This also fixes a few things with resource for_each:
It makes validation more like validation for count.
It makes sure the index is stored in the state properly.
In some cases (see #22020 for a specific example), the parsed hilNode
can be nil. This causes a series of panics. Instead, return an error and
move on.
* command/init: omit a warning if -backend-config is used with no backend
block
Terraform would silently accept - and swallow - `-backend-config` on the
CLI when there was no `backend` block. Since it is mostly expected to
override existing backend configuration, terraform
should omit a warning if there is no backend configuration to
override.
If the user intended to override the default (local) backend
configuration, they can first add a `backend` block to the `terraform` block to silence the warning (or just ignore it):
```hcl
terraform {
backend "local" {}
}
```
Mistakenly using dynamic on an attribute will lead to a panic when
attempting to resolve variable references with a partial body, because
the dynamic blocks have yet to be expanded and validated. Check that the
block element type is actually an object before generating a schema.
Previously, terraform was returning a potentially-misleading error
message in response to anything other than a 404 from the
b.client.Workspaces.Read operation. This PR simplifies Terraform's error
message with the intent of encouraging those who encounter it to focus
on the error message returned from the tfe client.
The added test is odd, and a bit hacky, and possibly overkill.
1) Mention the host and port in the "Connecting..." message.
2) Mention the username in the post-connection handshaking message.
3) If handshaking fails, mention the user, host, and port in the error
message that will eventually be returned to the user.
Some of our errors returned here were lacking context about what part of
the file was problematic, which led to some useless error reporting for
some real-world situations that this upgrade process doesn't seem to be
catching.
Here we add additional context to those error cases, as a step towards
tracking down exactly which upgrade cases are missing here so that we can
potentially fix them in a subsequent release.
When a TFC workspace is configured without a VCS root, and with a
working directory, and a user is running `terraform init` from that same
directory, TFC uploads the entire configuration directory, not only the
user's cwd. This is not obvious to the user, so we are adding a descriptive
message explaining what is being uploaded, and why.
