The providers schema command is using the Config.ProviderTypes method,
which had not been kept up to date with the changes to provider
requirements detection made in Config.ProviderRequirements. This
resulted in any currently-unused providers being omitted from the
output.
This commit changes the ProviderTypes method to use the same underlying
logic as ProviderRequirements, which ensures that `required_providers`
blocks are taken into account.
Includes an integration test case to verify that this fixes the provider
schemas command bug.
The prior state recorded in the plans did not match the actual prior
state. Make the plans and state match depending on whether there was
existing state or not.
Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.

Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.
Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.
We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.
Mark sensitivity on a value. However, when the value is encoded to send to the
provider to produce a changeset we must remove the marks, so unmark the value
and remark it with the saved path afterwards
When rendering a diff between current state and projected state, we only
show resources and outputs which have changes. However, we show a full
structural diff for these values, which includes all attributes and
blocks for a changed resource or output. The result can be a very long
diff, which makes it difficult to verify what the changed fields are.
This commit adds an experimental concise diff renderer, which suppresses
most unchanged fields, only displaying the most relevant changes and
some identifying context. This means:
- Always show all identifying attributes, initially defined as `id`,
`name`, and `tags`, even if unchanged;
- Only show changed, added, or removed primitive values: `string`,
`number`, or `bool`;
- Only show added or removed elements in unordered collections and
structural types: `map`, `set`, and `object`;
- Show added or removed elements with any surrounding unchanged elements
for sequence types: `list` and `tuple`;
- Only show added or removed nested blocks, or blocks with changed
attributes.
If any attributes, collection elements, or blocks are hidden, a count
is kept and displayed at the end of the parent scope. This ensures that
it is clear that the diff is only displaying a subset of the resource.
The experiment is currently enabled by default, but can be disabled by
setting the TF_X_CONCISE_DIFF environment variable to 0.
This new option is intended to address the previous inconsistencies where
some older subcommands supported partially changing the target directory
(where Terraform would use the new directory inconsistently) where newer
commands did not support that override at all.
Instead, now Terraform will accept a -chdir command at the start of the
command line (before the subcommand) and will interpret it as a request
to direct all actions that would normally be taken in the current working
directory into the target directory instead. This is similar to options
offered by some other similar tools, such as the -C option in "make".
The new option is only accepted at the start of the command line (before
the subcommand) as a way to reflect that it is a global command (not
specific to a particular subcommand) and that it takes effect _before_
executing the subcommand. This also means it'll be forced to appear before
any other command-specific arguments that take file paths, which hopefully
communicates that those other arguments are interpreted relative to the
overridden path.
As a measure of pragmatism for existing uses, the path.cwd object in
the Terraform language will continue to return the _original_ working
directory (ignoring -chdir), in case that is important in some exceptional
workflows. The path.root object gives the root module directory, which
will always match the overriden working directory unless the user
simultaneously uses one of the legacy directory override arguments, which
is not a pattern we intend to support in the long run.
As a first step down the deprecation path, this commit adjusts the
documentation to de-emphasize the inconsistent old command line arguments,
including specific guidance on what to use instead for the main three
workflow commands, but all of those options remain supported in the same
way as they were before. In a later commit we'll make those arguments
produce a visible deprecation warning in Terraform's output, and then
in an even later commit we'll remove them entirely so that -chdir is the
single supported way to run Terraform from a directory other than the
one containing the root module configuration.
Most of the functionality for rendering output changes is covered by the
tests for ResourceChanges, as they both share the same diff renderer.
This commit adds a few tests to cover some of the output specific code.
* Return an error on unlock failure
When the lock can't be released return the err even if there is no previous error with the current action. This allows faster failure in CI/CD systems. Without this failure to remove the lock would result in the failure happening on a subsequent plan or apply which slows down the feedback loop in automated systems.

When init attempts to install a legacy provider required by state and
fails, but another provider with the same type is successfully
installed, this almost definitely means that the user is migrating an
in-house provider. The solution here is to use the `terraform state
replace-provider` subcommand.
This commit makes that next step clearer, by detecting this specific
case, and displaying a list of commands to fix the existing state
provider references.
