Fix the logic to add proxy provider nodes for implicitly passed in
providers. The missing continue allowed multiple nodes satisfying the
same provider address to be added to the graph. When attaching the
providers to resources, the fist one encountered would be used, which
could change each time the graph was built.
* providers.Interface: huge renamification
This commit renames a handful of functions in the providers.Interface to
match changes made in protocol v6. The following commit implements this
change across the rest of the codebase; I put this in a separate commit
for ease of reviewing and will squash these together when merging.
One noteworthy detail: protocol v6 removes the config from the
ValidateProviderConfigResponse, since it's never been used. I chose to
leave that in place in the interface until we deprecate support for
protocol v5 entirely.
Note that none of these changes impact current providers using protocol
v5; the protocol is unchanged. Only the translation layer between the
proto and terraform have changed.
* command/format: check for sensitive NestedTypes
Eventually, the diff formatter will need to be updated to properly
handle NestedTypes, but for now we can let the existing function deal
with them as regular cty.Object-type attributes.
To avoid printing sensitive nested attributes, we will treat any
attribute with at least one sensitive nested attribute as an entirely
sensitive attribute.
* bugfix for Object ImpliedType()
ImpliedType() was returning too early when the given object had optional
attributes, therefore skipping the incredibly important step of
accounting for the nesting mode when returning said type.
Add a test for a diagnostic with no steps to make sure it still gets
associated with the resource in the config. Follow up to #27710 using
@alisdair's suggested testing.
The PreApply hook was always being called with a nil generation
argument, instead of the deposed key of the resource (if present). This
commit passes the deposed key from the change to the PreApply hook, and
adds a context test to cover this.
Due to calling the Colorize function with the full string instead of the
format string, plan/apply logs which include resource instance keys or
IDs which happen to match color formatting would be rendered
incorrectly.
This commit fixes this by only colorizing the known-safe format string.
We also add full test coverage for the UI hook, although only one of the
hooks is tested for this color bugfix due to verbosity of the test.
We also add the bold coloring to the provisioner output prefix, which
seems to have been an oversight.
The call to TestConformance needs to be reversed, since we want to
verify that the actual value returned conforms to the planned type.
While the inverse (checking that the planned value conforms to the
applied type) works for everything terraform has been exposed to up
until now, this fails when the planned type has dynamic attributes which
are allowed to become concrete types.
Now that the view code is separated, we can increase test coverage in
unit tests. This commit moves some tests from the command package which
were testing only view code, and adds more new test cases.
The warning diag added when refreshing an empty state file was never
rendered, and instead a custom (and incorrect) warning was output to the
UI. This commit fixes the dropped diag and removes the custom warning.
The clistate package includes a Locker interface which provides a simple
way for the local backend to lock and unlock state, while providing
feedback to the user if there is a delay while waiting for the lock.
Prior to this commit, the backend was responsible for initializing the
Locker, passing through direct access to the cli.Ui instance.
This structure prevented commands from implementing different
implementations of the state locker UI. In this commit, we:
- Move the responsibility of creating the appropriate Locker to the
source of the Operation;
- Add the ability to set the context for a Locker via a WithContext
method;
- Replace the Locker's cli.Ui and Colorize members with a StateLocker
view;
- Implement views.StateLocker for human-readable UI;
- Update the Locker interface to return detailed diagnostics instead of
errors, reducing its direct interactions with UI;
- Add a Timeout() method on Locker to allow the remote backend to
continue to misuse the -lock-timeout flag to cancel pending runs.
When an Operation is created, the StateLocker field must now be
populated with an implementation of Locker. For situations where locking
is disabled, this can be a no-op locker.
This change has no significant effect on the operation of Terraform,
with the exception of slightly different formatting of errors when state
locking or unlocking fails.
Move the code which renders Terraform hook callbacks as UI into the
views package, backed by a views.View instead of a cli.Ui. Update test
setup accordingly.
To allow commands to control this hook, we add a hooks member on the
backend Operation struct. This supersedes the hooks in the Terraform
context, which is not directly controlled by the command logic.
This commit should not change how Terraform works, and is refactoring in
preparation for more changes which move UI code out of the backend.
The enhanced backends (local and remote) need to be able to render
diagnostics during operations. Prior to this commit, this functionality
was supported with a per-backend `ShowDiagnostics` function pointer.
In order to allow users of these backends to control how diagnostics are
rendered, this commit moves that function pointer to the `Operation`
type. This means that a diagnostic renderer is configured for each
operation, rather than once per backend initialization.
Some secondary consequences of this change:
- The `ReportResult` method on the backend is now moved to the
`Operation` type, as it needs to access the `ShowDiagnostics` callback
(and nothing else from the backend);
- Tests which assumed that diagnostics would be written to the backend's
`cli.Ui` instance are migrated to using a new record/playback diags
helper function;
- Apply, plan, and refresh commands now pass a pointer to the `Meta`
struct's `showDiagnostics` method.
This commit should not change how Terraform works, and is refactoring in
preparation for more changes which move UI code out of the backend.
It's pretty common to want to apply the various fmt.Fprint... functions
to our two output streams, and so to make that much less noisy at the
callsite here we have a small number of very thin wrappers around the
underlying fmt package functionality.
Although we're aiming to not have too much abstraction in this "terminal"
package, this seems justified in that it is only a very thin wrapper
around functionality that most Go programmers are already familiar with,
and so the risk of this causing any surprises is low and the improvement
to readability of callers seems worth it.
