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.
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.
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 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.
Most of the state package has been deprecated by the states package.
This PR replaces all the references to the old state package that
can be done simply - the low-hanging fruit.
* states: move state.Locker to statemgr
The state.Locker interface was a wrapper around a statemgr.Full, so
moving this was relatively straightforward.
* command: remove unnecessary use of state package for writing local terraform state files
* move state.LocalState into terraform package
state.LocalState is responsible for managing terraform.States, so it
made sense (to me) to move it into the terraform package.
* slight change of heart: move state.LocalState into clistate instead of
terraform
A lingering FIXME caused missing configuration from provider config
blocks in the json output of terraform plan. This fixes the regression
and adds a test. For the sake of testing, I added an optional attribute
to the show test provider, which resulted in the providers schema test
getting an update - not a bad addition, but we can always add a
test-specific provider schema as needed.
For Terraform v0.12 we introduced a special loading mode where we would
use the 0.11-syntax-compatible "earlyconfig" package as a heuristic to
identify situations where it was likely that the user was trying to use
0.11-only syntax that the upgrade tool might help with.
However, as the language has moved on that is no longer a suitable
heuristic in Terraform 0.13 and later: other new additions to the
language can cause the main loader to disagree with earlyconfig, which
would lead us to give poor advice about how to respond.
Instead, we'll now return the same generic "there are errors" message in
all syntax error cases. We have an extra message for errors in this
case (as compared to other commands) because "terraform init" is usually
the first command a new user interacts with and so this message gives some
extra explanation about what "terraform init" will do with the
configuration once it's valid.
This also includes a reset control character in the output of the message
as part of our ongoing mission to stop Terraform printing out whole
paragraphs of colored text, which can often be hard to read for various
reasons.
After installing providers, we validate the presence of an executable
file, and generate a selected versions lockfile. If this process fails,
notify the user. One possible cause for this is an invalid provider
package with a missing or misnamed executable file.
* command/init: return an error with invalid -backend-config files
The -backend-config flag expects a set of key-value pairs or a file
containing key-value pairs. If the file instead contains a full backend
configuration block, it was silently ignored. This commit adds a check
for blocks in the file and returns an error if they are encountered.
Fixes#24845
* emphasize backend configuration file in docs
Previously, any comments inside the required provider configuration for
a given provider would be wiped out upon rerunning the 0.13upgrade
command. This commit attempts to preserve those comments if the existing
entry is semantically equivalent to the entry we are about to write.
This new version permits omitting the space between the operator and the
boundary in a ruby-style version constraint, like ">1.0.0" instead of
"> 1.0.0".
When initializing a configuration which refers to re-namespaced legacy
providers, we attempt to detect this and display a diagnostic message.
Previously this message would direct the user to run the 0.13upgrade
command, but without specifying in which directories.
This commit detects which modules are using the providers in question,
and for local modules displays a list of upgrade commands which specify
the source directories of these modules.
For remote modules, we display a separate list noting that they need to
be upgraded elsewhere, providing both the local module call name and the
module source address.
Providers can be required from multiple sources. The previous
implementation of the providers sub-command displayed only a flat list
of provider requirements, which made it difficult to see which modules
required each provider.
This commit reintroduces the tree display of provider requirements, and
adds a separate output block for providers required by existing state.
Fetching a default namespace provider from the public registry can
result in 404 Not Found error. This might be caused by a previously-
default provider moving to a new namespace, which means that the
configuration needs to be upgraded to use an explicit provider source.
This commit adds a more detailed diagnostic for this situation,
suggesting that the intended provider might be in a new namespace. The
recommended course of action is to run the 0.13upgrade command to
generate the correct required_providers configuration.
Relying on the early config for provider requirements was necessary in
Terraform 0.12, to allow the 0.12upgrade command to run after init
installs providers.
However in 0.13, the same restrictions do not apply, and the detection
of provider requirements has changed. As a result, the early config
loader gives incorrect provider requirements in some circumstances,
such as those in the new test in this commit.
Therefore we are changing the init command to use the requirements found
by the full configuration loader. This also means that we can remove the
internal initwd CheckCoreVersionRequirements function.
If a configuration had multiple blocks in the versions.tf file, it would
be added to the `rewritePaths` list multiple times. We would then remove
it from this slice, but only once, and so the output file would later be
rewritten to remove the required providers block.
This commit uses a set instead of a list to prevent this case, and adds
a regression test.
Instead of using providers.tf as the default output file for the
upgrader, we now default to versions.tf. This means that if the
configuration has no `required_providers` blocks at all, or has
multiple, the provider version requirements will be stored in the
versions.tf file.
