Sarah French	6b73f710f8	PSS: Implement initialisation of new working directory (or use of `-reconfigure` flag) while using `state_store` (#37732) ... * 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	4 months ago
Sarah French	b9522561c8	PSS: Add reusable method for obtaining the provider factory needed for accessing a state store. (#37665) ... * Add method to allow accessing factories from locks that are in memory * Create new getStateStoreProviderFactory method for accessing a factory from config * Update getStateStoreProviderFactory to use in memory locks instead of reading them from the deps lock file. Update calling code to accommodate this. * Add tests for getStateStoreProviderFactory, improve errors returned from method * Update test following schema change in simple providers * Move test case into e2etest package, so we protect against environments where building binaries isn't possible * Fix issues with running test in e2etest package * Update code comments Co-authored-by: Radek Simko <radeksimko@users.noreply.github.com> --------- Co-authored-by: Radek Simko <radeksimko@users.noreply.github.com>	5 months ago
Sarah French	8503c45013	Update `backend.Backend`'s `StateMgr` method to return diagnostics instead of primitive errors (#37496) ... * Fix S3 backend test affected by making the Workspaces method return errors via diagnostics * Address diagnostics comparison issues in test by ensuring expected diagnostics are defined in the context of the config they're triggered by * Fix failing test case `TestBackendConfig_EC2MetadataEndpoint/envvar_invalid_mode` by making `diagnosticBase` struct comparable * Add compile-time checks that diagnostic types fulfil interfaces * Stop diagnosticBase implementing ComparableDiagnostic, re-add S3-specific comparer code to s3 package * Update tests to use the S3-specific comparer again * Fix test case missed in refactoring * Update the backend.Backend interface to use diagnostics as return value from StateMgr method * Fix calls to `Fatalf`	6 months ago
Sarah French	da76dba3dc	PSS: Add alternative, experimental version of `init` command that downloads providers in two stages (#37350) ... * Add forked version of `run` logic that's only used if experiments are enabled * Reorder actions in experimental init - load in full config before configuring the backend. * Add getProvidersFromConfig method, initially as an exact copy of getProviders * Make getProvidersFromConfig not use state to get providers * Add `appendLockedDependencies` method to `Meta` to allow multi-phase saving to the dep locks file * Update experimental init to use new getProvidersFromConfig method * Add new getProvidersFromState method that only accepts state information as input for getting providers. Use in experimental init and append values to existing deps lock file * Update messages sent to view about provider download phases * Change init to save updates to the deps lock file only once * Make Terraform output report that a lock file _will_ be made after providers are determined from config * Remove use of `ProviderDownloadOutcome`s * Move repeated code into separate method * Change provider download approach: determine if locks changed at point of attempting to update the lockfile, keep record of incomplete providers inside init command struct * Refactor `mergeLockedDependencies` and update test * Add comments to provider download methods * Fix issue where incorrect message ouput to view when downloading providers * Update `mergeLockedDependencies` method to be more generic * Update `getProvidersFromState` method to receive in-progress config locks and merge those with any locks on file. This allows re-use of providers downloaded by `getProvidersFromConfig` in the same init command * Fix config for `TestInit_stateStoreBlockIsExperimental` * Improve testing of mergeLockedDependencies; state locks are always missing version constraints * Add tests for 2 phase provider download * Add test case to cover use of the `-upgrade` flag * Change the message shown when a provider is reused during the second provider download step. When downloading providers described only in the state then the provider may already be downloaded from a previous init (i.e. is recorded in the deps lock file) or downloaded during step 1 of provider download. The message here needs to cover both potential scenarios. * Update mergeLockedDependencies comment * fix: completely remove use of upgrade flag in getProvidersFromState * Fix: avoid nil pointer errors by returning an empty collection of locks when there is no state * Fix: use state store data only in diagnostic * Change how we make PSS experimental - avoid relying on a package level variable that causes tests to interact. * Remove full-stop in view message, update tests * Update span names to be unique * Re-add lost early returns * Remove unused view messages * Add comments to new view messages	6 months ago
Sarah French	f494ff5540	Pull `init` command's Run method logic into separate method in new file, enable accessing experimental version of init logic via experiments and flags or ENVs (#37327) ... * Pull `init` `Run` method into new method in a separate file, in preparation for adding experimental fork. * Add license header * Allow init args to be accessed before calling separate init run logic * Add -enable-pss flag to the init command, to be used for accessing experimental init logic * Fix- put call to `run` in else block! * Make flag name more explicit * Add an environment variable alternative to the CLI flag * Make the panic text more user-friendly * go fmt	7 months ago
