Based on feedback during earlier alpha releases, we've decided to move
forward with the current design for the first phase of config-driven
refactoring.
Therefore here we've marked the experiment as concluded with no changes
to the most recent incarnation of the functionality. The other changes
here are all just updating test fixtures to no longer declare that they
are using experimental features.
When using the Terraform Cloud integration - like the 'remote'
backend - resource count output should be suppressed if those counts are
being rendered remotely. This generalizes this to the shared
BackendWithRemoteTerraformVersion interface.
Terraform is no longer going to silently capture all logs for a possible
crash report, and therefor won't create a crash.log file when a panic is
encountered.
The prompt to create a log file with TF_LOG from the Debug Output
section should suffice to get users to submit the logs when possible. In
the case of a crash specifically, the crash output also requests that
the stack trace be added to the issue for users who may not be aware of
what is necessary.
The current behavior of module input variables is to allow users to
override a default by assigning `null`, which works contrary to the
behavior of resource attributes, and prevents explicitly accepting a
default when the input must be defined in the configuration.
Add a new variable attribute called `nullable` will allow explicitly
defining when a variable can be set to null or not. The current default
behavior is that of `nullable=true`.
Setting `nullable=false` in a variable block indicates that the variable
value can never be null. This either requires a non-null input value, or
a non-null default value. In the case of the latter, we also opt-in to
the new behavior of a `null` input value taking the default rather than
overriding it.
In a future language edition where we make `nullable=false` the default,
setting `nullable=true` will allow the legacy behavior of `null`
overriding a default value. The only future configuration in which this
would be required even if the legacy behavior were not desired is when
setting an optional+nullable value. In that case `default=null` would
also be needed and we could therefor imply `nullable=true` without
requiring it in the configuration.
A more native integration for Terraform Cloud and its CLI-driven run workflow.
Instead of a backend, users declare a special block in the top-level terraform settings
block to configure Terraform Cloud, then run terraform init.
Full documentation will follow in later commits.
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.
