirrors, for mirrors that support them.
For now this leaves us in a kinda confusing situation where we have both
NewPackageHashAuthentication for the new style and
NewArchiveChecksumAuthentication for the old style, which for the moment
is represented only by a doc comment on the latter. Hopefully we can
remove NewArchiveChecksumAuthentication in a future commit, if we can
get the registry updated to use the new hashing format.
When applying a backend config override file, we must not check for the
presence of all required fields, as the override can be a partial
configuration. It is only valid to check for required fields after all
overrides have been merged, which init already does.
From the go release notes:
go1.14.3 (released 2020/05/14) includes fixes to cgo, the compiler, the
runtime, and the go/doc and math/big packages.
go1.14.4 (released 2020/06/01) includes fixes to the go doc command, the
runtime, and the encoding/json and os packages.
go1.14.5 (released 2020/07/14) includes security fixes to the
crypto/x509 and net/http packages.
go1.14.6 (released 2020/07/16) includes fixes to the go command, the
compiler, the linker, vet, and the database/sql, encoding/json,
net/http, reflect, and testing packages.

The installFromHTTPURL function downloads a package to a temporary file,
then delegates to installFromLocalArchive to install it. We were
previously not deleting the temporary file afterwards. This commit fixes
that.
When we need to select a qualified provider address based on an implied
provider name, we have a special case that the name "terraform" maps to
terraform.io/builtin/terraform instead of
registry.terraform.io/hashicorp/terraform as would be the case for other
prefixes.
However, in order for that to work properly we need to use
addrs.ImpliedProviderForUnqualifiedType instead of
addrs.NewDefaultProvider, because the latter just unconditionally always
produces a "default" provider configuration (belonging to the "hashicorp"
namespace on the public registry).
The Resource.Absolute function is there to conveniently construct an
AbsResource from a Resource by providing a module instance. Likewise, this
new InModule method allows conveniently constructing a ConfigResource from
a Resource by providing a module.
When loading a backend config override file, init was doing two things
wrong:
- First, if the file failed to parse, we accidentally didn't return,
which caused a panic due to the parsed body being nil;
- Secondly, we were overzealous with the validation of the file,
allowing only attributes. While most backend configs are attributes
only, the enhanced remote backend body also contains a `workspaces`
block, which we need to support here.
This commit fixes the first bug with an early return and adds test cases
for missing file and intentionally-blank filename (to clear the config).
We also add a schema validation for the backend block, based on the
backend schema itself. This requires constructing an HCL body schema so
that we can call `Content` and check for diagnostic errors.
The result is more useful errors when an invalid backend config override
file is used, while also supporting the enhanced remote backend config
fully.
Does not include tests specific to the remote backend, because the
mocking involved to allow the backend to fully initialize is too
involved to be worth it.
There was a missing outer loop for catching inverse module dependencies
when pruning nodes for destroy. Since the need to "register" the fully
destroyed modules no longer exists, the extra complication of pruning
the modules as a whole from the leaves inward is no longer required.
While it is technically still a valid optimization to reduce iterations,
the extra comparisons required to backtrack for transitive dependencies
don't amount to much, and having a single nested loop is much easier to
maintain.
