Error diags from c.installModules() no longer cause getModules() to exit early.
Whether installModules completed successfully, errored, or was cancelled, we
try to update the manifest as best we can, preferring incomplete information
to none.
Earlier work to make "terraform init" interruptible made the getproviders
package context-aware in order to allow provider installation to be cancelled.
Here we make a similar change for module installation, which is now also
cancellable with SIGINT. This involves plumbing context through initwd and
getmodules. Functions which can make network requests now include a context
parameter whose cancellation cancels those requests.
Since the module installation code is shared, "terraform get" is now
also interruptible during module installation.
* 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.

For Terraform Cloud users using the 'remote' backend, the existing
'pattern' prompt should work just fine - but because their workspaces
are already present in TFC, the 'migration' here is really just
realigning their local workspaces with Terraform Cloud. Instead of
forcing users to do the mental gymnastics of what it means to migrate
from 'prefix' - and because their remote workspaces probably already exist and
already conform to Terraform Cloud's naming concerns - streamline the
process for them and calculate the necessary pattern to migrate as-is,
without any user intervention necessary.
After migrating to TFC with renamed workspaces, automatically select
what was the previous current workspace on behalf of the user. We don't
need to make the user reselect.
Note these change do break the internal/cloud/e2e tests; they are in a
sad state that needs adjusting anyway, so I'm not updating them for
these changes at this time.
The Meta.backend_C_r_S_unchanged() method was sadly a bit of a mess.
It seems to have originally been used as a method to be called
when the backend is not changing, with an extra assumption that if the
configured backend's hash doesn't match the one in state, surely the
hash should just be updated as an option might have been moved to
command line flags.
However, this function was used throughout this file as 'the method to
load the initialized (but not necessarily configured) backend',
regardless of whether or not it is the same (unchanged). This is in
addition to Meta.backendFromState(), which is used to load the same
thing except in the main codepath of 'init -backend=false'.
These changes separate the concerns of backend_C_r_S_unchanged() by
1) Fetching the saved backend (savedBackend())
2) Updating the hash value in the backend cache when appropriate (either
by leaving it to the caller to do themselves or by calling
updateSavedupdateSavedBackendHash())
This allows migration codepaths to *not* update the hash value until
after a migration has successfully taken place.
Allow `GetResource` to return correct types values during validation,
rather than relying on `cty.DynamicVal` as a placeholder. This allows
other dependent expressions to be more correctly evaluated.
* command/format: fix list nested attr diff rendering
Previously, diffs only rendered correctly if all changed elements
appeared before all unchanged elements. Once an unchanged element was
found, all remaining elements were skipped. This usually led to the
output being an empty list with a weird amount of space between the
brackets.
* command/format: improve list nested attr rendering
This makes several changes that make diffs for lists clearer and more
consistent:
* Separate items with brackets instead of only new lines. This better
matches the input syntax and avoids confusion from the first and
last brackets implying there is a single item.
* Render an action symbol for each element of the list
* Use the correct action symbol for new and deleted items
* Fix the alignment of opening and closing brackets
I also refactored the structure so it is similar to the set and map
cases to minimize duplication of the new prints.
* Fix re-use of blockBodyDiffResult struct
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()`.
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.
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.
