Daniel Schmidt	c20bf67020	remove language experiment, this is guarded by being in an alpha release	7 months ago
Kristin Laemmert	386988cb50	Decode action blocks and action_triggers inside resource blocks. (#37030) ... * Decode action blocks and action_triggers inside resource blocks. This commit adds decoding of action and action_triggers inside terraform configuration. I added an Actions experiment as a hacky way of keeping the functionality out of main until we're ready for the alpha; this may never be an experiment but it's a handy feature flag so we don't have to do all the work in a long-lived feature branch. * remove legacy shim handling * validate that the referenced entry in actions is indeed an action	9 months ago
kmoe	fab3673f8d	lang: stabilise ephemeral values experiment (#35636) ... * lang: stabilise ephemeral values experiment Stabilise the ephemeral values experiment and ephemeralasnull experimental function. * simplify handling of apply time input vars As the final step in stabilising the ephemeral values experiment, we can remove the separate code path for handling input variables supplied via -var and -var-file during apply. The intent here is conveyed in the tests: when applying a saved plan, all ephemeral variables set in the plan (the "apply-time variables"), must be set, and no others. As per the TODO copied from the prototype, there is some more work to be done here in making the handling of undeclared variables during apply as sophisticated as that during plan, emitting helpful warnings (for example) when input variables are supplied unnecessarily via environment variables. * experiments: officially conclude EV experiment --------- Co-authored-by: Radek Simko <radek.simko@gmail.com>	2 years ago
Martin Atkins	1ef2ad7d4c	experiments: "ephemeral_values" language experiment ... This doesn't actually do anything yet, but in future commits it will enable some new language features for marking input variables and output values as "ephemeral", meaning that they don't get saved as part of state snapshots or saved plan files.	2 years ago

Martin Atkins	3b620bfe69	terraform: Stabilize the variable_validation_crossref experiment ... Previously we introduced a language experiment that would permit variable validation rules to refer to other objects declared in the same module as the variable. Now that experiment is concluded and its behavior is available for all modules. This final version deviates slightly from the experiment: we learned from the experimental implementation that we accidentally made the "validate" command able to validate constant-valued input variables in child modules despite the usual rule that input variables are unknown during validation, because the previous compromise bypassed the main expression evaluator and built its own evaluation context directly. Even though that behavior was not intended, it's a useful behavior that is protected by our compatibility promises and so this commit includes a slightly hacky emulation of that behavior, in eval_variable.go, that fetches the variable value in the same way the old implementation would have and then modifies the hcl evaluation context to include that value, while preserving anything else that our standard evaluation context builder put in there. That narrowly preserves the old behavior for expressions that compare the variable value directly to a constant, while treating all other references (which were previously totally invalid) in the standard way. This quirk was already covered by the existing test TestContext2Validate_variableCustomValidationsFail, which fails if the special workaround is removed.	2 years ago
Martin Atkins	847925b531	experiments: template_string_func experiment keyword ... This doesn't actually do anything yet, but we'll make it do something in a future commit.	2 years ago
Martin Atkins	ea67f2093f	experiments: variable_validation_crossref is a current experiment ... As of this commit this experiment doesn't actually change any behavior at all; as usual, those changes will follow in subsequent commits.	2 years ago
Nick Fagerlund	d5be799cb9	End unknown_instances language experiment, in favor of whole-plan option ... We're still iterating on the ability to defer unplannable changes to a later plan. However, instead of enabling it via a "contagious" experimental feature switch that can bubble up from any module, it's now behind a per-plan option in the PlanOpts struct. That option travels a winding path into the internals (see previous commit), and node execution logic can then access it during the plan walk via the `Deferred.DeferralAllowed()` method. This commit updates the spot where we switch between the deferral yea/nay code paths to respect this top-level plan option rather than the experiment flag.	2 years ago
Martin Atkins	78e2e20157	experiments: "unknown_instances" is a current experiment ... This doesn't do anything yet as of this commit, but in future commits it will gate the possibility for count and for_each arguments to have unknown values, which will then cause affected objects to have their planning deferred to a future run.	2 years ago

Martin Atkins	783a07d9e8	build: Use Go 1.19 ... Go 1.19's "fmt" has some awareness of the new doc comment formatting conventions and adjusts the presentation of the source comments to make it clearer how godoc would interpret them. Therefore this commit includes various updates made by "go fmt" to acheve that. In line with our usual convention that we make stylistic/grammar/spelling tweaks typically only when we're "in the area" changing something else anyway, I also took this opportunity to review most of the comments that this updated to see if there were any other opportunities to improve them.	4 years ago
Martin Atkins	b88e29e473	configs: Show tailored message for optional attrs experiment ... Since we've both concluded the module_variables_optional_attrs experiment and made experiments available only in alpha releases in the same minor release, we accidentally made the more general message about experiments not being available mask the specific message about the experiment being concluded. In order to give better feedback to those who were participating in the experiment in earlier Terraform releases, we'll retain a minimal exception to our checks to allow the "experiment has concluded" error message to shine through if and only if that is the only selected experiment.	4 years ago

Martin Atkins	94cbc8fb5d	experiments: config_driven_move has concluded ... Based on feedback during earlier alpha releases, we've decided to move forward with the current design for the first phase of config-driven refactoring. Therefore here we've marked the experiment as concluded with no changes to the most recent incarnation of the functionality. The other changes here are all just updating test fixtures to no longer declare that they are using experimental features.	4 years ago
Martin Atkins	6b8e103d6a	configs: Include "moved" blocks when merging multiple files into a module ... An earlier commit added logic to decode "moved" blocks and do static validation of them. Here we now include that result also in modules produced from those files, which we can then use in Terraform Core to actually implement the moves. This also places the feature behind an active experiment keyword called config_driven_move. For now activating this doesn't actually achieve anything except let you include moved blocks that Terraform will summarily ignore, but we'll expand the scope of this in later commits to eventually reach the point where it's really usable.	5 years ago
Kristin Laemmert	3acb5e2841	configs: add decodeMovedBlock behind a locked gate. (#28973) ... This PR adds decoding for the upcoming "moved" blocks in configuration. This code is gated behind an experiment called EverythingIsAPlan, but the experiment is not registered as an active experiment, so it will never run (there is a test in place which will fail if the experiment is ever registered). This also adds a new function to the Targetable interface, AddrType, to simplifying comparing two addrs.Targetable. There is some validation missing still: this does not (yet) descend into resources to see if the actual resource types are the same (I've put this off in part because we will eventually need the provider schema to verify aliased resources, so I suspect this validation will have to happen later on).	5 years ago
Martin Atkins	26e5320a78	Move experiments/ to internal/experiments/ ... This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.	5 years ago
