This fixes several bugs:
- `substr("abc", 0, 0)` would previously return `"abc"`, despite the
length argument being `0`. This has been changed to return an empty
string when length is zero.
- `ceil(1/0)` and `floor(1/0)` would previously return a large integer
value, rather than infinity. This has been fixed.
This library implements the user-specific directory layout specifications
for various platforms (XDG on Unix, "Known Folders" on Windows, etc).
We'll use this in a subsequent commit to add additional system-specific
search directories for provider plugins, and perhaps later on also
CLI configuration directories.
* add TencentCloud COS backend for remote state
* add vendor of dependence
* fixed error not handle and remove default value for prefix argument
* get appid from TF_COS_APPID environment variables
These are intended to make it easier to work with arbitrary data
structures whose shape might not be known statically, such as the result
of jsondecode(...) or yamldecode(...) of data from a separate system.
For example, in an object value which has attributes that may or may not
be set we can concisely provide a fallback value to use when the attribute
isn't set:
try(local.example.foo, "fallback-foo")
Using a "try to evaluate" model rather than explicit testing fits better
with the usual programming model of the Terraform language where values
are normally automatically converted to the necessary type where possible:
the given expression is subject to all of the same normal type conversions,
which avoids inadvertently creating a more restrictive evaluation model
as might happen if this were handled using checks like a hypothetical
isobject(...) function, etc.
This brings in the new HCL extension functions "try", "can", and
"convert", along with the underlying HCL and cty infrastructure that allow
them to work.
* deps: bump terraform-config-inspect library
* configs: parse `version` in new required_providers block
With the latest version of `terraform-config-inspect`, the
required_providers attribute can now be a string or an object with
attributes "source" and "version". This change allows parsing the
version constraint from the new object while ignoring any given source attribute.
This also includes an upgrade to cty v1.1.1 because HCL calls for it.
The changes in these two libraries are mainly to codepaths that don't
directly affect Terraform, but including this upgrade will cause some
small improvements to Terraform's error messages for type conversion
problems.
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.
This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.
For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.
This new version includes Solaris support, the lack of which previously
caused us to disable readline-using features ("terraform console") on
Solaris builds.
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
}
}
```