We now also update the versions.tf file to set a `required_version`
attribute in the first `terraform` block, with value ">= 0.13". This
is similar to the behaviour of the 0.12upgrade command, and signals that
the configuration should not be used with older versions of Terraform.
This commit implements most of the intended functionality of the upgrade
command for rewriting configurations.
For a given module, it makes a list of all providers in use. Then it
attempts to detect the source address for providers without an explicit
source.
Once this step is complete, the tool rewrites the relevant configuration
files. This results in a single "required_providers" block for the
module, with a source for each provider.
Any providers for which the source cannot be detected (for example,
unofficial providers) will need a source to be defined by the user. The
tool writes an explanatory comment to the configuration to help with
this.
Providers like Okta and AWS Cognito expect that the PKCE challenge
uses base64 URL Encoding without any padding (base64.RawURLEncoding)
Additionally, Okta strictly adheres to section 4.2 of RFC 7636 and
requires that the unencoded key for the PKCE data is at least 43
characters in length.
* Include eval in output walk
This allows outputs to be evaluated in the evalwalk,
impacting terraform console. Outputs are still not evaluated
for terraform console in the root module, so this has
no impact on writing to state (as child module outputs are not
written to state). Also adds test coverage to the console command,
including for evaluating locals (another use of the evalwalk)
The providers command has been refactored to use the modern provider types and
ProviderRequirements() functions. This resulted in a breaking change to
the output: it no longer outputs the providers by module and no longer
prints `(inherited)` or `(from state)` to show why a provider is
included. We decided that at this time it was best to stick with the
existing functions and make this change, but if we get feedback from the
community we will revisit.
Additional tests to exercise providers in modules and providers from
state have been included.
This PR adds iteration through any provider configuration blocks in the
config in addProviderRequirements().
A stale comment (of mine!) would leave one expecting the
module.ProviderRequirements to include any requirements from provider
configs. The comment was inaccurate and has been updated.
Built-in providers are special providers that are distributed as part of
Terraform CLI itself, rather than being installed separately. They always
live in the terraform.io/builtin/... namespace so it's easier to see that
they are special, and currently there is only one built-in provider named
"terraform".
Previous commits established the addressing scheme for built-in providers.
This commit makes the installer aware of them to the extent that it knows
not to try to install them the usual way and it's able to report an error
if the user requests a built-in provider that doesn't exist or tries to
impose a particular version constraint for a built-in provider.
For the moment the tests for this are the ones in the "command" package
because that's where the existing testing infrastructure for this
functionality lives. A later commit should add some more focused unit
tests here in the internal/providercache package, too.
* command: refactor testBackendState to write states.State
testBackendState was using the older terraform.State format, which is no
longer sufficient for most tests since the state upgrader does not
encode provider FQNs automatically. Users will run `terraform
0.13upgrade` to update their state to include provider FQNs in
resources, but tests need to use the modern state format instead of
relying on the automatic upgrade.
* plan tests passing
* graph tests passing
* json packages test update
* command test updates
* update show test fixtures
* state show tests passing
missingPlugins was hard-coded to work only with provider plugins, so I
renamed it to clarify the usage.
Also renamed a test provider from greater_than to greater-than as the
underscore is an invalid provider name character and this will become a
hard error in the near future.
Implement a new provider_meta block in the terraform block of modules, allowing provider-keyed metadata to be communicated from HCL to provider binaries.
Bundled in this change for minimal protocol version bumping is the addition of markdown support for attribute descriptions and the ability to indicate when an attribute is deprecated, so this information can be shown in the schema dump.

If an error occurs on creating the context for console or import, we
would fail to unlock the state. Fix this by unlocking slightly earlier.
Affects console and import commands.
Fixes#23318
a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings).
The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN. This is fine for now as we are only working with default assumption.
There was an order-of-operations bug where the import graph builder was
validating that the provider did not have any resource references before
references were actually being attached. This PR fixes the order of
operations and adds a test (in the command package).
Fixes#22804
When a token is pasted by the user, we make a request to the
TFE API /account/details endpoint to verify its validity. If successful,
we display the logged-in username as confirmation. If not, we refuse to
store the invalid token and display an error message.
This commit also trims whitespace from around the pasted value, to
reduce the likelihood of a copy & paste error.
* deps: bump terraform-config-inspect library
* configs: parse `version` in new required_providers block
With the latest version of `terraform-config-inspect`, the
required_providers attribute can now be a string or an object with
attributes "source" and "version". This change allows parsing the
version constraint from the new object while ignoring any given source attribute.
