* Pull determining of PSS provider's version from current locks into a separate method
* Add code for identifying when config and provider version match existing backend state (i.e. no changes)
* Update test - locks are now needed before it hits expected error diag return
* Add test showing successful init when no config changes are detected.
* Update `getStateStorageProviderVersion` to return nil versions for builtin and re-attached providers.
This makes comparison easier when determining if config has changed since last init.
* Add test coverage for `getStateStorageProviderVersion`
* Move testing fixtures around, preparing for different types of changed state_store config changes being tested
* Add test showing that changing the state_store config is detected as a change, but handling this scenario isn't implemented yet
* Update hashes in test fixture backend state file to be accurate
Previously dummy values were fine, but as tests using hashes to identify changes these values need to be accurate!
* Update existing test cases so that Terraform uses the same test provider version as described in the backend state file fixture for the test.
* Add test showing that changing the PSS provider's config is detected as a change, but handling this scenario isn't implemented yet
* Add test showing that swapping to a different state storage implementation in the same provider is detected as a change, but handling this scenario isn't implemented yet
* Add test showing that changing the provider used for PSS is detected as a change, but handling this scenario isn't implemented yet
* Add test showing that upgrading a provider is detected as a change, but handling this scenario isn't implemented yet
* Update test to use v1.2.3 for consistency with other tests
Just to avoid any confusion if copy-pasting happens in future.
* More corrections to existing test fixtures - unset config should be null, and replace dummy hash values with correct values.
* Fix test for using -reconfigure with state_store; the default workspace would already exist in this scenario
* Update TestInit_stateStore_configUnchanged to assert that init was a no-op for backend state
* Remove unused fixture
* Remove test that's replaced by new tests in command/init_test.go
* Replace old references to deleted "state-store-changed" test fixture & update test to not expect a value for region attr in provider config
* Make test fixture coupling a little more understandable
* Refactor detection of no need to migrate into a function
* Add TODO about more involved provider version change tests
We will allow downgrades to succeed as long as the schema version number is unchanged
* Update (configs.StateStore)Hash method to return a single hash that's impacted by: state store config, provider config, state store type, provider source
* Update calling code and test helper code to reflect that the nested provider block no longer has its own hash
* Remove test; there is now a single hash that SHOULD be affected by the provider block!
* Also use provider name, from config, in hash
* Update tests to reflect changes in how hashes are made
* Remove unused `stateStoreConfigNeedsMigration` function
* Remove duplicate isProviderReattached function.
* Fixes to affected tests
* Allow provider version to impact the state storage hash, update impacted tests and test fixtures
* Update tests that now require locks data to be present in test setup
* Update comment for accuracy
* Fixes to other test fixtures - remove excess hash field, set hash to 0 to indicate they're not set accurately.
* Make upgrade test actually use upgrade code path
* Add lock files to test fixture directories that represent a project that's had a successful prior init using PSS
* Minor fixes in diagnostics
This can only be done once modules have been parsed and the required providers data is available. There are multiple places where config is parsed, into either Config or Module structs, so this needs to be implemented in multiple places.
* Rename test to make it specific to use of backend block in config
* Update initBackend to accept whole initArgs collection
* Only process --backend-config data, when setting up a `backend`, if that data isn't empty
* Simplify how mock provider factories are made in tests
* Update mock provider's default logic to track and manage existing workspaces
* Add `ProviderSchema` method to `Pluggable` structs. This allows calling code to access the provider schema when using provider configuration data.
* Add function for converting a providerreqs.Version to a hashicorp/go-version Version.
This is needed for using locks when creating the backend state file.
* Implement initial version of init new working directories using `stateStore_C_s`. Default to creating the default workspace if no workspaces exist.
* Update test fixtures to match the hashicorp/test mock provider used in PSS tests
* Allow tests to obtain locks that include `testingOverrides` providers.
The `testingOverrides` field will only be set in tests, so this should not impact end users.
* Add tests showing TF can initialize a working directory for the first time (and do the same when forced by -reconfigure flag). Remove replaced tests.
* Add -create-default-workspace flag, to be used to disable creating the default workspace by default when -input=false (i.e for use in CI). Refactor creation of default workspace logic. Add tests.
* Allow reattached providers to be used during init for PSS
* Rename variable to `backendHash` so relation to `backend` is clearer
* Allow `(m *Meta) Backend` to return warning diagnostics
* Protect against nil testingOverrides in providerFactoriesFromLocks
* Add test case seeing what happens if default workspace selected, doesn't exist, but other workspaces do exist.
The consequences here are due to using `selectWorkspace` in `stateStore_C_s`, matching what's done in `backend_C_r_s`.
* Address code consistency check failure on PR
* Refactor use of mock in test that's experiencing EOF error...
* Remove test that requires test to supply input for user prompt
This test passes when run in isolation but fails when run alongside other tests, even when skipping all other tests using `testStdinPipe`. I don't think the value of this test is great enough to start changing how we test stdin input.
* Allow -create-default-workspace to be used regardless of whether input is enabled or disabled
* Add TF_SKIP_CREATE_DEFAULT_WORKSPACE environment variable
* Responses to feedback, including making testStdinPipe helper log details of errors copying data to stdin.
Note: We cannot call t.Fatal from a non-test goroutine.
* Use Errorf instead
* Allow backend state files to not include version data when a builtin or reattached provider is in use.
* Add clarifying comment about re-attached providers when finding the matching entry in required_providers
* Report that the default workspace was created to the view
* Refactor: use error comparison via `errors.Is` to identify when no workspaces exist.
* Move handling of TF_ENABLE_PLUGGABLE_STATE_STORAGE into init's ParseInit func.
* Validate that PSS-related flags can only be used when experiments are enabled, enforce coupling of PSS-related flags when in use.
* Slight rewording of output message about default workspace
* Update test to assert new output about default workspace
* Add the ability to make a hash of state store config
* Add test demonstrating that the provider block doesn't impact the hash of a state_store block
* Make sure test asserts what would happen if the schema DID include the provider block
* Update the Hash method to return diagnostics, ignore nested provider blocks, and validate incoming schema and config
* Update tests to use more representative config, fix code under test as a result
* Update Hash method to return hashes for both the state_store and provider blocks
* Add test cases to cover how required fields are tolerated when making the hash
This is because ENVs may supply those values.
* Fix inaccurate comments
* Add test to show that hashes are consistent and exclude the provider block
* Update backend state file to contain hash of provider block's config
* Fix test to expect a hash for the provider config block.
* Fix bug in DeepCopy method, update test to have better error messages when diffs are detected
* Update test to explicitly check hash values
* Try make test intention clearer
* Improve user feedback when state store schema contains the protected word "provider"
* Update tests
* Update test to test the Hash method in a more true-to-life way
