Now that the most common cause of unknowns (invalid resource indexes) is
caught earlier, we can validate that the final apply config is wholly
known before attempting to apply it. This ensures that we're applying
the configuration we intend, and not silently dropping values.
Continue only evaluating resource at a whole and push the indexing of
the resource down into the expression evaluation.
The exception here is that `self` must be an instance which must be
extracted from the resource. We now also add the entire resource to the
context, which was previously only partially populated with the self
referenced instance.
Always return the entire resource object from
evaluationStateData.GetResource, rather than parsing the references for
individual instances. This allows for later evaluation of resource
indexes so we can return errors when they don't exist, and prevent
errors when short-circuiting around invalid indexes in conditionals.
In order to allow lazy evaluation of resource indexes, we can't index
resources immediately via GetResourceInstance. Change the evaluation to
always return whole Resources via GetResource, and index individual
instances during expression evaluation.
This will allow us to always check for invalid index errors rather than
returning an unknown value and ignoring it during apply.
The documentation for the -target option warns that it's intended for
exceptional circumstances only and not for routine use, but that's not a
very prominent location for that warning and so some users miss it.
Here we make the warning more prominent by including it directly in the
Terraform output when -target is in use. We first warn during planning
that the plan might be incomplete, and then warn again after apply
concludes and direct the user to run "terraform plan" to make sure that
there are no further changes outstanding. The latter message is intended
to reinforce that -target should only be a one-off operation and that you
should always run without it soon after to ensure that the workspace is
left in a consistent, converged state.
main.ConfigDir is just a wrapper around cliconfig.ConfigDir to allow us to
gradually clean up the old calls here, but since this is new code we might
as well do it right from the start.
We're not ready to ship this in a release yet because there's still some
remaining work to do on the Terraform Cloud side, but we want to get the
implementation work behind this into the master branch so it's easier to
maintain it in the mean time, rather than letting this long-lived branch
live even longer.
We'll continue to iterate on UX polish and other details in subsequent
commits, and eventually enable this.
This was a vestige from earlier prototyping when we were considering
supporting adding credentials to existing .tfrc native syntax files.
However, that proved impractical because the CLI config format is still
HCL 1.0 and that can't reliably perform programmatic surgical updates,
so we'll remove this option for now. We might add it back in later if it
becomes more practical to support it.
These run against a stub OAuth server implementation, verifying that we
are able to run an end-to-end login transaction for both the authorization
code and the password grant types.
This includes adding support for authorization code grants to our stub
OAuth server implementation; it previously supported only the password
grant type.
For unit testing in particular we can't launch a real browser for testing,
so this indirection is primarily to allow us to substitute a mock when
testing a command that can launch a browser.
This includes a simple mock implementation that expects to interact with
a running web server directly.
