The remote backend tests spent most of their execution time sleeping in
various polling and backoff waits. This is unnecessary when testing
against a mock server, so reduce all of these delays when under test to
much lower values.
Only one remaining test has an artificial delay: verifying the discovery
of services against an unknown hostname. This times out at DNS
resolution, which is more difficult to fix than seems worth it at this
time.
* unlock the state if Context() has an error, exactly as backend/remote does today
* terraform console and terraform import will exit before unlocking state in case of error in Context()
* responsibility for unlocking state in the local backend is pushed down the stack, out of backend.go and into each individual state operation
* add tests confirming that state is not locked after apply and plan
* backend/local: add checks that the state is unlocked after operations
This adds tests to plan, apply and refresh which validate that the state
is unlocked after all operations, regardless of exit status. I've also
added specific tests that force Context() to fail during each operation
to verify that locking behavior specifically.
The remote server might choose to skip running cost estimation for a
targeted plan, in which case we'll show a note about it in the UI and then
move on, rather than returning an "invalid status" error.
This new status isn't yet available in the go-tfe library as a constant,
so for now we have the string directly in our switch statement. This is
a pragmatic way to expedite getting the "critical path" of this feature
in place without blocking on changes to ancillary codebases. A subsequent
commit should switch this over to tfe.CostEstimateSkippedDueToTargeting
once that's available in a go-tfe release.
Previously we did not allow -target to be used with the remote backend
because there was no way to send the targets to Terraform Cloud/Enterprise
via the API.
There is now an attribute in the request for creating a plan that allows
us to send target addresses, so we'll remove that restriction and copy
the given target addresses into the API request.
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.
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.
* backend/enhanced: start with absolute config path
We recently started normalizing the config path before all "command"
operations, which was necessary for consistency but had unexpected
consequences for remote backend operations, specifically when a vcs root
with a working directory are configured.
This PR de-normalizes the path back to an absolute path.
* Check the error and add a test
It turned out all required logic was already present, so I just needed to add a test for this specific use case.
Use the entitlements to a) determine if the organization exists, and b) as a means to select which backend to use (the local backend with remote state, or the remote backend).
In order to support free organizations, we need a way to load the `remote` backend and then, depending on the used offering/plan, enable or disable remote operations.
In other words, we should be able to dynamically fall back to the `local` backend if needed, after first configuring the `remote` backend.
To make this works we need to change the way this was done previously when the env var `TF_FORCE_LOCAL_BACKEND` was set. The clear difference of course being that the env var would be available on startup, while the used offering/plan is only known after being able to connect to TFE.
This work was done against APIs that were already changed in the branch
before work began, and so it doesn't apply to the v0.12 development work.
To allow v0.12 to merge down to master, we'll revert this work out for now
and then re-introduce equivalent functionality in later commits that works
against the new APIs.
In some cases this is needed to keep the UX clean and to make sure any remote exit codes are passed through to the local process.
The most obvious example for this is when using the "remote" backend. This backend runs Terraform remotely and stream the output back to the local terminal.
When an error occurs during the remote execution, all the needed error information will already be in the streamed output. So if we then return an error ourselves, users will get the same errors twice.
By allowing the backend to specify the correct exit code, the UX remains the same while preserving the correct exit codes.
In TFE you can configure a workspace to use a custom working directory. When determining which directory that needs to be uploaded to TFE, this working directory should be taken into account to make sure we are uploading the correct root directory for the workspace.
