The dependencies here are dated and are causing conflicts with the
ACME provider, namely the version of the top-level autorest package.
This explicitly updates the Azure SDK and autorest packages, with the
separately versioned sub-packages being added automatically.
Notable changes (from Terraform AWS Provider CHANGELOG):
```
NOTES:
* backend/s3: Region validation now automatically supports the new `me-south-1` Middle East (Bahrain) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the [previous new region announcement blog post](https://aws.amazon.com/blogs/aws/now-open-aws-asia-pacific-hong-kong-region/). 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`).
* backend/s3: After this update, the AWS Go SDK will prefer credentials found via the `AWS_PROFILE` environment variable when both the `AWS_PROFILE` environment variable and the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` environment variables are statically defined. Previously the SDK would ignore the `AWS_PROFILE` environment variable, if static environment credentials were also specified. This is listed as a bug fix in the AWS Go SDK release notes.
ENHANCEMENTS:
* backend/s3: Add support for assuming role via web identity token via the `AWS_WEB_IDENTITY_TOKEN_FILE` and `AWS_ROLE_ARN` environment variables
* backend/s3: Support automatic region validation for `me-south-1`
BUG FIXES:
* backend/s3: Load credentials via the `AWS_PROFILE` environment variable (if available) when `AWS_PROFILE` is defined along with `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`
```
Updated via:
```
go get github.com/aws/aws-sdk-go@v1.21.7
go mod tidy
go mod vendor
```
Verification with this update:
```hcl
terraform {
backend "s3" {
bucket = "me-south-1-testing"
key = "test"
region = "me-south-1"
}
}
output "test" {
value = timestamp()
}
```
Outputs:
```
$ terraform apply
Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
Outputs:
test = 2019-07-30T12:49:19Z
```
If the new region is not properly enabled for the account, errors like the below will be received:
```
$ terraform init
Initializing the backend...
Error: error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid.
```
To use this region before this update:
```hcl
terraform {
# ... potentially other configuration ...
backend "s3" {
# ... other configuration ...
region = "me-south-1"
skip_region_validation = true
}
}
```
This includes a fix to make sure that an expression with a static string
index, like foo["bar"], will be parsed as a traversal rather than as a
dynamic index expression.
This module contains a YAML parser and encoder tailored to cty, though we
are mostly interested in it for its YAMLEncode and YAMLDecode cty
functions, which we can make available in Terraform.
This includes a small fix to ensure the parser doesn't produce an invalid
body for block parsing syntax errors, and instead produces an incomplete
result that calling applications like Terraform can still analyze.
The problem here was affecting our version-constraint-sniffing code, which
intentionally tried to find a core version constraint even if there's a
syntax error so that it can report that a new version of Terraform is a
likely cause of the syntax error. It was working in most cases, unless
it was the "terraform" block itself that contained the error, because then
we'd try to analyze a broken hcl.Block with a nil body.
This includes a new test for "terraform init" that exercises this
recovery codepath.
This corrects a bug in the HCL 2 scanner where a $ or % symbol would cause
incorrect tokenization if appearing immediately before a " .
This also includes some updates to Go extension libraries that the HCL
update brings in. Some of these changes update to support Unicode 11, but
only when compiling with Go 1.13, so we won't see the effect of these
changes until we start building Terraform with Go 1.13.
This contains an adjustment to how the dynamic blocks extension expands
a dynamic block whose for_each expression is unknown: it now produces an
block whose leaf attributes are all unknown, which is what Terraform had
previously been expecting but it wasn't actually true in practice.
cty now guarantees that sets of primitive values will iterate in a
reasonable order. Previously it was the caller's responsibility to deal
with that, but we invariably neglected to do so, causing inconsistent
ordering. Since cty prioritizes consistent behavior over performance, it
now imposes its own sort on set elements as part of iterating over them so
that calling applications don't have to worry so much about it.
This change also causes cty to consistently push unknown and null values
in sets to the end of iteration, where before that was undefined. This
means that our diff output will now consistently list additions before
removals when showing sets, rather than the ordering being undefined as
before.
The ordering of known, non-null, non-primitive values is still not
contractually fixed but remains consistent for a particular version of
cty.
This gives us an extra hook in the dynblock variables analysis that should
allow us to also make it subject also to the lang/blocktoattr fixup, to
ensure we'll find all the references in spite of these various
pre-processing wrappers.