Diagnostic detail lines sometimes contain lines which include commands
suggested for the user to execute. By convention, these start with
leading whitespace to indicate that they are not prose.
This commit changes the diagnostic formatter to wrap each line of the
detail separately, and skips word wrapping for lines prefixed with
space. This prevents ugly and confusing wrapping of long command lines.
This pull reverts a recent change to backend/local which created two context, one with and one without state. Instead I have removed the state entirely from the validate graph (by explicitly passing a states.NewState() to the validate graph builder).
This changed caused a test failure, which (ty so much for the help) @jbardin discovered was inaccurate all along: the test's call to `Validate()` was actually what was removing the output from state. The new expected test output matches terraform's actual behavior on the command line: if you use -target to destroy a resource, an output that references only that resource is *not* removed from state even though that test would lead you to believe it did.
This includes two tests to cover the expected behavior:
TestPlan_varsUnset has been updated so it will panic if it gets more than one request to input a variable
TestPlan_providerArgumentUnset covers #26035Fixes#26035, #26027
If a provider changes namespace in the registry, we can detect this when
running the 0.13upgrade command. As long as there is a version matching
the user's constraints, we now use the provider's new source address.
Otherwise, warn the user that the provider has moved and a version
upgrade is necessary to move to it.
When the output subcommand is called with no arguments, and there are no
outputs to show, we previously rendered an error message but returned a
non-error status code. This is confusing.
This commit changes the text UI to use a warning diagnostic, which makes
it clearer that this is a non-error situation. We do not change the exit
code or the text of the warning, so hopefully this is not considered a
breaking change.
When applying a backend config override file, we must not check for the
presence of all required fields, as the override can be a partial
configuration. It is only valid to check for required fields after all
overrides have been merged, which init already does.
When loading a backend config override file, init was doing two things
wrong:
- First, if the file failed to parse, we accidentally didn't return,
which caused a panic due to the parsed body being nil;
- Secondly, we were overzealous with the validation of the file,
allowing only attributes. While most backend configs are attributes
only, the enhanced remote backend body also contains a `workspaces`
block, which we need to support here.
This commit fixes the first bug with an early return and adds test cases
for missing file and intentionally-blank filename (to clear the config).
We also add a schema validation for the backend block, based on the
backend schema itself. This requires constructing an HCL body schema so
that we can call `Content` and check for diagnostic errors.
The result is more useful errors when an invalid backend config override
file is used, while also supporting the enhanced remote backend config
fully.
Does not include tests specific to the remote backend, because the
mocking involved to allow the backend to fully initialize is too
involved to be worth it.
If a module has multiple terraform.required_version constraints, any
failures would point at the last constraint in the error diagnostics. If
an earlier constraint was the actual problem, this leads to confusing
errors like this:
Error: Unsupported Terraform Core version
on main.tf line 6, in terraform:
6: required_version = ">= 0.13.0"
This configuration does not support Terraform version 0.13.0.
The error was due to storing the declaration range of the constraint as
a pointer to the contents of a loop variable, which was later
overwritten in later iterations of the loop. Instead we now use HCL's
handy Ptr() method to create a direct pointer to the range struct.
Include the import walk in the list of operations for which we create an
EvalModuleCallArgument node. This causes module call arguments to be
evaluated even if the module variables have defaults, ensuring that
invalid default values (such as the common "{}" for variables thought of
as maps) do not cause failures specific to import.
This fixes a bug where a child module evaluates an input variable in its
locals block, assuming that it is a nested object structure. The bug
report includes a default value of "{}", which is overridden by a root
variable value. Without the eval node added in this commit, the default
value is used and the local evaluation errors.
If somehow an invalid workspace has been selected, the Meta.Workspace
method should not return an error, to ensure that we don't break any
existing workflows with invalid workspace names.
We are validating the workspace name for all workspace commands. Due to
a bug with the TF_WORKSPACE environment variable, it has been possible
to accidentally create a workspace with an invalid name.
This commit removes the valid workspace name check for workspace delete
to allow users to clean up any invalid workspaces.
