Add the expansion transformer to the eval graph,
which is used in rare scenarios which includes running
terraform console. Prevents panic when running terraform
console in contexts with module expansion
We now permit at most one `required_providers` block per module (except
for overrides). This prevents users (and Terraform) from struggling to
understand how to merge multiple `required_providers` configurations,
with `version` and `source` attributes split across multiple blocks.
Because only one `required_providers` block is permitted, there is no
need to concatenate version constraints and resolve them. This allows us
to simplify the structs used to represent provider requirements,
aligning more closely with other structs in this package.
This commit also fixes a semantic use-before-initialize bug, where
resources defined before a `required_providers` block would be unable to
use its source attribute. We achieve this by processing the module's
`required_providers` configuration (and overrides) before resources.
Overrides for `required_providers` work as before, replacing the entire
block per provider.

NOTES:
* backend/s3: Region validation now automatically supports the new `af-south-1` (Africa (Cape Town)) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the [AWS Documentation](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable). When the region is not enabled, the Terraform S3 Backend will return errors during credential validation (e.g. `error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid`).

Since objects and tuples have fixed numbers of elements, we can't return
an unknown version of those during validation. While we could return a
DyanmicVal (which was used previously), that prevents the validation of
outputs and attributes in config references.
Instead, we can return a synthetic type made from a List or Map based
on the configuration, which will allow us to more precisely validate
indexes, attributes, and outputs.
Because tuple types have a fixed number of elements, and we may not know
the number of expanded instances, we can't use an unknown tuple type to
validate index expressions.
Since evaluation is driven only by the configuration (i.e. you can't
interpolate what's not in the config), the resource evaluation should
also follow configuration rather than state. Determining the each mode
solely from the config, and applying that to the state and changes
removes the need for EachMode in the resource state. This bypasses the
awkward dance around getting the correct EachMode set in and retrieved
from state during plan when it changes in the config.
* internal/getproviders: apply case normalizations in ParseMultiSourceMatchingPatterns
This is a very minor refactor which takes advantage of addrs.ParseProviderPart case normalization to normalize non-wildcard sources.
These were being used in an earlier iteration of the provider installation
configuration but it was all collapsed down into a single
ProviderInstallationMethod type later, making these redundant.
This is an initial draft of documentation for this new feature of the
CLI configuration. This is mainly intended as a placeholder for now,
because there are other documentation updates pending for the new provider
namespacing and installation scheme and we'll likely want to revise these
docs to better complement the broader documentation once it's written.
This exercises the ability to customize the installation methods used by
the provider plugin installer, in this case forcing the use of a custom
local directory with a result essentially the same as what happens when
you pass -plugin-dir to "terraform init".
The CLI config can be written in both native HCL and HCL JSON syntaxes, so
the provider_installation block must be expressible using JSON too. Our
previous checks to approximate HCL 2-level strictness were too strict for
HCL JSON where things are more ambiguous even in HCL 2, so this includes
some additional relaxations if we detect that we're decoding an AST
produced from a JSON file.
This is still subject to the quirky ways HCL 1 handles JSON though, so
the JSON value must be structured in a way that doesn't trigger HCL's
heuristics that try to guess what is a block and what is an attribute.
(This is the issue that HCL 2 fixes by always decoding using a schema;
there's more context on this in:
https://log.martinatkins.me/2019/04/25/hcl-json/ )
Unfortunately in the user model the noun "source" is already used for the
argument in the required_providers block to specify which provider to use,
so it's confusing to use the same noun to also refer to the method used to
obtain that provider.
In the hope of mitigating that confusion, here we use the noun "method",
as in "installation method", to talk about the decision between getting
a provider directly from its origin registry or getting it from some
mirror. This is distinct from the provider's "source", which is the
location where a provider _originates_ (prior to mirroring).
This noun is also not super awesome, but better than overloading an
existing term in the same feature.
In the first pass of implementing this it was strict about what arguments
are allowed inside source blocks, but that was counter to our usual design
principles for CLI config where we tend to ignore unrecognized things to
allow for some limited kinds of future expansion without breaking
compatibility with older versions of Terraform that will be sharing the
same CLI configuration files with newer versions.
However, I'd removed the tracking of that prior to the initial commit. I
missed some leftover parts when doing that removal, so this cleans up the
rest of it.
An earlier commit added a redundant stub for a new network mirror source
that was already previously stubbed as HTTPMirrorSource.
This commit removes the unnecessary extra stub and changes the CLI config
handling to use it instead. Along the way this also switches to using a
full base URL rather than just a hostname for the mirror, because using
the usual "Terraform-native service discovery" protocol here doesn't isn't
as useful as in the places we normally use it (the mirror mechanism is
already serving as an indirection over the registry protocol) and using
a direct base URL will make it easier to deploy an HTTP mirror under
a path prefix on an existing static file server.
When we originally introduced this environment variable it was intended to
solve for the use-case where a particular invocation of Terraform needs
a different CLI configuration than usual, such as if Terraform is being
run as part of an automated test suite or other sort of automated
situation with different needs than normal use.
However, we accidentally had it only override the original singleton CLI
config file, while leaving the CLI configuration directory still enabled.
Now we'll take the CLI configuration out of the equation too, so that only
the single specified configuration file and any other environment-sourced
settings will be included.
* internal/providercache: verify that the provider protocol version is
compatible
The public registry includes a list of supported provider protocol
versions for each provider version. This change adds verification of
support and adds a specific error message pointing users to the closest
matching version.
If the CLI configuration contains a provider_installation block then we'll
use the source configuration it describes instead of the implied one we'd
build otherwise.
This is a placeholder for later implementation of a mirror source that
talks to a particular remote HTTP server and expects it to implement the
provider mirror protocol.
This new CLI config block type allows explicitly specifying where
Terraform should look to find provider plugins for installation. This is
not used anywhere as of this commit, but in a future commit we'll change
package main to treat the presence of a block of this type as a request
to disable the default set of provider sources and use these explicitly-
specified ones instead.
* 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.
A side effect of the various changes to the provider installer included losing the initialization required error message which would occur if a user removed or modified the .terraform directory.
Previously, plugin factories were created after the configuration was loaded, in terraform.NewContext. Terraform would compare the required providers (from config and state) to the available providers and return the aforementioned error if a provider was missing.
Provider factories are now loaded at the beginning of any terraform command, before terraform even loads the configuration, and therefore before terraform has a list of required providers.
This commit replaces the current error when a providers' schema cannot be found in the provider factories with the init error, and adds a command test (to plan tests, for no real reason other than that's what I thought of first).
