This change will await the completion of pre-apply run tasks if they
exist on a run and then report the results.
It also adds an abstraction when interacting with cloud integrations such
as policy checking and cost estimation that simplify and unify output,
although I did not go so far as to refactor those callers to use it yet.
As the cloud e2e tests evolved some common patters became apparent. This
standardizes and consolidates the patterns into a common test runner
that takes the table tests and runs them in parallel. Some tests also
needed to be converted to utilize table tests.
Running tests in parallel can help speed up overall test execution. Go
blocks parent tests while child tests run, so it does not fully fan out
as you might expect. It is noticably faster, though. Running 4 or more
concurrent processes knocks over a minute off the total execution time.
There are a few command line options for "terraform init" which are only
relevant when working with traditional backends, with the Cloud
integration previously just mostly ignoring them, or sometimes misbehaving
slightly due to them creating an unreasonable situation.
Now we'll catch these and return explicit errors, in order to be clear
that these options are not needed nor supported in Cloud mode.
This just gives a little extra information to work with when trying to
understand why a test failed. It doesn't change what any of the tests are
actually trying to test.
This aims to encapsulate the somewhat-weird logic we currently use to
distinguish between the various "terraform init" situations involving
Terraform Cloud mode, in the hope of making codepaths that branch based
on this slightly easier to read.
This isn't yet used, but uses of it will follow in subsequent commits.
This pull request focuses on removing the prompt to rename the default
workspace when it is empty. Functionality already exists to not migrate
an empty workspace. This commit adds some clarifying language in the
comment where we do the evaluation to know whether to ask for a new name
or not. I also added an end to end test, which I should have added to
begin with.
All run variables remain encoded as strings in the API but will now be expressed as an HCL value to be evaluated correctly by the remote terraform. Previously, only strings were supported.
Examples:
string: `"quoted literal"` (strings must be quoted)
map: `{ foo = "bar" }`
list: `["foo", "bar"]`
bool: `true`
null: `null`
number: `0.0001`
This requires the API to anticipate that all run variables will be HCL values
* convert uses of worspaces.operations into workspaces.executionMode
The cloud package currently uses a deprecated API on workspaces to determine a workspace's execution mode.
Deprecated: Operations (boolean)
New hotness: Execution mode (string - "local", "remote", or "agent")
More details: https://www.terraform.io/docs/cloud/api/workspaces.html#request-body
All uses of Operations field coming from the client (within the cloud package) should be converted to the appropriate ExecutionMode equivalent.
Also, we need to update all acknowledgment of operations field on the tests that are testing the behavior of workspaces.

Add the `-parallel N` switch to tell the tests to run in N processes:
```
TFE_TOKEN=$TFE_TOKEN TFE_HOSTNAME=$TFE_HOSTNAME TF_ACC=1 go test -v \
-tags=e2e ./internal/cloud/e2e/... -parallel 4
```
Previously, `terraform init` was throwing an error if you configured the cloud
block with `tags` and there weren't any tagged workspaces yet. Confusing and
alienating, since that that's a fairly normal situation! Basically TFC was
handling an empty list of workspaces worse than other backends, because it
doesn't support an unnamed default workspace.
This commit catches that condition during `Meta.selectBackend()` and asks the
user to pick a name for their first tagged workspace. If they cancel out, we
still error, but if we know what name they want, we can handle it the same way
as a nonexistent workspace specified in `name` -- just pass it to
`Meta.SetWorkspace()`, and let the workspace get implicitly created when
`InitCommand.Run()` eventually calls `StateMgr()`.
When the 'select the exact version if possible' behavior was added, the
version check below it was never updated to take the newly updated
version in to account, resulting in a failed version check even as the
remote workspace updated to the correct version necessary.
E2E tests including cost estimation should indeed be added, but the
default case should be disabled; lots of cycles lost to pointless cost
estimates on null and random resources.
The delete + assign at the end of `Update` and `UpdateByID` are meant to handle
renaming a workspace — (remove old name), (insert new name).
However, `UpdateByID` was doing (remove new name), (insert new name) and leaving
the old name in place. This commit changes it to match `Update` by grabbing the
original name off the workspace object _before_ potentially renaming it.
Alas, there's not a very good way to test the message we're supposed to print to
the console in this situation; we just don't appear to have a mock terminal that
the test can read from. But we can at least test that the function returns
without erroring under the exact conditions where it was erroring before.
Note that the behaviors of mc.Workspaces.Update and UpdateByID were already
starting to drift, so I consolidated their actual attribute update logic into a
helper function before they drifted much further.
Previously, if the remote TFC/TFE instance doesn't happen to have a tool_version
record whose name exactly matches the value of `tfversion.String()`, Terraform
would be completely blocked from using the `terraform workspace new` command
(when configured with the tags strategy) — the API would give a 422 to the
whole create request.
This commit changes the StateMgr() function to do the work in two passes; first
create the workspace (which should work fine regardless), THEN update the
Terraform version and print a warning to the terminal if it fails (which 99% of
the time is a benign failure with little impact on your future CLI usage).
There are actually a few different ways to get to this message.
1. Blank state — no previous terraform applied. Start with a cloud block.
1. Implicit local — start with no backend specified. This actually goes
through the same code execution path as the first scenario.
1. Explicit local — start with a backend local block that has been
applied, then change from the local backend to a cloud block. This
will recognize the state, and is a different path through the code in
the meta backend.
This commit handles the last case. The messaging has also been tweaked.
End to end test included as well.
