Robert Tillery	af77d1d22c	backend/remote: Filter environment variables when loading context (#23358) ... * backend/remote: Filter environment variables when loading context Following up on #23122, the remote system (Terraform Cloud or Enterprise) serves environment and Terraform variables using a single type of object. We only should load Terraform variables into the Terraform context. Fixes https://github.com/hashicorp/terraform/issues/23283.	7 years ago
Martin Atkins	8f27409007	backend/remote: Support HCL variable values in local operations ... For remote operations, the remote system (Terraform Cloud or Enterprise) writes the stored variable values into a .tfvars file before running the remote copy of Terraform CLI. By contrast, for operations that only run locally (like "terraform import"), we fetch the stored variable values from the remote API and add them into the set of available variables directly as part of creating the local execution context. Previously in the local-only case we were assuming that all stored variables are strings, which isn't true: the Terraform Cloud/Enterprise UI allows users to specify that a particular variable is given as an HCL expression, in which case the correct behavior is to parse and evaluate the expression to obtain the final value. This also addresses a related issue whereby previously we were forcing all sensitive values to be represented as a special string "<sensitive>". That leads to type checking errors for any variable specified as having a type other than string, so instead here we use an unknown value as a placeholder so that type checking can pass. Unpopulated sensitive values may cause errors downstream though, so we'll also produce a warning for each of them to let the user know that those variables are not available for local-only operations. It's a warning rather than an error so that operations that don't rely on known values for those variables can potentially complete successfully. This can potentially produce errors in situations that would've been silently ignored before: if a remote variable is marked as being HCL syntax but is not valid HCL then it will now fail parsing at this early stage, whereas previously it would've just passed through as a string and failed only if the operation tried to interpret it as a non-string. However, in situations like these the remote operations like "terraform plan" would already have been failing with an equivalent error message anyway, so it's unlikely that any existing workspace that is being used for routine operations would have such a broken configuration.	7 years ago
Martin Atkins	9f9f22091e	backend/remote: Unlock workspace if Context fails ... Previously any error case in the Context method would cause us to leave the remote workspace locked on exit, requiring manual action to unlock it.	7 years ago
Martin Atkins	b10f058cbb	backend/remote: Only load variables if we're going to use them ... Some commands don't use variables at all or use them in a way that doesn't require them to all be fully valid and consistent. For those, we don't want to fetch variable values from the remote system and try to validate them because that's wasteful and likely to cause unnecessary error messages. Furthermore, the variables endpoint in Terraform Cloud and Enterprise only works for personal access tokens, so it's important that we don't assume we can _always_ use it. If we do, then we'll see problems when commands are run inside Terraform Cloud and Enterprise remote execution contexts, where the variables map always comes back as empty.	7 years ago
