Sarah French	efb2a1c567	PSS: Let the `init` command recognise when there are no changes in configuration. (#37777) ... * 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	6 months ago
